This paper is divided into two parts. The first part
traces (in details providing proofs and examples) the
history of the solutions of polynomial equations(of the
first, second, third, and fourth degree) by radicals from
Babylonian times (2000 B.C.) through 20th century. Also it
is shown that there is no...
Ecologists have studied the responses of pelagic ecosystems
to varying levels of nutrient loading and fish predation on many
different scales ranging from small experimental enclosures to
whole lake systems. There are recurring patterns of response to
these two variables, which are generally predictable on the basis
of biogeographic, behavioral,...
I have participated in a drug discovery program designed to screen marine algae for
inhibitors of cancer-related enzymes, antitumor compounds, antiinflammatory substances,
and other agents of potential pharmaceutical utility. Over 1,500 lipid and aqueous extracts
of marine plants and animals were surveyed for biomedical potential. Assays designed to
screen extracts...
In this thesis anomalous downcore shallowing of paleomagnetic
inclinations is interpreted to be caused by sediment compaction. Thus,
compaction-induced inclination shallowing may influence tectonic
reconstructions that are based on inclinations from deep-sea sediment
cores.
Progressive downcore shallowing of the remanent inclination was
observed in a 120-m section of Plio- Pleistocene...
