The Infusion of Brazilian Musical Elements and Culture and How these inform the Collaborative Pianist in Mozart Camargo Guarnieri’s Treze Cancoes de Amor

This document studies the Brazilian musical and cultural elements of rhythm, dance genres, and the Portuguese language used by Camargo Guarnieri in his song cycle Treze Cancoes de Amor. The purpose of this project is to inform the reader of performance practices related to Brazilian traditions specific to these songs, and to point out challenges in performance, especially for non-native Brazilian pianists. The research was based on findings of Camargo Guarnieri, such as books, dissertations, and recorded interviews and score study of the song cycle\u27s manuscript. In addition, an Interview was conducted with Maria José Carrasqueira, Brazilian pianist and former student of Guarnieri, and several discussions with non-Brazilian pianists and singers

Determinants of sovereign bond yield spreads in the euro area in

This paper aims to identify the determinants behind the different evolution of sovereign bond yields in euro area countries for the period of the current crisis. Up to the time of the collapse of Lehman Brothers, global risk premium was the main driver of spreads. Afterwards, the relevance of idiosyncratic factors increased. Although liquidity premiums played a larger role in the months following September 2008, as the financial crisis spilled over into a strongly deteriorating macroeconomic environment, the importance of country credit risk factors increased. In the first five months of 2010, heterogeneity in sovereign credit risk premiums and a further increase in global risk aversion were, to a large extent, the determining factors behind the evolution of spreads.

Investment Timing and Social Welfare under Feed-in Tariff Contract

This paper presents a novel model to analyze the effects on the investment timing and social welfare of three feed-in tariffs (FIT) within an oligopolistic market structure. The FIT contracts are the fixed price, the fixed premium, and the minimum price guarantee. The model allows the identification of the optimal time to deploy a renewable energy project and the value of the tariff that maximizes the social welfare for each FIT design. These optimal tariffs generate the same investment timing and the same social welfare

Morphological and Physicochemical Properties of Macrocrystalline Talc from Argentine

A detailed petrographical, mineralogical, morphological, geochemical and physicochemical characterization of talc from an Argentinean ore is presented. This deposit is located in the San Juan province at the foothills of the Andes. Characterization was performed on rock and milled talc using different techniques including polarized light microscopy, transmission electron and scanning microscopy with energy dispersive spectroscopy (SEM/EDX), chemical analyses, X-ray diffraction (XRD), X-ray fluorescence, Fourier transform infrared spectroscopy (FTIR), particle size determination by laser diffraction, thermogravimetry analysis, and colorimetry. A mineral sample contains approximately 80 wt% talc. Associated minerals such as carbonates as veins and chlorite interlaminated with talc were detected. Carbonates are calcite, dolomite and magnesite, as was corroborated by FTIR. Morphology and crystallinity were assessed by XRD data, obtaining a morphological index of 0.79 which indicates the macrocrystalline character. Crystalline habits of associated minerals were recognized by SEM, detecting their constitutive elements by EDX. Talc color parameters are L* = 82.76, a* = −1.50, and b* = 5.38. The slight yellowing could be attributed to chlorite or traces of Fe oxides. Although the whiteness index (62.12) impedes its commercialization as a high-priced mineral, this kind of talc can be used as an additive for polymers, since it would offer a high reinforcing effect (improvement of mechanical properties).Fil: Barbosa, Silvia Elena.

Comparative analysis of crystallization behavior induced by different mineral fillers in polypropylene nanocomposites

A comparative analysis of crystallization behavior induced by several mineral fillers in polypropylene nanocomposites was performed. Morphological changes and thermal properties of nanocomposites were evaluated, considering the influence of shape, crystalline morphology, and concentration of mineral particles. For this study, hydrated magnesium silicates with different particle morphologies, such as platelets (talc) and fibers (sepiolite), were used for nanocomposites. In addition, to analyze the effect of mineral crystallinity on nanocomposites, talc and sepiolite from different origin and genesis were selected. Nanocomposites were compounded and injection molded, using different filler concentration (0, 1, and 3% w/w) for each mineral particle. To evaluate the particle influence on nanocomposite crystallinity, X-ray diffraction was used to determine crystalline phases and crystal orientation, meanwhile differential scanning calorimetry was performed to obtain thermal properties. Main results revealed that talc has a higher nucleating effect on polypropylene matrix than sepiolite fibers, regardless of their origin and genesis. Meanwhile, a transcrystalline layer that surrounds the fiber surface is observed for nanocomposite containing sepiolite. Moreover, Argentinean talc induces different crystalline phases in nanocomposite with respect to Australian one, which partly influences on mechanical properties.Fil: Castillo, Luciana Andrea.

Redes canábicas e usos medicinais de maconha: : associativismo como parte do processo terapêutico

This article aims to build an overview of how social actors are mobilized around access to marijuana for medicinal purposes in Brazil, especially about collective actions promoted between 2014 and 2019 through cannabis associations. From ethnographic research carried out with Brazilian cannabis associations, and through the analysis of documents and public hearings, it was understood that activism around the topic has resulted in greater access to such treatment, through civil disobedience and the judicialization of health. As the knowledge needed to carry out cannabis treatment has not been produced by medical institutions or research institutes, to access them it is necessary to engage in cannabis collectives or associations. In this sense, engagement promotes greater access to health since such movements have resulted in possibilities for such treatment. In addition, the credibility and legitimacy achieved by cannabis associations have the potential to expand the democratization of the debate on the topic of cannabis, as they increase social participation in decision-making processes, and demand democratic means of access.O presente artigo tem como objetivo construir um panorama sobre como se mobilizam os atores sociais em torno do acesso à maconha para fins medicinais no Brasil, especialmente no que se refere às ações coletivas promovidas entre os anos de 2014 e 2019 por meio do associativismo canábico. A partir de uma pesquisa etnográfica realizada junto a associações canábicas brasileiras, e pela análise documental e de audiências públicas, compreendeu-se que o ativismo em torno do tema tem resultado no maior acesso a tal tratamento, por meio da desobediência civil e da judicialização da saúde. Como o conhecimento necessário para realizar o tratamento com cannabis não tem sido produzido pelas instituições médicas ou institutos de pesquisa, para acessá-los é necessário engajar-se em coletivos ou associações canábicas. Nesse sentido, o engajamento promove o maior acesso à saúde, uma vez que tais movimentos têm resultado em possibilidades para tal tratamento. Além disso, a credibilidade e legitimidade alcançada pelas associações canábicas tem potencial para ampliar a democratização do debate sobre o tema da cannabis, uma vez que aumentam a participação social nos processos de tomada de decisão, e demandam meios democráticos de acesso
