This thesis is dedicated to the unveiling of the building game of the Brazilian political and economic possibilities in the recent period taking into account a specific period of national political and economic debate between the presidential elections of 2002 and the first year of the Lula government. We start from the premise that such possibilities, through establishment of truths, strengthen themselves from the interplay of forces produced in the economic and political fields whose success depends on the degree of strength of actors, groups and institutions in the scenario of dispute. We look back on the debate occurred around the financial rules discussed in the National Congress, which extends and is gain ground in elections for the presidency of the republic, where Lula and Serra would dispute the first and second round. Economic issues are discussed in the light of the broader issues that concern a more general situation of planning of Brazilian society, demonstrating how this debate is part of a dispute that goes beyond economic and political issues, it really concerns the cultural order to be legitimized. In this context actors, groups and institutions, from their capital, articulate themselves in the construction of possibilities, establishing criteria of truths that conform the interpretive lens of reality, interesting point to check the trends to which is subject to Brazilian society.

Endothelial dysfunction has been considered a marker for the presence of cardiovascular disease. It is characterized by decreased release of vasodilatory factors and increased of vasoconstrictors factors. Nitric oxide (NO) is the main endogenous vasodilator molecule that regulates the vascular tone and homeostasis. Decrease in the bioavailability of NO can be caused by a variaty of factors, including the increase in the production of superoxide radical O2 •-. The production of O2 •- can be stimulated by angiotensin II, by the enzyme complex of the NADPH oxidase activation. Thus, the objective of this work was to study the effects induced by ruthenium complex cis-[Ru(H-dcbpy-)2(Cl)(NO2 -)] (DCBPY) and sodium nitroprusside (SNP) in endothelial dysfunction model, as well as perform the pharmacological characterization of the dependent effects removal of O2 •- and release of nitric oxide (NO) induced by these drugs. Normotensive (2K) and hypertensive (2K-1C) wistar rats were used. Aortic rings with intact endothelium were placed in a myograph and incubated with DCBPY: 0.1; 1.0 ou 10 μM ou com SNP: 0.1; 1.0 ou 10 nM during 30 minutes. Curves concentration-effect of acetylcholine (ACh) were built where it was possible to analyze all concentrations DCBPY and NPS improved relaxation induced by ACh. NO was measured intracellular (for DAF-2DA probe) in HUVEC treated with 0.1 μM of DCBPY, 0.1 nM a SNP and 0.1 μM DETA-NO. It was not detected NO release of the compounds DCBPY [0.1 μM] and SNP [0.1 nM]. It also evaluated the release of NO compound DCBPY using an electrode selective for NO. The compound DCBPY spontaneously release NO in solution form concentrationdependent, starting from 10 μM concentration. DCBPY released more NO in the presence of cells. This could be due to the reduction of the compound by reducing cell. Intracellular detection of superoxide radical (O2 •-) was obtained by using the fluorescent probe (DHE). Our results show that treatment of cells with DCBPY [0.1 μM] and SNP [0.1 nM] decreased the fluorescence intensity cells stimulated with angiotensin II. Thus, it is suggested that DCBPY and SNP at a concentration which does not release NO, inside the cells, they are capable of attenuating endothelial dysfunction by inactivating superoxide.

Neste ensaio, exploramos as distinções teóricas e complementaridades metodológicas existentes entre abordagens que conceitualizam as estruturas sociais com base nas noções de campos e redes. Essas perspectivas se opõem tanto à visão atomizada quanto à supersocializada da ação e buscam superar a dicotomia entre estrutura e agência, mas possuem diferenças conceituais importantes. Aspectos epistemológicos e conceituais são discutidos, evidenciando que apesar de ambas serem consideradas relacionais, elas evitam a reificação da teoria de maneiras distintas. Apontamos que a forma como a noção de campo é utilizada por autores como Pierre Bourdieu e Neil Fligstein é articulada em um referencial teórico relacional, no qual a definição da estrutura é inseparável da de agência e do poder, possibilitando a superação de limitações da abordagem de redes. Enfim, argumentamos que o uso das técnicas de análise de redes pode ser orientado pelas teorias de campos.

