Study of U.S. Travelers to Mexico and Guatemala Found 65 Percent Prevalence Rate
A majority of traveler’s diarrhea cases among U.S. travelers to Mexico and Guatemala were attributed to Norovirus, a common cause of nonbacterial gastroenteritis outbreaks usually associated with developed countries, according to a new study by researchers at the Johns Hopkins Bloomberg School of Public Health and other institutions. The researchers also found that the longer travelers stayed at their destination, the more likely they were to contract Norovirus infections. The study is published in the March 2005 issue of the Journal of Clinical Microbiology.
"Noroviruses are known to be a major cause of food and waterborne gastronteritis outbreaks in domestic and unique settings, such as cruise ships, and also have been documented among military groups during deployment overseas. However, few studies have investigated the prevalence of Norovirus infection among civilians traveling from industrialized to developing countries,” said Kellogg J. Schwab, PhD, corresponding author of the study and an assistant professor in the Department of Environmental Health Sciences at the Johns Hopkins Bloomberg School of Public Health.

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...
