Enhanced Renal Sympathetic And Cardiovascular Responses To Substance P In Hypertension, Gregory W. Lindsay

Electronic Theses and Dissertations

Blood pressure, heart rate, and renal sympathetic nerve responses were measured in 9-13 week old male spontaneously hypertensive rats (SHR) and compared to those in age and sex-matched Wistar-Kyoto (WKY) rats following intravenous injection of the neuropeptide substance P (SP), the nicotinic stimulant 1,1-dimethyl-4-phenylpiperazinium (DMPP), and the adrenoceptor stimulant norepinephrine (NE). Charles River Sprague-Dawley (CD) rats were used in some studies to develop methodologies. Measurements were made in control rats and also following sinoaortic denervation, pithing, ganglion blockade, or adrenoceptor blockade. Responses were evaluated in order to determine if ganglion stimulation by SP was enhanced in SHR compared to WKY …

A Molecular Basis For Erythromycin Sensitivity And Resistance In Escherichia Coli, Harold S. Chittum

Electronic Theses and Dissertations

The effect of erythromycin on the 50S ribosomal subunit during cell growth has been extensively investigated. Sucrose density gradient analysis of ribosomes formed in the presence and absence of the drug revealed a 50S specific assembly defect is partially responsible for erythromycin's inhibitory effects on wild type cells. Examination of two erythromycin-resistant mutants of E. coli (N281 and N282) revealed that mutant N281 (L22 mutant) but not N282 (L4 mutant) was assembly defective in the presence of the drug, although only at much higher drug concentrations (300 ug/ml vs. 75 ug/ml for wild type cells). The altered genes from each …

The Relationship Of Right Brain/Left Brain Hemispheric Dimensions Of Cognitive Style Between Teachers And Principals In Northeast Tennessee, Thomas S. Little

Electronic Theses and Dissertations

The Problem of this study was to determine if the cognitive style of elementary school principals affects the principal's evaluation of a teacher when there is a match or mismatch between the principal's and teacher's cognitive style. Using the Productivity Environmental Preference Survey, the dimensions of right brain/left brain hemispheric dimensions of cognitive style were measured for the sample population. The sample population included 40 elementary school principals and 120 elementary school teachers. The 120 teachers were made up of teachers selected by each of the 40 principals as the most effective teachers in the school. The statistical analysis of …

Intuition In Decision-Making, Joanne Horton

Electronic Theses and Dissertations

This was a two-phase study designed to identify intuitive principals and then to determine if there were common elements of their decision making. The Myers-Briggs Type Indicator was used to identify intuitive principals, and then a sampling of these principals were interviewed. The results showed that the principals with the highest preference scores for intuition differed from the principals with lower preference scores in that they came from supportive environments, were more conscious of using and developing their intuition, drew from experience but combined that with a future orientation, and were more comfortable with risk-taking and change. Recommendations included the …

Comparisons were made of the major components of each model. Actual data from the 14 Tennessee public two-year colleges was incorporated …

Unusual Structure Of A Human Middle Repetitive Dna, Duminda D. Ratnasinghe

Electronic Theses and Dissertations

The L2Hs sequences are a polymorphic, interspersed, middle repetitive DNA family unique to human genomes. Genomic fingerprinting indicates that these DNAs vary from one individual to another and between tissues of the same individual. Sequence analysis reveals that they are AT-rich (76%) and contain many unusual sequence arrangements (palindromes, inverted and direct repeats). These sequence properties confer on the L2Hs elements the potential to fold into non-B-form structures, a characteristic of recombination hot spots. To test this hypothesis carbodiimide, osmium tetroxide and S$\sb1$ nuclease were used as single-strand specific probes to study a recombinant plasmid, pN6.4.39, containing a single L2Hs …

Called To Serve : American Nurses Go To War, 1914-1918., Katherine Burger Johnson

