Sustainable future is impossible without well-functioning sustainable economy that is based on new energy system with renewable and new energy sources. The European Union has put incredible efforts to transform the European economy into a circular, energy efficient and climate-neutral that at the same time provides an optimal business environment for sustainable growth, job creation and innovation. As the European Union has committed to make Europe the world's first carbon neutral continent the question is what are the regional contributions to the achievement of this ambition and making the European economy more sustainable and climate-neutral? The round table, organised by the Jean Monnet Chair in Sustainable EU Economy, brings together experts, policy makers, and representatives from business and academia to discuss different regional initiatives aimed at making the regional economy more sustainable and climate-neutral, and will especially focus on one of the most successful collective efforts to develop a sustainable regional H2 economy in the Northern part of the Netherlands.

from the article: "Abstract: The oral mucosa is the first immune tissue that encounters allergens upon ingestion of food. We hypothesized that the bio-accessibility of allergens at this stage may be a key determinant for sensitization. Light roasted peanut flour was suspended at various pH in buffers mimicking saliva. Protein concentrations and allergens profiles were determined in the supernatants. Peanut protein solubility was poor in the pH range between 3 and 6, while at a low pH (1.5) and at moderately high pHs (>8), it increased. In the pH range of saliva, between 6.5 and 8.5, the allergens Ara h2 and Ara h6 were readily released, whereas Ara h1 and Ara h3 were poorly released. Increasing the pH from 6.5 to 8.5 slightly increased the release of Ara h1 and Ara h3, but the recovery remained low (approximately 20%) compared to that of Ara h2 and Ara h6 (approximately 100% and 65%, respectively). This remarkable difference in the extraction kinetics suggests that Ara h2 and Ara h6 are the first allergens an individual is exposed to upon ingestion of peanut-containing food. We conclude that the peanut allergens Ara h2 and Ara h6 are quickly bio-accessible in the mouth, potentially explaining their extraordinary allergenicity."

Overcoming Challenges in local green H2 economies Organizer: Dr Beata Kviatek, Jean Monnet Chair in Sustainable EU Economy, Centre of Expertise Energy / International Business School / Hanze University of Applied Sciences Groningen, the Netherlands One of the main pathways of the current energy transition includes development of regional green hydrogen economy, usually based in the so-called hydrogen valleys. The development of regional green hydrogen economies enables to green up regional industry and mobility, brings new business opportunities for local and regional businesses, redirects regional investments and financial streams, and proposes new avenues for regional education, knowledge, and research institutions. However, the complexity of regional transformation towards green hydrogen economy, poses challenges that require a close cooperation between different local and regional stakeholders at multiple levels, including national and European. What are these challenges in developing regional green hydrogen economies here, in the northern part of the Netherlands, and in other regions of Europe and what are the new pathways to overcome challenges in regional green hydrogen economies? – is the main question of the proposed panel discussion that will involve academics, policy makers, and practitioners from the northern part of the Netherlands as well as some European regions.

Hydrogen (H2) is a key element in the Dutch energy transition, considered a sources of flexibility to balance the variable renewable energy sources, facilitating its integration into the energy system. But also as an energy carrier. Both the gas and electricity transmission operators (TSO) have the vision to interconnect their networks with H2, by distributing the green H2 produced with offshore electrolysers into high pressure gas pipelines to relive the overload electric network. The planned compressed H2 pipelines cross the north of North-Holland region, offering a backbone for a H2 economy. Furthermore, at regional level there are already a big number of privet-public H2 developments, among them the DuWaAl, which is a H2 production-demand chain, consists of 1) An H2 mill, 2) 5 filling stations in the region and 3) a large fleet of trucks and other users. Because of these developments, the North-Holland region needs a better insight into the position that H2 could fulfil in the local energy system to contribute to the energy transition. The aim of this research is to analyse these H2 economy, from the emergent to settled, by identifying early and potential producer- consumer, considering the future infrastructure requirements, and exploring economy-environmental impacts of different supply paths

Author supplied from the article: Abstract A temperature compensated hydrogen sensor was designed and made capable of detecting H2 within a broad range of 100–10.000 ppm while compensating instantaneously for large (±25 °C) temperature variations. Two related operational constraints have been simultaneously addressed: (1) Selective, and sensitive detection under large temperature changes, (2) Fast warning at low and increasing H2 levels. Accurate measurements of hydrogen concentrations were enabled by matching relevant time-constants. This was achieved with a microchip having two temperature coupled palladium nanowires. One of the H2 sensitive Pd nanowires was directly exposed to hydrogen, whilst the other nanowire was used as a temperature sensor and as a reference. A drop forging technique was used to passivate the second Pd wire against H2 sensing. Temperature effects could be substantially reduced with a digital signal processing algorithm. Measurements were done in a test chamber, enabling the hydrogen concentration to be controlled over short and long periods. An early response for H2 sensing is attainable in the order of 600 milliseconds and an accurate value for the absolute hydrogen concentration can be obtained within 15 s.

BACKGROUND: Over 30 % of older patients experience hospitalization-associated disability (HAD) (i.e., loss of independence in Activities of Daily Living (ADLs)) after an acute hospitalization. Despite its high prevalence, the mechanisms that underlie HAD remain elusive. This paper describes the protocol for the Hospital-Associated Disability and impact on daily Life (Hospital-ADL) study, which aims to unravel the potential mechanisms behind HAD from admission to three months post-discharge.METHODS/DESIGN: The Hospital-ADL study is a multicenter, observational, prospective cohort study aiming to recruit 400 patients aged ≥70 years that are acutely hospitalized at departments of Internal Medicine, Cardiology or Geriatrics, involving six hospitals in the Netherlands. Eligible are patients hospitalized for at least 48 h, without major cognitive impairment (Mini Mental State Examination score ≥15), who have a life expectancy of more than three months, and without disablement in all six ADLs. The study will assess possible cognitive, behavioral, psychosocial, physical, and biological factors of HAD. Data will be collected through: 1] medical and demographical data; 2] personal interviews, which includes assessment of cognitive impairment, behavioral and psychosocial functioning, physical functioning, and health care utilization; 3] physical performance tests, which includes gait speed, hand grip strength, balance, bioelectrical impedance analysis (BIA), and an activity tracker (Fitbit Flex), and; 4] analyses of blood samples to assess inflammatory and metabolic markers. The primary endpoint is additional disabilities in ADLs three months post-hospital discharge compared to ADL function two weeks prior to hospital admission. Secondary outcomes are health care utilization, health-related quality of life (HRQoL), physical performance tests, and mortality. There will be at least five data collection points; within 48 h after admission (H1), at discharge (H3), and at one (P1; home visit), two (P2; by telephone) and three months (P3; home visit) post-discharge. If the patient is admitted for more than five days, additional measurements will be planned during hospitalization on Monday, Wednesday, and Friday (H2).DISCUSSION: The Hospital-ADL study will provide information on cognitive, behavioral, psychosocial, physical, and biological factors associated with HAD and will be collected during and following hospitalization. These data may inform new interventions to prevent or restore hospitalization-associated disability.
