Biotransformation of 2,4,6-trinitrotoluene by ruminal organisms

Creator:: De Lorme, Marthah J. M.
Abstract:: 2,4,6-Trinitrotoluene (TNT) has been the common munitions used in the world and is an environmental contaminant that is amendable to reductive transformation reactions. The rumen is an extremely reductive environment containing diverse microbial populations. There are 21 pure culture ruminal bacteria species in culture collection, these were tested for the...

Anaerobic biodegradation of the cyclic nitramines, RDX and HMX, by ovine ruminal microbes

Creator:: Eaton, Hillary L.
Abstract:: Cyclic nitramines released into all environmental compartments through anthropogenic activities are toxic and possibly carcinogenic and mutagenic. Soils on military ranges, located throughout the world in various climatic regions and close to human activities, are especially susceptible to cyclic nitramine contamination. The properties of soils on military ranges will directly...

Metabolism of pyrrolizidine alkaloids by ruminal microbes

Creator:: Hovermale, Jeannette Talbot
Abstract:: The plant Senecio jacobaea (tansy ragwort) produces several macrocyclic pyrrolizidine alkaloids which cause irreversible liver cirrhosis. All of the pyrrolizidine alkaloids in Senecio jacobaea are macrocyclic diesters of the necine base retronecine, with the two most predominant being seneciphylline and jacobine. Unlike horses and cattle, sheep and goats are generally...

Ruminal Biodegradation of Heterocyclic Toxic Compounds

Creator:: Tanaree, Dan D.
Abstract:: Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...

Metabolism of toxic plant alkaloids in livestock : comparative studies on the hepatic metabolism of pyrrolizidine alkaloids in sheep and cattle and of ergot alkaloids in an endophyte-resistant mouse model

Creator:: Duringer, Jennifer Marie
Abstract:: The pyrrolizidine alkaloids (PAs) and ergot alkaloids are known natural toxicants found in livestock forage. These alkaloids contribute to large economic losses in livestock throughout the world. An understanding of the mechanisms of toxicity and development of better diagnostic tools for better management practices was investigated. Variability exists in the...

Lead toxicity at various dosages in Naeemi lambs in Kuwait

Creator:: AL Sabbagh, Tariq Ashour
Abstract:: Environmental contamination along roadways with lead from processed petroleum and automotive residues has been reported. Toxicity to the herbivores grazing these areas has not been well studied. Comparison of lead concentrations adjacent to roads in Kuwait and in Oregon, USA was studied. Soil samples were taken from three sites at...

An historical review of Kolb's formulation of experiential learning theory

Creator:: Hickcox, Leslie K. (Leslie Kay), 1951-
Abstract:: The central purposes of this study were to review the historical sources of David Kolb's formulation of experiential learning theory, and to determine the effect and application of Kolb's theory and Learning Style Inventory as reflected in the literature between 1971 and 1990. It was found that Kolb based his...

A modeling study on downslope windstorms

Creator:: Smith, Craig M.
Abstract:: The generation mechanism for downslope windstorms was shown to vary according to inversion height and strength using a series of numerical experiments. Strong low level inversions were dominated by interfacial waves on the inversion, while high level inversion and cases without an inversion were dominated by internal gravity wave (IGW)...
