Part I. Catalytic Hydrocarbon Reforming By Technetium Catalysts.|Npart Ii.|Pacetone Azine And 3,5,5-Trimethyl-2-Pyrazoline Adducts Of Palladium Chloride, James Lynn Palmer

Theses and Dissertations

Technetium catalyzes hydrocarbon reforming reactions of dehydrocyclization, isomerization, hydrogenolysis, and coke formation. A kinetic equation was derived and E_a and A_o evaluated for dehydrocyclization of n-heptane, isomerization of n-pentane, and dehydrogenation of methylcyclohexane and cyclohexane. The results were related to the metal, the form of the catalyst, catalyst support, and the deactivation of the catalyst. The effect of sulfur compounds was determined. No residual radioactivity in the product was observed. The ligands, acetone azine (AA) and 3,5,5-trimethyl-2- pyrazoline (Py), reacted with (C_6H_5CN)_2PdCl_2 to form adducts, L_2PdCl_2 and (LPdCl_2)_n. Their structures were characterized by spectroscopic methods and some molecular weights determined. …

Thermodynamic Stability Constants Of Silver Bromide Complexes In Water And Water-Acetone Mixtures Determined By Ion-Selective Electrode Measurements, Arthur Lee Cummings

Theses and Dissertations

Thermodynamic equilibrium constants for silver(I) bromide complexes were determined by ion-selective membrane electrode potential measurements in water and in mixtures of water and acetone of approximately 5, 10 and 15 percent acetone by weight. Values of the solubility product constant were determined in each solvent system by calibration of a silver bromide membrane electrode with silver nitrate solutions and with sodium bromide solutions. Stability constants of silver(I) bromide complexes were determined using a silver ion-selective, silver sulfide membrane electrode in unsaturated solutions in which the formal concentrations of silver(I) and of bromide ranged from approximately I x 10-8 to 7 …

High School Students Achievement Of College Level Work Through The Phase Achievement System (Pas), Dwight D. Lassen

Theses and Dissertations

Senior high school students in a Human Biology course were given college level work through the Phase Achievement System (PAS), a biology course at Brigham Young University (BYU). Statistical analysis showed significant growth in high school student learning through the PAS. When ability to work with PAS was measured, significant differences between the high school and college groups were not evident. A high percentage of college and high school students dropped out of the PAS, probably becasue students could fail at the PAS without experiencing academic failure.

The Effects Of Temperature On The Oocysts Of Isospora Canis, Ray Loveless

Theses and Dissertations

Oocysts of Isospora canis, an important protozoan parasite of dogs, must sporulate in the external environment in order to become infective. To determine the tolerance of these oocysts to different temperatures, oocysts ware collected from freshly passed feces, cleaned, and subsequently stored in unsporulated, partially sporulated, and completely sporulated conditions at temperatures ranging from +50 C to -50 C. Observations on survival for each group were determined periodically thereafter at intervals up to 64 days. The rate of sporulation was followed at 6 hr intervals for temperatures of 20, 25, 30, and 38 C. Completely sporulated oocysts ware more resistant …

Biochemical Parameters Of Hereditary Chondrodysplasia In Mice, Trent D. Stephens

Theses and Dissertations

Cartilage from newborn mice homozygous for chondrodysplasia contains normal quantities of protein and chondroitin sulfate. Mutant fetal cartilage incorporates normal amounts of sulfate, glucose, and glucosamine. Overnight rinsing with water removes about 25% of the incorporated sulfur and existing uronic acid from mutant ribs and about 55% from mutant limbs. Control ribs and limbs are affected very little by such a rinse. The diffusability of chondroitin sulfate (represented by incorporated sulfur and uronic acid) may be due to a lack of covalent bond formation between chondroitin sulfate and collagen.

The Benthic Communities Of The Eastern Rocky Shore Areas Of Goshen Bay, Utah Lake, Thomas Whitney Toole

Theses and Dissertations

Information about the benthic macroinvertebrate populations along the eastern shore of Goshen Bay, Utah Lake, Utah, can be used, in part, to determine future management of the lake. In the project herein reported, cement artificial substrate samplers were used to sample two types of substrate: rubble and compacted calcareous tufa. Monthly samples were obtained from each type of substrate from March 1972 to May 1973. An amphipod, Hyalela azteca and a chironomid, Dicrotendipes fumidus were the dominant organisms in numbers and tiomass. Amphipod numbers were dependent upon the amount of algal standing crop. Elimination of this area could affect the …

Bookreviews, George A. Codding Jr.

