Report on 3d Bio Printer free essay sample

A 3D Bio-Printer is a device, in which, a Human Organ is scanned, and a 3D dimension of a brand new organ is created and printed using the person’s own cell or stem cells as â€Å"ink. † With just a small amount of cell used from the patient’s body. 1 The 3D bio-printers include a software interface that allows engineers to build a model of the tissue construct before the printer commences the physical constructions of the organs cell-by-cell using the automated, laser-calibrated print heads. The printer is the result of collaboration between Australian engineering firm Invetech, and Organovo, a regenerative medicine company based in San Diego, California. Organovo selected Invetech in May 2009 as its technology development partner and asked the company to design and develop a highly integrated, extremely reliable and simple to use 3D bio-printer system, which could then be transferred to manufacture and commercial sale. Now, just eight months later, Invetech has delivered the first production model 3D bio-printer to Organovo.

Scientists and researchers will have the power to create organs to use as well, simply for testing medical products. Researchers don’t need to use the animals anymore! So, it won’t be long when the time comes that all you have to do is make a phone call or a simple trip to the doctor’s office when you need new organs. The thought of being able to grow organs gives me goosebumps. However, if this technology is controlled and used properly, as I’ve said, the possibilities are endless.

Relationship Between Body and Consciousness by Jean

Relationship Between Body and Consciousness by Jean Introduction According to Jean-Paul Sartre, understanding of the body is obscured by many factors. Moreover, its relation to consciousness is masked. In addition, its problems are concealed. He argues that this is attributed to the complexities surrounding consciousness. For instance, the body has laws that govern it.Advertising We will write a custom book review sample on Relationship Between Body and Consciousness by Jean-Paul Sartre specifically for you for only $16.05 $11/page Learn More Moreover, it is observable as matter. Furthermore, the body can be defined from the outside. However, this is not the same as with consciousness. Consciousness is reached by peculiar intuitions, which are inside the body. This complicates its understanding since one has to relate it to the body organs. Sartre claims that after internal intuitions, one can then unite consciousness to the various body organs for action. Therefore, Sartre tries to define the relationship be tween body and consciousness. In addition, he tries to explore the problems of the body. This paper will review Sartre’s theories on the body as well as its relation to consciousness. The Body Jean-Paul argues that consciousness is quite complex to understand. However, he finds it quite easy to cognize the body. Interestingly, once consciousness has been achieved, then its unity to the various body organs such as the nervous system becomes increasingly complex to analyze. However, he argues that the difficulties arise from trying to connect one’s conscience with other people’s bodies. Interestingly, he notes that no one has ever seen or will ever see his/her brain. That is, people look to others for explanation about their bodies. In that sense, he sees one’s body organs as his/her property than as his/her being. Through this, he notes that observable body organs such as the eye, the legs, and the ears, among others can only be seen in a single perception , which does not involve itself.Advertising Looking for book review on philosophy?

