Ontario launches controversial smog trading program

California launches nation's first green chemistry program.

ger's (R-CA) signature on Sep-tember 29, California became the first U.S. state to approve two laws that will move its regulatory scheme toward a comprehensive chemicals policy. The legislation is intended to improve public and environmental health protection and encourage green chemistry-the design of chemical products and processes that reduce or eliminate the use or generation of hazardous s...

Estimated emission reductions from California's enhanced Smog Check program.

The U.S. Environmental Protection Agency requires that states evaluate the effectiveness of their vehicle emissions inspection and maintenance (I/M) programs. This study demonstrates an evaluation approach that estimates mass emission reductions over time and includes the effect of I/M on vehicle deterioration. It includes a quantitative assessment of benefits from pre-inspection maintenance an...

The Joint Commission launches new comprehensive stroke certification program.

requires varying degrees of care and intervention because it affects individuals in different ways. To improve the quality and safety of care for patients with complex strokes—who require more specialized diagnostic testing, interventions, and care than those receiving care at Primary Stroke Centers (PSCs)—The Joint Commission developed a new Disease-Specific Care Advanced Certification program...

WHO launches global program for safe surgery, with checklist.

Reportrapport Steering Smog Prediction Steering Smog Prediction

The use of computational steering for smog prediction is described. This application is representative for many underlying issues found in steering high performance applications: high computing times, large data sets, and many di erent input parameters. After a short description of the smog prediction model, its visualization and steering are described. The amount of computation needed to solve...
