Due to the 2005 Nobel Prize in physiology and medicine received by Robin Warren and Barry Marshall, the name of the Helicobacter pylori bacterium is now a buzz word. According to contemporary overview, the bacterium gets into the stomach with food and water. In adverse conditions (stress, malnutrition, genetic factors, etc.), the bacterium invades the wall of the stomach or the duodenum under the mucous membrane and produces toxins destroying the walls. This is how gastritis originates, turning into ulcer.
It is fair to say that the Helicobacter pylori bacterium does not cause gastritis and ulcer with all their hosts. There will always be some percentage of people resistant to some bacterium or virus. But if gastritis or ulcer symptoms are clear, then it is sufficient to determine the Helicobacter pylori presence to start treatment (which is by the way well-developed).
Previously, to diagnose the disease, patients had to endure an extremely unpleasant procedure (gastroscopy) –swallowing a stomach pump. The procedure is not only unpleasant, but also dangerous: it traumatizes the larynx and esophagus. Besides, a stomach pump can bring some infection in the patient’s organism if it has not been properly sterilized.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
