Bioelectrical Impedance Analysis Methods For Prediction Of Brook Trout Salvelinus Fontinalis Percent Dry Weight, Andrew William Hafs Dec 2011

Bioelectrical Impedance Analysis Methods For Prediction Of Brook Trout Salvelinus Fontinalis Percent Dry Weight, Andrew William Hafs

Graduate Theses, Dissertations, and Problem Reports

Reliable fish condition estimates are valued by fisheries ecologists and managers. Fish condition is used as an indicator of ecosystem health or to assess the population status for a species of interest. In aquaculture, proximate composition estimates are often wanted because of their relationship to fillet quality. Past researchers have used bioelectrical impedance analysis (BIA) to provide nonlethal mass based estimates of proximate composition for fish. Percent dry weight (PDW) of a fish is highly correlated to proximate composition values and energy density, therefore reliable predictions of PDW would eliminate the need for costly and laboratory analyses lethal to the …

Children completed several self-report measures on their parent's pressure and support behaviors in general and in soccer, …


Creating Reporter Systems Within Drosophila Melanogaster, Ashley Elizabeth Banks Dec 2011

Creating Reporter Systems Within Drosophila Melanogaster, Ashley Elizabeth Banks

Graduate Theses, Dissertations, and Problem Reports

The objective of these projects was to generate two fluorescently based systems within Drosophila melanogaster for the advancement of molecular research. The first project was aimed to create fluorescent phosphomimetic constructs of m8, a regulator in eye formation. The second project was to create a fluorescent visual marker for heterochromatic gene silencing in Drosophila. Proper formation of the eye requires that only one cell from a group of equipotent cells assumes a neural fate (the R8 cell). The cells surrounding the R8 cell are prevented from assuming this outcome through a process known as lateral inhibition. Lateral inhibition uses the …

Can Changes In Sr Protein Acetylation Affect Alternative Splicing?, Heather E. Knupp Dec 2011

Can Changes In Sr Protein Acetylation Affect Alternative Splicing?, Heather E. Knupp

Graduate Theses, Dissertations, and Problem Reports

Cellular phenotype and function is determined by the cellular proteome. Within the cellular proteome there are processes that have a potential to significantly alter the composition of the proteome. One such process is called alternative splicing. Splicing is the removal of introns from a pre-mRNA sequence and the remaining pre-mRNA sequences, called exons, are combined. Alternative splicing modifies the intron-exon combination, and can form novel products from the different arrangement of the coding sequences. This process, due to the high potential for new, possibly unwanted products, is highly regulated and can occur in a tissue and developmental-specific fashion. The misreguation …


Hydroclimatic Variability In North-Central Mongolia As Inferred From Tree Rings, Caroline Leland Dec 2011

Hydroclimatic Variability In North-Central Mongolia As Inferred From Tree Rings, Caroline Leland

Graduate Theses, Dissertations, and Problem Reports

The influence of increasing temperatures on hydrologic regimes across Mongolia is difficult to evaluate from a spatial perspective, particularly at fine resolutions. Therefore, networks of tree-ring chronologies are a valuable means of assessing regional and local variability in hydroclimate while placing recent moisture trends in a historical context. Tree-ring data are particularly useful in Mongolia, where instrumental records are spatially and temporally limited. Here, I present two chapters that are essentially related and complement one another. The first chapter seeks to identify tree-growth anomaly regions (i.e. inferred hydroclimatic regions) across north-central Mongolia based on a network of 21 tree-ring chronologies. …

The Social Transformation Of Coffee Houses: The Emergence Of Chain Establishments And The Private Nature Of Usage, Dawn Marie Lozzi

Graduate Theses, Dissertations, and Problem Reports

Much attention is given to Ray Oldenburg's (1989) concept of third places as environments that offer visitors friendship and a sense of community. However, given that coffee houses have moved from small-scale businesses to chain-owned and many people now use them to work on laptops, this idealized image of the coffee house also may be changing. Few empirical studies have addressed such possibilities. Using unobtrusive observation data on three independently-owned coffee houses and three chain-based coffee houses, this research examines the concept of third places to better understand the ways in which modern coffee houses live up to Oldenburg's social …

