The Potential Generated In A Falling Meteorite, John D. Boon

Field and Laboratory

When a material body moves across a magnetic field a potential difference is generated between the opposite sides of the body. The value of this potential difference depends directly upon the velocity, the strength of the magnetic field that is being cut, and upon the dimensions of the body.

Role Of Seedlings In Recovery Of Midwestern Ranges From Drought, J. E. Weaver, Irene Mueller

Department of Agronomy and Horticulture: Faculty Publications

An extensive survey of the degree of deterioration of midwestern ranges was made in 1939 (Weaver and Albertson, '40). Decreases in the basal cover of the grasses from extreme drought, overstocking, and damage by dust were appalling. Basal cover of the native grass had decreased to 1 percent in one-fourth of the ranges examined and it was 21 percent or more in only 16 percent. Little, if any, improvement occurred during the following year; instead certain large areas suffered distinct losses as a result of severe late summer drought. The perennial grasses over large areas in southwestern Kansas, for example, …

Vegetation Of The Northern Part Of Cherry County, Nebraska, William L. Tolstead

Conservation and Survey Division: Faculty and Staff Publications

Agricultural practices in the Great Plains of North America are now in a period of adjustment from a traditional agriculture initiated by pioneer farmers to a grazing economy based upon potentialities of climate and soil. The attainment of a proper system of land use has been retarded in many localities by the lack of definite information concerning the vegetation and its indicator significance. In this study of the vegetation of Cherry County, Nebraska, the interrelations between the plants and their environments are discussed, the dominant species are described, and changes in grasslands caused by seasons, grazing, and climatic cycles are …

Tax Situation Hand County, Gabriel Lundy

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

This county pamphlet is intended to provide local information about taxes which would otherwise be difficult for citizens to find, and to present it in a readily useable form.

Alfalfa Breeding, H. M. Tysdal, T. A. Kiesselbach, H. M. Westover

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Interest in the principles of alfalfa breeding has increased greatly with the growing "forage consciousness" of the country at large and the more specific interest developed through cooperation in the Alfalfa Improvement Conference. As is true of many other forage crops, information on the breeding behavior of alfalfa is meager. During the past few years, however, the genetics and principles of reproduction of this crop have come to be better understood and it is the purpose of this paper to bring together the available information pertaining to the improvement of alfalfa and to add certain suggestions with respect to future …

Bulletin No. 301 - Economic Analysis Of The Weber Central Dairy Association, Walter U. Fuhriman, Harold H. Culter, W. Preston Thomas

UAES Bulletins

At the request of the dairymen in the Ogden milk shed the Department of Agricultural Economics, Utah Agricultural Experiment Station, made an analysis of 162 dairy farms in the Ogden area for the years 1937, 1938 and 1939. The study covered the entire farm business and a detailed analysis of the dairy enterprise.

Since production of dairy products is closely associated with, and is affected by, the marketing institutions which provide outlets for these products, an analysis of marketing phases was made through a study of Weber Central Dairy Association , one of the larger dairies of the area . …

Leoti For Starch, R. L. Cushing

Nebraska Agricultural Experiment Station: Historical Circulars

The popular forage crop, Leoti sorghum, has possibilities of becoming an important special purpose grain crop for industrial utilization. Investigations of the Department of Agricultural Chemistry have shown that starch manufactured from the waxy grain of this variety has properties similar to those of tapioca starch. Tapioca starch, made from the roots of the cassava plant, has been imported by the United States to the extent of 175,000 tons annually. The chief source of supply, the Dutch East Indies, has been eliminated by the war, and domestic substitutes are being urgently sought by the industry. This type of starch is …

A Study Of The Sanitary Quality Of Drinking Water In Rural Districts Of Crawford County, Kansas, Kenneth Andrew Mcclure

Electronic Theses & Dissertations

This study involved the testing of seventy-six wells and thirty cisterns in representative rural districts of Crawford County, using methods specified by the American Public Health Association in the eighth edition of Standard Methods for the Examination of Water and Sewage.

