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.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
