Uncovering the mechanism of IL-4-mediated T cell survival

Creator:: Moscibrocki, Cathleen M.
Abstract:: Although IL-4 is a well-characterized multi-functional cytokine, its role as a survival factor in T cells is not completely understood. In an attempt to uncover IL-4-mediated survival, we studied caspase activation in primary mouse T lymphocytes undergoing death by neglect, activation-induced or steroid-induced cell death. Here, we identify the executioner...

Toxicity of some commonly used pesticides to Trioxys Pallidus and its establishment in filbert orchards of Willamette Valley

Creator:: Saeed, Mohammad
Abstract:: A parasitic wasp, Trioxys pallidus Haliday (Hymenoptera: Aphidiidae) was imported from Europe and initially released against the filbert aphid Mvzocallis coryli (Goetze) in hazelnut (filbert) orchards of the Willamette Valley, Oregon beginning in 1984. In the present study, I investigated the establishment rates of this parasitoid. A total of 13...

Detection and characterization of resistance to pesticides in codling moth, Cydia pomonella L. from Oregon

Creator:: Arshad, Muhammad, 1958-
Abstract:: Toxicological studies were carried out to evaluate the susceptibility of codling moth, Cydia pomonella L. to different insecticides. Bioassay procedures for adults and larvae were standardized in terms of posttreatment holding and temperature, age and sex of insects, insecticide formulations and selection of a reference strain. This study detected a...

Agonistic behavior in three species of Microtus (M. canicaudus, M. oregoni, and M. townsendii)

Creator:: Weil, James Wayne
Abstract:: Agonistic behavior among three species of Microtus live-trapped near Corvallis, Oregon was recorded in order to interpret habitat segregation by the species in areas of syrnpatry. The method used to measure agonistic interaction was similar to that of Colvin (1970). Agonistic behavior was recorded under red light in a neutral...

Development of a Structured Adaptive Approach to Klamath Basin Sucker Recovery Planning

Creator:: Barajas, Miguel F.
Abstract:: Listed as endangered in 1988, the Lost River sucker (Deltistes luxatus) and Shortnose sucker (Chasmistes brevirostris) were once abundant and widely distributed in the Klamath Basin in Southern Oregon and Northern California. Populations of both species have been declining since the late 1960’s. Factors thought responsible for declines include naturally...

Current-feedthrough cancellation technique for current-mode T/H circuits

Creator:: Young, David Y. W.
Abstract:: In this paper, an analysis of the clock-feedthrough effects in switched-current (SI)' circuits will be presented. The clock-feedthrough effects caused by the non-ideal characteristic of MOS switches when they are turned off limit the accuracy of the analog track-and-hold (T/H) circuits. A model to analyze and characterize this effect is...

Diversity combining ARQ over the m(> 2)-ary unidirectional channel

Creator:: Elarief, Noha
Abstract:: In diversity combining automatic repeat request (ARQ), erroneous packets are combined together forming a single, more reliable, packet. In this thesis, we give a diversity combining scheme for the m-ary unidirectional channel. A system using the given scheme with a t-unidirectional error detecting code is able to correct up to...

Hydrogen abstraction from substituted t-butylbenzenes

Creator:: Harvey, Robert Louis
Abstract:: A study of the relative rates of the alkyl hydrogen abstraction from a series of meta and para substituted t-butylbenzenes by the chlorine atom at 70°C has been carried out. Application of the Hammett equation yielded a ρ value of -0.44 for the para compounds. Possible explanations for the non-linearity...
