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.

The Internet of Things (IoT) is considered one of the emerging technologies in the area of information technology. The use of this technology provides an improvement to the population by providing better transportation systems, health and electrical infrastructure, among others. However, collecting information in these spaces can cause serious damage to the user’s privacy, which is one of the challenges to be overcome by IoT. In some scenarios, the user may provide personal information without being aware of the risks to their privacy. Cryptographic primitives with a high computational cost are used to maintain the privacy of users in IoT environments, but they are not applicable to all devices due to their heterogeneity. In this context, this work proposes a mechanism of preservation of privacy that aims to mediate the information exchanges that occur in IoT environments. This proposal was based on a research done with users that aimed to validate the characteristics and functionalities of a mechanism with these objectives. The privacy preservation mechanism was developed as an application to provide ease in user interaction with IoT environments. The validation of the application was performed by an experiment with the users, where they were submitted to several IoT scenarios. The results show that, with the use of the mechanism, users feel more comfortable with the availability of their data in these environments. The learning process of application privacy preferences obtained a success rate of 88.62% in the predicted scenarios and is considered satisfactory for decision making procedures for the provision of personal information.

This work aimed investigate the perspectives attributed to the teachers about their performance at one daily care in the city of Sorocaba towards the judicialization context of vacancies in the Childish Education. It also aimed to understand the challenges and possibilities of the staff performance since demands provoked by the implications of the judicialization in the daily care center. The study approaches the concept of perspective from the cultural-historic theory of Vigotski (2008). Three teachers of one daily care center have participated in this study, thus having as methodological strategies the participant's observation, records in field diaries and interviews semi-structured. The results show that : a) the judicialization was noticed by the participants as one fact that denotes the incapability of the region to fulfill the legal determinations towards the attendance of the children at 0 to 3 years of age; b) the teachers recognized the law of small children to education, but reinforced (that) the judicialization has produced a few alterations in the school routine and in the educative work, causing situations like the superpopulation of the classrooms, what imposes the necessity of adjustments in the educational attendance offered. c) the reports of the participants signalized that the team has been trying to create alternatives to lead with the existing difficulties, but the living reality is difficult, mainly due to the following aspects : a few human resources, a precariousness work and an increasing outsourcing of the services of the district, through the hiring number of professionals in the daily care centers. They argue that the right of the child to the educational attendance in the daily care center must be guaranteed, as what is recommended in the Law as well as in the official orientations of the Child Education. However there are several challenges to be faced against actual nonliberal polices which include the progressive decreasing of public investments and the outsourcing of services in the field of Education. We can conclude that educators, managers, social movements and communities need to articulate, thus charging from the responsible administrative organs the respect from the children's rights, as well as fight for the improvements in the Child Education attendance in district.

The objective of this work was to evaluate the diversity of Ichneumonidae (Hymenoptera, Ichneumonoidea), with emphasis on the subfamily Pimplinae at three different altitudes in the Serra do Japi Biological Reserve, Jundiaí, SP, Brazil. The samples were collected using malaise traps installed at altitudes of 896 m (A1), 1,082 m (A2) and 1,190 m (A3) in a period of one year (October 2015 to October 2016). A total of 4,196 specimens of Ichneumonidae were collected from 18 subfamilies. Cryptinae, Pimplinae, Campopleginae, Ichneumoninae and Orthocentrinae were the most abundant subfamilies. The highest altitude site (3) showed greater abundance with 1,625 individuals (38.73%); in the other two collection points (A1 and A2) presented greater wealth (18 subfamilies). The subfamilies with cenobiont habits (11) were the most abundant (56.12%). The highest diversity and equitability indexes were found at the lowest altitude; the highest quantitative similarity occurred between the lowest and highest altitudes; the highest qualitative similarity was found between the lowest and intermediate altitude sites. The 745 specimens of Pimplinae were identified in 18 genera and 91 morphospecies. Males accounted for 50.6% and females accounted for 49.4%. The most frequent specimens were of the genus Pimpla (54.23%) and Neotheronia (16.37%). P. caerulea Brullé, 1846 was the most frequent species (43.62%). For Pimplinae, idiobionts were more frequent (530) attributed to 3 genera. The abundance was higher in the lower altitude site, with 293 specimens collected; the highest richness in the highest altitude site, with 56 morphospecies. Higher values of diversity and equitability index for Pimplinae were found at intermediate altitude, and the lowest and highest altitude sites were similar quantitatively; and the intermediate and high altitudes qualitatively. At different times of the year, the highest abundance values of Ichneumonidae and Pimplinae were recorded in hot and rainy periods. A new species was found for the genus Acrothapus and two for the genus Polysphincta. The Serra do Japi is home to important fauna of Ichneumonidae and Pimplinae, which makes it necessary to increase knowledge in this region.

