Heats Of Combustion Of Alpha-Methylstyrene Oligomers, Dale Keith Humbert

Masters Theses

Introduction

The heat of polymerization (∆H_p) of α-methylstyrene (AMS) has been a source of study for many years. The structure of AMS is shown in Figure 1.

The first quantitative work was done by Roberts and Jessup.¹ Their values were more positive than those theoretically calculated by Flory² and compared with ∆H_p data of other systems. This was not totally unexpected and could be satisfactorily explained on the basis of steric hindrance and loss of resonance energy of conjugation. This steric hindrance arose from "head-to-tail" polymerization of the 1, 1-disubstituted ethylene structure.³ Their data …

The Hemoglobin Of Tubifex Tubifex, Lalitchandra Vrajlal Vora

Masters Theses

The hemoglobin of Tubifex tubifex is found in solution in the blood of the worm in cells as in vertebrates. The binding of oxygen to the hemoglobin can be followed spectrophotometrically. A peak of absorbtion at 540 nm is fairly constant under different condition, while a peak at 575 nm disappears from the spectrum when oxygen is removed. The hemoglobin contains heme, non-heme iron and protein.

Binding of oxygen to the hemoglobin was found to be dependent on the concentration of the hemoglobin, at low concentrations (4.16 x 10^-6 M), oxygen could not be removed from the hemoglobin. Only …

The Conductance Of Some Non-Rigid Bolaform Electrolytes, William Terry Schmidt

Masters Theses

Bolaform electrolytes are those which contain two or more charges separated by an inert framework. These are intermediate in structure between simple electrolytes and polyelectrolytes. Since these are similar to both synthetic and biological electrolytes, this investigation has been undertaken to determine some of their properties in solution.

The sodium and magnesium salts of ethane, propane, butane, pentane, hexane and decane α,ω-disulfonates were prepared. Each acid was prepared by refluxing the α,ω-dibromide of the desired salt with sodium sulfite. The sodium and magnesium salts were prepared by ion-exchange techniques.

The conductance of each salt was determined in methanol utilizing the …

Squillites Spinosus (Syncarida, Malacostraca) And A New Unnamed Crustacean From The Mississippian Of Central Montana, Joan Matthews Rumore

Masters Theses

A Mississippian syncarid from the Heath shale, Squillites spinosus Scott, 1938, is redescribed and a discussion of some aspects of Syncarid phylogeny is given. Modern Syncarid biogeographical distribution is discussed and an analysis of these zoogeographical patterns is provided. A strange animal, Crustacea (incerta sedis) from the Heath shale is described in as far as is possible.

In 1971, Dr. Richard Lund of the University of Pittsburgh while searching for fossil fish in the Upper Mississippian Heath Shale of Montana found the associated remains of fossil crustaceans. Two locations were involved, T14 N R20E sec. 28, Fergus County, Montana, 2 …

Range And Optimum Growth Concentrations Of Phosphate And Nitrate For Chlamydomonas Reinhardtii, Thomas E. Hill

Masters Theses

A study was conducted on the alga Chlamydomonas reinhardtii to determine the range and optimum growth concentrations of phosphate and nitrate. There are only a few species of algae for which this type of data is known. Inorganic nutritional data is basic to the understanding of the complexities of phytoplankton ecology and eutrophication.

The "plus" strain of this heterothallic alga was cultured in a TRIS-buffered inorganic medium with various concentrations of sodium phosphate and potassium nitrate and adjusted to a pH of 7.4. The axenic cultures were evaluated at the end of 6 days with a spectrophotometer, at a wavelength …

Experimental Study Of Neutron Reflection From A Cylindrical Surface, Dale Lee Holtzscher

Masters Theses

"The reflection patterns for an elliptical neutron beam impinging upon cylindrical and planar surfaces were measured. The flux intensity as a function of distance from the surface of either planar or cylindrical reflectors decreased monotonously with distance. No "focusing" of the neutron beam appeared in the case of the cylindrical reflectors but the flux did not decrease as rapidly as in the planar case. For the elliptical neutron beam the experimentally determined neutron flux distribution agrees with calculation"--Abstract, page ii.

Development Of A Sampling System And Characterization Of Stormwater Runoff From A Small Urban Area, William Clark Ford

Masters Theses

"Increasing urbanization and the demand for high quality water have directed attention to the problem of combined sewer overflows, while recent research has demonstrated that stormwater alone, without the influence of sanitary sewage, carries a significant pollutional load. The purpose of this investigation was to determine the quality and pollutional contribution of stormwater runoff from a small urban area, with specific emphasis on the development of a suitable sampling and flow recording system, the characterization of runoff and the correlation of runoff quality with local environmental factors and storm characteristics. The system developed consisted of an automatic sampler capable of …

Application Of Transmission Matrices To Describe Transverse Vibrations Of Non-Uniform Bernoulli-Euler Beams, Dean Irle Parker

Masters Theses

"This report investigates the application of transmission Matrices to determine natural frequencies of non-uniform Bernoulli-Euler beams. The classes of non-uniform beams considered includes: truncated wedges, truncated cones, and truncated rectangular pyramids. Two transmission matrices were derived from solutions to the Bernoulli-Euler equation. One was an exact closed form solution which was applicable for the above classes of beams excluding uniform and nearly uniform beams. The second solution was an approximate one limited to the use for nearly uniform beams, but which does give the correct solution to the uniform beam in the limiting case. The transmission matrix has two advantages: …

The Analog Simulation Of Heat Transfer Devices For The Smoothing Of A Fluctuating Fluid Temperature, Le Thai Son

Masters Theses

"Equations are written to describe a heat exchanger with electrical energy input and also a large tank system which can have electrical energy input. The output temperatures were sampled and fedback to define the energy input to the two systems. These systems were simulated on an analog computer and the ability of the two systems to smooth a fluctuating temperature input was tested. The testing of the systems included trying different types of controllers in the control system as well as different size tanks for the tank system. A satisfactory smoothing of the output temperature was demonstrated after some modifications"--Abstract, …

The Electric Field Strength Dependence Of Neutron-Induced Defects In Silicon P-N Junctions, Paul Edward Johnson

Masters Theses

"The effect of high electric field strengths (10⁴ to 10⁵ V/cm) present during neutron radiation on the neutron-induced defects is determined by utilizing the high electric field strength inherent in the emitter-base transistion region of an n-p-n transistor. A method is presented for the separation of neutron and gamma effects. Previous theoretical work on the ratio of base current increase to collector current decrease is applied to experimental data. The variations of the space-charge region volume damage introduction rate with neutron fluence and the average electric field strength are determined experimentally in order to obtain a measure of this effect. …

Wind Tunnel Modeling Of The Atmospheric Boundary Layer, Sreemanth Pagadala

Masters Theses

"The importance of simulating atmospheric flows in wind tunnels has been well established. Experiments were conducted in the Modified Aerodynamic Wind Tunnel to determine the suitability of this wind tunnel for simulating atmospheric flows and the degree to which various aspects of modeling could be fulfilled. A temperature profile to simulate the inversion aloft was generated inside the test section, and then an appropriate velocity profile was built in by means of screen mesh arrangements. The turbulence characteristics of the flow were measured. The validity of the temperature, velocity and turbulence fields were examined. It was found that while the …
