Kale in Kenya- Ag Issue 2012 Essay
Jonathan King Ag 101 September 16, 2012 Current Issues in Horticulture- Kale in Kenya I am going to go into the Horticultural field and one of the issues facing horticulture today is solving world hunger. Kenya is a nation that mostly lives in poverty, The United States and other countries are trying to help the Kenyan poverty problem by researching different food that can grow there along with trying to improve the food that they already have. A big crop in Kenya is kale because it costs so little to produce and the name sakuma wiki the Kenyan name for kale loosely translated means that it can sustain people throughout the week due to its extreme affordability, particularly for those who earn a dollar and below a day. The kale in Kenya is poor quality and it yields easily to diseases like black rot and leaf spot. Through a collaborative research project investigating the poor quality of kale seeds in parts of Kenya a team found that the best kale plants in Kenya originate from Kinale, a forested region north of Nairobi on the edge of the rift valley. The plants were then took to the Kenya Agricultural Research Institute and propagated to obtain clean, disease-free seed. Five lines of kale were developed and two of them did very well once the seed was tested in different parts. The propagated seed flowered later thus making the crop produce longer and had a better color with a sweeter flavored leaf. By using Horticulture the problem of hunger in Kenya is being addressed by diversifying kale to improve food and nutrition and to improve the economy by making a better plant that people would want to buy and eat.
Returning to a Place Special to You Essay
Have you ever returned to place and asked yourself ââ¬Å"Boy I miss those daysâ⬠! We all return to a place that holds many memoires, good or bad. For every person, some places hold great importance in their lives. A special place that is really important to me is my home country, Somalia. Somalia, most notably, Kismayo, is my birthplace and a place that I hold dearly in my heart. So many childhood memories of me and my family occurred in kismayo. All of my brothers, including myself, were all born in Kismayo. My mother and father met and married in the same neighborhood we live in. Family is of major significance to me, and living near many uncles, aunts, and cousins was a great experience. Returning to my birthplace was always a dream of mine. As a child, returning to my birthplace was all I thought about. I left Kismayo at the tender age of 10. A civil war broke out in Somalia in 1991, three years before my birth. The war destroyed and demoralized many families in Somalia. My family was fortunate enough to escape unscathed during this horrible and gruesome civil war. My mom and dad, along with my brothers, relocated to Kenya in exile, hoping one day to return to the place we knew before the civil war. My family returned mid-1994, and find life in kismayo very challenging. My mother gave birth to me during this year. I remember the stories my mother use to tell me about our return to Somalia and the troubles and hardships we faced upon our return. Reminiscing about my childhood, I remember the neighborhood we lived in and the daily activities I took part in. We lived in a small two room house, which at the time was large enough for are family. We lived near many of our relatives and we visited each other every day. Family is a big part of the Somali culture, and living near one another ensured a close bond with one another. Religion is perhaps the biggest value in Somali culture. I remember running up the dusty hills along with my father and brothers to perform prayer at the local mosque. We would take the same path to the mosque five times a day to perform the five mandatory prayers. Another significant value I loved was language. Every Somali shared the same language, but there are some minor regional differences. I remember enjoying the comfort of my friends and cousins after school; we would often joke with one another. We walked up hills and dirt roads for 40 minutes to school, which was an old brick house. We were taught English and math, and most of the time was devoted to religious studies. Food is another value in our culture, the common meal in our household was oatmeal and rice. I remember eating those two meals nearly every day, which at the time was a luxury because of the state of the country. During our leisure time, we would often play soccer in a dirt field, which was better than nothing. Even though we lived in poverty, our homeland was very important to us and it was all we ever knew. Everything changed once we moved to the United States during the summer of 2003. As an adult, I have lived in the United States for nearly 9 years. We came to Minnesota from the advice of our Uncle, who traveled here alone to settle down and eventually take us in. Coming to the United States was a big technological and cultural shock. The technology all around was advanced and we never seen such a sight. The buildings were humungous and exquisite, vehicles of all kinds roamed the streets like a herd of animals, and so many different ethnicities and cultures integrated into one country. The luxury of electricity to light your house, clean running water from your sink, and eating foods other than rice and oatmeal was surreal. Eventually, my family and I settled in and after approximately 10 years I returned to my homeland. Returning was a special and troubling moment. The neighborhood we once lived in has not changed since the war. Most of Somalia is still underdeveloped and many live in extreme poverty. We once lived in these conditions and my mother always reminds us of where we came from and the conditions we once lived in. Many of my family members relocated to the United States, but some stayed preserving the way of life the always knew. It was rewarding seeing them after so many years; I left a child and returned as a man. Almost nothing changed and I was somewhat elated to see my homeland, and saddened by the lack of progress made to better the lives of the ones living in poverty. In the end, returning to my homeland taught me a life lesson. Even though it was some time ago, I fondly remember the conditions we lived in and it has made me more appreciative for what I have today. Aside from the difficult moments, Iââ¬â¢ve many extraordinary childhood memories from my childhood. Returning to my homeland fulfilled a lifelong dream of mine. I will always look back at those memories with great pride and joy.

