Through historical and anthropological inquiry, this paper addresses the issue of memory antagonisms involving cultural landscapes in the context of a former mining region: the Belgian Black Country. This region, which became increasingly industrialized in the 19th century through the massive development of coal mining and steel industry, subsequently experienced deindustrialization, and now finds itself mobilized in a process of 'post-industrial' mutation. The paper is divided into two parts. In the first part, it examines how the landscapes inherited from industry, and in particular the slag heaps of the coalfield, have over time become repositories of a working-class memory, through the living and working practices of the communities surrounding the mines. It also documents the various representations attached to these landscape objects, whose contradictions echo the oppositions between capital and labor that have marked the development of industrial capitalism. The second part of the paper, which focuses on the present situation, examines how these representations are remobilized in the valorization processes that are initiated by different actors, in the context of a 'post-industrial' urban transition strategy that seeks to produce a unified and pacified historical narrative. We'll be looking at how historical conflicts still permeate the representations of these landscapes, the question of their conservation, and their possible future. [ABSTRACT FROM AUTHOR]

Human geographers have analyzed the co-constitutive relationship between race, gender and sexualities across different spaces and social contexts and have called for intersectional approaches in discussions of identities, power and space. This article applies an intersectional framework to the processes of sexualization, racialization and exoticization that shape the daily lives and erotic/romantic encounters experienced and narrated by participants to two different projects: gay and bisexual men from a North African background living in Belgium; Italian gay men living in England; non-White gay men living in Italy. By discussing qualitative data collected during interviews with these men, and through a continued dialogue about this data between the authors, the paper explores both the effects of these processes on the lives of participants, and the strategies they enact to navigate their social worlds. The focus is on two elements, central to participants' narratives: the specificity of the intersectional experience of encountering men who expect a specifically gendered and racialized performance based on 'roughness' and 'wildness', and the capitalization on these exoticizing and racializing images to increase one's desirability on the dating/hook-up scene and everyday social and work life. By highlighting these elements, this paper shows the importance of applying an intersectional approach to analyses of the entanglements of racialization and sexualization in order to complicate linear accounts of these processes.

Paperwork has always been a central part of bureaucratic work. Over the last few years, bureaucratic procedures have become increasingly standardised and digitalised. Based on interviews and ethnographic fieldwork within welfare offices in Switzerland and Belgium, we reflect on the way evidence is constructed within social policy and cases built for or against noncitizen welfare recipients in order to show how paper truths are established and challenged. The focus on digital practices within public policy implementation highlights how it contributes to enhanced control mechanisms on the implementation level and how migration law continues to guide welfare governance for noncitizens. This allows targeting of the most marginalised groups, whose rights to access state support are institutionally impeded. Through database information flows, official forms, paper reports and face-to-face meetings, we further show how a hybrid form of bureaucratic work emerges, where direct contact with the client is still key, yet highly influenced by standardisation processes.

Background: Augmented reality (AR) is receiving increasing interest as a tool to create an interactive and motivating learning environment. Yet, it is unclear how instructional support affects performance in AR. Objectives: This study sought to explore how varying the instructional support in AR can affect performance‐related behaviours of students with low cognitive abilities during assembly work. Methods: A total of 90 Belgian secondary school students repeatedly executed four different realistic assembly tasks. Three levels of instructional support (low, medium, and high) in AR as well as a control condition with paper instructions with a high level of detail were systematically varied across tasks and participants. Results and Conclusions: Multilevel regression analyses showed that AR instructions yielded lower assembly times and a lower perceived physical effort than paper instructions. Additionally, participants perceived tasks as less complex when given AR instructions with a high or a medium level of detail than when given a low level of detail. No effects of instructional support were established for other performance‐related behaviours, namely necessary assistance, error‐making, cognitive load, competence frustration, and stress. Effect sizes were small, at least among the instructional support conditions studied, yielding a limited base for adaptivity. Presumably, tailoring the instructional support in AR is only beneficial for highly complex tasks. The results might be useful for the design and implementation of AR in educational settings. Lay Description: What is currently known about the subject matter: Augmented reality is knowing increased use in education.Little is known about how to design effective instructional support in augmented reality. What this paper adds: This study represents an initial insight into how to personalize instructional support.The impact of instructional support on augmented reality performance of students with low cognitive abilities was investigated.The study suggests that varying instructional support may lead to differences in performance outcomes. Implications for practitioners: How instructional support is constructed may affect augmented reality learning.The results may inform the design of effective augmented reality learning environments for students with special needs.How individual, contextual, and task‐specific characteristics moderate the effectiveness of instructional support should be further investigated.

