To organizations can contribute to sustainability, they should modify its productive processes in global sense. Therefore, should internalize, besides the economic and structural factors, the natural environment and social questions, that is, the principles of social and environmental sustainability. This tendency includes the Brazilian sugar cane ethanol, which has significant impact in the environmental, socials and economic country questions. As shown in some reports about business sustainability and corporative disclosed by the mills with distilleries (ethanol and sugar), part of this sector has utilized instruments whit tendency to the sustainability process, such as certifications SGA, ISO 14.001, Cleaner Production, Lifecycle Review among others. In this scenario, important to Brazil, this study had as objective review the practices of business management of mills whit distilleries attached sugar cane processors in the administrative region of São José do Rio Preto, state of São Paulo, Brazil, given the principles of social and environmental sustainability. For this, it was applied the qualitative methodology, exploratory and descriptive, primary and secondary research by through questionnaires. The results and analyses were performed to correlate the principles, the dimensions and indicators of social and environmental sustainability versus the mills practices, resulting in identification of the trend level of social and environmental sustainability of the mills. It is concluded that more than 40% of the practices of the mills are not aligned, others are aligning and other are aligned whit the principles of social and environmental sustainability. Therefore, almost half of the practices used in the mills are not, actually, whit the tendency to social and environmental sustainability. It is suggested that the mills decide internalize the principles of social and environmental sustainability in its upstream processes downstream of the sugarcane ethanol industry early in the planning conscious design, seen that its today practices, certainly, will have consequences in the future; and that this practices are continuous and favorable to the principles of social and environmental sustainability, therefore, to the life quality of the population and the own mills, in its corporate business management.

Endotracheal suction (ES) in mechanically ventilated patients is required for maintaining a patent airway. Open circuit endotracheal suction (OCES) may cause greater damage to respiratory mechanics and gas exchange. There is little evidence about the impact of the use of oxygen concentrations below 100% and the expiratory pressure-zero end expiratory pressure (PEEP-ZEEP) technique at increasing oxygenation and maintaining adequate ventilation during the OCES. In addition studies were not found concerning need or not of hyperoxygenation associated with the PEEP- ZEEP and the effectiveness of isolated hyperoxygenation with oxygen concentration 20% above the baseline, thus justifying the studies of this thesis. Study I aimed to evaluate whether the 20% oxygen concentration of inspired oxygen fraction (FiO2) above the baseline avoids hypoxemia compared the offer to 100% and determine the impact of OCES on pulmonary ventilation in critical patients on mechanical ventilatory support. This randomized crossover study involved 68 patients in an adult intensive care unit (ICU), intubated, mechanically ventilated and placed in the two intervention sequences: Hyperoxygenation using 20% above FiO2 (FiO2 20%) and Hyperoxygenation using 100% FiO2(FiO2 100%). Hyperoxygenation was applied 1 min before each of the 5 ES and 1 min after OCES. The studied variables were measured pre, immediately after and 1min, 2 min and 30 min after OCES. There was a significant intra-group increase in immediate post FiO2 20% and 100% on peripheral oxygen saturation (SpO2), carbon dioxide (CO 2) exhaled at the end of expiration (ETCO2), partial pressure of CO2 in the mixed expired air (PeCO2 ), heart rate (HR), mean arterial pressure (MAP), and in the tidal volume of CO2 (VtCO2) only for the FiO2 20%. Intergroup in the immediate post in VtCO 2, ETCO2 and SpO 2 restoring the pre intervention values 30 min after measurement. It was concluded that an oxygen concentration of 20% above baseline FiO2 for patients with need of prior offer  60% effectively avoided hypoxemia and volumetric capnography analysis confirms that changes in pulmonary ventilation in OCES in critical patients are transient and reversible within 30 min. These findings also support the implementation of Study II which aimed to verify behavior of peripheral oxygen saturation (SpO2) and exhaled end- expiratory CO2 (ETCO2), for the OCES procedure, using PEEP-ZEEP baseline FiO2 versus PEEP-ZEEP hyperoxygenation using 20% above FiO 2. This randomized crossover study involved 38 patients in an ICU, intubated, mechanically ventilated and placed in the two intervention sequences: PEEP-ZEEP with baseline FiO2 (PEEP-ZEEP FiO2 baseline) and PEEP-ZEEP with 20% above FiO2 (PEEP-ZEEP hyperoxygenation). Hyperoxygenation was applied 1 min before each of the 5 procedures and 1 min after OCES. PEEP-ZEEP with 3 series before each of the 5 ES. The studied variables were measured pre, immediately after and one, two and 30 min after OCES. There was significant increase in SpO2 on PEEP-ZEEP hyperoxygenation, with maintenance of adequate levels on PEEP-ZEEP FiO2 baseline no change in ETCO2 in both interventions. Significant difference was found in intergroup SpO2 post 1 min of hyperoxygenation, immediate post, post 1and 2 min of OCES. Significant difference was found in intergroup SpO2 post 1 min of hyperoxygenation, immediate post, post 1 and 2 min of OCES. It was concluded that the PEEP-ZEEP technique, when well indicated, associated or not to hyperoxygenation is effective to avoided the fall of SpO2 and maintain levels of ETCO2, minimizing the impairment in the ventilation caused by OCES.

