This thesis describes a control tool for managers of a
Broiler Breeder Farm, a farm which raises chickens for the purpose
of fertile egg production. It presents the development of
a simulation of a Broiler Breeder Farm which uses a deterministic
step by step process to generate expected values of...
Oregon White Oaks (Quercus garryana) were once abundant in the Willamette Valley, Oregon, but have drastically decreased because of fire suppression, agriculture, and human development. Oaks are an important ecosystem because they provide a diverse habitat for bird species that are insectivorous and/or cavity nesters. We studied the oak restoration...

Experiments were carried out in fall and winter, 1990
and spring and summer, 1991 , to determine growth and
mortality of juvenile Pacific oysters {Crassostrea gigas)
in effluent from cultured coho salmon {Oncorhynchus
kisutch) , and effluent from salmon in which the red
macroalga Palmaria mollis was cultured. Ambient sea...
Mycobacterium vaccae JOB5 and Graphium sp. were studied to evaluate their ability to cometabolize methyl tert-butyl ether (MTBE) and its metabolites after growth on two different alkanes, propane and iso-pentane. Both cultures were capable of cometabolizing MTBE and the metabolites, tert-butyl formate (TBF) and tert-butyl alcohol (TBA). MTBE, TBF, and...
Plant form is a compromise between resource gathering, reproduction and
the tolerance to physical demands of the abiotic and biotic environment. In
an agricultural field in addition to the natural factors causing stress, humans
also introduce physical and mechanical stresses, and chemical pesticides
into the environment. Many of these factors...
In current prosthetic practices, the design process heavily relies on the prosthetist’s expertise and the limited methods to quantify design choices. This thesis investigates the lower-limb prosthetic fitting process and the importance of the socket design. Previous research has taken local stiffness of the limb to provide prosthetists with more...
An improved extraction (2.5% HPO₃, 5 mM dithiothreitol) and HPLC quantification using a C-18 column at 35°C and 0.1M acetic acid (98%) and acetonitrile (2%) mobile phase was developed to quantify total ascorbic acid (AA) in commercial whole/semi-skim/skim raw/pasteurized/UHT milk packaged in opaque bags, transparent plastic, cardboard, and Tetra Brik™....
In eukaryotes, ARGONAUTE proteins (AGOs) associate with microRNAs (miRNAs), short interfering RNAs (siRNAs), and other classes of small RNAs to regulate target RNA or target loci. Viral infection in plants induces a potent and highly specific antiviral RNA silencing response characterized by the formation of virus-derived siRNAs. Arabidopsis thaliana has...
