Effect of Unethical Behavior Article Analysis Essay Example for Free

Effect of Unethical Behavior Article Analysis Essay The Sarbanes-Oxley Act, passed in congress in 2002 is designed to protect investors from the potential of fraudulent corporate accounting activities. This act strictly mandates reform, aimed directly to prevent fraud and improve corporate financial disclosures (INVESTOPEDIA, 2012). As a result of several confidence shaking investor accounting scandals that occurred during the late 90s which involved high profile corporations such as Enron, WorldCom and Tyco, a much required overhaul regarding financial statements and regulatory standards laid the foundation for the Sarbanes-Oxley Act. This act is making the accounting world more accessible to others for auditors to come in and help in checking the books. It will hold the executives and directors accountable for the internal controls of the company especially with the threat of imprisonment if the internal controls are not maintained. The act ensures that a â€Å"checks and balance† internal auditing of the accounting cycle for the company and investors to keep their assets in check. The role of internal audits is to ensure that Institute of Internal Auditor’s Standards for the Professional Practice of Internal Auditing Standard 300 Scope of Work be followed. The scope of the internal audit should encompass the examination and evaluation of the adequacy and effectiveness of the organizations system of internal control and the quality of performance in carrying out assigned responsibilities (M. Wood Company, 2012). The internal audit standards are to review the dependability and integrity of financial and operating information and the resource being used to identify measure and classify those reports. The standard requires the system be reviewed to ensure compliance with those policies, plans, procedure, laws and regulations which may have a huge impact on operations and reporting. The standard is used to review the methods in place to safeguarding assets and verify that the assets protected exist. The final purpose of the standard is to appraise the economy and the efficiency with the means that are employed by a corporation. It is important to note that policies and rules are also enforced to uphold the Sarbanes-Oxley Act. Sections 302, 401, 404 and 805 in particular address key requirements as it pertains to effecting financial statements. Section 302 requires senior managers to certify the accuracy of the reports along with establishing internal controls are set in place for the purpose of increasing report accuracy, ensuring honesty and ultimately providing financial protection for the investors. Section 401 ensures that statements may not contain fraudulent information. Section 404 provides for the necessary rules for annual reporting as well as addresses management auditing structures. Lastly, section 805 provides the guidelines for federal sentencing relating to criminal fraud and obstruction of justice. (Hazels, Nov/Dec) A very important question that should be asked is how well main stream America understands the Sarbanes-Oxley Act of 2002 and how it has effected them? Another pressing area to uncover is how it has affected the US economy over the past ten years? Lastly, it would be interesting to understand how US companies interface globally with countries not held to the same standards. References Hazels, B. (Nov/Dec 2010).

Asthma and the Buteyko Breathing Technique (BBT)

Asthma and the Buteyko Breathing Technique (BBT) Introduction Lung disease is any pathology that occurs in the lung components and causes the lungs not to function properly and this may lead to serious problems that may cause death. They are considered the third killing factor worldwide. Lung diseases include emphysema , bronchitis, bronchial asthma, pulmonary failure, pneumonia, tuberculosis and pulmonary embolism. These diseases have the following signs and symptoms which are coughing , dyspnea, short breaths, noisy breath sound, fever, chest pain , and using accessory muscle of the neck which include scalene, upper trapezium and sternocleidmastoid muscles. The common causes of these lung diseases are smoking, infections, and genetics factors (Simon,2000) .Treatment of lung disease includes medications like corticosteroid, bronchodilators, antibiotics, and physical therapy that will give patients breathing exercises. One of the most common chronic obstructive disease, is bronchial asthma. Bronchial asthma is the fifth reason for hospitalized worldwide. Physiotherapists used to treat bronchial asthma patients who have hyperventilation symptoms using breathing exercises known as buteyko breathing technique (BBT) in additional to bronchial asthma therapy.(Bishop,2007) Background Professor Konstantin Buteyko was a Russian physiologist (1932-2003) , who gave his name to a treatment for bronchial asthma patients. The whole idea started in 1960s when he came with the idea that shallow breathing is going to help patients who suffer from hyperventilation like bronchial asthma and stenocardia. He suggested that hyperventilation lead to decrease the amount of blood that is going to alveoli and low- level of CO2 lead to bronchoconstriction which increase hyperventilation. (Bishop,2007) Literature Review Robert L. and other on 2007 tried to evaluate the efficiency of a non -pharmacological intervention Buteyko Breathing Technique (BBT) in patients with asthma with their corticosteroid medication consumption. The design of the study was a randomized control trail of buteyko technique involving 182 subject divided into group of adult with asthma their age ranged from 18-50 years old. While the control group was trained by physiotherapy for relaxation breathing technique. The main results measures by level of asthma control, defined by composite score based on Canadian asthma consensus reported 6 months after completion of intervention. The consequences show that both groups had related enhancement and a high amount with asthma control six months after accomplishment of the intervention. In the Buteyko group the degree with asthma control increased from 40% to 79% percent and in the control group from 44% to 72%. The main conclusion that six month after completion of the intervention, a large majority of subject in each group shown control of their asthma with the additional benefits of lessening in inhaled corticosteroid use in buteyko group.(Robert, 2007) McHugh on 2003 made a study to evaluate the impact of buteyko breathing technique (BBT) on medication consumption in asthma patients. The method used is a blinded randomized control trail comparing BBT with medication control . It was directed over 38 people with asthma aged between 18-70 years. Members were followed for six months. Medication use and tempts of ventilator function were recorded. The results exhibited that BBT group shown a lessening in inhaled steroid use of 50% only and beta-agonist use 85% after six month from intervention. In the control group there was no significant outcomes. The main conclusion that BBT is a safe and effective for asthma controlling for it is sign and symptoms. BBT has clinical and potential pharm-economics benefits that must have advance studies.(McHugh, 2003) Cooper and his colleges in 2003 completed a study to compare the effect of two breathing exercises which they are buteyko and pranayma which is a yoga breathing method for bronchial asthma patients. This study involve 90 grown-ups who complain of asthma and control it by using medications. They were divided into three groups First group follow buteyko breathing technique ,the second group use a pranayma which is a yoga technique and the last group were the placebo group. Result measure used are symptoms score level , bronchial hyper reaction, medication used, forced expiratory volume before and after buteyko technique. The results showed that ( p=0.003) were the mean for buteyko group and bronchodilator uses have been lessened by two puffs/day after 6 month of practicing buteyko technique while there was no change in the mean in the other two groups. There wasnt difference in the forced expiratory volume or even volume to reduce inhaled corticosteroids. The main conclusion that BBT c an recover symptoms and lessen bronchodilator use but doesnt seem to change bronchial responsiveness or lung function in patients with asthma.(Cooper, 2003) Anatomy of Respiratory System When we breathe air it go through nose to the lower respiratory tract. The advantage of nose breathing is that when air passes through the nose it will be moisturizer, heated and cleaned from any dust. After that air moves to larynx to go into trachea. Trachea is a sensitive structure because if any cold or dry air go into it , this will cause coughing and wheezing as normal interaction to these irritation .After that air moves from the trachea to the lung through the bronchi which are entered in each lung (Figure 1). The lungs are the most important part of human respiratory system. The right lung is divided into three lobes m while the left lung is divided into two lobes. Both lungs are protected by the chest wall. In the lung small air sacs known as alveoli . Then the gases exchanged from the alveoli to the blood stream through small blood vessels known as capillaries. On the other hand , the body waste CO2 returns to the capillaries to be exhaled during breathing. Healthy bronchi al tubes make rapid gases exchange to maintain unchanged level of O2 and CO2 in the blood stream. The outer surface of bronchi is surrounded with smooth muscles that contract , relax in smooth rapid way in each breath. This process will maintain the required amount of air that is needed to go into lung tissues for normal gases exchange. This process of contraction and relaxation of muscles in controlled by sympathetic and parasympathetic of nerves system.(Gerard J,2005) What is Bronchial Asthma One of the most common chronic obstructive pulmonary diseases (COPD) is bronchial asthma. Bronchial asthma is a chronic inflammation of lung airways that leads to swelling and narrowing of them. The results of this narrowing is difficulty in breathing. The narrowing of airways may be total or partial and can be reversed with treatments. Bronchial asthma is one of the most common diseases , it affect one in every 15 adults in United states of America. It is known to cause physiologically reversible or total obstruction or narrowing to air . Pathologically this will increase thickening of airways because of inflammation and bronchoconstriction. Also narrowing of airways maybe due to swelling which is caused by immune response to allergic materials. (Gerard J,2005) Causes of Bronchial Asthma The main cause of bronchial asthma is inflammation of lung airways that is increased by the increase of irritable stimulations such as dust, vapor, humid weather, cold air, smoke , air pollutions, and fumes.(Gerard J, 2005) Sign and Symptoms of Bronchial Asthma Bronchial asthma have major sign and symptoms that are diverse depending on the severity of the disease. These signs and symptoms include wheezing that is defined as a whistling , hissing sound when exhaling air. Prolonged Coughing, that is usually at night not as good as at early morning, and may occur after workout or when unprotected against cold or dry air. Fast breathing is another symptom of bronchial asthma because fewer air reaches the lungs which is the reasons fast breathing to make up the insufficiency. Another symptoms is the usage of accessory muscle of neck and upper shoulder. Palpitation is another symptoms which is caused by as an asthma attack become worse the airways forceful air through the narrow airways become harder. Muscles of your trunk start to help. This is seen in motion (Figure 3) of the esophagus (2), and sucking in of the abdominal just under the breast bone (5) and among the ribs (4) with each breath leading to heart palpitation. As a response to less a ir passing through inflamed airways that will cause body to do more strength to move air and due to that heart starts to contract faster (3).( Gerard , 2005) Prevention of Bronchial Asthma Bronchial asthma can be prevented by following these strategies: Always check with medical physician for treatment plan to mange signs and symptoms for bronchial asthma . Know the trigger of asthma to be avoided such as pollen air and cold air . Always monitor their breathing type so that they can recognize early symptoms of asthma attack that include coughing, wheezing or shortness of breath. Quickly treat of bronchial asthma attack with immediate taking of medications prescribed and stopping the activity that may be the cause to trigger the attack. (Sue ,2002) Treatment of Bronchial Asthma Bronchial asthma can be treated by different types of medications like corticosteroids, bronchodilators, antibiotics, and by physical therapy. One of the important technique that help patients to control signs and symptoms of bronchial asthma is the Buteyko Breathing Technique (BBT) .( Sue , 2002) What is Buteyko Breathing Technique Buteyko technique is a breathing regulator technique to reduce minute ventilation besides inhibit hyperventilation to treat bronchial asthma as an alternative approach ,besides to the drugs used. Buteyko technique needs that breathing originates from diaphragm not mouth. The main purpose while practicing buteyko breathing style is to breath in a very controlled and shallow manner without holding in the air like your last breath, it should be a gentle rhythm of breathing in and out.(Bruton,2003) Preparation For Buteyko Breathing Technique Before starting the Buteyko Breathing technique session the physiotherapist should first takes patient pulse per minute and ability to exhale through Forced Expiratory Spiro-meter and measure the blood pressure and check if the patient have any health problems that may be contraindicated to buteyko breathing technique. Also it is important to take full medical history of management of patient bronchial asthma that usually includes hospital admission , consultant referrals and type of medication taken and their dosage. Also check if patient take other medication for other medical conditions. Physiotherapist should also check main signs and symptoms that affecting the patients daily work as if climbing stairs that increase shortness of breath to the patient. After that physiotherapist should inform bronchial asthma patient that buteyko session can be practiced three to five times a day . Before starting buteyko breathing technique session the physiotherapist should educate patient that this technique focus on breathing from the nose, so that nose clearness exercises should be given before starting session (Figure 5). The nose clearance exercises include pinching the nose gently and then move head forward and backward. Usually starting position will be sitting on chair without armrest after that progress to lying supine and finally to make patient adapt to this technique to be practiced in all active daily living of patients life, like climbing stairs. (kellet,2005) Steps of Buteyko Breathing Technique The Procedure of Buteyko Breathing Techniques is characterized by the following steps: Step 1: Close your mouth and breathe from the nose to get all the advantages mention before of nose breathing. (Figure 6).This step may be hard to be followed in the beginning but with practice it became easier with training. Step 2 : Use diaphragm to during breathing in and out , when patients practice breathing using diaphragm they should take in consideration to eliminate using of accessory muscle of neck and upper chest . (Figure 7). Step 3: Measure control pause for bronchial asthma patient , which is the time that patient able to grasp the nose and avoid air entry until the first feel of needing to re-breath again in the same way and pattern . ( Figure8) can be measure using stop watch. Step 4: Sit in an upright position and reduce breath for around 2 3 minutes, after that bronchial asthma patient will take short rest for 20-30 second and followed by another reduce breathing period for 3 minute followed by short rest again. Step 5: After the last short rest ,the physiotherapists check the final control pause again to check progress in amount of time patient able to hold breath. Usually in first session patient will able to increase time of control pause 2-3 seconds.(Oliver, 2009) Physiological Effects of Buteyko Breathing Technique During an asthma attack people start to panic and breath faster more than body demands. They actually over breathe because they are breathing so rapidly that causes the amount of carbon dioxide in the blood to fall too low. The body responds to that by causing the airways of the lungs to become tighter which leads to decrease inhaled air in each breathe which is shown when bronchial asthma patients trying to breathe harder. This technique will help to break this negative feedback cycle by educating bronchial asthma patients to breath in a shallow way and this will lead to decrease the amount of air that reach lung during breathing. Another benefit is increasing tolerance of body for higher levels of carbon dioxide in your blood.(Oliver,2009) Who will benefit from Buteyko Breathing Technique Buteyko breathing technique is suitable for bronchial asthma patients and some other conditions that lead to hyperventilation such as hay fever , which is allergic and inflammation due to dust , rhinitis which is also known as stuffy nose that happen due to inflammation of inner nose parts. Buteyko breathing technique can be included also for nose congestion, panic attack, resent heart, persistent cough, bronchitis, snoring and last for COPD patients .(Oliver,2009) Contraindications for Buteyko Breathing Technique Patients with these conditions will not be able to practice BBT even if they have bronchial asthma or any other condition that lead to hyperventilation . These conditions include kidney failure specially if patient on dialysis, current organ transplant, previous brain hemorrhage, recent heart attack or stroke, cardiac peacemaker device, active stomach ulcer, pregnancy, schizophrenia, uncontrolled high blood pressure, any current cancer treatment, sickle- cell anemia and sever emphysema with heart failure. (Oliver,2009) Conclusions Asthma is a common lung disease around the world and usually patients suffer from a lot of sign and symptoms like attacks of shortness of breath, chest tightness, and coughing that may affect their quality of life so that it need pharmacological agents to control it beside non-pharmacological techniques of pulmonary rehab such as buteyko technique. Buteyko breathing technique is a complementary method that proven it is effectiveness to control breathing in hyperventilation cases such as asthma and improve their quality of life, level of exercises, and forced respiratory volume. There are five core components of the buteyko breathing technique that they are the nose breathin , relax upper muscles, use diaphragm breathing, small gentle breaths and maintain good posture. The buteyko exercises can be done 3-5 times a day and it need committed for these exercises and make lifestyle changes, to be able to use fewer medication.

