Experimental and modeling studies of canopy radiation and water use efficiencies, soil respiration and net ecosystem carbon exchange.
(2002)
Canopy radiation and water use efficiencies (RUE and WUE), soil respiration and interannual availability in net ecosystem carbon exchange (NEE) are important issues in global climate change study. This thesis summarized ...
Responses of a tallgrass prairie to experimental warming.
(2002)
I also examined the potential responses of C and N processes to elevated temperature. The results suggest that there was a time lag between the response of peak aboveground biomass (AGB) and that of net N mineralization. ...
Mechanism of cellular intoxication by large clostridial toxins.
(2002)
Clostridium sordellii lethal toxin (TcsL) is a large clostridial toxin (LCT) that glucosylates Ras, Rac and Ral. In chapter II, using a suite of inhibitors, steps in cell entry by TcsL were dissected and entry appears to ...
The reduction of uranium by sulfate-reducing bacteria in the terrestrial subsurface and a pure culture bacterium.
(2002)
The microbial reduction of uranium was investigated in a contaminated aquifer and with a pure culture model organism, Desulfovibrio vulgaris Hildenborough. The concentrations of Fe(III), U(VI), nitrate and sulfate were ...
Cytosolic delivery of mutant forms of toxin B from Clostridium difficile facilitates characterization of the intracellular activities of large clostridal toxins.
(2002)
Clostridia are gram-positive spore-forming organisms responsible for a variety of diseases in both humans and animals Three species of Clostridia- Clostridium difficile, Clostridium sordellii and Clostridium novyi- produce ...
