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 energy …

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 …

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

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

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 of glycogen …