The results of the tests showed that only fourteen of the 106 wells and cisterns tested did not yield Escherichia coli. Of the ninety-two polluted drinking water supplies twenty-seven were from cisterns, while sixty-five were from wells. Of these sixty-five only five of the fourteen deep wells in the group showed evidence of contamination.

These findings seem to warrant …

The Histology Of The Duodenum Of Thamnopsis Sirtalis, Harvey William Lyon

Bachelors’ Theses

The problem directly concerned is the histological study of the duodenum In Thamnopsls sirtalls, the common green or garter snake. The gross anatomy has been worked out In Reptilian forms and shows great variations, whereas very little work has been performed in the histology of the digestive organs. Some study has been made In other Reptilian forms such as the lizzard family but the knowledge of their histological structure is limited. Therefore if the gross anatomy differs in various forms, so may the histology differ also. It is the problem then of this thesis to investigate this subject and determine …

An Experimental Attempt To Modify The Sex Ratio Of Drosophila Melanogaster, Herman Weingrod

Bachelors’ Theses

Sex control has been defined as the science of producing male or female offspring at will by artificial means. Because of the far reaching consequences of such a technique, man has always had a strong desire to control the sex of his offspring. The ancient Egyptians attempted it by means of magic, while the old Hebrew Talmud offered suggestions for its practice based on practical experience. The problem as such forms part of the folklore and superstition of many ancient races and peoples.

The Anatomy Of The Stem, Root And Leaf Of Dennstaedtia Cicutaria Moore, William J. Weishar

Bachelors’ Theses

The work in plant anatomy up to 1874 was brought together and added to by De Bary (1884) in his memorable work, the Comparative Anatomy of the Vegetative Organs of the Phanerogams and Ferns. Several years later, Van Tieghem (1886) presented the groundwork for the stelar theory to explain the fundamental structure of the stem and root axis of the plant. Since that time the anatomy of the Pteridophytes has been the object of Increased interest and study.

The Effect Of Organic And Inorganic Substances Upon The Enzymatic Activity Of Papain Using Gelatin As A Substrate, Raymond A. Sklencar

Bachelors’ Theses

In the science of enzymology many hitherto unknown facts have been discovered. Among these are the facts which show that certain substances or conditions will accelerate, inhibit, or poison an enzyme reaction. Thus, heavy metals, oxidizing agents, etc., will prevent the enzyme from working at a normal rate or even "kill" the enzyme completely. Again, certain materials or co-enzymes will speed up and increase the enzyme power of a substance.

A Study Of Origins And Ecological Features Of Hardy, Cultivated, Herbaceous Plants Of Milwaukee, Wisconsin, Dorothy Elaine Witheck

Bachelors’ Theses

Gardeners have always been interested in herbaceous plants, chiefly because of their beauty and usefulness. As a result of the great popularity, a large number of attractive varieties have been produced through centuries of' cultivation, selection and breeding. Very early agricultural and medical demands stimulated an interest in the plants, and as early as 372-287 B.C. Theophrastus, a pupil of Aristotle, described about 460 cultivated plants and classified them as herbs, undershrubs, shrubs and trees. Much of the work accomplished by the ancient Greeks was lost and it was not until the sixteenth century that renewed enthusiasm for the study …

A Study Of The Anatomical Structure Of The 6mm Wall-Eyed Pike, Richard E. Roche

Bachelors’ Theses

The following is a detailed study of the 6 mm Wall-eyed Pike. The organs and organ systems are presented and discussed in the same serial order that they appear in the embryo beginning at the anterior end and proceeding posteriorly. There has apparently been very little work done on the embryology of the Wall-eyed Pile for the literature contains only one article that is even closely related to this problem. In 1890 Reighard made a general study of the development of the Wall-eyed Pike from the time of fertilization to the fully grown adult. He did not, however, make any …
