Abstract:: Hypoxia is a naturally occurring phenomenon that happens seasonally off the Oregon coast. As a consequence, there has been a great deal of research focused around analyzing the strength and duration of the hypoxic event during the summer season. This paper, however, takes an innovative approach by looking at the...

Abstract:: Abstract Flame-retardants (FRs) generally enter the environment by dissociating from the products they were originally manufactured into. The predominant class of FR used in consumer products before their eventual phase-out in the mid-2000s were the polybrominated diphenyl ethers (PBDEs). Previous studies have illustrated a correlation between socio-economic status, notably gross...

Abstract:: Firemaster 550 (FM550) is an additive flame retardant mixture used within polyurethane foam and is increasingly found in house dust and the environment due to leaching. In this study, we sought to investigate mono-substituted isopropylated triaryl phosphate (mITP), a major component of FM550, which has been shown to cause cardiotoxicity...

Abstract:: Oregon White Oaks (Quercus garryana) were once abundant in the Willamette Valley, Oregon, but have drastically decreased because of fire suppression, agriculture, and human development. Oaks are an important ecosystem because they provide a diverse habitat for bird species that are insectivorous and/or cavity nesters. We studied the oak restoration...

Abstract:: Pactamycin, a complex aminocyclitol compound produced by Streptomyces pactum, has significant antibiotic, antitumor, and antiplasmodial activity. However, this natural product has not been developed for clinical use due to its high cytotoxicity. Modulation of its biological properties by chemical synthesis has been difficult due to its complex chemical structure. Therefore,...

Abstract:: Hart Mountain National Antelope Refuge (HMNAR) established in 1936, is 101,000 ha in area. The refuge was grazed by domestic livestock from the 1870s until their exclusion in 1990. Just prior to removal of livestock, photopoints were taken at various riparian and wetland locations throughout the refuge to document riparian...

Creator:: Neumann, Kyle
Abstract:: Extraction of natural gas from shale formations using the process of hydraulic fracturing (fracking) requires the use of thousands of cubic meters of fluid. Hydraulic fracturing fluids are pumped under pressure into shale formations, fracturing the shale and releasing pockets of trapped gases. When the pressure in a natural gas...
