1. Dimensionalidade fractal e invariância de escala em circuitos elétricos AC e linhas de transmissão
Resumo A geometria fractal fascina pela capacidade de descrever formas geométricas complexas e que usualmente estão presentes no mundo real . A dimensão fractal ou de Hausdorff d é utilizada para descrever leis de invariância de escala, em que as funções autossimilares seguem uma lei da forma f ( s x ) = s d f ( x ), sendo s o fator de escala. Intim

2. Scaling Symmetries and Conservation Laws for Variable-coefficients Nonlinear Dispersive Equations
RESUMO. Simetrias de escala surgem em diferentes ramos da física e abordagens baseadas em simetria são poderosas ferramentas para estudar modelos invariantes por escala, pois podem fornecer leis de conservação que não são óbvias por inspeção. Nessa perspectiva, a classe de equações dispersivas não-lineares com coeficientes variáveis vc K ( m ,

3. Effects of Macrosegregation and Microstructure on the Corrosion Resistance and Hardness of a Directionally Solidified Zn-5.0wt.%Mg Alloy
This study aims to analyze the influence of macrosegregation on microstructure evolution, and of microstructure length scale on the corrosion resistance of a Zn-5.0wt.%Mg alloy casting. The analyzed samples were taken along the length of castings unidirectionally solidified in unsteady state conditions of heat extraction. Microstructure characterization, mic

4. Tri-modal Microstructure in Different Loading Zones Under TA15 Ti-alloy Isothermal Local Conventional Forging and Given Subsequent Heat Treatment
For TA15 Ti-alloy large-scale component, isothermal local conventional forging (ILCF) combined with subsequent heat treatment provides a feasible approach to obtain a tri-modal microstructure with attractive comprehensive performance. However the tri-modal microstructure characteristics and evolution laws in the first and second loading zones are lack of und

5. AVALIAÇÃO DOS RESÍDUOS GERADOS DURANTE A DESTRUIÇÃO DE PCBS PELO PROCESSO CATALISADO POR BASE
There are many processes capable of decontamination of polychlorinated biphenyls in several matrixes. The set of inputs, materials, operation conditions and efficiencies are wide. The base catalyzed dechlorination process shows application potential in great scale, mainly due mild chemical reaction conditions and low cost raw materials. The KPEG is a familia

6. OPERATOR EFFORT ON THE OPERATION OF THE KNAPSACK SPRAYER PUMPING LEVER
ABSTRACT Several equipments are used in the application of agrochemicals by small scale farmers, with emphasis on the knapsack hand sprayer due to the low cost of acquisition and viability of use in different operating conditions. Although it is an equipment widely used, few studies have been developed in order to ascertain its functional characteristics. Th

7. INFLUENCE OF THE MODEL SCALE ON HYDRODYNAMIC SCALING IN CFB BOILERS
Abstract The paper presents the results of experimental verification of the simplified set of scaling parameters for which the particle density as well as the cold model length scale may be chosen independently. The tests were carried out on two large scale 1/10 and 1/20 geometrically similar cold models of the Lagisza 966 MWth supercritical CFB boiler. The

8. Food production in solidarity economy: an issue that goes beyond laws
Abstract Food production within the context of solidarity economy is an alternative way to offer employment and income for a significant part of the Brazilian population. The purpose of this study was to carry out a business diagnosis in order to evaluate the facilities, the production process and hygiene practices of seven solidarity economy enterprises loc

9. On dynamic self-organization: examples from magmatic and other geochemical systems
Standard Liesegang banding is the display of parallel bands of precipitate formed periodically when co-precipitate ions interdiffuse in a gel medium. The most striking resemblance with Liesegang patterns in Nature lies in the diverse scenery of banded textural features commonly observed in some geological materials, such as geodes, agates, malachites, as wel

10. Influência de um fragmento florestal sobre as comunidades de macroinvertebrados de um córrego tropical degradado
Land use changes have resulted in large environmental impacts, and in agricultural landscapes sometimes only forest fragments remain. However, riparian forest remnants can influence positively stream water quality, and serve as refuge to aquatic species sensible to deforestation. We evaluated if the presence of a riparian forest remnant influences the struct

11. DESENVOLVIMENTO DE REQUEIJÃO CREMOSO COM BAIXO TEOR DE LACTOSE PRODUZIDO POR ACIDIFICAÇÃO DIRETA E COAGULAÇÃO ENZIMÁTICA / DEVELOPMENT OF REQUEIJÃO CREMOSO WITH REDUCED LACTOSE CONTENT PRODUCED BY DIRECT ACIDIFICATION AND ENZYMATIC COAGULATION
Much of the world population has problems in consuming milk and dairy products because some people are lactose intolerant. To be absorbed in the intestine lactose needs to be hydrolyzed by lactase enzyme. People with lactose intolerance do not produce lactase and therefore can not enjoy milk and dairy products benefits. This work aim to prepare requeijões c

12. Media piracy in emerging economies
Media Piracy in Emerging Economies is the first independent, large-scale study of music, film and software piracy in the developing world, with a focus on Brazil, India, Russia, South Africa, Mexico and Bolivia. Based on three years of work by some thirty-five researchers, the study tells two overarching stories: one tracing the explosive growth of piracy as
