Adaptive Changes Of Some Enzyme Activities In Rats And Humans To Dietary Protein, Jung Ja Kim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of the adaptive changes of some enzyme activities to the dietary protein intake was made in the liver, kidney, and pancreas of rats and serum of humans.

The rats fed the 40 per cent casein diet had a higher rate of weight gain and the weights of the liver and kidney were higher than in the rats fed the 10 per cent casein diet.

Three enzymes involved in the elimination of excess nitrogen from the body were found to show a similar response to increased dietary protein intake. These enzymes were: D-amino acid oxidase in the kidneys, arginase …

Extraction Of Rennet From Fresh Frozen Vells, Neil Harvey Clarke

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A method was developed for the extraction of rennet from fresh frozen vells. Frozen vells were partially thawed and minced in a Hobart "Wonder worker." The tissue was treated with 2.0 per cent potassium alum and allowed to stand for 20 hours before sufficient 0.45 M disodium phosphate was added to bring the pH of the mixture to 5.7. Dry sodium chloride was added until the salt concentration in the moisture of the mixture was 10 per cent. The tissue was then mixed with 3/4-inch pumice gravel in a volume ratio of 1 to 2 and packed into extractor columns. …

The Effect Of Oven Temperature, Cooking Method, And Breed On The Tenderness, Juiciness, And Flavor Of Beef, Carma B. Stembridge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of oven temperature, dry-roasting, and breed on the eating quality of beef was determined by sensory and objective methods. Two adjacent standing rib and two adjacent chuck roasts of prime, choice, and good grades from animals of Hereford, Shorthorn, and Charolais breeding were dry-roasted. Control roasts (9-12th ribs) were cooked at 325 F. Experimental roasts (6-8th rib and two chucks) were assigned an oven temperature of 325 or 250 F at random. All roasts were allowed to reach ah internal temperature of 155 F as recorded on a potentiometer.

The Secondary Benefits Of Irrigation Water: An Economic Appraisal, Erik Bruce Godfrey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The secondary or external benefits of increasing the availability of water for irrigation and changing the allocation of an existing water supply was analyzed from a theoretical point of view.

"Input-output" models for Cache County, Utah, and for the state of Utah were used to indicate the intersectoral relationship of water used by agriculture and other sectors in each economy.

The indirect value of water used by agriculture in Cache County was estimated. A method that extended the procedure used in this thesis was proposed that could be used to estimate the value of water in ether sectors. A "water …

Comparisons Of Phytoseiid Predator Populations In Sprayed And Unsprayed Apple Orchards In Cache Valley, Utah, Yeboa A. Dodoo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparative study of phytoseiid populations was made of two well-cultivated and regularly sprayed apple orchards with two unsprayed orchards in Cache Valley, northern Utah.

Two phytoseiid species, Typhlodromus mcgregori Chant and T. occidentalis Nesbitt were observed on the apple leaves, under the bark, and occasionally in the litter and soil. Amblyseius cucumeris (Oudemans) occurred in the soil and litter and occasionally under bark. T. mcgregori was dominant in the unsprayed orchards, and T. occidentalis in the sprayed.

Of the phytophagous mites, which served as food for the phytoseiids, the two-spotted mite, Tetranychus urticae Koch was dominant. Other phytophagous mites …

Effects Of Range Plant Foliage Removal On Soil Moisture Regime At Two Elevations In Central Utah, John C. Buckhouse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During 1966 and 1967, a range plant clipping study was conducted at two locations in central Utah's Ephraim Canyon. It was found that extreme clipping treatment resulted in a significant increase in soil moisture due to a presumed decrease in transpiration during 1967. At the lower location, 7,100 feet elevation, a difference of 5.4 inches over a 5 foot soil profile was noted between the extreme and control clipping treatments in 1967. At the upper location, 10,000 feet in elevation, a savings of 3.6 inches soil moisture was observed over the 5 foot soil profile in 1967. Other clipping intensities …

A Study Of The Amount And Quality Of Poetry Read On The Primary Grade Level In Selected Utah School Districts, Betty Farnsworth Spencer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary grade teachers of the Cache, Logan, and Box Elder School Districts were used in this study. A questionnaire was developed that would be an effective measurement of the information needed to evaluate or substantiate the hypothesis which was: It is believed that less than 50 percent of the primary grade children have poetry read to them daily as part of the curriculum. Furthermore, it is believed that much of the poetry read does not meet the standards of "good poetry for children" as measured by experts in this field of learning.

