This is a theoretical paper that seeks to work, through interrelations, concepts relating to contemporary aesthetics in parallel to phenomenon of perception. It begins with the aesthetic interaction between content and form in order to trace the development of perceptionexpression interaction, inserted into the mutual action of its physical and psychical aspects "through behind" a thinking mind. In order to generalize such interaction to reality itself as a natural and evolutionary cycle, we start from the analysis of perception of more complex organic beings, endowed with consciousness, to extend the question to the simplest organic beings, as even to inorganics. It is based upon principles of equilibrium and unity in diversity to highlight a historical fact that it seems undeniable: that man evolves and this evolution, their perception clears, while that is particularized your experience and aesthetic judgment. Having in the art, the activity can boost an evolution more profound while pleasurable.

A Cie. <<à fleur de peau>>, fundada em 1988 pela brasileira Denise Namura e pelo alemão Michael Bugdahn, sediada na França, desenvolve uma linguagem estéticoexpressiva própria, caracterizada por integrar áreas artísticas distintas, como a dança, as artes circenses, o teatro e a mímica. Tal confluência decorre da formação de ambos os fundadores, atuais diretores e coreógrafos da companhia de dança-teatro. O intercâmbio dessa companhia com o Brasil é constante, incluindo apresentações de seus espetácul os, coreografias para outras companhias e oficinas. Em uma de suas vindas à cidade de São Paulo, no ano de 2013, tivemos a oportunidade de entrar em contato com a pesquisa de linguagem da Cie. Em 2014, os fundadores foram convidados a coreografar um espetáculo infantil para a Cia. de Danças de Diadema, localizada no ABCDMR paulista. Este estudo partiu do interesse em conhecer o trabalho desenvolvido por Namura e Bugdahn. A partir desse encontro, pudemos observar, relatar e refletir sobre como ocorreu a tran smissão dessa linguagem estético-expressiva no processo de criação do espetáculo A Mão do Meio - Sinfonia Lúdica aos bailarinos da companhia diademense. Para tanto, acompanhamos os ensaios referentes ao espetáculo durante os períodos anterior e posterior à pré-estreia e à estreia oficial do espetáculo. Posteriormente, foi possível tecer outra reflexão, dessa vez sobre os elementos teatrais componentes dessa linguagem, que a tornam diferente em relação ao processo de criação artística e apresentação da obra

The biomass resulting from processing sugarcane bagasse has been considered a source of cellulose with the potential production of bio-fuels. This lignocellulose can be processed into ethanol since is hydrolyzed by chemical processes (acids) or biotechnology (enzymes) which generate sugars suit for fermentation. This study had the objective to utilize physical and chemical pre-treatment processes for prehydrolysis of sugarcane bagasse. The experimental treatment was adjusted at a factor of 4 X 2, by the combination of pre-hydrolysis timing (15, 30, 45 and 60 minutes) and sulfuric acid concentrations (7.0% and 9.0%) which was incubated at a temperature of 121° C in an autoclave. The treatment data was subjected to analysis of the variance and averages which were compared using the Tukey test with a probability of 5%. The results obtained showed that through pretreatment acid applied on the lignocellulose material, there was a significant break from the substrate fibers like cellulose, hemicellulose and lignin.

The production of ethanol and sugar from sugarcane juice generate as byproduct, the bagasse. Currently, the bagasse, an industrial lignocellulosic biomass, can be used for production of second-generation ethanol, since when it is submitted to hydrolytic processes generates fermentable sugars. The objective of this study was to produce fungal enzymes capable of hydrolyzing this lignocellulosic biomass to generate glucose. For this, we used the mushroom species Lentinula edodes, Pleurotus ostreatus, Pleurotus eryngii, and Pycnoporus sanguineus as potential sources of laccase, manganese peroxidase and lignin peroxidase enzymes, capable of hydrolyzing the crushed sugarcane. The hydrolysis process was performed with the highest enzymatic activities observed from laccase in L. edodes (39.23 U-mL after 25 day incubation), P. ostreatus (2.5 U U-mL after 27 day incubation), P. sanguineus (80 U-mL after 27 days of incubation) and P. eryngii (16.45 U-mL 15 days incubation). MnP and LiP showed no significant results. The enzymatic hydrolysis of sugarcane bagasse in natura (32,17% hemicellulose, cellulose 52,45% and 10,62% lignin) and bagasse hydrolyzate with 7,0% H2SO4 (0,20% hemicellulose, 68,82% to 25,33% cellulose and lignin) were evaluated for each enzymatic obtained. Compared to others, the enzymes produced by P. sanguineus incubated in sugarcane bagasse showed better efficiency resulting in glucose with an average content of 0,14 g-L. Although the levels of glucose determined in this work were low in relation to the literature, it can be stated that the laccase, manganese peroxidase and lignin peroxidase enzymes demonstrated good hydrolytic potential, especially those produced by the fungus P. sanguineus.

This work evaluates the existing potential in the state of Sao Paulo for the generation of electrical energy using the sugar cane bagasse as fuel. As the bagasse is a by-product of the sugarcane and alcohol industry and it is produced in large scale in the country, mainly in the state of Sao Paulo, it is important to develop researches that aim the best utilization of this input. In order to determine its potential, at first, a study was conducted considering the utilization of the cogeneration, which is a common practice in the plants of the sector. However, it was concluded that the cogeneration could provide a higher quantity of energy if more modern technologies and more efficient processes were used. Another study to estimate the potential considered a system of gasification of the sugar cane bagasse integrated with the combined cycle (BIG/GTCC). It was concluded that this technology can provide a considerable increase in the electrical supply. In this work it was also developed an energetic study based on real data from a plant located in the state of Sao Paulo. A thermodynamic analysis was done in the existing equipment of the cogeneration section of the plant. And another analysis was done considering the implementation of the BIG/GTCC technology to the cogeneration system. Comparing the results of both settings, it was concluded that the utilization of the sugar cane bagasse integrated to a combined cycle increased considerably the efficiency in the generation of electricity of the plant, increasing more than six times its production capacity of electrical energy

A caracterização anatômica, física, mecânica e química da madeira fornece informações importantes para sua melhor utilização. Contudo, para que madeiras se tornem boa opção para o mercado de pisos, adicionalmente é necessária a realização de ensaios que simulem suas reais condições em serviço. Esses ensaios simulam o pisoteio executado pelos sapatos de salto com pequenas áreas de pressão, o arraste e a queda de objetos, a resistência à abrasão da superfície e o atrito oferecido durante o deslocamento de pessoas que caminham sobre ele. Grande dificuldade da seleção de novas madeiras para pisos está na ausência de valores de referência físico-mecânicos. O presente trabalho visou a caracterizar as madeiras de Eucalyptus clöeziana F. Muell, de Eucalyptus microcorys F. Muell e de Corymbia maculata Hook, para as propriedades de densidade básica, retratibilidade, aplicação de carga rolante, de atrito estático e dinâmico, endentação causada por cargas aplicadas em pequenas áreas, impacto da esfera de aço cadente e resistência à abrasão. Foi observado que as madeiras estudadas podem ser utilizadas para a confecção de pisos, de acordo com seus resultados obtidos e por meio de comparações com resultados de literatura.
