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.

Most Brazilian universities employ traditional teaching-learning methodologies based on lectures classes. The Federal University of São Carlos (UFSCar) is not an exception, but some of its programmes employ active learning methodologies, such as Problem Based Learning (PBL). The Ubiquitous Computing Group (UCG) of UFSCar, which was established in 2002, has been developing projects focused mainly on the Education and Health areas, and recently coordinated the development of the project Educational and Academic Management System for Courses Based on Active Learning Methodologies (EAMS-CBALM). The Scrum agile method was employed in the EAMS-CBALM development, with periodic meetings involving developers and Product Owners (POs) for planning and analyzing the different EAMS-CBALM development phases. It was quite often necessary to redefine some system behaviour scenarios, due to ambiguities present in requirement specifications, or due to misinterpretations of stories reported by POs. The definition of test suites was also cumbersome, resulting in test suites that were incomplete or did not at all comply with the system requirements. Based on this experience and to deal with these problems, this work proposes the ScrumOntoBDD approach, which combines Scrum, Ontology and Behaviour-Driven Development (BDD), for agile software development. This approach explores the concepts and techniques of SCRUM and BDD, focusing on the planning and analysis phases of software life cycle, since the BDD tools provide little support to these phases, and most of the problems found in the EAMS-CBALM development were in those phases. ScrumOntoBDD employs ontologies in order to eliminate ambiguities intrinsic to the use of a natural language as a BDD ubiquitous language.

Brazil is the third largest producer of corn in the world. The high yield obtained in maize is a result good plant development during the crop cycle, supported by good water availability in the soil and best management practices, resulting in effective plant nutrition and control of insect pests and diseases. Diabrotica speciosa stands out as an important insect species causing significant damage to the plant roots consequently reducing the absorption of water and nutrients. It is reported as key corn pest in Brazilian southern states and some areas of the Southeast and Center-West. Its impacts might cause yield losses ranging from 10 to 13% under high infestation. Some methods of control might be used to reduce pest infestation and consequently the damage caused by the insect such as chemical control, transgenic plants and biological control. An alternative potential method could be to induce plant resistance with silicon (Si) through plant nutrition. Studies have shown that Si can stimulate plant growth and yield, as well as confer protection against abiotic factors, such as aluminum toxicity and water scarcity, and against biotic stress such as diseases and insects. Therefore, the hypothesis of this work is that Si also promotes modifications in the anatomy and morphological characteristics of the root system leading to an increased resistance against D. speciosa in maize plants. The project was conducted under greenhouse conditions, in a 2x2x2 factorial scheme: two maize hybrids, two quantities of silicon and two degrees of infestation by D. speciosa (with and without infestation). The attributes plant height, dry mass (root and above ground), Si content (root and above ground), root injury caused by the insect and anatomical characters of the root system were measured and submitted to analysis of variance and to the comparison test of means of Tukey to 5%. The higher availability of Si did not impact the plant biomass production (root and above ground). Si can induce modifications in the anatomy of the root system. By the other hand differences were found between maize hybrids. The HY01 hybrid showed a natural higher degree of resistance to D. speciosa larvae, potentially conferred by better root development and higher deposition of suberin in the exoderm, since this compound stimulates defense enzymes against herbivory. Based on these results, we conclude that under these tested conditions the application of Si did not promote resistance to D. speciosa larvae

Biological invasions are common. Riparian zones are among those that undergo major biological invasions. The accumulation of biomass and necromass interferes in the dynamics of the plant community in a significant way. Considering the potential harmfulness of invasive species, it is interesting that we think of forms of control. Our objectives are to determine if: 1) biomass and necromass production of Hedychium coronarium, Urochloa decumbens, Melinis minutiflora and Pennisetum purpureum are related to climatic variables, 2) the net primary aerial production of H. coronarium, U. decumbens, M. minutiflora and P. purpureum throughout the year, 3) to test the effect of once and twice-yearly cutting of H. coronarium ramets on their growth 4) to test the effect of H. coronarium rhizome cutting off once a year, 5) to test the effect on growth of H. coronarium with injection in its rhizomes of alcoholic extract of Typha dominguens in two concentrations (5% e 10%) and from leaves and rhizome, 6) to test the effect on growth of H. coronarium with injections of glyphosate into its rhizomes and 7) with spray of glyphosate on its leaves. Our hypotheses are 1) the production of biomass and necromass will be related to climatic variables, 2) the net primary aerial production of all species will be high in the year of study and 3) there will be effect in the growth of H. coronarium with the application of the treatments. For one year we collected monthly aerial biomass and necromass of the four species. To calculate net primary aerial production, we used Smalley’s method. We tested the data for normality using Shapiro-Wilks test. Relations among climatic variables were tested with Spearman’s test. Variables not related to each other were tested with a mixed linear model (GLM) in its relationship with climate. To select most adequate model of explanation, we used AKAIKE test (AIC), within R environment. For mechanical control we established three plots in five sites subdivided into four sub plots: i) control, ii) cutting off ramets once a year, iii) cutting off ramets twice a year and iv) pulling out ramets and rhizomes. For the experiment of chemical control of H. coronarium planted five pieces of 10 cm of rhizomes in aquariums of 30 cm x 30 cm x 20 cm with 5 cm of fertilized soil. Aquariums were kept in a room with 12 hours of light and 12 hours of dark and temperature 24+/-2°C. To test glyphosate injection and spray, we left four aquariums for control, four for injection and four for spray. Injections were made with 10 mL of the product undiluted. Five months after the first injection, we repeated the procedure. To test glyphosate spray, we repeated the application two months after the first spray, and again after four months. To test Typha domingensis alcoholic extract, three aquariums were left for control, three had its ramets injected with leaf alcoholic extract at 5 % and 10 % concentration, three had its ramets injected with rhizome alcoholic extract at 5 % and 10 Once a month, we numbered the ramets and measured their diameter on soil level and the total height for all experiments. To test the differences for height and diameter among treatments, we used linear mixed models. All analysis was conducted within the R statistical environment. We also used mortality rates expressed in percentage of dead ramets. The species studied have a direct relationship with the environmental variables in question and cause great impacts on riparian zone due to its high production of biomass and necromass throughout the year, especially H. coronarium and P. purpureum. Therefore, control measures are of extreme interest. The control experiments of H. coronarium were efficient, treatment with glyphosate injection in the rhizomes of the plant was the one that obtained the best result, with mortality rate of 97,3 %. The locality of H. coronarium should be considered so that there is no mortality of other species when applying the herbicide.

