The professional education for people with special educational needs intends to promote the development of the potentialities of these individuals, with the objective of supporting the complete exercise of the citizenship. It s necessary that the responsible institutions for the preparation for the work accept people with special educational needs. This opening can provide the implantation of real steps that minimize the social exclusion and facilitate the access for people with special educational needs to the work world. In a country with so many social inequalities, the inclusion of people with special educational needs in education programs for the work presume the enlargement of the presence spaces of these people in high and professionalizing schools, also in Technological Education Federal Institutions. In this sense, the study takes place in the setting of the special education public politics into the field of the professional education for people with special educational needs, with the focus in the Program TEC NEP (Education, Technology and Professionalization for People with Special Educational Needs) as a proposal of expansion of education and professionalization in the federal net institutions settings. The TEC NEP Program is a proposal for professional education implemented by the Special Education Secretary connected with the High and Technological Education Secretary intending to expand the offer of professional education, access and permanence in the work for people (young and adults) with special educational needs. The aim of this study was estimating how the guidelines proposed in the TEC NEP Program are being implemented in the federal net schools, through the perception of the nuclei coordinators. Twenty nine nuclei coordinators took part of this study. The data were obtained through the questionnaires sent by internet to the 32 schools which had, until 2005, instituted formal nuclei of the program. 29 coordinators nuclei filled and gave back the questionnaires. The data were analyzed quantitatively and qualitatively and synthesized to offer information about characteristics of the informers and institutions, description of the implementation of the TEC NEP Program in the federal net schools, selective process characteristics, registrations number of students with special educational needs, partnership support, strategies to aid the school inclusion for students with special needs, insertion in the work market, program financing, difficulties in implementing and managing, program impacts and suggestions and considerations brought by the informers. The results obtained after six years of implantation of the program show that its reach is still restrict, considering that in 20 of the 29 schools, the nuclei were implanted only within the two last years and only about fifth of the schools (32 amongst 144) had nuclei of the program. In 19 amongst 29 investigated schools, the nuclei coordinators reported that their schools had already former report of registration of students with special educational needs even before the implantation of the nuclei. The number of investigated schools with registration of students with deficiency raised for 21 in 2005. In the 29 schools investigated were notified 379 registrations of students with special educational needs. However, it s useful to stand out that 244 students with deficiencies (65%) were in courses of initial and continued formation which didn t demand scholastic level. Moreover, only 4 amongst 29 schools concentrated about 71% of the 379 registrations of students with deficiencies, showing the small reach of the program. 8 Therefore, it s observed that the number of registrations of students with special educational needs in the federal net schools is still little significant, what can be connected with the difficulties for the access and permanence conditions of this population in these institutions, since they only can entry through selective examination. The considerations of the coordinators appoint the necessity of taking measures to modify the structures of the schools, implant support services, review curriculum questions, re-define the evaluation process, provide teaching staff formation; it s necessary the involvement of the whole school community in the pedagogical project of the school. Through the reports of each institution, it s still perceived the priority necessity of eliminating prejudiced attitudes, adjust programs, offer pedagogic support, elaborate budgets for the nuclei and qualify continuously all the professionals that work in it. It was verified that the quantitative of students with deficiencies in these schools, even not so significant, is due to partnerships with ONG s (Not Governmental Organizations), what means the transfer of the government responsibility. Concerning to the leading to the work market, it s verified that some few institutions did the control of this datum and the lack of this information hinders a proper evaluation about the effectiveness of the program. It follows that the adoption of isolated measures for the creation of opportunities for access in the federal institutions will make not sense if it s not connected with the taking of steps in the Reabilitation, Education, Health and Transport areas, in order to allow the access and the permanence of these people to these institutions. Thus, it seems necessary a larger planning, accompaniment and evaluation about the measures proposed by the Program for the responsible organizations.

