The β-Tubulin Gene As A Means To Discriminate Species And Verify Evolutionary Patterns Of Arbuscular Mycorrhizal Fungi., Zola Msiska
Graduate Theses, Dissertations, and Problem Reports (ETD)
Arbuscular mycorrhizal fungi (AMF) associating with 80% of vascular plant families increase uptake of nutrients and water in plants, help to stabilize soil aggregates and improve soil aeration, water percolation and carbon storage. Phylogeny of AMF based on rDNA sequences is in conflict with morphology-based phylogeny. The aim of the present study was to examine a protein encoding gene, β-tubulin, in order to test conclusions drawn from rDNA sequences and morphological data. Inverse-PCR was used to amplify full-length β-tubulin genes of Gigaspora gigantea and Glomus clarum. The gene in both species is organized into five exons and four introns encoding …
The Effect Of Follicular Aging On Gene Expression In Oocytes And Granulosal Cells., Brandon Michael Lingenfelter
The Effect Of Follicular Aging On Gene Expression In Oocytes And Granulosal Cells., Brandon Michael Lingenfelter
Graduate Theses, Dissertations, and Problem Reports (ETD)
Mammalian oogenesis usually occurs concomitantly with folliculogenesis, coordinated through paracrine effects and physical contacts. During this time, the oocyte acquires the ability to resume meiosis, undergo fertilization and sustain embryonic development. Synthesis of RNA occurs during oogenesis and is largely responsible for early embryonic development. Any perturbations that delay either activation or ovulation can result in early embryonic loss. Therefore, the interacting effects at the genomic level were investigated using a persistent follicle model. Experiment 1. The present study was conducted to analyze global gene expression profiles in granulosal cells from ovarian follicles in cows. Analysis of the microarray data …

The Stationary Alfven Wave In Laboratory And Space Regimes., S M. Finnegan
The Stationary Alfven Wave In Laboratory And Space Regimes., S M. Finnegan
Graduate Theses, Dissertations, and Problem Reports (ETD)
In this thesis, a non-linear, collisional, two-fluid model of uniform plasma convection across field-aligned current (FAC) sheets, describing stationary Alfven (StA) waves is developed in support of laboratory experiments performed to test the hypothesis that a stationary inertial Alfven wave pattern forms within a channel of parallel electron current across which plasma is convected. In a previous work, Knudsen (D. J. Knudsen, J. Geophys. Res. 101, 10,761 (1996)) showed that, for cold, collisionless plasma, stationary inertial Alfven (StIA) waves can accelerate electrons parallel to a background magnetic field and cause large, time-independent plasma-density variations having spatial periodicity in the direction …

Graduate Theses, Dissertations, and Problem Reports (ETD)
This thesis details the response of a land-grant university to the development of quantum mechanics and relativity across a forty-year period. Concurrently with this, it traces the pattern of normal research at the university to show how the development of new physical theories impacted a representative physics department. The Physics department at West Virginia University at first paid little attention to relativity then after 1924 rejected its theoretical underpinnings. Wholesale acceptance of the theory did not occur until after the replacement of the pre-World War II generation of physicists. Quantum mechanics did not make significant inroads at West Virginia University …
Response Rate Or Number Of Repetitions: Which Aspect Of Drill And Practice Testing Most Contributes To Paired-Associate Learning., Scott Davis
Graduate Theses, Dissertations, and Problem Reports (ETD)
Precision teaching methods began in the 1960s and have grown in utility and popularity over the last four decades (Downer, 2007). The methods are used to teach across multiple contents with an emphasis in achieving fluency as opposed to mere accuracy. Speed drills, frequently used to determine the learner's current level of fluency, were found to have a significant treatment effect on learning (McGreevy, 1978; Scott, Wolking, Stoutimore, & Harris, 1990; White & Haring, 1976). The purpose of this study is to isolate and measure the treatment effect of two key aspects of the speed drill and practice component of …

Application Of Lidar-Derived Dems And Their By-Products For Geomorphic Assessment From Stream-Reach To Watershed Scales: Horseshoe Run, Wv., Justin Beau Downing
Application Of Lidar-Derived Dems And Their By-Products For Geomorphic Assessment From Stream-Reach To Watershed Scales: Horseshoe Run, Wv., Justin Beau Downing
Graduate Theses, Dissertations, and Problem Reports (ETD)
The application of Digital Elevation Models (DEMs) for geomorphic assessment at a range of scales has increased over the past two decades. Before the advent of LiDAR, DEMs were generated using topographic maps or aerial photographs. The resulting grid-based DEMs generally had coarse resolutions ranging from 10 m to 30 m. Research has shown these resolutions to be acceptable when investigating large areas, but fail to provide adequate resolution for finer scale geomorphic assessment. LiDAR technology allows the creation of much finer resolution DEMs, ranging from 0.5 m to 6 m, depending on the sensor used. The Canaan Valley Institute …

Development Of A Micro-Depth Sensing Indentation Technique With Constant Load Control, Ailing Lin
Graduate Theses, Dissertations, and Problem Reports (ETD)
In material nano- and micro-indentation research, Young's modulus can be obtained based on the initial unloading stiffness of the load-depth curve. The accurate load and displacement measurement as well as high precision position control of the indenter are needed to achieve the required measurement resolution. The application of PZT actuator is often used to perform the indentation experiment. However, conventional PZT controllers can only provide displacement control. Furthermore, each PZT actuator only serves a specific PZT controller using its unique calibration factor. Thus, it is beneficial to develop a controller, which can carry out both load and displacement control algorithm, …

Discriminative-Stimulus And Time-Course Effects Of Kava-Kava (Piper Methysticum) In Rats, Natalie R. Bruner
Graduate Theses, Dissertations, and Problem Reports (ETD)
Kava-kava is a widely available and used herbal medicine that is not regulated in many countries, including the United States. There are many questions concerning kava-kava's stimulus properties, potential for therapeutic use, and potential for abuse. Although there is evidence that kava may possess some anxiolytic properties, the supplement's mechanism of action and the extent to which it may serve as an alternative to pharmaceutical anxiolytics are unknown. To date, there is no research examining whether kava shares discriminative-stimulus properties with a standard pharmaceutical anxiolytic such as chlordiazepoxide (CDP). The current study compared different doses of kava in two groups …
Aerodynamic Benefits Of Near-Surface-Actuated Circulation Control Blowing Slots For Rotorcraft Use, Gerald M. Angle Ii
Aerodynamic Benefits Of Near-Surface-Actuated Circulation Control Blowing Slots For Rotorcraft Use, Gerald M. Angle Ii
Graduate Theses, Dissertations, and Problem Reports (ETD)
One of the most maintenance intensive components of all present-day helicopters is the swash-plate, and its associated control linkages. This mechanism is also the major contributing factor to fatal accidents associated with helicopter flight. However, the swash-plate is an essential component in providing controlled flight, by transmitting the pilot's control-inputs to the main rotor. Another side-effect of using the swash-plate is that it increases the diameter of the main rotor shaft assembly, slightly increasing the total drag of the aircraft. Thus, there are several benefits that could be achieved by removing the swash-plate of the helicopter.;To enable the removal of …
