Parks are necessary for sustainable urban vitality. We studied the optimal availability of parks by combining open data sets with polygons and classification frameworks from urban planning literature. Both distance and population density should be considered as measures of availability when planning urban parks.

Since the European Union wants to reduce the oil dependence of the transportation system, the uptake of alternative vehicle technologies are stimulated in the member states. In the Netherlands, stimulation is already largely implemented in the form of a comprehensive charging infrastructure. This infrastructure is widely used by the electric vehicle drivers and thus there may occur a form of competition for the charging points. In this paper we address this problem by predicting the short-term availability of charging points at a given location and time by using the historical charging data in a space-time series model. The model shows better accuracy with respect to a naive method for short term predictions up to one day. This will allow charging point operators to provide customers with the service of looking up estimated charging point availability in the nearby future.
Objective: Frequent high caloric intake (snacking) induces overweight. The aim of this study was to examine the impact of social and physical environmental factors on the snacking behavior of adolescents. Design: cross-sectional population based study Method: Snacking behavior of individuals and their peer-group members (cliques) was assessed in 749 adolescents (398 girls, 351 boys, mean age 14.9, range 12.4 - 17.6 years). Snack and soft drink availability at school were observed. In hierarchical stepwise regression analysis, clique consumption, snack and soft drink availability at school, and person characteristics (age, gender, education level, and body mass index), were examined as determinants of snacking behavior. Individual consumption was also predicted from clique consumption combined with school availability and person characteristics. Results: Snack and soft drink consumption was higher in boys than in girls, soft drink consumption was higher in adolescents with lower education, and snack consumption was lower in adolescents with a lower body weight. Clique snack and soft drink consumption were associated with individual snack and soft drink intake, particularly in case of more availability of snacks and soft drinks, and in boys, adolescents with a lower education level and adolescents with lower body weights. Conclusion: More snacking in adolescents is associated with more snacking in the peer group they belong to, especially in schools with high availability of snacks and soft drinks, in boys, and in lower educated or normal weight adolescents. These findings offer opportunities for influencing individual behavior by preventive programs e.g., by peer education in targeted groups. Future research is suggested for evaluating the potential effect of such programs.
Our unilateral diet has resulted in a deficiency of specific elements/components needed for well-functioning of the human body. Especially the element magnesium is low in our processed food and results in neuronal and muscular malfunctioning, problems in bone heath/strength, and increased chances of diabetes, depression and cardiovascular diseases. Furthermore, it has also been recognized that magnesium plays an important role in cognitive functioning (impairment and enhancement), especially for people suffering from neurodegenerative diseases (Parkinson disease, Alzheimer, etc). Recently, it has been reported that magnesium addition positively effects sleep and calmness (anti-stress). In order to increase the bioavailability of magnesium cations, organic acids such as citrate, glycerophosphate and glycinate are often used as counterions. However, the magnesium supplements that are currently on the market still suffer from low bio-availability and often do not enter the brain significantly.The preparation of dual/multiple ligands of magnesium in which the organic acid not only functions as a carrier but also has synergistically/complementary biological effects is widely unexplored and needs further development. As a result, there is a strong need for dual/multiple magnesium supplements that are non-toxic, stable, prepared via an economically and ecologically attractive route, resulting in high bioavailability of magnesium in vivo, preferably positively influencing cognition/concentration
Goal: In 2030 the availability of high quality and fit-for-purpose recycled plastics has been significantly increased by implementation of InReP’s main result: Development of technologies in sorting, mechanical and chemical recycling that make high quality recycled plastics available for the two dominating polymer types; polyolefins (PE/PP) and PET. Results: Our integrated approach in the recycling of plastics will result in systemic (R1) and technological solutions for sorting & washing of plastic waste (R2), mechanical (R3) and chemical recycling (R4, R6) and upcycling (R5, R7) of polyolefins (PE & PP) and polyesters (PET). The obtained knowledge on the production of high quality recycled plastics can easily be transferred to the recycling of other plastic waste streams. Furthermore, our project aims to progress several processes (optimized sorting and washing, mechanical recycling of PP/PE, glycolysis of PET, naphtha from PP/PE and preparation of valuable monomers from PP/PET) to prototype and/or improved performance at existing pilot facilities. Our initiative will boost the attractiveness of recycling, contribute to the circular transition (technical, social, economic), increase the competitiveness of companies involved within the consortium and encourage academic research and education within this field.
In the last decade, the automotive industry has seen significant advancements in technology (Advanced Driver Assistance Systems (ADAS) and autonomous vehicles) that presents the opportunity to improve traffic safety, efficiency, and comfort. However, the lack of drivers’ knowledge (such as risks, benefits, capabilities, limitations, and components) and confusion (i.e., multiple systems that have similar but not identical functions with different names) concerning the vehicle technology still prevails and thus, limiting the safety potential. The usual sources (such as the owner’s manual, instructions from a sales representative, online forums, and post-purchase training) do not provide adequate and sustainable knowledge to drivers concerning ADAS. Additionally, existing driving training and examinations focus mainly on unassisted driving and are practically unchanged for 30 years. Therefore, where and how drivers should obtain the necessary skills and knowledge for safely and effectively using ADAS? The proposed KIEM project AMIGO aims to create a training framework for learner drivers by combining classroom, online/virtual, and on-the-road training modules for imparting adequate knowledge and skills (such as risk assessment, handling in safety-critical and take-over transitions, and self-evaluation). AMIGO will also develop an assessment procedure to evaluate the impact of ADAS training on drivers’ skills and knowledge by defining key performance indicators (KPIs) using in-vehicle data, eye-tracking data, and subjective measures. For practical reasons, AMIGO will focus on either lane-keeping assistance (LKA) or adaptive cruise control (ACC) for framework development and testing, depending on the system availability. The insights obtained from this project will serve as a foundation for a subsequent research project, which will expand the AMIGO framework to other ADAS systems (e.g., mandatory ADAS systems in new cars from 2020 onwards) and specific driver target groups, such as the elderly and novice.
