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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