The study revealed that only 11 percent …

A Description Of The Planarian Phagocata Crenophila, New Species, From Utah, Jerry H. Carpenter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A new species of planaria in the genus Phagocata was found in several springs and spring-fed streams in Logan Canyon, Cache County, Utah. This species was named Phagocata crenophila because it greatly prefers to live in springs and it seems to be adapted behaviorally to this type of habitat. Serial sections and whole mounts were made by standard methods in order to study the anatomical features which are necessary for identification of planarians. The distinguishing features of this species are the following: testes ventral and extending from near the brain to near the posterior end, ejaculatory duct opening ventrally from …

The Value Of A Trout Stream Fishery, Archie Allen Dyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The data analysis indicated that travel distance, user age, and user income level are important determinants of use of trout streams.

These variables were incorporated into regression analysis to develop a use-prediction model.

This use-prediction model was used to determine predicted use levels of sample streams. The predicted use levels combined with travel costs and expenditures on new fishing equipment were used to derive a statistical estimate of the demand schedules for the sample streams.

These statistical demand curves were subjected to consumer surplus procedures to determine the values of the sample streams.

A Planning Analysis Of Utah Lake To Determine Its Recreational Potential, Robert D. Talbert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah Lake, located near Provo, Utah, is a lake of relatively low recreational development. There are certain inherent conditions that contribute to this situation. Four of them are, water level fluctuation, pollution, turbidity and the close proximity of other recreation sites of possible high desirability. This thesis explores these four problems and offers solutions and recommendations to solve or otherwise control their effect on recreation at Utah Lake.

The water level fluctuation will be under greater control after the Central Utah Project completes certain alterations in the lake and its watershed. Some fluctuation will continue but by proper design of …

Distribution And Ecology Of The Desert Bighorn Sheep In Southeastern Utah, Lanny O. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In May 1965, the first investigation and research in the native desert bighorn sheep in Utah was undertaken. The study was centered in the White Canyon area, San Juan County, in southeastern Utah. Seven other areas along the Colorado River were found to have smaller reminant populations of desert bighorns.

The White Canyon population was determined to be between 124 and 144 desert bighorns (Ovis canadensis nelsoni), excluding lambs.

The desert bighorns in southeastern Utah return from surrounding range lands each year to the same areas, known as lambing grounds, to give birth to their lambs. Ewes under …

The Relationship Of The Wechsler Preschool And Primary Scale Of Intelligence (Wppsi) To The Stanford-Binet Intelligence Scale, Duane Reeder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Correlational comparisons were made between the Stanford-Binet, Form L-M, and the Wechsler Preschool and Primary Scale of Intelligence using children enrolled in a Head-Start program. The study was concerned with three hypotheses:

1.The correlations found between the I.Q. scores obtained on the WPPSI full scale, verbal, and performance scales and those obtained on the Stanford-Binet using Head-Start children as subjects would be significant at the .01 level.

2. The correlation between the WPPSI and the Stanford-Binet utilizing Head-Start children would not be significantly different from the correlation reported by Wechsler in the WPPSI manual.

3. Scores on the WPPSI verbal …

The Use Of Mental Imagery Among Young Children In The Acquisition Of Piaget's Principles Of Conservation, Richard C. Sweetland

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study attempted to discover some parameters in terms of mental age at which young children, ages five through eight, begin to utilize effectively their mental imagery in the learning process. Using Piaget's principles of conservation as a learning task, subjects were taught in one of two groups: Group one was instructed in conservation concepts by use of concrete example, in which case they were allowed to see, handle and manipulate materials as they underwent transformations. Group two received identical instruction but were called upon to use their mental imagery to visualize the materials undergoing transformations.

