The Miridae, or plant bugs, associated with noble fir, Abies
procera Rehd., are discussed. Thirty six species of the Miridae were
collected from noble fir. Twenty five of these species are considered
only "visitors" to noble fir. The study does not deal with these
species. Noble fir is a host...
The purpose of this study was to determine if thinning, fertilization or a combination of thinning and fertilization had an effect on overall average specific gravity, modulus of elasticity, modulus of rupture, fiber length and intra-ring characteristics. Material for this experiment consisted of 7 trees randomly selected from each of...
Replication of plasmid molecules containing either a left-end or a
right-end adenovirus origin was investigated. When the plasmids were
linearized to expose their respective adenovirus termini, mixed, and
transfected with helper adenovirus DNA into the human 293 cell line, a
new molecule was detected. The new molecule was the size...
Studies were conducted to investigate the metabolism of
selenium (Se) , and the influences of Se on the metabolism of cadmium (Cd) and inorganic mercury (Hg) in rats, and in ram semen in
vitro. Se-deficient (-Se) or Se-adequate (+Se) rats were injected intraperitoneally with either ¹⁰⁹CdCl₂ (5 μCi/rat) or ²⁰³HgN0₃...
The purpose of this research was to test the effectiveness of
the ethnographic method as a tool for evaluating nontraditional
adult and continuing education programs. The program evaluated was
the Oregon Heritage Festival, a four-week Summer Term activity
designed to eclectically draw upon the arts, humanities, and science
to illustrate...
Alzheimer's disease, a chronic and irreversible form of
dementia, has been recognized as one of the most critical
medical-social-economic problems facing our country. As
Alzheimer's disease and other related dementias progress,
the patient becomes increasingly dependent upon family and
natural support systems to provide care. This dependency
can place the...
I. The Effect of Artificial Photoperiod on Eating Behavior and Other
Behavioral Observations of Dairy Cows.
Twenty-eight cows were randomly assigned to a dairy photoperiod of
18 h light and 6 h darkness or to continuous light and observed 1 d each
month from December 1981 to February 19.82. Lighting...
The semi-arid regions of the Pacific Northwest are
characterized by a high degree of annual temperature and
precipitation variation. As a result of this climatic
variation, dryland nitrogen fertilizer trials on fallow-
,wheat rotations typically demonstrate a variable response.
Wheat growers in the area must not only cope with this...
Chalkbrood is a mycosis of larvae of the alfalfa leafcutting bee,
Megachile rotundata (Fabricius). It is a serious threat to alfalfa seed
growers in western North America who use populations of this bee for
pollination. Basic studies were conducted to determine the etiology of
this disease and the course of...
