متن کاملCoupled aquifer-borehole simulation.
A model coupling fluid hydraulics in a borehole with fluid flow in an aquifer is developed in this paper. Conservation of momentum is used to create a one-dimensional steady-state model of vertical flow in an open borehole combined with radially symmetric flow in an aquifer and with inflow to the well through the wellbore screen. Both laminar and turbulent wellbore conditions are treated. The i...
متن کاملPlasmid-mediated mineralization of naphthalene, phenanthrene, and anthracene.
The well-characterized plasmid-encoded naphthalene degradation pathway in Pseudomonas putida PpG7(NAH7) was used to investigate the role of the NAH plasmid-encoded pathway in mineralizing phenanthrene and anthracene. Three Pseudomonas strains, designated 5R, DFC49, and DFC50, were recovered from a polynuclear aromatic hydrocarbon-degrading inoculum developed from a manufactured gas plant soil s...
متن کاملYeast sulfate-reducing system. I. Reduction of sulfate to sulfite.
X35-APS-This substrate was synthesized from S%ulfur trioxide-pyridine complex and AMP by a method similar to that of Baddiley et al. (13) except for simplifications and modifications necessary for introduction of label. An alternat,ive method has been described by Reichard and Ringertz (14). Approximately 3.7 me of S35-HzS04 was dried at 80” in a reaction tube fitted with a ball joint and side ...
متن کاملMicrobial Ecology Changes in Organic Matter Biodegradability Influencing Sulfate Reduction in an Aquifer Contaminated by Landfill Leachate
In situ experiments were conducted to measure sulfate reduction rates and identify rate-limiting factors in a shallow, alluvial aquifer contaminated with municipal landfill leachate. Single-well, push–pull tests conducted in a well adjacent to the landfill with 98 mM dissolved organic carbon (DOC) exhibited a sulfate reduction rate of 3.2 mmol SO4 _2 (L sediment) _1 day _1, a value in close agr...
