Bioswellable Amphiphilic Copolymers, David Ingram Dec 2012

Bioswellable Amphiphilic Copolymers, David Ingram

All Theses

The suture is one of the most commonly used medical devices, consisting of a fiber, a surgical needle and the packaging in which it is stored. The fiber itself remains after implantation for a defined time and is responsible for the approximation of the wound during the healing process. The needle merely serves to aid in insertion, and preferably has a diameter larger than the diameter of the fiber .
The 1970's marked the birth of a new family of fibrous materials for the approximation of wounds: synthetic absorbable sutures. This family has the ability to provide wound support during …

Civil and Environmental Engineering Faculty Publications

Ammonia (NH3) is an important trace gas species in the atmosphere that can have negative impacts on human, animal, and ecosystem health. Agriculture has been identified as the largest source of NH3, specifically livestock operations. NH3 emissions from a commercial dairy in California were investigated during June 2008. Cattle were held in open-lot pens, except for young calves in hutches with shelters. Solid manure was stored in the open-lot pens. Liquid manure from feed lanes was passed through a solids settling basin and stored in a holding pond. Passive sensors and open-path Fourier transform infrared spectrometers (OP-FTIR) were deployed around …

Impact Of Sampling Frequency On Annual Load Estimation Of Total Phosphorus And Total Suspended Solids, Amber Spackman Jones, Jeffery S. Horsburgh, David King Stevens, Nancy O. Mesner, Ronald J. Ryel Dec 2012

Impact Of Sampling Frequency On Annual Load Estimation Of Total Phosphorus And Total Suspended Solids, Amber Spackman Jones, Jeffery S. Horsburgh, David King Stevens, Nancy O. Mesner, Ronald J. Ryel

Civil and Environmental Engineering Faculty Publications

The determination of sediment and nutrient loads is typically based on the collection and analysis of grab samples. The frequency and regularity of traditional sampling may not provide representation of constituent loading, particularly in systems with flashy hydrology. At two sites in the Little Bear River, Utah, continuous, high-frequency turbidity was used with surrogate relationships to generate estimates of total phosphorus and total suspended solids concentrations, which were paired with discharge to estimate annual loads. The high frequency records were randomly subsampled to represent hourly, daily, weekly, and monthly sampling frequencies and to examine the effects of timing, and resulting …

Analysis Of Genotype, Phenotype, And Age Progression In Phelan-Mcdermid Syndrome, Sara Sarasua Dec 2012

Analysis Of Genotype, Phenotype, And Age Progression In Phelan-Mcdermid Syndrome, Sara Sarasua

All Dissertations

Phelan-McDermid syndrome is a developmental disability syndrome associated with deletions of the terminal end of one copy of chromosome 22q13. The observed chromosomal aberrations include simple terminal deletions, interstitial deletions, deletions and duplications, and duplications without deletions. All patients have some degree of developmental disability and many also have hypotonia, autism, minor dysmorphic features, and seizures. I performed an epidemiological and cytogenetic investigation to better understand the etiology of Phelan-McDermid syndrome and to provide information to patients and their families, clinicians, and researchers investigating developmental disabilities. Deletions vary widely in size, from 60 kb to more than 9 Mb, but …

Molecular Genetics Of Nodule Number Regulation: Cloning, Characterization And Functional Studies Of The Root Determined Nodulator1 (Rdn1) Gene In Medicago Truncatula, Tessema Kassaw Dec 2012

Molecular Genetics Of Nodule Number Regulation: Cloning, Characterization And Functional Studies Of The Root Determined Nodulator1 (Rdn1) Gene In Medicago Truncatula, Tessema Kassaw

All Dissertations

Nitrogen is critical to life. However, the majority of nitrogen on earth (in the atmosphere) is inert and unavailable to nearly all organisms. Metabolically diverse prokaryotes are the only organisms capable of fixing atmospheric nitrogen; rhizobia set up a symbiosis with legume plants allowing the plants to benefit from this ability. Since nodulation and the subsequent nitrogen fixation processes are energy intensive, the host plant must balance hosting of the rhizobia by limiting the number of nodules it forms through a mechanism called Autoregulation of Nodulation (AON). My study of mutants in the model legume Medicago truncatula defective in AON …

