Television has a central position within the Brazilian communication system. In this way, it relates directly to the population so as to influence it in some way through its programming. The news programs end up being elevated like the main pieces in the formation of the opinion of the viewers, making important the analyzes regarding the construction of image. In a context where politics increasingly relies on journalistic coverage to express to voters certain thoughts, it is extremely important to understand how political facts are covered. Cases of corruption, such as "Mensalão" and “Operation Lava Jato”, have obtained and still obtain great media coverage reaching a large space within the agenda of the news programs. Therefore, the main objective of this research is to analyze the coverage of cases of corruption by Globo's Jornal Nacional. To achieve this objective, the JN programs of the last two electoral periods will be used: 2014 and 2016.

This dissertation aimed to explore how men between the ages of 18 and 27 shared and told each other online about their masculinities in a Facebook group, observing the experience reports and the qualifications of gender, sexuality and desire contained in the publications of this group. The phenomenon of digital media is a process linked to the developments of networked societies and intensified since 1997 with the commercialization of the internet and, later, with the diffusion of smartphones that brought characteristics of mobile use, personal and constant of the media. In this sense, these online imaging communities promote traditional offline reconfigurations, and it is important to realize that online and offline continually exist in ways that feed back and determine. Therefore, my research problem was to understand how the social messages of the publications of these post-1985 young people, regarding their masculinities, displace or create ruptures in vocabularies and discourses to qualify gender, sexuality and desire in relation masculinities of male-manly. The results show that the population studied has a high level of education, are familiar with the Internet, and whose imaginaries trigger fantasies of metropolitan contexts of the Brazilian middle classes, although not all of them live in these cities. In addition, homosexuality appears less marked by shame or pathology, and the manas' masculinities are understood as a source of pride. Although the belief of this youthful culture in the idolatry of media figures was visible, BIV appears as an imagined online community that provides bonds of solidarity and emotional support to its inhabitants in a multi-centered way.

This study sought to contribute to the human performance management debate in the public administration by evaluating the performance management systematics of five federal educa-tional institutions (considering nine study units). By confronting the theory, legal determina-tions and observed practice, it was possible to identify that the inefficiency of the performance management systematics results from a series of inconsistent actions in all stages of its im-plementation and include expertise lack, reproduction of performance management systems strange to culture and organizational strategy, inexistent of servant civil involvement, unpre-paredness of managers to conduct the management itself, inexistent of appraisal computeriza-tion which makes it difficult to analyze, systematize and provide information. Like this, the procedure is restricted to a pro forma reports, whose purpose is to justify the progress of the servant civil in the career. Based on the theoretical framework were proposed actions to broaden the tool's objectives; reduction of existing conflicts in the procedure conduction; im-proving processes and working conditions; continuous development of servant civil; achieve and preserve of an excellence standard in public services offer, in order to promote institu-tional and individual development by lining up the organization's strategic objectives with in-dividual objectives. This is a qualitative work and the research method consists of a Multi case Study. Data collection was done through documentary research and semi-structured in-terviews. The collected informations in the Multi case Study were analyzed from a dialogue with the theoretical framework, legal guidelines, institutional documents and the review of performance management practices with the use of content analysis.

Considering the absence of universalizing concepts capable of evaluating the transformations in the artistic field in the contemporary period, this research proposes ways of developing critical work through a theoretical and methodological framework that privileges the description of artistic productions to approximate the aesthetic fact (CANCLINI, 2016a). The general objective of this research is to decant from the problematizations of the comic book of Lourenço Mutarelli, entitled A caixa de areia: ou eu era dois em meu quintal (2006), a conception of artistic making that allows the development of an instrument of analysis for the novel by the same author, O natimorto: um musical silencioso (2009). Thus, it is intended to elaborate a methodology to present the process of constitution of Mutarelli's productions from his own artistic work, understanding how the process of problematic formalization of this artist is structured, a concept proposed by Flora Süssekind (2013) for the analysis of articulation of verbal and nonverbal elements in the composition of the literary text. From what critics identify as a supposed plastic record (SÜSSEKIND, 2013) present in the novel O natimorto, I establish research paths to think about the problematizations of limits and boundaries that destabilize the autonomy of the artistic field and the separation of the different arts. To do so, I base myself on Jacques Rancière's (2005) conception of distribution of the sensible, in order to investigate the relations between word and image within what the philosopher understands as the regimes of identification of the arts. In the contemporary period, the aesthetic regime of the arts is in operation, responsible for a disarray of the relations between word and image, between literature and other arts. In this sense, Florencia Garramuño's notion of a literature understood as an expanded literary and critical field, in which different formats and medias are intertwined, helps this research on how the literary can be configured in the contemporary Brazilian scenario.

