The study of two phase flow, where a finely divided solid is suspended in a fluid medium, has received considerable attention in the last five years due to the increased number of systems in which this phenomena occurs. The two most important areas involving the gas- particle mechanism are nuclear reactor heat exchangers and liquid and solid rockets.

Study Of Aerodynamic Forces On An Unsymmetrical Body As It Is Oscillated In A Air Stream, David Rees Tree

Theses and Dissertations

The object of this work was to design and build equipment to measure the aerodynamic forces which will cause self-induced oscillations of a body having an unsymmetrical cross-section, such as a D-section. This self-induced oscillation has been called "stall flutter" or in electrical transmission lines, "galloping-transmission lines." It is hoped that this equipment will be used to gain basic Information about these aerodynamic forces.

Thermodynamics Of I) Metal Cyanide Coordination, Ii) Water Formation, And Iii) Metal Halide Coordination, John Dewey Hale

Theses and Dissertations

ΔH values for the formation of Ni(CN)4(aq)= have been determined calorimetrically at 25° using a simple calorimeter and a thermometric titration procedure at high and low ionic strengths, respectively. Extrapolation of these ΔH values to infinite dilution resulted in a ΔH° value of -42.7 kcal./mole. Combination of ΔH° and ΔF° values gives a ΔS° value of -5.5 e.u. for Ni(CN)4(aq)= formation. A value of +70 e.u. is calculated for the ionic entropy of Ni(CN)4(aq)=. A preliminary investigation of the Zn(CN)4(aq)= system indicated the existence of zinc cyanide complexes other than Zn(CN)4= and allowed calculation of an approximate ΔH° value of …

A Study Of The Vibration Characteristics Of A Thin Shell Hyperbolic Paraboloid, Farrin W. West

Theses and Dissertations

Recent progress in structural engineering has been marked by the increased use of thin shells as load carrying members. In particular, shells of revolution have been widely utilized in the missile industry whereas shells of arbitrary shape have been incorporated in the architectural design of today's modern buildings. Missile applications have been extensively studied both statically and dynamically. However, architechural applications have generally been limited to the statics problem with little consideration being given to the dynamic behavior of these unique structures.

Directive Effects In The Sulfonation Of Toluene ; Synthesis And Attempted Rearrangement Of Some Anilinoketones ; The Kinetics And Mechanism Of The Addition Of Bromine To Cyclohexene In Dichloromethane. Solution, John Joseph Duvall

Theses and Dissertations

The pure sodium salts of the toluenesulfonic acids were prepared by one of two ways. Both methods started with diazotization of the toluidine. In the first method, the diazonium solution was treated with sulfur dioxide and copper powder, and the resulting sulfinic acid was oxidized to the sulfonic acid with potassium permanganate. In the second method, the diazonium solution was treated with cuprous chloride and sulfur dioxide to give the sulfonyl chloride which was hydrolyzed to the sulfonate. Toluene was sulfonated by SO3 (enriched with S-35) in refluxing SO2 solution. The isotope dilution technique was used to determine the isomer …

A Proposal To Reduce Misallocation Of Livestock Grazing Permits, B. Gardner Delworth

Faculty Publications

The federal government owns about 400 million acres of land in the eleven western states. Almost 350 million acres are administered by the Forest Service and Bureau of Land Management. In times past most of this land has been used for grazing by domestic livestock. Only approximately 60 million acres of forest range are presently grazed by livestock, while about 160 million acres of "district" land, administered by the BLM, are grazed.

Latter-Day Prophets And Present-Day Curriculum, Neil J. Flinders

Theses and Dissertations

A gap exists between the religious ideals of human behavior and the common practices of man. Considerable effort has been expended in attempts to discover how to teach men to behave in ways that would be acceptable to society and still satisfy the ideals of the various religions. This problem is one of the major concerns of religious education.

In an effort to solve the above problem among its membership, the Church of Jesus Christ of Latter-day Saints has established a program of week-day religious instruction, commonly referred to as the "Seminary program." This organization is currently engaged in an …

The Spectrum Of Faith In Victorian Literature, Bruce B. Clark

BYU Studies

Typical of the schismatic nature of its time, Victorian literature holds all four fundamental religious positions mankind can take: liberalism, fundamentalism, humanism, and existentialism. Robert Browning's work serves as an example of optimistic and affirmative liberalism. Christina Rossetti represents the pessimism toward life and the ultimately hope for the next life of fundamentalism. Mathew Arnold's work illustrates the opposite, humanist point of view, which displays optimism for the present but has no belief in an afterlife. Finally, James Thompson displays the negativity of existentialist thought, seeing little hope in the present and future.

A New Emphasis For The American Dream, Weldon J. Taylor

BYU Studies

The American ideals of hard work, thrift, and perseverance are rooted in mankind's desire to meet his basic physical needs. Since in today's society these needs are not as pressing, the basic American values have begun to lose their motivating power. Today, the desire to be a creative and valued member of an organization should become a bigger motivator than the simple drive for wealth. Some whose comments have contributed to the idea of this new motivation include O. A. Ohmann, A. A. Stambaugh, Abraham T. Collier, and Stanley F. Teele.

“Snake”: A Moment Of Consciousness, Robert O. Dalton

BYU Studies

If a reader judged D. H. Lawrence's "Snake" based solely on its form, the poem could easily be disregarded. However, Lawrence's intense effort to capture a moment of enlightenment and the reader's emotional involvement in the poem overcome Lawrence's supposed inattention to form and show that there is much to be appreciated in "Snake."