Sorption And Enantiomerization Of Current Use Chiral Pesticides, April Hall Dec 2012

Sorption And Enantiomerization Of Current Use Chiral Pesticides, April Hall

All Dissertations

Chiral pesticides are prevalent in the environment today and are known to react selectively with chiral environmental components such as microbes, enzymes, and other naturally occurring chiral materials. In addition, chiral sorption is a process that has been occasionally investigated in the study of homochirality (the exclusive presence of one enantiomer in living organisms), but almost overlooked in environmental science. For chiral sorption to occur, the sorbent and sorbate must be chiral entities. In the environment, there are abundant natural surfaces that are chiral, including clay minerals and organic matter present in soil, sediment and aqueous solution. A knowledge of …

Sample Preparation Techniques For The Improvement Of Analytical Measurements: Capillary-Channeled Polymer Fibers Employed In Protein Solid Phase Extraction Applications And Characterization Of Active Components In Botanical Dietary Supplements, Carolyn Burdette Dec 2012

Sample Preparation Techniques For The Improvement Of Analytical Measurements: Capillary-Channeled Polymer Fibers Employed In Protein Solid Phase Extraction Applications And Characterization Of Active Components In Botanical Dietary Supplements, Carolyn Burdette

All Dissertations

The task of sample preparation encompasses many challenges and demands for analytical techniques. Appropriate preparative steps can be the determining factor between successful measurements and failures. Too little preparation can lead to the inability to detect analytes due to low concentrations, insufficient extraction of analytes, and/or strong matrix effects; exhaustive preparation steps increases analysis times, the potential for analyte losses, and the difficulty to obtain consistent reproducible results. Discussed here are several examples of analytical techniques where sample preparation is critical and can be used to improve existing techniques. Capillary-channeled polymer (C-CP) fibers used for solid phase extraction (SPE) protein …

Develop Novel Frap Techniques For Determining Anisotropic Solute Diffusion In Cartilaginous Tissues, Changcheng Shi Dec 2012

Develop Novel Frap Techniques For Determining Anisotropic Solute Diffusion In Cartilaginous Tissues, Changcheng Shi

All Dissertations

Cartilaginous tissue is a connective tissue composed of specialized cells (e.g., chondrocytes and fibroblasts) that produce a large amount of extracellular matrix (ECM), which is comprised mostly of collagen fibers, abundant ground substance rich in proteoglycan, and elastic fibers. It is characterized by its avascular structures within the tissue, implying that nutrition for normal tissue cells, for maintaining a healthy ECM, is mainly supplied through diffusion from nearby vascularized tissues and synovial fluid. Poor nutritional supply to the cartilaginous tissue is believed to be an important factor leading to tissue degeneration. Moreover, due to the complex collagen fiber structures, the …

Spider Mediation Of Polychlorinated Biphenyl Transport And Transformation Across Riparian Ecotones, Diana Delach Dec 2012

Spider Mediation Of Polychlorinated Biphenyl Transport And Transformation Across Riparian Ecotones, Diana Delach

All Dissertations

Polychlorinated biphenyls (PCBs) contaminate the sediment of the Twelvemile Creek / Lake Hartwell Superfund Site, and are known to be transported throughout the resident biota via trophic transport. Riparian spiders have recently become of interest because they are terrestrial organisms that have significant PCB exposures derived from aquatic sources. Many riparian spiders primarily consume insects emerging from contaminated aquatic systems, and these spiders can have a body burden as high as 2900 ng/g lipid. These emergent insects carry contaminants out of the river and into the riparian zone where they are captured by spiders, which effectively directs the contamination towards …

Analyses Of Consumer Perceptions, Farmer Challenges, Polyamine, And Amino Acid Content Of Organic And Conventional Fresh Produce Grown In South Carolina, Emily Steinberg Dec 2012

Analyses Of Consumer Perceptions, Farmer Challenges, Polyamine, And Amino Acid Content Of Organic And Conventional Fresh Produce Grown In South Carolina, Emily Steinberg

