Nutritional Anemias In Selected Countries, Wun-Yuan Mei

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

Blood is a constantly changing, highly complex tissue which is concerned with the transport of cell nutrients, the elimination of wastes, and the maintenance of chemical equilibrium. The mature red blood cell takes about seven and half days to develop, then has a life cycle of 120 days. Many factors are involved in this complicated process. Many nutrients are required for the frame-work of the red blood cells and in the hemoglobin within these cells.

Anemia is a condition in which there is a reduction in the total circulating hemoglobin. Anemias may be described biochemically in terms of lowered hemoglobin …

Mesoscale Atmospheric Circulation And Diffusion Characteristics, Ronan I. Ellis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Constant volume superpressure pillow balloons were flown over a mountain valley downwind from a sharp ridge line. Balloon trajectories revealed and atmospheric soundings confirmed a persistent turbulently mixed adiabatic layer over the valley at approximately ridge top height except in the immediate lee of the ridge where strong vertical motions were observed. Temporary stationarity of the relative mesoscale turbulence was found to exist on a time scale exceeding 4 hours. Power spectrum analysis of component relative velocities showed greater variance in lower wave numbers and anisotropy in mesoscale turbulence. Eddy diffusivity coefficients for turbulence above the ridge height were K …

An Intensive Edaphological Characterization Of The Soils Of Malambito Experimental Station And Its Implications In Future Agricultural Research, William L. Rubink

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Malambito Experiment Station, in the Atlántico III project area, Department of Atlántico, Colombia, had almost no quantitative edaphological data on which to base agricultural research. Unexplainably low general yields as well as problem areas of deficient plant growth only confounded the results of field plot experiments. Intensive soil sampling and subsequent measurements of pH, EC_e of the saturation extract, and the four major cations disproved the previous suggestions that the crop growth problems were related to saline, sodic, or degraded soil conditions. The Ca/Mg+K+Na ratio, although significant when correlated with plant height, was sufficient explanation for only a small …

A Measure Of The Amount Of Phosphate Adsorption And The Rate Of Release Of Indigenous Phosphate From A Desert Soil, Robert Lindsey Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The capacity of a calcareous desert soil, Thiokol silt loam, to retain natural, as well as added, orthophosphate-P was measured by equilibrium adsorption employing a batch technique and evaluated using the two-slope Langmuir adsorption isotherm. From these data, corrected to account for indigenous soil P, a hypothesis was formulated as to the nature of retention of P by the soil, including the identification of two interfacial reactions involving P, and a value calculated for the adsorption maximum as defined by the Langmuir isotherm equation for P with soil at each of two soil depths and three constant temperatures within the …

Ice Nuclei Inventory: Wasatch Weather Modification Experimental Area, William F. Slusser

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several large sources of ice nuclei were identified for the Wasatch Weather Modification Experimental Area. When stable air masses remained over the area for several days, ice nuclei concentrations as large as 1750 per liter (measured at -20 C) were found at the surface. Concentrations as large as 6000 per liter were measured with an airborne ice nuclei counter over the smelter industry of the Salt Lake Valley. Ice nuclei concentrations during storm periods were usually less than 3 per liter, indicating an excellent potential for increasing precipitation amounts over the Wasatch Mountains through the release of artificial ice nuclei. …

Temperature Effect On Leaf Water Potential Measurements, Rex J. Prosser

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Silver foil psychrometers were used to monitor water potential in different portions of maize leaves which were subjected to temperature gradients. The psychrometers were preliminarily calibrated over standard NaCI solutions at temperatures ranging from 5°C to 45°C in an aluminum plate apparatus designed to provide uniform temperatures within each psychrometer even while overall temperature was changing. Based on the calibrations, empirical temperature correction equations were derived and used to correct psychrometer readings at different temperatures to equivalent values at 25°C. Temperatures on a single maize leaf were varied by placing the long leaf through an insulated box with several compartments …

Incorporation Of Protoporphyrin Ix Into Chlorophyll A And Purification And Properties Of (-) S-Adenosyl-L-Methionine-Magnesium Protoporphyrin Ix Methyltransferase, Jii Shieh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiments on the incorporation of ¹⁴C-protoporphyrin IX into chlorophyll indicate that ferrous iron may be involved in reactions between protoporphyrin IX and chlorophyll. Experiments using both health and chlorotic tobacco tissue for incorporation studies show that incorporation of protoporphyrin IX into chlorophyll was activated by Fe²⁺.

S-adenosylmethionine-magnesium protoporphyrin IX methyltransferase (E.C.2.1.1.11) which catalyzes the reaction between S-adenosylmethionine and Mg protoporphyrin IX to form S-adenosylhomocysteine and Mg protoporphyrin IX monomethyl ester was demonstrated in barley seedlings. Methyltransferase was found principally in whole chloroplasts and fractions containing mitochondria were disintegrated chloroplasts. Use of detergent Tween 80, precipitation with protamine …

Studies Of Porphyrin Biosynthesis In Higher Plants, Tsung-Chiang Chen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Uroporphyrinogen decarboxylase which catalyses the formation of coproporphyrinogen from uroporphyrinogen is located in the soluble fraction of tobacco leaves and was purified 72 fold through ammonium sulphate precipitation and calcium phosphate gel adsorption.

Kinetic studies indicated that the apparent Michaelis constant was 1 x 10^-6 for uroporphyrinogen III (pH 6.5; 37° C). Uroporphyrinogen III served as a much better substrate than uroporphyrinogen I under the standard conditions of this study.

Enzyme activity was inhibited by thiol reagents and heavy divalent cations.

