Occurrence And Proliferation Of Antibiotics And Antibiotic Resistance In Wastewater Treatment Plants, Majid Neyestani

UNLV Theses, Dissertations, Professional Papers, and Capstones

Solids retention time (SRT) is one of the most important factors in designing and operating activated sludge systems for biological wastewater treatment. Longer SRTs have been shown to alter the structure and function of microbial communities, thereby leading to improved treatment efficacy with respect to bulk and trace organics, nutrient removal, and membrane fouling. However, research has also shown that longer SRTs lead to increased prevalence of antibiotic resistant bacteria, perhaps due to increased exposure to antibiotics present in influent wastewater. The purpose of this study was to characterize changes in microbial community structure in a laboratory-scale activated sludge system …

The Effects Of Cryopreservation On Human Dental Pulp-Derived Mesenchymal Stem Cells, Allison Elaine Tomlin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many studies have demonstrated clinical applications for the use of dental pulp stem cells (DPSC) for the treatment of various conditions. This has driven medical and scientific interest in the collection, isolation and banking of DPSC tissues for research into these potential therapies. Few studies to date have evaluated the viability of DPSC following long-term cryopreservation. The purpose of this study is to evaluate the effects of cryopreservation on dental pulp-derived stem cells (DPSC) viability over a period of three years. Dental pulp-derived stem cells were isolated and cultured from thirty-one healthy teeth. DPSC isolates were assessed for doubling-time and …

Enhancing The Draft Assembly With Minhash, Saju Varghese

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this thesis, we report on the use of minhash techniques to improve the draft assembly of a genome mapping. More specifically, we use minhash to compare the scaffolds of sea urchin and sea cucumber genomes.

One of the main contributions of this thesis is the implementation of minhash with the Message Passing Interface (MPI) utilizing Intel Phi co-processors. It is shown that our implementation significantly reduces the processing time for identification of k-mer similarities.

Behavioral Reactions To Emotional And Physical Infidelity: An Evolutionary Perspective, Mandy Walsh Walsh

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis examined the effects of sex and type of partner infidelity, including both physical (i.e., sexually involved with another person) and emotional (i.e., emotionally involved with another person) infidelity, on mate abandonment behaviors. Previous research has demonstrated sex differences in emotional responses to infidelity, where men react more negatively to physical infidelity and women react more negatively to emotional infidelity. While various studies have investigated perceived behavioral reactions using imagined scenarios, this study expands current research by utilizing actual retrospective reports. It was hypothesized that males would engage in significantly more mate abandonment behaviors after experiencing a physical infidelity, …

Statistical Inference Of Genetic Forces Using A Poisson Random Field Model With Non-Constant Population Size, Jianbo Xu

UNLV Theses, Dissertations, Professional Papers, and Capstones

The fidelity of DNA sequence data makes it a perfect platform for quantitatively analyzing and interpreting evolutionary progress. By comparing the information between intraspecific polymorphism with interspecific divergence in two sibling species, the well established Poisson Random Field theory offers a statistical framework with which various genetic parameters such as natural selection intensity, mutation rate and speciation time can be effectively estimated. A recently developed time-inhomogeneous PRF model has reinforced the original method by removing the assumption of stationary site frequency, but it preserves the condition that the two sibling species share same effective population size with their ancestral species. …

Beal, Michael J. Walsh, Robert R. Bidigare, Susan L. Brown, William P. Cochlan, Zackary I. Johnson, Xin Gen Lei, Stephen C. Machesky, Donald Redalje, Ruth E. Richardson, Viswanath Kiron, Virginia Corless

Faculty Publications

Climate, energy, and food security are three of the greatest challenges society faces this century. Solutions for mitigating the effects of climate change often conflict with solutions for ensuring society’s future energy and food requirements. For example, BioEnergy with Carbon Capture and Storage (BECCS) has been proposed as an important method for achieving negative CO2 emissions later this century while simultaneously producing renewable energy on a global scale. However, BECCS has many negative environmental consequences for land, nutrient, and water use as well as biodiversity and food production. In contrast, large-scale industrial cultivation of marine microalgae can provide society with …

Evaluating The Suitability Of Microbial Induced Calcite Precipitation Technique For Stabilizing Expansive Soils, Sikha Neupane

