Exploration and production of oil in the Gulf of Mexico has seen an astonishing increase since the first well was drilled in 1936. Much of the current exploration is occurring in waters greater than 5000 feet. The largest and most unprecedented oil spill in the United States occurred on April...
Frost injury is one of the major factors limiting potato production in many parts
of the world. It would be desirable to transfer the frost-tolerance traits from the hardy
relatives to the cultivated potato, however, progress has been very slow. Since Solanum
commersonii has been the major source of frost...
Tomato [Lycopersicon esculentum Mill.] plants are chilling sensitive and do not
naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress
protectant in plants. While GB can increase tolerance of tomato plants to salt and
drought stresses, its effect on chilling tolerance has not been examined. To evaluate
whether...
Two types of parallel computers commonly used or solving large scientific problems are clusters of workstations and distributed-memory multicomputers. Each system has strengths and weaknesses for this task. Workstation clusters have a high performance to cost ratio and the advantage of the latest processors. Workstations are commonly under-utilized and can...
The purpose of this study was to ascertain the factors which
influenced undergraduate students in the School of Education at Oregon
State University to select vocational teacher education as their
major. Data were collected from 315 vocational, practical arts, and
non-vocational undergraduate teacher education majors who were
enrolled in teacher...
Crested wheatgrass (Agropyron cristatum [L] Gaertm), an introduced bunchgrass, has been seeded on over 5 million hectares of degraded rangeland in western North America because it establishes more readily than native bunchgrasses. Because crested wheatgrass stands are associated with native species displacement and low biological diversity, there is substantial interest...
Despite Portland’s progressive reputation, the response of city officials, police officers, and the community as a whole to the killing of the black man, Lloyd Stevenson, in 1985 at the hands of Portland police, demonstrates that the long racially discriminatory history of Oregon shaped public policy and popular thought about...
The Maya of Mexico and Central America pursue multiple livelihood approaches, relying primarily on natural resources obtained from the rainforest. Fishing in the many water bodies of the region is one among many livelihood opportunities, but its relative importance has not been assessed previously. Indeed, there remains an overall lack...
Fall-sown barley will be increasingly important in the era of climate change due to higher yield potential and efficient use of water resources. Resistance/tolerance to biotic and abiotic stresses will be critical. Low temperature is an abiotic stress of great importance. Resistance to barley stripe rust (incited by Puccinia striifomis...
