Investigations Into The Application Of Single-Beam Acoustic Backscatter For Describing Shallow Water Marine Habitats, Greg Foster 2010 Nova Southeastern University

Investigations Into The Application Of Single-Beam Acoustic Backscatter For Describing Shallow Water Marine Habitats, Greg Foster

HCNSO Student Theses and Dissertations

Chapter 1

Producing thematic coral reef benthic habitat maps from single-beam acoustic backscatter has been hindered by uncertainties in interpreting the acoustic energy parameters E1 (~roughness) and E2 (~hardness), typically limiting such maps to sediment classification schemes. In this study acoustic interpretation was guided by high-resolution LIDAR (Light Detection And Ranging) bathymetry. Each acoustic record, acquired from a BioSonics DT-X echosounder and multiplexed 38 and 418 kHz transducers, was paired with a spatially-coincident value of a LIDAR-derived proxy for topographic complexity (Reef-Volume) and its membership to one of eight LIDAR-delineated benthic habitat classes. The discriminatory capabilities of the 38 and ...

Impact Of Resistance Training On Balance And Gait In Multiple Sclerosis, Mary Filipi, M. Patricia Leuschen, Jessie M. Huisinga, Lorene Schmaderer, Jeanna Vogel, Daryl Kucera, Nicholas Stergiou

Journal Articles

Multiple sclerosis (MS) is an incurable neurodegenerative disease whose symptoms are only partially relieved by pharmaceutical intervention. Disability due to this disease process can impede activities of daily living and decrease quality of life, both for MS patients and for their care partners and families. A nonrandomized, nonblinded prospective cohort study of 45 patients with MS was undertaken to investigate the impact of an exercise program emphasizing resistance training on balance and gait. This article presents data for the first 33 participants to complete the study protocol. The exercise program consisted of twice-weekly 50-minute sessions for 6 months. At 3 ...

Rapid Biocompatibility Analysis Of Materials Via In Vivo Fluorescence Imaging Of Mouse Models, Kaitlin M. Bratlie, Tram T. Dang, Stephen Lyle, Matthias Nahrendorf, Ralph Weissleder, Robert Langer, Daniel G. Anderson

Kaitlin M. Bratlie

Background: Many materials are unsuitable for medical use because of poor biocompatibility. Recently, advances in the high throughput synthesis of biomaterials has significantly increased the number of potential biomaterials, however current biocompatibility analysis methods are slow and require histological analysis. Methodology/Principal Findings: Here we develop rapid, non-invasive methods for in vivo quantification of the inflammatory response to implanted biomaterials. Materials were placed subcutaneously in an array format and monitored for host responses as per ISO 10993-6: 2001. Host cell activity in response to these materials was imaged kinetically, in vivo using fluorescent whole animal imaging. Data captured using whole ...

Cellulosic Ethanol: The Benifits, Obstacles, And Implications For Nebraska, Cassidee Lin Thompson 2010 University of Nebraska at Lincoln

Cellulosic Ethanol: The Benifits, Obstacles, And Implications For Nebraska, Cassidee Lin Thompson

Environmental Studies Undergraduate Student Theses

Abstract Ethanol is a biofuel that has unique capabilities to mitigate global climate change by reducing greenhouse gas emissions while simultaneously supporting rural economies and decreasing the United States’ dependence on foreign oil. Currently, the state of Nebraska depends on corn ethanol, which may be unsustainable. Cellulosic ethanol is a promising alternative but it is not without its problems, including high production costs and potential environmental damage. This thesis is an attempt to understand the benefits, downfalls, and processes of corn-based and cellulosic ethanol and the potential implications to Nebraska. This research should shed some light on the current obstacles ...

Effect Of Membrane Cholesterol Levels And Allelic Variation On Prion Conversion, Ross Hartman 2010 Carroll College, Helena, MT

Effect Of Membrane Cholesterol Levels And Allelic Variation On Prion Conversion, Ross Hartman

Life and Environmental Sciences Undergraduate Theses

Chronic Wasting Disease (CWD) is caused by an accumulation of misfolded prion proteins (PrPsc) and subsequent plaque formation in the central nervous system. CWD is horizontally transferable; misfolded prions from one animal can enter another and cause normal prion proteins (PrPc) to misfold. This misfolding process is termed prion conversion. In natural deer populations an allelic variation in the prion gene is thought to confer resistance to CWD. Wild type mule deer are serine (S) homozygotes at codon 225. Mule deer that are Serine/ Phenyalanine (S/F) heterozygotes exhibit resistance to prion infection. In this study the F encoding allele ...


