Yunkyung Eom Professor Chad Hammett English 1301 April 23, 2017 Hypertension, Cause and Prescription In my biology class I learned many Americans have hypertension. So, as one of the people living in America, I decided to research on what hypertension is and why many American have hypertension and what the prescription would be. The number of people living with hypertension (high blood pressure) is predicted to be 1.56 billion worldwide by the year 2025. In the US, around 75 million people have hypertension, with more people dying of hypertension-related cardiovascular disease than from the next three deadliest diseases combined. In 2011-2012 in the US, about a third of all people over the age of 20 years had†¦show more content†¦Many people find out about hypertension only when they suffer a heart attack or get a medical check-up done. Hypertension is a life-threatening condition characterized by high blood pressure in the arteries leading to the lungs and heart. Unlike regular hypertension or high blood pressure, hypertension occurs when the arteries in the lungs become blocked or narrow, making it harder for the heart to pump blood through them. This raises blood pressure in the lungs and causes the heart to weaken, which may eventually lead to heart failure. Hypertension is also dangerous because it can lead to strokes, heart attacks, heart failure, or kidney disease. So the goal of hypertension treatment is to lower high blood pressure and protect important organs, like the brain, heart, and kidneys from damage. The causes resulting in hypertension vary from person to person and can be extremely difficult to identify. In other words the exact causes of high blood pressure are not known, but several factors and conditions may play a role in its development, including: Smoking, Being overweight or obese, Lack of physical activity, Too much salt in the diet, Too much alcohol consumption (more than 1 to 2 drinks per day), Stress, Older age, Genetics,

What Is Causing the Decline in Honeybee Populations

Kids everywhere may revel in the fact that bees are no longer stinging them as frequently on playgrounds and in backyards, but the decline in honeybee populations in the U.S. and elsewhere signals a major environmental imbalance that could have far-reaching implications for our agricultural food supply. The Importance of Honeybees Brought here from Europe in the 1600s, honeybees have become widespread across North America and are bred commercially for their abilities to produce honey and pollinate crops—90 different farm-grown foods, including many fruits and nuts, depend on honeybees. But in recent years honeybee populations across the continent have plummeted by as much as 70 percent, and biologists are still scratching their heads as to why and what to do about the problem which they have termed â€Å"colony collapse disorder† (CCD). Chemicals May Be Killing the Honeybees Many believe that our increasing use of chemical pesticides and herbicides, which honeybees ingest during their daily pollination rounds, are largely to blame. Of particular concern is a class of pesticides called neonicotinoids. Commercial beehives are also subjected to direct chemical fumigation at regular intervals to ward off destructive mites. Genetically modified crops were once a suspect, but there is no clear evidence of a   link between them and CCD. It may be that the build-up of synthetic chemicals has reached a â€Å"tipping point,† stressing bee populations to the point of collapse. Lending credence to this theory is that organic bee colonies, where synthetic pesticides are mostly avoided, are not experiencing the same kind of catastrophic collapses, according to the non-profit Organic Consumers Association. Radiation May Push Honeybees Off Course Bee populations may also be vulnerable to other factors, such as the recent increase in atmospheric electromagnetic radiation as a result of growing numbers of cell phones and wireless communication towers. The increased radiation given off by such devices may interfere with bees’ ability to navigate. A small study at Germany’s Landau University found that bees would not return to their hives when mobile phones were placed nearby, but it is thought that the conditions in the experiment do not represent real-world exposure levels. Global Warming Partly to Blame for Honeybee Deaths? Biologists also wonder if global warming may be exaggerating the growth rates of pathogens such as the mites, viruses, and fungi that are known to take their toll on bee colonies. The unusual hot-and-cold winter weather fluctuations in recent years, also blamed on global warming, may also be wreaking havoc on bee populations accustomed to more consistent seasonal weather patterns. Scientists Still Searching for Cause of Honeybee Colony Collapse Disorder A recent gathering of leading bee biologists yielded no consensus, but most agree that a combination of factors is likely to blame. â€Å"We’re going to see a lot of money poured into this problem,† says University of Maryland entomologist Galen Dively, one of the nation’s leading bee researchers. He reports that the federal government plans an allocation of $80 million to fund research in connection with CCD. â€Å"What we’re looking for,† Dively says, â€Å"is some commonality which can lead us to a cause.† Edited by Frederic Beaudry

