Petrologic Study Of The Murrysville Sandstone In Southwestern Pennsylvania, Melissa L. Sager May 2007

Petrologic Study Of The Murrysville Sandstone In Southwestern Pennsylvania, Melissa L. Sager

Graduate Theses, Dissertations, and Problem Reports (ETD)

Pennsylvania's Murrysville sandstone has been a proven gas producer since 1859 and a gas storage field since 1951. Using 49 side-wall cores from a gas well drilled in Westmoreland County, depositional environment and diagenesis are examined. In thin section, 5 microfacies are recognized. The lower two-thirds of the Murrysville is equivalent to the Cussewago of northwestern Pennsylvania and is interpreted as fluvial deltaic. The upper third is equivalent to the Berea of Ohio and is interpreted as being a marine transitional stream deposit.;Compaction was not extensive due to low amounts of ductile grains, rigid grain stability and matrix occupying space …

Indian Warfare, Household Competency, And The Settlement Of The Western Virginia Frontier, 1749 To 1794, John M. Boback May 2007

Indian Warfare, Household Competency, And The Settlement Of The Western Virginia Frontier, 1749 To 1794, John M. Boback

Graduate Theses, Dissertations, and Problem Reports (ETD)

The thesis of this dissertation is that Indian-related violence and warfare had a profound influence on the duration and nature of the frontier experience of those men and women who settled in the western Virginia backcountry between 1749 and 1794. Recurrent attacks by Shawnees, Delawares, Mingos, and Indians from the Great Lakes region caused such widespread death, destruction, and depopulation that it effectively prolonged the period of austere and difficult living conditions for over forty years. This conclusion contradicts the assertions of some recent scholars who have argued that crude living conditions lasted for only a year or two on …

Social Rank And Social Anxiety, Jennifer A. Chrystan May 2007

Social Rank And Social Anxiety, Jennifer A. Chrystan

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of the current study was to investigate a primary assumption of social rank theory. More specifically, the purpose was to determine whether the perception of social inferiority leads to increased anxiety during social interaction, with a heightened effect occurring among those who are more socially anxious. Although multiple studies have demonstrated shared covariates between social anxiety and perceptions of inferiority, virtually no research has been dedicated to scrutinizing the causal relationship proposed by social rank theory. One hundred undergraduate students at West Virginia University participated in this study. Participants engaged in three social interaction tasks with a same-gender …

Epithelial Mechanisms In Airway Responses Induced By Hyperosmolarity, Yi Jing May 2007

Epithelial Mechanisms In Airway Responses Induced By Hyperosmolarity, Yi Jing

Graduate Theses, Dissertations, and Problem Reports (ETD)

There is airway dilation in normal people but obstruction in asthmatic patients during exercise; this has been thought to be initiated by hyperventilation causing evaporative water loss and hyperosmolarity of the airway surface liquid (ASL). In animal experiments the epithelium can detect osmolarity increases in the ASL and mediate relaxation of airway smooth muscle by releasing epithelium-derived relaxing factor (EpDRF), while in asthmatic patients this local regulatory function could be altered because of damage to epithelium. Challenged by hyperosmolarity, epithelial cells undergo shrinkage, volume-related ion transport, and release regulatory mediators, such as EpDRF. The changes in epithelial ion transport and …

Using Blended Instruction To Teach Academic Vocabulary Collocations: A Case Study, M. Teresa Das Neves Seesink May 2007

Using Blended Instruction To Teach Academic Vocabulary Collocations: A Case Study, M. Teresa Das Neves Seesink

Graduate Theses, Dissertations, and Problem Reports (ETD)

Learning second language vocabulary has always been a challenge for second language (L2) learners. Transferring new vocabulary to an active stage has been an even greater challenge.;In the 1990s, Lewis (2002a) proposed the Lexical Approach as a means to help L2 learners with vocabulary acquisition. This approach encouraged the teaching of vocabulary in chunks, or in other words, putting emphasis on collocations. Focus on vocabulary collocations was suggested by several researchers (Brown, 1974; Hinkel, 2004; Lewis, 2001). They supported the teaching of collocations via in-class exercises. Cobb (1999) and Kaur and Hegelheimer (2005) showed that the use of a concordancer---an …

Genetic And Evolutionary Consequences Of Harvest In American Ginseng, Panax Quinquefolius L. (Araliaceae), Emily H. Mooney May 2007

Genetic And Evolutionary Consequences Of Harvest In American Ginseng, Panax Quinquefolius L. (Araliaceae), Emily H. Mooney

Graduate Theses, Dissertations, and Problem Reports (ETD)

American ginseng (Panax quinquefolius L.) is a wild-harvested perennial plant of the eastern deciduous forest. Harvest supplies world markets with roots used in Asian medicine, but this practice is fatal to plants. The objective of this research was to investigate the genetic and evolutionary consequences of harvest. As seen in animal species, harvest may alter size selection by preferentially removing large individuals. Chapter 2 describes my study of harvest's effects on size selection. From the simulated harvests, I observed that large-sized plants lose their fitness advantages in harvested populations. Harvest pressure could ultimately lead to population divergence if selected traits …

Molecular Mechanisms Of Chromium(Vi)-Induced Apoptosis And Malignant Transformation, Neelam Azad May 2007

Molecular Mechanisms Of Chromium(Vi)-Induced Apoptosis And Malignant Transformation, Neelam Azad

Graduate Theses, Dissertations, and Problem Reports (ETD)

Hexavalent chromium [Cr(VI)] compounds are redox cycling environmental carcinogens that induce apoptosis as the primary mode of cell death. Apoptosis is abnormally regulated in various disorders including cancer. Therefore, to understand the etiologies of these diseases, it is important to delineate the biochemical and molecular pathways involved in the regulation of apoptosis. The main objective of this study was to characterize the molecular mechanisms involved in Cr(VI)-induced apoptosis and malignant transformation. We found that both death receptor and mitochondrial pathways of apoptosis are involved in Cr(VI)-induced apoptosis, with the latter being more dominant. Consequently, overexpression of the mitochondrial anti-apoptotic protein …

Development Of Water Production Type Curves For Horizontal Wells In Coalbed Methane Reservoirs, Praveen Kumar Burka Narayana May 2007

Development Of Water Production Type Curves For Horizontal Wells In Coalbed Methane Reservoirs, Praveen Kumar Burka Narayana

Graduate Theses, Dissertations, and Problem Reports (ETD)

Coalbed methane is an unconventional gas resource that consists of methane production from the coal seams. The key parameters for the evaluation of coalbed methane (CBM) prospects are the gas resources, reserves and deliverability. Coalbed methane reservoirs are dual-porosity media where the vast majority of the gas is stored in the low permeability coal matrix (primary porosity) by sorption. The flow to production wells, however, occurs through the coal's natural fracture system (secondary porosity), which stores relatively small amounts of gas, because coal matrix practically has no permeability.;For the gas to be released from the coal, its partial pressure must …
