Effects Of Acid Mine Drainage On Limnological Conditions And Fish Assemblages In The Cumberland Plateau Region Of The North Chickamauga Creek System, Tennessee, Jennifer Copeland Backer Dec 2002

Effects Of Acid Mine Drainage On Limnological Conditions And Fish Assemblages In The Cumberland Plateau Region Of The North Chickamauga Creek System, Tennessee, Jennifer Copeland Backer

Masters Theses and Doctoral Dissertations

Acid mine drainage (AMD) is the primary water pollution problem in Appalachian streams. The Cumberland Plateau (Southwestern Appalachians ecoregion) portion of North Chickamauga Creek (NCC), a fourth-order tributary to the Tennessee River (Tennessee), has been impacted by decades of AMD from active and abandoned coal mines. I assessed stream characteristics at 19 sites in the Cumberland Plateau region of the NCC system; these data were used to create a GIS database. Limnological conditions and fish assemblage attributes were compared between AMD-impacted and reference sites. Relationships were examined among water quality, habitat, and fish assemblage variables. Stream pH averaged lower at …

Effect Of Riparian Land Use On The Biotic Integrity Of Fish Assemblages In Black Creek, Chattanooga, Tennessee, Jerri Leigh Phillips Dec 2002

Effect Of Riparian Land Use On The Biotic Integrity Of Fish Assemblages In Black Creek, Chattanooga, Tennessee, Jerri Leigh Phillips

Masters Theses and Doctoral Dissertations

Black Creek is a third-order Ridge and Valley stream (Tennessee River drainage) in Chattanooga, Tennessee. Most ofBlack Creek's watershed is forested (ca. 71% in 1991 ). However, increasing urban development, particularly along the riparian landscapes, could impact the stream's ecological health. I assessed fish assemblages (biotic integrity), water quality, instream habitat, and riparian land-use features at eight sites in Black Creek, May-June 2000. Water quality conditions (temperature, dissolved oxygen, pH, conductivity) were favorable for stream fishes, but some level of habitat degradation (bank erosion, sedimentation, loss of riparian vegetation) was observed at all sites. Electrofishing samples yielded a total of29 …

Different Types Of Welfare States? A Methodological Deconstruction Of Comparative Research, Rebecca A. Van Voorhis Dec 2002

Different Types Of Welfare States? A Methodological Deconstruction Of Comparative Research, Rebecca A. Van Voorhis

The Journal of Sociology & Social Welfare

Research on modern welfare states has been strongly influenced by the theory that they develop according to patterns, which form distinct regimes liberal, corporatist, and social democratic. These regimes are characterized by several key variables, among which the decommodification of labor is heavily weighted. This article examines the operational assumptions, measures, and calculations used in the most widely cited empirical study around which distinct regime theory has developed over the last decade. The findings reveal critical methodological weaknesses in the conceptualization and quantification of decommodification measures, which form the empirical cornerstone of distinct regime theory.

"For Their Own Good?": Sex Work, Social Control And Social Workers, A Historical Perspective, Stéphanie Wahab Dec 2002

"For Their Own Good?": Sex Work, Social Control And Social Workers, A Historical Perspective, Stéphanie Wahab

The Journal of Sociology & Social Welfare

This article provides an overview of the social responses to prostitution since the mid 1800s and how the responses of social workers have been shaped by shifting social contexts. Understanding the complex interplay of these forces is key to mapping out the divergent social work practice approaches with sex workers and their influence over time. The article presents three main constructs which have influenced social work responses to sex work; 1) the notion that women needed to be protected for their own good, 2) competing class values and, 3) social control.

From Social Work To Human Services, David Stoesz Dec 2002

From Social Work To Human Services, David Stoesz

The Journal of Sociology & Social Welfare

Social work has forfeited its professional mandate and should be replaced by "human services." In three traditional areas of responsibility-child welfare, public welfare, and mental health-social work has failed to meet its societal obligation. Meanwhile the profession has used postmodern thought to justify a focus on internal constituency groups. A template for professional education in human services is proposed.

Growth Equilibrium Modeling Of Urban Sprawl On Agricultural Lands In West Virginia, Yohannes G. Hailu Dec 2002

Growth Equilibrium Modeling Of Urban Sprawl On Agricultural Lands In West Virginia, Yohannes G. Hailu

Graduate Theses, Dissertations, and Problem Reports (ETD)

With dynamic economic and social changes, increasing pressure is exerted on natural resources management. Agricultural land resources particularly face growing pressure of conversion to non-agricultural uses from population and development demands for land. The continual conversion of agricultural land may have implications in terms of the loss of prime farmland, irreversible landscape changes, deteriorating environmental quality, and interference with rural lifestyles. This study models urban sprawl on agricultural land in a growth equilibrium modeling approach where the population-employment simultaneous equations system is estimated using two-stages-least-squares while changes in agricultural land is estimated using OLS on West Virginia data. Results of …

