The production of high quality grass seed is important to the agricultural economy of the Grande Ronde Valley (GRV) of eastern Oregon. The predominate grass seed crops grown in the area are Kentucky bluegrass and fine fescues. Historically, open-field burning has been an effective, economical means by which to remove...
Yellow starthistle (Centaurea solstitialis L.) is a member of the knapweed
(Centaurea L.) complex. It is poor forage for all livestock and causes
“chewing disease,” a nervous disorder, in horses. Yellow starthistle infests
millions of acres in California and the Pacific Northwest. Infestations range
from scattered plants to dense stands...
Aromatic heterocycles are core structural motifs in natural products, pharmaceuticals and biological polymers. Indoles, in particular, represent a significant subclass of aromatic heterocycles, both in terms of sheer numbers, but also in biological and pharmaceutical relevance. As such, new methodologies for the synthesis of indoles represent an important and continually...
The crawfish enterprise of South Louisiana is shown to haveexpanded as much as 18-fold since the 1950's. It is estimated(1973) that there are about 44,000 acres of managed crawfish ponds.Of the 334 ponds identified and mapped in the thesis, 231 are classedas open ponds, 45 as rice field ponds, and...

California's Central Valley agricultural landscapes provide several important wintering regions for Pacific Flyway sandhill crane (Grus canadensis) populations; however, the value of those regions is being compromised by urban expansion, other developments, and conversions to incompatible crop types. Greater (G. c. tabida) and lesser sandhill cranes (G. c. canadensis) both...
An experimental packed distillation column was constructed
and data were taken to evaluate the effects of heating sections of the
column packing during the distillation operation. The experimental
column was packed with carbon Raschig rings and the heating was
accomplished using an induction coil. The carbon tetrachloride and
benzene system...
