Dialogues In Light And Temperature, Stephen Althouse

Theses and Dissertations

The work illustrated and discussed in this paper was exhibited in the Anderson Gallery, Virginia Commonwealth University, November, 1974, as my graduate show. Presented here is a written explanation of the work contained in that show.

Sexual Adjustment After Myocardial Infarction, Brenda Hove Long

Theses and Dissertations

"Cardiovascular diseases claim more American lives than all other causes of death combined,”¹ as stated in the American Heart Association's Heart Facts 1975. In 1972, it was estimated that 1,036,560 individuals died of cardiovascular disease; 683,100 of these were attributable to acute myocardial infarction.² In addition, an estimated 28,420,000 Americans have some type of cardiovascular disease at a cost of $20 billion annually.³ The figures ”bring home" a stalking reality; cardiovascular disease is epidemic in this country, the incidence and ramifications of which make it an ever-present threat to all Americans. The greatest threat is heart attack, …

Incorporation Of Phosphoproteins And Phenol-Bound Proteins Into The Cuticle Of Periplaneta Americana, Joseph Atchison Florence Iv

Theses and Dissertations

The incorporation of phosphoproteins and phenol-bound proteins into the cuticle of Periplaneta americana was analyzed. Radioactive monosodium phosphate was injected into newly ecdysed cockroaches. Incorporation into haemolymph proteins as well as tanned cuticle was observed. Phosphoproteins were observed to be combined with the cuticle to a greater extent than monosodium phosphate. This suggests that phosphate is being incorporated into the cuticle more readily than monosodium phosphate. The relevance of these observations is discussed in light of phosphate being a possible crosslinking agent between chitin and cuticle protein.

Binding of dopamine metabolites to cuticle proteins was investigated. Specific metabolites studied were …

The Effects Of Chronic Anaerobic Infection On Atherosclerosis In Rabbits, Janet Smitheran Bissell

Theses and Dissertations

Arterial disease is virtually a universal entity in man. Some cultures, such as the African Bantus have very little in the way of vascular lesions, while in the United States and other industrialized nations atherosclerosis affects a large segment of the population. With this in mind it is not hard to understand why ischemia, or arteriosclerotic heart disease, is second only to cardiovascular diseases in general as the major cause of death in the United States (4, 42).

Ruffer (112) noted the presence of arterial lesions in Egyptian mummies dating back 3,400 years. The presence of atherosclerotic lesions has also …

A Spectrophotofluorometric Analysis Of Serum Vitamin A Levels In A Defined Population, James Ronald Schroeder

Theses and Dissertations

The objectives of this thesis were to examine serum vitamin A levels in two defined populations. The method of analysis was a spectrophotofluorometric technique with a correction formula to account for interfering fluorescence from an identified carotenoid phytofluene (37).

The first population were infants at time of delivery. Infants were divided into two groups depending upon length of gestation. A premature group was identified as having a length of gestation of less than 36 weeks. Term infants were defined as 36 weeks or greater. The mean value of serum vitamin A of eight premature infants was 10.5 μg/100ml (S.E.M.+.78). The …

The Influence Of Population Knowledge And Concern On Acceptable Family Sizes And Expected Family Size, Nancy Ross Hugo

Theses and Dissertations

This study focused on the influence of population knowledge and population concern on acceptable family sizes and expected family size. Analysis of the responses of 212 students in Introductory Sociology classes to a questionnaire survey revealed that the greater the student's population knowledge, the greater the degree of concern over population growth. Furthermore, the study revealed a stronger relationship between general knowledge of population processes and population concern than between specific knowledge of population sizes and growth rates and population concern.

Analysis of the relationship between population concern and acceptable family sizes revealed that the greater the degree of concern …

Synthesis Of Tcne And Tcnq Derivatives And The Preparation Of Conducting Polymers, Michael L. Runge

Theses and Dissertations

Tetracyanoethylene and tetracyanoquinodimethane were reacted with various N,N-dimethyl-a, w-alkyldiamines to produce TCNE and TCNQ diamino and monoamino derivatives. NMR and ir spectra of the monoamino derivatives, 1-(N,N-dimethyl-a,w-alkyldiamino)-1,2,2-tricyanoethylenes and 7-(N,N-dimethyl-a,w-alkyldiamino)-7,8,8-tricyanoquinodimethans, indicated that these compounds exhibited strong nitrogen-hydrogen-nitrogen intramolecular hydrogen bonding. This phenomenon was corroborated by molecular weight and preliminary x-ray analyses.

The 1,1-bis(N,N-dimethyl-a,w-alkyldiamino)-2,2-dicyanoethylene and 7,7-bis(N,N-dimethyl-a,m-alkyldiamino)-8,8-dicyanoquinodimethan derivatives were polymerized with a,m-alkyldibromides containing two to six methylene groups to produce the corresponding ionene polymers. Viscosity measurements of the polymers indicated that the TCNE copolymers were generally of higher molecular weight than the corresponding TCNQ copolymers.

The two polymer series were treated with lithium …

Prostaglandin Synthesis In The Feline Adrenal Cortex, Suzanne Gale Laychock

Theses and Dissertations

Studies were carried out on the feline adrenal gland to ascertain the role of prostaglandins in the mechanism of action of ACTH. Using tritiated arachidonic acid as a prostaglandin (PG) precursor , it was demonstrated by column and thin layer chromatography techniques that isolated trypsinized adrenocortical cells possess an active PG synthetase capable of synthesizing radiolabeled PGE, PGF, and PGA/B-like substances. Concentrations of ACTH (125 - 250 _μU) which stimulate steroidogenesis enhanced the conversion of radiolabeled arachidonic acid to PGE, PGF and the PGA/B products extracted from cortical cells and incubation media.

PG biosynthesis by isolated cortical cells was …