The production of hydrogen from the steam reforming process of ethanol stands out as a process for the diversification of the world energy matrix, which aims to reduce environmental impacts and ensure energy security. Among the catalysts already evaluated for this process, those based on metals such as Ni and Co are active for the reaction, but can be deactivated by the formation of carbon on the surface and sintering of the metal particles. Among the strategies to increase the performance and stability of these catalysts, the synthesis from perovskite precursors (ABO3) makes it possible to obtain metals (B) highly dispersed in oxides (AOx). However, the compounds obtained from these structures have low surface area, which decreases the active surface of the material. To study the effects of the nature and composition of the catalysts and the increase of the specific area, Ni, Co and Ni-Co catalysts obtained from LaNixCo1-xO3 and LaNixCo1-xO3/SBA-15 perovskites were prepared and applied to the reform to the ethanol vapor. In order to define a synthesis method for the formation of perovskites on the mesoporous support SBA-15, the precursor materials were synthesized from impregnations based on the modified Pechini and amorphous citrate methods. The synthesis of perovskites on SBA-15 from impregnation based on the modified Pechini method showed less tendency to form secondary phases. The Ni catalyst obtained from the reduction of this material presented higher activity and yield for H2 production when compared to that obtained by the amorphous citrate method. From this method, materials with different proportions of perovskite on the support and mass perovskites were prepared. The increase of the perovskite ratio on the support indicated a higher formation of segregated NiO and less dispersion of the active phase. The catalytic activity and the rate of carbon formation, however, were similar among the materials, even in view of the increase in the metallic percentage. The introduction of Co into the B site of the perovskite structure leads to the reduction of the formation of secondary phases, due to the higher stability, that perovskite with the insertion of this cation in its crystalline lattice happens to present. The catalysts with Ni-Co and Co showed lower activity for the reaction, but the rate of carbon formation decreased, due to the lower Co activity in the C-C bond breakage and its greater ability to activate the water. Comparison of the performance of the supported catalysts with those synthesized from the perovskite masses showed increased catalytic activity and reduced carbon formation in the materials supported in SBA-15, due to the greater dispersion of the active phase.

This thesis analyzes the construction of the city from a study on the relationships between people living on the streets and their religious, volunteers and state interlocutors. Urban construction is thought from a situational perspective. The city is treated as the result of daily practices and seen from different positions: people living on the streets, religious, volunteers, state agents. The ethnographic research was conducted in the city of Maringá-PR between January 2015 and January 2016, during which I followed the daily life of people living on the streets and the forms of intervention carried out by Christian churches, volunteer groups and state agents. The starting point was the mapping of what life on the streets creates in political and social terms. I observed that life on the streets prompts a series of social practices, which draw attention to their disproportion in relation to the number of people living on the streets and the disagreement (RANCIÈRE, 2006) related to the ways of representing it when it is taken as reference the ways in which street life itself is understood. Thus, at least three cités or ordinances (BOLTANSKI and THEVENOT, 2006) are produced by social actors, at the same time as they provide references to justify their actions. These are religious, voluntary and state ordinances, which create administrative ways, including public policies, to intervene on street life and presuppositions for interpretations of urban order. Religious see life on the streets from the standpoint of sin and spiritual causes, voluntary as scarcity and the state as urban dirt or lack of rights. The former set out to evangelize the people who live on the streets; the latter, in the name of solidarity, to help them, and third parties, on the one hand, to remove them from the field of vision and, on the other hand, to realize their rights. The people who intervene on them become, through this intervention, public agents, militants, good Christians, organizers of the city, in other words, they produce themselves as actors, subjects able to intervene in the issues of interest that are considered as of the city. In short, they constitute themselves as political subjects. People that live on the street, on the other hand, are displaced into a position of recipients of these policies, even though they are by contrast constitutive of them. These subjects, however, elaborate a narrative about themselves that questions the external representations, in addition to creating a set of practices, knowledge and ways of interpreting their life and the contemporary world that oppose this state of things. On the one hand, they make instrumental use and re-signify the resources that the interveners bring to them. On the other, they refuse the terms of orderings assistencial, religious and state ordinances in terms of their assumptions. From this use and contestation, important misunderstandings appear that make us understand more than just ways of managing life on the streets. They also talk about urban conflict and make it possible to observe the main ordering forms of the contemporary social world, which builds the city. Specifically, I argue that life on the streets offers terms for the establishment of the following political subjects: 1) Pentecostal churches, linked to a political-religious project of a nation; 2) individuals who identify themselves as good practitioners, children of God, supporters and builders of new projects of life, as well as professional politicians, militants who think the extension of rights, or are adept at social hygiene; 3) good men who elaborate a solidarity and welcoming city representation; 4) people living on the streets are seen as objects of intervention and priority state management. The overlap between religious, voluntary and state practices about street life seems to me, therefore, a relevant sign to know the ways of building order, power and the contemporary city. Being this mechanism of urban production from the street so recurrent and relevant, nationally and internationally, I suggest in this thesis that it is, sociologically, treated as a structuring mechanism of urban life.

