121: Linux Against Microsoft Windows
... almost impossible to write a virus for Linux because it must be 30-40 Mbytes.Also it has firewall system to protect the network from the hackers.If we think that there are a lot viruses for windows that can harm all of your system, we can understand how Linux is secure.Linux is a stable operating system that never fails like Windows.When Bill Gates presented the Windows 98, an ... irc softwares Mirc,Pirch and ICQ from internet. It is more secure to chat on Linux than Windows. You can not banned or nuked on Linux because there is a firewall in Linux and the viruses like trojan, that can harm your Windows system are not effective on Linux. These are the features for the users.There are also features for administrators. It is supported that a Linux system can be ...
122: Hemophilia Manitoba
... an internal bleed occurs or continuously through infusions. An infusion will stop the bleeding, but only for about a day. Therefore, most hemophiliacs infuse on a regular basis. Before 1985, infusions were not screened for viruses. This resulted in a major outbreak of the HIV virus that infected fifty percent of hemophilia patients. Also, hepatitis was transmitted throughout the hemophiliacs. Today, instead of human factor, recombinant DNA factor 8 is used in order to prevent viruses. People without insurance could not afford hemophilia. An annual bill for hemophilia is usually fifty to a hundred thousand dollars. Each unit for factor 8 is $1.50. In one particular case, surgery cost $500 ...
123: Genetic Engineering
... one of the projects they took smallpox, which has otherwise disappeared from the world, and found a way to genetically introduce into it, without reducing its efficacy as smallpox, either Ebola virus or equine encephalitis viruses. Nobody seems to know what happened to those experimental viruses. A third example: we now have plants genetically engineered to produce plastic. The idea is that we will no longer need to depend so much on petroleum, or on the Middle East for petroleum. The ...
124: Genetic Engeneering
... to make foods with high resistance to whether, temperature, pesticides, etc. therefore crop quality and amount grown would increase. Another area of genetic technology involves inserting genes into plants to make them immune to common viruses, this could increase the crop production. If the crop production could be increased, food would become cheaper and easier to obtain. For economical reasons gene technology is better for the producers and consumers. The producers ... relatively new and the full long term effects aren t known yet. Mr Bob Phelps from the Spokesperson for GeneEthics Network said Such foods are spliced from foreign genes from humans, animals, plants, bacteria and viruses, resulting in unpredictable permanent changes. Genetically engineered foods should be tested out thoroughly before they are marketed. As something could go really wrong. Growing genetically adjusted foods should not be allowed as it could cause ...
125: Factors Of Parasitic Virulence
... between sites of origin where the host and parasite were collected (Ebert 1994). Thus, the parasite was significantly more virulent in hosts it coexisted with in the wild than it was in novel hosts. Many viruses, such as Rabies (Lyssavirus spp.), persist in natural populations while maintaining high levels of virulence in all potential hosts (Krebs, J. W. 1995). Extinction is not an inevitable outcome of increased virulence (Lenski and May ... pp. 83-112 In Clinical Textbook for Veterinary Technicians, Second Edition. McCurnin, D. M. Ed. W. B. Saunders Company. Philadelphia. Childs, J. E., Mills, J. N., and Glass, G. E. 1995. Rodent-borne Hemmoragic Fever Viruses: A Special Risk For Mammalogists? Journal of Mammalogy. 76:664-680. Combes, C. 1991. Ethological Aspects of Parasite Transmission. The American Naturalist. 138:866-877. Ebert, D. 1994. Virulence and Local Adaptation of a Horizontally ...
126: Encephalitis
... There are many vaccines to prevent Encephalitis and some of the most common diseases in this topic are Measles, Mumps and Rubella, Meningitis, Japanese Encephalitis and Mosquito and Tic Bourne Encephalitis. Measles, Mumps and Rebella viruses are all associated with Encephalitis and all can be prevented with the same vaccine. Commonly known as the Measles vaccine it is administered by injection under the skin in the thigh or shoulder. Side effects ... received the Passive immunization I would also receive the Active immunization so it would be ready to work as soon as the Passive immunization ran out. Basically with Encephalitis there are many different forms of viruses that each have there own vaccines or protection. No matter what the side effect the vaccine or other protection gave me I would have to take it because there are really no other alternatives. I ...
127: Ebola Virus
... Ebola is a relentless killer. Ebola isn't publicized very much so it seems to be a wise topic to explore. This way others may be informed of one of the world's most powerful viruses. The purpose of this paper is to further educate all those interested in the powerful effects of the Ebola virus in its many forms. I. Introductory Statement II. History III. Variations IV. Prevention V. Transmission ... to deal with problems like overpopulation and poverty, we may end up looking back nostalgically on the late twentieth century as a time of health and tranquility. As we show you, in the world of viruses, we are the invaders (Baddorf, Ourworld.compuserve.com)." Between the years of 425BC-430BC Athens' population was dramatically reduced when about 300,00 of its inhabitants died from some sickness. Some people now believe that ...
128: Biological Warfare
... question remains, when will they attack? “It is highly likely that a terrorist group could threaten or attack Americans with germs within the next few years,” according to President Clinton. (Solomon) Biological warfare intentionally uses viruses, bacteria, fungi, or toxins from living organisms and death or disease in humans, animals, or plants. Fermentation can be used to produce such bacterial agents as anthrax, brucellosis, cholera, meloidosis, plague, q fever, or tularemia. Other viral agents are smallpox, cimean congo HF, rift valley fever, and vee. Use of these types of viruses and bacteria are becoming widespread in many areas of the world because they can affect many people efficiently and are cost effective. Biological weapons can ve traced back to Exodus when God placed the ten ...
129: Dna
DNA DNA, or Deoxyribonucleic Acid, is described, in Encarta Encyclopedia as a genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by ... a sequence of DNA nucleotides that specify the order of amino acids in a protein via an intermediary mRNA molecule. Substituting one DNA nucleotide with another containing a different base causes all descendant cells or viruses to have the altered nucleotide base sequence. As a result of the substitution, the sequence of amino acids in the resulting protein may also be changed. Such a change in a DNA molecule is called ...
130: Diabetes
... the environmental triggers are. One trigger might be related to cold weather. Type 1 diabetes develops more often in winter than summer and is more common in places with cold climates. Another trigger might be viruses. Perhaps a virus that has only mild effects on most people triggers type 1 diabetes in others. Early diet may also play a role. Type 1 diabetes is less common in people who were breastfed ... that followed relatives of people with type 1 diabetes, researchers found that most of those who later got diabetes had certain autoantibodies in their blood for years before. (Antibodies are proteins that destroy bacteria or viruses. Autoantibodies are antibodies 'gone bad,' which attack the body's own tissues.) Type 2 diabetes has a stronger genetic basis than type 1, yet it also depends more on environmental factors. Sound confusing? What happens ...
