Neuronostatin Acts In Brain To Biphasically Increase Mean Arterial Pressure Through Sympatho-Activation Followed By Vasopressin Secretion: The Role Of Melanocortin Receptors, Gina L.C. Yosten, Alicia T. Pate, Willis K. Samson

Biological Sciences Faculty Research & Creative Works

Neuronostatin is a recently described neuropeptide that is derived from the somatostatin preprohormone. We have shown previously that neuronostatin led to a biphasic, dose-related increase in mean arterial pressure when injected into the lateral cerebroventricle of adult, male rats. Because neuronostatin depolarized both magnocellular and parvocellular, paraventricular nucleus neurons in hypothalamic slice preparations, we hypothesized that neuronostatin elevated mean arterial pressure first by stimulating sympathetic nervous system activity followed by the release of a pressor hormone, specifically vasopressin. We found that the first phase of neuronostatin-induced increase in mean arterial pressure was reversed by pretreatment with phentolamine, indicating that phase …

Simultaneous Measurement Of Normal And Friction Forces Using A Cantilever-Based Optical Interfacial Force Microscope, Byung I. Kim, Jeremy R. Bonander, Jared A. Rasmussen

Physics Faculty Publications and Presentations

We measured normal and friction forces simultaneously using a recently developed cantilever-based optical interfacial force microscope (COIFM) technique for studies of interfacial structures and mechanical properties of nanoscale materials. We derived how the forces can be incorporated into the detection signal using the classical Euler equation for beams. A lateral modulation with the amplitude of one nanometers was applied to create the friction forces between tip and sample. We demonstrated its capability by measuring normal and friction forces of interfacial water at the molecular scale over all distance ranges.

Cuttlefish Learning Efficiency In A Food Retrieval Task, Jasmine Schonwald

Biology Theses

Class Cephalopoda is thought to contain the most intelligent invertebrates thus far discovered. It has been found that cuttlefish have the capacity for learning (Boal et al. 2000, Darmillaq et al. 2003, Darmillaq et al 2006, Graindorge et al., 2006; Karson, Boal and Hanlon, 2003). It has also been shown that cuttlefish can navigate in sophisticated ways, such as within a maze (Graindorge, et al., 2006; Karson, Boal and Hanlon, 2003). The goal of this experiment is to determine the correlation between learning and navigation in cuttlefish. Cuttlefish were placed in an oval tank divided into …

Developing Mechanisms For The Transfer And/Or Adjustment Of Rock Lobster Shares Between Sectors In Western Australia And South Australia., Chris Reid

Fisheries Management Papers

The purpose of this report has been to investigate potential reallocation mechanisms for the transfer and/or adjustment of catch shares between sectors and the requirements to allow for their implementation, with particular reference to their application in the Western and South Australian rock lobster fisheries. While the report focuses on the commercial and recreational sectors of these fisheries, potentially all non-commercial fishing sectors could be included under a given mechanism in the same manner as that outlined for the recreational sector, subject to the appropriateness of allowing the sector’s allocation to be transferable

The Effects Of Alcohol Based Cues Virtual Reality Versus Guided Imagery, Nicole Labriola

HIM 1990-2015

The use of Virtual Reality (VR) and Imagery have been utilized in psychological practices and treatment. VR has recently been the focus of research with treatments for post traumatic stress disorder, substance abuse, and phobias, among other social and behavioral issues. VR allows the researcher to create realistic controlled environments in which they are able to manipulate the experiment. Imagery permits the individual to imagine and recall scenarios from their past in order to create a more personal environment. This experiment aimed to expand upon VR practices and treatment in regards to alcohol research. In this experiment, 70 participants, 39 …

A Comparative Review Of The Works Of Feldman, Sternberg, Gardner And Eisner And The Resulting Practical Application For The Secondary Art Classroom, Heather Denmark

HIM 1990-2015

Some fields come and go, but there will always be a need for older generations to teach the younger generations. For this reason, teachers will always be needed. The material that they choose to teach can sometimes determine the outcome of a nation. Take a look into German and Roman histories; they are littered with teachers convincing students that their way is right. I think that it is imperative that we research the full potential of what we are teaching our students. For that reason, my thesis will consist of analyzing and synthesizing the research of Feldman, Sternberg, Gardner and …

Angelu Demonai, Caitlin Leigh Halvorson

Senior Theses

This project has been a long time in the making. The concept originated several years ago, and what was once just the shadow of a character has morphed into the story you see today - the makings of a graphic novel about one rock musician’s quest to discover herself, and save the worlds in the process.

