Survey Of Terrestrial Macro-Invertebrates Hg Content And Assessment Of Low Level Hg Presence On Human Health, Gregory Mansour
Survey Of Terrestrial Macro-Invertebrates Hg Content And Assessment Of Low Level Hg Presence On Human Health, Gregory Mansour
Senior Honors Projects, 2010-2019
Forest ecosystems in the Shenandoah Valley of Virginia are not directly exposed to major sources of Hg contamination. Rockingham Co was assumed to be suitable as a low-level control in comparison with sites exposed to major industrial contamination in Waynesboro VA for studies in the late 1900’s. Subsequently the presence of low level Hg from background sources has been demonstrated. This study was conducted from 2014-2016 and expanded from two sites in to four sites in 2016. A composite air index, soil, and decaying organic material “duff” were analyzed for total THg concentrations using a Perkin Elmer Flow Injection Spectrophotometer …
The Effect Of Ambient Temperature On Recovery Of Surgical Stress In Sprague-Dawley Rats, Romie D. Powell
The Effect Of Ambient Temperature On Recovery Of Surgical Stress In Sprague-Dawley Rats, Romie D. Powell
Masters Theses, 2010-2019
Laboratory animals are housed at ambient temperatures ranging from 20°C – 26°C per recommended guidelines. Rats in particular typically prefer ambient temperatures (Tamb) of ~27°C (Brown et al, 2011). When rats undergo surgical instrumentation for experimental use, they often recover at normal room temperature (~21°C). While this is comfortable to those maintaining them, it may lead to a cold thermal stress for the rats. It is hypothesized that housing rats at ambient temperatures away from their preferred Tamb could lead to a thermal stress, which adversely affects surgical recovery. To address this, rats (220g-350g) were surgically instrumented with a radiotelemetry …
