Adsorção do corante luganil azul por espuma de poliuretano

The industrial development has created many environmental problems that can be observed through the changes in air, soil and water. The pollution of water bodies with compounds present in textile effluents cause beyond the visual pollution, changes in biological cycles, mainly by changing the process of photosynthesis. Due to these environmental implications it is necessary a treatment of livestock manure. The process of adsorption of the dye is a technique that has been successfully employed for effective removal of the color of the effluent. The purpose of this study was to investigate the application of a polyurethane foam plant of castor oil as an alternative adsorbent for removal of dyes in textile effluents. The study was conducted with the dye “luganil azul”, as adsorbent and the foam in a flexible manner and sprayed. It also investigated the influence of pH on the adsorption dye. The kinetic data were obtained, noting that the pH influence on adsorption. Adsorption isotherms of the dye in aqueous solution using the foam in a flexible manner also were determined experimentally.

Análise preliminar para a estimativa da perda de calor sensível de um fluido homogêneo térmico em um reservatório de geometria cilindrica

This work analyzed the loss of sensible heat from one fluid to be considered homogeneous heat distribution on a thermal reservoir with cylindrical geometries composite insulating layers. We studied two thermal reservoirs with a volume of 20 liters, and the first has a layer thickness of 75 mm of expanding polyurethane foam wrapped in the polycarbonate container and the second container has only layer thickness of 5 mm of polycarbonate, as insulation of fluid of the external environment. The experimental results are compared with theoretical results obtained through a calculation script, displayed and detailed during the work development, from the theory of energy balance. The maximum error introduced between the theoretical and experimental results were 3.5% and 1.4% respectively for the Boilers with or without a polyurethane coating

Produção de cerveja, utilizando méis de diferentes origens botânicas como adjuntos

This study aimed to produce beer, using different botanical origins of honeys (orange, eucalyptus and wild), as malt adjuncts, and their Physical-chemical and sensorial characterizations. The production was made with malt, water, hops and honey. All musts were adjusted to 12 Brix, and the concentration of honey in the formulation was 45% (based on the extract), except for the control (0%). The physical and chemical analysis were performed on malt (extract content), honey (pH, free acidity, lactonic acidity, total acidity, color, turbidity, extract content, moisture content, reducing sugar, total reducing sugar and sucrose) in wort (content extract, pH, color, turbidity, fermentability ,bitterness and total acidity) and beer apparent extract, apparent fermentability, real extract, real fermentability, alcohol content, pH, total acidity, total foam, foam density , bitterness, carbon dioxide, color and turbidity). Sensory analysis was performed by nine-points hedonic scale testing. The attributes evaluated were appearance, aroma, flavor and overall. The results were submitted to ANOVA and means compared by Tukey testing at a 5% of probability. Beer with honey as adjuncts’ had high fermentability and low content of fat, compared to the pure malt beer. The addition of honey as an adjunct did not affect the majority of the physical-chemical parameters, except for turbidity, whereas beer with honey showed the highest value for this feature, in addition, it has also presented their biterness differences the values for beer with honey were lower. The different types of honeys did not affect the acceptability of beer, however, the beer with honey showed greater acceptance between beer with malt and honey

Softwares livres e prototipagem rápida aplicados na engenharia

In modern industry we see a growing need for answers cheaper, accurate and quick to deliver solutions and products to be able to remain competitive. In this way the inclusion of open source software and Rapid Prototyping tools have proven very important to obtain the expected results. This work, through information gathering, analysis software and their applicability, search tools commercially available rapid prototyping will demonstrate the importance of these tools and will also present possible configurations for a space for rapid prototyping within the university, as a proposal to implement a rapid prototyping laboratory at the Faculdade de Engenharia de Guaratinguetá

Televisão digital interativa na educação: desenvolvimento de um conteúdo. complementar ao ensino

This work had as objective the development of a prototype of educational content, as an experimental process, making use of resources from Interactive Digital TV. The characteristics of interactive digital terrestrial television are presented, in the form of a media mode capable of performing as a complementary source to education. The methodology used is composed of four phases: deduction, analysis, induction and synthesis. Its conception takes as issue the expressed need stated by UNESCO to use ICT (Information and Communications Technology) towards education, as well as the possibility of applying digital television in an educational process. The content is structured in the form of a quiz, a type of question-answer game as an informal way of education for high school students. The prototype developed in this work is presented as a structural script and map, taking into account the necessary activities and routines to put it into operation in the tested environments, eclipse, virtual set-top-box and Developer Box. The practice of prototyping was carried out in NCLua, based on middleware Ginga. As a result, we concluded that Ginga offers enough support to carry out the task, providing characteristics of interaction to publish the proposed content, at the moment of the actual practice.
