Delayed neutron counting (DNC) is a variation of neutron activation analysis applicable only to fissionable elements. Briefly, it
involves exposing a sample to the neutron flux in a reactor to induce
fission, then quickly retrieving the sample to count the delayed
fission neutrons emitted. These are proportional to the amount...
Adventitious root formation can be inhibited in stem cuttings
of Pisum sativum L. (pea), an easy-to-root species, if the apical
and lateral buds are removed. Application of exogenous auxin to
the apical stump can replace the rooting stimulus produced by the
buds. Root number was reduced by 50 to 100%...
Jeffrey pine occurs in the mountains of California and adjacent states. In the Klamath Mountains, the northern margin of the range, it is restricted to infertile ultramafic soils, forming very open stands of low density. It occurs predominantly on more fertile soils in the Sierra Nevada and southern portions of...
This thesis describes the results of a project conducted to determine the economics of forest road maintenance alternatives
between periods of timber harvesting. An open road and a closed road alternative will be compared to the economics of clearcutting an
entire area and obliterating the road system until reentry at...
