A two-dimensional, frictionless, nonlinear model of coastal upwelling is reexamined. The model has been solved previously at steady state and as an initial-value problem. The previous solution to the initial-value problem is inconsistent with the steady-state solution. A new solution to the spinup problem is presented that approaches the existing...
I examined, in three separate studies, the active chromatin
structure of the yeast, Saccharomyces cerevisiae.
Yeast contains four proteins having amino acid compositions
typical of the high mobility group (HMG) proteins. Three of these
are eluted from chromatin by 0.35 M NaCl; one is not, but is eluted
by 0.25...
A permanent study was established in 1970 and 1971 to measure the impact, spread, and intensification of dwarf mistletoe on precommercially thinned Douglas-fir and lodgepole pine in Montana. Mean diameter growth on all plots was reduced 21 percent in Douglas-fir, but the reduction is only significant at the 0.15 level....
To determine whether a homologous neurohormone, arginine
vasotocin (AVT), can elevate the occurrence of clasping behavior in
male rough-skinned newts (Taricha granulosa), intact, sexually inactive
males were injected with either AVT or saline. The incidence
of courtship was elevated in the group of males injected with AVT,
but not in...
The number of varieties of ryegrass (Lolium spp.) has increased greatly in recent years. An accurate and rapid laboratory technique to identify these varieties would benefit the consumer as well as protect an organization's Plant Variety Protection rights. There is also a need for a technique to complement the seedling...
