The work aims to understand and analyze the different construction processes, and what are the guidelines for the development of multi-floor building projects carried out in timber structures. These processes bring about a new way of project thinking, which must consider factors restricted to situations involving wood as a structure material. Since this is a structural building system that is still little disseminated in the civil construction scenario at a world level, it is essential to have a technical capability for a complete understanding of the whole process that is part of the production cycle of a building that presents this constructive method. Therefore, the research first intends to contextualize the current global scenario of civil construction, so that the use of wood as a sustainable structural solution can be justified. Next, it is defined what mass timber products are, and how they can contribute to the implementation of construction systems based on timber structures and their possible applications. Consequently, the construction systems used are characterized, as well as the procedures for the construction of multi-storey timber buildings, considering besides structural factors, performance criteria such as thermal and acoustic insulation, fire safety, protection against humidity and stability of the buildings. Finally, an analysis of the construction process of three case studies was carried out in order to consider the different possible approaches to projects of multi-storey timber buildings, being them: Brock Commons, located in Vancouver; Stadhaus, located in London; and LCT One, located in Dornbirn

Este trabalho trata sobre a relação do córrego da Servidão com a cidade de Rio Claro. Para entender melhor o contexto histórico analisou-se o papel da água na formação do ambiente urbano e quais são as normas e legislações vigentes que norteiam esse processo. O objetivo é propor a revitalização do córrego da servidão, para trazer a memoria da água como paisagem e qualificar a ambiência da Avenida Visconde do Rio Claro. Este trabalho foi desenvolvido a partir da revisão bibliográfica das ideias de Gorski (2010) e Tucci (2005) que tratam sobre o contexto brasileiro em relação à água e sustentabilidade, em conjunto com Bonzi (2017), Cormier; Pellegrino (2008) e Davis (2017) que defendem o uso da infraestrutura verde como método de drenagem. Na busca de conectar a sustentabilidade com um método de desenho urbano é analisado Rogers (2012), que defende não só a sustentabilidade e suas demandas, mas a necessidade de um desenho urbano voltado para as interações humanas e caminhabilidade. Com isso, Gehl (2015), Speck (2017) e Jacobs (2017) são introduzidos para falar dos possíveis contatos humanos gerados com esses novos desenhos que privilegiem o pedestre em relação ao automóvel e suas dinâmicas. Assim, conclui-se que é possível, a partir de um desenho urbano que concilie o bem estar das pessoas com a adoção de infraestrutura verde, resolver problemas de drenagem e proporcionar vitalidade urbana na área.

This project presents the steps developed by Metalquip to analyze, plan, develop and application an innovative solution for preventive / predictive maintenance of agricultural machinery and equipment, as well as the process of creating a corporate spin-off to take advantage of the identified opportunity. The work follows the technological report protocol proposed by Marcondes, Miguel, Franklin and Perez (2017), starting from the generation of the idea, pre-validation of the solution with clients, followed by procedures for internal approval with the board, approval of the budget for the pilot project development, patenting of the solution: as a utility model - BR 10 2018 010513 2, creation of the spin-off company and an action plan (in execution) for project implementation. The project's contributions include the development and application of an innovative technological solution for the Brazilian market, providing productivity gains for sugar and alcohol plants, with potential for expansion in other sectors of industry such as mining, construction, oil and gas and aviation. The solution encompasses not only results in terms of technology and business development, but also brings environmental benefits, by reducing oil leaks in the field. It is also understood that the project portrays a peculiar but potentially replicable reality for other industries of industrial components, adding important learning that can serve as a reference for entrepreneurs and academics.

The Bolivian immigration to Brazil is a functionalist paradigm that takes place through the assumption that society has a concrete scenario of the Bolivian stereotype enslaved by the textile industry. What few studies bother worrying is that this Bolivian is not inserted in Brazil only as a single subject, but as an individual who brings along, in most cases, his or her family, and therefore begins to interact socially and culturally with all the Brazilian system. Within this scenario, this study aims to analyze the speech of Bolivian students from public schools in the east of São Paulo, understand their feelings and multiculturalism expressions for being in a land so distant from their own. It also aims to analyze the context in which these students are really inserted, observing the treatment dispensed by colleagues in the school context, like it is said by Gadotti (2000) and Freire (1997) the school is a way to demystify any existing prejudice in the community and insert the individual socially and culturally into the society, due to the fact that the school institution is the first place where the inclusion or exclusion can happen and prejudice takes place, but at the same time, it can be banished. With this study we concluded that, despite most of the interviewed students follow on their parents patterns as workers of the textile industry, some of them feel like Brazilians for having been lived most of their lives in the country, and don t feel big differences among their colleagues treatment, trying to insert themselves in the Brazilian context, in a certain way, denying their roots. While others, due to family conflicts and difficulties faced not only in their original country, but so as in their current country, have huge adaptation difficulties and problems to relate with the context, so they don t feel like Brazilian nor Bolivian. Despite these problems, teachers that were supposed to have a part as inclusive educators, end up not helping these students because of their own frustrations within the educational area. We have also observed that, when it comes to the city of São Paulo, all the interviewed students see the city as a well of opportunities in comparison with their country of origin, pointing out the leisure and the shopping activities the city offers, not so possible in Bolivia.

