The earlier the smoke in a forest will be detected, the easier it would be for firemen to stop the fire from spreading. The problem of forest fires have always been one of the most difficult and dangerous problems. Russian scientists from MULTITECH Ltd. have developed an equipment, which can help solving the problem.
Right now the equipment is not of much use, because autumn rains have already quenched forest and turf fires. However, if the scientists put their invention to industrial production by the next summer, it will really improve the situation. Laser beam can easily detect a fire and then, if needed, alarm the operator at the central control. A single LID-Er, as it was named, can observe a square up to 100 thousand hectares.
A strong laser beam periodically controls atmosphere conditions. Smoke is opaque for laser light, so the beam reflects back. A special telescopic system "catches" the signal, amplifies it and sends to computer. If after several minutes (on the second pass) the smoke is detected once more at the same point, computer will compare intensities of first and second signals, taking more measures if needed and carrying out the process dynamics. If the smoke density gradually increases, the computer will send an alarm signal to the operators desk. Then its up to the operator to decides, whether to send a firemen brigade to the dangerous place.

Understanding animal social networks can aid wildlife conservation

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
