Some Interrelationships Between Acetaminophen Detoxication And Dietary Sulfur Sources, Julie Catherine Hodges Dec 1981

Some Interrelationships Between Acetaminophen Detoxication And Dietary Sulfur Sources, Julie Catherine Hodges

Doctoral Dissertations

This investigation was conducted to study the effect of acetaminophen on sulfur constituents in livers of rats fed various diets differing in respect to inorganic sulfate and methionine. Sodium 35SO4 = was administered to label ester sulfates, 35S-cysteine to label ester sulfates and neutral sulfur compounds other than methionine and 35S-methionine to label ester sulfates and neutral sulfur and by a precursor relationship give an indication of the effect acetaminophen may have on the remethylation pathway. Time of isotope injections were varied so that immediate synthesis of sulfur compounds could be evaluated as well as the effect ...


Barriers To Implementation Of Energy Conservation Opportunities In Food Service Facilities, Dorothy Susan Mitchell Dec 1981

Barriers To Implementation Of Energy Conservation Opportunities In Food Service Facilities, Dorothy Susan Mitchell

Doctoral Dissertations

In 1978, expenditures for energy resources represented approximately 8% of the total operating budget in food service facilities (Barclay, 1979; Skaggs, 1980). Due to increasing energy costs, erratic availability of energy supply, environmental restrictions, federal and state regulations, energy management programs take on special significance. Energy management programs, which can include energy audits, frequently lead to a 10-30% reduction of energy consumption and subsequent cost reductions (Snyder and Symonds, 1977; Shirley and Turner, 1978). The audit permits an opportunity to determine potential energy conservation opportunities (ECO's). The purposes of this study were to determine the extent of exposure to ...


The Effect Of Protein And Caloric Restriction And Age On The Rate Of Liver Protein Synthesis Of Male Rats, Connie Watkins Bales Aug 1981

The Effect Of Protein And Caloric Restriction And Age On The Rate Of Liver Protein Synthesis Of Male Rats, Connie Watkins Bales

Doctoral Dissertations

The liver protein synthesis rate and protein content were studied in male Wistar rats fed low-, medium-, and high-protein diets at 2 calorie levels for 1 (12 animals per dietary group) or 2 (36 animals per dietary group) years. Ad libitum-fed (A) groups were offered semisynthetic diets containing 12, 20, or 28% casein. Restricted-fed (R) rats fed diets containing 18, 30, or 42% casein were provided two-thirds of the mean quantity of diet consumed by A groups and thus consumed the same amount of protein but one-third fewer calories than their ad libitum-fed controls. The fractional rate of liver protein ...


An Interdisciplinary Model For The Treatment Of Obesity In Young Girls, Annell St. Charles Mar 1981

An Interdisciplinary Model For The Treatment Of Obesity In Young Girls, Annell St. Charles

Doctoral Dissertations

The effectiveness of an interdisciplinary model in treating obesity in three young girls, ages 4 to 8, was studied over a 20-week period. Three subjects were selected from physician referrals and newspaper advertisement respondents. All of the subjects were clinically obese as indicated by weight and fatfold measures and had no apparent medical complications which would contraindicate treatment. Two of the subjects were white and one was of mixed racial background. One or both parents were obese in all subjects but none had obese siblings. The mother of each subject was the primary family member attending meetings.

Treatment effects were ...


An Effect Of Cyclotetraphosphate, Cyclotriphosphate And Hexametaphosphate On Glycogenesis In Rat Liver, Virginia Ann Laiming Mar 1981

An Effect Of Cyclotetraphosphate, Cyclotriphosphate And Hexametaphosphate On Glycogenesis In Rat Liver, Virginia Ann Laiming

Doctoral Dissertations

In order to investigate the effect of dietary phosphate additives on glycogenesis, rats were fed standard diets supplemented with cyclotetraphosphate, cyclotriphosphate or hexametaphosphate at a 0.1% level of phosphorus. A control group was fed orthophosphate at a similar level. After two weeks half of the animals received a test dose of 14C-glucose administered by stomach tube. After 2-1/2 hours their livers were removed to determine the incorporation of 14C-glucose into glycogen and total glycogen recovered. The remaining animals were sacrificed and their livers were removed to determine glycogen synthetase activity. Animals fed cyclotetraphosphate exhibited lower levels ...


Calibration Of Consumer And Homemaking Test Items Using The Rasch Procedure , Barbara Ann Woods Jan 1981

Calibration Of Consumer And Homemaking Test Items Using The Rasch Procedure , Barbara Ann Woods

Retrospective Theses and Dissertations

The purpose of the study was to use the Rasch procedure of item calibration to select test items in consumer and homemaking education, and to compile the items in a form usable by secondary teachers for assessing student achievement;From a pool of 230 items, five forms of a comprehensive achievement test were developed and administered to 1039 students who each responded to one form. There were 17 items deleted from the pool;The total t fit and the error impact were inspected to identify possible items for deletion. Items failing to meet the expectations of one or both criteria ...


Food Intake Assessment Of Elementary Children , Janis Bennington Van Buren Jan 1981

Food Intake Assessment Of Elementary Children , Janis Bennington Van Buren

Retrospective Theses and Dissertations

Purposes of this study were to describe the nutrient intake of upper elementary children by age and sex and to demonstrate criterion-related validity for the performance device, What I Usually Eat (National Dairy Council and Iowa State University, 1980). The device was designed to be used by teachers as an alternative method for estimating children's food intake;The parents of the 67 fourth and sixth graders who participated in the study kept detailed 7-day food records of their children's food intake. Female students comprised 55% of the sample. Average daily intakes of nutrients were calculated by age-sex groups ...

Quality Of Life And Propensity To Adjust: An Analysis Of Housing And Education , Salwa Ahmed Mohamed Said

Retrospective Theses and Dissertations

The overall objective of this dissertation is to advance the understanding of the factors that motivate housing and education adjustment. There are five specific objectives to investigate the relationship between housing and education applying to deficits, satisfaction, and propensity to adjust both domains. Another objective is to investigate the effect of housing and education satisfaction on the quality of life. The data are based on 485 completed personal interviews collected from urban and rural areas near the Iowa-Nebraska border;The model presented in this dissertation includes five levels of variables. These variables are analyzed in a parallel analysis representing the ...


Sexuality Attitudes Of Iowa Secondary Teachers , Jillian Rae Boyd Jan 1981

Sexuality Attitudes Of Iowa Secondary Teachers , Jillian Rae Boyd

Retrospective Theses and Dissertations

Two inventories to assess sexuality attitudes were developed. The first assessed attitudes toward teaching sexuality education; the second, attitudes toward sexuality. The inventories were used to determine sexuality attitudes of Iowa-high-school-home-economics teachers. Also examined were relationships among these attitudes, selected demographic variables, and the degree to which 25 sexuality topics were taught;A purposive sample of Iowa-vocational-high-school-home-economics teachers was used. The first inventory had 191 responses, and the second had 225. Most respondents (85%) completed both inventories;Analysis of data included: (1) factors extracted using the principal components method and rotated by the Varimax procedure, (2) factor reliability estimates using ...
