Resource Planning and Management (RPM) techniques have been
applied in this study of a product-mix and production scheduling linear
programming problem of a cooperating food processor.
Resource Planning and Management is a graphical portrayal of
the interactions between related resources and activities within a
system. In this study linear RPM...
Eggs, larvae and adults of the four subspecies of Hy la regilla
occurring in Oregon as given by Jameson, Mackey and Richmond
(1966) were collected and subjected to salt stress in a series of
graded seawaters.
It was found that in all cases adults were more tolerant than
larvae and...
The Washington Cooperative Fishery Unit at the College of Fisheries, University of Washington, Is carrying on studies of fishes in Lake Washington as part of the International Biological Program sponsored by
the National Science Foundation. One of our interests Is. in the effects of temperature on the movements of fishes...
The theoretical aspects and fabrication techniques of
a new surface field-effect transistor were investigated.
The new MOS-transistor uses a three-layer structure
similar to those found in bipolar transistors. The new MOS
structure introduces an impurity gradient in the channel
region of the transistor and also makes it possible to reduce...
The studies to be reported herein were initiated following a cursory search of the literature concerning the lakes of the State of Oregon. Few substantive lirnnological works were located. More detailed efforts added only a few obscure references. Since change is the basic axium of ecology, there was concern for...
The fish and wildlife resources of the Middle Coast Basin (Fig. 1), their present status, value, limiting factors and water requirements are reviewed in this report. Minimum and optimum stream flow recommendations are presented and field study methods outlined.
The flow recommendations for fish life are primarily for use by...
A mathematical model was developed that relates the
ratio, R, of two light flux measurements to the mass concentration,
m, of the atmospheric aerosol particles between
a source of parallel light (e.g., the sun) and the measuring
system. R is defined as the ratio of the light fluxes
passing through...
Partly laminated sediments on the upper continental
slope (200-600 m) off central Peru contain a diverse assemblage
of fish debris, diatoms, and the remains of a variety
of other nektonic, planktic, and benthic organisms. Approximately
97 percent of the fish scales recovered from
the best preserved cores come from the...
The nature of the isoprenoid pathway and diversity of biologically
significant products suggests that the pathway may be highly regulated,
particularly under stress conditions, where the availability of high
energy intermediates is limited. It was postulated that germinating
seeds suffer from a limited supply of available energy and must therefore...
