South Dakota Farm Boys Planning Farm And Nonfarm Occupations: A Comparative Analysis, Alan L. Loya Feb 1969

South Dakota Farm Boys Planning Farm And Nonfarm Occupations: A Comparative Analysis, Alan L. Loya

Electronic Theses and Dissertations

Farm youth are finding it increasingly difficult to enter farming as a life occupation, and are therefore faced with a difficult situation when it comes to choosing an occupation. The farm-reared boys must decide whether or not to continue the family tradition in farming, and if they decide not to follow this tradition, they must decide on a nonfarm occupation which they would like to enter. The future welfare of these farm youth is associated with the occupational choices they make at this time. Therefore, a comparison of the characteristics of farm boys who plan farm occupations with those who …

The Retention Of Fallout Particles On Roofs Having Different Slopes, Arden B. Sigl Feb 1969

The Retention Of Fallout Particles On Roofs Having Different Slopes, Arden B. Sigl

Electronic Theses and Dissertations

Since World War II the continual buildup and spread of nuclear arms has produced a pressure situation between nations. As more and more nations become nuclear powers and continue to expand their arsenals, the chance of a nuclear attack, either by accident or by specific intent, increases. If a full-scale nuclear attack should develop, the only chance of survival would rest -with a fully prepared population. Even with a fully prepared population many would not survive. The National Fallout Shelter Program is helpful in preventing casualties in the event of a nuclear attack. Studies show, however, that such casualties would …

Investigation Of The Dielectric Properties Of Grain At Microwave Frequencies, Arthur A. Kruse Jan 1969

Investigation Of The Dielectric Properties Of Grain At Microwave Frequencies, Arthur A. Kruse

Electronic Theses and Dissertations

The components of the complex dielectric constant of feed grains are obtained for the 8.5 to 12 gHz frequency range. The short-circuited wave guide method is employed to provide null-shift data for computer calculation of the first-order approximation of the real part of the complex dielectric constant under the simplifying assumption of negligible loss. Correction to this value is then made, where appreciable, by calculating the loss tangent from attenuation data independently obtained for the grains. The imaginary part of the complex dielectric constant then is obtained by multiplying the loss tangent by the real part. Curves of the real …

Isolation Of Keratinophilic Fungi From Soil And Wild Animals In South Dakota, William Urban Knudtson Jan 1969

Isolation Of Keratinophilic Fungi From Soil And Wild Animals In South Dakota, William Urban Knudtson

Electronic Theses and Dissertations

Very little is known of the ecology of keratinophilic fungi in animal populations and their habitats in South Dakota. Recent investigation of an outbreak of ringworm in blue foxes on a fur farm in South Dakota indicated that the source of infection may have been wild animals which had been captured and raised in the kennels previous to occupancy by the foxes. In recent years, a number of investigators have demonstrated that small and large mammals may carry keratinophilic fungi in their coats (13, 29-31, 52, 56-60, 63, 70, 77) and have postulated on the role of infected animals in …

Cell-Wall Analyses Of Diphtheroids Isolated From Cattle And Swine, Everett E. Scheetz Jan 1969

Cell-Wall Analyses Of Diphtheroids Isolated From Cattle And Swine, Everett E. Scheetz

Electronic Theses and Dissertations

Biever, working in this laboratory, isolated numerous diphtheroidal organisms from cattle and swine sources. These anaerobic diptheroids were morphologically similar to organisms in the genera Corynebacterium and Actinomyces. King and Meyer found that isolates of anaerobic diptheroids from human sources were more closely related to the Corynebacterium based upon metabolic and serologic differentiation. Their work consisted of separating A. bovis from several isolates of anaerobic diptheroids on the basis of the catalase test, litmus milk reactions, and the fermentation of xylose, salicin, and raffinose. However, Grasser reported that the fermentation reactions are variable and cannot be used as definite criteria …

Some Field And Laboratory Observations On Morchella, Reed Sanderson Jan 1969

Some Field And Laboratory Observations On Morchella, Reed Sanderson

Electronic Theses and Dissertations

The morel, Morchella, of which there are several species, abounds throughout the United States. Several common names have been applied to this organism depending upon the area. Names include sponge, sponge on a stalk, honeycomb (because of its appearance), common more, delicious morel, hickory chicken (it is found among hickory leaves), and mushroom (the most common name in South Dakota). Although this organism ranks near the top of any fungus collector's list as a food, little is actually known or at least recorded of the environment associated with its appearance. The purpose of this study was to gather as much …

Evaluation Of The Yield And Organoleptic Quality Of Split And Whole Country Style Cured Hams, Nickolas William Norder

Electronic Theses and Dissertations

Any evaluation of carcass or wholesale cut characteristics is generally based upon quality and quantity of lean meat. The quantity factor is of prime importance to the breeder, producer, processor and consumer. Extensive exploration of techniques to increase the relative yield of lean meat in the carcass has been conducted by animal breeders and livestock production personnel. Furthermore, studies concerned primarily with the development of processing methods which increase yield and final product net weight have been undertaken by the meat industry. Coupled with the quantity factor is the growing concern for product quality. A product with high consumer acceptability …

A Study Of The Relationship Between Ceratocystis Ulmi And Elm Callus In Vitro, Charles R. Mcmullen

Electronic Theses and Dissertations

In the course of studies dealing with the Dutch elm disease, it has become apparent that there.is a need for a rapid, efficient screening method for determining disease resistance. Tissue culture is a discipline that is now well accepted in the field of plant physiology, but is a rather new technique in the field of plant pathology. The investigations of diseased tissue, until recently, has been done with the intact plant. This study has investigated the possibility of studying the growth of the fungus on host tissue cultures as a screening technique.

The Production And Behavior Of Callus Tissue From Sorghum Vulgare, Vance J. Masteller Jan 1969

The Production And Behavior Of Callus Tissue From Sorghum Vulgare, Vance J. Masteller

Electronic Theses and Dissertations

The history of plant tissue culture dates back to the early 1900’s with the research of Gottleib Haberlandt in Germany. However, it was not until 1939 that any real success was achieved. Three independent scientists, Gautberet, Nobecourt, and White simultaneously through their work set the pace for plant tissue culture. Plant tissue culture is the isolation of cell or tissues from their association with other cells and tissues in the plant to one in which nutrients are supplied artificially and the cell or tissue acts as an individual. Once the plant cells or tissues have been studied at the individual …
