While biomedical devices such as prosthetic heart valves, heart-assist devices, oxygenators, vascular grafts and hemodialysis systems can help to save or significantly extend lives, these same devices also can damage the blood cells which travel through them. Severe consequences can result when blood cells are damaged or broken down, said Marina Kameneva, Ph.D., research associate professor of surgery at the University of Pittsburgh School of Medicine.
Dr. Kameneva will discuss the issue in a plenary lecture on "hemorheological aspects of flow induced blood trauma in artificial organs" on Sept. 26 during a joint meeting of the 11th International Congress of Biorheology and the 4th International Conference on Clinical Hemorheology in Antalya, Turkey. Rheology is the science of the deformation and flow of matter.
"Biomedical devices are widely used to repair or replace a number of cardiovascular system elements," said Dr. Kameneva, a scientist at the University of Pittsburghs McGowan Institute for Regenerative Medicine who is one of the few working worldwide whose research focuses on fluid dynamics and artificial blood products. "The successful functioning of these devices strongly depends on the way they disturb blood."

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...
