Important rivers usually have a number of tributary streams which have their sources in the mountains. It is not just water that goes on the journey but sediments, stones and other material. These materials are transported dissolved, in suspension or deposited as sediment at the bottom of the river.
A research team from the Department of Geodynamics at the University of the Basque Country (EHU-UPV) have begun a study in order to find out the amount of sediments transported from the three main river basins of the province of Gipuzkoa in the Basque Country, i.e. the Urola, Urumea and Deba river basins. The aim is to analyse how factors, both natural and non-natural, affect the presence and the transport of these sediments in these waters.
To this end, the upper basins of the aforementioned rivers were selected: Añarbe in the case of the Urumea river, Barrendiola in the case of river Urola and Aixola in the case of the Deba. These three basins were chosen after an exhaustive analysis of their physical parameters (geology, geomorphology, vegetation, hydrology, soils, and so on). Moreover, the three basins have different characteristics and, thus, are representative of different environments in Gipuzkoa.

Russian researchers together with their French colleagues discovered that a genuine feature of superconductors -- quantum Abrikosov vortices of supercurrent -- can also exist in an ordinary nonsuperconducting metal put into contact with a superconductor. The observation of these vortices provides direct evidence of induced quantum coherence. The pioneering experimental observation was supported by a first-ever numerical model that describes the induced vortices in finer detail.
These fundamental results, published in the journal Nature Communications, enable a better understanding and description of the processes occurring at the...
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.
