Dimethyl Sulfoxide Oxidation Of Primary Alcohols, Carmen Vargas Zenarosa

Masters Theses

Historical

A method of selective oxidation of primary and secondary alcohols to the corresponding aldehydes and ketones has been developed recently, namely the use of dimethyl sulfoxide (DMSO) as the oxidizing agent, either alone or with dicyclohexylcarbodiimide (DCC)¹⁴, acid anhydrides¹, or alkyl chloroformates¹⁰. The negatively polarized oxygen atom of the sulfoxide group in DMSO is ideally situated for a transfer to many electron-deficient substrates. The oxygen of the alcohol coordinates with the sulfur atom of DMSO through its oxygen atom; this is followed by β-elemination of dimethyl sulfide, thereby resulting in oxidation of the …

Man And His Water Resource, Dean F. Peterson

Faculty Honor Lectures

Several preceding honor lectures have dealt with water. The title of a recent one, "Water and Man," by Dr. Sterling Taylor closely resembles the one for this paper. Dr. Taylor's paper dealt primarily with the physical science of water. This one will consider the nature of the use of water by man and the technological and institutional structure related to that use. Thus there should be no serious overlap. My friends in the social sciences may be surprised, too, to find that somehow this lecture has spilled over into their territory. But engineering is the implementation of science and technology. …

The Synthesis Of 4-Spiro-2-Aryloxazolines Of Potential Pharmacological Interest, Paul Waddell Collins

Theses and Dissertations

Numerous and diverse physiological actions are found among 2-oxazoline compounds. No reports of the synthesis or biological testing of 4-spiro-2-aryl-2-oxazolines were found in the literature. On the basis of the known pharmacological activities of certain aza- and diazaspirans, it was felt that 4-spiro-2-aryl-2-oxazolines should possess medicinal activity. In particular, it was reasoned that the combination in a bicyclic spiro structure of the 2-oxazoline ring with rings systems commonly found in synthetic antitussive compounds might result in active antitussive agents.

The aim of this research was the synthesis of a series· of 2-aryl-2-oxazoline-4-spirocyclopentanes and a series of 1'-methyl-2-aryl-2-oxazoline-4-spiro-4’-piperidines. Six members were …

International Journal of Speleology

Four pools were observed in Banners Corner Cave, Russell County, Virginia, over a 28 month period from November 1961 to February 1964. Three of these pools were visibly polluted with sewage which had seeped into the cave from septic tanks located on the hill above. All four of these pools, at one time or another during the study, contained large populations of planarians, Phagocata subterranea Hyman and isopods, Asellus recurvatus Steeves. Physicochemical and microbiological analyses of the pool waters indicated that oxygen tension is a low as 2.8 mg./l. in one pool and that coliforms and other forms of bacteria …

The Construction Of A Multi-Threshold Foil For Fast Flux Measurements, Michael Henry Holkenbrink

Masters Theses

"The construction of a multi-threshold foil for fast neutron flux measurements is investigated. The factors governing the selection of the materials are the energy response of the given reactor, the half-life of the daughter, the prominent gamma ray emitted during decays, the power level of the reactor, the availability of adequate cross section data, and the alloying properties of the composite foil. A ternary system was chosen as a compromise between the difficulty of fabrication and the amount of information gained from one foil. The particular system chosen was In- P- Fe.

The Relationship Of Instructions During Labor And Relaxation, Frances Josephine Hume Lopez

Loma Linda University Electronic Theses, Dissertations & Projects

A causal-comparative study was done in a county hospital using twenty subjects to determine if the ''unprepared" primigravida patient in active labor will experience less pain if given instructions to aid relaxation. It was hypothesized that the "unprepared" primigravida patients receiving continuous nurse attendance plus instructions to aid relaxation by (1) breathing techniques, and (2) body positions would show less evidences of pain, tension and anxiety during the first and second stages of labor than the group of patients which received only the continuous nurse attendance.

Two devices, (1) a structured observation, (2) a questionnaire with fixed-alternative questions, were used …

The Role Of Thiamine Pyrophosphate In Regulating The Level Of Gamma-Aminobutyric Acid In The Central Nervous System, Bryant L. Adams

Theses and Dissertations

The level of gamma-aminobutyric acid in the brains of white rats suffering from thiamine deficiency symptoms resulting from pyrithiamine or oxythiamine antagonism of thiamine or from thiamine deprivation was measured. The level of this amino acid was 17.5% lower in the brains of pyrithiamine-treated rats and 20.0% lower in the brains of thiamine-deprived rats than in the control rats. Daily injections of ten times the required amounts of vitamin B6 in rats treated with pyrithiamine or oxythiamine or by thiamine deprivation had no effect on the level of brain gamma-aminobutyric acid or on the psiological behavior of these rats. The …

Synthesis Of Potential Anti-Tumor Agents Related To Ethanolamine. I. Phenoxyacetic Acid Derivatives, Kenneth Wayne Rodarmer

Masters Theses

Introduction

Derivatives of phenoxyacetic acid (PAA), because of their activity as synthetic auxins, have long been of interest in the botanical sciences. PAA itself was noted (29) to have some auxin activity. However, real interest in PAA derivatives awaited the establishment of 2,4-dichlorophenoxyacetic acid (2,4-D) as a powerful, selective herbicide (12). An enormous number of PAA analogs and homologs have been investigated for their potential in the herbicide industry, and the statistical evidence from these investigations has been used as the basis for several interesting and sometimes conflicting theories of auxin mechanisms (17, 26, 23, 27).

Physiological effects of PAA …

A Comparison Of Blood Pressure Readings Taken On Preoperative Patients During Hospital Admission And One And One-Half To Three Hours Later, Susan Lee Woodward

Loma Linda University Electronic Theses, Dissertations & Projects

A "before-after" type experimental study was conducted to find an advantageous time to record baseline blood pressure readings on preoperative patients, which could be referred to following surgery and interpreted as representative of normal for the patients. A review of medical and nursing literature revealed that there is a need to established a blood pressure reading indicative of normal for each patient prior to surgery. Because literature substantiated its acceptance, the ausculatory method of taking indirect arterial blood pressure readings was the technique utilized in this study. Sixty conveniently selected general elective surgical patients, twenty-five to forty-five years of age, …