The corrosion resistance and mechanical properties of hardness and toughness of a welded joint multipass duplex stainless steel have been evaluated under the condition with post-weld heat treatment and as-welded. The microstructure along the weld varied as a function of the thermal cycles of the welding process. The heat affected zone (HAZ) showed a higher amount of ferrite and larger grain size. The weld metal (WM) showed more refined microstructure, given by the metal composition of addition used. The parent metal (PM) has not microstructural changes to be far to the fusion zone. The results obtained in electrochemical tests, immersion and mechanical showed that the HAZ presented the pitting potential less noble and higher degree of sensitization in relation to WM and PM. The higher hardness and lower toughness were observed in WM due to the refined microstructure. It was also observed that the post-weld heat treatment reduced the hardness and increased toughness over the joint, reducing the difference of values of these mechanical properties between different regions of the weld. In the corrosion resistance, the effect of the heat treatment was observed in the reduction of the degree of sensitization of the HAZ, it is not significant in pitting potential. The highest rate of corrosion in the welded joint was obtained in the condition as-welded, and observed an attack in the HAZ region. Considering the degree of sensitization and the rate of corrosion of the HAZ, we investigated the presence of precipitates in the region by means of scanning electron microscopy (SEM) and transmission (TEM) with a qualitative chemical analysis and semi-quantitative for energy dispersive X - ray (EDS). The results showed the presence of chi phase, sigma and secondary austenite responsible for the sensitization of the joint as-welded.

In this dissertation we present a result of classi cation of isometric hypersurfaces between Lorentz-Minkowski spaces due to L. K. Graves [5], which generalizes a classic theorem of Hartman and Nirenberg [7], where hypersurfaces were classi ed among Euclidean spaces. The technique we use in this classi cation of hypersurfaces is to rst study the completeness of the relative nullity foliation, and split the demonstration in two cases depending of the foliation be degenerate or not degenerate.

The tactical management of cash flow is critical in financial management of a company or organization. Several mathematical models for planning cash flow have been proposed in recent decades. Most of the models are deterministic and initially treated as an extension of the economic order quantity. This thesis addresses the cash management problem from the perspective of optimization models present in the Operations Research literature. The aim is to study, develop and apply formulations based on mathematical programming and network flows, considering uncertainties in parameters, to support the decisions involved in managing the cash flow. A case study was developed in a typical company of the stationery sector to analyze the suitability and potential of the proposed approaches for companies of this sector. For that, this thesis implement robust optimization and stochastic programming to address the parameters uncertainties in the problem of maximizing the available financial resources at the end of a multi-period and finite planning horizon of the company's cash flow. The proposed approaches are based on a deterministic model which uses a network flow to maximize the cash flow return at the end of the period. For the treatment of uncertainties in the parameters that define the flow of financial resources in time are used the robust optimization approach of worst case interval and the stochastic programming approach risk neutral, minimax with regret and conditional value-at-risk. There were no other studies in the literature following this line of research. As shown in this thesis the proposed approaches can generated promising results for the management of cash flow in companies of the stationery sector and others, with significant contributions in financial decision-making department, particularly for the treatment of uncertainties in the parameters of the cash flow.

