The purpose of this work was to design a system for measuring
the velocity of a powder actuated fastener or drivepin during penetration.
This system would provide a tool for further investigation
into drivepin penetration characteristics. The main characteristic
of interest is the instantaneous acceleration from which the forces
on...
Achlys triphylla, a member of a medicinally active family
containing alkaloids, was examined phytochemically to determine its
possible value as a source of medicinal agents.
Pharmacological testing of the crude ethanol extract exhibited
a competitive inhibition of acetylcholine and histamine. Purification
of alkaloid 'A' from the crude ethanol extract and...
Routine studies of bacterial fatty acid and lipid composition,
made possible by recently developed techniques, have brought about
an increasing interest in the physiological significance of these
compounds. The purpose of this study was to characterize the fatty
acids of the vegetative cells of Clostridium botulinum 33A, as the
first...
The difficulties encountered in working with micro-quantities
of lipids have been overcome by the advent of new and improved
procedures in chromatography which have made possible better
fractionation and identification. Bacterial lipids because of their
different lipid pattern from other life forms have stimulated much
interest. Studies have been made...
Recent emphasis on range improvement of sagebrush-bunch-grass
types in Oregon has underscored the need for better understanding
of their importance to deer winter range management. The
objectives of this study were to evaluate the impact of various sagebrush
control practices on the composition, production, and utilization
of deer forage plants...
