A Study Of The Physiology Of Grape Roots And Stocks In Relation To A Lime-Induced Chlorosis, Eldrow Reeve

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The word chlorosis comes from the Greek "chloros" meaning light green and is used by plant science workers to designate a disease of plants, the characteristic symptom of which is the yellowing of the leaves.

A Celestial Globe, John D. Boon

Field and Laboratory

Nature is deceptive. Things that appear to be true are often untrue. This point is well illustrated in the science of astronomy. The history of astronomy is strewn with rejected theories that were once held by wise men. Even today many false theories that should have been discarded long ago are believed by many people. Why is this true?

Bulletin No. 295 - Comparison Of Two Methods Of Determining Wool Density, Milton A. Madsen, Ralph W. Phillips, John V. Christensen, Roy L. Henrie

UAES Bulletins

Density of the fleece is one of the primary factors determining the wool-producing capacity of the sheep. Sheepmen have attempted to evaluate density by handling the fleece. This method is not sufficiently refined for use in experimental work, and may be subject to errors and misinterpretations. For example, if two fleeces are alike in density and diameter of fibers, yet differ in length, the longer fleece will feel less dense. If, on this basis, the sheep with the fleece that appeared most dense were selected for breeding, selection would be away from the longer fleece. Any method that can be …

Wildlife Of The Atlantic Coast Salt Marshes, W. L. Mcatee

United States Fish and Wildlife Service: Publications

Salt marshes of the Atlantic coast have been formed under the opposed tendencies of sinking of the land and of its upbuilding by silt and sand. The plants that form the marshes occupy zones largely determined by the degree of inundation by tides. Eelgrass entirely submerged, smooth cordgrass regularly washed by the tide, and marsh hay covered only by exceptionally high water are characteristic plants. Each zone is the home or feeding area of certain kinds of wildlife. The appearance, distribution, and habits of the more common species are described, and general wildlife conservation is urged. This circular, which is …

Bulletin No. 294 - Research Aids Utah Agriculture: Biennial Report Utah Agriculture Experiment Station 1938 - 1940, R. H. Walker

UAES Bulletins

The foundation of progress in agriculture as in any other industry is research. Research has resulted in knowledge now daily applied in soil treatment, in irrigation practices, in dealing with insect pests, in breeding new varieties of plants, in animal improvement, in better farm practices, and in better land-use planning. Research undertaken by the Utah Agricultural Experiment Station has been outlined to solve specific problems facing Utah agriculture, among them the problems of irrigation, dry farming, range management and animal production. The prosperity of the state is dependent upon the success of these agricultural enterprises. Agricultural research should not, therefore, …

A Study Of The Geographical And Ecological Distribution Of The Buffy Plains Pocket Mouse (Perognathus Flavescens Flavescens), With Description Of A New Subspecies From Nebraska, Myron H. Swenk

University of Nebraska State Museum: Mammalogy Papers

The Buffy Plains Pocket-mouse (Perognathus flavescens flavescens) is a typical mammal of the Sandhill Region of Nebraska. Its home, like that of other species of pocket-mice, is a series of burrows in the ground, consisting of several entrance holes leading to the main 'burrow, in which is located the nest and the food storage chambers. In the Nebraska sandhills its burrows and nests are commonly placed beneath clumps of Spanish Bayonet or Prickly Pear Cactus, and the entrance holes usually are so distributed as to open from under the plant in all directions.

The writer had hoped to …

The Effects Of An Insufficient Carbohydrate Diet On The Leucocytes Of The Normal Albino Rat, Carl Frederick Glienke

Bachelors’ Theses

This thesis deals with the effects of an insufficient carbohydrate diet on the differential counts of the leucocytes of the common albino rat. The experiment was chosen because of the interesting problem it presented and because little could be found on work done regarding it. To the ’writer’s knowledge, very little work has been done in even establishing a definite differential count of a normal rat, much less working on one under an abnormal condition. Because of this lack of information, a normal count was first established for the strain used, and then this count was compared with that of …

Resistance To Staphylococcus Aureus In White Rats, Robina B. Langill

Bachelors’ Theses

An investigation of bibliographies shows that staphylococcus aureus in its pathogenic potentialities has been extensively investigated from varied points of view and with frequently conflicting results.

Staphylococcus aureus is most frequently associated with furuncles, wound infection, and minor skin abcesses. Occasionally, however, due to extreme lowered resistance or other conditions not fully understood, staphylococcus causes a septicaemia which is attended by an 80% mortality rate. Post-mortem examinations of the victims of such septicaemia show an extensive invasion of all organs of the body by the bacteria but more particularly a hyperplasia of the lymph nodes, the spleen and thymus, indicating …

Comparison Of Various Types Of Milk Sampling Devices, William A. Hoskisson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of an accurate measurement of fat in milk deliveries is fully appreciated by most producers and plant operators. Since milk is purchased on a fat basis, the accuracy of the procedure used in sampling and testing the milk has often been questioned by both the buyer and seller.

A composite sample to be theoretically correct, should consist of aliquot portions of the milk shipments represented. Where aliquot portions are to be taken, a milk thief is commonly suggested. This device takes a vertical column of milk from the weigh tank. The idea is that the height of the …

Vegetative Composition And Grazing Capacity Of A Typical Area Of Nebraska Sandhill Range Land, A. L. Frolik, W. O. Shepherd

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The sandhill area of Nebraska occupies approximately 20,000 square miles of the central portion of the state. Being unadapted to cultivation, the land is for the most part still covered with native vegetation. It is utilized primarily for the production of livestock, chiefly cattle. During the period 1931 to 1938 the sandhills carried annually an average of 1,041,000 cattle, which amounted to 31 per cent of the total number in the state. The management practices used in the Nebraska sandhills have gained national recognition as a good example of range conservation in the United States. The purpose of this study …

A Study Of Subspecific Variation In The Yellow Pocket-Gopher (Geomys Lutescens) In Nebraska, And Of The Geographical And Ecological Distribution Of The Variants, Myron H. Swenk

University of Nebraska State Museum: Mammalogy Papers

The Yellow Pocket-Gopher (Geomys lutescens) was described by Merriam (14) in 1890, as a paler and smaller subspecies of Geomys bursarius, based on "numerous specimens received from the Sand Hills of western Nebraska", and especially upon an adult Cjl type specimen (No. 23595, U. S. N. M.) collected in the sandhills along Birdwood Creek, Lincoln County, Nebraska, May 27, 1889, by A. B. Baker. Although even as late as 1931 Scheffer (17) classified Geomys lutescens as a subspecies of G. bursarius, it is without doubt specifically distinct from G. bursarius. In all of its variations …

An investigation of bibliographies shows that the red corpuscles of the blood have been studied very extensively, in fact, wore so than any cell in the mammalian body. The study has progressed vigorously and from varied points of view.

Staining Techniques In The Study Of The Blood, Donald E. Winnik

Bachelors’ Theses

Since the invention of the microscope, the study of the blood and its constituents has been a major interests of histologists and hematologists. The vast amount of material written about the subject could not have been accomplished without the development and use of staining techniques which made possible a more precise observation of the nature of the blood. At the present time there are many procedures and stains which vary greatly in their application and use. It is the purpose of this thesis to review these many methods and catalogue them according to their application in the blood techniques.

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 …
