The Effect Of Prostaglandin F2-Alpha On Synchronizing Estrus In The Ewe, L Dean Churchill

Electronic Theses and Dissertations

Synchronization of estrus has been attempted by using hormone or hormone-like substances to bring females into estrus simultaneously. The objective of a synchronization program is to manipulate the reproductive process so that all females may be bred during a short pre-defined interval with normal fertility at this breeding. The concept of estrus control and synchronization is intriguing, offering the possibility of more uniform offspring, better use of facilities and labor, concentration of parturition and, in particular, the better utilization of outstanding sires through artificial insemination. The breeding season is the period during which ewes come into heat and will receive …

Applications Of X-Ray Single Crystal Diffraction To Structure Determination, Bih- Lian Huang Jan 1980

Applications Of X-Ray Single Crystal Diffraction To Structure Determination, Bih- Lian Huang

Electronic Theses and Dissertations

X-ray diffraction methods frequently give unequivocal answers about structure in the solid state. Single-crystal X-ray diffraction methods have been used for structure determination since the 1930’s. The primary aim of a crystal structure analysis by X-ray diffraction is to obtain a detailed picture of the contents of the crystal at the atomic level. Once this information is available, and the positions of the individual atoms are known precisely, one can calculate interatomic distances, bond angles, and other features of the molecular geometry that are of interest, such as the planarity of a particular group of atoms, the angles between planes, …

Effects Of Isotonic Training, Isokinetic Training And Jumping Practice On The Vertical Jump Performance Of College Age Women, Teri Helling

Electronic Theses and Dissertations

There has been very little research completed in the area of weight training for women. Many women have weight training facilities and equipment available to them, but for many reasons do not take advantage of it. There are many misconceptions of weight training that are of concern to the female, such as; loss of flexibility, developing large, bulky muscles and traits of masculinity. A problem also arises in the knowledge and proper use of equipment. Until the present time, the two main concepts of resistive exercise have been isotonic and isometric. In 1966, Ferrine pioneered the first isokinetic exerciser. Isokenetic …

The Effectiveness Of Aeration And Potassium Permanganate Oxidation And Filtration On Removal Of Iron And Manganese From Ground Water, Steven J. Quail Jan 1980

The Effectiveness Of Aeration And Potassium Permanganate Oxidation And Filtration On Removal Of Iron And Manganese From Ground Water, Steven J. Quail

Electronic Theses and Dissertations

The United States Public Health Service (USPHS) established water quality standards in 1946 and revised them in 1956 and 1962. In these standards the maximum recommended concentrations of iron and manganese were 0.03 and 0.05 mg/l respectively. Because trace amounts of these elements are essential for proper nutrition of both plants and animals, the recommended limits are not based on any physiological or environmental considerations. Rather, the presence of iron and manganese in water is objectional because the precipitation of these metals alters the appearance of the water, turning it a turbid yellow brown to black.

Potential Industry Possibilities For South Dakota Indian Reservations, Yus Rusman

Electronic Theses and Dissertations

Research studies covering manufacturing growth in more than 245 non-metropolitan communities (ones with less than 50.000 population) across the U.S. indicate that new industries may generate employment and earnings in communities where the industries are located, but net fiscal gains to local governments and school districts may be more modest. And, in some cases, elements of the local public sector may incur cost increases exceeding tax and other revenue increases. Dobbs felt that communities should not be discouraged by these findings. Instead they should invest some time and effort in examining two questions. The first question pertains to the examination …
