The Effects Of Penicillin On E. Rhusiopathiae Infected Pigeons, L. Van Es, J. F. Olney, I. C. Blore

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Advantage was taken of an opportunity to study the effects of penicillin on Erysipelothrix rhusiopathiae, the causative organism of swine erysipelas. Owing to the fact that swine cannot readily be infected with erysipelas by artificial methods, pigeons which are highly susceptible to the disease, were selected to serve as experimental animals. It was the purpose of these studies to ascertain whether or not the swine erysipelas bacillus is sensitive to the drug and incidentally to determine the possibility of finding application of penicillin in the treatment of swine.

Carotene Content Of Native Nebraska Grasses, I. L. Hathaway, H. P. Davis, F. D. Keim

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The carotene content of twenty-four grasses native to Nebraska were determined at approximately monthly intervals from June to November. While the carotene concentration of most of the grasses was moderately high during the growing season, it declined to a rather low point by late November. With the exception of Switchgrass, Hairy Grama, Little Bluestem and Prairie Dropseed, all of the grasses contained enough carotene to supply the needs of range cattle until late November. However, only eighteen of the grasses still contained enough carotene by the latter part of September to furnish the carotene required by dairy cows. Even as …

Injury And Death Or Recovery Of Trees In Prairie Climate, F. W. Albertson, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Several years of decreasing precipitation initiated the 7 years of drought. By midsummer of 1934 it vas clear that the prairie region of the Middle West was undergoing the greatest drought since the beginning of its recorded weather history. The 12 months following June, 1933, was the driest weather period ever recorded not only for the Dakotas, Minnesota, Nebraska, Iowa, Illinois, and Missouri, but also drought in Kansas, Oklahoma, and Colorado was very severe (Kincer 1934). This intensely dry period, as well as those in several of the following years was accompanied by record-breaking temperatures, extremely low humidities, and exceptionally …

Bulletin No. 321 - Utah Housing In Its Group And Community Aspects, Joseph A. Geddes, Carmen D. Fredrickson

UAES Bulletins

The method employed in this study is to select a comparatively important segment of living--housing--for careful appraisement with the purpose of comparing different groups and localities with respect to it. Comparisons are made (1) between Utah and other states, (2) between counties of Utah, and (3) between four Utah communities. The data include the house, home conveniences, the automobile, the streets ad joining the house, newspapers, magazines, books, and connection with water, sewer, power and telephone lines. The segment is thus not small. The groups are segregated by the vocation, farm and nonfarm, from which the living is made. The …

A Comparative Study Of Directed Laboratory And Lecture Demonstration As Methods Of Instruction In Teaching Botany To High School Students, M. Lucida Vorndran

Master's Theses or Doctor of Nursing Practice

A controlled investigation of green plants as the most important food factories of the world has been made in order to contribute more information upon the issue. Stated more specifically, the problems of this experimental study were the following: 1. To determine which of the two methods, if either, is superior as a procedure for learning. 2. To determine whether laboratory experiments are more effective than lecture-demonstration in training students to think clearly, to correlate and retain facts; and finally, to draw logical conclusions. 3. To determine, if possible, which method stimulated the greater amount of pupil interest.

Tertiary Coniferous Woods Of Western North America, George F. Beck

All Faculty Scholarship for the College of the Sciences

Almost four decades have elapsed since Platen (1908), the German paleobotanist, published his report upon the fossil woods of the western United States. Since then no over-all treatment of these materials has been attempted. although Platen overlooked the Pacific Northwest with its abundance of Tertiary petrified woods. The purpose of this paper is to bring knowledge of the western coniferous woods of the Tertiary up to date. In this effort the writer recognizes that much of this information has been accumulated incidentally in the study of the Russell Petrified Forest series of central Washington, and that it is not as …

Sources Of Amylase-Producing Bacteria, George L. Peltier, L.D. Beckord

Papers in Microbiology

In the search for bacteria possessing high amylolytic activity, some thousand or more isolates were screened on soluble starch agar and the extent of their activities determined qualitatively by the loss of medium response to Lugol's iodine solution. The selected isolates were then grown on a liquid wheat bran medium and the resulting starch-dextrinizing activity measured quantitatively. No attempt was made to determine the properties of the various amylases. The primary purpose of this report is to point out the original sources from which the isolates were made and to correlate the nature of the substrates with the extent of …

Bio-Ecology On A Mixed Prairie Near Hays, Kansas, H. Leo Brown

Master's Theses or Doctor of Nursing Practice

A survey of the activity of wild animals in connection with range conditions and range management is greatly needed in western Kansas. To have a well-managed range one should have an understanding of the ecological factors which benefit or deplete the native vegetation that is essential for production of livestock. The impact of grazing, and the effect of changes in edaphic and atmospheric environment on the prairie have further emphasized the importance of a cover of grass in preventing erosion.