Background: The assessment of primary care organizations is considered to be essential for improving care. However, the assessments' acceptability to professionals poses a challenge. Developing assessment programmes in collaboration with the end-users is a strategy that is widely encouraged to make interventions better targeted. By doing so, it can help to prevent resistance and encourage adherence to the assessment. This process, however, is rarely reported. This paper aims to fill this gap by describing the process of the co-production of an assessment programme for community health centres (CHCs) affiliated to the Federation of Community Health Centres (FCHC) in French-speaking Belgium. Methods: We conducted a documentary study on the co-production of the assessment programme before carrying out semi-structured interviews with the stakeholders involved in its development. Results: CHCs in French-speaking Belgium are increasing in number and are becoming more diverse. For the FCHC, this growth and diversification pose challenges for the meaning of CHC (an identity challenge) and what beneficiaries can expect in terms of the quality of organizations declaring themselves CHC (a quality challenge). Faced with this double challenge, the FCHC decided to develop an assessment programme, initially called Label, using participatory action research. During the co-production process, this initial programme version was abandoned in favour of a new name "DEQuaP". This new name embodies new objectives and new design regarding the assessment programme. When studying the co-production process, we attributed these changes to two controversies. The first concerns how much and which type of variety is desired among CHCs part of the FCHC. The second concerns the organization of the FCHC in its capacity as a federation. It shed light on tensions between two professional segments that, in this paper, we called "political professionalism" and "pragmatic professionalism". Conclusions: These controversies show the importance of underlying challenges behind the development of an assessment programme for CHCs. This provided information about the evolution of the identity of multidisciplinary organizations in primary care. Issues raised in the development of this assessment programme also show the importance of considering assessment methods that reflect and embody the current realities of these organizations and the way of developing these assessment methods.

The REpowerEU plan prioritizes combining electrification with low-carbon hydrogen for a green energy shift. However, uncertainties surrounding the future hydrogen market and its supply costs impede the establishment of its value chain. Without definite plans for hydrogen production and infrastructure, investing in low-carbon hydrogen industrial processes is risky. Simultaneously, the absence of solid market interest poses challenges in deploying a hydrogen backbone. In recent years, European gas Transmission System Operators (TSOs) in Belgium, Netherlands, and Germany, have introduced various roadmaps for their prospective national hydrogen network. Despite the infrastructure proposals, detailed quantitative scenario analysis for the future hydrogen supply chain is still missing. This paper presents a hydrogen infrastructure model that employs Mixed Integer Linear Programming (MILP) for investment and operational cost optimization at detailed spatiotemporal resolution. A regionalization method is proposed to allocate the potential hydrogen consumption in different industrial sectors across various clusters within a country, represented as the prospective hydrogen demand nodes. The model assesses extreme supply scenarios to examine the robustness of the resulting network infrastructure and compare the system-levelized cost of hydrogen. A real-life case study focusing on the potential Belgian hydrogen supply chain showcases the model's capabilities and outputs. • Regionalization of the industrial hydrogen consumption derived from a national-scale energy system model. • MILP cost optimization model for hydrogen infrastructure design. • Comparative analysis of diverse extreme low-carbon hydrogen supply scenarios. • In-depth case study focusing on the prospective Belgian hydrogen backbone.

In phosphorites, the content and distribution of rare earth elements are linked to the environment of phosphogenesis. This paper focuses on the question of sources and processes controlling the rare earth element content of apatite from Belgian phosphorites formed during three major phosphogenic events in the Lower Palaeozoic, Late Cretaceous and Cenozoic. To constrain sources and processes, new data include petrological, mineralogical (including cathodoluminescence and Raman spectroscopy) and in situ trace element and Sr and O isotope analyses of apatite. Fluorapatite from Lower Palaeozoic P‐rich conglomerates has the greatest rare earth element enrichment. It is affected by metamorphism that led to deformation of apatite nodules and formation of garnet porphyroblast inclusions. The role of Fe‐oxyhydroxides in element scavenging is highlighted by some apatite nodules that maintain their primary middle rare earth element enrichment, while others are characterized by altered rare earth element patterns resulting from competition for these elements between co‐crystallizing minerals during deformation. A systematic shift towards lower δ18O and radiogenic Sr isotopic composition compared to contemporaneous seawater indicate interaction with 18O‐depleted meteoric fluids and a crustal component. By contrast, carbonate‐rich fluorapatite from the Late Cretaceous phosphatic chalk mostly keeps its primary trace element and isotopic signatures (close to seawater), although an external rare earth element addition is noted, as well as rare earth element redistribution induced by diagenetic alteration. Cenozoic carbonate fluorapatite nodules mostly present flat rare earth element patterns that are indicative of a detrital influence. Slight changes in rare earth element distribution are assigned to post‐depositional alteration, which also led to an increase in radiogenic Sr, with unchanged δ18O compared to seawater. The methodology followed here efficiently helps in deciphering the processes that modified the chemistry of apatite in the frame of major phosphogenic events. [ABSTRACT FROM AUTHOR]

