Diversity and community structure of aquatic insects in isolated montane desert streams

Creator:: Bogan, Michael T.
Abstract:: Local aquatic insect diversity and community structure is the result of multiple local and regional factors, and observed patterns depend upon the spatial and temporal scale under examination. Isolated stream systems in arid regions represent a new challenge in understanding the drivers of diversity and community structure, as most studies...

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...

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...

Expression of Follicle Stimulating Hormone (FSHβ) and its Receptor (FSHR) within the Ovine Placentome

Creator:: Wu, Eleas M.
Abstract:: Follicle stimulating hormone (FSH) plays a key role in the ewe’s estrous cycle but understanding its continued importance during pregnancy is not well understood. Researchers have proposed a model theorizing that a cascade of hormones is responsible for pregnancy maintenance. Weems et al. proposed a model for placental progesterone production;...

Life History of the Northern Rubber Boa (Charina bottae) in Oregon

Creator:: Leppin, Mark V.
Abstract:: The Northern Rubber Boa (Charina bottae) is a small, secretive boa native to the Pacific Northwest. Despite this being possibly the highest latitude boas and one of only two boas native to the continental U.S., it has received surprisingly little attention. Most of the research on the natural history of...

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...
