Inhibition Of The Aminopeptidase From Aeromonas Proteolytica By Aliphatic Alcohols. Characterization Of The Hydrophobic Substrate Recognition Site, Leila Ustynyuk, Brian Bennett, Tanya Edwards, Richard C. Holz

Physics Faculty Research and Publications

Seven aliphatic and two aromatic alcohols were tested as reporters of the substrate selectivity of the aminopeptidase from Aeromonas proteolytica (AAP). This series of alcohols was chosen to systematically probe the effect of carbon chain length, steric bulk, and inhibitor shape on the inhibition of AAP. Initially, however, the question of whether AAP is denatured in the presence of aliphatic alcohols was addressed. On the basis of circular dichroism (CD), electronic absorption, and fluorescence spectra, the secondary structure of AAP, with and without added aliphatic alcohols, was unchanged. These data clearly indicate that AAP is not denatured in aliphatic alcohols, …

The Middle East In World Affairs Understanding Iran's Changing Transnational And International Role, Marla Renfro

Graduate Program in International Studies Theses & Dissertations

In 1979, the Islamic Republic of Iran emerged on the international stage and began to establish itself as a participant in global terrorism. Throughout the period 1979-96, officials linked numerous terrorist actions and operations to Iran; this link could have involve Iran's direct sponsorship or indirect involvement, such as by providing monetary support to operatives. In order to develop strategies to prevent or minimize the threat of terrorist attack, Iran's role in global terrorism must be assessed.

The purpose of this work is threefold: to demonstrate the role taken by Iran in global terrorism from 1979 to 1996, to explain …

Addition Of Chelated Trivalent Cations To Solutions Of The Polymer Sodium Carboxymethylcellulose (Cmc), Deborah Hawkins

Theses

This study was comprised of two related projects: a viscosity variability study and a trivalent cation study. For the first study, the dependence of viscosity of solutions of the polymer sodium carboxymethylcellulose (CMC) on temperature was quantitatively determined so that the viscosity measurements from four sets of viscosity versus age of solution data could be normalized. The four sets of age of solution data were obtained for two solutions containing Al cation and for two solutions containing Mg cation. The temperature normalization procedure proved viable. Factoring out the variability due to temperature led to a decrease in overall variability of …

Trip Generation Rates For Consolidated Schools In West Virginia, Amy Marie Balmer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Currently, there are no trip generation rates for consolidated schools in West Virginia. A consolidated school is a public school that formed from the consolidation of other schools of the same type or a county-wide school. Because West Virginia is rural in nature and declining school-age population, the trip rates for consolidated schools would tend to be different than the national averages for traditional schools.;This research developed trip rates specific to consolidated high, middle, and elementary schools in West Virginia. In total, sixteen different schools in West Virginia were studied. Of the sixteen sites studied, seven were high schools, two …

Simulation Of Packed Column Jigging, Qiang Dai

Graduate Theses, Dissertations, and Problem Reports (ETD)

Packed column jig has been demonstrated a number of promising results in processing iron ore, coal, chromite and other finely disseminated particulate materials. The packing materials in the jig divide the column into a large number of virtual cells. Each cell performs the similar separation action. A model about the movement of a particle in the packed column jig was derived to interpret the separation mechanism of particles in the virtual cell. A computer program was developed to simulate the particle movement in the jig based on the derived model, which can simulate the packed column jigging with different jig …

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study describes the development of a cultural needs questionnaire intended to get a profile of foreign students' awareness of American culture. Specifically, the original questionnaire was designed to assess the level of awareness that English as a Second Language (ESL) students have of three aspects of American culture: family, gender roles, and education. The purpose of the development of student profiles resulting from this questionnaire was to offer one source of feedback to ESL teachers concerning these particularly relevant areas in which newly arrived students may be culturally confused. The piloting of the questionnaire revealed several problems inherent in …

Meaning And Measurement: Reconceptualizing Measures Of The Division Of Household Labor, Joan E. Twiggs, Julia Mcquillan, Myra Marx Feree

Department of Sociology: Faculty Publications

This article argues that task-specific measures of the division of household labor form a gender hierarchy that reflects dimensions of meaning in the organization of household work. We contrast these measures to the commonly used time-share and Likert scale measures, which assume all tasks are interchangeable. Using Guttman scaling, we test the unidimensionality of this task hierarchy. Using odds ratios, we measure relationships between specific tasks, and using logistic regression, we see differences in correlates of husbands’ participation by task and interrelationships among tasks that persist, controlling for gender ideology and socioeconomic factors. This work should encourage development of measures …

