1. Noncultured epidermal cell suspension for the treatment of recalcitrant segmental vitiligo in a solid-organ transplant recipient,
Abstract Background: Anogenital warts are the leading sexually transmitted infection in patients seeking care at specialized clinics. They may display a vast array of forms, according to the interaction of the virus with the host's immunity. Cellular immunity is the epithelium's main form of defense against the virus, involving an active participation of th

3. REMOVAL OF NITRATE FROM DRINKING WATER BY USING PdCu STRUCTURED CATALYSTS BASED ON CORDIERITE MONOLITHS
Abstract Structured catalysts were prepared, characterized and evaluated in NO3 - removal from drinking water. Different suspensions containing a previously optimized PdCu/5wt% ZrO2-Al2O3 powder catalyst (hereinafter PdCu/5ZAp) were prepared and deposited on cordierite monoliths by washcoating. The effect of suspension concentration, the particle size, the i

4. Simulation of Active Eye Motion Using Finite Element Modelling
Abstract Dynamic simulation of human eye movements can significantly improve our understanding about the visuomotor system and also may be used for clinical applications. In this study we have developed a 3D finite element model of the eye orbit. The major novel issues which are considered in this work are using dynamic finite element method for properly ma

5. Streptomyces lunalinharesii 235 prevents the formation of a sulfate-reducing bacterial biofilm
ABSTRACT Streptomyces lunalinharesii strain 235 produces an antimicrobial substance that is active against sulfate reducing bacteria, the major bacterial group responsible for biofilm formation and biocorrosion in petroleum reservoirs. The use of this antimicrobial substance for sulfate reducing bacteria control is therefore a promising alternative to chemic

6. Evaluation of limonoid production in suspension cell culture of Citrus sinensis
ABSTRACTThe use of cell and plant tissue culture techniques to produce economically important active metabolites has been growing. Among these substances are total limonoid aglycones, which are produced by "pera" orange (Citrus sinensis (L.) Osbeck, Rutaceae) and have received considerable attention because of their anticancer actions. The main objective of

7. Mortality of Oryzophagus oryzae (Costa Lima, 1936) (Coleoptera: Curculionidae) and Spodoptera frugiperda (J E Smith, 1797) (Lepidoptera: Noctuidae) Larvae Exposed to Bacillus thuringiensis and Extracts of Melia azedarach
Oryzophagus oryzae (Costa Lima 1936) (Coleoptera: Curculionidae) and Spodoptera frugiperda (J E Smith, 1797) (Lepidoptera: Noctuidae) cause important crop losses in southern Brazil. Control is possible by the use of the bacteria Bacillus thuringiensis and extracts of Melia azedarach. This study aimed to evaluate the mortality, in vivo, of O. oryzae and S. fr

8. Estudo do ruído de rodagem estrutural através da análise dos caminhos de transferência de energia - TPA / Structure-borne road noise study using transfer path analysis, TPA
The road noise, vibration and harshness (Road NVH) present from 20 Hz to 1000 Hz approximately, begins from the tires vibration and acoustic propagation and their interactions with the road surfaces. In these noise sources, both structural-borne and air-borne noise contributions are relevant to vehicle refinement. The constant efforts to study the vehicle as

9. Synthesis of a Magneto-Rheological vehicle suspension system built on the variable structure control approach
The synthesis of a magneto-rheological vehicle suspension system built on the variable structure control approach is considered in the present work. The suspension is synthesized in order to improve the ride comfort obtained by a standard passive suspension. Although a nominal half-vehicle model with rigid body is considered in the synthesis of the suspensio

11. Controle H-infinito em suspensões ativas aplicando técnicas baseadas em desigualdades matriciais lineares / H-infinity control at active suspension applying techniques based onlinear matrix inequalities
Nesse estudo foram aplicadas as técnicas de controle H1 em modelos de suspensões ativas veiculares. O interesse de controlar o sistema baseado nessa técnica está também no fato de que sua obtenção pode ser feita através da solução de problemas de otimização, sendo estes baseados no uso de Desigualdades Matriciais Lineares (LMI, do inglês Linear