Studying the relationship between what is done and what is said has occurred in several sciences, including Behavior Analysis. The present study employed do-say sequence and examined, experimentally, the effect of the audience on the phenomenon of correspondence in self-report in adults. The first stage of this thesis consisted in the elaboration, production and testing of a 3D virtual game with the function of an instrument for data collection. The next step was data collection and analysis. Ten male college students were submitted to the game. The experimental task consisted in collecting red and green objects in the game scenario and reporting "yes/no", if they collected the reds that were prohibited. Audiences were established through the characters of the game, one of which indicated only punishment, another only reinforcement and another signalized, in an ambiguous way, both punishment and reinforcement. After the game, the participants evaluated, through a questionnaire, the game and the characters, with the objective to check if they responded adequately to the programmed characterization for the audiences. The results indicated a higher frequency of distorted reports for the audiences that indicated punishment or ambiguity between punishment and reinforcement. This indicates that the audience had an effect on the accuracy of verbal reports of adults in a virtual environment.

Leishmaniasis is an infection caused by Leishmania gender protozoa. The treatment of the disease is generally problematic, as the drugs used on clinical practice are toxic. One of the paths in the search for new therapeutic targets is the study of endophytic microorganisms-produced substances. In this study, the Total Lyophilized Extract (TLE) of the endophytic Paenibacillus polymyxa RNC-D was used, which was isolated from the Cerrado of São Carlos, Brazil. The TLE was assessed in terms of citotoxicity, ON production and citokynes production on BALB/3T3 fibroblasts, J774A.1 macrophages, RAW 264.7 macrophages, as well as directly on promastigote and amastigote stages of Leishmania (L) amazonensis. Our results have shown that the mortality rate of 50% (EC50) of fibroblasts (BALB/3T3) was of 1,171 mg/mL and 0,956 mg/mL after 48 and 72 hours, respectively. For macrophages (J774A.1) the mortality rate of 50% took place on doses of 0,994 mg/mL and 0,945 mg/mL after 48 and 72 hours, respectively. Regarding cellular death, at the period of 24 hours, the extract induced apoptosis and necrosis from the concentration of 5mg/mL in fibroblast (BALB/3T3) and from ≈1 mg/mL in macrophage (J774A.1). The threatment with ≈1 mg/mL concentration of the ETL induced TNF-α, IFN-γ and IL-10 cytokine production at the 24 hours period. The IL-10 had its production detected up to the 48 hours period, whereas the IL-12 was detected only at this period. For the toxicity essay on L. amazonensis promastigotes, the values of EC50 obtained at the 24 and 48 hours period were of 0,624 mg/mL and 0,547 mg/mL, respectively. Regarding promastigotes death percentage, our result have shown that the 0,5 mg/mL concentration induced death of 31% at the 24 hours period and 35% at 48 hours. As for the concentration of 1mg/mL of the extract, the death percentage was of 59% and 62% at the periods of 24 and 48 hours, respectively. For the parasitary load essay, it was observed a percentage of 25% of infected cells with na average of 3 amastigotes/cell for the groups treated with 0,1; 0,5 and 1 mg/mL of the TLE at both periods. Regarding cytokine production on RAW 264.7 macrophage that were infected/treated with the extract, a significant increase of TNF-α was observed at both periods for all tested concentrations. Concerning IFN-γ cytokine, its significant production was only observed at the 48 hours period in the 1mg/mL concentration, whereas the IL-12 production was only significant in the 0,5 mg/mL at the same period. A significant decrease of IL-4 was observed in all treated groups with the TLE at the 24 hours period. The significant ON production by RAW 264.7 macrophages was observed in the groups treated with 0.5 mg/mL and 1 mg/mL of the extract on both periods of 48 and 72 hours. Due to its modulatory action of the immunological activity, it is suggested that the TLE of P. Polymyxa RNC-D is a promising target for the development of new immunotherapeutical drugs for the treatment of several diseases, including, but not limited to, leishmaniasis.

