The Nature Of Resistance In Alfalfa To Wilt (Aplanobacter Insidiosum L. Mc.), George L. Peltier, F. R. Schroeder

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Alfalfa wilt was first discovered in 1924 in southern Wisconsin and northern Illinois. The causal organism, Aplanobacter insidiosum, was later described by McCulloch. Since that time wilt has been reported from most of the alfalfa-growing sections of the United States and in some states it has been responsible for a rapid decrease in the acreage of alfalfa. During the past three years a number of investigators have found that certain alfalfas are somewhat resistant to wilt, whereas others are very susceptible. At the Nebraska station the results to date indicate that all common and most variegated alfalfas are very …

Sporogenesis In Riccia Natans L., Mary Fortunata

Bachelors’ Theses

Until comparatively recent years little, comprehensive Cytological work had been done on the lower forms of plant life including the Liverworts. Cavers (1903) stated that Micheli in 1729 named a species "Hepaticae fontana" because of the supposed resemblance between the branched thallus and the lobes of the liver, and although this species was later named "Fegatella conica", the name "Hepaticae" has, since then, been applied to the whole group of Liverworts. Between 1850 and 1862 Hofmeister demonstrated "Alternation of Generations" in this group, and it was this characteristic that distin­guished them permanently …

The Morphology Of The Seminal Vesicles, Accessory Glands, And The Ejaculatory Canal Of Melanoplus Differentialis (Thomas) And An External Morphological And A Histological Study Of The Seminal Vesicles, Accessory Glands, And Ejaculatory Canal Of This Grasshopper, Wilbur T. Reierson

Electronic Theses and Dissertations

The purpose of this thesis is to record the results of an investigation, by the writer, upon the reproductive system of Melanoplus differentialis (Thomas) with special emphasis placed upon the external morphology and the histological study of the seminal vesicles, accessory glands, and the ejaculatory duct; and also to record conclusions as to the probable function of these organs.

Microfossils In An Arkansas Peat And Their Significance, Paul B. Sears, Glenn Couch

Papers in Ecology

This is an extension of a series of studies by one of the authors and his associates (1) on fossil pollen in peats of the North Central States. The purpose of such studies has been to secure information concerning the general trend of climate in postglacial time, as an aid in interpreting present vegetation.

These previous studies have indicated that postglacial climate has been largely of continental type, cool at first and later warm. Separating the cool dry from the warm dry period there appears to have been a definite although brief period of greater humidity, relative if not absolute. …

A Study Of Poverty And Dependency In Phelps County For 1931, Arthur Royal Powell

Masters Theses

"The Ozark Region of Missouri is rapidly undergoing a definite social and economic change. thru markedly improved methods of communication and transportation the eighteenth century culture of this region is being metamorphosed into a twentieth century culture. Where the Ozarker of a generation ago was a strongly individualistic frontiersman in his outlook on life, he is now in the process of becoming a citizen of a larger and more complex society. The telephone, the radio, and the concrete highway, together with the cheap automobile, have made the customs and many of the folkways and mores of the Ozark people obsolete, …

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 …

Circular No. 82 - Lamb Slaughtering And Cutting, Harry H. Smith

UAES Circulars

The old saying that "the shoemaker's wife goes without shoes" might be changed to read "the lamb raiser and feeder of the west does not eat lamb." About three-fourths of the population of the United states is east of the Mississippi River, and about 90 per cent of all the lamb and mutton produced in the United states is consumed east of the Mississippi. It has been observed, both on the farms and in towns, that a large percentage of people in the sheep sections of the west have tasted neither lamb nor mutton.

Bovine Tuberculosis, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

The development of the present-day knowledge of the tuberculoses of animals is so intimately associated with that pertaining to the human form of the disease that the latter needs to be included in the historical considerations, without which it would be difficult to view any phase of the subject in a comprehensive manner.

Tuberculosis Of Swine, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

The tuberculosis of swine constitutes a definite and very interesting section of the general problem of the tuberculoses of warm-blooded animals. No one section of this general tuberculosis problem can be adequately solved without regard to all the other sections into which it may be divided. The disease in swine is perhaps the most outstanding example which illustrates this point. This animal, extremely susceptible to tuberculous disease, but without a type of infection specifically its own, derives its infection by contact with any of the types of tuberculosis of warm-blooded animals.

Field Studies Of The Control Of The Sugar Beet Nematode. (1920-24). (Heterodera Schachtii Schmidt)., Alfred H. Bateman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The dire consequences of nematode invasion have been graphically depicted by Spiegler (1907), who says, the beet industry was at its heyday during the seventies. Nor satisfied with the land already in cultivation, the farmer plowed fertile lands along the border of the streams, wherein to grow beets, obtaining in some cases of 20 to 27 tons an acre.

The Abortion Problem In Farm Live Stock, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

This casting out of a dead or at least abnormal fetus we call abortion. It constitutes the culminating accident in a process set into motion by disease or injury. To the breeder it is its most conspicuous feature, and it's more or less constant occurrence among live stock warrants us to speak of the abortion problem. It is the purpose of this publication to lay before our Nebraska breeders such information on the subject as can be gathered from the more recent literature and from observations in the field and the laboratory.

A Founder Of American Parasitology, Joseph Leidy, Henry Baldwin Ward

Harold W. Manter Laboratory of Parasitology: Library Materials

A biographical overview of American parasitologist Joseph Leidy and his work. bron September 9, 1823, Philadelphia, Pennsylvania, USA - died 1891.

Conclusion

A detailed study of his writing justifies the statement that no one has yet adequately presented or fully elucidated Leidy's contributions to helminthology and his writing will furnish rich lead to many future workers in this field. How monumental the task of preparing a record of the full life work of this extraordinary man who in the same breath as it were, in a single letter records discoveries of far reaching import on bacteria, amoebae, worms, and fossil …

A Study Of The Tissues Of Leaves Of Certain Angiosperms, Amybelle Halbert Brady

Bachelors’ Theses

The leaves used for the study of the tissues were those of the Oleander, Ficus, Ivy, Cyperus and the Aristolochia. Portions of the leaves used were cut into rectangular pieces, about one centimeter long and one half centimeter wide, each piece including a portion of a large vein and its subsidiary veinlets. The material was placed into chrome acetic acid solution. After twenty four hours it was a shed in running water for twelve hours and then dehydrated by means of alcohol, and was then imbedded in paraffin. The sections used for the study were cut from 12 to 15 …

Some Field Instruments And Their Applications, G. W. Goldsmith

University Studies (University of Nebraska) (1888–1984)

Physiology and ecology depend for their constructive development largely upon the applications of physico-chemical concepts to living organisms and their environment, to their life processes, reactions, and interrelations. A concept is valuable biologically in so far as it can be applied and used as a tool for better understanding of the phenomena related to life. Ecology, as the study of the relations between organisms and their environment and of the interrelations of organisms, depends primarily upon the findings of physiology (Clements, 1905). But to apply physicochemical concepts and hence make them of value to the physiologist or ecologist commonly requires …

Circular No. 44 - The Agriculture Of Utah, F. S. Harris

UAES Circulars

Agriculture is so intimately related to all other industries that anything which affects the farmer reflects itself in all branches of business. The banker, the merchant, and the manufacturer must keep in touch with crop and livestock conditions of the country in order to foresee the tendencies of their own businesses. This is particularly true in a state like Utah which depends fundamentally on the products of the soil for its prosperity.

Numerous requests are received by the Experiment Station from prospective settlers living out side of the state for information concerning the agriculture of Utah. These have been kept …