A subject of constant discussions, scientific communication, since the seventeenth century, has been undergoing several changes. One of the most dramatic of those was from the middle of the last century with the emergence of the periodicals crisis, triggered by the explosion of the costs of subscriptions to international periodicals. In contrast, with the advent of the internet, STS studies, and also, the open access movement to scientific publications, new proposals begin to emerge, implying an open science and results available to all. On the other hand, research funding agencies have increasingly demanded that the researchers they fund publish in journals with a high impact factor, many of them, including paid access, generating future expenditures for the acquisition of journals by public libraries. As an example, only in 2017, the federal government in Brazil spent nearly 107 million dollars to maintain the CAPES Periodical Portal. Given the above, the aim of this research is to compare the methods of publication and knowledge dissemination by researchers and professors on the Postgraduate Programs in Exact Sciences (CCET) and Human Sciences (CECH) at UFSCar, and to verify what percentage of this output is in open access. Because it has a quantitative-qualitative research approach, this dissertation is composed of bibliographical research that brings together topics such as the scientific community, as well as communication among peers, their modes of production and scientific indicators. Finally, we discuss some topics relevant to postgraduate studies and the impact of their evaluation system. In the document research we use data from UFSCar, CV Lattes, Qualis CAPES and Sucupira Platform, adopting as a cut-off period the years 2013 to 2016 (last CAPES four-year evaluation). For the mapping of the bibliographic production of the researchers investigated here, we used the ScriptLattes software. With the data tabulated, we consulted which journals were registered in DOAJ and SciELO. For those which were not registered, we consulted the SHERPA / RoMEO database to verify the self-archiving policies of the journal titles identified. Finally, we researched articles from these journals on Google Scholar to see if they had copies available in open access repositories. The research results identified 19 programs, 434 teachers and the publication of 308 complete books, 1162 book chapters and 4638 scientific articles. From these, we find that the PGPs in the Exact Sciences have mostly male researchers, with predominant publication of articles in subscription scientific journals. On the other hand, in PGPs in the Humanities, there are more female teachers, with a higher percentage of publications in books (complete or chapters). Regarding the scientific articles, we could observe the predominance of publications in open access journals for programs in the Humanities. When accessing subscription journal articles on Google Scholar, we find the vast majority of them have open copies available. We conclude that our objectives have been met and we stress the importance of further studies on this theme.

This research aims to ethnographically study the circuits of exchange that are established between incarnated and disincarnated agents in the activities of a spiritist center in the city of São Carlos (state of São Paulo). Through the description of what is done on a daily basis within a spiritist institution, the analysis seeks to apprehend the circuits of gifts and hierarchical processes involved in lectures, psychic sessions, prayers, passes, study groups and charitable practices, focusing on the effects of relationships thus established and its centrality in the construction of the spiritist notion of person. Spiritist practitioners establish their religious experiences around the movement of energies, words, spirits, knowledge, healing, feelings, messages, objects, etc. Such sets of spiritual and material goods constantly traverse the planes of existence (physical and spiritual) and evolutionary layers that make up the kardecist view of the cosmos. This image of the universe is organized in terms of hierarchical levels, a principle that also guides relationships between incarnated and disincarnated actors on Earth. The discussion of these aspects, alongside with a reflection on reciprocity and debt, aims to offer an understanding of spiritism as a system – morally and cosmologically – for circulation, enabling a relational and dynamic perspective of the daily religious experiences in the spiritist center.

