1. Toward a phylogenetic reclassification of the subfamily Ambavioideae (Annonaceae): establishment of a new subfamily and a new tribe
ABSTRACT A molecular phylogeny of the subfamily Ambavioideae (Annonaceae) was reconstructed using up to eight plastid DNA regions (matK, ndhF, and rbcL exons; trnL intron; atpB-rbcL, psbA-trnH, trnL-trnF, and trnS-trnG intergenic spacers). The results indicate that the subfamily is not monophyletic, with the monotypic genus Meiocarpidium resolved as the seco

2. Pollen types of Sapindaceae from Brazilian forest fragments: apertural variation
ABSTRACT Morphological variations in angiosperm pollen grains may aid in the differentiation of families, genera and species. Sapindaceae pollen morphology holds promise for the recognition of taxa of this cosmopolitan family, which is well distributed in tropical regions and possesses great morphological diversity. This study presents the pollen morphology

3. Pollen morphology of the Brazilian species of Bernardia Houst. ex Mill. and Tragia L. (Euphorbiaceae, Acalyphoideae)
ABSTRACT Bernardia and Tragia are the largest genera of the tribes Bernardieae and Plukenetieae (Euphorbiaceae,), with 68 and 125 species, respectively. Very few palynological studies have focused specifically on these genera in spite of the great pollen diversity observed in the family. The present study analyzed the pollen morphology of the Brazilian speci

4. Formação de professores de Física e interdisciplinaridade: episódios de refração de políticas em narrativas de reforma curricular
Resumo: A presente pesquisa focaliza o processo de reestruturação dos cursos de Licenciatura em Física da Universidade Estadual de Campinas (Unicamp) ocorrido entre 2001 e 2005, buscando compreender como a noção de interdisciplinaridade presente nas Diretrizes Curriculares Nacionais de Formação de Professores se modifica no caminho entre políticas cu

5. Spores of Plagiochila (Dumort.) Dumort.: the taxonomic relevance of morphology and ultrastructure
ABSTRACT Plagiochilaceae is a family of leafy liverworts that are distributed worldwide. It is of great importance due to its taxonomic and ecological implications among bryophytes. Most species of the family belong to the genus Plagiochila, but there is no consensus regarding its infrageneric circumscription. There have been few palynological studies involv

6. Pollen morphology of Brazilian species of Verbesina L. (Heliantheae - Asteraceae)
Abstract There are nine species of the plant genus Verbesina in Brazil, which are distributed in the Northeast, Center-West, Southeast and South regions of the country. The objective of the present study was to describe the pollinic morphology of eight of these species to better characterize them and evaluate potential species-level taxonomic characters. Ace

7. Pollen diversity in selected species of the tribe Chironieae (Gentianaceae Juss.) that occur in the Atlantic Forest, Brazil
ABSTRACT Based on molecular data, the tribe Chironieae (Gentianaceae) is divided into three subtribes. This study aims to describe the pollen morphology of representatives of two of the three subtribes that occur in the Atlantic Forest in order to contribute to a better understanding of the palynology of these taxa and to clarify the taxonomy of the family:

8. Pollen morphology and its taxonomic significance in the genus Bomarea Mirb. (Alstroemeriaceae) - II. Subgenus Bomarea
Pollen morphology of 52 species (out of c. 79) of the Bomarea subgenus Bomarea was examined using light microscopy and scanning electron microscopy (SEM), or using SEM alone. The studied species of Bomarea were stenopalynous, characterized by large, oblate, monosulcate monads with reticulate exine sculpture in most species. Wide variation was observed in qua

9. Pollen morphology and its taxonomic significance in the genus Bomarea Mirb. (Alstroemeriaceae) - I. Subgenera Baccata, Sphaerine, and Wichuraea
ABSTRACTPollen morphology of 24 of the 33 species of three Bomareasubgenera, Baccata, Sphaerine, andWichuraea, was examined by light microscopy (LM) and scanning electron microscopy (SEM), or SEM alone. The studied species ofBomarea were stenopalynous, characterized by large, monosulcate monads with reticulate exine sculpture in most species. Opercula-like s

11. A questão das substâncias corporais em Leibniz / Question of substances bodies in Leibniz
Our main goal was to elucidate the role and ontological status of bodies of living beings in Leibnizianism. To do this, we start from Cartesian ontology which transforms bodies in substances whose essence is the extension comprehended geometrically. Then, we analyze the critics made by Leibniz to this ontology as well as the new ontology of forces and monads

12. Structuring general and complete quantum computations in Haskell : the arrows approach / Estruturando computaçõoes quânticas gerais e completas em Haskell : abordagem das setas
Computaçãao quântica pode ser entendida como transformação da informação codificada no estado de um sistema físico quântico. A idéia básica da computação quântica é codificar dados utilizando bits quânticos (qubits). Diferentemente do bit clássico, o qubit pode existir em uma superposição dos seus estados básicos permitindo o “paralelis
