Metabolism Of 3-Isopropyl-4h-2,1,3-Benzothiadiazin-4-(3h)-One-2,2-Dioxide (Bentazon) In Agitated And Non-Agitated Sediment, David Cortez Gutierrez

Theses and Dissertations

Bentazon, (3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-l-2,2-dioxide) a new experimental herbicide, was studied under the effects of sterile and non-sterile conditions, 12 hours light: 12 hours dark and totally dark conditions, and agitated and non-agitated conditions in aquatic sediment. The effects of the different levels of BOD/COD values on the decomposition of Bentazon were studied. Photoperiod, sterility, and BOD/COD levels appeared to have no influence in the breakdown of Bentazon. Agitation-time interaction appeared to be the only factor that influenced the more rapid degradation of Bentazon. Bentazon was the major 14C-residue found in the water; it was followed by an unknown. The third major metabolite …

The Attack Of Hard And Soft Nucleophiles On 6-Methylsulfonyl-, 6-Methylsulfinyl-, And 6-Methylthioaminopteridines, William David Johnston

Theses and Dissertations

In an attempt to prepare 6-anilino and 6-benzylaminopteridines, 2,4,7-triamino-6-methylsulfonyl and 2,4,7-triamino-6-methylsulfinylpteridines were prepared and reacted with a number of benzylamines and aniline. These hard nucleophiles gave amine exchange products with no displacement at the 6 position. Aliphatic amines gave exchange in the 2,4-and 7-positions. The exchange occurring in the 7-position must be occurring by an AE mechanism. This is the first such exchange reported in a ring other than a 1,3-azine. Aniline gave no exchange product except in an acid catalyzed reaction, and then gave exchange in only the 2 and 4-positions. Numerous reactions on related substrates, are reported. Soft …

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.

A Study Of Male Professional Physical Education Student Retention At The University Of North Dakota From 1970 Through 1973, Edward H. Gilroy

Theses and Dissertations

There was some concern among certain staff members of the Men's Physical Education Division at the University of North Dakota about the "disappearance" of physical education majors. The enrollment for certain junior and senior major cl*sses for the fall semester, 1973, was lower than expected and the prospects for the second semester were similar.

The HPER-107, Introduction to Physical Education,course was originally designed as a first semester freshman course for prospective majors. Most of the staff members agreed that enrollment figures for HPER-107 had been normal, or above, for the last three or four years. The question arose as to …

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- …

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 …
