United States Patent: Antenna Guy Fitting, Robert Katz
United States Patent: Antenna Guy Fitting, Robert Katz
Robert Katz Publications
The invention to be hereinafter described relates to coupling devices for the attaching of fixed wire antenna to aircraft.
Heretofore, it has been the general practice to make connections between the fixed wire antenna and aircraft by wrapping the antenna wire about a thimble or like device, as in making a splice.
This practice resulted in a number of sharp points and rough surfaces whose susceptibility to corona discharge is well known. This corona discharge resulted in bad weather extremely difficult or dangerous due to interruption of radio navigation and communication services.
The present invention is designed to overcome the …
Application Of X-Ray Technique To The Detection Of Internal Insect Infestation Of Grain, Max Milner, Milford R. Lee, Robert Katz
Application Of X-Ray Technique To The Detection Of Internal Insect Infestation Of Grain, Max Milner, Milford R. Lee, Robert Katz
Robert Katz Publications
During the course of a comprehensive investigation of methods for the determination of internal insect infestation in commercial wheat, radiographic techniques have been developed at this station which provide satisfactory delineation of internal infestation. We have applied these techniques to the observation of the growth of such insects as granary weevil, Sitophilus granaries L., and rice weevil, Sitophilus oryza L., from the hatching of the egg within the kernel through larval and pupal growth to emergence as a mature insect. Although considerable detail is always lost in the reproduction of radiographs during engraving and printing, the accompanying figures (1, …
The Geology Of The Eastern Half Of The Lake City Quadrangle, Anderson And Campbell Counties, Tennessee, Joseph B. Cathey Jr.
The Geology Of The Eastern Half Of The Lake City Quadrangle, Anderson And Campbell Counties, Tennessee, Joseph B. Cathey Jr.
Masters Theses
Preface:
The field work involved in the preparation of this thesis was begun in the fall of 1949 and completed during the summer of 1950. The writer used the geological folio of the area (Keith, 1897) to orient himself in general in the field. The geologic mapping was started in the eastern part of the quadrangle in the Valley and Ridge portion of the area and then continued westward into the Plateau portions. The final study resulted in both stratigraphic and structural modification of some of Keith's interpretations.
The writer gratefully acknowledges the counsel and assistance of Dr. Harry J. …

Nebraska Tractor Tests
All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary. All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University. Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …
The Kinetics Of The Exchange Between Sn(Ii) And Sn(Iv) In Absolute Alcohol, E. Gerald Meyer
The Kinetics Of The Exchange Between Sn(Ii) And Sn(Iv) In Absolute Alcohol, E. Gerald Meyer
Chemistry and Chemical Biology ETDs
In the present work use was made of the radiochemical exchange reaction to study the kinetics of the reaction
SnCl2 + Sn*Cl4 = Sn*Cl2 + SnCl4
in an absolute alcohol medium. A rate equation was established as a function of concentration and temperature, and some predictions were made regarding the mechanism.
A Simple Experiment On Heat, Robert Katz
A Simple Experiment On Heat, Robert Katz
Robert Katz Publications
This experiment requires apparatus consisting of two ring stands, two bunsen burners, safety matches, a sheet of hard asbestos board and a sheet of aluminum of approximately the same dimensions (6 in. long by 3½ in. wide by ⅛ in. thick). The ring stands are set side-by-side with the sheet of aluminum on one and the sheet of asbestos on the other. Two matches are placed on each sheet; one in the middle directly above the bunsen burner and one on the edge, two or three inches away. In what order will the matches catch fire after the burners are …

Some Reactions Of 4-Chlorocinnoline, F. H. Kruse
Chemistry and Chemical Biology ETDs
This problem involves the preparation of 4-chlorocinnoline by the method of Borshe and Herbert and Busch and Rast,, and the study of further replacement reactions of the chlorine atom in the 4-position. The problem can be subdivided into two sections: (1) the preparation of the 4-cinnolyl Grignard reagent and the corresponding lithium compound and (2) the study of some condensation reactions of 4-chlorocinnoline.

Effect Of Stubble Mulching On Number And Activity Of Earthworms, S. P. Teotia, F. L. Duley, T. M. Mccalla
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
A survey of earthworm population under different cropping systems was made under stubble mulch farming and where the residue was plowed under. The influence of earthworms on some of the important physical and biological properties of the soil was studied. Their role in the decomposition of crop residues was also determined.
An Analytical Study Of Berberine, W. Riley Mcgaughran
An Analytical Study Of Berberine, W. Riley Mcgaughran
Chemistry and Chemical Biology ETDs
Berberine, an alkaloid, has unique pharmacological properties as well as unusual chemical and physical characteristics. This compound has been used for many years as a remedy for eye diseases. In contrast to most alkaloids, berberine hydroxide is more soluble than its salts. Its chemical structure has been established, but a correlations of many of its properties and its structures has not been made.
The purpose of this work was to undertake an analytical study of berberine, hoping to collect data which would make possible the correlation of certain properties of the compound with its structure. The study was planned to …
The Effect Of Metals On Yeast Activity, Warren Joseph Chamberlain
The Effect Of Metals On Yeast Activity, Warren Joseph Chamberlain
Bachelors’ Theses
The writer, having been employed in the dry yeast research laboratory of one of this country's largest yeast concerns for the past three years, is very much interested in those factors which might affect the qualities of the final dry yeast product, and has therefore made the investigations presented in this paper.
Because of the numerous pieces of metallic equipment employed in the production of yeast, the possibility of metallic contamination in the final yeast product is considerable. Thus, the investigation presented in this paper was carried out in an effort to determine just what effect various concentrations of various …

The Pleistocene Geology Of The Middle ·Portion Of The Elkhorn River Valley, W. D. Frankforter
The Pleistocene Geology Of The Middle ·Portion Of The Elkhorn River Valley, W. D. Frankforter
Papers from the University Studies series (University of Nebraska)
The present report is a physiographic and paleontologic approach to the Pleistocene history of a portion of the Elkhorn River Valley in parts of Dodge, Cuming and Stanton counties in northeastern Nebraska. The area is important for correlation of deposits between the glacial and periglacial regions. Some of the critical stratigraphic units used for correlation in the Pleistocene of these regions are present in close association with the tills and contain fossils which make possible reliable statements on contemporaneity of deposits. The subsequent geologic history and present physiographic expression of this area have been greatly controlled and influenced by the …
