Resumo IPEN-doc 14443 INAA: A link between past and present in retrieving of peoples identities2007 - MUNITA, C.S.; SANTOS, J.O.; TOYOTA, R.G.; NUNES, K.P.; OLIVEIRA, P.M.S.; FERREIRA, D.S.Artigo IPEN-doc 12138 The utilization of trace chemical composition to correlate ceramics with clay deposits2007 - NUNES, KELLY P.; TOYOTA, ROSIMEIRI G.; MUNITA, CASIMIRO S.; OLIVEIRA, PAULO M.S.; NEVES, EDUARDO G.; SOARES, EMILIO A.A.In this work, 22 clay samples near Hatahara and Açutuba archaeological sites, and 135 ceramic samples were analyzed by means of Instrumental Neutron Activation Analysis. INAA is the most suitable technique because it does not require mineralization of samples and has high sensitivity, accuracy and precision. The samples were irradiated in IEA-R1 reactor at IPEN-CNEN-SP at thermal neutron flux of 8,92x10 12 cm -2 s -1 during one hour. The elementary concentration results were studied using multivariate statistical methods. The compositions group classification was done through cluster analysis and the similarity/dissimilarity among the samples was studied by means of discriminant analysis.Artigo IPEN-doc 15740 Estudo preliminar da composicao mineralogica de ceramicas Marajoara por difracao de raios X2010 - NUNES, KELLY P.; TOYOTA, ROSIMEIRI G.; MUNITA, CASIMIRO S.; CARVALHO, FLAVIO M.S.; NEVES, EDUARDO G.; DEMARTINI, CELIA C.Artigo IPEN-doc 15587 Difratometria de raios-x aplicada ao estudo preliminar da composicao mineralogica de ceramicas arqueologicas Marajoara2010 - NUNES, KELLY P.; TOYOTA, ROSIMEIRI G.; MUNITA, CASIMIRO S.; CARVALHO, FLAVIO M.S.; NEVES, EDUARDO G.; DEMARTINI, CELIA C.Artigo IPEN-doc 17641 Study of the firing temperature of Marajoara archaeological ceramics by electron paramagnetic resonance associated to INAA data2011 - NUNES, KELLY P.; TOYOTA, ROSIMEIRI G.; MUNITA, CASIMIRO S.; SCHAAN, DENISE P.; OLIVEIRA, PAULO M.S.; NEVES, EDUARDO G.; DEMARTINI, CELIA; BAFFA, OSWALDO; OLIVEIRA, LUIS C.; BRUNELLO, CARLOS A.Artigo IPEN-doc 19528 Preliminary compositional evidence of provenance of ceramics from Hatahara Archaeological Site, Central Amazonia2013 - NUNES, K.P.; TOYOTA, R.G.; OLIVEIRA, P.M.S.; NEVES, E.G.; SOARES, E.A.A.; MUNITA, C.S.Artigo IPEN-doc 18344 Study of the firing temperature of Marajoara archaeological ceramics by EPR associated to INAA data2012 - NUNES, KELLY P.; MUNITA, CASIMIRO S.; TOYOTA, ROSIMEIRI G.; OLIVEIRA, PAULO T.M.; CANO, NILO F.; SCHAAN, DENISE; BAFFA, OSWALDO; OLIVEIRA, LUIZ C.; BRUNELLO, CARLOS A.; NEVES, EDUARDO G.; DEMARTINI, CELIA C.
