Judicial deference and its potential effect on agency science and natural resource management

Creator:: Grisa, Amanda Marie Schenk
Abstract:: The USDA Forest Services' actions have come under greater scrutiny by a public that has become increasingly concerned with the legality of their actions. Often, challenges involve the quality of science used in the decision-making. Congress has mandated that the agency use the "best available science" in its decision making...

Effects of Preinoculation with VAM fungi isolated from different sites on plant tolerance to salinity in soils amended with sodium chloride

Creator:: Cantrell, Isabella Cardona
Abstract:: The hypothesis that inoculation of transplants with vesicular-arbuscular mycorrhizal (VAM) fungi before planting into saline soils would alleviate salt effects on growth and productivity was tested on lettuce (Lactuca sativa L.) and onion (Allium cepa L.). A secondary hypothesis was that the fungi isolated from a saline soil would be...

Microbial alteration of the seafloor

Creator:: Josef, Jennifer A.
Abstract:: In the early 1980's the first evidence of biological alteration of basalt glass (sideromelane) was published. Since that time additional evidence, including DNA staining, isotopic abundance and chemical mapping, has come to light suggesting that this unique alteration of glass can be attributed to microbial activity. Microbial alteration textures have...

High cycle fatigue modeling and analysis for deck floor truss connection details

Creator:: DePiero, Anthony H.
Abstract:: The Oregon Department of Transportation is responsible for many steel deck truss bridges containing connection details that are fatigue prone. A typical bridge, the Winchester Bridge in Roseburg, Oregon, was analyzed to assess the loading conditions, stress levels, and fatigue life of the connection details. The analysis included linear-elastic beam...

Habitat use, movement, and life history variation of coastal cutthroat trout, Oncorhynchus clarkii clarkii, in the Salmon River estuary, Oregon

Creator:: Krentz, Lisa K.
Abstract:: Anadromous coastal cutthroat trout Oncorhynchus clarkii clarkii may be highly dependent on estuaries, passing through them multiple times during their lifetime. However, few studies have investigated estuarine use by coastal cutthroat trout and it is often thought that estuaries serve primarily as migration corridors rather than rearing areas. We used...

Evidence of buried particulate organic carbon as foundation for heterotrophic carbon metabolism in the hyporheic zone of a montane headwater stream in the H. J. Andrews Experimental Forest, Oregon, USA

Creator:: Serchan, Satish P.
Abstract:: Streams and rivers play a critical role in global carbon (C) cycling by processing, storing, and transporting C. Headwater streams which make up more than 95% of the length of streams and rivers worldwide have disproportionate influence on fluvial C dynamics. The hyporheic zone (HZ) of headwater streams is a...

A quantitative structure activity relationships study of antiinfectives based on the nalidixic acid structure

Creator:: Yu, Yupei
Abstract:: Nalidixic acid and its derivatives act through inhibition of bacterial DNA gyrase activity. Recently there have been a series of papers reporting the antibacterial activity against three different types of bacteria (S. aureus, E. coli and P. aeruginosa) by a series of 1,4-dihydro-4-oxoquinoline (or 1,8-naphthyridine) 3-carboxylic acids. Consistent biological data...

Trends in streamflow above and below dams across the Columbia River basin from 1950 to 2012 : assessing sub-basin sensitivity

Creator:: Hammond, John C.
Abstract:: Climate change, combined with population growth, is expected to exacerbate water scarcity globally. In the Columbia River basin (CRB), streamflow is managed for multiple objectives with a network of dams and reservoirs distributed throughout the basin that may mitigate climate change effects on water scarcity. This study quantified trends in...

Single fault detection in combinational logic circuits

Creator:: Medhekar, Ranjana A.
Abstract:: The material in this paper is divided into the following four chapters for convenience. Chapter 1 explains, how the idea of fault testing changed from testing the machine instructions to testing the hardware in logic circuits. Chapters 2, 3 and 4 present the different approaches considered, namely: 1. Path sensitizing...
