ABSTRATC: In contrast to the increasing aquaculture production of mussels worldwide, production in the European Union (EU) has shown a decreasing trend over the last two decades. Aquaculture production of mussels in the EU peaked in the late 1990s at more than 600 000 tonnes; by 2016, production volume had dropped by 20% to 480 000 tonnes. As mussel production represents more than 1/3 of EU aquaculture production, this decrease is an important contributor to the stagnation of EU aquaculture. Previous studies have suggested diseases, lack of mussel seed (spat), and low profitability as the main causes of the EU mussel production decrease. In this study, we investigate how economic and environmental factors have contributed. Moreover, we examine if the different mussel production techniques (raft, longline, on-bottom, and "bouchot") have been differently affected, by analysing the economic performance and cost structure evolution for the period 2010-2016. We complement these results with a SWOT (strengths, weaknesses, opportunities, and threats) analysis of the EU mussel sector based on expert knowledge.

The overall objectives of meat inspection are to contribute to food safety, animal welfare, and animal health. In the European Union (EU), there is a request for a modernised meat inspection system that addresses these objectives in a more valid, feasible and cost-effective way than does the traditional system. One part of the modernisation deals with the coding system to register meat inspection findings. Although unified standards are set at the EU level for judgement criteria regarding fitness of meat for consumption, different national systems are in force. The question is the extent of the differences and whether there is a basis for harmonisation. To investigate this, information was gathered about the code systems in Denmark, Finland, Germany, Italy, Norway, Portugal and Spain. Moreover, meat inspection data covering pigs slaughtered in 2019 were collected. A comparison of the number of codes available, the terminology and the frequencies of the findings registered was undertaken. Codes with a similar meaning were grouped. Hereby, two lists were compiled showing the most common codes leading to total and to partial condemnation. Substantial variations in the percentage of condemned pigs and in the terms used were identified, and possible reasons behind this are discussed. Moreover, a strengths-weaknesses-opportunities-threats (SWOT)-like analysis was applied to the coding systems. Finally, the reasons for unfitness of meat given in the EU Food Inspection Regulation 2019/627 were compared to the national code lists. The results show the systems in force varied substantially, and each system had its advantages and disadvantages. The diverse terminology observed made it a challenge to compare data between countries. Development of harmonised terminology for meat inspection findings is suggested, enabling comparison of data between abattoirs, regions, and countries, while respecting the national epidemiological situation, the local food safety culture, and the trade agreements in force. ; Peer reviewed
In its 2009 decision in Infopaq (C-5/08), the Court of Justice of the European Union (CJEU) achieved a landmark result: the de facto, horizontal harmonization of the originality requirement. After that, nothing could stay the same. After providing an overview of the harmonization process in the copyright field over the past 30 years or so and, with that, the environment in which Infopaq came to be, this chapter considers Infopaq and the expansive effect of subsequent case law on other copyright subsistence requirements. The analysis also notes how the eventual outcome of Cofemel (C-683/17), insofar as works of applied art are concerned, is perfectly in line with such a jurisprudence. The chapter further considers the legal and institutional difficulties that such a string of CJEU decisions has given rise to and is yet to resolve before concluding that further questions are likely to be posed to the CJEU in the not too distant future. In other words: the construction of EU copyright is far from over.
The work needed to mechanically drive molten metal into a porous solid preform when producing a composite material by infiltration can significantly exceed the energy change required for thermodynamically reversible infiltration. We measure, by quantitative metallographic analysis of partially infiltrated, particle- or fiber-based non-metallic preforms, the evolution with saturation of the three interfaces present during the process. Results show that irreversible energy losses in the infiltration of alumina preforms by molten copper, aluminium or aluminium-tin alloy cannot be ascribed to the creation of liquid meniscus surface area at intermediate metal saturation. This result agrees with similar observations in soil science and gives experimental confirmation of predictions from a recent simulation of capillarity-dominated metal infiltration [Acta Mater., vol. 210, 2021, 116831]. ; This work was chiefly sponsored by the Swiss National Science Foundation (FNS), Project No. 200021 149899.