Zinc phosphide Zn3P2 nanowires with excellent crystalline quality were grown using the Vapor-Liquid-Solid (VLS) method with gold nanoparticles as catalysts. Single nanowire based devices were fabricated with ohmic nickel contacts. Thermally activated and variable range hopping mechanisms were simultaneously identified from temperature dependent transport measurements, with the later being dominant. Energy levels at 197 meV , 47 meV and 15meV associated to Zn vacancies and interstitial P atoms were identified. Hopping radius were found to be 58 nm for 300 K. These results show how the presence of some degree of disorder drastically affects the transport of current through the nanowire. Photocurrent measurements revealed the material potential as light sensors. Current gains as high as 400% and 660% were measured for white light and 660 nm laser, respectively.

This thesis is based on his historical and cultural approach, wich recognizes the historicity of the human being, values the transmissin of socially acquiered knowledge, assumes that constitutions of the subject happens from relations with the environmment and also emphasizes that human language is conceived in social life, referring to the ideia that is her, by her and with her that the individual will be constituted. The theoretical dialogues with legal issues, with public policies and social movements that have permeated the education of the deaf person was constituted from his own narratives and thus to look at: his educational trajectory; challenges to their educacional background; the marks left by their linguistic singularity; and the school in the process of social interaction and development of these people and the emergence of deaf communit and deaf movements in Pernambuco. In this way, the objectives are: a) to outline the profile of constitution of the deaf person in the state of Pernambuco, through educational aspects, stories and memories narrated by leades of deaf movements; b) to know how in that state the deaf collective that has dominion and makes use of sign language has been formed and c) to identify how aspects of social movements were fomented and what is the role of education in this history. It is a qualitative research, based on Oral History referred to, Meihhy by Thompson, Meihy and Montenegro. The Oral History of Life reconizes and values people as subjects of their own history. Eleven deaf leaders were selected, all fluent in Pounds, residing in Pernambuco (state of Pernambuco). The results show that human development is not restricted only the biological factor, but encompasses the historical, the human and the social factor, and encompasses the historical, the human and the social. The cultural constitutucion of the interviewees was crossed by the other (deaf and listener), who, in the process of interaction, made them construct concepts and meanings that reaffirmed their reality over time. From the reports, the analyzes were organized in the follow axes: family environment, language, educacional trajectory and involvement in social movements. The family participed in social interactions without sharing sign language, except in cases of deaf parents, and dealt better with their menbers was deaf. Sign language was acquired in adolescence by the majorit, in the encounter with another deaf, in its educacional trajectory, that was marked by evasions, repetition, failure. However, the school in which Libras was present (common school or school of the deaf) was signified as na interaction loci, a place of coexistence between peers, impelling other meetings in other spaces, thus contributing to the formation of the deaf movements. The associations, militants and social participations were present in all the narratives. It is believed that it is important to carry out more research that uses the History of Life method, allowing a moment of “listening” to is collaborators, to deepen the knowledge about the education of the deaf in Brazil.

