Relation Of Hardpan To Root Penetration In The Great Plains, J. E. Weaver, John Crist Jan 1922

Relation Of Hardpan To Root Penetration In The Great Plains, J. E. Weaver, John Crist

Department of Agronomy and Horticulture: Faculty Publications

During the excavation of root systems of native and crop plants through- out the Great Plains region during the past five years (Weaver, 1919,1920, 1922) contact has been made in more than thirty fields with the so-called hardpan. Such a layer of soil underlies much of this area of low rainfall, at depths varying from 15 inches to 3 feet. It varies from 8 inches to over 1.5 feet in thickness. In connection with studies on the physical and chemical composition of the soils and their seasonal water-content under natural and cropped conditions, a more detailed study has been made …

Genetic Interrelations Of Two Andromonoecious Types Of Maize, Dwarf And Anther Ear, R. A. Emerson, Sterling H. Emerson Jan 1922

Genetic Interrelations Of Two Andromonoecious Types Of Maize, Dwarf And Anther Ear, R. A. Emerson, Sterling H. Emerson

Department of Agronomy and Horticulture: Faculty Publications

Attention was called by Montgomery (1906)to the occasional appearance

of perfect flowers in the staminate inflorescence of maize and similar

cases were reported by Kempton (1913). Montgomery (1911) described

with illustrations a true-breeding type of semi-dwarf dent maize, the ears

of which were perfect-flowered. Perfect-flowered maize was described

and illustrated also by Blaringhem (1908, pp. 180-183). East and

Hayes (1911, pp. 13, 14) noted and illustrated a perfect-flowered sweet

corn. Weatherwax (1916, 1917) showed that typically pistillate

flowers of maize exhibit in microscopic sections the rudiments of stamens

and that staminate flowers show rudiments of pistils.


The Physiology Of The Respiration Of Fishes In Relation To The Hydrogen Ion Concentration Of The Medium, Edwin B. Powers Jan 1922

The Physiology Of The Respiration Of Fishes In Relation To The Hydrogen Ion Concentration Of The Medium, Edwin B. Powers

Papers in Systematics and Biological Diversity

Within recent years much has been added to the knowledge concerning the mechanism of the respiratory function of the blood. Haldane and Priestley (1905) have shown that, at least in the higher animals, the respiratory movements are affected by the carbon dioxide tension of the arterial blood. It has been shown definitely (Hasselbalch, 1912 and citations) that the exciting agent is the hydrogen ion concentration of the blood bathing the respiratory center.

Krogh and Leitch (1919) undertook to study the respiratory function of the blood of fishes in view of the knowledge of the influence of temperature upon the dissociation …


The Flat-Headed Apple-Tree Borer, Fred E. Brooks Jan 1922

The Flat-Headed Apple-Tree Borer, Fred E. Brooks

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The flat-headed apple-tree borer, a serious orchard pest throughout the greater part of United States, is found from the Atlantic to Pacific and from Florida and Texas to Canada.

The larva, or grub, of this insect (which in the adult stage is a medium-sized beetle) bores in the bark and wood of a great variety of trees, but is best known as an enemy of apple, pear, peach, and other cultivated fruit trees. Its depredations are felt in almost every locality where orchards have been planted.

Fortunately, this borer almost invariably confines its attacks to the sunny sides of trees …

New Species And Collections Of Arrhenuri: 1921, Ruth Marshall Oct 1921

New Species And Collections Of Arrhenuri: 1921, Ruth Marshall

School of Biological Sciences: Faculty Publications

The genus Arrhenurus, the largest group of the water mites, continues to yield new material from collections in lake regions. The new species described in this paper came from regions as far apart as Canada and China; while additional notes on already described species are based on material secured in several states of northeastern United States, some of them from new localities. Through the kindness of Professor N. Gist Gee, of Soochow University, material was secured for the description of new species from China. Professor Frank Smith and Dr. H. R. Vancleave, of the University of Illinois, were good enough …


The Spirit Of The Common Law, Roscoe Pound Aug 1921

The Spirit Of The Common Law, Roscoe Pound

Nebraska College of Law: Faculty Publications

These lectures speak in large part from the second decade of the present [20th] century; and they show the faith in the efficacy of effort and belief that the administration of justice may be improved by conscious intelligent action which characterized that time. The recrudescence of juristic pessimism in the past three years has not led me to abandon that point of view. At the end of the nineteenth century lawyers thought attempt at conscious improvement was futile. Now many of them think it is dangerous. In the same way the complacent nothing-needs-to-be-done attitude of Blackstone, who in the spirit …

Vegetation Mapping, Paul B. Sears Apr 1921

Vegetation Mapping, Paul B. Sears

Papers in Ecology

The value of accurate maps of native vegetation as a basis for very practical generalizations can not be questioned. It is obvious that an essential condition for getting accurate maps of large areas is the existence of precise maps of smaller component ones. At present very few precise local maps are available, but it is to be hoped that botanists throughout the country will begin to supplement the efforts of a few of their number who are doing map work of permanent and general' value.