Import Substitution vs. Export Promotion
Import Substitution vs. Export Promotion Econ 240 Term Paper Group (19) Members: Amjad Hussain (13020031) Awais Javed (13020529) Fahd Mukaddam (13020407) Haider Shah (13020528) Hassan Jamil (13020023) Muhammad Bilal Ayub (13020413) Words (using page 2): 371*7 = 2597 IS vs. EP 2 How do the strategies of international trade affect growth? Why at times countries adopted different strategies of international trade? How does Import Substitution Industrialization weigh against Export Promotion as a trade strategy?How does the empirical evidence help us understand this? Trade strategies are classified into two broad strategies, outward-looking development policies and inward-looking development policies. Outward-looking development policies encourage free trade and free movement of the factors of production. While inward-oriented development policies encourage greater self-reliance and restricted trade. Within these two broad approaches lies the debate between Import Substitution (protectio nism) and Export Promotion (free trade).Import substitution (IS) is a well tested way to industrialization which has been followed by most of the currently developed and industrialized countries. Alexander Hamiltonââ¬â¢s ââ¬Å"Report on Manufacturesâ⬠(1791) argued in favor of tariffs to protect American manufacturers from inexpensive imports from Britain. In the mid 19th century, Germany, Russia and Japan also practiced protectionism to develop their domestic industries. After the great depression of 1930ââ¬â¢s, LDCs particularly Latin American and some Asian economies started practicing ISI and in 1960ââ¬â¢s IS became a dominant strategy for development.However in the next decade, when industries protected through import substitution failed to achieve targeted productive and allocative efficiencies, countries switched to export promotion strategies. Hong Kong, South Korea, Taiwan and Singapore were among the first to adopt the export promotion strategy. Later, Chile , Thailand and Turkey also joined in. Over the years, the stance of countries has shifted from protectionism to free trade and globalization. So we will begin our paper by analyzing the arguments in favor and against ISI policies.Then we will discuss the benefits and drawbacks faced by the countries that switched to the export promotion strategy. The paper also explains the reasons for this transition. Finally, it concludes by giving empirical evidence of the real world regarding the effects of these strategies. It has always been in the vested interest of the economies to protect countryââ¬â¢s large and strategic markets from foreign competition so that the local industry not only becomes self sufficient but also is in a position to induce industrialization led economic growth.In order to accomplish such goals, trends have shown (as mentioned above) countriesââ¬â¢ increased dependence on Import IS vs. EP 3 substitution policies. Government plays a vital role in the implementa tion of these policies by imposing tariffs and quotas or altering the exchange rate and interest rate, using macroeconomic policies, to shield its local industries from the competitive foreign producers. Simultaneously, the foreign direct investments (FDIs) are expected to fill the gaps in technology and technical skills between the domestic and foreign industry.The introduction of IS policy can be attributed to the Infant Industry Argument (Import Substitution In General Equilibrium can be used to demonstrate that how the IS works in infant industry) 1, which favors the protection of domestic industry from international competition. The aim is to remove distortions between the out-dated locally produced goods and the industrialized high quality imports of similar products. Policies which governments adopt includes introduction of tariffs 2; discouraging cheaper import and at the same time encouraging production of the same goods domestically.Mostly consumer goods are produced under this strategy which ensures that the country is capable of meeting its basic necessities. Moreover, these types of goods require considerably less advanced technology, making the policy easier to adopt. Aristotle has said ââ¬Å"What we have to learn to do, we learn by doingâ⬠; import protection is the best way to initiate this learning process because the economy is now producing goods that it previously imported ââ¬â a process of development and learning by doing sets up. The economy can then move towards higher efficiency.This eventually improves the balance of payments as fewer consumer goods are now imported. It is essential that the learning process is followed by accumulation of capital. This requires the manipulation in Interest rates so as to encourage savings, and these savings can then be invested back in the protected industry. There are some macroeconomic gains associated with this policy, including reduced unemployment and increased tax revenue for the govern ment; increased local production is expected to generate job opportunities and at the same time, tariff on imports become a source of income for the government. See Appendix 1. 