The Effects Of Radium On Certain Goldfish Blood Constituents And Organs, D. Wayne Linn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Background radioactivity from radium has long existed in ground and surface waters of the United States, but in the last 15 years radium has become a consequential unnatural contaminant of waters (Coulomb, 1955; Rone, 1952; Schlundt, 1910; Scott and Barker, 1956; Scott, 1961; and Tsivoglou et al., 1958). The onset of the atomic age initiated the increased processing of uranium ore for its uranium content. Radium is a daughter product and a by-product of uranium ore and its purification (Glasstone, 1958; and Tsivoglou et al., 1958). The uranium refinery wastes are released into streams in which all forms of aquatic …

Factors Affecting The Waterfowl Hunter Utilization And The Waterfowl Kill At The Bear River Migratory Bird Refuge, 1960-61, Stephen V. Goddard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1960 there were 1,955, 000 waterfowl hunters in the United States. These hunters spent $89,431, 000 (an average of $45.74 per individual) and 15,158, 000 hunter days in the field. The hunting population will increase 35 percent by 1975 (Anonymous, 1960).

The large increase in hunters will bring a proportional increase in the demand for places to hunt. Many states face the problem of providing enough public hunting for such an army of sportsmen. Studies by Kozlik (1958) in California, Gordinier (1957) and Friley (1959) in Michigan, and Bednarik (1957, 1961) in Ohio point out some of the problems …

Group Grain Feeding Versus Individual Grain Feeding Of Lactating Dairy Cows, Earl Max Sudweeks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Grain feeding is an important part of a dairy feeding program. Grain supplies energy in a concentrated form and when fed as a supplement to forage permits cows to maintain high levels of production. Also, if the forage is of low quality, additional protein and other nutrients can be supplied with the grain in a concentrate mix. By feeding a balanced concentrate mix, according to individual production, each cow receives the necessary nutrients for production. Dairy cows are usually fed grain individually.

Relations Between Transpiration, Leaf Temperatures, And Some Environmental Factors, Ronald Kay Tew

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Transpiration is the loss of water in vapor form from a plant. This is essentially the same process as evaporation except that it is modified by plant structure. Large quantities of water are removed from the soil, transferred through the conducting tissues of the plant, and dissipated into the air each day. As soon as the water is lost to the atmosphere, it becomes unavailable for human use.

The Effect Of Range Condition Upon The Production, Nutritive Intake And Digestibility Of Desert Range Forage In Southwestern Utah, J. Kent Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The 65 million acres of winter range in the Intermountain region furnish forage for about five million sheep and four million cattle each winter for approximately six months. These arid ranges are well suited for winter grazing, and are of paramount importance to the livestock industry. Many of these ranges were fully stocked by 1900 and as livestock continued to increase, many winter ranges were seriously over-grazed (Hutchings and Stewart, 1953). Today many of these ranges remain in a deteriorated condition. Forage production has decreased and desirable plants have been replaced by less desirable species.

Little is known about the …

Influence Of Age On Milk Production Of Holstein Cows In Utah, Marvin R. Green

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Production of dairy cows is influenced by many factors, among which are: genetics, nutrition, management, disease and age. Most of these factors can be modified to maintain a high level of production. Age, however, is beyond the influence of mankind; therefore, it is important to understand the effect of age on milk and butter-fat production.

An Economic Study Of Alternative Methods Of Obtaining Dairy Herd Replacements In Northern Utah, 1961, J'Wayne Mcarthur

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dairying ranked second in producing farm income in the state of Utah in 1929 (II). Twenty-two and two tenths percent of cash receipts from the sale of agricultural products came from dairying. Beef enterprises were the only larger source of farm income in the state, with 24.7 per cent of the total cash receipts. Because of the importance of dairying in the state, much work has been done to provide dairymen with information that will enable them to obtain a higher net return from dairying.

A Comparison Of Underachievers And Normal Achievers At The Upper-Elementary And Seventh-Grade Level, M. Nephi Manning

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

That each is born with differing capacities and potentials is self-evident. Both students and teachers should accept as their right and duty the task of bringing to full fruition these latent potentialities.

It is a cause of concern in the nation, among parents and teachers, and in later years among students themselves, that many of our youth fail to achieve that of which they are capable. This is a loss to society and a disappointment to the individual.

The purpose of this study is to add to the growing fund of knowledge concerning factors related to this important area of …

An Evaluation Of Antibiotics Upon Selected Dairy Organisms, Roy Brog

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was designed to answer a three-fold purpose. Primarily, it has endeavored to measure the inhibitory effect of three antibiotics (potassium pencillin, dihydrostreptomycin, and oxytetracycline) on lactic acid producing organisms. The lactic acid-producing organisms include Streptococcus lactis, Streptococcus thermophilis, and Lactobacillus bulgaricus.

