2. Neuro-fuzzy Hybrid System for Monitoring Wood Moisture Content During Drying
ABSTRACT The heterogeneous behavior of wood during drying is a process difficult to control. The objective of this study was to evaluate the accuracy of the neuro-fuzzy hybrid system for monitoring wood moisture during drying. Eucalyptus urophylla x Eucalyptus grandis samples (2 x 2 x 4 cm) were saturated and dried in climatic chamber for 15 days. Basic den

4. Wave passage effects on the seismic response of a maglev vehicle moving on multi-span guideway
As a seismic wave travels along the separate supports of an extended structure, the structure is subjected to multiple-support excitation due to seismic wave propagation. Considering the seismic wave passage effect, this paper describes seismic analysis of a maglev vehicle moving on a multiply supported gudieway. The guideway system is modeled as a series of

5. ESTUDO DE UM REATOR SOLAR HÍBRIDO PARA CURA ACELERADA DO CONCRETO EM ÁGUA MORNA. / STUDY OF A HYBRID SOLAR REACTOR FOR ACCELERATED CURING OF CONCRETE IN WARM WATER.
The Portland cement concrete material is the most consumed after the water worldwide due to their versatility molding, strength and durability as a structural material. The curing is the procedure that aims to keep the concrete saturated with water in their early ages and it is essential to ensure the reactions of cement hydration, promoting its consolidatio

8. Produção e caracterização do anticorpo monoclonal aDEC205 acoplado a proteína MSP-1 (19) de Plasmodium chabaudi. / Production and characterization of a monoclonal antibody aDEC205 coupled to MSP-1(19) protein from Plasmodium chabaudi.
Despite the strong activation of the immune system that occurs during infection by Plasmodium, the immunological memory to infection is restricted to patients residing in endemic areas. Thus it is important to the generation of methods to induce an effective immune response against the parasite. In this context, the targeting of antigens to the central cells

9. Influence of chlorhexidine application on longitudinal adhesive bond strength in deciduous teeth
The aim of this study was to evaluate the influence of applying 2% chlorhexidine for 30 seconds after phosphoric acid conditioning of dentin on the immediate and long-term bond strengths in deciduous teeth. The occlusal enamel was removed from 40 human sound deciduous molars, which were exfoliated by natural means, and the dentin was conditioned with 37% pho

11. Avaliação do substrato dentinário irradiado com laser de Er:YAG : resistência de união, padrão de fratura e análise ultramorfológica / Evaluation of dentin irradiated with Er:YAG laser : bond strength, failure pattern and ultramorphology analysis
The Er:YAG laser has been widely used in Dentistry and because its ability to remove mineralized dental tissues, it is indicate to be used in Operative Dentistry. As the Er:YAG laser is recent, little is known about the consequences of dental tissues irradiation and their effects on adhesive restorative procedures. Thus, the objectives of this study were to