The Polish energy market heavily relies on coal. Pressured by the European Union, the Polish government has recently decided to accelerate coal phase-out and to gradually shut down all coal mines by 2049. In that context, it is necessary to assess the Polish energy market's state regarding energy efficiency, especially in the building stock. This paper aims to provide an overview of the current state of energy efficiency of residential buildings in Poland and insights into its future trends. A literature review was conducted, accompanied by focus group discussions with Polish building energy efficiency experts. The Polish energy sector is under a remarkable transformation that may be going too fast. A large gap between expectations, practices, and requirements can be observed. Raising awareness and capacity building in the energy efficiency sector, and a set of accessible guidelines should be developed so that the transformation is implemented correctly. A SWOT analysis results define the key opportunities and threats that are critical to meet net-zero emissions goals. The paper provides findings and insights on the 2020 targets status quo and raises awareness among stakeholders and fills a knowledge gap regarding energy efficiency in the Polish residential building stock. ; Peer reviewed
In September 2015, the Volkswagen Group (VW) admitted the use of 'defeat devices' designed to lower emissions measured during VW vehicle testing for regulatory purposes. Globally, 11 million cars sold between 2008 and 2015 are affected, including about 2.6 million in Germany. On-road emissions tests have yielded mean on-road NO[subscript x] emissions for these cars of 0.85 g km[superscript −1], over four times the applicable European limit of 0.18 g km[superscript −1]. This study estimates the human health impacts and costs associated with excess emissions from VW cars driven in Germany. A distribution of on-road emissions factors is derived from existing measurements and combined with sales data and a vehicle fleet model to estimate total excess NO[subscript x] emissions. These emissions are distributed on a 25 by 28 km grid covering Europe, using the German Federal Environmental Protection Agency's (UBA) estimate of the spatial distribution of NO[subscript x] emissions from passenger cars in Germany. We use the GEOS-Chem chemistry-transport model to predict the corresponding increase in population exposure to fine particulate matter and ozone in the European Union, Switzerland, and Norway, and a set of concentration-response functions to estimate mortality outcomes in terms of early deaths and of life-years lost. Integrated over the sales period (2008–2015), we estimate median mortality impacts from VW excess emissions in Germany to be 1200 premature deaths in Europe, corresponding to 13 000 life-years lost and 1.9 billion EUR in costs associated with life-years lost. Approximately 60% of mortality costs occur outside Germany. For the current fleet, we estimate that if on-road emissions for all affected VW vehicles in Germany are reduced to the applicable European emission standard by the end of 2017, this would avert 29 000 life-years lost and 4.1 billion 2015 EUR in health costs (median estimates) relative to a counterfactual case with no recall. ; Germany.

APPROVED ; The work which follows examines the process by which private actors in the digital market are redefining fundamental rights through their contractual terms and practical operation. The argument is allied to works which consider ?digital constitutionalism,? the idea that private actors in the digital market are increasingly displaying constitutional features through their contractual terms and documents. Unlike a majority of work in the area of digital constitutionalism the work does not argue that private actors setting rights based standards represents a positive development. Rather, the work argues that private actors, through their re-definition of public, normative standards are generating a body of rules and practices which have displaced democratically decided rights standards with negative consequences for individual autonomy and the Rule of Law. The work argues that this process has been enabled by three features of EU law and policy. The first is an approach of functional equivalence to laws governing the digital market. In accordance with this approach the digital market has been treated as equivalent to traditional markets and its participants are viewed as requiring no additional or supplementary protections or regulations. Of particular significance in functionally equivalent attitudes to the digital market is the Union?s deference to freedom of contract as part of an ordoliberal attitude to market regulation. While this attitude is now beginning to erode (to some extent) in the context of data protection it remains the dominant regulatory approach of the European Union in the digital market. The second feature, not unrelated to the first, is the Union?s preference for economic rather than socially orientated standards and protections in it policies as well as its secondary laws. As part of this preference, when fundamental rights cross the Rubicon from vertically enforced constitutional protections to horizontally enforceable legislative ones their content is transmuted in a manner which favours their economic over socially oriented aspects. The third feature, is what is referred to within the work as the Union?s brittle constitutionalism ? that is the Union?s hesitant and incomplete articulation of and commitment to rights enforcement. This feature is the result in part of the Union?s ambiguous and at times hostile attitude to the development of fundamental rights policy. The work examines the impact of these trends and the rise of private policy they have generated on the rights to privacy and property under the Charter of Fundamental Rights.
