Stem mapping of all trees greater than 15 cm dbh has
been completed on the 10.24 hectare watershed (No. 10) at H. J.
Andrews intensive study site. Using a 25 m grid system, mapping
of vegetation into 7 plant communities and then into 4 habitat
types has also been completed....
Calcium concentration and its regulation was examined in
tissues of larval Rana catesbiana. Considerable variability was
found in tissue calcium that could not be explained by stage of development.
A seasonal effect was observed, with plasma calcium decreasing
and muscle calcium increasing during winter. Total plasma
calcium concentration reflects, within...
Investigations of plasma production by a pulsed dye laser
microprobe were made. Comparisons between a Q- switched and a
pulsed dye laser system were made on the intensity of the continuum
produced by atmospheric breakdown. The dye laser system was
foundtominimize the production of the continuum which in turn
allowed...
Studies were conducted with Indian River "Hybro" broiler chicks
and Oregon Agricultural Experiment Station dwarf and normal White
Leghorn hens to improve the utilization of white western wheat. Chick
studies were primarily concerned with characterizing the growth
inducing properties of an antibiotic fermentation residue (Vigofac)
which had shown a greater...
A cost reduction analysis is performed by coordinating
the exchange of LANDSAT (formerly ERTS) data between a CDC
3300 and a PDP8/L minicomputer. The LANDSAT data is displayed
on a 4002 Tektronix terminal by means of a grayscale output.
Large amounts of data and number manipulation are processed
in the...
The energy absorbed by microscopic volumes exposed to ionizing
radiation is not well represented by the average dose due to the small
number of discrete energy transfers involved. The energy deposited in
a microscopic volume can be determined by measuring the ionization in
a detector filled with gas at low...
