A method for isolating the salt gland (SG) from the larval brine
shrimp has been developed. This extra-renal organ is removed from 5-10%
of Stage Inauplii by vortexing after incubating the animals at 37°C for
8 hours in a saline solution buffered with 100 mM sodium phosphate at pH
7.6....
In rodent models as well as in fish models there are significant
species differences in the susceptibility toward aflatoxin B₁ (AFB₁)
carcinogenesis. Mouse is less susceptible toward AFB₁ carcinogenesis
than rat. Researchers have come to the conclusion that the lower
susceptibility of mice is not a result of less effective...
Birth and pupping season records of Pacific harbor seals
(Phoca vitulina richardsi) were used in an analysis of
photoperiod effect on the timing of birth in this species. Dates
and latitudes of births were converted into photoperiods using a
photoperiod equation. Sequential dates from parturition were
converted into photoperiods and...
The design and construction of two new sample injection systems or nozzles, for use with the Oregon State electron diffraction apparatus are discussed. One of these nozzles was intended for use with volatile samples the vapors of which were to be heated or cooled over the range -196 to 540°C;...

This fifth annual Cooperative Pole Research Program report
outlines our progress in the six project objectives.
Improved Fumigants
Sampling of previously established field tests revealed that
Vorlex and Chloropicrin continued to perform well after 15 years,
while Vapam was slightly less effective. Solid methylisothiocyanate
(MIT) also performed well in the...
The inheritance mode of pea-resistance to the Lentil
Strain of Pea Seedborne Mosaic Virus (PSbMV-L) was
studied. In addition, commercial pea cultivars, Plant
Introduction (P.I.) lines and Oregon State University
(OSU) breeding lines were tested for susceptibility to
this virus. These lines were also tested for their
reaction to Bean...
The ability of controlled livestock grazing, in
combination with seeding of palatable forages, to reduce
understory competition and enhance conifer
establishment, was evaluated during 1985 and 1986, on
two adjacent sites in southwestern Oregon. In 1984,
Site 1 was clearcut and broadcast burned to remove
slash, and Site 2 was...
