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 …

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 …

A Concept Of Buoyancy In Topological Spaces, With Applications To The Foundations Of Real Variables, Elwyn David Cutler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Buoyancy Theorem states that a compact set is buoyant if every point of the compact set has a neighborhood whose intersection with the compact set is buoyant. In this paper, the Buoyancy Theorem is used to prove several standard results involving compact sets. The proof of such a result may be a direct application of the Buoyancy Theorem or the proof may rely on a certain compactness argument which follows from the Buoyancy Theorem. The last application in this paper is such an example.

The method used is to, first of all, define a buoyancy on the compact set; …

Analysis Of Contingency Tables, James Joseph Biundo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two methods of analyzing multi-dimensional frequency data are detailed.

The Second Order Exponential (SOE) model is applicable for dichotomous classifications. The distribution has two sets of parameters, ϴ_i's and ϴ_j's. The ϴ_i's are interpreted as the log of the odds of the marginal probabilities if no two factor relationships exist. Or if all ϴ_ij are not zero, then the ϴ_i's are analogous to a main effect in a 2^m factorial analysis, (m = number of factors or classifications). The ϴ_if's may be interpreted as a measure and direction …

Generation Of Random Numbers, Keith H. Eberhard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Subroutines are written to generate random numbers on the computer. Depending on the subroutine used, the generated random numbers follow the uniform, binomial, normal, chi-square, t, F, or gamma distribution. Each subroutine is tested using the chi-square goodness of fit test to verify that the random numbers generated by each subroutine follow the statistical distribution for which it is written. The interpretation of the test results indicates that each subroutine generates random numbers which closely approximates the theoretical distribution for which it is designed.

The approach used in the subroutine which generates gamma distributed random numbers involves the use of …

A Study Of Evaporation And Evapotranspiration In Peru, Fernando Chanduvi-Acuña

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twenty-four equations for estimating evaporation and/or evapotranspiration were compared with measured Piche evaporation. At least 1728 months of records from 12 Peruvian stations were analyzed in this study.

Computer programs were developed to work this study and the results were compared by plotting.

It has been found that the equation that best fits the Piche evaporation in the low elevation stations in Peru is Christiansen's formula (ET2) which was used as a base for his formula for Class A pan evaporation (EVC).

Factors Affecting Mourning Dove Use Of Water In Artificial Catchment Basins In A Dryland Farming Area Of Utah, Norman A. Slade

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mourning dove population of the Howell-Blue Creek Watershed in northern Utah was studied by Norman Slade in an effort to determine why many more doves frequented certain of the 20 fiberglass catchment basins installed in the area.

More doves used basins on the west side of the valley, probably as a result of temperature differences. More doves used those basins surrounded by more land in summer fallow and with fewer basins nearby. Areas in sagebrush were used for nesting.

The number of doves drinking in a particular hour was affected by the presence of predators or antagonists but not …

A Study Of A Community In The Process Of Withdrawing A Service, Emma Lois Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1942, the Navy Department constructed a Naval Supply Depot at Clearfield, Utah. The northern part of Davis County was still in the grips of the Depression of the 1930's. Therefore, the Public Housing Administration constructed a temporary housing unit of cinderblocks under the authorization of the Lehman Act of 1940 for those who came to the Clearfield area for employment. It was named Anchorage. In 1955, the Federal Government sold Anchorage to Clearfield City for $20,451.70.

Clearfield City hired a crew of three men to maintain the project. The maintenance of the project slowly deteriorated through the years. Major …

Dietary Factors And Induction Of Hepatic Microsomal Hydroxylative Enzymes By Organochlorine Pesticides, D. Jesse Wagstaff

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Induction of hepatic microsomal hydroxylative enzymes is an important aspect of detoxication of fat-soluble toxicants. The magnitude of induction depends on numerous factors, such as the nature and dose of toxicant as well as dietary factors. Research was conducted on (1) endrin tolerance in rats, (2) preliminary comparisons of inductive effects of various organochlorine pesticides in rats to select compounds for further study in guinea pigs, (3) general effects of various dietary factors on induction, and (4) effects of ascorbic acid deficiency on induction of hepatic microsomal hydroxylative enzymes by organochlorine pesticides in guinea pigs. Measurements were made of body …

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 …

Analysis Of Long-Term Streamflow Patterns On Two Davis County Experimental Watersheds In Utah, Stephen P. Glasser

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The influence of aspect on water yield variability over a long period, 1936-1964, was studied at two small, mountainous watersheds within the Davis County Experimental Watershed near Farmington, Utah.

North-facing Miller Creek is densely vegetated by a conifer-aspen forest and mountain brush. Miller Creek's yield was more variable for daily, monthly, seasonal, and annual flows than yields from south-west facing Halfway Creek which is covered by mountain brush. Differences between watersheds in annual yield and snowmelt season runoff were nonsignificant.

The snowmelt runoff season extended for an average of 65 days on both watersheds, but it began 24 days earlier …

A Study Of Precipitation Characteristics For Utah, Tsing-Yuan Chang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Data on monthly precipitation for three areas of Southern Utah--Beaver, Cedar City and Ephraim--and three areas of Northern Utah--Salt Lake City, Ogden and Logan--where a series of measuring stations were arranged as traverses from the valleys to the mountain tops; were assembled and analyzed.

The relationships between elevation and precipitation amounts were shown. The Southern Utah stations were drier at the same elevations than the Northern Utah stations and the differences became greater as the elevations increased. There was a close correlation between the high elevation and low elevation stations in the same traverse even with the above divergence.

Salinity And Water Potential Sensor For Evaluation Of Soil Water Quality, Melvin Dee Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective of this study was to evaluate response times of a salinity sensor and a soil psychrometer. Influences of pressure, temperature and molar concentration changes were to be measured.

Salinity sensor response times ranged from 50 to 130 minutes during solution adsorption while desorption response times were perhaps ten times as long. Temperature affected both response times and equilibrium values, but pressure did not affect either.

Soil psychrometer response times ranged from from 40 to 80 minutes for either adsorption or desorption of solution. However, other factors probably related to indirectness of measurement made the soil psychrometer fail to …

Quantitative Evaluation Of Saponin Content In Du Puits Alfalfa Foliage (Medicago Sativa L.) With Trichoderma, Wang Li-Chun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Selections in Du Puits alfalfa (Medicago sativa L. ) were evaluated for saponin content. The data obtained from the Trichoderma bioassay were converted to saponin values by regressions and standard curves. It was necessary to adjust the concentration of alfalfa extract in the bioassay so that the saponin content in alfalfa was estimated in that portion of the curve showing a marked response to saponin. A different regression was established for each group of low and high saponin plants of Du Puits alfalfa. The standard curve prepared with extract of Du Puits alfalfa used on the basis of its …

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 …
