The Grand Prairies Of Texas, Frank Bryan

Fondren Science Series

Welcome to the Grand Prairies of Central Texas. They were first so called by that grand old man of early Texas geology, Dr. Robert T. Hill. These prairies offer no spectacular, breath-taking landmarks to the viewing eye. They offer only a broad vista of rolling prairie hills. Yet this can be a thrilling vista, once you know the details of its history back into remote antiquity.

The Effects Of Intraperitoneal Injections Of Methylene Blue On Sarcoma 37 In Mice, Jennifer Sullivan

Student Scholarship

This research investigates the quantitative effects of methylene blue on the growth of transplanted sarcoma 37 in Swiss mice. While some previous literature suggested that oral administration of this thiazine dye could inhibit certain carcinomas, this study focuses on the results of direct intraperitoneal injections. The experimental process involved injecting mice with varying concentrations of the dye and allowing a nine-day growth period before removing the tumors for microscopic analysis. The primary metric for determining growth effects was the mitotic count, which involved averaging the number of dividing cells across multiple sections and fields for each tumor. 

The results indicate …

The Effect Of Common Contaminants On Cheese Starter, Ivan R. Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Starter is the "heart" of the cheese making industry. Only by proper handling of starter can good quality cheese be made. The economic loss from contaminated starter may prove disastrous to a cheese plant if proper corrective measures are not taken.

Milk usually contains a variety of bacteria. Under plant conditions some of these bacteria get into the mother starter or bulk starter unless extreme caution is used. Comparatively little is known about how one organism influences another when grown in milk. This problem is important in the cheese industry.

Use Of Dk Cheese Starter In Manufacture Of Commercial Cheddar Cheese, Carl Anthon Ernstrom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several months' curing time is needed to give cheddar cheese the desirable flavor demanded by the market. The exact length of time required for curing depends upon the flavor intensity desired, but the curing process is always costly and time-consuming.

The practice of making cheddar cheese from pasteurized milk is now common throughout the industry. Many progressive cheese factories are pasteurizing their milk and enjoying the consequent benefits from a higher quality product. Although pasteurization has eliminated many of the quality problems in cheesemaking, it has resulted in even slower curing cheese.

Much of the cheese research now being carried …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Importance of project:

In recent years many antibiotics have come to the foreground as a treatment for mastitis. Aureomycin is one of the more recent antibiotics that has been used for this purpose.

Aureomycin has been reported to be successful in curing some types of mastitis, but milk produced by cows that have been treated with Aureomycin does not act normal in the cheese manufacturing process. The most noticeable effect in milk from cows treated with Aureomycin has been slow or complete cessation of acid production by bacteria in cultured dairy products; this has been especially true in the cheese …

Application Of Pheasant Census Methods In Cache County, Utah, Gordon L. Zorb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An inventory of the stock on hand is a basic step in management. This is true whether the field be business, land, or wildlife management. It is a marginal business man who ignores the basic step of inventory. In the history of wildlife management, however, it has not been unusual to find the cart before the horse. This is not to say that the wildlife manager is, or has been, marginal. His business was inherited ready-made, but often in a bankrupt condition. The problems were there, but not the background of records, techniques, or methodology to cope with them. Often …

The Opercular Bone As An Indicator Of Age And Growth Of The Carp Cyprinus Carpio Linnaeus, William J. Mcconell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As part of an investigation of the non-game fish resources of Utah, a study of the age and growth rate of the carp was instituted. A preliminary investigation indicated that the opercular method was superior to several other methods of determining age and growth in the carp. Age and growth were calculated from the opercular bones of 330 carp collected at Ogden Bay Refuge in 1950-51. Distances to annuli were measured directly. The relationship between the posterior radius of the opercular bone and the standard length of the carp was curvilinear. Past growth was calculated with a logarithmic nomograph. Expected …

The Desert Shall Blossom As The Rose, D. Wynne Thorne

Faculty Honor Lectures

IRRIGATION AGRICULTURE has not received attention commensurate with its significance in either ancient or modem times. Although most ancient civilizations depended on irrigation for their very existence, one can consult volume after volume of history only to find irrigation scarcely mentioned. To the agricultural specialist the great challenge and the strength and weakness of irrigation agriculture is not in constructing Boulder Dams nor in planning winding canals and syphons to carry water from the Columbia River to California. The critical point is on the farms where water is applied to the soil and crops are harvested. There the real battles …
