The Anatomical And Morphological Effects Of Dcpa On Seedlings Of Selected Species Of Plants, Bijan Shaybany

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Seeds of oat, green foxtail, squash and tomato were germinated in soil treated with different levels of DCPA (dimethyl 2, 3, 5, 6-tetrachlorote-rephthalate). The concentrations used varied according to the sensitivity of the plants to the chemical.

The response of oat and foxtail to DCPA was similar. The growth of booth root and shoot was reduced. This reduction was directly related to the concentration of DCPA. Anatomical studies showed that cells in the shoot and root meristems of treated plants were completely disarranged and that some of the cells of these regions were hypertrophied. Some clumping of nuclei was observed …

The Teaching Of Performance Techniques For Cornet And Trumpet, Sterling J. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of the basic performance techniques used by cornet and trumpet specialists and the common problems encountered by cornet and trumpet players was made through reference to personal experience, personal interviews, and articles in journals, magazines, bulletins, and books.

Three areas of performance were studied: (1) tone production, (2) intonation, and (3) technical development.

It was found that there is usually more than one solution to a problem, and that each solution given must be individualized to meet each player's needs. Most of the problems players encounter can be prevented if one uses correct playing procedures while playing a …

Quality Of Beef Roasts: Electronic Versus Conventional Cooking, Frances Glassett Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of breed, backfat thickness, and methods of cooking on quality of beef roasts was determined by sensory and objective methods. Arm and rib roasts from Hereford, Shorthorn, Charolais, and Shorthorn-Charolais animals were cooked by several methods.

Roasts of the ninth to twelfth ribs were all dry roasted at 325 Farenheit. Boned and unboned roasts (sixth to eighth ribs) were cooked by conventional and electronic methods. Only significant results are reported herein.

Objective tests using the Warner-Bratzler shear indicated roasts of Shorthorn animals to be the most tender of the four breeds.

Effects Of Gamma Radiation In Concurrence With Certain Environmental Conditions On Lethal And Physio-Chemical Responses Of Penicillium Expansum L., Tsong-Wen Chou

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In vitro investigations were conducted to study the lethal effect of gamma radiation on the fruit spoilage fungus Penicillium expansum under certain environmental conditions, and to study some physio-chemical changes in the fungus induced by the radiation which may be related to the death of the fungus or its ability to invade fruits.

The radiation sensitivity of P. expansum conidia was influenced by such factors as nutritional condition of the post-irradiation media, age of the spores, delayed plating, heat treatment, and chemical sensitizers. Higher survival was obtained when irradiated conidia were plated on Czapek solution agar (sugar-salts medium) than on …

Activation Of Prorennin, Nazar A. Shukri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Purified prorennin appeared to be homogeneous when subjected to chromatography on a Diethylaminoethyl-cellulose and to electrophoreses in starch-urea-gel. Crystalline rennin was heterogeneous, and was resolved into six components when analyzed electrophoretically. When crystalline rennin was chromatographed on a column of Diethylaminoethyl-cellulose two distinguishable peaks were observed which corresponded to B- and C-rennin. Unlike crystalline rennin, rennin freshly activated at pH 2.0 or 5.0 was essentially homogeneous.

Rennin resulting from activation at pH 2.0 and 5.0 appeared to be different. Rennin activated at pH 5.0 was eluted faster from Diethylaminoethyl-cellulose column, and moved slightly faster in starch-urea-gel electrophoresis, than rennin activated …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Each of thirteen lots of Cheddar cheese was made from 430 lb. of milk, and the protein recovered in the cheese and whey was compared with that in the original milk. Protein determinations on the milk, cheese and whey were made by an acid orange 12 dye binding test, and by Kjeldahl analysis. Similarly fat recovery was determined by using the Babcock fat test on milk, the modified Babcock test on cheese, and the Mojonnier test on whey. The total weight recovered as cheese and whey was 99 ± .6% by Kjeldahl analysis and 97.7 ± .6% by the dye …

The Contribution Of Summer Tourism To The Utah Economy, William D. Brakel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The increase in household income attributed to expenditures by Utah motor vehicle tourists from June 15 to September 5, 1969, was estimated using income multipliers from input-output analysis. Tourist expenditures were gathered through the distribution of postage-paid diaries to non-residents entering Utah. Expenditures were also segregated for Cache County, Utah. The income multipliers from state and county input-output models were used to estimate the impact of applying the state model to county data.

Approximately 927,250 tourist parties to Utah spent an estimated $37,842,816, increasing household income $65,018,557. Likewise, approximately 67,709 tourist parties spent an estimated $798,966 in Cache County. The …

The Hyrum And Beirdneau Formations Of North-Central Utah And Southeastern Idaho, James F. Eliason

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Hyrum and Beirdneau Formations of North-central Utah and Southeastern Idaho represent rocks of late Middle Devonian (Givetian) to upper Upper Devonian (Famennian) age. They are disconformably underlain by the Early Devonian Water Canyon Formation in most cases and disconformably overlain by the Devonian-Mississippian Leatham Formation or the Mississippian Lodgepole Formation.

The Hyrum Formation is divided into five members based on lithology and color changes. The five members are: (1) Samaria, (2) Lower Dolomite, (3) Lower Carbonate-detritus, (4) Upper Dolomite, and (5) Upper Carbonate-detritus Members. The Samaria Member is the only fossiliferous unit within the Hyrum Formation.

