This research analyses the relationship between the creation and development of the São Paulo Municipal Transport and Traffic Council (CMTT-SP) and the June 2013 Protests. Given the proximity of the Protests with the creation of the CMTT and the similarity of the themes, we analyze the complexity of the interweaving of participation, linking the causes and actors of the June 2013 Protests to the participatory institution. This research uses as theoretical basis neoinstitutionalism, deliberative democracy and participatory democracy theory to understand the definitions of institutionalized participation, extra-institutional participation, participatory institution and institutionalization of participation. Also, we situate the concepts in the Brazilian democratic reality, establishing the links between a modality of street protest and the development of an urban mobility policy management council. The research is a case study and adopts a qualitative approach, delimiting as the period of analysis from 2013 to 2017, during the Protests and the creation and development of the CMTT, until the change of city mayor. To answer the proposed objectives we analysed the councils documents, news that contextualized the performance of the actors and legislation related to transportation and urban mobility. We also did semi-structured interview with council members and with members of social movements related to mobility, especially the Free Pass Movement (MPL), indagating on their participation in Protests and in the CMTT. Data analysis showed that the Municipal Transport and Traffic Council held important discussions on urban mobility, allowing the representation of groups that would not have voice if this space did not exist, mainly for the elaboration of the Municipal Mobility Plan. The institutionalization of participation, adopted by the Haddad government by street pressure in June 2013, although there was already a legal need to create the CMTT, proved to be fundamental for the defense of public transport, because there are conflicting interests in the delimitation of public transport space. Although the MPL has formally refused to participate in the Council, some members follow the discussions indirectly. We conclude that there was a very complex relationship between the Council and the June Protests. The themes, the logics of action and the discursive repertoires of the Manifestations appeared at various moments in the Council's trajectory, evidencing the interweaving between the two participatory processes and proving the hypothesis presented in this work.

The soil harbors great microbial diversity which remains unknown, as regards species, microbial groups and functions in the ecosystem. Among the known microorganisms that inhabit the soil, one group is described as beneficial to agricultural activities: the plant growth promoter microorganisms (PGPM). They are able to aid the development of plants through, mainly, the production of phyto-hormones, nutrients solubilization and control of phytopathogens. Among the PGPM, yeasts present slight prominence, because they are in less quantity in the soil. However, studies in the literature indicate that this group presents great potential, as it presents excellent results in in vitro experiments, regarding the main mechanisms of stimulus to plant development. Considering the above, the objective of this work was to evaluate the germination, initial development of seedlings, seedlings and adult lettuce plants inoculated with the rhizosphere yeast Torulaspora globosa and its metabolites. Two experiments were realized; the first consisted of the inoculation of seeds and lettuce seedlings of the Crocantela variety under greenhouse conditions, germinated in substrate and transplanted to the field. The second experiment consisted of evaluating, under laboratory controlled conditions, the action of yeast, its metabolites and tryptophan on germination and initial development of lettuce (Crocantela and Valentina varieties). Finally, the action of the diazotrophic bacterium Azospirillum brasilense, alone and co-inoculated with the yeast, was evaluated in the development of the Valentina variety. The results showed that for yeast and field trials, yeast inoculation provided seedlings with a lower root length, despite a higher root mass (smaller and more branched root system). The leaves appeared wider and longer, which was reflected in a larger mass of the aerial part. The evaluation of the plants at the post-harvest showed that for the variables height, leaf number, leaf length and width, and fresh weight of shoot, the noninoculated treatment had statistically lower values. The results for the trials under controlled conditions showed that the treatment of the seeds of the cultivars Crocante and Valentina did not affect significantly the germination. The seedlings, however, of the Crocantela variety showed roots smaller and with less area when treated with the yeast and its metabolites. The metabolites of the yeast with tryptophan (T7), in turn, provided a larger root diameter. The data obtained by the Valentina variety showed that the treatment with yeast, its metabolites and addition of tryptophan (T5) provided the best results, especially for volume, root area and number of root tips. The treatments with tryptophan addition (with yeast (T6) or metabolites (T7)) presented the least satisfactory results for the development of the seedlings. It was possible to observe that the treatment 5 also showed the best in stimulating the production of root hair for the Valentina variety. The addition of the A. brasilense, isolated and in co-inoculation with the yeast, did not promote significant growth of lettuce seedlings of the Valentina variety. From the data presented we can observe that the inoculation of the seeds and seedlings with the yeast showed to be efficient in the promotion of lettuce growth. Studies related to inoculation methods, inoculum formulations, cell concentrations and chemical analysis of the metabolites produced, however, are imperative to optimize the results of growth promotion and the establishment of the technology.