A Statistical Approach For Shadow Detection Using Spatio-Temporal Contexts, Yiyang Liu Dec 2011

A Statistical Approach For Shadow Detection Using Spatio-Temporal Contexts, Yiyang Liu

Graduate Theses, Dissertations, and Problem Reports

Background subtraction is an important step used to segment moving regions in surveillance videos. However, cast shadows are often falsely labeled as foreground objects, which may severely degrade the accuracy of object localization and detection. Effective shadow detection is necessary for accurate foreground segmentation, especially for outdoor scenes. Based on the characteristics of shadows, such as luminance reduction, chromaticity consistency and texture consistency, we introduce a nonparametric framework for modeling surface behavior under cast shadows. To each pixel, we assign a potential shadow value with a confidence weight, indicating the probability that the pixel location is an actual shadow point. …

Incorporating ecosystem restoration in forest management may be guided by goals and objectives based on known previous conditions and the range of natural variability of those conditions. …


Electron Paramagnetic Resonance And Electron-Nuclear Double Resonance Characterization Of Point Defects In Titanium Dioxide Crystals, Adam Brant Dec 2011

Electron Paramagnetic Resonance And Electron-Nuclear Double Resonance Characterization Of Point Defects In Titanium Dioxide Crystals, Adam Brant

Graduate Theses, Dissertations, and Problem Reports

Electron paramagnetic resonance (EPR) and electron-nuclear double resonance (ENDOR) are used to characterize several point defects in titanium dioxide (TiO2) single crystals in the rutile phase. A defect reported in 1961 by P. F. Chester called the "A Center" is assigned to a neutral hydrogen donor. Many researchers believe that the model for this S = 1/2 defect is an interstitial titanium ion (Ti3+) and that Ti3+ interstitials are the most dominant shallow donor in TiO 2. I show that the model for the A center is a neutral hydrogen donor and suggest that the Ti3+ interstitial model is not …

Repression Of Phlpp By Mir-190 Contributes To Arsenic-Induced Akt Activation And Carcinogenesis, Kevin John Beezhold Dec 2011

Repression Of Phlpp By Mir-190 Contributes To Arsenic-Induced Akt Activation And Carcinogenesis, Kevin John Beezhold

Graduate Theses, Dissertations, and Problem Reports

Arsenic is a well-studied human carcinogen. The mechanism by which arsenic induces cancer, however, is not fully understood. It is known that as a general stress inducer, arsenic can activate kinases, such as mitogen-activated protein kinases, leading to over activation of transcription factors. These transcription factors, including AP-1, NF-kB and Myc, are known to regulate the expression of early response genes, and likely to regulate miRNAs. The expression of miRNAs is often altered in cancer and other proliferative disorders. It is highly probable that miRNAs whose expressions are altered by arsenic will play a significant role in carcinogenesis. To test …

Characterization Of M-Cadherin's Role In Regulating Apoptosis And Myogenic Differentiation Of Myoblasts By Interacting With Key Components Of Canonical Wnt Signaling, Yan Wang

Graduate Theses, Dissertations, and Problem Reports

Activation, proliferation, and differentiation of satellite cells are the basic means for adult muscle regeneration. Apoptosis is concurrent to differentiation of satellite cells and dysregulated apoptosis contributes to the occurrence and progression of certain muscular dystrophies. This study investigated the role of M-cadherin-mediated signaling in regulating apoptosis versus survival of myoblasts during the process of myogenic differentiation. Inhibition of M-cadherin expression by RNAi (RNA interference) in confluent C2C12 myoblasts sensitized the cells to mitochondria-associated intrinsic apoptosis induced by either cell confluence or serum starvation. Manipulation of M-cadherin signaling regulated the Glycogen Synthase Kinase-3beta (GSK-3beta) activity via phosphoinositide-3 kinase (PI3K)/Akt pathway. …
