Chlamydiae encode a family of proteins named the polymorphic membrane proteins, or Pmps, whose role in infection and pathogenesis is unclear. The Rockey Laboratory is studying polymorphic membrane protein expression in Chlamydia abortus, a zoonotic pathogen that causes abortions in ewes. C. abortus contains 18 pmp genes, some of which...
This study is an economic analysis of enrollment demand for
graduate education at Oregon State University as well as in the United
States. For the analysis of Oregon State University data on new
graduate enrollment, data were obtained for 27 academic departments
with 10 observations per department. The most important...
The objectives of the current study were 1) to evaluate the nutritional composition of chicken breast meat labelled as organic and non-organic, and 2) to determine the effect of microalgae and methionine supplementation on meat quality, the incidence of white striping, and muscle pathology in broilers. Two experiments were conducted...
This contribution employs a „fish chain‟ approach or ocean to plate analysis to examine key market drivers affecting Northern Gulf cod fisheries recovery since their collapse in the early 1990s. Drawing upon the backward bending supply model of fisheries; secondary data was compiled and analyzed for the pre- and post-collapse...
A series of trials was conducted with Polypay (P), Coopworth
(CP), Hampshire (H), and crossbred ewes over a two year period at three
locations to assess the effects of ewe body condition and pre-lambing
supplementation on ewe productivity. Supplementation trials were
conducted at all three locations in Year 1 using...
A simulation study of end-of-aisle order picking AS/R systems
is made with special emphasis on improving the system throughput by
introducing a zone near the home (Input/Output) location on each side
of the aisle, for storing partially picked pallets. The study considered
class-based-turnover assignment policies, one with a zone and...
Digitally controlled switching DC-DC converters have recently emerged as an attractive alternative to conventional switching converters based on analog control techniques. This research focuses on eliminating the issues associated with the state of the art switching converters by proposing three novel control techniques: (1) a digitally controlled Buck-Boost converter uses...
The Bear Creek area is situated at the boundry between the Basin and Range Province, Deschutes Basin and Blue Mountains Province. It contains rock units representing most of the Cenozoic geologic column. The major rock units exposed are the Clarno Formation, John Day Formation, Columbia River Basalt Group, Deschutes Formation...