Environmental problems have sparked concern about the future of the planet and the living and survival conditions of future generations and other living beings, due to a series of alarming and increasing impacts, including pollution and climate change that have caused the lack of water in several places. With this, the environmental perception and the relation of the human being with the water have become the object of study of several researchers. Another worrying issue is the increase in the number of individuals living on the streets and the relation they establish between themselves and their environment. Education has the potential, in working with the general population, to contribute to the search for solutions to these social and environmental problems. Therefore, the present research aims to know the relevance of activities in environmental education for the formation of ex-homeless individuals from the city of São Carlos, in the interior of São Paulo. In the research was adopted the Methodology of Communicative Research that has as one of its objectives to change the self-image of the participants, generating transformations in social and cultural relations with their environment. This is part of the concept of Dialogic Learning that aims to overcome the different types of social segregation through rigorous principles, based on Freire's dialogicality and Habermas's communicative action. The participants of this survey were thirteen men, ex-homeless, living in a religious NGO, which shelters and assists men to leave their lives on the streets and participate in MOVA group, in which the author of this research is an educator. In the first part of this work, an in-depth interview was conducted with the participants, to know their environmental and water perception, and then proceeded to a communicative discussion. The speech of each one was analyzed in parallel with the perceptions of riverside individuals from Cachexia de Emas and urban individuals from the city of São Carlos, presented in previous work. In the second part, successful communicative activities were carried out, called interactive groups, reanalysis of the interview and communicative discussions. The activities of the interactive groups were planned based on the students' perception of water and based on theory of complexity, focused on education, in which the activities sensitize the learners and lead them to know all the areas that involve a thematic. In the case of this research, the subject selected by the students was the water issue in the Coreg do Gregório watershed, in São Carlos-SP. The speeches were analyzed according to the following categories: "use of water resources" and "access to water", and were subdivided into transformers and obstacles. It was concluded that individuals, ex-homeless, have a perception of the water that approaches both the riverside and the urban individuals due to their existence, experience and culture. And also, those used here to deal with environmental issues, particularly water, using the concept of Dialogical Learning and, together with a complex approach, help in the development of critical thinking in order to overcome injustice in social relations and degradation in relations with the environment.

Information about vegetation biophysical parameters can be used in many applications, and remote sensing is showing itself to be a good tool to obtain it. In this study we investigated the possibility of using Sentinel 2 images to estimate vegetation biophysical parameters measured in field and with LiDAR (Light Detection and Ranging). The study was conducted in areas covered by Atlantic Forest in the state of São Paulo (Brazil) using three Sentinel 2 images. Additionally, we used a Landsat-8/OLI image for temporal proximity with the LiDAR data, tested the effect of topographic correction on the images and made an analysis of leaf reflectance in lab. The analyzed field variables were height, DBH (Diameter at breast height), percentage of canopy cover, and number of individuals. The LiDAR variables were height of the first returns, height of the last returns and number of returns per pulse. A total of 26 variables were extracted for comparisons with the images through OLS (Ordinary Least Squares) and RF (Random Forest) regression models. These comparisons were made with single bands, the vegetation indices RVI (Ratio Vegetation Index), NDVI (Normalized Difference Vegetation Index), SAVI (Soil Adjusted Vegetation Index), EVI (Enhanced Vegetation Index), NDWI (Normalized Difference Water Index), NDI45 Normalized Difference Index B4 and B5), IRECI (Inverted Red-Edge Chlorophyll Index) and S2REP (Sentinel 2 Red Edge Position), and with all the possible rations between two bands. The results show that many biophysical parameters are related to the images (r² up to 0.62), and the topographic correction seems to have a positive effect in the estimates, especially for LiDAR derived variables. The best models generated with field data were regressions between multiple Sentinel 2 bands and tree height, canopy cover and biomass. For the LiDAR data, the results were in general better than with field data and also involved regressions with multiple Sentinel 2 bands in comparison with canopy height and cover. Among the images, the one that presented better relations with the biophysical parameters were Sentinel 2 image of December 26, 2016. The validation results of the LiDAR models show that they work in different areas of the same image in which they were trained but can only be applied in different images after an appropriate atmospheric correction. In general, vegetation indices did not show better results than individual bands. Among the bands, we highlight the role of B5 (705 nm, red-edge) for the success of many estimates, which is confirmed by the results of the analysis of leaf reflectance made in lab. For future studies, we recommend better investigation of wavelengths close to 705 nm and the potential of Sentinel 2 band 5. For the creation of models that can be used in different images, we recommend the use of level 2A Sentinel 2 imagens (surface reflectance), that will be available globally by the end of 2018. Finally, we also recommend to consider other variables such as classes of successional stages and the comparison of Sentinel 2 imagery with other phytophysiognomies.

