wIRA increases tissue temperature (+2.7°C at a tissue depth of 2 cm), tissue oxygen partial pressure (+32% at a tissue depth of 2 cm) and tissue perfusion. These three factors are decisive for a sufficient supply of tissue with energy and oxygen and consequently also for wound healing and infection defense. wIRA acts both by thermal (related to heat energy transfer) and thermic as well as by non-thermal and non-thermic effects.
In a bilingual review article, just published on December 16th, 2009, in the medical e-Journal "GMS Krankenhaushygiene Interdisziplinär" within Open Access-portal "German Medical Science" of the AWMF (Association of the Scientific Medical Societies in Germany), working mechanisms of wIRA and results of 6 scientific studies with wIRA are discussed.wIRA can considerably alleviate pain (without any exception during 230 irradiations) with substantially less need for analgesics (52 - 69 % less in the groups with wIRA compared to the control groups). It also diminishes exudation and inflammation and can show positive immunomodulatory effects.
wIRA can advance wound healing or improve an impaired wound healing both in acute and in chronic wounds including infected wounds.
A median reduction of wound size of 90 % in severely burned children was already achieved after 9 days in the group with wIRA compared to 13 days in the control group.
With wIRA a wound closure and normalization of the thermographic image in otherwise recalcitrant chronic venous stasis ulcers was reached. The attached figure presents the successful healing process of a chronic venous stasis ulcer of the lower leg under therapy with wIRA. In a study with chronic venous stasis ulcers of the lower leg it lasted on average 18 days with wIRA versus 42 days without wIRA until complete wound closure.
wIRA represents a valuable therapy option and can generally be recommended for use in the treatment of acute as well as of chronic wounds.Publication (bilingual):

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...
