A deadly combination of industry and human activity may soon wipe out Albertas grizzly bear population, but new University of Alberta research that identifies the provinces highest mortality spots.
Scott Nielsen, from the Department of Biological Sciences, has isolated specific spots where the bears are dying at the highest rates, all sites where grizzly habitats overlap areas that humans frequent regularly. Nielsens paper, published in the journal "Biological Conservation" is one of the first to map out these dangerous locations. Until now, research has concentrated on mapping habitat alone.
The biggest culprit, said Nielsen, is when industry--forestry, oil and gas, and mining--extract resources, since each activity develops a new network of roads to access this property. Grizzly bears already are low in number and have very low productive rates, so even when a small number of bears are killed, it can have significant consequences on the species. "Mortality rates in many sites are simply way too high to expect long-term persistence of grizzly bears," said Nielsen, the lead author on the paper. "Methods that identify mortality sites in most need of management or restoration are needed."

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.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