Background: The COVID-19 pandemic immensely impacted care provision, including quality of care in general practice. This paper aimed: (1) to assess how Belgian general practices acted upon the six dimensions of quality of care during COVID-19; (2) to study differences between the three Belgian regions; and (3) to benchmark the performance of the Belgian practices against the performance in other European countries. Methods: The data collected from 479 Belgian practices during 2020–2021 using an online survey as part of the international cross-sectional PRICOV-19 study were analyzed. Hereby, descriptive statistics, chi-squared tests, and binary logistic regression analyses were performed. Thirty-four survey questions related to the six dimensions of quality of care were selected as outcome variables. The adjusted regression models included four practice characteristics as covariates: practice type, being a teaching practice for GP trainees, multidisciplinarity of the team, and payment system. Results: Belgian practices made important organizational changes to deliver high-quality care during COVID-19. Most practices (n = 259; 56.1%) actively reached out to vulnerable patients. Limitations to the practice building or infrastructure threatened high-quality care in 266 practices (55.5%). Infection prevention measures could not always be implemented during COVID-19, such as using a cleaning protocol (n = 265; 57.2%) and providing a separate doctor bag for infection-related home visits (n = 130; 27.9%). Three hundred and sixty practices (82.0%) reported at least one safety incident related to a delayed care process in patients with an urgent condition. The adjusted regression analysis showed limited significant differences between the Belgian regions regarding the quality of care delivered. Belgian practices demonstrated varied performance compared to other European countries. For example, they excelled in always checking the feasibility of isolation at home but reported more patient safety incidents related to timely care than at least three-quarters of the other European countries. Conclusions: Future studies using different design methods are crucial to investigate which country and practice characteristics are associated with delivering high-quality care.

This paper describes the process of developing classroom culture that promotes reciprocal intercultural encountering in the primary school. Storycrafting, an oral storytelling method used for democratic encounters between participants, was used to connect classes in Scotland, Finland and Belgium over three cycles of design-based research. Abductive analysis produced a theoretical framework of seven key dimensions that influence the learning space for reciprocal encounters: power, knowledge, relatedness, purpose, structure, continuity and meaningfulness. These dimensions were used to identify four kinds of learning spaces that occurred during the implementation of the story exchange: the ambivalent space, the space of information, the transitional space and the space of reciprocal encountering. The intervention created a platform for children's encounters that reinforced mutuality and reciprocal interactions rather than Othering the exchange partners. [ABSTRACT FROM AUTHOR]

There has been a growing policy interest in establishing connections between heritage and education. Nevertheless, there seems to be very little evaluation or critical reflection on what actually happens in practice, and it remains unclear how heritage education is employed in countries throughout Europe. The aim of this paper is to assess the current status of heritage education in Flanders (the Dutch-speaking northern part of Belgium) via a literature review and an exploratory case study. The perceptions and opinions of pre-service teachers (n = 17) were investigated using three instruments: a questionnaire, document analysis, and the think aloud method. The results show that the pre-service teachers had a traditional interpretation of heritage, mainly relying on well-known and monumental examples and following a rather historical–artistic conception. However, it was found that their opinions were positive towards the use of heritage as an educational resource, and their evaluations of educational materials from the heritage and museum sector provided detailed information concerning teachers' desires and needs in this regard. The implications of this study should encourage initial teacher training in Flanders to further consider the epistemological and methodological challenges in the emerging field of heritage education.

