The Average Potential Method Of Calculating The Resistance Of Power Substation Grounding Systems., David Lane Garrett Jan 1978

The Average Potential Method Of Calculating The Resistance Of Power Substation Grounding Systems., David Lane Garrett

All ETDs from UAB

This thesis develops equations and techniques for modeling the grounding systems of power substations in detail. Equations are derived for calculating the self resistance of each component of the grounding system and for calculating the mutual resistances between each component of the grounding system. Next, techniques are developed for using these self and mutual resistances to obtain the input resistance of the grounding system. These equations and techniques are incorporated into a digital computer program, the results of which are compared with alternate calculation methods for several test cases.Since each component in the grounding system is modeled separately, the method …

The Microbial Ecology Of Phenol Degradation In Activated Sludge., Louise Snowden Rice Jan 1978

The Microbial Ecology Of Phenol Degradation In Activated Sludge., Louise Snowden Rice

All ETDs from UAB

Phenol. Phenol was discovered in 1834 as a byproduct of the coal gas industry and was first used to deodorize the sewers in England. Subsequently, in 1867, Joseph Lister introduced antiseptic surgery by using 5% phenol to disinfect operating room facilities and wounds (6, 25). Lister’s procedure was successful because 5% phenol causes disruption of the bacterial cell wall and precipitation of proteins. Even lower phenol concentrations can be lethal to bacteria by causing damage to the permeability barrier in the cell wall. A 1% solution has been shown to cause leakage of glutamic acid from Streptococcus faecalis. At lower …

Perhaps no other area of criminology offers the rampancy of opportunity for study as does the female offender. Increasingly, it is noted that crime by females is on the rise, not only in the "traditional” crimes usually associated with females, such as sexual offenses (usually prostitution) and theft, but also in more serious crimes such as homicide, robbery, and aggravated assault.

An Analysis Of The Desirable Components Of Doctoral Programs In Educational Leadership As Determined By A Select Group Of Administrators., Suzanne Whitlock Morse

All ETDs from UAB

The role of the educational leader has undergone tremendous change in the last century. Modern society has placed new demands on the historically set role of the school administrator. The concerns have changed from ones of curriculum and accessibility to areas of accountability and finance. With the influx of these pressures and requirements, it has become mandatory that graduate programs in educational leadership become cognizant of the many new masks that the practitioner must wear.

Essential Competencies Of Teachers Of The Gifted., Charlotte Ann Donaldson Jan 1977

Essential Competencies Of Teachers Of The Gifted., Charlotte Ann Donaldson

All ETDs from UAB

It is the teacher who sets the environment which inspires or destroys self-confidence, encourages or suppresses interests, develops or neglects creativity, stimulates or discourages critical thinking, and facilitates or frustrates achievement. -Joan B. Nelson and Donald L, Cleland.The competence of his teacher is a crucial factor in any child's learning, self-understanding, and social adjustment. Indeed, numerous studies have cited the importance of the teacher's knowledge, skills, and attitudes as the key to effective learning in all elementary and secondary educational programs. This project investigated essential competencies of one small but important segment of the profession—the teacher of the intellectually gifted.

In his classic "7, plus or minus 2" paper, Miller (1956) introduced a term to describe what he thought people do when trying to memorize lists of words or numbers. He suggested that people "chunk" small bits of information into larger sets which bear some internal order or whose members share common characteristics, and in so doing implicitly increase their ability to recall large amounts of the designated information.

The Effect Of Psychological Stress On Complex Task Performance., Mary Christine Rumore

All ETDs from UAB

Many individuals are required, intentionally or inadvertently, to engage in complex behaviors under various degrees of psychological stress. Performance efficiency may vary depending on the individual's level of arousal, and high levels of psychological stress might adversely affect task performance. The pervasiveness and importance of the effects of psychological stress on performance have encouraged investigators to explore the relationship between levels of stress and degree of performance impairment.

Multinuclear Nmr Studies Of Gallium Complexes In Aqueous Solution., Chang Hsing Chang

All ETDs from UAB

Gallium-67 tumor scanning is widely employed in the clinical detection and staging of a broad range of solid tumors and malignant lymphomas. As a basis for understanding the molecular mechanism of gallium localization in tumor cells, the aqueous chemistry of gallium(III) was investigated by nuclear magnetic resonance (NMR) spectroscopy. Specifically, these studies include: characterization under various experimental conditions (pH, concentration, temperature etc.) of gallium citrate complexes, of gallium phosphate complexes, and of gallium complexes with EDTA (ethylenediaminetetraacetate), NTA (nitrilotriacetic acid) and lactate etc. The results of these studies demonstrate that all the agents which inhibit in vitro gallium-67 uptake by …

Corrosion has long been recognized as a problem with synthetic, metallic materials for applications in biological environments. This is one of the main reasons type 316L stainless steel and Ti-6Al-4V ELI-grade alloy have emerged as two of the more widely used metallic biomaterials. In recent years with more and more use of metallic implants in patients of younger ages, the time interval over which the implants must function has doubled or tripled.

The Use Of Authority By Probation And Parole Officers: Its Effect On Client Recidivism., Millard Earl Moon Jan 1977

The Use Of Authority By Probation And Parole Officers: Its Effect On Client Recidivism., Millard Earl Moon

All ETDs from UAB

Probation and parole agencies are relatively new additions to the criminal justice system. Although the concept of providing for a mitigation of punishment for certain classes of offenders seems to have existed since the early beginnings of the Anglo-Saxon judicial system as well as under the laws of earlier civilizations, these provisions for the avoidance of severe punishment appear to have been based on very different considerations than those which ideally affect decisions in probation and parole cases today.

Nmr Linebroadening And Contact Shift Studies Of Transition Metal Complexes In Nonaqueous Solvents., Marvin Eugene Harris Jr

All ETDs from UAB

Proton nmr linebroadening studies of dimethylsulfoxide (DMSO) +3 in tris (ethylenediamine) chromium(III) (Cr(en)3 +3)-DMSO solutions were conducted between 20° and 90°C. The resulting data were interpreted using the Swift-Connick relationships. The dominant contribution to linebroadening in the temperature range of 20° - 50°C was a second - coordination sphere exchange process. Above 70°C, the dominant process was a mixture of first coordination sphere exchange process of partially +3 dissociated Cr(en) 3+3 and second coordination sphere T2m-1 relaxation. The kinetic parameters for the first and second coordination sphere processes are ΔΗ≠0 = 24 kcal/mol, k1 = 24 sec-1 and ΔΗ≠…
