Nerve Fiber Diameter Measurements Using Hematoxylin And Eosin Staining And Brightfield Microscopy To Assess The Novel Method Of Characterizing Peripheral Nerve Fiber Distributions By Group Delay, Jorge Arturo Vazquez

Master's Theses

Peripheral neuropathies are a set of common diseases that affect the peripheral nervous system, causing damage to vital connections between various parts of the body and the brain and spinal cord. Different clinical conditions are known to selectively impact various size nerve fibers, which often makes it difficult to diagnose which peripheral neuropathy a patient might have. The nerve conduction velocity diagnostic test provides clinically useful information in the diagnosis of some peripheral neuropathies. This method is advantageous because it tends to be minimally invasive yet it provides valuable diagnostic information. However, this test does not determine characteristics of peripheral …

Treatment Of Nitrogen Oxides By Chlorella Vulgaris Algae In Photobioreactors, Steven Shihady

Master's Theses

The effectiveness of algae to treat NO₂and NO in simulated flue gas was tested using Chlorella vulgaris in photobioreactors (PBRs) using NO_xconcentrations between 30 ppm to 780 ppm. NO_xdissolved and reacted in water to form NO₃^-and NO₂^-in the PBR growth medium, providing a nitrogen source that the algae readily assimilated for cell synthesis. Three 20-L photobioreactors were inoculated with a pure culture of C. vulgaris prepared in Bristol growth medium and algae were grown in the PBRs at 25°C and pH of 7.0 in a modified Bristol medium …

Behavioral And Hormonal Flexibility Across Light Environments In Guppies (Poecilia Reticulata), Julia C. Walz

Master's Theses

Behavior may be dramatically influenced by changing environments, and differences in light intensity environments may have important behavioral consequences. One approach to understanding changes in behavior is by studying behavioral syndromes, suites of correlated behaviors reflecting between individual consistencies in behavior expressed within a behavioral situation (e.g., correlations between antipredator behaviors in different habitats), or across behavioral contexts (e.g., correlations among feeding, antipredator, or mating behavior) (Sih et al. 2004a). Guppies (Poecilia reticulata) provide a great model system to study behavior. Guppies are small, freshwater tropical fish that inhabit still pools in swift-flowing streams, and the backwaters of small rivers …

Delineating Wetlands In Serpentinitic Soils, Ariel Nikole Namm

Master's Theses

Wetlands serve an important ecological and functional role in the environment. In order to protect wetlands from degradation, the determination of wetland hydrology, hydrophytic vegetation, and hydric soils is necessary. Soils formed from serpentine parent material on hillside slump blocks do not meet any of the current morphological Field Indicators of Hydric Soils. Although these areas seem to be wetlands based on wetland hydrology and hydrophytic vegetation, there is no approved hydric soil indicator that includes the properties exhibited by serpentinitic soils on these landscapes. The objectives of this research were: (1) to examine soil chemical, physical, and morphological properties …

Effects Of Water Parameters On Container Mosquito (Diptera: Culicidae) Oviposition And Performance, Stephanie Sue Schelble

Master's Theses

Water body parameters have a considerable effect on the communities that develop within them. In small container habitats like tires, the depth, surface area, and volume effect the development and success of the mosquito communities. This study investigated the choices of the adult female mosquitoes, Aedes albopictus and Culex quinquefasciatus, between different depths and surface areas. In addition, larval performance was determined under differing depth and larvae densities. Oviposition studies showed that Ae. albopictus had a preference for deeper habitats (χ²= 14.2902, p= 0.0139) but did not prefer any surface areas (χ²= 7.2321, p= 0.0649) though …

A Study Of The Variability Versus The Assumed Constancy Of Manning's N, Tyler G. Allen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Culverts have traditionally been designed to a minimal size to pass a specific design flood. The traditional culvert designs may result in a localized increase in velocity which can result in a blockage of animal or fish movement across a barrier effectively changing the ecosystem surrounding a number of affected species. While hydraulic loss coefficients are relatively well defined for such traditional culverts, the National Cooperative Highway Research Program (NCHRP) identified a need for further study of these coefficients for culverts more conducive to fish and animal passage.