Chemical And Physical Properties Of Acid Mine Drainage Floc, Catherine M. Bohan Dec 2002

Chemical And Physical Properties Of Acid Mine Drainage Floc, Catherine M. Bohan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Acid mine drainage is a serious environmental concern in many regions worldwide, but especially in coal and metal mining regions. These acid drainages are often treated with chemicals to raise the pH of the water and to cause neutralization and precipitation of metals. As neutralization occurs, a looser gelatinous material called "floc" is produced. The effects of neutralizing chemical, pH, sulfate to iron molar ratio, and solids concentration on floc settling properties were determined in synthetic acid mine drainage. Sulfate was the important factor affecting floc physicochemical properties, increasing settling times from 25-125% and decreasing settling rates from 24-63%. Neutralization …

Thermodynamic Effects Of Phospholamban On Ca-Atpase Kinetics, Patrick L. Apopa Dec 2002

Thermodynamic Effects Of Phospholamban On Ca-Atpase Kinetics, Patrick L. Apopa

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Ca-ATPase of sarcoplasmic reticulum removes cytosolic calcium to promote muscle relaxation. In the heart, the Ca-ATPase is regulated by phospholamban, which inhibits the Ca-ATPase by decreasing Ca-ATPase calcium sensitivity. However, the kinetic and thermodynamic mechanisms of inhibition are not understood. The purpose of this research was to test the hypothesis that phospholamban regulates Ca-ATPase kinetics by increasing Ca-ATPase activation energy. The baculovirus-insect cell expression system was used to produce samples containing Ca-ATPase alone or Ca-ATPase with phospholamban. The temperature-dependence of Ca-ATPase activity and catalytic site density was measured in the absence and presence of phospholamban at sub-saturating calcium and …

College of Polymer Science and Polymer Engineering

Electrospun nanofibers have applications in the areas of filtration, composites; biomaterials, and electronics. Controlling the surface properties of these nanofibers is important for many applications. Nanofibers can also be used as unique substrates for observing the growth of deposited films and creating nanoscale structures. In this work, electrospun poly(meta-phenylene isophthalamide) (MPD-I) nanofibers were used as substrates for creating nanoscale structures out of carbon-based materials and metals. MPD-I was used because it can be electrospun into nanofibers with diameters smaller than 10 nm and it has good thermal stability. MPD-I nanofibers were coated with carbon, copper, and aluminum using plasma enhanced …

Wave Packet Spreading: Temperature And Squeezing Effects With Applications To Quantum Measurement And Decoherence, G. W. Ford, R. F. O'Connell Dec 2002

Wave Packet Spreading: Temperature And Squeezing Effects With Applications To Quantum Measurement And Decoherence, G. W. Ford, R. F. O'Connell

Faculty Publications

A localized free particle is represented by a wave packet and its motion is discussed in most quantum mechanics textbooks. Implicit in these discussions is the assumption of zero temperature. We discuss how the effects of finite temperature and squeezing can be incorporated in an elementary manner. The results show how the introduction of simple tools and ideas can bring the reader into contact with topics at the frontiers of research in quantum mechanics. We discuss the standard quantum limit, which is of interest in the measurement of small forces, and decoherence of a mixed ("Schrödinger cat") state, which has …

The Effect Of Convection On Disorder In Primary Cellular And Dendritic Arrays, R. Trivedi, P. Mazumder, Surendra N. Tewari Dec 2002

The Effect Of Convection On Disorder In Primary Cellular And Dendritic Arrays, R. Trivedi, P. Mazumder, Surendra N. Tewari

Chemical & Biomedical Engineering Faculty Publications

Directional solidification studies have been carried out to characterize the spatial disorder in the arrays of cells and dendrites. Different factors that cause array disorder are investigated experimentally and analyzed numerically. In addition to the disorder resulting from the fundamental selection of a range of primary spacings under given experimental conditions, a significant variation in primary spacings is shown to occur in bulk samples due to convection effects, especially at low growth velocities. The effect of convection on array disorder is examined through directional solidification studies in two different alloy systems, Pb-Sn and Al-Cu. A detailed analysis of the spacing …

Normal Forms For Two-Inputs Nonlinear Control Systems, Issa Amadou Tall, Witold Respondek Dec 2002

Normal Forms For Two-Inputs Nonlinear Control Systems, Issa Amadou Tall, Witold Respondek

Miscellaneous (presentations, translations, interviews, etc)

We study the feedback group action on two-inputs non-linear control systems. We follow an approach proposed by Kang and Krener which consists of analyzing the system and the feedback group step by step. We construct a normal form which generalizes that obtained in the single-input case. We also give homogeneous m-invariants of the action of the group of homogeneous transformations on the homogeneous systems of the same degree. We illustrate our results by analyzing the normal form and invariants of homogeneous systems of degree two.
