A conceptual model of the tidal flat system, emphasizing the
sulfur cycle was presented. Measurements were made of the vertical
distribution within tidal flat deposits of total aerobic and sulfate
reducing bacteria, total sulfides, redox potential, volatile solids,
and particle size. Variations in dissolved oxygen and free sulfides
in the...

An examination of the technical and historical literature
concerning the discovery and development of antibiotics suggests the
possible existence of an era of discovery. This era appears to have
a well-defined beginning (about 1940) and a well-defined close (about
1960). It is the purpose of this dissertation to examine the...
The study was conducted to identify variables, from
among the theory related and demographic/biographic variables
included in the study, which were able to discriminate
between groups of male and groups of female freshmen
who differed in their level of self-actualization.
Five hundred and forty freshmen (277 males and 263
females)...