Em sua trajetória única no universo televisivo brasileiro, a Antiga MTV Brasil foi responsável por inúmeras realizações que a identificaram desta forma. A partir de uma dessas produções: um episódio do programa Fim de Semana Especial, voltado ao desenvolvimento do Rap Nacional nos Anos 90 (tema recorrente na programação da emissora e negligenciado pela grande mídia), buscou-se estabelecer um diálogo entre a atividade jornalística da MTV com elementos clássicos das Teorias do Jornalismo. Em primeira instancia, destrinchamos o material escolhido expondo suas características estruturais, seu contexto de produção e seu conteúdo em si. Com os resultados deste processo, objetivou-se, ao mesmo tempo, encontrar o valor jornalístico e simbólico do produto audiovisual em questão. Trabalho este, possibilitado através da variação das bases teóricas utilizadas conforme a alteração dos aspectos estudados. Ora mais prático, ora mais teórico. Averiguou-se, de maneira qualitativa, que o próprio desenvolvimento intelectual e reflexivo possibilitado pela tentativa de estabelecer uma ligação entre as teorias clássicas e um jornalismo mais experimental e próximo a contemporaneidade, comprovou, por si, o inestimável valor jornalístico da obra estudada.

Sol-gel-obtained pseudoboehmite, an aluminium monohydroxide, is a poorly crystalized, non-metallic, synthetic, inorganic nanomaterial with both high purity level and specific area (SA). Studies are currently beeing carried in order to use it in the controlled liberation of drugs. Drugs of controlled delivery aim at releasing therapeutic dosages of a drug to a certain area of the body, keeping the desired concentration, release speed and adequate retention time as well as maintaining optimal blood levels, thus avoiding, on plasmatic levels, the problem of toxic doses. The present work seeks to obtain Pseudoboehmite of high purity and specific area, key characteristics for its use as support to controlled release of Acyclovir. To this purpose, it is essential to control all variables of the process so that the resulting product displays characteristics such as high performance, process reproducibility, continued stability and consistent physical-chemical properties. The variables to be controlled during synthesis are: raw materials, precipitation technique, reagent content in the reaction radium, precipitation temperature, agitation of the reacting medium, aging condition and specially pH control. Pseudoboehmite nanoparticles were obtained through sol-gel process using aluminum chloride hexahydrate in sodium chloride solution as a precursor and sodium hydroxide. The synthesized samples were characterized by X-Ray Diffraction, Scanning Electron Microscopy, Thermogravimetric Analysis, Differential Thermal Analysis and Adsorption Isotherms, observing the variations in the resulting phases and their relations with the variations of the molar concentrations. The Acyclovir adsorption with the synthesized pseudoboehmite was tested in solutions simulating its dissolution in the gastric juice in HCl 0,1 mol/L (pH 1-2) solution and plasma absortion in the simulation of the intestinal system (H2O and pH 6,5-7,5) and characterized by High Performance Liquid Chromatography. Results show that samples synthesized from 0,5M OH- had characteristic peaks in the X-Ray diagram of the pseudoboehmite structure (boehmite), while samples synthesized with smaller molar concentration (0,4M OH-) had peaks characteristic of the bayerite and boehmite structures. Synthesized samples of 0,5 M de OH- concentrations had specific area greater than 139m2/g on average. We noticed that the sample aging reduces mass loss in 36% on average, as seen in the Thermogravimetry (TG), in the samples and that it is also responsible for 46% increase, on average, of the pseudoboehmite sample in the crystaline phase. The adsorption isotherms show that the non-aged samples had a specific area 106 m2/g bigger than that of non-aged samples. The effects of these results can be seen in the answers regarding the pseudoboehmite study as excipients in the controlled release of Acyclovir, which kept its chemical stability without degrading the pseudoboehmite or drug, rendering the solubilization of the drug.
