Factors influencing pesticide susceptibility and
resistance were studied in Psylla pyricola Foerster, and
its mirid predator, Deraeocoris brevis Knight in the
Rogue River Valley, Oregon. Factors studied were at the
biochemical, life history, and population ecology
levels.
Studies on detoxification enzymes showed that
glutathione S-transferase and cytochrome P-450
monooxygenase activities...
Himalayan collision produced frontal and lateral
ramps and associated Pliocene to Quaternary tectonic
geomorphic features in the foreland fold-thrust belt of
northwestern Pakistan. The transpressional right-lateral
Kalabagh tear fault zone displaced the emergent Surghar
Range frontal thrust from the western Salt Range by 16-19
km since 1.9-2.1 Ma: the age...
An experimental investigation was carried out to
determine the thermodynamics and fluid mechanics of the
pipe flow of magnetic fluids. A water-based magnetic
fluid was synthesized in the laboratory and its relative
viscosity and magnetic properties were determined
as a function of temperature. A "thermomagnetic pump"
was built and tested...
