13. Valorization of agroindustrial solid residues and residues from biofuel production chains by thermochemical conversion: a review, citing Brazil as a case study
Besides high industrial development, Brazil is also an agribusiness country. Each year about 330 million metrics tons (Mg) of biomass residues are generated, requiring tremendous effort to develop biomass systems in which production, conversion and utilization of bio-based products are carried out efficiently and under environmentally sustainable conditions.

14. The influence of the industrial processing on the degradation of poly(hidroxybutyrate) - PHB
PHB was characterized after different industrial processes by Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR), Melt Flow Index (MFI), Complex Dielectric Relaxation (CDR) and Size Exclusion Chromatography (SEC). Some properties of PHB were investigated before and after processing, in order to understand how temperature

18. Correntes ancestrais: os pretos-velhos do Rosário / Ancestral chains: the pretos-velhos of the Rosario
Complex and abundant in its possibilities of conformation, umbanda trance has its borders established for some types of characters displaced from the historical experience and collective memory of Brazil. These categories organize sayings from their own enunciative perspectives, symbolically articulated positions potentially able to produce certain meanings.

19. Uso de espectrometria de massas e mobilidade iônica na caracterização de peptídeos provenientes de experimentos de ligação cruzada / Mass spectrometry and ion mobility in the characterization and of peptides from protein cross-linking experiments
There are several advantages associated with the use of mass spectrometry (MS) applied to structural studies of proteins, such as unlimited mass of target protein or protein complex, very low time and sample consumption, ease of manipulation and interpretation of the data obtained. In chemical cross-linking coupled to MS, bifunctional reagents (cross-linkers

21. The activity of a metronidazole analogue and its β-cyclodextrin complex against Trypanosoma cruzi
In this study we prepared an inclusion complex between an iodide analogue of metronidazole (MTZ-I) and cyclodextrin (CD) to develop a safer and more effective method of treating Trypanosoma cruzi infections. According to our results, MTZ-I and MTZ-I:β-CD were 10 times more active than MTZ, demonstrating that the presence of an iodine atom on the side chain

22. Blendas de poli(metacrilato de metila) e do elastômero saturado poli(acrilonitrila-g-(etileno-co-propileno-co-dieno-g-estireno) obitdas por polimerização in situ / Blends of poly(methyl methacrylate) and the saturated elastomer poly(acrylonitrile-g-(ethylene-co-propylene-co-diene)-g-styrene) prepared by in situ polymerization
In this work, blends of the poly(methyl methacrylate), PMMA, and the poly[acrylonitrile-g-(ethylene-co-propylene-co-diene)-g-styrene], AES, were prepared. AES is a complex mixture of poly(styrene-co-acrylonitrile), SAN, and poly(ethylene-copropylene-co-diene), EPDM, and the graft copolymer EPDM-g-SAN. Blends PMMA-AES were obtained by polymerization in situ,
