  Projeto FAPESP-Birmingham - Nanotoxicity testing and informatics: harmonization of methodologies for environmental nanosafety and regulation, Descrição: The main goal of this CNPEM-University of Birmingham joint project is to promote a Brazil-UK cooperation towards international harmonization of methodologies for nanotoxicity testing and regulation. We will explore an informatics approach and integrate the experimental results obtained in this FAPESP-Birmingham project into the NanoCommons H2020 platform. The approach proposed in this joint research project would thus support reduced costs of nanosafety research by removing the need for extensive laboratory and toxicity testing, and supporting the scientific information quality control contributing to future harmonized regulations between Brazil and Europe toward safe and responsible nanotechnology innovations. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Carlos Alberto Pérez - Integrante / MARTINEZ, DIEGO STÉFANI TEODORO - Coordenador / Iseult Lynch - Integrante., Financiador(es): Fundação de Amparo à Pesquisa do Estado de São Paulo - Cooperação.

  Desenvolvimento de procedimentos de análise de imagens para avaliar caracterísitcas físicas, químicas e fisiológicas de sementes e plântulas, Descrição: A visão computacional e procedimentos não destrutivos são altamente desejáveis para a avaliação de características físicas, químicas e metabólicas de sementes e plântulas. Além de proporcionarem rapidez e precisão na obtenção de resultados, as avaliações podem ser realizadas em sementes e/ou plântulas individuais o que aumenta a eficiência para seleção de sementes com elevado potencial fisiológico. Dentre as técnicas que necessitam da atenção da pesquisa e possuem grande adoção por agências ligadas à produção de sementes podem ser citadas: (i) o desenvolvimento de software para avaliação do vigor de lotes de sementes e (ii) o aprimoramento de técnicas não invasivas capazes de produzir imagens internas de sementes e plântulas relacionadas com características físicas, químicas e metabólicas para diagnosticar problemas associados com perda do potencial fisiológico das sementes. Um dos métodos mais eficientes para avaliação do vigor de sementes é a determinação da velocidade e uniformidade de desenvolvimento de plântulas, pois está diretamente relacionado com a capacidade de suprimento de reservas dos tecidos de armazenamento para o eixo embrionário. O vigor da semente também pode apresentar influência sobre a eficiência de aproveitamento de micronutrientes aplicados via tratamento de sementes e a avaliação da dinâmica de absorção e assimilação desses elementos pelas sementes e plântulas utilizando técnicas não destrutivas são fundamentais para compreender o comportamento de lotes de sementes de alto e baixo vigor. As propostas desse projeto são: (i) desenvolver softwares específicos para avaliação do vigor de sementes de milho, trigo, arroz, melão, cenoura e cebola, com base em imagens digitalizadas de plântulas e (ii) avaliar o metabolismo de absorção de micronutrientes em sementes e plântulas de soja com diferentes níveis de vigor por meio da espectroscopia de fluorescência (XRF) e de absorção (XAS) de raios X. Paralelamente, serão realizados experimentos exploratórios visando otimizar protocolos específicos de ressonância magnética para avaliação in vivo do metabolismo de carboidratos nas plântulas de soja com os diferentes níveis de vigor. Os conhecimentos gerados no projeto poderão aumentar a eficiência na avaliação do potencial fisiológico de sementes comercializadas e a maximização do retorno econômico.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Especialização: (1) / Mestrado acadêmico: (1) . , Integrantes: Carlos Alberto Pérez - Integrante / Hudson Carvalho - Integrante / Francisco Guilhien Gomes Junior - Coordenador / Agide Gimenez Marassi - Integrante / Alberto Tannús - Integrante / Fernando Fernandes Paiva - Integrante / Julio Marcos Filho - Integrante / Silvio Moure Cicero - Integrante., Financiador(es): Fundação de Amparo à Pesquisa do Estado de São Paulo - Auxílio financeiro.

