The Cooperative continues to actively
address a diverse array of issues related to
the effective use of wood utility poles.
The trials to evaluate the effectiveness of
MITC-Fume are now in their seventh year
and continue to show that methylisothiocyanate
(MITC) levels in MITC-Fume
treatments remain higher than comparable
metham...
Evaluations of previously established field trials indicate that
chioropicrin, and Vorlex continue to provide protection to Douglas-fir poles,
although the degree of protection is diminishing. Reapplication of Vapam 18
years after the initial application eliminated fungi which had recolonized the
poles. Methylisothiocyanate (MITC) continues to protect Douglas-fir poles 12
years...
Evaluation of previously established
field trials of remedial internal treatments
demonstrates the continued performance of
chioropicrin, Vorlex, and
methylisothiocyanate (MITC). While the
degree of protection afforded by these
treatments has declined with time, residual
fungitoxic levels remain in many tests.
Field trials of gelatin encapsulated MITC
indicate that gelatin had...

Evaluation of previously established
field trials of internal remedial treatments
continues to verify the excellent long-term
protection afforded by these treatments.
Field trials with gell encapsulated
methylisothiocyanate (MITC) demonstrate
that gelatin does not interfere with
chemical release, nor is addition of
supplemental moisture required for release.
Field trials have been...
Previously established field trials of
MTTC-Fume continue to show that this
chemical remains in Douglas-fir and southern
pine poles at fungitoxic levels 5 years after
treatment. In general, increasing dosages
resulted in higher chemical levels in the poles.
All of the MITC-Fume treatments resulted in
higher residual M1TC levels than...
Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are polyunsaturated fatty acids required for proper embryonic development, specifically neurodevelopment. However, little is known regarding their conversion to other metabolites during embryogenesis. The oxidation of ARA gives rise to the biologically active eicosanoids and the oxidation of DHA gives rise to the...
Blackside dace, Rhinichthys osculus nubilus (GIRARD), were
collected from ten western Oregon streams and examined for variation
among morphological and meristic characters. Several characters were
observed to vary between populations studied. Number of vertebrae,
number of scales in and above the lateral line, length of snout, and
depth of body...
