Há uma grande expectativa para o desenvolvimento de biossensores miniaturizados, que permitam análises mais eficientes e rápidas, em matrizes complexas como as encontradas: no ar, alimentos, águas residuais e em medicamentos. Recentemente, filmes poliméricos inteligentes ativados por estímulo externo têm atraído bastante interesse no desenvolvimento desses tais nanosensores para uso em sistemas químicos e bioquímicos. Estes materiais apresentam uma alta sensibilidade a alterações físicas ou químicas ocorridas na sua interface, e respondem seletivamente a essas mudanças para se adaptarem ao meio. Juntando-se as propriedades estímulo-responsivas desses polímeros com a alta seletividade de reações biológicas tem-se uma excelente combinação para a criação de nano biossensores. A esse tipo de sistema: interfaces/material biológico adota-se a nomenclatura biointerface. As biointerfaces são biossensores em potencial, e na preparação dos biossensores a tarefa mais complicada na sua preparação é o desenvolvimento de superfícies adequadas para o interfaceamento com material biológico, de maneira que a parte biológica possa atuar de forma sensível e estável. A primeira etapa consistiu na produção e caracterização dos polímeros escova (P2VP), os quais serão preparados pelo processo de deposição térmica. A caracterização dos mesmos foi realizada por imagens microscopia de força atômica (AFM), via eletroquímica e por transmissão de ressonância plasmônica de superfície. Na etapa posterior foi estudada a imobilização da glicose oxidase para a preparação do biossensor. O dispositivo fabricado foi empregado para a determinação direta de glicose. Desta forma, esperou-se obter uma metodologia de menor custo e tempo de análise. Logo, este estudo irá contribuir de forma significativa sobre os processos de montagem de biossensores a partir de compostos nanoestruturados. Foram utilizadas técnicas de ...

This work presents a fast, easy, standardized and planned method to build family homes in order to collaborate with the decline of housing deficit and, at the same time, meet families who wish to invest in building their own houses, once that our country is experiencing an economical prosperity . This method has been widely used nowadays because it is being deployed in large-scale and in a standardized pattern, reducing decreasing significantly the construction time. The concrete wall, shaped in loco depends on unique processes. For this reason, a well trained staff is required so the constructive process can be executed in a fast pace, showing better results than other construction methods. This project will address all the materials used to build the molded concrete walls in loco, their sequence assembly, application, types, characteristics and performances. At the end, a way used by building companies of locating the concrete will also be given. Although there is no specific Brazilian norm for this type of construction, a study on this topic will soon be released. Therefore, the studies for the execution of this project were based on Brazilian standards prevailing at the time, construction magazines and books that are based on building methods considered more common

O presente trabalho apresenta estudos de casos de expressões audiovisuais reunidas por Jan Simons sob a denominação de narrativas complexas, propondo a sua utilização como referência para aplicação de interação na TV Digital. O corpus é constituído das seguintes produções submetidas a essa classificação: forking path narratives e puzzle films com The Butterfly Effect (Erci Bress e J. Mackye Gruber, 2004); mind-game films com Lola Rennt (Tom Tykwer, 1998); modular narratives com Nine Lives (GPS films, 2005), database narratives e modular narratives com Pulp Fiction (Quentin Tarantino, 1994); network narratives com Babel (Alejandro Gonzalez, 2006) e subjectives stories com Being John Malkovich (Spike Jonze, 1999). Compreendida como uma técnica de seleção e articulação de fragmentos de sentidos na composição do discurso audiovisual, aponta-se a montagem como um mecanismo propulsor de interação, manifestada pela transferência da sincronização dos módulos de sentidos que compõe a mensagem ou na construção de discursos audiovisuais com linearidade que se difere do nível dos acontecimentos. A pesquisa gerou um capítulo de livro, duas publicações em revistas científicas, além de integrar anais de diversos eventos acadêmicos

A large proportion of fresh water is greatly impaired due to increasing pollution; this could be minimized through the expansion of investment in sanitation programs. But the major problem faced by third world countries and developing ones in this respect, is the high cost of projects and their implementation. In an attempt to find a simple technology, efficient and inexpensive, this study aimed to verify the effectiveness of using constructed wetland systems (CWS) for removal of bacteria and nutrients from sanitary sewer effluent from the STS Piracicamirim - Piracicaba - SP. The installation of prototypes was followed, and testing prior to regularize the flow held, but due to malfunction of these and outages of the STS activity can not evaluate the effectiveness of both as to the parameters proposed: temperature, pH, dissolved oxygen, conductivity, total dissolved solids (TDS), nitrite, nitrate, ammonia, total nitrogen, total phosphorus, chemical oxygen demand (COD), sulfide, sulfate, biochemical oxygen demand (BOD), total coliform and Escherichia coli. To establish results about the effectiveness of these types if the system were conducted literature reviews of papers published with the same theme. Analysis of these results showed fairly good efficiencies in wastewater treatment, especially for nutrients and coliforms

This work aims to analyze data from a Natural Electric Potential landfill type ditch located in Cordeirópolis (SP). The procedure measures initially involved the assembly and installation of an apparatus cables, sensors and drain geophysical measurements and flow rate of biogas in a ditch later filled by solid waste. Biogas is a product of degradation of organic matter in waste by the action of microorganisms in an anaerobic environment. Its features high methane content in the gas potentially usable as fuel in energy generation systems or steam. The study area is characterized by clayey soil composition change from the diabase sill correlated to the event Serra Geral Formation siltstones overlapping Tatuí with groundwater level site around 50m. The cables were installed vertically in parallel with drain gas manifold, which allowed the collection of data by the technique geophysical logging every 15 days over a period of eight months. For data analysis we used four parameters in the study, the closing time of the ditch, natural electric potential, the flow velocity of biogas and rain. With the tabulated data plots were constructed for each collection day showing values in the range of the cable is in contact with waste (200 cm - 400 cm) and range of the cable in contact with the soil (600 cm - 800 cm). Subsequently graphs were generated with the period of eight months to analyze the data tabulated. A statistical correlation data, which show the influence of rainfall on the production of biogas. The results were satisfactory and demonstrated the feasibility of the research method in studies for the feasibility analysis for the capture of biogas energy

In view of the need to develop a device for security and lateral protection, due to the Resolution 323/09 of CONTRAN, which requires the use of such equipment for most trucks and tow trucks, the objective of this work is to develop a project for an aluminum lateral protection device, according to the ABNT NBR 14.148 regulation, that, among many specifications, stipulates that the equipment must support a load of 5 kN and suffer a maximum deflection of 30mm, but does not say what material it should be made of. The reason for choosing aluminum is because of its low density, so as not to significantly increase the curb weight of the truck, which, consequently, reduces CO2 emissions and maintenance expenses. Additionally, this material presents a good resistance/weight ratio, high resistance to corrosion, excellent surface finish and it's fully recyclable; reason why it has been gaining the attention of many industry segments. For the realization of the project, profiles were chosen to make the assembly of the set, and then a finite elements analysis was performed in the HyperWorks software, to verify if the designed device would support the loads stipulated by the regulation. One details to note is that these simulation programs could show inaccuracies, because of the size and shape of the elements that compose the mesh, and for many other reasons, so it is necessary that, even with the results coming back satisfactory, actual physical tests are conducted to validate the proper functioning of the equipment, which was not done for this study
