A Comparison Of Climatic Elements At Four Elevations In The Great Smoky Mountains National Park, Luther Allin Stephens Jr.

Masters Theses

Between January 1, 1947, and December 31, 1950, hourly temperature and relative humidity and daily precipitation and cloud cover data were collected at the 1,460 ft., 3,850 ft., 5,000 ft., and 6,300 ft. elevations in the Great Smoky Mountains National Park. These four years were part of a period of data collection extending from January, 1946, through March, 1951. These data were processed by a digital electronic computer, IBM 7040, under the control of data summary and potential evapotranspiration programs. Selected statistical tests were employed to compare the similarity of variation in some monthly mean values or to determine the …

Environmental Modification Of Bluegill (Lepomis Macrochirus Rafinesque) In Chilhowee, Loudon, And Norris Reservoirs, Tennessee, Edward Bartlett Smythe Ii

Masters Theses

This thesis reports the results of an investigation of environmental modifications of bluegill (Lepomis macrochirus Rafinesque) in Chilhowee, Loudon, and Norris Reservoirs. The three reservoirs are located in the Tennessee River drainage system.

The investigation was carried out between the spring of 1968 and the fall of 1969. Collecting was done by angling using both natural and artificial bait.

The evidence obtained by the investigation indicated significant differences occurred in the meristic and morphometric characters of the three bluegill populations when the data was tested statistically. It is concluded that the differences detected were probably due to environmental forces, …

Performance And Carcass Characteristics Of Feeder Heifer Calves Fed Different Amounts Of Concentrates With Urea-Limestone Treated Corn Silage, Gordon Bobby Idol

Masters Theses

Two feeding trials, one in 1967-68 and the other in 1968-69, were conducted at the University of Tennessee's Blount Farm to determine the effect of feeding different amounts of concentrates with urea-limestone treated corn silage on the performance and carcass characteristics of feeder heifer calves. A total of 288 animals were involved in the study. Treatments included delaying the feeding of a 6 lb. concentrate supplement for 0 (control), 56, 84, 112, 140 and 168 days during a period of high roughage feeding. Two other treatments involved the feeding of 2 or 4 lb. of concentrate during the entire roughage …

Patterns Of Species Segregation As Related To Topographic Form And Aspect, Homero Cabrera

Masters Theses

The purpose of this study is twofold. The first aim is to provide a quantitative description of the natural vegetation of a portion of Ash Log Mountain, Campbell County, Tennessee. The second aim is to test the hypothesis of homogenisty of the Mixed Mesophytic forest community, as proposed by Braun, with respect to minor topographic and aspectual variation of the landscape. The study area lies in Campbell County, Tennessee, in the Cumberland Mountains.

As a whole, the Southern Appalachian Region contains greater than twice the proportion of commercial forest lands than does the remainder of the nation. These forest lands …

Solubility Characteristics Of Residual Collagen As Related To Tenderness Of Beef Semimembranosus Roasted At 200O And At 300OF, Cheryl Ann Whetstone

Masters Theses

The effects of two heat treatments on cooking time, total cooking losses, energy consumption, meat tenderness, and collagen-solubility in 0.1 N NaOH and Ringer's solution were studied using five pairs of top round roasts obtained from three Hereford steers. One roast from each pair was cooked at 200⁰F and the other at 300⁰F to an end point of 158⁰F in the center of the semimembranosus muscle.

Semimembranosus muscles roasted at 200⁰F required longer cooking times per pound, had higher total cooking losses, consumed more energy, and were more tender than pair mates …

Shortening Power And Related Properties Of Lard As Affected By Substitution Of Elaidinized Lipid, Judith Ellen Klouda

Masters Theses

Shortening power and related properties of lard as affected by substitution of elaidinized lipid were investigated. Pastry wafers were prepared with shortenings of 0, 40, 60 and 80 percent levels of substitution of elaidinized lipid for lard. The shortenings were analyzed by gas-liquid and thin-layer chromatography. Penetrability of the worked fats and melting points were determined. Breaking strength of the wafers was measured on a Bailey Shortometer and indexes to flakiness and flavor. Extent of oxidation was estimated with a thiobarbituric acid (TBA) test.

The major component of the four shortenings was C18:1 fatty acid, ranging in concentration from 51.1 …

Effects Of Delayed Slaughter On The Quantitative And Qualitative Traits Of Pork Carcasses, Stanley G. Miller

Masters Theses

One hundred and twenty market hogs were used to study the effects of delayed slaughter and methods of decreasing liveweight shrinkage and deterioration of the quantitative and qualitative traits of pork carcasses. All hogs were secured from a commercial feedlot and slaughtered under commercial conditions.

Groups were held for 0, 24, 48, and 72 hours without feed. Two other groups were held for 72 hours with limited feeding to decrease liveweight shrinkage. Water was provided to all groups ad libitum.

Quantitative measurements and weights were taken to determine the effects of delayed slaughter on the important economic traits. Delayed slaughter …

The Utilization Of The Sulfur Of Sulfolipid By The Albino Rat, Susan Tredinnick Bowling

Masters Theses

³⁵S-sulfolipid was isolated from weanling rat brains and incorporated into a diet which was fed to rats for a period of nine days during which time urine and feces were collected daily in the initial study and continuously during the second phase of the study. The ³⁵S-sulfur from the sulfolipid was poorly absorbed, 20 percent of the ingested dose was excreted in the urine and 55 percent in the feces. The amount of radiation excreted in the urine plateaued after the third day with no significant difference occurring until the ninth day when there was a 96 percent …

An Effect Of Dietary Sulfate In Rats Fed Diets Low In Sulfur Containing Amino Acids, Helen T. Pfuderer

Masters Theses

Seven diets which were low in sulfur containing amino acids but with inorganic sulfate from 0.0002 percent to 3.130 percent in systematic increases were fed to rats. The sulfur as sulfate in freeze-dried and combusted lungs and livers of these rats was determined.

The data obtained showed a significant difference in both the amount of total sulfur in the lung as sulfate and the sulfur per mg. of dried lung. However, no significant difference was found in the total sulfur as sulfate in the liver or sulfur as sulfate per mg. of .dried liver. Since there is a high percentage …

A Study Of Population Density, Seasonal Movements And Weight Changes, And Winter Behavior Of The Eastern Box Turtle, Terrapene C. Carolina L., In Eastern Tennessee, Richard Albert Dolbeer

Masters Theses

During 1968, a quantitative and descriptive field study was made in a 23 acre woodland on a population of the eastern box turtle. The area was systematically searched and turtles were repeatedly collected, marked, weighed, and released. Trees were marked at 256 foot intervals so that the exact location of captured turtles could be recorded. A trailing device was used to study movements of some turtles.

Smaller turtles were found to be more active in the fall as 37.3 percent of the turtles captured during September and October weighed less than 300 grams as compared to 23.3 percent during July …
