Long-Range Particles From Nuclear Fission, Ralph A. Nobles

Physics & Astronomy ETDs

This work is concerned with experimental observations of the long-range particles which are occasionally emitted by fissioning nuclei. These particles are known to be principally alpha particles and are of interest because they are associated with the configuration of the nucleus at the crucial time of scission. Observations were made of the energy spectra of long-range particles by means of a thallium-activated multiple CsI crystal scintillator device.

A Thermodynamic Study Of Step-Wise Complex Formation In Several Aqueous Copper (Ii)-Amino Acid Systems, Vipin M. Kothari

Theses and Dissertations

pK_n values for step-wise dissociation of protons from the protonated ligands (glycine, α-amino isobutyric acid, sarcosine and theonine) were determined potentiometrically with a Beckman Model GS pH meter in aqueous solution at 10, 20, 30 and 40° C. Log K values for step-wise interaction of glycine, α-amino isobutyric acid, sarcosine and threonine with copper(II) ion were also determined potentiometrically with a pH meter at 10, 20, 30 and 40° C. The standard free energy of formation for the step-wise interaction of copper(II) with each of the above ligands was calculated from the values of log K. Enthalpy and entropy changes …

An Investigation Of Factors Relating To Turnover Among Nursing Personnel Of A Selected Hospital, Thelma I. Ogren

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to identify factors that contributed to the turnover among nursing personnel of a selected hospital in a large metropolitan city. It was felt that such a study would assist in the reduction of turnover among the nursing personnel.

Other similar studies revealed that reasons for turnover among hospital nursing personnel were due to low salaries, hours of work, work loads, communications, improper placement, poor supervision, and a lack of promotional opportunities. It was also found that the younger age group had a larger turnover rate than the older age group, that hospitals with schools …

Buttressing Effect In 3, 3' -Disubstituted-2, 2' -Three-Carbon-Atom Bridged Biphenyls, Yunn Hui Chiang

Masters Theses

Introduction

The configuration of biphenyl has been the subject of much investigation and many recent reviews (1, 5, 6, 7, 8, 17, 21, 22). Of particular interest has been the configuration of 2,2' -bridged biphenyl derivatives. The preparation of an optically active 2,2' -three-carbon-atom-bridged biphenyl having an ultraviolet absorption maximum at 250 mμ, has been recently described (14). Although the compound was easily racemized, this property requires that a non-planar configuration be assigned to this biphenyl (I). Furthermore, this ultraviolet spectra indicates that inter-ring conjugation must exist in the non-planar configuration.

Investigation Of The Platinum-Rich Portion Of The Platinum-Tantalum Phase Diagram, Bob Dean Browning

Theses and Dissertations

The Pt-Ta binary system was investigated at two isotherms;1000°C and 1500°C, and at eleven alloy compositions in the range of 50 to 100 atomic percent platinum. The alloys were examined by x-ray diffraction and metallography. Three intermetallic compounds, Pt₂Ta, Pt₃Ta, and Pt₄Ta were found to exist in this composition range. The Pt₄Ta intermetallic appeared only at the 1500°C isotherm. Platinum dissolved tantalum substitutionally to 90 atomic percent at 1500 °C and to approximately 80 atomic percent at 1000 °C.

Perfection Of The Lattice Of Dislocation-Free Silicon, Studied By The Lattice-Constant And Density Method, Martin E. Straumanis, Pierre Borgeaud, William Joseph James

Materials Science and Engineering Faculty Research & Creative Works

The lattice-constant and density method revealed that a high-purity silicon crystal free of dislocations has a perfect lattice without an excess of vacant sites or interstitials (n′=8.0000 4) within the limits of error, in agreement with the results obtained with the decoration method. The lattice constant of vacuum heated silicon powder of semiconductor purity was 5.43070±0.00004 A; that of the nonheat-treated powder was 5.43081 A at 25°C. The constants determined from crystal chips by the rotating crystal method were lower: between 5.43028-5.43048 A at 25°C. As the constants of each series of measurements could be reproduced very well (s=±0.00004 A), …