Therefore, he claims that people deal with different orders of reality. In this regard, he rejects the notion of double sensation because these two orders of reality are in incommunicable levels. In essence, he claims that the orders of reality are radically distinct. Sartre also agrees with other theorists that the discovery of the body as being is real. However, he claims that the body is indeed a being for others. On this, he argues that people usually link their consciousness of objects on the body of others. Sartre gives an example of an inverted image seen from the lens to show that conscience can refuse to be bound by the laws of objec ts so that it conveys an upright image. In this regard, he posits that it is only possible to reflect on the nature of the body by first establishing the order of reflection. This should conform to the order of being which states that people cannot keep confusing the levels of ontology. Moreover, they must first look at the body as being-for-itself then as being-for-others. In addition, he argues that the two orders of the body are in both incommunicable and different levels so that they cannot be unified. In this regard, he continues that being-for-itself has to be wholly consciousness and wholly body. Moreover, it should be noted that the two (consciousness and body) cannot be unified. Similarly, he posits that being-for-others should also be wholly body and the body wholly psychic.Advertising We will write a custom book review sample on Relationship Between Body and Consciousness by Jean-Paul Sartre specifically for you for only $16.05 $11/page Learn More Being-for-itself: Facticity From the discussion above, Sartre rejects Descartes’s theory that knowing the soul is easy as compared to knowing the body. In essence, it rejects the observations in the â€Å"Cartesian cogito.† Sartre argues that the facts of the body are completely different from the facts of thought. To prove this, he says that facts of the body are accessible through divide providence while facts of thought can be accessed through reflection. That is, the facts of consciousness manifest in signs, which drives the body out of conscience. This makes it difficult to reunite the two since the body has become a body-of-others. He commends the idea that idealism was right in positing that the world is made out of relation. However, he believes that idealism is not entirely true because it was taken from Newtonian science, which conceived relation from another relation known as relation of reciprocity. That is, idealism succeeded only in making the point of absolute objectivity. Moreover, Absolute objectivity made it possible for the world to exist without people thereby nullifying its effect. He therefore claims that the body is in the order of for-itself. In this regard, the body must be defined with the world. He therefore concludes that the body is one’s motivation without being its foundation. Sartre agrees with Plato on the fact that the body individualizes one’s soul. However, he does not agree with some theorists that it was made because of a demiurge. Moreover, he faults Plato in his belief that soul can be separated from the body at death. That is, he believes that one’s soul cannot detach itself from individualization because soul is the body as far as Sartre is concerned. To prove this, he gives an example of a sense, which he believes cannot be given before or after the sensible object.Advertising Looking for book review on philosophy? Let's see if we can help you! Get your first paper with 15% OFF Learn More He also commends Bachelard for reproaching phenomenology for inadequacy in coefficient of adversity. However, he faults him partly on the fact that instrumentality is primary. Moreover, he claims that one’s body extends through the tool that it utilizes. In this regard, he joins action and sensation as one. Moreover, he states that the body is a conscious structure of its own consciousness. Sartre believes that body organs give the body as it is acted upon as opposed to giving as it acts. Since he believes that the appearance of the body is not capable of giving rise to new complications, he concludes by stating that the body is one’s facticity of being. Moreover, since on one aspect the body appears as being for itself, on the other aspect it appears as an object, which is visible in one’s body organs. This shows that in accordance with the former level, the body has no physiology but on the latter level, it has physiology due to the presence of organs. In esse nce, Jean-Paul Sartre believes that the body is being-for-itself as well as being an object. In accordance with the former, he claims that the body has several aspects while one lives. One of the aspects includes consciousness, in which he considers the body as being a matter being-for-itself. The second aspect is perception. In this regard, he argues that when people perceive other bodies, they do so in a special manner. This kind of perception is completely different from the perceptions of lifeless things. Thirdly, Sartre believes that one can perceive his/her own body under particular circumstances. One therefore sees himself/herself as an object even without involvement of other people (being-in-itself). He utilizes numerous examples and arguments from theorists such as Plato, and Bachelard, among others to prove his arguments. Moreover, he draws information from many sources with an in depth analysis of information for the audience. It can be said the Sartre tries to define th e body and consciousness. Moreover, he tries to relate them with a view to establishing a common description and cognition of both. This is quite difficult considering the complexities involved. However, it should be noted that he rightly rejects theories that suggest that understanding the soul is easy as compared to understanding the body. Conclusion Jean-Paul Sartre tries to define the human body. He also tries to define consciousness. In both cases, he agrees that human body can be defined in different levels. For instance, he defines it as a being-for-itself and as an object. In the process, he disputes many theories including those posited by Plato, Descartes, and Bachelard, among others. However, it is important to note that he does not dispute their theories entirely but borrows from them to support his theories. Nonetheless, his understanding of the body and soul is quite apprehensive given that he rejects almost all theories posited by others. Moreover, he claims that oneà ¢â‚¬â„¢s soul cannot be detached from his/her body even in death. This brings controversies especially with religious people who believe in the separation of soul from body as well as in their distinctiveness. In addition, his arguments are largely theoretical as well as philosophical. This makes it difficult to defend his theories.

