A Comparative Study Of The Servant Words In The New Testament, Jack Roger Reese

Electronic Theses and Dissertations

At least twelve Greek words are used at various times in the New Testament denoting some form or function of ser­vice. The development of each word in its Greek and Septua­gint backgrounds is unique; each word has a unique meaning in the New Testament. Yet the English language cannot ade­quately translate the full impact of these words as they were used by the original authors. Illumination of each term in light of its philology is necessary.

Jean Thomas' American Folk Song Festival : British Balladry In Eastern Kentucky., Marshall A. Portnoy Jan 1978

Jean Thomas' American Folk Song Festival : British Balladry In Eastern Kentucky., Marshall A. Portnoy

Electronic Theses and Dissertations

Serious musicological research initiated in the first decades of the twentieth century in America uncovered vast riches of British folk music that had been transplanted to these shores by early pioneers. In the mountains of Appalachia, traditional British ballads remained miraculously unspoiled, and distinguished researchers from Britain and America published many volumes of such songs. Jean Thomas, a legal stenographer born in eastern Kentucky in 1881, became fascinated with this phenomenon. She came to believe that an annual festival of mountain music would help ensure the survival of this art and, in 1930, she founded the American Folk Song Festival. …

Reasons Why Cows Were Removed From The Sdsu Fairy Herd 1. Discriminant Analysis To Classify Cows With Or Without Reproductive Problems, Fred Tidemann Jan 1978

Reasons Why Cows Were Removed From The Sdsu Fairy Herd 1. Discriminant Analysis To Classify Cows With Or Without Reproductive Problems, Fred Tidemann

Electronic Theses and Dissertations

One of the keys to financial success in the dairy business is the ability of management to detect herd problems and correct them instead of culling cows. It is well known that the average productive life of the dairy cow is less than 4 yr, which is short compared with her potential life. Involuntary removal of cows causes economic loss directly as a result of its effect on yearly milk production, increased replacement cost, and indirectly because the potential selection differential is reduced with premature loss of high producing cows. The degree of culling is related to important economic considerations …

Specificity Of Antisera Against Hordeum Vulgare Ribonuclease And Serological Quantitation Of The Enzyme In Tissue Extracts, Steven Bryan Hawthorne Jan 1978

Specificity Of Antisera Against Hordeum Vulgare Ribonuclease And Serological Quantitation Of The Enzyme In Tissue Extracts, Steven Bryan Hawthorne

Electronic Theses and Dissertations

Specific rabbit antisera against purified seedling RNase I from both a hardy (Dicktoo) and less-hardy (Tennessee Winter) cultivar of winter barley was obtained using a 1 mg injection schedule. Both antisera formed a single precipitin band on double immunodiffusion and immunoelectrophoresis when reacted with the homologous crude tissue extract. RNase antigen from either cultivar was highly cross-reactive with both antisera. Passive hemagglutination inhibition was used in an attempt to distinguish purified RNase from both cultivars. A consistent difference in anti-RNase serum specificity between cultivars was shown, but the difference observed by this method was not sufficient to conclude structural differences …

Methodology Development For The Study Of The Anaerobic Bacterial Flora Of Bovine Feces, Donald G. Kirsch Jan 1978

Methodology Development For The Study Of The Anaerobic Bacterial Flora Of Bovine Feces, Donald G. Kirsch

Electronic Theses and Dissertations

The intestinal bacterial flora of an animal has a considerable influence on the physiology of that animal. Some bacteria of the intestine are pathogenic and can initiate infections if they gain access to a susceptible individual. Some of the intestinal bacteria can produce potent carcinogens in vitro and can presumably do this also in vivo. Food passing through the alimentary tract of an animal is also chemically modified through the enzymatic action of the bacterial flora. The animal is also protected from some enteric infections through the antagonistic and competitive actions of the established organisms of the normal bacterial flora. …

The Effect Of Foliar Fertilization On Soybean Yield And Leaf Necrosis, Robert Jay Goos Jan 1978

The Effect Of Foliar Fertilization On Soybean Yield And Leaf Necrosis, Robert Jay Goos

Electronic Theses and Dissertations

The soybean (Glycine max (L.) Merrill) is a very important world crop. The seed is rich in both protein and oil, making it a valuable human food resource. Many scientists believe that there are physiological barriers preventing increased soybean yields. Any agronomic discovery that would consistently increase soybean yields would be important to world food production. One possible yield barrier in soybeans concerns the mineral nutrition of the plant during the seed-filling stages of growth. During this period of growth, translocation of N, P, K, and S from the plant foliage to the developing seed occurs, accompanied by a virtual …
