Mechanism Of Adsorption Of Cations By Silicate Minerals, Milton Glen Armstrong
Mechanism Of Adsorption Of Cations By Silicate Minerals, Milton Glen Armstrong
Theses and Dissertations
Adsorption of cations by clays has been a subject of investigation for many years. Many proposals have been advanced to explain this process of adsorption. Two proposals have been prominent in recent years. The Marshall "charged lattice" theory attributes adsorption of cations by clays to an electrostatic attration of the clay particles for cations. This charge on the clay particles is attributed to various isomorphic substitutions in the lattice of the clay which result in an unbalanced charge on the particle. This isomorphic substitution can take place either in the silicon-oxygen tetrahedra of the silicate structure or with the aluminum …

The Position Of Adam In Latter-Day Scripture And Theology, Rodney Turner
The Position Of Adam In Latter-Day Scripture And Theology, Rodney Turner
Theses and Dissertations
The purpose of this study is to determine, in so far as is possible, the views held by various leaders of the Latter-day Saints relative to Adam; and more especially, the official doctrine of the Church as to his place in its theology.
The problem is based, in part, on the divergent, and oft times bitter, claims and counter-claims of members, ex-members, and non-members of the Church of Jesus Christ of Latter-day Saints over "Mormon" teachings concerning Adam in the light of a certain address given by president Brigham Young in 1852. Indeed, this address, and the man who gave …

Thermodynamic Properties Of Water Absorbed On Silica, Conrad V. Hatch
Thermodynamic Properties Of Water Absorbed On Silica, Conrad V. Hatch
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 silica. Two methods were used. The first was a determination of the differential entropy and heat of adsorption independent of any theory of adsorption. The second method included a new interpretation of the "c" constant of the Brunauer, Emmett, and Teller Theory in which c was expressed in terms of the standard free energy of adsorption. The experimental data gave satisfactory results in determining the differential heat and entropy of adsorption. The results obtained in determining the …

Further Studies Of The Reactions Of Quinoxaline And 2-Methylquinoxaline, Marcus N. Myers
Further Studies Of The Reactions Of Quinoxaline And 2-Methylquinoxaline, Marcus N. Myers
Theses and Dissertations
The present investigation was also made with the object of preparing the vinylquinoxalines and studying their 1,4- addition reactions. The attempts to prepare vinylquinoxalines were unsuccessful. However, sodium acetylide reacted with 2,3-dichloroquinoxaline to give a new compound which (from its analysis and properties) appears to be 2,3-bis(1-hydroxyethyl) quinoxaline . This new compound should be investigated further , as it may prove to be an intermediate in the preparation of vinylquinoxalines. The preparation of 2-methylquinoxaline has become very simple by the use of the method of Jones, Kornfeld and McLaughlin^5, which consists of condensing o-phenylenediamine with pyruvic aldehyde. The condensation of …

Evidences Of Culture Contacts Between Polynesia And The Americas In Precolumbian Times, John L. Sorenson Sr.
Evidences Of Culture Contacts Between Polynesia And The Americas In Precolumbian Times, John L. Sorenson Sr.
Theses and Dissertations
Of the great unsettled problems of archaeology and anthropology perhaps the most hotly debated has been the relative importance of migration, diffusion, and independent invention in the origin of culture elements. The question has obvious importance, both for a proper understanding of man and culture, that ambitiously comprehensive goal of modern anthropology, and for historical reconstruction, the latter a necessary preliminary of the former.
The concern of this thesis is with culture movement in the eastern Pacific Ocean area. The Pacific area as a whole has long been the geographical center of the diffusion problem (if we may so term …

Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy
Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy
Theses and Dissertations
During the period of October to April of the winter of 1950-51, an ecological study was undertaken of a population or passerine birds wintering in a segment of the Utah Lake Shore. Available winter weather data indicated that although such factors as precipitation, temperature, and wind may often be severe, they are not critical enough to prevent a fairly large population of passerine birds from spending the winter months in the study locale. Five fairly distinct plant communities can be recognized in the area. There is evidence which indicates that certain passerine bird species are especially dependent on a particular …

Textual Parallels To The Doctrine And Covenants And Book Of Commandments As Found In The Bible, Ellis T. Rasmussen
Textual Parallels To The Doctrine And Covenants And Book Of Commandments As Found In The Bible, Ellis T. Rasmussen
Theses and Dissertations
The problem of this thesis is: What textual relationship does the Doctrine and Covenants of the Church of Jesus Christ of Latter-day Saints bear to the Bible, King James Version?
As a preliminary hypothesis, it has been assumed that there are phrases and clauses in the Doctrine and Covenants similar enough in construction and meaning to some of the phrases and clauses in the Bible to permit selection of samples from both that will parallel each other. Whether such parallel phrasing, when found, would appear to be a result of quoting, adapting, reiterating, renewing, alluding or simply coincidental construction constituted …
History Of The Provo Times And Enquirer 1873-1897, Robert D. Anderson
History Of The Provo Times And Enquirer 1873-1897, Robert D. Anderson
Theses and Dissertations
The home of the Provo Times and Enquirer was a typical Mormon town founded on the east shore of Utah Lake in 1849. While some Gentiles (non-Mormons) had moved into the area by 1873 when the first newspaper appeared, the community was still dominated and controlled by members of the Latter-day Saint Church, which was the cause of some tension.
Even though after twenty-four years of settlement Provo had well-established farms, businesses, and the beginnings of industry, it did not have a newspaper, although publications had been founded earlier in several other cities of the territory. In the winter of …

An Electrochemical Determination Of The Free Energy Of Formation And Solubility Product Constant Of Silver And Mercury Sulfides, Earl Lloyd Gray
An Electrochemical Determination Of The Free Energy Of Formation And Solubility Product Constant Of Silver And Mercury Sulfides, Earl Lloyd Gray
Theses and Dissertations
Because present data on free energy of formation and solubility product constants of the metal sulfides are both inconsistent and based on very old experimental data, a new study using modern techniques is amply justified. Because metal sulfide precipitates are often colloidal and becasue the solubility of these sulfides is so low, ordinary physical and analytical methods are not applicable to a direct determination fo the solubility product constant. Therefore, a more reliable thermodynamic approach was undertaken in this study. The standard free energy of formation of silver and mercury sulfide was determined from electromotive force measurements of suitable galvanic …
Further Studies Of The Reactions Of Quinoxaline, 2-Methyl-, And 2,3-Dimethylquinoxaline, Chester E. Hamilton
Further Studies Of The Reactions Of Quinoxaline, 2-Methyl-, And 2,3-Dimethylquinoxaline, Chester E. Hamilton
Theses and Dissertations
A long term research program into the chemistry of quinoxalines has been instituted at Brigham Young University. The literature of quinoxaline chemistry was reviewed and assembled in one paper. Methods of preparation of 2,3-dimethyl- and 2- methylquinoxaline were studied and improved. The bromination of 2,3-dimethylquinoxaline using N-bromosuccinimide was accomplished and an anil addition using quinoxaline and phenyllithium was achieved. Efforts to prepare vinylquinoxalines were unsuccessful. In order to pursue an investigation into the numerous reactions of the 1,4 addition type, a method of preparations of vinyl-quinoxalines must be achieved. In the present investigation, various methods of synthesis of vinyl- and …