The Battle of Peleliu in World War II

The Battle of Peleliu in World War II The Battle of Peleliu was fought September 15 to November 27, 1944, during World War II (1939-1945). Part of the Allies island-hopping strategy, it was believed that Peleliu needed to be captured before operations could commence against either the Philippines or Formosa. While planners had originally believed that the operation would only require a few days, it ultimately took over two months to secure the island as its nearly 11,000 defenders retreated into a system of interconnected bunkers, strong points, and caves. The garrison exacted a heavy price on the attackers and the Allied effort quickly became a bloody, grinding affair. On November 27, 1944, after weeks of bitter fighting, Peleliu was declared secure. Background Having advanced across the Pacific after victories at Tarawa, Kwajalein, Saipan, Guam, and Tinian, Allied leaders reached a crossroads regarding future strategy. While General Douglas MacArthur favored advancing into the Philippines to make good his promise to liberate that country, Admiral Chester W. Nimitz preferred to capture Formosa and Okinawa, which could serve springboards for future operations against China and Japan. Flying to Pearl Harbor, President Franklin Roosevelt met with both commanders before ultimately electing to follow MacArthurs recommendations. As part of the advance to the Philippines, it was believed that Peleliu in the Palau Islands needed to be captured to secure the Allies right flank (Map). Fast Facts: Battle of Peleliu Conflict: World War II (1939-1945)Dates: September 15 to November 27, 1944Armies Commanders:AlliesMajor General William RupertusRear Admiral Jesse Oldendorf1st Marine Division (17,490 men), 81st Infantry Division (10,994 men)Japanese:Colonel Kunio Nakagawaapprox. 11,000 menCasualties:Allies: 2,336 killed and 8,450 wounded/missingJapanese: 10,695 killed and 202 captured The Allied Plan Responsibility for the invasion was given to Major General Roy S. Geigers III Amphibious Corps and Major General William Rupertuss 1st Marine Division was assigned to make the initial landings. Supported by naval gunfire from Rear Admiral Jesse Oldendorfs ships offshore, the Marines were to assault beaches on the southwest side of the island. Going ashore, the plan called for the 1st Marine Regiment to land to the north, the 5th Marine Regiment in the center, and the 7th Marine Regiment in the south. Hitting the beach, the 1st and 7th Marines would cover the flanks as the 5th Marines drove inland to capture Pelelius airfield. This done, the 1st Marines, led by Colonel Lewis Chesty Puller were to turn north and attack the islands highest point, Umurbrogol Mountain. In assessing the operation, Rupertus expected to secure the island in a matter of days. Colonel Lewis Chesty Puller, 1950. US Marine Corps A New Plan The defense of Peleliu was overseen by Colonel Kunio Nakagawa. Following a string of defeats, the Japanese began to reassess their approach to island defense. Rather than attempting to halt Allied landings on the beaches, they devised a new strategy which called for islands to be heavily fortified with strong points and bunkers. These were to be connected by caves and tunnels which would allow troops to be safely shifted with ease to meet each new threat. To support this system, troops would make limited counterattacks rather than the reckless banzai charges of the past. While efforts would be made to disrupt enemy landings, this new approach sought to bleed the Allies white once they were ashore. The key to Nakagawas defenses were over 500 caves in the Umurbrogol Mountain complex. Many of these were further fortified with steel doors and gun emplacements. At the north of the Allies intended invasion beach, the Japanese tunneled through a 30-foot high coral ridge and installed a variety of guns and bunkers. Known as The Point, the Allies had no knowledge of the ridges existence as it did not show on existing maps. In addition, the islands beaches were heavily mined and strewn with a variety of obstacles to hamper potential invaders. Unaware of the change in Japanese defensive tactics, Allied planning moved forward as normal and the invasion of Peleliu was dubbed Operation Stalemate II. A Chance to Reconsider To aid in operation, Admiral William Bull Halseys carriers commenced a series of raids in the Palaus and Philippines. These met little Japanese resistance led him to contact Nimitz on September 13, 1944, with several suggestions. First, he recommended that the attack on Peleliu be abandoned as unneeded and that the assigned troops be given to MacArthur for operations in the