Development And Testing Of Improved Spectral Unmixing Techniques, Daisei Konno

Theses

The tradeoff between spatial and spectral resolution gives rise to a finite ground sample size, which produces data with spectrally mixed pixels in a multispectral and hyperspectral systems. Assuming the mixed pixel to be a linear combination of pure spectra known as endmembers, the fractional abundance of the endmembers can be calculated by linear spectral unmixing. Constraints may be placed to force the unmixed fractions to behave realistically. There are also different methods of selecting these endmember spectra, including scene derived and laboratory measured spectra. The stepwise unmixing uses an iterative regression technique to select the optimal endmembers on a …

Unconstrained Instantaneous Center Integration (Ici) Algorithms, Nathan Eggleton

Theses

This paper presents several unique "instantaneous center integration" (ICI) algorithms for use in studying unconstrained vehicle motion using computer simulations and animations. Specifically, these algorithms are most appropriate for the case when high angular rates are present, such as would occur during tight cornering and/or possibly during an accident. The three ICI algorithms presented are the "pseudo-exact", first order approximation and the second order approximation. These ICI algorithms are capable of producing valid, accurate, and efficient simulation results, which describe the behavior of a vehicle under these conditions. The "pseudo-exact" is the most accurate, yet the most computationally expensive. The …

The present work examines the role of surfactants in inkjet printing. One of the most important properties of inkjet ink is surface tension, and surfactants are used in ink to control this property. Specifically studied in this investigation are different concentrations of the surfactants ethylene glycol dimethacrylate and sodium lauryl sulfate. Surfactants have been ejected using a piezo inkjet printhead, and the …

Smart Decisions, Beatriz Gomez

Theses

It is very often that parents and educators find themselves running out of words when it comes to explaining a sensitive topic to a child. Such topics include but are not limited to sex, abortion, adoption, pregnancy, divorce, drugs, and disease. A computer based game has been designed to help parents and educators address such sensitive topics. This software package consists of a series of two dimensional animations. All of the animations belong to the same story, which as it progress, gives the player the opportunity to make diverse decisions. Each decision leads the player through a different path, hence …

Surface -Enhanced Raman Spectroscopic Studies Of Organonitriles On Copper Colloids, Candace Mikki Coyle

Graduate Theses, Dissertations, and Problem Reports (ETD)

Dramatic differences are observed between the surface-enhanced Raman spectra (SERS) of organonitriles mixed with copper colloids, the Raman of the free parent molecules, and the SERS for adsorption on a gold colloid. Specifically, nu(C≡N) is missing in the SER spectra involving the copper colloid. The data are adequately explained by a transition metal assisted borohydride reduction of the cyano group to an amino group. SER spectra of the reduction products of the organonitriles in the presence of copper colloids are identical within experimental error. The nu(C≡N) signal was observed when a gold colloid was prepared by borohydride reduction, thereby indicating …

Automatic Selection Of Optimal Window Size And Shape For Texture Analysis, Joseph Edmund Glotfelty

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis is a theoretical and empirical examination of the relationship between texture and scale, and its effects on image classification. This study involved creating a model that automatically selected windows of optimal size according to the location of a pixel within a land cover region and the texture of the surrounding pixels. Large windows were used to get a representative sample of within-class variability in the interior of these regions. Smaller windows were used near the boundaries of land cover regions in order to reduce "edge effect" errors due to between-class variability. This program was tested using a Maximum …

Identifying Structural Differences In Mixed Mesophytic And Northern Hardwood Forests On The Monongahela National Forest Using Remote Sensing Data, John Richard Bender Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis is a study of field data and remotely sensed data to evaluate the structural diversity, texture, spectral and spatial differences between forest stands of three age classes (50--69, 70--89, and >90 years) in the Cheat District on the Monongahela National Forest. The structural diversity was determined with foliage-height profiles for 48 stands ranging from 52 to 148 years old. Structural diversity was highest in the 70--89 and >90 year old stands and lowest in the 50--69 year old stands. The structural characteristics of the 70--89 and >90 year old stands were characterized by greater numbers of larger trees, …

Federal Highway Spending And Economic Growth In Appalachia, James Herbert Noonan

Rf Isolation Using Power Islands In Dc Power Bus Design, Jun Fan, Yong Ren, Juan Chen, David M. Hockanson, Hao Shi, James L. Drewniak, Todd H. Hubing, Thomas Van Doren, Richard E. Dubroff

Electrical and Computer Engineering Faculty Research & Creative Works

Power island structures are often employed for minimizing the propagation of high-frequency noise on DC power buses. The rationale is based on introducing a series impedance in the power plane to provide isolation of a noise source from the rest of the PCB design. The power island concept is investigated herein experimentally, to determine its noise mitigation attributes and limitations. A modeling approach that is suitable for arbitrary PCB island geometries including lumped SMT decoupling capacitors is also presented. The modeling and measurements indicate that island structures can achieve some degree of isolation under certain conditions.