Background: The Bethesda System for Reporting Thyroid Cytopathology is a commonly used classification for fine needle aspiration (FNA) cytology of suspicious thyroid nodules. The risk of malignancy (ROM) for each category has recently been analyzed in three international databases. This paper compares the diagnostic performance of the Bethesda classification in a high‐volume referral center in Belgium. Methods: All consecutive thyroid procedures were registered in a prospective database from January 2010 till August 2022. Patient and surgical characteristics, preoperative Bethesda categories, and postoperative pathology results were analyzed. Results: Out of 2219 consecutive thyroid procedures, 1226 patients underwent preoperative FNA. Papillary thyroid cancer was the most prevalent malignancy (N = 119, 70.4%), followed by follicular (N = 17, 10.1%) and medullary thyroid cancer (N = 15, 8.9%). Micropapillary thyroid cancer was incidentally found in 46 (3.8%) patients. Bethesda categories I, II, III, IV, V, and VI, respectively, represented 250 (20.4%; ROM 4.4%), 546 (44.5%; ROM 3.8%), 96 (7.8%; ROM 20.8%), 231 (18.8%; ROM 15.2%), 62 (5.1%; ROM 72.6%), and 41 (3.3%; ROM 90.2%) patients. Overall ROM was 13.8%. An negative predictive value (NPV) of 96.2% was found. Overall specificity was 64.2% with a positive predictive value (PPV) of 31.9%. Diagnostic accuracy was 67.8%. Compared to international databases (CESQIP, EUROCRINE, and UKRETS), ROM in this study appeared lower for Bethesda category IV (15.2 vs. 26.7% and p = 0.612). Conclusion: Despite being validated in numerous studies, ROM based on preoperative FNA cytology classified according to the Bethesda classification may vary among surgical centers and countries as this study reveals a higher NPV and lower PPV.

This paper describes a multi‐family therapy (MFT) group for adult outpatients with obsessive‐compulsive disorder and their family members. Since family accommodation (FA) is known to maintain OCD symptoms by preventing exposure and response prevention (ERP), reduction of FA is a major focus of the treatment. Furthermore, psychoeducation, conjoint ERP and (re)discovering resources and strengths of families are also important therapeutic foci of the family group. The organisation of MFT is explained and involvement of family is illustrated with clinical vignettes. Finally, some reflections about MFT are provided. On the basis of initial clinical impressions, MFT seems a promising approach. A clinical trial is currently underway. [ABSTRACT FROM AUTHOR]

This paper introduces a Techno-Economic Assessment (TEA) on present and future scenarios of different energy storage technologies comprising hydrogen and batteries: Battery Energy Storage System (BESS), Hydrogen Energy Storage System (H 2 ESS), and Hybrid Energy Storage System (HESS). These three configurations were assessed for different time horizons: 2019, 2022 and 2030, under both on-grid and off-grid conditions. For 2030, a sensitivity analysis under different energy scenarios was performed, covering other trends in on-grid electric consumption and prices, CO 2 taxation and the evolution of hydrogen technology prices from 2019 until 2030. The selected case study is the Research Park Zellik (RPZ), a CO 2 -neutral sustainable Local Energy Community (LEC) in Zellik, Belgium. The software HOMER (Hybrid Optimisation Model for Electric Renewable) has been selected to design, model and optimise the defined case study. The results showed that BESS was the most competitive when the electric grid was available among the three possible storage options. Additionally, HESS was overall more competitive than H 2 ESS-only, regardless of the grid connection mode. Finally, as per HESS, hydrogen was proved to play a complementary role when combined with batteries, enhancing the flexibility of the microgrid and enabling deeper decarbonisation by reducing the electricity bought from the grid, increasing renewable energy production and balancing toward an island operating mode. • Assessment of hybrid energy storage systems for future energy scenarios. • Sensitivity analysis with different technical, economic, and environmental KPIs. • Analysis of the effects of the connection and capacity access to the electric grid. • Application to a real case study: a CO2-neutral Local Energy Community.

Thermal processes represent a significant fraction of industrial energy consumptions, and they rely mainly on fossil fuels. Thanks to technological innovation, highly efficient devices such as high-temperature heat pumps are becoming a promising solution for the electrification of industrial heat. These technologies allow for recovering waste heat sources and upgrading them at temperatures up to 200 °C. Moreover, the coupling of these devices with thermal storage units can unlock the flexibility potential deriving from the industrial sector electrification by means of Demand-Side Management strategies. The aim of this paper is to quantify the impact on the energy system due to the integration of industrial high-temperature heat pumps and thermal storage units by means of a detailed demand–supply model. To do that, the industrial heat demand is investigated through a set of thermal process archetypes. High-temperature heat pumps and thermal storage units for industrial use are included in the open-source unit commitment and optimal dispatch model Dispa-SET used for the representation of the energy system. The case study analyzed is Belgium, and the analysis is performed for different renewable penetration scenarios in 2040 and 2050. The results demonstrate the importance of a proper sizing of the heat pump and thermal storage capacity. Furthermore, it is obtained that the electrification of the thermal demand of industrial processes improves the environmental impact (84% reduction in CO2 emissions), but the positive effect of the energy flexibility provided by the heat pumps is appreciated only in the presence of a very high penetration of renewable energy sources.