The And Of The Cave - 1314 Words

Reason is specifically a human trait. Using it is authorizing yourself to observe and to act accordingly to your own reflection, thus overcoming your own servitude. All men are gifted with this capacity to reason thus enabling them to be free. Indeed, this unique human logical process allows people to become autonomous, therefore permitting them to emancipate from certain constraints – by reasoning individuals can set their own rules and they can refuse a blind submission to ignorance. Plato illustrates this point with his cave allegory explained in Lecture I: Plato (Lecture I: Plato, 2015, Dr. Jung-Yeup Kim). Human beings live in a cave in which they are prisoners. In order to be set free and to leave this cave, it is primordial for them†¦show more content†¦However, although in both stories the prisoner manages to get out of the illusion, and more even if in both cases the man becomes aware of his past mistake, what permitted the escape does not borrow the same ethi cal paths: In Plato s, the attempt of helping the remaining prisoners exists, however it is doomed to failure. Among those servitudes, man is mostly familiar with appetite - the animal instinct present in human beings - then passion, which can be described as extreme feelings. As stated in Lecture 3: Daoism (Lecture 3: Daoism, 2015, Dr. Jung-Yeup Kim) Human kind is essentially an animal. However, this living being is endowed with the gift of reason. He possesses the capability to have instincts and reflexes that his reason does not always control. These unmanageable reactions are mainly performed as a survival response along to eating, sleeping and reproducing (Lecture 3: Daoism, 2015, Dr. Jung-Yeup Kim). These are the only things sought by animals. Humans are able to go beyond these basic needs and they open up to other activities including intellectual actions. Therefore, reason gives individuals the capability to act upon the natural laws that governs the world in which they live and to which individuals are not entirely subject. For example, the discovery and the use of medicine have allo wed humans to live their lives without making their survival, their biological goal, and their main one. Consequently, natural