Electronic Theses and Dissertations

World War I resulted in the deaths of over 8,500,000 military personnel and in addition, millions of civilians. There were not enough doctors to provide the necessary medical care for the masses of seriously sick and wounded, and other than in Great Britain, there was little in the way of an organized nursing profession in Europe. Over ten thousand American women served overseas as nurses and nurses' aides from 1914 to 1918, caring for soldiers and civilians of diverse nationalities and proving to be a mainstay in the medical treatment provided for victims of "The Great War." Little has been …

Proposed Smoothing Technique To Avoid Numerical Instabilities In A Hydrodynamic Numerical Model, Thomas P. Abraham

Electronic Theses and Dissertations

Despite every effort being made to produce a completely problem-free computational model, no breakthrough has yet been made. When a numerical model is used to solve a real world problem, there is a tendency for the non-physical spurious waves to creep in. If these waves are not checked, they can lead to serious instability problems. Once these waves are removed, the model should be able to simulate physical phenomenon like circulation, separation, flow reversal in the vertical plane, mixing/transport, convection/diffusion, etc.

When a numerical mode] is made to run for a certain period of time, node-to-node oscillations may arise and …

A Study Of The Atomic Number Dependence Of Charmed D Meson Hadroproduction, Eric Matthew Aitala

Electronic Theses and Dissertations

We have investigated the nuclear A dependence for the production of D0 and D+ charmed mesons in 500 GeV/c πN interactions. The data were taken by the E791 collaboration at Fermilab's Tagged Photon spectrometer and partially analyzed on a large UNIX/RISC based computer farm located at the University of Mississippi. The measurement of the A dependence for charmed meson production reveals information about the quark distribution within nucleons, specifically the quark distribution function and the. nuclear cross sections. The study also reveals information on the state of the E791 reconstruction and Monte Carlo simulation.

An Assessment Of Role Ambiguity, Role Conflict, Role Frustration, And Job Satisfaction Of Presidents At Selected Private Four-Year Colleges In The Southeastern United States, Gary W. Juhan

Electronic Theses and Dissertations

Current literature has suggested that the role of the college president has perhaps become too ambiguous, complex and demanding for an individual to perform for an extended period of time. The purpose of the study was to assess the relationship between perceived role ambiguity, role conflict, role frustration and job satisfaction of selected private college presidents in the Southeastern United States. The method of the study was correlational in design. Using a thirty-seven item questionnaire developed by the author, data were collected from 141 college presidents of institutions within the Southern Association of Colleges and Schools. The institutions were private …

The Bluebonnet Brigade: Women And War In Abilene, Texas: 1941-1945, Tracy Mcglothlin Shilcutt

Electronic Theses and Dissertations

Abilene city fathers perceived the onset of World War II as a potential answer to both economic and population growth goals. Citizens cooperated to secure an Army post, and in February 1941, troops commenced training at Camp Barkeley. With more than 50,000 men eventually serving at the camp, soldiers spent both leisure hours and dollars in the city. Abilenians, eager to protect their virtuous culture, recognized the need for wholesome entertainment for hundreds of unattached young men. Abilene leaders sponsored a women's volunteer association, the Bluebonnet Brigade. Bluebonnets provided companionship for the soldiers while helping the community maintain its moral …

Mechanisms Of T Cell-Mediated Macrophage Activation: Role Of Antigen Specific And Antigen Nonspecific Cognate Interactions, Xiang Tao

Electronic Theses and Dissertations

Macrophages play an important role in host antimicrobial immunity and in non-septic inflammatory reactions. Most studies on macrophage activation have focused on the roles of the T cell-produced cytokine, interferon-$\gamma$ (IFN$\gamma)$ and bacterial product, lipopolysaccharide (LPS). T cell-macrophage interaction is a critical step in initiating both specific and nonspecific immune responses to antigenic stimulation. The current study examines the role of cognate T cell-macrophage interaction in activation of macrophage effector functions and induction of macrophage early activation gene expression. Viable resting T$\sb{\rm H}$2 clone cells can activate IFN$\gamma$-primed macrophages to produce reactive nitrogen intermediates (RNI) or express cytostatic activity. The …

