I also performed genetic analyses to assess overall population structure, mating system, parentage, kinship, and gender of individuals comprising these populations. A total of 415 grasshopper sparrows were captured and systematic searches of study plots produced 75 active nests. Nest survival for 2001--2002 breeding season (33%) is comparable to survival rates previously reported in the literature. Nest survival rates decreased with increased reclamation …
Empirical Development Of A Scale Of Patience, Kenneth C. Dudley
Empirical Development Of A Scale Of Patience, Kenneth C. Dudley
Graduate Theses, Dissertations, and Problem Reports
Patience is a construct not directly studied in the literature. Studies in the psychological literature have typically spoken of patience only as the converse of impatience. The assumption of these studies is that patience exists in the absence of impatience. However, other research proposes a multidimensional model of patience based on qualitative studies. It follows from the multidimensional model that patience exists on a continuum with the potential for different levels or amounts of patience across different situations. The purpose of this study was to develop an objective measure of patience.;To develop a measure of patience an item pool was …

Dynamic Response Evaluation Of Fiber-Reinforced Composite Bridge Decks And Bridges, Chandra Sekhar Jinka
Dynamic Response Evaluation Of Fiber-Reinforced Composite Bridge Decks And Bridges, Chandra Sekhar Jinka
Graduate Theses, Dissertations, and Problem Reports
Fiber Reinforced Polymer (FRP) composite bridge decks are gaining attention of bridge owners because of their light self weight, corrosion resistance and ease of installation. The lighter weight and lower stiffness of the FRP decks combined with the lower level of damping (than concrete) can lead to excessive deck vibrations and may substantially increase the dynamic amplification of induced stress and deflections. Also, a global NDE technique using dynamic characterization is necessary to ensure the long term performance of FRP bridges. Therefore, an extensive study on FRP decks and FRP bridges is carried out both at laboratory and in the …
Laboratory Experiments In Thermal Sciences, Christopher K. Jackson
Laboratory Experiments In Thermal Sciences, Christopher K. Jackson
Graduate Theses, Dissertations, and Problem Reports
Study of the basic sciences (chemistry, biology, physics, etc.) requires experimental verification to support the theory developed in the classroom. Engineering solutions are the same in their need for verification. In an academic environment this verification comes in the form of laboratory courses. The link to applications is equally important as the demonstration of theory. This is especially true for engineering disciplines due to the nature of tasks engineers are expected to successfully complete in industry. It is vital for the engineer's career that he/she can successfully apply the background theory learned in university study to real world applications.;The Department …
Cerulean Warbler Relative Abundance And Frequency Of Occurrence Relative To Large-Scale Edge, Scott B. Bosworth
Cerulean Warbler Relative Abundance And Frequency Of Occurrence Relative To Large-Scale Edge, Scott B. Bosworth
Graduate Theses, Dissertations, and Problem Reports
Cerulean Warblers (Dendroica cerulea) were studied in southwestern West Virginia where the coal mining technique of mountaintop mining/valley fill (MTMVF) continues to perforate large contiguous tracts of deciduous forest. My study objectives were to (1) quantify abundance and probability of occurrence of Cerulean Warblers relative to distance from large-scale edge (defined as reclaimed MTMVF sites) and (2) relate habitat structure and landscape characteristics to the species' probability of occurrence. Cerulean Warbler abundance increased significantly (P < 0.10) with distance from reclaimed mine edge. However, percent occurrence relative to distance from mine edge was not significant, suggesting a degree of tolerance to the large-scale edge created by MTMVF. Abundance was significantly greater on ridges than bottomlands. Percent occurrence did not differ among the three slope positions but followed a trend similar to abundance. Consequently, disturbances such as MTMVF in which ridges are removed may have a greater impact on populations compared to other sources of fragmentation where ridges are not disturbed. Other habitat structure analyses suggest good indicators of Cerulean Warbler presence are the more productive sites on northwest to east facing slopes and low sapling density. Similarly, Cerulean Warbler abundance was positively associated with more productive sites and snag density. Important landscape characteristics positively associated with abundance were large blocks of mature deciduous forest and low edge density. Mountaintop mining/valley fill alters the spatial configuration of forested habitats in southwestern West Virginia, thus creating less suitable habitat and edge effects that negatively affect Cerulean Warbler abundance, occurrence, and distribution in the reclaimed mine landscape.

Investigation Of Initiation Of Reverse Transcription In Retroviruses Using Vectors With Two Primer -Binding Sites, Yegor A. Voronin
Graduate Theses, Dissertations, and Problem Reports
Initiation of reverse transcription in retroviruses occurs on a specific place in viral genome, called primer-binding site (PBS). Cellular tRNA is annealed to the complementary PBS and is used as a primer. We constructed murine leukemia virus (MLV)-based vectors containing two PBSs, one in normal position and another in the middle of the vector. Green fluorescence protein (GFP) gene was inserted between the two PBSs. The internal PBS was derived from a spleen necrosis virus (SNV), which uses the same tRNA-Pro as a primer. We have shown that the internal PBS was functional for initiation of reverse transcription. Replication of …

Evaluation Of Concrete Median Barrier Delineation Under Poor Visibility Conditions, Kari A. French
Graduate Theses, Dissertations, and Problem Reports
A nationwide survey, durability test, and visibility test were conducted for concrete median barrier delineation. PENNDOT was encountering with delineators becoming detached due to harsh conditions in the roadside areas, as well as visibility problems in spot locations prone to fog. From the results of the research it was recommended that in areas prone to poor visibility conditions, PENNDOT consider decreasing the longitudinal spacing and providing delineation lower on the barrier than shown in the standards. With respect to the durability, in instances where the "peel-n-stick" delineators are comparable in price to obtaining the delineator and adhesive separately, that special …

Fungi Associated With Northern Red Oak (Quercus Rubra ) Acorns, Dawn M. Washington
Graduate Theses, Dissertations, and Problem Reports
Poor regeneration of northern red oak is widespread in the central hardwood region. A two-part study was conducted to determine what fungi are associated with and cause cotyledon discoloration of northern red oak acorns. The field study determined that simulated small mammal notching, surface sowing, time, and site all play a significant role in the amount of cotyledon discoloration in acorns as well as the number of acorns with discoloration. However, germination rate was only affected by site and surface sowing, while seedling vigor ratings were actually higher when acorns had discolored cotyledons. The five species of fungi isolated most …
