Contributions Of Unique Active Site Residues Of Eukaryotic Udp-Galactopyranose Mutases To Substrate Recognition And Active Site Dynamics, Isabel Da Fonseca, Insaf A. Qureshi, Ritcha Mehra-Chaudhary, Karina Kizjakina, John J. Tanner, Pablo Sobrado

Chemistry Faculty Research & Creative Works

UDP-glucopyranose mutase (UGM) catalyzes the interconversion between UDP-galactopyranose and UDP-galactofuranose. Absent in humans, galactofuranose is found in bacterial and fungal cell walls and is a cell surface virulence factor in protozoan parasites. For these reasons, UGMs are targets for drug discovery. Here, we report a mutagenesis and structural study of the UGMs from Aspergillus fumigatus and Trypanosoma cruzi focused on active site residues that are conserved in eukaryotic UGMs but are absent or different in bacterial UGMs. Kinetic analysis of the variants F66A, Y104A, Q107A, N207A, and Y317A (A. fumigatus numbering) show decreases in kcat/KM values of 200-1000-fold for the …


Engaging Fyc Students With Quality Work Design, Candace Deal Dec 2014

Engaging Fyc Students With Quality Work Design, Candace Deal

Master of Arts in Professional Writing Capstones

Students learn at deeper levels when engaged with their work; however, engaging students in writing is one of the biggest challenges all composition teachers face. This qualitative study asked Kennesaw State University students to describe the work in English 1101 and English 1102 that they found meaningful and engaging. The data collected was then aligned with research about engaging students in grades K-12 based on the work of Phillip Schlechty. Results from this study reveal that many of the same engagement qualities identified by Schlechty have application in the FYC classroom for engaging students and improving learning.


Professional Learning And Lean Manufacturing, Parker Grant Dec 2014

Professional Learning And Lean Manufacturing, Parker Grant

Doctoral Dissertations

Global competition and a down-sized labor force require manufacturers to use lean manufacturing practices. Current professional development models, however, are suboptimal in guiding efforts of first line supervisors to help workers improve their skills in solving manufacturing problems. This study employed an interpretive qualitative research methodology to explore what supervisors and workers experienced as the key factors that helped workers learn how to use lean manufacturing practices. Eight individuals who worked in an aerospace manufacturing plant located in the northeast United States participated in the study. Six of the participants were first line supervisors and two were first-line workers. Data …


A Content-Sensitive Wiki Help System, Eswara Satya Pavan Rajesh Pinapala Dec 2014

A Content-Sensitive Wiki Help System, Eswara Satya Pavan Rajesh Pinapala

Master's Projects

Context-sensitive help is a software application component that enables users to open help pertaining to their state, location, or the action they are performing within the software. Context-sensitive “wiki” help, on the other hand, is help powered by a wiki system with all the features of context-sensitive help. A context-sensitive wiki help system aims to make the context-sensitive help collaborative; in addition to seeking help, users can directly contribute to the help system. I have implemented a context-sensitive wiki help system into Yioop, an open source search engine and software portal created by Dr. Chris Pollett, in order to measure …


Biological And Physiological Condition Of Juvenile California Halibut (Paralichthys Californicus) Exposed To A Contamination Gradient In Mission Bay, Ca, Kevin Stolzenbach Dec 2014

Biological And Physiological Condition Of Juvenile California Halibut (Paralichthys Californicus) Exposed To A Contamination Gradient In Mission Bay, Ca, Kevin Stolzenbach

Theses

Contaminated sediments in marine environments have been shown to be good indicators of ecological risk and a means to assess anthropogenic impacts on marine habitats and the animals that inhabit them (Long et al. 1995, Rattner 2009). Estuarine sediments are especially complex media with regard to physical, chemical, and biological characteristics that trap, store, modify and sometimes release contaminants to the biota (Long et al. 1995). Especially vulnerable are animals that are in constant contact with the sediments, such as flatfishes that partially bury themselves for camouflage (Costa et al. 2011). Impacts can be assessed in a number of ways, …


Distributions Of Ice Supersaturation And Ice Crystals From Airborne Observations In Relation To Upper Tropospheric Dynamical Boundaries, Minghui Diao, Jorgen Jensen, Laura Pan, Cameron Homeyer, Shawn Honomichl, James Bresch, Aaron Bansemer, Eric Jensen Dec 2014

Distributions Of Ice Supersaturation And Ice Crystals From Airborne Observations In Relation To Upper Tropospheric Dynamical Boundaries, Minghui Diao, Jorgen Jensen, Laura Pan, Cameron Homeyer, Shawn Honomichl, James Bresch, Aaron Bansemer, Eric Jensen

Faculty Publications, Meteorology and Climate Science

Cirrus clouds are one of the largest sources of uncertainties in predicting future climate. Ice nucleation and ice crystal growth inside cirrus clouds require ice supersaturation (ISS). Previously, remote sensing observations have shown that the locations of cirrus clouds’ cloud top height are highly correlated with the thermal tropopause height (Pan and Munchak, 2011). However, it is unclear if the initial conditions of cirrus clouds – ice supersaturated region (ISSRs) – have similar features in the extratropical upper troposphere and lower stratosphere (UT/LS). In fact, the dynamical processes and conditions that contribute to ISS formation from the microscale (~100 m) …


