Vulture Flight Behavior Driven By Uplift Availability At Local And Continental Scales, Julie Mallon Jan 2015

Vulture Flight Behavior Driven By Uplift Availability At Local And Continental Scales, Julie Mallon

Graduate Theses, Dissertations, and Problem Reports (ETD)

Understanding how animals move in response to their environment is a fundamental question in ecology. Soaring species, which rely on environmentally generated uplift to forage and migrate, should be especially sensitive to changing weather and climatic conditions. Changes in uplift distribution or strength can have energetic implications and restrict movement capacity for soaring species. Poor weather conditions can shorten foraging time or slow migration progress. To increase mobility, birds can switch to flapping or soar using another uplift type. Use of uplift, however, is associated with certain flight altitudes and movement speeds. Switching uplift types will affect a bird's ecological …

Suicidal Ideation, Attempts, And Associated Psychosocial Risk And Protective Factors In American Indian Youth And Young Adults, Karen Manzo Jan 2015

Suicidal Ideation, Attempts, And Associated Psychosocial Risk And Protective Factors In American Indian Youth And Young Adults, Karen Manzo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction. Research consistently shows that suicidal ideation and attempts are more prevalent among American Indian youth and young adults than youth and young adults in other racial/ethnic groups. Many of the associated psychosocial risk and protective factors are shared across racial/ethnic groups; however, for most of them, the prevalence is highest in American Indian youth. Research on the relation between suicide risk and culturally unique risk (e.g., childhood adversity, discrimination, parenting, unresolved grief, out-of-home placement) and protective factors (e.g., enculturation, cultural values, spirituality) in American Indian youth and young adults is limited. The goal of this research was to examine …

Analgesic And Anti-Inflammatory Effects Of Monoacylglycerol Lipase Inhibition In Mice Subjected To Collagen-Induced Arthritis, Sara R. Nass

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rheumatoid arthritis (RA) is the most prevalent chronic inflammatory joint disease, affecting approximately 1% of the world population. This autoimmune disease is characterized by pain, stiffness, swelling, and breakdown of cartilage in synovial joints. Current RA analgesic treatments (i.e., pain reducing drugs) are ineffective or induce negative side effects, and so there are many concerted efforts to discover new RA treatments. Cannabinoids have analgesic and anti-inflammatory properties; however, the challenge remains to harness the medical potential of cannabinoids without inducing negative psychoactive effects (e.g., cognitive deficits, emotional disruption, and abuse potential). An alternative approach focuses on the endogenously produced cannabinoids …

Evaluation Of The Antidepressant Potential Of Dextromethorphan, Linda Nguyen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Depression affects more than 350 million people and is the leading cause of disability worldwide. Major challenges in the management of depression remain the 4-12 weeks of delayed efficacy and 30% of patients who are resistant to the therapeutic effects of current pharmaceutical treatments. We herein examined whether dextromethorphan (DM) may be able to take on these challenges, because 1) it has overlapping pharmacology with ketamine, which has shown rapid (within 24 hours) antidepressant effects, even in treatment-resistant individuals; 2) unlike ketamine with its notable abuse liability and adverse effects, DM is an over-the-counter antitussive with a high safety margin; …

Variable Data Collection Rate System For A Wildlife Behavior Monitor, Sheldon Blackshire Jan 2015

Variable Data Collection Rate System For A Wildlife Behavior Monitor, Sheldon Blackshire

Graduate Theses, Dissertations, and Problem Reports (ETD)

Behavior monitors typically collect data, and consequently spend energy, at fixed intervals. For devices that utilize energy harvesting, a fixed data collection interval may result in inefficient battery usage due to variability in available solar radiation. Work was performed for a system capable of adjusting a data collection rate, proportional to changes in battery charge, such that data obtained was maximized without sacrificing battery energy sustainability. Energy consumption, of an actual behavior monitor, was modeled to aid in design and evaluation of a changeable data collection rate system. Model validation was performed by comparing simulated to empirical data for battery …

