The Dependence Of The Apparent Pk Of Ion Exchange Celluloses Of Ionic Strength, Paul Cyril Gillespie

Theses and Dissertations

Diethylaminoethyl cellulose was titrated with acid and base in various concentrations of NaCl. The pK values were determined from titration curves using a graphical technique. Two titratable groups were observed from the acid titration curve, a major and a minor group. The minor group, which represented 20% of the acid titration, was barely detectable in the base titration curve and had a salt-independent pK of 6.0. The pK of the major group was strongly salt-dependent and was approximately a linear function of log N NaCl. An equilibrium shift caused by the counter ion may explain the salt dependence. Hydrogen bonding …

Isolation, Purification, Scanning Electron Microscopy And Bacterial Dna Uptake Of Plant Protoplasts, Bronwyn G. Hughes

Theses and Dissertations

Protoplasts were isolated from tobacco and barley leaves in sucrose or mannitol using commercially available cellulases and macerozymes. Barley growth and protoplast isolation and purification conditions were optimized so that protoplasts were obtained in high yields free of unwanted debris and organelles. A technique for processing barley and tobacco protoplasts for examination by scanning electron microscopy was developed in which protoplasts seem to have maintained their structural integrity. Barley and tobacco protoplasts took up 3H-B. subtilis DNA, 125I-B. subtilis DNA or 125I-M. luteus DNA as a linear function of time (0-6 hr) and DNA concentration (0-200 μg/ml). Up to 16 …

Partitioning Of Space And Time By The Western Jumping Mouse, Zapus Princeps Utahensis Hall, John M. Deacon

Theses and Dissertations

Intraspecific competition is important in determining habitat utilization by members of a single species. Effective use of habitat may involve partitioning the available resources: space, time and food among individuals of different age, sex, and/or reproductive state. Numerous publications deal with interspecific competition (McCloskey and Fieldwick 1975, Cody 1973, Rosenzweig 1973, Stewart and Levin 1973, Gaby 1972, Brown 1971, Koshkina 1971, Sheppe 1967, Caldwell and Gentry 1965, Cameron 1964, Clough 1964, Gause 1932), but little has been written on intraspecific competition among populations of organisms in nature.

Cytosol Binding Of Steroid Hormones In Sheep Brains And Pituitaries, David Carl Marcusen

Theses and Dissertations

The uptake and binding of tritiated cortisol, corticosterone, and dexamethasone in cytosols isolated from various regions of non-adrenalectomized (intact) and adrenalectomized sheep brains and pituitaries were studied. [3H]-cortisol and [3H]-corticosterone were bound preferentially by cytosols from the hippocampal and septal regions of the brain, whereas, [3H]-dexamethasone was preferentially bound by cytosol from the pituitary. Cytosols isolated from the brains of adrenalectomized sheep bound significantly more [3H]-corticosterone than did cytosol from the brains of intact animals. Pre-incubation of cytosols from the hippocampus of adrenalectomized animals with non-radioactive testosterone or estradiol did not significantly block the subsequent binding of [3H]-cortisol. Results of …

Utilization Of Nest Boxes By Birds In Three Vegetational Communities With Special Reference To The American Kestrel (Falco Sparverius), Laurence Barrett Mcarthur

Theses and Dissertations

This study was designed to determine if, by providing artificial nest sites, a raptorial predator could be attracted into an area where suitable sites are limited. The American Kestrel (Falco sparverius) was a common species in the area and nest boxes designed for their use were placed in three vegetational types in western Utah and eastern Nevada. Seventy boxes were available in 1975 and 110 in 1976. Kestrels nested both years in the salt-desert shrub community but were absent from the pinyon-juniper and riparian areas. Four other bird species nested in the latter two areas, however. In 1975 the nesting …

An Analysis Of Single-Family Housing And Certain Alternatives To Alleviate The Market Depression, Jerome G. Walding

Theses and Dissertations

This study is an attempt to identify and analyze some of the reasons why the single-family housing market is in decline and whether contractors can build homes that can be affordable and yet meet demands

