Autor: Igor S. Flores, Marcos R. Monteiro, Mariana da S. Godinho, Glaucia Braz Alcantara, A.E. de Oliveira, Luciano M. Lião, Sônia M.C. Menezes

Publikováno v: Fuel. 99:40-44

The use of 1H NMR in combination with principal component analysis (PCA) is proposed, for the first time, to discriminate methyl biodiesel from different sources. Sixty-six samples, either pure or combined into binary blends of biodiesel from castor,

O Perfil da Carreira dos Docentes de Química da Rede de Ensino Pública do Estado de Goiás, Brasil: Uma Análise Multivariada

Autor: Mariana da S. Godinho, Anselmo E. de Oliveira, Deangelis Damasceno, Márlon Herbert Flora Barbosa Soares

Publikováno v: Educación Química. 21:246-253

En 1996 la Ley de Directrices y Bases de la Educacion (LDB) establecio que a partir de 2007 se permitiria ensenar en los bachilleratos publicos brasilenos solo a profesores graduados. Los bachilleratos del estado de Goias han encarado desde entonces

Autor: Mariana da S. Godinho, Raquel O. Pereira, Keysi de O. Ribeiro, Fernando Schimidt, Anselmo E. de Oliveira, Sérgio B. de Oliveira

Publikováno v: Química Nova, Vol 31, Iss 6, Pp 1485-1489 (2008)

This paper describes an approach for the colour-based classification of RGB (red-green-blue) images, acquired using a common scanner, of commercial carbonated soft drinks. Mean histograms of image colour channels were evaluated for the PCA classifica