Philippines. He also stated that the invasion of the Philippines should begin immediately. While leaders in Washington, DC agreed to move up the landings in the Philippines, they elected to push forward with the Peleliu operation as Oldendorf had begun the pre-invasion bombardment on September 12 and troops were already arriving in the area. Going Ashore As Oldendorfs five battleships, four heavy cruisers, and four light cruisers pounded Peleliu, carrier aircraft also struck targets across the island. Expending a massive amount of ordnance, it was believed that the garrison was completely neutralized. This was far from the case as the new Japanese defense system survived nearly untouched. At 8:32 AM on September 15, the 1st Marine Division began their landings. The first wave of LVTs moves toward the invasion beaches, passing through the inshore bombardment line of LCI gunboats. Cruisers and battleships are bombarding from the distance. The landing area is almost totally hidden in dust and smoke. US Naval History and Heritage Command Coming under heavy fire from batteries at either end of the beach, the division lost many LVTs (Landing Vehicle Tracked) and DUKWs forcing large numbers of Marines to wade ashore. Pushing inland, only the 5th Marines made any substantial progress. Reaching the edge of the airfield, they succeeded in turning back a Japanese counterattack consisting of tanks and infantry (Map). A Bitter Grind The next day, the 5th Marines, enduring heavy artillery fire, charged across the airfield and secured it. Pressing on, they reached the eastern side of the island, cutting off the Japanese defenders to the south. Over the next several days, these troops were reduced by the 7th Marines. Near the beach, Pullers 1st Marines began attacks against The Point. In bitter fighting, Pullers men, led by Captain George Hunts company, succeeded in reducing the position. Despite this success, the 1st Marines endured nearly two days of counterattacks from Nakagawas men. Moving inland, the 1st Marines turned north and began engaging the Japanese in the hills around Umurbrogol. Sustaining serious losses, the Marines made slow progress through the maze of valleys and soon named the area Bloody Nose Ridge. As the Marines ground their way through the ridges, they were forced to endure nightly infiltration attacks by the Japanese. Having sustained 1,749 casualties, approximately 60% of the regiment, in several days fighting, the 1st Marines were withdrawn by Geiger and replaced with the 321st Regimental Combat Team from the US Armys 81st Infantry Division. The 321st RCT landed north of the mountain on September 23 and began operations. A U.S. Marine Corps Chance Vought F4U-1 Corsair aircraft attacks a Japanese bunker at the Umurbrogol mountain on Peleliu with napalm bombs. US Marine Corps Supported by the 5th and 7th Marines, they had a similar experience to Pullers men. On September 28, the 5th Marines took part in a short operation to capture Ngesebus Island, just north of Peleliu. Going ashore, they secured the island after a brief fight. Over the next few weeks, Allied troops continued to slowly battle their way through Umurbrogol. With the 5th and 7th Marines badly battered, Geiger withdrew them and replaced them with the 323rd RCT on October 15. With the 1st Marine Division fully removed from Peleliu, it was sent back to Pavuvu in the Russell Islands to recover. Bitter fighting in and around Umurbrogol continued for another month as the 81st Division troops struggled to expel the Japanese from the ridges and caves. On November 24, with American forces closing in, Nakagawa committed suicide. Three days later, the island was finally declared secure. Aftermath One of the costliest operations of the war in the Pacific, the Battle of Peleliu saw Allied forces sustain 2,336 killed and 8,450 wounded/missing. The 1,749 casualties sustained by Pullers 1st Marines nearly equaled the entire divisions losses for the earlier Battle of Guadalcanal. Japanese losses were 10,695 killed and 202 captured. Though a victory, the Battle of Peleliu was quickly overshadowed by the Allied landings on Leyte in the Philippines, which commenced on October 20, as well as the Allied triumph at the Battle of Leyte Gulf. The battle itself became a controversial topic as Allied forces took severe losses for an island that ultimately possessed little strategic value and was not used to support future operations. The new Japanese defensive approach was later used at Iwo Jima and Okinawa. In an interesting twist, a party of Japanese soldiers held out on Peleliu until 1947 when they had to be convinced by a Japanese admiral that the war was over.

