Partial purification of cathepsins from salmon muscle

Creator:: Ting, Chao-Yun
Abstract:: Cathepsins are intracellular proteinases that hydrolyze the peptide bonds of proteins. These enzyme have been implicated in the tenderization of aging beef, with the deterioration of radiation-stabilized meats on storage, and in the spoilage of fish prior to processing. Hence, the cathepsins of edible muscles are of concern to the...

Forb Community Response to Various Disturbances in the Pacific Northwest Bunchgrass Prairie

Creator:: Watson, Brogan L.
Abstract:: Observed declines in native pollinator species worldwide has generated concern and focused research into the disturbances, past and present, which may have contributed to these losses. In grasslands, for example, habitat degradation and fragmentation from historical and current crop production and livestock grazing has left only a few remnants of...

Influence of veneer roughness, lathe check, and annual ring characteristics on glue-bond performance of Douglas-fir plywood

Creator:: DeVallance, David B.
Abstract:: Current lathe technology, smaller diameter logs, smaller core diameters, and the sale of higher grade veneer for use in engineered wood products are all factors contributing to plywood manufacturers using rougher veneer with different lathe check characteristics. When rough veneer is encountered, plywood manufacturers typically increase the adhesive spread rate...

Improvement of barley utilization through feed processing or supplementation

Creator:: Wilson, Jerry James
Abstract:: Methods to improve the efficacy of swine barley rations were evaluated. A literature review pertaining to the subject, three feeding trials involving 104 swine, and a laboratory investigation were used in the study. The effects of pelleting with a new modified pellet die that produces a dense pellet; supplementation with...

Reproductive characteristics of two breeds of swine fed dichlorvos

Creator:: Trindade, Roger James
Abstract:: Thirty-six gilts were used in an experiment of 2³ factorial design. The experiment consisted of two breeds (Yorkshire- Berkshire and Yorkshire), two feeding regimens (pre-breeding and post-breeding) and two levels of dichlorvos (2, 2-dichlorovinyl dimethyl phosphate, 0 and 800 mg. per gilt per day). Pre-breeding treatment consisted of feeding dichlorvos...

Rapid evolution of post-transcriptionally regulated RESTORER OF FERTILITY-LIKE genes in the genus Arabidopsis

Creator:: Jogdeo, Sanjuro
Abstract:: The Pentatricopeptide Repeat (PPR) gene family produces RNA-binding proteins that target organellar transcripts. The PPR family is expanded in land plants, with nearly 450 genes identified in Arabidopsis thaliana. In plants with a Cytoplasmic Male Sterility (CMS) phenotype, members of the PPR family can act as a RESTORER OF FERTILITY...

Evaluation of crumb rubber modified mixtures using performance based analyses

Creator:: Saxton, Robert W.
Abstract:: This study investigated the laboratory performance of crumb rubber modified mixtures compared to a standard bituminous mixture using performance based test procedures. This study was part of an asphalt resurfacing program for the Seattle Washington area. Laboratory analyses were used to estimate the long term pavement performance of these mixtures...

An evaluation of the cubic autotape under dynamic conditions

Creator:: Plasker, James Robert
Abstract:: Accuracy requirements for positioning a vessel in the near shore area have increased in recent years. To meet these requirements several electronic positioning systems have been developed. One such system is the Cubic Autotape Model DM-40. The Autotape is a circular positioning system which utilizes the phase comparison between transmitted...

Constructed wetland treatment of fecal coliform in dairy pasture runoff

Creator:: Osborn, Erik C. J.
Abstract:: A constructed wetland receiving pasture runoff from a dairy in Tillamook, OR was monitored during the winter of 1997-98 in order to estimate coliform treatment efficiency during winter high flow periods. Monitoring occurred during four sampling periods, each lasting 2 to 4 days. Samples were taken every two hours from...

Reproduction and growth of the Pacific basket-cockle, Clinocardium nuttallii Conrad, from intertidal and subtidal environments of Netarts Bay

Creator:: Ratti, Frank Douglas
Abstract:: Age structure and growth of shells of the Pacific basket-cockle, Clinocardium nuttallii in Netarts Bay, Oregon, were investigated with special emphasis on the differences between subtidal and intertidal populations. The cockle was chosen for study because its growth is highly sensitive to physical factors in the environment. Evidence is presented...

Transport and transformations of nitrogen compounds in effluent from sand filter-septic system draintile fields

Creator:: Bushman, Jennifer L.
Abstract:: A total of 44 intermittent sand filter-septic systems, in five counties of Western Oregon, were sampled over a three-month period during the summer of 1995. The sand filter systems varied in age from 36 months up to 167 months (3 to 13.9 years). Liquid samples were taken from the septic...

Influence of spacing and crown recession on wood quality of intensively-managed young-growth Douglas-fir

Creator:: Robbins, James M.
Abstract:: Intensive management of young-growth Douglas-fir plantations has emphasized volume growth over wood quality. A better understanding of the variables that affect wood quality is needed so that wood quality and stand yield can be systematically combined into a silviculture program. This experiment utilized two separate experiments to establish the relationship...
