Some Aspects Of Printing Quality, Robert B. Badger Jr.

Paper Engineering Senior Theses

The object of this experiment was to find the effect of various pressures upon the ink coverage and the visual appearance of the half-tone print. A specially designed plate with four evenly spaced elevations was used with a Vandercook proof press. Various grades of paper were used. Results showed: a variation in the range of ink coverage due to the grade of paper and the number of lines of the half-tone; within the area of good printing a small change in pressure caused a large change in ink coverage; the change in ink coverage varied from elevation to elevation; an …

An Iron Fulgurite From Nebraska, C. M. Riley

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

From the time of the ancients man has been impressed with the force of lightning and its effect on the rocks at the surface of the earth. It was Saussure in 1786 who first wrote a scientific account of a true fulgurite, and a wealth of literature has been written about the subject since this time. Many unusual fulgurites have been described, some of which may not truly be the result of lightning. The iron fulgurite is a strange conical object about 3 inches high composed mainly of tiny spheres and filaments of metallic iron intermixed with a small amount …

Men Of Science In Texas, 1820-1880, S. W. Geiser

Field and Laboratory

Recently there came back into my hands a lent-and forgotten-dossier of 1929 correspondence with Swiss and German universities and libraries-a correspondence dealing with the Swiss naturalist, Jacob Boll, who spent the last years of his life in Texas. His life, with that of other naturalists, is sketched in my Naturalists of the Frontier (1937, 1948). Such a recovery reminds one of the passing of time, and a long-made promise to put into print an account of the men of science (sit venia verbo) of Early Texas. Most of them were men of other trades, professions, what-you-will, of good amateur standing; …

A Study Of Three Photochemical Activities Of Chloroplasts, Jimmy W. Hinkson

Theses and Dissertations

Chloroplasts of sugar beet leaves were subjected to treatment by heating, by incubation at pH 8.5 and pH 5.5, by incubation in ion low water, by sonic oscillation, by digestion with enzymes (lysozyme, pancreatin, and lipase), by extraction with digitonin, and by chemical compounds including 8-hydroxy-quinoline, sodium azide, zinc sulfate, phenyl mercuric acetate, potassium cyanide, 1-allylthiourea, 2,4-dinitrophenol, thymol, and p-chloromercuribenzoate. A comparative study was made of the effects of these treatments upon three photochemical reactions (the photoreduction of 2,6- dichlorophenol indophenol, the photoreduction of indigo carmine in the presence of a couple composed of 2,6-dichlorophenol indophenol and ascorbic acid, and …

4. Social Darwinism, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XV: Biology and the Rise of the Social Sciences

The singular impact of Darwin in fields other than biology can be attributed largely to one man, Herbert Spencer (1820- 1903). It was Spencer, not Darwin, who coined the expression "survival of the fittest." Although neglected today except by historians of the nineteenth century thought, Spencer's influence on his own time was so great that Justice Oliver Wendell Holmes was able to wonder if "any writer of English except Darwin has done so much to affect our whole way of thinking about the universe." Herbert Spencer was born into a traditionally nonconformist English family of modest means. He refused a …

1. Charles Darwin And Organic Evolution, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XV: Biology and the Rise of the Social Sciences

Evolution was not a new idea. The Greeks speculated on it. In the century before Darwin many different evolutionary theories were proposed, among them notable efforts by Buffon, Lamarck, and Goethe. Their common thread was the concept that the succession of biological changes in geological time represented a fact, if not a natural law. The stumbling block was for all of them, as it had been for Cuvier, the concept of fixed species, which clashed with the vision of a distant past populated with races of plants and animals now extinct. It became evident that the idea of fixed species …

Section XIV: The Industrial Revolution, Classical Economics, and Economic Liberalism

While capitalism was making rapid strides toward dominating English industry, changes were taking place in agriculture which made it more efficient and productive, and which prepared it to be fitted eventually into the industrial capitalistic pattern. Actually, changes in the direction had been occurring in English agriculture since the revival of trade discussed in earlier chapters. [excerpt]

Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson

Nebraska Game and Parks Commission: Publications

The purpose of this booklet is to provide a ready field reference for identification, sexing and aging of common game species. It has purposely been kept in simplified form, presenting only those techniques which can commonly be applied in the field and avoiding those which would require special equipment and skills. Untrained personnel should be given demonstrations of the techniques, and thereafter this reference should serve as a reminder. It is not expected that the reference could successfully be used without such demonstration. Certain of the techniques such as cloaca! examination of waterfowl may require considerable practice by the individual. …

Gustavus Wilhelm Wuerdemann (1817-59), Early Naturalist Of The U.S. Coast Survey, S. W. Geiser

Field and Laboratory

The recent appearance of Wraight & Roberts' sequicentennial historical account of the U.S. Coast & Geodetic Survey calls to mind the splendid natural-history collections that G. W. Wurdemann, tidal-observer and meteorologist, made during the years 1844 to 1859, especially in Texas, Louisiana, and Florida. As no extended biographical notice of this naturalist has appeared in the nearly one-hundred years that have passed since his death, the present note may be of interest to students of the history of scientific exploration in the early South and Southwest.

Chemosynthetic Microorganisms In Leaching Sulfide Minerals, A. Keith Jameson

Theses and Dissertations

This investigation showed that a single bacterium was capable of sulfide oxidation in exposed ore bodies. This single bacterium was isolated and characterized. It exhibited different characteristics than any previously known organism. It was found to be a chemosynthetic autotroph. An optimum nutrient concentration was determined for pyrite oxidation. The nutrient concentration was determined for pyrite oxidation. The nutrient contains only a source of phosphate and nitrogen. Urea was found to be a better source of nitrogen than ammonium sulfate which had previously been used. The effect of various organic compounds on the oxidation of pyrite was observed. Glucose and …

Combining Field Fertilizer Trials With Soil Tests In An Effort To Obtain The Most Suitable Soil Nitrogen And Phosphorous Tests For Southern Alberta, Einard Haniuk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Under dryland farming operations, the use of fertilizers is often restricted due to limited crop response arising from limited seasonal moisture. Once this dryland area is brought under irrigation, there is increased use of fertilizers and increased demands for greater exactness in amounts of fertilizers to apply, due to efforts which are made to increase the returns from the land by introduction of new farming techniques and crops.

The Use Of Branchiostegal Rays To Determine Age Of Lake Trout Salvelinus Namaycush Walbaum, Ross Vivian Bulkley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Any method used in aging fish must fulfill certain requirements to be satisfactory. If the method is inaccurate, naturally little reliance can be placed upon its use. If considerable study of the method and much practice are required before accurate readings can be obtained, the method will not come into widespread use. The requirements of an aging method, then are that it must be accurate and comparatively easy. The scale method for aging lake trout (Salvelinus namaycush Walbaum) unfortunately does not fulfill these requirements. It has always been difficult to tell the age of lake trout by the examination …

Medial Pleistocene Fossil Vertebrate Localities In Nebraska, C. Bertrand Schultz, Lloyd G. Tanner

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

The accurate geologic dating of Pleistocene vertebrate localities which occur outside the glaciated regions has always been difficult. Several new fossil localities in Nebraska now provide data for a better understanding of the paleoecology and faunal evidence of the medial Pleistocene of the Great Plains region.

A fossil quarry, containing the remains of both vertebrates and invertebrates, has been discovered in south-central Nebraska (11/2 miles south and west of Angus in Nuckolls County). The fossils are preserved in Sappa silts in a lime concentration zone (C horizon) of a Yarmouth paleosol. The calcium carbonate appears to have been responsible for …