Ways to Improve Group Productivity within a hospital or medical Research Paper

Ways to Improve Group Productivity within a hospital or medical facility - Research Paper Example In analyzing this problems, this paper focuses on the department of admissions,the department of public relations, the department of social work, and the department of medical records which are found in an hospital organization. This paper gives an explanation on the impact of the problems under consideration, and identifies the policies which administrators within the hospital set up need to enact for purposes of ensuring efficiency in meeting the goals of the hospital organization. This is because if administrators do not develop solutions to the problems the organization faces, chances are high that the hospital might fail to provide better health care services to its customers. This paper contains suggestions ofthe best training program that could enhance group productivity. Lorenzi (2004) denotes that training is a method of continuous appraisal, since the medical staff acquires relevant skills that are essential to serve the current health care needs of the organizations custom ers. This paper has a conclusion, and it is a summary of the main points addressed in it. One of the problems facing group productivity within the hospital set up is the conflict that emanate from lack of a clear guideline on the role of members within a collaborative group. For instance, within the admissions department of the hospital, there is a group that coordinates the admission of patients, another group prepares their admission, while another group arranges for any reservation of a patients admission. These are devise roles within the admission departmentand because of a clear guideline on the role of members who are in this unit, a conflict of roles emanate. For instance, the group that coordinates the admission of patients is headed by a team leader; it is this person who assigns duties, depending on the present circumstance. A situation arises when such an individual did not report for work because of personal or official issues. Members of the group will be confused beca use nobody will assign them duties, leading to each of them carrying out tasks that were not meant for them. This therefore leads to a rise of conflict of roles, and its result is inefficiency in meeting the objectives of the admissions department (Lorenzi, 2005). To improve on this problem, it is important for the organization to develop a policy that will guide in assigning roles to the various members of its staff. To effectively implement this policy, the organization must create an office, whose main responsibility is to monitor the performance of employees in relation to their specific tasks, and how they contribute in meeting the objectives of the organization. Another major problem that arose from the research is lack of an effective communication capability amongst the various members of different groups within the hospital organization. This problem can affect all the departments of the organization, which includes the admissions department, the public relations department , the medical records department, the maintenance and engineering department and the department of social work. This is because communication is the key that drives the growth of any department of an organization. For instance, the duties of the department of public relations are to solve the problems of out and in patients. If the department lacks modernized communication gadgets such as computers, they will be unable to effectively offer this service to their customers (Kongstvedt, 1997).The reason to this argument is because of the modernization of the communication

Liability of Businesses and Customers

Liability of Businesses and Customers What is a corporation? The current legislation that relate to different companies is known as the Companies Act 2006. This treats companies and corporations individually even though they are similar concepts. A corporation is defined as being an artificial person made by law. Corporations exist independent of human beings who are in fact members involved with the entity.What is a crime?This is a wrong doing that is classified by the state as being either a felony or misdemeanour.   These courts look at different crimes as maybe morally wrong and the companies dont deserve retribution. Corporate crime can be defined as an illegal act of omission or commission, punishable by a criminal sanction, by groups of individuals during their work as employees of a legitimate organisation.Development of Corporate LiabilityA series of disasters in the United Kingdom which lead to a mass life loss, such as the Kings Cross Fire in November 1987, also the Piper Alpha oil explosion and the sinking of the Herald of Free Enterprise in 1991 have left a remarkable amount of thought toward considering the criminal liability of corporations. Several factors have affected the development of corporate law. The procedural requirement has been changed by 2.382 of the companies act 1963 this allows different companies and organisations to be represented at any stage of the law suit.Vicarious LiabilityAn employer is in charge for the acts of employees and agents where a normal worker person would be similarly liable. When seeing if a company can take the blame, you must take into consideration different terms of the things creating the offence. This will require mens rea, it can also restrict liability without imposing liability. This normally arises from offences of strict liability. This doesnt need to be intentional or recklessness just needs one or more elements in the actus reus. Corporate Liability Offences Requiring Mens ReaAs noted, companies are legal persons. They can also be c riminally responsible for multiples offences requiring mens rea by the application of the principle that consists of identification. Of those who represent the case study known as the directing mind and will imputed to the company.The leading case of Tesco Supermarkets LTD v Nattress restricts the ability to apply this principle in court because of the actions that were made by the Board of Directors and perhaps other people who are higher in the pecking order than officers can carry out functions of management and speak act as the company. Jurisdictional IssuesIt is vital that the different jurisdictional interests are intentionally planned. Taking into consideration different domestic crimes and prosecution, agencies that can and can also not be police are usually involved in investigating and prosecuting different offences and liabilities. Prosecutors should be careful of the rules and regulations set out in The Prosecutors Convention and use communication with any other agency t hat has relevance at an early stage. In respect to multiple overseas investigations and prosecutions and the judicial network play a vital role in the coordination of prosecutions. This includes many cases with concurrent jurisdiction between the United Kingdom and the United States which has been issued by Attorneys General of the respective jurisdictions and the Lord Advocate.Charging Companies Additional Public Interest Factors to be ConsideredWhere the evidence provides many different prospects of convictions, the person who is prosecuting whether a prosecution is what the public want, in relation to the case of Code for Crown Prosecutors. The higher the severity of the offence committed it, the more likely it is that prosecution will be necessary. The impact of offending in other countries, not just the consequences in the UK, should be considered. The prosecutor must balance factors for and against prosecution. Public interest factors affect the decision to prosecute usually d epend on the severity of the offence or the circumstances of the suspect.

