Recently, the big sagebrush taxa has been split into subspecies
and forms. Four habitat types related to subspecies of big sagebrush
were studied in Eastern Oregon. Response of understory vegetation was
measured following three range improvement techniques implemented on
the four habitat types for several ages of treatment. Crown cover,...
The effects of mass flow rate and subchannel configuration on
the turbulent interchange between adjacent subchannel in simulated
rod bundle were investigated.
The simulated rod bundle was made by arranging seven 1.913 cm
diameter acrylic plastic rods in an equilateral triangular pattern in a
tube 8.89 cm inside diameter.
The...
Douglas-fir bark was extracted with n-hexane. A light-colored
"wax-like" solid was recovered from the extract by evaporation of
the solvent. Chemically intact sterol esters and ferulic acid esters
were isolated from the "wax" without saponification or degradation
as had been necessary in former investigations. The characterization
of the intact esters...
