Current government policy is failing to protect traditional Dutch landscapes says Dutch researcher Evelien van Rij. Green areas in the Randstad region with cultural historic value will disappear unless specific agricultural policy is developed for them. This will require both considerable investments and sufficient legislation from the Dutch government.
Evelien van Rij investigated possible improvements to rules and policy programmes for green areas on urban fringes. Her most important recommendation is that a distinction should be made in agricultural policy between traditional Dutch landscapes which are used for recreation in the Randstad region, and other agricultural areas in the rest of the Netherlands.Long-term planning
The doctoral research ’Improving institutions for green landscapes in metropolitan areas’ was carried out at the OTB Research Institute of Delft University of Technology as part of the NWO programme Social Scientific Research into Nature and the Environment (GaMON). The research is affiliated to the Habiforum programme Innovative use of space.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
