Acidic Properties Of Clay Minerals And Alumina, Kenneth H. Anderson Aug 1955

Acidic Properties Of Clay Minerals And Alumina, Kenneth H. Anderson

Theses and Dissertations

Acidic properties of dialyzed alumina and representative clay minerals were studied by performing titrations with various bases. For the first group of experiments the titrations were made in a water system using KOH and NaOH. For this study in a water system the experimental data includes individual cationic activities as well as pH values. Adsorption of the cations was adequately described over a pH range of 5-11 by the equation 1-θ/θ ⋅ aNa+ ⋅ aOH- = 1/K'3 [aOH- + KW/K'2 + 1/K'1], in which θ represents the fraction of the total sites that have reacted. Thermodynamic constants K'3 and K0= …

The Effect Of Ferrous And Ferric Ions On The Conversion Of Malate To Pyruvate By A Cell Free Extract Of Pigeon Liver, Keith Erwin Richardson Jul 1955

The Effect Of Ferrous And Ferric Ions On The Conversion Of Malate To Pyruvate By A Cell Free Extract Of Pigeon Liver, Keith Erwin Richardson

Theses and Dissertations

Recent investigations on the crude pigeon liver extracts have shown the presence of an enzyme which catalyzes the oxidative decarboxylation of malate to pyruvate and carbon dioxide. The name malic enzyme has been given to this enzyme to distinguish it from malic dehydrogenase. Under aerobic conditions the addition of ferrous sulfate resulted in inhibition of the action of malic enzyme. Subsequent investigation showed that the inhibition obaerved was not due to ferrous ions, but due to ferric ions which were contaminating the ferrous sulfate. It was also shown that under aerobic conditions ferrous ions were rapidly oxidized to ferric ions. …


Colorimetric Determination Of Rhenium In Ores, Clair Winston Rogers Jul 1955

Colorimetric Determination Of Rhenium In Ores, Clair Winston Rogers

Theses and Dissertations

The problem of colorimetrically determining rhenium in the presence of molybdenum, copper, iron, sulphur, and rare earth elements with the use of dimethylglyoxime as the complexing compound was accomplished by the method reported here-in. The interfering elements were eliminated either as gaseous oxides and sulfides or were precipitated from a highly basic solution by means of a strong alkaline fusion of equal weights of sodium hydroxide and sodium peroxide, and the ore sample containing rhenium. The fusion product was dissolved in water, the solution boiled with a slight excess of sodium peroxide, and the hydroxide of all the interfering ions …

Thermodynamic Properties Of Water Adsorbed On Kaolinite, S. John Bennett Jun 1955

Thermodynamic Properties Of Water Adsorbed On Kaolinite, S. John Bennett

Theses and Dissertations

The object of the work presented in this thesis was to obtain quantitative values of the thermodynamic changes in water upon adsorption by kaolinite. Two methode were used. The first was a determination of the differential heat content and entropy of adsorption. The second method included a thermodynamic evaluation of the B.E.T. "c" constant expressed in terms of the Gibbs standard free energy of adsorption. The experimental data gave satisfactory results in determining the differential and standard thermodynamic functions or free energy, entropy, and heat content of adsorption. The adsorption of water on kaolinite appears to be a van der …


A Study Of The Problem Of A Personal Devil And Its Relationship To Latter-Day Saint Beliefs, Lamar E. Garrard May 1955

A Study Of The Problem Of A Personal Devil And Its Relationship To Latter-Day Saint Beliefs, Lamar E. Garrard

Theses and Dissertations

The problem of the existence of a devil is important, since it relates to other beliefs which a person or his religion may uphold. The orthodox Christian concepts of the divinity of Christ, the Fall of man, the Atonement, and the inspiration of the Bible are altered when a belief in Satan is discarded.

The prophets of the Church of Jesus Christ of Latter-day Saints (Mormon) take a very definite stand concerning the existence of Satan. They declare that the devil and his angels exist and that they tempt and try to deceive men. L.D.S. scriptures, given through modern revelation, …