Marine Science Faculty Publications

Over 1.3 billion people live on tropical coasts, primarily in developing countries. Many depend on adjacent coastal seas for food, and livelihoods. We show how trends in demography and in several local and global anthropogenic stressors are progressively degrading capacity of coastal waters to sustain these people. Far more effective approaches to environmental management are needed if the loss in provision of ecosystem goods and services is to be stemmed. We propose expanded use of marine spatial planning as a framework for more effective, pragmatic management based on ocean zones to accommodate conflicting uses. This would force the holistic, regional-scale …

The Effect Of Acute Lps-Induced Immune Activation And Brain Insulin Signaling Disruption In A Diabetic Model Of Alzheimer's Disease, Andrew Scott Murtishaw

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alzheimer's disease (AD) is a neurodegenerative disorder marked by progressive cognitive impairments and pathological hallmarks that include amyloid plaques, neurofibrillary tangles, and neuronal loss. Several well-known mutations exist that lead to early-onset familial AD (fAD). However, these cases only account for a small percentage of total AD cases. The vast majority of AD cases are sporadic in origin (sAD) and are less clearly influenced by a single mutation but rather some combination of genetic and environmental risk.

The etiology of sAD remains unclear but numerous risk factors have been identified that increase the chance of developing AD. Among these risk …

Evaluation Of Video Prompting To Teach Students With Intellectual Disabilities To Use A Cell Phone, Allenda Tharel Zionch

UNLV Theses, Dissertations, Professional Papers, and Capstones

For students with ID communication cannot be taken for granted. Not only is it vital that students with ID be able to express their wants and needs on a daily basis, but communication is paramount in order to express ideas and consider options for their future as well as to build and maintain friendships. These are important elements for a successful transition from school to adulthood.

Ninety-five percent of adults without disabilities between the ages of 18-34 own cell phones compared to twenty-eight percent of adults with ID. This disparity is due in part to lack of access, training and …

Brain and Mind Institute

Adipose tissue metabolism is a critical regulator of adiposity and whole body energy expenditure; however, metabolic changes that occur in white adipose tissue (WAT) with obesity remain unclear. The purpose of this study was to understand the metabolic and bioenergetic changes occurring in WAT with obesity. Wild-type (C57BL/6J) mice fed a high-fat diet (HFD) showed significant increases in whole body adiposity, had significantly lower V̇o2, V̇co2, and respiratory exchange ratios, and demonstrated worsened glucose and insulin tolerance compared with low-fat-fed mice. Metabolomic analysis of WAT showed marked changes in lipid, amino acid, carbohydrate, nucleotide, and energy metabolism. Tissue levels of …

Fluid Powered Miniature In Vivo Robots For Minimally Invasive Surgery (Mis), Abolfazl Pourghodrat

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Minimizing the invasiveness of surgery is believed to improve patient outcomes. Bleeding, infection, and pain are major concerns in surgery afflicting patients for decades. Minimally invasive techniques have come into play to reduce these concerns and smooth the evolution of abdominal surgery to a scarless process where nearly all surgeries can be performed without a skin incision. Technology continually advances the frontier of development of novel surgical devices to implement less invasive surgical techniques.

