Researchers have investigated the associations between ammonia, air pollution, socioeconomic status, and access to medical care with incidence and mortality rates of salivary cancer in the South Carolina population. The findings from this study revealed that an association was found between emissions of ammonia and mortality rates of salivary gland cancer in Caucasian men.
Nearly 2,900 new cases of salivary gland cancer will be diagnosed in the United States in 2004, an increasing number, and no one knows why. Some studies suggest environmental factors may play a role, but no definitive data have been presented.
Ammonia is an agent that has been implicated in cancers of the stomach but is not known as a risk for salivary gland cancer. The study, “Salivary Gland Cancer Mortality and Industrial Ammonia Emissions: A Geographic Association,” examines that concept. The authors Edward D. Gorham, Ph.D, and Frank C. Garland, Ph.D both of the Naval Health Research Center San Diego, CA, and the Department of Family and Preventive Medicine University of California, San Diego, Terry Day, M.D, Medical University of South Carolina, Charleston, SC, Cedric F. Garland, Dr.P.H, Department of Family and Preventive Medicine University of California, San Diego, and Franky Hasibuan, M.P.H., GEO Centers, Inc., San Diego, CA, will present their findings at the 6th International Conference on Head and Neck Cancer being held August 7-11, 2004, at the Marriott Wardman Park in Washington, DC.

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...
