Effects Of Low-Level Chronic Radiation On Plant Nuclear Parameters As Related To Successional Patterns, Eric A. Rechel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A major issue facing nuclear power stations is how to effectively deal with radioactive waste. This waste, as it comes from a reactor, is emitting large quantities of ionizing radiation which is usually confined. Another form of radioactive wastes is the mill tailings from uranium processing plants. These tailings are sites characterized by low-level chronic radiation.

The mill tailings of the Vitro Chemical Plant, in Salt Lake City, Utah, have been a point of radionuclide concentration and environmental contamination for 20 years. These tailings may adversely affect both surrounding ecosystems and any biological systems seeking to become established on the …

Characteristics And Genesis Of The Payson And Trenton Soils, Hakeem T. Saif

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is necessary to study the genesis of the Payson and Trenton polypedons in northern Utah to understand why the Payson polypedon is an Alfisol, while the Trenton polypedon is a Mollisol. Even though the soil-forming factors appear similar, the soils differ at the order level. Two pedons, one belonging to the Payson polypedons and the other belonging to the Trenton polypedon, have been described and sampled by genetic horizons. Both pedons have essentially the same climate, slope, age, elevation, and are developed on the parent material of Lake Bonneville sediments.

Effect Of Drilling Fluid Components And Mixtures On Plants And Soils, Parvin Pesaran (Djavan)

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The concern about the environment has required that the effects of drilling fluids (muds) on surrounding areas be known. This study was initiated to investigate the effects of various muds on plant growth and on soils.

In preliminary studies in Phase I (31 individual mud components), it was concluded that the obvious dominant effects on plant growth of detrimental drilling fluid components included excess soluble salts, excess exchangeable sodium percentage, possibly a high pH in some mixtures, and undesirable physical conditions. The latter resulted from the sodium and/or starch, gums, and bentonite.

Phase II, the second year's study of the …

Income Distribution Effects Of Water Quality Controls: An Econometric Approach, Ming Chien Chen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The imposition of water quality controls may affect the economy chiefly by altering aggregate production and changing the factor payments, These two effects could not only reallocate resources among production possibilities, but also could change the distribution of benefits of production among members of the society.

This study attempted to provide a workable theory to establish an empirical test of the impacts of water quality controls on family income distribution. It consists of two separate areas: first, to analyze methodologies of measuring income distribution changes, and, second, to develop a theoretical model that is useful for empirical tests of the …

The Consequences Of Rapid Population Growth On Nigeria's Economic Development: A Simple Econometric Analysis, Richard A. Eniang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to examine the economic implications of a rapid population growth on Nigeria's economic development. It was particularly interesting to study the relationship, because at the present Nigeria is making some economic progress while undergoing a demographic transition. Apparently, despite the acceptable growth of the national income, the growth of the per capita output has not been encouraging. This output growth must have been hampered by the rather rapid population growth in Nigeria.

The neoclassical growth theory was basically employed to explain the growth of output in the economy in terms of both capital and …

Nitrogen Fixation, Ammonification, Denitrification In Great Basin Arid Soils, Brian Paul Klubek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The inputs and losses of nitrogen from Great Basin arid soils were studied using the acetylene reduction and 15_N techniques. Filamentous blue-green algae were observed to be the predominant algal group in the soil crusts. The bacterial association with this group of algae suggest a phycosphere-like effect, thus allowing heterotrophic nitrogen fixation and denitrification to occur. Up to 17.5 mg N/100 g soil was found to have been fixed in surface soils (0 to 3 cm) during a three week incubation period, while 45.9 mg N/100 g soil was fixed in a five-week incubation period. Ammonium sulfate and ammonium …

Increased Calf Production And Returns From Improved Range And Livestock Management On A Northern Utah Ranch, Michael H. Ralphs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The operating costs for farms and ranches in the United States have increased 81 percent between 1970 and 1976. Calf prices over this same period have fluctuated dramatically and have fallen from a high of $58/cwt in 1973 to a low of $26/cwt in 1975. Since 1973, the increasing operating costs have exceeded the returns gene rated by the low calf prices and have left operators in a negative financial position. This case study has shown that the operator has increased both the scale and efficiency of his operation through improved lives tock husbandry and range improvements, yet has been …

A Study Of Rest Period, Hardiness, And Bud Development Of The 'Concord' Grape, Mervin Gayle Weeks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The length of the 'Concord' grape rest period was evaluated during 1974-75 and 1975-76. Cuttings were placed in a 25 C growth chamber every two weeks from October through April. Number of days to reach 50 percent full bud swell was plotted to determine rest completion. Seven years of weather data and full bloom dates of 'Concord' grapes from Prosser, Washington were statistically analyzed to give another estimate of rest completion. Rest was terminated after about 830 chill units.