Boise State University Theses and Dissertations

Expansive soils, also known as swell-shrink soils have been a problem for civil infrastructures including roads and foundations from ancient times. The use of chemical additives such as cement and lime to stabilize expansive soils is a common practice among geotechnical engineers especially for lightly loaded structures. However, several occurrences of subgrade failures were observed after stabilizing with chemical additives hence engineers are in search of sustainable stabilization alternatives. Microbial Induced Calcite Precipitation (MICP) is gaining attention as an environmental friendly soil improvement technique. Several researchers have successfully tested its feasibility in mitigating liquefaction induced problems in sandy soils. This …

To Boldly Go: Boldness Predicts Behavior And Survivorship Of A Critical Prey Species, Zoe Katherine Tinkle

Boise State University Theses and Dissertations

Understanding population dynamics is at the core of conservation biology. However, our understanding of the mechanisms driving population dynamics remains unclear in many cases. Animal behavior in response to biotic and abiotic stressors is an important driver of these population dynamics and varies both within- and among-individuals in a population. Consistent differences in behavior among individuals within a population are referred to as personality traits. Boldness, a personality trait representing the willingness of an individual to engage in risky behavior, may help predict individual and community-level consequences, such as survivorship. Here, we investigated the inter- and intra-individual variation in risk-taking …

Barn Owls (Tyto Alba) Crossing The Road - Examining The Interplay Among Occupancy, Behavior, Habitat Selection, And Roadway Mortality In Southern Idaho, Tempe Regan

Boise State University Theses and Dissertations

Barn Owls (Tyto alba) are killed by vehicle collisions in greater numbers than any other North American bird of prey. Interstate-84 (I-84) in southern Idaho, USA has among the world’s highest known rates of Barn Owl-vehicle collisions. Little is known about Barn Owl occupancy in this region, so it is unclear if owls are killed in proportion to their abundance, or if they are equally abundant in segments with lower mortality and somehow escape collisions. Furthermore, studies of Barn Owl movements and behavior are limited. I was interested in understanding (1) factors that affect Barn Owl occupancy in …

Focus Structures In Copala Triqui, Zena Zimmerglass

Linguistics

The purpose of this research is to identify the techniques used by speakers of Copala Triqui to focus one or more constituents in a sentence. Copala Triqui is a native Mexican language originating in the region that is now San Juan Copala, Mexico. In this experiment, we tested for five types of focus: broad focus, subject focus, object focus, contrastive subject focus, and contrastive object focus. We captured these patterns by having speakers answer Triqui questions that elicited the appropriate type of focus. We found that some focused sentences allow for deviations in word order from non-focused or broad-focused ones. …

Will Consumers Be In The "Dark" About Labels On Genetically Engineered And Modified Foods?, Hilary Nat

Journal of Food Law & Policy

In the 1900s, the United States began to sell genetically engineered foods. One of the first genetically engineered foods sold in the United States and approved by the Food and Drug Administration (FDA) was the Flavr Savr tomato. The tomato's genetic structure was modified to prevent softening which allowed it to ripen after being picked. In the United States, statistics demonstrate that 92% of com, 94% of soybeans, and 94% of cotton sold is genetically engineered. In addition, it is estimated that 75% of the processed foods sold in supermarkets around the United States contain ingredients that are products of …

Criminal Law, Bernadette C. Crucilla

Mercer Law Review

As in prior periods, this year's survey of criminal law will include only a few of the most significant cases and statutory amendments. Due to the constant evolution of criminal laws in our society, it is simply not practical to attempt to make note of every legal development. Therefore, the discussion is limited to those changes that will have the widest application and interest to criminal law practitioners for the period from June 1, 2015 through May 31, 2016.