Introduction: Non-communicable diseases, such as arterial hypertension (HTN) and type-2 diabetes (T2D), pose a global public health problem. Integrated care with focus on person-centred principles aims to enhance healthcare quality and access. Previous qualitative research has identified facilitators and barriers for scaling-up integrated care, however the lack of standardized terms and measures hinder cross-country comparisons. This paper addresses these gaps by presenting a generic codebook for qualitative research on integrated care implementation for HTN and T2D. Description: The codebook serves as a tool for deductive or deductive-inductive qualitative analysis, organizing concepts and themes from qualitative data. It consists of nine first level and 39 second level themes. First level codes cover core issues; and second level codes provide detailed insights into facilitators and barriers. Discussion: This codebook is more widely applicable than previously developed tools because it includes a broader scope of stakeholders across micro, meso, and macro levels, and the themes being derived from highly diverse health systems across highand low-income countries. Conclusion: The codebook is a useful tool for implementation research on integrated care for HTN and T2D at global scale. It facilitates cross-country learning, contributing to improved implementation, scale-up and outcomes. [ABSTRACT FROM AUTHOR]

Research on the electoral personalization of politics has stressed a trend towards a greater role of top prominent political figures (party leaders and ministers). This trend was described as centralized electoral personalization. Yet, this trend is merely one side of a more complex story. No leader attracts all voters' support, and other candidates manage to stand out despite lower resources and visibility. Using a unique dataset of 47,239 actual ballot papers cast for the 2018 Belgian local elections, we show that candidate-level, list-level and district-level factors result in distinct preference voting behaviour. While these factors lead to unmistakable forms of (de-)centralized personalized forms of elections, we furthermore, show that intermediary situations distinctively emerge. A significant number of 'subtop' candidates stand out among candidates, by attracting support from voters who do not support the mere leader of the list. This 'oligarchized personalization' would deserve greater attention in the literature. [ABSTRACT FROM AUTHOR]

Recent climate activism has played a key role in denouncing the unsustainability of representative democracy. Previous research has investigated the attitudes of climate activists towards representative institutions along the conceptual distinction between 'environmental' and 'ecological' democracy. Yet, little attention has been paid to climate activists' critique of capitalism and how it relates to demands for democratic reform. Our paper addresses this gap by conducting a mixed-method analysis of protest survey data collected in Belgium in 2019. Our findings show that activists display low levels of trust towards representative institutions, but still abide by the ideals of environmental democracy within the boundaries of existing institutions. At the same time, we observe a widespread critique of capitalism, signaling attraction towards the ideals of ecological democracy. Overall, our findings challenge the binary distinction between environmental versus ecological democracy, and raises normative questions about the role of environmental social movements in economic and democratic reform.

Although people with a migration background (MB) have more unmet mental health needs than the general population, patients with a MB are still underrepresented in mental health care services. Provider bias towards these patients has been evidenced repeatedly but its driving factors remain elusive. We assessed the moderating effect of the individual (e.g. age and ethnicity), interpersonal (e.g. healthcare provider trust), and organisational (e.g. perceived workload) factors on general practitioners (GPs) differential decision-making regarding diagnosis, treatment, and referral for a depressed patient with or without a MB. An experimental study was carried out in which GPs were shown one of two video vignettes featuring adult male depressed patients, one with a MB and the other without. Belgian GPs (n = 797, response rate was 13%) had to decide on their diagnosis, treatment, and referral. Analysis of variance and logistic regression were used to analyse the effect of a MB, adding interaction terms for the explanatory variables. Overall, we found that there were ethnic differences in GPs' decisions regarding diagnosis and treatment recommendations. GPs perceived the symptoms of the patient with a MB as less severe (F = 7.68, p < 0.01) and demonstrated a reduced likelihood to prescribe a combination of medical and non-medical treatments (F = 11.55, p < 0.001). Those differences increased in accordance with the GP's age and perceived workload; at an interpersonal level, we found that differences increased when the GP thought the patient was exaggerating his distress. This paper showed that lower levels of trust among GPs' towards their migrant patients and high GP workloads contribute to an increased ethnic bias in medical decision-making. This may perpetuate ethnic inequalities in mental health care. Future researchers should develop an intervention to decrease the ethnic inequities in mental health care by addressing GPs' trust in their migrant and ethnic minority patients.

