Influencing Factors On Plankton Populations In A Desert Man -Made Lake, Steven Weber Jan 2006

Influencing Factors On Plankton Populations In A Desert Man -Made Lake, Steven Weber

UNLV Retrospective Theses & Dissertations

The purpose of this study was to examine and identify the factors that have influenced changes in phytoplankton and zooplankton assemblages during the initial thirteen years of ecological development of Lake Las Vegas, Clark County, Nevada. Univariate and multivariate statistical methods were used to determine the level of influence lake water chemistry, lake physical characteristics and planktonic groups will have on overall plankton community dynamics. Water quality and plankton population data have been collected since 1991 when the lake began filling through the period of study ending December, 2003; Results indicate the zooplankton biomass was most influenced by conductance, total …


Removal Of The Cyanobacterial Toxin Microcystin -Lr By Biofiltration: Identification Of Toxin-Degrading Bacteria And Effects Of Backwashing, Lazaro Eleuterio Jan 2006

Removal Of The Cyanobacterial Toxin Microcystin -Lr By Biofiltration: Identification Of Toxin-Degrading Bacteria And Effects Of Backwashing, Lazaro Eleuterio

UNLV Retrospective Theses & Dissertations

The removal of the cyanobacterial toxin microcystin-LR by slow and rapid drinking water biofilters, the presence of the microcystin-degrading bacteria in operating biofilters, the impact of backwashing on the removal of microcystin by biofiltration, and the prediction of microcystin-LR removal using a nonsteady-state biofilm model were investigated. A newly recognized microcystin-LR degrader, Morganella morganii, exists in Lake Mead and operating active biofilters. The results of the biodegradation tests indicated that addition of a carbon source, in the form of biodegradable NOM, significantly delayed the degradation of microcystin-LR. The biofiltration experiments demonstrated that at steady-state, biofiltration may be a potential technology …


Vestiges Of Desegregation: Black Superintendent Reflections On The Complex Legacy Of Brown V Board Of Education, Sonya Douglass Horsford Jan 2006

Vestiges Of Desegregation: Black Superintendent Reflections On The Complex Legacy Of Brown V Board Of Education, Sonya Douglass Horsford

UNLV Retrospective Theses & Dissertations

Research reflecting the diverse thoughts, experiences, and perspectives of the Black school superintendent is scarce despite the noteworthy role Black leaders and educators have demonstrated within and beyond the Black community. Although there is extensive literature on the impacts of segregation, desegregation, and resegregation on Black student achievement and the promise and failures of school choice reform, my review of related literature revealed an absence of voices belonging to those individuals who possess the personal and professional experiences that may inform these very complex issues---Black school superintendents; This qualitative dissertation study documents and explores the reflections and perspectives of eight …

Isothermal Titration Calorimetry And Transmission Electron Microscopy Of Main-Chain Viologen Polymer Containing Bromide As Counerions, Pradip K. Bhowmik, Marcos A. Cheney, Haesook Han, Longzhou Ma

Transmission Electron Microscope

Polyelectrolytes are an important class of macromolecules that contain dissociable ionic groups. When introduced into polar solvent, usually the universal solvent water, dissociation takes place so that electrically charged macromolecule is suspended in solution. The electrostatic interaction is operative between ionized groups inside the macromolecule, between the macromolecules, between the counterions, and between the macromolecule and counterion. Since this interaction is characterized by its long-range nature, the solution exhibits various interesting properties including the polyelectrolyte behavior very different from solutions of neutral polymers.

The Use Of Β-Actin Mrna Degradation To Estimate Bloodstain Age, Kristin Nicole Nestor Jan 2006

The Use Of Β-Actin Mrna Degradation To Estimate Bloodstain Age, Kristin Nicole Nestor

Graduate Theses, Dissertations, and Problem Reports (ETD)

The time of deposition of biological samples at a crime scene is vital for interpreting the value of the samples in cases where the location by itself is not incriminating. Previous work from our laboratory showed a method to estimate the bloodstain age by using reverse transcription real-time PCR based on the amount of RNA decay of 18S compared to β-actin. In order to eliminate variability in expression levels between 18S and β-actin, an approach utilizing two differently sized regions of the β-actin gene was investigated. Results indicated ethnicity, age, and gender of the individual from whom the blood was …

The Effects Of Residual Trees On Regeneration Dynamics Following A Diameter Limit Harvest, Travis J. Deluca Jan 2006

The Effects Of Residual Trees On Regeneration Dynamics Following A Diameter Limit Harvest, Travis J. Deluca

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ten years after diameter-limit cutting, shading from residual trees had a negative effect on regeneration growth in three Appalachian hardwood stands. Regardless of shade tolerance, saplings growing outside the crown shading of residual overstory trees had higher densities and were taller and larger in diameter. Most shade-intolerant and mid-tolerant species decreased in total height and diameter as overstory basal area increased. Black cherry height (p<0.0001) and diameter (p=0.0002) had a significant negative relationship with increasing overstory basal area. Total height of shade-tolerant species was not affected and diameter showed a positive relationship. Red maple diameter had a significant positive relationship (p<0.0001) with increasing overstory basal area. Rehabilitation of stands after diameter-limit cutting requires silvicultural release operations to reduce competition in the new cohort.

