Rheological behavior of Brazilian Cherry (Eugenia uniflora L.) pulp at pasteurization temperatures

Neste trabalho, foi estudado o comportamento reológico da polpa de pitanga na faixa de temperatura de pasteurização de 83 a 97 °C. Os resultados indicaram que a polpa apresentou comportamento pseudoplástico e o modelo de Herschel-Bulkley foi considerado o mais adequado para representar o comportamento reológico do produto nas temperaturas estudadas. Os índices de comportamento de fluido (n) variaram na faixa de 0,448 a 0,627. O efeito da temperatura sobre a viscosidade aparente pôde ser descrito pela equação análoga à de Arrenhius, observando-se a diminuição da viscosidade aparente da polpa de pitanga com o aumento da temperatura.

Cicero, Tullia, and Marcus: Gender-Specific Concerns for Family Tradition?

A fair number of Cicero's letters reveal his concern for his daughter Tullia and his son Marcus. Recent scholarship has read these letters as evidence for a ‘natural’ emotional attachment of a father to his children, in reaction to Philippe Ariès's opposite claim. This chapter considers whether Cicero's letters can be analysed only as expressions of paternal affection. The fact that the pater familias Cicero occupies a political position simultaneously in his nuclear family, his domus, and the Senate, results in a concern for his prestige within the social field of the aristocracy. And this concern is necessarily conferred upon his support of the education and the social and political career of his children. The chapter traces the gender-specific differences between Cicero's treatment of Tullia and Marcus, shows the social construction of parental affection, and contributes to a further understanding of the different functions of daughters and sons in the social force field of family memory.

Why Cherry-Picking Never Leads to Harmonisation: The Case of the Limitations on Copyright under Directive 2001/29/EC

The article examines whether the norms laid down in the Directive in relation to the exceptions and limitations on copyright and related rights can be conducive to a sensible degree of harmonisation across the European Union. Before discussing the degree of harmonisation achieved so far by the Directive, the first part gives a short overview of the main characteristics of the list of exceptions and limitations contained in Article 5 of the Directive. A comprehensive review of the implementation of each limitation by the Member States is beyond the scope of this article. The following section takes a closer look at three examples of limitations that have led to legislative changes at the Member State level as express measures towards the implementation of the Information Society Directive, that is, the limitations for the benefit of libraries, for teaching and research, and for persons with a disability. These exceptions and limitations were later on also identified by the European Commission as key elements in the deployment of a digital knowledge economy. The analysis will show that the implementation of the provisions on limitations in the Information Society Directive did not, and probably cannot, yield the expected level of harmonisation across the European Union and that, as a consequence, there still exists a significant degree of uncertainty for the stakeholders regarding the extent of permissible acts with respect to copyright protected works.
