Neste estudo analisar-se-ão as obras produzidas por alguns artistas plásticos contemporâneos a viverem na Guiné-Bissau e Diáspora guineense com particular atenção dada aos géneros artísticos eles usados assim como à sua mensagem sociopolítica. Após uma breve introdução às diferentes formas de arte plástica oriundas da guineense, concentrar-nos-emos em para desconstruirmos produção artística e, ...

The commonly known Pimenta longa is a commercially valuable natural resource found wild in Acre, Brazil. Specifically, three Piperaceae species with contested taxonomic status were studied, Piper hispidinervum, Piper aduncum, and Piper hispidum, to assesses the interand intra-specific genetic relationship of 49 Piper genotypes kept in the Pimenta longa germplasm collection at Embrapa Acre, usin...

It is known that, in vitro, PIPER (N,N'-bis [2-(1-piperidino)ethyl]-3,4,9,10-tetracarboxylic diimide) induces the formation of the Hoogsteen quadruplex structure in telomere DNA, thus inhibiting the polymerisation of telomeric repeats. Since the action of PIPER in vivo has been scarcely investigated, this study was addressed to gain some insight into the effects of this drug on cultured HeLa ce...

Human body models (HBMs) have the potential to provide significant insights into the pediatric response to impact. This study describes a scalable/posable approach to perform child accident reconstructions using the Position and Personalize Advanced Human Body Models for Injury Prediction (PIPER) scalable child HBM of different ages and in different positions obtained by the PIPER tool. Overall...

In Flora Costaricensis, William Burger of the Field Museum in Chicago considered eight of the Piper species that occur in Costa Rica to make up the P. obliquum complex, and six additional species to be closely allied to it (Fig. 9.1; Burger 1971). Piper calcariformis, an additional species assignable to the P. obliquum complex, was later described by Tebbs (1989). Although Burger did not apply ...

The genus Piper is an important component of tropical forests worldwide. Many Piper species have been reported as self-compatible (Figueiredo & Sazima 2000), and many have the ability to reproduce asexually, forming clonal aggregations (Grieg 1993). Furthermore, the main dispersers of Piper (bats) transport whole infructescences to feeding roosts (Fleming & Heithaus 1981), tending to disperse c...
