The objectives of this research were to determine the effects of various soil parameters on the reaction of Isopropyl-N-(3-chlorophenyl)Carbamate (CIPC) with a soil and to relate enthalpy values for the adsorption to chemical or physical bonding mechanisms. Six Oregon soils providing a range of pH, organic matter, clay, iron oxide,...
The genome of the nuclear polyhedrosis virus which infects the
larvae of the tussock moth, the lepidopteran, Hemerocampa
pseudotsugata, was isolated, identified as deoxyribonucleic acid, and
characterized in terms of its physical and biological properties. An
isolation procedure for the viral DNA was established which consisted
of the following steps:...
Eleven species of Mononchidae Chitwood, 1937 were
found among the nematodes separated from 48 soil samples
in Thailand and sent to Oregon State University. Six
species are newly described and illustrated including
Iotonchus bangkokensis, Iotopchus ainostomos, Iotonchus
chantabunensis, Iotonchus ravonqensis, fotonchus thai-Iandensis, and Miconchus triodontus. Also reported is a

Research was conducted in a mixed-coniferous forest stand
that was clearcut, burned, and seeded in order to study early plant
succession, grazing influences on native and introduced species, big
game use, and environmental relationships vegetation, animal,
and environmental research was carried out from 1965 to 1967 in
three, five-acre exclosures...
4-Pyridoxic acid is the major metabolite of all forms of
vitamin B₆ in mammalian species. The determination of 4-pyridoxic
acid, therefore, is important in the investigation of vitamin B₆
metabolism and for the establishment of human requirements for the
vitamin.
Although 4-pyridoxic acid is itself fluorescent, Huff and
Perlzweig (1944)...
Steroid carbenes have been investigated as synthetic intermediates.
Basic decomposition of 4-en-3-one tosylhydrazones (and
other A-ring systems) gives varying amounts of 2, 4-dienes, and
solvent derived products with diglyme, heptane, tetrachloroethylene,
carbon tetrachloride, benzene and cyclohexene. A method for
separating complex product mixtures was developed and a study of
the...
