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...
Sisson's formally exact series solution for momentum, heat and
mass transfer in steady two-dimensional or axi-symmetrical constant-property,
laminar boundary layer flow was examined. A new series
was proposed for the boundary condition accounting for the mass
transfer at the surface of the body on which the boundary layer is
formed....
The purpose of this study has been to develop
insight into the aims and goals of public library service by
considering one particular type of library activity--work
with adult groups.
To determine the influence of historical events on
such service, consideration has been given to group work of