The Turning Point of World War II - The Battle of Midway Essay example

World War II, along with its numerous battles, brought great tension between two of the strongest countries during the 1940s: the United States and Japan. Conflict between these two countries started with Japan’s push past Chinese borders into Manchuria in search of the natural resources Japan lacks. At first, the United States avoided military action with Japan by waging economic warfare on them. This economic pressure included the passing of the Neutrality Act, which prohibited the sale of weapons to nations at war (Nash 513). Additionally, the United States placed oil embargoes on Japan hoping it would force Japan to shut down military operations in China. Japan, at a critical decision point, decided to bomb the American naval base at Pearl Harbor. On December 7th, 1941 at 6 a.m., Japan pilots bombed the naval base at Pearl Harbor, taking out the United States’ strongest battleships, killing thousands of people, and destroying hundreds of planes (Sherman). The day a fter Pearl Harbor, the United States declared war on Japan. Over the next few years, the United States and Japan fought fierce battles for dominance in the Pacific Ocean. One of the most important battles during the United States and Japanese war was the Battle of Midway. Japan was destroying the United States at sea, until the Battle of Midway gave the United States Pacific Fleet an edge on Japanese forces. The Battle of Midway was the most important naval engagement of World War II: it was a decisive battle that allowed the United States to be the dominant naval power in the Pacific and it marked a turning point in World War II for the United States. The motive for Japan’s plan to attack Midway Island was to claim dominant power over the Pacific Ocean and to... ...ary B. American Odyssey: The United States in the 20th Century.

Marriage Matters Summary Linda J, Waite

As a preface, Waite progresses through various statistics fostering today's pattern of decreased marriages. She states clearly that, â€Å"The decline in marriage is directly connected to the rise in cohabitation-living with someone in a sexual relationship without being married. † Statistics showed a vast decrease in marriages between both black and white marriages. This seems to be an epidemic in today's society providing examples which might reflect people or situations In our lives.Another one, of the many, shocking statistics show that about â€Å"one third† of births occur outside of wedlock. Waiter's worry is that marriages are statistically more beneficial to the children who are conceived and born with a stable set of parents. The first argument poses a stance that health between a family is of greater quality when the family Is complete. That being said, Waite never quite defined what a complete family Is, but the term Is connotatively a derived of a mother, f ather, and could possibly consist of children.From the paper, a family Is anything Inside matrimony. Waiter's first argument for health is that marriage appears to reduce risky and unhealthy behaviors. Marriage will also increases material well-being such as income, assets, or wealth. The last component, which I think is the most beneficial, is moral support. All of these ideals are intricate measures needed for a healthy life-all of which stem and are heightened through marriage. The second argument for a pro marriage lifestyle is that life Is easier financially through a stable Income.Incomes can either be shared or enhanced with marriage. Waite argues that single parent households are in Jeopardy due to lack of sufficient funds and energy where dual parent homes are either amplified by double income or saved by production at home. Wives tend to lead the stay at home Job of doing the duties with house work while men go to work. This leaves more time to pay attention to family as w ell as diligence In their career while the wife rears the kids and does house work; leaving much more time to relax and recoup.The third argument supported by Waiter's article supports a greater intimacy between a couple in marriage. When people think of the word intimacy, it is attached (generally) to sex. Waite argues that not only are sexual needs exceeded, but emotionally the bond is wound tighter. â€Å"The long term contract implicit in marriage- which is not implicit in cohabitation- facilitates emotional investment in the relationship, which should affect both frequency of and needs are met. The final argument is the impact of marriage on the children.Statistics show that two times as many children that are raised in one-parent families than children from two-parent families drop out of high school. A startling fact but is upheld to be true. Almost all cases of poverty were recorded by cases of children growing up in single parent homes. It summates that children are superb ly affected by the role models which are designated in their lives. The last page of the article persuades the reader to â€Å"reverse the trend† and all of the casualties invested by overdeveloped monogamous relationships.Multiple sources are accredited with the foundation of a rubber standard. The ideals in society fluctuate because of public policy and acceptance. Policies and standards must be enforced throughout society to rectify change. In summate, Waite argues that a positive lifestyle is that of which is inside of marriage. She resolves that â€Å"marriage produces individuals who drink less, smoke less, abuse substances less, live longer, earn more, are wealthier, and have children who do better- need to give more thought and effort to supporting this valuable social institution. †