La recherche a mis son attention dans les éventuelles mutations ou permanences dans les formes de promotion de la lecture accomplis au Brésil. Pour ce faire, nous avons réalisé une analyse discursive de représentations de pratiques de lecture dans textes variés, à savoir, documents officiels réglementaires de la question de la lecture au Brésil, manuels d’enseignement, campagnes, proprement dit, d’encouragement à la lecture, textes diffusés dans la presse que concernent à ce sujet, entre autres matérielles que touchent direct ou indirectement au thème de la promotion de la lecture au Brésil, en provenance desquels nous avons pu voir comment cette pratique a été conçue et discursivisée, et, de cette façon, promu dans distinctes moments de son histoire. En raison de notre intérêt en réaliser une étude historique et discursive, les deux théories dans lesquelles nous nous appuyons sont l’Analyse du Discours d’orientation française et l’Histoire Culturelle de la Lecture, champs où s’essaye de comprendre, chacun à sa façon, « comment on lit » et « pourquoi on lit comment on lit ». Les continuités et discontinuités dans les raisons et formes d’encourager la lecture ont été pris des actions d’éradication de l’analphabétisme, de la préoccupation avec la production et distribution du livre, des recommandations données aux parents et aux professeurs sur comment motiver la lecture dans la sphère familiale et le milieu scolaire et aussi des discours diffusés en vidéos de court duration disponibles dans le site du YouTube, qui ont l’objectif de promouvoir la lecture. Nous avons pu vérifier que le discours de promotion de la lecture a toujours existé au Brésil, puisqu’a toujours existé aussi un imaginaire sur un déficit de cette pratique dans le pays. Cependant, cet encouragement ne s’est pas passé toujours de la même façon, ni avec le même impact, non plus avec les mêmes agents. Malgré l’apparent paradoxe, ce que nous avons constaté, quand même, c’est que, de façon générale, son encouragement a présupposé affirmer son importance, travailler par son expansion et nourrir sa rareté.

Exercise intolerance is a multifactorial hallmark of both heart failure (HF) and chronic obstructive pulmonary disease (COPD). Following submaximal exercise, oxygen uptake (V̇O2) recovery kinetics seems to be limited by O2 delivery to exercising muscles. Interventions that target increasing skeletal muscle O2 delivery and/or reducing O2 demand might increase exercise tolerance and speed metabolic responses during exercise recovery. Therefore, two studies were performed and aimed to investigate the influence of co-existing HF and COPD on V̇O2, heart rate and cardiac output recovery kinetics after constant-load exercise test (CLET) and to explore the effects of non-invasive positive pressure ventilation (NIPPV) on exercise recovery kinetics in patients with co-existing HF and COPD. The first one, titled “Central haemodynamics and oxygen uptake recovery kinetics during high and moderate intensity exercise: the negative impact of co-existing heart failure and chronic obstructive pulmonary disease”, included 9 HF-COPD and 10 HF patients who underwent two CLET at moderate and high loads. The results suggest that the combination of HF and COPD may further impair exercise recovery kinetics, compared to HF alone. The second study, entitled “Noninvasive ventilation accelerates oxygen uptake recovery kinetics in patients with combined HF and COPD”, included the same patients who were submitted to a high-CLET with NIPPV. The results showed that NIPPV accelerated the V̇O2 recovery kinetics to a greater extent in patients with co-existing HF and COPD compared to HF alone. Hence, the recovery profile assessment after submaximal CLET might be helpful to comprehend the pathophysiologic characteristics that contribute to symptoms, such as dyspnea and fatigue, and exercise intolerance. NIPPV should be considered when the objective is to apply high-intensity interval exercise training as an adjunct intervention during cardiopulmonary rehabilitation program.

This research studies the prestress effect on structures of flat plate and beams of concrete. The work consisted of coupling a computational subroutine in the already existing platform, the CALCO. Currently the system allows the analysis, calculation of stresses and displacements, of concrete floors through the equivalent grid and was developed by (CASS, 2015). Initially a module was designed that allows the use of curved pretension cables with predefined geometry. To facilitate the introduction of the pre-tensioning efforts the cables can only be applied to the bars of the grid, and the user can create pretension bands. Then the module in question will transform the pretension action into equivalent nodal stresses. In this way, all the isostatic and hyperstatic stresses of the structure can be calculated. Examples are made and compared with existing programs.