4. 1 & 1. 4. 2 See Appendix 1. 2 2 IS vs. EP 4 However, the IS policies have been criticized by economists for various reasons. According to them, the protection provided to the industries makes the industries inefficient because the firms start to rely on the provision of subsidies. They have no incentive to cut down costs to achieve minimum efficient scale of production and to increase productivity. Bhagwati in ââ¬Å"Import substitution ââ¬â a survey of policy issuesâ⬠said that, ââ¬Å"â⬠¦such sheltered monopoly positions in import substituting industries are the prime cause of low productivityâ⬠.Also, the government protection to infant industries is for a limited time period, in which most industries that lurk behind the wall of tariffs never grow up. In import substitution, main focus is on the consumer goods, and therefore the prospects of economic growth are relatively short-lived. For countries to achieve long term economic growth, structural shifts are required towards the production of capital-intensive goods.However according to Jaleel Ahmad, the protection requires normally zero or low tariff on import of capital goods, hence discouraging development of forward linkages ââ¬â manufacturing of the capital goods by local industries. Also for Import Substitution to be successful, according to Hirschman, forward and backward linkages need to be well-developed for the industries. This shows that for a country to have a manufacturing sector free from international dependence, it will need to develop other industries in consumer durables, non-durables, intermediate and capital goods.Another argument against ISI strategies is that it leads to the worsening of Balance Of Payments (BOP) due to the overvaluation of exchange rate, causing the prices of exports to rise but at the same time lowering the prices of imports. As a consequence, producers of exportable goods become less competitive in world market, causing a negative impact on the BOP. Keeping in mind the undesirable impacts of IS policies, economists felt the need to revise the trade strategies.Trade theorists therefore attempted to elucidate as to why nations engage in international trade, what combination of goods and services they trade, and how firms and consumers gain or lose from trade. It was observed that numerous international trade models rely primarily on the theory of Comparative Advantage (Appendix 1. 1), which describes trade patterns under assumptions of static conditions that hold the factors of production in fixed supply (Perkins). Theory of comparative advantage principally asserts that every country irrespective of its size can benefit from trade. Trade driven through exports of goods in which the country has aIS vs. EP 5 comparative advantage, benefits the count ry the most. Therefore an export promotion trade strategy involving goods that require raw material, that are abundant in supply, will allow a country to grow more rapidly as stated by the Hecksher-Ohlin model. Proponents of EP mainly argue that free trade utilizes previously unused resources such as land and labor, creates a vent for surplus of unused resources and allows a country to operate on its Production Possibility Frontier (PPF). In contrast, before the opening up of the economy, the market is constrained to the domestic consumers only.Once a country engages in free trade it acquires the opportunity to earn a global market share, thus earning higher revenues. As the market of local industries expands, demand for labor increases which raises the employment level in the country. This increase in exports stimulates domestic investment (an injection in the circular flow of the income of the country) which gives a multiplied effect on the Gross Domestic Product (GDP) of the econ omy. Furthermore, the enhanced exports will lead to a greater demand of domestic currency in the exchange market leading to currencyââ¬â¢s appreciation (given the floating exchange rate mechanism).According to the Marshall Lerner condition, which states that the sum of price IS vs. EP 6 elasticity of demand of exports and imports is lesser than 1 in short run, a currency appreciation will lead to an increase in the Balance Of Trade (BOT). 3 This relationship of BOT and time is shown through J-curve. An additional argument presented by the trade optimists states that the foreign exchange earned by selling different goods and services will relax the constraints of availability of financial capital or in other words, will fill the foreign exchange gap.This also helps in relieving the pressure on foreign exchange reserves built by the import of heavy machinery and capital goods. A further extension of export promotion policy is the process of export development. It involves innovatio n (of new export products) and penetration into new markets. Learning process is instituted and hence increased productivity is observed. This initiates a process of transfer of technology and foreign investment from developed countries, helping