Pulse reader for ionization chambers

Creator:: Boothe, Gary F.
Abstract:: A pulse reader for ionization chambers has been developed, tested, and calibrated. An insulated gate field effect transistor (IGFET) was used to detect the pulses and Victoreen Model 362 Pocket Chambers were used as ionization chambers. The energy dependence of the Victoreen Model 362 Pocket Chamber was determined to be...

Corn (Zea mays L.) yields as influenced by nitrogen, row spacing and intercropped ryegrass (Lolium multiflorum)

Creator:: Wivutvongvana, Paibool
Abstract:: Two field corn experiments were conducted on a Woodburn silt loam soil near Corvallis, Oregon, in 1972-1973 to investigate the effects of certain soil management practices on the yield and performance of corn (Zea mays L.). Experiment I involved variables that included three corn row spacings (76, 114, and 152...

Driving simulation : a mechanism for understanding driver response to mobile barriers in work zones

Creator:: Swake, Joshua
Abstract:: Highway construction projects require temporary changes in roadway characteristics, such as the number of operational lanes, lane path, lane width, shoulder width, and posted speed limit. These modifications which are often temporary in nature have the potential to impact driving performance. Many research efforts have focused on developing standards to...

A study of morphological variation within Pseudoroegneria spicata (Pursh) A. Löve (Poaceae: Triticeae)

Creator:: Carlson, Jack R.
Abstract:: Chromosome counts were determined for 152 accessions of Pseudoroegneria spicata (Pursh) A. Löve and, combined with existing count data, used to plot the distribution of diploid and tetraploid populations. Morphological variation of 55 characters was examined in five groups totaling 205 operational taxonomic units (OTU's), using cluster, principal factor, and...

Experimental and mathematical procedures for the estimation of shelf-life : application to temperature-abused chilled seafood

Creator:: Almonacid-Merino, Sergio Felipe
Abstract:: The validation and potential use of mathematical models to estimate the shelf-life of refrigerated food exposed to temperature abuse and basing such estimations on microbial growth was analyzed. Combined heat transfer, microbial growth models, and non-parametric statistical procedures formed a computer-based predictive tool to assess shelf-life and estimate the accuracy...

Organizational responses to drug use in the workplace : a study of Oregon manufacturing companies

Creator:: Thayer, Brock E.
Abstract:: This study investigated the prevalence of workplace drug prevention programs with regards to employee drug policies, drug testing, and employee assistance programs in a sample of Oregon manufacturing companies. The objectives of the study included: 1) identifying the contributing factors that supported the decision to implement or not implement a...

Performance of partially and fully anchored wood frame shear walls under monotonic, cyclic and earthquake loads

Creator:: Seaders, Peter
Abstract:: The objectives of this study were to evaluate the performance of wood frame shear walls under monotonic, cyclic and earthquake loads by: (1) estimating the variability of shear wall performance, (2) comparing the performance of walls under each loading protocol, (3) evaluating the effects of anchorage on wall performance, and...

Evaluation of the limit number effects for reduced inspection in ANSI/ASQC Z1.4 using a Markov model

Creator:: Grinde, Roger B.
Abstract:: ANSI/ASQC Z1.4 is a widely used attributes acceptance sampling system. A necessary aspect of a scheme, from both a theoretical and psychological viewpoint, is the switching between normal, tightened, and reduced inspection as a function of quality history. In the latest revision of the standard the switching rules were altered...

An Ecological Assessment of a Potential Sea Otter (Enhydra lutris) Reintroduction to the Oregon Coast

Creator:: Kone, Dominique
Abstract:: Sea otters (Enhydra lutris) used to exist along coastlines throughout much of the North Pacific Ocean. During the Maritime Fur Trade, sea otters were extirpated from much of their historic range, including Oregon. There is renewed interest in reintroducing sea otters to Oregon. Managers seek improved understanding of the potential...

The performance of wood frame shear walls under earthquake loads

Creator:: White, Kevin Bradish DelGrande
Abstract:: The overall goal of this study is to evaluate the earthquake performance of wood frame shear walls, and more specifically: (1) to compare the performance differences of fully and partially anchored walls under monotonic, cyclic, and earthquake loads, (2) to compare wall performance under earthquake loads with that of standardized...