Women In Kazakhstan: A Multifaceted Approach To Female Political Representation, Ashley Gaile Benedict Dec 2014

Women In Kazakhstan: A Multifaceted Approach To Female Political Representation, Ashley Gaile Benedict

Dissertations

This investigation focuses on two competing theories (historical institutionalism and social constructivism) and their explanatory value in regards to female political representation in Kazakhstan. Historical Institutionalism maintains that current institutional dynamics are constrained by past institutional formations, even when these past institutions are no longer relevant. Social Constructivism challenges this theory by upholding that institutions are culturally situated and a reflection of shared ideas rather than material forces as argued by historical institutionalism. Based on Hanna Pitkin’s (1967) four dimensions of representation (formal, descriptive, substantive, and symbolic), I examine how Kazakhstan’s Soviet past and its creation of a Kazakh ethnic-national …

Style Shifting In First-Encounter Conversations Between Japanese Speakers, Kenichi Shinkuma Dec 2014

Style Shifting In First-Encounter Conversations Between Japanese Speakers, Kenichi Shinkuma

Dissertations and Theses

This study examines style shift between formal and informal styles in first- encounter conversations between Japanese native speakers and demonstrates how the speakers shifted the speech style in the context. Many researchers have studied this type of style shift and demonstrated that style shifts occur within a single speech context where social factors, such as differences in age, status, and formalness remain constant (e.g., Cook, 2008; Geyer, 2008; Ikuta, 1983; Maynard, 1991; Okamoto, 1999). This study contributed support to these previous studies. In this study, both quantitative and qualitative analyses focusing on Japanese native speakers' use of style shifting in …


The Nax Language: Unifying Functional Programming And Logical Reasoning In A Language Based On Mendler-Style Recursion Schemes And Term-Indexed Types, Ki Yung Ahn Dec 2014

The Nax Language: Unifying Functional Programming And Logical Reasoning In A Language Based On Mendler-Style Recursion Schemes And Term-Indexed Types, Ki Yung Ahn

Dissertations and Theses

Two major applications of lambda calculi in computer science are functional programming languages and mechanized reasoning systems (or, proof assistants). According to the Curry--Howard correspondence, it is possible, in principle, to design a unified language based on a typed lambda calculus for both logical reasoning and programming. However, the different requirements of programming languages and reasoning systems make it difficult to design such a unified language that provides both. Programming languages usually extend lambda calculi with programming-friendly features (e.g., recursive datatypes, general recursion) for supporting the flexibility to model various computations, while sacrificing logical consistency. Logical reasoning systems usually extend …

Multivariate Remote Process Sensing For Online Quality Control Of Injection Molding, Xinyao Tang Dec 2014

Multivariate Remote Process Sensing For Online Quality Control Of Injection Molding, Xinyao Tang

Master's Theses

A new wireless multivariate sensor (MVS) is designed, prototyped, structurally embedded into a mold structure to provide in situ feedback of four process states within mold cavity: melt temperature, melt pressure, melt velocity and melt viscosity, which closely correlate to the quality of manufactured products through the constitutive viscoelastic behavior of the polymer being processed. The developed MVS enables the improved observability of injection molding and provides a new process instrumentation and control methodology that sets up, assures, and optimizes the quality of injected products. Relationship between the key in-process states and quality characteristics (e.g., thickness and width of the …

Identification And Functional Analysis Of Alternatively Spliced Isoforms Of Soluble Adenylyl Cyclase In Human Bronchial Epithelial Cells, Xi Chen Dec 2014

Identification And Functional Analysis Of Alternatively Spliced Isoforms Of Soluble Adenylyl Cyclase In Human Bronchial Epithelial Cells, Xi Chen

Open Access Dissertations

Effective ciliary beating is one of the key factors that regulate mucociliary clearance. Ciliary beat frequency (CBF) is partly regulated by changes in intracellular calcium and cyclic adenosine monophosphate (cAMP). While transmembrane adenylyl cyclases (tmACs) are well known for their ability to produce cAMP upon activation, soluble adenylyl cyclase (sAC) is another source of cAMP production mediated specifically by HCO3-/CO2. It contributes to CBF regulation and the prevention of lung diseases due to mucociliary dysfunction. The three known alternatively spliced isoforms of sAC were identified in mice and rats, but there was no systematic study aimed at identifying additional alternatively …


Transferential Poetics, From Poe To Warhol, Adam Frank Dec 2014

Transferential Poetics, From Poe To Warhol, Adam Frank

Literature

Transferential Poetics presents a method for bringing theories of affect to the study of poetics. Informed by the thinking of Silvan Tomkins, Melanie Klein, and Wilfred Bion, it offers new interpretations of the poetics of four major American artists: Edgar Allan Poe, Henry James, Gertrude Stein, and Andy Warhol. The author emphasizes the close, reflexive attention each of these artists pays to the transfer of feeling between text and reader, or composition and audience— their transferential poetics. The book’s historical route from Poe to Warhol culminates in television, a technology and cultural form that makes affect distinctly available to perception. …