the industry to become efficient and gain the economies of scale through mass production ââ¬â lowering costs and increasing profits.The increased profits of the industry promote higher savings and as the Harrod-Domar Model suggests, an increase in savings will lead to an increase in the growth rate of the economy. The Export promotion strategy is not free of criticisms as one might expect. The leading criticism of opponents of export promotion strategy is the sluggish growth in the demand of the primary goods. As developing country relies mainly on the export of primary goods, the sluggish growth enhances the volatility in the earnings of the economy. The Prebisch Singer Hypothesis explains this phenomenon in terms of income elasticity a nd price elasticity of demand.The thesis postulates that the price elasticity and income elasticity of primary goods are both inelastic i. e. less than 1. As the national income of the developed countries increases, the demand for the primary goods does not increase proportionately. This is also stated by Engelââ¬â¢s Law. A decrease in the prices of the exports will not lead the quantity traded to increase by the same percentage, thus resulting in fall of the exports revenue. This fall in exports revenue leads to a deterioration of Terms of Trade (TOT) of the country.Other factors that explain the slow growth in primary goods exports include the development of synthetic substitutes and protectionist measures taken 3 See Appendix 1. 3 IS vs. EP 7 by the developed countries. The population growth of developed countries being at replacement level translates into a stagnant demand for primary exports. Empirical evidence shows that heavy reliance on the export of the primary product m ay actually result in a phenomenon known as the Dutch disease; a country rich in natural resources actually suffers from slower growth as a result of that rich endowment.This is one of the often repeated facts of history when criticizing the strategy of export promotion. It was mentioned earlier that an appreciation in a countryââ¬â¢s currency will lead to an increase in BOT, but this will only remain true for the short run. In long-run the sum of elasticity of demands of exports and imports becomes greater than 1 which consequently causes a fall in the net exports. Therefore the aforementioned argument is valid in the short-run only as in long-run it balances out its own effect on BOT 4 as shown below with the aid of diagram.In addition to the criticism mentioned earlier, Export Promotion strategy may lead to higher budget deficit. It is a usual practice of the governments to subsidize the exporting industries. These subsidies will be financed either by an increase in taxes or b y reducing the expenditure on public and merit goods such as health, education, infrastructure, national defense and other social services. Due to this practice, the development side of the country is often sidelined or overlooked.Example of China can be the best evidence for our claims about Export Promotion here. China was a closed economy until the 1970s. Nicholas R. Lardy in his article, Trade liberalization and 4 See Appendix 1. 3 IS vs. EP 8 its role in Chinese economic growth, states that around 1970s, Chinaââ¬â¢s export goods had no comparative advantage and at the same time, high level of control on imports was also imposed. Hence quoting from the article, ââ¬Å"Chinaââ¬â¢s share of world trade dropped markedly, from 1. 5 percent in 1953 to only 0. 6 percent in 1977â⬠.However, during the 1980s the process of trade liberalization began and by the time china entered WTO in 2001, her structure of trade policy was completely changed. China fully realized the signifi cance of the comparative advantage principle and concentrated on export of goods that were labor intensive in production, as the article states that ââ¬Å"Chinaââ¬â¢s fastest growing exports have been labor-intensive manufacturersââ¬â textiles, apparel, footwear, and toys. Between 1980 and 1998, export of these items rose more than ten-folds, from $4. 3 billion to $53. 5 billionâ⬠.Due to the trade liberalization, China experienced high rates of economic growth. Empirical evidence strongly suggests that pragmatism and eclecticism rules over any other single purpose approaches to trade. Thinking just in terms of an all out import substitution or an export promotion strategy can pose as an impediment to oneââ¬â¢s clear understanding of the relationship between these strategies and growth. In future it would be better to avoid labels and to construct strategies from the components of either of these trade policies that seemed to have worked.Import substitution with its d ivorce of production decisions from market conditions seems to have lost its modern day relevance. In contrast, export promotion with its orientation towards world markets appears to be in line with the new phenomenon that is globalization. No single optimal prescription in terms of trade policy can be devised for the countries at large due to the dynamism of international trade. No strategy can be concluded as the best strategy for a country but what can be said is its relevance to a country at a point in time.Although empirical evidence shows that export promotion has helped countries like China to grow rapidly and improve its trade positions but we can also find other countries which developed after adopting import substitution policies like Latin American countries. This suggests that country have to adopt a trade strategy which is most compatible for their country at that time so that they can achieve maximum gains from trade. IS vs. EP 9 Appendix 1. 