In order to estimate wind turbine residL2;characteristics
in the presence of atmospheric turbulence, the important atmospheric
sources for the force excitations felt by the wind turbine system
must be identified and characterized. The goal of this research
is to develop the wind turbulence input model for horizontal axis
wind turbines....
Urinary steroids have been studied during early and late pregnancy in
domestic horses or sporadic samples at various stages of pregnancy in wild
equidae. In our studies, urinary estrone sulfate (E1S) and pregnanediol
glucuronide (PdG) were monitored throughout pregnancy in six pony mares by
enzyme immunoassay (EIA). Both hormones were...
Soil samples from the Mazama tephra deposit were collected
from the AC and C2 horizons at five different locations along the axis
of the main depositional lobe. The clay fraction from the samples
was recovered and studied by means of chemical, x-ray, DTA and
electron microscopy methods in order to...
Incubation experiments with an acid poorly drained soil have
shown that the application of neutral soluble salts influenced the level
of extractable Mn. The application of a salt which lowered the soil
pH either increased the extractable Mn or retarded the oxidation
and/or fixation of extractable Mn. This effect was...
Used Nuclear Fuel (UNF) contains transuranic (TRU) elements and numerous fission products as a result of the uranium fission process and neutron activation that occur in commercial light water power reactors. Recent environmental and nuclear proliferation concerns have spawned the development of advanced reprocessing techniques to close the nuclear fuel...
The development of new electronic devices and design procedures
applicable to ternary switching circuits suggests that it might be desirable
to use ternary arithmetic in direct digital control systems.
The advantages of decimal, binary, and ternary arithmetic in digital
computers are discussed and a set of rules for signed -digit...
Thirty-seven Yorkshire sows were bred to one of six boars; 34 of the sows were verified pregnant at 42 d of gestation. These sows were innoculated with ovine serum albumin (OSA) in Freunds' complete adjuvant at 65 d and later given a second injection in Freunds.' incomplete adjuvant 93 d....
As a group of promising semiconductor materials, metal chalcogenides in thin film form have been widely used in electronics and optoelectronics applications, such as solar cell devices and photon sensors. Unfortunately, the film size and product throughput are limited by the current vacuum-based thin film deposition techniques. Solution-based thin film...
A three-year investigation was conducted during 1980-1982 to
evaluate the potential of using herded sheep as a silvicultural tool
to suppress brush in Douglas-fir (Pseudotsuga menziesii) plantations
of Oregon's Coast Range. Sheep browsing of Douglas-fir was highest
in May soon after bud break. Averaged over the 2 years of grazing,...