Infiltration wells are BMP that occupy small urban area in order to minimize the effects of urbanization and soil sealing. The BMP reduces the frequency of flooding in urban areas. The present study aims to evaluate the behavior of two infiltration wells. One (Poço1- SC) was constructed with concrete rings get laterally together with the soil without the use of lateral holes and with a granular layer at the bottom of the BMP. The other (Poço2-GHidro) comprises the use of lateral concrete rings, a granular lateral and external layer external to improve the distribution of water, a filter of geotextile in the cover, and additional filters at the bottom and at the lateral wall between the gravel and soil. The experimental program involves the soil characterization, monitoring and modeling of real and simulated rainfall events imposed two systems. In addition, physical clogging tests were conducted in order to provide the understanding of the behavior of the geotextile filter applied in infiltration wells in order to estimate the service life. After two years, significant differences between the hydrological behaviors of the two infiltration wells were not identified and significant indication of clogging, was not observed. The calibration of the Puls model applied in modeling was employed using constant and variable hydraulic conductivity (K) values. In both wells the model showed more satisfactory results when variable K is used. This was observed for both the real and simulated events. In physical clogging tests, it was concluded that the solids particle distribution presents in rainwater runoff has a significant effect in the behavior of geotextile filter. The estimated average of service life of the filter in the Poço2- GHidro, at the conditions in which it is imposed, varies from 31 to 71 years, which depends on the type of soil in rainfall water runoff.

This research aims to propose a methodology for accessibility evaluation in middle-sized cities presenting a case study held in São José do Rio Preto (SP), city in the northwest of the São Paulo state. For this, the research used is based on a quality indicator (SQI – Sidewalks Quality Index, developed by Ferreira e Sanches, 2001). The questionnaires application in wheelchair users allowed the information collection in a qualitative and quantitative level regarding of security, comfort and environment in sidewalks and crossings and the carry through of a technical evaluation in the central area of the city. From these steps, as a methodology proposal, it was possible to elaborate an Accessibility Evaluation Index (AEI). This index was applied in the central area of the case study and an auditing (validation) was realized in order to verify the correct elaboration of the index. The present research was applied in a middle-sized city, the city type that has the fastest currently increase (IBGE, 2010), making the index an important accessibility evaluation tool. Thus, it grants the correction of identified accessibility problems avoiding the formation of cities whit segregated spaces, in people with some type of deficiency, with reduced mobility or elders do not have access to the city.

Find fair (according to some criterion) prices for assets in financial markets is one of the most important pillars of Finance Theory. To accomplish this, the Asset Pricing Theory has a mathematical formulation, based mainly on Probability Theory. In this dissertation we present such theory, which is essentially based on mar- tingales, important objects of Probability Theory. Alternatively, we also present an Asset Pricing Theory based on the Coherence Theory of Bruno de Finetti in order to compare, informally, such approaches.

Odorant-binding proteins (OBPs) are of great importance for survival and reproduction since they participate in initial steps of the olfactory signal transduction cascade, solubilizing and transporting chemical signals to the olfactory receptors. A comparative analysis of OBPs between closely related species may help explain how these genes evolve and are maintained under natural selection and how differences in these proteins can affect olfactory responses, and consequently lead to species differentiation. We studied OBP genes in the closely related species Anastrepha fraterculus and Anastrepha obliqua, which, albeit generalists, have different host preferences, using transcriptomes and real time quantitative PCR data. We identified 24 different OBP sequences from Anastrepha fraterculus and 25 from A. obliqua, which correspond to 21 Drosophila melanogaster OBP genes. Phylogenetic analysis separated Anastrepha OBPs sequences in four branches that represent four subfamilies: classic, minus-C, plus-C and dimer. We found evidence of positive selection in three classic subfamily genes OBP56h-1, OBP56h-2 e OBP57c and in the plus-C subfamily gene OBP50a, and at least one duplication event that preceded the speciation of these two species. Four positively selected sites putatively resulted in radical changes in amino acid properties. Inferences on tertiary structures of putative proteins from these genes revealed that at least one positively selected change involves the binding cavity (the odorant binding region) in the plus-C OBP50a, which is important because changes in the binding cavity could change OBPs specificity. Differential gene expression analysis at different reproductive stages showed that all nine OBP genes tested were significantly differentially expressed between A. fraterculus and A. obliqua at several reproductive profiles, but OBP56a, OBP56d, OBP57c and both OBP56h paralogs showed the highest differences in expression levels. The results generated in this study indicated that at least seven OBP genes may be involved in the A. fraterculus e A. obliqua differentiation, and in the fraterculus group differentiation as well.

