The Effect Of Ovine Peripheral Blood Mononuclear Cells On Haemonchus Contortus Larval Death In Vitro, Elizabeth Anne Shepherd Jan 2016

The Effect Of Ovine Peripheral Blood Mononuclear Cells On Haemonchus Contortus Larval Death In Vitro, Elizabeth Anne Shepherd

Graduate Theses, Dissertations, and Problem Reports (ETD)

Gastrointestinal nematode parasitism is the greatest problem facing small ruminant livestock, largely due to development of anthelmintic resistance. Of particular concern is Haemonchus contortus, a hematophagous trichostrongylid that can lead to death in lambs or immunocompromised sheep. Some breeds of sheep are resistant to Haemonchosis, e.g. St. Croix (STC) hair sheep. St. Croix sheep have well-documented resistance and have been shown to develop a robust immune response, generating a rapid cellular response to larval stages that does not occur in susceptible sheep. Studies evaluating effects of mononuclear cells, including monocytes and lymphocytes, indicate that these cells dramatically reduce motility of …

Brook Trout (Salvelinus Fontinalis) Preference Of Aquatic Versus Terrestrial Prey In Appalachian Headwater Streams, Erin E. Thayer

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis aims to investigate the foraging behavior of Brook Trout (Salvelinus fontinalis), specially focusing on prey preference. Brook Trout are mainly restricted to head-water streams in Appalachia, which is a portion of their native range. These environments generally have low autochthonous materials. Therefore, resident aquatic organisms rely heavily on terrestrial inputs, i.e. leaf litter and terrestrial invertebrates (TI's), to subsidize individual energy requirements at critical times of the year. There is mixed evidence demonstrating stream dwelling trout show either a feeding preference towards aquatic invertebrates (AI's) or towards TI's. Chapter one is an in depth literature review of headwater …

Real-Time Monitoring And Prediction Of The Pilot Vehicle System (Pvs) Closed-Loop Stability, Tanmay Kumar Mandal

Graduate Theses, Dissertations, and Problem Reports (ETD)

Understanding human control behavior is an important step for improving the safety of future aircraft. Considerable resources are invested during the design phase of an aircraft to ensure that the aircraft has desirable handling qualities. However, human pilots exhibit a wide range of control behaviors that are a function of external stimulus, aircraft dynamics, and human psychological properties (such as workload, stress factor, confidence, and sense of urgency factor). This variability is difficult to address comprehensively during the design phase and may lead to undesirable pilot--aircraft interaction, such as pilot-induced oscillations (PIO). This creates the need to keep track of …

Critical Analysis Of Longwall Ventilation Systems And Removal Of Methane, Robert B. Krog Jan 2016

Critical Analysis Of Longwall Ventilation Systems And Removal Of Methane, Robert B. Krog

Graduate Theses, Dissertations, and Problem Reports (ETD)

Bleeder systems are an important component for ventilation and the control of methane. The bleeder system of a coal mine contains a mixing zone for methane-laden air from the mined-out portions of the seam to mix with fresh air and the methane concentrations in the bleeders can often be elevated. Bleeders also provides a pathway for coalbed methane-laden ventilation air to quickly flow out of the mine through low resistance airways of a mine, such as supported gateroads, along the un-compacted outer perimeter of the gob, etc. Substantial quantities of coalbed methane are typically removed from underground workings. Although it …

Adjustment Of Bracket Position Away From The Andrew's Plane To Achieve A Flat Occlusal Plane, Jason M. Lawrence Jan 2016

Adjustment Of Bracket Position Away From The Andrew's Plane To Achieve A Flat Occlusal Plane, Jason M. Lawrence

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: "The Six Keys to Normal (Optimal) Occlusion" published by Andrews in 1972 identified six common features characteristic of an optimal occlusion. Among these characteristics are flat maxillary and mandibular occlusal planes. Andrews further developed the Straight-Wire Appliance(TM) to facilitate attaining an optimal occlusion in an efficient manner with few if any arch wire bends. In addition to the Six Keys, Andrews proposed that attaining a flat occlusal plane with a straight arch wire is predicated on siting the bracket slots on the FA Points of the tooth crowns (Andrews Plane).
