The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Aqua satellite captured a visible image of Tropical Storm Rafael in the Atlantic Ocean on Oct. 14, 2012 at 1720 UTC (1:20 p.m. EDT). The image clearly showed that the bulk of Rafael's heaviest showers and thunderstorms were concentrated east of the center of circulation.

Those heavy showers are expected to bring between 1 and 3 inches of rainfall over the northern Leeward Islands with isolated totals to 12 inches. Flash flooding and mudslides are always a major concern with this kind of rainfall.
On Oct. 15 at 8 a.m. EDT, Rafael was approaching hurricane strength with maximum sustained winds near 70 mph (110 kph). It was located about 290 miles (465 km) north of San Juan, Puerto Rico, and 680 miles (1,090 miles) south of Bermuda near 22.5 North and 65.5 west. Rafael was moving to the north-northwest at 9 mph (15 kph) and is expected to turn to the north. Satellite imagery on Oct. 15 does not yet reveal an eye.
Forecasters at the National Hurricane Center expect Rafael to approach Bermuda late on Tuesday, Oct. 16.
Meanwhile, heavy surf and swells are expected the eastern facing beaches of the Bahamas, the northern Leeward Islands, and the north and east facing beaches of Puerto Rico. In a couple of days, Rafael will be moving into cooler waters and an area of higher wind shear, but is expected to intensify a little more before that time.
Rafael developed on Friday, Oct. 12 at 7:30 p.m. EDT from System 98L. When it organized into a tropical storm, it was located near 15.0 North and 63.1 West, about 125 miles (200 km) west-southwest of Domincia, causing tropical storm warnings in the U.S. Virgin Islands at that time. When Rafael developed, its maximum sustained winds were near 40 mph, and now forecasters are watching Rafael to see if the storm will become a hurricane.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
