An Investigation Of The Combined Heat And Mass Transfer Processes In The Drying Of Hygroscopic Porous Media With Two Disparate Length Scales, Thomas Joseph Phillips

Doctoral Dissertations

A mathematical model describing the drying process in a hygroscopic porous medium with two disparate length scales is formulated. The mathematical model is used to identify the important dimensionless parameters appearing in the problem; and, a parametric study is performed to determine the effects of varying these parameters on the drying process. Of particular interest in this study is to apply the model to the drying of large, round hay bales. Therefore a discussion of how the results of the parametric study impact on the efficient use of a hay drier is also presented.

The results from the parametric study …

A Phenomenological Investigation Of Creativity In Person Centered Expressive Therapy, Mukti Khanna

Doctoral Dissertations

The field of creative or expressive arts therapies seeks to harness the power for'creative expression to the process of psychotherapy. Although expressive arts therapies are increasingly being used with a variety of populations, including the elderly, the disabled, intergenerational, and cross-cultural groups, a comprehensive theory of expressive arts therapies has yet to emerge. In addition, there is a paucity of research of what works in such therapies. A comprehensive theory of expressive arts therapies, however, can only emerge from the expressive arts themselves, reflecting the uniqueness of the creative process that is at their foundation. Qualitative research focusing on the …

Effects Of Acidic Precipitation On The Soil Chemistry And Bioavailability Of Aluminum, Manganese, And Copper, Alan Christie Stam

Doctoral Dissertations

The effects of acidic precipitation on the soil solution chemistry and bioavailability of AI, Mn, and Cu in soils from spruce-fir and oak-hickory forests were examined in laboratory, greenhouse, and field studies.

Soil solution concentrations of labile (inorganic) monomeric AI (LMAI) increased with decreasing solution pH and with increasing exchangeable AI and decreasing exchangeable Ca/AI of the soils. Dissolved organic matter decreased with decreasing solution pH and influenced decreases in nonlabile (organic) monomeric AI (NLMAI).

Simulated acidic precipitation increased LMAI concentrations in the laboratory equilibration and greenhouse studies, but not in the field plot studies in oak-hickory and spruce-fir forests. …

Relationship Of Free Fatty Acids And Acid Degree Values To Lipolytic Flavor Of Milk, Susan E. Duncan

Doctoral Dissertations

Free fatty acids were studied in relation to acid degree value (ADV) and rancid flavor (RF) in milk and ADV evaluated as a method for measurement of RF. Selected fatty acids (FA) were blended in milk at .25µmol/ml milk with emulsifier. Recovery of FA was <.63 (C₄-C₈), 1.95-2.33 (C₁₀-C₁₆), 3.24 (C_18:0)» and 4.12µmol/g fat (C_18:1). Significant differences (p<.05) in recovery were found among all groups of FA. Recovery of 5 concentrations (.20, .25, .35, .45, .55 µmol/ml milk) did not differ (p>.05) for C₄ (<.51 µmol/g fat), was proportional to added concentration of Cio with significant differences between low and high concentrations (1.94-4.64 µmol/g fat), and was significantly higher with increasing concentration of C_18:1 (3.91-11.08 µmol/g fat). Fatty acid partitioning into skim (C₄) or fat (C₁₀/ C_18:1), as separated by ADV procedure, was demonstrated …

Incorporating Subsistence Into Hedonic Price And Nutrient Demand Models, Cristanna M. Cook

Doctoral Dissertations

Economic theory concludes that utility from the consumption of goods increases at a decreasing rate. This condition also applies to the characteristics model of consumer choice. However, most applications for food use hedonic price equations and nutrient demand equations that do not account for declining marginal utility. Another problem is that nutrient valuation studies have not considered the level of nutrient adequacy or status. In addition, nutrient consumption models have not accounted for the nutritional status of the consumer when trying to identify the variables that influence nutrient consumption.

Data from the 1977-78 Nationwide Food Consumption Survey were used to …

Ethical Analysis Of Trust In Therapeutic Relationships, Michele A. Carter

Doctoral Dissertations

The problem of this philosophical study was to analyze the concept of trust for its nature, scope, and value, and to apply this analysis to an investigation of trust claims in therapeutic relationships between patients and practitioners. The analysis included semantic, literary, sociological, epistemological, and moral considerations. Classical philosophical texts were examined in order to determine the importance of trust as an instrumental value and as a requirement for morally desirable societies. Contemporary sociological theories regarding the function of trust were examined, as was the relationship of trust to the norm of truthfulness. Contemporary philosophical arguments which claim that trust …

Coparental Conflict, Competition, And Cooperation And Parents' Perceptions Of Their Children's Social-Emotional Well-Being Following Marital Separation, Belinda Belinda Trotter

