Biological control of spider mites (Acari: Tetranychidae) on grape emphasizing regional aspects

Creator:: Prischmann, Deirdre A.
Abstract:: During summer of 1998 and 1999, 34 and 10 vineyard sites, respectively, were sampled to assess spider mite pests and associated biological control by phytoseiid mites. Vineyards studied spanned five major valleys in western Oregon where grape production occurs. Leaf samples were taken from site perimeters and centers. One leaf...

OSU 360 : developing a virtual tour mapping infrastructure for Oregon State University

Creator:: Waggoner, Scott
Abstract:: Details the development of the OSU 360 virtual tour system (www.oregonstate.edu/osu360) from May 2008 to May 2009. OSU 360 is a collaboration between the Department of Geosciences, University Housing and Dining Services, Central Web Services, Web Communications, and Admissions/Enrollment. This article details the project development from determining goals, distinguishing locations,...

Plant growth regulators and shattering control in cool-season perennial grasses

Creator:: Lee, Suk-Kyun
Abstract:: Shattering is a natural phenomenon of floret and spikelet disarticulation across abscission layers of the pedicel and rachilla, respectively, after seed maturation. Seed shattering in cool-season grasses and native grass species is an economic problem in seed production. This study was conducted to determine whether the use of the plant...

Mineral assessment of open range livestock production on the Warm Springs Indian Reservation

Creator:: Brummer, Fara Ann
Abstract:: The Warm Springs Reservation is located in central Oregon. Livestock production consists of beef (commercial with an Angus, Horned Hereford base) and roping (Corriente and Longhorn) cattle and horses that forage most of the year on the open range within reservation boundaries. Forage consists of annual and perennial grasses and...

Design of a mechanically assisted dependent transfer mechanism for use on board commercial aircraft

Creator:: Gibson, Brenton D.
Abstract:: Business and recreation in the modern day world often include air travel as their cornerstone. Travelers who are disabled and wheelchair bound have to undergo a transfer process to board and deplane a commercial aircraft. This transfer process is typically done manually, with agents physically lifting the passenger who is...

Vegetation and soil response to tree removal methods in invasive western juniper woodlands

Creator:: O'Connor, Casey A.
Abstract:: On piñon-juniper encroached sites that lack the understory fuels to carry a prescribed fire, treatment options are limited to mechanical methods. Cutting with chainsaws and leaving the trees on site has been the primary treatment method for such sites, however this method creates a potential fire hazard, particularly in the...

Distortion-induced fatigue cracking of girder-to-crossbeam connection

Creator:: Aljutaili, Dhari S.
Abstract:: Oregon Department of Transportation’s bridge no. 9743b is a multi-span, two-girder steel deck bridge connecting the busy interstates 5 and 205. Vertical cracks have been detected in the welded girder-to-crossbeam connections at the bents. Distortion-induced fatigue is suspected to be responsible for the cracking. Linear elastic beam analysis, 2-D and...

Public acceptance of disturbance-based forest management : a study of the attentive public in the Central Cascades Adaptive Management Area

Creator:: Mallon, Angela L.
Abstract:: Growing emphasis on ecosystem and landscape-level forest management across North America has spurred an examination of alternative management strategies which focus on emulating dynamic natural disturbance processes, particularly those associated with forest fire regimes. This topic is the cornerstone of research in the Blue River Landscape Study (BRLS) taking place...

Inter-relationships of vegetation, hydrology and micro-climate in a young, Douglas-fir forest

Creator:: Barnard, Holly Rene
Abstract:: The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...

Stripe rust resistance pyramids in barley

Creator:: Castro Tabo, Ariel Julio
Abstract:: Genetic resistance is the most appropriate way to control diseases in crop plants. Resistance can be described as qualitative (involving a gene-for-gene system) or quantitative (with continuous distribution of disease levels). The relationships between different types of resistance remain obscure, as does the genetics of quantitative traits. The use of...
