Analysing the contribution of automotive remanufacturing to the circularity of materials

Remanufacturing can boost resource efficiency, circularity of raw materials and reduce environmental impacts. Material Flow Analysis and Life Cycle Assessment tools are integrated to assess the contribution of remanufacturing in reducing both consumption and impacts of primary resources for passenger cars. Results show that remanufacturing allows keeping within EU about 150,000 tonnes of materials, which is particularly relevant for Critical Raw Materials, such as rare-earth elements. Also, remanufacturing contributes in decreasing environmental impacts of vehicle's key components, as combustion engines (up to 79% of Global Warming Potential reduction). Further work will address data gaps and it will include current/innovative mobility

De um trabalhador de saúde mental para muitos outros: sacrifício e sacralização em tempos de covid

The experience report seeks to analyze, from the perspective of two mental health professionals from the Unified Health System (SUS), the sacrificial dimension of the health worker in the context of the COVID 19 pandemic, from June 2020 to March 2021 Initial reflections emerge about the work process in a Psychosocial Care Center (CAPS). The experience in this medium-complexity service reveals the anxieties produced by the decision-making power of the municipal health management, especially regarding the impossibility of remote work. In a second moment, reflections on specific issues reveal the national panorama of an extreme right-wing government that reiterates the sacrificial logic that emerges in the midst of the pandemic. Therefore, the concepts of power devices by Michel Foucault and Homo Sacer by Giorgio Agambem are used. Thus, the inseparability between the microsocial and macrosocial dimensions of the problems presented is perceived, and the term "frontline" is questioned in order to intersect the suffering of hospital service professionals with that of other health professionals in the SUS network, on medium complexity devices. It is concluded that the sacrificial dimension that the SUS health professional subjectively produces sustains a state of exception that, ultimately, by sacralizing the 'true heroes' also exposes them, both to the unnecessary risk of contagion and in the decisions to make a living and let it die.The experience report seeks to analyze, from the perspective of two mental health professionals from the Unified Health System (SUS), the sacrificial dimension of the health worker in the context of the COVID 19 pandemic, from June 2020 to March 2021 Initial reflections emerge about the work process in a Psychosocial Care Center (CAPS).

As reflexões iniciais emergem sobre o processo de trabalho em um Centro de Atenção Psicossocial (CAPS). A experiência nesse serviço de média complexidade revela as angústias produzidas diante do poder decisório da gestão municipal de saúde, especialmente, relativas à impossibilidade do trabalho remoto. Em um segundo momento, as reflexões sobre as problemáticas especificadas revelam o panorama nacional de um governo de extrema-direita que reitera a lógica sacrificial que emerge em meio à pandemia. Para tanto, são utilizados os conceitos de dispositivos de poder de Michel Foucault e Homo Sacer de Giorgio Agambem. É percebida, assim, a indissociabilidade entre a dimensão microssocial e macrossocial das problemáticas apresentadas, bem como colocado em questão o termo “linha de frente” a fim de interseccionar o sofrimento de profissionais de serviços hospitalares com a de outros profissionais de saúde da rede SUS, em dispositivos de média complexidade. Conclui-se que a dimensão sacrificial que produz subjetivamente o profissional de saúde do SUS sustenta um estado de exceção que em última instância, ao sacralizar os ‘verdadeiros heróis’ também os expõe, tanto ao risco desnecessário de contágio, como nas decisões de fazer viver e deixar morrer

Desempenho de juvenis de pacu alimentados com rações suplementadas com L-carnitina

The objective of this work was to determine the effect of L-carnitine supplementation on the productive performance and physiology of juvenile pacu (Piaractus mesopotamicus). A total of 288 pacu, with an initial average weight of 9.62±0.74 g, were fed experimental diets supplemented with 400, 800, 1,200, 1,600, and 2,000 mg kg-1 L-carnitine and a control diet (without supplementation), for 128 days. The following were evaluated: growth performance; carcass centesimal composition; intestinal, muscle, and hepatic histomorphologies; and oxidative stress. The fish hepatosomatic and viscerosomatic fat indexes increased with the inclusion of L-carnitine in the diets. The evaluation of carcass centesimal composition showed that the diets supplemented with 2,000 mg kg-1 L-carnitine caused a reduction in protein content and an increase in that of ethereal extract. Intestinal histomorphology indicated changes in the villi with L-carnitine supplementation. Moreover, hepatic lipid peroxidation occurred with the inclusion of 2,000 mg kg-1 L-carnitine. The supplementation with L-carnitine in the diets of pacu juveniles does not influence the development of the fish until the rate of 1,600 mg kg-1. However, high carcass lipid levels, as well as an increase in the hepatosomatic and viscerosomatic fat indexes, are observed in fish fed diets containing 2,000 mg kg-1.O objetivo deste trabalho foi determinar o efeito da suplementação de L-carnitina no desempenho produtivo e na fisiologia de juvenis de pacu (Piaractus mesopotamicus). Um total de 288 pacus, com peso inicial médio de 9,62±0,74 g, foram alimentados com dietas experimentais suplementadas com 400, 800, 1.200, 1.600 e 2.000 mg kg-1 de L-carnitina e com uma dieta controle (sem suplementação), por 128 dias. Foram avaliados: desempenho produtivo; composição centesimal da carcaça; histomorfologias intestinal, muscular e hepática; e estresse oxidativo. Os índices hepatossomático e de gordura viscerossomática dos peixes aumentaram com a inclusão de L-carnitina nas rações. A avaliação da composição centesimal da carcaça mostrou que as dietas suplementadas com 2.000 mg kg-1 de L-carnitina causaram redução no conteúdo de proteína e aumento no de extrato etéreo. A histomorfologia intestinal indicou alterações nas vilosidades com a suplementação de L-carnitina. Além disso, a peroxidação lipídica hepática ocorreu com a inclusão de 2.000 mg kg-1 de L-carnitina. A suplementação de L-carnitina em dietas para juvenis de pacu não influencia o desenvolvimento dos peixes até a dose de 1.600 mg kg-1. Entretanto, observam-se elevados níveis de lipídeos na carcaça, assim como aumento nos índices hepatossomáticos e de gordura viscerossomática, em peixes alimentados com rações contendo 2.000 mg kg-1

