Inbreeding of the avirulent physiologic race 8 strains of Ustilago hordei was
purported to have increased its pathogenicity in a stepwise manner that led to a highly
pathogenic race, designated race 14. The analysis of electrophoretic karyotypes and
restriction fragment length polymorphism profiles detected with a telomere-specific probe
(TelomereRFLP) in...
Ventenata dubia L. (ventenata) is an introduced, winter annual grass that has recently been raising concerns across the Pacific Northwest Bunchgrass Prairie and the Palouse Prairie. It is well established now in pasturelands, croplands, and a variety of ecosystems including grasslands, sagebrush steppe, ponderosa pine forests and woodlands. Ventenata is...
Photoelectric and Compton interactions are some of the common interaction mechanisms we observe when gamma radiation interacts with matter. These interactions are highly depended on the energy of the radiation and the atomic number of the detector material. Lower the energy of the photon and higher the atomic number of...
Northern highbush blueberry is a long-lived perennial crop that is well adapted to low soil pH conditions. The plants are often shallow rooted and absorb primarily the ammonium (NH₄) form of nitrogen (N) rather than nitrate-N (NO₃-N). Traditionally, commercial blueberry fields have been irrigated with overhead sprinklers and fertilized using...
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...
This dissertation focuses on the behavior of security returns around certain events that occurred in the Saudi stock market. In the first study, we measure and analyze the reaction of security returns around a major horizontal merger that occurred in the banking industry in Saudi Arabia. The objective of this...
Changes in lifestyle over the last century have resulted in a dramatic increase in the incidence of diabetes in the United States (U.S.). Mexican-Americans, the largest Hispanic/Latino subgroup in the U.S., are 1.7x’s as likely to have diabetes as non- Hispanic Whites. Culturally appropriate approaches for treating diabetes in minority...
