The market for photovoltaic solar energy is in a stage of strong growth, worldwide. Such growth is fostered by national and international regulatory frameworks, designed to launch and secure large scale diffusion of the technology. Brazil is considered one of the most promising markets for photovoltaic energy mainly due to favourable conditions for the implementation of this kind of generation. However, the representativeness of solar power in the Brazilian electricity matrix remains lower than expected which opens the door to interesting considerations. The current study investigates the adequacy of the most important energy policies, legislation, regulations, economic, financial and fiscal support schemes In this context, a comprehensive review of the Brazilian regulatory framework for photovoltaic energy was developed. Then some semi structured interviews with photovoltaic professionals were conducted to explore policy adequacy in a deeper way. The study finds that, despite the current regulatory framework having driven significant photovoltaic development in Brazil, urgent improvements are currently needed. To follow a process of modernization of the electricity sector, the recommendation for Brazil is to create a more coherent, stable, open and competitive regulatory framework, both for centralized and distributed photovoltaic generation. ; O mercado de energia solar fotovoltaica encontra-se em fase de forte crescimento mundial. Esse crescimento é promovido por estruturas regulatórias nacionais e internacionais, projetadas para iniciar e garantir a difusão em larga escala da tecnologia. O Brasil é considerado um dos mercados mais promissores para o sucesso da energia fotovoltaica, principalmente graças às condições favoráveis para a implantação deste tipo de geração. No entanto, a representatividade da energia solar na matriz elétrica brasileira continua abaixo do esperado o que abre a porta para considerações interessantes. O presente estudo investiga a adequação das mais importantes políticas energéticas, da legislação da regulamentação e dos apoios económicos, financeiros e fiscais. Nesse contexto, foi desenvolvida uma ampla revisão do marco regulatório brasileiro para a energia fotovoltaica. Depois disso, foram realizadas algumas entrevistas semiestruturadas com profissionais do setor para explorar essa adequação da política de uma forma mais aprofundada. O estudo conclui que, apesar do quadro regulatório atual ter impulsionado um desenvolvimento fotovoltaico significativo no Brasil, melhorias urgentes são atualmente necessárias. Para acompanhar um processo de modernização do setor elétrico, a recomendação para o Brasil é a criação de um marco regulatório mais coerente, estável, aberto e competitivo, tanto para o setor fotovoltaico centralizado quanto para a geração distribuída.

Inhalation of sulfur mustard (SM), a bifunctional alkylating agent that causes severe lung damage, is a significant threat to both military and civilian populations. The mechanisms mediating its cytotoxic effects are unknown and were investigated in the present studies. Male rats Crl:CD(SD) were anesthetized, and then intratracheally intubated and exposed to 0.7–1.4 mg/kg SM by vapor inhalation. Animals were euthanized 6, 24, 48 h or 7 days post-exposure and bronchoalveolar lavage fluid (BAL) and lung tissue collected. Exposure of rats to SM resulted in rapid pulmonary toxicity, including focal ulceration and detachment of the trachea and bronchial epithelia from underlying mucosa, thickening of alveolar septal walls and increased numbers of inflammatory cells in the tissue. There was also evidence of autophagy and apoptosis in the tissue. This was correlated with increased BAL protein content, a marker of injury to the alveolar epithelial lining. SM exposure also resulted in increased expression of markers of inflammation including cyclooxygenase-2 (COX-2), tumor necrosis factor-α (TNFα), inducible nitric oxide synthase (iNOS), and matrix metalloproteinase-9 (MMP-9), each of which has been implicated in pulmonary toxicity. Whereas COX-2, TNFα and iNOS were mainly localized in alveolar regions, MMP-9 was prominent in bronchial epithelium. In contrast, expression of the anti-oxidant hemeoxygenase, and the anti-inflammatory collectin, surfactant protein-D, decreased in the lung after SM exposure. These data demonstrate that SM-induced oxidative stress and injury are associated with the generation of cytotoxic inflammatory proteins which may contribute to the pathogenic response to this vesicant.

The SuperB asymmetric e+ - e− collider has been recently approved by the Italian Government. With a design luminosity two orders of magnitude greater than the past B-Factories and by exploiting the low-energy beam polarization, within few years it is expected to start the study of rare B and D meson decays, where New Physics might show up, and lepton flavour violation in tau decays. Due to the reduced center of mass boost, the vertex resolution must be improved to achieve the same proper-time difference resolution for B decays obtained in BaBar. Thus, based on the layout of the BaBar vertex detector, the SuperB Silicon Vertex Tracker must be equipped with an extra innermost layer (the Layer0), very close to the interaction point. The most stringent physics requirements concern the low material budget and the high-background working conditions of the Layer0: striplets modules, with short strips on high resistivity silicon sensors, are the baseline solution foreseen for the beginning of data taking; an upgrade to pixel sensors, more robust against high background occupancy, is planned at the full luminosity. The latest results on the various pixel options explored by a specific R&D program on different pixel technologies will be described: CMOS MAPS, pixel sensors realized on multiple layers with a vertical integration technology and hybrid pixels.
