Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of funding agencies. Here we show how a global community is responding to the challenges of tropical ecosystem research with diverse teams measuring forests tree-by-tree in thousands of long-term plots. We review the major scientific discoveries of this work and show how this process is changing tropical forest science.

Op groenfestival Gardenista werd vorig jaar voor het eerst een postzegeltuincompetitie gehouden. Het tuintje dat de deelnemers moesten ontwerpen mocht niet groter zijn dan tien vierkante meter. Marc Hilhorst (24), student Tuin- en Landschapsinrichting aan hogeschool Van Hall Larenstein in Velp, kreeg de meeste publieksstemmen voor zijn 'Trópicos desérticos'.

The purpose of this study was to assess predictive value of a new submaximal rowing test (SmRT) on 2,000-m ergometer rowing time-trial performance in competitive rowers. In addition, the reliability of the SmRT was investigated. Twenty-four competitive male rowers participated in this study. After determining individual HRmax, all rowers performed an SmRT followed by a 2,000-m rowing ergometer time trial. In addition, the SmRT was performed 4 times (2 days in between) to determine the reliability. The SmRT consists of two 6-minute stages of rowing at 70 and 80% HRmax, followed by a 3-minute stage at 90% HRmax. Power was captured during the 3 stages, and 60 seconds of heart rate recovery (HRR60s) was measured directly after the third stage. Results showed that predictive value of power during the SmRT on 2,000-m rowing time also increased with stages. CVTEE% is 2.4, 1.9, and 1.3%. Pearson correlations (95% confidence interval [95% CI]) were −0.73 (−0.88 to −0.45), −0.80 (−0.94 to −0.67), and −0.93 (−0.97 to −0.84). 2,000-m rowing time and HRR60s showed no relationship. Reliability of power during the SmRT improved with the increasing intensity of the stages. The coefficient of variation (CVTEM%) was 9.2, 5.6, and 0.4%. Intraclass correlation coefficients (ICC) and 95% CI were 0.91 (0.78–0.97), 0.92 (0.81–0.97), and 0.99 (0.97–1.00). The CVTEM% and ICC of HRR60s were 8.1% and 0.93 (0.82–0.98). In conclusion, the data of this study shows that the SmRT is a reliable test that it is able to accurately predict 2,000-m rowing time on an ergometer. The SmRT is a practical and valuable submaximal test for rowers, which can potentially assist with monitoring, fine-tuning and optimizing training prescription in rowers.

Zuyd University of Applied Sciences (ZUYD) and partners will develop photoflow chemistry reaction set-ups that will be powered with light as sustainable energy source, and as such contribute to the transition of the current chemical industry to a climate neutral one. To develop these reaction set-ups, a consortium of partners from the Dutch, Belgian and German chemical and high-tech ecosystems will cover all aspects related to required hardware, e.g. transparent reactors and energy-efficient light sources, automation and multiphase reactions. The mix of partners from academia (University of Amsterdam: the Noël group), an applied research organization (TNO), Center of Expertise CHILL, ZUYD, the Brightlands Chemelot Campus and multiple companies (Beartree Automation, Chemtrix, Creaflow, Ecosynth, De Heer, Innosyn, Mettler-Toledo, Peschl Ultraviolet and Swagelok Nederland) ensures an efficient and integrated development along technology readiness levels (TRL) ranging from two/three to five/six. Together we will answer the overarching question: With which advanced reaction set-up(s) can we efficiently perform and further optimize multiphase solution-based photochemical reactions that require gas and/or solid reagents, and efficiently showcase our capabilities? The development of the advanced reaction set-ups will allow us to answer our research question: How far can we extend the applicability of photoflow transformations beyond the current commercial state-of-the-art by the use of advanced reaction set-ups? Dissemination of several demonstrator transformations using our advanced set-ups will showcase capabilities of Light-Up partners and speed up the uptake of photoflow chemistry in industry. We will develop the next generation of advanced reaction set-ups for photoflow chemistry by combining the knowledge of the chemical and high-tech sectors, and facilitating knowledge exchange between sectors, to contribute to a climate neutral industry.
Deze aanvraag betreft de productie van een viertal experimenten, uitgevoerd in samenwerking met MKB partners, op gebied van interactive storytelling voor 360 graden media. In deze video-experimenten gaat het om het testen van elementen voor de nieuwe beeldtaal, die vereist is voor 360 graden film. Gedurende de looptijd van het project worden drie symposia georganiseerd waarop alle betrokkenen de studies bespreken. Naast MKB hebben ook de omroepen VPRO en AVRO/TROS zich aan dit voorstel verbonden, alsmede de VU, UvA,TU Delft en de Nederlandse Filmacademie.
