Optimization Of A Retrofit Urea-Scr System, Clinton R. Bedick
Optimization Of A Retrofit Urea-Scr System, Clinton R. Bedick
Graduate Theses, Dissertations, and Problem Reports (ETD)
Oxides of nitrogen (NOx) emissions from legacy diesel engines are often many times over currently mandated standards, contributing significantly to degradation of air quality and negative environmental impact. A retrofit urea-SCR (selective catalytic reduction) aftertreatment system offers a viable solution for reducing NOx emissions from older diesel engines. A stand-alone retrofit urea-SCR aftertreatment system was previously developed by West Virignia University (WVU) engineers, implementing a pre-SCR NOx sensor, open-loop feed-forward control, and stoichiometric NOx reduction logic. During experimental testing at WVU, the urea-SCR system demonstrated NOx reductions of 2% to 53%, depending on the test cycle. In order to optimize …
Weak Floor Stability In The Illinois Basin Underground Coal Mines, Murali M. Gadde
Weak Floor Stability In The Illinois Basin Underground Coal Mines, Murali M. Gadde
Graduate Theses, Dissertations, and Problem Reports (ETD)
The research described in this dissertation is a direct consequence of the author's quest to find solutions to several problems he faced while designing optimum pillar layouts for some Illinois Basin coal mines over weak immediate floor strata. When using the existing methods of floor stability analysis, conclusions were sometimes drawn that were either not supported by real-world mining experience or in some cases even physically impossible results were obtained. Therefore, it was necessary to delve deeper into the existing methods and understand their limitations to arrive at alternatives that were consistent with practical observations. In improving upon the existing …

Evaluation Of Industrial Promoted Agroforestry In Andhra Pradesh And Madhya Pradesh, India, Brian D. Mcdonald
Evaluation Of Industrial Promoted Agroforestry In Andhra Pradesh And Madhya Pradesh, India, Brian D. Mcdonald
Graduate Theses, Dissertations, and Problem Reports (ETD)
In many parts of the world, pulp and paper companies are becoming heavily dependent on private agroforestry schemes. With growing demand for wood fiber and limited commercial land to grow it on, the forest industry is continually turning to private farmers and individuals to contract timber. In order to alleviate this problem, many companies have turned to out-grower schemes to supply wood to the mills. Local farmers now have the opportunity to benefit from company extension and supplies, and in return, the company can guarantee its supply of raw materials.;A recent trend in agriculture is adding trees to farmers? traditional …
Interleukin (Il)-1 Regulates Ozone-Induced Nerve Growth Factor (Ngf) And Substance P (Sp) Release In Bronchoalveolar Lavage Fluid (Balf) In Mice, Joshua S. Barker
Interleukin (Il)-1 Regulates Ozone-Induced Nerve Growth Factor (Ngf) And Substance P (Sp) Release In Bronchoalveolar Lavage Fluid (Balf) In Mice, Joshua S. Barker
Graduate Theses, Dissertations, and Problem Reports (ETD)
Previous studies show that both IL-1 and NGF increase synthesis of SP in airway neurons after either direct application or ozone exposure. We hypothesize that NGF mediates ozone-induced IL-1 effects on SP, similar to the pathway described for sympathetic neurons in culture. The current study specifically focuses on the effect of ozone on IL-1, NGF, and SP levels in mice BALF and if these mediators can be linked in an inflammatory-neuronal cascade in vivo. The experiments demonstrate in vivo ozone exposure induces an increase of all three proteins in mouse BALF and that both ozone-induced increases in NGF and SP …

A Process Examination Of The Framing Effect In Younger And Older Adult Medical Decision Making, Erin L. Woodhead
A Process Examination Of The Framing Effect In Younger And Older Adult Medical Decision Making, Erin L. Woodhead
Graduate Theses, Dissertations, and Problem Reports (ETD)
Older and younger adults are susceptible to a decisional bias when faced with medical decisions, which results in different treatment decisions when presented with survival or mortality data. Although this bias, termed the framing effect, has been demonstrated in multiple studies, no published studies have attempted to determine the decisional process older and younger adults engage in when presented with different information frames. The current study used a think-aloud procedure to examine decisional process differences in younger and older adults who did and did not demonstrate a framing effect. All participants were presented with two data formats (interval and cumulative …

The Evaluation Of A Nutrition Education And Fitness Program With A Contest Component Among College Students Using The Re-Aim Framework, Michelle L. Bartlett
The Evaluation Of A Nutrition Education And Fitness Program With A Contest Component Among College Students Using The Re-Aim Framework, Michelle L. Bartlett
Graduate Theses, Dissertations, and Problem Reports (ETD)
Only recently have practitioners and researchers targeted the population of college students in studying interventions aimed at increasing health behaviors. There is evidence that a proportion of college students are making attempts on their own to remedy weight gain and poor physical fitness with little or no guidance, which is reflected in consistently rising obesity rates in this population. Thus, the need for organized and effective interventions is illustrated. The impact of an intervention can be determined through evaluation research. Although the RE-AIM model has not yet been used to evaluate single-site, university-sponsored, college-student weight-loss/fitness programs, it provided a useful …

