Methods of Determining Porosity and Spatter Losses of Arc Welds

The original objective of this project was to determine the effect of varying current intensity and electrode coating composition upon the spatter losses and porosity of arc welds made by alternating current. This subject was suggested by the Welding Research Council of the Engineering Foundation, which is a clearing house for welding research in order to avoid du­plication of work.

Mouse in the House: Deer Mouse and Sin Nombre Virus Dynamics in Montana

Sin Nombre virus is a strain of Hantavirus that causes the sometimes fatal human illness Hantavirus Pulmonary Syndrome. The reservoir host of SNV is the deer mouse. Deer mice are found in a wide variety of habitats including peridomestic (in and around buildings) settings. Amy provides an overview of hantaviruses and discusses the research she has been conducting on the SNV/deer mice system since 1995 (in Arizona) and 1999 (in Montana).
