NASA's Tropical Rainfall Measuring Mission (TRMM) satellite captured rainfall data on Prapiroon twice on Oct. 18 when it passed overhead. The first orbit was at 0845UTC and the second at 1019 UTC. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data show that rain associated with Prapiroon was falling at a rate of over 75mm/hour (~3 inches) in a feeder band northwest of the center of circulation.
Prapiroon's winds had dropped to less than 35 knots (~40 mph) when the TRMM data were collected on Oct. 18. Despite the drop in wind speed, some powerful thunderstorms around Prapiroon's center were still reaching heights above 12 kilometers (~7.6 miles).

Some of the rainfall occurring over Japan on Oct. 18 was being caused by a frontal system that was interacting with tropical Storm Prapiroon.
At NASA's Goddard Space Flight Center in Greenbelt, Md., Hal Pierce of the TRMM team created a 3-D image of the storm using TRMM PR data received with the 1019 UTC (6:19 a.m. EDT) orbit. Prapiroon was once a powerful typhoon with winds of 100 knots (~115 mph). Prapiroon's winds had dropped to less than 35 knots (~40 mph/65 kph) when the TRMM data were collected. Despite the drop in wind speed, some powerful thunderstorms around Prapiroon's center were still reaching heights above 12 kilometers (~7.6 miles).
By 1500 UTC on Oct. 18, Prapiroon's maximum sustained winds dropped near 35 knots (40 mph/65 kph). Tropical storm Prapiroon was, located approximately 325 nautical miles south-southwest of yokosuka, japan, near 30.9 North latitude and 138.9 East longitude. The storm has accelerated northeastward at 33 knots (38 mph/62 kph) .
Just five hours after the second TRMM satellite overpass, the Joint Typhoon Warning Center noted that "animated infrared satellite imagery showed deep central convection has unraveled and sheared north of the low level circulation center."
Prapiroon is undergoing transitioning while battling strong wind shear and is expected to become extra-tropical by Oct. 19.

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...
