1. Production of components with plaster residue and sodium citrate: physical, mechanical, rheological analysis
Resumo A indústria da construção civil, grande influenciadora no desenvolvimento econômico e social do país, é responsável por um grande consumo de matéria prima e produção de resíduos. O gesso, em especial, apresenta crescimento expressivo, sobretudo na região Nordeste, devido ao Pólo Gesseiro do Araripe. Considerando os graves problemas de seu

2. A New Approach for Severity Estimation of Transversal Cracks in Multi-layered Beams
Abstract Nowadays, the damage severity evaluation in mechanical structures is mostly performed by analyzing the natural frequency shift. The non-isotropic materials, as the multi-layered ones, are wide-spread in industrial applications, due to their interesting physic-mechanical properties. Thus, a deeper approach of multi-layered beams becomes an important

3. Comportamiento Tribológico y Microestructural en Recubrimientos Aplicados por GTAW y HVOF (Proceso Térmico de Espreado) y Usado en Recuperación de Aceros Grado Herramienta AISI/SAE D2
Abstract The Fe-Cr-Mo alloys are use in covers to protect the components that are under wear and corrosion. The high velocity thermo spray covering by HVOF (high velocity oxi-fuel) in Fe-Cr-Mo alloys has reported as a good result in projection fields for the steel tool grade for cold work. The HOVF is an attractive method to apply covering and recuperate dia

4. INFLUÊNCIA DO CONTEÚDO DE XILANAS NA BRANQUEABILIDADE, PROPRIEDADES HIGROSCÓPICAS, FISICO-MECÂNICAS E ÓPTICA DE POLPAS BRANQUEADAS DE EUCALIPTO
Bleached eucalypt kraft pulps are widely used in print and writing (P&W) and tissue paper manufacture. Among the quality requirements of pulp for these papers, xylan content has been controversial. The objective of this study was to evaluate the influence of xylan content on bleachability, hygroscopic, physic-mechanical and optical properties of the pulp. In

5. Investigations on cementitious composites based on rubber particle waste additions
The amount of waste rubber has gradually increased over recent years because of over-growing use of rubber products. The disposal of waste rubber has caused serious environmental problems. The incorporation of recycled materials into cementitious composites is a feasible alternative that has gained ground in civil construction. The performance of such materi

7. Optimization of the biodiesel synthesis of physic nut (jatropha curcas L.), via ethanol route, and determination of its uid-dynamic parameters / Otimização da síntese etanólica do biodiesel de pinhão manso (Jatropha curcas L.) e determinação de seus parâmetros fluidodinâmicos
The most applied process for biodiesel production is the transesterification reaction based on alkaline catalysts, due to their faster kinetics and appreciable conversion rate. Then, low cost catalysts (alkaline, alkaline earth and transition metal hydroxides), are often used. In such context, the present work aims to evaluate the catalytic activity of alkal

8. Influência da adição de rejeitos cerâmicos nas propriedades de cerâmica vermelha da região do Recôncavo Baiano / Influence of the addition of brick scraps in the proprieties of red ceramic in the region of the Recôncavo Baiano
The study of the physical and mechanic properties is an analysis of unquestioned importance on the production of the ceramic materials. In the region of the Recôncavo Baiano, there are ceramic and small brick factories, that still use rudimentary techniques, where the necessity of characterization of raw materials is denounced by the quality of the final pr

9. Avaliação do comportamento fisico-quimico-mecanico de misturas cimento-cinza-casca de arroz por meio de corpos-de-prova cilindricos e placas prensadas
The recycling is an effective tool to minimize environmental impact that is caused by human civilization. The utilization agricultural residual for rural construction is an efficient way for retain or reduce carbon emission to the atmosphere. However, the present-day techno logy is not enough to be a satisfactory level. A part of the residue is not consumed,