Creation Of Heavens And Earth In Six Days Religion Essays

Creation Of Heavens And Earth In Six Days Religion Essays Creation Of Heavens And Earth In Six Days Religion Essay Creation Of Heavens And Earth In Six Days Religion Essay The Quran revealed certain scientific truths with respect to the motion of the celestial organic structures in the 7th century A.D. , when superstitious notion and fabulous thoughts ruled supreme and when scientifically the habitable universe was in entire darkness. These disclosures have now been established as scientific truths. Before foregrounding them it is proposed to explicate the Quranic averment that Allah created the celestial spheres and the Earth in six yearss, ( Al-Araf, The Heights, VII: 54 ) . These six yearss symbolise heavenly yearss and are non to be treated like the normal six yearss of the hebdomad in our calendar. Harmonizing to the Qur an the continuance of each heavenly twenty-four hours may run between 1000 and 50,000 old ages. As for case in Surah Al-Sadah, ( The Prostration, XXXII: 5 ) , it is pointed out that He regulations ( all ) personal businesss from the celestial spheres to the Earth: in the terminal will ( all personal bus inesss ) go up to Him on a Day the infinite whereof will be ( as ) a thousand old ages of your calculation. In Surah Al-Maarij, The Ways of Ascent, ( LXX: 4 ) . The angels and the Spirit ascend unto Him in a Day the step whereof is ( as ) 50 1000 is old ages . In the visible radiation of this overly long continuance of the heavenly yearss one tends to hold with Maurice Bucaille that the word yearss should be taken to intend Time periods ( p. 140 ) . Abdullah Yusuf Ali besides insists that the six yearss referred to in the Quran signify phases in the Creation and that the Quranic yearss ( yawm ) should be interpreted to intend really long periods, or Ages or Aeons. ( Maurice Bucaille, p. 142 ) . Thus the procedure of the creative activity of Eden and Earth in six yearss has to be perceived in the visible radiation of the foregoing elucidation. The creative activity of the Earth is non to be viewed in isolation. Mention to its creative activity implies the creative activity of the solar system which harmonizing to the Quran was created in two heavenly yearss Say: Is it that ye deny Him who created the Earth in two Dayss ( Fussilat, XLI: 9 ) . The Quran conceives of an incorporate system of the Universe including the solar system and the system of galaxies. This procedure was started at the same time with the creative activity of the Earth or the solar system and is implied in the undermentioned Quranic poetries: the celestial spheres and the Earth were joined together ( as one unit of Creation ) before we clove them asunder. ( Al-Anbiyii, The Nebiims, Twenty-one: 30 ) . Subsequently they were integrated into a good knit system: Furthermore He comprehended in His design the sky, and it had been ( as ) fume: He said to it and to the Earth: Come ye together, volitionally or unwillingly. They said: We do come ( together ) in willing obeisance, ( Fuussilat, XLI: 11 ) . This procedure of cloving asunder and coming together of the galaxies, solar system and the seven celestial spheres as portion of a incorporate system was accomplished at the same time in two heavenly yearss. In order to grok their right significance and significance the two poetries 12 and 9 of Sirah Fussilat ( XLI ) have to be read together. Any spread between the procedure of separation and integrating will do the outgrowth of an interlinked gallactic and solar system practically hard. This separate mention to two yearss in each of the two poetries ( 9 and 12 ) imply the same time-span and non extra two yearss. This coincident happening is besides implied in the undermentioned poetries. So. He completed them as seven celestial spheres in two Dayss, and He assigned to each Eden its responsibility and bid. And We adorned the lower Eden with visible radiations, and ( provided it ) with guard ( Fussilat: XLI: 12 ) . The Creation of stars in the lower Eden is besides pointed out in Surah Al-Saffat, Those Ranged in Ranks ( XXXVII: 6-7 ) : We have so decked the lower Eden with beauty ( in ) the stars, ( for beauty ) and for guard against all obstinate rebellious evil liquors. It is hence clearly clear that the seven celestial spheres, the galactic and the solar system were raised at the same time and were interlinked as portion of the system of Universe within the same infinite of clip and non in two different heavenly periods. The Quran farther reveals in these poetries that each of the seven celestial spheres has been assigned specific functions without spelling them out. This has been done presumptively to excite the wonder of adult male in order to actuate him to examine into the enigmas of the Universe. However, this disclosure once more stresses the point that there is ever a well defined intent in all Divine creative activities. In the staying four heavenly yearss of creative activity the Earth was set in order and made habi table for adult male: He set on the ( Earth ) , mountains standing house, high above it, and bestowed approvals on the Earth, and measured in this all things to give them nourishment in due proportion in four Dayss in conformity with ( the demands of ) those who seek ( nutriment ) ( Fussilat, XLI: 10 ) . The recession of the galaxies which is now steadfastly established by Hubble s Law and Red Shift, and which implied enlargement of the Universe is besides clearly indicated in the Quran: With power and accomplishment did We build the Celestial sphere: For it is We Who create the enormousness of Space, ( Al-Dhariyat, The Winds that Scatter, LI: 47 ) . As indicated by the Big Bang Model the Universe will be annihilated at a peculiar point of clip through the procedure of implosion ( the large crunch ) , the Quran really decidedly proclaimed it in Surah Ahqaf, Winding Sand Tracts ( XLVI: 3 ) : We created non the celestial spheres and the Earth and all between them but for merely terminals, and for a term appointed. This is besides emphasised in Surah Al-Zumar, The Crowds, ( XXXIX: 5 ) : He has subjected the Sun and the Moon ( to His jurisprudence ) : Each follows a class for a term appointed. This term appointed presumptively refers to the large crunch, which harmonizing to th e Big Bang Theory will end the Universe. Harmonizing to the Quran this will be the ( Day ) of Noise and Clamour ( it is ) a Day whereon work forces will be like moths scattered about and the mountains will be like carded wool. Day of Noise and Clamour. Curie: 1-5 ) . This description in the Quran of the Last Day of Judgement clearly intimations at the breakage of all scientific Torahs -which Hawking besides pointed out in the undermentioned words: At the Big Bang and other uniquenesss, all the Torahs would hold broken down ( PL, 183 ) . It is therefore clear that what the uranologists have discovered now as scientific truth the Quran announced it 14 hundred old ages ago and can be justly termed as its scientific miracles.

Strategy for Introducing a New Product Research Paper

Strategy for Introducing a New Product - Research Paper Example The company has loyal customers in the market because of its persistence. Today, it is still a dominant player in the tea industry in most of its countries. Tetley is just about to introduce a new product into the market. However, before the launch, the company needs to establish whether the market will accept the new product. In addition, the company needs to identify the specific target in the market. This paper will examine the market trends in order to provide the answers to these issues. Tetley has had immense impact in the market. It is through their marketing strategies that they have managed to win a large market share. Through this therefore, the company owns the credit for innovating tea bags in the early 1900s although the venture came after accidental realization that tea bags were a possibility in packaging. The company has its roots in the United Kingdom where its founders started out venture. The company has posted growth in several other countries. Despite the competi tion that has grown over time as new entries in the tea industry, Tetley tea still dominates the United Kingdom market. Tetley group has several sister companies operating separately. The entire sister companies offer unique brands to the region in which they operate. In 2011, Tetley dominated the market achieving 24% retail value in Canada. Tea products had a retail growth value of 4%. The volume growth in the same year was 1 %. The Canadian market posted C$ 547 million. The Canadians prove to be a good market for tea. They easily try out new tea products with the right persuasion (Masterson and Pickton, 2010:85). Tetley’s products did well in the Canadian market with black tea special brand scooping a 44% share followed by green tea with 31% while standard black tea got 18 %, which was a one percent rise from 2010. In addition, the herbal tea and fruit ranges of products as well as the color therapy proved a real success in the Canadian market. Future prospects indicated a growth in tea sales by 2016. In the United Kingdom, tea prices recorded an increase in 2010. Black tea made more sales in the market though it portrayed minimal growth. Herbal and green tea exhibited more growth in the market because of the health benefits. 12% of total sales of tea were the herbal and green tea. Most of the sales of tea were to people above 65 years accounting for 88% of consumption. Tea consumption was relatively lower for the younger generation. Tea is receiving competition from other products among the younger generation and the 90% breakfast tea sales were going down. The trends in 2011 changed because of the campaigns on the benefits of tea. This year saw Unilever take a lead in the percentage of sales. In the United States of America, tea exhibited an increase in popularity in 2011 because of the increased awareness of tea benefits on health. Tea posted a growth of 2% reaching 72278 tonnes. In this market, Unilever was leading in the percentage of sales. The tea industry in America is likely to show a 10% growth by 2016. The healthier products such as herbal tea, iced tea, and fruit-varieties stand a chance to indicate growth because of the health benefits (Masterson and Pickton, 2010: 86). The Indian market trends portrays that black tea, the standard variety still dominates because of the Indian cultural and traditional set up (Pride et al, 2011:131).

Social Media Essay Example | Topics and Well Written Essays - 1500 words

Social Media - Essay Example Michael Haenle in and Andreas Kaplan describe social media to mean "a set of Internet-based appliances that exploit the technological and ideological basics of Web 2.0, as well as permit the formation and interchange of user-generated information (2010). Additionally, social media hinges on web-based and mobile technologies to form extremely interactive programs through which communities and individuals co-create, share, discuss, as well as transform user-generated information. It initiates pervasive and significant transformations to communication among organizations, individuals and communities. Social media is different from industrial or traditional media in numerous aspects, for instance, reach, permanence, quality, frequency, immediacy, and usability. Social media technology takes on numerous different varieties including Internet forums, magazines, social blogs, weblogs, wikis, micro blogging, social networks, pictures or photographs, podcasts video, rating as well as social b ookmarking. Through applying a collection of concepts in the arena of social processes and media research, Haenlein and Kaplan formed a classification system in their Corporate Horizons (2010) article. They used six varied kinds of social media: micro blogs and blogs (for instance, Twitter), collaborative projects (for instance, Wikipedia), content communities (for instance, Daily Motion and YouTube), and social networking websites, for instance, Facebook. Others include virtual social worlds (for instance, Second Life), simulated game worlds (for instance, World of War craft).The technologies comprise blogs, wall-postings, picture sharing, email, vlogs, instant messaging; voice over IP and crowd sourcing, and music sharing. Much of these packages can be assimilated through social network accretion programs. Social media net websites comprise sites like, Twitter, Facebook, Viadeo, Vkontakte, Tuenti, Hyves, Daniel's World , Dreams village, MySpace, and Bebo. Once social media is appl ied in sequence with mobile gadgets it is termed as mobile social-media. Therefore, social media is a set of mobile promoting applications, which permit the formation and interchange of user-generated information. Owing to the datum that mobile-social media operates on mobile gadgets, it distinguishes from outmoded social media since it integrates new aspects, for instance, the current user location (location-sensitivity) and the time interval amid sending as well as receiving texts (time-sensitivity) (Watts, 2010). Whereas traditional-social media provide a range of prospects for corporations in a comprehensive range of corporate sectors, mobile-social media utilizes the time - and location -sensitivity facets of it to take on marketing research, sales discounts or promotions, communication, and affiliation loyalty or development platforms. E-commerce businesses denote to social media as CGM (consumer-generated media). A shared thread running within all social media descriptions is a combination of social interaction and technology for the co-formation of value (Li & Bernoff, 2008). Individuals obtain information, news, education, and other facts from print and electronic media. Social media is distinctive from traditional or industrial media, for instance, newspapers, film television, since they

The development of Blues and Jazz Essay Example | Topics and Well Written Essays - 750 words

