The Deepwater Horizon Oil Spill Analysis Essay Example | Topics and Well Written Essays - 750 words

The Deepwater Horizon Oil Spill Analysis - Essay Example The Deepwater Horizon Oil Spill Analysis â€Å"The oil spill threatens to create large-scale environmental disaster due to factors such as the toxic effects of petroleum and oxygen depletion in the water† (Turner 2010). The pollution caused due to the chemicals used to clean-up the oil spill can damage the food chain of the animals due to depletion of oxygen content in the water. Besides polluting the beaches around the actual source of spill, the oil could flow with the water current and move to the Atlantic Ocean. There it can pose a serious threat to the wild life, if they tend to swim to the area from other places. Thus, the spill has a disastrous environmental impact globally. The clean-up efforts are also not easy and the toxic compounds in the air caused due to the pollution from the spill pose great threat to the workers involved in the effort. This can be seen from the fact that ten workers involved in the clean-up operation had to be admitted to hospital with respiratory tract problems. The seafood industry is also highly endangered by this disaster as the commercial sea food swamps in the coastal areas of the spill can be contaminated. The spill has been estimated to have cost the fisheries industry an estimated $2.5billion as per initial calculations (Turner 2010). Tourism industry has also been hit badly as the beaches have to be closed down. Tourists have cancelled their vacation bookings at beaches which are yet untouched by the oil from the spill.

Fight Club - How Multiple Identities Were Portrayed in The Film Essay

Fight Club - How Multiple Identities Were Portrayed in The Film - Essay Example The symptoms vary over time according to different conditions (Ringrose 64). The movie, Fight Club, clearly shows how D.I.D can affect a person. This is as discussed below. Dissociative identity disorder normally tends to be exhibited by an individual during highly traumatizing, painful, and violent moments (Ringrose 123). This is fully exhibited in Fight Club when Jack fights to put off the bombs set by Tyler for the destruction of the credit card companies. The trauma at the scene transforms him into someone else such that he acquires two personalities while being in one body. He has exactly to know the side of the body where Tyler is hiding so that he can shoot him. He uses sense and conscience to determine the side Tyler is hiding and finally manages to shot him (Palahniuk 13). The main symptoms of the disorder are depression, sleep disorders like insomnia, and sleep walking. Mood signs, headache, panic attacks, and phobias can also be part of the first symptoms of the disorder. The disorder makes an individual perceive intrusive thoughts and emotions, which make the individual act in accordance with such emotions and thoughts (Ringrose 63). It also causes them to forget information and thus act as a blank personality driven by the implanted thoughts and no logic or reasoning. This is the most dangerous part of the disorder. It thus makes it necessary to take good care of such patients. The treatment of such a disorder is not yet fully defined but is mostly dependent on past case studies. The reaction a patient gives is the one that gives the doctor a clue about the required action to be taken. A patient is handled according to how a previous patient was handled (Ringrose 78). It is thus important to notice any early symptoms for the treatment to be easier. Complicated cases can be difficult to handle. Considering Fight Club as a movie, identity is used as a style. Identity is used to show how the character of Jack, the narrator of the movie has the same pe rsonality with Tyler. This is well exhibited at the end of the movie when Jack has to shoot through his cheek so that he can hurt Tyler (Palahniuk 23). It clearly shows how Jack and Tyler have merged into one person and are operating using the same body and characteristics. Identity is also exhibited at places when people are referring to Jack as Tyler. This was mainly when Jack was following the trail of places where Tyler used to do the preparation for destruction of the credit card companies. All the people he met during the trip referred to him as Tyler. Marla also is seen to refer to Jack as Tyler. She even gets confused and ends up having an affair with both of them. This shows that most probably the two personalities having have merged into one body are inseparable and unidentifiable (Palahniuk 16). Fight Club as a movie exhibits a number of film techniques. Suspense as a technique is used in the movie at the place when the narrator is not given a name at the start of the mov ie. In this case, the viewer does not fully understand the position of the narrator. Finally, it comes out that he is the main character and suffers from failure of identity (Ringrose 92). This again brings up another film technique of symbolism. The disorder affecting the narrator that leads to lack of identity makes the narrator not be given a name. Suspense is created at the place when