Collectors Of Pleistocene Vertebrates In Early Texas. I. William P. Huff (1811-86), S. W. Geiser

Field and Laboratory

Much of the ·work of exploration for Pleistocene vertebrates has been done in the last sixty years; but some was done at a period as remote as the first days of the Republic of Texas. William P. Huff, merchant of San Felipe, the summer of 1837 found proboscidean and other remains at the shoals of the Brazos, a few miles below San Felipe. He built up a collection.

John Wright Glenn (1836-92), Early State Geologist Of Texas, S. W. Geiser

Field and Laboratory

The second State Geological Survey of Texas (the "Glenn­ Buckley survey") owed its establishment to an Act approved August 13, 1870 (supra). Over two years elapsed, however, before a state geologist was named. Finally, on March 31, 1873, Governor Edmund J. Davis appointed J. W. Glenn State Geologist. Charles Edward Hall of Albany, N. Y., was his assistant. This office Glenn held until March 6, 1874, when he resigned.

Reciprocal Reinforcement, Its Limitations, And The Freedom Of Man, John D. Boon

Field and Laboratory

As a farmer boy, I often observed that when a litter of pigs was born, some of them were stronger than others, and these stronger pigs, because of their superior power, were able to get more milk from their mother than the weaker pigs. Of course this meant that the stronger pigs grew faster than the weaker; and the faster they grew, the more milk they were able to get, and the more milk they got, the faster they grew. It might seem that this cycle would be endless. It had, however, its limitation; for there is a limit to …

Sophia Hammann, An Early Texas Midwife And Herbalist, Eula Whitehouse

Field and Laboratory

About 1874, a little old woman came with her husband, William Hammann, to Rabb's Prairie in Fayette County. She had studied and practiced midwifery and herb medicine for many years in her native Alsace-Lorraine. Since at that time there were but few physicians in the county, and since among the German and Czech populations employment of a physician (Arzt) was infrequent, many people, were grateful for her care and services.

A Seven-Year Quantitative Study Of Succession In Grassland, J. E. Weaver, W. E. Bruner

Department of Agronomy and Horticulture: Faculty Publications

The study of plant succession has contributed more than any other single line of investigation to a deeper insight into the nature of vegetation. Earlier studies of succession, especially in grassland, were largely those of the primary sere. But with the utilization of the prairies for grazing, and the abandonment of submarginal land after a short period of cropping, numerous investigations of secondary successions were made. The earlier studies have been discussed by Clements (1916) in "Plant Succession." Sampson's plant succession in relation to range management appeared in 1919. Many of the more recent investigations of subseres in grassland and …

Extent And Longevity Of The Seminal Roots Of Certain Grasses, J. E. Weaver, Ellen Zink

Department of Agronomy and Horticulture: Faculty Publications

Grasses possess two distinct root systems. The primary or seminal root system begins development immediately upon the germination of the seed and consists of one to several main roots and their branches, the number varying with the species. The young plant is entirely dependent upon this primary root system for water and soil nutrients. Later, especially during the period of tiller production, a secondary or nodal root system develops from the lower nodes of the parent culm and from the tillers. The seminal roots are often designated as temporary in general texts and even in special books on grasses. Hitchcock …

The Effects Of Oxygen, Carbon Dioxide, And Pressure On Growth In Chilomonas Paramecium And Tetrahymena Geleii Furgason, D.M. Pace, R.L. Ireland

Papers in Microbiology

The effects of oxygen, carbon dioxide, and pressure on animal organisms have been widely studied, but most of the investigations in this field concern chiefly the effects of extreme, especially high, atmospheric pressures on blood changes, respiration, length of life, etc., in Vertebrates.

Very few detailed observations have been made on the relation between oxygen tension or carbon dioxide tension and growth in Protozoa. The few investigations that have been carried out are concerned primarily with the effect of these gases on respiration although some observations have been made on the relation of aerobic and anaerobic conditions and growth in …

The Plains Garter Snake, Thamnophis Radix, In Ohio, Roger Conant, Edward S. Thomas, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The announcement that Thamnophis radix, the Plains garter snake, occurs in Ohio and is not rare in at least one county, will surprise most herpetologists and students of animal distribution. Since the publication of Ruthven's monograph on the genus (1908), almost all authors have followed his definition of the range of this species, giving eastern Illinois as its eastern-most limit. Ruthven (p. 80), however, believed that radix very probably would be found in western Indiana, a supposition since substantiated by Schmidt and Necker (1935: 72), who report the species from the dune region of Lake and Porter counties.

A Survey Of Fruit Production And Consumption In South Dakota, 1944, Agricultural Experiment Station, South Dakota State College

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

The importance of an adequate supply of fruit in the diet has been stressed in recent years. Nutrition and production specialists have long believed that both the production and consumption of fruit have be too low in South Dakota. Climatic and transportation problem in South Dakota, often make it difficult for some families, particularly in the western part of the state, to grow or purchase adequate supplies of fruit throughout the year. The lack of information on the quantities of fruit produced and consumed in South Dakota prompted the State Nutrition Committee to make a state wide study during 1944. …