Of course, you will only see a small part of the story. What is included in this thesis project is only the first volume of several (four, I expect). And while the journey is not yet completed, the ride has been thrilling so far. …

Amphibian Adaptability To Habitat Transformation And The Effect Of Rainfall During The Dry Season On Their Activity Pattern, May 2011, Amber Brossard

Monteverde Institute: Tropical Ecology and Conservation

Amphibians are being forced to change their habits and lifestyles to adapt to human transformations. Some species of amphibians are becoming dependent on man-made ecosystems to carry out their life cycles. Also, climate change is affecting the seasonality by changing the amount of precipitation and the phenology of amphibians. This study was conducted in San Luis Costa Rica in an area characterized by a pre-montane wet forest during the dry season (April 2011). Pitfall traps and drift fences were set up in a forest location and in a man-made pond location to compare the number species within each location. Rainfall …

Aquatic Macro-Invertebrate Community Composition Differences Between The Atlantic And Pacific Watersheds In Monteverde, Costa Rica, May 2011, Tim Curry

Monteverde Institute: Tropical Ecology and Conservation

There are large differences between slope seasonality in Monteverde, Costa Rica. The Pacific slope receives less rainfall, and has a better-defined wet and dry season. This study looked at how these differences affect aquatic benthic macro-invertebrates composition. Five different rivers were sampled, three on the Atlantic slope, and two on the Pacific slope. There was no significant difference between the two slopes in species richness, evenness, or number of species. There were differences in species composition between the two slopes. This study exemplifies how areas in close proximity can have different species compositions. For conservation purposes, this study demonstrates how …

Pollination Syndrome And Nectar Protection In Brugmansia Suaveolens (Solanaceae), May 2011, Elizabeth Mejicano

Monteverde Institute: Tropical Ecology and Conservation

Specialization between plant and pollinator species has resulted in the development of pollination syndromes in which suites of floral traits attract specific pollinators. While plants use nectar as a reward to attract pollinators, they must also defend themselves, either chemically or morphologically, against nectar robbers. Brugmansia (formerly Datura; Solanaceae) has been described as possibly sphingid, hummingbird, bee, or bat pollinated, underscoring how little is known about pollination in this genus. It is also heavily protected chemically, including the flowers. One aim of this study was to examine floral traits and compare them to known pollination syndromes to determine the most …

Economic Impacts Of Drought On Kentucky Corn, Hay, And Soybeans, Kortney E. Craft

Masters Theses & Specialist Projects

Understanding climatic impacts is important if we are to comprehend the relationship between climate and society. Weather phenomena can have environmental, economical, and social impacts. Drought is the natural hazard that affects people the most. It is also the most complex and least understood. There is no one universally accepted definition for drought which makes its examination difficult. Droughts’ duration is also difficult to determine because it has no clearly defined onset and end. Also, drought varies both geographically and temporally making uniform drought monitoring difficult. Since drought is difficult to monitor and access, drought impacts are often poorly documented. …

Sensory Evaluations Of Usda Select Strip Loin Steaks Enhanced With Sodium And Potassium Phosphates And Usda Choice Strip Loin Steaks For Comparable Palatability Factors, Lindsey Reynolds

Masters Theses & Specialist Projects

The cyclic nature of the beef industry is dependent on the supply and demand transaction initiated by consumers’ acceptability of quality meat products. When purchasing beef at the grocery store, consumers are dependent on USDA grades and visual appraisal; consumers expect consistency in products. Upon this appraisal, quality is determined by the color, marbling content, and texture of a particular retail cut, as well as cooked characteristics of tenderness, flavor, and juiciness. Variability in meat tenderness is a major quality defect of beef (Morgan et al., 1991b; Smith et al., 1992). A common practice used by beef processors to extend …

Biological Sciences Faculty Publications

Agricultural and urban development alters nitrogen and other biogeochemical cycles in rivers worldwide. Because such biogeochemical processes cannot be measured empirically across whole river networks, simulation models are critical tools for understanding river-network biogeochemistry. However, limitations inherent in current models restrict our ability to simulate biogeochemical dynamics among diverse river networks. We illustrate these limitations using a river-network model to scale up in situ measures of nitrogen cycling in eight catchments spanning various geophysical and land-use conditions. Our model results provide evidence that catchment characteristics typically excluded from models may control river-network biogeochemistry. Based on our findings, we identify important …

Noninvasive Mri Measures Of Microstructural And Cerebrovascular Changes During Normal Swine Brain Development, Jeff D. Winter, Stephanie Dorner, Jelena Lukovic, Joseph A. Fisher, Keith S. St. Lawrence, Andrea Kassner