Indicators for monitoring the Strategic Transport Research and Innovation Agenda

The European Commission’s Transport Research and Innovation Monitoring and Information System (TRIMIS) maps and analyses research trends and innovation capacities across the European transport sector. The Strategic Transport Research and Innovation Agenda (STRIA) was adopted by the European Commission in 2017 as part of the "Europe on the move" package, which highlights main transport research and innovation priorities for a clean, connected and competitive mobility. This report presents the methodological approach and a first list of indicators that TRIMIS proposes to measure progress in European Union transport research and innovation. These indicators provide input to the further development of STRIA roadmaps and will be used to support the planned TRIMIS interactive scoreboard that will be available on the TRIMIS online platform and will be periodically updated.JRC.C.4-Sustainable Transpor

Innovation capacity in the transport sector: a European outlook: An assessment based on the Transport Research and Innovation Monitoring and Information System (TRIMIS)

The Transport Research and Innovation Monitoring and Information System (TRIMIS) is the analytical support tool for the establishment and implementation of the Strategic Transport Research and Innovation Agenda (STRIA), and is the European Commission’s (EC) instrument for mapping transport technology trends and research and innovation capacities. Seven STRIA Roadmaps have been developed which cover various thematic areas. TRIMIS provides periodical assessments of transport research and innovation (R&I) for the various thematic areas. This report provides a macro-level assessment of the overall innovation capacity in the European transport sector and complements the analysis with the results of an Innovation Capacity survey distributed to private and public transport stakeholders aiming at gathering insights on transport research trends, drivers and enablers, challenges, role of policy measures, etc. This report updates the previous TRIMIS report on the topic and complements the analysis with the results of a TRIMIS stakeholder survey. The finding of the analysis show that research and development (R&D) activities are key in transport, where the private sector is mostly engaged. Business investments in R&D in the transport sector amounted to more than €47 billion in 2017 and total European public investment in transport R&D in 2018 was equal to €2.9 billion. Transport researchers and R&D personnel amounted to 309.000 people working in the European transport sector in 2017, the majority of them working in the automotive industry. The outcomes of the TRIMIS survey reflect the views and opinions of transport stakeholders. The results show an almost unanimous opinion in relation to the key role that R&I plays in relation to the quality of the services or goods provided, moreover the competitiveness of the transport sector will be enhanced when R&I activities are intensified. Although almost all the stakeholders recognised the importance of R&I, they also pointed out obstacles and barriers, such as financial constraints and management, market dynamics, lack of qualified personnel that slow down or prevent them to fully engage in such activities.JRC.C.4-Sustainable Transpor

Endoscopic submucosal dissection for the treatment of early esophageal and gastric cancer - initial experience of a western center

BACKGROUND: Endoscopic submucosal dissection is a new Japanese technique characterized by en-bloc resection of the entire lesion irrespective of size, with lower local recurrence when compared to endoscopic mucosal resection. OBJECTIVE: To evaluate the feasibility, early results and complications of the endoscopic submucosal dissection technique for treating early gastric and esophageal cancer at the Endoscopic Unit of Clinics Hospital and Cancer Institute of the São Paulo University. MATERIALS AND METHODS: Twenty patients underwent endoscopic resection using the endoscopic submucosal dissection technique for early gastric or esophageal cancer. The patients were evaluated prospectively as to the executability of the technique, the short-term results of the procedure and complications. RESULTS: Sixteen gastric adenocarcinoma lesions and six esophageal squamous carcinoma lesions were resected. In the stomach, the mean diameter of the lesions was 16.2 mm (0.6-3.5 mm). Eight lesions were type IIa + IIc, four were type IIa and four IIc, with thirteen being well differentiated and three undifferentiated. Regarding the degree of invasion, five were M2, seven were M3, two were Sm1 and one was Sm2. The mean duration of the procedures was 85 min (20-160 min). In the esophagus, all of the lesions were type IIb, with a mean diameter of 17.8 mm (6-30 mm). Regarding the degree of invasion, three were M1, one was M2, one was M3 and one was Sm1. All had free lateral and deep margins. The mean time of the procedure was 78 min (20-150 min). CONCLUSION: The endoscopic submucosal dissection technique was feasible in our service with a high success rate
