1. THEORETICAL ANALYSIS AND EXPERIMENTAL STUDY ON THE PROCESS OF CONVEYING AGRICULTURAL FIBER MATERIALS BY SCREW CONVEYORS
ABSTRACT To improve the conveying efficiency and working stability of a screw conveyor, the feeding methods, running conditions and flow characteristics of materials were studied by theoretical analysis and experiments. The theoretical analysis results show that the screw conveyor runs more stably when the helix angle of the screw blade is equal to the movin

3. Viabilização técnica e econômica da lavra contínua de minério de ferro com o uso de sistema de britagem móvel in pit auto propelido
The conventional mining methods employed in most iron ore mines around the world are based in truck haulage. Starting in 1977, Samarco S/A has successfully introduced an innovative mining method in its iron ore mine located in Mariana, MG, Brazil. Samarcos mining method, known as belt conveyor-based mining, has replaced haul trucks for belt conveyors on the

4. Estudo da relação entre ataque oxidativo, sistema de defesa antioxidante e atividade mitocondrial em ratos submetidos a um protocolo de indução ao overtraining em esteira / Study of the relation ship between oxidative damage, antioxidant defense system and mitochondrial activity in rats induced to a treadmill overtraining protocol
O overtraining e um processo continuo de treinamento intenso que pode gerar um declínio curto no desempenho, denominado de overreaching funcional (FOR), o qual conduz eventualmente a uma melhoria no desempenho apos um breve período de recuperação (dias-semanas); ou um declínio mais prolongado no desempenho, caracterizado como overreaching nao funcional

5. Project and assembling of pneumatic transport pilot unit in diluted phase for studying the relationship between the pressure drop and the distribution of granular particles into the cross section of industrial pipes / Projeto e montagem de unidade piloto de transporte pneumatico em fase diluida para estudo da relação entre a perda de carga e a distribuição de particulas granulares na seção transversal de dutos industriais
The pneumatic transport that involves the use of air particles to move materials through pipes is a major operation in various industries and chemical processes. Typical examples are systems for the conversion of energy from coal, catalytic cracking, drying and transport of solid and fine granular. The conventional pneumatic transport is often operated in di

6. PROPÓSITOS EDUCACIONAIS NO MEIO ON-LINE: O CASO DOS CURSOS DE INGLÊS GRATUITOS / EDUCATIONAL PURPOSES ON THE WEB: THE CASE OF FREE ENGLISH COURSES
A quick search through the Internet allows us to find an expressive number of free English courses, representing not only the possibilities that this new means of communication offers, but also the importance that this language took, mainly due to the cultural and economical domination exerted by the countries related to it. Thus, through this work, I try bo
