Geology Of The Upper Middle Creek Area Huerfano County, Colorado, J. H. Copeland

Open Access Master's Theses (through 2010)

The Sangre de Cristo Mountains of Colorado and New Mexico are, geologically speaking, relatively unknown. The equivocal nature of our knowledge of the range was a primary reason for studying a portion of it in some detail. Most of the previous studies have been concerned with the northern part of the range in Colorado, in the general area between Salida and La Veta Pass. This work has indicated that the complicated structure which characterizes the northern part of the range becomes simpler to the south. Therefore, a second objective of the current study has been to test this hypothesis. Thirdly, …

Development And Evaluation Of Laboratory Methods For Determining The Nitrogen Supplying Power Of The Irrigated Soils Of Northern Utah, Jerald Ross Wight

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen is the most widely needed and the most widely used of the fertilizer elements. Yet, in spite of the voluminous research work of evaluating the nitrogen status of soils, laboratory tests for the purpose of predicting need of nitrogen fertilizer are not very widely used. In general, laboratory tests for nitrogen supplying power have not given satisfactory results. Methods currently employed by a few laboratories can be classified either as biological or chemical. In the former method, the soil is incubated under optimum conditions and the amount of nitrate released over a given period of time is measured and …

The Influence Of Age On The Cation Exchange Capacity Of Plant Roots, Einard S. Haniuk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A yellowing which develops in some plants growing on naturally calcareous soils is called lime-induced chlorosis. The problem is complex, as indicated by Brown and Holmes (1956) and Porter and Thorne (1955). Species and varieties of plants differ in their iron requirements, susceptibility to lime- induced chlorosis, and inter acting soil f actors which affect iron supply (Thorne et al 1950). Chlorosis of plants does not appear, therefore, to stem from a common causative factor. At least a part of this difference has been found to be associated with the plant roots. Thus, through the use of resistant root stock …

The Effect Of Nutrient Levels In Nutrient Cultures On The Translocation Of Foliar Applied Nutrients, David D. Neher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since man first grew crops on calcareous soils he has probably been troubled with what we today call lime-induced chlorosis. This chlorosis has determined whether he grew certain desirable ornamentals or crops or whether he had to substitute others which were less desirable.

Lime-induced chlorosis is spread world wide. It has been reported in the vine and fruit growing regions of Europe, in the chernozem soils of Russia, and many other areas where the rainfall is relatively low and the soil is relatively high in calcium carbonate. In the United States it most frequently occurrs where the average annual rainfall …

Need was shown for safe working conditions and for personnel with attitudes of safety as well as skills and knowledge. Safety included freedom from mechanical, thermal, chemical, bacteriological, and psychological injury.

The descriptive method of research using the critical incident technique was …

A Comparison Of The Members Of A Children's Health Club With Non-Members By Use Of A Standardized Health Test And Behavior Inventory, Barbara Mcdonald

Loma Linda University Electronic Theses, Dissertations & Projects

Many methods of health education are being used today to help children and young people grow into healthy useful citizens. A health club is one such method which may be used to provide activities and health knowledge which may influence attitude and behavior.

The purpose of this study was to compare children who had been members of a health club with other children who were not members to see if there was any difference between the two groups in health knowledge, attitudes, and behavior as measured by a Health Achievement Test and a Health Behavior Inventory.

Twenty-two members of the …

A Comparative Study Of Graduates Of The Four And The Three Year Programs Of A Selected School Of Nursing, Valrie I. Rudge

Loma Linda University Electronic Theses, Dissertations & Projects

The purposes of this study were (1) to ascertain if the three year program in nursing at the Hinsdale Sanitarium and Hospital School of Nursing was preparing students for professional activities as well as did the four year program, and (2) to obtain information for use in curriculum planning.

A Comparison Of Internal Bicarbonate Of Some Chlorosis-Resistant And Chlorosis-Susceptible Plants, Ralph Barlow Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Iron chlorosis has been a srious problem for many years. This physiological disease has occurred so frequently on calcareous soils that it has been called lime-induced chlorosis by many of the workers. Because the western United States has so many soils of this type, the chlorosis problem has been of primary concern. Untold economic losses have been the result of this physiological disease.

Interveinal yellowing of the leaves along with loss of plant vigor and retarded growth characterize the disease. In severe cases die-back of the terminal growth and eventual death of the plant result. No single factor has been …

Studies On The Sampling Methodology Of Peas For Yield And Quality, Pratapsinha Chintamani Pendse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pea¹ growers have much at stake in getting high yields of peas of prime quality. The income accruing from a pea crop grown for processors is determined by the yield as well as quality. Therefore the farmers' efforts are directed toward growing such a crop.

Research workers are interested in knowing the yield of peas with known tenderometer values which will indicate the quality of peas. Present methods of field harvesting are costly and time consuming which tend to limit the number of varieties that can be satisfactorily evaluated for trial.

A comparison of sampling techniques with present harvesting …

Streamflow Forecasting For Blacksmith Fork River, Utah, Yu-Si Fok

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The method for streamflow forecasting by using Fourier Series and Multiple Regression as a mathematical model have been suggested and proved with high accuracy for the streamflow forecasting on Logan River, Utah by Professor Cleve H. Milligan and Dr. Rex L. Hurst. ^1/

In this thesis the method is extended to the forecasting for the Blacksmith Fork River, south of the Logan River.

Because the climatological data are not available in the Blacksmith Fork watershed, this thesis also provides a technique for using the available data from adjacent watersheds.

Lethal Concentrations And Detoxification Time Of Toxaphene For Goldfish, Gambusia And Rainbow Trout, Gar W. Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the past few years the Utah Fish and Game Department, as well as the fish and game departments of other states, has been spending fisheries money for fish eradication on both lakes and streams. The Utah Fish and Game Department recently suggested to the University that research be initiated on the subject of toxaphene as a fish poison. Consequently, a better insight into conditions that exist for a given water type could be developed.

A Manometric Method For The Determination Of Soil Carbonates In The Field, N. A. Polyzopoulos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In soil survey work the method now generally used to evaluate the carbonate content of the soil in the field is to observe the amount of effervescence that takes place when the soil reacts with dilute acid. The four degrees of effervescence usually recognized are designated by the symbols eo, e, es, ev and correspond roughly to a lime content of 0-0.5, 0.5-3, 3-15, and above 15 per cent, respectively. This, or course, is a very rough estimate and therefore a method is needed for the quantitative determination of carbonates in the field with a fair degree of accuracy. If …

An Investigation Of Complex Species In Silver Chloride Solutions I. Solubility Measurements ; Ii. Ion Exchange Methods, Harry G. Hecht

Theses and Dissertations

The complex species in silver chloride solutions have been investigated by solubility measurements and by ion exchange methods in this work. The solubility of silver chloride in solutions of varying chloride ion concentrations was determined by radioassay techniques. The method of least squares was used to evaluate the constants for the formation of the aqueous silver chloride and the dichloro-complex species; the values being 1.99 x 103 and 2.98 x 104, respectively, at 25.00°C. Aqueous solver chloride has been shown to be sorbed by Amberlite IR-120 from silver chloride solutions which have an ionic strength of 0.2. This sorption has …
