Changes To In-Stream Turbidity Following Construction Of A Forest Road In A Forested Watershed In West Virginia, William Frank Sharp
Graduate Theses, Dissertations, and Problem Reports (ETD)
In 1999, a study was initiated in two forested headwater channels to compare and contrast changes to in-stream suspended sediment and turbidity following the construction of a forest haul road. Turbidity (NTU), suspended sediment concentrations (SSC) (mg L-1) and streamflow (L s -1), were measured throughout May 2005. Both catchments are ephemeral/intermittent tributaries of the Left Fork of Clover Run in the Cheat River watershed. To exclude inputs of hillside sediment both catchments were continuously lined with silt fence from constructed gauging/sampling stations to the upper most portions of their drainage network. In July 2002, construction of a 0.93 km …

An Evaluation Of The Strength Characteristics Of Horizontally Curved Steel I-Girder Bridges., Lauren E. Cullen
Graduate Theses, Dissertations, and Problem Reports (ETD)
Horizontally curved bridges occupy a growing number of the steel bridge population in the United States today because they are often one of the few options available for difficult roadway alignments. Horizontally curved bridges offer aesthetic and economic benefits over comparable straight-chorded bridges. However, there are additional design, analysis and construction issues to consider for horizontally curved bridges compared to the design of straight-chorded bridges. To ensure uniform standards and safety requirements, the FHWA created the Consortium of University Research Teams (CURT) in 1969 to conduct research on horizontally curved girders and develop guide specifications for design. In a cooperative …

The Effect Of Steam Conditioning Practices On Pellet Quality And Growing Broiler Nutritional Value., Sarah Elizabeth Cutlip
Graduate Theses, Dissertations, and Problem Reports (ETD)
Feed currently incurs 60-65% of the total cost of broiler production. Pellets are the primary feed form for commercially-reared broilers. Understanding how to optimize pellet quality through precision thermo-mechanical processing may impact broiler performance and nutrient availability, thus cost of production. Steam conditioning represents a manipulable thermo-mechanical processing variable. Corn-soybean meal based diets were conditioned with one of four steam pressure x temperature combinations: 138 kPa at 82.2ºC, 138 kPa at 93.3ºC, 552 kPa at 82.2ºC or 552 kPa at 93.3ºC. High steam pressure and temperature conditioning were shown to increase pellet quality. Three additional diets were prepared: unprocessed mash, …

Determination Of Diel Chemical Cycle Presence Within Abandoned Coal Mine Drainage Streams In Harrison County, West Virginia., Michael Jay Smilley
Graduate Theses, Dissertations, and Problem Reports (ETD)
Diel (24-hour) cycling of dissolved ions has been linked to various mechanisms such as fluctuations in temperature and photosynthetically-mediated pH. Yttrium and the rare earth elements (YREE) appear to fluctuate in response to temperature. After selecting a field site based on pH and temperature screening, five sampling events were undertaken: each involved hourly or bihourly sampling with concurrent stage, pH and temperature logging. For all events, YREE increased during the nighttime and decreased during the daytime. Dissolved Fe and Mn exhibited similar trends at one of the two sampled locations. Speciation models suggest that sulfate and carbonate-bound YREE species dominate …

Synthesis Of Polyol Natural Products: Applications To Rk-397 And Virginiamycin., Matthew S. Mortensen
Synthesis Of Polyol Natural Products: Applications To Rk-397 And Virginiamycin., Matthew S. Mortensen
Graduate Theses, Dissertations, and Problem Reports (ETD)
A 3-step method for the preparation of 2-methyl-l,3-syn diols was developed and demonstrated on several examples. A previous incarnation of this method was used in the formal synthesis of two polyoxygenated natural products. RK-397 is a 32-membered oxopolyene macrolide antibiotic which also exhibits anti-cancer activity. Virginiamycin M2 (also known as flavofungin I) is a member of the streptogramin antibiotic family which are active against vancomycin-resistant s. aureus. The methodology employed for setting many of the stereocenters in these two products is asymmetric catalysis. This allows for either enantiomer to be created and also is efficient by means of chirality multiplication.