Survival And Distribution Of Rennin During Cheddar Cheese Manufacture, John Ta-Chuang Wang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Residual rennin in cheese whey and curd was measured by using a special sensitive substrate. 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 …

Adaptation To Dietary Protein Of Nitrogenous Components In Blood And Urine, Whang Hea Kim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study was made of the adaptation to dietary protein of nitrogenous components in blood and urine of rats and humans. Forty-four mature male rats were adapted to a low protein diet (10 per cent casein diet) for three weeks before they were divided into two groups. Four rats were then killed for a control, and twenty of the remaining rats were switched to a high protein diet (40 per cent casein diet) and the other twenty continued to be fed the low protein diet. Four rats fed each level of protein were killed 2, 4, 6, 8, and 10 …

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 …

Microenvironmental Effects Of Erosion Control Treatments On Seedling Survival In A Southeastern Utah Salt Desert Area, Ross W. Wein

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of the microclimate of erosion control treatments was carried out in two habitat types in a semiarid southeastern Utah, salt desert shrub area. The soils are highly eroded Mancos shale and support a low density of salt desert shrub species which offers little protection against high intensity summer convectional rainstorms.

Gully plugs and contour furrows had been installed by the Bureaus of Reclamation and Land Management to prevent runoff of soil laden water which results from these summer rainfalls. Formerly this sediment was carried to the Colorado River and deposited in Lake Powell.

The purpose to t he …

The Influence Of Teaching Experience Upon School Counselors, John Whorton Allen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The increased demand for more school counselors since World War II raised many questions concerning their preparation and training. One of the most controversial topics has been that of requiring teaching experience as a prerequisite for counselor certification. We find ourselves in a milieu of controversy in which some advocates are proposing that teaching experience can handicap the counselor in his effectiveness while others are saying that teaching experience is a vital prerequisite for counselor effectiveness.

Catalytic Effect Of Soil Components On The Nitrite Transformation In Buffer Acid Solutions, Laxman G. Kuratti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrite decomposition in buffer solutions of pH 3, 4, and 5 was observed to be a first order reaction with rate constants (k) 6.39 x 10^-3, 1.15 x 10^-3, and 0.17 x 10^-3, respectively. When 10 grams of two different soils were introduced, the reaction was catalyzed in all three pH conditions studied. This effect, however, was more pronounced in pH 5.

When 10 grams of soil were introduced, all the added nitrite was not recovered. The deficit ranged from 17 to 30 parts per million when 150 parts per million nitrite nitrogen was …

The History Of Raymond, Alberta, Canada, Holger B.C. Tychsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The intent of this study was to preserve the historical heritage of a small Canadian community. The thought that in the strength of a community lies the strength of a nation.

The following things were taken into consideration in giving a complete picture of Raymond: (l) The early history which entailed the parts that the Indians, the whoop-up saga, the trader, the trapper, and the Northwest Mounted Police played in the development of Western Canada and Alberta. (2) The desire of the Government to open the western prairies for settlement which brought the Mormon people who were seeking new homes …

Effect Of Foliar Application Of Urea And Ammonium Nitrate On The Dry Weight And Protein Content Of Maize Plants, Alvaro Fiallos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Urea and ammonium nitrate were applied to leaves of maize plants growing in growth chambers on nutrient solutions containing three different concentrations of ammonium nitrate. Dry weights, and the soluble protein contents of leaves, sterns and roots we remeasured.

Both urea and ammonium nitrate did increase the dry weights of leaves and stems when ammonium nitrate was used in the nutrient solutions (0.5 and 2.5 mM/ liter). When nitrogen was not used in the nutrient solutions, no increments of dry weight occurred. The protein contents of leaves were increased for plants in the same nutrient solutions that produced increases in …

Cpi Achievement Motivation Scales In Differential Prediction Of Academic Achievement, Dwight J. Petersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The grade-point average (GPA) of 4 groups of college sophomores, representing high and low scores on the CPI Ac and Ai scales, was analyzed to test the hypothesis that conforming and independent achievement motivation (as measured by the CPI) is related to scholastic achievement reflective of conforming or independent behavior. Specific hypotheses regarding differential achievement as a function of Ac and Ai scores were tested and, in general, supported. From this study, it was found that the CPI Ac and Ai scales do provide a basis for differentially predicting the scholastic achievement of students in settings rewarding dependent and/or independent …

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 …

A Formula To Express Evapotranspiration As A Function Of Soil Moisture And Evaporative Demands Of The Atmosphere, Aldo L. Norero

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A mathematical expression was developed and tested which describes the relation between evapotranspiration and soil moisture. A general premise of this mathematical model is that the evapotranspiration-soil moisture relationship is determined by interaction of climatic, soil and plant factors. The basic model is

dETa/dYs = -ke[1-(ET_a/ET_mx)]

in which ET_a is the actual evapotranspiration, Ψ_s is the total soil water potential, k is a proportionality coefficient, ∈ is the soil moisture extraction capacity of the atmosphere , and ET_mx is the evapotranspiration that would occur from a particular crop-soil unit when soil moisture was …
