This report presents tables of suspended-sediment data collected from 1956 to 1967 at 10 sites in the Umpqua River basin. Computations based on these data indicate that average annual suspended-sediment yields at these sites range from 137 to 822 tons per square mile.
Because available data for the Umpqua River...
A set of circuit analysis programs designed for the IBM 1620
computer (having 40,000 digits of memory) is described and its operation
is explained. The set consists of d-c, a-c, and transient analysis
programs.
The d-c and a-c analysis programs provide the branch current
and node-to-reference potential for linear circuits....
This report includes information concerning experimental use of unregistered pesticides or unregistered uses of pesticides. Experimental results should not be interpreted as recommendations for use. Use of unregistered materials or use of any registered pesticides inconsistent with its label is against both Federal Law and State Law.
Studies were conducted to determine the extent and nature of
sub-lethal effects of herbicides on plant growth. At least one
herbicide from each major chemical class of herbicides was evaluated
under greenhouse conditions. Oat plants were grown in sand
culture to eliminate soil interferences. Herbicides were applied
pre-emergence in nutrient...
Due to the scarcity of information concerning the oxidase systems
in cranberries the peroxidase, catalase, and polyphenolase systems,
which are used as biochemical indexes of adequacy for enzyme inactivation
in other fruits and vegetables, were investigated.
Enzyme extracts were prepared from acetone powders with and
without phenol-binding agents such as...
The role of beta-carotene degradations in the development of
off-flavors in milk and milk products has not been established. The
purpose of this investigation was to study the oxidation of beta-carotene
and to identify volatile compounds arising from autoxidizing
beta-carotene.
Pure cyrstalline beta-carotene, mixed with Celite to accelerate
oxidation, was...
