Storm-Dominated Lower Cambrian Depositional Environments In The Ravenswood Area, Lander County, Nevada, Readin Isaac Wilson
Storm-Dominated Lower Cambrian Depositional Environments In The Ravenswood Area, Lander County, Nevada, Readin Isaac Wilson
UNLV Retrospective Theses & Dissertations
A Lower Cambrian sedimentary sequence 40 meters thick is exposed in the Ravenswood area, Lander County, Nevada. This sequence is divided into 7 lithofacies which are interpreted to represent marine, littoral to sublittoral environments including offshore bars, sheet deposits (proximal, intermediate, distal), patch reefs, and storm-surge ebb channels; The lithology, paleontology, and sedimentary structures reflect deposition in a wave-dominated or storm-dominated system. Paleocurrent indicators suggest that strong westerly (present orientation of continent) winds created landward-directed currents transporting carbonate debris from the shelf to nearshore environments. Subsequently, storm-surge-ebb flows transported nearshore sediments seaward; The lithofacies presented herein indicate that sediments were …
Is Family Environment A Mediator Of Bulimia And Child Sexual Abuse?, Teresa Lynn Hastings
Is Family Environment A Mediator Of Bulimia And Child Sexual Abuse?, Teresa Lynn Hastings
UNLV Retrospective Theses & Dissertations
Reports concerning the high rate of child sexual abuse in bulimic populations have not generally been supported by empirical investigations. The current study addressed methodological problems that may have accounted for insignificant results, and investigated family environment as a possible mediator of the relationship. Results indicate a significant correlation between bulimia and child sexual abuse within a sample of college women (n = 786). Furthermore, both women with bulimia and victims of child sexual abuse reported families that were low in cohesion and independence, and higher in conflict and control. Family environment did not significantly mediate or moderate the relationship …
Model Linkages Between A Hazardous Waste Transportation Impact/Risk Assessment Model And A Transportation Planning Model In A Geographic Information System Environment, Justin Paul Rasas
Model Linkages Between A Hazardous Waste Transportation Impact/Risk Assessment Model And A Transportation Planning Model In A Geographic Information System Environment, Justin Paul Rasas
UNLV Retrospective Theses & Dissertations
Several computer models are currently available that can address portions of nuclear waste transportation analysis. However, no single computer model is currently available to permit an integrated analysis that provides effective graphical display of results and product generation. One model available for analysis related to the transport of hazardous material is Radtran. Radtran requires difficult to obtain data and its outputs are presented in a tabular format. A travel demand model, such as Tranplan, can provide some of the data required for Radtran analysis, but the format of its output is not in a form Radtran can readily use. For …
