We present an investigation of the globular cluster (GC) systems of NGC 3607 and NGC 3608 as part of the ongoing SLUGGS (SAGES Legacy Unifying Globulars and GalaxieS) survey. We use wide-field imaging data from the Subaru telescope in the g, r and i filters to analyse the radial density, colour and azimuthal distributions of both GC systems. With the complementary kinematic data obtained from the Keck II telescope, we measure the radial velocities of a total of 81 GCs. Our results show that the GC systems of NGC 3607 and NGC 3608 have a detectable spatial extent of ∼15 …

E56h + E59h Mutation Affects Binding Of The Recombinant Haemphilus Influenza Carbonic Anhydrase To A Ni-Nta Column, Eric D. Lebel, Kathleen Cornely May 2016

E56h + E59h Mutation Affects Binding Of The Recombinant Haemphilus Influenza Carbonic Anhydrase To A Ni-Nta Column, Eric D. Lebel, Kathleen Cornely

Chemistry & Biochemistry Student Scholarship

The Haemophilus influenzae carbonic anhy- drase (HICA) is important in converting carbon dioxide to bicarbonate in bacteria. Endogenous cellular proteins, like Escherichia coli carbonic anhydrase (ECCA), have been observed to bind to a Ni-NTA column, which can be used as a means of protein purification. The possibility ex- ists that proteins that do not normally bind to Ni-NTA, like HICA, can be engineered using site directed mutagenesis to introduce histidine resi- dues that would give the protein the capability to bind, allowing for a one-step purification method. Site-directed mutagenesis was used to introduce the double mutation of E56H + E59H …

The Hopf Fibration And Encoding Torus Knots In Light Fields, John Vincent Waite May 2016

The Hopf Fibration And Encoding Torus Knots In Light Fields, John Vincent Waite

UNLV Theses, Dissertations, Professional Papers, and Capstones

The first sections of this thesis explore a construction of electromagnetic fields first proposed by Bateman and recently rediscovered and expanded upon. With this powerful and elegant tool, I show that it is possible to construct families of EM fields that have a common topological structure that is preserved throughout time. This topological structure, known as the Hopf fibration, has been found to manifest itself in many areas of physics. Due to its utility, I have made a detailed study of it. The final section of this thesis develops an algorithm to parameterize a closed, bounded, and oriented surface that …

Reactive oxygen species (ROS) have been implicated in tumorigenesis (tumor initiation, tumor progression, and metastasis). Of the many cellular sources of ROS generation, the mitochondria and the NADPH oxidase family of enzymes are possibly the most prevalent intracellular sources. In this article, we discuss the methodologies to detect mitochondria-derived superoxide and hydrogen peroxide using conventional probes as well as newly developed assays and probes, and the necessity of characterizing the diagnostic marker products with HPLC and LC-MS in order to rigorously identify the oxidizing species. The redox signaling roles of mitochondrial ROS, mitochondrial thiolperoxidases, and transcription factors in response to …

Nitrogen And Phosphorus Enrichment Effects On Nutrient Supply In Reservoirs: A Small-Scale Approach, Jessalyn G. Kohn

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Eutrophication is a problem in many lakes, but the reduction of nutrient inputs such as nitrogen (N) and phosphorus (P) to combat eutrophication can lead to an oligotrophic state, which may be unable to support healthy aquatic ecosystems. This study examined how different rates of chemical fertilization with N and P during times of nutrient limitation (mid-summer) could affect particulate N and C concentrations in four lakes in northwest Arkansas. Fertilization experiments were conducted in microcosms during the month of July 2014. Water samples from each lake were collected and divided into six treatments: control, P-only, N:P 10, 20, 40, …

⁸⁷Sr/⁸⁶Sr As A Potential Fingerprint For Determining The Provenance Of Total Dissolved Solids Associated With Hydraulic Fracturing Activities In The Barnett Shale, Texas, Richard Brian Goldberg

Earth & Environmental Sciences Theses - Archive

Over the last decade there has been a dramatic increase in unconventional drilling that utilizes hydraulic fracturing to extract oil and gas. The Barnett Shale in north central Texas has been a significant contributor to this increase in unconventional production. Potential environmental contamination from hydraulic fracturing and associated activities is a topic of current debate. One concern is the management of produced/flowback water (PFW), which contains high amounts of total dissolved solids (TDS) acquired from interaction with the reservoir formation and its constituents. Development and testing of geochemical methods to determine if a particular contaminant is the result of PFW …

Role For Reactive Oxygen Species In Methamphetamine Modulation Of Dopamine Release In The Striatum, David Matthew Hedges May 2016

Role For Reactive Oxygen Species In Methamphetamine Modulation Of Dopamine Release In The Striatum, David Matthew Hedges

Theses and Dissertations

Methamphetamine (METH) is a highly addictive substance that is highly prevalent in today’s society, with over 1 in 20 adults over 26 having taken it at least once. While it is known that METH, a common psychostimulant, acts on both the mesolimbic dopamine (DA) and nigrostriatal DA systems by affecting proteins involved in DA reuptake and vesicular packaging, the specific mechanism of what is known as METH neurotoxicity remains obscure, but has been shown to involve oxidative stress. Studies have shown that reactive oxygen species act on the same proteins that METH affects. Oxidative species have also been known to …

Generalized Linear Model Analyses For Treatment Group Equality When Data Are Non-Normal, Harvey J. Kesleman, Abdul R. Othman, Rand R. Wilcox May 2016

Generalized Linear Model Analyses For Treatment Group Equality When Data Are Non-Normal, Harvey J. Kesleman, Abdul R. Othman, Rand R. Wilcox

Journal of Modern Applied Statistical Methods

One of the validity conditions of classical test statistics (e.g., Student’s t-test, the ANOVA and MANOVA F-tests) is that data be normally distributed in the populations. When this and/or other derivational assumptions do not hold the classical test statistic can be prone to too many Type I errors (i.e., falsely rejecting too often) and/or have low power (i.e., failing to reject when the null hypothesis is false) to detect treatment effects when they are present. However, alternative procedures are available for assessing equality of treatment group effects when data are non-normal. For example, researchers can use robust estimators …

Liu-Type Logistic Estimators With Optimal Shrinkage Parameter, Yasin Asar

Journal of Modern Applied Statistical Methods

Multicollinearity in logistic regression affects the variance of the maximum likelihood estimator negatively. In this study, Liu-type estimators are used to reduce the variance and overcome the multicollinearity by applying some existing ridge regression estimators to the case of logistic regression model. A Monte Carlo simulation is given to evaluate the performances of these estimators when the optimal shrinkage parameter is used in the Liu-type estimators, along with an application of real case data.

The Xgamma Distribution: Statistical Properties And Application, Subhradev Sen, Sudhansu S. Maiti, N. Chandra

Journal of Modern Applied Statistical Methods

A new probability distribution, the xgamma distribution, is proposed and studied. The distribution is generated as a special finite mixture of exponential and gamma distributions and hence the name proposed. Various mathematical, structural, and survival properties of the xgamma distribution are derived, and it is found that in many cases the xgamma has more flexibility than the exponential distribution. To evaluate the comparative behavior, stochastic ordering of the distribution is studied. To estimate the model parameter, the method of moment and the method of maximum likelihood estimation are proposed. A simulation algorithm to generate random samples from the xgamma distribution …
