Interfaces entre o PNAE, capital social e o fortalecimento da agricultura familiar no quilombo do Pacoval/Alenquer-Pará

A aludida pesquisa teve como base a operacionalização do Programa Nacional de Alimentação Escolar (PNAE) na comunidade remanescente de quilombo do Pacoval em Alenquer/Pará. Analisou-se as interfaces do capital social, a agricultura familiar e a política pública, utilizando a metodologia qualitativa e quantitativa, com procedimentos de entrevistas semiestruturada com diversos atores. Concluímos que existe pouca eficiência na execução do programa, que perpassa pelo a) despreparo dos gestores públicos responsáveis; b) ausência de informações dos agricultores no tocante as exigências burocráticas e ausência de assistência técnica agronômica/gestão para os agricultores; e c) inadequação de um cardápio alimentar quilombola, associada a baixa participação dos agricultores familiares no programa. Em contraponto e buscando soluções, a estratégia interorganizacional puxada pela dianteira do capital social quilombola, vem possibilitando um curso de mudanças com a inserção dos agricultores familiares no PNAE de 2019, incrementando renda na economia local e garantindo alimentos de qualidade aos alunos das escolas do quilombo

A Taxonomically-informed Mass Spectrometry Search Tool for Microbial Metabolomics Data

MicrobeMASST, a taxonomically-informed mass spectrometry (MS) search tool, tackles limited microbial metabolite annotation in untargeted metabolomics experiments. Leveraging a curated database of >60,000 microbial monocultures, users can search known and unknown MS/MS spectra and link them to their respective microbial producers via MS/MS fragmentation patterns. Identification of microbial-derived metabolites and relative producers, without a priori knowledge, will vastly enhance the understanding of microorganisms’ role in ecology and human health

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