The Reaction Of A Water Soluble Platinum Compound With Methionine And Derivatives, Yueh Ying Liao 2010 Western Kentucky University

The Reaction Of A Water Soluble Platinum Compound With Methionine And Derivatives, Yueh Ying Liao

Masters Theses & Specialist Projects

Water soluble platinum complexes are a recent area of emphasis of cisplatin chemistry. The water soluble complexes could have a reduced toxicity compared with cisplatin. Oxaliplatin, which has an oxalate leaving group, has previously been shown to have less nephro-toxicity and higher water solubility than cisplatin. [Pt(en)(oxalate)] (en = ethylenediamine) has been prepared from Pt(en)Cl2 and silver oxalate. This complex has been reacted with methionine and N-acetylmethionine at different molar ratios. At high Pt: methionine ratios, chelates with the sulfur and nitrogen atoms of the methionine are dominant; at lower Pt: methionine ratios, a bis-methionine product is ...


Detection Of West Nile Virus In Mosquitoes Of Montana Through Rt-Pcr And Taqman Assays And Correlation To Reservoir Competent Avian Populations, Katie Semmens 2010 Carroll College, Helena, MT

Detection Of West Nile Virus In Mosquitoes Of Montana Through Rt-Pcr And Taqman Assays And Correlation To Reservoir Competent Avian Populations, Katie Semmens

Life and Environmental Sciences Undergraduate Theses

First emerging in the United States in 1999, and Montana in 2002, West Nile Virus (WNV) has had a significant impact on human and avian populations. Due to this significance, a greater understanding of the factors affecting the prevalence of WNV is necessary. Mosquitoes were collected from 27 locations across the state of Montana throughout the summer of 2009. RT-PCR and TaqMan assays were used to identify positive pools of mosquitoes, with three locations testing positive. As avian species serve as a reservoir for the virus, it is hypothesized that locations testing positive for WNV should have a greater presence ...


Speciation In The Simulium Arcticum Species Complex In The Pacific Northwest, Michael Kratochvil 2010 Carroll College, Helena, MT

Speciation In The Simulium Arcticum Species Complex In The Pacific Northwest, Michael Kratochvil

Life and Environmental Sciences Undergraduate Theses

Sequences of the mitochondrial genes, cytochrome oxidase 1 and II {COI and COII) were used to estimate the phylogenic relationships of five siblings and eight cytotypes of the Simulium arcticum complex from cytogenetically identified larvae. These 13 taxa are all differentiated by unique Y chromosome inversions, and in the present study a phylogeny based on chromosome types was tested molecularly. Bayesian analysis showed that taxa are non-monophyletic, in that sequences of different taxa are more closely related than are those of the same taxon. I conclude that incomplete lineage sorting as well as interspecific gene flow may explain these findings ...


Characterization And Normalization Of Rat Salivary Cholinesterase, Elise Klohe 2010 Carroll College, Helena, MT

Characterization And Normalization Of Rat Salivary Cholinesterase, Elise Klohe

Life and Environmental Sciences Undergraduate Theses

Cholinesterase (ChE) is an enzyme which allows neurons to return to a resting state by hydrolyzing the neurotransmitter acetylcholine. Organophosphate pesticides, which are commonly used in agriculture, inhibit the activity of ChE. The inhibition of ChE activity in plasma and red blood cells is used as a biomarker for human pesticide exposure. Currently, salivary ChE activity is being examined as a non-invasive biomarker; however little is known about baseline ChE activity in saliva. In order to characterize baseline salivary ChE, saliva was collected from 5 adult male SpragueDawley rats, salivary ChE was measured using the Ellman assay, and total salivary ...


Characterization Of Glycation Sites On Human Serum Albumin Using Mass Spectrometry, Omar S. Barnaby 2010 University of Nebraska-Lincoln

Characterization Of Glycation Sites On Human Serum Albumin Using Mass Spectrometry, Omar S. Barnaby

Student Research Projects, Dissertations, and Theses - Chemistry Department

The modification of proteins by reducing sugars is a process that occurs naturally in the body. This process, which is known as glycation, has been linked to many of the chronic complications encountered during diabetes. Glycation has also been linked to changes in the binding of human serum albumin (HSA) to several drugs and small solutes in the body. While these effects are known, there is little information that explains why these changes in binding occur. The goal of this project was to obtain qualitative and quantitative information about glycation that occurs on HSA. The first section of this dissertation ...