Geochemistry Of Mineral Dust In The Mcmurdo Dry Valleys Region, Antarctica, Kelly M. Deuerling, Ethan Baxter, Jeremy Inglis, William Berry Lyons

Geography and Geology Faculty Proceedings & Presentations

The transport and deposition of windblown materials are major processes in the ice-free areas of polar regions. The deposition of aeolian material provides connectivity within the ecosystems of these regions and is integral in understanding geochemical balances and exchanges between landscape units. We have analyzed materials deposited on glacier and permanent lake-ice surfaces as well as geomorphological features formed by aeolian processes in the largest ice-free area in Antarctica, the McMurdo Dry Valleys (~78 °S) in order to determine the source of this sediment. This presentation will focus on the materials collected from the glacier and lake surfaces. The bulk …


Poly-3-Hexylthiophene Nanorods As A Donor For Organic Photovoltaics, Dharmesh Patel Dec 2014

Poly-3-Hexylthiophene Nanorods As A Donor For Organic Photovoltaics, Dharmesh Patel

Mahurin Honors College Capstone Experience/Thesis Projects

Poly-3-hexylthiophene functionalized silsesquioxane nanorods (P3HT-NRs) were prepared by direct hydrolysis and condensation of P3HT-silane precursor using the modified Stöber method. The silane precursor was stirred in a mixture of two solvents in the presence of a base under room temperature for three different reaction times. The size, shape, and morphology of these novel nanostructures were visualized using the transmission electron microscope (TEM) and scanning electron microscope (SEM). The composition of the P3HT-NRs was confirmed by FTIR and its silane by proton NMR. Future work will focus on evaluating photovoltaic performance of these nanorods as a donor for organic photovoltaics.

Anatomy and Regenerative Biology Faculty Publications

Xenopus laevis eggs are used as a biological model system for studying fertilization and early embryonic development in vertebrates. Most methods used for their molecular analysis require elaborate sample preparation including separate protocols for the water soluble and lipid components. In this study, laser ablation electrospray ionization (LAESI), an ambient ionization technique, was used for direct mass spectrometric analysis of X. laevis eggs and early stage embryos up to five cleavage cycles. Single unfertilized and fertilized eggs, their animal and vegetal poles, and embryos through the 32-cell stage were analyzed. Fifty two small metabolite ions, including glutathione, GABA and amino …


Kaczmarz Iterative Projection And Nonuniform Sampling With Complexity Estimates, Tim Wallace, Ali Safak Sekmen Dec 2014

Kaczmarz Iterative Projection And Nonuniform Sampling With Complexity Estimates, Tim Wallace, Ali Safak Sekmen

Computer Science Faculty Research

Kaczmarz’s alternating projection method has been widely used for solving mostly over-determined linear system of equations Ax = b in various fields of engineering, medical imaging, and computational science. Because of its simple iterative nature with light computation, this method was successfully applied in computerized tomography. Since tomography generates a matrix A with highly coherent rows, randomized Kaczmarz algorithm is expected to provide faster convergence as it picks a row for each iteration at random, based on a certain probability distribution. Since Kaczmarz’s method is a subspace projection method, the convergence rate for simple Kaczmarz algorithm was developed in …

Pharmacology and Nutritional Sciences Faculty Publications

Human ovarian cancer is diagnosed in the late, metastatic stages but the underlying mechanisms remain poorly understood. We report a surprising functional link between CD151-α3β1 integrin complexes and the malignancy of serous-type ovarian cancer. Analyses of clinical specimens indicate that CD151 expression is significantly reduced or diminished in 90% of metastatic lesions, while it remains detectable in 58% of primary tumors. These observations suggest a putative tumor-suppressing role of CD151 in ovarian cancer. Indeed, our analyses show that knocking down CD151 or α3 integrin enhances tumor cell proliferation, growth and ascites production in nude mice. These changes are accompanied by …

Neutral Density Behavior From 45-90 Km Based On Rayleigh Lidar Observations Above Usu, David Barton Dec 2014

Neutral Density Behavior From 45-90 Km Based On Rayleigh Lidar Observations Above Usu, David Barton

Physics Capstone Projects

There are over 900 nights of observations taken by the Rayleigh lidar above Utah State University from 1993 to 2004. The data have been reduced to give absolute temperatures and relative densities in the mesosphere, from 45-90 km (Herron, 2004, 2007). From the 11 years of relative density data an 11-year climatology of mesospheric densities above Logan, Utah has been created. From this climatology I have been able to normalize the 11 years of density data to the following models: the MSISe00 empirical model, the CPC (Climate Prediction Center) reanalysis model, the ERA Interim reanalysis model, and the NASA MERRA …