1 Comparative Advantage The ory: The concept of comparative advantage, attributed to David Ricardo, refers to the ability of a country to produce at a lower opportunity cost.It is the ability to produce the most efficient product as compared to other countries. It is best explained by a two-good, two country framework where countries differ in particular factor productivity or factor endowments. This theory explains that it is welfare enhancing for both countries to specialize in one good and import the other. The conclusion drawn from this theory is that each country gain by specializing in the good where it has comparative advantage and trading that good for other. 1. 2 Trade protectionism and Tariffs:Government impose trade restrictions in form of tariff in which it collects tax on goods imported by the people, thus discouraging the people to import goods and encouraging the local industries to produce good quality substitute goods. Introduction of tariff increases the world price, which reduces the amount of imports and increases the amount of locally consumed products. IS vs. EP 10 1. 3 Inverted J-curve for revaluation of currency: The inverted J-curve refers to the trend of a countryââ¬â¢s trade balance following a revaluation or appreciation of the currency.A revalued currency means that exports are more expensive for the foreign countries, but as in the short run demand for the more expensive exports remain price inelastic so the quantity demanded for exports remains same although foreigners are paying higher prices. This leads to the improvement of balance of trade. Over the long term, as the foreign consumers are able to switch to the other goods, the quantity demanded for exports becomes price elastic so reduction in the export volume and hence export revenues.This leads to the deterioration of balance of trade and the gains in the short run are off-set by the losses in the long run. In case of devaluation of currency, there are opposite affects. IS vs. EP 11 1. 4 Infant In dustry Argument(ISI in general equilibrium) : IS vs. EP 12 From diagram 1. 4. 1 it can be seen that before the imposition of tariff the country was producing at point A while consuming C amount of goods under world terms of trade (favorable to its export).But after the imposition of tariff, production moves towards point B where more of the importable and less of exportable goods are being produced. Assuming that this does not affect the world prices, trade will take place at same TOT. So the new consumption is indicated by point E along the line BD (parallel to line representing world TOT). Initially, by practicing ISI polices, both consumers and trade welfare has fallen due to lower consumption and fewer imports and exports (BE

Hospitality Property Operations - Assignment Example However, in reality, the previous stock is not fully utilized and wasted awfully and there is the overstock of supplies also been observed in the hotel of which some is spoiled as well. In order to maintain cleanliness and other satisfaction is driven parameters for the customers, the storeroom remains open all the time and everyone has the access to it. There is no proper placement of supply items in the storeroom rather there is a mess of supplies everywhere even in the telephone room. The supplies are not rightly used by the housekeeping staff like shampoos are used for cleaning the bathtub and furniture polish is used over Formica which though seems chemically effective but not the right way thus resulting in increased cost. Another issue is that things are not fully used that contributes to additional costs like everyday soap and shampoo is added to every washroom even previous is still there. Garbage bags of large size are often used that are half filled and thrown away despite using the smaller one to optimize their usage. The management structure needs to be autocratic and hierarchic to mold the behavior of the staff and to keep the check on them while using the supplies. A position may be created and the personnel may be dedicated full time for the purpose. There must be someone responsible for the storeroom and only limited access be provided to the staff. Another issue is that things are not fully used that contributes to additional costs like everyday soap and shampoo is added to every washroom even previous is still there. Garbage bags of large size are often used that are half filled and thrown away despite using the smaller one to optimize their usage.

