Anaerobic Biodegradation Of Trichloroethylene With The Addition Of Sugar Using Activated Carbon-Fluidized Beds, Suxan Huang

Dissertations

Anaerobic biodegradation of trichloroethylene (TCE) was carried out in a two-stage granular activated carbon fluidized bed bioreactor. The intermediate products were identified as: dichloroethylene (DCE), vinyl chloride (VC), 1,2-dichloroethane (DCA) and chloroethane (CA). Of the three geometric isomers of DCE, the trans-1,2 dichloroethylene (TDCE) was found to be the most predominant species, The production of DCA suggested a diverted reaction sequence from the conventional sequential reductive dechlorination pathway postulated in the past literature. CA was believed to be a product of VC and/or DCA. The co-substrate glucose was implicated for this reaction specificity. Based on our data and on other's …

Air Stripping Of Volatile Organic Contaminants Using Rotating Disc Contactor, Kai-Ping Hsueh

Dissertations

Previous studies have suggested that the transfer of VOCs to the atmosphere by air stripping may be a convenient and potentially cost-effective method to remove these compounds from the water. A Rotating Disk Contactor (RDC), similarly to other aeration devices, can provide intimate contact between the VOC-bearing water and air. It is believed that under carefully selected operating conditions, the RDC system are more competitive with packed tower than other aeration methods. The objectives of this study were to evaluate the feasibility of using the RDC to strip VOCs from the contaminated water and to develop a mathematical model to …

Permeability And Volume Change Characeristics Of Bentonite-Sand Mixes In A Contaminant Environment, Yuan-Hsun Wu

Dissertations

This research was conducted to study the characteristics of permeability and volume change of bentonite-sand mixes due to contaminants. The soil specimens consisted of clean sand, bentonite, and fly ash. Test liquids included seven diluted organic and inorganic chemicals and a landfill leachate.

Index tests included liquid limit, expansion, cracking, and sedimentation tests. Expansion tests proved to be the most useful for permeability evaluation in a contaminant environment.

The conventional consolidometer permeameter and flexible wall permeameter proved to be not completely satisfactory for testing soft bentonite mixes. A triple ring permeameter was developed to compensate for the limitations of these …

A Comparison Of Minimal-Therapist-Contact Programs In The Treatment Of Chronic Headaches, John Kesselring

Dissertations

The purpose of the study was to compare the relative efficacy and cost-efficiency of two reduced-therapist-contact formats for delivery of a behavioral package to treat chronic headaches. The 8-week treatment was delivered in a group-administered format to one treatment group and in a self-administered format to a second. A waiting-list control group was also included. Treatment components included education about headaches and their precipitants, relaxation training, and cognitive-behavioral stress management techniques. The participants in the study suffered from migraine, mixed, or tension headaches. Eleven subjects were assigned to each of the 3 treatment conditions. At posttreatment subjects in the group-administered …

The Impact Of Type Of Ownership On Mental Health Organizations: The Privatization Alternative, Gary R. Mathews

Dissertations

In recent history most citizens have traditionally considered care of the mentally ill a public service, a government responsibility, and a financial expense best acquitted through taxation. A current topic of debate is whether or not mental health care should continue to be provided primarily in the public realm or instead be provided as a business. A question which must be answered as a part of this debate is: Does type of ownership affect service provision, and if so how? In order to answer this question data from the 1983 Inventory of Mental Health Organizations, a national survey sponsored by …

A Study Of Personality Factors And Music Preference, Involvement, And Use Among Youth, Sheila Ann Smith

Dissertations

The purpose of this study was to determine if a relationship exists between the music preferences, level of music involvement, and music uses among young people and the personality dimensions of internality (introversion), norm-acceptance, and sense of self-realization and psychological integration as measured by the Structural scales of the California Psychological Inventory.

An investigator-developed instrument was used to assess subjects' music preferences, level of music involvement, and uses of music. One hundred and sixty-three females and 137 males attending various southwestern Michigan colleges volunteered to complete both instruments. Subjects ranged in age from 18 to 20 years.

The Medicalization Of Senile Dementia: From "Normality" To “Pathology”, Rosamond Robbert

Dissertations

Once considered an uncommon presenile condition, Alzheimer's disease is today claimed to be one of the major causes of death in older persons. This study examines the process of changing definitions that led to this reconstruction. The method employs both unstructured non-quantitative and structured quantitative content analysis. The data base includes journal articles, media reports, government documents, professional manuals and conference proceedings. Alzheimer's disease is treated as a putative condition and all statements concerning the condition are treated as claims. Focusing specifically on the years 1970 to 1985, we show that cognitive impairment in older persons, once claimed to be …

The Role Of Volition In Exercise Behavior, Mary L. Digangi

Dissertations

Problem. Many theorists have long pondered the ability of human beings to self-determine or to demonstrate volition. Researchers in the human-studies field have been unable to demonstrate empirically the volitional components in human behavior due to the limitations of traditional, scientific methodologies. This study shows how volitional research could be conducted in the context of exercise behavior.

Method. Thirty-five individuals were recruited who wished to increase exercise behavior in their lifestyles. The study ran for 112 consecutive days and was conducted in four phases: baseline, simple volition, volition-plus, and maintenance. In the two volitional conditions, subjects tried to exercise as …

An Assessment Of Effective Fund-Raising Policies Used At Private, Church-Related Undergraduate Colleges, Albin H. Grohar

Dissertations

Problem. Much of what is known concerning fund-raising policies and practices at colleges in the United States is anecdotal. Few empirical studies have focused on any aspect of fund raising. No known empirical study has identified those fund-raising policies that might help church-related colleges to be more effective in generating gift income from private philanthropy. The purpose of this study was to bring to light those fund-raising policies that may be associated with effective fund-raising programs at church-related colleges.

Method. Typically, fund-raising productivity is associated with total funds raised. An alternative way of assessing fund-raising effectiveness is to compare what …

Multiple Role Women And Their Spouses: Variables Effecting Family Functioning, Julie C. Novak Dnsc, Cpnp, Ma, Rn

Dissertations

The purpose of this study was to examine the effect of age, education, perceived child care support, social support, role conflict, coping and marital adjustment on family functioning as experienced by multiple role women and their spouses. The family has long been recognized as the most important contextual influence in human growth and development. Nurses have been working with families for generations, especially in community and mental health nursing. It is only in the last decade, however, that there has been an increasing interest in family research among nurses reflected in a trend away from individual-focused studies and toward a …

The Schools Of The Future Commission Of San Diego City Schools: An Ethnographic Study, Bertha Ousley Pendleton Edd

Dissertations

Ethnographic research methods were used to analyze the culture of a large city commission appointed to make recommendations for the future of the school district. The study focused on the year-long deliberations of a panel of 17 community leaders. The objectives of the study were to (1) describe the culture of the Commission, (2) analyze the action of Commission members, and (3) develop guidelines for conducting successful commission studies. Major research questions that were the focus of the study were inquiries about (a) the social and cultural organization of the Commission, (b) how the Commission developed and proceeded to do …