Doctoral Dissertations

The first purpose of this study was to test a conceptual model that postulated that coparental conflict (disagreements between divorcing spouses over child-rearing issues), competition (triangulation of their children in coparental conflicts), and cooperation (supportive behaviors) are three interrelated but distinct dimensions of the quality of the former spouse relationship (QFSR). The second purpose was to examine the relative, unique direct effects of the three coparental variables on parents' perceptions of their children's social-emotional wellbeing (CSEWB) following marital separation. It was hypothesized that CSEWB is affected negatively by coparental competition and, to a lesser degree, positively by coparental cooperation, but …

Effects Of Prescription Drug Warning Messages On Perceived Risk : An Elaboration Likelihood Approach, Stephen E. Everett

Doctoral Dissertations

Responding to relaxed regulation, pharmaceutical manufacturers recently have instituted direct-to-consumer (DTC) prescription drug-advertising, bypassing the physician. The resulting debate over the propriety of such DTC advertising has centered, in part, on the effects of DTC advertising upon untrained consumers, particularly the effectiveness with which those ads convey risk information to readers/viewers. This study examined relations among several important risk communication variables, within the framework of the Elaboration Likelihood Model of persuasion. How are the complexity of risk information in an advertisement and the reader's prior product ·knowledge related to important "central" responses such as product-relevant thought, perceived risk and attitude …

Air Stripping Of Volatile Organic Compounds From Groundwater: An Evaluation Of A Centrifugal Vapor-Liquid Contactor, Surinder Paul Singh

Doctoral Dissertations

The performance of a centrifugal vapor-liquid contactor equipped with high specific surface area packing (>2000 m²/m³) was evaluated for air stripping of jet fuel components from groundwater. Hydraulic test data indicated that the Sherwood flooding correlation which has been proposed for use in designing centrifugal vapor-liquid contactors overestimates the rotational speeds at which flooding occurs. For the mass transfer of performance, a concept of area of a transfer unit (ATU) was introduced to account for the change in fluid loading with radius of the packing torus. The ATU was found to be a strong function …

The Effect Of Exercise, Diet Restriction And Aging On The Pituitary-Adrenal Axis In The Rat, Madeline Dellwo

Doctoral Dissertations

The effects of calorie restriction and exercise on feed consumption, growth, and the pituitary-adrenal axis were studied in aging male Wistar rats. The study consisted of 4 experimental groups: Sedentary, ad libitum fed controls (A); Sedentary, diet restricted by feeding on alternate days (R); Exercised by swimming on alternate days, ad libitum fed (AE); Exercised by swimming on alternate days, diet restricted by feeding on alternate days (RE).

Training effect was verified by heart weight:body weight ratio. Exercise resulted in a significantly lower body weight, in spite of the fact that exercised animals ate more than the sedentary animals. Body …

An Examination Of Subsistence, Settlement, And Chronology During The Early Woodland Kellogg Phase In The Piedmont Physiographic Province Of The Southeastern United States, William Rowe Bowen

Doctoral Dissertations

The Early Woodland Kellogg Phase of north-central Georgia is known primarily from survey and excavation data collected during the 1930s, 1940s and 1950s. Knowledge and synthesis of the Kellogg Phase was restricted to site specific and cultural historical analysis. Data analysis and interpretation were based on method and theory in vogue at that time. More recent investigations indicate that Kellogg was a much more dynamic and diverse cultural manifestation than originally interpreted.

The purpose of this study is to define subsistence and settlement patterning and refine chronological placement of the Kellogg Phase by reevaluating earlier data in light of contemporary …

A Multivariate Craniometric Analysis Of Secular Change And Variation Among Recent North American Populations, Peer Henning Moore-Jansen

An additional analysis of collection specific cranial variation between two prominent anatomical collections is also undertaken. Both investigations address the question of crania variation in reference to the proper application of craniometric analysis to medico-legal identiciation of racial affiliation in forensic anthropology.

The craniometric data include individual historic specimens and cemetery populations from Canada, Philadelphia and New Orleans. Anatomical specimens are collected from the Hamann-Todd and R. J. Terry collections, and recent forensic cases are obtained from …

The Social Interaction Of Mainstreamed High School Students: An Ethnographic Inquiry, Marge Terhaar-Yonkers

Doctoral Dissertations

This ethnographic study examined the social interaction of mainstreamed and nondisabled learners at McArthur High School. The researcher studied the relationship between social interaction and context and the meanings held by McArthur students and teachers. Participant observation, structured and unstructured interviews, and artifact collection were the methods used to obtain these descriptions. The study was divided into three phases, each focused on a specific component of social interaction: peer interaction, reported standards which shape interaction, and standards negotiated in action, "standards in action." For each of the phases, descriptions were provided and comparisons were made between mainstreamed and nondisabled learners. …

The Effects Of Combinations Of Gum, Starch, And Water On Batters And Microwave-Baked Cakes, Marsha. Mcneil

