Late, March 24, Omais strengthened to (63 mph) 55 knots and now that it has run into an environment with stronger wind shear, it has already weakened. The wind shear has increased because of the approach of a frontal system which is currently about 215 nautical miles northwest of the storm.
This morning at 0900 UTC (5 a.m. EDT) Omais' maximum sustained winds were down to 52 mph (45 knots). Omais, known in the Philippines as "Agaton," is now about 515 miles north-northwest of Palau, Micronesia, near 15.3 North and 131.5 East. It’s a slow moving storm, creeping along at 5 mph (4 knots) in a north-northwesterly direction.
As the storm continues to weaken, the reach of its tropical storm-force winds is expanding over a larger area. On March 24, tropical storm-force winds of 39 mph extended 30 miles out from the center. Now that Omais has weakened winds of that same strength extend as far as 65 miles from the center, so the area of tropical storm-force winds has more than doubled overnight.
The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite captured cold thunderstorm cloud tops in the center and southwestern corner of Tropical Storm Omais on March 25 at 12:41 a.m. EDT. The cluster of high thunderstorms on the southwestern edge is easily seen in today's AIRS visible image, as are the clouds associated with the cold front to the northwest of Omais.
As the cold front approaches, cooler and drier air associated with it will prevent cloud formation (and thunderstorm development), and vertical wind shear will increase. As a result, Omais is expected to dissipate over the next day and a half.

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...