The findings of the study discloses why the market in 1973 was in depression by discussing both the situation of the contractors and buyers. Reasons for contractors consist of inflation in building costs, archaic building codes, and high land prices. Reasons for the buyers consist of high mortgage interest rates and high cost of ownership in relation to income. Alternatives are disclosed that some contractors …

Certain Edaphic And Biotic Factors Affecting Vegetation In The Shadscale Community Of The Kaiparowits Area, Vane Orlan Campbell

Theses and Dissertations

A study area on the southern extensions of the Great Basin cold desert (Kaiparowits Basin, Utah) was selected which has had varying amounts of disturbance. Areas with similar slope and exposure in the Shadscale community were sampled. At each site, soil samples were collected and percent sand, percent clay, percent silt, soluble salts, and hydrogen ion concentrations were measured. Cluster analysis based on percent frequency of the perennial species showed that eight groups or sub-communities were definable within the area sampled. Patterns within the vegetation were shown to be independent with the use of cluster analysis. Discriminant analysis on soil …

Gender Role Of Male Pseudohermaphrodites In The Dominican Republic, Sara V. Mallea

Theses and Dissertations

This study introduces factors in the post-pubertal change of gender role in a group of male pseudohermaphrodites in the Dominican Republic. The individuals grow up as girls because of ambiguous genitalia at birth. Upon the onset of puberty, with development of scrotum and phallus, they generally select adult male models to emulate as their future role behavior. The essay describes the socio-cultural setting in which the children are raised and proposes a theory that differential socialization of boys and girls and adult access to resources are contributing elements in the decisions to switch gender roles. At the time of the …

Mccarthyism In Utah, Richard Swanson

Theses and Dissertations

The exaggerated anti-Communist crusade of Senator Joseph McCarthy allegedly gained the support of a majority of Americans during the early 1950's. It is historically important and interesting to question that supposition by considering the character of McCarthy's following in each state. This study shows that in Utah sympathy for the second Red Scare abounded and evidences of McCarthyism were readily apparent.

Three indicators illustrate Utah's support for the Wisconsin senator. The defeat of Elbert Thomas in 1950 dramatically epitomizes the successful use of incriminating allegations effectively employed by McCarthy. The election, or re-election, of McCarthy supporters and the defeat of …

George Q. Cannon's Views On Church And State, Lyndon W. Cook Sr.

Theses and Dissertations

Writers of nineteenth century Utah generally recognize George Q. Cannon's religious and political influence as second only to that of Brigham Young. Having occupied several positions of importance in the political arena as well as in the Mormon Church, Cannon is a major figure in Utah history whose life and thought merit careful examination.

This treatise is a study of George Q. Cannon's views on the institutions of church and state. After presenting a biographical sketch of Cannon's life, it examines his beliefs regarding the religious clauses in the First Amendment, and the place of revelation, positive law, and majority …

Stratigraphy And Paleontology Of The Upper Cretaceous Morden Member (Vermilion River Formation) In The Outcrop Area, Northeastern North Dakota, Fredrick D. Wosick

Theses and Dissertations

The Late Cretaceous Morden Member is the oldest exposed bedrock unit in North Dakota, cropping out in eastern Cavalier County in the northeastern part of the state. The Morden overlies the Greenhorn Formation and underlies the Niobrara Formation. The Canadian Morden Member of the Vermilion River Formation is used in lieu of the Carlile Formation because of the lithologic similarity and proximity to the Morden type area, and the distance from the Carlile Formation type section in southeastern Colorado.

Three principal sections were measured and sampled at 2-meter intervals for microfaunal and lithologic analysis. A single well was used for …

Western North Dakota Lignite Strip Mining Processes And Resulting Subsurface Characteristics, Laramie M. Winczewski

Theses and Dissertations

Data on subsurface conditions obtained prior to strip mining is useful in planning effective mining and reclamation procedures as well as predicting the subsurface characteristics after reclamation. The redistribution of the overburden sediments is less predictable, however.

Through field observations, the major mining factors controlling subsurface structure and overburden sediment redistribution were determined. These include the geometry of the coal body, pit sequence, pit curvature, overburden thickness and managerial input. At a given location, however, the detailed structures and distribution of sediment types within a waste bank were observed to depend upon the dragline cutting pattern, distance between dragline positions, …
