Properties Of Model Transition Metal Complexes In The 1,4-Diene Rearrangement, Richard D. Stauffer
Properties Of Model Transition Metal Complexes In The 1,4-Diene Rearrangement, Richard D. Stauffer
Theses and Dissertations
The properties of model transition metal complexes in the skeletal rearrangements of some 1,4-dienes catalyzed by a mixture of dichlorobis (tri-n-butylphosphine) nickel(II) and diisobutylaluminum chloride have been examined. These rearrangements are exemplified by the skeletal isomerizations of cis-1,4-hexadiene, the type I rearrangment (equation 1) and 3-methyl-1,4-pentadiene, the type II rearrangement (equation 2). The active catalyst species in the type I rearrangement has been limited to the nickel component since coordinately unsaturated ethylenebis (tri-o-tolylphosphite)-nickel(0) on combination with HCl skeletally rearranges cis-1,4-hexadiene to the type I product, trans-2-methyl-1,3-pentadiene. This catalyst combination also produces the double bond isomerization products trans, cis- and cis, …

4. What criteria was used in …
Effects Of Repression-Sensitization, Arousal, And Sex On Physical Aggression, Richard J. Moser
Effects Of Repression-Sensitization, Arousal, And Sex On Physical Aggression, Richard J. Moser
Theses and Dissertations
In the past two decades, numerous experiments have focused on a wide variety of situational factors influencing the arousal, intensity, and direction of aggressive behavior. In contrast, few studies have considered the role of individual difference variables in producing aggression. The present study was concerned with a personality variable which theoretically should have some relevance to the expression of physical aggression. This variable was repression-sensitization (R-S) as measured'by the revised Repress ion-Sensitization Scale (Byrne, Barry, and Nelson, 1963). In an attempt to improve upon the predictive validity of R-S, defensive and nondefensive repressors were differentiated through the use of Marlowe-Crowne …
A Historical Development Of Pooling Of Interest, Jim Oleson
A Historical Development Of Pooling Of Interest, Jim Oleson
Theses and Dissertations
The term "pooling of interests" was first used by the AI CPA in a report issued in 1945 by the Committee on Public Utility Accounting. Since that time, the pooling of interests concept went through much debated change and revision
The Accounting Principles Board issued their first opinion on pooling of interests in Accounting Research Bulletin Forty. This bulletin was followed by three more. During this time the criteria proposed in these bulletins as a basis for classifying a business combination as a pooling of interests were being constantly modified. Many of the changes began to liberalize the accounting treatment …

A New Method For The Preparation Of Alkylnaphthyl Ethers And Sulfides, Edward Ying-Shih Chen
A New Method For The Preparation Of Alkylnaphthyl Ethers And Sulfides, Edward Ying-Shih Chen
Theses and Dissertations
The reaction of monohalonaphthalenes with metal alkoxides and mercaptides in a solvent mixture of the corresponding alcohol and dimethyl sulfoxide (DMSO) has been studied. These reactions are convenient methods for the preparation of alkylnaphthyl ethers and sulfides. Only direct nucleophilic substitution was observed in the reactions of bromonaphthalenes with sodium methoxide and sodium nbutyl mercaptide. The reaction of fluoronaphthalene with potassium t-butoxide also proceeded by way of direct nucleophilic substitution rather than the 1,2-dehydronaphthalene intermediate as in the reactions of bromonaphthalene with potassium t-butoxide. The use of a base which is weaker than t-butoxide can change the apparent reaction mechanism …
Rhenium Catalyzed Hydrogenation Of Maleic Anhydride And Crotonaldehyde, William Russel Dixon
Rhenium Catalyzed Hydrogenation Of Maleic Anhydride And Crotonaldehyde, William Russel Dixon
Theses and Dissertations
The preparation of a number of supported rhenium catalysts is reported. The determination of their activity and selectivity and of optimal reaction parameters for the reduction of maleic anhydride and crotonaldehyde is reported. Optimal time of hydrogenation was chosen as one hour and pressures were chosen as 2000 psig for crotonaldehyde and 3000 psig for maleic anhydride. Quantitative reduction of maleic anhydride to tetrahydrofuran occurred at 275° with charcoal supported rhenium catalysts. Lower temperatures (ca. 200°) produce quantitative amounts of butyrolactone. Unsupported catalysts at low temperatures (100°) selectively reduce crotonaldehyde to crotyl alcohol, but at very low conversion rates. Temperatures …
The Reproductive Biology Of The Leech Helobdella Stagnalis (Linnaeus) In Utah Lake, David L. Tillman
The Reproductive Biology Of The Leech Helobdella Stagnalis (Linnaeus) In Utah Lake, David L. Tillman
Theses and Dissertations
The reproductive biology of the brooding leech Helobdella stagnalis (Linnaeus) in Utah Lake was studied for an 18 month period from June 1970 to December 1971. In determining the annual reproductive cycle, the number of adult leeches carrying eggs or young were counted at weekly intervals during the reproductive season and monthly during the rest of the year. Gonadal staging data from histological sections were correlated with the field collection data. It was found that two broods of young were produced by the adult animals during the reproductive season. Continuous water temperatures were recorded at the study site throughout the …
Toward Hydrogen Bonds Of Predictable Geometry, Robert Shao-Chih Hsu
Toward Hydrogen Bonds Of Predictable Geometry, Robert Shao-Chih Hsu
Theses and Dissertations
A literature review on the geometry of hydrogen bonding showed that the geometry is often de-emphasized or even ignored, probably because of the inherent flexibility of many systems studied. Examination of molecular models suggested the geometrically constrained bicyclo [2, 2, 1] heptane system wherein hydrogen bond distances and angles might be more easily predicted. Dihydroboration-oxidation of norbornadiene was shown to yield exo, exo-2,5-norbornadiol, thus clarifying uncertainties in the literature. 2, 5-Norbornadiol was oxidized to the corresponding dione, heretofore inadequately characterized. Several derivatives of the dione were prepared, and spectral data were accumulated for the dione, its precursor, and its derivatives. …

