Chloride is actively transported across the skin of
the intact
leopard frog, Rana pipiens.
The influx and efflux in 0.2 mM NaC1
are 0.67 and 0. 72 μeq/10 g-hr, respectively.
The renal efflux of
chloride is 0.02 μeq/10 g-h .
The transepithelial potential differences (TEP) range from -1 to +32...
This study evaluated the potential of the aerobic Mycobacterium strain JS6O to grow on a variety of organic acid substrates, and the possible effects an organic acid would have on the degradation rate of vinyl chloride (VC). A series of batch growth tests were designed to determine the time it...
Chloride containing fertilizers are used to reduce the severity of take-all root rot of wheat in western Oregon and appear to reduce nitrification in moderately acid soils. Objectives of this study were to determine if nitrification is inhibited by the Cl ion, increasing soil solution ionic strength, or changes in...
Take-all root rot (caused by Gaeumannomyces graminis var.
tritici, Ggt) is one of the major diseases limiting winter wheat
yields in western Oregon. Losses caused by take-all (TA) can be
significantly reduced through crop management and fertilization
practices.
Results from field experiments in western Oregon show that the
use of...
A gas-permeable-membrane-supported (GPMS) biofilm consisting
of methylotrophic bacteria was effective in degrading chlorinated
methanes, ethanes, and ethenes. The biofilm was developed on a
gas-permeable fabric (Goretex, W.L.Gore & Associates, Elkton,
Maryland) that divided a reactor vessel into a liquid compartment
and a gas compartment. Goretex is a nylon-backed teflon mesh...
Specimens of Citharichthys stigmaeus, the speckled sanddab,
were taken from Yaquina Bay, Newport, Oregon and exposed for
eight days to dissolved measured concentrations ranging from 2.9
μg/l to 190 μg/1 of the polychlorinated biphenyl, Aroclor® 1260.
Oxygen consumption was measured to determine any change from
routine levels of respiration. This...
Performing bridge inspections can be a very daunting task for every department of transportation (DOT) in the country. Because the leading cause of deterioration in reinforced concrete bridge decks is corrosion of the steel reinforcement, the ability to detect the concentration of corrosion-causing chlorides in the concrete, using a non-destructive...
Production of calcium chloride (CaCl2) and aqueous ammonia (NH4 +) from the ammonia chloride (NH4Cl) stream in the Solvay process was studied using an Ammonia Recovery Tower to produce 29 wt % aqueous ammonia and 40 wt % CaCl2 from the process feed stream or the tower bottoms stream. OLI,...
