The Bromination Of 1,1,1-Ethanetriacetic Acid, John A. Gurney Jul 1958

The Bromination Of 1,1,1-Ethanetriacetic Acid, John A. Gurney

Theses and Dissertations

Essential to the entire field of Organic Chemistry is the nature of the carbon to carbon bond. Our current concepts and guiding principles concerning it are almost solely constructed from aliphatic compounds, certain simple ring species, and aromatic systems. Except for special cases, aliphatic and aromatic types are felt to be mildly strained or free from internal tension while the alicylic small and medium ring compounds are the so-called strained molecules. These strained compounds involve bending back or compression of two of the four carbon bonds from an equilibrium position. Distortions of more complex origin occur in the paracyclophanes and …

The Magnesium-Hydrogen System, J. Frederick Stampfer Jr. Jun 1958

The Magnesium-Hydrogen System, J. Frederick Stampfer Jr.

Chemistry and Chemical Biology ETDs

The motivating factor for this investigation of the magnesium-hydrogen system was the recent interest in the hydride of beryllium. Although beryllium hydride has been prepared by the pyrolysis of di-t-butylberyllium, no evidence for the direct union of beryllium and hydrogen has been reported. It was thought that an examination of the reaction between magnesium and hydrogen and determination of the thermodynamic relations involved might have a bearing on this phenomenon. Also, the properties of magnesium hydride are interesting from an over-all periodic table viewpoint. The hydrides of beryllium and magnesium are usually considered to be intermediary between the saline, or …


The Jurassic Todilto Formation Of New Mexico, Henry O. Ash Jun 1958

The Jurassic Todilto Formation Of New Mexico, Henry O. Ash

Earth and Planetary Sciences ETDs

The Todilto formation of New Mexico is a widespread and distinctive Jurassic unit confined to the northern one-half of the State and adjacent parts of Arizona and Colorado. It consists of a lower Limestone member and an upper Gypsum member. The Gypsum member also contains some limestone. The two members are not coextensive in area. Both are present in the central part of the area in which the formation is found, but the Limestone member extends far beyond the limits of the Gypsum member.

A Problem In Atmospheric Diffusion, Albert C. Giere Jun 1958

A Problem In Atmospheric Diffusion, Albert C. Giere

Physics & Astronomy ETDs

This study concerns the diffusion of atmospheric ozone through a one dimensional region, given certain initial and boundary conditions. As shown in Figure 1 the region is bounded by the planes x= -a and x=b. The plane x=0 divides the region into two parts, Region I and Region II. The solution to this type of problem consists in giving the concentration as a function of the time for any point x in both regions. A general analytic solution is obtained by means of the Laplace transformation using coefficients of diffusion which differ in Regions I and II, but which are …


On The Relation Between The Cosmic Ray Air Shower Spectrum And The Pulse Height Spectrum Of A Large Scintillator, Robert T. Barton Jun 1958

On The Relation Between The Cosmic Ray Air Shower Spectrum And The Pulse Height Spectrum Of A Large Scintillator, Robert T. Barton

Physics & Astronomy ETDs

The purpose of this paper is to study other lateral distribution functions proposed by various authors, to select an alternative to the one used previously, to repeat the calculations of the required quantities using the alternative function, and to comment on the relative merits of the different choices. Since an empirical formula was used in the original work it seemed desirable to use a theoretical relation for comparison if a suitable one were available.

Investigation In The Use Of Infrared Absorption Spectrophotometry, Richard Henry Murcott Jun 1958

Investigation In The Use Of Infrared Absorption Spectrophotometry, Richard Henry Murcott

Honors Theses

Three rather unrelated projects in infrared spectrophotometry were carried out by the writer. First, some effort was expended in trying to find cell windows which were suitably transparent to infrared radiation and yet water insoluable. Secondly, B, the effects of dilution on certain w-lactams was investigated to check for hydrogen bonding effects on their spectra. Thirdly, C, some trial investigations were made using a silver chloride polarizer unit recently acquired for use with the Perkin-Elmer Model 21 spectrophotometer.


