The Miridae, or plant bugs, associated with noble fir, Abies
procera Rehd., are discussed. Thirty six species of the Miridae were
collected from noble fir. Twenty five of these species are considered
only "visitors" to noble fir. The study does not deal with these
species. Noble fir is a host...
This study was designed to assess chiorpyrifos exposure of a group of farmers by determining internal dose associated with a given application of this insecticide. This involved the monitoring of urinary levels of 3,5,6 trichloro-2-pyridinol (TCP), the major metabolite of chlorpyrifos. Incidental exposure was evaluated by determining the levels of...

A note of caution is Provided to users of the widely-distributed Cox ocean circulation model. It is shown that the discrete conservation of vorticity equation associated with the finite difference approximations to the primitive equations on an Arakawa B grid contains a term that approximates βΔy²∂²u/∂x∂y. Although this term has...
A shell model for ferroelectric perovskites fitted to results of first-principles density functional theory (DFT) calculations is strongly affected by approximations made in the exchange-correlation functional within DFT, and in general not as accurate as a shell model derived from experimental data. We have developed an isotropic shell model for...