Childhood is characterized by a development process in which the play is essential for the quality of life. Nevertheless, in hospitalization, studies indicate changes in the performance of the play, and consequently, the quality of children's life. It was proposed to assess the child's quality of life during hospitalization. This is a descriptive, cross-sectional research, which proposed to compare two groups, one (Group 1) in the absence of toy room or permanent toy in pediatric ward and the other (Group 2) in the presence of toy or toy room in the pediatric ward. Twelve children were interviewed, 8 belonging to Group 1 and 4 to Group 2, aged six to 12 years, it was used the Autoquestionnaire Qualité De Vie Enfant Imagé (AUQEI), as well as interviews with the participants and their responsible ones. The results revealed in Group 1 the possibility of interaction and play among children, different from Group 2 in which it was noted restrictions on single room (bed-box). As to permanent toy, it was not observed effectiveness regarding access and use on free demand, obtaining satisfactory results in relation to play in the service of occupational therapy. It was found that children who play reported positive feelings (happiness) during the hospitalization experience. In AUQEI scale, it was verified in Group 1 that 37.5% of children have had damages in the quality of life, being the average 49.5 with P.D. = 5.88, above the cutoff of 48 expected to satisfactory quality of life. While in Group 2, the damage was appointed in 75% of the cases, with an average of 46.5 with P.D. = 4.65, that is, below expectations. Statistically, it was not observed significant differences by the Mann-Whitney test (5%) between the comparison of groups, being not rejected the hypothesis that the groups are equal, however, it is considered the particularities and diversities of the groups. The AUQEI instrument showed good psychometric properties when applied to the two groups. The study shows the establishment of a positive relationship to the sense of well being and quality of life for children who play. Moreover, it must be considered the clinical condition, the subjectivity of the way to understand and face this experience and the importance of play, especially as the stimulus. Therefore, it is necessary to expand the look, be careful and sensitive to everything around a hospitalized child, consider that the toy itself often needs incentives to become play, or that even without the toy, playing can be explored and meet the child's whole needs.

The ethanol accumulated in the broth during fermentation is the main component toxic to yeast, causing slower yeast growth and decreased ethanol production. One way of overcoming this inhibition effect is to use extractive fermentation, where the ethanol is removed from the broth during the fermentation process. The present work evaluated sucrose ethanol production using extractive fermentation using CO2 as stripping gas. Firstly, it was made investigation of the influence of specific CO2 flow rate, initial ethanol concentration and solution temperature on ethanol stripping by CO2. At this stage the modeling of the of ethanol and water removal was achieved by CO2 stripping according to a first order model. In sequence, it was studied the production of ethanol by extractive fermentation in batch and fed-batch modes, employing in a 5 L bubble column bioreactor and temperature of 34.0 °C. The kinetic parameters of the hybrid Andrews-Levenspiel model were estimated by modeling of conventional batch and fed-batch fermentations (without stripping) with CS0 of 180 g.L-1. Mathematical modeling of extractive in batch and fed-batch ethanol fermentation was developed considering the removal of ethanol and water, due to the CO2 stripping, according to a first order model. Later it was optimized the production of ethanol by extractive fed-batch fermentation. A genetic algorithm was used to simultaneous optimization the substrate feed rate (F) and the ethanol concentration (CE0) to start CO2 stripping in extractive fed-batch fermentation, so as to obtain the maximum ethanol productivity. The ethanol removal by stripping with carbon dioxide can be modeled as a first order model. The hybrid model of Andrews-Levenspiel was adequate to describe the kinetics of batch and fed batch ethanol fermentation. The proposed model for extractive ethanol fermentation with CO2 was adequate to describe the behavior of extractive fermentation in batch and fed batch modes. In the extractive ethanol fermentation with CO2 stripping an increase in substrate uptake rate (rS=−dCs/dt) after the beginning of ethanol stripping and the total consumption of the substrate occurred before the extractive fermentation compared to the conventional process. The extractive batch fermentation with CS0=180 g.L-1 and CO2 stripping initiated after 3 h of fermentation at an ethanol concentration of 43.3 g.L-1, resulted in an ethanol productivity (in g.L-1.h-1) about 25% higher than conventional batch fermentation. For fed-batch fermentation, vat filling time (Ft) of 5 h and start of ethanol stripping at 3 h of fermentation substantially reduced the inhibitory effects of the substrate and ethanol on the yeast cells. This condition enabled the extractive fed-batch ethanol fermentation to be performed using substrate concentrations of up to 240 g.L−1 in the feed. The total ethanol concentration reached 110.3 g.L−1 (14 °GL) (wine + entrained). The use of the optimization tool enabled using substrate concentrations of up to 300 g.L-1 generating a total concentration of ethanol of 17.2 °GL (wine + entrained), which means an increase of 65% compared to the concentration final ethanol obtained in conventional fermentation without stripping.