Both chloride and fluoride salts inhibited the formation of coproporphyrinogen from uroporphyrinogen.

Enzyme activity was inhibited by several …

U.S.U And The New Toxicology, Joseph C. Street

Faculty Honor Lectures

Toxicology, a branch of science once concerned only with poisons for their medical effects and legal con sequences, has undergone in recent years a metamorphosis on a major scale. The general field of toxicology is defined as the qualitative and quantitative study of the injurious effects of chemical agents, as detected by alterations of structure and function in living systems (Murphy and Hayes, 1972). In common with most other disciplines it has benefited from a growing sophistication in research methods and has particularly flourished in the wake of major advances in physiology, biochemistry and the other basic sciences that serve …

Computer Programs Supporting The Teaching Of Statistics, Chien-Hwa Liu

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

During the past few years there has been an increasing interest in developing computer packages to enhance the teaching of elementary statistics. The conventional ways of teaching statistics have used such devices as desk calculators, tables of functions, short-cut calculating formulas and electronic calculators, etc. to manipulate the involved computations. Electronic computers, in the past decade, have been broadly used in universities and colleges in many ways. It is only natural to extend the use of computers to the teaching function. Remote terminals can now be installed in any classroom and bring the computer to the students.

Modification Of A Continuous Ice Crystal Replicator, Paul D. Thornley

Reports

A continuous ice-crystal replicator was modified by the addition of a gear drive to the cating wheel. This modification utilizes a positive drive force on the coating wheel rather than the friction force between the coating wheel and the film. The coating wheel operates successfully for at least 12 hours without slippage or damage to the film. Studies have uncovered several deficiencies in the replicator design which could be corrected. The correction of these deficiencies would lead to an improved quality of ice-crystal replicas. The need for continued studies in the fluid properties of Formvar solution is pointed out. Information …

Computer Simulation Of The Hydrologic And Salinity Flow Systems Within The Bear River Basin, Robert W. Hill, Eugene K. Israelsen, J. Paul Riley

Reports

Accompanying the increased use of water resources is an increases accumulation of chemical pollutants. Te prevent degradation of the water resources beyong useful limits, pollution inputs from additional uses must be quite accurately predicted prior to implementation of the new use. The model described in this report was formulated to provide the required predictive capability for the Bear River Basin. Modeling concepts of the hydrologic system are based upon the development of basin relationships describing the hydrologic processes which are linked together by the countinuity-of-mass principle. The salinity flow system is then linked to the hydrologic system based on the …

Sorption Kinetics Part Ii: Modeling Longitudinal Concentration Profiles In A Packed Bed Reactor, David W. Hendricks

Reports

A mass balance simulation model for sorption in a packed bed reactor was developed. All of the terms in the model, consisting of constants of the porous media, and functions, were evaluated by independent laboratory studies. The kinetic term was determined in Part I. Two numerical schemes (an explicit scheme and an implicit scheme respectively) with corresponding computer programs were developed and made operational. They were not tested against laboratory column results due to long times necessary on the computer and corresponding high costs. Laboratory testing consisted of measuring column profiles for six different packed columns at different flow rates …

Laboratory studies indicate dimethyl mercury may be a major product of microbial methylation of inorganic mercury. Although another methylation product, monomethyl mercury, has been extensively studied, the physical, chemical, and biologicl factors affecting the transport and food chain distribution of dimethyl mercury have remained unclear. This report presents results of laboratory studies of volatilization rates from water as a function of temperature and mixing conditions, uptake kinetics and equilibrium concentrations in algae,

Sorption Kinetics Part I: A Laboratory Investigation Of Six Proposed Rate Laws Using Batch Reactors, David W. Hendricks, Laxman G. Kuratti

Reports

Six proposed rate equations for sorption kinetics have been investigated by laboratory batch experiments involving some 270 individual “runs” to determine sorption uptake with time for varying conditions of initial sorbate concentration, temperature, and sorbent species. The sorbate selected was rhodamine-B dye, used because it will sorb readily and is easily measured. Two sorbents, Dowex 50 resin, and Filtrasorb 200 activated carbon were used. Temperature conditions were 10, 20, 30, and 40°C, and concentrations ranged from .0008 to 400 micrograms per ml, rhodamine-B. Analysis of data was computer automated, requiring as input only test conditions, instrument readings, dilutions, and corresponding …

Oxidation Of Thin Silver Films By Ozone And Atomic Oxygen, Lawrence R. Thorne

Undergraduate Honors Capstone Projects

Recently, thin silver film detectors have been used to determine atomic oxygen profiles in the 70-100 km region of the upper atmosphere. The detectors' sensitivity to atomic oxygen is the result of the formation of silver oxide(s) which cause their electrical resistance to increase. A common procedure to calibrate and to make these detectors more sensitive is to cycle them through a series of three or more oxidations and reductions. This paper indicates that this cycling makes silver films more sensitive to ozone, causing them to be usable only at heights greater than 38 km. Also reported herein are experimentally …

The French Influence On Eighteenth - Century English Literature, Linda Jane Grow

Undergraduate Honors Capstone Projects

The development of English literature in the eighteenth century was strongly influenced by France and French writers. Lately there has been an attempt to belittle the French influences. It is true that in the past the Gallic influence has been exaggerated, but it really cannot be overlooked.

Historically it is true to treat England and France as one country in respect to their literary activity between the middle of the seventeenth and eighteenth centuries. Roughly, there were about 100 years, between the execution of Charles I in 1649 and the execution of Louis XIV in 1793, during which there was …