Mercantilist and Modern Use of Tariffs free essay sample

Mercantilism held tariffs in high favor for the reduced competition and monopolies, whereas modern economists disputed this in favor of a hands-off approach of free trade. Through the centuries and schools of thought, beliefs about tariffs changed and comparisons between how Mercantilism and modern economists will be shown throughout this paper. The Mercantilism concept of high, protective, exclusionary tariffs on imports allows domestic businesses and national economies to enjoy a monopoly without foreign competition.As it is believed in Mercantilism theory, a country loud be financially stronger if they were to rid themselves of foreign competition and they are able to do that by placing high taxes on the goods that are coming into their country from others. By incurring higher taxes and making foreign goods more expensive, a domestic consumer would have an incentive to buy domestic goods since they are cheaper. Although this is how the consumer behaves, a producer would have less incentive to create high quality goods as they do not have any competition. Because they are in a monopoly, they can create sub-par products and expect them to be recessed because that is all the consumer has to decide from. Now that you have seen how the Mercantilisms high tariffs work in theory, lees look at how they have worked in history. During Mercantilism, heavy emphasis was placed on national power. That was their economic goal and their way to achieve it was through maximizing their amount of gold. This was their incentive for expeditions and war as they believed that if they could succeed in this regard, it would be impossible for their nation to suffer.In the sixteenth century, France was one of the strongest countries in Europe. During this time, they adopted policies of mercantilism by restricting imports from Spain for wool and restricting exports of gold. France became a pioneer for protectionism in the seventeenth century as they continued to restrict imports while encouraging exports. France worked to increase commerce and exports by building extensive roads to serve as trade routes. England adopted much of the same principles and was able to become a powerful trading country. They placed heavy tariffs on imports while giving incentives for exports.In an effort to hinder other countries manufacturing industries, they banned the exports f certain raw materials. While the Netherlands was the trading leader of the world until Britain later took that title, they actually did not use many Mercantilism concepts. The Dutch ruthlessly engaged in several wars in the sixteenth century to colonize other parts of the world to improve trade. They fought with France and Portugal to establish overseas trading networks. Instead of using tariff policy to regulate their own well-being, the Dutch were graced with natural geographical benefits that aided their trade supremacy.They were pioneers for overseas trade and were able to take advantage of European waterways, especially the Rhine and Amuse. They invested heavily in ships and shipbuilding and that coupled with their accessibility to waterways allowed them to connect with other nations. They also had the best accessibility to trade with Asia and were able to trade with them more than any other European country. In the middle of the seventeenth century, while other countries were in conflict, Britain saved and waited until their country had the resources to confront other European countries with more advanced mercantilism policies. By the middle of the eighteenth century, high import tariffs and exclusionary policy by the French and British began to hurt the Dutch. The British and French effectively protected their own economies through this aggressive strategy, highlighting how well the tariff policy worked. Although new investment and increases in ports in these two countries would have helped the Dutch, they were excluded from the potential profits. Dutch traders experienced the fiercest competition they had ever seen which forced them to lose their supreme position that they had worked so hard to obtain two centuries earlier.Moving on to the twentieth entry, high tariffs have been seen in modern economies. In the late uses, American automobile manufacturers were trying to get protection through tariffs from Japanese manufacturers. Chrysler, General Motors and Ford all asked for help from the government to remain profitable. The United States government agreed and reached an agreement with Japan that limited the amount of vehicles that could be imported to the US. This worked the same way as tariffs in the way that it increased demand for American made vehicles.When these protective tariffs were set in place, quality in American ears fell while firms raised prices. Without competition, they had reduced incentive to produce better vehicles. Now that you have seen how Mercantilisms theory of high tariffs has been used in the past, lets look at how modern economics free trade works internationally. Free trade occurs when two countries are able to trade goods across each others borders without intervention by the government through import taxes and tariffs or subsidies. Because there are no outside influences on supply and demand, the actual price of the good can be seen for comparison. When woo countries trade with each Other, they can experience mutual gains from specialization in which they are both better off than if they did not trade. There is also opposition to free trade though and the main critique is for protectionism and the nationalistic fears of trade hindering an economy. Now that you have seen some of the theory regarding free trade, lets look at its place through history in modern economies. The concept of free trade was first established by the pioneer of modern economics, Adam Smith.He argued that England should have unregulated foreign trade and highlighted TTS benefits, such as when France can produce a good such as wine more productively than England, whereas England can produce a good such as wine more productively, then they can trade and both countries will be better off. Each country is able to have more of each good than if they were producing both items themselves. There are also increased benefits as labor becomes more specialized. Workers become more efficient and costs are lowered while output increases. Smith criticized the Mercantilism policies which restricted the volume of trade.The Mercantilism looked at the wealth f a nation by the amount of gold that it had whereas Smith insisted that a nations wealth be defined by its flow of goods. While Mercantilism believed trade was a zero-sum game, in which one trader was a winner and one was a loser and that all goods in the world were at a fixed amount, Smith showed how both nations are actually better off because of trade and by doing so, raise the quantity of goods in the world. Problems with free trade can be shown throughout history in the twentieth century. At the start of the 19005, the Aquas per capita income was growing on average 1. Per year and Western Europe was growing at 1. 3% a year while utilizing free trade (Change, p. 27). During the same time, Latin American countries had some of the highest tariffs in the world yet were growing at a similar rate. Later in the 1 sass and 1 sass, while developing Latin American countries were using tariffs and protectionism, they were growing at roughly 3. 0% a year. Throughout the 1 sass when they adopted free trade policy, their growth fell to almost one third of that. While growth slowed down significantly, income inequality rose. One of the main criticisms to free trade s the way in which it spreads the gap between rich and poor. Free trade generally does not make poor people rich but rather makes them poorer. The tariff policies of the Mercantilism and the modern economists could not be any more opposite. While Mercantilism encourage high protecting tariffs on imports, modern economists encourage free trade. Throughout history, both theories have been implemented to a countrys convenience and that can be seen throughout history. Although free trade is a modern concept, the Mercantilism concept of protectionism is still often seen today.

