By an Arnold cell technique, the diffusion coefficients of propanol
and methanol in mixtures of air and argon system have been determined.
The carbon tetrachloride-air system was also studied to verify
the reproducibility of the experimental method.
The diffusion coefficients were compared with experimental
values when available and with values...
The binding of eleven polycyclic, aromatic hydrocarbons to the acid
form of poly A has been investigated. The hydrocarbons were chosen to
test a size criterion. Model building showed that some hydrocarbons
could intercalate in the helix and be well protected from contact with
the aqueous solvent. Experimentally it was...
The microbial composition of Pacific oysters (Crassostrea gigas)
subjected to UV-treated seawater was determined by quantitative and qualitative means. A total of 2,779 microorganisms were identified from seawater and oysters during a 72 hour sampling period employing a computer assisted replica-plating technique. UV treatment effectively eliminated coliforms and Pseudomonas Type...
