THE GALICIAN-PORTUGUESE LYRIC AND THE 17TH-CENTURY LOVE POETRY: ARTS OF LOVE, SONGS AND WRITTEN SONGS

In this paper, we discuss important echoes of Galician-Portuguese lyric that remain in the 17th-century love lyric poetry produced in Portugal. In order to achieve this main objective, we highlight some specificities of the troubadours’ lyric and of the 17th-century poetry, particularly the fundamentally musical character of the troubadours’ songs as opposed to the fundamentally written character of the 17th-century poems. This contrast indicates that they are compositions from different times (predominantly the 13th and the 17th centuries) and produced according to distinct poetic conceptions. However, they are compositions which are also similar in many ways, and whose similarities, especially regarding the lyrical genre, point to similar quests for perfect practice of love, outlining “arts of love” understood as unsystematic precepts of loving which are practiced in poetry. In this article, we intend to show that these poetic loves are technically conceived and, as historical constructs, they differ from each other, since they are characterized by their peculiar moments of achievement. However, they are not isolated in the time. As mentioned above, the troubadours’ songs are essentially musical while the 17th-century poems, as indicated by the prevalent poetic preceptive in their time, are essentially written. Nevertheless, those trobar songs reverberate in these poems (“written songs”) and in both kinds we read and listen to similar precepts of love, as though we were in labyrinths of love echoes with no way out.

Micropolar flow in a porous channel with high mass transfer

Two dimensional flow of a micropolar fluid in a porous channel is investigated. The flow is driven by suction or injection at the channel walls, and the micropolar model due to Eringen is used to describe the working fluid. An extension of Berman's similarity transform is used to reduce the governing equations to a set of non-linear coupled ordinary differential equations. The latter are solved for large mass transfer via a perturbation analysis where the inverse of the cross-flow Reynolds number is used as the perturbing parameter. Complementary numerical solutions for strong injection are also obtained using a quasilinearisation scheme, and good agreement is observed between the solutions obtained from the perturbation analysis and the computations.

Feminist Disability Theory: Domestic Violence Against Women with a Disability

Women with a disability continue to experience social oppression and domestic violence as a consequence of gender and disability dimensions. Current explanations of domestic violence and disability inadequately explain several features that lead women who have a disability to experience violent situations. This article incorporates both disability and material feminist theory as an alternative explanation to the dominant approaches (psychological and sociological traditions) of conceptualising domestic violence. This paper is informed by a study which was concerned with examining the nature and perceptions of violence against women with a physical impairment. The emerging analytical framework integrating material feminist interpretations and disability theory provided a basis for exploring gender and disability dimensions. Insight was also provided by the women who identified as having a disability in the study and who explained domestic violence in terms of a gendered and disabling experience. The article argues that material feminist interpretations and disability theory, with their emphasis on gender relations, disablism and poverty, should be used as an alternative tool for exploring the nature and consequences of violence against women with a disability.

Condensed phase combustion travelling waves with sequential exothermic or endothermic reactions

The one-dimensional propagation of a combustion wave through a premixed solid fuel for two-stage kinetics is studied. We re-examine the analysis of a single reaction travelling-wave and extend it to the case of two-stage reactions. We derive an expression for the travelling wave speed in the limit of large activation energy for both reactions. The analysis shows that when both reactions are exothermic, the wave structure is similar to the single reaction case. However, when the second reaction is endothermic, the wave structure can be significantly different from single reaction case. In particular, as might be expected, a travelling wave does not necessarily exist in this case. We establish conditions in the limiting large activation energy limit for the non-existence, and for monotonicity of the temperature profile in the travelling wave.

Sandwich complexes of naphthalocyanine with the rare earth metals

Over the past two decades and in particular the past five years, numerous sandwich-type rare earth complexes containing naphthalocyanine ligands have been synthesized. The more extended delocalized π-electron system of naphthalocyanine in comparison with phthalocyanine generates unique physical, spectroscopic, electrochemical and photoelectrochemical properties which have aroused significant research interest in these compounds. This review summarizes recent progress in research on this important class of molecular materials and overviews the current status of the field.
