25. Caracterização do material particulado inalavel (MP10) na atmosfera de Paulinia e região
The present work evaluated the particulate matter (PM10) emission contributions of the Replan catalytic cracking plant in the inhalable particulate matter (PM10) of the region affected by the refinery. To separate the contribution of the source under investigation from other sources that contribute to the particulate matter in suspension, the receptor model

26. Síntese e espectroscopia de sistemas envolvendo tungstatos e íons de terras raras / Synthesis and spectroscopy of system envolving tungstates and rare earth ions
The studies about the photoluminescent properties of the rare earth tungstates Eu2(WO4)3 and Gd2(WO4)3:RE3+ (RE3+ = Eu, Sm and Tb) obtained via three different methods of preparation were reported: i) ceramic method, which is the older one and uses high temperatures (>1000 ºC) and long periods of heating, with the physical mixture of the reagents in the pow

27. Physical, chemical, mineralogical and morphological characterization of a soil series in Lins/sp. / Caracterização física, química, mineralógica e morfológica de uma sequência de solos em Lins/SP.
Este trabalho tem como objetivo a caracterização de um sistema de solos, evidenciando os parâmetros que possam esclarecer sua dinâmica e contribuir para a definição de critérios que possam determinar a aptidão destes solos como receptores de efluentes. Trata-se de uma área experimental de estudos, contígua à Estação de Tratamento de Esgoto do mu

28. Preparação e caracterização de nanocompositos organo-inorganicos envolvendo fosfatos de metais tetravalentes e polimeros condutores
Acid cerium (IV) phosphates (CeP) were prepared and the influence of synthetical conditions, such as reagents PO4/Ce molar ratios, temperature and reaction time, on the structural and morphological properties were studied. Several techniques like X-ray diffraction, infrared, Raman and P nuclear magnetic resonance spectroscopies were used to follow the struct

29. Compression Wood-Responsive Proteins in Developing Xylem of Maritime Pine (Pinus pinaster Ait.)12
When a conifer shoot is displaced from its vertical position, compression wood (CW) is formed on the under side and can eventually return the shoot to its original position. Changes in cell wall structure and chemistry associated with CW are likely to result from differential gene/protein expression. Two-dimensional polyacrylamide gel electrophoresis of diff

30. Immunoisolation and partial characterization of endothelial plasmalemmal vesicles (caveolae).
Plasmalemmal vesicles (PVs) or caveolae are plasma membrane invaginations and associated vesicles of regular size and shape found in most mammalian cell types. They are particularly numerous in the continuous endothelium of certain microvascular beds (e.g., heart, lung, and muscles) in which they have been identified as transcytotic vesicular carriers. Their
