Grapevine red blotch virus (GRBV), the causal agent of red blotch disease (RBD) in grapevine, Vitis vinifera L., is an emerging pathogen of significance to the wine grape industry of Oregon, USA. To address knowledge gaps of GRBV epidemiology, spread of GRBV was evaluated in Oregon vineyards over four years....
Influence of abiotic and biotic factors were examined in selected
winter wheats previously identified as representing a range of
responses to septoria infection. In the greenhouse two and three
inoculations identified resistance when disease severity was assessed
either for the top four leaves or the flag leaf respectively. Kernel

Contrary to critics and scholars interested in the series’ therapeutic value, Harry Potter encourages post-9/11 subjects to neither heal nor mourn. Instead of taking up the potential pain and transformation in realizing and coming to terms with the deaths of his parents, Harry’s reattachment to the institution precludes his abilities...
This paper records a study of two quadratic number fields. In the first field, denoted by Ra[[square root] 11], the unique factorization theorem holds. In the second field, denoted by Ra[[square root] 10], it is demonstrated that the unique factorization theorem does not hold and therefore ideals are introduced to...
The cereal cyst nematode Heterodera avenae reduces wheat yield in the Pacific Northwest. Resistance and tolerance traits among spring wheat cultivars were poorly defined. Screening trials were conducted with 39 cultivars over a 2-yr period in irrigated commercial fields that were infested by H. avenae. Comparisons were made between drill...
