But first study of indoor air before and after a smoking ban finds carcinogens eliminated by smoke-free laws
The level of cancer-causing particles is much higher in the air of smoke-filled bars and casinos than on truck-choked highways and city streets, according to the first published comparison of indoor air quality before and after smoke-free workplace legislation. The study, conducted in a casino, six bars and a pool hall in Wilmington, Delaware, is published in the September 2004 Journal of Occupational & Environmental Medicine.
"This research clearly shows that it is far worse for your health to be a bartender or casino dealer in a smoking-permitted establishment than it is to be a turnpike toll collector," says James L. Repace, MSc., the study’s author. "These workers breathe an average of 90% cleaner air after a smoke-free workplace law." Repace, a health physicist, is visiting assistant clinical professor at Boston’s Tufts University School of Medicine and a secondhand smoke consultant based in Bowie, Md. In 2002, Repace received a Robert Wood Johnson Foundation Innovators Combating Substance Abuse award for his ground-breaking work on the effects of secondhand smoke. Funds from the award helped make this study possible.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
