1. Evaluation of the antioxidant potential of Copaifera multijuga in Ehrlich tumor-bearing mice
RESUMO Copaifera multijuga, ou copaíba, é utilizada popularmente como chá para o tratamento de diversas afecções, o que se deve à presença de substâncias antioxidantes em sua composição, que protegem as células contra danos causados pelos radicais livres. O óleo-resina da árvore é usado como antiinflamatório e antitumoral. O presente estudo av

2. Development of self-nanoemulsifying tablet (SNET) for bioavailability enhancement of sertraline
Abstract The purpose of the study was to combine the advantages of self-nanoemulsifying drug delivery systems and tablets as a conventional dosage form. Self-nanoemulsifying drug delivery system (SNEDDS) was prepared to enhance the solubility and thus oral bioavailability of sertraline. Aqueous titration method was used to prepare the liquid SNEDDS; ternary

3. Modification of palm oil crystallization by phytosterol addition as a tool for structuring a low saturated lipid blend
Abstract Fat structural modifications promoted by phytosterol addition ( a hypocholesterolemic component ( to palm oil and a mixture of palm oil and canola oilwere evaluated in order to develop fats with reduced saturated fatty acids. Palm oil added with free or esterified phytosterols was investigated in terms of triacylglycerol composition, microstructure,

4. Caracterização do módulo elástico por espectroscopia mecânica da liga Ti-13Nb-13Zr
In the present time the titanium and their alloys are begin widely studied in the field of biomaterials because of its suitable mechanical properties such as low elastic modulus, excellent corrosion resistance and high biocompatibility. Recent studies are being focused on alloys free of toxic elements as Al and V, which are contained in the alloy Ti-6Al-4V t

5. TORNADO: an automated pipeline for de novo hybrid genome assembly based on free software packages for sanger and next generation sequencing technologies (NGS).
Next generation sequence technologies (NGS) made possible to sequence entirely genomes in a fast way and low cost, from unicellular to complex organisms, like plants and mammals. These sequences can be assembled (i ) using a reference genome or by some de novo bioinformatics method, such as Velvet, SOAPDenovo, Edena, ABYSS, GS Assembler 454, Mira and ZORRO.

6. A reliable procedure to predict salt precipitation in pure phases
This article proposes a new procedure to compute solid-liquid equilibrium in electrolyte systems that may form pure solid phases at a given temperature, pressure, and global composition. The procedure combines three sub-procedures: phase stability test, minimization of the Gibbs free energy with a stoichiometric formulation of the salt-forming reactions to c

7. Otimização de topologia de estruturas e componentes / Topology optimizatin of sctructures and components
Topology optimization (TO) is an optimization technique that aims to help the designer in the phase of structural conception, seeking a better distribution of one fixed amount of material in a extended design domain. It combines a method of structural analysis with a mathematical programming (MP) algorithm. In this work, structural analysis is done by Finite

11. Nanoparticle self-assembly using patterns formed by dewetting / Auto-organização de nanoparticulas utilizando padrões formados por transição de molhabilidade
In this work, we study an original method to promote self-assembly of gold and silica nanoparticles using patterns formed by dewetting of aqueous solutions of poly (N-isopropylacrylamide) (PNIPAM) and sodium dodecylsulfate (SDS). Dewetting is a process where the free surface of an initially stable thin liquid film becomes unstable and deforms to engender rup

12. Synthesis and Structural Analysis of new Coordination Polymer and molecular compounds of Phosphinatos Metals. / SÍNTESE E ANÁLISE ESTRUTURAL DE NOVOS POLÍMEROS DE COORDENAÇÃO E COMPOSTOS MOLECULARES DE FOSFINATOS METÁLICOS
In this work, the structures of coordination polymers and molecular compounds Cu(II), Hg(II), Pb(II) and Cd(II) with phenylphosphinate or diphenylphosphinate ligands were determined and are discussed. The reaction of phenylphosphinic or diphenylphosphinic acid with copper(II) acetate hydrate produces respectively aquaphenylphosphinate copper(II) or quadiphen
