A família Myrtaceae na reserva particular do patrimônio natural da Serra do Caraça, Catas Altas, Minas Gerais, Brasil

This is a floristic survey of Myrtaceae in the Serra do Caraça, Minas Gerais. Fifty two species were found belonging to 12 genera - Myrcia with 17 species, Eugenia with nine, Campomanesia and Myrciaria with five species each, Psidium with four, Siphoneugena with three, Blepharocalyx, Calyptranthes, Marlierea and Myrceugenia with two species each, and Accara and Plinia with one species each. Descriptions of the genera and species, identification keys, geographical distributions, illustrations and comments are provided. © 2005 Instituto de Ciências Biológicas - UFMG.

Optimal Boussinesq model for shallow-water waves interacting with a microstructure

In this paper, we consider the propagation of water waves in a long-wave asymptotic regime, when the bottom topography is periodic on a short length scale. We perform a multiscale asymptotic analysis of the full potential theory model and of a family of reduced Boussinesq systems parametrized by a free parameter that is the depth at which the velocity is evaluated. We obtain explicit expressions for the coefficients of the resulting effective Korteweg-de Vries (KdV) equations. We show that it is possible to choose the free parameter of the reduced model so as to match the KdV limits of the full and reduced models. Hence the reduced model is optimal regarding the embedded linear weakly dispersive and weakly nonlinear characteristics of the underlying physical problem, which has a microstructure. We also discuss the impact of the rough bottom on the effective wave propagation. In particular, nonlinearity is enhanced and we can distinguish two regimes depending on the period of the bottom where the dispersion is either enhanced or reduced compared to the flat bottom case. © 2007 The American Physical Society.

Homologies of floral structures in velloziaceae with particular reference to the corona

New data on floral morphology, development, and vasculature in two Brazilian genera of the monocot family Velloziaceae (Pandanales) are used to explore the homologies of their unusual floral structures, especially the corona of Barbacenia and the corona-like appendages and multiple stamens of some Vellozia species. All Velloziaceae have epigynous flowers. Some species of Vellozia are polyandrous, and stamen number can be variable within species. In Vellozia jolyi, there is a single stamen opposite each sepal and a stamen fascicle (of three secondary stamens) opposite each petal. Each stamen possesses a single vascular bundle, and these are united into a single aggregate bundle in proximal regions of the fascicle. Stamens mature centripetally within each fascicle. The coronal appendages of both genera are closely associated with the stamens, but they share some vasculature with the tepals and develop late in ontogeny. The coronal organs cannot readily be homologized with any of the typical floral organs, but they show partial homology with both tepals and stamens. They are most readily interpreted as a late elaboration of the region between the petals and stamens associated with epigyny and the hypanthium. © 2010 by The University of Chicago.

Entre a Amnésia e a Vontade de nada Esquecer: notas sobre regimes de historicidade e história oral

In this paper we intend to sketch a configuration of the research practices of the Research Group Oral History and Mathematics Education (GHOEM) and, in general terms, to explain some concepts and procedures in which these practices are founded. In order to do this, the expression Regimes of Historicity - meaning the different ways of articulating the notions of present, past and future - is initially mobilized. By this expression we are able to understand the emergence of the discourse that underpins a set of actions and theoretical frameworks for the research in Mathematics Education and more particularly, for the Historiography of Mathematics Education.
