Caracterização dos resíduos do processamento de mandioca para produção de bioetanol

Aiming to get the best economic advantage in ethanol production from cassava roots, this study presented a physiochemical characterization from two different types of solid waste in two types of processing of the raw materials in manufacturing ethanol. The processing of cassava roots begins with the disintegration and washing the roots with the addition of 20% more water to obtain a pulp which was treated and stirred in the reactor while adding enzyme α-amylase at a temperature of 90°C for 2 hours. Then we performed a pH adjustment while lowering the temperature to 60 ° C with the addition of the enzyme amiloglucosidase and then stirring for 14 hours. The hydrolyzate obtained was the source of two types of waste which are: i) Solid residue obtained after filtration of the hydrolyatze and ii) Solid waste obtained from filtering wine after alcoholic fermentation of the hydrolyzate with the addition of a dried yeast strain Y-940 manufactured by MAURI OF BRAZIL SA (2%) at a temperature of 25º C. The results of the laboratory analysis showed that the byproducts derived from the hydrolysis and fermentation showed very similar chemical compositions. With levels between 39 and 41% fiber, 0.5% lipids, 20 and 30% carbohydrates, protein 0.5 and 1.50, 6 and 8% acidity, and 20 and 30% soluble solids.

Análise e aferição de uma fresadora CNC através da utilização das tecnologias assistidas por computador, no escaneamento 3D de amostras e processamento de imagens

The use of computer-assisted technologies such as CAD - Computed Aided Design, CAM - Computed Aided Manufacturing, CAE - Computed Aided Engineering and CNC - Computed Numerical Control, are priorities in engineering and product designers. However, the dimensional measurement between the virtual and the real product design requires research, and dissemination procedures among its users. This work aims to use these technologies, through analysis and measurement of a CNC milling machine, designed and assembled in the university. Through the use of 3D scanning, and analyzing images of the machined samples, and its original virtual files, it was possible to compare the sizes of these samples in counterposition to the original virtual dimensions, we can state that the distortions between the real and virtual, are within acceptable limits for this type of equipment. As a secondary objective, this work seeks to disseminate and make more accessible the use of these technologies.

A resolução de problemas no contexto do estágio curricular supervisionado: dificuldades e limites de licenciandos em matemática

The aim was to investigate the difficulties and limits of four future mathematics teachers to conduct classes in regencies approach of problem solving. Based on participation in a course this approach, undergraduates elaborated three didactic sequences, which were taught by the activity of conducting classroom discipline Supervised Curricular Training. After this work, participated in an individual interview to report what had developed in classroom. The results showed difficulties in the following aspects: in the elaboration of didactic sequences; in providing an environment for discussion of resolution strategies students. Furthermore, the data analysis showed limits related: the lack of space at the school teacher to allow implementation of lessons developed; lack of basic mathematical knowledge of the students.

Aproveitamento do resíduo do processamento do café na composição de painéis MDP

A produção de produtos derivados de madeira e bambu vem crescendo nos últimos anos na busca de um aproveitamento mais racional dessas matériasprimas. Este trabalho tem por finalidade, o estudo da aplicação de resíduos do processamento do café em um painel MDP. Os painéis MDP foram produzidos com partículas de bambu da espécie Dendrocalamus giganteus e adição de partículas de casca de café na camada intermediária do painel, unidas por resina poliuretana à base de mamona. A caracterização físico-mecânica foi realizada baseando-se nas especificações da NBR 14810-3 (2006). Os resultados obtidos foram comparados com a norma brasileira NBR 14810-2 (2006), resultando em valores próximos aos comercialmente encontrados.

As dificuldades para a gestão do PIBID a partir do olhar de coordenadores e colaboradores em subprojetos na Faculdade de Ciências Bauru: limites e possibilidades

The Institutional Program of Initiation to Teaching, the PIBID, has by its nature the training of teachers. Focused on graduate students, the PIBID acts as a proposal for training beyond the mandatory classes, giving to the students that are entering the program, a great opportunity to improve their training as a teacher. Thus, this work focuses on a discussion of the PIBID at the Faculty of Sciences UNESP Bauru, aimed at subprojects of graduate students linked to the areas of Natural Sciences, Mathematics, Physics, Biology and Chemistry, working in an interdisciplinary way. I interviewed five teachers (three area coordinators and two contributors) seeking to verify, in their view, the understanding about the program and what were the major difficulties in the training of teachers. For contributors teachers and coordinators of the subprojects, interdisciplinarity has a very important role in the training of new teachers, and the PIBID allows to work this concept more broadly than just in the mandatory classes. However, a program so big like the PIBID comes with problems and it is in this context that this study was conducted. Coordinator teachers and contributors of the subprojects identified flaws in the program that may affect the activities proposed in the institutional design

Processamento e restituição digital de fotografias aéreas coloridas para estudo da cobertura vegetal

This work aimed to apply geoprocessing techniques to identify and to quantify the types of vegetal coverings in part of the county Botucatu – SP, having been divided into three phases: acquisition of data; georeferencing based on the digital topographic maps in 1:50000 scale and finally the thematic maps were generated. The methodology used to the analogical aerial photographics georeferencing showed efficient, considering that it was based on scientific procedures of residues

Processamento da amostra das silagens de grãos úmidos de sorgo com baixo e alto tanino na determinação da digestibilidade aparente em equinos

There were used four castrated male horses, crossbred. It was used randomized block by design for four replications. The objective was to evaluate the effect of using samples, ground or in natura, in the precision of the mobile nylon bag technique (MNBT) in comparison to the total collection (CT) method in oder to estimate the apparent digestibility coefficient (DC) of nutrients of high-moisture grains silage of sorghum with low (SSLT) and high (SSHT) tannin in the feeding equine. No effect was observed for MNBT and CT methods with in natura sample for DC of DM, OM, CE, CP to SSLT (P>0.05), whose average values were 81.71, 84.23, 82.27 e 81.43%, respectively. The MNBT did not showacuracy to evaluate of DC of the SSHT, with ground and in natura samples. It was concluded that MNBT containing in natura sample should be used to determinating the DC of SSLT to DM, OM, CE and CP for equines.

Calibração e validação de um método de medida da radiação solar global por meio de actinógrafos baseada em técnicas de processamento de imagens digitais

O objetivo do trabalho é desenvolver um sistema informático de digitalização e processamento de actinogramas baseado em técnicas de Processamento de Imagens Digitais e comparar com o sistema tradicional de medidas. Os actinogramas foram fornecidos pela Estação Meteorológica de Botucatu (FCA/UNESP). As análises preliminares indicam um desempenho satisfatório do software proposto, gerando medidas na mesma ordem de grandeza do método de referência para partição diária. O software proposto pertence a um projeto que se encontra ainda em andamento, onde rotinas de técnicas diversas continuam sendo implementadas no reconhecimento da curva de interesse para melhorar a qualidade do processamento das informações gráficas dos actinogramas. Os actinogramas estão em fase de digitalização para que o software possa ser testado com uma base de dados mais consistente, onde poderão ser identificados tendências temporais dos dados resultantes da aplicação das técnicas de Processamento de Imagens Digitais no monitoramento da radiação solar por actinógrafos.
