Levels of ⁶⁵Zn in water, sediments, plants, and animals in
Alder Slough, a small ecosystem in the Columbia River Estuary,
were determined periodically during a one year period. Concentrations
of total Zn in organisms were also measured to permit
computation of specific activities (μCi⁶⁵Zn/g total Zn). Temporal
fluctuations in the...
Flexible aerodynamic surfaces have been shown to favorably influence flight characteristics at low Reynolds numbers by increasing lift, angle of attack at stall, and resistance to perturbation. The objective of the research presented within this thesis is to investigate the influence of two aspects of flight observed in biological flyers,...
In situ salinity, turbidity and temperature were measured at discrete depths and water samples for radioanalysis were simultaneously collected in the Columbia River Estuary using a specially designed instrument package. Particulate radioactivity was concentrated by filtration and the dissolved radioactivity by evaporation or ferric oxide bulk precipitation. Radioanalysis was by...
A liquid-extraction procedure for the concentration of zinc in
sea water was developed. The metal ion in sea water was chelated
with sodium diethyldithiocarbamate and extracted into an organic
solvent, methylisobutylketone, at the normal pH of sea water. A
back-extraction into HCl followed, providing a concentration of 30X
for the...
Lab notebooks with lengths and weights of tested samples. Includes capture dates, depths and dates samples went into detector. Date of coverage: 11/28/91 to 11/12/65.
This report covers somewhat more than a full year of operation.
Individual contracts between the AEC and Oregon State University covering
the research of William Pearcy, Andrew Carey, Jr. , and Charles Osterberg
were combined into a joint contract on 1 November 1964. No Progress