This study evaluated the agronomic efficiency of application of powder of silicate rocks as potassium sources in consecutive crops of millet and alfalfa in a greenhouse experiment. The rocks Biotite Schist (BX), Syenite Ceraima (TA15), Mafurito Acreuna (TA21), Syenite SANW (TA20), Biotite Gneiss (EL02), and Phonolite Curimbaba (FN) were applied as slowreleased potassium sources in three doses 1.25; 2.50; and 5.0 g kg-1 of ground rock. Potassium chloride was used as standard fertilizer in doses of 0.10; 0,20; and 0.40 g of KCl kg-1 of soil. The soil used in the experiments was a Latosol, with 1.2 mmol dm-3 of potassium content. The TA21 rock was tested with and without soil acidity correction (TA21WL). In order to evaluate the rocks K reliase, five consecutive crops were performed: (1) millet (62 days of planting); (2), (3) and (4) Alfalfa (80, 115 and 155 days of planting, respectively), and (5) with 80 days of planting. The dry matter yield in the alfalfa was significantly lower than that millet cultivation. The forage samples were HNO3 + H2O2 microwave assisted digested for K determining content. The samples of rocks were characterized by X-ray fluorescence, X-ray diffraction, scanning electron microscopy and particle size distribution. Afterward, extraction experiments with Mehlich 1, and different extraction times of acetic acid and fumaric acid 0.05mol L-1 were performed. Aluminium, Ca, K, Mg, Mn, Na, P, and Zn were quantified by inductively coupled plasma optical emission spectrometry (ICP OES) in all the obtained extracts. The method of ion exchange resin was also applied to evaluated the rocks, and K, Ca, Mg, and P were quantified. Potassium soluble was determined by flame photometry after extraction with hot water, according to with the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA) official method. For drastic extraction, two microwave assisted decomposition methods were evaluated: aqua regia and reversed aqua regia with H2O2. Aluminiun, Ca, K, Mg, Mn, Na, and Zn were quantified by ICP OES and the results, compared by using the paired t-test, presented no significant difference between the decomposition methods in the 95% range of confidence. The correlation between the extractors, the nutrients plants amount, and agronomic efficiency was evaluated from the extraction obtained concentrations and the amount of extracted potassium in crops. The use of lime in soils that received the addition of TA21 rock significantly influenced the absorption of potassium and was no effect on the release of K only when this rock was added to the soil without prior liming.treatment. The decreasing order of potassium extraction efficiency, considering the total applied in treatments and K extracted by plants was EL02> TA21-SC> KCl> FN> BX> TA20> TA15> TA21. The two developed decomposition methods showed a better correlation with potassium extracted from the EL02 rocks. The greenhouse study corroborated the extraction tests performed in the laboratory, which indicated that the EL02 rock is the one with the highest percentage of K release compared with the other evaluated rocks.

With this research, we explore the configuration of the new media, emerged from a network of blogs and social platforms like YouTube and Instagram. Knowing that nowadays there's a potentially available system for any user to produce, broadcast, consume and rework any kind of contents, it's possible to gather new relationships between audiovisual production and consumption, as well as what was understood as an audience. By observing networked conversation and the emergence of the new communicators in this contexto composed by blogs and social platforms, new comunication channels also emerge, and those are made possible by networked individualism (WELLMAN, 2002; RAINIE; WELLMAN, 2012) – this grouping around those new communicators is caused by, among a lot of common subjects, the consumption of the character of the self constantly created by this new communicator. With the analysis of the content produced by three new media communicators whose thematic focus is lifestyle and beauty – the Just Lia blog, important for its longevity on internet, and consistent online construction of the self, the YouTube channel Camila Coelho, where the YouTuber has created the “beauty guru” character and a large network of people interested in herself, and the Instagram profile @gabrielapugliesi, which stands out as a character of the new media, since the Instagrammer could create her network quickly and spread herself, along with her contents, among all contemporary communication platforms, being able to blur the boundaries between the tradicional mass media and the new media.

