especially in America. Many associate the virus with our former president Franklin Delano Roosevelt (FDR)‚ who was bound to a wheelchair due to his diagnosis of poliomyelitis. “Poliomyelitis is a debilitating muscle disorder‚ caused by the enterovirus known as the poliovirus” (Khan Academy‚ 2015). There are three serotypes of the virus that can cause paralysis; “poliovirus is a positive-strand single-stranded RNA virus” (Racaniello‚ 2005). This virus is transmitted through human to human contact

Virus Attack Prevention Based on Hulme (2004) article‚ many companies are now using firewalls‚ antivirus software and intrusion detection systems‚ but hackers and worms still break through business systems and cause serious damage. Lately it seems that more and more prevention and protection is required. Based on the article‚ attacks such as Blaster‚ MyDoom‚ and Witty cost businesses more than ten billion dollars a year. There is a need for more intelligent shields to ward off new attacks as they

The PET scan‚ or Positron Emission Tomography‚ was born in 1973 at Washington University. It was created by Edward Hoffman‚ Michael M. Ter-Pogossian‚ and Michael E. Phelps; Phelps is most often credited with the invention (History of PET and MRI‚ 2009). In preparation for a PET scan‚ radioactive tracers are injected into the body‚ inhaled‚ or ingested by the patient through a solution that they drink. Then the scan will actually begin‚ as the patient lies on a table‚ which glides into the machine

Ping Sweeps and Port Scans January 11‚ 2013 Freddie Jackson DeVry University This report is to provide insight on nefarious computer activities called ping sweeps and port scans as a request from management. I will identify them‚ explain what they are use for‚ how they are used and how to stop them from attacking a network. Finally I will discuss how they can be eliminated as security risk. The information in this report is designed to increase the understanding and knowledge of these two

The Influenza virus kills about 36‚000 people a year. The Influenza virus is a potentially deadly virus that attacks the respiratory system. It also leaves the human body very tired and weak. The Influenza virus mostly affects the respiratory system. The basic structure of the Influenza virus includes the Viral Envelope‚ Nucleoprotein (RNA)‚ Neuraminidase (Sialidase)‚ Hemagglutinin‚ and the Capsid. When the virus attacks the respiratory system‚ it causes fatigue‚ fevers‚ and chills. Ironically

Avian Influenza‚ also known as the bird flu‚ is a virus that primarily infects birds. In rare cases‚ can this virus affect humans in a way that is harmful. There are three forms of the Avian Influenza which are: H5‚ H7‚ and H9 viruses. The H5 virus has circulated Asia and the Middle East in about 16 different countries worldwide. It mostly affected these countries because they have this bird species within range of human contact. The H7 virus is a type that is very uncommon in humans‚ unless they