Salmon Management in the Pacific Northwest

1. Do we, as a region and a nation, need salmon? Why or why not? When is the cost too high or priorities misplaced? The Pacific Northwest region that includes areas like in California, Oregon, Washington, Idaho, and southern British Columbia and the USA as a whole need salmon fish. FAQ, (unpublished) clarifies that the reason for this is that, approximately one hundred and thirty-seven species of both plants and animals depend on the salmon fish for their survival. According to Manning, (1996), there exist a mutual relationship between the forest and the salmon fish. He states that forest need salmon fish as much as salmon fish need them. Forests gain carbon and nitrogen from the salmon fish while salmon fish gain oxygen and other nutrients from the forests. Some forest species which depend on nutrients or carbon and nitrogen gases will die if the salmon fish was to reduce in number or was to get extinct. The salmon fish is therefore very important maintaining biodiversity or ecological diversity. The cost of sustainable conservation of salmon fish is very expensive especially in the wake of the global climate change. Salmon fish requires a very unique habitat which is large and cold. According to Lackey, (2009), billions of dollars have been used in trying to conserve salmon fish with very little success due to the global climate change. The major river; River Klamathi, where the salmon fish thrive in, has experienced serious ecological versus economic conflict with the farmers around the region preferring to utilize the water for agriculture, while the environmentalist on the other hand prefer conservation of the water for salmon conservation. This therefore has forced the communities living around the region to continue with their farming activities but with some limit, although this also affects the development fish in this region since the farming activities impacts negatively on their growth and survival since they utilize the same water form the river for irrigation. Henry and Mote, (unpublished), are of the view that the variations in climate has affected the development of salmon fish especially the high temperatures that cause the coastal ocean waters to warm thus reducing the ability of the salmon fish to reproduce in large numbers. The global climatic change is inevitable and however how much effort is put towards conservation of the salmon fish, it we might not be able to achieve much. The much anticipated changes in the Obama Administration has also not yielded any fruit since the policies in this administration aimed at protecting and conserving the endangered species is more or less the same as those of the previous government. The policies have leaned mostly towards production of more food through agriculture and production of electricity. This is very dangerous for the survival of anadromous fish like salmon which depends on fresh water for hatching of its eggs. Salmon fish is of great importance to those living around the region for many reasons. Food is basic human need which in this case is derived from the salmon fish, that is, these people depend on the fish for food. It provides protein to the body, besides many other nutrients and vitamins. It’s also used in industries to manufacture variety of food products and thus it boots the economy of the region besides providing employment opportunity to these people. Factories have been established specifically to utilize the salmon fish as the main raw material. This gives individuals from the communities living around this region and the USA as a whole, employment opportunity. Again salmon fish is viewed as a natural resource for tourism which earns the country foreign exchange. 2. In September 2002, estimates ranging from 30,000-80,000 Chinook and Coho salmon died in the Klamath River. If these fish had survived to spawn they would have comprised the eighth largest salmon run since 1978. Why did this happen? What have been the short-term (days to weeks) and long term (months to years) effects? How could this be prevented from happening again? Lackey, (2009), states that the major cause of this was water pollution. The irrigation project which was started on River Klamath was the major cause of this massive death of Chinook and Coho salmon fish. Thos plus the many industries in the region led to the construction of many dams in the upper basin of the river which caused interference in the quality of water of the fresh river. According to The Bush Administration's Environmental Record, (unpublished) and; BEST and WSTB, (2008) this irrigation project and the industries led to low water levels in the lower Klamathi River thus leading to eutrophication of the water in the river and rising of water temperatures caused by construction of dams. Salmon fish depends on very cold temperatures. This in turn caused a missing link in the food chain since Chinook and Coho salmon fish acquires its food in the fresh waters whenever it migrates to this region; and gill rot in the fish and hence most of them that were not able to adapt died. The deaths of these two species led to a serious decline of fish in the region which in turn has also led to a decline of wealth to the communities living around the region. According to Arkush, (2005) this has caused an increase in poverty in the region and that since salmon runs have