Swiss American Historical Society Newsletter

Dear Dr. Burckhardt:

During the research for a new book on Swiss federalism, I had the occasion to renew my acquaintance with a book which has probably received far less attention among those interested in Switzerland than it perhaps should have. The book in question is William Gorhan Rice, Law Among States in Federacy: A Survey of Decisions of the Swiss Federal Tribunal in Intercantonal Controversies (Appleton, Wisconsin: C.C. Nelson Publishing Company, 1959), the writing of which was subsidized, according to the author, by the Penrose Fund of the American Philosophical Society and the University of Wisconsin.

Ecological Aspects Of Cercocarpus Montanus Raf. Communities In Central Utah, David Lee Anderson

Theses and Dissertations

Ecological and environmental aspects relating to Cercocarpus montanus Raf. Communities were investigated. Twenty study sites were sampled and described. All factors were then analyzed utilizing statistical methods. Signigicantly correlated factors to C. montanus parameters (i.e., frequency, density, cover, height) were: positive correlation--percent clay, percent clay-silt, percent litter cover, and total soluble salts in soil; negative correlation--percent silt-sand, percent sand, soil pH; exposed surface rock, Amelanchier alnifolia cover, Gotierrezia sarothrae cover and altitude. Several individual factors were singled out as being of importance in C. montanus communities; howerver, it was shown that a combination of factors was most important in determining …

Macrocyclic Polyether Sulfide Syntheses, The Preparation Of Thia-Crown-3, 4, 6, And 7 Compounds, Yau-Kwong Joseph Hui

Theses and Dissertations

Macrocyclic polyether sulfides have been prepared by reacting an oligoethylene glycol dichloride with a dithiol or sodium sulfide in ethanol. The following new compounds were prepared: 1-thia-(9-crown-3), 1,4-dithia-(9-crown-3), 1,4-dithia-(12-crown-4), 1,4,7-trithia-(12-crown-4), 1-thia-(18-crown-6), I,4-dithia-(18-crown-6), 1,7-dithia-(18-crown-6), 1,4,7-trithia-(18-crown-6), 1,7-dithia-(21-crown-7), 1,4,7-trithia-(21-crown-7). Four other previously reported macrocyclic polyether sulfides were also prepared. The symmetry of the nmr spectra of these compounds give added evidence for the proposed ring structures. The following subjects were presented and discussed: studies of cyclization by-products, dependence of cyclization yield on the size of the rings, high dilution principle and its application, medium-sized rings, effect of hetero-atoms on cyclization and melting point …

The Solution Photochemistry Of Benzaldehyde In Benzene, Ethanol, And 1-Hexyne, Ronald Douglas Knudsen

Theses and Dissertations

The photoreactions of benzaldehyde in benzene, ethanol, and 1-hexyne have been studied. Irradiation of benzaldehyde in benzene produces benzoin (I), hydrobenzoin (II), and deoxybenzoin (III). Irradiation of benzoin (I) in this solvent results in benzaldehyde formation as well as small amounts of (II) and (III). The ethanol irradiation of benzaldehyde resulted, predominantly, in the formation of (II) with (I) formed in small amounts. The photolysis of benzaldehyde in 1-hexyne produces (I), (II), (III) cis-2-heptenophenone (VII), trans-2-heptenophenone (VIII), heptanophenone (IX), and 2-(n-butyl)- 1,4-diphenyl-1,4-butanedione (X). Mechanistic pathways for the formation of these photoproducts are discussed. Separation and characterization of cis- and trans-2- …

Light And Electron Microscopy Of Resistant And Susceptible Alfalfa Roots Infected By Meloidogyne Hapla, Bernard Al Tait

Theses and Dissertations

Resistant (65-410 and 65-393) and susceptible (breeders Lahontan) alfalfa seedlings were infected with the Northern root-knot nematode, Meloidogyne hapla. Infected roots were fixed, stained, and embedded in plastic for ultrastructural investigations. Sections of plastic embedded tissue, cut at 0.5-1.5 microns for light microscopy investigations, were stained with various histochemical stains to determine the chemical composition of the nematode-altered tissues. In the susceptible cultivar, giant cells were formed by enlargement of nematode-stimulated cells without cell wall lysis. The giant cells became multinucleate by karyonkinesis without cytokinesis. Proplastids in the giant cells became structurally altered to form tubular complexes. The resistant plants …

A Calorimetric Study Of Metal Binding In Carboxypeptidase, Carbonic Anhydrase And Concanavalin A, Gary E. Hatch

Theses and Dissertations

The purpose of this study was to perfect a new calorimetric method for identifying and counting ionizable chemical groups on proteins. To do this, calorimetric and electrometric titrations were performed (using HCl and NaOH as titrant) on native carboxypeptidase, carbonic anhydrase and concanavalin A plus their apo and organic ligand bound derivatives. Readily identifiable endpoints were seen in the calorimetric titrations and general agreement was found between ΔH values obtained in this study and literature ΔH values of model compounds undergoing the same reaction. Imidazole groups were those most easily counted. Many assumptions had to be made, however, in concluding …
