Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott

Nebraska Agricultural Experiment Station: Historical Circulars

In Nebraska, a hustling frontier state in 1887, the legislature hesitated not at all in taking advantage of the provisions of the Hatch Act, and now that fifty years have elapsed since the Station was founded, seventy-five years since the Land Grant College Act was passed and the U. S. Department of Agriculture established, and almost twenty-five years since the Agricultural Extension Service was added, it seems worth while to present a general summary of achievement within the state. The main object will be to show some of the important things that have been learned through the investigations of the …

Bulletin No. 285 - A Study Of Farm Organization By Types Of Farms In Uintah Basin, Utah, George T. Blanch

UAES Bulletins

Project 179 of the Utah Agricultural Experiment Station - "A Study of the Agricultural Resources of Utah and their Utilization" - was set up in April 1936 as a state-wide project. The object of this project was to measure by areas the basic agricultural resources of the state and to translate-the information collected into a program of more efficient use. The more specific objectives were: (1) classification of agricultural lands of Utah according to present and potential productivity and use; (2) determination of the net productive area of agricultural lands and water supply now available, or which may be developed; …

Bulletin No. 286 - Some Trends In Utah's Agriculture, Walter U. Fuhriman

UAES Bulletins

During the last two decades agriculture has been subjected to many strains and stresses- social, economic, physical, and biological. Infestations of noxious weeds and insect pests have in some instances necessitated changes in crops grown and in farming practices. Changes in precipitation have induced alternate expansion and contraction of cultivated acreage in certain areas. Improved machinery has reduced the demand for farm labor, caused shifts in crops grown and in farm population. Changes in dietary habits have increased the demand for some farm commodities and decreased the demand for others, while wide fluctuations in farm prices have wrought rapid changes …

A Century Of Scientific Exploration In Texas, Part Ib: 1820-1880, S. W. Geiser

Field and Laboratory

In the fourth volume of this journal, I published a list, with short biographical notices, of naturalists and men of science who worked in Texas from 1820 to 1880. In that paper I promised a second contribution, to deal with naturalist-collectors and students in Texas during the years 1881-1920, thus rounding out a century of scientific study and exploration in the State.

The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout

Bulletin of the University of Nebraska State Museum (1924–2023)

The rich and varied nature of the mammalian faunas of the White River Oligocene has been recognized for many years, but the exact geologic succession is only now becoming known. In these faunal assemblages the rodents and lagomorphs appear to have been important elements, perhaps numerically as abundant in the Oligocene as are these same groups at present.

Bulletin No. 282 - Pioneering In Western Agriculture

UAES Bulletins

A resume of the First Half-Century of Research 1888 - 1938 at the Utah Agricultural Experiment Station including the Biennial Report 1936 - 1938.

The Utah Agricultural Experiment Station in reaching the fiftieth year of its history can look back upon a brilliant record of achievement covering the practical as well as the more fundamental problems of agriculture in this arid state. The difficulties encountered in conquering deserts down through human history have demonstrated the mastery of man's spirit over his physical environment. Man's destiny to multiply, subdue, and replenish the earth cannot be accomplished by enjoying the fruits of …

The Organization Of Content For Agricultural Teaching In Western Kansas High Schools, Leo Virgil Wedel

Master's Theses or Doctor of Nursing Practice

The specific problem of this investigation pertains to, “The Organization of Content for Agricultural Teaching in Western Kansas High Schools." The study deals with the course of instruction in all high schools in the western half of the state teaching agriculture, except those teaching vocational agriculture. Schools teaching vocational agriculture are organized under the Smith-Hughes law. A school teaching agriculture organized under this law has a definitely prescribed course of study which does not apply to non-vocational schools. Thus, the necessity for the organization of a course of study for this latter type of school. This is a course that …

The Fresh-Water Sponges Of Wisconsin, James Russell Neidhoefer

Bachelors’ Theses

The fresh-water sponges were observed but not recognized as animals at a very early period. The early investigators thought they were plants; later workers, colonial protozoa. In 1696, Leonard Plukenet first made public mention of them; and later, in i745, Linnaeus described them as Spongia and made mention of their, "globuli". After Linnaeus the term Spongia changed many times until, in 1816, Lamarck introduced the generic name Spongilla.

