Development of acoustic emissions testing procedures applicable to conventionally reinforced concrete deck girder bridges subjected to diagonal tension cracking

Creator:: Lovejoy, Steven C.
Abstract:: A need exists to develop a non-destructive testing technique that can identify the formation and propagation of diagonal tension cracks in conventionally steel reinforced concrete deck girder (RCDG) highway bridges in the State of Oregon. Such a technique could be included into a structural health monitoring (SHM) system installed on...

Assessing the impact of temperature on grape phenolic metabolism

Creator:: Cohen, Seth D.
Abstract:: Many climatic factors influence grape berry composition including nutrient status, water availability, biotic stress, sun exposure and temperature. Previous research examined the effects of many factors listed above and much progress has been made. It is often difficult, however, to separate effects that typically confound each other, such as sun...

Influence of vine vigor and shading in Pinot noir (Vitis vinifera L.) on the concentration and composition of phenolic compounds in grapes and wine

Creator:: Cortell, Jessica M.
Abstract:: In 2003 and 2004 vigor zones were delineated in two commercial vineyard sites based on vine growth variation to assess fruit and wine phenolic chemistry. In 2004, the effects of shading on the accumulation of phenolic compounds were also investigated. Model extractions were done from the shading experiment and the...

Automating aquatic insect identification through pattern recognition

Creator:: Thomas, Joshua K.
Abstract:: Aquatic insect population counts can be a good indicator of the health, or water quality, of rivers and streams. Stoneflies (Plecoptera) are particularly susceptible to pollution in streams. However, today’s current method for obtaining these population counts requires biologists to examine individual specimens under a microscope for identification to 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...

Effect of berry integrity on proanthocyanidin extraction during wine production

Creator:: Cerpa-Calderon, Fiorella Karen
Abstract:: Proanthocyanidins are a grape-derived phenolic class of compound that provide wine with bitterness and astringency. Because of this, proanthocyanidins are considered to be essential components of wine quality. Proanthocyanidins are localized in the seed, skin and stem tissue of the grape berry and the composition of proanthocyanidins will vary depending...

Seasonal movement patterns and habitat use of westslope cutthroat trout in two headwater tributary streams of the John Day River

Creator:: Starcevich, Steven J.
Abstract:: Radiotelemetry was used to study the seasonal movements and habitat use of adult westslope cutthroat trout Oncorhynchus clarki lewisi in Roberts Creek and Rail Creek, headwater tributaries of the John Day River, Oregon, from September 2000 to December 2001. The objectives were to (1) describe adult cutthroat trout life history...

Remote sensing of forest aboveground biomass using the Geoscience Laser Altimeter System

Creator:: Pflugmacher, Dirk
Abstract:: Accurate estimates of forest aboveground biomass are needed to reduce uncertainties in the terrestrial carbon flux. The Geoscience Laser Altimeter System (GLAS) onboard the Ice, Cloud and land Elevation Satellite is now the first spaceborne lidar sensor that will provide global estimates of vegetation height. This study investigated the utility...