The development of Blues and Jazz - Essay Example Like jazz, the blues originated in the Deep South and had its roots in folk and popular culture, namely African American spirituals, gospel music or folk ballads (Culture and Change: Black History in America). Ironically while the proverbial Jazz Age celebrated the material excess and splendor of the years of economic boom which preceded the Great Depression, jazz and the blues had their roots in the melancholy and suffering which typified the lives of African Americans in the plantation society of the Deep South. The sadness of these musical forms, though it speaks tacitly of the pain of separation and exploitation, does not diminish its aesthetic beauty. In fact, perhaps quite paradoxically, jazz speaks of sadness even as it embraces an extremely life-affirming spirit. Perhaps the most important characteristic of jazz is its emphasis on artistic freedom. Improvisation is the most central facet of this musical genre. Improvisation which is essentially the act of creating melodies an d lyrics in the flow of a performance debunks the very idea of the normative in creative expression. Improvisation is seen in the solo performances of the best known jazz artist, Louis Armstrong as well as in the â€Å"free jazz† styles of artists such as Albert Ayler, Ornette Coleman, and John Coltrane (ibid). The trajectory of jazz and the blues is many pronged. ... are many factors which imbue jazz with not merely artistic importance but also cultural and sociopolitical importance and an analysis of these is important to this discussion. Jazz was brought to the fore in the American society shortly after the end of World War I. It celebrated, thus, freedom, happiness and the hope for peace, all things that the annihilation of war destroys. Furthermore, the Jazz Age coincided with a crucially important literary and political movement in the U.S.A.-the Harlem Renaissance. The Harlem Renaissance, predominantly an African American movement emphasized the literary and intellectual achievements of blacks and called for social and political equality for the colored people of the country. Jazz and the blues and their multifarious manifestations, formed a major part of the movement. It was celebrated in its most immediate form, music, but its beats and themes were also incorporated in dancing and literature. Above all, by celebrating the folk roots of ja zz, the movement upheld black pride and the civic equality of all Americans. In terms of its beginnings, jazz is similar to the minstrels, ballads and spirituals which have existed in every society since time immemorial. These forms are what Mikhail Bakhtin characterizes as â€Å"low† or â€Å"carnival†; they do not adhere to normative strictures of the â€Å"high† arts and seek an audience that is usually not amongst the socially and economically privileged in society (Mikhail Bakhtin). Jazz is unique by the virtue of the fact that it transcends its folk roots to enter the popular imagination of not merely the U.S.A. but many European nations as well. In fact, in the 1940s when jazz had already enjoyed a decade of dizzy popularity, jazz musicians were willing to explore in other directions

As the authors have noted (Connell 1995; Frosh, Phoenix, and Pattman 2002; Svahn 1999), ideal masculinity and stereotypical is often connected with hardness and strength. It is true that events stem from the past, but still, nearly all girls and boys would likely not be pleased to speak about their weak spots so explicitly, but would rather try to turn them into assets, into unpleasant experiences that in the end prepared them to be more independent and stronger, that is, something putting them more in conformity with masculine standards or ideals. Their nests are normally permeated with political awareness in various ways, and according to them, there is nothing not to be viewed as political. This case is a clear example of how adolescents may reflect upon matters of gender roles and identity, and make personal decisions about what they desire be like, not necessarily as boys or girls, but as individuals.

Virtual Team success Term Paper Example | Topics and Well Written Essays - 3000 words

Virtual Team success - Term Paper Example Virtual teams have objectives similar to the traditional teams, however they use different infrastructure as compared to traditional project teams. In this scenario, they perform their tasks without having the limitations of time, organizational boundaries and geographical locations associated with communication technologies. (Casey & Richardson, 2006) define virtual team as â€Å"a team whose associates make use of the technologies such as the Intranet, Intranets, Extranets and a wide variety of other networks to coordinate, communicate and collaborate with each other on work tasks and projects even if they can carry out their tasks in different geographical regions as well as away from organizations.† Thus, the virtual team is considered as contradictory from the traditional team due to the fact that its members are located across geographical regions. Additionally, virtual teams are normally implemented and managed in multilingual and multicultural surroundings, which can b e away from organizational boundaries (Casey & Richardson, 2006; Gould, 2006; DeRosa & Lepsinger, 2010). In addition, a virtual team is normally composed of people who work from home or any other location however this is not for all time the case. Virtual team associates can work in offices also. There are a numerous reasons why virtual teams are turning out to be so popular these days. The basic reason is the reality that we live in the information age, as different to the industrial age. In view of the fact that the information travels at the speed of light, and those who have access to the most modern and fastest communication and collaboration technologies are capable to send data quickly. The capability to transmit data and information at fast speeds, combined with the power of the web, has caused the formation of "virtual corporations." However, the most influential aspect of the virtual team is that it is not limited to their physical location (Exforsys Inc., 2009). This paper presents an overview of virtual teams. The basic purpose of this research is to analyze some of the impo rtant aspects that are associated with virtual teams such as working, communication, collaboration, operational model, performance enhancement aspects and so on. Why Virtual Teams are Effective? Information technology (IT) has presented a wonderful support required to deal with the advancement of new organizational forms. The concept of a virtual team is a practical example of such organizational form. A virtual team can transform and modernize the infrastructure of the place of work as well as provide the organization with extraordinary levels of power and awareness. In view of the

Home Environment and Environmental Audit Research Paper

Home Environment and Environmental Audit - Research Paper Example Finally, I would like to thank my parents for the warm influence and love which has been a source of inspiration for me for the successful completion of the work. Home environment and energy management assumes great importance in modern society as it ensures clean and hygienic surroundings and risk free environment. The environment in which people live is prone to serious epidemic diseases that can cause deadly threats to human kind. The efficient management of home surroundings protects home and its inhabitants from pollutants which contribute to the outbreak of serious illnesses to the people and make damages to homes. Similarly, energy management at home is also essential as it ensures savings of energy and money. The need for energy management is seriously felt in the present day world because of high cost and shortage of energy. Management of energy saves the money and resources not only of individual doing it, but that of the whole society and country as well. Thus, from macroeconomic point of view, energy management is indispensable for a country to sustain and develop in a situation where resource shortage is a serious issue. The two main energies used at home today are gas and electricity. It is indisputable that these two sources of energy are highly essential in human life and are dangerous at the same time. This calls for an efficient management of energies and the emissions that come out of the usage of gas and electricity. The usage of electricity emits carbon dioxide and it is likely to have adverse impact on human lives. A recent report documents that "in the UK, carbon dioxide emissions fell by 5 per cent between 1990 and 2005 despite a 43 per cent increase in GDP" (The Challenges 2006, p. 2). Turing to the impact of consumption of gas energy at home, the environment is affected by Benzene, one of the pollutants of the present day world. It is found that in the UK, 90 of the environmental pollution occur as a result of benzene (Air Pollutants 2006, Table 2, p. 34). It is also estimated that "Carbon dioxide contributed 85 per cent of the potential global warming

School Lunches Essay Example for Free

School Lunches Essay Studying at school takes much energy from millions of students all over the world. Pupils spend at school approximately 8 hours per day. Therefore many pupils have chronic illnesses, according to that 80 % of school leavers are limited in a profession choice. These problems arise due to malnutrition in school canteens. Consequently this problem worried minds of society. The aim of the report is to explore level of food which submit in Latvia and other camps of the world. â€Å"We can do a tremendous amount of good for kids across the country if we change school lunches,† says Chef Ann Cooper, the self proclaimed â€Å"renegade lunch lady†. Chef Ann Cooper is a celebrated author, chef, educator, and enduring advocate for better food for all children (Insite, 2010) It was established that one of the causes of various â€Å"school† diseases such as dental caries, stunting, disease of the gastrointenstinal tract as well as obesity occur due to the poor quality of food, which is provided by the school administrators, assert Hutton (2011). The author claims that students who chose eating lunch which was proposed by school tended to have excess weight in comparison with those students who chose taking lunch from home. Read more:  Essay About School Canteen   As a rule, students prefer eating fatty meals, for instance, burgers, french fries, chips, drinking sugary lemonades than fruits, vegetables and drinking still water. (Suddath, 2009) It means that the school administration should ban to sell fast food which contain high level of fats. Lucy Komisar is an investigative reporter and author of articles in â€Å"The New York Times† newspaper contend, that schools get food for lunches free of charge from the Agricultural Department and then some schools cook it on site but unfortunately majority schools prefer to turn these qualitative and fresh products into fried chicken nuggets, fruit pastries and others. It means that food loses the nutrition qualities after being processed. Many schools continue to exceed the standards for fat, saturated fat and sodium. (Komisar 2011) The author consider that it occurs because the school administration aspires to save money, because they not want to pay a salary to kitchen workers. Such situation occurs at present in United States of America. The problem of unhealthy food is actual not only in United States of America, but also in European countries. The statistic shows that an obesity epidemic reigns in Great Britain as well, because 25% of young people being classified as obese or overweight (Oliver 2012). Oliver (2012) believes that a school meal is vital for children`s health,  because it is one-third of a child’s daily nutritional intake. It is badly that parents of some children are too busy to cook for their children or they cook – ready meals, thus the only one possibility to eat nutritious meal for children is a school canteen, notes Oliver. Hence government should do everything to encourage children to make healthy choice, otherwise â€Å"children will continue to suffer† wrote author. Finally, compare existing situation in Latvia. The government of Latvia banned to sale in the school canteens and kindergartens unhealthy food and beverages such as: ships, coloured fizzy drinks, dye – containing chewing gums, report Leta (2006). The author state that instead of lemonades school canteen offers more healthier drinks, such as fruit or vegetable juices, water or milk. Milk and dairy products contain many valuable nutrients – calcium and protein, which should be acquired by an organism in childhood and adolescence, recommend doctors. Latvian reform of transformation school`s food, shows good results. The research shows that majority of pupils consider that the most healthier food is dairy products, soups and grain as well, ascertained the research participants. Pupils admitted that at their daily diet there are many vegetables and fruit, which helps them to restore energy (Leta, 2012). Thus the situation in Latvia is encouraging that our children will be healthy and the most cleverer in the world.