The Green Revolution Of The 1960'S And Its Impact On Small Farmers In India, Kathryn Sebby 2010 University of Nebraska at Lincoln

The Green Revolution Of The 1960'S And Its Impact On Small Farmers In India, Kathryn Sebby

Environmental Studies Undergraduate Student Theses

The Green Revolution was initiated in the 1960’s to address the issue of malnutrition in the developing world. The technology of the Green Revolution involved bio-engineered seeds that worked in conjunction with chemical fertilizers and heavy irrigation to increase crop yields. The technology was readily adopted in many stated in India and for some was a great success. However, there were many farmers who could not afford the inputs necessary to participate in the Green Revolution and gaps between social classes widened as wealthy farmers got wealthier and poor farmers lagged behind. This paper discusses how small farmers were ...

Minimun Riparian Buffer Width For Maintaining Water Quality And Habitat Along Stevens Creek, Sammi Bray

Environmental Studies Undergraduate Student Theses

ABSTRACT Riparian buffer zones are important sites of biodiversity, sediment trapping, pollutant removal, and hydrologic regulation that have significant implications for both people and wildlife. Urbanization’s influence on and need for adequate water quality increases the need for careful planning in regards to riparian areas. Wildlife are key components in the ecosystem functions of riparian zones and require consideration in peri-urban planning as well. This study reviews relevant literature to determine the recommended minimum riparian buffer width for maintaining water quality and habitat along Stevens Creek in Lincoln, Nebraska. Only sources that listed a specific purpose related to water ...


The Effects Of Ornamentation On Wolf Spider Foraging, Mari Pesek 2010 University of Nebraska at Lincoln

The Effects Of Ornamentation On Wolf Spider Foraging, Mari Pesek

Environmental Studies Undergraduate Student Theses

ABSTRACT: As a secondary sexual trait that can increase reproductive success, ornamentation is believed to be costly for organisms to acquire and possess. This study investigates possible costs of ornamentation on wolf spider foraging by comparing foraging abilities of two male forms that differ in ornamentation upon maturation. The two male forms, found syntopically in a mixed population in Mississippi, USA, resemble two sibling species: Schizocosa ocreata, in which males develop large black brushes on their forelegs upon maturation, and Schizocosa rovneri, in which males lack ornamentation following maturation. Individuals of both forms participated in foraging trials as penultimates (juveniles ...


A Potential Plan Of Action For Emerald Ash Borer In Nebraska, Lee Wheeler 2010 University of Nebraska at Lincoln

A Potential Plan Of Action For Emerald Ash Borer In Nebraska, Lee Wheeler

Environmental Studies Undergraduate Student Theses

Abstract Emerald Ash Borer (Agrilus planipennis) (EAB) is an invasive insect pest. It feeds on the cambium tissues of ash tree species. It was first discovered in the United States in 2002 in Detroit, Michigan. Their effects on ash trees are deadly, and it is quickly spreading across the Midwest. Nebraska has not yet been invaded, but confirmed findings continue getting closer and closer. The major problem facing Nebraskans, with regards to EAB, is how to begin preparations to prevent a dramatic economic loss when an infestation does occur. So, to address this problem, I have conducted street and park ...


Relatin Dissolved Oxygen Concentration To Fish Distribution In Jarecki Lake, Adam Sutton 2010 University of Nebraska at Lincoln

Relatin Dissolved Oxygen Concentration To Fish Distribution In Jarecki Lake, Adam Sutton

Environmental Studies Undergraduate Student Theses

Abstract Water temperature and dissolved oxygen (DO) profiles were measured once every month from mid July to mid February in a relatively deep sand-pit lake in southeast Nebraska. These profiles showed depleted DO concentrations below the thermocline during summer stratification indicating areas fish will likely avoid in summer months. Colder temperatures in fall caused complete mixing of the water column allowing fish to inhabit all depths of the lake. An inverse temperature stratification occurred directly below the ice during winter months as ice cover cooled the surface water to below 4 degrees Celsius. Ice cover also blocked air – water oxygen ...
