On Sunday, June 30, NASA infrared satellite imagery revealed tightly curved bands of thunderstorms over the southern quadrant of the storm were wrapping into the northern quadrant of the low-level center. However, in the northwestern quadrant, the quadrant that will make landfall first, there was a lack of strong convection and thunderstorms. Those satellite observations held true 24 hours later.
NASA’s TRMM satellite flew over Rumbia on July 1 at 12:12 a.m. EDT and noticed some areas of heavy rainfall (red) in bands of thunderstorms south of the center. Heavy rainfall was falling at rates of over 2 inches/50 mm per hour. Strong band of thunderstorms continued.

Typhoon Rumbia was located east of Hainan Island, China in South China Sea early on July 1. It is headed for landfall today, July 1, in southeastern China, south of Hong Kong.
When NASA’s Tropical Rainfall Measuring Mission or TRMM satellite flew over Rumbia on July 1 at 0412 UTC (12:12 a.m. EDT) the Precipitation Radar instrument noticed some areas of heavy rainfall in bands of thunderstorms south of the center of circulation. Heavy rainfall was falling at rates of over 2 inches/50 mm per hour. TRMM imagery continued to show the strong band of thunderstorms continued wrapping around the southern quadrant of the storm and into the low-level center.
On July 1 at 1500 UTC (11 a.m. EDT), Rumbia’s maximum sustained winds increased from 45 knots (52 mph) to 65 knots (74 mph/120 kph) making it a minimal typhoon. It was located near 20.3 north latitude and 110.9 east longitude, about 217 nautical miles southwest of Hong Kong. Rumbia is moving to the west-northwest at 13 knots (15 mph/24 kph).
Rumbia’s western quadrant is already interacting with the land of Hainan Island, China, breaking up the band of thunderstorms in that part of the storm. Because the interaction with land is already weakening the storm the forecasters at the Joint Typhoon Warning Center (JTWC) expect Rumbia to continue to weaken as it heads for landfall.
JTWC expects that Rumbia may make landfall near Zhanjiang, a prefecture-level city at the southwestern end of Guangdong province. Areas that Rumbia’s center are expected to pass near include Leizhou Bay and Zhanjiang Port.
Residents along southeastern China are already feeling the effects of Rumbia with tropical-storm force winds, heavy rainfall, flash flooding and very rough surf along the coasts.Rob Gutro

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