Fusion of robotics and Minimally Invasive Surgery (MIS) has created new opportunities to develop diagnostic and therapeutic tools. Surgical robotics is advancing from externally actuated systems …

Push-Pull: A Novel Ipm Strategy For The Green Revolution In Africa, Zeyaur R. Khan, Charles A.O. Midega, Jimmy O. Pittchar, John A. Pickett

All Peer-Reviewed Publications

Africa faces serious challenges in feeding its population, mainly due to poor yields of cereals that serve as both staple and cash crops occasioned by insect pests, weeds, and poor soil fertility, and more recently effects of climate change. A novel IPM approach dubbed push-pull has been developed and implemented in eastern Africa, based on locally available companion plants, that effectively addresses these constraints resulting in substantial grain yield increases. The technology involves intercropping cereal crops with stemborer moth repellent crops (push), the forage legume desmodium or molasses grass, and planting the attractive Napier grass (pull) as a border crop. …

Construction Of 3d Biomimetic Tissue Niches For Directing Pancreatic Lineage Differentiation Of Human Embryonic Stem Cells, Weiwei Wang

Graduate Theses and Dissertations

The potential of human embryonic stem cells (hESCs) to differentiate into insulin producing beta cells offers great hope for cell-based therapy for diabetes treatment. However, in vitro pancreatic differentiation of hESCs remains challenging. In the past decade, most protocols for differentiating pancreatic cells have been focused on the use of signaling molecule cocktails on 2D substrates. Studies on embryonic development biology strongly suggest that extracellular matrix (ECM) plays a critical role on hESCs behavior. In this work, we first established a 3D collagen scaffold culture system for hESCs differentiating into definitive endoderm (DE), which is the first and most important …

How Microlending Affects Innovation And Entrepreneurship: Evidence From Ethiopia, Robert Hirth

Graduate Theses and Dissertations

Advocates of microlending suggest it is a sustainable intervention that reaches the poor directly and offers them the means to invest and improve their incomes (Khavul, 2010; Morduch, 1999; Yunus, 2007); yet, impact studies of these interventions have suggested they often have little or even a detrimental impact on borrowers (Van Rooyen, Stewart & De Wet, 2012). This dissertation examines the efforts to promote entrepreneurship and alleviate poverty in developing countries through microlending. I begin by reviewing the microlending literature, and in particular, impact studies of the effect microlending is having in developing countries. Next, I review theory and empirical …

Predictive Model Development For Adsorption Of Organic Contaminants By Carbon Nanotubes, Onur Apul

All Dissertations

The main objective of the study was to investigate mechanisms and statistical modeling of synthetic organic contaminant (SOC) adsorption by carbon nanotubes (CNTs). First, predictive models were developed for adsorption of low molecular weight aromatic compounds by multi-walled carbon nanotubes (MWCNTs) using experimental data for 59 compounds. Quantitative structure-activity relationship (QSAR) and linear solvation energy relationship (LSER) approaches were employed and developed models were externally validated using an independent dataset obtained from the literature. Up to date, no QSAR model has been reported for predicting adsorption of organics by CNTs. No LSER model is available which comprehensively investigates the adsorption …

Biology, Ecology, And Control Of Doveweed (Murdannia Nudiflora [L.] Brenan), Jeffrey Atkinson

All Dissertations

Doveweed (Murdannia nudiflora [L.] Brenan) is a summer annual in the Southeastern United States with an expanding geographic range. The light green color and texture of doveweed is problematic for turfgrass managers as it contrasts with the color and texture of desirable turfgrasses. Limited research is available concerning the biology, ecology, and herbicide control options for doveweed. Therefore, experiments were conducted to improve the understanding of how environmental conditions effect doveweed germination, how cultural practices and environmental resource availability effect doveweed growth and development, to identify pre- and postemergence herbicides with efficacy for doveweed control, and to improve the understanding …

Passivation And Functionalization Of Conjugated Polymer Nanoparticles With Head Group Modified Phospholipids And Proteins, Prakash Kandel

All Dissertations

Conjugated polymer nanoparticles (CPNs) possess important characteristics such as high fluorescence brightness, reasonable photostability, and non-toxicity. These properties allow the use of CPNs in fluorescence based cellular and biological applications including cellular labeling, imaging, biosensing, and single particle tracking. To realize the broad applications of CPNs, it is required that CPNs possess functionality to conjugate a recognition moiety and maintain colloidal stability in biological media. In the following Dissertation, we have prepared functionalized CPNs by surface passivation with head group- functionalized poly (ethylene glycol) lipids and proteins. We studied the colloidal stability of CPNs in biological media and investigated their …

