As Santas Casas da Misericórdia na República Brasileira 1922-1945

O principal objectivo desta dissertação é o de conhecer um pouco melhor o processo de implementação das Santas Casas de Misericórdia no Brasil, dando especial ênfase à sua expansão durante o período de consolidação da República brasileira, mais concretamente entre 1922 a 1945. A necessária contextualização levou a pesquisa sobre as Misericórdias até à fase colonial e imperial do Brasil, acabando por demonstrar que as mesmas se fortaleceram no segmento de assistência médica, durante o período em análise, tomando o Estado brasileiro dependente das suas actividades. Este trabalho discute ainda o imaginário social da caridade e filantropia e a forma como tais preceitos configuraram a assistência médico-social no país. ABSTRACT; This dissertation aims to better know the implementation process of the Santas Casas de Misericórdia in Brazil, highlighting their expansion during the Republic, mainly between 1922 and 1945. For a better historical contextualization the study explores the Brazil's colonial and imperial phases, demonstrating that the Misericórdias progressively strength their power in the medical assistance segment, becoming the State dependent of their activities. The dissertation also discusses the philanthropy and charity's collective social imagery, as well as the way in which such concepts shaped the medico-social assistance in the country.

Specific shear-dependent viscoelastic third-grade fluid model

A specific modified constitutive equation for a third-grade fluid is proposed so that the model be suitable for applications where shear-thinning or shear-thickening may occur. For that, we use the Cosserat theory approach reducing the exact three-dimensional equations to a system depending only on time and on a single spatial variable. This one-dimensional system is obtained by integrating the linear momentum equation over the cross-section of the tube, taking a velocity field approximation provided by the Cosserat theory. From this reduced system, we obtain the unsteady equations for the wall shear stress and mean pressure gradient depending on the volume flow rate, Womersley number, viscoelastic coefficient and flow index over a finite section of the tube geometry with constant circular cross-section.
