Studies were conducted to establish some characters which
could be used, either in the field or in the laboratory, to differentiate
between annual ryegrass (Oregon), Lolium multiflorum Lam. , and
Linn perennial ryegrass, Lolium perenne L.
Vernation, percentage of glumes covering the spikelets, and
height of seedlings seem to be...
Oregon State University operates a World-Wide Standard Seismograph
Station at Corvallis (COR) and a seismic station at Klamath Falls (KFO),
Oregon.
The Corvallis station includes
graphs (T0 = 1 sec , Tg = 0.75 sec),
seismographs (T0 = 30 sec t Tg = 100
vertical Benioff seismograph (T0 =

The reactions of EGTA, [ethylene bis (oxyethylenenitrilo)]
tetraacetic acid, with 51 metal ions have been studied spectrophotometrically in aqueous solutions.
The absorption spectra of the
chelates formed were measured with a recording spectrophotometer
between 200 and 700 mμ. The pH of each solution was varied and a
spectrum was scanned...
In view of the stimulant effects of gibberellic acid on plant
growth, and its interesting modifications of various metabolic products,
it was decided to determine whether this growth regulator
would induce a favorable effect on total alkaloid production, especially
on the antineoplastic alkaloids, of Catharanthus roseus (L.) G. Don
(Vinca...
The processes responsible for transporting and depositing thick
sections of coarse-grained terrigenous clastics on the abyssal floor
and for forming associated sedimentary structures are still conjectural.
Many workers attribute coarse deep-sea sediments and their
probable lithified equivalent, the graywackes of flysch deposits to
some type of density movement.
Deductions concerning...
