Of the four representative species of the Mediterranean climate - the holm oak (Quercus ilex), the kermes oak (Quercus coccifera), the Aleppo pine (Pinus halepensis), and the Phoenician juniper (Juniperus phoenicea) - the last is the one which best adapts to the adverse conditions of water stress. However, this does not mean the disappearance of the other three species that have been studied. This is the conclusion drawn from his PhD by Francisco Javier Baquedano, agricultural engineer at the Public University of Navarre.
The study was centred on the Mediterranean area, a transition climatic region where weather effects are more pronounced, involving a climate characterised by a long, hot, dry summer. The summer drought coincides with a high evaporative factor and this is why it is considered as the most important factor limiting the production, growth and distribution of plants in the Mediterranean ecosystems.
The survival of plants under these adverse conditions greatly depends on their ability to compensate for loss of water and to their carbon-fixing properties. The balance between these two processes could be the key to the competition between the species and consequently, to the relative presence of flora in the ecosystems. It has also been suggested that the winter, cold and with little precipitation, influences in an important manner the development and distribution of the Mediterranean perennial species.

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.