The Ovary Of The Frog, Wyman O. Bergner

Bachelors’ Theses

All living organisms, under proper conditions, are able to reproduce an organism of its own kind by the natural function of its reproductive system. Except in such cases where reproduction is assexual, there are always tow individuals, male and female, which produce two elements called the ovum and spermatozoa. In the vertebrate kingdom, the sperm unites with the ovum to form the new individual. This fertilized ovum is commonly referred to as the zygote, which produces the embryo from which the new individual is ultimately formed.

In this work the ovary is studied from several viewpoints: 1) anatomical; the size, …

A Cytological Study Of The Ciliated Epithelium Of Nucula Castrensis Hinds., Dorothy Blumer

Electronic Theses and Dissertations

Ever since the latter part of the 17th century, when ciliary movement was first observed, the study of ciliated cells has been of great interest to biologists, particularly to physiologists. In 1713 Leeuwenhoek recorded some observations he made on ciliary activity, using his primitive microscope. A knowledge of the structure and function of ciliated cells is also of importance in that branch of medicine pertaining to disorders of the respiratory passages and the movement of the ovum in the uterine tubes. The bivalve molluscs have come to be the classical example for the study of ciliated cells, both because of …

The Accuracy Of Pressure Gauges Used On Household Steam Pressure Cookers, Arnold E. Baragar

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In the pressure cooker, high temperature is obtained by using steam under pressure. Since the pressure gauge is used as the indicator of temperature it is essential that the gauge register the correct pressure. Hence, this paper deals mainly with a study of the accuracy of both new and old pressure gauges used on steam pressure cookers. At the same time, four other phases were investigated: (1) the proper functioning of safety valves, (2) the various methods of sealing the lid to the cooker, (3) the proper evacuation of air from the cooker, and (4) the use of a thermometer …

A Proposed Method For Classifying And Evaluating Soils On The Basis Of Productivity And Use Suitabilities, Arthur Anderson, A. P. Nelson, F. A. Hayes, I. D. Wood

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the object of this paper to present a method for classifying and evaluating the soils as mapped in regular soil surveys on the basis of land types, which are here defined as areas having reasonably similar productivity and use suitabilities. The standards used to differentiate land types will vary according to the desired objectives, but any material difference in yield, or in practices necessary to maintain a desirable level of productivity will justify recognition of land types. The proposed procedure involves a more detailed study of the influence which soils, slope, erosion, and drainage have on specific crops …

Bulletin No. 279 - The Fruit Tree Situation In Utah, A. L. Wilson, A. L. Stark

UAES Bulletins

The fruit industry in Utah is not large when compared with the total production of the United States. The year 1935 was a favorable fruit season for Utah and yet the state produced only 0.54 percent of the United States' apple crop, 1.30 percent of the peach crop, 0.31 percent of the pears, and 3.72 percent of all cherries. Utah does, however, produce between 10 and 15 percent of all sweet cherries. Even though the Utah fruit industry represents such a small part of the national industry, a great many people of the state are dependent upon it, either wholly …

The Spleen Of The Frog, Clifford F. Moran

Bachelors’ Theses

Although we of today are living In a relatively advanced state of civilization, there still remains to be solved by man many familiar mysteries. These are found not only in the physical order but in the chemical and biological as well. It seems that the greater strides man takes toward the solution of his difficulties, the more other ones crop up to plague him. With the conquering of such deadly diseases as Diphtheria, Malaria and Scarlet Fever, man once dared to dream about a universe free from sickness. Yet today we find that three others have arisen which are causing …
