Concern about noise pollution has swept the country.
People are conscious of their environment and are trying to
preserve or to improve it. When the City of Lake Oswego
selected a site for their water treatment plant, they had
to assure the neighbors that it would not increase the
ambient...
The selenium-responsive syndromes and the discovery of
Factor 3-selenium focused attention on selenium in metabolism. Two
hypotheses have been advanced to explain the metabolic effect of
selenium: 1) substitution or sparing of alpha tocopherol, and 2) a
primary role in metabolism. The first hypothesis is supported by
Scott and Desai,...
Signification temperature differences were found to exist among three similarly situated stations in the Mid-Willamette Valley of Oregon. The stations were McMinnville, Salem, and Corvallis. Factors known to influence temperatures were compared with the temperature differences of the stations using available weather data. Factors examined included elevation, latitude, cloud cover,...
Diet, nutrition, and foraging strategies of canvasbacks (Aythya valisineria) and redheads (A. americana) were studied by collecting actively feeding birds throughout the reproductive season in 1980 and 1981; samples of available foods were taken each time a bird was collected. Nutrient composition of the aggregate diet was determined for each...

The thesis discusses stability of procedures based on linear
computing formulas for numerical integration of an ordinary first-order
differential equation. The theorems are proved: (1) If the
procedure is asymptotically stable it is stable for small positive step
size if the Lipschitz number is negative; (2) Relative stability always
exists...
A new procedure is developed for computing a root of algebraic equations with real coefficients and a degree n, where n is 2, 4, 6, 10, 14 or any positive odd integer. A heuristic procedure is added to partially lift the restrictions on the degree n. The procedures are written...
Traditional interpretations of James Joyce's Dubliners have often focused on the pervasive "paralysis" of the city, covered in the stories' range of "childhood, adolescence, maturity, and public life." However, these approaches have limited their focus on the women in the stories, often spotlighting the male characters--and the author--through a Freudian...
The effects of five tillage treatments on soil bulk density and
mechanical impedance were examined on Newburg sandy loam soil in the
Willamette Valley, Oregon, in 1987. Subsequent effects on seedling
emergence and yield of carrots (Daucus carota L., cvs. Orlando Gold
and Royal Chantenay) were also measured. Mechanical impedance...
Although studies have shown that some marine invertebrates
can obtain a portion of their nutrition from dissolved and nonliving
particulate organic matter, the relative importance of such foods in
their diet has not been established. The success of oyster hatcheries
could be significantly improved if the diet of living algal...

It is established folklore in numerical analysis, for solution
of a square system of linear equations by Gauss elimination, that the
standard method of choice of pivot elements is to search the entire
suppressed matrix for the element largest in absolute value. However,
it was felt by the author, that...
Nitrogen is a contaminant of niobium and tantalum adversely
affecting the workability of the metal. With recent interest in the

Ireland's Catholic Church played an important role in the turn-of-the-century nationalism that shaped James Joyce's identity and writing; yet it also played an important part in preventing that nationalism from achieving its goals of autonomy and cultural independence. For Joyce, this was particularly evident in the dialects and
thought structures...
The effects of deficit irrigations and nitrogen rates on the yield and size distribution of 'Detroit Dark Red' table beets were investigated during 1985 and 1986.