Outsourcing is either harmful or beneficial for American economic Essay
Outsourcing is either harmful or beneficial for American economic - Essay Example This activity assists companies in lowering their costs as the cost of production in US is quite high due to high cost of labor. With the economy development, more and more U.S companies would rather to choose outsourcing than the local service. To a certain extent, it is acceptable for America and American companies to be dependant on the labor of other countries. The activity of outsourcing of jobs conducted by US companies is not only beneficial for them, it is even beneficial for other nations because in these nations, there are low amount of jobs and the amount of salary they are paid is even low. Because its lower cost can help the U.S companies develop and can save the money for local customers. Also with more working positions are moving out of the country, there will create higher income jobs for local citizens. The several benefits associated with outsourcing of jobs include higher level of creativity in production, low cost of production, higher quality of service and incr eased number of jobs and wages for the workers of other nations. Outsourcing is a term used to refer to the act of obtaining goods and services from suppliers that are not located in nations that produce those goods and services. Murray Weidenbaum, a very famous economist and ex-chairman of President Reganââ¬â¢s Council of Economic Advisers, once announced that companies located throughout the US outsource their economic activities for several reasons. He feels that reasons for outsourcing include entrance into international markets, decrease the production cost, and to gain a competitive advantage while they compete in the global markets. The main benefit that a business within U.S obtains from outsourcing is the low cost of production as the product is produced at much lower cost in other nations as compared to the same product produced in the U.S. The U.S is importing raw materials from foreign nations, and the transfer of raw materials to the destination where they are used t o produce goods may increase the cost of production. If U.S manufacturers open their production line in areas where they obtain their resources, they no longer have to worry about the cost of raw materials transportation, and can direct deliver their products from the industry. It will become more profitable for businesses. For example, if in U.S organizations are importing raw materials from China and producing goods in the U.S. They not only have to pay the cost of the shipment fee but also need to afford the high wages in the state. If the company decide to move the manufactory into China, the wages over there are much cheaper than the U.S and set China as a delivery center, and the company doesnââ¬â¢t need to pay for the raw material transportation fee and only needs to pay the shipment fee of production sale which the company always have to pay either they located the manufactory in China or U.S. With this decision making, the company can save lots of money from the labor an d transportation fee, it can definitely help company to use the rest of money to expand the market and develop the company. Also once the company less their cost on producing the product, they would also cut down the price attract the consumers to make more sales revenue. Therefore the US companies are not the only one benefiting from outsourcing, even the consumer side is positively

Modern Literature 1 Essay Example | Topics and Well Written Essays - 500 words
Modern Literature 1 - Essay Example A careful analysis of both The Heart of Darkness and Things Fall Apart evidences that Conrad and Achebe differ in the manner in which they both write about the colonizing Europeans and the native Africans. It is important to note that Achebe was an African, while Conrad was Polish and did actually not learn English until in his twenties. The very initial difference in the two stories can be derived form a careful interpretation of their titles. In Chinuaââ¬â¢s Things fall apart, he elaborates on the manner in which Europeans came and destroyed the then peaceful systems of African traditions and resulted to everything literary falling apart. In The Heart of Darkness on the other hand, Conrad exposes how the African continent can be described as a dark continent as far as development and civilization are concerned. Characters are fundamental vehicles that writers employ in conveying their meaning. Another significant difference in these two stories is evidenced through the characters. Marlow, the main character in The Heart of Darkness, travels to the central station from the outer station and encounters scenes of brutality and cruelty against the Africans. Marlowââ¬â¢s adventures portray the hypocrisy in the rhetoric employed to justify imperialism. The men working in the company describe their actions as trade and their ill treatment against Africans as part of civilization. Kurtz, another character in this story, agrees that he does not trade, but takes ivory by force. In his own words, his treatment to the Africans is extermination and suppression (56). In Things Fall Apart, on the other hand, the author describes the Native Africans with intense praise. Okonkwo, the main character, is described as a hard-working and a determined man. He achieves a lot of social and financial success th rough his hard work and is viewed as a pillar in his clan and society. He is however, resistance to change and this leads to his final downfall. He has a strong sense of