This paper is the first to calculate welfare, measured by the Index of Sustainable Economic Welfare (ISEW), for the EU-15 countries in a standardized and comparable way. This paper does so by building on a case study for Belgium by Van der Slycken and Bleys (2023) that puts forward a "2.0 methodology" with two distinct ISEWs that deal with cross-time and cross-boundary issues. Both welfare and GDP per capita improved in the EU-15 between 1995 and 2018. Yet, there is an important divergence between welfare and GDP: over time experiential welfare per capita and the per capita benefits and costs of present activities improved by respectively 10,5% and 13,4%, which is less than one third and half of the growth in GDP per capita that grew by 32,4%. These welfare trends are mainly driven by individual consumption growth, the shadow economy and welfare losses from income inequality, which compensated about half of the welfare gains of the former two categories. The gap between welfare and GDP diverged especially after the financial crisis when welfare started stagnating. At the end of the studied period, the EU-15 had already recovered from the financial crisis from a GDP perspective, but not from a welfare view. Since welfare in 2018 was less than 2% lower than the period-maximum, there is no conclusive evidence in favor of the threshold hypothesis at the level of the EU-15. However, the fact that welfare levels in nine countries are more than 5% lower than their peak values signals a clear threshold for these countries. Yet, welfare can be increased beyond previous peaks with postgrowth policies that focus on social and ecological welfare. • Two variants of the Index of Sustainable Economic Welfare with distinct time and boundary choices are compiled for the EU-15. • From 1995 to 2018, GDP per capita grew by 32,4% while welfare per capita only increased by 10,5% and 13,4%. • Welfare and GDP increasingly diverged, especially after the financial crisis when welfare started stagnating. • By 2018, the EU-15 had already recovered from the financial crisis from a GDP perspective, but not from a welfare view. • A majority of the EU-15 countries has a clear welfare threshold point with 2018-values being lower than period maxima.

Droughts are the most expensive climate disasters as they leave long-term and chronic impacts on the ecosystem, agriculture, and human society. The intensity, frequency, and duration of drought events have increased over the years and are expected to worsen in the future on a regional and planetary/global scale. Nature-based solutions (NBS) such as wetland and floodplain restorations, green infrastructures, rainwater harvesting, etc., are highlighted as effective solutions to cope with the future impacts of these events. While the role of NBS in coping with the impacts of other disasters, such as floods, has been extensively studied, there has been a lack of comprehensive review of NBS targeting drought. The following paper provides a unique critical state-of-the-art literature review of individual drought-related NBS around the world, in Europe, and particularly in Belgium, and assesses the critical differences between the NBS applied globally and in Flanders. An extensive literature review was conducted to systematically analyze NBS, listing the type, the location, the status of the implementation, and the possible recommendations proposed to optimize future NBS applications. Finally, a comparison is made between small- and large-scale applications of NBS. By analyzing all these aspects, especially the level of effectiveness and recommendations, insight was gained into the future potential of NBS and possible improvements. The research indicated a lack of scientific publications, especially in Belgium. Hence, grey literature was also included in the literature review. Only four papers included a quantitative assessment regarding the effectiveness of drought on a global level, all stating a positive impact on groundwater recharge. In contrast, at regional and country levels, the performance of NBS was not quantified. The number of large-scale implementations is low, where landscape- or watershed-scale holistic approaches to drought mitigation are still scarce. Some successfully implemented projects are only very local and have a long realization time, two aspects that limit achieving visible impact at a larger scale. Among the many NBS, wetlands are recognized as highly effective in coping with drought but are still degraded or lost despite their significant restoration potential. A common effectiveness evaluation framework shall be followed, which gives policymakers a clear view of the different NBS investment options. Furthermore, a more collaborative approach is recommended globally, including different stakeholder groups, with specific attention to the local communities. To conclude, future research should increase the evidence base and implementation of drought-mitigating NBS. • Drought-mitigating Nature-Based Solutions (NBS) are systematically reviewed. • Few NBS studies focus on drought compared to other hazards such as floods. • Most NBS implementations are located in Europe. • Effectiveness is not well quantified for implemented NBS. • For achieving considerable drought mitigation, large-scale NBS are needed.

Belgium is known for its traditional lambic beer productions, obtained through spontaneous fermentation and maturation in wooden barrels. Lambic beer is also used to make fruit lambic beers, such as Kriek beer. Despite fruit beer being an old beer type, dating back to the second half of the seventeenth century, no research has been performed on lambic beer-fruit co-fermentation processes. Further, these beers get competition from market-driven, sweet, (fruit-)flavored ones without the co-fermentation step. This paper will first discuss a new, general fruit beer classification, going from sour fruit beers produced through co-fermentation to sweet ones without a co-fermentation step. Second, a state-of-the-art of the scarce literature on the microbiology and metabolomics of lambic beer-fruit co-fermentation processes will be given. [Display omitted] • The extended beer classification system encompasses a wide variety of beers. • New beer types with unconventional ingredients necessitate definition/classification. • The fruit beer classification facilitates discernment between sour and sweet beers. • A fruit beer co-fermentation step differentiates nonsweet and sweet fruit beers. • Scarce literature on fruit beers necessitates additional research.

