Dietary Supplementation Of Tarhana With Soya Bean Flour And Fish Protein Concentrate, Tahire O.K. Merdol

Masters Theses

Protein malnutrition is a problem in a major portion of the world where good quality protein sources are in short supply and expensive. Extensive studies have been carried out in order to improve the protein quality of certain existing foods which may be more abundant in a given community.

In this study the protein quality of a Turkish soup, tarhana, was determined by measuring its Net Protein Utilization (NPU), Diets containing tarhana were fed to rats at a level which gave 10 percent protein. The effect of supplementing tarhana with either soya bean flour or fish protein concentrate on the …

Effect Of Cis-Trans Isomers And Related Physical Properties Of Monounsaturated Lipids On Shortening Power, Aneta Joyce Ostrander

Doctoral Dissertations

The effect of cis-trans isomers on the shortening power of lipids was investigated. Lipid samples studied included: a commercial vegetable oil (control), oleic acid, elaidinized triolein, two samples in which elaidinized oleic acid was substituted at different levels for oleic acid, and two samples in which elaidinized triolein was substituted at different levels for triolein. Breaking strengths of plain pastry wafers were used for estimating the shortening power. Melting point, surface tension, interfacial tension and viscosity measurements were made on the lipid samples. Lipid composition analyses included gas-liquid and thin-layer chromatography.

Except at the 100 percent level of substitution, wafers …

Experimental Zoogeography Of Islands, Daniel Simberloff, Edward O. Wilson

Doctoral Dissertations

A technique for insular defaunation utilizing methyl bromide fumigation was evolved. Seven islands in Florida Bay, of varying distance and direction from potential zoogeographic source areas were censused exhaustively. The small size (45 ft. diameter) and ecological simplicity of these islands, which consist solely of red mangrove (Rhizophora mangle) trees with no supratidal ground, allowed the determination of all resident species. The completeness of the censuses was corroborated by chloropicrin fumigation. The breeding land fauna of these islands is composed almost exclusively of terrestrial arthropods, with 20-50 species usually present. Surveys of these taxa in the Florida Keys, with emphasis …

Response Of Small And Large Rib And Round Beef Roasts Of Two Degrees Of Finish To Two Rates Of Heat Application, Barbara Hammer Bayne

Masters Theses

Eighty roasts consisting of paired small and large, bone-in rib and boneless top-round cuts from five low-finish and five high-finish Hereford steers were studied. One cut from each pair was roasted at 200^oF and the other at 300^oF to end points of 152^o and 158^oF respectively, according to a balanced-lattice design. Tenderness, juiciness, and flavor were evaluated by a trained taste panel. An objective measurement of tenderness was obtained with the Warner-Bratzler Shear. Cooking loss and cooking time were determined also.

Cuts roasted at 200^oF had lower total cooking losses, longer …

Natural Variation In Abies Of The Southern Appalachians, John F. Robinson

Masters Theses

Determinations were made of several foliage, seed, and cone characteristics from material collected throughout the ranges of Abies fraseri in high elevations of Tennessee, North Carolina, and southern Virginia; Abies balsamea var phanerolepis in West Virginia and northern Virginia; and Abies balsamea from its southernmost distribution in Pennsylvania and southern New York.

Natural variation was investigated to determine relationships among these taxa, especially with reference to possible hybridity of A. balsamea var phanerolepis in West Virginia and northern Virginia. Much variation was found among species groups among stands within groups. Variation patterns suggested sampling from a north-south cline. Stand values …

The Effect Of Avitaminosis E On The Incorporation Of 35S-Sulfate By Rat Tissue Sulfolipids, Brenda Pearl Todd

Masters Theses

The relationship between the sulfation of brain and liver sulfolipids was investigated by comparing the fixation of a test dose of ³⁵S-sulfate by the sulfolipid fractions of brain and liver from rats fed vitamin E-deficient and -sufficient diets. Brain and liver tissue was divided into particulate and soluble fractions and the sulfolipid fraction extracted from each with chloroform-methanol. Following purification of the sulfolipid fractions by dialysis, the radioactivity in each fraction was determined by liquid scintillation.

The data obtained showed a statistically significant decrease in ³⁵S-sulfate uptake by the brain particulate sulfolipid in those animals fed a vitamin …

The Ecology Of Pieris Floribunda Benth. And Hook., An Ericad, In A Pine-Heath Community In The Great Smoky Mountains, Caroline Triplett Wingfield

Masters Theses

A member of the heath family, Ericaceae, Pieris floribunda Benth. and Hook. is endemic to the Southern Appalachian Mountains, its distribution being concentrated in the higher elevations of the Great Smoky Mountains National Park.

For many years these small shrubs have been noted growing beside the trails in the Park in some of the most xeric habitats, especially pine-heath communities, along with other ericaceous plants. By close examination of the climatology, soils and associated vegetation of these habitats, it was hoped that some clues might be found as to what factors allow P. floribunda to survive and reproduce in these …

The Effects Of End Point And Oven Temperatures On Histological Characteristics Of Beef Longissimus Dorsi, Mary Linda Bley

Masters Theses

(From the Summary): The effects of heating beef rib roasts to end points of 140, 158, and 170°F at 225 and 325°F on histological characteristics of longissimus dorsi were investigated.

Muscle fiber diameter was greater for raw than for cooked tissue. Generally, fiber diameter decreased at both oven temperatures as end points increased from 140 to 158°F. Raw and/or cooked samples contained straight, accordion pleated, and waved fibers. The predominance of straight fibers tended to decrease as wavy and accordion pleated fibers increased. End point and oven temperatures appeared to be unrelated to the occurrence of waves and/or …

Factors Involved In The Maintenance Of The Grassy Balds Of The Great Smoky Mountains National Park, Stephen Walker Radford

Masters Theses

The National Park Service, realizing that the montane treeless areas (grass balds) endemic to the Southern Appalachian Mountains were being rapidly overgrown by woody species where not grazed, burned, or managed, wanted to determine "if management of the balds is justifiable and if so what procedures would accomplish the aim without initiating a sequence of changes worse than those resulting from no management." (Park Service Contract)

Before a bald management program can be logically considered, factors involved in the natural maintenance must be determined. This particular study was conducted to examine possible factors. An intensive climatic documentation to two of …

Yield, Cost, And Acceptability Of Beef Sirloin Roasted By Forced Convection At Two Oven Temperatures, Marilyn Mccammon Davenport

Masters Theses

(From the Introduction)

The relationship of numerous factors to yield and palatability of meat has been under investigation for many years. Since meat is the most costly menu item for institutional food, establishments, factors which affect yield, cost, and palatability are of primary concern to food service managers.

With the development of forced convection ovens a relatively new approach to meat cookery was introduced to the food service industry. Borsenik and Newcomer (1959) pioneered in the development of forced convection cookery by installing a blower in a conventional oven. They found that cooking time was reduced and fuel …

A Census Of A Breeding Bird Population In A Virgin Spruce-Fir Forest On Mt. Guyot, Great Smoky Mountains National Park, Frederick Joseph Alsop

Masters Theses

Purpose of the study: The purpose of this study was to determine as accurately as possible the density of the bird populations in a virgin spruce-fir forest before changes in the forest resulting from aphid damage occurred. Accounts of the kinds of birds to be found in the spruce-fir biome are numerous. Some taken in the Southern Appalachians date almost one hundred years ago (Brewster, 1886). These reports give excellent records of the numbers of species to be found, but none give the numbers of individuals of each species, the density, to be expected for a given unit of measure …
