Anthrax :: viruses, diseases,vaccines

A minor scratch or abrasion, usually on an exposed area of the face or neck or arms, is infected by spores from the soil or a contaminated animal or carcass. The spores germinate, vegetative cells multiply, and a characteristic gelatinous edema develops at the site. This develops into papule within 12-36 hours after infection. The papule changes rapidly to a vesicle, then a pustule, and finally into a necrotic ulcer from Unlike chemical agents like Cyanide which disperse over time, Anthrax [spores] can survive in soil, water and elsewhere for as long as 40 years and is highly resistant to eradication. They can only be killed by steam sterilization or burning, but not by disinfectants. An infection of wild stock populations could follow a biological attack with spores. The infected animals could then pass on the disease to people. An Anthrax Vaccine does exist and it is at present produced under contract to the Department of Defense. The immunization consists of three injections given two weeks apart followed by three additional shots given at 6, 12, and 18 months. Annual booster injections of the vaccine are required to maintain a protective level of immunity. This particular method is effective when dealing with Anthrax contacted through the skin and is believed to be effective against inhaled spores in the case of a biological warfare attack. For those unvaccinated individuals, antibiotics like penicillin is known to lessen the severity of the illness, two million units every two hours administered intervenously It was formerly thought that inhaled spores are 100% fatal despite treatment but monkeys exposed to Anthrax spores have responded successfully to antibiotics, implying that antibiotic therapy may be useful in a biological warfare setting.

Evil Through Imagery It has been said for a long time that the only thing to fear is fear itself. It is easy to see that the boys become subject to their own illogical fears. In Lord of the Flies, by William Gilding, Imagery Is used to describe the Island and the characters themselves In dark and mysterious ways. Imagery Is also used as a way for the boys to create the beast and make it external as well as internal. There are several instances in the novel where people are described using ominous language. When Jack and his choir are seen for the first time they are scribed as a ;creature†¦ Room throat to ankle, hidden by black cloaks† (19). The choir's first Impression suggests that their purpose In the novel Is antagonistic In nature. Gilding's imagery automatically Identifies the characters In story that are associated with the more evil aspects of human nature such as fear and violence. Later in the novel, it seems that the older boys only become worse, with fear growi ng in them like an uncontrollable weed. It is noticeable when Jack starts disguising himself â€Å"[looking] in astonishment, no longer at himself but at an awesome stranger†¦ He face of red and white and black† (63-64).In his slow submission to fear, Jack Is becoming another person entirely from the boy who Initially crashed on the island and It Is shown literally here by him painting his face and changing his identity. The fear created on the island, in the form of the beast, is exposing Jack for what he really is, which is demonic and wicked in nature. Gilding uses imagery often to describe the malicious intent of characters throughout the novel, but he does not only describe characters in this way. The island on which the boys are stranded on Is meticulously described in the kook and most of the words used to Illustrate It are grim at best.When Gilding describes where Piggy and Ralph first find themselves, he describes the ground as â€Å"covered with coarse grass, torn everywhere by upheavals of fallen trees, scattered with decaying coconuts and palm saplings. Behind this was the darkness of the forest proper and the open space of the scar. † (9-10). Already, the island, though it has done no wrong, is becoming a canvas on which Gilding can paint his picture of doom and despair. Small things, such as this, are described assiduously through the inure novel.This Is used to give perspective and show cause to why the boys do what they do, among a variety of other things, the boys are reacting to their environment which is portrayed with no less than a vulgar light. When the boys go on their first expedition, which results in them pushing a boulder over, â€Å"the forest further down shook as with the passage of an enraged monster† (28). Gilding describes the devastation of the forest like this with a purpose, he is alluding to the fear that later controls the boys, or the beast. The disturbance of the peace from the the scar.Simple i tems on the island are portrayed much more villainous than they actually are for the purpose of showing what the boys have done to the island by corrupting it's innocence and peace with their naturally wicked human nature. The author makes use of both the image of characters and the setting of the island to show that humanity can turn anything into something foul, even a beautiful and untouched island. The imagery does not stop with the island and the characters, it also creates the very beast which leads to some of the characters downfall. When the twins first see he horrible beast they describe it as â€Å"furry.There was something moving behind its head-?wings. The beast moved too-? That was awful. It kind of sat up†¦ There were eyes-? Teeth-? Claws-?† (100). At this point in the novel, rational thinking has become scarce and is only really found in Piggy and Simon. Sam and Eric truly believe in what they saw and their grisly description only acts as a catalyst for th e other boys descent into madness from the fear. Since Simon is not effected by the illusion of the beast, he understands that the beast is not real but the Lord of the Flies corrects him â€Å"Fancy hinging that the Beast was something you could hunt and kill!†¦You knew didn't you? † (143-144). Gilding's imagery brought to life a character that is really Just the embodiment of the horror and destructiveness in the boys, revealing what the authors true beliefs about human nature are. Though, he does not seem to think that man kind is entirely uncontrollable. Simon is used as a beacon of hope and good intention. Simony's death is also very unique, using light imagery to state how Simon was the only light in the darkness all along. Towards the end of the novel, the beast comes very real, more than Just a figment of the boys wildest and darkest fears.In conclusion, imagery describes human kind's nature through the characters, the island, and of course the beast or fear in t he boys. The scary images used in the novel make it very easy to see why the boys went against each other in the end, proving that humanity is it's own worst enemy. Overall, the author's opinion about human nature influenced every facet of the novel and how it was written, but of course the most obvious expression of Gilding's opinion is seen in the imagery.

Advantages and Disadvantages of Online Graduate Study

Distance learning can be very convenient, but what about when it comes to graduate school? What are the online education advantages and disadvantages when it comes to getting a master or doctorate degree online? Is it better to attend graduate school traditionally? Does the online experience take away from your ability to gain valuable hands-on experience or networking experience? Online education is more common than ever. In fact, many educators and policymakers view online education as the wave of the future. There are also plenty of technology advancements, as well as hybrid in-person  and online programs, that allow students to learn in a hands-on way. Is an online graduate degree program right for you? Consider the pros and cons of an online graduate program before you choose one. Advantages Accessibility: Attend online classes from anywhere. This is great because many graduate school students hold down full-time jobs in addition to studying. Not having to rush to class on a busy workday -- or a relaxing weekend day -- can be a perk.Flexibility: Work on classwork when it makes sense for you, as you are not tied to a class schedule  in most cases.Interpersonal Breadth: Your peers will include students all over the country and even the world. This is also a great advantage for networking purposes.Cost: An online education does not require that you relocate to a new place or that you stop working full time.  Documentation: Documents, transcripts, live discussions, and training materials are all archived and recorded so that they can be retrieved via mail, e-mail or the schools website for reading, downloading and printing at any time.  Access: Instructors are available, respond quickly through email and generally are prepared to work with diverse students with a range of lifestyles and needs. Disadvantages   Employment:  If you attend an institution that is entirely online, you may find that you have to discuss the validity of your degree. Some people may not view a completely online program as being as authentic as a traditional or hybrid program. Information about the schools accreditation can convince employers of the programs validity.Communications: Most of your communication will be through email, which may not be the most effective method if you or the professor are better in person. You might miss the sound of an instructor or peers voice if there are no audio sessions.Courses: Not all courses of study are easily available online. If youre interested in a more unusual field, you may have difficulty finding a source for a complete online education.In-person responsibilities:  Hybrid programs in which you attend some classes in person, or do some projects in person, are valuable but the time needed to commute to school or participate in them can detract from work or family resp onsibilities.
