Segregation, as in other realms of American life, is a great problem of the churches. Although the Supreme Court decision and call for action by the President have produced few revolutionary changes, the churches of the South have taken steps to cope with this problem.

The purpose of this study is to measure and compare the degree of personal and social adjustment which high school girls exhibited during a "split semester" and a "continuous semester."

A radio-frequency positive-ion source and a fifty-kilovolt linear accelerator were designed and constructed in order to produce sizable quantities of hydrogen, helium, nitrogen, neon, and argon. Plans were then made to equip this ion source with charge-exchange apparatus suitable for charge-exchange cross-sectional measurements. It is the purpose of this paper to present the design of the equipment and to present operational knowledge of the equipment and of ion beams which are producible.

The specific goal of the investigation was the measurement, as a function of temperature, of the self-diffusion coefficients of Pb210 and Cl36 in PbCl2-KCl compositions in the region of the first compound, and to calculate from these data the activation energy necessary for the diffusion of these ions.

This thesis is a study of the Confederate command problem in the Trans-Mississippi West, 1861-1862.
