An Investigation Of The Dynamic Response Of The Activated Sludge Process, Tin-Bai Pan Dec 1980

An Investigation Of The Dynamic Response Of The Activated Sludge Process, Tin-Bai Pan

Dissertations

A new mathematical model, derived from first principles of mass balance, is proposed for describing the mass transfer response of an activated sludge aeration tank in terms of a fluidized bed. The operational data to verify the proposed model were taken from an existing conventional wastewater treatment plant and a bench scale pilot plant.

The mass transfer rate, (KdAs), was presented by an empirical dimensionless group function as follows:

((KdAs)Dp/Dv) = fAc (uDp/ν)a ((ν/Dν)(MLSS))b

Or

Sh = f(Ac/As ) …


An Analysis Of Cadmium And Lead Uptake In Hydroponically Grown Corn Seedlings, Julie Jones Medlin Dec 1980

An Analysis Of Cadmium And Lead Uptake In Hydroponically Grown Corn Seedlings, Julie Jones Medlin

Dissertations

The purpose of this study was to analyze selected growth parameters of hydroponically grown corn seedlings (Zea mays) in relation to the uptake of the heavy metals, lead and cadmium. The corn seedlings were treated with various concentrations of lead and cadmium at different levels of pH, and phosphate and ferric ion concentrations. Root and shoot lengths were measured before and after heavy metal treatment to determine the relative growth in the different treatment solutions. Wet and dry weights were also obtained. The plant material was digested with nitric and perchloric acids in preparation for analysis for heavy metal content …


A Limnological Investigation Of A Tropical Fresh-Water Ecosystem: The Belize River, Belize, Central America, Victor J. Gonzalez Aug 1980

A Limnological Investigation Of A Tropical Fresh-Water Ecosystem: The Belize River, Belize, Central America, Victor J. Gonzalez

Dissertations

The limnology of the Belize River, from the region of Spanish Lookout to the region of Belize City, was investigated from 1977 through 1979. The investigation was done primarily during the months of May through August, covering the two seasonal changes--wet and dry--that occur in this tropical region. The investigation sought to describe various parameters of the Belize River so as to gain an understanding of this tropical fresh-water ecosystem and to provide basic information needed for the development of management programs.

Water samples were collected from eight stations and analyzed for acidity, alkalinity, carbon dioxide, chloride, sodium chromate, hexavalent …


The Interrelationship Of Leader Self-Actualization And Life Stressors To The Resultant Incidence Of Reported Medical Problems Of Middle Management Educators, John S. Thatcher Aug 1980

The Interrelationship Of Leader Self-Actualization And Life Stressors To The Resultant Incidence Of Reported Medical Problems Of Middle Management Educators, John S. Thatcher

Dissertations

Schools, being a part of the larger social system, have not escaped the increasing pressures evident in our society. The principalship as an important component of the educational process has not enjoyed immunity from this same problem.

Because school principals are individuals, they react differently to life stressors. Some appear to have the ability to handle all stressors without suffering any onset of medical problems. Others appear not to have this immunity and as a result have medical difficulties. Because of this seeming difference and because of a lack of research of this type in education, the relationships between life …


A Study Of Localism In A Regional State University, Raymond E. Alie Aug 1980

A Study Of Localism In A Regional State University, Raymond E. Alie

Dissertations

This study investigated a relationship suggested in the literature between the level of service which academic departments in former teachers' colleges render to the teacher-training function and the local or cosmopolitan role orientation of their faculties. Localism and cosmopolitanism are polar sets of role expectations toward which professors and other professionals might orient. Dimensions of the local-cosmopolitan concept are: level of loyalty to the employing organization, commitment to professional role skills, and the use of an inner or outer reference group.

A scale of local-cosmopolitanism was constructed for this investigation. Validity of the instrument was established by panel judgment and …


Correlation Of Thixotropic Parameters And Related Tests Of Blood From Human Subjects, Walter Fabisiak May 1980

Correlation Of Thixotropic Parameters And Related Tests Of Blood From Human Subjects, Walter Fabisiak

Dissertations

The flow behavior of human blood is an important facet of the circulatory system as it affects all of the organs of the body. The rheological properties of whole blood provide a means of analyzing the flow of red cells and plasma through the microcirculation. A recently observed rheological characteristic of whole human blood is thixotropy, a time-dependent phenomenon. This phenomenon is caused mainly by the redistribution of an aggregated form of erythrocytes, known as rouleaux, and the non-aggregated, single erythrocytes. In order to further define and analyze the thixotropic properties of blood, the Huang model is used to quantitatively …