The actions of National Agreement for the Literacy at the Right Age, known as PNAIC, constitutes the most recent educational public policy proposal that intends to promote literacy for all children up to 8 years old. The proposal includes the teachers' training among these actions which brings a contribution to teachers' performance. As the national agreement settles in along with a qualitative research, this work aims to bring a case study to meet three state elementary education teachers' perceptions. These teachers work in a country side city in the state of Sao Paulo, each one works in a different grade – first grade, second grade and third grade of elementary school. We characterized the course according to the written language offered by these three teachers in 2013 under the structural context. It also included the possible contributions for their professional development. We performed the current PNAIC legislation study along with thesis and dissertation electronic research including three PNAIC universities: UNICAMP (Universidade de Campinas), UNESP (Universidade Esadual Paulista), and UFSCar (Universidade Federal de Sao Carlos), all linked to previous public policies before PNAIC. We also interviewed teachers and their PNAIC tutors, and we analyzed the School Management Plan; we listed the materials offered to teachers (classroom books), and for their tasks with students (board games and children's books). We especially relied on works by the following professionals: Ana Carolina Marsiglia, Bernadete Gatti, Claudio Félix dos Santos, Dermeval Saviani, Elaine Eliane P. de Souza, Lígia Marcia Martins, Magda Soares, Maria do Rosário Longo Mortatti, Maria Iolanda Monteiro, Newton Duarte, Romy Salomão e Sirley Tedesco. The results are based on teachers' understanding about the need of a public policy for teacher's training and fringe benefits such as scholarships and materials distribution not only for teachers' training but also children's books and literacy games. Nevertheless, there are intriguing facts that deserve special attention to be reviewed upon the agreement implementation: the steps that the proposals go through before reaching the students, such steps embodied by the universities coordination that train the teachers, study tutors, faculty formation and the professors, just to mention a few. It is clear that the several instances that the teacher's education has passed and all the interests involved are prone to distort the faculty proposal thus endowing the existing gaps in the formation books by leaving the original proposal behind. The strength of the teacher's formation offered by the PNAIC proposal became unfruitful to grant teachers' professional development since it has not even close to ease the harsh work conditions and the reality of the school community.

The aim of the present work was the study of the viability of a manufacturing route of parts with the Cu-based Shape Memory Alloy (SMA) Cu- 11,3Al-3,2Ni-3Mn-0,5Zr through gas atomization followed by Selective Laser Melting (SLM) consolidation. The alloy was prepared from high purity elements in an induction furnace with a concentrate argon flow shield above the molten metal. The atomization was carried out using an induction furnace for melting and argon as atomizer gas. The atomized powder was sieved in 32-106 μm range particles sizes and consolidated by SLM 250 HL device settled at the Leibniz Institute for Solid State and Materials Research, Dresden, Germany. In the consolidation step the best combination of power (P in Watts) and velocity (V in mm/s) were selected through the visual aspect criteria. In the following step the hatching track percentage (S) guided by relative density criteria was included. The atomized powder and the consolidated samples were characterized by optical and electron microscopy, X-ray diffraction and differential scanning calorimetry. The composition and the powder morphology were suitable for the SLM processing. The parameters optimization point out that the best combinations were P310v740S40 and P310v740S50, their relative density were around 97 %. The β’ “zig-zag” martensite phase, the SMA effect cause, was prevailing in the consolidated samples microstructure, still, the microstructure although was not-uniform it was relatively grain refined, pointing out the effect of Zr addition. The consolidated samples transformation temperatures were As=172-174C, Af=194-197C, Ms=156-160C, Mf=132- 138C. The results point to a strong indicative of the viability of a manufacturing route of parts with Cu-based SMA through gas atomization followed by SLM consolidation.

