The Taxonomy Of Utah Orthoptera With Notes On Distribution, Andrew H. Barnum Jun 1952

The Taxonomy Of Utah Orthoptera With Notes On Distribution, Andrew H. Barnum

Theses and Dissertations

To an entomologist, the Orthoptera1 is in a state of confusion with respect to the available literature. Work has been done, and is now being done on the orthopteran fauna, but manuals tor identification of most species are not available for all sections or the country. Exclusive of a few lim-ited groups, Utah is among the areas that has no complete keys for taxonomic workers. In biological ivenstigations identification is essential: The species being studied must be definitely known. The primary purpose of this study, therefore, is to list the Utah Orthoptera and provide the keys necessary to their critical …


Modern Poultry Housing, Boyd Bonzer, Louis Lubinus Jun 1952

Modern Poultry Housing, Boyd Bonzer, Louis Lubinus

SDSU Extension Circulars

The new South Dakota poultry house (24’ x34’) is designed for 300 pullets, a practical size poultry project for the average South Dakota farmer. Those who desire to build for a larger flock can do so by using this plan and extending the length. It may be practical to widen the house to 30' when building for 500 or more pullets.

A Study Of Interscholastic Sports Officiating In The United States, John Martel May 1952

A Study Of Interscholastic Sports Officiating In The United States, John Martel

Health, Exercise, and Sports Sciences ETDs

The purpose of this study is to ascertain the interscholastic football and basketball sports officiating practices in the United States by (1) determining to what extent the various states certify officials, (2) what the requirements are for certification, (3) the methods of selecting officials for athletic contests, (4) the types of control the state athletic associations exert over officials regarding officials' appeals, conduct of officials, penalties for violations and settlement of disputes, (5) how the officials and the schools are rated, (6) the fees paid to the officials, (7) and the preparation made by officials who officiate interscholastic athletic contests.


Respiration Of Kidney Slices From Adrenalectomized Rats Treated With Adrenal Cortical Hormones, Miriam Landew May 1952

Respiration Of Kidney Slices From Adrenalectomized Rats Treated With Adrenal Cortical Hormones, Miriam Landew

Biology ETDs

In view of the fact that there obviously are metabolic and oxidative disturbances in the kidney caused by adrenalectomy, this investigation was attempted in an effort to obtain information concerning the following:

(1) Whether the rate of oxygen consumption of rat kidney tissue slices is a function of time; to determine whether the decreased metabolic function occurred immediately upon adrenalectomy or if an initial rise and then a falling off took place, as seemed to be indicated in the work done by Butcher (1943).

(2) Whether cortisone or desoxycorticosterone had the ability to alter oxygen consumption of kidney tissue in …


The Effects Of Epinephrine And Nor-Epinephrine On The Blood Picture In The Rat, George H. Gass May 1952

The Effects Of Epinephrine And Nor-Epinephrine On The Blood Picture In The Rat, George H. Gass

Biology ETDs

It has long been known that various stresses and stimuli elicit responses in the animal body, and since the stating of Cannon's "emergency function" (1929), the adrenal medullary hormones have been credited with exciting many of the instantaneous responses to the animal body.

The experiment was designed to determine: (1) whether nor-epinephrine has effects on the blood elements different from those seen after epinephrine treatment; (2) whether the dosage of hormone employed will affect the type of response obtained; and (3) whether the demedullated rat responds to the adrenal medullary hormones in the same pattern as the intact rat.

Estimated Feed Requirements For Livestock And Poultry, Sigurd Strangeland May 1952

Estimated Feed Requirements For Livestock And Poultry, Sigurd Strangeland

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

Rapid changes in farm practices, largely caused by labor shortages and favorable price-cost relationships, have characterized South Dakota agriculture during the last decade. These changes have raised the questions as to how well they pay. The farmer is always faced with the problem of determining the profitableness of changes in farm practices. Currently, the dollar value of irrigation, soil conservation practices, and various livestock systems of farming are important problems. How much if any of these practices will pay on a particular farm? The answer to this question depends upon the cost of the practice as compared with the benefit …

Exposure To X-Radiation Of Localized Areas Of Mammalian Skin Conditioned To Different Levels Of Metabolic Activity, James A. Belli May 1952

Exposure To X-Radiation Of Localized Areas Of Mammalian Skin Conditioned To Different Levels Of Metabolic Activity, James A. Belli

Bachelors’ Theses

There appears to be an important relationship between the overall metabolic rate prevailing in a protoplasmic system at the time of exposure to ionizing radiations and the extent of the damage effected by such radiation. It is with this issue that the present investigation is concerned.

Radiation biologists and clinical radiologists are coming to realize the importance of this problem. This increasing interest has suggested several new avenues of approach to the radiobiologist toward the elucidation of the more subtle changes occurring in protoplasmic system s exposed to radi­ation. Clinical radiology has availed itself of certain evi­dence (in a yet …

The Teaching Of Science, Sherwin Maeser

Faculty Honor Lectures

Like to teach! Whether with the expectant, half-frightened freshman, the senior, worried about his preparation now that . he must get out and meet competition, or the graduate student interested in new discoveries, I like to work with all of them.