Information Science arises with the transition between modern science and postmodern science, which originated an integrating knowledge movement called interdisciplinarity. By linking to the fact that it has a complex object of study - information, its interdisciplinary inclination is recognized. With the growth of Postgraduate Programs in Information Science in Brazil and consequent expansion of research in the area, it becomes relevant to identify how the interdisciplinary relationships in the area occur. The potential of the Plataforma Lattes in the development of bibliometric studies is acknowledged for providing a legitimate representation of Brazilian science. The objective of this research was to investigate the multidisciplinary profile and the interdisciplinary relations of Information Science with other areas of knowledge. The research method was of an exploratory nature, with a quantitative approach and involved the use of bliometrics and network analysis techniques. The sample analyzed involed 417 Lattes Curricula of teachers linked to the postgraduate programs, from 2013 to 2017 and of 370 co-authors identified in the scientific production of these teachers, comprising the four-year evaluation period of the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), from 2013 to 2016. As a result, it was characterized the multidisciplinary profile and interdisciplinary relations in Information Science, identifying the areas that provide and those that receive contributions from Information Science. It was concluded that the results contribute to instrumentalize the understanding of interdicisplinarity in the scientific activity of the area, and consequently to its strengthening and visibility as an area of knowledge in the Brazilian National Postgraduate System.

The main objective of this study was to understand the contemporary regime of subjectivity in the favelas of Rio de Janeiro, based on the analysis of the processes that involve the pacification of these territories and the emergence of new forms of the market, having as empirical cut, the "tourist favela" and the "Self-management". The pacification project represented a possibility of political and economic management of certain territories chosen according to the strategic objectives defined by the power apparatus. Control, militarized surveillance and the consequent domestication of bodies can not be considered the only forms by which power invested, since pacification also sought to structure a field of action in which the favelado itself was an active subject of its own transformation by the way of entrepreneurship. In this sense, the study sought to understand the process of subjectivation of slum dwellers as something situated in the midst of a complex of apparatuses, practices, machinations and compositions within which they were constituted and which presupposes the implication of particular relations with themselves, the research analyzed how the intersections between a set of devices that propitiated a strategic articulation of the ways of conduct of others with the forms of self-government. In order to elaborate the study, the following areas of UPP were taken as object of analysis: Favela Santa Marta, Favela Pavão-Pavãozinho, Ladeira dos Tabajaras / Morro dos Cabritos and Complexo do Alemão. The methodology used for the purposes of the thesis could be fulfilled consisted in the elaboration of a study based on the qualitative analysis, obtaining data through direct observations and semi-structured interviews. As a result, it was possible to observe that the expansion of neoliberal logic in the pacified favelas, on the one hand, configured entrepreneurship as a possibility for the favelados to find their "place in the sun" and on the other intensified processes related to the individualization of destiny and poor subject, as well as the emptying of the public sphere and collective projects.

Fish of the Schizodon genus have important representation in the largest South American basins. Historically they underwent through several taxonomic revisions, due to their high phenotypic plasticity and the ontogenetic characters found among the species of this group. The goal of this work was to evaluate the congruence between the molecular units (MOTUs) and the nominal species currently valid, using the DNA barcoding and coalescent methods. DNA extraction, amplification and analysis of the mitochondrial COI region from 68 samples were performed; additionally, 19 sequences available on the BOLD system were added to the analyses. The CodonCode Aligner program was used to edit the sequences and alignment. The genetic distances were calculated in the MEGA 7 software, using the K2P model (Kimura 2-Parameters). For the distance-based species delimitation, the DNA barcoding method was used with three different values of thresholds (2%, 1.4% and 1%). Although evidencing different numbers of MOTUs, the results were congruent in suggesting a possible synonymy of S. jacuiensis and S. platae. With the thresholds 1.4% and 1%, S. vittatus was subdivided into two MOTUs, evidencing the existence of a potential cryptic species. These results were corroborated in the GMYC (Generalized Mixed Yule-coalescent) species delimitation analysis. Thus, the findings of this work show that there are disagreements between the molecular units and the currently valid taxonomy for the genus. This indicates that an extensive taxonomic revision, using morphological and molecular tools, which include different genes, is still needed for a better decision on the taxonomic status within the Schizodon genus.

