Dietary Supplementation Of Tarhana With Soya Bean Flour And Fish Protein Concentrate, Tahire O.K. Merdol Dec 1968

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 …

Response Of Small And Large Rib And Round Beef Roasts Of Two Degrees Of Finish To Two Rates Of Heat Application, Barbara Hammer Bayne Aug 1968

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 200oF and the other at 300oF to end points of 152o and 158oF 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 200oF had lower total cooking losses, longer …


Natural Variation In Abies Of The Southern Appalachians, John F. Robinson Aug 1968

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 Aug 1968

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 Mar 1968

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

Introduction: 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 …


Factors Involved In The Maintenance Of The Grassy Balds Of The Great Smoky Mountains National Park, Stephen Walker Radford Mar 1968

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 …


The Effects Of End Point And Oven Temperatures On Histological Characteristics Of Beef Longissimus Dorsi, Mary Linda Bley Mar 1968

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 …

A Census Of A Breeding Bird Population In A Virgin Spruce-Fir Forest On Mt. Guyot, Great Smoky Mountains National Park, Frederick Joseph Alsop Mar 1968

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 …


Yield, Cost, And Acceptability Of Beef Sirloin Roasted By Forced Convection At Two Oven Temperatures, Marilyn Mccammon Davenport Mar 1968

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 …