Achieving carbon neutrality is probably one of the most important challenges of the 21st century for our societies. Part of the solution to this challenge is to leverage renewable energies. However, these energy sources are often located far away from places that need the energy, and their availability is intermittent, which makes them challenging to work with. In this paper, we build upon the concept of Remote Renewable Energy Hubs (RREHs), which are hubs located at remote places with abundant renewable energy sources whose purpose is to produce carbon-neutral synthetic fuels. More precisely, we model and study the Energy Supply Chain (ESC) that would be required to provide a constant source of carbon-neutral synthetic methane, also called e-NG (electric Natural Gas) or e-methane (electric methane), in Belgium from an RREH located in Morocco. To be carbon neutral, a synthetic fuel has to be produced from existing carbon dioxide (CO 2) that needs to be captured using either Direct Air Capture (DAC) or Post Combustion Carbon Capture (PCCC). In this work, we detail the impact of three different carbon sourcing configurations on the price of the e-methane delivered in Belgium. Our results show that sourcing CO 2 through a combination of DAC and PCCC is more cost-effective, resulting in a cost of 146 €/MWh for e-methane delivered in Belgium, as opposed to relying solely on DAC, which leads to a cost of 158 €/MWh. Moreover, these scenarios are compared to a scenario where CO 2 is captured in Morocco from a CO 2 emitting asset that allow to deliver e-methane for a cost of 136 €/MWh. • Model energy supply chain from Morocco to Belgium for electric methane; • Explore three CO2 sources for electric methane synthesis; • Analyse the pros and cons of each CO2 source on price and energy efficiency.

Due to the imperative nature of addressing climate change, the energy transition is currently underway, prompting the recognition of its urgency. Energy system optimisation models have emerged as crucial tools to assist policymakers in formulating laws and regulations that facilitate the transition towards carbon neutrality. While numerous models have been developed to explore various scenarios and define long-term objectives, only a few models focus on optimising the specific pathway to achieve these objectives. Many existing models lack the necessary time resolution to capture the integration of intermittent renewable energies; or are not open-source, creating a challenge in terms of transparency and reproducibility. This paper introduces EnergyScope Pathway, an open-source and documented model that addresses these limitations. It specifically optimises investment strategies for the whole-energy system over a 30-year period, or more, and optimising its hourly operation. This approach allows for a comprehensive evaluation of the effective integration of intermittent renewable energy sources. The model has a concise and efficient formulation, enabling its execution on personal laptops within approximately 15 min. By applying the model to the case study of Belgium, which presents challenges due to limited potential for renewable energy, we illustrate the importance of four pillars: energy efficiency, renewable energies, sector coupling, electrification and imports. The result pave the way to a new and incremental tool to support decision makers. In comparison to non open-source models, we verified the model's results with similar studies and found consistency in terms of technico-economic estimations. • Linear formulation of an optimisation model to represent a whole energy system transition pathway with an hourly resolution. • Short computational time, 15 min on a personal laptop • Quantify the pillars of the transition: efficiency, renewable energies and sector coupling. • Offers a new and incremental tool to support decision-makers in the energy transition. • Comparison of different approach to represent the transition.

The environmental and climatic conditions of the Late Pleistocene of Southern Belgium are here determined for the final part of Marine Isotope Stage 3 (MIS 3) and for MIS 2 on the basis of a study of rodent assemblages. This paper provides a synthesis of several sets of environmental and climatic data from Late Pleistocene sites, all of which are located in southern Belgium. One has previously been published (Caverne Marie-Jeanne), and seven are unpublished (Cavernes de Goyet, Trou des Nutons, Trou du Frontal, Trou de Chaleux, Grotte la Chefalize, Trou du Chêne, and Trou du Sureau). The habitat weighting and quantified ecology methods are applied to rodent material housed in the Royal Belgian Institute of Natural Sciences (RBINS, Brussels), and previous radiocarbon dates are updated, in order to reconstruct past environments. Among all the sites under analysis, the quantified ecology method shows that Trou de Chaleux corresponds to the coldest temperatures and lowest precipitation. Trou de Chaleux, with a chronology between ca. 15,964–14,014 cal yr B.P., could probably be placed in Greenland Stadial 2 (GS2) or Heinrich Event 1 (HE1). It has a rodent assemblage associated with a predominance of open dry and rocky formations, the most abundant species being the collared lemming and the narrow-headed vole. These data are found to coincide with previous studies carried out on the large-mammal, herpetofaunal, and avifaunal associations of the site, as well as on small-mammal associations from other sites in southern Belgium with similar chronology, such as Grotte Walou. Taken together, this indicates that these latest Pleistocene intervals in southern Belgium were characterized by harsh climatic and environmental conditions. In contrast, the other assemblages under study yielded much more heterogeneous results, frequently inconsistent with an attribution to the Pleistocene. This is likely to be a result of their admixture with Holocene material due to recent intrusions. • Manuscript provides an environmentally synthesis of eight Belgian Late Pleistocene sites. • Rodent's assemblages are used to reconstruct Late Pleistocene environment and climate. • 14C dating from the analysed sites have been calibrated in other to update them. • Heinrich Event 1 has been identified with the rodent's assemblage of Trou de Chaleux. • Rodent's data fits the previous published macromammals, herpetofauna and avifauna.

