Douglas fir bark fines which contained 74.8 percent
of Klason lignin and 70.2 percent of one percent sodium
hydroxide solubility and decayed Douglas fir wood which
contained 53.9 percent of Klason lignin were subjected to
ethanolysis. A slight modification of the Hibbert's
ethanolysis procedure was used. The monomeric compounds
present...
The author studies the class of rectangular arrangements in
terms of two binary relations on the objects of the arrangement.
He shows how a univalent matrix determines a unique rectangular
arrangement, and how each rectangular arrangement is associated
with one, two, or four distinct matrices, according to the number
of...
Because of the organic nature and the natural foaming characteristics
of kraft mill effluents, it was decided to investigate the
feasibility of using foam separation as a method of treatment. The
treatment efficiency was evaluated by BOD and COD reductions as
well as the decrease in toxicity to marine life....
This thesis deals with the effect of pressure coupling on the
stresses in shells having geometric discontinuities. The problems
are, 1) cylinder with an axially symmetric thickness change and
2) cylinder with a hemispherical end closure. Solutions to the
above problems are based on differential equations that included the
straightening...
Manganese has been known to be essential for photosynthesis
for almost 30 years. Subsequent experimentation
indicated a definite function for manganese in oxygen evolution.
However, the mode of action of manganese and
further localization of its site of action have not been
determined.
Ten years ago it was demonstrated that...
The evaluation of social investment in water pollution control
has been retarded by a lack of methodology with which to evaluate
the direct benefits. The objective of this dissertation was to develop
theory and methodology for estimating direct recreational benefits
associated with the protection of sport fisheries. An inter-disciplinary
case...