Self-compacting concrete has specific characteristics that differ from conventional concrete. Its self- compacting capability, ease of pumping, excellent homogeneity and resistance to segregation are highlighted, being these characteristics obtained by its composition. On the other hand, the recycling of waste from civil construction has aroused great interest and consolidated as an important practice for the sustainability of the construction sector, by reducing the environmental impact generated. Among the purposes that have generated great interest is the use of construction waste as a recycled aggregate. In this way, the present study tried to evaluate the influence of the substitution of the natural aggregates for recycled (big and small). The dosage of self-compacting concrete was performed according to the method proposed by Alencar and Helene. From the reference trace (AN REF), three traces were produced with 30%, 50% and 100% recycled aggregate replacement (AGR 30, AGR 50 and AGR 100) and 2 traces with substitution contents of the recycled kid's aggregate of 30% and 50% (AMR 30 and AMR 50). Tests were carried out in the fresh state of the mixture for determination of scattering and run-time, visual stability index, passing ability by ring method J, passing through L method, viscosity by funnel V method and resistance to segregation by the segregation column method, to verify the self-density of the concretes. In the hardened state, tests were performed to determine the resistance to simple compression, tensile strength by diametrical compression, modulus of elasticity, absorption of water by immersion, voids index and specific mass. The concretes produced presented satisfactory performance in the fresh state, being considered self - supporting. As for the mechanical behavior, the concretes presented resistance to compression similar or even superior to the reference concrete. The modulus of elasticity decreased as the substitution content of the recycled aggregates increased. The results of water absorption by immersion and voids index increased as the substitution content of the recycled aggregates increased. Through the present study, it can be seen that the incorporation of recycled aggregates (large and small) from construction waste is an alternative for the production of self-supporting concrete.

Researching biodiversity and understanding environmental responses to anthropic modifications considering multiple system scales and particularities have become even more urgent. A way of understanding community’s setting processes and its biological responses consists of using diversity measures which cover different aspects about the composition, funcionality and the evolutive history of the environment. Considering that the changes caused by urbanization reflect in fish communities, we hypothesize that urbanization functions as an environmental filter, selecting species and influencing the diversity of ecosystems, therefore, the aim of this study was to compare through taxonomic diversity and functional indexes, stream fish communities which live either in rural and urban environments along the Upper Paraná River basin, located in the Southeast region of Brazil. In order to accomplish that, it was written two chapters about 48 different stream’s icthyofauna in the Atlantic Forest region: out of the total, 30 and 18 streams are located in rural and urbanized environments, respectively. In CHAPTER I, it was evaluated the taxonomical diversity among fish communities by measuring total specie richness (S), average richness (S ̅), estimated richness (S*), the Shannon-Wiener’s indexes of effective species (e^H') as well Simpson’s dominance (1/D). We observed that the taxonomical indexes were higher to the rural environments, indicating that, in terms of taxonomic, the rural environment diversity is higher when compared to the urban zones. In addition, in CHAPTER II, functional diversity standards of the communities were compared among rural and urban environments by analyzing food and locomotion morphological atributes of fishes. This index were adapted to functional quantitative indexes as richness (Fric), equability (Feve), dispersion (Fdis), divergency (Fdiv), specialization (Fspe) and originality (Fori). Rural environment presented higher functional dispersion than urban zones, whereas, streams which are inserted into urbanized environments showed a higher specialization and functional originality. Thus, it is evident that urban environments present a more homogeneity in their function distribution along the system, altough these functions are more original and unique. As final results we have gotten differences between taxonomical and functional diversity standards which happened due to the anthropic modifications into the system; these modifications, therefore, can work as important environmental filters within the organization of stream’s fish communities.

This research is positioned between two different lines of thought: one that denunciates current forms of operationalization of the social matter as forms of control, and the other that presents Politics related to certain forms of surpassing poverty, amongst them Solidarity Economy in general and, more specifically, Community Development Banks. Here are some thoughts about women’s place in public life as ways for treating poverty that transform the economy and also contribute to the construction of women as subjects of rights, capable of exposing their dilemmas and vindicating their rights. This work aims to explore the impacts of a public policy for surpassing poverty based in solidarity economic principles in the daily life of its beneficiary parties, for their emergence as political subjects. Therefore, with a foundation in the methodology of the research-action, I present my experience with the activities developed in a Community Development Bank named Banco Comunitário de Desenvolvimento Nascente, located in São Carlos-SP-Brazil, and the experience I shared with the working women of this enterprise, the local development agents.