Le texte présentement écrit cherche, d'un côté, à faire surface au critère ontologique au fond de chaque description entreprendre par Merleau-Ponty. Dans ce sens, la temporalité révèle la racine autant des descriptions du corps et de la perception que du langage. En approfondissant l'analyse de la structure temporelle et en même temps en nourrissant de quelques commentaires de Moura, on se demande sur ce qu'incite le temps à être toujours une “puissance de passer outre” de chaque moment présent, sur ce que fait le temps un mouvement de perpétue s'écouler. Tel investigation se tourne vers les considérations sur le désir, en rapprochant, ainsi de la thèse de Saint-Aubert et des commentaires de Ramos. D'autre côté, il cherche de montrer des ajustes conceptuels que Merleau-Ponty a entrepris en visant le dépassement de certes préjugés de la première période de sa pensée. Dans cette perspective, il faut souligner que l'auteur se détache de la base phénoménologique du « a priori de la corrélation » et développe une ontologie qui contemple aussi la Nature. Par cela, le critère ontologique de la première hase de sa pensée (la temporalité) soufre quelques transformations. L'apport théorique offert par la linguistique de Saussure permet à Merleau-Ponty s'arrêter de concevoir les instants temporelles comme des positivités (le Cogito tacite), en y montrant enfin comme des différentiations (des différences sans termes).

The restoration should involve the return of vegetation cover and ecological processes. This study aims to assess whether the restoration of diversity also promoted the recovery of the ecological functionality of an area located in the Atlantic Forest, in Rio de Janeiro. During the study, a set of ecological functionality of indicators based on community diversity, its structure and its context in the landscape were analized. The most efficient indicators for evaluation of the areas were the structure (density, height and basal area), followed by diversity and evenness (H 'and J). Between the 5th and 20th month, there was a significant reduction of diversity, further for families than for the species. However, indicators of ecological functions did not change between the ages despite the reduction in diversity, showing that there was redundancy of functions between different species. The results suggest the deployment of fewer species maintaining the proportion of the functional diversity of species can optimize the actions of forest restoration for promoting the reduction of mortality, therefore generating greater increase in community structure. The regenerating analysis showed the importance of faunal interactions in forest restoration activities, since 77% of regenerating species found in the area have zoochorous dispersion syndrome.

The use of metal oxide nanoparticles in nanocomposite has provided new and interesting properties and is one of the most promising areas in composites. Compatibility between these nanoparticles and polymer matrix is the most critical fator on development of these materials. In this context, this thesis project has focused on study of synthesis and functionalization of magnetite nanoparticles (Fe3O4) aiming its incorporation into bisphenol A based diglycidyl ether based to produce nanocomposites with very high compatibility between dispersed and matrix phases. Synthesis and functionalization of nanoparticles were performed in a single step by thermodecomposition of iron (III) acetylacetonate in poly (1,4- butanediol) with molar weight 1000, which served both as a solvent for the reaction as a source of molecules for surface functionalization of the nanoparticles. Nanoparticles with an average size of 8,4 nm and with high volume fraction of organic layer were obtained and the synthesis was highly reproducible. The produced nanocomposite exhibited high homogeneity of nanoparticles dispersion and the absence of large agglomerates. The interaction between the nanoparticles and matrix occurred through the chemical reaction between the functional groups of the organic layer and the DGEBA, as was expected, and through intercalation of DGEBA molecules between the molecules from the organic layer, thereby creating a new interphase with unique properties. Due to the high volume fraction of this new phase, the density and modulus of elasticity exhibited behavior that could not be explained by traditional methods. A new approach was used to develop a model that considered this third phase and set more consistently to the experimental data obtained, and showing the domain of this new interphase on the nanocomposite`s properties.

