Investigating conservation performance payments alongside human–wildlife conflicts: The Swedish lynx and wolverine protection policies

People and Nature, EarlyView.
Abstract Conservation performance payments are becoming an increasingly popular instrument to tackle human–wildlife conflicts. In Sweden, Sámi communities practicing reindeer husbandry receive performance payments as compensation for reindeer losses caused by lynxes and wolverines.

Prediction of Cure‐Induced Wrinkles Aimed at the Manufacturing of Large Wind Turbine Blades

Polymer Composites, EarlyView.
The step‐wise progression of the development of cure‐induced wrinkles. Before curing, at room temperature the laminate is resting at the mould face. In the next step, the wrinkle is developing due to thermal gradients. At the end of curing, the composite has cooled down and the undulation is left in, byt the increase in resin stiffness across the ...

Development of Vertical Wind Turbine Blades Using 4D Printing of Composites

Polymer Composites, EarlyView.
Vertical axis wind turbine: White blade: Commercial. Black blade: Composite. ABSTRACT This paper presents the procedure to make vertical wind turbine blades using the technique of 4D printing of composites (4DPC). The blades are made using carbon/epoxy composite materials with a fiber volume fraction of about 60%.

Integrating tunable LED‐induced plant responses with novel solar cell technologies for energy‐efficient agrivoltaic systems

PLANTS, PEOPLE, PLANET, EarlyView.
The increasing demand for sustainable food production requires innovative solutions that balance productivity, resource efficiency, and environmental impact. Vertical Farming Systems (VFSs) offer a promising approach; however, their high energy consumption remains challenging.

A new method to identify and explain sources of precipitation modification, illustrated for the western Netherlands

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and
