Characterization of Heterostructured Nanocrystalline Metals Processed by High-Pressure Torsion

Creator:: Han, Jae-Kyung
Abstract:: High-pressure torsion (HPT) is an effective severe plastic deformation (SPD) technique to produce bulk nanostructured materials (BNMs). These BNMs often show a combination of exceptional mechanical and physical properties. Processing of single metals and alloys by HPT has been understood that the homogenous microstructures can be achieved throughout the disk...

Time used for household work : comparisons for farm, rural nonfarm, and urban women

Creator:: Meiners, Jane Ella
Abstract:: This study examined time spent in various activities by farm women. Emphasis was placed on household work time and how time is apportioned among various household work activities. Time use of farm women was compared to rural nonfarm women and urban women. Data were from An Interstate Comparison of Urban/Rural...

Education of American research astronomers, 1876-1941

Creator:: Hall, Robert Dale, 1947-
Abstract:: The education (particularly graduate education) of Americans who were active in astronomical research between 1876 and 1941 is assessed for its effectiveness in preparing the astronomers for careers in research. This period contains three dynamic changes: the growth of American astronomy in becoming the world's leading community of astronomers, the...

Phylogenetics, Biogeography, Morphological Variation, and Taxonomic Revision of Sandelia capensis (Cuvier 1829) (Anabantiformes: Anabantidae), a Freshwater Fish from the Coastal Streams of the Cape Region, South Africa

Creator:: Bronaugh, Whitcomb Meade
Abstract:: Accumulating human impacts on freshwater ecosystems have created a biodiversity crisis for freshwater fishes while conservation efficacy remains hampered by the Linnaean shortfall, the ignorance of many species that have yet to be discovered and described. The past discovery of most freshwater fish species was simply a matter of collecting...

Stable Isotope Constraints on Carbon Dioxide and Nitrous Oxide Variations at the Onset of the Last Glacial Period: New Ice Cores from Taylor Glacier, Antarctica

Creator:: Menking, James A.
Abstract:: New ice cores retrieved from the Taylor Glacier (Antarctica) blue ice area contain ice and air spanning the Marine Isotope Stage (MIS) 5/4 transition, a period of global cooling and ice sheet expansion. Chronologies were determined for the ice and air bubbles in the new ice cores by visually matching...

Management strategies and time use in food preparation in two-parent, two-child Utah families

Creator:: Steggell, Carmen Dobson
Abstract:: The management of the home has been a central component of Home Economics since the early 1900s. It is, however, an enigmatic behavior that has not yielded easily to research. Recognizing that meal provision and food consumption by families incorporate management processes and occur on a regular and frequent basis,...

Nanotoxicology to Nanotherapeutics : Prioritizing Hazard and Anticancer Efficacy of Nanomaterials using the Embryonic Zebrafish Model

Creator:: Wehmas, Leah C.
Abstract:: The numerous different types of nanomaterials and paucity of reliable in vivo information on toxicity has resulted in enduring uncertainties associated with health and safety risks, thereby slowing progress in nanotherapeutic assessment and development. This dissertation explores how the embryonic zebrafish model can be applied to prioritize commonly used nanomaterial...

An analysis of ecological indices and leisure participation with selected dimensions of self-concept among the elderly

Creator:: Guadagnolo, Frank Bernard, 1940-
Abstract:: The primary focus of this investigation was to assess whether or not selected ecological indices and leisure preferences demonstrated statistically significant relationships with the aged's self-concept. Gerontology, a relatively embryonic discipline, has only recently begun to examine the impact of demographic, physical and socio-psychological stresses upon the geron's self-concept. Even...