The discussion scenario for Special Education (SE) and Inclusive Education (IE) is a reality today and means that it does not occur only in the theoretical field. The difficulties and challenges are related to different aspects shown by many studies that verify that, unfortunately, exclusionary situations in school everyday. The same scenario is noted when we focus in school physical education (SPE). Therefore, the topic of this research is related to SPE and SE. The general objective is: to analyze the exclusion factors of people with disabilities (PWD) in SPE. The specific objectives are: 1) to describe and study the life trajectory of PWD focusing on lived experiences during physical education (PE) classes at school; 2) to study the relation between SPE of PWD and their involvement with sports; and 3) to analyze the PWD conception of PE. The theoretical framework is based on Dermeval Saviani's Historical-Critical Pedagogy (HCP), as well as EE studies such as Jannuzzi (2004a, 2004b) and PE studies such as Chicon (2015), Darido (2003) and Castellani Filho (2003), which will help to discuss its contextualization, conceptions, purposes and contents. The chosen referential is the thematic oral history, focusing on five axes to conduct the interviews. The selected collaborators are four adult educated athletes, with ages varying from 17 to 63 years, who play in adapted teams in the city of Sorocaba and are already attending school as a disability person. The analysis of the interviews identified and classified the contents that most appeared at the narratives. After that, constructed data was interpreted according to the theoretical framework of the research, pursuing to answer the proposed questions. Finally, it was possible to realize a concrete analysis of the real-life movement of the PWD, considering their past in the SPE, identifying as exclusion factors: 1) the teachers' approach; 2) the dissemination of content without a dialectical interface with the social function of SPE; 3) the fragility in legitimation of SPE’s purposes; 4) the discrimination and society’s difficulty in understanding people instead of judging someone by their disabilities; 5) the unpreparedness in some professionals training. It should be emphasized that it was not intended to assign value judgments to historical moments of the SPE, but to perform a critical analysis to understand such factors, assuming a political position of discussing the reality of PWD in these classes through their own trajectories: “Nothing about us, without us!”. It is expected to contribute with a quality education and encourage further studies focused on educational practices, which prepare individuals to intervene and overcome barriers that are put by society and thus ensure everyone’s right to acquire knowledge and contents about body culture, aiming a truly inclusive SPE.

Precise estimates of energy production and consumption are essential to promote the integration of renewable energy sources to the electrical grid, guiding power supply balance through cycles and fluctuations inherent to these resources. In this scenario, many experiments have developed solar radiation forecasting methods, but not so many of those apply Recurrent Neural Networks and their potential of modeling time series. This dissertation reviews some of the studies and outlines an experiment comparing Recurrent Neural Networks, XGBoost and persistence of Clear Sky and Clearness indexes in solar irradiance forecasts. Model precision is verified in minute observations from Denver and Las Vegas, re-sampled in resolutions of 5 minutes, 30 minutes, 1 hour and daily mean. XGBoost gives the best results in all forecast horizons, with nRMSE between 12.9% at 5 minute resolutions, and 21.2% at daily mean. Persistence models for Clear Sky and Clearness indexes show comparable precision, with nRMSE from 14.2% to 22.5% in forecasts up to 1 hour ahead. RNNs outperform persistence in forecasts of daily mean irradiance, reaching nRMSE 21.3%.

This dissertation addresses the problem of designing a humanitarian supply network. With this purpose, a mixed integer linear programming model is proposed, which aims at maximizing the covering of demand in the affected municipalities. The proposed model considers facilities having two purposes (which operate as deposits and aid centers), and is used to decide on capacity planning upon the basis of the Social Vulnerability Index (SoVI) that prioritizes the care of more vulnerable areas. For the sake of testing the model, a real case based on the Brazilian disaster response planning was considered. Thus, data was gathered from the Integrated System Disaster Information (S2iD); in particular, the 11 types of natural disasters with the highest prevalence during the period 2007-2016 were used for the study. The goal was to estimate the demand for relief aid required to cover population needs in the affected municipalities. Computational experiments were implemented and executed to evaluate the mathematical model. The results suggest that the model proposed may be used as a decision support tool that allows for evaluating: (i) the configuration of the humanitarian supply network, regarding to the deposits and aid centers, as well as their characteristics in terms of capacity and long-term operation, (ii) the dynamics of transportation of relief aid throughout the country to meet the requirements (iii) sensitivity analysis of the budget to the care of victims and the role of SoVI in the level of emergency service; and (iv) the advantages and disadvantages of combining pre-positioning and acquisition of relief aid to take the care of victims.
