Shapefiles can be viewed with a number of freely available applications, such as ArcGIS Explorer (which requires the .NET framework or Silverlight) or ArcReader ...

It describes the development of a new influenza vaccine at the Jenner Institute. Traditional influenza vaccines prime the adaptive immune system against the hemagglutinin (HA) and neuraminidase (NA) proteins (the H and N ...
