Most irrigation water in Oregon is of excellent quality. Occasionally a deep well yields water that is too salty for irrigation, or contains constituents that are detrimental to plants or soils. Water can be of poor quality for irrigation because of the amount of impurity (salt) it contains or the...
A high-resolution numerical model with idealized topography is used to investigate the degree to which a coastal upwelling jet separates from the shelf as it flows around a submarine bank depending on the wind strength and the horizontal scale of the bank. Experiments were run using several wind forcing magnitudes...
Stakeholders in the southern Blue Mountains have reported a need for a scientific review of the northern goshawk (Accipiter gentilis atricapillus; hereafter, goshawk) in relation to dry forest restoration and management activities. Here, we provide a compilation of relevant synthesis papers, existing peer-reviewed research, and goshawk monitoring efforts in the...
Hop (Humulus lupulus L. var. lupulus) is grown worldwide for the production of the dried female inflorescence (strobulus), or cones, used principally for the bittering and flavoring of beer. Information is scant on the inheritance of traits of economic importance in hop, and present knowledge is based on historical data...
Hop (Humulus lupulus L.) is a perennial, dioecious species in which the female inflorescence (cones) are harvested and used in the beer-brewing process to impart bittering and/or flavoring to beer. Hop breeders have typically utilized clonal selection and hybridization to develop new cultivars. The use of genetically diverse parents for...
Hop (Humulus lupulus L.) is cultivated for the female flowers, or “cones,” which traditionally have been used as a bittering and flavoring agent in beer. Hop breeding historically relied on relatively simple selection techniques within established breeding lines. Supplementing current breeding material with new genetic sources would enhance a hop...
Metal–insulator–metal diodes with Nb₂O₅ and Ta₂O₅ insulators deposited via atomic layer deposition are investigated. For both Nb₂O₅ and Ta₂O₅, the dominant conduction process is established as Schottky emission at small biases and Frenkel–Poole emission at large biases. Fowler–Nordheim tunneling is not found to play a role in determining current versus...
Central Oregon is the primary U.S. hybrid carrot seed production area, supplying seed to the domestic fresh market carrot industry. Approximately 85 percent of the hybrid carrot seed planted in the United States is grown
in Jefferson and adjoining counties. The Madras and Culver areas support most of the carrot...
