The Spleen With Special Reference To Its Origin And Comparative Morphology, Morris Aaron Gilbert

Bachelors’ Theses

Throughout the ages the spleen has been an object of the most active curiosity. The opinion that the spleen is unnecessary and of no use to the individual has prevailed with an uninterrupted succession in the World in all ages. In Persia, man centuries ago, in the reign of Abouserous it was a custom to splenectomize the horses that were kept to carry the King's dispatches, in order to give them more agility and swifter feet. The great Aristotle thought the spleen to be a sort of spurious liver planted in the left side to correspond to the liver in …

The Spleen Considered With Special Reference To Its Physiology As Determined Mainly From Splenectomy, Frank X. Schuler

Bachelors’ Theses

The spleen is essentially a vertebrate organ and its steady persistence throughout the group is an indication of its importance. Comparative study shows that it has certain common structural features , which may be counted fundamental or essential. In some animals, for example, in mammals, there are found additional structures, notably lymphoid tissue and splenic muscle often regarded as secondary acquisitions.

The Relative Susceptibility Of Alfalfas To Wilt And Cold, George L. Peltier, H. M. Tysdal

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The final solution of the alfalfa-wilt problem in Nebraska probably lies in the development of resistant sorts that are winterhardy as well as productive. The relative susceptibility to wilt of 40 lots from Turkestan, 10 from France, 6 of Grimm from as many states, and 16 domestic alfalfas are reported on at this time, together with hardiness tests of a few well-known varieties and strains and the more recent introductions from Turkestan and France.

Circular No. 91 - Establishing Snow Courses And Making Snow Surveys, George D. Clyde

UAES Circulars

The major portion of the annual precipitation in the semi-arid west falls as snow. It piles up in the mountains and forms the main source of the water in the creeks and rivers draining the mountainous areas. Some of these streams flow the year around while others and intermittent, flowing only as long as the snow in the mountains lasts. The water-supply for irrigation, power development, and municipal purposes is derived largely from winter snows. A knowledge of the extent of the snow cover and its water content is, therefore, necessary for the proper utilization of this great natural resource. …

Bulletin No. 223 - Feeding Value Of Alfalfa Hay Treated With Calcium Arsenate, H. J. Frederick

UAES Bulletins

For a number of years many tons of sprayed or dusted hay have been fed successfully to livestock by stockmen interested in controlling the alfalfa weevil; nevertheless. the supposed cases of poisoning that have been reported naturally have caused concern among feeders.

Further confusion on this question has resulted from reports on studies designed to determine the effect of lead arsenate instead of calcium arsenate.

Whether the lead in lead arsenate has been a more injurious agent than the arsenic, of course, is difficult to state. Most of the experiments performed in the feeding of sprayed or dusted hay have …

Breeding Winter Wheat For Resistance To Stinking Smut (Tilletia Levis And Tilletia Tritici), T. A. Kiesselbach, Arthur Anderson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Several productive lines of hard red winter wheat which are highly resistant to both species of stinking smut (Tilletia levis and T. tritici) have been isolated from the Turkey variety. Artificial-smut and stem-rust epidemics and controlled freezing have been found useful supplements to field-performance tests. Differential reactions of the new Turkey selections and a number of hybrid selections and established resistant varieties to collections of bunt from a number of states give definite evidence of the occurrence of mild and virulent physiologic forms of both species. Certain selections have proved very resistant to some of the smut collections and …

Bulletin No. 222 - A Quarter Century Of Dry-Farm Experiments At Nephi, Utah, A. F. Bracken, George Stewart

UAES Bulletins

Utah is naturally an arid state with precipitation varying from 3.71 inches at Wendover, located in the vast desert region on the western border, to more than 40 inches on some of the mountain ranges. Desert and mountain areas and other untillable land combined total about 95 per cent of Utah's land area. The remaining 5 per cent constitutes all the land which will yield to cultivation either by irrigation or by dry-farming.

Durinog the 76 years that dry-farming has been practiced in Utah, many change in tillage practices, cropping systems, crops, and crop varieties have taken place in keeping …

Circular No. 90 - Swine Production In Utah, Harry H. Smith

UAES Circulars

During the last 20 years there has been a marked change in the type of hogs from the short-legged, wide-bodied or "hot-blood" type to a longer, somewhat more narrow-bodied, "leggier" type. For development of size in hogs they must have (1) length and depth of body, (2) length of leg, and (3) large but not coarse bones. The long-bodied rather "leggy" pig grows rapidly and makes the larger hog. While the modern hog is still a lard hog, it is not as thick and broad as were its predecessors. It is logical to assume that the hog of the future …

The Food Habits Of The Ring-Necked Pheasant In Central Nebraska, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Pheasants, including the Chinese and the so-called English pheasants, with their hybrid the ring-necked pheasant, have been introduced and established in a large area in the northern United States during the past 50 years. During the past 15 years continued importations of these birds into Nebraska, together with the rapid increase of those already established, have built up a large pheasant population in the state, estimated at more than a million birds. They have especially thrived in a block of 16 counties in east-central Nebraska. Protection was afforded them until 1927, when short open seasons were permitted in the fall …

Bulletin No. 221 - Snakes Of Utah, Herbert J. Pack

UAES Bulletins

For 17 years the late Dr. Herbert J. Pack, former Station Entomologist, made a study of the reptiles and amphibians of Utah. His original idea was to publish a comprehensive treatment of the snakes and lizards of his state, and whenever opportunity was afforded collected data on their distribution, habits, and economic importance. At the time of his death, on January 5, 1930, many notes and drawings of lizards were left; a manuscript on snakes, presented for his master's thesis to the Utah State Agricultural College in 1923, was also in his possession. Bulletin 221 contains essentially the information presented …

The Incidence Of Avian Tuberculosis In Mammals Other Than Swine, L. Van Es, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The recognition of a very widespread and intense distribution of avian tuberculosis on the farms of a wide area of the United States, as well as the involvement of a mammalian species also, brought to the foreground the question whether or not the great prevalence of poultry tuberculosis could be of importance also from a public health point of view. This phase of the problem not only pertains to the people on the farms but likewise is of fundamental importance to the consumers of poultry produce. European authors had already identified the avian tubercle bacillus in human lesions while in …

The Use Of A Small Electric Motor In Silo Filling, E. E. Brackett, E. B. Lewis

Nebraska Agricultural Experiment Station: Historical Circulars

Filling a silo 30 feet or more in height with a motor as small as five horsepower has been looked upon in general by Nebraska farmers as an impractical, if not impossible, procedure. The practice is not unheard of in other states, and certainly the possibility of avoiding the large tractor-driven cutters and the large crews will be welcomed by those who have available service from power lines.