This research aims to understand the dominant circulating senses and, therefore, appear as a true effect on being a Portuguese language teacher in Brazil. Understanding that the senses are linked to the work of ideology and language policies, which as part of the subjectivation forms (in an unconscious process) of teachers, try to hold individuals responsible for their profession to be (dis)articulator of failure of language teaching. The senses of Portuguese as a national language works to produce the effect of the difficulties of Portuguese and here we will present and analyze how these constructions were possible throughout the history of the schooling of our foreign national language. We understand that the issues related to language teaching are not linguistic issues, but political is that we present our work so that we understand that to say about the Portuguese teacher as a teacher who is always exposed to lack in the schooling processes is the condition of never be allowed to be a producer of his own linguistic knowledge. Teachers of Portuguese not authorized to produce their knowledge are discursively constituted by the lack, a kind of lack of capacity to produce this knowledge by the legal demand of only reproducing the strategies of education legitimized by the public policies on literacy and the teaching of the language understanding that this is a way of dismantling them, thus disarticulating the teaching of language in public schools.

Supported by the Classic Laugh and Humor Theories as background, according the approach of the anthropology of performance and the ethnographic work carried out in a comedy club in São Paulo city, this work aims to understand the construction of the comic in stand-up comedy performance through three areas of analysis, namely: 1) local relations, text and scenario; 2) the oral narrative as bases of stand-up comedy; 3) the public as counterpart. Seeking to bring out the humorous experience, seated in the performer-space-audience triad, this study brings, in ethnographic narrative, elements that influence and build the stand-up comedy into its scenic context, such as the environment, interactions of the audience and extra scenic components, which act as an emergency supports of the comic genre. It also discusses about the comedian training, aesthetic limitation, the textual production, live scenes and other elements, in order to the compression of the laughter and the stand-up performance. In turn, the audience laughter, as a comedian purpose and expectation of the public, emerges from the negotiations between the present, whose narratives outweigh the telling of jokes and laughter comes over as part of the scene than simply as a result of the jokes.

In Brazil, the Official authorities send children and teenagers who need special legal protection to an Institutional Shelter and/or a Foster Care, which priorities are: to promote a health development, social and familiar reinstatement, and/or inclusion in the host family, as much as for detachment of family or institution. However, some cases of sheltering extend the time, which brings psychosocial consequences in development process of the foster children, such as: feeling of unpreparedness, fear, sadness, which happens mainly after detachment. Therefore, this study aims to analyze the effects of a training involving skills for life, specifically skills of assertive communication, applied to teenagers with intellectual disability that live in Institutional Shelter situation, which focus on improve the quality of their social living. This is a qualitative and quantitative research. In order to proceed with data collection we applied two semi-structured questionnaires to technical team of the institution. One of them aimed to characterize the participants and the other one aimed to observe the understanding of the technical team about communication skills deficit of teenagers participants of this study. After that, we applied a board game of social interaction to teenagers with purpose of identify deficit regards to these skills and the benefits of the board game. The data collect were achieved through a set of conversation where the training were applied. The analyses were based on “Content Analysis”. It has participated of this study four teenagers with Intellectual Disability that live in an Institutional Shelter situation.The results pointed out that the training has improved some verbal, non-verbal and also paralinguistic components, which were in deficit regards to communication's repertoire of the participants. Furthermore, it has pointed out that other components were developed, even they were not part of the research: start, maintain and stop a conversation. However, some participants have not changed regards to specific components of assertive communication. The results also pointed out the need of application of others studies, as much as elaboration of other strategies of intervention.

Public policies have increasingly recognized tourism as a means of reducing social inequalities, fostered the development of the activity at different scales. Despite the expectations created by these policies, tourism has not yet consolidated effective recognition among different sectors of society in relation to its role in local development agenda. This study assumes that the attenuation of social inequalities should conform an elementary goal of tourism development and it is based on the question of what has been the contribution of tourism public policies to achieve this role. Thus, the study covers the municipalities that received the title of tourist municipalities between the 1990s and 2010. It employs the method of difference in differences as an evaluation tool of public policy, complemented by other techniques of statistical analysis. The study seeks to confront social indicators of municipalities covered by the policy with other municipalities not served by this action, in periods before and after the government intervention. In this context, the results of five different scenarios are presented, conformed from different estimation techniques, groups of municipalities and variables. In addition to the impact estimations, tourism government representatives were interviewed. Briefly, tourist municipalities represent a positive increase in income indicators, although its impact on the reduction of inequality has not been identified. Therefore, it can be inferred that social potential of tourism has not been used as a broader conception of this phenomenon supposes. A set of interpretations for the results obtained is presented and discussed, pointing an extensive range of expectations for the touristic development. Recent reformulations in the normative framework of the tourist municipalities suggested that monitoring the developments of the main tourism policy at state of São Paulo remains necessary. It’s consistent, especially under the stimulus of competition between municipalities that have unequal resources for the promotion of tourism. Therefore, the reflections on what is the role of activity for local development and who are the actors that matter in this process remain while a fundamental task in tourism studies and indicate that social inequalities should be focused.

