The Impact Of European Economic Integration On Israel's Export Of Oranges In 1970, Moshe Gottlieb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is an attempt to evaluate quantitatively as well as qualitatively possible future developments in international trade of oranges and tangerines, and the possible impact of these developments on the export of oranges and tangerines by Israel.

After World War II, international trade in oranges and tangerines increased rapidly, mostly as a result of the rapid rise in standards of living and the improvements in diet habits which took place in many countries at that time. These favorable marketing conditions encouraged the planting of new groves in the citrus growing areas of the world and particularly those of the …

An Evaluation Of Control On The Pocket Gopher, Thomomys Talpoides, On The Cache National Forest, Utah, Voit B. Richens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Monte Cristo area of the Cache National Forest has consistently supported a heavy pocket gopher infestation for many years. In 1957, and several succeeding years, infested range was treated with poisoned grain for pocket gopher control. Nearby range (also infested) was not treated. Thus, gopher-controlled range became available for comparative study, with periods of successive annual control of 1, 2, 3, 4, and 5 years. Within each of these areas (designated as treatments) were located two study sites in 1961 and three in 1962. Within each study site were three sample areas, and just outside each study site were …

The Free Sterol Content Of Selected Clones Of Alfalfa As Related To Seed Infestation By The Alfalfa Seed Chalcid, Rex Alton Richards

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The infestation of twelve selected clones of alfalfa by the alfalfa seed chalcid was measured. The free sterol content of the stems, leaves, flowers and pods of these clones was determined. A check was made to see if there was a correlation between the sterol content and the chalcid infestation.

Differences were found among the clones in the sterol content for each plant part. There were also significant differences in percent chalcid infestation in the 12 clones. Duncan's New Multiple Range Test pointed out which clones differed Significantly from the others.

Using linear regression analysis, the correlation coefficient of the …

The Influence Of Supplemental Irrigation And Environmental Factors On The Yield And Nutrient Composition Of Napiergrass, Modesto Capiel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adoption of supplemental irrigation as a practice in Puerto Rico will be slow. Because irrigation is thought to be needed only occasionally, farmers look at it as an uneconomical operation. Even in the agricultural policy, supplemental irrigation is treated lightly, with limited funds allocated for research in this area.

A Comparison Of Two Non-Verbal Intelligence Tests As Predictors Of Academic Success Of Navajo Students, Stanford S. Larson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was a search for a valid and reliable tool for the measurement and appraisal of the Navajo student at Intermountain School whose cultural and bilingual background make many highly verbal tests untrustworthy. The two tests chosen for the study were the Chicago Non-verbal Examination and the Cattell Institute for Personality and Ability Testing Culture Free Test. It was assumed that these tests would call attention to students who had good intellectual ability but were below standard in reading and verbal development and had been overlooked because of their lack of verbal fluency.

The two tests were administered to …

Forage Yield And Chemical Composition Of An Orchardgrass-Bromegrass Pasture Mixture As Influenced By Clipping Frequency, Nitrogen Fertilization And Irrigation Regime, Vinayak G. Gawai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The influence of agronomic practices on forage production and chemical composition of an orchardgrass-bromegrass pasture mixture was studied at the Greenville Farm, Logan, Utah, during 1960-1964. The soil is a well drained Millville Silt loam that has about a one percent slope and occurs on an alluvial fan. It is high in potash, phosphorus and calcium and is alkaline having a pH of 7.9 to 8.2.

Analysis of the clipping frequency showed that the yield of forage from four harvests was greater than from five harvests. This difference was greater on plots receiving high rates of nitrogen fertilization, and frequent …

Brisket Disease: Elemental And Oxalate Contents Of Cattle Forages On Two Utah Cattle Allotments, Raga Hafez I. Abaza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It was hypothesized that the hypocalcemia, hyperphosphoremia, hyperkalemia and the mild hypochromic microcytic anemia which existed in cattle afflicted with brisket disease could be due, at least in part, to nutritional disturbances. A chemical composition study was made of seven monocotyledonous plant species that comprise a major part of the diet and nine dicotyledonous plant species consumed by cattle and known or suspected of being poisonous. The plants analyzed were collected from two cattle grazing allotments, 7-mile and UM, in the Fishlake District, Fishlake National Forest, Utah, where brisket disease incidence is high. In each species the percentages on dry …

The "Starvation Effect" And Tryptophan Pyrrolase Activity In The Vermilion Mutant Of Drosophila, Ernest E. Shelton Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The enzyme tryptophan pyrrolase is controlled by the vermilion locus in Drosophila melanogaster and is normally lacking in the vermilion mutants. During this investigation it has been demonstrated that v¹;bw flies have tryptophan pyrrolase activity when grown under near starvation conditions.

During development of the fly there is a peak of enzyme activity in the early third instar soon after the transfer to starvation medium. A second peak of enzyme activity occurs during the pupal stage. The activity in v¹;bw pupae is about 15% of the activity found in cn bw adults.