Evaluation Of A Mycorrhizal-Like Fungus, Piriformospora Indica, On Floriculture Crops, Allison Justice

All Dissertations

Piriformospora indica is a fungal endophyte, often called an arbuscular mycorrhizal-like fungus, that has been shown to provide benefits to plant symbionts by increasing nutrient uptake, biomass production, flower number, and disease resistance in a wide range of plant hosts. Research was carried out to investigate the ability of P. indica to improve plant production in floriculture crops. The first objective was to determine the optimal environmental conditions for growing P. indica in pure culture. Environmental conditions were optimized to produce the maximum chlamydospores for inoculum preparation (Chapter 1). These findings were used in the remaining chapters to prepare inocula …

Mechanisms And Reversal Of Elastin Specific Medial Arterial Calcification, Yang Lei

All Dissertations

There are two distinctive types of vascular calcification: atherosclerotic intimal calcification (AIC) and elastin specific medial arterial calcification (MAC). AIC occurs in the context of atherosclerosis, associated with lipids, macrophages, and vascular smooth muscle cells; whereas, MAC can exist independently of atherosclerosis and is associated with elastin and vascular smooth muscle cells. The work presented here focuses on the mechanisms and reversal of MAC. MAC, termed as Monckeberg's sclerosis, is a type of vascular calcification disease mostly occurs as linear deposits along elastic lamellae. Vascular calcification, including medial calcification, is a strong predictor of cardiovascular morbidity and mortality. Currently the …

All Dissertations

Sustainability concerns arising from over-use of fossil-derived materials have prompted renewed interest in developing and use of products from renewable biomass. Agricultural materials like soy, starches, cellulose esters and co-products like lignin, soybean meal, feather meal, blood meal and others are being investigated for bioplastic applications. Unlike fossil-based plastics, most of these materials are biodegradable and obtained from renewable precursors, hence sustainable.

Tides And Air, Kristine R. Synowka

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis discusses the intermedia and sculptural artwork for Kristine R. Synowka's exhibition, Tides and Air. Through a wide variety of different media, both traditional and electronic, a hypothetical world split between terrestrial plants and weeds and ocean environments is explored within the space of the gallery. Echoing the movement of the viewer through the gallery space, the imagery switches focus from the familiar backyard plants to an oceanic realm based off the kinds of environments that we mostly know from theory. A possible new mythology relating to animals is subtly hinted at through encounters with artwork portraying animals from …

Heterotrophic Culture Of Microalgae Using Biodiesel Derived Glycerol, Karthik Gopalakrishnan

All Dissertations

Algae-based technologies are fast growing and the growing demand for sustainable technologies is evident from the growing energy demand and global warming. Microalgae culturing for higher lipid contents have been a hot topic of intense discussion in the past years. Crude glycerol, a byproduct from biodiesel production seems to be an attractive feedstock for microbial cultivation and crude glycerol has been proven as a good alternative feedstock for cultivation of Chlorella protothecoides. The effect of impurities present in the crude glycerol is important to develop a method for high-density cultivation of microalgae to increase the commercialization potential of algae systems. …

Platform Technologies To Advance Clinically Relevant Tissue Engineered Heart Valve Products, Leslie Neil Sierad

All Dissertations

Diseased heart valves are commonly replaced by mechanical, bioprosthetic, or allograft heart valves. These replacements provide major improvements in cardiac function and quality of life, but have significant limitations and eventually require surgical replacement within 15-20 years. These risks are particularly prominent in pediatric patients and young adults. The field of tissue engineering and regenerative medicine, which combines scaffolds and cells, holds great promise in developing living replacement heart valves that would self-repair and grow in size along with the growing children.

The long-term goal of this project is to generate living, tissue-engineered heart valves from biological scaffolds and autologous …