I have been teaching a long time now. As has always been the case when one generation is thinking of turning over its work to the next, I am glad to have the opportunity to talk about some of the things that I consider important in this job of teaching.

The most varied and the most acute problems of …

Inflation And Deflation, Lyle M. Bender May 1952

Inflation And Deflation, Lyle M. Bender

SDSU Extension Circulars

Inflation and deflation are words of many different meanings. They refer to the changes in general price levels. Inflation refers generally to a situation where most prices are rising. On the other hand, deflation refers to a situation in which most prices are falling. In between these two extremes is an "ideal" situation called "stability." In our form of economy fluctuations in general price levels are normal. Inflation may be more carefully defined as a situation where the number of dollars spent increases faster than the goods and services produced. In this case, prices will rise. The opposite situation, deflation, …

Citrus-Growing In Western Australia, H R. Powell May 1952

Citrus-Growing In Western Australia, H R. Powell

Journal of the Department of Agriculture, Western Australia, Series 3

The 1952 Crop Reviewed

Western Australia in a normal year produces approximately 500,000 bushels of citrus fruits comprising 70% oranges, 20% lemons and the remainder made up mainly of grapefruit and mandarins. A general decline in production has occurred over the past three years due largely to the unfavorable seasons which have been experienced. In 1949 just over 500,000 bushels were produced. The 1950 figure was below 450,000 bushels while in 1951 approximately 375,000 bushels of citrus fruits were harvested.


Vibriosis (Vibrio Foetus Infection) Recorded In South-West Herds, J Craig May 1952

Vibriosis (Vibrio Foetus Infection) Recorded In South-West Herds, J Craig

Journal of the Department of Agriculture, Western Australia, Series 3

Vibriosis of dairy cattle was recently diagnosed for the first time in several herds in the South-West part of this State. This disease is not a new one, since Vibrionic abortion has been recognised for some considerable time in Europe and America, while within recent years it has been identified as causing abortion and sterility in cattle in the Eastern States of Australia.

Incubator Hygiene, J E. Peterson, A R. Wright May 1952

Incubator Hygiene, J E. Peterson, A R. Wright

Journal of the Department of Agriculture, Western Australia, Series 3

The rapid expansion of the poultry industry is due in no small measure to the introduction of the cabinet type of incubator. However, the widespread use of these machines in which large numbers of chickens are confined, for a period, to a very small space, has also favoured the spread of many diseases, and unless steps are taken to prevent the introduction of these diseases to the newly-hatched chickens disastrous losses are likely to occur.


Actinomycosis And Actinobacillosis, J Shilkin May 1952

Actinomycosis And Actinobacillosis, J Shilkin

Journal of the Department of Agriculture, Western Australia, Series 3

Actinomycosis and actinobacillosis, commonly known as "lumpy jaw" and "wooden tongue" respectively, are chronic infective diseases which are most commonly encountered in cattle, occasionally in pigs, and much less frequently in the other domestic animals and man. They are characterised by the presence of tumour-like swellings and exude pus containing yellow sulphur-like granules. These swellings are commonly found in or on the jawbones and tongue, but may be found on occasions, in other parts of the body such as the lungs, liver, spleen, etc.


Water Erosion Control - 2, L C. Lightfoot May 1952

Water Erosion Control - 2, L C. Lightfoot

Journal of the Department of Agriculture, Western Australia, Series 3

Earthworks are frequently used to help to control or prevent soil erosion where the adjustment of farming methods—as discussed in the March-April issue—is unlikely to be sufficient. Contour earthworks have proved extremely valuable in many cases and incidentally have caused much less inconvenience than most farmers anticipated. Landowners in need of advice on contour earthworks should get in touch with the Soil Conservation Service, Department of Agriculture, Perth, and arrangements will be made for an officer to visit their properties.

Applying Orchard Fertiliser A Handy Home-Made Aid, H S. Argyle May 1952

Applying Orchard Fertiliser A Handy Home-Made Aid, H S. Argyle

Journal of the Department of Agriculture, Western Australia, Series 3

Fertilisers such as sulphate of ammonia and nitrate of soda, being rich in nitrogen are used extensively by orchardists and market gardeners. Both these compounds are readily soluble in water and are easily carried through the soil to the rooting areas of plants and trees.


Dahlias - Lifting And Storing The Tubers, F Jackson May 1952

Dahlias - Lifting And Storing The Tubers, F Jackson

Journal of the Department of Agriculture, Western Australia, Series 3

Now that the flowering season for dahlias has finished, arrangements must be made for lifting and storing the tubers. Many losses occur each year during the dormant period and most of these are due either to carelessness or lack of knowledge. While the storage provided for dahlias during the winter months may be thoroughly satisfactory, tubers are often lost because of the treatments received by the plants during the growing period.
