Organ Transplant Research Paper Example | Topics and Well Written Essays - 1500 words

Organ Transplant - Research Paper Example The determination of the process of organ transplantation is an important subject matter in organ transplantation. It increases on consciousness and awareness on the issue of organ transplantation. There are different phases in the process of organ transplant. These include the determination of organ facts, the possible diseases, the devices, organ allocation, the waiting list and the hospitalization and surgery (United Network for Organ Sharing, 2011). Determination of Organ Facts First is the determination of the organ facts. This includes the defective organs of the patients needing replacement. The common organs transplanted are liver, kidney, pancreas, heart, lung and intestine. Kidney is one of the organs susceptible to damage which can lead to the lost of function specifically the removal of waste from the body through filtration then urination. Regulations of blood pressure, blood volume and chemical or electrolyte composition of the blood, are included in the main functions of the kidney. Included in the kidney diseases that can lead to the need for organ transplant are polycystic kidneys, nephrosclerosis, chronic pyelonephritis, glomerulonephritis, diabetes mellitus, kidney stones, renal cell carcinoma ad Wilm’s tumor (United Network for Organ Sharing, 2011). Liver is another organ susceptible to failure since it’s one of the largest organs with important function such as processing of carbohydrates, fats and proteins, and storage of vitamins. It is responsible for the substance in blood clotting. ... It is responsible for the substance in blood clotting, bile for fat digestion and can break down toxic substances in drugs and alcohol. Diseases such as primary sclerosing cholangitis, acute hepatic necrosis, cirrhosis, metabolic diseases, portal hypertension, hepatitis, liver tumors and biliary atresia (United Network for Organ Sharing, 2011). Pancreas is another organ with the main role of producing enzymes for digestion as well as insulin which functions as a regulator of blood sugar in the body. A need for organ transplant can be caused by diabetes mellitus type II. Heart is another organ of importance commonly transplanted. It pumps blood that distributes nutrients and oxygen and gathers wastes and carbon dioxide from different parts of the body. It can acquire diseases and malfunctions caused by coronary heart disease, cardiomyopathy, congenital or valvular heart diseases, and hypertensive heart disease. Also located near the heart is the lung which is described as a spongy org an in the chest that functions for breathing. A person needs organ transplant when the lungs are damaged through COPD, idiopathic pulmonary fibrosis, emphysema, primary pulmonary hypertension, cystic fibrosis, and alpha-1 antitrypsin deficiency. Intestines are also included in the organs transplanted. It can be damaged through short gut syndrome and other malabsorptive bowel problems (United Network for Organ Sharing, 2011). Waiting List of Organs One of the most important factors in the process of organ transplantation is the waiting list. In the study of the United States waiting lists of candidates by organ released on April 1, 2011, the largest composition is composed of people who needs kidney transplant, which

A Guide to Successful Communication and Study Essay -- teamwork, commun

According to a survey done by a statistical website ‘Nation Master', twenty one out of thirty four OECD(Organization of Economic Cooperation and Development) member countries ranked 14.4% for an average percentage of single households in 2013. To be more specific, the United States, Australia, Canada, Sweden and Japan are the top five countries ranking the highest percentages of population living alone, nearly up to 26% in common. These statistics clearly demonstrate how prevalent phenomenon ‘individualism’ is in recent days. In other words, people nowadays are more accustomed to being alone than being together. The time is now when importance of working together must be highlighted. Particularly, pinpointing an emphasis on teamwork in the universities seems notably demanding. Therefore, it is fundamental for universities to increase group activities for the students on account of three main benefits teamwork can bring; enhancing communication skills, improving lea dership and raising responsibility. To begin with, teamwork provides opportunities for the university students to enhance communication abilities. Teamwork is an activity done by more than one person with a same goal. The more people there are, the more perspectives there must be. In other words, conflicts from different viewpoints of each member are unavoidable in a disparate group of individuals. For example, there was a survey done by Korea Herald toward 522 Korean university students about the most common trouble that occurred during teamwork. 38.3% of the students chose difficult time scheduling for team meetings. 25.5% answered an unsatisfactory division of tasks for each member, and 14.8% pointed out a hardship in uniting opinions among the members.

Ariel and Caliban Relationship

At the beginning of the Tempest, Prospero finds two other inhabitants on the island, Caliban and Ariel. Ariel is portrayed as a mythical being coming from the heavens; he acts upon explanation and motive, being connected with God. Caliban, on the other hand, represents a creature descending the devil. He acts upon instinct, and is a creature of the wild. Both of them desire freedom, but Caliban is the one who is enslaved by Prospero.Prospero, being the Duke of Milan, also controls Ariel in order to help him succeed in his study of magic. This magic keeps Caliban subjugated under Prospero’s control. It seems simple to understand the relationship between the three- Prospero has two servants and their names are Caliban and Ariel. But really, Caliban seems enslaved while Ariel seems more as an â€Å"indentured servant. † Why should Prospero favor Ariel more than Caliban?They both contribute to the same amount of work and both are under Prospero’s control. It is obvio us throughout the play that Prospero enjoys the company of Ariel more than Caliban, as Caliban tries to kill him and Ariel is a peaceful kind spirit. But looking through the postcolonial lens, it seems as if Caliban deserves nothing less than Ariel, as he has as much knowledge and leadership as Prospero. Throughout the whole play, Prospero uses harsh language upon Caliban, and vise versa.This shows that Caliban once had love for Prospero, but is now angry with Prospero for taking his island. While Caliban is ordered to fetch wood and make fire, Ariel is given more important tasks, as Prospero depends on her. Caliban is usually reluctant to complete the orders of Prospero, while Ariel is willing to help his master. Simply, Prospero is the master of two beings: one being good, and the other being bad. Ultimately, the relationship between Ariel and Prospero completely juxtaposes between that of Caliban and Prospero.

