13. Isolation of whiskers from natural sources and their dispersed in a non-aqueous medium
Abstract Whiskers have been used as a nanomaterial dispersed in polymer matrices to modify the microscopic and macroscopic properties of the polymer. These nanomaterials can be isolated from cellulose, one of the most abundant natural renewable sources of biodegradable polymer. In this study, whiskers were isolated from sugarcane bagasse and corn cob straw f

14. Residual Stress, Microstructure and Hardness of Thin-Walled Low-Carbon Steel Pipes Welded Manually
The aim of this work is to evaluate the welding residual stress profile in ASTM A106 Gr. B steel pipes with 4" diameter and to correlate this profile with the microstructure and hardness of the joint. The results showed that the residual stresses are more uniform for a lower welding heat input. Higher welding heat input causes not only a non-uniformity of th

15. Washing treatment impact on print quality of screen printed knitted fabrics
ABSTRACT The surface of textile materials is highly textured, commonly in non-uniform ways. Because of this texture effect, textile surface appears rougher and more porous than other printing substrates, which can cause excessive ink penetration during printing process. Next, washing process is very important factor because it influences ink characteristics

16. Muscle residual force enhancement: a brief review
Muscle residual force enhancement has been observed in different muscle preparations for more than half a century. Nonetheless, its mechanism remains unclear; to date, there are three generally accepted hypotheses: 1) sarcomere length non-uniformity, 2) engagement of passive elements, and 3) an increased number of cross-bridges. The first hypothesis uses sar

17. Energetic use of wood waste in one center for the production of red ceramics in São Paulo State / Uso energético de resíduos madeireiros em um pólo de produção de cerâmicas vermelhas do Estado de São Paulo
The use of forest biomass is an important alternative of renewable energy source, economic, technical and environmentally viable, fighting for space with other energy sources, more expensive or non-renewable, such as natural gas, electricity, diesel and LPG. Within the industrial sector, biggest consumer of biomass energy, the segment of red ceramics represe

18. Variabilidade espacial da uniformidade da lÃmina de Ãgua aplicada por sistemas fixos de irrigaÃÃo por aspersÃo / Spatial variability of water level uniformity applied by fixed sprinkler irrigation systems
Water application uniformity is an important factor to be considered in the evaluation of sprinkler irrigation systems. The uniformity depends on the type of sprinkler and its operational conditions, the display and space among the sprinklers on the field, and also the wind speed and direction during the water applying period. This work contributes to develo

19. The resigned qualification: the bad formation of workforce how a structural problem of Brazilian development / A qualificação resignada : A má formação da força de trabalho como um problema estrutural do desenvolvimento brasileiro
This work makes a diagnosis of training policy and professional education system in Brazil. The subject had never been so professional education on the agenda in the sociology of work and labor economics, but came to light at the end of the twentieth century, when the new stage of accumulation explained the decline of Fordism-Taylorism, also denouncing the n

20. A new approach for obtaining rapid uniformity in rice (Oryza sativa L.) via a 3x x 2x cross
A triploid (2n = 3x = 36) rice plant was obtained by screening a twin seedling population in which each seed germinated to two or three sprouts that were then crossed with diploid plants. One diploid plant was chosen among the various F1 progenies and developed into an F2 population via self-pollination. Compared with the control variety Shanyou 63, this F2

21. Seismic data inversion by cross-hole tomography using geometrically uniform spatial coverage
One of the inversion schemes most employed in seismic tomography processing is least squares and derived algorithms, using as input data the vector of first arrivals. A division of the whole space between sources and receivers is performed, constructing a pixel model with its elements of the same size. Spatial coverage is defined, then, as the sum of travele

22. Evaluation of boom hydraulic sprayers in the region of Uberlândia-MG / Avaliação de pulverizadores hidráulicos de barra na região de Uberlândia-MG
Any and every manner of pesticide application represents environmental risks, which must be minimized by the use of proper knowledge and technology, assuring a sustainable food production. Often, great importance is given to the pesticide and little to the application technique. The identification of the conservation state and mode of use of the sprayers in

23. Local perceptions of community managers on the certification of the Forest Stewardship Council (FSC) for non-timber forest products in the state of Acre / Percepções locais de manejadores comunitários sobre a certificação do Conselho de Manejo Florestal (FSC) para produtos florestais não madeireiros no Estado do Acre
The certification of the Forest Stewardship Council is a management tool that aims to encourage the sustainable management of forest products considering social, economic and environmental aspects. In recent years, there have been efforts promoting community certification as a tool for developing non-timber forest products (NTFPs), hence generating many bene

24. Eficiência da área de sombreamento artificial no bem-estar de novilhas leiteiras criadas a pasto / Artificial shadow area efficiency in milk heifers welfare in pastures
This study had as objective to evaluate and quantify the effect of artificial shading proportioned by different shadow areas under physiology and behavior of milk heifers, in pastures. Research was realized in the period from February to April, 2008. Experimental area was divided in 20 adjacent parcels with 84m2 to treatments 1, 2 and 3 and with 70m2 to trea
