Environmental mycobacteria are important opportunistic pathogens for many hosts,
including humans, cattle, and fish. Two well-studied species are Mycobacterium
avium subsp. avium, a significant cause of disseminated bacterial disease in patients
with AIDS, and Mycobacterium avium subsp. paratuberculosis, the cause of Johne’s
disease in cattle. Many other species that are...
Metal-insulator-metal (MIM) and dual-insulator MIM (MIIM) devices are used in rectennas, hot-electron transistors, single electron transistors, resistive random access memory (RRAM), and capacitors. The performance of these devices relies heavily on the energy barrier height at each metal-insulator interface. Thus, determination of the in-situ electron energy barrier at each interface...
The purpose of this study of the life and career of Dr. Carl
Leonard Anderson was to recount his professional contributions to
the field of health and relate these to public health and health education. The major emphasis of this study concerned Dr. Anderson's
professional life.

Phytoplankton dynamics in Auke Bay, Alaska, were studied during
summer, 1969. Nitrate, chlorophyll a, particulate organic carbon,
phytoplankton and zooplankton species composition and hydrographic
and meteorological data were collected and analyzed.
Nitrate input into Auke Bay through freshwater runoff was negligible.
A bloom of Thalassiosira aestivalis formed the spring bloom...
L. C. Dunn (1893-1974) spent most of his scientific career conducting research in
developmental genetics as a member of the Zoology Department at Columbia
University in the City of New York. He had an accomplished scientific career
researching mutations in mice, which earned him respect from other geneticists and
scientists....
This thesis describes investigations of marine algal secondary metabolites, with particular interest in their biomedical and agrichemical potential. Invaluable in such pursuits have been the access and application of advanced spectroscopic techniques, such as NMR, and the ability to assess the biological activity of the algal samples in a variety...
This thesis is an account of my explorations into the field of natural products chemistry. These investigations led to the discovery of several novel secondary metabolites isolated from the marine cyanobacterium Lyngbya majuscula. In addition, biosynthetic investigations were undertaken using stable isotope-labeled precursors. The dominant role that NMR spectroscopy plays...