Portable Transparent Indenter Instrumentation For Material Surface Characterization, Julio A. Noriega

Graduate Theses, Dissertations, and Problem Reports (ETD)

A portable Transparent Indenter Measurement (TIM) instrument that combines Instrumented Indentation Testing characteristics with optical microscopy through a transparent half ball indenter has been developed. The TIM instrument can provide the following experimental data: (a) the load applied as the indenter penetrates the specimen, (b) the displacement of the piezoelectric tip, and (c) the indented area. All these data are used to obtain the material stress-strain curve, through the determination of the elastic modulus, yield strength, and strain hardening exponent.;Using the TIM instrument and based on Hertz elastic contact theory, a new method to obtain material elastic modulus is developed. …


Tumor Necrosis Factor-Alpha Production Induced By Peptidoglycan-Polysaccharide In Early Pregnant Ewes, Gabrielle Marie Rogers Jan 2006

Tumor Necrosis Factor-Alpha Production Induced By Peptidoglycan-Polysaccharide In Early Pregnant Ewes, Gabrielle Marie Rogers

Graduate Theses, Dissertations, and Problem Reports (ETD)

Peptidoglycan-polysaccharide (PG-PS), cell wall component of gram-positive bacteria, was used to intoxicate sheep to study mastitis-related reproductive failure, mediated by TNF-alpha. Estrus was synchronized in ten adult Suffolk ewes. Four days after mating (Day 0) the jugular and posterior vena cava (saphenous vein) were catheterized. On Day 5, ewes were assigned randomly to either: control group (n = 4, 0.9% NaCl), or PG-PS group (n = 6, 30 mug/kg BW, i.v.). Plasma samples were collected from both jugular and saphenous vein catheters every 15 minutes for 6 hours. Radioimmunoassay quantified concentrations of TNF-alpha. Data were analyzed using repeated-measures analysis of …


Adolescent Religiosity And Conformity To Parents: Is Sex A Moderator?, Rebecca Kim Summers Jan 2006

Adolescent Religiosity And Conformity To Parents: Is Sex A Moderator?, Rebecca Kim Summers

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examines relations between adolescent reports of conformity to their parents and religiosity and if these are moderated by the sex of the adolescent and parent. Self-report data was collected from 121 ninth and tenth graders enrolled in three non-metropolitan high schools. Religiosity was measured by Schumm et al.'s (1991) modified version of Gorsuch and Venable's (1983) scales. Conformity to Parents was assessed using Peterson's (Peterson, Rollins, & Thomas, 1985) Conformity to Parents scales. Four regressions were used. Results indicate that females: (a) report higher levels of conformity to parents and religiosity than males and (b) that when adolescent …

Beyond The Binary: Rorty Rushdie, Zachary Mori Bonner Jan 2006

Beyond The Binary: Rorty Rushdie, Zachary Mori Bonner

Honors Theses

Salman Rushdie's Midnight's Children is a two-pronged postcolonial critique. Saleem Sinai's metanarrative of emancipation that also overhauls the postcolonial episteme.^ While Rushdie's confrontation of native subjectivity and the epistemic structures that inhibit the native's agency are plainly rooted in the postcolonial conversation, the major theorists in the field do not offer models of opposition that properly house his intervention. The work of Edward Said, Homi K. Bhabha, and Gayatri Spivak is representative of the trajectory of the strategies of discursive opposition to the employed by postcolonial theory. None of these theorists' metaphors for opposition create sufficient distance from the knowledge …


But I Didn't Do Anything Wrong: Revisiting The Rights Of Non-Offending Parents In Child Protection Proceedings, Vivek Sankaran Jan 2006

But I Didn't Do Anything Wrong: Revisiting The Rights Of Non-Offending Parents In Child Protection Proceedings, Vivek Sankaran

Articles

Steven, a minor living with his mother, enjoyed a nurturing relationship with his father, Mark. He saw his father every weekend and looked forward to their time together. Mark looked for ways in which to stay involved in his child's life. Two days ago, the Department of Human Services (DHS) removed Steven from his mother's custody because, unbeknown to Mark, Stevens mother was selling drugs in the home. At the time of removal, the police did not inquire about the whereabouts of Stevens father; DHS immediately placed Steven in a foster home.