Chlorpyrifos Removal For Wastewater Reuse, Indran Kamalanathan

Chemical Engineering Undergraduate Honors Theses

Approximately 1.2 billion people around the world live in areas of physical water scarcity. This could increase to half of the world’s population by 2030 and could displace 24 to 700 million people unless steps are taken to ensure adequate water supply.¹ Water scarcity is an escalating issue within the United States, specifically in Western inland states with arid climates. This scarcity is encouraging communities to investigate tertiary level municipal wastewater treatment, allowing for reuse of wastewater. Unfortunately, wastewater contains numerous contaminants that are not regulated by the Environmental Protection Agency (EPA) under the Safe Drinking Water Act (SDWA). …

Race And Criminal Justice In Canada, Charles E. Reasons, Shereen Hassan, Melinda Bige, Christianne Paras, Simranjit Arora

All Faculty Scholarship for the College of the Sciences

The relationship between race and crime has long been a subject of study in the United States; however, such analysis is more recent in Canada. A major factor impeding such study is the fact that racial/ethnic data are not routinely collected and available in Canada, unlike the United States. The collection of such data would arguably undermine the multi-cultural mosaic of Canada as a place of acceptance and tolerance. However, the lack of such data bellies research suggesting that race plays a role in the Canadian criminal justice system. Using available, albeit, limited research studies and their data, the role …

M049 Effects Of Compaction And Soil Moisture On American Burying Beetles, W. Wyatt Hoback

Nebraska Department of Transportation: Research Reports

Silphid beetles in the genus Nicrophorus bury themselves during periods of inactivity, however, the influence of soil characteristics on burial behavior remains unclear. We examined soil preferences of the federally endangered Nicrophorus americanus, as well as of N. carolinus, N. marginatus, N. obscurus, and N. orbicollis, in a series of experiments. Differences in burial depth by sex were found for N. carolinus, N. marginatus, and N. obscurus, which are diurnal species. Both sexes of N. americanus bury to a mean depth of 18 cm. Soil preferences tested included sand versus sandy loam versus sandy loess, degrees of soil moisture, and …

Efficacy Of Intravenous Ondansetron In Relieving Nausea/Vomiting And Pruritus Post Epidural Administered Opioids In The Obstetric Patient, Benjamin Stephen Butler

Doctoral Projects

One prominent side effect in the use of a neuraxial anesthesia is pruritus, with an incidence in the obstetric patient of 60-100% (Kumar & Singh, 2013). Another side effect of an epidural placement is nausea and vomiting. Nausea and vomiting occurs frequently during the progress of labor and is difficult to determine an incidence that is related to epidural opioid administration (Chestnut, Wong, Tsen, Ngan Kee, Beilin, & Mhyre, 2014). A review of literature was performed and established evidence that ondansetron is effective in reducing incidence of pruritus in intrathecal administered opioids for cesarean sections in the obstetric patient. No …

Opioid Use In The Cesarean Section Patient With The Preoperative Administration Of Intravenous Acetaminophen, Dana Edwards Bernardo

Doctoral Projects

Cesarean sections are one of the most common surgical procedures and there are no current guidelines for the management of postoperative pain control (Darvish, Ardestani, Shali, & Tajik, 2013). Unresolved pain in this population can lead to long lasting problems, such as chronic pain and depression (Booth, Harris, Eisenach, & Pan, 2015). The goal of multimodal therapy with IV acetaminophen for CS mothers was to ensure a rapid and safe recovery process with reduced adverse complications and shortened hospital length of stay. The independent t-test was used to compare the mean time for length of stay, first request of pain …

Spiritual Direction With Children The Next Natural Step In The Christian Historical Progression Of Children's Spiritual Formation, Lacy Finn Borgo

Doctor of Ministry

Children without a listening and guiding companion miss opportunities to build upon their connection with God and others. Historically, from a western Protestant viewpoint, Christians have struggled to understand or acknowledge, much less encourage, the reciprocal nature of a child’s life with God. Supporting the reciprocal nature of a child’s life with God includes acknowledging their full humanity by embracing childhood as a fully human state and therefore their need for a whole person spiritual formation. The institution of Sunday School, Godly Play, and the Children’s Spirituality Movement have each helped us to understand, acknowledge and encourage a child’s life …

Roles Of Nucleolin: Focus On Cancer And Anti-Cancer Therapy, Zhuo Chen, Xinhua Xu

