1. Clusters ou Sistemas Locais de Produção: Mapeamento, Tipologia e Sugestões de Políticas
RESUMO Este trabalho se propõe a avançar ainda mais no desenvolvimento de uma metodologia para mapeamento, classificação e caracterização de Sistemas Locais de Produção (SPL) no Brasil. Tal esforço se justifica não apenas pela importância que esses sistemas vêm acumulando para a geração de empregos e bem-estar social, crescimento econômico, ex

3. Prevalence and distribution of Angiostrongylus cantonensis (Nematoda, Angiostrongylidae) in Achatina fulica (Mollusca, Gastropoda) in Baixada Santista, São Paulo, Brazil
ABSTRACT INTRODUCTION Angiostrongylus cantonensis is causes eosinophilic meningoencephalitis in humans. Worldwide expansion of this nematode is linked to the dispersion of their hosts. This study aimed to determine the prevalence of A. cantonensis infection in Achatina fulica in the nine municipalities that make up Baixada Santista, São Paulo, Brazil. MET

4. Analysis of signal processing techniques for optical 112 Gb/s DP-QPSK receivers with experimental data
This paper evaluates several signal processing techniques for optical dual-polarization quadrature phase-shift keying (DP-QPSK) coherent receivers, using offline post-processing of experimental data. In addition to electronically separating the two polarization multiplexed signals, the investigated signal processing algorithms also compensate for chromatic d

5. PRODUÇÃO DE PIGMENTOS INORGÂNICOS A BASE DE ZrSiO4 COM INCORPORAÇÃO DE PASTA ELETROLÍTICA DE PILHAS / PREPARATION OF INORGANIC PIGMENTS BASED ON THE ZrSiO4 OXIDE FROM A MIXTURE OF AN ELECTROLYTIC-PASTE WASTE OF ALKALINE BATTERIES AND ZrSiO4
Throughout the times, new pigment systems have been gradually developed. In the nowadays, the development of ceramic pigments represents a part of the Materials Science, where there is a lack of concepts, roles and strategies, which in goal allows the developing of new rotes of preparing or pigments, in both scientific and technological areas. This work deal

6. DispersÃo de sementes por formigas na floresta AtlÃntica nordestina
O objetivo geral desse trabalho foi descrever a dispersÃo de sementes por formigas em remanescentes de floresta AtlÃntica nordestina, e testou algumas hipÃteses a respeito das vantagens obtidas pelas plantas atravÃs da dispersÃo por formigas. O trabalho foi realizado em dois fragmentos florestais (30 e 3.500 ha) da Usina Serra Grande, AL, entre agosto d

7. Judiciário e política regulatória: um estudo de caso sobre o papel das cortes e dos juízes na regulação do setor de telecomunicações
Courts and judges have acted as negative or positive implementers of public policies, justifying the consolidation of an agenda of research around Judiciary. Based on the theoretical presupposition of the neo-institutionalist approach that the regulatory results depend on the institutional endowment of countries, including justice system institutions, this d

8. Stress induction of Bm1 RNA in silkworm larvae: SINEs, an unusual class of stress genes
This study surveys the induction of RNA polymerase III (Pol III)–directed expression of short interspersed element (SINE) transcripts by various stresses in an animal model, silkworm larvae. Sublethal heat shock and exposure to several toxic compounds increase the level of Bm1 RNA, the silkworm SINE transcript, while also transiently increasing expression

9. Regulated bidirectional motility of melanophore pigment granules along microtubules in vitro
Although many types of membrane-bound organelles rely upon microtubule-based transport for their proper placement within the cytoplasm, the molecular mechanisms that regulate intracellular motility remain largely unknown. To address this problem, we have studied the microtubule-dependent dispersion and aggregation of pigment granules from an immortalized Xen

10. Botanical ratchets
Ratcheting surfaces are a common motif in nature and appear in plant awns and grasses. They are known to proffer selective advantages for seed dispersion and burial. In two simple model experiments, we show that these anisotropically toothed surfaces naturally serve as motion rectifiers and generically move in a unidirectional manner, when subjected to tempo

11. Disruption of the Golgi apparatus by brefeldin A blocks cell polarization and inhibits directed cell migration.
The role of the Golgi apparatus in the motile activity of fibroblasts was examined with brefeldin A (BFA), which disrupts the Golgi apparatus in a variety of cells. Upon incubation with BFA, Swiss mouse 3T3 fibroblasts lost their typical polarized morphology, in which the leading edge is characterized by intensive lamellipodia formation. BFA affected cell as

12. Structure and serological specificity of the K13-antigenic polysaccharide (K13 antigen) of urinary tract-infective Escherichia coli.
The primary structure of the K13-antigenic polysaccharide (K13 antigen) of Escherichia coli O6:K13:H1 was elucidated by composition, periodate oxidation, Smith degradation, and methylation analysis. The polysaccharide consists of a repeating sequence of 3-linked ribofuranose and 7-linked 3-deoxymannooctulosonic acid (KDO). About 50% of the KDO residues are O