Phlebotomy Essay Example | Topics and Well Written Essays - 2500 words
Phlebotomy - Essay Example Professionalism is required while medical assistants work with patients. Therefore, efficiency, competence and a show of concern to patient needs and feelings are crucial (Lindh, Poole, Tamparo, & Dahl, 2010). A phlebotomist should understand the blood circulatory system and the composition of blood so as to be able to collect blood from an individual or patient. For instance, blood forms in the body organs, and bone marrow is responsible for the formation of blood cells. Blood is produced in sites such as the spleen, thymus and the lymph nodes (Lindh, Poole, Tamparo, & Dahl, 2010). Blood performs crucial functions in the body such as transporting oxygen to body tissues and organs and removing carbon dioxide from such organs and tissues, the waste product of functions of the organs and tissues. In addition, blood carries nutrients to all parts of the body and removes wastes products, which it moves to organs such as the kidney, lungs, liver and the skin for excretion (Lindh, Poole, Tamparo, & Dahl, 2010). Components of the blood circulatory system include the heart, veins, arteries and capillaries. The heart is responsible for the pumping of blood through the body in arteries, veins and capillaries (Lindh, Poole, Tamparo, & Dahl, 2010). Arteries enable blood to flow away from the heart while blood flows into the heart through veins. Capillaries connect veins and arteries. Arteries are thick walled to enable them withstand pressure, and they normally branch to form arterioles which also branch to form capillaries (Lindh, Poole, Tamparo, & Dahl, 2010). Capillaries join to form venules which supply blood back to the veins. Blood is composed of the liquid part which is plasma, red blood cells, platelets and white blood cells (Hoeltke, 2013). The circulatory is divided into two systems and these are the pulmonary system and the systemic system. Blood is circulated to the lungs for enrichment

Stem Cell Research Paper Example | Topics and Well Written Essays - 1250 words - 4
Stem Cell - Research Paper Example Scientifically, stem cells can be defined as primitive unspecialized types of cells that can renew themselves and develop into more mature cells with specialized functions. They are fertilized eggs that are less than a week old. The typical scientific definition of stem cells describes them as "blank cells that can be turned into specialized cells such as heart cells, or any kind of tissue in the body, such as skin, muscle, or the brain" (Gupta). One of the distinguishing characteristics of stem cells is that they have the ability to renew themselves for long periods through the process of cell division. Also, stem cells can be converted to become cells with special functions, such as the lung cells, liver cells, the beating cells of the heart muscle or any other specialized cells (Rockville). There are primarily two types of them: embryonic stem cells and adult stem cells. Each of these two types has its own functions and characteristics that are different from the other. Before stu dying stem cells of human beings, scientists made a lot of experiments on stem cells from mouse embryos for years. These experiments on the mouse embryos led to the successful discovery of the ways of isolating stem cells from human embryos and grow them in the laboratory. At the beginning, these human embryonic stem cells were created for infertility purposes through in vitro fertilization procedures. When they were no longer needed for that purpose, these stem cells are usually donated for research and experiment with the consent of the donor (Rockville). Due to the extreme importance of stem cells in organ transplantation and other medical purposes, it is ethical to conduct more research on stem cells, as long as these experiments do not distort any of the established religious beliefs. Objectives: Most scientists agree that stem cells have many medical advantages. Some scientists even regard stem cells as offering a great potential for the alleviation of human suffering, as they can provide cure for a number of diseases. Millions of people around the world suffer from diseases that may be treated more effectively with stem cells. These diseases include Alzheimer, Diabetes, Parkinsonââ¬â¢s, and heart disease, and certain types of cancer (Takahashi et al.). In addition, stem cells can offer great help in many different areas of health and medical research. For example, studying stem cells helps us to understand the mechanism of their transformation into the various specialized cells that are essential for the existence of human beings. By becoming aware of the way they transform into other cells in the human body, scientists will gain better understanding of normal cell development, which will allow them to correct the errors in these sells, which cause the medical conditions from which human beings suffer. Besides, a third medical advantage of stem cells is that they provide an opportunity of making cells and tissues for medical therapies. In other words , stem cells can be used to replace those tissues or organs in the human body that are diseased or destroyed. Prior to the discovery of the stem cells technology, the only way to transplant a new organ in a human body was by donation from other persons. However, a new discovery about stem cells illuminated the scientists about the possibility of using these stem cells in transplantation. This use of stem cells in organ transplantation solves many of the problems caused by organ donation from oth
