1. Characterization and mechanical properties of one-part geopolymer based on a pure metakaolin
Abstract Geopolymers are amorphous silicate polymers that have been extensively studied due to their applications, scientific and technical relevance, and their potential as cement in substitution to Portland. Much of the focus has been in the use of precursors and aggregates that are rarely pure and homogeneous with the use of tailings being very common. Th

4. NOW THE SNEAKING SERPENT WALKS: DIABOLIC AS A CREATION FORCE IN THE MARRIAGE OF HEAVEN AND HELL, BY WILLIAM BLAKE
Abstract In The Marriage of Heaven and Hell (1790-1793), William Blake traces a flying route through the Universe. His muse, the “sneaking serpent”, supports the concept that ‘diabolic’ is not a synonym of ‘evil’ – nevertheless, it is an active springing of Energy, as, according to the poet, every existence is holy. This study understands the p

5. ELECTRICAL NOISES REDUCTION IN NANOPORES EXPERIMENTS BASED ON CONSENSUS FILTER
Nanopore has developed into an indispensable tool for single molecules experiments, where useful information about the characteristics of DNA/RNA can be obtained from the flowing of ionic current elicited by individual molecules as they traverse a single nanometer-scale aperture. However, due to the relatively high background current noise and low measuremen

6. Optimization of sunflower oil bleaching parameters: using Response Surface Methodology (RSM)
Abstract Bleaching is an important part of the oil refining process, in which pigments, impurities, traces of metals, and oxidative-molecular components of oils are removed. In this regard, the optimization of bleaching conditions can be effective to increase oil quality. In this study, de-gummed and neutralized sunflower oil was bleached at 80, 90, 100, 110

11. Morphology, Crystalline Structure and Chemical Composition Of MAO Treated Ti-15Zr-Mo Surfaces Enriched with Bioactive Ions
In this study, MAO treatment was used to enrich, with bioactive Ca, Mg and P atoms, as-casted and heat-treated Ti-15Zr-xMo (x = 0, 5, 10 and 15 wt%) alloys, for potential use as advanced metallic biomaterials. The chemical composition of the surface was evaluated by EDS and XPS measurements. The morphology and microstructure was analyzed by OM and SEM images

12. O (RE)CONHECIMENTO DA SÓCIO-HISTÓRIA NAS CAPACIDADES DE SIGNIFICAÇÃO: CONCEITOS NECESSÁRIOS PARA OPERACIONALIZAÇÃO DE LINGUAGEM E DIDATIZAÇÃO DE GÊNEROS
RESUMO O presente artigo visa discutir a respeito da operação de linguagem denominada (re)conhecimento da sócio-história do gênero, apresentada por Cristovão e Stutz (2011) no quadro das capacidades de significação. Nesse sentido, demonstramos os traços textuais utilizados para analisar essa operação de nível macrocontextual, relacionada com a at
