To learn more about the role β-galactosidase plays in rate of
acid production in milk by lactic acid bacteria, several lactobacilli
were examined for this enzyme. Cells from different species were
grown in lactose broth to induce β-galactosidase activity. The specific
activities of whole, solvent treated cells, and of cell-free...
To test the effects of kiln-drying on strength properties of Douglas fir and western hemlock, temperatures to 230 F, conditions for equilibrium moisture contents of 6 percent and 12 percent, and prolonged heating were investigated.
Prolonged heating and choice of conditions for 6 percent or 12 percent equilibrium moisture content...
This analysis is the study of Oregon's wildlife resources from
the period prior to white settlement up to the present time, including
critical projections, based on present trends and expected conditions
for both human and wildlife populations in the state up to the year 2010.
Prior to white settlement Oregon...
Several investigators have recently called attention to the
fact that the flux equation for water movement in unsaturated soils
may not be an appropriate mathematical model for the development
of the theory of unsaturated flow phenomena.
An analytical theory is developed for the purpose of testing
the validity of the...
The effect of a static quadrupole interaction on the 133-482 Kev
gamma-gamma angular correlation in Ta-181 has been studied by the
delayed coincidence method. Using a source of Hf-181 in polycrystalline
hafnium metal, the anisotropy was measured as a function of
time between the formation and decay of the 482...