This work assesses the capacity of a microalgae-based system to remove three highly to medium polar pesticides typically found in freshwater: acetamiprid, bentazone, and propanil. Degradation of the pesticides was firstly studied individually at batch lab-scale reactors and abiotic and heated-killed controls were employed to clarify their removal pathways. At lab-scale, propanil and acetamiprid were completely removed after 7 days whereas bentazone was not removed. Four and two transformation products (TPs) were generated in the biodegradation process for acetamiprid and propanil, respectively. Then, the simultaneous removal of the pesticides was assessed in an outdoor pilot photobioreactor, operated with a hydraulic residence time of 8 days. During the steady-state, high removal efficiencies were observed for propanil (99%) and acetamiprid (71%). The results from batch experiments suggest that removal is mainly caused by algal-mediated biodegradation. Acetamiprid TPs raised throughout the operational time in the photobioreactor, while no propanil TP was detected at the pilot-scale. This suggests complete mineralization of propanil or residual formation of its TPs at concentrations below the analytical method detection limit. Aiming at biomass valorization, diverse microalgae harvesting methods were investigated for biomass concentration, and the effect of residual pesticides on the biogas yield was determined by biochemical methane potential tests. Anaerobic digestion was not inhibited by the pesticides as verified by the digestion performance. The results highlight the potential of microalgae-based systems to couple nutrient removal, biomass production, micropollutant biodegradation, and biofuel production. ; This work has been supported by the Spanish Ministry of Economy and Competitiveness State Research Agency (CTM2016-75587-C2-1-R and CTM2016-75587-C2-2-R) and co-financed by the European Union through the European Regional Development Fund (ERDF) and the Horizon 2020 research and innovation WATERPROTECT project (727450).

The present research aims to analyse the phenomenon of unaccompanied minors arriving from Morocco to the European Union from 2010 to 2021. This recent migratory phenomenon supposes an emerging challenge for governments, international organisations, and societies, in order to guarantee the protection of children according the UN Convention on the Rights of the Child (UN, 1989). The research focuses on the children «on the move», travelling alone from Morocco and arriving in Spain through the Strait of Gibraltar. The so-called Western Mediterranean Migratory Route has become one of the gateways to Europe. Spain hosts nowadays a big community of Moroccan unaccompanied minors and Catalonia has become the second Spanish Autonomous Community with a major number of unaccompanied minors, only surpassed by the enclave of Melilla located on the very border of Morocco. The present research gives special attention to the study of the Amazigh Nationalism question, as something to look at among the reasons why Moroccan unaccompanied minors migrate to Europe, choosing, particularly, Catalonia as a model to pursuit an Amazigh nation. ; A presente pesquisa tem como objetivo analisar o fenómeno da chegada de menores não acompanhados provenientes de Marrocos à União Europeia entre 2010 a 2021.

This study provides new knowledge on the mobility, behavior, and partitioning of 17 perfluoroalkyl substances (PFASs) in the water-sediment-plant system along the Dongzhulong and Xiaoqing Rivers. The fate of PFASs in these rivers is also discussed. The study area is affected by the industrial production of perfluorooctanoic acid (PFOA). The ∑PFASs in water and sediments close to the industrial discharge were 84,000 ± 2000 ng/L and 2300 ± 200 ng/g dw, respectively, with the concentrations decreasing along the river due to dilution. PFOA was the dominant compound (74–97% of the ∑PFASs), although other PFASs were identified close to urban areas. Principal component analysis and solid-liquid distribution coefficients revealed that long-chain PFASs accumulated in the sediment whereas short-chain PFASs remained in the water all along the river. PFASs were taken up by plants and remobilized to different plant compartments according to shoot concentration factors (SCFs), root concentration factors (RCF), and transfer factors (TFs). Among the four plant species studied, floating plants absorbed high levels of PFASs, while rooted species translocated short-chain PFASs from the roots to the shoots. Therefore, floating species, due to their high uptake capacity and large proliferation rate, could eventually be used for phytoremediation. ; Pere Colomer Vidal acknowledges the funding from the European Union Europe Aid 'SEW-REAP' project [ECRIP ICI+/2014/348–010].

Research indicates that sources of work-related stress (WRS) impact on the physical, social, and psychological health of pilots. Furthermore, specific features of the job can increase a pilot?s risk in relation to developing a mental health (MH) issue. It is impossible to remove all stress from the work life of pilots. A high stress situation may not necessarily be det-rimental to the person, once they have learned to cope with it in a healthy manner. Nonetheless, risk pertaining to WRS need to be effectively managed by a pilot?s employer. Therefore, it is important to identify solutions at an airline and pilot self-management level. This paper reports on the findings of human factors research undertaken with commercial pilots pertaining to work-related stress (WRS) and its impact on wellbeing, performance, and safety. The findings of a series of co-design workshops and a follow-up anonymous survey were analysed to identify potential solutions at (1) an airline and (2) pilot self-management level. Potential solutions are framed in relation to six impact scenarios. Furthermore, they are located within the existing regulatory framework, including the latest implementation rules (IR), acceptable means of compliance (ACM), and guidance material (GM) as outlined by the European Union Aviation Safety Agency (EASA 2019). Proposed interventions should promote wellbeing and positive mental health while also addressing suffering and mental ill health. Airline interventions might focus on enhancing existing Safety Management System (SMS) approaches to better manage risks pertaining to WRS, advancing new tools to enable wellbeing briefing, risk assessment, and reporting, and training pilots in relation to MH awareness, risk identifying behaviour, and coping strategies. Furthermore, new role/functions might be introduced to support the implementation and management of WRS/wellbeing/MH safety/risk processes at an airline level. Requirements for new digital tools to support pilot awareness of WRS/wellbeing/MH, self-management of WRS/wellbeing/MH and risk identification both inside and outside the cockpit are also proposed. Some of recommendations arising in this research require changes to the existing rule-making and/or modification to existing AMC and GM.