The Union of South American Nations (UNASUL) is an international organization made up of twelve South American countries, made official in 2008, and is seeking a process of regional integration, in which the economic factor is not the central issue, but treated in conjunction with policies social policies. One of the main goals of UNASUL is energy integration. In this new international geopolitical dynamic, UNASUL faces the great challenge of aligning integration with energy transition, preserving resources and promoting the transition to a low carbon economy. Once established the role expected by this entity in the face of regional and global energy demands, level of participation of renewable energies within these negotiations is investigated. The main objective of the work was to investigate the regulations for renewable energies planned for the energy integration of the UNASUL countries, and how the South American Energy Treaty (TES) contributes to the energy transition of the region. The intention is to demonstrate the hypothesis that the sustainable development proposed by the entity will not occur without implementation of policies and legal norms for the immediate energy transition and future consolidation of renewable energies in the member states. Environmental problems such as the climate crisis, mitigation processes and the potential of renewables for the achievement of sustainable development, as well as the dangers of not promoting these forms of energy use, are described in the course of the work. It deepens for a discussion on the need of public policies for the effective promotion of renewable energies, exposing two examples of success, Chile and Germany. Next, it is investigated the essentiality of the renewable policies being worked in a broad context, taking into account the contiguity of environmental resources and the intermittence in their energy functions. At this point, UNASUL's proposal is presented, and energy potentials of each country are described, stressing complementarities, challenges and insecurities. Potential for energy security and efficiency, as well as for socioeconomic development are demonstrated, showing the increase of employment, poverty and inequalities decreases, and the potential for a more equitable distribution of the assets and liabilities of energy. After reviewing all the renewable regulations in each country, describing the main instruments for promoting new technologies, normative frameworks were drawn up, gathering the main information and data collected. From this, correlations and comments on similarities and normative discrepancies are presented, in order to contribute to a future legal harmonization. Finally, it is discussed the plausibility of the planned TES in promoting the regional integration in a sustainable way and in keeping with the objectives and propositions of the entity. The implications of the TES regulations for integration are exposed, concluding that there is no prospect of energy transition processes to occur if it is taken as planned. It is proposed and discussed new understandings on the right to energy, beyond mere access, raising it to the category of fundamental human right, describing and commenting on new principles, legal institutes and the current themes of democracy and energy justice, as an essential way of achieving the ideals of equal rights and life with dignity.

Competitive Intelligence (CI) is an expanding topic in organizational, business, business, and current literature. Understand by many authors as a process composed of phases that constitute a systematized cycle, which are, in general: Identification of Needs, Planning, Collection, Analysis and Dissemination and Evaluation. Thus, CI has become a great ally in the decision-making process and decision making of organizations and companies, for having information analyzed to respond to organizational needs. Likewise, the use of Information Sources for studies of HF is of paramount importance, since HF works with different types and forms of Information Sources that accompany it in its process and help to respond to its informational, organizational, etc. demands. The Brazilian Institute of Geography and Statistics (IBGE) is a very important information dissemination organization that presents a great variety of Information Sources that portray Brazil in the social, economic, market and technological branches. From this perspective, this research presents as its general objective, to investigate IBGE's sources of information in the context of Competitive Intelligence, in order to understand if this institute, as the largest information provider in Brazil is being used in CI works and if these sources have potential to be used in CI. This research had a qualitative and quantitative approach. Carried out an exploratory and descriptive study, with a bibliographical and documentary survey. Thus, the existence of research groups in CI, the various data and information contained in the IBGE that has possibilities of use in CI, and the investigation of the Intelligence work were identified, although few are found in the SCOPUS database used IBGE as a source of information. The aim of the research was to raise awareness about the use of IBGE information as a source of information for the CI regarding the generation of new concepts and strategies of action based on the understanding of the variables understood by the competitive environment.