An Analysis Of Transnational Corruption., Gregory P. Noone
An Analysis Of Transnational Corruption., Gregory P. Noone
Graduate Theses, Dissertations, and Problem Reports (ETD)
Transnational corruption is the type of corruption that crosses borders, involves corporate and state actors, and employs sophisticated and grand schemes to siphon the wealth of a country from its rightful owners: the people of the country. Quite simply, it is the grand theft of public funds for private gain. This is a significant problem because the amount of money stolen each year is staggering. Over one-quarter of Africa’s gross domestic product (GDP) is lost to corruption annually, and in Latin America about ten percent of their GDP vanishes due to corruption. Transparency International estimates that at least four hundred …
The Relation Between Hostility And Social Support: Investigating Potential Mediation Or Moderation By Trait Forgiveness, Attributional Style, And Trait Empathy., Benjamin Parker
Graduate Theses, Dissertations, and Problem Reports (ETD)
A substantial body of scientific literature has examined the relations among hostility, social support, and physical and psychological functioning. Typically, positive relations are observed between hostility and various problematic health concerns and negative relations are observed between social support and these same problematic health concerns. Hostility is commonly associated with decreased ratings of social support. The purpose of this study was to explore this relation between hostility and low social support, and determine whether three variables derived from the positive psychology literature (trait forgiveness, attributional style, and empathy) either moderate or mediate this relation. One hundred and fifty two female …

Issues For P-Type Doping Of Gallium Nitride With Beryllium And Magnesium Grown By Rf-Plasma Assisted Molecular Beam Epitaxy., Kyoungnae Lee
Graduate Theses, Dissertations, and Problem Reports (ETD)
P-type doping in GaN remains a critical issue for GaN-based electronic and optoelectronic devices. Accurate temperature measurement of GaN during molecular beam epitaxy growth is one of the decisive factors to obtain high p-type conductivity due to background carrier concentrations, leading to the compensation effect on p-type doping, and to issues related to dopant incorporation and solubility. Thermocouples or optical pyrometers have been used to determine the substrate temperature of GaN in conventional MBE systems. Both require secondary calibration, leading to inaccurate reading and poor reproducibility of substrate temperature. In-situ cathodoluminescence (CL) occurring during reflection high energy electron diffraction (RHEED) …

Perceptions Of The Environment For Physical Activity: Perspectives From Community Residents And Policy Officials., John R. Geer
Graduate Theses, Dissertations, and Problem Reports (ETD)
Adult residents (n = 184) of two counties in West Virginia completed a survey assessing perceptions of their physical and social environments, and self-reported physical activity (PA). Semi-structured interviews were conducted with nine of these participants who met CDC PA recommendations, and with 10 individuals involved in public policy regarding perceptions of their communities for PA and issues related to PA barriers. Active residents were more likely to use community facilities than inactive residents (p < .001). In addition, active residents reported significantly higher self-efficacy for meeting PA recommendations than inactive residents (p < .001). Overall, participants with high self-efficacy were eight times more likely to meet recommended levels of PA. Residents’ environmental barriers to PA included lack of accessibility to facilities, lack of community walkability, and safety and traffic issues. Personal barriers to PA were also commonly cited by residents, including being too busy/having competing demands and poor attitude/motivation. Residents cited the use of exercise partners or groups as being important for increasing physical activity. Policy officials cited similar environmental and personal barriers, but often placed responsibility for overcoming those barriers on the residents within their communities.

The Effect Of Different Sugar-Sweetened Beverage Intake By Immature Female Rats On Bone Mineralization And Strength., Embedzayi Tsanzi
Graduate Theses, Dissertations, and Problem Reports (ETD)
Consumption of sugar-sweetened beverages has increased among adolescents. This may have health implication because sugar consumption has been suggested to lead to decreased calcium (Ca) intake and increased urinary Ca output and these effects on Ca balance may have a negative impact on bone. Also, the type of sugar added to beverages has also changed from sucrose to high fructose corn syrup resulting in higher fructose consumption. Although sugarsweetened beverage intake by adolescent has increased and the type of sugar consumed has changed; the effects of sugar-sweetened beverage consumption during the bone growth stage on skeletal acquisition and adult bone …
