Processing of laser interferometric signals for small displacement measurements

Creator:: Peng, Gwo-sheng
Abstract:: Algorithms for analyzing laser interferometry signals were developed and adopted to the computer based processing of small displacement measurements. These methods, matrix operation approach and fixed parameters approach, are based on signal phase calculation and are able to replace complex fringe counting electronic circuits. The matrix operation provides an approach...

The effects of thinning on stand and tree growth in a young, high site Douglas-fir stand in western Oregon

Creator:: Marshall, David D.
Abstract:: The Levels-of-Growing-Stock Studies in Douglas-fir is a regional cooperative to investigate the effects of levels of growing stock on young stand growth. The Hoskins installation, in western Oregon, was established in a dense, high site natural stand at total age 20 years. The initial thinning resulted in an immediate 131...

Factors affecting semen quality and their effects on the fertilizing ability of broiler breeder spermatozoa using a fluorometric assay

Creator:: Bootwalla, Salim Mohsin
Abstract:: Three distinct studies using an ethidium bromidedigitonin fluorometric assay were conducted to determine if the fertilizing ability of individually caged broiler breeder males (BBM) could be enchanced by nutrition, breeding and semen extender viscosity. The first study evaluated the effects on the spermatozoal quality of BBM by feeding corn-soybean meal...

Duration and rate of grain filling and subsequent grain protein content in selected winter wheat populations

Creator:: Mou, Beiquan
Abstract:: The lack of information regarding the inheritance of the duration and rate of grain filling, and the possible relationship between grain fill and grain protein content in wheat prompted this study. Early maturing Chinese cultivars, 'AI Feng 2' and 'CB 83-52', and late maturing cultivars adapted to Oregon, 'Stephens' and...

A production function analysis of water resource productivity in Pacific Northwest agriculture

Creator:: Holloway, Milton L.
Abstract:: The competition or rivalry for the use of water resources among economic sectors of the Pacific Northwest and among geographical regions of the western United States has intensified in recent years. This rivalry and the long run prospects for water shortages have increased the demand for research concerning the productivity...

Characteristics of Northern squawfish (Ptychocheilus oregonensis) and feasibility for utilization as human food

Creator:: Lin, Dongdong
Abstract:: The characteristics of Northern squawfish (Ptychocheilus oregonensis) and the feasibility of utilization of this species for human consumption were investigated. In the first experimental phase, the iced storage characteristics of squawfish were determined. Quality changes were monitored over 24 days of storage by chemical, physical, microbiological and sensorial methods of...

A model for understanding the influence of selective and nonselective harvest on fish populations

Creator:: Hirai, Takayuki
Abstract:: To understand the influence of selective harvesting on the adaptive capacity of fish populations in changing environments, a computer simulation model was developed. In the model, hypothetical populations were composed of five different life histories, which were genetically determined. Each life history type had its own rate of survival and...

Evaluation of combining ability in mosquitofish

Creator:: Pongthana, Nuanmanee
Abstract:: Two replications of a half dial lei cross experiment were performed among four inbred lines of mosquitofish, Gambusia affinis. These inbred lines originated from three random-bred stocks: OR, TX and CD. The experiment was conducted as a completely randomized design. Experimental material consisted of parental lines and F₁ populations maintained...