The last stages of a genetic breeding program are characterized by the conduction of multi-environmental trials (MET) aiming at the correct selection of promising genotypes in relation to characters of agronomic-industrial interest, such as stem production. Multi-environmental trials are characterized by the evaluation of a group of genotypes in different production environments in order to identify that have greater genetic stability and adaptability. Under these conditions, quantitative genetics studies, such as quantification of the coefficient of repeatability and interaction between genotypes and environments, have the potential to reveal information that can assist the breeders involved during the breeding stages. Considering three populations of sugarcane breeding, the present work aimed at quantifying the coefficient of repeatability to infer the representativeness of the data obtained for each genotype along the numbers of repetitions and / or cuts and their relation to quality experimental; and to develop a study of the triple interaction between genotypes, environments and harvest years through the generalized GGE analysis methodology for three factors context, with the aid of the Tucker3 decomposition. Among the results, the coefficient of repeatability showed a significant and negative correlation with coefficient of variation and that the coefficient of repeatability was not associated with production environments, especially by the classification presented by Prado et al. (2013), whose foundation is based on water availability and soil characteristics. For the analysis of genotypes, environments and local interaction, it was concluded that, when studying the sites, the grouping converged to the Koppen-Geiger climatic classification; and for the cut factor a contrast of selection between cane plant and harvests was detected.

Metallic glasses alloys are a relatively new class of materials characterized by the absence of structural long-range order. During heating, these alloys exhibit a glass transition at a temperature (Tg) before reaching the crystallization temperature (Tx). Within this temperature interval (ΔTx = Tx - Tg), they behave as a supercooled-liquid and their viscosity decrease around 6 orders of magnitude compared to the value observed at room temperature. This feature opens up possibilities for consolidation of atomized powders with amorphous structure when it is carried out within ΔTx. In this sense, the present work aimed to study the fabrication of bulk parts of Fe43.2Co28.8B19.2Si4.8Nb4 metallic glass by a combination of gas atomization and hot extrusion. Two gas atomizations were carried out by means of a modified spray forming equipment. Due to the availability of an ingot of the Fe43.2Co28.8B19.2Si4.8Nb4 alloy produced from elements of commercial purity, this material was used for the first atomization. Subsequently, an ingot was produced using high purity elements in a vacuum induction furnace and it was used as feedstock for the second atomization. The atomizations were not able to produce powders with 100% amorphous structure, but produced powders with proper particle size and morphology to be used for consolidation experiments. The powders were deformed within their supercooled liquid interval, producing samples with a diameter of 7.5 mm. The particles were highly deformed, suggesting that they underwent a homogeneous deformation. However, cracks were observed in the samples. The crystalline fraction in the extruded bodies was similar to that observed in the powders.

The creation and strengthening of the Federal Institute of Education, Science and Technology of São Paulo are part of a package of developmental measures adopted for the implementation of public education policy. After a few years of implementation of the São João da Boa Vista Campus of the IFSP, it was noticed the need to strengthen its relationship with the local and regional community. Thus, the project "IFSP: Conheça-nos!" has been implemented from 2015 to 2016, which combines the university extension to public communication, in order to inform the services offered by the institution and to relate to its public. It happens that after two years fulfilling the objectives proposed and generating positive results, the mentioned project was interrupted. Therefore, the objective of this work is to identify the motivation of its end and its consequences, trying to propose ways for the continuity of the popularization actions of the school. This is because the discontinuity of the project activities suggests that institutional limits were decisive for its interruption. In order to fulfill the objectives, the present study structured through a bibliographical survey, documentary and secondary data analysis, as well as interviews with representative agents (project members) and participant observation, since the researcher was part of the team. Among societal, organizational and personal barriers, it can be said that all of them contributed in some way to the interruption of the project. However, organizational factors were preponderant to their discontinuity. Issues related to culture and the niches of power existing in the organization were the main cause of the team's discontinuance in persisting with the execution of the activities, thus revealing a serious problem of democratic school management. It can be concluded that the social consequences or impacts that result from this scenario is the perpetuation of a vicious cycle that keeps a public institution impervious to the interests of the community. Since there is no democratization of services, besides opening spaces for individualistic interests, the school institution fails to fulfill its transforming role in society, as provided for in its institutional and legal documents, thus reflecting the country's social development indicators. Finally, it is hoped that this work will contribute to the agenda of empirical research on the Federal Institutes of Education, Science and Technology, as well as on communication in public institutions, reflecting ideas and actions of the area that contribute to democratization of public education policy.
Efeito do nocaute da mitofusina 2 sobre a mitocôndria, o retículo endoplasmático e a mitofagia em oócitos murinos

