The biology and behavior of the alkali bee Nomia melanderi Cockerell (Hymnoptera: Apoidea)

Creator:: Hackwell, Glenn Alfred
Abstract:: Nomia melanderi Cockerell is one of the most efficient pollinators of alfalfa in Eastern Oregon. Emergence begins in June, usually reaches its peak in early July, and may continue into early August. Male emergence precedes female emergence by four or five days. For the first few weeks of this time,...

Effects of temperature and other abiotic and biotic factors on development and survival of the immature stages of the alfalfa leafcutting bee, Megachile pacifica (Panzer) (=rotundata (F.)) (Hymenoptera:Megachilidae)

Creator:: Undurraga O., Jaime M.
Abstract:: Larval mortality of leafcutting bee, Megachile pacifica (Panzer) (= rotundata (F.)), is high, usually exceeding 50%. Parasites and predators are not a limiting factor in the survival of the progeny. The disease chalk brood has been an important mortality factor since 1974. Inadequate food supply, pollen and nectar, may affect...

Some factors influencing carbon dioxide production by Leuconostoc citrovorum

Creator:: Holmes, Beverly Ann
Abstract:: This study was undertaken to determine the role Leuconostoc citrovorum may play in carbon dioxide production in milk. The ability of L. citrovorum strains to produce gas was studied by two methods. A qualitative method used visual measurement of gas where an agar plug was forced up the neck of...

Simulation of postdiapause development of the western cherry fruit fly, Rhagoletis indifferens Curran, and its application to predicting the time of adult emergence

Creator:: Stark, Steven Bruce
Abstract:: Air temperatures and soil temperatures at the surface, two inches, and four inches under a grass cover were recorded over a 93 day period. These data were used along with other temperature data from bare soil in the construction of three sets of models for the prediction of maximum and...

Dynamic control of brushless doubly-fed machines

Creator:: Zhou, Dongsheng, 1964-
Abstract:: This thesis presents the development of dynamic control strategies for the brushless doubly-fed machine (BDFM). A simple open-loop scalar controller is first investigated and its response is found to be oscillatory. Using the speed feedback signal, an improved closed loop scalar control algorithm is designed. Steady state performance is controlled...

Evaluation of instream flow restoration targets and the carrying capacity of Oncorhynchus mykiss according to temperature, Whychus Creek, Deschutes Basin, Oregon

Creator:: Jones, Lesley M.
Abstract:: The Pelton Round Butte Hydroelectric Project (Oregon) was built between 1957 and 1964. As a result the anadromous steelhead trout was extirpated from the upper Deschutes Basin by 1968. The Deschutes Basin is a model for instream flow restoration projects in the Pacific Northwest that are largely driven by the...
