ANALYSIS OF THE INTERACTION OF 300-Mev NEUTRONS WITH XENON

Description: An investigation of the interactions between 300-Mev neutrons and xenon was made by means of a cloud chamber in a pulsed magnetic field of 21,700 gauss placed in the neutron beam of the 184-inch Berkeley cyclotron. Eighty-seven negative pion events and 257 other stars were analyzed. In addition an experimental check was made on the energy of the incoming neutrons. Classification, identification, and angular and energy distributions of prongs associated with all events are presented. Interpretations of results are given.

Alpha-Decay Studies in the Heavy-Element Region

Description: Using primarily a 75-cm radius of curvature 60 deg symmetrical electromagnetic analyzer, a study of the complexity of the following alpha spectra was made: Es/sup 253/, Cf/sup 246/, Cm/sup 244/, Am/sup 243/, Pu/sup 236,242/, Pa/sup 231/ , Th/sup 227,230/, Ac/sup 225/, At/sup 209/ and Po/sup 206/. An investigation of the gamma rays associated with the following isotopes was also madei /sup 236/, and Pa/sup 231/. Decay schemes have been suggested for most of the isotopes included in this study. Those for the even-even isotopes were found to conform well with the previously existing systematics for that group of nuclides. Many of the decay features of the odd-mass isotopes seemed to conform well with presently expanding theories. (auth)

Considerations in Selecting, Developing, and Validating Laboratory Experience Units in General Biology for Prospective Elementary School Teachers

Description: The primary purpose of this study was to develop the considerations and techniques for the selection, development, and validation of laboratory experience units in general biology for prospective elementary school teachers. The completed laboratory experience unites developed in this study may serve as resources of activities for college instructors who teach general biology to undergraduate majors in elementary education. For purposes of this study the laboratory experience unites were centered about those principles of general biology which an elementary school teacher should understand in order to teach about plants and animals.

The Validity of the Texas Economic Index

Description: Since the economic index is one of the two instruments which are so important to the financing of every school district of the state, and since the index is a hypothetical measure, it should be studied at regular intervals. Therefore, the purpose of this study is to re-examine the economic index used in Texas school finance for the purpose of determining its validity.

An Investigation of Algae and Common Tastes and Odors in Fresh Water

Description: The purpose of this investigation was to isolate and grow algae common to the southwest in unialgal culture; to either sustain or grow one of the principal bloom-causing organisms, with emphasis on Microcystis aeruginosa; to isolate and culture actinomycetes from the same waters from which the algae were obtained; and to inoculate these algae with actinomycetes and determine their effects through development and deterioration.

An Analysis of the Progress of Unions in Organizing Professional Engineers

Description: The problems of this research report were threefold: 1. To trace the history of the unionization of engineers from its inception to the present time. 2. To present the arguments of those individuals and groups who practice and favor engineering unionization, and to set fort the counter-arguments of those individuals and groups who reject unionization for engineers. 3. To summarize the facts and opinions discovered and, in view of these findings, to draw conclusions on the merits and the trend of engineering unionization.
