Certain factors affecting colonization of Ponderosa pine by Ips confusus (Leconte) (Coleoptera : Scolytidae)

Creator:: Pitman, Gary Boyd
Abstract:: The purpose of this study was to study in some detail host factors which influence the population dynamics of bark beetle. The dissertation objectives were to ascertain the applicability of utilizing osmotic pressure values and relative turgidity values of phloem tissue as indicators which reflect upon the physiological profile of...

The effect of light intensity on Douglas-fir foliage quality : survival and development of Western spruce budworm

Creator:: Waddell, Karen L.
Abstract:: Foliage from Douglas-fir(var. glauca) seedlings grown under two light intensities was bioassayed to examine palatability to the western spruce budworm (Choristoneura occidentalis Free.). Samples were collected in Fall, Winter and early Spring to identify seasonal changes in host foliage, as evidenced by the response of spruce budworms. Fall collected foliage...

Factors influencing nest success of greater sandhill cranes at Malheur National Wildlife Refuge, Oregon

Creator:: Ivey, Gary L.
Abstract:: I developed a priori hypotheses and used logistic regression to model Greater Sandhill Crane (Grus canadensis tabida) nest success in relation to weather, habitat and management variables for cranes breeding at Malheur National Wildlife Refuge (MNWR) in southeast Oregon. My primary interest was to investigate the effects of habitat conditions...

Solving polynomial equations from 2000 B.C. through 20th century

Creator:: Farea, Hussain A.
Abstract:: This paper is divided into two parts. The first part traces (in details providing proofs and examples) the history of the solutions of polynomial equations(of the first, second, third, and fourth degree) by radicals from Babylonian times (2000 B.C.) through 20th century. Also it is shown that there is no...

The anthelmintic activity of SCH 32481 (netobimin[superscript R]) against gastrointestinal nematodes in cattle and sheep and Fasciola hepatica in sheep

Creator:: Richards, Laura S.
Abstract:: The efficacy of a new broad-spectrum anthelmintic, Netobimin[subscript R] (coded SCH 32481-Schering Corporation) was evaluated in two trials conducted during either the spring or fall grazing seasons of 1984 in Western Oregon using 20 cross-bred yearling beef heifers and 30 cross-bred spring lambs, respectively. Percent efficacies were determined in both...

A survey of linear programming algorithms

Creator:: Maurer, Roger J. (Roger Joseph), 1962-
Abstract:: Linear programming is a recent development in the field of Mathematics having its origin in the past seventy-five years. The purpose of this study was to identify several methods for solving linear programming problems. The algorithm for each of the methods is described in detail along with an analysis of...

Responses to fertilization and fish stocking in the pelagic ecosystem of a naturally fishless lake

Creator:: Cameron, William A.
Abstract:: Ecologists have studied the responses of pelagic ecosystems to varying levels of nutrient loading and fish predation on many different scales ranging from small experimental enclosures to whole lake systems. There are recurring patterns of response to these two variables, which are generally predictable on the basis of biogeographic, behavioral,...

Cell cycle regulation of DNA precursor accumulation in the yeast Saccharomyces cerevisiae

Creator:: Koc, Ahmet
Abstract:: In budding yeast, many of the genes that encode enzymes required for DNA precursor synthesis (MCB genes) are expressed under cell cycle control in late G1/S. The relationship between MCB gene expression, dNTP synthesis and DNA synthesis was investigated by using α factor-synchronized Saccharomyces cerevisiae. The levels of all four...