The determination of an effective dose of a given antibiotic which will inhibit 50 percent of the lactic acid-producing organism (E.D.₅₀) will be established. A 50 percent cut in acid development will certainly lead to an inferior product.

The secondary purpose has related to the detection of inhibitory substances (antibiotics) in milk. What is …

A Study Of The Use Of The Hydrogen Peroxide-Catalase Treatment Of Milk In The Manufacture Of A Reduced Fat, Cheddar-Like Cheese, Lamar John Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nutritionists, the medical profession, and the public in general have become increasingly interested in low fat food products. Cheddar cheese, as it is now made, has a high caloric value and therefore may be discriminated against in some diets. The production of a reduced fat cheddar-like cheese would be of importance to the cheese industry by providing a reduced fat, high protein product.

The chemical nature of the casein furnishes the foundation for the body and texture in cheese. The body and texture of typical cheddar cheese is influenced principally by its fat and moisture content.

The use of hydrogen …

A Study Of The Effects Of Acidity On Shelf Life And Type Of Spoilage In Market Milk, Jagannath M. Kudale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The addition of the Streptococcus lactis culture in the pasteurized milk was studied, in an attempt to find the effects of the culture in prolonging shelf life of the milk. Various concentrations of the culture were tried to find the optimum concentration that would give favorable effect on keeping quality of the milk. It was found that the addition of Streptococcus lactis culture at the rate of 0.0001 percent has shown promising effects in prolonging shelf life of the milk at the storage temperature of 40 F.

In addition to the above study, effects of added acid in the pasteurized …

A Study Of A Bacterial Cause Of The Late Gas Defect In Cheddar Cheese, Rulon A. Chappell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

More of the manufacturing milk purchased from Utah's dairy farms is used for the production of cheese than for any other product. Approximately eleven and one-half million pounds of cheese were produced in Utah in 1959, of which more than half was cheddar. Many problems are encountered in the production of A-grade cheddar cheese. One of the most important causes of the reduction in grade is the late gas defect which accounts for about 50 percent of the cheese grading below A-grade. To increase the percentage of A-grade cheddar cheese in Utah, the late gas problem should be solved. The …

The Effect Of Feeding Fluoride On Some Enzymes Of Bovine Tissues, Prasertsri Sitachitt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluorides are usually found in nature as constituents of soils, water, and the tissues of animals. Fluorite or fluorspar (CaF₂), cryolite (Na₃AlF₆), apatite (3 Ca₃ (PO₄)₂ CaF₂) and sedimentary phosphate rocks are among the principle minerals containing fluorides found in nature. Traces of fluorides also occur in domestic water supplies in nature and also by induction in vegetation and animal feeds. From 0.5 ppm to 1.5 ppm of fluorides in drinking water is the range found to be beneficial in reducing the incidence of tooth decay in man. …

Biochemical Studies On The Effect Of Fluoride On Higher Plants, Shang-Fa Yang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluoride occurs naturally in plants, but its presence has attracted attention primarily in certain industrial areas where concentrations are elevated above normal by accumulation from the atmosphere. Certain plant species have been observed to be injured as a result of accumulation of excessive fluoride from the atmosphere. The general symptoms of fluoride injury are necrotic lesions and burning which appear first in the leaf tips and margins.

A Revisional Study Of The Bees Of The Genus Perdita F. Smith, With Special Reference To The Fauna Of The Pacific Coast (Hymenoptera, Apoidea) Part V, P. H. Timberlake

All PIRU Publications

In parts III and IV of this revision the species of the typical subgenus of Perdita belonging in the zonalis, halictoides, and octomaculata groups have been treated. This study is now extended to include the species belonging in that section of Perdita which may be called the ventralis group. In order to facilitate the study of these bees a key to the groups treated in Part III and subsequent parts is here offered. This key may afford some help in classifying the more typical members of the groups, but because of the multiplicity and extreme diversity of these …

Observations On The Behavior Of Bees In A Controlled-Environment Room, William P. Nye

All PIRU Publications

A detailed description is given of a controlled-environment flight room for the study of bee behaviour both in and outside the colony. Experiments demonstrated the ability of a colony to collect pollen, sugar syrup and water in the room, and to rear brood normally, increasing its strength throughout It months in spring. The behaviour of bees collecting powdered pollen from a tray 30 ft. [10 m.l from the hive was influenced by the amount and distribution of light in the room.

Alfalfa Seed Production Studies, M. W. Pedersen, William P. Nye

All PIRU Publications

From a practical standpoint, the culture to use is the one that gives the greatest net return. The study indicates that planting alfalfa for seed production in 24-inch rows at a rate of 1.5 pounds of seed per acre and thinning in the fall of the year after planting is best. For example, a field planted in the spring of 1963 should be thinned in the fall of 1964. Cutting out approximately every other foot within the row seems advisable. While there appears to be considerable latitude in the extent of thinning, weed problems are encountered if the stand is …
