Hens were artificially inseminated at 8:00 a.m., 4:00 p.m.
and 11:50 p.m. Fertility was found to be significantly lower after
8:00 a.m. inseminations than after 4:00 p.m. or 11:50 p.m. inseminations
for 2 to 6 days, 2 to 9 days and 10 to 17 days following inseminations.
Slightly higher fertility...
Studies were conducted with Indian River "Hybro" broiler chicks
and Oregon Agricultural Experiment Station dwarf and normal White
Leghorn hens to improve the utilization of white western wheat. Chick
studies were primarily concerned with characterizing the growth
inducing properties of an antibiotic fermentation residue (Vigofac)
which had shown a greater...
My work on computing complex catalyzed organic transformations reveals that only a few subtle chemical factors, e.g. non-classical hydrogen bonding, (hyper)conjugation and steric effects, common across different catalyst manifolds are critical for catalysis and selectivity. Rational manipulation and exploitation of these factors has led to improved catalyst designs, which has...
This study compares the requirements of three forest certification systems, the Sustainable Forestry Institute (SFI), the Forest Stewardship Council (FSC), and the International Organization for Standardization (ISO), with the 2005 McDonald-Dunn Forest Plan Revision. The analysis was done with a series of matrices comparing the requirements of SFI and FSC...
Environmental toxicologists and public health officials are responsible for assisting in the identification, management, and mitigation of public health hazards. As a result, there is a continued need for robust analytical tools that can aid in the rapid quantification and characterization of chemical exposure. In the first research phase, we...
One hundred and fifty-one weanling rats of both sexes were fed
control diets or diets containing 160 ppm diethylnitrosamine (DEN) or
150 ppm N-2-fluorenyl-acetamide (FAA). The carcinogen level was
calculated so that the LD₅₀ should be achieved at about 17 weeks.
Each carcinogen treatment was incorporated with three different diet...
Purpose of the Study:
The purpose of the study was to determine the characteristics
of existing secondary school advisory committees and the effects
that these groups have on local vocational programs which they
serve. The major purpose of this study was to ascertain, through
statistical analyses, the degree to which...
The Afghan public higher education (HE) system absorbs less than one-fifth of government education spending and per student spending declines, while the student annual enrollment is rising. This contrast may trigger challenges and inevitable tradeoffs for the public universities to
encounter. Policies concerning the diversification of financing stream need attention;...
The objectives for the use of the Oregon State
University college forest include providing both facilities
for research and teaching, and providing funding through
timber harvest. The older age-classes of the forest are
valuable for attaining both objectives. The opportunities
and costs of removing acreage in the older age classes...
A teacher may say, "I have twenty years of experience,"
but just what does it mean? This study suggests explanations
for the meaning of "Experience," not by looking at the number
of years in a classroom, but at what teachers did in those
years that could make the teaching experience...