Microwave power transmission using rectenna

Microwave power transmission using rectenna   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Abstract microwave power transmission using rectenna A high efficient rectanna was design and tested at 5.8GHz frequency, which is use to power up applications. Patch antenna used with a low return low simulated in ADS. The micro-strip patch is a good practice for manufacturing physical antenna, as it will be easy to fabricate. The designed patch antenna have been employed in a 22 and 14 triangular antenna array so that the power and gain can be increased. The patch antenna captures the RF signal and then feed through 50 ohm feed line into the low pass filter and then into the rectifying circuit giving DC power. A low pass filter at 5.8 GHz was constructed. The diode used for the rectifying circuit is HSMS 2862 or HSMS 2080 schottky. A comparison analysis has been done between different designs of antenna. The results compared and best possible DC voltage was achieved in ADS simulation. ADS results achieved by simulating the designs for antennas, low pass filters and rectifying circuits were efficient. The designs were manufactured. The result generated from the physical antenna and the simulation is studied. Chapter 1 1 Introduction As the technology is growing the world is now moving toward wireless power. We can see that now days everyone prefers to use a wireless mouse or a wireless headphone. The use of batteries can make this possible but the problem is that too many batteries are being used and there has to be a way by which these applications can run wirelessly and the best thing would be if the batteries were not used. How can this be possible? This is the problem which we will try to solve in the design. The rectanna used will convert the RF power into dc signal and instead of batteries the application will have a rectanna to produce the power. Therefore we will have a true wireless system, which has no wires and no batteries. Although we have to agree that may be so power will not be produced by these rectanna but still as the technology increase, the rectanna manufacturing will also be improved. The word ‘rectenna as we know today was first introduced by Brown [4]. The basic concept of rectanna is a â€Å"rectifying antenna†. In other word an antenna which will be used for receiving RF signal and a rectifying circuit which is used to give us DC power. Personally I view rectanna as a wireless battery, which is a very cool device. Wireless power transmission (WPT) can be viewed as an electrical grid which generates power. WPT is the technology which is used for wireless transmission of power, this will be used in future for solar power satellites [4]. Let me explain the concept in detail. As the satellites are orbiting around the earth 24 hour and the satellites have the capability to convert the solar power into RF signals and then beam those RF signal to the earth. Array of antennas will be used to capture those RF signals and the rectifying circuits to convert those into DC power. If sufficient amount of array antennas are used, a lot of power can be produced. The electrical power station would be viewed as RECTANNA stations where RF signal would be converted into DC power. 1.1 History of Microwave Power Transmission Tesla was the first person who introduced the idea of wireless power transmission. Tesla was not able to produce power with the RF signal because the transmitted power got diffused in all the direction with 140 KHz radio signal [4]. The problem faced by Tesla was overcome, by the fact that higher RF frequency has greater directivity and so the power can be transmitted in a particular direction. Radar technology used in world-war 2 was also very helpful in advancing the growth of wireless power. In the early 1960s W.C. Brown used that latest technology to produce wireless power for the first time. The word â€Å"Rectanna† which we use today was first developed by W.C. Brown. He used an antenna with a rectifying circuit to produce power. The conversion was very good. Based on browns research work, where P.E. Glaser in 1968 introduced a solar power satellite [4] [3]. 1.2 Objectives The object of this thesis is to design a rectanna which will be able to receive microwave energy at 5.8 GHz and then converting that signal to DC power. This thesis will also help to provide a new ways of exploring energy resources. A secondary objective is to reduce the return losses so that maximum output can be achieved. A comparison analysis is done between series and parallel configuration of the 5.8ghz antenna. 1.2.1 Scope of thesis: Perform a good and comprehensive literature review so that all the concepts of RF electronics could be understood. Understand different antenna designs and test them to get the best possible result. Simulating and creating a functional micro-strip patch antenna design suitable for the rectenna frequency of operation of 5.8 GHz. Designing, simulating and creating the rectifier circuit. 1.3 Thesis Outline The thesis was completed in two semesters. Each a certain number task must be completed. Semester 1: Involves literature review of patch antenna, low pass filter and rectifier. The array of antenna design will also be taken under consideration and will be tested and simulated in ADS software and a prototype of 44 circular and triangular patch antenna will be build for testing purpose. Semester I Introduction to the topic Finding the research papers and resources Literature review Design proposal Simulation in ADS Operational system in ADS Prototype for testing Semester 2: The 2nd semester was utilized to make better designs and operation of antennas. Rectifying circuit will be improved as well. An application will be tested, so that the patch antenna can be used to power a small application. Semester II Tweaking of the design Making system efficient Measurements and results Comparison analysis of design Documentation and final report Chapter 2 2 Introduction To Literature Review This section outlines brief theory of micro-strip patch antennas .. The library resources were used extensively and the journals related to the power transmission using rectanna were studied in detail. The articles were used to get idea about the design as well as methods of adapting the microwave techniques. 2.1 Motivation The possibility of transferring power wirelessly can open up infinite applications. The fact that wireless application will not be powered by the batteries but instead use RF signal to generate the power is so extraordinary that everyone would want to be a part of the technology. The idea of using the solar space satellites to create power is not very new. It was first presented in 1968 by Peter E. Glaser [4] [3]. The area of wireless power is not only limited to power generation by satellites but in fact it can be used in daily electronics, such as a wireless headphone, wireless keyboard, wireless mouse and even in wireless small motors. This research will give me a glimpse of future technologies that lies ahead of us. 2.2 What I Want to Achieve At the end of this thesis I hope to have a rectenna which will convert RF signals into DC power and that DC power will be used for any selected application. 2.3 Important Points About Antenna An antenna is device which is made so that it can radiate and receive radiating power from the electromagnetic wave. There are some important points that we need to know about antenna before proceeding towards the main antenna design. 2.3.1 Antenna gain: The ratio of input power to the output power is called antenna gain. 2.3.2 Directivity: The property of antenna to radiate electromagnetic waves in a particular direction is called directivity. If the electromagnetic waves are concentrated in a particular direction then we can that antenna has good directivity. Directivity and gain are related to each other by the following formula. Gain = efficiency/Directivity. 2.3.3 Polarization: The phenomena of polarization can be understand as the orientation of electromagnetic waves at distance from the source. The polarization types have been show in the table below. 2.3.4 Impedance Matching: The energy transfer can only be possible if the antenna and the transmission lines are matched. Typically 50 ohm impedance is used for the radio. If the antenna is not match then the input power or the output power will be reflected back. As a result power will be lost and desired results will not be achieved. 2.3.5 VSWR and the Reflected power of antenna: The voltage standing wave ratio (VSWR) is a parameter, which tells us that how good the impedance match is done. A VSWR of 2:1 is considered good. Most of the antennas which are built have a VSWR of 1.5:1. Chapter 3 3 Rectenna design 3.1 Introduction to rectenna The above diagram shows a basic design of a rectanna. The antenna receives the RF signals. The signal is passed to the low pass filter by a transmission line which has an impedance of 50 ohm. The low pass filter will filter the desired frequency so that unwanted frequency does not go through the rectifying circuit. The low pass filter is also used to stop the harmonics reflected back from the diode. The rectifying circuit is used in double configuration. The double configuration is used so that maximum RF signal can be converted into DC power. Schottky diodes will be used in the rectification process as they have low voltage drop across it. The overall efficiency of the rectanna can be determined by ?= PdcPinc, Pdc is the DC output power. Pinc is the Incident RF power 3.2 Operating frequency The most common frequency used is 2.45GHz and 5.8GHz. The directivity of antenna is more at 5.8GHz. Over all a lot of applications are available at these frequencies. 3.3 Substrate Material Taconic TLX-0 was used for the physical design of the antennas. It has the following properties: H = 0.787 mm(height) T = 17  µm er= 2.45 TanD = 0.0019 Taconic TLX-0 laminate are low loss antennas.[8] 3.4 Design Specifications Chapter 4 4 Array Antennas and Design: 4.1 Introduction to Array Antennas and Design In this section is related with the antenna design in detail and the array antenna design for achieving greater power. 4.2 Micro-strip Patch Antenna The patch antenna is triangular. It has 3 layers. The bottom layer is the ground, middle is the dielectric substrate and the upper layer which is made up of copper or gold. As you can see in the figure, the 3 layer are shown. The patch antenna radiates because of the fringing fields between the ground and the patch. For good performance the thick dielectric should be used with a low dielectric constant [13]. As the design does not allow us to use a thick dielectric, otherwise the size of the antenna would be very big, so in our design a thin dielectric with high dielectric constant would be used. A micro strip antenna has some advantages and some drawback. Some of the advantages and drawbacks are given in the table. ADVANTAGES OF MICROSTRIP ANTENNA Light weight and have low volume with low profile. Fabrication cost is low, easily manufactured in big quantities. Circular and Linear polarizations can be made in them. Dual frequency and dual-polarization is also possible with this. Microwave integrated circuits can be integrated with them as well. The antenna structure can be fabricated with Feed lines and matching networks within. Figure 7 Advantages of microstrip DISADVANTAGES OF MICROSTRIP ANTENNA Bandwidth Narrow Lower gain Large losses with the feed structure. Cannot be high power handling capacity Figure 8 Disadvantages of microstrip 4.3 Feed Technique There are two types of feeding techniques Contacting: In this type feed network the RF signal is feed directly into the patch antenna. Non contacting: In this configuration electromagnetic field coupling occurs due to transfer of energy between the line of mirco-strip and the patch. 4.3.1 Micro-strip Line Feed As you can see in the figure the simplest way of having a feed line is to attach a transmission line feed with the edge of the antenna. This feed line technique is very useful as the feed line and the antenna are both on the same plane. The structure is on the same surface and area is also reduced. It has a better utility as now the antenna (with the feed line) can be place in numerous applications. The thickness of the feed line determines the impedance of the line. 4.4 ANALYSIS 4.4.1 Triangular patch antenna : As we know that lots of work have been on rectangular patch antennas and the circular patch but for my design I will be using a triangular patch so that the radiation pattern and the return losses can be studied. The size of the triangular patch is smaller than the rectangular patch, so a much more efficient design. The design formulas are, in the later sections of the report. 4.4.2 Design specifications 4.4.2.1 TRANMISSION LINE MODEL : In my design I have used the transmission line model to develop the concepts and theory behind the triangular patch antennas the equilateral triangular patch was also design using the transmission model. Resonant frequency The resonant frequency is given by [14] fr=ckmn2pEr =2c3aEr(m2 +mn+n2)1/2 1 In the above equation c is the velocity of the light in the free space. Er is the dielectric constant and K(mn) are the different modes of harmonic order. The lowest order resonant frequency given by [14] fr=2c 3aEr2 The effect of fringing field was not consideration in the above equation. The fringing field occurs at the antenna patch edge. In our case the fringing field will occur at the edge sides of the equilateral triangle. The fringing fields are depended on the physical dimension of the triangular patch and the height of the substrate material. The figure below shows the field lines of a micro-strip antenna. The maximum amount of field lines are going into the substrate and some of them are in the air. The side of a patch is increased due to the fringing field effect. The side length of a triangular patch antenna will no longer will be the same as we have to take account of the effective dielectric constant Ee. The modified equations are given below. The equation above does not take given very accurate results, as it does not consider the fringing fields produced by the antennas. The Er in equation (1) and (2) can be replaced by effective dielectric constant. The dielectric constant given by [14] Ee=Er+12+Er-14(1+12h/a)-12 3 Similarly the a can be replaced by aeff (effective). The value of the aeff (effective) given by [14] aeff=a+hEr -4 Where h is the height of the material Thus equation 2 can be replaced with the effective value of aeff and Ee giving us the final equation given by [14] fr=2c 3aeffEe5 4.4.3 Excitation technique: 4.4.3.1 Micro-strip feed: The location of feed point is determined according to dimension of the antenna. Once we have calculated the accurate dimension of the antenna then we have to connect it with a 50ohm transmission line. In my design I will be using the center fed for the patch antenna. There are two ways to do this. The first is using a quarter wave transformer and the 2nd is to use the inset model. 4.4.3.2 INSET MODEL: A triangular patch antenna was designed using the inset model. The advantage of using the inset model is that the size of the antenna reduces as compared to the quarter wave transformer design [14]. The length of the triangular patch is d. the length of transmission patch is l and the width of the transmission patch is w. the width and length of transmission patch if design do that a 50ohm impedance can be achieved. 4.4.3.3 Quarter Wavelength Transformer The quarter wave transformer is a system which is used to match the impedance. As we know that the resistance Rin of the antenna will not matched with the feed line which has a impedance of 50 ohm. A formula is used to calculate the impedance of the quarter wave transformer. 4.5 Antenna design The calculation for different antennas was designed in ADS. And the result will be shown in much detail the later sections of the report. The operating frequency is 5.8GHz. The result show in the table below is for triangular patch. 4.6 Introduction to Array theory The range of the system can be increased by array of antennas which are working together and the focus of the reception or transmission of energy also increase in a particular direction[10]. The antenna in an array can be manufactured on a micro-strip with a feed network and a power divider. There are two kinds of feed network in array antennas Single line(series feed network) Multiple feed network The series-feed network in an array of antennas is limited with a fixed beam[13]. We can see that series feed is easy to manufacture as it has the same configuration which repeats. There is a major disadvantage, any change to a single element can affect the remaining elements. The antenna elements are fed by a 1 to N (in corporate network).The power divider network has a identical path lengths to all the elements, from the feed point [13]. The phase of the element can be controlled in the corporate network with the help of phase shifters. Amplifier can be used to fix the amplitude [13]. 4.6.1 The Array Factor The array factor depends on Number of elements Element spacings Amplitude Excitation phase which is applied to each elements within the array 4.6.2 Array design As we see in the previous section that that array design is deeply affected by the element of spacing, so for 5.8 GHZ antenna the wavelength is 51.72mm, based on these factors the element spacing for 5.8GHZ antenna the element spacing should be 38.79mm. We can see that the element spacing is 0.75 % of the given wavelength. As we can see in the below figure that the quarter transformer is matched with antenna which has a impedance of 100ohm. The 100ohm line are combined together and gives a resulting impedance of 50ohm at the meeting point of the line. In the last the two 100ohm lines are combined to give a 50ohm impedance which is same for a feed line. 4.6.3 Metering of Corners In our design we are using a microstrip. So with the mircostrip antennas, the 90% angle at any corner can cause large reflection from the 90% degree angle. So a smooth edge has to be made, so that there are no reflection losses. To reduce the reflection factor the edges are metered at the corner so that there is a smooth flow of current. A equation can be used to metered the corners which is given by the equation below. 4.7 Simulation results in ADS 4.7.1 Single triangular patch 4.7.1.1 Single triangular patch : 4.7.2 Single patch with inset model: 4.7.2.1 Single patch with inset model: 4.7.3 2X2 triangular patch with inset model: 4.7.4 14 linear triangular patch: 4.7.5 Single patch with quarter wave transformer 4.7.6 22 triangular patch with quarter wave transformer CHAPTER- 5 LOW PASS FILTER 5 Low Pass Filter 5.1 Introduction to low pass filter In this chapter we will discuss the low pass filter and why is it important for the rectanna design. The techniques which will be used and calculation used to make a low pass filter. The results which are calculated by the ADS calculation will also be show in this section. 5.2 Theory behind LPF The antennas which were designed in the previous section was for 5.8Ghz but still some extra frequencies have to be filtered. The rectifying circuit also cause reflection from the first harmonics. To stop those reflection from the diode, LPF is used. LPF is extensional for the design as it can increase the power of the antenna. The LPF block the signal coming back from the diode and so the phenomena of re-radiation does not occur. The LPF is usually designed for the lower frequencies. We can use lamped component for the design but there is a problem with that. The lamped component can also cause reflection, so SMT components should be used to avoid the reflections from the inductor or the resistors. There is another good way, instead of using lumped component, the LPF can also be designed on the same transmission line by using Richard transmission. I think it would be the best thing for our design because then we would be able to make the design on the same surface. The whole design would have the same physical platform and planer surface can be achieved. There are two kinds of low pass filter which we can use in our design. Equal ripple Maximum flat 5.3 LPF Design The filter can be designed by using â€Å"Richardson method from chapter of Micro-wave engineering by david pozar[9]. We have to get the values from the table then Richard transformation is used to get the series inductors and the stub used and the shunt capacitors to shunt stubs. For Richard ?/8 at ?= ?C. Then the 2nd step would be to use the kuroda identity to series stub and shunt stubs. For the frequency of ?/8 at 2.45 GHz) and (?/8 at 5.8 GHz) we need to apply the impedance and the frequency scaling to get the accurate value. 5.3.1 Equal ripple low pass filter 5.3.2 Maximum low pass filter 5.4 Simulation results from ADS 5.5 LPF AT 5.8GHZ 5.5.1 LFP EQUAL RIPPLE (5.8GHZ) 5.5.2 LPF MAX FLAT(5.8GHZ) CHAPTER 6 6 RECTIFYING CIRCUIT FOR RECTENNA 6.1 INTRODUCTION TO RECTIFYING CIRCUIT FOR RECTENNA The final stage of the rectenna design is the rectanna which actually converts the RF signal into the DC voltage. As the diode has its own impedance so we have to match the impedance of the rectifying circuit as well. The method by which the impedance was match and the results obtained from the ADS simulation will be looked. 6.2 Single Rectifier design The single diode configuration is very easy to understand. In the positive wave of the AC signal the diode d5 is forward biased and the capacitor is being charged. When the negative wave come, the diode is reverse biased and no current crosses the diode and at that time the capacitor is providing the voltage. As the capacitor is providing the voltage we have small ripples in the simulation and in practical applications. 6.3 Single voltage quadrupler: The quadrapler provides 4 times the voltage as campared to the single rectifying circuit. The configuration is easy to fabricate and easy to understand. In the positive cycle the 2nd diode and the 4th diode is forward biased allowing the capacitor c4 and c1 to be charged. In the negative cycle the 1st and the 3rd diode are reversed biased and the capacitor c3 and c2 are being charged. The four capacitor voltages adds up before the resistor, giving us four times the voltage at the resistor. 6.4 Four 5.8 ghz with quadraupler in parallel configuration: In this design we have again used a quatrupler configuration bt this time we are using 4 sources in parallel with each other. The four parallel source were used to replicate the design, when 4 parallel antennas are used and then feeding into a single quadrupler rectifier configuration. The results are show below. 6.5 Four 5.8 ghz with four individual quadraupler rectifier in parallel configuration: The difference between the above design and this design is that, this time individual rectifier is being used with a single 5.8ghz source. The configuration is used in parallel combination. 6.6 Four 5.8 ghz with quadraupler in series configuration : In the design below a series combination was used. Four 5.8ghz source which is acting like a 5.8ghz patch antenna are configured in series conbination. The output from the source is then feed into the voltage quadrupler. The results are shown below. 6.7 HSMS 2862k Diode parameters Chapter 7 7 Conversion efficiency 7.1 Introduction to Conversion efficiency The design with different configuration was tested in ADS simulation. Now we have to move towards the physical antennas and we need to determine how we can mearsure the efficiency of a rectanna. When the antenna designs are manufactured we will tested the parrallel combination with the series combination. We will be comparing two designs. 14 array of antenna 22 array of antenna Chapter 8 8 Complete Rectenna design In this section we will see the complete rectanna design on a single surface. Which means that the low pass filter and the rectifying circuit will be on the same surface as that of the array antennas The dimension and the simulated results of all the component were shown in the above sections of the report. Chapter 9 9 CONCLUSION As we have seen that all the design of the antennas and the other component were tested at maximum in ADS and the results obtained from the ADS simulation shows that we are on the right track and we will be cable of manufacture a good efficient antenna is the next semester. The antenna will be able to convert the RF signal in DC power. The low pass filters were designed and we saw that the equal ripple filter show a much better results and so we will be using that with our design. The rectifying circuit were build and tested and a practical results show that we need a minimum of 3dbm power, so that the SMT led can be turned ON. In the future a 5.8 ghz antenna with array of 22 and 14 will be made. The simulation of 22 and 14 antenna array is already done in ADS. The designs are ready for manufacturing. 9.1 Prototype and gerber Files for Manufacturing 10 Appendix References J.O. McSpaden J.C.