Mitofusins 1 (MFN1) and 2 (MFN2) are transmembrane GTPases present in the outer mitochondrial membrane and involved in the regulation of mitochondrial fusion. Since MFN2 is also present in the membrane of the endoplasmic reticulum (ER), it is also responsible for regulating the morphology and its interaction with the mitochondria. Thus, there is increasing evidence that MFN2 plays a key role in the regulation of mitochondrial function and ER, as well as the autophagic pathway. However, little is known about its role in the oocyte. Recently, we have observed that the conditional knockout of Mfn2 in murine oocytes (Mfn2-null) does not significantly alter fertility, but results in hyperglycemia in the offspring. Therefore, the objective of this work was to investigate the molecular mechanisms that result in these phenotypes. The effects of the conditional knockout of Mfn2 on the oocyte were evaluated considering the function of mitochondria, RE and the occurrence of mitofagia. For this, we first confirmed the effects of the conditional knockout of Mfn2. Knockout oocytes for Mfn2 were able to develop normally when matured in vitro. Pups from knockout oocytes showed alterations in blood glucose levels in the tests of glucose intolerance and insulin resistance when compared to wild-type oocyte (WT) pups. In addition, we found alterations in mitochondria of oocyte knockout regarding number (WT = 0.061 ± 0.004 and Mfn2-null = 0.037 ± 0.003 organelle / μm2), crests morphology, area (WT = 0.589 ± 0.015 and Mfn2-null = 1.673 ± 0.101 μm2) and contact with RE. However, Mfn2 knockout resulted in decreased lipid content in ovulated oocytes (WT = 13.07 ± 0.96 and Mfn2-null = 9.65 ± 0.64 % of lipid-occupied area of ooplasm). In addition, no evidence was found at the transcriptional level of ER stress. As regards mitophagy, no knockout effect of Mfn2 was observed on the expression of genes involved in this pathway, as well as on co-localization between mitochondria and autophagosomes (WT = 0.65 ± 0.05 and Mfn2-null = 0.53 ± 0.04 AU). Thus, these findings demonstrate that conditional knockout of Mfn2 in the oocyte results in metabolic changes in offspring, most likely due to changes in morphology, function and contact between mitochondria and ER. However, the molecular mechanism by which this occurs still lacks elucidation. Furthermore, we have demonstrated that conditional knockout of Mfn2 can be a good model for the study of the inheritance of metabolic syndromes.

Using a maleic grafted polypropylene copolymer as a compatibilizing agent on a composite with hollow glass microspheres HGM is one way to reduce the mechanical properties decrement associated to the round, hollow, hydrophilic spheres. In this work, the esterification reaction between the PP-g-MAH and hollow glass microspheres was studied, both being present in a polypropylene/hollow glass microsphere composite and have been made by reactive extrusion. The aim of this work is to quantify the yield and efficiency of this reaction and to understand the influence of temperature over these. Results show that both parameters are dependent on both the initial content of PP-g-MAH on the extruder and temperature, and that both increase with increasing the initial content, but decrease with increasing temperature, having the lower temperature the highest yield. A model was created to calculate the maximum content of material possible to graft over the microspheres, and good correlation to experimental data was found. The efficiency was low for all studied conditions, and suggestions on how to improve it were made. It was also possible to observe through SEM the differences between the interface of samples with different reaction yields, also observing the formation of an organic layer over such spheres, confirming the grafting of polypropylene.

The present research presents how the multiple languages that are part of Sandman, by Neil Gaiman, simultaneously construct and reconstruct his work, showing how the gathering of visual and textual is intrinsically interconnected. From the study of ideas and writings by authors like Julia Kristeva, Mikhail Bakhtin, Graham Allem, Claus Clüver, Leo Hoek, Edgar Guimarães, Will Eisner, Scott McCloud, Giulio Argan and Heinrich Wöfflin it will be possible to trace and analyze the performance of the Arts presented in Sandman. This dissertation was divided in three chapters and the content of which one is as follows: in the first chapter there is a presentation of the plot of Sandman, in addition to a survey of the languages present in the work of Neil Gaiman; in the second chapter there is a study of critical fortune related to intertextuality and interdiscursivity. The third chapter will aim to recover what was presented in the first two and from the discussions contained in the previous chapters, to analyze how the multiplicity of languages is constructed. At the end of the third chapter, the final considerations of the dissertation will be presented.

