Laboratory And Field Investigations To Address Erosion, Volume Change And Desiccation Cracking Of Compost Amended Expansive Subsoils, Napat Intharasombat

Civil Engineering Dissertations - Archive

Desiccations cracks are formed during drying process of fine grained cohesive soils in summer and these cracks often appear on unpaved subgrades due to direct exposure to sun. These cracks allow surface runoff infiltration into subsoils and eventually weaken adjacent base and subgrade layers. The loss of support from these underlying layers results in both longitudinal and transverse cracks in paved shoulders and pavements. Composting is a successful method of recycling organic waste material into stabilized materials that could be used for erosion control and landscaping applications. Since compost is rich in fibrous material and exhibits moisture affinity characteristics, it …

Culture Of Obesity, Bridget Frugoli Melton

College of Graduate Studies: Theses & Dissertations

This dissertation sought to critically analyze the university environment by examining how the representation practices of corporations articulate with the growing obesity epidemic. For this study, existing data from one southeastern university was collected to describe the articulation between the university and obesity. The analysis examined the collected information and used the cultural studies concept of representation to expose the articulation between obesity and the university setting, including the three major theoretical works of Martin Nestle, Henry Giroux, Michel Foucault, and Paulo Freire. Physical fitness and dietary risk behaviors in students were described using the instrument of the 1995 National …

Dynamic Growth Rates Of Microbial Populations In Activated Sludge Systems, Peter George Stroot, Pascal E. Saikaly, Daniel B. Oerther

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Results of mathematical modeling and whole cell 16S ribosomal RNA-targeted fluorescence in situ hybridizations challenge the widely held perception that microbial populations in "steady-state" activated sludge systems share a common net growth rate that is proportional to the inverse of the mean cell residence time. Our results are significant because they encourage bioprocess engineers to appreciate the differences in growth physiology among individual microbial populations in complex mixed microbial communities such as suspended growth activated sludge bioreactor systems.

Diversity And Structure Of Bacterial Chemolithotrophic Communities In Pine Forest And Agroecosystem Soils, J. Tolli, G. M. King

Faculty Publications

Obligate lithotrophs (e.g., ammonia oxidizers) and facultative lithotrophs (e.g., CO and hydrogen oxidizers) collectively comprise a phylogenetically diverse functional group that contributes significantly to carbon and nitrogen cycles in soils and plays important roles in trace gas dynamics (e.g., carbon monoxide and nitrous and nitric oxides) that affect tropospheric chemistry and radiative forcing. In spite of their diverse physiologies, facultative and obligate lithotrophs typically possess the Calvin-Benson-Bassham cycle enzyme, ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisCO). In an effort designed to understand the structure of lithotrophic communities in soil, genomic DNA extracts from surface (0 to 2 cm) and subsurface (5 to 7 cm) …

Comparing Immune Responses Of Juvenile And Adult Northern Fence Lizards, Sceloporus Undulatus, Zaïna Sandrine Kabange

All-Inclusive List of Electronic Theses and Dissertations

Sex steroid hormones affect behavior and morphological traits important in sexual selection. Steroid hormones also play a role in the development and functioning of immune system components. The immunocompetence handicap hypothesis (Folstad and Karter, 1992) proposes that tradeoffs, mediated by plasma levels of testosterone, exist between the immune system and elaboration of secondary sexual traits. Endocrine-immune interactions are well documented in birds and mammals, and steroid hormones can be immunoenhancing or immunosuppressive. Relatively little work has examined the ontogeny of immune function, and the interactions between steroid hormones and the immune system in reptiles. The first experiment addressed the question …

Glycosylphosphatidylinositol-Anchored Proteins Are Required For Cell Wall Synthesis And Morphogenesis In Arabidopsis, C. Stewart Gillmor, Wolfgang Lukowitz, Ginger Brininstool, John C. Sedbrook, Thorsten Hamann, Patricia Poindexter, Chris Somerville

Faculty Publications

Mutations at five loci named PEANUT1-5 (PNT) were identified in a genetic screen for radially swollen embryo mutants, pnt1 cell walls showed decreased crystalline cellulose, increased pectins, and irregular and ectopic deposition of pectins, xyloglucans, and callose. Furthermore, pnt1 pollen is less viable than the wild type, and pnt1 embryos were delayed in morphogenesis and showed defects in shoot and root meristems. The PNT1 gene encodes the Arabidopsis thaliana homolog of mammalian PIG-M, an endoplasmic reticulum-localized mannosyltransferase that is required for synthesis of the glycosylphosphatidylinositol (GPI) anchor. All five pnt mutants showed strongly reduced accumulation of GPI-anchored proteins, suggesting that …

