The potteries’ chemical fingerprints from Ijuí River, Ibicuí Mirim River, Vacacaí Mirim River and Jacuí River were identified. Interactions between sites from the Jacuí River, Vacacaí Mirim River and Ibicui Mirim River could have occurred because some samples from these sites are overlapping in a principal component analysis (PCA) graphic. The pottery provenance could be the same.Artigo IPEN-doc 02460 Determination of neutron fluence based on the measurement of isotopic variation of cadmium and gadolinium1984 - TOMIYOSHI, I.A.; IYER, S.S.; RODRIGUES, C.Artigo IPEN-doc 07563 Determination of neutron fluence using the plot of isotope variation of cadmium and gadolinium1998 - TOMIYOSHI, I.A.; IYER, S.S.; RODRIGUES, C.Artigo IPEN-doc 08265 Determination of trace amounts of rare earth elements in highly pure praseodymium oxide by double focusing inductively coupled plasma mass spectrometry and high-performance liquid chromatography2001 - PEDREIRA FILHO, W.R.; SARKIS, J.E.S.; RODRIGUES, C.; TOMIYOSHI, I.A.; QUEIROZ, C.A.S.; ABRAO, A.Artigo IPEN-doc 08604 Determination of trace amounts of rare earth elements in high pure lanthanum oxide by sector field inductively coupled plasma mass spectrometry (HR ICP-MS) and high-performance liquid chromatography (HPLC) techniques2002 - PEDREIRA FILHO, W.R.; SARKIS, J.E.S.; RODRIGUES, C.; TOMIYOSHI, I.A.; QUEIROZ, C.A.S.; ABRAO, A.Artigo IPEN-doc 09519 Determination of trace amounts of rare-earth elements in highly pure neodymium oxide by sector field inductively coupled plasma mass spectrometry (ICP-SFMS) and high-performance liquid chromatography (HPLC) techniques2003 - PEDREIRA FILHO, W.R.; SARKIS, J.E.S.; QUEIROZ, C.A.S.; RODRIGUES, C.; TOMIYOSHI, I.A.; ABRAO, A.
