Phase Shift Analysis Of Protons Elastically Scattered By 016 Near EP = 8.3 Mev, Glenn D. Westin

Masters Theses

Chapter I

Introduction

The study of the resonances in the scattering cross section of the p + O¹⁶ reaction can reveal information regarding the energy levels of the compound nucleus F¹⁷. The analysis is simplified because of the zero spin of the O¹⁶ nucleus. Also, the low binding energy of the proton added to O¹⁶ allows examination of the low-lying energy levels in F¹⁷.¹ The reaction has been intensively investigated at the University of Wisconsin in a series of experiments using an electrostatic accelerator as a source of protons.

The Calculation Of The Cross-Section Of The Interaction Between Two Yang-Mills Fields, Richard A. Starr

Masters Theses

The Problem and Its Background

This thesis presents a study of the interaction between two arbitrary fields, named Yang-Mills fields¹ for their originators. The basic equations for the calculations of the Yang-Mills interaction are due to modern quantum field theory and its specific application to quantum electrodynamics.²

Much useful information can be obtained from the formulation of the dynamical equations for a classical system: for example, the classical description of the electromagnetic field, based on Maxwell's equations, leads to wave concepts. Then using this formalism as a starting point, one can proceed to the quantum theory of free …

Cerium Magnesium Nitrate Temperature Scale From Nuclear Orientation, Richard B. Frankel, D. A. Shirley, N. J. Stone

Physics

Systematic deviations were found below 0.003°K in the temperature dependence of nuclear orientation of Ce^137m in cerous magnesium nitrate, using the temperature scale proposed by Daniels and Robinson. The temperature scale below 0.006°K was redetermined using a new method: nuclear orientation. This has the advantage over the 'Y-ray heating method of high sensitivity at the lowest temperature. The most striking result is hat a value of 1/T of 520, rather than the previously accepted 324, is obtained by demagnetization from initial condItions of 18.8 kG deg^-1. The useful absolute temperature range is thus extended by …

Study Of The Stereochemistry Of A Carbanion Generated From An Azoacetate, Nguyen Thanh Buu

Masters Theses

Introduction

The reaction of lead tetraacetate with ketohydrazones to form azoacetates has been reported recently by Iffland, Salisbury and Schafer (13) and may be represented by the following equation:

R₂C=N-NH-R' + Pb(0Ac)₄ → R₂C-N=N-R' + Pb(OAc)₂ + HOAc OAc

Of principal interest has been the base-catalyzed decomposition of an azoacetate in a protonic solvent to give a ketone, a hydrocarbon, nitrogen and an acetate salt. The following sequence of steps has been proposed to account for these products (11).

Scaling In Isoelectronic Molecules, Jerry Goodisman

Chemistry - All Scholarship

A modification of a scaling method introduced for atoms by Ellison enables one to use expectation values calculated for one molecule in calculations of the energy of a second molecule isoelectronic to the first. In going from Hz to Hez2+t,h e results are only fair, but in going from LiF to BeO, the results are suffeciently good to allow prediction of equilibrium distance and several expectation values as well as energy. The dipole moment is a notable exception, which reveals one basic dissimilarity between the two molecules, the ionic character. LiF dissociates to ions, Be0 to neutral atoms, causing our …

Site Of Proton Ionization From Adenosine, Lee D. Hansen

Theses and Dissertations

The design, construction, and calibration of a precision thermometric titration calorimeter is described. This calorimeter was tested by determining the enthalpy change for ionization of water. The result, 13.34 ±0.03 kcal/mole (standard deviation), is in exact agreement with the best literature values. This standard deviation indicates that, using this calorimeter, ΔH values can be determined with an accuracy of ±0.0.5 kcal/mole. A calorimetric procedure has been developed for the, simultaneous determination of the equilibrium constant, the enthalpy change, and the entropy change for a chemical reaction from a single titration (Entropy Titration). This procedure has been tested by determining pK, …

Studies Of Rat Brain Thiamine Pyrophosphokinase, Lavell Rolfson Johnson

Theses and Dissertations

The enzyme ATP:thiamine pyrophosphotransferase (thiamine pyrophosphokinaseJ was purified from acetone powders which were prepared from rat brains up to the chromatography on alumina C_γ step by a modified procedure that Mano (Y. Mano, J. Biochem., 42, 283 (1960)] developed for the purification of the rat liver thiamine pyrophosphokinase. The enzyme was purified 12 fold over that in the original extract of the acetone powder. A spectrophotometric assay for the brain thiamine pyrophosphokinase was developed utilizing brewer's yeast apotransketolase. The transketolase assay was able to detect less than 10^-11 moles of thiamine diphosphate, which was synthesized by the kinase, in the …

Helianthus Annuus - The Separation And Identification Of A New Fatty Acid, Donald C. Gruber

Masters Theses

Introduction

The term "fatty acids" was first applied principally to saturated, monobasic carboxylic acids and especially to long chain acids derived from animal and vegetable oils. As time passed and the knowledge of natural fats increased, polyunsaturated, hydroxy, keto and branched chain acids were also found as constituents of these fats and oils and these also came under the heading of fatty acids. Even acids containing alicyclic substituents were found.

More recently the term 11 fatty acid" has been applied to include saturated and unsaturated monobasic carboxylic acids and several other series of substituted acids having carbon skeletons similar to …

Error Structure Of Randomized Design Under Background Correlation With A Missing Value, Tseng-Chi Chang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The analysis of variance technique is probably the most popular statistical technique used for testing hypotheses and estimating parameters. Eisenhart (12) presents two classes of problems solvable by the analysis of variance and the assumption underlying each class. Cochran (9) lists the assumptions and also discusses the consequences when these assumptions are not met. It is evident that if all the assumptions are not satisfied, the confidence placed in any result obtained in this manner is adversly affected to varying degrees according to the extent of the violation.