  MUDANÇAS CLIMÁTICAS E IMPACTOS AMBIENTAIS EM ÁREAS ALAGADAS (WETLANDS) DO PANTANAL (BRASIL): QUANTIFICAÇÃO, FATORES DE CONTROLE E PREVISÃO EM LONGO PRAZO, Descrição: As áreas alagadas (wetlands) têm papel fundamental no controle de fatores que podem influenciar ou serem influenciados por mudanças climáticas e ambientais O projeto apresentado será desenvolvido na Nhecolândia (MS), região caracterizada por um sistema de lagoas cujas águas variam de doce a hipersalina. Trata-se de uma pesquisa multi e interdisciplinar cujo desafio científico é elucidar o funcionamento geoquímico e biogeoquímico dessa região, transferir os conhecimentos adquiridos para a elaboração de balanços regionais dos fluxos de gases de efeito estufa (GEE), e compreender os processos de disponibilização do arsênio (As) para as águas, considerando a influência de fatores ambientais, em particular, das mudanças climáticas. O projeto está estruturado em quatro ações cujos objetivos específicos são : (i) identificar os processos que controlam os funcionamentos biogeoquímicos das lagoas e avaliar suas consequências nos ciclos do C e do N, nas emissões de GEE e na distribuição e especiação do As na paisagem ; (ii) verificar a evolução dos solos ao redor das lagoas, para compreender o funcionamento do sistema solo-água; (iii) desenvolver um modelo numérico do funcionamento hidrológico e hidroquímico das lagoas, para predizer a evolução do sistema face aos estresses ambientais ; (iv) verificar o potencial de utilização dos dados de sensoriamento remoto para identificar feições espectrais e topográficas que permitam associar as variáveis que poderiam estar relacionadas as emissões de GEE e sua extrapolação para a escala regional. Os resultados obtidos poderão fornecer subsídios científicos para elaboração de políticas públicas para o gerenciamento sustentável do Pantanal. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Carlos Alberto Pérez - Integrante / Adolpho José Melfi - Coordenador / Anne Helene Fostier - Integrante / Célia Regina Montes - Integrante / Debora Marcondes Bastos Pereira - Integrante / Janaina Braga do Carmo - Integrante / Marli de Fatima Fiore - Integrante., Financiador(es): Fundação de Amparo à Pesquisa do Estado de São Paulo - Auxílio financeiro.

  Construção de uma linha dedicada de luz exclusiva para Fluorescência de Raios-X no Laboratório Nacional de Luz Sincrotron, LNLS, Campinas, SP, Brasil, Descrição: The X-Ray Fluorescence (XRF) beamline, constructed at the Brazilian National Synchrotron Radiation Laboratory, has been operating for the external users since August of 1998. The synchrotron source for this beamline is the D09B (15) dipole magnet of the LNLS storage ring. Two main experimental set-ups are mounted at the XRF beam line. One consists of a high vacuum chamber adapted to carry out experiments in grazing excitation conditions. This allows chemical trace element analysis on several samples, mainly coming from environmental and biological sciences. Another set-up consists of an experimental station, operated in air, in which x-ray fluorescence analysis with spatial resolution can be done. This station is equipped with a fine conical capillary, capable to achieve 20 microns spatial resolution, and with an optical microscope in order to select the region of interest on the sample surface.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (0) / Especialização: (0) / Mestrado acadêmico: (0) / Mestrado profissional: (0) / Doutorado: (2) . , Integrantes: Carlos Alberto Pérez - Integrante / Marcelo Rubio - Integrante / Maria Izabel Silveira Bueno - Coordenador / Ivo Raimundo - Integrante / Jarbas Rohwedder - Integrante / R A Barrea - Integrante / R T Lopes - Integrante / Silvana Moreira - Integrante., Financiador(es): Fundação de Amparo à Pesquisa do Estado de São Paulo - Auxílio financeiro., Número de produções C, T & A: 13
