Clatsop Beaches, characterized by flat beach-face slope (1:70) and small sandsize (0.2 mm.), have supported commercial and recreational fisheries for the razor clam (Siliqua patula) for many years. Tracing the linear growth of two year classes through more than one year following set led to a validation of the ring...
The preparation of 4-(3-hydroxypropyl) cyclohexanone and
of 4-(3-hydroxypropyl) cyclohexene and a number of their derivatives
as potential precursors of asymmetrically substituted bicyclo [3, 3, 1]
nonanes is described.
The ketone, 4-(3-hydroxypropyl) cyclohexanone, was prepared
from p-allylanisole by three different routes. Common to each
route was an initial hydroboration-oxidation followed by...
The use of radioactive isotopes as tracers in biological systems
has become widespread since the close of World War II. Proper
use of radiotracers requires a fundamental understanding of the physical
nature of radioactivity, the characteristics of ionizing radiation,
and the various methods available for measuring radioactivity.
More importantly, the...
