Test 664: Allis-Chalmers Hd-21a (Diesel), Nebraska Tractor Test Lab

Nebraska Tractor Tests

This report and any related files are made available to the online through the Lester F. Larsen Tractor Test and Power Museum as resources allow. Established in 1998, this museum is located on the University of Nebraska-Lincoln East Campus. It is and appropriately housed within the walls of the historic 1920 Nebraska Tractor Test Laboratory, where the first tractor test was started on March 31st, 1920. Because the pioneer tests became worldwide standards, this location was designated as a Historic Landmark of Agricultural Engineering by the American Society of Agricultural Engineers in 1980, shortly after testing was moved to a …

Thermodynamic Properties Of The System Pucl3-Kcl, Robert Benz

Chemistry and Chemical Biology ETDs

It is a general experimental result that as the temperature of a chemical system is increased the thermodynamic parameters of state become more important while the diffusion controlled and other activation type parameters become less important in controlling the net chemical reaction. The growing intereats in chemical processing of plutonium materials at elevated temperatures has emphasied the importance of an accurate knowledge of the thermodynamic data tor plutonium compounds as an aid to the prediction and the study of possible economically feasible processes.

Spectrophotometric Study Of The Boron- Curcumin System, Frank Xavier Pollio

Master's Theses

In the present research project an attempt has been made to determine the mechanism of the reaction followed in the curcumin spectrophotometric method for boron determination using a modification of Naf'tel's method.

Spectrophotometric Study Of The Boron-Curcumin System, Frank Xavier Polio

Master's Theses

With mechanism and structure in mind, the aim of this research project was to investigate the role played by the various reagents used in the curcumin spectrophotometric method. The reagents were used in varied concentrations and at times some eliminated entirely, in the hope that a greater understanding be gained in the overall mechanism followed by the reaction.

One of the major objectives was to try to determine the structure of the colored substance formed in the reaction. A step towards this goal was gained by obtaining molar ratios of the entities suspected to be an intricate part of the …

Decahydroquinoxaline : Stereoisomers And Derivatives, Lynn Pendleton

Theses and Dissertations

The preparation of decahydroquinoxaline by four different methods, with no determination of geometrical configuration made, was reported in the literature. The purpose of this thesis was to establish the geometrical configurations of the decahydroquinoxalines prepared by these four methods and to determine if, as the work of previous investigators suggested, the two pure isomers of decahydroquinoxaline isomerized, each giving an equilibrium mixture of both isomers. Decahydroquinoxaline was prepared by three of the four previously reported methods of preparation. Comparison of the properties of the decahydroquinoxalines prepared and the preparation, comparison, and analyses of the diacetyl and the dinitroso derivatives of …

Rhenium Trioxide, Rhenium Heptoxide And Rehnium Trichloride As Hydrogenation Catalysts, William J. Bartley

Theses and Dissertations

The purpose of this study was to characterize the catalytic activity of rhenium trioxide and rhenium trichloride as hydrogenation catalysts. Work was also undertaken to further study the catalytic properties of rhenium heptoxide. The activity of this latter compound had received some study in a previous project. A complete review of the literature has been made on the organic and inorganic chemistry of rhenium trioxide and rhenium trichloride. A survey of the literature on catalytic hydrogenation and the chemistry of rhenium heptoxide has also been included. Rhenium trioxide was prepared by three similar methods. The first two involved the formation …

Synthesis Of 4, 7-Disubstituted Derivatives Of Imidazo-[4, 5-D]-Pyridazine And Related Compounds, William Seese

Chemistry and Chemical Biology ETDs

The antitumor activity of 8-azaguanine (5-amino-7-hydroxy-v-triasolo([d] pyrimidine) (A) prompted the preparation of the imidazo-[4, 5-d] pyridazine ring system (B). In this ring the two nitrogen atoms are adjacent in the six-membered ring with the five-membered imidazole ring remaining the same as in the parent purine ring (C).

Some Aspects Of The Non-Aqueous Chemistry Of The Uranium Chlorides, Richard E. Panzer

Chemistry and Chemical Biology ETDs

Uranium, discovered by Klaproth in 1789, has been the object of greatly intensified chemical and physical studies since the establishment of the Manhattan Project. An event such as the discovery of the hexachloride of uranium in 1943 points up the relatively unknown status of the chemistry of this element at a fairly recent date. It is not, therefore, surprising that the chemistry of many compounds of greater complexity than the hexachloride had not been investigated. However, with the search intensified for methods of separation of the naturally occurring isotopes for subsequent use in nuclear weapons and reactors, the years since …