The construction industry is the main generator of waste in the economy. The CW can account for up to 70% of total urban solid waste produced (SINDUSCON, 2015), resulting in a concern for the waste of materials extracted from nature, with their illegal disposal and consequent increase in demand for landfill areas. The CONAMA Resolutions and NBR 15.114 (ABNT, 2004c) presented the guidelines for the correct destination of the residues and the development of the CW recycling activity as one of the ways to solve this problem. In addition, Marques Neto (2003) and Córdoba (2010) demonstrated that almost all CW, represented by Class A waste, can be recycled with the production of recycled aggregates. The development of the recycling of CW class A in Brazilian territory was verified in the research of Miranda, Angulo and Carelli (2009) with the identification of 24 units of plants in the State of São Paulo, with only 3 located in small municipalities, with population below 100.000. At the same time, even with lesser generation of waste, they together contribute a significant percentage of CW generation, representing 87.90% of the total municipalities of the State of São Paulo (IBGE, 2010). In this sense, this research had as objective the accomplishment of technical visits based on the content of the bibliographical revision with the proposal of basic project that resulted in the presentation of technical parameters and elaboration of costs for an economic feasibility analysis on the implantation and operation of recycling plants of CW class A, in three case studies defined as small municipalities, with a population range between 10 and 100 thousand inhabitants. The municipality of Severínia with production of 3.70 t / h of recycled aggregates presented the project as not feasible. The municipalities of Monte Alto and Votuporanga, with a production of 6.50 t / h and 13 t / h, respectively, presented as a viable investment with positive net present value and capital recovery.

The industrialized precast building systems have been used all over the world in housing construction since the 50’s. In Brazil, as there were no specific standard codes for precast panels until 2016, the use of those building systems have been under the certification of technical evaluations called DATec from the SINAT system. Since the approval of the new code of practice NBR16475:2017 - Wall Precast Panels and the review of NBR9062:2017, many performance aspects related to structural safety, fire, water tightness, among others are now covered, however there is not yet a very clear position regarding thermal performance requirements. In this context, as specific contribution, this research intends to present the results of an exploratory study regarding aspects and design conditions related to precast walls’ thermal performance, according to the code of practice ABNT NBR 15575 and the precast code of practice ABNTNBR 16475. In order to potentialize a greater usability of those systems in Brazil, this study was accomplished through the measurement of the wall surface temperature using a thermal camera and the comparison of the achieved numbers, verifying the importance of design factors that influence the façade's temperature variation through the solar energy absorption at heat flow, impacting wall panel's thermal performance.

This work aims to document the production process and characteristics of the new Brazilian prestressing steel CP-210 RB, as well as evaluating its use viability and to indicate design guidelines for the application in the design of precast prestressed concrete beam bridges. In this thesis, numerical examples of the design of isostatic reinforced beam are presented considering the use of conventional passive reinforcement and prestessed concrete using either CP-190 RB and CP-210 RB steels. Design procedures consider both full and limited prestessing specifications. Typical, design details are also considered. Comparative studies of materials and execution procedures are considered assessing the bridge deck, designed with several girder beams, for execution of the prestressed or reinforced precast beams. The number of girders and the deck width were determined according to the DER-SP specification for road bridges and overpasses. The beam height varies according to the span length. Designs assessed both the Service Limit State and the Ultimate Limit State considering each construction system. From the analysis results, trend lines were determined indicating the class 450 isostatic precast beams for road bridges production cost, with deck width of 14 m and nominal length from 20 to 35 m, considering solutions in reinforced concrete and CP-190 RB and CP-210 RB prestressed concrete options. With the trend lines, it was possible to determine that bridge or overpass for deck structure with lengths greater than 22 m are economically viable with the use of precast prestressed girders using the new Brazilian CP-210 RB steel. This work also presents, for each chosen construction system, the equations to determine the production cost of precast girder as a function of the nominal length of the deck structure and according to the production items unit costs: concrete, formwork, CA-50 steel, CP-190 steel, CP-210 steel and anchorages. The results show that the anchorage cost represents about 15% to 20% of the total production cost of the prestressed beam, beings this cost higher than the concrete and formwork costs in the case of full prestressing. The relative cost of the anchorage decreases with increasing the nominal length of the deck structure.
