Er lijkt een duidelijke mate van evidentie te bestaan betreffende de relatie fysieke activiteit, respectievelijk fitheid en gezondheid in de algemene populatie en bij bepaalde pathologieën. Er is evenwel nog behoefte aan verder wetenschappelijk onderzoek naar mogelijke determinanten en onderliggende mechanismen, als ook naar evidentie bij bepaalde, specifieke aandoeningen. Tevens mag duidelijk zijn dat ondanks de bestaande evidentie fysieke activiteit/oefening te weinig toegepast wordt in de gezondheidszorg. Het onderzoek naar de effectiviteit van gezondheidskundige interventies is dan ook uitermate belangrijk. Dit lectoraat hoopt dan ook een bescheiden bijdrage hieraan te kunnen leveren. Hiervoor heeft zij reeds afspraken tot samenwerking met de academische en medische wereld (in Utrecht, Amsterdam, Maastricht en Leuven), met de gezondheidszorg (RIVM Bilthoven en GG&GD Utrecht) en met de beroepen- of bedrijfswereld (Politie regio Utrecht; Enraf Nonius, Delft). De beoogde doelstellingen zullen echter naar alle waarschijnlijkheid beduidend meer tijd in beslag nemen dan de periode van 4 jaar die de Stichting Kennis Ontwikkeling voorzien heeft met betrekking tot het oprichten en financieren van de lectoraten.
CC-BY 4.0 Background: Since the contribution of the lumbar multifidus(LM) is not well understood in relation to nonspecific low back pain(LBP), this may limit physiotherapists in choosing the most appropriate treatment strategy.Objectives: This study aims to compare clinical characteristics, in terms of LM function and morphology, between subacute and chronic LBP patients from a large clinical practice cohort compared to healthy controls.Design: Multicenter case control study.Method: Subacute and chronic LBP patients and healthy controls between 18 and 65 years of age were included.Several clinical tests were performed: primary outcomes were the LM thickness from ultrasound measurements, trunk range of motion(ROM) from 3D kinematic tests, and median frequency and root mean square values of LM by electromyography measurements. The secondary outcomes Numeric Rating Scale for Pain(NRS) and the Oswestry Disability Index(ODI) were administered. Comparisons between groups were made with ANOVA, pvalues< 0.05, with Tukey’s HSD post-hoc test were considered significant.Results: A total of 161 participants were included, 50 healthy controls, 59 chronic LBP patients, and 52 subacute LBP patients. Trunk ROM and LM thickness were significantly larger in healthy controls compared to all LBP patients(p < 0.01). A lower LM thickness was found between subacute and chronic LBP patients although not significant(p = 0.11–0.97). All between-group comparisons showed no statistically significant differences in electromyography outcomes (p = 0.10–0.32). NRS showed no significant differences between LBP subgroups(p = 0.21). Chronic LBP patients showed a significant higher ODI score compared to subacute LBP patients(p = 0.03).Conclusions: Trunk ROM and LM thickness show differences between LBP patients and healthy controls.

The climate change and depletion of the world’s raw materials are commonly acknowledged as the biggest societal challenges. Decreasing the energy use and the related use of fossil fuels and fossil based materials is imperative for the future. Currently 40% of the total European energy consumption and about 45% of the CO2 emissions are related to building construction and utilization (EC, 2015). Almost half of this energy is embodied in materials. Developing sustainable materials to find replacement for traditional building materials is therefore an increasingly important issue. Mycelium biocomposites have a high potential to replace the traditional fossil based building materials. Mycelium is the ‘root network’ of mushrooms, which acts as a natural glue to bind biomass. Mycelium grows through the biomass, which functions simultaneously as a growth substrate and a biocomposite matrix. Different organic residual streams such as straw, sawdust or other agricultural waste can be used as substrate, therefore mycelium biocomposites are totally natural, non-toxic, biological materials which can be grown locally and can be composted after usage (Jones et al., 2018). In the “Building On Mycelium” project Avans University of Applied Sciences, HZ University of Applied Sciences, University of Utrecht and the industrial partners will investigate how the locally available organic waste streams can be used to produce mycelium biocomposites with properties, which make them suitable for the building industry. In this project the focus will be on studying the use of the biocomposite as raw materials for the manufacturing of furniture or interior panels (insulation or acoustic).
To decrease the environmental impact caused by the construction sector, biobased materials need to be further developed to allow better integration and acceptance in the market. Mycelium composites are innovative products, with intrinsic properties which rise the attention of architects, designers and industrial companies. Until now, research has focused on the mechanical properties of mycelium products. The aim has been improving their mechanical strength, to achieve wider application in the construction sector. Alongside this, to introduce mycelium composites to a wider market, the aesthetic experience of the public also needs to be considered. In the context of this proposal, it is argued that users of biobased products can shift their attitudes towards their surroundings by adjusting to the visual aesthetics within their environment or products they surround themselves with (Hekkert, 1997). This can be further attributed to colours which can be experienced as warm or cold, aggressive or inviting, leading to experiences that may include pleasure or displeasure indicating the future success of the bio based product. Mycelium composites can be used as building materials, but also as interior design materials, therefore visible to its user. It is to determine the appropriate methodologies to confer colour to mycelium composites that the companies Impershield and Dorable came together to form the consortium for the present project. The investigated ways are: 1. Through the preliminary colouring of fibres and their use as substrate for mycelium growth 2. The surface treatment of the final product. The Centre of Expertise BioBased Economy (CoEBBE) and the Centre of Applied Research for Art and Design (CARADT) will be guiding the research through their experience with mycelium composites. This project will lay the basis to enhance visual appearance of mycelium composites, with the utilization of natural pigments, natural paints and coatings.
Human kind has a major impact on the state of life on Earth, mainly caused by habitat destruction, fragmentation and pollution related to agricultural land use and industrialization. Biodiversity is dominated by insects (~50%). Insects are vital for ecosystems through ecosystem engineering and controlling properties, such as soil formation and nutrient cycling, pollination, and in food webs as prey or controlling predator or parasite. Reducing insect diversity reduces resilience of ecosystems and increases risks of non-performance in soil fertility, pollination and pest suppression. Insects are under threat. Worldwide 41 % of insect species are in decline, 33% species threatened with extinction, and a co-occurring insect biomass loss of 2.5% per year. In Germany, insect biomass in natural areas surrounded by agriculture was reduced by 76% in 27 years. Nature inclusive agriculture and agri-environmental schemes aim to mitigate these kinds of effects. Protection measures need success indicators. Insects are excellent for biodiversity assessments, even with small landscape adaptations. Measuring insect biodiversity however is not easy. We aim to use new automated recognition techniques by machine learning with neural networks, to produce algorithms for fast and insightful insect diversity indexes. Biodiversity can be measured by indicative species (groups). We use three groups: 1) Carabid beetles (are top predators); 2) Moths (relation with host plants); 3) Flying insects (multiple functions in ecosystems, e.g. parasitism). The project wants to design user-friendly farmer/citizen science biodiversity measurements with machine learning, and use these in comparative research in 3 real life cases as proof of concept: 1) effects of agriculture on insects in hedgerows, 2) effects of different commercial crop production systems on insects, 3) effects of flower richness in crops and grassland on insects, all measured with natural reference situations