All Dissertations

Execution of the USDA organic standards led to more support for local food as distinct from organic food. The current study was conducted to examine fresh produce perceptions and purchasing decisions of S.C. consumers. Four-hundred and eight S.C. consumers were surveyed at S.C. grocery stores. More than one-third of the S.C. consumers not knowing about the 'certified S.C. grown' program suggest that the S.C. Department of Agriculture (SCDA) may want to improve the promotion of their program. Eighty-five percent of consumers indicated that they would choose local over organic. This information would be useful to local S.C. produce farmers who …

Application Of Carbon Dioxide Towards The Development Of Smart Materials, Green Reaction Schemes And Metallic Nanoparticle Synthesis, Fiaz Mohammed

All Dissertations

Global carbon dioxide (CO2) emissions have steadily risen over the last 50 years, with 34 billion tons of CO2 released in 2009 alone. Its potential as a greenhouse gas has negatively affected of our lives and environment by the resulting ocean acidification and climate change. To mitigate atmospheric CO2, various strategies have been implemented for CO2 separation, capture, storage and use as a chemical feedstock. The use of CO2 in various chemical industries is attractive as its non-flammable, non-toxic, and relatively inert properties have made it an inherently safer alternative to traditional organic …

The Behavior And Toxicity Of Metal Oxide Nanoparticles In Aqueous Solution, Phenny Mwaanga Dec 2012

The Behavior And Toxicity Of Metal Oxide Nanoparticles In Aqueous Solution, Phenny Mwaanga

All Dissertations

The dissolution and aggregation of metal oxides nanoparticles (NPs) in aqueous solution not only alter the abundance and toxicology of NPs, but also makes the effective assessment and the correct interpretation of effects of NPs on organisms challenging. The extent to which these processes (dissolution and aggregation) occur largely depend on pH, ionic strength, dissolved natural organic matter (NOM) and NPs characteristics. This study investigated the dissolution and aggregation behavior of the four metal oxide NPs (nZnO, nCuO, nFe2O3 and nTiO2) in aqueous solution as influenced by pH, ionic strength and NOM and examined the toxicity of these NPs to …

The Contribution Of Poly(Adp-Ribose)Polymerase-1 Activity In The Nucleotide Excision Repair Pathway, Brenee S. King Dec 2012

The Contribution Of Poly(Adp-Ribose)Polymerase-1 Activity In The Nucleotide Excision Repair Pathway, Brenee S. King

Biomedical Sciences ETDs

Exposure to ultraviolet radiation (UVR) promotes the formation of UVR-induced, DNA helix distorting photolesions such as (6-4) pyrimidine-pyrimidone photoproducts (6-4 PPs) and cyclobutane pyrimidine dimers (CPDs). Effective repair of such lesions by the nucleotide excision repair (NER) pathway is required to prevent DNA mutations and chromosome aberrations. Poly(ADP-ribose)polymerase-1 (PARP-1) is a zinc-finger protein with well documented involvement in base excision repair (BER). PARP-1 is activated in response to DNA damage and catalyzes the formation of poly(ADP-ribose) subunits (PAR) that assist in the assembly of DNA repair complexes at sites of damage. In this dissertation, I present evidence for PARP-1 contributions …

Gene Duplication And The Evolution Of Hemoglobin Isoform Differentiation In Birds, Michael T. Grispo Dec 2012

Gene Duplication And The Evolution Of Hemoglobin Isoform Differentiation In Birds, Michael T. Grispo

School of Biological Sciences: Dissertations, Theses, and Student Research

The majority of bird species co-express two functionally distinct hemoglobin (Hb) isoforms in definitive erythrocytes: HbA (the major adult Hb isoform, with α-chain subunits encoded by the αA-globin gene) and HbD (the minor adult Hb isoform, with α-chain subunits encoded by the αD-globin gene). The αD-globin gene originated via tandem duplication of an embryonic α-like globin gene in the stem lineage of tetrapod vertebrates, which suggests the possibility that functional differentiation between the HbA and HbD isoforms may be attributable to a retained ancestral character state in HbD that harkens back to a primordial, …