The West Virginia Division of Natural Resources (WVDNR) continued to monitor the black bear population and increased monitoring efforts and sample sizes in the 1990's as the black bear population increased in size and expanded its range. As part of the WVBBRP, we investigated black bear population ecology. Our objectives were to estimate reproductive rates, estimate survival and cause-specific mortality rates, examine effects of special hunting seasons …
Post-Transcriptional Regulation Of Rpos And Hema In Salmonella, Amy Madeline Jones
Post-Transcriptional Regulation Of Rpos And Hema In Salmonella, Amy Madeline Jones
Graduate Theses, Dissertations, and Problem Reports (ETD)
The first part of this thesis is dedicated to translational regulation of rpoS mRNA by the small noncoding RNAs (sRNAs), DsrA and RprA, in two closely related enteric bacteria, Escherichia coli, and Salmonella enterica serovar Typhimurium. The rpoS gene encodes a second vegetative sigma factor for RNA polymerase, which directs the cell's transcriptional response to general stress and entry into stationary phase. The rpoS gene is highly conserved among the gamma-branch of proteobacteria, and sRNAs are highly conserved in related species. In fact, sequence conservation is thought to have predictive value in sRNA discovery and functional conservation is largely assumed. …
Mechanism By Which Dietary Polyunsaturated Fat Regulates Lipogenic Gene Expression, Alison Bloom Kohan
Mechanism By Which Dietary Polyunsaturated Fat Regulates Lipogenic Gene Expression, Alison Bloom Kohan
Graduate Theses, Dissertations, and Problem Reports (ETD)
Primary hepatocytes treated with non-esterified polyunsaturated fatty acids have been used as a model for describing the inhibitory effects of dietary polyunsaturated fats on lipogenic gene expression. This model resembles starvation or uncontrolled diabetes but not dietary fat ingestion, which is delivered to liver via chylomicron remnants. Chylomicron remnants enriched with polyunsaturated fatty acids stimulate a unique pattern of intracellular signaling. These remnants enhance p38 mitogen activated protein kinase (MAPK) activity but do not inhibit insulin signaling or induce extracellular-signal related kinase (ERK) or AMP-activated protein kinase (AMPK) activation as do non-esterified polyunsaturated fatty acids. Polyunsaturated fatty acids-enriched remnants and …

Unfortunately, the exact mechanics of coal bumps is still not fully understood. Following this period, research into coal bumps in the United States has been limited.;The Energy Release Rate (ERR) calculation quantifies the dissipation ("release") of the …
Improvement Of The Mine Fire Simulation Program Mfire, Lihong Zhou
Improvement Of The Mine Fire Simulation Program Mfire, Lihong Zhou
Graduate Theses, Dissertations, and Problem Reports (ETD)
Fire represents one of the most severe hazards to underground mines. A good understanding of the interaction between a mine fire and the mine ventilation network would be very crucial for fire emergency planning and hazard control. MFIRE, an underground mine fire simulation program developed in 1980's, is a tool that can be used to simulate the impacts of a mine fire event to a mine ventilation network. However, the lack of the abilities to simulate some of the important mine fire phenomena realistically hindered its wide applications. This research has been carried out to improve the MFIRE program. The …

Design Of Reinforced Concrete Seals For Underground Coal Mines, Rajagopala Reddy Kallu
Graduate Theses, Dissertations, and Problem Reports (ETD)
The conventional 'full-scale' explosion test for seal evaluation is expensive and time consuming. Therefore, alternative methodologies must be developed for the design of mine seals to meet the new MSHA design standards. This dissertation employed advanced explicit finite element code, ABAQUS, to develop reinforced concrete (RC) seal models for addressing various design parameters related to the RC seal design.;Firstly, using back analysis of structural data available from NIOSH full-scale explosion tests on RC seals, a suitable RC seal model was developed with a proper concrete constitutive material. Secondly, the optimum rebar parameters such as rebar diameter, and vertical and horizontal …

An Interpretive Inquiry Of The Case Law Of Teacher Evaluation In The Southern Regional Education Board States: Forecasting Pressing Problems, Kathy S. Kidder-Wilkerson
Graduate Theses, Dissertations, and Problem Reports (ETD)
The purpose of this study was to analyze case law related to teacher evaluation between 1980 and 2008 in the SREB states to determine the problems associated with teacher evaluation and if these problems were documented in the literature. Content analysis of teacher dismissal cases revealed many types of teacher evaluation problems. The two most frequent were in the categories of process and data. Problems revealed in case law provide evidence that teacher evaluation is a problematic practice and may be prevented from achieving its accountability goal. Since not all problems that were identified in case law were revealed in …

Investigation Into Pedestrian Exposure To Near-Tailpipe Exhaust Emissions, Neil A. Buzzard
Investigation Into Pedestrian Exposure To Near-Tailpipe Exhaust Emissions, Neil A. Buzzard
Graduate Theses, Dissertations, and Problem Reports (ETD)
Inhalation of particulate matter is known to cause negative human health effects. Consequently, regulatory agencies have set regulations and standards that limit the maximum concentrations to which persons may be exposed and the maximum concentrations allowed in the ambient air. However, these standards consider steady exposure over large spatial and time scales. Because many vehicles' exhaust systems direct exhaust towards sidewalks, pedestrians in close proximity to a roadway may experience events where for brief periods of time particulate matter concentrations are high enough to cause acute health effects. In order to quantify these exposure events, instruments which measure specific exhaust …