Cannibalism and Feeding Habits of Dinosaurs Essays -- Exploratory Essa

Cannibalism and Feeding Habits of Dinosaurs Cannibalism is a long-standing taboo in our society; the thought of humans preying on other humans for a food source disgusts and astounds us. Though the practice is not common amongst modern day humans there is some evidence to suggest that ancient humans resorted to such measures, and a recent discovery in Madagascar attests to the possibility that some carnivorous dinosaurs fed on their own species (Perkins, 2003). Majungatholus atopus roamed the plains of northwestern Madagascar about 70 million years ago during the Late Cretaceous (Perkins, 2003; Rogers et al, 2003). The discovery of 21 tooth-marked elements originating from two Majungatholus atopus individuals suggests evidence that the dinosaur supplemented its diet by feeding on its own dead or hunting them (Rogers et al, 2003). It cannot be confirmed whether they were purely scavengers, hunters, or both. Scientists are certain that the marks are not the doing of any other predator because the teeth marks are not consistent with any other known species that lived in the area. Only one other theropod that inhabited the area during the time Majungatholus atopus did, Masiakasaurus knopfleri, had teeth and bite marks too small to have caused these markings. Two large crocodile species also shared the same ecosystem but their teeth were â€Å"too blunt and too irregularly spaced to have produced the narrow grooves found on the Majungathol us bones†(Perkins, 2003). The tooth marks on at least nine Majungatholus elements attest to intertooth spacing in the perpetrators jaw and denticle drag patterns consistent enough to make a compelling case for Majungatholus feeding on other Majungatholus (Rogers et al, 2003). The discove... ...ories of why dinosaurs went extinct abound, and as there is no theory yet to be truly confirmed as the â€Å"right one†, my theory of dinosaur cannibalism is also purely anecdotal. The discovery of the cannibalistic Majungatholus atopus in Madagascar is an important scientific find because it confirms a long-standing theory of cannibalism among certain carnivorous dinosaurs. Behavioral patterns of extinct animals are difficult to establish; however, these bones give authentication to previous unfounded beliefs about the ancient feeding practices of some dinosaurs. â€Å"A sandwich is a sandwich, but a manwich is a meal† -Jeffery Dahmer References Perkins, Sid.2003 Family Meal: Cannibal dinosaur known by its bones.

