An analysis of 4,385 recoveries of mallards (Anas platyrhynchos), that were reported during the years 1929 to 1972, was made to determine the migrational characteristics and survival rates of
mallards banded at Malheur National Wildlife Refuge in southeastern Oregon. Two populations, a transitory population and a wintering population, were banded...
A study was conducted to determine the quantity and character
of substances leached from logs floating in water, and the rate of
leaching of these substances. The species of wood studied were Douglas
fir and ponderosa pine. The research was carried out in a controlled
laboratory environment with log sections...
A series of log storage experiments were conducted to determine
whether leachates derived from water storage of logs are acutely
toxic to fish. Log segments approximately 18 inches long and 16 inches
in diameter were stored in tanks and held submerged for a period of
7 days. The holding water...
This study involved the use of the two-choice preference test to determine the taste reactions of buck and doe Columbian black-tailed deer (Odocoileus hemionus columbianus) to ascending concentrations of water extracts of Douglas fir, red alder, cascara, western hemlock and bitterbrush; to an ethanol extract of Douglas fir, and to...
A frozen concentrate (>10⁹ cfu/ml) of a human strain of Lactobacillus
lactis (strain MLC) was fed to swine. Bottle feeding resulted
in reduced fecal coliform counts and incidence of scouring in nursing
pigs. In one group of pigs treated 54 days, the Lactobacillus to coliform
ratio was 1280:1; in the...
With the advancing solid-state technology, it is necessary to
develop new techniques for synthesizing digital networks. The regular
pattern of cellular circuits seems to be the best fitted for the new LSI
technology. Recently, cellular implementations of comibinational circuits
have received considerable attention but very little attention has
been given...
This report presents observations from two programs in 1975, WISP and UP-75 to study circulation off Oregon. WISP was a study of the transition between the winter and spring regimes, and UP-75 was designed to determine whether there is a poleward undercurrent along the continental slope during the upwellinq season....
Real-time predictive voltage control of a direct-current (d-c)
generating system is achieved with the aid of a hybrid computer.
Some assumptions were required to adequately simplify the simulation
of the d-c generating system.
A predictive controller is used to maintain the load voltage of
the d-c generating system (the controlled...