Saudi Medical Journal

Nucleolin, a multifunctional protein distributed in the nucleolus, participates in many modulations including rDNA transcription, RNA metabolism, and ribosome assembly. Nucleolin is also found in the cytoplasm and on the cell membrane, and surface nucleolin can bind to various ligands to affect many physiological functions. The expression and localization of nucleolin is often abnormal in cancers, as the differential distribution of nucleolin in cancer can influence the carcinogenesis, proliferation, survival, and metastasis of cancer cells, leading to the cancer progression. Thus, nucleolin may be a novel and promising target for anti-cancer treatment. Here, we describe how nucleolin act functions in …

A New System For Human Microrna Functional Evaluation And Network, Jiachun Han

School of Computing: Dissertations, Theses, and Student Research

MicroRNAs are functionally important endogenous non-coding RNAs that silence host genes in animal and plant via destabilizing the mRNAs or preventing the translation. Given the far-reaching implication of microRNA regulation in human health, novel bioinformatics tools are desired to facilitate the mechanistic understanding of microRNA mediated gene regulation, their roles in biological processes, and the functional relevance among microRNAs. However, most state-of-the-art computational methods still focus on the functional study of microRNA targets and there is no e ective strategy to infer the functional similarity among microRNAs. In this study, we developed a new method to quantitatively measure the functional …

Determination Of Plant Architecture And Component Phenotyping Based On Time-Lapse Image Analysis, Srinidhi Bashyam

School of Computing: Dissertations, Theses, and Student Research

Plant breeding and the development of new food production depend on accurate measurement of different phenotypes (observable physical traits) of a plant. The plant phenotypes play a very important role in the agronomic production. The successful computation of plant phenotypes largely depends on the determination of the architecture of the plant, i.e., the arrangement of its parts (leaves, stems, flowers, etc.) relative to each other, and how the size, shape, and positions of those parts change over time. Researchers and breeders extract valuable information from these types of data to make an informed decision on which individuals to advance to …

Simulation Of Aircraft Sortie Generation Under An Autonomic Logistics System, Gunduz Bingol

Theses and Dissertations

Parallel to the developments in diagnostic and prognostic technology, autonomic logistics systems (ALS) have been a potential improvement for the aircraft sortie generation process. Currently, Lockheed Martin and the Joint Program Office are developing a new autonomic logistics system for the multibillion F-35 Lightning Joint Strike Fighter project, which is named the Autonomic Logistics Information System (ALIS). Generally, researchers make an analogy between the ALS and the human bodys autonomic nervous system since both of them monitor, control, and adjust autonomic responses to external stimuli. Based on this perspective, ALS aims to switch the Air Force logistics mentality from a …

Nicotinamide Adenine Dinucleotide Phosphate Oxidase 2 Regulates Lps-Induced Inflammation And Alveolar Remodeling In The Developing Lung., Heather Menden, Sheng Xia, Sherry M. Mabry, Angels Navarro, Michael F. Nyp, Venkatesh Sampath

Manuscripts, Articles, Book Chapters and Other Papers

In premature infants, sepsis is associated with alveolar simplification manifesting as bronchopulmonary dysplasia. The redox-dependent mechanisms underlying sepsis-induced inflammation and alveolar remodeling in the immature lung remain unclear. We developed a neonatal mouse model of sepsis-induced lung injury to investigate whether nicotinamide adenine dinucleotide phosphate oxidase 2 (NOX2) regulates Toll-like receptor (TLR)-mediated inflammation and alveolar remodeling.

Interpreting Measurements Of Cardiac Function Using Vendor-Independent Speckle Tracking Echocardiography In Children: A Prospective, Blinded Comparison With Catheter-Derived Measurements., Suma Goudar, G Hamilton Baker, Shahryar M. Chowdhury, Kimberly J. Reid, Girish S. Shirali, Mark A. Scheurer

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Adult studies demonstrate that echocardiographic measurements of cardiac function using speckle tracking correlate with invasive measurements, but such data in the pediatric population are sparse. Our aim was to compare speckle-derived measures of cardiac function to measurements routinely obtained by cardiac catheterization in children.

METHODS: Echocardiograms were performed on the day of cardiac catheterization. Using Tomtec 2D Cardiac Performance Analysis, longitudinal strain (LS), longitudinal strain rate (LSR), early diastolic LSR, and ejection fraction (EF) for the right and left ventricle (RV and LV) were calculated via speckle tracking. Global LS and LSR were calculated for the LV. These results …