This research focuses on the oxylipins with eighteen carbons, compound derived of polyunsaturated fatty acids, produced by twenty-two species of freshwater algae, one cyanobacteria and three species of plants, with emphasis on green microalgae from the Chlorophyta and Charophyta phylum, and also species of the Selenastraceae family (Chlorophyta, Chlorophyceae, Sphaeropleales). The aim was detected, identified and quantified oxylipins derived from linoleic and linolenic acids produced by microorganisms using High-Performance Liquid Chromatography coupled tandem Mass Spectrometry technique. It was used microalgae from the Culture Collection of Freshwater Microalgae (CCMA-UFSCar), species already classified by classic and / or molecular taxonomy, as well as the species of plants for comparative purposes. For the experiments, the material came from the end of stationary phase. Once the compounds were identified by these techniques, it was tested the possibility of using profiles as diacritical characteristics in a chemotaxonomic approach for formation of hierarchical clusters. The pharmacological potential of these compounds was discussed since they present antibiotic and anti-inflammatory activities. Other possible commercial applications were approached since microalgae revealed their potential value as natural sources of hydroxy fatty acids. No oxylipin was exclusively observed to determinated organism that could represents as species indicator. This condition limits the use of oxylipins derived from C18 PUFAs in the taxonomy of the Selenastraceae family, but even so, these compounds provide complementary information for organisms that may be useful in their identification. There was universality regarding the presence of oxylipins analysed in all the taxonomic groups studied. The strains belonging to Chlorophyta division showed the highest total concentrations of oxylipins. Charophyta algae have a concentration of oxylipins dozens of times lower than Chlorophyta, and similar to concentrations found in plants, which may be related to the evolutionary proximity among plants and Charophyta.

The Purchasing Management plays an increasingly important role at the Federal University of São Carlos (UFSCar), once the responsible team, which also includes the Purchasing Department, works in an integrated way to enable the purchase of a wide variety of necessary items to meet the demands of both administrative areas and the three major pillars of the organization: teaching, research and extension, applied in all existing areas of knowledge at university. However, by being a complex organization, the procedures are changed constantly in order to attend random factors such as new legislation or new technologies leading to a great effort to adjust the government employee of the Academic Departments to this new reality. Thus, the main aim of the is to analyze and propose improvements (stated in the employees’ interview of the academic departments) that can be effectively applied to the UFSCar’s purchasing process. In order to reach this aim were used tools regarding the process management. A qualitative research was conducted by applying case studies as research method besides collecting data from sources as legislation, papers and books, interviews were carried out with selected employees to understand their routine and purchase method process in their respective areas. The areas for the research were chosen according to a non-proportional stratified sample of academic departments of the Center of Exact Sciences and Technology of the UFSCar. Through the mapping analysis of current status purchasing processes and its description, twelve possible improvements were identified among others like stock items management and “price registration minutes”. As a result, instruments and procedures with it consequent adjustments of the mapping macro process flowchart were created. The proposes resulted in, among which, a new future scenario, a practical guide to check the Federal Government Price Panel and suggestions regarding the new functionalities to Enterprise Resource Planning (ERP), which has been developed and used by UFSCar.

This work aimed the synthesis, characterization and electrochemical tests of Pt and Pt-Sb nanoparticle catalysts onto mesoporous carbon applied to glycerol electrooxidation reaction. Specifically, the carbon matrixes were synthetized from Si templates with distinct geometries, giving CMK-3 and CMK-5 3D structures. These structures were treated in O2-free atmospheres at 1173 K for 5 h and after the removal of Si with HF solution (as confirmed by thermogravimetric analysis), the mesoporous structures were attested by Small Angle X-Ray diffraction and a 4.8 and 5.3 nm porous diameters were estimated by nitrogen adsorption isotherms to the CMK-3 and CMK-5 structures, respectively. Pt nanoparticles synthesis onto carbon structures (Pt/C) were performed by direct reduction of chloroplatinic acid (H2PtCl6) with formic acid giving particles with 4.5 nm mean diameters as reveled by transmission electron microscopy. Finally, Pt-Sb/C catalysts were produced by irreversible Sb2O3 adsorption. Pt/C catalysts showed voltammetric profiles consistent with metallic Pt in 0.5 mol L-1 H2SO4 solutions, certifying the synthesis success. In the presence of glycerol, it was observed that the activity to the oxidation happens at potential higher than 0.8 V regardless the carbon support; on the other hand, Pt-Sb/C shifted the reaction onset in ca -0.3 V and maintained this activity under fixed potential (0.5 V). Pt-Sb/CMK-3 depicted the best activity among the synthetized catalysts, providing currents 1.6 and 2.0 times bigger than those in Pt-Sb/CMK-5 and Pt-Sb/Vulcan, respectively.