The processes of separation and isolation of Kraft lignin obtained have been insufficiently resear ched, since much of the lignin of liqueurs obtained industrially is burned for energy recovery and carbon sources in the industrial processes. Currently, with the technological innovation targeting the pulp and paper industries, it is increasingly importan t to obtain lignin in simple and economically viable way. In addition, it is very important to find conditions under which the proceedings begin minimum degradation into lignin structures. In this work, the concentrated liquor lignin from Kraft pulp proces s was precipitated in acid medium in different conditions of pH and variable times of exposure to acid conditions of precipitation. It was done later, ash analysis, calorific power, Scanning Electron Microscopy with X - ray Spectroscopy (SEM/EDS); Fourier Tr ansform Infrared Spectroscopy (FTIR) and Ultraviolet - Visible Spectrophotometry precipitated (UV - VIS) for the characterization of the lignins and the filtered, for the characterization of the soluble fractions. A general analysis of the results showed that the best yield has occurred in 15 minutes of precipitation time for the pH of 6.71 (less acidic) among all employees. In the second test, the precipitations were performed at pH 2, 4 and 6 and with a time of 5 and 15 minutes, in which was got better yields and lower salt content in lignin. It has been applied statistical analysis in all the results, which many of them were considered equal. Thus, the best case was considered carried out at pH 6 at the time of 5 minutes , since it uses less hydrochloric acid are to perform precipitation. In parallel, it has been done tests to assess the possibility of separate fragments of lignin and sugars. The preliminary tests were conducted with phenol, simulating the lignin, and glucose, simulating the sugars. In order t o carry out this separation was used cellulose acetate Hydrogel as stationary phase in a preparative scale. In the first test conducted in a time of 30 minutes, it was possible to observe that there was a clear separation of phenol and glucose. In the seco nd test, in which the parameters were refined, like the elution time (55 minutes), it was possible to note a great improvement in the separation. The test of fractionation was carried out in order to simulate future tests to improve the conditions of ferme ntation of residual sugar produced by hydrolysis of cellulose waste involved in the production of second - generation ethanol.

Education has always been considered by social movements, especially the black movement, as an important playing field to be included in their discussions, as it is understood to be a means of promoting awareness, appreciation and social inclusion. Therefore, the approval of Law no. 10.639 / 2003 and its guidelines, which amended the Education Law (Lei de Diretrizes e Bases, or LDB, in Portuguese), can be considered a new milestone in the history of education in Brazil, because they represent substantial changes that alter the country's educational policy and reflect profound social changes in the way our society is represented. Compulsory education about ethno-racial relations and the history of Afro-Brazilian and African culture in all primary and secondary education reverberates in textbooks and supplementary course material, seen as important tools that play a key role to promote the history, culture and identity of Brazilians of African descent and erradication of prejudices. It is understood that publishers occupy an important space, creating, editing and disseminating textbooks and educational material; in other words, structured spaces that permit the transfer of symbolic capital for the legitimation of discourse and the discussion of topics of interest related to social demands, dictating themes and directing debates. In this context, the objective of this study is to investigate the publishing market in the Brazilian context, identifying how changes in the legal field have impacted its dynamics, starting from theNational Textbook Program and the National School Library Program.

Cervical cancer is the second largest cause of deaths from malignant cancer among women worldwide. Many studies show the importance of the HPV virus in the onset of cervical cancer, but because of the monoclonal nature of this cancer, it is suspected that HPV infection may not be considered the only causal factor responsible for the development of cervical carcinoma. Studies have indicated that EBV may have a role in cooperation with the HPV16 tumor development. Such cooperation could influence the tumor microenvironment by creating a favorable niche for its progression. Cancer cells secrete enzymes that degrade the extracellular matrix (ECM). Such enzymes such as matrix metalloproteinases (MMPs) facilitate cell movement in tissues and induce the activity of growth factors that promote angiogenesis. Among the group of MMPs, MMP-7 seems to have a crucial role in the development of carcinogenesis, since its action has been associated with the cleavage and release of adhesion molecules important. In this sense, this study was performed to establish the relationship between the HPV coinfection / EBV and expression of MMP-7. They were examined immunohistochemically histological slides of cervical lesions biopsies of 60 patients aged 35 to 65 years. The samples were divided into high grade lesion and low grade and evaluated semiquantitatively by scoring system ranging from 0 to +++. Histopathological indexes the degree of injury were established. It observed a statistically significant association between high-grade lesion, the expression of MMP-7 and the presence of the HPV virus, with p = 0.007 at the junction portion squamocolumnar and p = 0.023 in the portion of the ectocervix. This correlation

