This study of the Oregon State college news appearing in the Oregonian and Oregon Journal in Portland at five-year intervals over a 15-year period was undertaken primarily to attempt to determine, if possible, trends in college news; to indicate the emphasis on different types of college news; to determine the...
Agricultural tile drainage is one of the major causes of increasing nitrate (NO3-) concentrations in surface water bodies thanks to the usage of nitrogen fertilizers and manure. Denitrifying bioreactors are constructed at the edge of agricultural lands in order to remove NO3- from drainage water through labile carbon substrates intended...
Denitrifying bioreactors are an edge-of-field treatment technology particularly well suited for nitrate removal from subsurface (tile) drainage effluent of agricultural lands. The effectiveness of a proposed denitrifying bioreactor is site-specific and depends upon the complicated interplay of field and environmental parameters controlling discharge events, nitrate concentrations, subsurface temperatures, dissolved oxygen...
In this research, a model system for studying the effects of the toxic metabolite, methylglyoxal, was created using Chinese Hamster Ovary (CHO) cells which produce tissue plasminogen activator (t-PA). The human gene for glyoxalase I was subcloned into an inducible mammalian expression vector. This vector was then used to create...
Intracellular signaling cascades can no longer be viewed as linear pathways that relay and amplify information. Often, components of different pathways interact, resulting in signaling networks. The interactions of different pathways and the dynamic modulation of the activities of the components within signaling pathways can create a multitude of biological...
Shewanella oneidensis MR-1 is a gram-negative, facultative anaerobic bacteria with the capability of dissimilatory metal reduction. The ability of the organism to reduce a wide range of solid metal-oxides during anaerobic respiration makes it an ideal candidate for the powering of microbial fuel cells (MFCs), which capture the electrons discharged...
Microbial electrochemical systems (MESs) have attracted much research attention in recent years due to their promising applications in renewable energy generation, bioremediation, and wastewater treatment. In a MES, microorganisms interact with electrodes via electrons, catalyzing oxidation and reduction reactions at the anode and the cathode.
The bacterial community of a...
