Principles Of Radioisotope Methodology, Gary Rothwell

Honors Theses

This honors project was designed for familiarization with modern instrumentation and experimentation methods for radioisotope detection and energy calculations. The two main instruments I studied were the Geiger-Mueller Counter and a single channel pulse height analyzer. This report will include a brief history of radiation and a description of the more important types. Next is a description of the two instruments mentioned and some simple experiments I conducted using them.

Hemorrhagic Component Of Northern Copperhead Venom, David Hill

Honors Theses

The major hemorrhagic component of northern copperhead (Agkistrodon contortrix mokasen) venom was partially purified by ion exchange and molecular sieve column chromatography. TAME and Phospholipase enzymatic activities were shown to be unrelated to hemorrhage. BAEE and procoagulant activities appear to be associated. Hide powder activity seems to correlate with hemorrhagic activity. Both show metal and disulfide dependences.

The northern copperhead, (Agkistrodon contortrix mokasen) is commonly found in forests from Massachusetts to Illinois, and in highlands as far south as Georgia and Alabama.

The venom of the northern copperhead has been reported to contain several en- zymatic activities as well as …