A Study Of How Precursor Key Concepts For Organic Chemistry Success Are Understood By General Chemistry Students, Patrick Gerard Meyer

Dissertations

This study examines college student understanding of key concepts that will support future organic chemistry success as determined by university instructors. During four one-hour individual interviews the sixteen subjects attempted to solve general chemistry problems. A think-aloud protocol was used along with a whiteboard where the students could draw and illustrate their ideas. The protocols for the interviews were adapted from the Covalent Structure and Bonding two-tiered multiple choice diagnostic instrument (Peterson, Treagust, & Garnett, 1989) and augmented by the Geometry and Polarity of Moleculessingle-tiered multiple choice instrument (Furió & Calatayud, 1996). The interviews were videotaped, transcribed, and coded …

Photoexcitation And Photoionization Of The Argon Atom And The Hydrogen Bromide Molecule, Ximao Feng

Dissertations

Interaction between synchrotron radiation with inner-shell electrons is a fundamental method to study the structure and dynamics of atoms and molecules. This thesis, under the guidance of Dr. Nora Berrah, concentrates on the study of the interaction between soft x-ray photons with Ar atoms and HBr moleculeswith time-of-flight (TOF) electron spectrometers and two-dimensional photoelectron spectroscopy (2DPES). Both of the experiments were performed on theAtomic, Molecular and Optical Physics undulator beamline at the Advanced Light Source at Lawrence Berkeley National Laboratory.

The argon study focused on photoelectron recapture when the 2p electrons are ionized just above the thresholds of the two …

Paleoenvironmental Reconstruction Of The Late Cretaceous Eastern Gulf Coastal Plain In Georgia And Alabama, Tracy L. Hall

Theses and Dissertations

The present study reconstructs the regional paleoenvironment (particularly paleoclimate) of the Late Cretaceous Eastern Gulf Coastal Plain of Georgia and Alabama using paleobotanical, paleoecological and geochemical methods in order to evaluate the Late Cretaceous climate of the Southeastern United States, and to add to the body of paleoclimate data for that time. Paleobotanical analysis indicates a terrestrial mean annual temperature (MAT) of about 27°C during the Late Cretaceous, which is considerably warmer than modern terrestrial MAT. Stable oxygen isotope data from molluscan carbonate indicate mean sea surface temperature (SST) of 26.8 °C for the Santonian, 23.5°C for the early Campanian, …

Limited Dispersal And Heterogeneous Predation Risk Synergistically Enhance Persistence Of Rare Prey, Brett J. Goodwin, Clive G. Jones, Eric M. Schauber, Richard S. Ostfeld

Publications

White-footed mice prey on gypsy moth pupae while foraging for other, more abundant food. Mice appear capable of locally extirpating moths since mice exert high predation pressure on sparse pupae and are numerically decoupled from moth populations. Nevertheless, during 23 years of monitoring, moths persisted at scales .1 ha despite frequent extinctions at smaller spatial scales. We hypothesized that spatially heterogeneous intensity in mouse foraging and/or limited moth dispersal might allow moth persistence. Using a spatially explicit, individual-based, empirically parameterized model, we show that neither spatially heterogeneous predation by mice, nor limited moth dispersal alone allows moth persistence at typical …

Cryopreservation Of Human Hematopoietic Stem And Progenitor Cells Loaded With Trehalose: Transient Permeabilization Via The Adenosine Triphosphate-Dependent P2z Receptor Channel, Sandhya S. Buchanan, Michael A. Menze, Steven C. Hand, David W. Pyatt, John F. Carpenter

Faculty Publications

Hematopoietic stem and progenitor cells (HPCs) are a heterogenic population of cells used to treat a number of human diseases. Multilineage differentiation is a required function in successful hematopoietic reconstitution after transplantation of cryopreserved grafts. Conventional use of the cryoprotectant dimethyl sulfoxide (DMSO) has resulted in some reports of infusion related toxicity attributed to DMSO and/or damage to cells during freeze-thawing procedures. The purpose of this study was to explore the use of trehalose, a nontoxic disaccharide of glucose, as an alternative cryoprotectant. Trehalose was introduced into HPCs using the P2Z receptor, known to form nonselective pores in the presence …

A Mobile Element Based Phylogeny Of Old World Monkeys, Jinchuan Xing, Hui Wang, Kyudong Han, David A. Ray, Cheney H. Huang, Leona G. Chemnick, Caro Beth Stewart, Todd R. Disotell, Oliver A. Ryder, Mark A. Batzer

