The Reaction Of N, N-Disubstituted Ketohydrazones With Lead Tetraacetate, Elisabeth Cerda

Masters Theses

Introduction

The reaction of lead tetraacetate with compounds of the following general structure (not able to enter here) was first reported by Iffland and Criner (12). In the case of ketoximes (A = oxygern), a nitrosoacetate was produced which was oxidized to the more stable acetoxy-nitrocompound as follows: (not able to enter here)

The generality of the reaction was established by preparation of a series of acetoxy-nitrocompounds from alicyclic and aliphatic ketoximes. The apparently similar reaction of cyclohexanonephenylhydrazone (A = N-¢) with lead tetraacetate was reported, but the reaction product was not identified.

Temperature Distribution In An Infinite Plate As A Function Of The Input Heat Flux, George Franklin Wright

Masters Theses

"It is the purpose of this thesis to investigate the effects of a variable input heat flux impinging equally on both sides, on the temperature distribution within an infinite plate. An infinite plate may be defined as one in which the dimensions are infinite in two directions and finite in thickness. For practical purposes such a plate could be thought of as one in which the thickness was small enough, compared to the other two dimensions, so that a temperature gradient exists only normal to the surfaces of the plate. This assumption will be made to establish one-dimensional heat flow …

Transient Temperature Distribution In Solid Sphere Subjected To Radiation Heat Exchange, William H. Stocklin

Masters Theses

"The author believes that numerical analysis is the most feasible approach to calculating the transient temperature distribution in a solid sphere subjected to various surface conditions; heat flow within the sphere is radial.

Numerical analysis is employed to arrive at a series of equations for calculating the transient temperature at selected points of a solid sphere. A study is made to determine a method for calculating temperatures with these equations; a computing device is found to be the most practical method for this purpose. The equations for temperatures at internal points of the solid sphere are general.

A Study Of The Energy Dissipation And The Related Pressures And Velocities Of Cylindrical Tank Type Stilling Basin, Graham Wayne Wood

Masters Theses

"In all hydraulic structures that hold back water, whether for the purpose of power, irrigation or flood control, all must have some means of dissipating the energy that is produced by the movement of the water from the pond or reservoir to the tailrace. The method of dissipation depends largely on downstream conditions, terrain and economics. The dissipator is to prevent scour and the undermining of the dam itself. The construction of any type dissipator should be the best one available for the least cost of construction. However, space limitations may dictate another type of dissipator. It has been recommended …

Certain Features Of Alteration In The Michigan Lavas And Their Genetic Interpretation, Peethambaram Doraibabu

Masters Theses

Effects Of Solids On Friction Factor In A Sand-Water Mixture, Frank J. Capek

Masters Theses

"At the present time various industries in both the United States and Europe are very interested in using pipelines as a means of transporting solids. The pumping of solids in pipelines isn't new, however, many of the pipelines in use today were constructed on an empirical basis. This is primarily due to the lack of knowledge concerning the flow properties in fluid-solid mixtures and slurries. With this need for fundamental information in mind, the author made a study on the effect solids have on the friction factor in fluid-solid mixtures.

In this paper various percentages of fine and coarse sand …
