The capture of pine engravers, Ips pini (Say j, in ipdienol-baited, multiple-funnel traps in British Columbia was significantly reduced when devices releasing ipsenol or verbenone were placed in the traps. These results suggest that ipsenol and verbenone are synomones released by Ips latidens (LeC.) and the mountain pine beetle, Dendroctonus ponderosae(More)
Wise and effective woody plant management is an increasing necessity for many land uses and conservation pcti~es, especially on forests and rangelands whe& native or exotic plants are affecting productiviry, access, or critical habitat Tools and approaches for managing woody plants have been under concerted development for the past 50 years, integrating(More)
A cademic CS departments have experienced large increases in undergraduate and graduate enrollments dur-A ing the first half of the 1980s. In order to handle the increases , universities have allocated significant new funds to CS, and this in turn has caused significant growth in the number of departments and their sizes. After almost 10 years in the 1970s(More)
Fully nonlinear modulation equations are presented that govern the slow evolution of single-phase harmonic wavetrains under a large family of spatially discrete nonintegrable ows, among which is the discrete nonlinear Schrr odinger equation(DNLS). These modulationequations are a pair of partial diierential equations in conservation form that are hyperbolic(More)
There is as yet no consensus regarding how best to quantify alcohol consumption as an outcome measure in treatment research. Two commonly used methods were compared: the timeline follow-back procedure which reconstructs daily drinking via a calendar, and the grid averaging method employed in the Drinker Profile system. A sample of outpatients being treated(More)
