    International audienceWe created an archive for European acceleration data, based on distributed database of accelerogram waveforms, accessed through the new European Earthquake Data Portal (http://www.seismicportal.eu). Data are open to the scientific and engineering community. Currently the 6 core partners contribute data from 1,379 earthquakes with magnitudes ranging from M1.0 to M7.4. Strong Motion Data are available with epicentral distances up to 1,000 km. Additionally, agencies are encouraged to contribute data. Waveforms included in the database are uniformly processed to create a set of engineering parameters that are used to search the database. In addition to the database, we compiled a survey of the existing accelerometric stations in the Euro-Mediterranean region. We expect this platform to be the basis for growing sharing of European Strong Motion Data in an open environment, in as near to real-time as is possible from network operators

    We consider Bianchi VI spacetime, which also can be reduced to Bianchi types VI0-V-III-I. We initially consider the most general form of the energy-momentum tensor which yields anisotropic stress and heat flow. We then derive an energy-momentum tensor that couples with the spatial curvature in a way so as to cancel out the terms that arise due to the spatial curvature in the evolution equations of the Einstein field equations. We obtain exact solutions for the universes indefinetly expanding with constant mean deceleration parameter. The solutions are beriefly discussed for each Bianchi type. The dynamics of the models and fluid are examined briefly, and the models that can approach to isotropy are determined. We conclude that even if the observed universe is almost isotropic, this does not necessarily imply the isotropy of the fluid (e.g., dark energy) affecting the evolution of the universe within the context of general relativity.Comment: 17 pages, no figures; to appear in International Journal of Theoretical Physics; in this version (which is more concise) an equation added, some references updated and adde

    Use of technology enabled learning for distance education in the health field is growing, and new challenges are emerging related to reaching health professionals working in remote areas. The Open University of the Unified Health System (UNA-SUS) promotes Continuing Professional Development and uses Technology Enhanced Learning (TEL) for distance education to theBrazilian health workforce, mainly in primary care. Methods: As part of ongoing quality assurance assessments, we performed a descriptive analysis of courses, learners, and completion rates from all enrolments in UNA-SUS for Qualification and Specialisation Courses. Data were collected directly from the UNA-SUS information system. Results: From March 2008 to October 2015 (91 months), UNA-SUS had 206,834 enrolments in 40 Specialisation Courses and 60 Qualification Courses, reaching 119,109 professionals (mean - 1.7 courses per person). These were distributed amongst 5,199 Brazilian municipalities, 59% of which had a population of 10,000 to 50,000 inhabitants. Learners were mainly women (80.6%), nurses (26.4%), and working in primary care (39.8%). Completion rates were 67.3% for Specialisation Courses and 37.9% for Qualification Courses, which were self-instructional. Reaching 93% of all Brazilian cities and 119,109 learners, UNA-SUS was able to deliver health education to health professionals (physicians, nurses, and others) in rural and other areas of shortage such as indigenous districts and metropolitan outskirts. UNA-SUS has succeeded in expanding ten-fold the seats for Specialisation Courses for family health, and has good results in TEL Qualification Courses. UNA-SUS has innovated Continuing Professional Development for health professionals in Brazil. These courses responded to the previously unattended educational needs of the workforce, focusing on reaching primary care professionals in smaller towns and remote areas. UNA-SUS is consolidating itself as a nationwide provider of continuing education

