Multivalue Methods, Clayton V. Henrie

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

Methods of solving ordinary differential equations with initial conditions are of a great importance to engineers and scientists. Many of these equations can be solved by well-known analytical techniques, but a greater number of physically significant differential equations cannot be so solved. Thus, the solutions of these equations must be approximated numerically. It is the purpose of this paper to investigate the techniques used in solving differential equations with initial conditions by "multivalue methods."

Multivariate Analysis Of Variance For Simple Designs, Yin-Yin Chen

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

The analysis of variance is a well known tool for testing how treatments change the average response of experimental units. The essence of the procedure is to compare the variation among means of groups of units subjected to the same treatment with the within treatment variation. If the variation among means is large with respect to the within group variation we are likely to conclude that the treatments caused the variation and hence we say the treatments cause some change in the group means.

The usual analysis of variance checks how far apart the group means are in a single …

An Evaluation Of Bartlett's Chi-Square Approximation For The Determinant Of A Matrix Of Sample Zero-Order Correlation Coefficients, Stephen M. Hattori

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

The single equation least-squares regression model has been extensively studied by economists and statisticians alike in order to determine the problems which arise when particular assumptions are violated. Much literature is available in terms of the properties and limitations of the model. However, on the multicollinearity problem, there has been little research, and consequently, limited literature is available when the problem is encountered. Farrar & Glauber (1967) present a collection of techniques to use in order to detect or diagnose the occurrence of multicollinearity within a regression analysis. They attempt to define multicollinearity in terms of departures from a hypothesized …

Food, Nutrition, And Health, Problems And Prospects, D. K. Salunkhe

Faculty Honor Lectures

Food, nutrition, and health - and their complex interrelationships - are necessities of life. Basically, nutrition depends on food; health depends on nutrition. Everyone needs to have enough good quality food to sustain himself. Satisfying that need on a world basis must be of concern to each of us.

Although accurate data are lacking, it is estimated that more than two-thirds of today's world population is afflicted by hunger and/ or malnutrition. Almost 300 million children are suffering physical and, probably, mental damage because of insufficient food. This evidence points to one of two conclusions: we have either too many …

Extractable-Emulsifying Capacity Of Hand And Mechanically Deboned Mutton And Organoleptic Acceptability Of Various Mutton Salami Formulations, Jack Robert Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt soluble extracts from mechanically deboned mutton were significantly higher (P < .01) in pH than the extracts from the hand boned mutton. An associated trend toward greater extractability, however, was not significant. Variation in emulsifying capacity between extracts from carcass parts were highly significant yet significant variation did not occur in the emulsifying capacity of hand versus mechanically deboned mutton. A new term, extractable- emulsifying capacity is presented which incorporates the extractability and emulsifying capacity of meat extracts into one value which should more accurately estimate the contribution of a meat ingredient in forming a stable sausage emulsion.

Salami, utilizing mutton, was formulated from experimental results which indicated that up to 10 percent mutton fat and 68 percent mutton lean was acceptable to panelists. Pork was preferred to beef for use in combination with mutton as determined by panel scores, however disagreement was noted between panelists. Panelists were unable to detect flavor, moisture or texture differences between the final mutton salami and a commercial beef and pork formulation. They did however prefer the appearance of the mutton salami (P < .05).

Effects Of X-Ray Induced Achlorhdria On The Utilization Of Dietary Calcium And Iron From Different Salts By Rats, Reid Scott Holbrook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dietary calcium has been classified as one of the minerals frequently limiting in the American diet (FAO, 1962) . Bone demineralization has been observed as a result of calcium deficient diets (Salomon et al., 1972), partial gastrectomies (Eddy, 1971) and inadequate hormonal balance (Albright et al., 1948). Although bone demineralization, or osteoporosis, has been attributed to many factors, the interrelationship of gastric acidity and the utilization of dietary calcium may be a key to the etiology of osteoporosis.

Formation And Anatomical Distribution Of Chlorophyll And Glycoalkaloids In Potato (Solanum Tuberosum L.) Tubers And Their Control By Physical And Chemical Treatments, Robert Bruce Jeppsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Applications of growth regulators and modifications of light exposures were investigated regarding their abilities to curtail the normal development of chlorophyll and glycoalkaloids in potato tubers responding to light. Four growth regulators were sprayed on the foliage of potato plants 14 days prior to harvest, of which two (Ethephon and N⁶-Benzyladenine [N6BA]) successfully retarded chlorophyll and glycoalkaloids in the harvested tubers. When tubers were dipped in N6BA, lower concentrations of the chemical promoted glycoalkaloid formation, while larger amounts were more inhibitory. When fluorescent lights were directed through colored cellophane filters, tubers receiving yellow and orange illuminations were inhibited …