Paediatrics Publications

The swine brain is emerging as a potentially valuable translational animal model of neurodevelopment and offers the ability to assess the impact of experimentally induced neurological disorders. The goal for this study was to characterize swine brain development using noninvasive MRI measures of microstructural and cerebrovascular changes. Thirteen pigs at various postnatal ages (2.3-43.5 kg) were imaged on a 1.5-Tesla MRI system. Microstructural changes were assessed using diffusion tensor imaging measures of mean diffusivity and fractional anisotropy. Cerebrovascular changes were assessed using arterial spin labeling measures of baseline cerebral blood flow (CBF) and the cerebrovascular reactivity (CVR) of the blood-oxygen …

Analytic And Numerical Studies Of A Simple Model Of Attractive-Repulsive Swarms, Andrew S. Ronan

HMC Senior Theses

We study the equilibrium solutions of an integrodifferential equation used to model one-dimensional biological swarms. We assume that the motion of the swarm is governed by pairwise interactions, or a convolution in the continuous setting, and derive a continuous model from conservation laws. The steady-state solution found for the model is compactly supported and is shown to be an attractive equilibrium solution via linear perturbation theory. Numerical simulations support that the steady-state solution is attractive for all initial swarm distributions. Some initial results for the model in higher dimensions are also presented.

Bitter-Sweet Home: The Pastoral Ideal In African-American Literature, From Douglass To Wright, Robyn Merideth Preston-Mcgee

Dissertations

Discussions of the pastoral mode in American literary history frequently omit the complicated relationship between African Americans and the natural world, particularly as it relates to the South. The pastoral, as a sensibility, has long been an important part of the southern identity, for the mythos of the South long depended upon its association with a new “Garden of the World” image, a paradise dependent upon slave labor and a racial hierarchy to sustain it. For African Americans, the rural South has been both a home and a place of violence and oppression, particularly during the period of slavery through …

"Reading" The Apprentice: Commerce, Culture, And The Manufacturing Of Reality, Sharon Simpson Terrell

Dissertations

This study examines the six original seasons of the reality television series The Apprentice as a postmodern, cultural artifact. Grounded in Burke’s (1967) “literature as equipment for living,” and Brummett’s (1984) consideration that televised content constitutes literature, the theory of “televised discourse as equipment for living” provided the guide to examine the series. Hall’s (1980) “reading against the grain” oppositional reading technique was utilized to interrogate both the manifest and latent content. The content of the series may indeed provide the audience with a guide to ideological beliefs of both commerce and culture, thereby creating a manufactured reality for its …

The Influence And Legacy Of Deism In Eighteenth Century America, Tiffany E. Piland

Master of Liberal Studies Theses

This thesis project, The Influence and Legacy of Deism in Eighteenth Century America, examines deism’s impact as a theological system on American life and culture in the eighteenth century. Beginning with a basic definition of the term deism, a historical background is included. Next, the work of Galileo, Bacon, Newton, and Locke is examined for its impact on eighteenth century thought as well as early deist writers such as John Toland, Matthew Tindal, and Lord Herbert of Cherbury.

Moving onto America in the eighteenth century, colonial newspaper articles, letters, and other documents are examined that contain references to deism. Colleges …

Evil: Genocide In The 21st Century, James L. Pigmon

Master of Liberal Studies Theses

This paper will explore commonalities and processes that led to genocide in the twentieth century. Information from four notable genocides will be used to determine the feasibility of genocide continuing unabated into the twenty first century. Armenian, Holocaust, Cambodian and Rwandan genocides have similar qualities establishing a “recipe” for others to use as a template or as a predictor of the next genocide. This thesis will use psychological theory, case studies and historical data to formulate reasons why individuals can be easily persuaded to take on the role as perpetrator. Has the international community done enough to either prevent or …

Rule Britannia: Britain, Breadfruit, And The Birth Of Transoceanic Plant Transportation, Annabel Tudor

Master of Liberal Studies Theses

This paper examines the events that precipitated transoceanic plant transportation and British imperial expansion during the second half of the eighteenth century. Combined circumstances forced the British to explore transoceanic plant transportation to make colonies, especially those in the British West Indies, more self-sufficient. Hurricanes in the Caribbean destroyed ground crops vital for slaves and plantation operations, and fallout from a volcanic eruption in Iceland poisoned soil in Britain and northern Europe for years. Wars with France and America inhibited oceanic trade and trade routes. These circumstances fostered the British desire to control its own food supply and resulted in …