The aim of this study is to make a framework of a Workload Control (WLC) approach in commercial software for discrete event simulation. This study is justified because although have a lot of researches on this approach, there are no studies or tutorials that demonstrate how to model and simulate which types of commercial’s software. This study uses the modeling and simulation method. The main result is a description of the construction of the framework showing in detail how to simulate the WLC approach in a commercial software for discrete event simulation, in which a first moment of the logic of the problem is developed in MATLAB’s system, where it is based on a shop floor model researching of Land (2006), the conceptual algorithm of the WLC is developed to verify the consistency of the invented part before making a conversion to the simulation software. Finally, the WLC logic is developed and are constructed and simulated on a simulation scenarios from of literature. It is also possible to build different scenarios that operate based on WLC policies in search of leaner outcomes such as the needs of the modeled factory floor, contributing to a real situation. This work in the business and academic environment, which facilitates the replication and application of framework in other environments, facilitating the progress of the project, evaluation for the assembly of the base model, allowing the direct focus on the comparisons and adaptations of the environment of managers and / or researchers.

In this thesis we studied the transmission of entangled states in unmodulated spin chains using a slight modification in the XY isotropic model (XX model) that describes a one-dimensional spin-1/2 chain. We have shown that it is possible to transmit bipartite entangled states from a sender to a receiver with high fidelity from one end of the chain to the other. This transmission occurs without the need for external fields or modulation of the coupling constants between the qubits, which simplifies its pratical implementation. We verified, through numerical analysis, that the modification in the one-dimensional model works for any size of the chain. We also verified that the proposed model is robust for small imperfections in the coupling constants, low magnetic field noise and residual interection between spins in the z direction. At last, we analyzed whether the proposed model can also be used as a transmitter of single qubit states and we discussed these results within the context of the quantum information theory.

In Brazil, the urbanistic instrument Urban Partnership Operation was regulated by the City Statute in 2001. With public and private capital, this instrument seeks implement a series of urban interventions in specific area of the city, aiming structural urban transformations, social improvements and ambiental valuation of this region. The city of São Paulo was pioneer in use of this instrument, it was included in Master Plans since 1985, with a series of adaptations from its beginning to the present day. The objective of this dissertation is analyze the housing issue involved in the application of this instrument, specifically in Água Espraiada, implemented in 2001 in São Paulo, focusing on the production of social housing and social and economical care to the population directly affected by the operation. Through a careful analysis of documents, data and informations provided by the city of São Paulo, as well as bibliographical and documentary research, was possible to observe contradictions in the application of the instrument in the case studied. Despite the social appeal contained in the discourse of Urban Partnership Operation, the economic purpose of its application was evident, once priority was given to real estate capital, to detriment of a more inclusive urban policy. In conclusion, even with the implementation of the new Strategic Master Plan of 2014, tha contradictions of capitalist urbanization are present in the county, evidencing the power of private capital in the conduct of urban development of the city. It is also pointed limits in the application of the operations, so that they are implanted through different dynamics from those initially prevalent and move away from the exclusionary and concentrative nature that has chacacterized it.

This dissertation from a research conducted at a Women's' Police station of a city inside the state of São Paulo, where it was looked for to understand the police attendance and the agents' procedure in the police inquiry for when the target of the violence is an adult woman and for when he/she is a child or adolescent, starting from the daily policeman's observation, of interviews with agents and of the analysis of inquiries on sexual violence. During the field work it was observed that the women's great majority assisted at the police station manifested, after the police report, the will of not continuing with the case, same and, above all, in bodily harm occurrences – crime that doesn't depend on the criminal representation to establish the inquiry. In lathe of that fact and, along the observations, it was noticed that a lot of women that manifested a juridical and personal choice different from the one that the police station is capable to offer, they were disqualified of "victim's" category by the agents. It was inferred that the logic of the penal protection backed by the Maria da Penha Law guides the police conduct addressed the assisted people, be adult women or children and adolescents, minimizing the orientation on police procedure and constitutional rights to the adult clientele. Still in field work it was observed that most of the police report and inquiries on crimes against the sexual dignity targeted the violence against children and adolescents. It was also observed a lack of adaptation and preparation in the police procedure for the treatment of sexual crimes against children and adolescents.