Compiler error messages should allow programmers to understand and solve quickly problems found during the compilation process. However, compilers usually issue short contextless messages with little information and with terms that are difficult to understand. This work introduces the plug-in Error Message System (EMS) that allows the presentation of easy-to-understand and more meaningful error messages. EMS is a plug-in to the Eclipse IDE. It is highly configurable through Domain Specific Languages (DSLs). The DSLs allow that regular users build their own error messages and share them. Beginner programmers can use a set of error messages adapted to them thus reducing the time of understanding and correction of compilation errors.

This research, of qualitative approach, aims to analyze the writings of future Mathematics teachers about teaching while they are inserted in the context of the Institutional Program of Initiation to Teaching Scholarship (PIBID). It was conducted by the following research question: How is teaching expressed in the writings of future Mathematics teachers while they are inserted in PIBID? To contextualize the research, a historical survey on teacher training in Brazil was made, and a brief PIBID history was also presented. The research relied on theoretical contributions on the importance of practice in the teacher training process and also on the issue collaborative partnership between school and University. As the focus of the research was to analyze the writings of future teachers, the instrument used for data collection was the portfolio, prepared by PIBID undergraduates. Thus, the literature on the importance of writing in the teacher training process was consulted and the concept of portfolios and their purpose in the initial training process of teachers were studied. Therefore, thirteen portfolios were selected for pre-analysis, from which six, related to three undergraduates, were analyzed through categories within four axes of analysis: (1) of personal character; (2) related to classroom; (3) related to students; and (4) related to school and/or to education. As a result, it is inferred that future teachers have a broad understanding of teaching while they are inserted in PIBID, extensively expressing teaching in their writings through the four axes of analysis, highlighting the following categories: pedagogical knowledge; experience; planning, adaptation and improvisation; socialization; contextualization; use of resources and technologies; adversities; student learning; evaluation of learning; discipline; lack of resources; and intention of education.

The proposed investigative work within the PPGQ - Professional Master - Chemistry Teaching UFSCar, proposes to use as a teaching methodology using the teaching kit as a motivating tool for learning of high school students. The objective of this work is to verify the student's motivation for learning using the teaching kit as a tool and reinforcement to learn basic fundamentals of chemistry, and the relevance that link to this stimulus, and how they evaluate this feature as a methodology for teaching learning. We as a theoretical framework that justifies and directs the research, the theory of David Paul Ausubel on Meaningful Learning, and Vygotsky's theory on the socio-interactional. We propose to carry out the studies and research comparing students' motivation for teaching and learning in classes that only use the methodology exhibition to teach and motivate students to learn, and the so-called methodology of ludo-educational, with the use of an educational kit chemistry developed with the purpose of teaching the basic concepts of chemistry, such as conductivity test, measures pH, precipitation reactions, acid-base reactions, redox reactions, chemical complexation reactions and chemical reactions in general. They participated in the experiment 20 students of the 3rd year of high school at the State School "Alvaro Guião", located in São Carlos - SP. We discuss the use of the teaching kit or play experimental activity in the classroom, as a support tool and complement the theoretical and lectures, and motivate students to learn chemistry in a process involving the student and the teacher and student with another student. Completing and learning the concepts, and motivating the student to explain how they understand life, the concepts and express what they feel, and possible limitations that may have. While using the educational kit, the experimental activities, was given will give continuous monitoring, and explanations on using the kit. And at the end, it applied a questionnaire approved by the Ethics Committee of the Federal University of São Carlos - Ufscar, assessing the student's motivation for teaching and learning, its limitations, conclusions and motivations concerning the use of the teaching kit and experimental activities, compared to lecture. Believing that the student, and the teacher, to understand the proposed work, eventually achieving their teaching-learning objectives of a motivated way. Those involved in research expanded the competence for the initiative, autonomy, creative capacity, teamwork, increase the interest and motivation for chemical content, expanding the understanding and learning different and attractive way to understand the use of this methodology as aggregating form and Additional lectures in chemistry.