This work is an action research that sought identify possible contributions of national rock music of teaching History from the work as a teacher in a private school in region of Itapetininga. Music was understood here, on one hand as a product of the cultural industry, from the Adornian perspective; and on the other hand as an important object of cultural mediation linked to socio-interactionist conceptions of Lev Vygotsky. Thus, having main objetive the possibility of use sophistication concepts such as "conscience" and "historical empathy", addressed by John Rüsen and Peter Lee at History tutorship. We sought to analyze the contributions of a didactic sequence developed with students of the first and second year of high school, on the contents "Invasion and Colonization of Brazil" and "Industrial Revolution", having as support the songs "Índios", "Fábrica" and "Captain of Industry"; of bands Legião Urbana and Os Paralamas do Sucesso. Among the results obtained, based on the analyzes by students during the process was possible conclude that work carried out provided for mental formulations among these students who showed involvement with historical agents of other temporalities and relevant conceptual appropriations of historical themes and having music as one of the learning axes. In general, spontaneous concepts were with the aid of the songs transformed into scientific concepts.

This doctoral thesis fits in the studies of the Public Assessment Policies of Basic Education and its main objective is to understand the repercussions of the Brazil Exam in the teaching work for the teachers of the public municipal schools of Cascavel-PR before the contradictions between the large-scale evaluation of the Exam and the municipal curriculum. The research aims specifically to: a) contextualize the economic, political and social conditions in which the Public Assessment Policies were established and implemented, considering the Brazilian Basic Education; b) analyze the development and contradictions of the Brazil Exam implementation in Cascavel-PR, understanding that the work is guided by a curriculum of its own, conceived on the basis of theoretical criticism; c) understand the limits and possibilities of the Brazil Exam to promote the emancipation of the pedagogical work. The study started from the implicated problematization of the Brazil Exam to the teaching work, in the perspective of teachers and education managers of the municipality of Cascavel-PR before the contradictions between the large scale evaluation and the municipal curriculum. It was considered as hypothesis that the demands around the large-scale exams and the limitation determined by the the working conditions and by the way in wich theachers training has taken place, have taken away the meaning of the teaching work proposed by the municipal curriculum. The research methodology is characterized as qualitative. In the data collection procedures, field research and bibliographic and documentary survey were used. Field research was conducted through interviews with teachers, pedagogical coordinators and principals of six municipal schools. Three of these institutions obtained the best IDEB scores; the other three had the lowest IDEB scores, published in October 2016. The bibliographic survey took into account theses, dissertations, articles and books to the theoretical knowledge already developed on the topic. The documentary survey was carried out through consultation of documents consisting in laws, reports, government guidelines, school documents and the teachers syndicate of the Municipal Education System of Cascavel-PR. Data analysis procedures are based on the categorization and triangulation of the different sources used. The results revealed contradictions around the working conditions and of the limits of teacher formation, initial and continuated, wich implicates negatively in the teaching work. The study also reveled potentiality, by indentifying that despite the demands determined by the Brazil Exam the teaching work have not been reduced in school content required by external assessment. There are also positive outcomes that occur when there is participation of the school community in the setting of school goals and in the collaboration to achievement of these purposes. Another positive effect is that the professionals have been defending the implementation of the municipal curriculum although limits are identified both in theoretical and practical comprehension of the pedagogical proposal intended by the document. In conclusion the Brazil Exam have taken away the meaning of the teaching work intended by the municipal curriculum, since it does not consider the limits imposed by the working conditions and by the teachers formation, initial and continuated, in the evaluation process.

In view of the applications of information and communication technology in processes of archival description, interoperability and cooperation between registries, there is a need to re-evaluate the internationally recognized standards of archival description. To this end, the International Council on Archives proposes Records in Contexts, a conceptual model of archival description identified as RiC-CM. Faced with the question "where in the RIC-CM meets archival description requirements according to public consultation the archival community?" the general objective of the research is to explore the adherence of the RiC-CM to the archival description requirements indicated by the archival community and to examine the conceptual, methodological and practical aspects of the archival description; explore the RiC-CM; analyze the AtoM software; evaluate the manifestations of the archival community in response to the public consultation with RiC-CM. As methodological procedures, the qualitative approach is applied, with an exploratory and descriptive purpose and uses bibliographic and documentary procedures. As a result, the RiC-CM needs a considerable amount of adjustments in the approaches to methodology, project development, inclusion, transparency, comprehensiveness and technology, although the ICA initiative proposes a fill a gap regarding the standardization of archival description be commendable. It is understood that the RiC, despite all the criticisms, is making possible a discussion about the current ICA norms and awakens to the necessity of having a standard that, at world level, meets the needs of archivists, regardless of language or country, and which aims at the application of the linked open data.