Vegetation Changes Following Fire In The Pinyon-Juniper Type Of West Central Utah, Milo Arnel Barney
Theses and Dissertations
A total of 28 burn areas, that varied in age from 3-100+- years, were analyzed in a study of succession following fire, in the pin yon-juniper woodlands of west central Utah. Data were collected by means of the line-point and quadrat methods. These data were subjected to a multiple regression analysis. Canopy cover, basal area (sq. ft./acre) and density (trees/acre) of juniper were highly correlated with age of burn. Percentage dead sagebrush was found to be positively correlated with density of junipers. The stages of succession following fire began with weedy annuals, that reached a peak within 3-4 years. Juniper …

Fort Berthold Indian Reservation: A Land Use Study To 1971, Paul Felter
Theses and Dissertations
Can the land resources of a contemporary Indian reservation provide the basis for a self~sufficient community? To help answer that question, this study traces the agricultural development as well as other land use programs and problems of the Three Tribes of the Fort Berthold Indian Reservation in North Dakota.
The procedure involved a detailed study of the impact of Bureau of Indian Affairs-inspired agricultural projects, treaties and land cession agreements, land allotment programs, land fractionalization, and the building of the Garrison Dam. The results obtained show that the semi-agricultural Three Tribes passed from self-sufficiency before their reservation was established into …

A Taxonomic Study Of The Western Collared Lizard (Crotaphytus Collaris), Nathan M. Smith
Theses and Dissertations
The marked pattern and coloration which distinguish members of Crotaphytus collaris baileyi in its western range indicated a need to compare it to the collaris-complex consisting of C.c. auriceps, C.c. baileyi, and C.c. fuscus. Thirty-two external and sixteen cranial characters were measured on preserved specimens. Blood serum proteins were compared by disc gel electrophoresis. Cluster, canonical, and discriminant analyses were used to define population characteristics and areas of intergradation. Disc electrophoresis did not reveal consistent population differences. The western range of C.c. baileyi is restricted to Central Arizona. The Great Basin form from western Arizona, western Utah, southern Idaho, southeastern …
Synthesis And Metal Coordination Properties Of Some Cyclic Polyethers And Polythioethers, Barry Lant Haymore
Synthesis And Metal Coordination Properties Of Some Cyclic Polyethers And Polythioethers, Barry Lant Haymore
Theses and Dissertations
Thermodynamic values for cation-cyclic polyether interactions for several systems are reported and discussed in light of ligand geometry, cation selectivity, solvent effects, structure, stoichiometry and the nature of the coordinate bond. Cyclic polyethers are shown to be remarkably good ligands even in water and to have marked selectivity for d0, d10 and d10 s2 cations. Syntheses of one new cyclic polyether and several new mixed cyclic polyether-thioethers are reported. Cyclic chelates with smaller rings are shown to prefer smaller cations, but this selectivity is masked by the hydration energy of the cation. Except for thiophillic cations such as Hg2+ and …
Enzymatic Synthesis Of Oligoribonucleotides Of Defined Base Sequence, Mark J. Rowe
Enzymatic Synthesis Of Oligoribonucleotides Of Defined Base Sequence, Mark J. Rowe
Theses and Dissertations
The synthetic reaction of ribonuclease T_1 has been studied as to its potential for the synthesis of oligoribonucleotides of defined base sequence. Conditions have been determined for maximum synthesis with respect to percentage incorporation of both guanosine 2',3'-cyclic phosphate (donor), and cytidine (acceptor). With regard to maximum acceptor incorporation, a donor blocked at the 5'-hydroxyl has been used to drive the reaction. It has also been shown that acceptor incorporation decreases as the chain-length increases up to the hexanucleotide. Synthesis of a 3'-blocked substrate for polynucleotide phosphorylase for use in chain termination studies was attempted using adenylate kinase. In this …

Analysis Of Asexual Reproduction Dugesia Dorotocephala, Harvey Dee Mecham
Analysis Of Asexual Reproduction Dugesia Dorotocephala, Harvey Dee Mecham
Theses and Dissertations
Genetic control of decapitation-induced fission in planaria is mediated by stimulator and inhibitor molecules. Resolution of the two factors was accomplished by filtration chromatography of whole planaria extract. The stimulator (M.W. 2500 to 3500) was purified with ion exchange chromatography and increases the multiple fission rate. The inhibitor (M.W. 20,000 to 50,000) is non-dialyzable, heat labile and is inactivated unless kept frozen. Storage at 4°C results in a loss of inhibitory capacity with a concomitant stimulator increase, suggesting a protein-stimulator complex as the inhibitor. In light of a demonstrated animal intercommunication system, the inhibitor-stimulator complex is hypothesized as part of …
