The thermal decomposition of tungsten hexacarbonyl was
investigated in an apparatus which allowed a solid sample of the material
to be sealed into a preheated batch reactor. Because the reaction occurs
with an increase in the number of moles of gas, it was possible to monitor
the progress of the...
The Purpose of the Study The purpose of this study was to identify the tasks performed by low-ability office employees as viewed by office supervisory personnel, and, also, to analyze these tasks. The study was conducted in Alberta, Canada. To analyze tasks performed by low-ability office employees, it was necessary...
Decentralizing resource control for community-based natural resource management (CBNRM) is a widely promoted scheme for natural resource governance worldwide. Researchers and policymakers have suggested that this approach has the potential to achieve positive social outcomes and succeed where centralized resource conservation has been inadequate. In reality, the powers transferred are...
The combined activities of diverse heterotrophic marine microorganisms significantly shape global biogeochemical cycles, but models of these activities are currently limited to aggregate microbial community processes, and it remains unclear how community structure and the functional roles of specific microbial taxa should be integrated into these models. Therefore, understanding the...
Excavations conducted at Indian Sands (35-CU-67C), located along Oregon's southern coast, during 2002 and 2003 identified two discreet, artifact-bearing stratigraphic units. The uppermost unit is a deflated surface containing burnt shell and lithic artifacts associated with early Holocene ¹⁴C dates, while the underlying unit contained only lithic tools and debitage,...
The entire human population is chronically exposed to various
contaminants, including lead and chlorinated hydrocarbon pesticides.
Studies were undertaken to assess the effects of chronic exposure to
lead on the toxicities of two such pesticides, lindane and dieldrin.
Mice were given lead as the acetate in drinking water, at levels...
This thesis examines the influence of Christian missions on Yung Wing (1828-1912) during the nineteenth century, when China was beginning to encounter the West. Yung was the first Chinese graduate student to enter an American institution of higher education (Yale College, 1854). As a Westernized Christian intellectual, he strove to...
Everyone involved with the mining and petroleum industries, either directly or indirectly, is aware of the mounting concern by the general public with the possibly deleterious effects of mineral exploration and development on the environment. Oftentimes the outcry about "desecration of the land" is not based on actual knowledge of...
Manned missions beyond low-Earth orbit present tremendous, multifaceted radiological challenges. The deep space radiation environment contains high-energy protons and heavy ions, which are not sufficiently shielded by the aluminum alloys that have historically been used in spacecraft. To address these shielding concerns, polymer-based nanocomposites have been proposed. Radiation transport simulations...