Faculty Publications

SINEs (Short INterspersed Elements) are a class of non-autonomous mobile elements that are states, making them useful genetic systems for phylogenetic studies. Alu elements are the most successful SINE in primate genomes and have been utilized for resolving primate phylogenetic relationships and human population genetics. However, no Alu based phylogenetic analysis has yet been performed to resolve relationships among Old World monkeys. Using both a computational approach and polymerase chain reaction display methodology, we identified 285 new Alu insertions from sixteen Old World monkey taxa that were informative at various levels of catarrhine phylogeny. We have utilized these elements along …

Ecotoxicology And Environmental Education In The Development Of A Turtle Conservation Program In Southeastern Tennessee, Stefan L. Moss

Masters Theses and Doctoral Dissertations

In 1999, the Tennessee Aquarium initiated a long-term mark-recapture study to promote the conservation of freshwater turtles in the Tennessee River Gorge (TRG). The TRG consists of a 42-kilometer stretch of the Tennessee River surrounded by 27,000 acres (11,000 hectares) and is known as the "Grand Canyon of Tennessee." In 2002, the Aquarium established a partnership with The University of Tennessee at Chattanooga (UTC) and the Tennessee River Gorge Trust (TRGT) to expand the program. Since then, researchers at UTC have been conducting scientific research at the TRG each year in an effort to increase the amount of available information …

Detecting And Mapping The Michigan Vegetation Tension Zone Using Ecological Indicators, Janice Marie Fulford

Masters Theses

Ecotones are areas of transition between adjacent ecosystems that exist at various geographic scales, and are useful in measuring climatic changes. Ecotones are defined by their length and breadth and the ability to detect and map an ecotone from a specific period in time would be useful in measuring current and future change.

The study focused on a 1880's vegetation ecotone in the center of Michigan's Lower Peninsula. This was achieved by deriving ecological variables from the U.S. public land survey's tree species data. These variables were then used to ascertain the length of the ecotone by finding the boundary …

Loss Of Nitrate-Nitrogen By Runoff And Leaching For Agricultural Watersheds, M. A. Elrashidi, M. D. Mays, A. Fares, C. A. Seybold, J. L. Harder, S. D. Peaslee, Pam Vanneste

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The loss of nutrients in runoff and leaching water from agricultural land is a major cause of poor water quality in the United States. Scientists (NRCS) developed a technique to estimate the impact of agricultural watersheds on natural water resources. The objectives were to apply the technique on Wagon Train (WT) watershed in Nebraska to predict: (i) loss of water by surface runoff and subsurface leaching, (ii) loss of nitrate-N from soils by runoff and leaching, and (iii) nitrate-N loading for WT reservoir. The annual loss of water was estimated at 4.32 million m³ for runoff and 0.98 million …

Comparison Of Glomalin And Humic Acid In Eight Native U.S. Soils, K. A. Nichols, S. F. Wright

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Two important extractable fractions of soil organic matter (SOM) are humic acid (HA) and glomalin-related soil protein (glomalin). Optimizing the purity of each fraction is necessary to correlate fraction quantity and molecular characteristics with soil quality. Manipulation of extraction sequence and controlled precipitation of HA were used to evaluate co-extraction of HA and glomalin. Eight bulk soil samples (0 to 10 cm depth) were collected from four U.S. states (Colorado, Nebraska, Maryland, and Georgia). In Experiment 1, glomalin extraction (50 mM citrate, pH 8.0, at 121 'C) was followed by HA extraction (0.1 N NaOH at room temperature), and Experiment …

Carbon Isotope Of Bulk Organic Matter: A Proxy For Precipitation In The Arid And Semiarid Central East Asia, Xinqing Lee, Zhaodong Feng, Lanlan Guo, Lixia Wang, Liya Jin, Yongsong Huang, Mark Chopping, Daikuan Huang, Wei Jiang, Qian Jiang, Hongguang Cheng

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Carbon isotope composition (δ13C) of bulk organic matter in soil and lake sediment sequences has been widely used to infer past climate changes. The specific climatic representation of the isotopic signature, however, lacks for examination. With excellent gradients of temperature and precipitation, as well as the gradients of vegetation zone, central East Asia provides an ideal background for developing the relationship between the δ13C and the climatic parameters. Analysis of surface soil organic matter from a transect that crosses the various climatic and vegetation zones reveals a significant linear correlation between δ13C and the mean precipitation from May to September …
