The aim of this study was to assess the effect of N(2)-fixing and P-solubilizing bacteria during maturation of vermicompost on phosphorus availability. A bacterial suspension containing Burkholderia silvatlantica, Burkholderia spp. and Herbaspirillum seropedicae was applied at the initial stage of vermicomposting. At the end of the incubation time (120days), the nitrogen content had increased by18% compared to uninoculated vermicompost. Water-soluble P was 106% higher in inoculated vermicompost while resin-extractable P increased during the initial vermicomposting stage and was 21% higher at 60days, but was the same in inoculated and uninoculated mature compost. The activity of acid phosphatase was 43% higher in inoculated than uninoculated vermicompost. These data suggest that the introduction of the mixed culture had beneficial effects on vermicompost maturation.

The tropical tree Bixa orellana L. produces a range of secondary metabolites which biochemical and molecular biosynthesis basis are not well understood. In this work we have characterized a set of ESTs from a non-normalized cDNA library of B. orellana seeds to obtain information about the main developmental and metabolic processes taking place in developing seeds and their associated genes. After sequencing a set of randomly selected clones, most of the sequences were assigned with putative functions based on similarity, GO annotations and protein domains. The most abundant transcripts encoded proteins associated with cell wall (prolyl 4-hydroxylase), fatty acid (acyl carrier protein), and hormone/flavonoid (2OG-Fe oxygenase) synthesis, germination (MADS FLC-like protein) and embryo development (AP2/ERF transcription factor) regulation, photosynthesis (chlorophyll a-b binding protein), cell elongation (MAP65-1a), and stress responses (metallothionein- and thaumatin-like proteins). Enzymes were assigned to 16 different metabolic pathways related to both primary and secondary metabolisms. Characterization of two candidate genes of the bixin biosynthetic pathway, BoCCD and BoOMT, showed that they belong, respectively, to the carotenoid-cleavage dioxygenase 4 (CCD4) and caffeic acid O-methyltransferase (COMT) families, and are up-regulated during seed development. It indicates their involvement in the synthesis of this commercially important carotenoid pigment in seeds of B. orellana. Most of the genes identified here are the first representatives of their gene families in B. orellana.

In this study, we report results of the detection and analysis of SSR markers derived of cacao-Moniliophthora perniciosa expressed sequence tags (ESTs) in relation to cacao resistance to witches' broom disease (WBD), and we compare the polymorphism of those ESTs (EST-simple sequence repeat (SSR)) with classical neutral SSR markers. A total of 3,487 ESTs was used in this investigation. SSRs were identified in 430 sequences: 277 from the resistant genotype TSH 1188 and 153 from the susceptible one Catongo, totalizing 505 EST-SSRs with three types of motifs: dinucleotides (72.1%), trinucleotides (27.3%), and tetranucleotides (0.6%). EST-SSRs were classified into 16 main categories; most of the EST-SSRs belonged to "Unknown function" and "No homology" categories (45.82%). A high frequency of SSRs was found in the 5'UTR and in the ORF (about 27%) and a low frequency was observed in the 3'UTR (about 8%). Forty-nine EST-SSR primers were designed and evaluated in 21 cacao accessions, 12 revealed polymorphism, having 47 alleles in total, with an average of 3.92 alleles per locus. On the other hand, the 11 genomic SSR markers revealed a total of 47 alleles, with an average of 5.22 alleles per locus. The Communicated by J.

Resumo-A codificação wavelet de canal objetiva reduzir efeitos deletérios de canal de comunicação sem fio sobre um sinal transmitido e emprega comumente uma decodificação símbolo a símbolo. Este trabalho investiga o emprego de decodificador de Viterbi para códigos wavelet e compara, em termos da taxa de erro de bits, o desempenho do sistema operando sobre canal com desvanecimento Rayleigh, quando aplicada a decodificação de Viterbi, em relação à decodificação tradicional. Os resultados de simulação demonstraram que a decodificação de sequência proporciona desempenho superior à decodificação símbolo a símbolo.

Abstract. This paper propose a real-time vision framework for mobile robotics and describes the current implementation. The pipeline structure further reduces latency and allows a paralleled hardware implementation. A dedicated hardware vision sensor was developed in order to take advantage of the proposed architecture. The real-time characteristics and hardware partial implementation, coupled with low energy consumption address typical autonomous systems applications. A characterization of the implemented system in the Robocup scenario, during competition matches, is presented.

A Organização Mundial de Saúde (OMS), em 1946 definiu a saúde como "um estado de completo bem-estar físico, mental e social, e não somente ausência de afecções e enfermidades" e, portanto, a saúde pública está intimamente ligada nesta definição, uma vez que é a grande responsável por associar todo o conjunto de medidas que são executadas pelo Estado, para garantir o bem-estar físico, mental e social de toda a população brasileira.Nesta perspectiva, é importante que profissionais da saúde tenham a compreensão do valor da interdisciplinaridade e interprofissionalidade na solução dos problemas de ordem de saúde pública, associando as mais diversas áreas de conhecimento na intenção de produção e aperfeiçoamento do conhecimento, além da resolução ou até mesmo cura das doenças, e com consequente melhora da qualidade de vida da população.Sendo assim, os profissionais da saúde necessitam de constante atualização em relação ao conhecimento científico que está sendo gerado no Brasil, complementando a formação de um profissional ou estudante, através da amplitude e domínio do conhecimento que é gerado a partir dos mais variados temas que compõem o campo da saúde pública brasileira. À vista disso, o volume 1 de 2022, traz a proposta de uma educação continuada para profissionais e estudantes, representando boa parte da demanda do conteúdo científico gerado no Brasil através de artigos técnicos e científicos, com o tema "SAÚDE PÚBLICA NO BRASIL: UM PANORAMA ATUAL".Em nossos livros selecionamos um dos capítulos para premiação como forma de incentivo para os autores, e entre os excelentes trabalhos selecionados para compor este livro, o premiado foi o capítulo 15, intitulado "ESCOMBROS DA SAÚDE MENTAL: ALGO

Stochastic approaches have become increasingly common in robotics. Techniques that consider the uncertainties of sensors and models are being adopted in various applications. In this context, state estimation techniques play an important role, since they deal directly with these uncertainties, making systems more reliable. This paper aims to survey the state of the art of application of stochastic approaches in robotics in the context of the work developed in Brazil. At the end, the main applications that use stochastic approaches in robotics are summarized, and the main tools used in each case are suggested. Moreover, the main outstanding issues, which should be the focus of further research, are indicated. Thus, this paper is intended to be a useful tool for new researchers in this booming research area.
