People wearing compression stockings on long-haul flights may have one tenth the risk of developing a deep vein thrombosis (DVT) compared to those who do not wear compression stockings. So concludes a systematic review of medical research to be published in The Cochrane Library, Issue 2, on April 19th 2006.
“This review shows that airline passengers travelling for long distances can expect a substantial reduction in the incidence of symptomless DVT if they wear compression stockings,” says lead Review Author Prof Mike Clarke, Director of the UK Cochrane Centre, Oxford.
DVTs are blood clots that partially or totally block veins running deep inside the body, usually in the legs. They have been of concern for years in patients lying in hospital beds, and more recently in passengers on aircraft. These people share a number of common features: both sets tend to become dehydrated and breathe air that has a low humidity, and both groups do not move about very much.

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...
