Determining Market Areas For Livestock Grazing, Robert G. Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Differentials between rancher costs of operating on private and public range were studied in an attempt to define market areas for livestock grazing in western United States.

The problem of defining market areas is basically a problem of grouping differentials between rancher costs of grazing on private leased range and National Forests that are reasonably homogeneous and statistically testing differences among means of the different groups.

Several methods were used to group forests with reasonably uniform differentials into market areas for cattle. A grouping of forests which have the same average grazing fee does not, however, yield market areas which …

A Method For Plotting Isohyetal Maps Using An Analog Computer, Maurice George Kirwan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ability of the analog computer to stimulate physical phenomena is used in conjunction with a resistance paper model of the Walnut Gulch watershed in Arizona to plot constant precipitation maps from data obtained from recorded rainfall. Voltages which are proportional to rainfall at a specific raingage, located at scaled points of the resistance paper model, set up an electric field on the resistive sheet which is detected and processed by the computer. The detected potential is compared to a reference potential, or "precipitation value", and the necessary analog networks allow plotting of the equipotential line which is directly analogous …

Waterfowl Production On A Spring-Fed Salt Marsh In Utah, Donald E. Mcknight

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Results of past studies on the spring-fed salt marshes of Utah indicated that waterfowl production on these areas was much lower than on Utah's river-fed marshes. Waterfowl production on the newly-established Fish Springs National Wildlife Refuge, a spring-fed marsh, increased considerably, however, after its waters were impounded. It was believed that by determining what caused this increased production at Fish Springs it would be possible to obtain greater waterfowl production at other spring-fed marshes. Consequently waterfowl populations and factors affecting waterfowl production on this marsh were studied during the summers of 1966, 1967, and 1968.

Populations of breeding ducks averaged …

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 …

Implications Of Tort Liability In Utah And Physical Educators Understanding Of Their Liability, Eldon C. Louder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Utah Tort Liability law was defined and a teacher understanding of the law and their liability was determined.

Physical Education teachers do not have a good knowledge of the state's liability law, nor are they aware of the liability they are open to.

Where opportunity was afforded, teachers were anxious to place the responsibility for their actions on someone of a higher position. This could be attributed to the fact that district and state administrators have not made an awareness of our new law.

The area of liability least understood is inadequate use of professional knowledge and skills. Sending …

Methods Of Correcting Iron And Zinc Deficiencies In Peach Trees, Earl Seeley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Studies were conducted to determine the effects of iron and zinc chelates on these deficiencies. Soil treatments, and foliar treatments with and without urea were used. It was found that in soil treatments at least one pound chelate per tree must be used to significantly increase the iron content of the leaves. The soil treatments did not result in as high a concentration in the leaves early in the season, but they had a residual effect that lasted throughout the entire growing season. Foliar treatments with iron did not effect the foliage that developed after the final application was made. …
