Bitcoin is a digital cryptocurrency, meaning that it is a currency that is not backed by any government, uses cryptography for security and is difficult to counterfeit. Bitcoin’s popularity stems from the fact that it has little regulation and affords some degree of anonymity in transactions. Bitcoin currently has little...
A study, consisting of two sequential greenhouse experiments, was
designed to determine the effects of soil liming upon the fungal
partner in a mycorrhizal association. A Willamette Valley foothill
soil, of the Jory series, was limed in increments to achieve a range
of acidity and alkalinity. The P-deficiency and P-fixing...
The purpose of this study was to clarify the relationship between religiosity and sexual behavior of college students by using a measure of religious orientation to define religiosity. Religious orientation refers to individuals' motivations for religious involvement and personal faith. Religious orientations are characterized as being extrinsic, intrinsic, indiscriminately proreligious...
This thesis explores the factors limiting the alkene substrate range of the vinyl chloride (VC)-utilizing bacteria, and describes a method for measuring VC transformation in situ. Vinyl fluoride (VF) was evaluated as a surrogate for monitoring aerobic VC-transformation utilizing three isolates, Mycobacterium EE13a, Mycobacterium JS60 and Nocardioides JS614. JS614 grew...
Deforestation, intensive agriculture and chemical use all can cause long-lastingn negative impacts on soil health. With all the vital functions that soils perform and the potential for further soil degradation, it is important that standards of soil quality or soil health be implemented. Soil aggregation is considered to be a...
The Northwest Archivists (NWA), a regional archival association in the Pacific Northwest, established a formal mentoring program in 2007. A pilot phase of the program ran for 2 years and included both formative and summative assessments from participants. This case study documents NWA’s experiences designing and managing a mentoring program...
Climate changes in the Pacific Northwest, USA, may cause both retreat of alpine glaciers and increases in the frequency and magnitude of storms delivering rainfall at high elevations absent significant snowpack, and both of these changes may affect the frequency and severity of destructive debris flows initiating on the region's...
Cattle grazing and invasion by non-native plant species are globally-ubiquitous changes occurring to plant communities that are likely to reverberate through whole food webs. We used a manipulative field experiment to quantify how arthropod community structure differed in native and non-native California grassland communities in the presence and absence of...
