Hyperthyroidism Research Paper Example | Topics and Well Written Essays - 1000 words

Hyperthyroidism - Research Paper Example It can be treated in a variety of ways, with the doctor deciding the best method of treatment after studying the age, history and cause of the disease of individual patients . The disease is more common in women than in men and rarely affects children below 15 years of age.It is estimated that about 1% of the US population has hyperthyroidism. It is most often seen in elderly people who are over 60 years of age in the form of thyroid nodules that are lumps in the thyroid gland. The condition is treated with anti-thyroid drugs, surgery, or radioactive iodine. People with hyperthyroidism can live normal, active lives with regular monitoring and medical care. The human endocrine system is made up of glands that secrete hormones that are released into the bloodstream and maintain the body’s metabolism.The endocrine glands are the main hormone producing glands in the human body. The thyroid gland in the neck is one of the glands of the endocrine system, the pituitary gland in the b rain is another. The pituitary gland which is about the size of a pea, is located at the base of the brain. It is often referred to as the master gland because it controls several glands in the endocrine system. ... Iodine is a very important component of the thyroid hormone. When the thyroid gland produces too much of the thyroid hormone, it results in a condition known as Hyperthyroidism commonly known as overactive thyroid. It is sometimes called thyrotoxicosis which is the technical term for too much thyroid hormone in the blood. The term hyperthyroidism refers to a group of disorders that are associated with increased levels of thyroid hormone in the blood. â€Å"Hyperthyroidism affects 2.5 million people in the United States, but could affect up to 4.5 million people because more than half of the people with thyroid disease don't know they have it. Although it occurs at all ages, hyperthyroidism is most likely to occur after the age of 15.†(Gale Encyclopedia of Alternative medicine 2005) The term hyperthyroidism is used to refer to diseases that are caused due to excessive production of the hormones produced in the thyroid gland. The thyroid gland produces two hormones - One contain ing 4 units of iodine called Thyroxin (T4) and the other called triiodothyronine (T3) which contains three units of iodine. These two hormones regulate the body's metabolic rate by helping to form protein ribonucleic acid (RNA) and increasing oxygen absorption in every cell. An increase in metabolic activity, is how cells respond to the thyroid hormone. Metabolic activity, or metabolism, refers to the processes in the body that produce energy. The chemical substances necessary for cells to grow, divide, to form new cells, and perform other vital functions are all processes included under the term metabolism . Metabolism controls the rate at which cells burn fuels from food to produce energy. Increase

Santa Fe Grill Restaurant Survey Essay Example | Topics and Well Written Essays - 1750 words

Santa Fe Grill Restaurant Survey - Essay Example The mean values for X22 and X32 are 4.82963 and 0.348148148 respectively. To determine if the two mean are significantly different with an equal variance, a t-statistical analysis is undertaken. The one tail results give a t-critical of 1.647649 while the two tails gives a t-critical result of 1.964318. However; going by the one tail, the t-critical is 1.647649 compared with a significance level of 0.00, we accept the null hypothesis that the two means are statistically significant. According to the book page 498, this analysis was supposed to compare the level of satisfaction between male and female-considering the mean. However, from the results there is no substantial support for the null hypothesis to ascertain that the two means are equal, and hence we conclude that male customers are significantly more satisfied than female customers. The mean values of X21, X22 and X23 are 4.82963, 4.464198 and 3.785185. The null hypothesis is to test if the mean of the variables are significantly different. The p-value=3.59 while the significant level ÃŽ ±=o.05; therefore we accept the null hypothesis that the mean of the variables are significantly different (p-value>0.05). That is, the mean perceptions of males between the two restaurants do not differ significantly on satisfaction or likelihood of returning. Most customers at the restaurant do not like to party as this is revealed by 14 out of 450 strongly agreed to like partying. However, it is worth noting that some customers are influenced by friends before deciding on what to take while reasonable prices also influences the customer’s decision to take a meal at the restaurant. Among the respondents, at least half agreed that attractive interior and excellent food are some of the driving factors that they consider before entering a restaurant. This is something that Santa Fe Grill Restaurant has to contend with if it wants to maximize its profits and revenues. According to the frequency