In v …

Factors Influencing Population Growth Of Tribolium Brevicornis In The Laboratory, Amin Gulla

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To determine the effect of the factors of the environment (temperature, relative humidity, and food) on the population growth of Tribolium brevicornis, different levels of temperatures from 17.5°C - 37.5°C were used. Effect of these IeveIs of temperatures was tested upon both pre-embryonic and post-embryonic development. No hatching occurred at 17.5°C, but the threshold temperature (the minimum temperature for the development) was just before 17.5°C. The optimum temperature for the embryonic development was found to be between 32.5°C - 35°C.

With the use of the saturated salt solution according to Buxton (1931) and Buxton and Melanby (1934), certain humidity …

The Biosynthesis Of Aminolevulinic Acid In Relation To Iron And Enzyme, Daniel Ming-Yi Teng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The survey of plant species for aminolevalinic acid synthetase (ALAS) source was conducted. Under the conditions of this study, spinach leaves were found to be a good source of ALAS activity. The amount of amino levulinic acid (ALA) synthesized by the plant extracts was very small and was rapidly metabolized to porphyrins. ALA and porphyrin synthesis was found to be confined to the particulate fractions. Rupturing of the particles with ultrasonifier enhanced the penetration of succinyl-CoA and increased the activity. Direct study of the ALAS activity was enabled by the utilization of C¹⁴-compounds to the isolation by column …

Interaction Of Inorganic And Organic Fluoride Ions With Available Calcium On Root Growth In Triticum Vulgare, L., Subbanaidu Ramagopal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A method has been described to suspend seedling wheat roots in a saturated atmosphere. Wheat (Triticum vulgate, L.) seeds were germinated in aluminum trays and the seedlings transferred to seedling chambers. After a day's growth, the roots were treated with various concentrations of solutions containing CaSO₄, KCl, KF, NaCL, NaF, CH₃COONa, FCH₂COONa, K₂C₂O₄ and Na₂EDTA and observations were recorded 24 and 48 hours after treatment. The new root growth was described with respect to root hairs, root tissue collapse and root discoloration. Total length and …

Alkali Liberated Phenolic Acids From Alfalfa, Leslie Huey-Seng Huang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fourteen compounds were isolated from an alkaline hydrolyzed extract of alfalfa leaves by using cellulose thin layer plates. The R_f values, fluorescent characteristics, and color reactions were given for all the compounds isolated.

Eight of these were identified as trans-ferulic acid, trans-p-coumaric acid, trans-caffeic acid, o-coumaric acid, tricin, syringic acid, cis-ferulic acid and cis-p-coumaric acid. The identity of the compounds was confirmed by comparison of the R_f values on thin layer chromatograms, fluorescent characteristics under ultraviolet light, and color reactions of spray reagents with those of authentic samples. Three of …

Fluoroorganic Compounds In Relation To Hydrogen Fluoride Exposures In Leaves Of Glycine Max Merr., Julie Ye-O Cheng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soybean plants were fumigated in HF and the organic acid-fractions of the leaf extracts were compared to those of the leaf extracts from soybean plants grown in nutrient solution containing fluoroacetate. The extracts from both treatments contained fluoroorganic compounds that were chromatographically similar to fluoroacetate and fluorocitrate.

The fluorocitrate separated from HF fumigated leaves was found to inhibit aconitase prepared from pig-heart. This inhibition was similar to that caused by commercial fluorocitrate and the fluorocitrate synthesized using guinea-pig kidney. The aconitase from soybean leaves was found to be sensitive to fluorocitrate as the aconitase that isolated from pig-heart. Inorganic fluoride …

National Goals And Human Resources Development, Vernon L. Israelsen

Faculty Honor Lectures

During this year the United States will reach a population of 200 million persons. In materials things it is, by a wide margin, the richest nation on earth. With approximately 6 to 7 percent of the World's population it will produce at least one-third of the world's goods and services. Measured from almost any quantifiable category or criteria, it ranks first. In per capita income we are substantially above our nearest competitor. The gross national product in 1966 was $3770 per person. We could, on any afternoon, take the entire population for an automobile ride and have everyone sit in …

A Modern Philosopher's Stone, Grant Gill Smith

Faculty Honor Lectures

Alchemists, the forerunners of chemists, for more than a millennium sought the "Philosopher's Stone"-the transmuting agent that could change imperfect base metals such as lead and tin to the noble metals, gold and silver, and also serve as the Elixir of Life to heal the infirmities of man and prolong his existence on earth.