Doctoral Dissertations

In order to investigate the effects of microwave-baking of cakes, 60 combinations of hydroxypropyI methycellulose (1.8, 2.0, 2.2%, fwb), modified pregelatinized potato starch (3.2, 4.2, 5.2, 6.2% fwb), and deionized water (137.5, 150.0, 162.5, 175.0, 187.5% fwb) were used in a modification of the AACC layer cake formulation. The study was a balanced incomplete block. Batter tests included pH, specific gravity, and viscosity. Cake and crumb tests included weight loss and moisture content. Shrinkage, volume, symmetry, and uniformity also were determined. A modified texture profile analysis was done. Gum level was not significant (p<0.05) for most of the objective measurements. Starch content was a significant factor (p<0.05) for pH, viscosity, and chewiness. Water levels influenced al l of the objective batter and cake tests except weight loss and uniformity.

A lexicon of sensory terms and …

A Bioeconomic Simulation Of Forage-Beef Systems Under Risk Conditions, William D. Mcbride

Doctoral Dissertations

Uncertain forage production and price conditions provide much of the business risk facing Tennessee cattle producers. This study focused on the evaluation of pasture improvement and calving strategies in terms of their biological and economic performance in this complex and uncertain environment.

Eight production alternatives were examined. Included were four forage systems, grass pastures of tall fescue and bermudagrass/tall fescue and each grass pasture renovated with red clover and annual lespedesa legumes. Each forage system was evaluated with spring and fall calving beef herds. A cattle operation in the southwestern portion of Tennessee was used as the unit of analysis. …

The Behavior And Natural History Of The Florida A Red-Bellied Turtle, Pseudemys Nelsoni : An Ethological Study, Matthew Kramer

Doctoral Dissertations

Field work was conducted in 1983-1986 to gather data on social behavior of the Florida red-bellied turtle, Pseudemys nelsoni, by direct, underwater observation (Rock Springs run, Apopka, Florida) and home range analysis using mark-recapture and telemetry techniques (Rock Springs run and Payne's Prairie, Gainesville, Florida). Laboratory observations and experiments were conducted at the University of Tennessee in 1982-1986. A behavior catalog of P. nelsoni was constructed. While not comprehensive, it indicates that the social behavior of this species is complex and adapted for conditions of poor visibility. Conspecific identification probably occurs prior to courtship and other social interactions. Aggressive …

A Theory Of Relative Boundedness And Relative Compactness For Ordinary Differential Operators, Terry G. Anderson

Doctoral Dissertations

In this thesis we develop a perturbation theory for ordinary differential operators. In the following, the differential operator B will be regarded as a perturbation of a (typically) higher-order differential operator L. For certain classes of operators L, we obtain necessary and sufficient conditions for B to be L-bounded or L-compact.

Dermatoglyphic Variation Among Sub-Saharan Africans: $Ba Multivariate Analysis Of Population Structure, David Roehm Hunt

Doctoral Dissertations

It has been previously observed that population structure analysis using dermatoglyphics tends to follow similar patterns formed by other biological features (serology, craniometric, anthropometrics), and reflect relevant linguistic or geographical distributions. But the level of these correlations has not been consistantly identified, causing some debate over the validity of dermatoglyphics as a form of study in human populations. A systematic analysis of a series of populations needs to be made to evaluate how well dermatoglyphic variables generate significant genetic, cultural and geographical relationships dermatoglyphic affinities. between groups, and which features best present these particular population affinities. Using multivariate statistical methods, …

External Costs To The Carter Community From Siting A Municipal Landfill In East Knox County, Tennessee : A Contingent Valuation Analysis, Margaret V. Douglas

Doctoral Dissertations

One of the most intense issues in solid waste management is where to site new landfill disposal facilities. With increasing public concern over the risks from landfills, policymakers are being forced to consider the external costs of landfill disposal. The external costs of siting a landfill in a rural Tennessee community were estimated using the contingent valuation method. A personal interview survey was administered to 150 randomly selected households to determine the community's willingness to pay to avoid having a landfill sited in the area. A regression analysis was also performed to determine the relationship between willingness to pay and …

The Alienation Of Aggressive Children: A Correlational Analysis Among Child And Maternal Measures Of Depression And Behavior, Debra M. Bond

Doctoral Dissertations

The social alienation of aggressive children often leads to the child's experience of isolation, frustration, rejection and/or depression. The aggressive child's experience of depressive symptoms was examined to determine relationships between depressive symptomatology and mother-child interactions. Using a multimethod approach which included self report, parent report and observational measures, child self reported depression was found to be significantly related to mother aversive behavior. Children with lower self reported depression had mothers who were more aversive. In addition, mothers who were more aversive had children who exhibited more aversive as well as more positive behaviors. Thus, the children of highly aversive …