decreased, artificial hatcheries have to be built for them. This is uneconomical since artificial hatcheries are costly and very expensive to maintain compared to if the fish was to thrive in natural ecosystem. There was a short term increment of micro-organism and that depend on nutrients from decomposed salmon fish. With time there has been a slow decline of forest that depended on the salmon fish for growth and development. Coho habitat has been seriously degraded in the tributaries. Lack of cover and impairment of substrate through deposition of sediments are common. Woody debris, which is critical as cover for young fish, has largely been lost as a result of human activity. According to Henry and Mote (unpublished) excessive depletion of flow may separate fish from adequate habitat in the last half of summer. Endangered and Threatened Fishes in the Klamath River Basin, (2010) states that human activities around the region have caused serious depletion of the Coho salmon since debris from the woods that used to protect young fish has diminished. Thus there has been a serious decline in the commercial catch of the fish which has in turn led to the closure of some industries like the salmon troll industry in 2006 or a decline in the operations in some industries a long the region. This translates negative impacts to economy of the country. In order to the country from losing this important natural resource, more efforts towards its conservation must be applied. There is need to come up with policies of sustainable development in harvesting salmon fish. Policies aimed at protecting the salmon fish in the wildlife act, need to be made more applicable and should be fully implemented. There is also the need to create awareness on the need to conserve salmon fish as an endangered species. According to Arkush, (2009), it should include increasing fish resistance to warm temperature and diseases, and reducing the amount of input myxospores into water. 3. Why do different salmon species, and even different salmon stocks within a species, have such different life-history strategies? For example, compare Coho and Pink salmon or compare an Alaskan stock of Chinook with a Californian stock of Chinook. DEFINE the specific comparison you are going to make. What are the advantages and disadvantages of the life-history strategies of each species? Which strategy do you think will work better in a changing climate? National Park Service US Department of the Interior, (Unpublished) states that salmon fish has an anadromous life history strategy which enables it to bring nutrients from the ocean back into rivers by migrating from the ocean at some stage in life to the fresh mater rivers; and thus the wildlife community as a whole. Thus an anadromous fish are those that live in the fresh water rivers at their initial stages of their lives and migrate to ocean for their later lives. They require the fresh water rivers for spawning and egg incubation (Fish, unpublished). Both Coho and Pink salmon spend more than a year in the fresh water in the rivers and they both deposit their eggs on gravel beds in the fresh waters. Coho salmon hatch their eggs during winter while Pink salmon hatch their eggs during spring time. The young Pink Salmon then leave for the sea immediately to grow there in the salt water while Coho salmon spend three years in slow moving streams or lakes till it matures into adult Coho salmon before finally moving into the ocean water. When the Pink salmon enter the fresh water streams, they do not feed there but instead provide food and nutrients to the environment which includes other fish, birds, micro organisms and other animals (National Park Service US Department of the Interior, unpublished). They die immediately after laying eggs and dropping them on the gravel. Their carcasses decompose to produce nutrients to other micro-organisms and plants, while their dead bodies are fed on by birds and other fish. On the other hand, Coho salmon competes for food with other animals in the fresh water streams since they have to live in this habitat for a longer time. The number of Pink salmon is in abundant since they are able to survive in any water and their ability to feed in the oceans and thus not affected by the environmental variations in the fresh water rivers, and besides, can also survive in any water and take a shorter period to mature (National Park Service US Department of the Interior, unpublished). Unfortunately, Pink salmon have a very short life span of about two years (Salmonds, unpublished) which most of it is spent in the oceans. Coho salmon have longer life span but the female stays for only eighteen months in the ocean before moving to the fresh water. That is, it spends most of its life in the fresh water. Pink Salmon therefore can best survive in wake of the global climatic change since they can survive in any water and their young ones immediately transfer to the sea to mature after being hatched. Their ability to survive in any water gives advantage to survive in various conditions that might be caused by the global climatic changes. Moreover; they do not depend on the food in fresh waters and instead, provide food when they die after laying eggs. Thus they can easily adapt to changes in the environment than Coho salmon which is very vulnerable to high summer temperatures (Wild Coho Salmon, 2007).