Transcriptional Analysis Of Cervical Epithelial Cell Responses To Hiv-1, Andrew A. Block Dec 2012

Transcriptional Analysis Of Cervical Epithelial Cell Responses To Hiv-1, Andrew A. Block

School of Biological Sciences: Dissertations, Theses, and Student Research

Human Immunodeficiency Virus type 1 (HIV-1) infection causes a growing pandemic throughout the world, of which women comprise 51% of people who live with HIV-1, more than 60% in sub-Saharan Africa. HIV-1 infections of women are mainly acquired through female reproductive tract where cervical and vaginal epithelial cells are the first line of defense. Although HIV-1 does not directly infect epithelial cells, HIV-1 obligatorily interacts with and crosses over epithelial layer to infect susceptible target cells, mainly CD4+ T cells, in the lamina propria to initiate an infection. However, the mechanism and ramification of the interaction of HIV-1 and epithelial …

Designing Selection Systems For Medicine: The Importance Of Balancing Predictive And Political Validity In High-Stakes Selection Contexts, Fiona Patterson, Filip Lievens, Máire Kerrin, Lara Zibarras, Bernd Carette Dec 2012

Designing Selection Systems For Medicine: The Importance Of Balancing Predictive And Political Validity In High-Stakes Selection Contexts, Fiona Patterson, Filip Lievens, Máire Kerrin, Lara Zibarras, Bernd Carette

Research Collection Lee Kong Chian School Of Business

Selection into medical education and training is a high-stakes process. A key unanswered issue is the effectiveness of measuring noncognitive predictors via both low-fidelity and high-fidelity selection approaches in this high-stakes context. We review studies investigating the effectiveness of multiple selection instruments in terms of predictive validity, incremental validity, and applicant reactions in both entry-level and advanced-level medical selection. Our results show that the situational judgment test (SJT) is the best single predictor of performance, operationalized in multiple ways. In addition, the low-fidelity SJT has incremental predictive power over cognitively oriented tests, and high-fidelity assessment center (AC) exercises add incremental …

Grandparents As Guards: A Game Theoretic Analysis Of Inheritance And Post Marital Residence In A World Of Uncertain Paternity, Brishti Guha Dec 2012

Grandparents As Guards: A Game Theoretic Analysis Of Inheritance And Post Marital Residence In A World Of Uncertain Paternity, Brishti Guha

Research Collection School Of Economics

I unify the following (1) men face paternal uncertainty while women do not face maternal uncertainty, (2) putative fathers and paternal kin care about true paternity, (3) paternity confidence is systematically lower in matrilocal cultures than in patrilocal ones, (4) inheritance tends to be patrilineal in high paternity confidence cultures and matrilineal in low confidence ones, and (5) most societies with patrilineal inheritance were patrilocal while most societies with matrilineal inheritance were matrilocal. I model the co-evolution of inheritance patterns and post-marital residence patterns - and their relationship with paternity uncertainty. Using a game theoretic model, I examine how a …

B-Cell Epitope Prediction Through A Graph Model, Liang Zhao, Limsoon Wong, Lanyuan Lu, Steven C. H. Hoi, Jinyan Li Dec 2012

B-Cell Epitope Prediction Through A Graph Model, Liang Zhao, Limsoon Wong, Lanyuan Lu, Steven C. H. Hoi, Jinyan Li

Research Collection School Of Computing and Information Systems

Prediction of B-cell epitopes from antigens is useful to understand the immune basis of antibody-antigen recognition, and is helpful in vaccine design and drug development. Tremendous efforts have been devoted to this long-studied problem, however, existing methods have at least two common limitations. One is that they only favor prediction of those epitopes with protrusive conformations, but show poor performance in dealing with planar epitopes. The other limit is that they predict all of the antigenic residues of an antigen as belonging to one single epitope even when multiple non-overlapping epitopes of an antigen exist.