The Reaction Of N, N-Disubstituted Ketohydrazones With Lead Tetraacetate, Elisabeth Cerda

Masters Theses

Introduction

The reaction of lead tetraacetate with compounds of the following general structure (not able to enter here) was first reported by Iffland and Criner (12). In the case of ketoximes (A = oxygern), a nitrosoacetate was produced which was oxidized to the more stable acetoxy-nitrocompound as follows: (not able to enter here)

The generality of the reaction was established by preparation of a series of acetoxy-nitrocompounds from alicyclic and aliphatic ketoximes. The apparently similar reaction of cyclohexanonephenylhydrazone (A = N-¢) with lead tetraacetate was reported, but the reaction product was not identified.

Application Of Knowledge Of Medications By Senior Students In A Selected School Of Nursing, Patricia H. Okimi

Loma Linda University Electronic Theses, Dissertations & Projects

The problem arose from the need to study the present method of pharmacology instruction in a selected school of nursing. "How much knowledge of medications do selected senior students have, and how do they apply their knowledge in the administration of medications?"

For this study, the normative survey approach was used as the method of research. Eleven senior students of nursing engaged in the administration of medications, as team leaders, were observed and questioned on two different occasions during one quarter of their school year. The tool of research used to collect data was an observation code sheet developed for …

A Calibration Method For Satellite Cerenkov Instrumentals, Robert E. Dekinder Jr.

Physics & Astronomy ETDs

The problem posed for this thesis is one of determining a method of calibrating a photomultiplier tube when it is contained in an orbiting instrumentation package. Since it is planned for the satellite to remain in orbit for about two years, a method to determine drift of the telemetered output versus the selected radiation input would be very desirable. This drift could arise from changes in the power supplied to the system, or by the telemetering or logic circuits changing characteristics from exposure to cosmic radiation. The situation requires that light of constant intensity be produced in the "field of …

Angular Distribution Of Electrons In Extensive Air Showers, Don D. Laniewski

Physics & Astronomy ETDs

Electrons are the main products of an extensive air shower and comprise approximately 90% of the shower. Since these electrons are the most numerous particles near the axis of a large shower and are not easily detected, extensive air showers are most easily studied by means of the electronic component. Thus, whatever concern there may be about the nucleonic cascade of which the electron is an outgrowth, it is necessary first to understand the development of the electronic component and is lateral and angular distribution. Also, for the correct analysis of any experimental data, it is of particular importance to …

An Analysis Of Bursting Bubbles At Liquid Surfaces, Keith James Gilbert

Physics & Astronomy ETDs

This phenomenon of the spray produced by bursting bubbles at liquid surfaces is certainly familiar to drinkers of carbonated soda pop, champagne and other effervescent liquids. This same phenomenon has been observed at ocean surfaces. Small bubbles, some of which originate at great depths, rise to the surface and break; tiny droplet is thrown upward from most of the imploding bubbles. Some of these droplets may be caught and carried into the atmosphere by winds sweeping along the surface. The droplets evaporate but leave small particles of salt suspended in the air; the particles then serve as condensation nuclei and …

Mica schist and sillimanite hornfels occur in minor amounts. Other Precambrian rocks include medium-grained granite, splite and pegmatite dikes, and quartz veins. A minor amount of migmatite is present as a result of the intimate association of quartz-feldspar gneiss and …

Geology And Ground-Water Resources Of Northern Lea County, New Mexico, Sidney R. Ash

Earth and Planetary Sciences ETDs

The economy of northern Lea County is dependent upon groundwater; the only other source of water is the runoff from precipitation that is caught and retained in the man-made or natural reservoirs, where is it used for water stock. Irrigation utilizes most of the groundwater pumped; much smaller amounts are used for stock watering and industrial, public, rural and domestic supplies. In 1958, about 107,000 acre-feet of groundwater was pumped for irrigation and 19,000 acre-feet was pumped for all other uses. On the basis of present production of potable water, the economically usable supply will be depleted in certain areas …