In Brazil, where social issues arising from the structural inequality of a capitalist society did not lead to configuring a State of Social Welfare at any time in its history and that, moreover, it coexists with extreme levels of wealth concentration, encouraged the question about how, nowadays, this social issue is whether or not considered by occupational therapists. Understanding that occupational therapy is a profession that can direct its interest of study and involvement to the social inequalities and its problematics, and highlighting interventions and therapeutic-occupational propositions that occur with individuals who are on the margins of the social organization, this project made a proposal of research that goes back to the relationship between occupational therapy and the "social issues" in Brazil, focusing on the publications produced by researchers until March 2015, when data collection ended. The survey was conducted from the CNPq Research Groups Directory in the Lattes Platform, where occupational therapists researchers working in the occupational therapy subarea were selected in this directory. Then an assessment was held in their resumes on the same platform in order to gather all its productions in format of articles, books and / or book chapters, so that later those related to the subject studied could be selected. In addition to this source of information, all publications in this area in the two indexed Brazilian journals in the field were gathered. The aim was to bring together the production of researchers in occupational therapy with what has been brought in knowledge dissemination vehicles in the area. The data collected after the application of the inclusion criteria for the study were gathered in 112 texts of 155 different authors. The content thereof permitted to categorize and analyze what was produced in the academic area, allowing the apprehension of the theoretical foundation of the relationship between occupational therapy and social issues in Brazil. It is noteworthy that the productions on the theme intensified from the 2000s, and mostly cover the adult population. What has been proposed by social occupational therapy in Brazil and the authors linked to METUIA Project marks sharply the set of this production. Moreover, it is clear that professionals turn to the demands arising from the social question in Brazil, noting that occupational therapy has indeed tools and resources to do so.

Brazil is a country with a wide range of socais problems that need to be resolved so that it can be considered a developed nation. In this sense many social problems could be studied by public research in order to mitigate social inequality. This research aims to identify and understand the obstacles and possibilities for the formation of the research agenda of the public university demands from the local community. The methodology was qualitative and exploratory, which is outlined in literature and literature. The literature encompassed thematic as science, technology and innovation policy (PCT&I); channels of communication between university and society; social technology; and territorial development. The result of the survey pointed out as an obstacle to the construction of the university agenda based on the demands of local communities PCT&I developed based on international models; political control centered in the hands of a few actors, especially scientists; research agenda aimed at an international science, business or particular demands; lack of communication channels and strategies and exchange of knowledge between universities and local communities; little research on the research agenda of Brazilian scientists. As possibilities the search result pointed adherence by the PCT&I concepts such as: social technology; regional development; solidarity economy; social technology park; sustainable development; and actions as public policy development: municipalities, states (master plan) and urban planning.

Public policy incentives are essential to the effectiveness of environmental law and the preservation of services provided by ecosystems. In this context, Payments for Ecosystem Services –PSE programs remunerate environmental services providers through funds built from the user/polluter pays logic. This study aimed to evaluate the possibility of implementing a PSA program in Pirajibu watershed, Sorocaba -SP, and suggest suitable alternatives for the conservation of water resources in the region. To this end, secondary data were collected on public agencies. In addition, were analyzed pictures from the RapidEye satellite (Ministry of Environment-ME), and with the help of satellite images from Google Earth, processed in Quantum GIS 1.6 software- Open Source Information Systems Finally, field trips were made to verify the information found. The results indicate that there is difficulty identifying possible providers and calculate the opportunity cost of the land, since agriculture is a rare activity in the region. Regarding environmental services, there was a great potential of the Pirajibu –Mirim River for water supply. This watershed has been studied in more detail, its water sources were mapped and some of them diagnosed in macroscopic analysis in the field. The water sources are, for the most part, in particular areas, with water having satisfactory aspects. However, there is the presence of garbage, lack of identification, proximity roads and the lack of environmental compliance expected by the Brazilian Forest Code (Lei nº. 12.651/ 2012). This scenario shows the importance that public policy in Sorocaba-SP considers the recovery and protection of water sources, however, not directly compensating the owner. It is suggested that the model has the forecast works for soil conversation on dirt roads, in addition to a donation of inputs and technical assistance to owners interested in recovery. Also considering the characteristics of relief and zoning of the master plan, it is proposed to establish a Private Reserve of National Heritage - PRNP at the head region of Pirajibu -Mirim River. Finally, it is suggested the implementation of other tax incentive policies in the region, such as property tax reduction in suitable properties with economic and social use.
