To write a descriptive history of the Davis County Clipper and its editors was the purpose of this study.

The first person involved with the newspaper was Lamoni Call who had been printing a small brochure to advertise his business. He asked John Stahle, Sr. to join him in printing some news along with the advertisments.

Regular publication began early in 1891 under the name of the The Little Clipper. Dissolution of the partnership came in 1894. Mr. Stahle maintained the editorial side of the newspaper his entire life. His son John Stahle, Jr. lived and loved the printing …

An Investigation Of A Mycorrhizal Association On Opuntia Polyacantha, R. Craig Stutz

Theses and Dissertations

Roots of Opuntia, polyacantha Haw. from Juab County, Utah were found to be nodulated. An anatomical study of the nodulated roots showed them to be ectotrophic mycorrhizae. Fusarium poae (Peck) Wollenweaver was found associated with the nodules both as an epiphyte and an endophyte. However, reinfection with this organism failed to induce subsequent nodulation. Under certain conditions the roots of o. polyacantha are able to overcome the mycorrhizal infection and elongate. It is not uncommon for several branch roots to originate from a single nodule. It is suggested that the fungus-root association found in o. polyacantha represents an early stage …

A Tone Signature Analysis Of Multispectral Photography, Michael V. Miller

Theses and Dissertations

Densitometrie analysis of separation negatives, Ektachrome and Infrared Ektachrorae film was performed to determine the tone signature from the films and to compare the respective tone signatures for reliability and use.

Three types of vegetation, coniferous and deciduous trees and grass, were used as targets for all the photography in this study.

The analysis and comparison of data used in this investigation revealed that density fluctuations within a specific spectrum band of a particular target were too great to yield a reliable and identifiable tone signature.

Analysis of the data revealed that the density differences between adjacent spectral bands remain …

A Histochemical And Fine Structural Study Of Extracellular Fibrils In The Developing Chick Embryo, James J. O'Connell

Theses and Dissertations

The histochemistry of developing connective tissues and its relation to early connective tissue fibrils was investigated in the chick embryo. An area well suited to correlated histochemical and electron microscopic study occurs around the notochord. Here early microfibrils later contribute to the cartilaginous model of the future vertebral body. Chick embryos were sacrificed at one, two, three, four, six and ten days of incubation and were prepared routinely for both light and electron microscopy. A series of five histochemical stains (PAS, alcian blue, Hale colloidal iron, metachromatic toluidine blue, methenamine silver) and two histological techniques (Mallory's connective tissue; Weigert's elastin) …

Ultrastructural Investigations Of Tilletia Caries Teliospores, James Vincent Allen

Theses and Dissertations

The purpose of this study was to investigate the ultrastructure of Tilletia caries teliospores. Specimens were prepared for viewing in the electron microscope by freeze-etching and thin-sectioning techniques. Thin-sectioning techniques gave excellent results with the teliospore walls and the lipid bodies within the teliospore but failed to adequately fix the membranes and internal organelle systems. Micrographs of Tilletia caries teliospores prepared using thin-sectioning show three major wall layers and two partition wall layers and abundant lipid bodies. The freeze-etch method of spore preparation proved superior to the thin-sectioning used in this study to reveal the internal organelle systems of the …

The Effect Of Chemical Adjuvants Of The Survival Of The Free-Living Stages Of The Gastrointestinal Nematode, Haemonchus Contortus, Anthony T. Chang

Theses and Dissertations

Considerable research has been done on the influence of various chemical adjuvants, such as glycerol and dimethyl sulfoxide (DMSO) on the survival of protozoan organisms. (Levine and Marquardt, 1955; Levine, Mizell and Houlahan, 1958; Levine, et al. 1962; Levine and Andersen, 1965, 1966; Fitzgerald and Levine 1957 1 1961; Diamond, 1964). Considerably less work has been done on metazoan parasites. The effects of various chemical adjuvants on the survival of Haemonchus contortus, the large stomach worm of sheep, at extremely low temperatures has not been reported. The purpose of this research was to determine if different concentrations of chemical adjuvants …

Surface Characteristics Of Conidia From Monosporous Cultures Of Penicillium Digitatum And Aspergillus Nidulans Var. Echinulatus, Raymond Kunito Fuji

Theses and Dissertations

The purpose of this investigation was to evaluate the possible taxonomic significance of the "rodlet" patterns and spore wall configurations of conidia from monosporous cultures of Penicillium digitatum Saccardo and Aspergillus nidulans Eidam var. echinulatus Fennell & Raper. Freeze-etching the conidiospores from single spore isolates of these fungi revealed that spore wall patterns and configurations vary much too greatly to be of taxonomic importance on the strain and subspecies level. Environmental factors and genetic influences are discussed as possible mechanisms causing the variations of the spore wall configurations. A membrane-like structure that covers the "rodlet" patterns and which hinders spore …

Comparative Effects Of Carbon Dioxide On Coccidian Oocysts From Five Different Host Species, Thomas David Bunch

Theses and Dissertations

Excystation, as applied to the coccidia, is the process by which sporozoites are released from sporocysts and oocysts. Although this process has long been a subject of interest and study, there still remains considerable disagreement among investigators as to the mechanism by which the process occurs and the factors which are involved.