Myosin Ii Isoforms In Breast Cancer: Role Of Contractility In Matrix Organization, Cell Migration, And Endothelial Barrier Function, Bridget Ruth Hindman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Breast cancer is a devastating and complicated disease. A large proportion of breast cancer related deaths are due to metastasis. Metastasis is when cancer cells leave the primary tumor, travel through the bloodstream, and proliferate in distant sites. Cell contractility is involved in a number of cellular processes associated with metastasis including matrix organization, tumor cell migration, and endothelial cell barrier function. The main regulator of contractility in nonmuscle cells is nonmuscle myosin II. There are three isoforms of this protein: myosin IIA, IIB, and IIC. The specific roles of the individual isoforms in cancer progression and metastasis have yet …

Functional Analysis And Transcriptional Regulation Of Oocyte-Specific Nuclear Transporter Kpna7, Lei Wang

Graduate Theses, Dissertations, and Problem Reports (ETD)

The finely orchestrated development and maturation of the oocytes has been the focus of many studies in which oocyte-specific genes essential for folliculogenesis and early embryonic development have been identified. Studies using knockout mice models of Nobox, Sohlh1, Sohlh2, Figla and Lhx8 have revealed that these oocyte specific transcriptional factors form networks in which they regulate the expression of each other and downstream targets. However, little is known about the mechanisms that control the nuclear transport of these essential factors in oocytes and early embryos. The nuclear envelope separates the nuclear and cytoplasmic compartment in the cell and uncouples transcription …

Avoidance Of Token-Loss By Pigeons, James E. Cook Jan 2015

Avoidance Of Token-Loss By Pigeons, James E. Cook

Graduate Theses, Dissertations, and Problem Reports (ETD)

The response-dependent delivery and removal of tokens can reinforce and punish the responding of humans and nonhuman animals. The responding of humans can be maintained by the avoidance of token-losses, but this has not been demonstrated with nonhuman animals. Across three experiments, it was demonstrated that the responding of pigeons could be maintained in a token-loss avoidance arrangement. Tokens were delivered response-independently at the beginning of a token-loss avoidance period. Tokens were scheduled to be removed on a variable-cycle schedule. Responding canceled scheduled token-losses. Those tokens that remained were exchangeable for food during programmed exchange periods. Several parameters of the …

Lumbar Posture And Tissue Loading During Short-Term Static Trunk Bending, Faisal Alessa

Graduate Theses, Dissertations, and Problem Reports (ETD)

Low back pain (LBP) is among the most prevalent occupational health problems worldwide and is a leading cause of lost work days. Previous studies have suggested that static prolonged trunk bending could generate lumbar muscle fatigue and introduce creep to the lumbar posterior tissues. Such physical changes could lead to alterations to the lumbar active and passive tissue sharing mechanism and also elevate spinal loading, which is highly associated with the risk of LBP. In the past, most occupational ergonomic studies focused on the instantaneous spine biomechanical responses during task performance. A few studies assessed the changes of spine biomechanics …

The Effects Of Modest Improvement In Pellet Quality On Tom Turkey And Straight-Run Broiler Performance, With Focus On Experimental Design, Brian Gregory Glover Jan 2015

The Effects Of Modest Improvement In Pellet Quality On Tom Turkey And Straight-Run Broiler Performance, With Focus On Experimental Design, Brian Gregory Glover

Graduate Theses, Dissertations, and Problem Reports (ETD)

Improving the crumble/pellet percentage of feed has been argued to be difficult to obtain in the commercial industry due to the necessity of feed mills producing adequate feed volume within a time constraint. Poultry research often utilizes small numbers of birds per pen or experimental unit that may affect the estimation of variance components, potentially producing pen performance metrics that are less valuable for industry guidance. In Experiment 1, diets were manufactured to maintain nutrient availability and vary only in crumble/pellet percentage (standard = 40% pellets, improved = 70% pellets). The two dietary treatments were then fed to Hybrid Converter …