Mehrgarh (Pakistan) Life in the Indus Valley Before Harappa

Mehrgarh is a large Neolithic and Chalcolithic site located at the foot of the Bolan pass on the Kachi plain of Baluchistan (also spelled Balochistan), in modern day Pakistan. Continuously occupied between about 7000 to 2600 BC, Mehrgarh is the earliest known Neolithic site in the northwest Indian subcontinent, with early evidence of farming (wheat and barley), herding (cattle, sheep, and goats) and metallurgy. The site is located on the principal route between what is now Afghanistan and the Indus Valley: this route was also undoubtedly part of a trading connection established quite early between the Near East and the Indian subcontinent. Chronology Mehrgarhs importance to understanding the Indus Valley is its nearly unparalleled preservation of pre-Indus societies. Aceramic Neolithic founding 7000 to 5500 BCNeolithic Period II 5500 to 4800 (16 ha)Chalcolithic Period III 4800 to 3500 (9 ha)Chalcolithic Period IV, 3500 to 3250 BCChalcolithic V 3250 to 3000 (18 ha)Chalcolithic VI 3000 to 2800Chalcolithic VII-Early Bronze Age 2800 to 2600 Aceramic Neolithic The earliest settled portion of Mehrgarh is found in an area called MR.3, in the northeast corner of the immense site. Mehrgarh was a small farming and pastoralist village between 7000-5500 BC, with mud brick houses and granaries. The early residents used local copper ore, basket containers lined with bitumen, and an array of bone tools. Plant foods used during this period included domesticated and wild six-rowed barley, domestic einkorn and emmer wheat, and wild Indian jujube (Zizyphus spp) and date palms (Phoenix dactylifera). Sheep, goats, and cattle were herded at Mehrgarh beginning during this early period. Hunted animals include gazelle, swamp deer, nilgai, blackbuck onager, chital, water buffalo, wild pig and elephant. The earliest residences at Mehrgarh were freestanding, multi-roomed rectangular houses built with long, cigar-shaped and mortared mudbricks: these structures are very similar to Prepottery Neolithic (PPN) hunter-gatherers in early 7th millennium Mesopotamia. Burials were placed in brick-lined tombs, accompanied by shell and turquoise beads. Even at this early date, the similarities of crafts, architecture, and agricultural and funerary practices indicate some sort of connection between Mehrgarh and Mesopotamia. Neolithic Period II 5500 to 4800 By the sixth millennium, agriculture had become firmly established at Mehrgarh, based on mostly (~90 percent) locally domesticated barley but also wheat from the near east. The earliest pottery was made by sequential slab construction, and the site contained circular fire pits filled with burnt pebbles and large granaries, characteristics also of similarly dated Mesopotamian sites. Buildings made of sun-dried brick were large and rectangular, symmetrically divided into small square or rectangular units. They were doorless and lack of residential remains, suggesting to researchers that at least some of they were storage facilities for grains or other commodities which were communally shared. Other buildings are standardized rooms surrounded by large open work spaces where craft-working activities took place, including the beginnings of the extensive bead-making characteristic of the Indus. Chalcolithic Period III 4800 to 3500 and IV 3500 to 3250 BC By the Chalcolithic Period III at Mehrgarh, the community, now well over 100 hectares, consisted of large spaces with groups of building divided into residences and storage units, but more elaborate, with foundations of pebbles embedded in clay. The bricks were made with molds, and along with fine painted wheel-thrown pottery, and a variety of agricultural and craft practices. Chalcolithic Period IV showed a continuity in pottery and crafts but progressive stylistic changes. During this period, the region split into small and medium sized compact settlements connected by canals. Some of the settlements included blocks of houses with courtyards separated by small passageways; and the presence of large storage jars in rooms and courtyards. Dentistry at Mehrgarh A recent study at Mehrgarh showed that during Period III, people were using bead-making techniques to experiment with dentistry: tooth decay in humans is a direct outgrowth of a reliance on agriculture. Researchers examining burials in a cemetery at MR3 discovered drill holes on at least eleven molars. Light microscopy showed the holes were conical, cylindrical or trapezoidal in shape. A few had concentric rings showing drill bit marks, and a few had some evidence for decay. No filling material was noted, but tooth wear on the drill marks indicate that each of these individuals continued to live on after the drilling was completed. Coppa and colleagues (2006) pointed out that only four of the eleven teeth contained clear evidence of decay associated with drilling; however, the drilled teeth are all molars located in the back of both lower and upper jaws, and thus are not likely to have been drilled for decorative purposes. Flint drill bits are a characteristic tool from Mehrgarh, mostly used with producing beads. The researchers conducted experiments and discovered that a flint drill bit attached to a bow-drill can produce similar holes in human enamel in under a minute: these modern experiments were not, of course, used on living humans. The dental techniques have only been discovered on only 11 teeth out of a total of 3,880 examined from 225 individuals, so tooth-drilling was a rare occurrence, and, it appears to have been a short-lived experiment as well. Although the MR3 cemetery contains younger skeletal material (into the Chalcolithic), no evidence for tooth drilling has been found later than 4500 BC. Later Periods at Mehrgarh Later periods included craft activities such as flint knapping, tanning, and expanded bead production; and a significant level of metal-working, particularly copper. The site was occupied continuously until about 2600 BC, when it was abandoned, about the time when the Harappan periods of the Indus civilization began to flourish at Harappa, Mohenjo-Daro and Kot Diji, among other sites. Mehrgarh was discovered and excavated by an international led by French archaeologist  Jean-Franà §ois Jarrige; the site was excavated continuously between 1974 and 1986 by the French Archaeological Mission in collaboration with the Department of Archaeology of Pakstan.
