This thesis studies the effects of certain organic compounds upon the bacterial deposition of ferric hydroxide from ferric ammonium citrate.

This thesis is a spectrographic study of a select group of actinomycetes.

The purpose of this study is to determine the relationship of light wave length to tissue differentiation in sunflower seedlings.

This investigation was planned to observe if the leukemic thymic tissue in vitro would inactivate TSH and to study the effect that TSH would have on the leukemogenic properties of these cells when transplanted into a high-leukemia strain of mice.

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.