Electronic Theses and Dissertations

The purpose of this study was to uncover the feelings and reactions of students and their parents in regard to the nonpromotion experience. Families with children who had been retained at least once in grades one through eight were purposefully selected as units of study from one of four area school systems. A total of 52 family members from 22 family units participated in 46 separate, qualitative interviews. The information collected from the interviews was inductively analyzed. Building upon Schlossberg's theory for human adaptation to transitions, seven factors or coping resources emerged from the data that affected the adaptation of …

Human Lung Mast Cell Tryptase Isozymes: Separation And Examination Of Structural And Functional Differences, Susan S. Little

Electronic Theses and Dissertations

Tryptases are trypsin-like enzymes found in mast cell granules. Although in vivo substrates have not been positively identified, tryptases cleave a limited number of potential physiological substrates in vitro, including high molecular weight kininogen (HMWK) and vasoactive intestinal peptide (VIP). Purified human lung mast cell tryptase (HLT) apparently exists as a tetramer with an M$\sb{\rm r}$ of 135-144 kDa by gel filtration, whereas SDS-PAGE yielded two bands of M$\sb{\rm r}$ 29 Kda and 33 Kda. Tryptases are resistant to inhibition by most natural trypsin inhibitors and display some affinity for heparin. The existence of tryptase isozymes has been implied from …

Probing Protein-Protein Interactions Among Proteins Of A Nonaggregated Fatty Acid Synthetase From Euglena Gracilis Variety Bacillaris, Sande G. Williams

Electronic Theses and Dissertations

Enoyl-acyl carrier protein (ACP) reductase from chloroplast nonaggregated fatty acid synthetase (FAS) of Euglena gracilis variety bacillaris was purified to a single band on a denaturing polyacrylamide gel. The enzyme was partially characterized with respect to substrate specificity, reduced nucleotide requirement, and the effect of ACP and Ca$\sp{++}$ on enzyme activity. Antibodies against the purified protein were raised in hens and isolated from eggs. ACP was purified from Euglena in yields of about 1mg/100g (wet weight) of cells. Antibodies were raised against the purified protein. ACP antibodies inhibited the Euglena chloroplast FAS using Euglena or E. coli ACP as a …

A Theologically-Rooted Order Of Worship For The Pipeline Road Church Of Christ, Jim Mcdoniel

Electronic Theses and Dissertations

When a church does not plan its worship, that worship will typically demonstrate a lack of progression, theme, and appropriate movement. As a result, the assembly will neither adequately edify the saints nor praise God. Yet, many churches do little planning for worship. The Pipeline Road Church of Christ in Hurst, Texas, was one of those churches. Little was done to coordinate the activities of the assemblies before this study.

The Circumplex Model: A Method Of Discovering Church Typologies, Eric Lynnon Cupp

Electronic Theses and Dissertations

This thesis examines the amount of cohesion and the level of adaptability present among members of the Eastern Hills Church of Christ. Given this information, the members of the congregation were asked a single question to gauge their level of satisfaction with the church. The Eastern Hills Church of Christ is a diverse group, comprised from two churches in Athens, Texas, plus many people who have moved in from metropolitan areas. The objective of this project is to empirically test the factors of cohesion and adaptability and to use that information to find the typology of the congregation. The typological …

Old Testament Poems For Vow Fulfillment: A Form-Critical And Theological Study, R. Christopher Heard

Electronic Theses and Dissertations

The most pervasive and enduring contribution of Hermann Gunkel's form­-critical program for psalms studies is the insight that certain types of poems are par­ticularly well suited to certain types of cultic occasions. One such occasion is the fulfillment of a vow, mentioned in eight psalms, one poem outside the book of Psalms and several other contexts. To date, however, a separate category of poems for vow fulfillment has not been widely recognized. The form-critical insight men­tioned above raises the question whether there exists among Hebrew poems a genre of poems for vow fulfillment. The recurrence in the psalms of phrases …
