    As multiple crises have unfolded in recent years, the arts and culture sector has been among the most damaged financially, and its structural fragilities have significantly deteriorated. At the same time, its value to society throughout these crises has been undoubtedly clear.This second volume of Philea's research into European philanthropic funding in the field of arts and culture reveals a philanthropic sector that is strongly committed to resourcing artistic and cultural organisations to strengthen their resilience; has a cross-cutting and intersectional tendency in its work; and is clearly open to collaborative and participatory approaches.This edition of the mapping surveyed 64 foundations from 17 different countries, and includes contributions from several experts in the field.

    Maxima of the Q-index: forbidden 4-cycle and 5-cycle

    Full text link
    This paper gives tight upper bounds on the largest eigenvalue q(G) of the signless Laplacian of graphs with no 4-cycle and no 5-cycle. If n is odd, let F_{n} be the friendship graph of order n; if n is even, let F_{n} be F_{n-1} with an edge hanged to its center. It is shown that if G is a graph of order n, with no 4-cycle, then q(G)<q(F_{n}), unless G=F_{n}. Let S_{n,k} be the join of a complete graph of order k and an independent set of order n-k. It is shown that if G is a graph of order n, with no 5-cycle, then q(G)<q(S_{n,2}), unless G=S_{n,k}. It is shown that these results are significant in spectral extremal graph problems. Two conjectures are formulated for the maximum q(G) of graphs with forbidden cycles.Comment: 12 page

    Child and Youth Participation in Philanthropy : Stories of Transformation

    Get PDF
    This study represents another milestone on the journey of supporting philanthropic practice in becoming more inclusive and closer to those it serves. It is based on: a survey of and interviews with 40 European philanthropic organisations; focus group interviews with children and young people involved with these organisations; and 11 case studies of participating organisations. The study provides recommendations and clear examples of initiatives by foundations along this journey, which can be used to spark discussion on the various modes and phases of participatory philanthropy, whatever the target group or thematic area

    Experimental and Modelling Analysis of Char Decomposition: Experiences with Real Scale Gasification Systems

    Get PDF
    Abstract The main issue to be faced when dealing with gasification processes is the removal of tars in order to obtain a good quality producer gas for later use, either as energy vector or for production of chemicals. Char has been observed to have a high potential for catalytic tar reduction, but the properties that promote this activity are still being investigated. An understanding of the mechanisms involved in the process of tar removal is needed, including the deactivation of the char as a catalyst and its degradation. This work addresses the process of thermal decomposition of char with different operating conditions and under inert atmosphere (N 2 ), in order to determine the mass loss occurring under high temperature treatment. For this purpose, chars collected from local gasification plants have been used. Firstly, a complete characterization of the chars has been carried out to determine their composition, heating value and BET surface area. Secondly, thermogravimetric analyses have been used to calibrate a one-step kinetic model for describing the kinetics involved in the process of char thermal decomposition. The coupling of the kinetics with a CFD model allowed then to consider mass, heat, and momentum transfer phenomena, and to quantitatively estimate the decomposition in a fixed-bed test reactor. The model, whose results have been compared to reference experimental tests, predicts satisfactorily the thermal behavior of the char inside the reactor and its mass loss

    Gasification Char as a Potential Substitute of Activated Carbon in Adsorption Applications

    Abstract This study points out the similarities between char from biomass gasification and activated carbon and reviews its successful applications in the field of adsorption. Surface area (S BET ) is considered as the standard parameter. Since only few data on biomass gasification char are available in the literature, in this work char residues from different commercial gasification plants were collected and characterized, reporting their S BET values for comparison. The highest values for S BET are associated to dual-stage gasification technologies and are highly affected by the operating temperature

    Building Simulation application 2013 was the first IBPSA Italy regional conference on building performance simulation. The two-day event focused on three main subjects: simulation of building performance, actual perspectives in building physics and simulation tools. The principal mission is to promote and advance the practice of building performance simulation in order to improve the design, construction, operation and maintenance of new and existing building

    Uso emergente da teleodontologia no Brasil durante o período da pandemia de covid-19

    INTRODUÇÃO: No início de 2020, com a instalação da pandemia da doença covid-19, causada por um novo tipo de coronavírus (SARS-CoV-2), a Odontologia foi consideravelmente impactada. A teleodontologia emergiu como uma necessidade de incorporação na rotina dos atendimentos odontológicos, ocasionando sua regulamentação no Brasil, buscando garantir a autonomia dos profissionais e a segurança dos pacientes na assistência odontológica. OBJETIVOS: Este trabalho teve como objetivo principal analisar, por meio de uma revisão de literatura, o uso emergente da teleodontologia no Brasil durante o período da pandemia de covid-19. PROCEDIMENTOS METODOLÓGICOS: Em relação aos procedimentos metodológicos, trata-se de um estudo de revisão de escopo (scoping review), que utilizou descritores controlados em português e inglês, baseados nas em combinações das palavras-chave deste estudo. O período de abrangência das publicações foi de janeiro de 2020 até junho de 2021. As bases consultadas foram a Biblioteca Regional de Medicina (BIREME), National Library of Medicine (MEDLINE/PubMed) e o Google Acadêmico. Foram excluídas as produções científicas não relacionadas com o escopo do estudo, as produções duplicadas, cartas e trabalhos não realizados no Brasil. Os artigos selecionados foram obtidos na íntegra e analisados pela técnica da análise de conteúdo (qualitativa). RESULTADOS: Após o refinamento e avaliação dos títulos e resumos das 622 publicações potenciais encontradas, foram selecionadas 28 publicações, compondo os resultados e discussões deste trabalho. Mediante a análise destes, observou-se que a pandemia pelo novo coronavírus aumentou o oferecimento dos serviços de teleodontologia, como alternativa viável ao atendimento odontológico não presencial. Verificou-se também que esta ferramenta se apresentou eficaz na função de telemonitorar e teleorientar os pacientes, reduzindo as exposições desnecessárias aos serviços de saúde presenciais, diminuindo as possibilidades de contágio pelo vírus, bem como sua propagação. CONCLUSÕES: Conclui-se que a utilização da teleodontologia como ferramenta de apoio à saúde pública no Brasil apresentou importância significativa durante o período da pandemia, mesmo esta não tendo acabado, foi possível verificar os efeitos positivos causados no âmbito dos cuidados com a saúde bucal dos pacientes, oferecendo uma alternativa viável, de baixo custo e eficiente para o acompanhamento dos mesmos