In a previous study conducted by our group, it was noticed that fluoride (F) can induce changes in the expression of several liver proteins. Reports in the literature suggest that the changes caused by F in the body are dose- and time-dependent. The objective of this study was to analyze the effect of different F concentrations, exposure time to this ion and concomitant exposure to a high calorie diet in the metabolism of lipids and protein expression in the liver of rats. The study was divided into 2 steps. The first step included 72 21-day-old male Wistar rats that were divided into 2 groups (n=36) according to the diet administered (AIN-93M and Presence). Each group was further divided according to the duration of the treatment (20 or 60 days). In addition, each these was divided into 3 subgroups (n=6), according to the concentration of F administrated in the drinking water, as follows: 0 mg/L (control), 15 mg/L or 50 mg/L. After the experimental period, the animals were anesthetized and the liver and blood were collected. F analysis in plasma and liver tissue was done. Part of the liver was fixed for histological analysis. Lipids were analyzed in plasma and triglycerides were analyzed in the liver. Expressions of proteins were evaluated in the liver by Western blotting. In the second step the only Presence diet were use and the groups experimental the same as previously described. At the end of experimental period, liver and plasma were collected. F concentration in plasma and liver were analyzed. Liver proteins were extracted and prepared for mass spectrometry analysis. Proteins were sequenced and identified. The analysis of F concentrations indicated a doseresponse increase in plasma, regardless the time of exposure to F and type of diet. F concentrations in the liver were higher in the groups receiving 50 ppm F in respect to control. Administration of F altered the lipid profile, with a reduction in TGA in plasma and increase in HDL when the hypercaloric diet was used. The expression of GRP78, ERP29 and SOD2 and Apo-E was altered by F, under the influence of time and type of diet administered. For the groups receiving 50 mgF/L, it was observed an increase in the concentration of proteins related to the defense against oxidative stress and ER stress. For the group that received the concentration of 15 mgF/L, changes in structural proteins, mitochondrial proteins and proteins related to cell proliferation were observed, depending on the time of administration. The results suggest an adaptive mechanism of liver upon exposure to F, which seems to be related to the activation of proteins related to maintenance of homeostasis and that fight against oxidative stress and ER stress caused by this ion.

The enhance of the Unified Health System (SUS) in this country is still a challenge for the Brazilian public health, in order to allow the health services access for the whole population, with a good care quality, which includes the difficulties that homeless people have to be cared at the health services in this national territory. Despite that aforementioned population is numerically greater in the metropolis, nowadays even at medium-sized cities, such as São Carlos, there are people in this condition, justifying this city’s choice as the research field. This work aimed to analyze the caring practices and the conceptions of the homeless population in the city of São Carlos, from the speech of health professionals that work with that. Thereunto, social research methodology has been utilized, having as a tool the semi-structured interview, the focal groups with sixteen health services professionals from SUS who work with the health care for the homeless, and a representative of the specialized service for the homeless population from the Unified System of Social Assistance. For analyzing the data, the Content Analysis techinique has been used. In the light of the vulnerability concept and articles about the SUS and the homeless population care, five major content categories were discussed, extracted from the interview/focal groups. These were: Conceptions about the homeless population; Conceptions about the homeless population’s health care; Care provided to homeless population’s health; Knowledge about the network and intersectoral approach; Training for professionals to take care of the homeless. It has been argued that there is a need to occur a permanent education process for the workers, about the multiple intrinsic aspects of the street population caring. And that the municipal, state and federal managements enable the adequate working conditions, so that this work may happen with quality.
