This study was to investigate effects of growth rate
and cambial age on properties of wood from two increasingly
used hardwood species, red alder (Alnus rubra Bong.) and
Oregon white oak (Quercus garryana Dougl.), for better
understanding factors affecting wood quality in hardwoods.
Thirty 7-year-old trees grown at widely varying...
A study was conducted to identify geographical variation in loblolly pine bark and wood properties at the whole-tree level and to quantify the responses in whole-tree
bark and wood properties following contrasting silvicultural practices that included planting density, weed control, and fertilization. Trees were destructively sampled from
both conventionally managed...
Reforesting harvested lands in southwestern Oregon has been
difficult because of low rainfall, high evaporative demand, and
competitive understory vegetation. Herbicides have been a preferred
method to control competing vegetation but herbicide use on federal
lands was curtailed in 1984. As a result, interest in livestock
grazing as a vegetation...
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....
Novel mucosal vaccines (LL-M2e, LL-HAe, SG-HAe) were constructed from live, non-pathogenic Lactococcus lactis or Streptococcus gordonii that express conserved regions of HA or M2 antigens from avian influenza virus (AIV) A. All three vaccines evoked antigen-specific serum immunoglobulin G (IgG) responses in vaccinated chickens. The addition of the adjuvant cholera...
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...
Reflux condensation tests examining steam condensation in a PWR steam
generator (SG) were conducted at the Oregon State University (OSU) Advanced
Plant Experiment (APEX) Test Facility from 2005 through 2007. The
experimental data collected will provide a basis to assess TRACE steam generator
modeling techniques and assist in development of...

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...