Abortion and the Privacy Amendment Essay -- Argumentative Persuasive T

Abortion and the Privacy Amendment A U.S. citizen's "right to privacy" was first discussed in an 1890 Harvard Law Review article in which two Boston lawyers, Louis Brandeis and Samuel Warren, defined it as "the right to be let alone." Since then, the right to privacy has provided the basis for a stream of revolutionary and controversial constitutional interpretations by courts across the United States, culminating in the U.S. Supreme Court's Roe v. Wade decision in 1973. Although decisions have come down in favor of a right to privacy, they are largely based on a broad and disputed interpretation of the Fourteenth Amendment. With the plethora of privacy issues that confront courts and policymakers in the current information age, the time for an amendment specifying the inalienable right to privacy is quickly approaching. Despite all the social, medical and religious undertones in the abortion debate, the Roe v. Wade opinion, written by Justice Harry Blackmun, has stood for twenty-four years on the basis that the right to choose an abortion is part of a woman's "right to personal privacy," a right that Blackmun stated is "founded in the Fourteenth Amendment's concept of personal liberty and restrictions upon state action." However, some contest that the Fourteenth Amendment does not strongly identify an inalienable right to privacy as a constitutional right. Justice Rehnquist, in the dissenting 1973 opinion, wrote, "the Court necessarily has had to find within the scope of the Fourteenth Amendment a right that was apparently completely un-known to the drafters of the Amendment." For this rea-son, some scholars, as well as members of the current Court, consider Roe v. Wade a fragile decision that ... ...s is a person. This would not be an abortion amendment. Instead, it would protect citizens from intrusions into all parts of their lives. Technology and computers have opened people's file cabinets and family photo albums, and the information revolution has just begun to reinvent the world. The privacy amendment could protect celebrities from an over-zealous press and individual citizens from governmental gene records or medical record banks. It could allow the courts to decide what information can be released for the public good, and it could allow the future issues of privacy to be solved with respect to personal rights. Without an amendment, the United States could become increasingly dependent on a questionable interpretation of the Fourteenth Amendment, leaving citizens standing naked under the beam of a roaming technology spotlight.