A Parametric Study Of The Heat Transfer Characteristics Of A Moving Band Heat Exchanger, Larry Hyde Brim

Theses and Dissertations

In recent years much attention has been devoted to the development of efficient heat exchangers. The regenerative or moving matrix heat exchanger is one type which has been considered. Most regenerative heat exchangers use one of the conventional types of high area matrices mounted in a drum or disk in such a manner that it can be moved in a continuous cycle from a cold fluid stream to a hot fluid stream and back again. A rather different approach to the design of a regenerative heat exchanger which has been patented in this country is a set of flexible moving …

Kinetic Investigation Of The Hydrochlorination Of Olefins In Aprotic Solvents And Sulfonation Of Idobenzene And The Selectivity Relation, Thomas Glen Davies

Theses and Dissertations

Kinetic investigation of the hydrochlorination of cyclohexene and cis-2-butene in n-heptane with SnCl4 as catalyst shows that the reaction is second order with respect to both olefin and catalyst. The specific rate constants at 25° , 0° and -23.8°C and the activation parameters were determined. Investigation of the Ga2Cl6 catalyzed hydrochlorination of cyclohexene and cis-2-butene in dichloromethane indicates that alkylation and polymerization compete with the hydrochlorination reaction in the presence of the solvent. The relative reaction rates and the isomer distribution for the sulfonation of iodobenzene by S35O3 have been determined in refluxing SO2 at -10°C. The reaction resulted in …

Sulfonation Of Chlorobenzene And The Selectivity Relation ; Bromine Addition To Cyclohexene In Dichloromethane ; Thorpe's Synthesis Of The Caged Acid, 4-Methyltricyclo[1.1.0.0[Superscript 2-4]] Butane-1,2,3-Tricarboxylic Acid, John A. Gurney

Theses and Dissertations

Aromatic sulfonation and some substitution reactions of chlorobenzene show deviations in the selectivity relation. A determination of chlorobenzene sulfonation provided the following rate ratio relative to benzene and partial rate factors: 1.0, [---] of 0.064 , mf 1.7 and pf 4. 2. Our work, Olah's nitration, Ferguson's bromination and Stock's chlorination define a new relation that can be express by adding an entropy term (A) to the selectivity relation. We determined the rate of bromine-cyclohexene addition in dichloro-methane at 0° to provide a basis for a systematic variation of solvents at low temperature. An unusual zero-order reaction was encountered. The …

Part Iii., Preliminary Survey On The Effect Of High Pressure On Ferrocene And Cycloöctatetraene, Jerold Carter Robertson

Theses and Dissertations

Part I. The rearrangement of α-anilinoketones was studied in an effort to determine the mode of movement of the nitrogen moiety. A crossover experiment was carried out with an equimolar mixture of 2-(4- bromoanilino)-1-(4-bromophenyl)-2-(4-methoxyphenyl) ethanone and 2-(4-chloroanilino)-1-(4-chlorophenyl) -2-(4-methoxyphenyl)ethanone with γ- picoline hydrobromide as the catalyst. The reaction product was analysed by means of a mass spectrograph. The results of the analysis indicate a crossover of the nitrogen moiety during rearrangement. This indicates that the nitrogen moiety moves in an intermolecular manner during the rearrangement. Part II. The isomer distribution from the sulfonation of bromobenzene with sulfur trioxide was determined by …

Stress Analysis Of An Infinite Cylinder With An Irregular Shaped Cavity Using Complex Variable Techniques, Gerald H. Lindsey

Theses and Dissertations

The advancement of modern technology has brought with It a demand upon the engineer for more thorough analysis techniques. This has been precipitated by the advent of missiles and space-craft that do not permit regular inspections to determine causes of failure, crack propagation, design weaknesses, etc. Thus, a more complete analytical work must be performed to facilitate a foreknowledge of reaction and performance of a particular design to its environment.

The Taxonomic Problem Of Polycelis In The United States, Lee F. Braithwaite

Theses and Dissertations

During the spring of 1941, Dr. C.L. Hayward, of the Brigham Young University zoology department, while on a field trip with his ecology class found some interesting planaria.ns at a place called Stewart's Flats on Mt. Timpanogos, Utah County, Utah. A fellow teacher, Dr. D. E. Beck, sent live specimens to Dr. L. H. Hyman of the American Museum of Natural History for identification. Although the specimens arrived in New York as a "putrid smelling soup,"1 the specimens, through correspondence, were thought to be Polycelis coronata (Girard), the same species Hyman collected in South Dakota during August 1929.

Diffraction Of Spherical Scalar And Vector Waves At Axial Points Of A Circular Aperture And Disk, Keith Leon Mcdonald

Faculty Publications

The following work treats Kottler's saltus problem of diffraction of electromagnetic waves emitted by a Hertzian oscillator source and the analogous Kirchhoff's scalar problem of waves emitted by a point source. The medium is a homogeneous isotropic dielectric. In the vector case a new exact solution of the basic integrals is presented, at axial points only, (a) behind a circular aperture in a "black'' screen, and (b) behind its complementary "black'' disk. The relative time-averaged intensity of energy flow is plotted for the disk only. It is shown that the scalar theory predicts considerably larger values than the electromagnetic theory …

An Investigation Of Coulometric Methods Of Analysis Of 1,1-Dimethylhydrazine, David M. Creighton

Theses and Dissertations

The oxidation of 1,1-dimethylhydrazine by bromine has been studied using a coulometric method of bromine generation, and a dual intermediate system of bromide and cupric ions in solution. The system allowed over-generation of bromine and back-titration by cupric ion. The results of the investigation showed that the mechanism of oxidation is not fixed, but is a function of the concentration of bromine in the solution at any time. Additional studies have been recommended, whereby the mechanisms of the reactions may be determined.