Time and Nanotechnology Essay Example for Free

Time and Nanotechnology Essay Do you believe in technology? Or do you think that all inventions of scientists are worthwhile for humanity? Of course, lots of these inventions are helpful and useful. Also, some of them have created new periods in past. They played a big role for coming modernity. However, there are some inventions that seem very effective but they have brought new problems for humanity and environment. Especially, at the beginning of an invention, people don’t realize that it will become big problem. Nowadays, people are taking notice of this kind of things. Nanotechnology is one of these inventions which are needed to be discussed from point to point. Today, there are some people who believe that nanotechnology is dangerous; however some scientists think that nanotechnology has great benefits because it helps people to invent new things for the future. Nanotechnology is a huge area which gives opportunity for other technologies to create better products. With the benefits of nanotechnology, it will be easy to develop new things. First of all, I want to explain a little bit what nanotechnology is. Nanotechnology is taking up the control of matter on a molecular scale. It deals with very little structures which is 100 times smaller. At this scale, properties of products can be changed, giving one the ability to create new things such as create more precise, cleaner, better, stronger and more durable products. For example, today, there are some kind of battery which is produced with nanotechnlogy, much more durable than before. In addition, in the future, it will be easy to invent new products and machines because nanotechnology will play vital role on manufacturing. According to Angelo (2007), â€Å"Nanotechnology promises to fundamentally change the way materials and devices will be produce in the future† (pp. 256). This can be change the future totally. Nanotechnology has contributed so much to advances in many different areas. Lots of technologies are affected from new developments in nanotechnology because these developments open a new period for others. Medicine is the most important area which is affected from nanotechnology. Today, there are some diseases which have not any treatment and cause lots of death. To illustrate, cancer is one of these diseases. But with the usage of nanotechnology in cancer treatments, scientists found a way to treat people. Also, it looks to be more developments on medicine in the future. Another important area is electronics. Like nanotechnology, electronics is very important area for new developments. Nanotechnology has contributed so much to electronics. According to Miller et al. (2004), Nanotechnology has effect on the electronic tools and systems and it is getting possible to develop on computer processing, memory and data storage and demonstration technology (pp. 24). With the usage of nanotechnology, there are lots of materials which are very small, strong and faster than before. The last important area is textile industry. New developments of nanotechnology also play vital role on this industry. Today, new textile products are more durable to heat, UV ray and chemicals because of the changing the structure of products. In addition, it seems to be more advance in the future.