Where alchemy failed, chemistry, in little more than a century, has succeeded in finding the "Philosopher's Stone," for it is now not only possible to transmute one metal into another and heal many of man's infirmities, but scarcely a facet of man's life has not been …

Groundwater Development In Arid Basins, Dean F. Peterson Jr., Harold E. Thomas, J H. Feth, P. H. Mcgauhey, James H. Milligan, Wayne D. Criddle, Judge Lewis Jones, Dallin W. Jensen, Calvin G. Clyde, Bartell C. Jensen, C. E. Jacob, Jay R. Bingham, E. O. Larson

Reports

Summary: Groundwater development frequently provides a means whereby tremendous new economic opportunities are opened up. If supplies are overdrawn (mined) the ensuing regional economy may be able to affort replacements from more costly sources. In the United States the Salt River Valley of Arizona and the valleys of California provide examples. Two cases are treated in this paper, Israel and West Pakistan. In Israel, besides furnishing more than half of the basic source of water suppply, groundwater development provides opportunity for both quantity and quality management, which makes possible use of surface supplies and reclaimed sewage as firm rather than …

Use Of Uric Acid Analysis To Evaluate Chalcid Infestation In Alfalfa Seed, Gary M. Booth

Biology

The production of alfalfa seed is a major agricultural industry in various parts of the world, including the United States. One of the most serious pests of alfalfa seed is the alfalfa seed chalcid, Bruchophagus roddi Gussakovsii. The female chalcid destroys the seed by ovipositing in young alfalfa seed that is about nine days old. The egg hatches into a white larva in about four days. During the course of larval development, it devours virtually everything in the seed. When the chalcid completes its last or fourth larval instar, the insect may follow one of two alternatives of development: (1) …

Rearing Media For The Mountain Pine Beetle, Dendroctonus Ponderosae Hopkins (Coleoptera: Scolytidae), Robert G. Jones

Biology

Laboratory rearing of economically important insects such as the mountain pine beetle, Dendroctonus ponderosae Hopkins, is important. Both basic and applied laboratory research depend on a readily available source of insects. This need is most easily met by laboratory insect colonies which can be maintained and drawn upon for the entire year.

An Educational Study To Determine The Nutritional Value And Acceptability Of Dry Milk Among The Navajo, June C. Larson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

One day at the Intermountain Indian School, when a package of government surplus dry milk seemed to defy opening, a senior Navajo student offered her assistance anx easily opened the many boxes of milk. Upon inquiry, she said that she had opened many a box, especially in the springtime. She went on to say that most of their dry milk was used in the spring to feed baby lambs.

Later this same student told how her baby sister had died during the winter from something. The sister just seemed to get sick and then died. Could her death have been …

The Influence Of Clipping And Moisture Stress On Translocation In Crested Wheatgrass, James Miller Mayo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water movement in soils containing moisture below field capacity is extremely slow, thus requiring a continuous expansion of the plant root system to meet the transpiration demands placed on the plant (20, 21, 12, 19). It has been shown that internal moisture deficits result in reduced growth, and often death of the plant (22, 28, 25, 29, 34). Thus a healthy and continuously expanding root system may be necessary for good plant growth.

The Complex Formation Of Silver Ion With Ribonucleic Acid, Guanosine, Inosine And Related Compounds And Peroxidase-Like Activity Of A Haemundecapeptide Prepared From Horse Heart Cytochrome C, José Angel Reinosa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of nucleic acids in plant and animal cells as carriers of genetic information and as protein biosynthesis agents is well recognized. It is also known that nucleic acid is a component of all viruses.

Takahashi (45) and Fraenkel-Conrat (16) demonstrated that the protein component of tobacco mosaic virus is non-infectious to the host plant, although it is identical to the original virus morphologically. The virus ribonucleic acid (RNA) alone was infectious, however.

Deoxyribonucleic acid (DNA), which is present in chromosomes, displays a very specific function. The chromosome long has been accepted as the carrier of the hereditary unit, …

Preliminary Studies Of Germination Requirements Of Shadscale Atriplex Confertifolia Torr. And Ferm. Wats, Ijaz Hussain

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Shadscale (Atriplex confertilolia (Torr. and Frem.) Wats.) is an important component of the salt-desert-shrub vegetation type in the intermountain region. This species dominates a large portion of the 41 million acres occupied by this vegetation type. Shapscale reaches greatest importance at lower elevations of Utah and Nevada, where despite the low productivity due to its harsh habitat, this vigorous shrub furnishes considerable winter grazing for sheep and cattle. Gates et al. (1966) have observed that poor drainage conditions, coupled with low precipitation, results in the concentration of salts, a chief habitat factor determining the growth and distribution of this species. …

Immunity To Ostertagiasis In Calves, Leo F. Lejambre

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parasites are responsible for heavy economic loss to the livestock industry. The losses in cattle due to parasitism can only be roughly estimated, since many cattle do not die or become visibly sick. However, there are more subtle losses such as reduced growth rate, and decreased meat and milk production (Levine, 1961). In 1954 the U. S. Department of Agriculture published an estimate of the losses in agriculture over the 10 year period, 1942-1951. At that time, the best judgement of specialists in the Department of Agriculture placed the annual loss to parasitism in cattle at $19,026,000 of which $8,989,000 …