Interior Least Tern Powerline Collision On The Lower Platte River, Lauren R. Dinan, Joel G. Jorgensen, Mary Bomberger Brown Dec 2012

Interior Least Tern Powerline Collision On The Lower Platte River, Lauren R. Dinan, Joel G. Jorgensen, Mary Bomberger Brown

The Prairie Naturalist

Collisions with electrical powerlines are a well-known documented cause of avian mortality (Avian Power Line Interaction Committee [APLIC] 1994, Savereno et al. 1996). Mortality caused by collisions with powerlines can be an important concern for many bird species, but is a serious conservation problem for threatened and endangered species because any mortality can have biological and legal ramifications (Janss 2000). Loss of individuals, particularly breeding adults, from an already small population may impede a species’ recovery by reducing reproduction and recruitment into the breeding population. The death of an individual from a threatened or endangered species as a result of …

Avian Diversity And Habitat Use On Wetland Reserve Program Lands In The Lower Missouri River Valley, Eric C. Hopps Dec 2012

Avian Diversity And Habitat Use On Wetland Reserve Program Lands In The Lower Missouri River Valley, Eric C. Hopps

The Prairie Naturalist

A primary objective of the Wetland Reserve Program (WRP) is to provide habitat for migratory birds throughout all seasons of the year. Comprehensive avian assessments are lacking and limit our ability to evaluate the benefits of the WRP to continental bird populations. I investigated avian species occurrence on WRP lands within the Lower Missouri River Valley (LMRV), Nebraska, USA, from March 2010 to February 2011. Ten WRP habitat types are described based on plant community assemblages and observed hydrological regimes. Estimates of avian species richness were greatest in lowland forest (n = 115), lowland woodland (n = 83) and upland …

Fish Assemblage Structure In Black Hills, South Dakota Streams, Luke D. Schultz, Sarah J. Lewis, Katie Nicole Bertrand Dec 2012

Fish Assemblage Structure In Black Hills, South Dakota Streams, Luke D. Schultz, Sarah J. Lewis, Katie Nicole Bertrand

The Prairie Naturalist

Understanding factors structuring fish assemblages in a particular area is valuable to both sport fishery management and native species conservation. Fish assemblages in the Black Hills are unique to South Dakota because they contain economically valuable introduced salmonids as well as native species of conservation need. Our objective was to examine the relationship between fish assemblages and geomorphic and reach-scale habitat features across multiple stream reaches in the Black Hills. Canonical correspondence analysis, a direct gradient ordination analysis, indicated that factors operating at multiple spatial scales interacted to structure fish assemblages. There also was indication of segregation between native species …

Walleye Trophic Position Before And After A Gizzard Shad Extirpation, Bethany J. Bethke, Justin A. Vandehey, Mark J. Fincel, Brian D.S. Graeb, Mark T. Porath

The Prairie Naturalist

Walleye (Sander vitreus) are an ecologically and recreationally important sport fish species. Reduced growth and condition in walleye can occur when prey availability is limited. In two Nebraska reservoirs, walleye consumed gizzard shad (Dorosoma cepedianum) as their primary prey until a winterkill extirpated the gizzard shad in 2001. Because of the winterkill, walleye in the two reservoirs had to change to alternative prey items. Our objective was to determine if stable isotope analysis on archived walleye scales can be used to detect a known food web shift in two reservoir food webs. We quantified the changes …

The Age Of Marital Capacity: Reconsidering Civil Recognition Of Adolescent Marriage, Vivian E. Hamilton Dec 2012

The Age Of Marital Capacity: Reconsidering Civil Recognition Of Adolescent Marriage, Vivian E. Hamilton

Faculty Publications

Age at marriage has for decades been the strongest and most unequivocal predictor of marital failure. The likelihood of divorce nears eighty percent for those who marry in mid-adolescence, then drops steadily. Delaying marriage until the mid-twenties reduces one’s likelihood of divorce to thirty percent. Women who marry at age twenty-one or younger, moreover – and one in ten U.S. women do – experience worse mental and physical health, attain less education, and earn lower wages than those who marry later. Post-divorce, they and their children tend to endure even greater economic deprivation and instability than do never-married mothers, who …