Syntheses Via Modifications Of The Knorr-Paal Procedure :|Ba. Derivatives Of 2,6-Dioxa-10-Azatricyclo[5.2.1.0[Superscript 4,10]]Decane ; B. Highly Sterically Crowded 1,2,5-Trialkylpyrroles And Pyrrolidines, Weldron Severin Burnham

Theses and Dissertations

Earlier work in these laboratories on the heterotricyclic system 2,6-dioxa-10-azatricyclo[5.2.1.04,10]-decane, formed from 1,4-diketones and 2-amino-1,3-propanediols by a product-water-azeotroping procedure, was extended with the synthesis of analogous compounds, e.g., the 1,4,7-triethyl-, 1,7-dimethyl-4-isopropyl-1,7-diethyl-4-isopropyl-, 1,7-dimethyl-3- and 4-phenyl- compounds. The 1,7-dimethyl heterotricycle, the kinetically-controlled product, was accompanied by the thermodynamically-controlled product, 2-(2,5-dimethyl-1-pyrryl)-1,3-propanediol. The 1,7-diethyl heterotricycle was also accompanied by the isomeric pyrrole as were the 1,7-dimethyl-3- and 4-phenyl compounds. A scheme postulating a common intermediate is presented. The interesting analogous compounds, 1,7-dimethyl-2-oxa-6-thia-10-azatricyclo[5.2.1.04,10]decane, 1,4,7-trimethyl-2,6-dioxa-11-azatricyclo[5.3.1.04,11]undecane and 11-hydroxymethyl- and 11-methyl-9,13-dioxa-14- azatetracyclo[6.5.1.02,7 011,14]tetradeca-2,4,6-triene were also prepared. The syntheses in good yields of a considerable number of moderately to …

A Comparative Survey Of Soil Microfungi From Three Vegetation Types In Cedar Valley, Utah, Brent T. Wahlquist

Theses and Dissertations

Microfungi were isolated from soil samples by the soil plate method. Soil samples were collected at depths of 0-1", 1-4", and 4-8" both between and beneath the canopy of the dominant vegetation in stands of greasewood, sagebrush, and pinyon-juniper. Salinity, pH, and percent organic matter were measured for each soil sample. A total of 148 strains of fungi representing 141 species and 46 genera were isolated and identified from these alkaline soils, Few strains, including some Aspergilli, occurred only in the more saline greasewood soils, while many strains, including several Penicillia, occurred in both sagebrush and piny-on-juniper soils but were …

Rheological Study Of Concentrated Silica Suspensions, Prakash N. Mishra

Theses and Dissertations

Concentrated suspensions of silica in water were investigated using a rotational viscometer and a Zeta-Meter. The viscometric data was analyzed for shear dependence, solid concentration dependence and pH dependence. The data for electrophoretic mobility was analyzed for pH dependence.

The experimental data was applied to the Bingham plastic model and the power law model and the power law model was found to describe the experimental data more closely than the Bingham plastic model. The parameters for these two models were correlated to solids concentration, pH and electrophoretic mobility.

Effect of particle size on apparent viscosity was also studied but no …

The Use Made By Lds Institute Instructors Of Statements And Messages Of The Modern Prophets In Answering Current Issues Of Importance To College Students, Gale J. Brimhall

Theses and Dissertations

This study was designed to evaluate the L.D.S. institute instructors use of statements made by leaders of the Church of Jesus Christ of Latter-day Saints. These leaders have instructed Church school teachers to teach what the prophets have said and not the teachers own ideas or views on doctrine.

The data from this study show the following: (1) Approximately twenty per cent of instructor responses in selecting the stated principles of the Church on a current issue are incorrect; (2) The ability of the instructors to recognize prophet's statements from non-prophet's statements is seventy-three per cent; (3) Over ninty per …

George Romney In 1968, From Front-Runner To Drop-Out, An Analysis Of Cause, Richard M. Eyre

Theses and Dissertations

The meteoric political decline of George Romney is unparalleled in political history and in the history of presidential campaigning. In the space of one year, the man evolved from the overwhelming presidential favorite of Republicans, Democrats, and Independents alike to a presidential drop out, criticized severely and even mocked by press and public alike.

There are many opinions as to why this phenomenon occurred. The press has opinions, the public has opinions, and the people closest to George Romney have opinions.

A step by step analysis of Romney's campaign casts light on these opinions and completely discredits some while validating …