Based upon the administration …

Factors Associated With The Penetration And Colonization Of Tomatoes By Verticillium Dahliae, Terry Dee Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiments have demonstrated that Verticillium dahliae is capable of direct cortical penetration of roots and of subsequent distribution throughout plants of both resistant (Loran Blood) and susceptible (Meteor) varieties of tomato. Plants were inoculated by the root dip method and planted in sterile soil. After one week the fungus was isolated from the upper portions of both the susceptible and resistant varieties as indicated by growth petiole sections plated on PDA. The distribution of the fungus in the resistant plants was irregular, but in susceptible plants the fungus was isolated regularly from all petiole sections. In experiments using disposable growth …

A Biosystematic Study Of The Genus Aconitum (Ranunculaceae) In The Intermountain Region, Rex Cates

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study dealt with the Intermountain aconites of which the chromosome number of n = 8 was obtained.

The bumblebees, Bombus rufocinctus Cresson, B. appositus Cresson, and B. centralis Cresson, are the major pollinators of the allogamous and autogamous aconites.

Two-dimensional thin layer chromatography of cauline leaf extracts showed that the Intermountain aconites studied here consist of one chemical group.

The overall evidence indicates that the Intermountain aconites consist of one species, Aconitum columbianum Nutt., with two varieties, variety columbianum and variety ochroleucum A. Nels.

Biosynthesis Of Piperidine-2-Carboxylic Acid In Fluoride-Necrotic Glycine Max, Susan S. Martin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Synthesis of piperidine-2-carboxylic acid (pipecolic acid) in soybean was studied by infiltration of radioactive carbon labeled precursor and by experiments using enzyme extracts from control and fluoride-fumigated plants.

Pipecolic acid was synthesized from lysine in both control and treated plants. Normal plants, in which pipecolic acid had not been detected by conventional procedures, were capable of synthesizing pipecolic acid. Greater pipecolic acid synthesis was shown in treated plants than in controls, and was attributed to increased enzyme concentration induced by fluoride treatment.

Protein And The Pill- A Pivotal Partnership, B. Delworth Gardner

Faculty Honor Lectures

Two fearsome possibilities preoccupy thoughtful men everywhere in the world. These worries are unique to our own age and time. Lord Russell puts it succinctly, "The world is faced, at the present day, with two antithetical dangers: (a) the human race may put an end to itself by a too lavish use of H bombs; and (b) the human population of our planet may increase to the point where only a starved and miserable existence is possible, except for a minority of powedul people."

Each of these dangers has its own characteristics, its own special perils, and its own possibilities …

Bulletin No. 472 - Nutritive Value Of Seasonal Ranges, C. Wayne Cook, Lorin E. Harris

UAES Bulletins

Considerable information has been presented on the nutritive value of domestic crops but little is known about the nutritive content of range forage. Such information is fundamental to the management of ranges for effective livestock production.

The shortage of suitable spring range in the Intermountain region has caused increased interest in seeding depleted foothill areas to supply more spring forage. Many native foothill ranges with established stands of perennial grasses sufficient to show rapid response to conservative use may be more economically developed through better management practices. In any event, knowledge of forage production, palatability, and nutritive value of both …

Range Nutrition In An Arid Region, Lorin E. Harris

Faculty Honor Lectures

On the mountains, in the valleys, on the foothills and on the deserts of the Intermountain West grow millions of tons of vegetation. The chemical energy stored bv these plants is a potential source of useful energy for man. Some of the plant material has been used for fuel, other has been used as a source of lumber, chemicals, and paper, but the major part of this vast reservO'ir is useful to man because it is utilized by livestock. This native vegetation is grazed by livestock and they convert the plant energy to' high quality, desirable food energy for man.
