Carl Bodmer: A Biographical Sketch, Hans Läng
Carl Bodmer: A Biographical Sketch, Hans Läng
Swiss American Historical Society Newsletter
Almost every illustrated work on North American Indians has pictures by Carl Bodmer, the gifted Swiss painter. Experts as well as interested laymen are impressed by his excellent portrayals of various types of Indians and their world. When we look for the artist's signature, however, we often find nothing but "after Wied" under the picture or else the name of an engraver. Thieme-Becker, Benezit, Nagel, and any number of other editors of the various encyclopedias of artists, refer to Carl Brun (Schwizerisches Kunstler-Lexikon, Frauenfeld 1905), whenever they mention Bodmer. And here, too, we find precious little information about the painter.

The Spatial Distribution Of The Nests Of The Black-Crowned Night Heron (Nycticorax Nycticorax) And The Snowy Egret (Leucophoyx Thula) In Central Utah, Randall S. Isham
Theses and Dissertations
Nests of the Black-crowned Night Heron and the Snowy Egret were examined in five central Utah colonies in 1973 to determine the spatial distribution within the colony. Nest locations of the 1085 nests of the two species were plotted to the nearest foot with an alidade and plane table. Tests of randomness, clump size, association, segregation, and T distribution were utilized. No differences between species were noted for the distance to the nearest and the next nearest nest. The Night Heron nested closer to other Night Herons and more often than did the Snowy Egret which non-significantly selected either species …

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

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
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
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 …

The Mormon Role In Irrigation Beginnings And Diffusions In The Western States: An Historical Geography, Kelly C. Harper
The Mormon Role In Irrigation Beginnings And Diffusions In The Western States: An Historical Geography, Kelly C. Harper
Theses and Dissertations
Irrigation has played an important part in the development of the Western States. Its beginnings have often been associated with the Mormon settlement in Utah. However, irrigation had its inception in the West long before the Mormons came to the Great Basin in 1847. The spatial extent of irrigation before this date included limited acreage in nearly every Western State.
Before their arrival in the Great Basin the Mormons had become acquainted with irrigation methods. Knowledge of irrigation had diffused to them primarily from the Spanish in the Southwest. Thus, they were well prepared to begin their irrigation enterprises in …

Proposal: Pioneer Venus Orbiter Mission Magnetic Field Investigation, Edward J. Smith, Leverett Davis Jr., Douglas E. Jones, Bruce T. Tsurutani
Faculty Publications
The magnetic field investigation on the Venus Orbiter Mission must provide sensitive, accurate measurements of the magnetic field at all locations along the spacecraft orbit. In addition to being able to search for and measure any weak global magnetic field that may exist, the magnetometer must have the capability of measuring fields at frequencies high enough to permit a comprehensive study of the bow shock, the region between the shock and the ionopause, the expansion fan and the wake. Accurate measurements outside the interaction region must be made in order to provide necessary information concerning the configuration of the perturbing …
Rotationally Inelastic Molecular Scattering. Computational Tests Of Some Simple Solutions Of The Strong Coupling Problem, Thomas P. Tsien, Gregory A. Parker, Russell T. Pack
Rotationally Inelastic Molecular Scattering. Computational Tests Of Some Simple Solutions Of The Strong Coupling Problem, Thomas P. Tsien, Gregory A. Parker, Russell T. Pack
Faculty Publications
Partial cross sections (opacity functions) for rotational transitions in atom-diatom collisions are computed in the infinite-order sudden (IOS) approximation and compared with accurate close-coupling (CC) calculations. Agreement is good in the dominant coupling (small total angular momentum J) region. Simple methods for calculating integral inelastic cross sections are discussed, and it is found that accurate cross sections can often be computed very simply, even when large numbers of channels are coupled together, by using IOS or first-order sudden (FOS) approximations for small J and CC or exponential Born (EBDW) methods for large J.
State Of Bacterial Dna After Uptake Into The Roots Of Germinating Barley Seeds, Larry Dale Lawson
State Of Bacterial Dna After Uptake Into The Roots Of Germinating Barley Seeds, Larry Dale Lawson
Theses and Dissertations
Germinating barley seeds have been shown to take up Bacillus subtilis DNA labelled with 5-bromouracil and tritiated thymidine and retain the DNA in the root system without substantially degrading it. The percentage of bacterial DNA recovered from the total root DNA was independent of the amount of bacterial DNA available for uptake. Four observations indicated the stability of bacterial DNA after uptake into barley roots: (1) the bacterial DNA retained its transforming ability after recovery from the roots; (2) the labelled B. subtilis DNA showed similar CsCl density gradient patterns before uptake and after uptake; (3) most of the radioactivity …

Development Of Standard Procedures For Determination Of [Delta]G° (K), [Delta]H° And [Delta]S° Values Via Potentiometric And Calorimetric Titration Techniques, Jack Hugh Ruckman
Theses and Dissertations
Standard computer techniques were developed for computation of ΔG° values from potentiometric titration data and ΔH° values from calorimetric titration data. The procedures developed can be used for any systems having the general equations HA = W^+ + A^- ; H_2A = 2H^+ + A^2- ; and H_3A = 3H^+ + A^3-, where the proton ionizations may be consecutive or simultaneous. The thermodynamic values ΔG°(K), ΔH° and ΔS° were determined for the ionization of protons from the protonated compounds methionine (-NH_3^+ group only), phosphoethanalomine and phosphoserine. The compounds studied were selected because they contain one, two and three ionizable protons …