Structure Of Ch2, Gordon A. Gallup Jun 1958

Structure Of Ch2, Gordon A. Gallup

Gordon Gallup Publications

Gray has criticized the calculation of the ground state multiplicity of the CH2 fragment by the author. In answer, I would like to make two comments.
1. Regardless of the energies of ionization of a carbon atom, CH2 may be considered as a system composed of two protons, a carbon kernel, and four electrons. The proper amount of configuration interaction should arise naturally and depend on relative energies of orbitals and overlap values. It appears that there is too much configuration interaction in the calculation in reference since the equilibrium angle arrived at is 160° instead of 140° …


A Study Of Methyl Ethyl Ketone And Butanol-2 By Gas-Liquid Partition Chromatography, Ronald John Dubois Jun 1958

A Study Of Methyl Ethyl Ketone And Butanol-2 By Gas-Liquid Partition Chromatography, Ronald John Dubois

Honors Theses

The problem of analysis of commercial and student preparations of butanol-2 from methyl ethyl ketone by gas-liquid partition chromatography is presented. The retention times of butanol-2 and methyl ethyl ketone are determined under varying conditions of temperature, flowrate, carrier gas, column packing and fixed phase concentrations. Optimum conditions are selected for the separation of butanol-2 and methyl ethyl ketone. Several methods are discussed for the quantitative interpretation of the data. The presence of an unknown component in commercial methyl ethyl and ketone and butanol-2 is found and possible identification is discussed. A brief outline of the apparatus is involved and …


Dielectric Constant-Temperature Relationship In Some Chlorinated Phenyl Ethers, Raymond Stuart Martin Jun 1958

Dielectric Constant-Temperature Relationship In Some Chlorinated Phenyl Ethers, Raymond Stuart Martin

Honors Theses

Dielectric liquids play an important role in the transmission, distribution, and use of electrical energy. A liquid is arbitrarily classed as a dielectric if its volume resistivity is 10(10) ohm-centimeters or greater. (An ohm-centimeter is the resistance between opposite faces of one cubic centimeter of the liquid.) Transformers, circuit breakers, cables, and capacitors are among the more common devices using liquid dielectrics. The chief electrical properties which determine the performance of a dielectric liquid are its ability to resist breakdown under electrical stress, its dielectric constant (or specific inductive capacity), and its loss factor - the energy loss per unit …


A Problem Situation Unit In In-Service Education For Graduate Nurses, Bessie E. Irvine Jun 1958

A Problem Situation Unit In In-Service Education For Graduate Nurses, Bessie E. Irvine

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to develop a problem situation unit that could be used for stimulating graduate nurses to assume their responsibility regarding the use of pain and anxiety relieving drugs, namely narcotics, tranquilizers, and barbiturates.

The general use of these drugs presents a danger to public health when they are used indiscriminately. Therefore, nurses should be informed as to their responsibility to the doctor, the patient, and to themselves in regard to the use of these drugs.

This study was developed by presenting briefly the following:

  1. Principles and history of group discussion and problem situation unit teaching; …


An Investigation Into Nursing Students' Awareness Of Emotional Needs Of Patients In A General Hospital, Sadie Sinclair Jun 1958

An Investigation Into Nursing Students' Awareness Of Emotional Needs Of Patients In A General Hospital, Sadie Sinclair

Loma Linda University Electronic Theses, Dissertations & Projects

Nursing educators consider that awareness of the emotional needs of a patient is a prerequisite to the formulation of a nursing problem. The problem of this study was to discover if the senior student in a specific college program in nursing is aware of the emotional needs of patients. A collection of senior research papers written over a period of sic [sic] years in a specific course assignment was studied. The attention was focused on the portion of the paper which dealt with the personality description of the patient. The direction given by the instructor did not emphasize any particular …


Positions Held During The First Year Following Graduation By Graduates From College Programs In Nursing, Geneva Bowman Jun 1958

Positions Held During The First Year Following Graduation By Graduates From College Programs In Nursing, Geneva Bowman

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to find out what levels of responsibilities recent graduates of four Seventh-day Adventist basic college programs in nursing assumed during the first year following graduation; to find if these recent graduates felt adequately prepared for their positions; and to find out why they accepted their positions.

The descriptive survey method was selected for the research. The questionnaire, chosen as the means of obtaining data, was sent to the 106 nurses who graduated in 1956 of whom 82 percent responded. Data received was analyzed and tabulated by individual schools and collectively. However, conclusions were based …