America’s Failure at the Bay of Pigs

Cuba was a US-controlled isand since 1898 when it won Cuba from Spain after the Spanish-American war. While itofficially controlled Cuba only until 1902, it established itself on the island with a long-term lease on Guantanamo Bay for a naval base. Up to the time before Castro was seated in power, the US ambassador to Cuba was the second most pwoerful officail after the President. (Lafeber, 19 Aril 1986, p. 537). President Truman inn March 12, 1947 called the Truman Doctrine recomended to Congress to halt the Russian aggression in Europe.â€Å"I believe that it must be the policy of the United States to support free peoples who are resisting atempted subjugation by armed minorities or by outside pressures. † (cited in Ismael, 1965, p. 3212). Regular battles with the threat of communism and in 1948, the Belrin blockade where the Russian tries to starve out the Western sector but the US responded by airlifting a tremendous amount of food and other supplies. The US assistd the Na tionalistas versus the Communista in the civil war in China which the Communists eventually won in 1949.In 1950, the US gladly responed to the call to end the Communists North America aggression towards South Korea by sending troops under Gen. Douglas McArthur. While the Korean war became inetnsely unpopular aong many Americans as casualties were heavy and the Truman administration was blamed for not foreseeing the attack. There was a general agreement nevertheless that the cuommunist leders had to be shown that the US would, if necessary, use force to stop the expansionist plans. In 1953, Dwight D. Eisenhower was elected president.Anti-cmmunist sentiment was still going strong as McCarthy continued his unproven charges â€Å"that the government payrll included communists†. Through his charges, teh Sneator speread fear and dissension throughout the countyr. In 1954, Cimmunist China threatened the islands held by the Nationalist government. The US announced that it would defen d Taiwan against any atack and pledged itself to aid any fellow Sout East Asian Trety Organizaton member in fighting communist advances. Communist influence in Latin America became more and more apparent especially in Cuba. In 1959, Fidel Castro ended the island’s totalitarian governemnt.Soon, Caro was displaying dictatorial tendencies and strong leanings towards communism. By 1960, it was evident that Cuba was trying to implant communism in other Latin American nations. (Book of Knowledge) Castro first attracted international attention and national history when he led an unsuccessful attack on the Moncada Barracks in Santiago, Cuba on July 24th 1953 hoping to overthrwo the dictatorship of then President Fulgencio Batista. Castro was pardoned in 1955 and sailed to Mexico but returned in 1956 and instigated a guerila wafare against Batista’s regime.In the early hours of 1st January 1959, Batista and the former Prime Minisster and newly–elected President Dr. Andre s Rivero Aguero fled Cuba (Telzrow, 2006). On Jan. 6th, an official note proclaiming â€Å"the sincere goodwill of the government of the United States towards the new government† was sent to Castro (Welch, 1982, p. 29). Career diplomat Philip Bonsal was then appointed as the new US Ambassador to Havana with the hope that Bonsal will be able develop good raltions with Castro replicating his sucess in Bolivia where he was able to establisg good relationships with the left-leaning incumbent adminsitration.On April 19, 1959 after a 3 ? hour meeting with Vice President Richard Nixon in Washington D. C. , Nixon was convinced that Castro was indeed a communist. Castro was determined to transform Cuba led to radical reforms and other economic changes that brought him closer to the Cuba communist party and put him on a collisison course with the Eisenhower Adminsrtration. When in early 1960, the US tried to strangle Castro with tough economic sanctions, he turned to the Soviet bloc fo r help. (Lafeber) Free lections were suspended, private business was socialized, US property was confiscated, On Oct.12, the Cuban government nationalizes 382 big businesses including manufacturers of sugar, liquor, beer, perfume, soap, textiles and milk products as well as bank. (Blight & Kornbluh, 1999, p. 161). As early as Oct. 1959, programs had been proposed by the Department of State in agreement with the CIA to support elements opposed to the Cuban government while making Castro’s downfall seem to be the result of his own mistakes. In Dec. 1959, J. C. King, the CIA’s head of its Western Hemisphere division outlines a series of covert and propaganda operations to overthrow Castro.On March 17, Preseident Eisenhower approves a CIA policy paper title â€Å"A Program of Covert Action Against the Castro Regime†. (Blight & Kornbluh, 1999, p. 159). In the History of Cuba as compiled and written by J. A. Sierra (2007, par. 14), the plan was siad to have included: 1) the creation of a responsible and unified Cuabn opposition to the Castro regime located outside of Cuba, 2) the development of a means for mass communication to the Cuban people as part of a powerful propaganda offesnive,3) the creations and development of a covert intelligence and action organization within Cuba whioch would respond to the orders and directions o the exile opposition, and 4) the development of a paramilitray force otuside of Cuba for future guerilla action. These goals were to be achieved ‘in sucg a manner as to avoid the appearance of U. S. intervention. ’ In July 1960, Soviet Prime Minister Nikita Khruschev openly declared its support for Castro by speaking of â€Å"figurative rockets that would protect Cuba from teh U. S. † to which Pres.Eisenhower announced that the US would no â€Å"tolrate the establishment of a regime dominated by international communism in the Western hemisphere. (cited in Sierra, 2007, par. 7). On Oct. 28, Amb. Bons al was permanently recalled to Washington. On Jan. 3, 1961, all diplomtic relations were broken off with Cuba. The year 1960 was also the year for the campaign period for the the presidential elections. Vice President Richard Nixon was running against SenatorJohn F. Kennedy. The Kennedy campiagn rode on the American voters anti-Castro sentiment and their restlessness towards the resolution of the Castro issue.On the eve of a candidate’s debate, Kennedy attacked Eisenhower’s Cuba policy. He called for U. S. support for the â€Å"non-Batista anti-Castro forces in exile, and in Cuba itself, who offer eventual hope for overthrowing Castro. † Stated further, â€Å"thus far these fighers for freedom have had no support from our government. † Nixon attacks Kennedy’s position on Cuba as irresponsible and reckless since he knew that CIA Director Allan Dulles himslef briefed Kennedy some months back on intelligence amtters including the training of Cuban exi les for operations against the Castro government.(Blight & Kornbluh, 1999, pp. 160-162). Meanwhile, the program for covert action was being put in place. Radio Swan goes on the air in May 1960. The programs were taped in Miami and routed throught the Swan transmitter, An airport was built in Guatemala, a cuntry whose president was beholden to the CIA-led U. S. support in overthrowing the reformist government in 1954. The Cuban exiled forces called Brigade 2506 who were being trained in Useppa Island off the coast of Florida were transferred to a camp in Guatemala.Eventually, the size of the brigade grew to about 1,500 soldiers and were called Brigade 2506. A few months later, Castro charged â€Å"that the U. S. has taken over Swan Island and has setup a very powerful broadcasting station there, â€Å" during an address to the UN General Assembly which the US refuted claiming that there is a private commercial broadcasting station in Swan Island . Foreigh Minsiter Raul Roa addresse d the UN a month later providing details on the recruitment and training of the Cuban exiles wherein he referred to them as mercenaries and counter-revolutionaries.The CIA recruits were paid USD400 per month to train and an additional USD175. 00 for their wives and more for their children. (Sierra, 2007, par. 19) NOTE: In a historic meeting of the participants of both sides in 2001, Castro himself pointedly referred to them as brigadistas. President Eisenhower approves a budget of USD13 million for the covert antCastro operation as well as the use of the Department of Defense personnel and equipment. However, it was specified that no US military personnel are to be used in combat status. 2ND PLAN The CIA changes the conception of the plan in Nov.8-9, 1960 from a guerilla infiltraion to an amphibious invasion Blight & Kornbluh, 1999, p. 162). Why? – Cuban accustaion of propaganda via Radio Swan – First attempt at droping weapons and supplies to the internal Cuban resist ance was a failure having missed the drop zone by seven miles, lands on a dam, picked up by Castro forces and the gound agent caught and shot – Young officers revolt in Guatemala due to the presence of the Cuba expeditionary force which the US helped to quell – The operation is no longer a secret as it is known all over Latin America and was being discussed in UN circles.The Joint Chief of Staff were consulted for the first time on Jan. 11th 1961. A working committee including representatives from the CIA, Defense and the JCS resulted which the Pentagon code names Operation Bumpy Road. On Jan. 28th, newly-elected President John F. Kennedy receives his first CIA briefing on the Cuban operation. The concept of the plan as outlined in the memorandum prepared by two senior CIA official in charge of the brigade, Jacob Esteline and Jack Hawkins is as follows: The initial mission of the invasion force will be to seize and defend a small area.There will be no attempt to break out of lodgment for further offensive operations unless and until there is a general uprising against the Castro regime or overt military intervention by the US forces has taken place. (Blight & Kornbluh, 1999, p. 164). The landing would be in the vicinity of the old colonial city of Trinida, Cuba in the southern coast of Cuba. This is approximately 400 km. Southeast of Havana at the foothills of Escambray mountains. The Trinidad site provided a number of options that the exile brigade could exploit during the invasion.The popiltaion of Trinidad was generally opposed to Castro and the rugged mountains outside the city provided an area into which the invasion force could retreat and establish a guerilla campaign were the landing to falter. Throughout the 1960, the growing ranks of Briagde 2560 rained throughout for the beach landing and possible mountain retreat (Wikipedia). Richard Bissell, CIA Director of Plans, assessed the plans as having â€Å"a fair chance of success – success meaning ability to survive, hold ground and attarct groing support for Cubans and get a ful-fledged civil war in which the US could then back the anti-Castro forces openly.At worst, the invaders should be able to fight their way to the Escabray and go into guerilla action. (Bight & Kornbluh, 1999, p. 164). The military plan for d-day of Macrh 5 is put back until April after examination of all possible alternatives. Why? – State Department point out grave effects on US position in Latin America – No way to disgusie US complicity However, Bissell argued for the invasion on the grounds of â€Å"disposal† problem if the mission is aborted: â€Å"brigade members will be angry, disillusioned and aggressive† (in fact a revolt did occur in late Jan.1961 among the Cuban exiles in Guatemala and almost half of the more than 500 en in camp resigned. ) (Blight & Kornbluh, 1999, p. 164). Bissell concludes that this is the last opportunity for the US to bring do wn Castro without overt US military intervention or a full embargo. National Security Adviser McGeorge Bundy recommended to institute a trade embargo first and let internal oppositon build for several months and then launch â€Å"Bissells’s battalion†. Ther Trinida plan is rejected as the President prepfers a quiet landing, prefereably at night with no basis for American military intervention.CIA presented three alternatives. The first is a modification of the Trinidad plan, the second targets an area on the northeast coast of Cuba and the thrid is an invasion at the Bay of Pigs codenamed â€Å"Opertion Zapata†. The pPresident orders modifcations of the Zapata Plan to mak it appear more like an inside, guerilla-type operation. It was modified to a night landing (instead of a dawn landing) and air drops a t first light. Kennedy questions the necessity of the air strikes, A compromise is agreed upon limited air strikes two days pror to d-day simultanoeus with a di versionary landing of 160 men in Eastern Cuba.These strikes will give the impression of being the action of Cuban pilots defecting from teh Cuban air force and thus supproting the fiction that air support for the invasion force is coming from within Cuba. Bissell also reassures Kennedy that the Cubans on the island will join in an uprising. Sen. William Fulbright, chairman of the Senate Foreign Relations describes the venture as ill-considered and predicts that it will be impossible to conceal the US hand. After polling a dozen advisers, all vote in favor of moving ahead ecept for Sec.Of State Dean Rusk who remained noncommittal. Defense Sec. Requested the JCS to reconsider the rules of engagement to ensure that the US would not become oertly engaged with Castro forces. Seven days before d-day, Esterline and Hawkins, two of the leaders of the invasion call on Bissell to tell him that they want to quit. They say that the project is out of control. Bissell asks them to stay and they d o. Three days before the invsion, â€Å"Kennedy rules outm under any condition, an intervention in Cuba by the US Armed Forces.One day before the invasion, the number of plane were reduced from 16 to 6 planes as ordered by Kennedy in order to keep it minimal. On April 16, Kennedy formally approved the landing plan. However, fearing international condemnation, Kennedy cancels the dawn air strikes until the beachhead airfiled is in the hands of the aldning force and completely operational and capale of supporting the raids. Bissel argued that the ships as well as the landings will be seriously endangered without the dawn strikes,In early morning, aboard the Blagar, CIA agent Grayston Lynch receives a message from Washington: â€Å"Castro still has operational aircraft. Expect you to be hit at dawn. Unload all troops and supplies and take ships to sea as soon as possible. † On learning that the invading troops will meet resistance in the landing area, due to failure to destroy all of the Cuban air force, the Blagar moves in close to shore and delivers gunfire support. Brigade troops commence landing at 0100 hours. Later that morning, the Houston comes under air attack and is hit.It goes aground with about 180 men on the west side of the Bay of Pigs—about five miles from the landing beach. At 9:30 AM, the freighter Rio Escondido is sunk by a direct rocket hit from a Sea Fury—with ten day's reserves of ammunition on board, as well as food, hospital equipment, and gasoline. All crew members are rescued and transferred to the Blagar. Fighting rages throughout the day, with the brigade freighters withdrawing 50 miles out to sea. That evening, President Kennedy discusses the deteriorating situation with his advisers.(Blight & Kornbluh, 1999, p. 168). On April 18, the Brigade Commander refused a call for evacuation. While at the UN on the same day, Ambassador Adlai Stevenson continued to deny that the United States had intervened militarily in Cuba . Bissell, in direct violation of Kennedy’s instructions, authorized American pilots to fly combat missions when a number of the Cuban pilots at Pueto Cabezos refused to fly. On April 19, two planes flown by U. S. pilots were shot down and the pilots killed. The invasion force were captured.About 130 were killed and 1,189 were taken prisoners. Cuba’s casualties were about 157. Mass trial were held and each was sentenced to 30 years in prison. After 20 months of negotations, most were released in echange for USD53 million in baby food and medical supplies. (Sierra, 2007). Lymann Kirkpatrick, the CIA Inspector General, issued a report that pointed to Bissell and his aide Tracy Barnes as not having firm plans for the invasion and failed to advise Kennedy that a covert action is not at all possible.Bissell rebutted by issuing a memorandum of his own and putting the blame on Kennedy’s withdrawal of the air strikes. On June 13, 1961, General Taylor, head of the Taylor Commitee composed on Gen. Maxwell taylor, Atty. General Robert Kennedy, Adm. Arleigh Burke and Dir. Gen. Of CIA Allen Dulles to investigate why the operation failed submits their report to President Kennedy: A paramilitary operation of the magnitude of Zapata could not be prepared and conducted in such a way that all U. S.support of it and connection with it could be plausibly disclaimed†¦. By about November 1960, the impossibility of running Zapata as a covert operation under CIA should have been recognized and the situation reviewed. If a reorientation of the operation had not been possible, the project should have been abandoned. (Blight & Kornbluh, 1999, p. 169). Apart from the reports of Kirkpatrick of the CIA and the Taylor Committee, and after more documents relating to the Bay of Pigs invasion surfaced and were declassified, the following can be concluded:– the CIA made decisions on mere assumptions that the people would spontaneously assist in overthrowing Cast ro (Lafeber, 1986). – they failed to see that the exiles and the supporters were the loud minority while the majority were straddling the fence in a wait-and-see attitude inasmuch as Castro’s government was still at its inception and already seemed to have eben serious about its reforms in distributing the wealth concentrated on the few during the previous regime which was openly supported by the U.S. – the United States could have lost sympathy from the locals since from 1898, they have exerted great influence over Cuba’s internal affairs seemingly to the point of meddling in order to favor American businessees and the invasion was undeniably a US-backed operation – the US did not trust its own invading force, not even telling the Cuban exiles the actual day of the invason. One aganet admitted that, â€Å"I don’t trsut any goddamn Cuban.† (Lafeber, 1986) – aside from being trapped by his own campaign statements, the ongoing co ld war forced Kennedy to take immediate if undecisive action in battling Cuba’s Castro and ultimately the USSR’s Nikita Kruschev for the Western hemisphere – there were tactical errors such as mistaking the coral reefs in the Bay of Pigs for seaweed which ran the exile craft aground and made easy targets – the US underestimated the Castro’s security and defenses.In a historic meeting in 2001 between the antagonists and the protagonists in the invasion which was held in Cuba, it was divulged that â€Å"a vast security network had been established and about 20,000 suspected dissidents were rounded up† which effectively squelched US expectations of a mass rebellion. Moreover, the Cuban air forces’ better planes were camouflaged and the ones that were destroyed by teh pre-d-day strike were decoys. (Dinges, 2001, p. 6).– the CIA strategy is rooted on another assumption that no president, Kennedy included despite his statements again st overt operations, will allow the United States to â€Å"go down in ignominous defeat† and will send in the Marines (as related by Whote House adviser Arthur Schlesinger, Jr. In Dinges, 2001). – There were no CIA broadcasts to announce the invasion (Telzrow, 2006). It would seem highly improbable that the world’s greatest superpower would be defeated by a revolutionary government barely over a year in power. However, that is exactly what Cuba did did under Fidel Castro’s leadership.On April 19, 1961 Cuba was able to repulse an invasion led by 1,400 commandos of Brigade 2506 who arrived at Playa Giron (Giron Beach) from Bahia de Cochinos (Bay of Pigs) Brigade 2506 was US-backed all the way. The planning and training was done by the CIA. They were armed and supplied by the US. It was not a failure of the men of the invasion force who fought valiantly and refused to be evacuated. Given the circumstances surrounding the invasion, it was a â€Å"perfect fai lure† as it has now been dubbed for the spectacular defeat of the US.Overall, this is mainly due to the arrogance displayed by America and has now been immortalized in the Bay of Pigs. ?
