A Direct Measurement Of The Ratio Of The Reaction Cross Sections For Two-Photon And Three-Photon Positron Annihilation In Aluminum And Silver, Robert Maurice Heavenrich

Masters Theses

The probability of annihilation of a positron with its antiparticle, an electron, is spin dependent. Since both particles have spin component one -half, there are two possible relative orientations of their spins they can either be aligned (parallel) in the ³S, triplet, state with total spin component │S_z│= ½ n - ½ n = 1 n or they can be opposite (antiparallel) in the ¹S; singlet, state with│S_z│= ½ n - ½ n = 0. To conserve energy and angular momentum, annihilation from the triplet state must result in the creation of an odd …

Compensation For Reduced Stands In Burley Tobacco Experiments, Larry E. Archer

Masters Theses

Field experiments were conducted during 1968 and 1969 to study the effect of missing plants on the yield of hurley tobacco plots, to develop a procedure to adjust yield on the basis of stand, to test the procedure under actual field conditions, and to study the nature of yield compensa-tion by plants adjacent to missing plants. Burley 49 and MS Burley 37 x L8 cultivars were used with plants removed in five different patterns at four stages of growth. Both the patterns in which plants were missing and stages of plant removal had significant effects on plot yields. The estimated …

Some Behavioral And Demographic Characteristics Of A Bobwhite Quail (Colinus Virginianus) Population, Ronald Harry Saunders

Masters Theses

The study area was a 578-acre-tract within a quail management area on the Ames Plantation in West Tennessee. A total of 234 quail were trapped in 1971 and 410 quail were trapped in 1972. Seven quail (five unmated males and one mated pair) were radiotracked.

Quail were very sedentary during the breeding season (99 percent moved less than 1/2 mile). The average home range area of unmated males during the breeding season was 17.0 acres. Quail showed little inclination to switch areas used from season to season. Little change occurred in range used from spring to summer (98 percent moved …

Evaluations Of Systems For Growing And Finishing Steers On Pasture, Charles Milton Southall

Masters Theses

The purpose of this experiment was to evaluate systems of growing and finishing steers on pasture. The systems included a winter grazing phase, next a spring-summer grazing phase with supplemental feeding and finally a finishing phase.

During the winter, the steers grazed orchard grass or fescue pasture. As the pastures became short, a good quality mixed hay was Fed ad lib. The spring-summer grazing phase consisted of four treatments. Treatment number 1 was the control treatment and received no supplementation during the spring-summer grazing phase. Steers on treatment 2 were supplemented at the rate of 1.0 lb. of corn per …

The Cherry Plum Pigment As A Natural Red Food Colorant, Cathy Lou Hix Baker

Masters Theses

Objectives of this study were to evaluate the pigment in an extract from the leaves and peels of the cherry plum, Prunus cerasifera, as to method of extraction, purification, identification, mutagenicity, stability, and sensory threshold levels.

An extraction and concentration system using an ethanol-hydrochloric acid solvent and in vacuo evaporation, was developed to maximize pigment removal. Stability studies at low pH levels (<5) indicated a use for the extract in acid food systems, particularly beverages. Taste and odor threshold levels of the extracts in a citrus flavored liquid were above the depth of color needed in some of the red beverages marketed today. Further, no evidence that the extract was niutagenic was found in a single test utilizing four histidine operon mutant strains of Salmonella typhimurium.

Colorometric studies indicated the pigment from the cherry plum was a very close match both from visible color and light energy absorbed, to the partially banned FD&C Red No. 4.

The anthocyanin pigment present in both the …

Masters Theses

There are two major objectives in this study: (1) to compare a natural protein source, cottonseed meal, with urea, and (2) to determine the effect of adding limited quantities of hay to a high concentrate finishing ration. Both heifers and steers were used so a sex comparison was also made.

One hundred and seventy medium grade heifers were involved in a three-year study at the Greeneville Tobacco Experiment Station. The heifers were pregnancy checked, implanted with DBS, weighed, and alloted. There were two general phases of feeding each year. During the first phase, the heifers were given corn silage ad …

An Evaluation Of The Property Tax System Of Tennessee As Applied To Timberland--A Productivity Approach, Joseph Craig Allinder

Masters Theses

The enactment of the Property Assessment and Classification Act of 1973 created the need for a different method of assessing timberland. The Act exempted timber and provided for present-use assessments. The history and evolution of the ad valorem tax system in Tennessee were examined. Attention was given to the biases of the unmodified ad valorem tax as applied to timberland. The productivity concept was defined, and its variations were examined to determine which would be applicable for the assessment of timberland in Tennessee. Attention was given to the "bare-land", "modified", and "sustained yield" productivity approaches, and the market value adjustment …

Evaluation Of Site Quality Of An Upland Hardwood Forest At Scott County, Tennessee, Luis E. Rodriguez

Masters Theses

Management of upland hardwood forests involves many problems and is still at an early stage of development. A better understanding of the inherent complexity of these forests will be required before better schemes of forest management can be planned. Site evaluation is a management problem of high priority. Large numbers of species forming many-aged stands which are frequently abnormally stocked characterize upland hardwood forests. Under such conditions neither growth nor site index methodology can be directly applied to assess forest productivity.

This study was conducted to determine the feasibility of the site index methodology for evaluating site productivity of a …

An Evaluation Of Yellow-Poplar Samaras By Radiography, Russell Alfred Cox

Masters Theses

Control-pollinated samaras from 25 clones in a yellow-poplar breeding orchard at the University of Tennessee, Knoxville, were subjected to radiograph and germination analysis. A high correlation was found between filled samaras identified from radiographs and samaras that germinated. Significant differences were observed among clones used as females for percentage filled samaras; no such differences were present among pollen parents. Viability tended to be higher when clones were cross-pollinated than when the same clones were open-pollinated.

Analysis of 62 crosses and their reciprocals indicated significant difference between the two, thus, precluding a partial diallel analysis for viability and indicating a strong …

Seating Patterns In The College Classroom: The Relationship Between Spatial Location And Selected Role, Personality, And Status Variables, Dolores Burchell Jones

Masters Theses

Purpose and Theory

The Problem

Studies dealing with the use of space have been concerned primarily with territoriality, the way man perceives space through his senses, and with the manner by which culture affects the location of persons in space. This study, like others, falls under the rubric of spatial ecology in that it deals with the occupation of space. This study focuses on the college classroom in an attempt to determine if the occupation of space is systematically patterned, that is, whether particular areas of the classroom are occupied by students with specifiable characteristics. In this context, the particular …