Power-to-gas facilities consume surplus renewable electricity generation to produce alternative gases, such as green hydrogen. They can be injected into, and transported by the gas network for further use, which is a promising way toward a low-carbon energy system. However, injecting alternative gases into the gas systems can adversely affect the gas composition and the lifespan of components (e.g., gas pipelines), and may threaten the reliability of the entire integrated electricity and gas systems (IEGS) in the long term. To address this issue, this paper proposes a long-term reliability evaluation method for IEGS with distributed hydrogen injections. First, new reliability indices are proposed to evaluate both gas adequacy and gas interchangeability under uncertainties. Then, a multi-state reliability model of the pipeline is developed to characterize the corrosion evolution and hydrogen embrittlement in the long term. A contingency management scheme (CMS) is devised to minimize load curtailments and gas interchangeability deviations under component failures. Moreover, several reformulation techniques are tailored to convexify the original two-stage mixed-integer nonlinear CMS optimization problem. An analytical reliability evaluation method embedded with a system state reduction technique is designed to evaluate the long-term reliability of the IEGS more efficiently. Finally, the IEEE 24 bus Reliability Test System and the practical Belgium gas system are used to validate the proposed method. The numerical results show that the injection of alternative gas could jeopardize the reliability of the studied IEGS by 39.73% in the long term. However, we have observed a critical time window (the 8th–9th year), in which if we conduct the inline inspection and maintenance more frequently, the reliability could be improved by up to 53.31%. These results suggest that the injection of alternative gas is beneficial, but should be carefully regulated to maintain the reliability of IEGS. • Impacts of hydrogen injections on long-term reliability of energy system. • Novel reliability indices to measure the expected gas quality under uncertainties. • Efficient reliability models of system components considering hydrogen injections. • Contingency regulation with varying gas compositions. • A fast analytical reliability evaluation method embedded with scenario reduction techniques.

This paper describes the drone-borne dosimetry performed in two separate case studies. Two drone measurements were performed using a reference dose-rate detector measuring the ambient dose equivalent rate. A first flight was used to obtain reference measurements using a cesium-137 point source and flying at multiple speeds and different heights. A second flight was performed above the D1 radium storage of Umicore in Olen, Belgium. The main goal of this flight was to perform a scanning pattern over the area to create a dose-rate map. After the flights, we used historic measurements and a dose-rate model verified by Monte Carlo simulations using Penelope (2018) to verify the dose-rates measurements performed by the drone. Finally, we used the findings from both flights to provide recommendations regarding drone measurements using dose-rate detectors. • Dose-rate detector time constants should be kept at a minimum. • Flight altitude should be as low as safely possible. • Flight speeds should be as low as battery capacity permits.

Design and safety assessments of geological disposals of heat-emitting radioactive waste require accurate evaluation of the thermal conductivity of the host medium. This paper presents a new approach to evaluate the anisotropic thermal conductivity of Boom Clay, a clayey layer that is studied as a potential host medium in Belgium by ONDRAF/NIRAS. The present approach is based on an inverse analysis of two in situ heater tests (the small-scale ATLAS IV Heater test and the large-scale PRACLAY Heater test) carried out in the HADES underground research facility (URF). The inverse analysis is performed by using the absolute error function and tolerant error-based method based on temperatures measured from 60 sensors across the two tests (i.e., from 29 sensors during the 900-day heating and cooling phase in the ATLAS IV Heater test and from 31 sensors during the nearly 7-year heating phase in the PRACLAY Heater test). In addition, thousands of numerical modeling cases are applied for both tests. The objective is to estimate a reasonable range of thermal conductivity variation that is characteristic of the entire host clay. Finally, a thermal conductivity range (λ h , λ v) = (1.55–1.95, 1.10–1.25) W/(m⋅K) is identified for the Boom Clay. [ABSTRACT FROM AUTHOR]
