Direct current conductivity measurements on KC1:O[superscript]= crystals
were used to determine an enthalpy of 0.42 ev for the dissociation for
anion-vacancy-oxide ion complex.
The entropy of dissociation was
found to be approximately -4x 10⁻⁴ev deg⁻¹. The intrinsic "activation" energy was found to be 1.91 ev as compared to 1.95 ev,...
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...
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...
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,...
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...
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...
