The Desert Bighorn Sheep Of Southeastern Utah, Charles A. Irvine

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In April, 1967, this study was begun in a 211-square-mile area, in the rugged, arid, Red Canyon area in San Juan County, southeastern Utah. Sixteen months were spent in the field to determine the population trend, migration, distribution, and the affect of water on distribution of the bighorn sheep.

No migration was documented, but seasonal shifts did occur. The shifts were due to the availability of water in the free state and in plants. Dry periods forced sheep to remain close to seeps and springs.

Lambing peaked in May and was over by June. Lou lamb mortality and high numbers …

The substrate was made by reconstituting 6 g NDM in 500 ml of buffer containing 0.2 M CaCl₂, 0.5 M cacodylic acid and 0.2 M triethanolamine at pH 5.7. Cheese curd was blended into a 1:7 slurry (1 part curd, 7 parts water), and 1.67% sodium chloride was added to the whey and slurry to liberate residual rennin from casein. The residual rennin in cheese whey and slurry were determined simultaneously with an identical sample containing known rennin activity. Samples with known activity …

Role Of Lamb Pregastric And Gastric Extracts In Cheese Manufacture, Ramjibhai V. Chaudhari

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lamb pregastric (PGE) and gastric extracts (GE) have been evaluated for their role in Italian cheese flavor production. Both have been shown to produce increases in free fatty acids and in non-protein-nitrogen during incubation with milkfat and casein substrates as well as in cheese substrates. Gastric lipase and cathepsins are considered to be the additional active agents in GE. Parmesan cheese manufactured with PGE and GE added to the curd was superior in flavor when both were employed, and either extract alone was better than the uninoculated control. An assay for GE proteolytic activity has been proposed which involves the …

Environmental Analysis Of The Swan Peak Formation In The Bear River Range, North-Central Utah And Southeastern Idaho, Philip L. Vandorston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Swan Peak Formation in the Bear River Range of northern Utah and southeastern Idaho varies in thickness from 0 feet to over 400 feet. It consists of three units: (1) a lower unit of interbedded quartzites, shales, and limestones; (2) A middle unit of interbedded quartzites and shales; (3) An upper unit of nearly homogeneous quartzites. The different sedimentary structures, ichnofossils, body fossils, and mineral compositions of each unit represent different environments of deposition. The lower unit probably was deposited in a shallow-shelf environment, and its sediments grade upward into probably shoreface-, tidal-flat-, and lagoonal deposits of the middle …

Brisket Disease: Influence Of Hypoxia And An Induced Calcium-Potassium Imbalance On The Mineral Composition Of Blood, Heart, Liver, Kidney, And Bone, David Eugene Bailey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Brisket disease, an affliction of cattle, is important because of: (1) economic losses, (2) similarities to chronic mountain sickness in humans, and (3) the provision of experimental animals for cardiac research. In afflicted cattle, right cardiac ventricular hypertrophy and dilatation occur and are manifestations of attempted compensation for reduced alveolar oxygen by increasing pulmonary circulation.

Geographic variations in occurrence of brisket disease in Utah indicate that hypoxia is not the sole causative factor. From the findings that afflicted cattle exhibit hypocalcemia and hyperkalemia, and the disease occurs most commonly in wet meadowland environments where potassium is high and calcium low …

Ogden's Notorious "Two-Bit Street," 1870-1954, Lyle J. Barnes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A history which records the weaknesses and failures of society may serve as its conscience. The history of Twenty-fifth Street in Ogden, Utah is that kind of history. It reminds us that it is possible for evil influences to prey upon society to the extent that it weakens and becomes vulnerable to the influence.

First the people became passive. They began to feel that the influence was there and there was little they could do about it. They then began ignoring it as if by doing so it would cease to exist. But it didn't disappear. Instead it grew and …

Improvements In The Biological Assay Of Tobacco Mosaic Virus, Calvin Ray Lamborn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bean plants which were most susceptible to tobacco mosaic virus (TMV) were selected from more than 1,000 plant introductions. Thirty-eight percent of the lines tested developed local lesions, an indication of susceptibility to TMV. Six percent were better local lesion hosts than the commonly used bean variety (Pinto). Some lines were nine times more susceptible than the variety Pinto. Selections from P. I. 164353, 165455, 273673, 227379 and 223006 appeared to be the best local lesion hosts. A selection from P. I. 223006 produced lesions which were larger, lighter in color and slower developing than those of any other line …

The Alkaloids Of Delphinium Occidentale S. Wats., Lester B. Kreps

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Total and individual alkaloids were determined for duncecap larkspur from emergence through seed production. Total alkaloids were determined by a titration method. Individual alkaloids were separated by thin-layer chromatography and determinations made by cochromatography.

Total alkaloid concentration was highest during early vegetative growth then decreased steadily throughout the season. Decrease in total alkaloids was specific for a certain plant part. Total alakloids in stems and petioles declined more rapidly in the spring than did alkaloids in the apexes and leaves. Seasonal decline of total alkaloid was not noted in the crowns and roots; alkaloid concentration remained constant throughout the year …

Gas Chromatographic Determination Of Changes In Concentration Of Pipecolic Acid And Other Free Amino Acids In Hypersensitive Tobacco Plants Induced By Tobacco Mosaic Virus And Temperature, David Francis Brown

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Changes in concentrations of pipecolic acid and other free amino acids in Nicotiana tabacum, L. cv. Xanthi induced by tobacco mosaic virus (TMV) incubated at 75 or 95 F after inoculation were investigated gas chromatographically. A preliminary extraction and gas chromatographic technique for separation and quantitative determination of the free amino acids, using hydroxyproline as an internal standard, was developed.

Amino acids were converted into their trifluoroacetyl n-butyl (TAB) derivatives and gas chromatographed on 0.325 percent ethylene glycol adipate (EGA) columns. Resolution was generally good, but glycine-isoleucine and phenylalanine-aspartic acids were not resolved on old columns. The over-all …

The Social Organization Of Wild Turkeys On The Welder Wildlife Refuge, Texas, Charles Robert Watts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is of the social organization of the wild turkey (Meleagris gallopavo intermedia Sennett) on the Welder Wildlife Refuge in southern Texas.

The earliest turkey nests hatched in April, with the peak of hatching a month or more later. These poults may remain with their mother until winter. This brood flock, however, often combined with other brood flocks to form composite brood flocks when the poults were a few weeks old. Hens not successful in rearing young combined into broodless flocks.

The juvenile males left the brood flocks in late fall or winter. They remained a distinct unit, …

Area Agricultural Outlook And Adjustment Conferences, N. K. Roberts, L. A. Clement, D. B. Nielsen, R. A. Christensen

Economic Research Institute Study Papers

We live in a dynamic world, and whether or not changes are "good" for an individual or a group of people depends upon their ability to use them to an advantage. In some parts of the world farmers and ranchers are just as up-to-date in their methods at the close of their productive life as they were at the beginning because nothing has changed. The same was true in America for our grandfathers. It is not true anymore. Now days man's management ability can become "obsolete" three or four times during his productive life if he does not change with …
