A New Grain Hardness Tester, Robert Katz, A. B. Cardwell, N. D. Collins, A. D. Hostetter
A New Grain Hardness Tester, Robert Katz, A. B. Cardwell, N. D. Collins, A. D. Hostetter
Robert Katz Publications
A hardness tester, especially adapted for grain, was constructed by modifying a commercial portable soft metal tester known as the Barcol Impressor. A preloaded stylus is forced into grain sections prepared by means of a microtome. The displacement of the stylus, measured by a dial micrometer, is used as a hardness index. This has been related to the Vickers diamond pyramid hardness which is a standard metallurgical test. A number of hardness measurements may be made on a single transverse kernel section. The tester may be used for all wheat varieties. Significant variations in hardness within a single wheat kernel …

Production Of Waterfowl In The Rain Basin Area Of South Central Nebraska, Ray Linder
Production Of Waterfowl In The Rain Basin Area Of South Central Nebraska, Ray Linder
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
One important form of wetlands habitat in Nebraska is the “Fresh-water Basins”; their importance extends to both waterfowl and upland game. The fresh-water basins are located primarily in south-central Nebraska. They are closed drainages, usually from one to 40 acres but ranging up to 1,000 acres, formed in the gently rolling loess plains. Soils are silt loam and the somewhat impervious soils in flat or depressed position receive and retain the largest amounts of water. This caused leaching and concentration of clay in the subsoil forming a soil type peculiar to these areas known as "Scott silt-loam," a heavy clay-loam …

Four Dimensional Graphs Of Complex Functions, Malcom Lee Murrill
Four Dimensional Graphs Of Complex Functions, Malcom Lee Murrill
Master's Theses
Complex functions of a single complex variable involve four unknowns, two independent and two dependent variables, and thus cannot be adequately represented in two- or three- dimensional space. Various geometric constructions in both two and three dimensions have been devised in the past, however, in attempts to illuminate complex function theory. The standard and most useful, of these representations is that developed by Gauss and Riemann employing two complex planes simultanesously. These show the correspondence between a particular curve or region in the object plane and its image, as mapped by a given transformation, in the image plane.
Studies On The Biological Oxidation Of Ferrous Iron And Chalcopyrite, Loral Alvin Decker
Studies On The Biological Oxidation Of Ferrous Iron And Chalcopyrite, Loral Alvin Decker
Theses and Dissertations
The purpose of this investigation was to determine the effectiveness of the leaching streams from waste copper ore dumps as a nutrient solution for subsequent biological oxidation and solubilization of sulfide minerals. The copper in the leaching streams is precipitated by displacement with iron. As a result of this procedure the solution is high in ferrous iron concentration and has a pH of near 3.7. The bacteria in the leaching streams are capable of oxidizing ferrous iron to the ferric state and sulfide minerals to sulfates. The effects of temperatures, pH, urea, and aeration rate on the oxidation of the …
The Cytochrome Composition Of Bacillus Subtilis And Bacillus Megaterium, John Harvey Mangum
The Cytochrome Composition Of Bacillus Subtilis And Bacillus Megaterium, John Harvey Mangum
Theses and Dissertations
A spectroscopic and enzymatic investigation of the cytochromes of B. megaterium and B. subtilis was conducted. Attempts were made to isolate and characterize the individual cytochromes as well as to determine the locale of such activities as cytochrome c oxidase, DPNH oxidase, succinic dehydrogenase, cytochrome c reductase and diaphorse. Only two methods proved effective in liberating the cytochromes; disruption of the cells with sonic osillations and grinding tlhe cells with alumina. These procedures caused a fragmentation of the cell membrane. It was found that the entire cytochrome complement of these two bacteria was bound intimately to particles which most likely …

Substituted Triphenyl Tetrazolium Chlorides, Lawrence Donald Hanback
Substituted Triphenyl Tetrazolium Chlorides, Lawrence Donald Hanback
Master's Theses
The work in this thesis is a continuation of a project started at the University of Richmond in 1952 by A. G. Richardson under the directorship of Dr. J. S. Pierce and Dr. George z.Williams, Director of Clinical Pathology, National Institutes of Health, Bethesda, Maryland.
The purpose of the research was to prepare triphenyl tetrazolium salts, substituted, particularly in the ortho and para positions, with various electron accepting and electron donating groups. It was hoped that these substitutions would impart enough differences in the properties of the compounds so as to allow d etection of certain biological reactions. The tetrazolium …
