Solid-Liquid Phase Equilibria Of The Sodium-Rubidium And Sodium-Potassium-Rubidium Alloy Systems, Chen-Chao Hsu Aug 1969

Solid-Liquid Phase Equilibria Of The Sodium-Rubidium And Sodium-Potassium-Rubidium Alloy Systems, Chen-Chao Hsu

Theses and Dissertations

Thermal methods were used, to determine with high precision, the solid-liquid phase equilibria diagrams for the sodium-rubidium and sodium-potassium-rubidium systems. In the sodium-rubidium system, the results differ greatly from those of earlier works, especially near the eutectic composition where differences in freezing points as large as 25°K occur. A detailed search was made for possible intermetallic compounds (especially Na2Rb). Neither slow temperature cycling in the temperature range where compound formation could occur nor extended periods of annealing just above the eutectic temperature produced any evidence for compound formation in the sodium-rubidium system. A 2:1 (sodium to rubidium) sample was subjected …

Mechanism Of Water Transport Through Reverse Osmotic Membranes, Cheryl Kay Murphy Jul 1969

Mechanism Of Water Transport Through Reverse Osmotic Membranes, Cheryl Kay Murphy

Theses and Dissertations

Cellulose acetate membranes show a higher permeability to water than to salt and are being used for desalination of salt water by reverse osmosis. Use of highly acetylated cellulose membranes give a higher salt rejection but also decrease flow rate of the water. The addition of very-short-chain substances or alkyl groups larger than one carbon atom to the cellulose membrane also decreases water flux. A proposed mechanism of transport through the membrane is that the water molecule is passed along the chain by hydrogen bonding with the acetyl groups, The NMR shows a change in the chemical shift of water …

Inhibition Of Asexual Reproduction In Planaria, Lewis Hafen Leavitt Jul 1969

Inhibition Of Asexual Reproduction In Planaria, Lewis Hafen Leavitt

Theses and Dissertations

Asexual reproduction in the decapitated planaria, Dugesia dorotocephala, is inhibited by an extract of homogenized heads of the same or closely-related species. Decapitated planaria allowed to regenerate have reproduced asexually over 80% of the time, while those that have been cultured in a suspension of head homogenate have had asexual reproduction inhibited to less than 10%. The substance that inhibits asexual reproduction is heat labile. It requires a concentration of 2.0 heads/ml that contains .13 mg protein/ml to effectively inhibit asexual reproduction. A similar concentration of head homogenate from the related planaria, Dugesia tigrina, also contains the inhibitory substance. Head …

Theses and Dissertations

Earlier work in these laboratories on the heterotricyclic system 2,6-dioxa-10-azatricyclo[5.2.1.04,10]-decane, formed from 1,4-diketones and 2-amino-1,3-propanediols by a product-water-azeotroping procedure, was extended with the synthesis of analogous compounds, e.g., the 1,4,7-triethyl-, 1,7-dimethyl-4-isopropyl-1,7-diethyl-4-isopropyl-, 1,7-dimethyl-3- and 4-phenyl- compounds. The 1,7-dimethyl heterotricycle, the kinetically-controlled product, was accompanied by the thermodynamically-controlled product, 2-(2,5-dimethyl-1-pyrryl)-1,3-propanediol. The 1,7-diethyl heterotricycle was also accompanied by the isomeric pyrrole as were the 1,7-dimethyl-3- and 4-phenyl compounds. A scheme postulating a common intermediate is presented. The interesting analogous compounds, 1,7-dimethyl-2-oxa-6-thia-10-azatricyclo[5.2.1.04,10]decane, 1,4,7-trimethyl-2,6-dioxa-11-azatricyclo[5.3.1.04,11]undecane and 11-hydroxymethyl- and 11-methyl-9,13-dioxa-14- azatetracyclo[6.5.1.02,7 011,14]tetradeca-2,4,6-triene were also prepared. The syntheses in good yields of a considerable number of moderately to …

High Pressure, High Temperature Syntheses Of Selected Lanthanide-Tellurium Compounds, John Francis Cannon Jun 1969

High Pressure, High Temperature Syntheses Of Selected Lanthanide-Tellurium Compounds, John Francis Cannon

Theses and Dissertations

High pressure, high temperature technics were employed to successfully synthesize HoTe1.7, ErTe1.7, TmTe1.7, LuTe1.7, YTe1.7, and LuTe3. The pressure-temperature regions in which synthesis of each compound is successful were determined. Pressures to 100 kbars concurrently with temperatures to 1200 °C were used in an attempt to prepare ScTe1.7 and ScTe3, but these efforts met with failure. X-ray studies of these new compounds confirmed that they are extensions of the LTe2-X (0≤x

George Romney In 1968, From Front-Runner To Drop-Out, An Analysis Of Cause, Richard M. Eyre

Theses and Dissertations

The meteoric political decline of George Romney is unparalleled in political history and in the history of presidential campaigning. In the space of one year, the man evolved from the overwhelming presidential favorite of Republicans, Democrats, and Independents alike to a presidential drop out, criticized severely and even mocked by press and public alike.

There are many opinions as to why this phenomenon occurred. The press has opinions, the public has opinions, and the people closest to George Romney have opinions.

A step by step analysis of Romney's campaign casts light on these opinions and completely discredits some while validating …

A Study Of The Definition Of The Gospel Of Jesus Christ And Its Theological Implications In Latter-Day Saint Literature, David Earl Perry Jan 1969

A Study Of The Definition Of The Gospel Of Jesus Christ And Its Theological Implications In Latter-Day Saint Literature, David Earl Perry

Theses and Dissertations

This thesis attempts to treat four problems: What is the gospel, as defined in Latter-day Saint literature? Do ancient and modern sources agree? Has there been an historical development of the definitions? Can any disagreements be rationalized? The results of this research reveal that the gospel is complex in that it is capable of handling all the problems of eternity, yet it is simple in that it is a plan of specific principles which lead man step by step to perfection. The author determined that ancient and modern sources do agree in placing six "first principles" at the beginning of …
