Cost Analysis Of Precast Prestressed Composite Pavement On U.S. Highway 14-Bypass, Wayne R. Haug

Electronic Theses and Dissertations

Because of the increase in heavy truck traffic, the need has developed for a stronger pavement to carry increasing wheel loads. These loads have usually resulted in thicker pavements which increases the cost. In some parts of the country the aggregates needed for pavements are scarce, making it necessary to transport the aggregates over long distances to the construction site. This longer haul increases the pavement cost and makes it necessary to investigate other methods of construction. A recent pavement development utilizes prestressed concrete. Prestressed concrete is composed of concrete prestressed with high strength steel. Concrete has a high compressive …

A Time-Lapse Photography Study Of Free Stall Housing For Dairy Calves, James L. Reeves

Electronic Theses and Dissertations

As a principal means of herd replacement and expansion, the dairy calf is vital to the success of a dairy enterprise. High mortality rates among dairy calves, frequently as high as twenty percent, are very costly to the dairyman. Besides paying the high cost of losing a calf, the dairyman must find a replacement for the animal. Obtaining a herd animal from outside sources involves the risk that the replacement may be of lower quality than was the lost calf. Through careful selection of animals and a well-planned breeding program, a good farm manager will find raising his own replacement …

Computer Evaluation Of Error-Correcting Codes For Pcm Telemetry, William W. Goddard

Electronic Theses and Dissertations

Communication in a broad sense is simply transferring information of some sort from one point to another, usually by means of electrical signals. The sender and the receiver of the information may be either man or machine. If the information to be transferred is in a numerical form, the system is called a Digital Data Communication System. This type of system is usually employed in machine-to-machine communication, but may be applied to transferring other types of information by first converting that information into a numerical (digital) form. In today's typical Digital Data Communications, the numerical data is converted to binary …

Wedge Flows Of Power-Law Fluids, Joseph H. Cothern Jan 1969

Wedge Flows Of Power-Law Fluids, Joseph H. Cothern

Electronic Theses and Dissertations

Many solutions exist for the laminar boundary-layer flow of Newtonian fluids. This is verified in literature by Schlichting. However, some fluids do not obey the Newtonian postulate that the stress tensor is directly proportional to the rate of deformation tensor. It is as likely, in fact, that non-Newtonian fluids could be pumped into an industrial complex as the more common Newtonian fluids. This is partly due to the growing use of synthetics and petroleum products in modern day living. The use of non-Newtonian fluids, however, does not have to be limited to problems of internal flow. The fluid in the …

Evaluation Of The Ovulated Follicle Technique As A Means Of Determining Pheasant Production, C. Denis Allen Jan 1969

Evaluation Of The Ovulated Follicle Technique As A Means Of Determining Pheasant Production, C. Denis Allen

Electronic Theses and Dissertations

A study of the ovulated follicle technique for determining egg production in pheasants was conducted during 1967 - 1969. Evidence indicated collection of wild hens for follicle counts should be between 5 and 14 weeks after cessation of laying. Questionable follicles encountered should be considered ovulated follicles and included in the counts. Most questionable follicles were believed to originate from ovulated atretic follicles that were harder to identify because of their particular stage of regression. The influence of freezing on atretic follicle counts was studied, and no adverse effects were found. A technique was developed for selectively staining atretic follicles. …
