This study was conducted to investigate the accumulation of dietary polychlorinated biphenyls (PCB's) by a Mt. Shasta strain of rainbow trout (Salmo gairdneri). A commercial mixture of PCB's (Aroclor 1254) was added to the diet at a level of 15 ppm on a dry weight basis. Accumulation of PCB's was...

The excitation and decay probabilities for resonance scattering
of radiation from an atom with two coupled excited states and one
ground state in an external static field are calculated as a function
of time and frequency. Various oscillatory behaviors are found in all
the probabilities. These oscillations depend on the...
The generation of the methyl group of methionine, and is also involved in thymidylic acid and purine biosynthesis. The understanding of the mechanisms and controls involved in one-carbon metabolism is incomplete, and is complicated by the existence of conjugated folate cofactors containing up to seven glutamic acid residues. The information...
The cities of Corvallis and Philomath, Oregon,
have, over the last three decades, grown both spatially
and in numbers of people. This study examines the
attractions and constraints to growth between the two
cities. The most notable constraint to growth is the
fact that the soils in the study area...