Royal Aircraft Factory SE5 in World War I

Royal Aircraft Factory SE5 in World War I One of the most successful aircraft used by the British in World War I (1814-1918), the Royal Aircraft Factory S.E.5 entered service in early 1917. A reliable, stable gun platform, the type soon became the favored aircraft of many notable British aces. The S.E.5a remained in use through the end of the conflict and was retained by some air forces into the 1920s. Design In 1916, the Royal Flying Corps issued a call to the British aircraft industry to produce a fighter that was superior in all respects to any aircraft currently in use by the enemy. Answering this request were the Royal Aircraft Factory at Farnborough and Sopwith Aviation. While discussions began at Sopwith which led to the legendary Camel, R.A.F.s Henry P. Folland, John Kenworthy, and Major Frank W. Goodden began working on a design of their own. Dubbed the Scout Experimental 5, the new design utilized a new water-cooled 150-hp Hispano-Suiza engine. In devising the rest of the aircraft, the team at Farnborough crafted a tough, square-rigged, single seat fighter capable of enduring high speeds during dives. Increased durability was achieved through the use of a narrow, wire braced, box-girder fuselage which improved pilot vision while also ensuring a higher rate of survivability in crashes. The new type was initially powered by a  Hispano-Suiza 150 HP V8 engine. Construction of three prototypes began in the fall of 1916, and one flew for the first time on November 22. During testing, two of the three prototypes crashed, the first killing Major Goodden on January 28, 1917. Development As the aircraft was refined, it proved to possess high speed and maneuverability, but also had excellent lateral control at lower speeds due to its square wingtips. As with previous R.A.F. designed aircraft, such as the B.E. 2, F.E. 2, and R.E. 8, the S.E. 5 was inherently stable making it an ideal gun platform. To arm the aircraft, the designers mounted a synchronized Vickers machine gun to fire through the propeller. This was partnered with a top wing-mounted Lewis gun which was attached with a Foster mounting. The use of the Foster mount permitted pilots to attack enemies from below by angling the Lewis gun upwards and simplified the process of reloading and clearing jams from the gun.

(7.7 mm) Lewis gun4x 18 kg Cooper bombs Operational History The S.E.5 began service with No. 56 Squadron in March 1917, and deployed to France the following month. Arriving during Bloody April, a month that saw Manfred von Richthofen claim 21 kills himself, the S.E.5 was one of the aircraft that aided in reclaiming the skies from the Germans. During its early career, pilots found that the S.E.5 was under-powered and voiced their complaints. Famed ace Albert Ball stated that the S.E.5 has turned out a dud. Quickly moving to address this issue, R.A.F. rolled out the S.E.5a in June 1917. Possessing a 200-hp Hispano-Suiza engine, the S.E.5a became the standard version of the aircraft with 5,265 produced. The improved version of the aircraft became a favorite of British pilots as it provided excellent high-altitude performance, good visibility, and was much easier to fly than the Sopwith Camel. Despite this, production of the S.E.5a lagged behind that of the Camel due to production difficulties with the Hispano-Suiza engine. These were not resolved until the introduction of the 200-hp Wolseley Viper (a high-compression version of the Hispano-Suiza) engine in late 1917. As a result, many squadrons slated to receive the new aircraft were forced to soldier on with older types. A Favorite of the Aces Large numbers of the S.E.5a did not reach the front until early 1918. At full deployment, the aircraft equipped 21 British and 2 American squadrons. The S.E.5a was the aircraft of choice of several famed aces such as Albert Ball, Billy Bishop, Edward Mannock, and James McCudden. Speaking of the S.E.5as impressive speed, McCudden noted that  It was very fine to be in a machine that was faster than the Huns, and to know that one could run away just as things got too hot. Serving until the end of the war, it was superior to the German Albatros series of fighters and was one of the few Allied aircraft that was not outclassed by the new Fokker D.VII in May 1918. Other Uses With the end of the war that fall, some S.E.5as were briefly retained by the Royal Air Force while the type continued to be used by Australia and Canada into the 1920s. Others found second lives in the commercial sector. In the 1920s and 1930s, Major Jack Savage retained a group of S.E.5as which were used to pioneer the concept of skywriting.   Others were modified and improved for use in air racing during the 1920s. Variants Production: During World War I, the S.E.5 was produced by Austin Motors (1,650), Air Navigation and Engineering Company (560), Martinsyde (258), the Royal Aircraft Factory (200), Vickers (2,164) and Wolseley Motor Company (431). All told, 5,265 S.E.5s were built, with all but 77 in the S.E.5a configuration. A contract for 1,000 S.E.5as was issued to the Curtiss Aeroplane and Motor Company in the United States, however only one was completed before the end of hostilities. As the conflict progressed, R.A.F. continued development of the type and unveiled the S.E.5b in April 1918.   The variant possessed a streamlined nose and spinner on the propeller as well as a retractable radiator. Other alterations included the use of single bay wings of unequal cord and span and a more streamlined fuselage. Retaining the armament of the S.E.5a, the new variant did not show significantly improved performance over the S.E.5a and was not selected for production. Testing later found that drag caused by the large upper wing offset the gains made by the sleeker fuselage.
