Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
This means that the sensor needs not even a single wire, nor a battery that would have to be replaced. The arrival of such sensors is an important development…

The innovation is a device for workpiece orientation that exactly positions the tool during the transformation process for its adaption. (E.g. sawing, bending, welding, drilling, grinding, etc
The present invention includes a measuring system which is specifically engineered for the attachment of the device “Polar Equine RS800 CX” to large animals. It consists of an elastic stretch material which does not restrict the freedom of movement and breathing during the measurement. The measuring belt contains wide velcro-fastener and buckle systems and can thus be adapted to the individual chest sizes of large animals. It also contains leather bags in which the electrodes, the transmitter and, if necessary, the receiver can be stowed in order to protect them from environmental influences. The leather bags are attached to the measuring belt by using velcrostraps. Thereby they can be positioned variably along the belt at different positions. The belt system has already been completed with the help of a saddler. Its function – especially its fitting – has been proven in case of longterm measurements (for example over a period of 24 hours). It is also be suited for field measurements.
The observations were performed with the Event Horizon Telescope (EHT) bringing together a network of telescopes at millimeter wavelengths. They show not only…

Teach-In-Programming of robots is faced with a fundamental challenge: binding in external hardware und synchronizing robots with diverse hardware components within a simple programming environment. The present solution allows for intuitive programming of multiple robots and adapting existing programs from pre-existing offline programming. Movements and other actions are displayed in a clear diagram representation, from which movement durations or cycle time lines can be seen. There is the possibility to synchronize different components and to edit the recording of movements and to train (“teach-in”).

The newly developed sheet metal composite material can be used for a wide range of applications in the automotive sector as well as in the field of mechanical engineering and manufacturing of deep-drawn part. In relation to its weight, the material possesses a high level of rigidity which can be adjusted to meet specific requirements.
The new hybrid material consists of two individual panels bonded via a viscoelastic layer, which has damping properties. Because the material has one plane outer surface paint finish can be applied and flow properties can be enhanced by adding nanostructures, for example.
Researchers from Goethe University Frankfurt am Main have developed a portfolio of silylene-based chemistry allowing for the synthesis of defined oligo- and polysilanes from trichlorosilane and hexachlorodisilane. The combination of the new technologies offers an alternative to the conventional energy-consuming silicon chemistry and access to new compounds.
The researchers, based at the University of Belgrade, Serbia, created a vibrating membrane – the part of a condenser microphone which converts the sound to a…
