Between 1967 and 1973, California, Oregon,
and Washington all established state-wide systems for
the preservation of land in its natural state. These
set aside parcels of land may be termed as Natural
Area Preserves. The history of each state's public
systems, different establishment procedures, and
management policies are discussed.
The experimental measurements of the decay heat from
the products of the thermal fission of U-235 have been compared
with the OSU-proposed decay heat standard. These experiments
are intended to verify the decay heat calculational
methods and nuclear data files. The comparisons have
included the previous experiments reviewed by Perry...
Self-recording instruments were installed in the Drake Passage in February 1975. Approximately one-half were part of a short-term array (3 + weeks) and were all successfully recovered in March 1975. The remainder are part of the long-term array which was recovered in January 1976.
The short-term array consisted of 2...
The development of the energy crisis has caused the
use of depletable energy resources to be monitored quite
closely in the United States. Within the agricultural
sector, irrigation is a large user of energy, with the
potential of using many times more energy than all other
agricultural field operations. A...
A continuous amperometric monitor for aqueous sulfite solutions
has been developed employing the electro-oxidation of sulfur (IV)
in 0. 1 M sulfuric acid at a glassy carbon test electrode. The monitor
employs a hydrodynamic flow cell, in which the solution stream
enters the cell through an orifice impinging on the...
Baseline data for the first year of a two-year study to assess