A common approach used to mitigate riverbank erosion and maintain watercourse alignments has been through the application of riprap or larger, more stable particles to channel boundaries along reaches of interest. However, very often, these large particles become dislodged from their intended locations (failed erosion measures), becoming part of the bed material composition. In natural systems, large immobile sediments or boulders can also be found, which are often sourced from glacial erratics or colluvial inputs with different spacing and arrangements among them. In lower gradient gravel-bed channels, the impacts that large clasts may impart on river morphologies are uncertain and are studied in this paper. This paper utilizes laboratory experiments to evaluate the effects that varying spacing of large immobile particles in a gravel-bed channel have on sediment transport and bed morphology. The laboratory experiments consist of a series of test cases with a varying spacing of large immobile particles and one base case with no large immobile particles present. In each case, the flume bed was composed of a poorly sorted gravel mixture with a bimodal distribution of sand and gravel meant to be representative of a natural gravel-bed channel. The results of the test cases demonstrated that at a low spacing of large immobile particles, the transported material and the bed material both became coarser. At a medium spacing of large immobile particles, the bed material size and erosion reached a maximum, and the coarser bed material was transported at approximately the same rate as the finer material. Finally, at a high spacing of large immobile particles, the size of the transported material and bed material sizes were similar to that of the base case, and the sediment transport also had the strongest clockwise hysteresis trend, which ultimately led to a net erosion of the gravel-bed channel. ; This projectwas supported by funding from an NSERC IPS (McKie), by the H2020-MSCA-IF-2018 programme (Marie Sklodowska-Curie Actions) of the European Union under REA grant agreement number 834329-SEDILAND (Juez) and by Water Regime Investigations and Simulations Ltd., JTB Environmental Systems Inc. and R&M Construction (Plumb). ; Peer reviewed
12 páginas.- 5 figuras.- 4 tablas.- referencias.- The Supplementary data to this article: in https://doi.org/10.1016/j.soilbio.2020.108102 ; Soil biodiversity loss due to pollution may affect ecosystem services negatively. This environmental problem may be solved by phytoremediation, which is an effective strategy to manage and remediate contaminated areas. During this remediation process, the establishment of plant communities may improve soil fungal community structure and, in particular, may favour mycorrhizal symbiotic associations. As a consequence, afforestation of degraded lands will have different outcomes on fungal diversity and functionality, which will depend on the selected tree and shrub species. We analysed soil fungal diversity and functional guilds by high-throughput sequencing of environmental DNA in a trace element contaminated area, part of a large scale phytoremediation project running for 20 years. We selected five habitats for comparison purposes: three under the canopy of selected tree species (wild olive, white poplar and stone pine), adjacent treeless areas (grassland) and non-remediated areas (bare soil). Soil fungal diversity and richness seemed to be enhanced by phytoremediation. White poplar soil had the highest diversity and richness compared to wild olive and stone pine. Fungal communities were especially different between stone pine, with soils rich in organic C and high C:N ratio, and grassland soils. We identified 9,428 fungal OTUs from which 1,283 were assigned to a unique functional guild; the most abundant belonging to saprotrophic, plant pathogenic and ectomycorrhizal functional guilds. Ectomycorrhizal fungi were more abundant in soils under ectomycorrhizal host trees. Saprotrophs were abundant in grassland and wild olive soils, while plant pathogens were abundant in non-remediated soils. The remediation of soils (clean-up and amendment addition) allowed the natural establishment of grassland habitats throughout the study area, increasing fungal diversity, richness, taxonomy and functionality, when compared to non-remediated soils. Tree afforestation allowed the establishment of a forest type community bringing a further recruitment of fungal taxa, mainly the ectomycorrhizal fungal guild. Afforestation with different tree species showed species-specific effects on soil N, organic C, Ca and C:N ratio which led to increased spatial heterogeneity in areas with potential to recruit a wider diversity of fungi. ; This work was supported by European Union Seventh Framework Programme (FP7/2007–2013) [grant number 603498 - RECARE], and Spanish Ministry of Science, Innovation and Universities [grants number CGL2014-52858-R – RESTECO and CGL2017-82254-R – INTARSU].