    Objetivo: descrever a constru??o de estrat?gias educacionais e o perfil dos egressos dos dois primeiros cursos autoinstrucionais do Programa de Qualifica??o em Sa?de da Pessoa Idosa (PQSPI). M?todo: an?lise descritiva do perfil de egressos do PQSPI, a partir de banco de dados consolidado da Universidade Aberta do SUS (UNA-SUS), em cursos desenhados sob constru??o reversa. Cursos conceberam-se sob dois formatos diferentes, desenvolvidos por tr?s equipes distintas, com a parceria e homologa??o da Coordena??o de Sa?de da Pessoa Idosa do Minist?rio da Sa?de. Resultados: foram desenvolvidos dois cursos, distribu?dos em sete ofertas, entre 2016 e 2018, voltados para: profissionais de n?vel superior, especialmente m?dicos/enfermeiros, curso 1; e t?cnicos/auxiliares de enfermagem (TAE) e agentes comunit?rios de sa?de (ACS), curso 2. O p?blico mais comum em todos os cursos foi de estudantes (37,9%). Dentre os profissionais, os TAE superaram m?dicos e os ACS foram o 4? p?blico mais frequente no curso 1; no curso 2, os TAE e os ACS foram os mais frequentes, com taxas de conclus?o em torno de 50%. Conclus?o: demonstrou-se maior interesse de estudantes, TAE e ACS nos cursos autoinstrucionais, sendo necess?rio estudar melhor sua participa??o. Os TAE e ACS t?m menos oportunidade de capacita??o, sendo um p?blico estrat?gico para a??es futuras.Aims: to describe the construction strategy and the learners? profile of the two initial selfinstructional courses on the Health of the Elderly Qualification Program (PQSPI). Method: descriptive analysis of the PQSPI learner?s profile from the Open University of SUS (UNASUS) consolidated database. The courses were designed based on reverse construction, when the learning objectives are the first to be drawn, followed by the activities, and then, the theoretical content is developed from it. The reverse construction involved 5 different formats, 3 production teams, and was approved by the Coordination of the Elderly from the Ministry of Health. Results: two courses with 7 educational offers were developed, directed to: graduated professionals, mainly physicians and nurses, course 1; Nursing technicians/assistants (NTA) and community health agents (CHA), course 2. The most common public for all courses was mainly composed by graduation students, demonstrating undergraduate?s interest in permanent education courses. NTA outperformed physicians and CHA were the fourth most common professional audience in course 1. In course 2, NTA and CHA were the most common audience and had completion rates around 50%. Conclusion: greater interest from students, NTA, and CHA in self-instructional courses was demonstrated, so it?s necessary to study in depth their participation. NTA and CHA have less opportunity for competencies building, being a strategic audience for future actions

    A Aten??o Domiciliar (AD) configura-se numa ?rea de atua??o de diversos especialistas, como M?dicos de Fam?lia e Comunidade, Geriatras, Pediatras e Internistas. Por suas especificidades e dentro do seu campo de pr?ticas, demanda compet?ncias que n?o est?o contempladas isoladamente em nenhuma especialidade m?dica, sendo que o tempo e a estrutura necess?rios para a aquisi??o destas ultrapassa a capacidade de inser??o ao longo dos programas atuais. A expans?o desta modalidade de cuidados representa uma demanda crescente de forma??o, exigindo a inclus?o da AD como potencial campo de trabalho destes especialistas, concebendo a necessidade de um ano adicional para forma??o nas especificidades dessa ?rea de atua??o. Discutem-se as estrat?gias de forma??o, campos da pr?tica e estrutura program?tica necess?rios para a consolida??o desta proposta. Espera-se que este artigo possa subsidiar a natural constru??o desta especialidade no ?mbito da atua??o m?dica em sa?de.Home Care (HC) is an expertise area for several specialists, such as Family Physicians, Geriatricians, Pediatricians and Internal Medicine. Due to its specificities and within its practice field, it demands competences that are not contemplated apart in any medical specialty, and the time and structure required to acquire them surpasses the insertion capacity in the current programs. This care type expansion represents a growing demand for training, requiring HC inclusion as a potential field of work for these specialists, conceiving the need for an additional year for the formation of specific features as an activity area. We discuss training strategies, practice fields and programmatic structure required to consolidate this proposal. We expect that this article can subsidize the natural construction of this specialty within the scope of health medical practice

    The influence of graphene and retinoic acid (RA) ? a ?-conjugated organic semiconductor ? interface on their hybrid system is investigated. The physical properties of the interface are assessed via scanning probe microscopy, optical spectroscopy (photoluminescence and Raman) and ab initio calculations. The graphene/RA interaction induces the formation of a well-organized ?-conjugated self-assembled monolayer (SAM) at the interface. Such structural organization leads to the high optical emission efficiency of the RA SAM, even at room temperature. Additionally, photo-assisted electrical force microscopy, photo-assisted scanning Kelvin probe microscopy and Raman spectroscopy indicate a RA-induced graphene doping and photo-charge generation. Finally, the optical excitation of the RA monolayer generates surface potential changes on the hybrid system. In summary, interface-induced organized structures atop 2D materials may have an important impact on both design and operation of ?-conjugated nanomaterialbased hybrid systems