Prions Essay Example | Topics and Well Written Essays - 1500 words

Prions - Essay Example Clinical signs among others include personality changes, psychiatric problems, lack of coordination, steady gait, involuntary jerking movements, unusual sensations, insomnia, confusion and severe mental impairment in the later stages. Those known to infect other vertebrate animals include scrapie in sheep, bovine spongiform encephalopathy (BSE) in cows, chronic wasting disease in American elk and deer, transmissible mink encephalopathy in mink and feline spongiform encephalopathy in cats (Jeffrey, Goodbrand & Goodsir 1995). One of the primary risk factors identified in relation to prion diseases is age. Studies suggest that a general mechanism might produce the remarkable reduction in disease risk as age increases. For example, in a study of scrapie outbreaks, it is observed that incidence of clinical cases peaked in sheep with age ranging from 2 to 3 years. The same age range has been noted in cattle with mad cow and deer with chronic wasting disease (Heisey 2004). In terms of its prevalence in the human population, it is estimated that 1 in 10,000 people are infected with CJD at the time of death. The actual prevalence of prion diseases are very difficult to ascertain due to overlapping symptoms that may lead to misdiagnosis. (Heaphy 2003) Research pertaining Research pertaining to prion diseases is deemed limited by the fact that studying them is substantially hampered by the unconventional properties of the presumed etiologic agent. Moreover, the long incubation period ranging from 34 to 41 years ("Mad cow could be dormant in people" 2006) of the diseases make them more difficult to detect. Moreover, the standard laboratory methods utilized for studying viruses and bacteria may not be applicable in this case (Belay & Telling). However, following reports of the outbreak of BSE, commonly termed as "mad cow" disease, in many European countries coupled with the estimated economic and medical implications of the said epidemic, the scope and nature of research on prion diseases has developed rapidly. This paper focuses on the current advancements in the study of prion diseases specifically in terms of modes of transmission, diagnosis methods, possible treatment and prevention. Modes of Transmission The manner of transmission of prion diseases is of primary concern in view of the protein nature of the prions. Note that unlike other types of infectious diseases which are spread by microbes, prion diseases are caused by misshaped protein, dubbed as prion protein, which transmits the disease between individuals causing brain deterioration (Belkin 2003). Based on recent studies, prion diseases have been considered unique as these can be inherited, sporadically occur or spread through infection. Majority of the prion disease cases are said to occur spontaneously, hence, animals with no prion protein mutation were observed infected. (Collinge 2001) On the other hand, inherited prion disease occurs in animals carrying a rare mutant prion allele. The disease is transmitted when healthy animal consume tainted tissues of other infected animals. The "mad cow" epidemic has been attributed to this mode of transmission as practice of feeding the cattle with processed remains of other cattle, which may have been infected already, became common. (Weissmann 2004) In humans, as in the cases of CJD, the

The intrusion system designed with the help of classification technique is the popular ones as it provides more security to the systems in which it is installed. The classification technique is used to classify the type of attack the system faces. (Base 2000).The intrusion system has the responsibility of protecting the system and preventing the attacks. According to Mun the intrusion detection system works well only if the system is selected based on the type of network. The intrusion detection system must be selected to suit the network. There are various types of networks and the system must make sure that it satisfies the network's requirements. The classification technique is used in the intrusion systems to classify and divide the attacks and threats. (Mun 2009).This technique is preferred by most of the network administrators due to its compatibility and efficiency. The intrusion systems work well only when the network's requirements are satisfied. The intrusion detection systems are generally classified into network based intrusion detection systems and host based intrusion detection systems. Network based intrusion system makes use of classification technique since it offers more protection when compared to the other techniques. The systems which are built using classification technique protect each layer of the network. The Ethernet of IP and the other layers are protected and they can be free from intruders. (Northcutt, Noval 2003).Since the classification technique based intrusion detection systems