The Regional Adaptation Of Corn In Nebraska, T. A. Kiesselbach, F. D. Keim Apr 1921

The Regional Adaptation Of Corn In Nebraska, T. A. Kiesselbach, F. D. Keim

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this investigation was to determine some of the factors involved in the regional adaptation of corn. The procedure has been to make a comparative study of native corn types, known to be locally adapted to various regional areas in Nebraska through long growth there. The work has been confined to the single species group - Zea mays indentata. No one variety of a common source is grown throughout the state, and therefore it has been impossible to keep within a single variety. It would appear that the data should indicate morphological and histological plant characteristics involved …


The Nebraska Tractor Law And Rules For Official Tractor Tests, O. W. Sjogren, E. E. Brackett, C. W. Smith, F. R. Nohavec Apr 1921

The Nebraska Tractor Law And Rules For Official Tractor Tests, O. W. Sjogren, E. E. Brackett, C. W. Smith, F. R. Nohavec

Nebraska Agricultural Experiment Station: Historical Circulars

The Nebraska Tractor Law, which became effective July 15, 1919, was enacted to encourage the manufacture and sale of improved types of tractors and to contribute to a more successful use of the tractor for farming. It was thought that the best method of accomplishing these objects would be to require a tractor of each model sold in the State to be tested at the State University and to have the results of these tests made public.


A New Blood Fluke From Turtles, Henry Baldwin Ward Mar 1921

A New Blood Fluke From Turtles, Henry Baldwin Ward

Harold W. Manter Laboratory of Parasitology: Library Materials

For several years an interesting trematode has been under observation in the laboratory here. It occurs in various species of turtles, and was first discovered in some material shipped in from the south for class work. Peculiar importance attaches to the fact that it is a species inhabiting the circulatory system, and in fact it shows a relationship to the blood-inhabiting flukes of man which has become more clearly evident as the observations have accumulated. Since the material is easily obtained, it will afford perhaps the best opportunity available in this country for the laboratory study of forms adapted to …


Variation In Taraxacum, Paul B. Sears Feb 1921

Variation In Taraxacum, Paul B. Sears

Papers in Ecology

To the editor of Science: Since several species of Taraxacum are parthenogenetic and at the same time highly variable they have. looked like tempting material for the study of certain phases of genetics. Moreover their "polysnorphy," as well as that of other parthenogenetic plants, has served as a partial basis for well-known attempts to explain parthenogenesis as due to hybridization.

Poetic Origins And The Ballad, Louise Pound Jan 1921

Poetic Origins And The Ballad, Louise Pound

Department of English: Faculty Publications

The leading theses of the present volume are that the following assumptions which have long dominated our thought upon the subject of poetic origins and the ballads should be given up, or at least should be seriously qualified; namely, belief in the "communal" authorship and ownership of primitive poetry; disbelief in the primitive artist; reference to the ballad as the earliest and most universal poetic form; belief in the origin of narrative songs in the dance, especially definition of the English and Scottish traditional ballad type as of dance origin; belief in the emergence of traditional ballads from the illiterate, …

An Experimental Study Of The Cathode Fall In Helium And Argon With Wire Cathodes, L. G. Raub Jan 1921

An Experimental Study Of The Cathode Fall In Helium And Argon With Wire Cathodes, L. G. Raub

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

It was recognized rather early in the study of the phenomena of discharge of electricity through gases that the ordinary laws of conduction as found in solid and liquid conductors are not applicable to gases. It was shown by Zeleny and independently by Child that Ohm's law by no means represents the distribution of potential between electrodes in an ionized gas, but that the potential gradient is large in the vicinity of the electrodes, and not uniform throughout the space between them. When the pressure of the gas surrounding the electrodes is reduced to one or two millimeters and a …