Classical Theories Describing Trade Between Different Nations Economics Essay

Classical Theories Describing Trade Between Different Nations Economics Essay The following essay encompasses a review based on two of the popular Classical Theories describing the fundamental basis for trade between different nations. The foremost part comprises of a treatise about the ways in which Ricardos law of comparative advantage is superior to Smiths theory of absolute advantage. The middle part is a discussion over the gains from trade arising as a result of comparative advantage. The final part talks about ways in which a less efficient country can export anything to a second nation that is more efficient in production of all commodities. In what way was Ricardos law of comparative advantage superior to Smiths theory of absolute advantage? It is imperative to understand Ricardos law and Smiths theory in order to be able to highlight superiority of former over the later. Smiths theory of absolute advantage declares that A country benefits by producing only those products in which it has absolute advantage, or can produce using fewer resources than another country. (Cavusgil, Knight, Riesenberger, 2008 ) Adam Smith was of the view point that since one nations import is the export of another nation so it was not viable for all countries to become wealthy concurrently by following mercantilist view. He asserted that if all countries were to focus only on products in which they have absolute advantage, they could export them to other countries and in return import those products in which they do not have absolute advantage in producing. He believed that this free trade will benefit all countries simultaneously. Ricardos law of comparative advantage states that It can be beneficial for two countries to trade without barriers as long as one is more efficient at producing goods or services needed by the other. What matters is not the absolute cost of production, but rather the relative efficiency with which a country can produce the product. ( Cavusgil, et.al.2008) David Ricardo argued that international trade will benefit countries even if one nation has an absolute advantage in production of all commodoties. He believed that if a country could produce a product more efficiently than a country which was self sufficient in producing the same product but with less efficiency then it is better to import that commodity from the country producing it more efficiently. Though Smith successfully established the case for free trade, he did not develop the concept of comparative advantage. Because absolute advantage is determined by a simple comparison of labor productivities, it is possible for a nation to have absolute advantage in nothing. (www.encyclopedia.com) The above excerpt quite answers the way in which Ricardos law has an advantage over the Smiths theory. The key point of the selection is quite evident: What if a nation has absolute advantage in nothing? Does it stop importing products from other nations because it has nothing to export? This is where David Recardos law of comparative advantage is superior to Smiths theory. It is more comprehensive in terms of associating specialization with opportunity cost. Unlike Smiths theory which is completely based on absolute advantage, Ricardos law of comparative advantage generates hope for nations that are technically on the back foot by entailing that they can involve in international trade even if their labor output in all commodities is less than that of a developed country. In todays scenario, an example could be of Pakistan exporting cotton products to United States and importing military guns, tanks and missiles. (http://internationaltrade.suite101.com/) United States can produce cotton products too but relatively less efficiently than Pakistan. On the contrary, United States has a relative advantage in making military products. According to Ricardos law of comparative advantage, United States is benefitting from Pakistans efficiency in making cotton products whereas Pakistan is benefitting from United Statess efficiency in making military products. The above example justifieses the win-win situation as was proposed by Ricardo. If United States was to choose to grow cotton on its land and make its own cotton products, it could possibly have done that, less efficiently though. This signifies that if Smiths theory was implemented, Pakistan would have nothing left to trade with the United States. How do gains from trade arise with comparative advantage? Based on Ricardos law of comparative advantage, gains from trade arise in terms of increased world output for any commodities that any two countries import and export from each other. No one country wastes extra time and money producing the same product less efficiently which another country can produce more efficiently. Let us assume that Country A produces a commodity more efficiently and therefore has a relative/comparative advantage over Country B for that commodity which might be able to produce that same commodity but less efficiently. Suppose Country A exports its commodity to Country B in exchange for importing something which it cannot produce as efficiently. Both Countries A and B utilized comparative advantage to get what they wanted. Both countries gained from each others area of expertise. This assumption outlines outcome of Ricardos law of comparative advantage. Another example could be of trade between Saudi Arabia and Australia. Both nations utilize their natural advantages to gain from trade. Saudi Arabia has ample Oil which it exports to Australia. In return it imports Bauxite (finest quality of coal) from Australia. In this way, both nations are benefitting by exchanging what they have in excess with what they do not have or which may be there but more difficult to extract. Australia might be having reservoirs of Oil available deep within its Oceanic boundaries but the cost of extracting them would be too high. Labor costs are much higher in developed countries such as United States. These countries mostly hire government owned or government supported firms providing cheap skillful labor in developing countries such as China to get their task accomplished. What did they each gain from trade arising with comparative advantage? Developed countries gain: Cheap labor hence more profit. Developing countries gain: Employment. So it becomes a win-win situation. United States gets its product manufactured at a much lower cost than it would have back in United States. China gets employment. How can a nation that is less efficient than another nation in the production of all commodities export anything to the second nation? Ricardos law of comparative advantage demonstrates that a nation that is less efficient than another nation in the production of all commodities can still export to the second nation. That is because what matters is not the absolute cost of production, but rather the ratio between how easily the two countries can produce the products. (Cavusgil, et.al.2008) Ways in which Ricardos law plays its role in helping a less efficient nation export commodities to a more efficient nation have been discussed in the previous part of question. A less efficient nation can also export to the more efficient nation by implementing and incorporating competitive advantage in its international trade policies. A nation can attain competetive advantage by coming up with innovative advancements, by targeting industries for development, providing low-cost investment, reducing taxes, and by investing in emerging technologies to take up the future. Policies should be encouraging for local and foreign investments such as tax free business in Dubai. Industrial clusters should be promoted which often act as a nations export platform. Michael Porters famous Diamond Model outlines the way a country can increase its competetiveness: ( Cavusgil, Knight, Riesenberger, 2008, pp-104) Conclusion: As is evident from the above essay, Ricardos law is superior from Smiths theory because it justifies that trade is still possible between two countries even if a country does dont have absolute advantage in anything. The above arguments also prove that comparative advantage is advantageous to both the trading nations as a result of utilizing relative advantage in import and export. Besides Ricardos law of comparative advantage, competetive advantage supported by Michael Porters Diamond Model can help a less efficient nation develop industrial clusters so as to be able to export to a more efficient nation.

As part of the cell cycle, mitosis is the nuclear division of replicated chromosomes by the disconnection of the replicated chromosomes to form two genetically identical daughter nuclei. Escorted by mitosis is commonly the process of cytokinesis. The cytokinesis process entails a dividing cell splitting into two, resulting in the subdivision of the cytoplasm into two cellular suites. The process of mitosis can take place in either a haploid (23 chromosomes) or a diploid (46 chromosomes) cell. Before a cell can be ready for a mitotic division it must primarily undergo its interphase stage. Following the interphase stage several other stages come into play. These stages are prophase, prometaphase, metaphase, anaphase, and telophase. During each specific stage certain sequences of events take place that assist to the completion of the division. During interphase, cell growth, DNA replication, separation of centrioles and protein synthesis takes place. This phase is acknowledged to being the most extensive period of the cell cycle thus signifying the stage in which the cell devotes th...