The steel-concrete composite columns are characterized by the combination of steel profiles and structural concrete to form a single, tough section. Among the composite columns, the one of the filled type stands out, characterized by the filling of the tubular profile of steel by concrete. In this system, the combination of steel and concrete aims to take advantage of the good characteristics of these materials in a single structural element besides imparting speed of execution, flexibility, freedom in structural design, lightness, compatibility with other materials and rational use of materials. In this context, the present work presents the development of a methodology for numerical analysis of the square concrete filled steel tube composite columns under eccentric loads. For the modeling, the software ANSYS® was used and the numerical model was validated using experimental results. Important aspects of the choice of finite elements, mesh and form of force application, as well as the constitutive models of steel and concrete were discussed. After validation, the numerical model was used to evaluate the influence of the yielding strength of steel and the concrete compression, eccentricity of the applied force and slenderness ratio in the load resistance and the behavior of the concrete filled steel tube column. The analyzed parameters revealed a direct influence on the behavior of the concrete filled steel tube column mainly in terms of load capacity and rigidity. Comparative analyzes of all parameters allowed observations on the most important variables.

The aim of this study was to analyze the spatial distribution of suspected cases of Dengue Virus (DENV), Chikungunya Virus (CHIKV) and ZIKV Virus (ZIKV) and the relationship with socioenvironmental indicators of the city of São Carlos-SP. This is an ecological study with multiple measures of analysis. Secondary data from the Information System on Notifiable Diseases (SINAM) were used in the period from 2016 to 2017, in addition to data from the Brazilian Institute of Geography and Statistics (IBGE) of the last Demographic Census of 2010. The data were obtained after approval by the Research Ethics Committee of UFSCar. Descriptive statistics of the diseases were performed, followed by a bivariate analysis of the sociodemographic variables and their relationships with the independent variables (scholarity and race). The construction of the social-environmental indicators was processed using Statistica software version 12.0, using the Principal Component Analysis (PCA) technique. The suspected cases geocoding was achieved by exporting the Excel tables to Google's Fusion Tables. After the geocoding of the addresses by Fusion Tables, the list was imported to Google Earth Pro .The generation of thematic maps was performed by Arcgis software version 10.5. In 2016 and 2017, 4552 and 1114 suspected dengue cases were registered, respectively; 118 and 71 suspected cases of chikungunya and 59 and 8 suspected cases of zika.The arboviruses predominated in female patients, being dengue, 52.99% in 2016 and 49.82% in 2017; to chikungunya 70.34% in 2016 and 57.75% in 2017; and for zika 67.71% in 2016 and 62.50% in 2017. Regarding the age group in the analyzed period, 37.5% of the suspected cases of DENV, 38.6% of the suspected cases of CHIK and 62.7% of the suspected cases of ZIKV were concentrated in the age ranges of 21 to 30 years and 41 to 50 years.The bivariate analysis showed the highest rates of DENV, CHIKV and ZIKV in people with complete high school, incomplete higher education and complete higher education. In 2016, we highlight the highest rate of suspected cases of dengue, 290.94 suspected cases/10,000 inhabitants. registered in the Center weighting area; The Cidade Jardim weighting area had the highest rate of chikungunya, with 10.95 suspected cases/10,000 inhabitants. and also the highest rate of zika with 19.12 suspected cases/ 10,000 inhab. In 2017, the highest rate of dengue was reported in the Cidade Jardim weighting area with 52.91 suspected cases/10,000 inhabitants; The Jockey Club weighting area presented the highest rate of chikungunya and zika with respectively 7.66 suspected cases/10,000 inhabitants. and 1.41 suspected cases/10,000 inhabitants. The results showed high rates of suspected cases of arboviruses in weighted areas with appropriate social conditions and reduced rates in weighted areas with social. It was concluded that the profile of suspected cases of dengue, chikungunya and zika in the population of São Carlos – SP is not related to low socio-environmental indicators and that population dynamics and mobility related to the high flow of university students may influence the pattern of spatial distribution of arboviruses in the municipality.