The hypothesis of a synergy between two hormones responsible for sodium conservation, aldosterone and angiotensin II (ANG II), explains the expression of a characteristic of sodium appetite, hypertonic NaCl intake, in a hypovolemic animal. Hypertonic NaCl intake can be induced in normovolemic rats that received a combined treatment of mineralocorticoid and ANG II at individual doses not sufficient to induce sodium intake (paradigmatic synergy test). Considering the motivation to specific sodium intake another characteristic of sodium appetite, the objective of the present dissertation was to find out a role for the interaction between mineralocorticoid and ANG II on the specificity of sodium appetite. Sprague-Dawley Holtzman rats (≅ 300 g b.w.) were housed with access to water and one or more palatable (0.01 M KCl, 0.05 mM CaCl2, 0.15 M NaHCO3, 0.15 M NaCl) or hypertonic (0.50 M NaCl) mineral solutions for ingestion. In two-bottle tests, a bottle contained water and another bottle contained either 0.01 M KCl, 0.15 M NaHCO3, 0.15 M NaCl or 0.50 M NaCl. In five-bottle tests, a bottle contained water and each one of the remaining four bottles contained either 0.01 M KCl, 0.05 mM CaCl2, 0.15 M NaHCO3 or 0.15 M NaCl, respectively. In sodium depletion tests, intact rats received each a 10 mg sc. injection of furosemide or vehicle followed by 24 h access to sodium deficient food and water. Then, food was removed and mineral solutions and water were offered for recording their intake (sodium appetite test). In the paradigmatic synergy test, the animals received daily single sc injection of 2.5 mg of deoxycorticosterone acetate (DOCA) or sunflower oil (vehicle) for three days and a left lateral cerebroventricular injection of 50 ng of ANG II four hours after the last DOCA or oil injection. Fluid intake record began immediately after ANG II injection and food removal. The daily intake record showed no preference for any solution or water when animals had access to five bottles. Sodium depletion induced a preferential sodium intake, with higher NaCl than NaHCO3 intake, in either two- or five-bottle sodium appetite tests. DOCA alone enhanced the daily 0.15 M NaCl and NaHCO3 intake, but did not alter KCl or 0.50 M NaCl intake in two-bottle tests. In the paradigmatic tests with normovolemic animals, ANG II combined to oil induced the ingestion of all three palatable mineral solutions (KCl, NaHCO3, NaCl) and water, in two-bottle tests, and preference for NaHCO3 in five-bottle tests. DOCA pretreatment enhanced only sodium solution intake, particularly NaCl intake, induced by ANG II in two-bottle tests (0.15 M NaCl: DOCA/ANG II = 24.5 ± 6.7 ml/120 min. vs. OIL/ANG II = 9.2 ± 1.8 ml/120 min.; 0.15 M NaHCO3: DOCA/ANG II = 17.0 ± 1.8 ml/120 min. vs. OIL/ANG II = 14.6 ± 2.1 ml/120 min.; 0.01 M KCl: DOCA/ANG II = 9.8 ± 1.9 ml/120 min. vs. 11.9 ± 1.2 ml/120 min.), and enhanced by 80 % the total sodium solution intake in the beginning of the five-bottle test. The combined effect of DOCA with ANG II on the induction of 0.50 M NaCl intake in a two-bottle test was replicated in our animals. The results from the paradigmatic synergy test are coherent with results from sodium appetite tests, suggesting that the mineralocorticoid may turn the effect of ANG II on mineral intake more selective to sodium intake. Thus, the combined ANG II and mineralocorticoid action could contribute to the expression of two characteristics of sodium appetite, not only the acceptance of hypertonic sodium solutions, but also the selective sodium intake.

The main goal of the present work is to describe the lithium ion transport mechanism in a hybrid (SPHP) and nanocomposite (NHP) polyelectrolyte based on complex conductivity analysis as a function of temperature. The chemical synthesis strategy used to produce a helical free-chain configuration of singlephase hybrid organic-inorganic polymer electrolytes was based on a simple non-hydrolytic sol-gel route. The SPHP resulting from this strategy showed a Tg of -79oC and its temperature-dependent ionic conductivity (achieved at temperatures higher than Tg) displayed an Arrhenius behavior. This remarkable behavior characterizes a segmental motion-decoupled polymer. An Arrheniustype behavior for ionic conductivity (σdc) and hopping frequency of charge carrier (ωp) were observed. The values of activation energy obtained for σdc and ωp as a function of the temperature was approximately the same (~ 0.2 eV), indicating that the dispersive conductivity, σ(ω), originates from the migration of ions. This relevant physical aspect is allied to the fact that the contribution to the dispersive conductivity appears to be governed by a nearly frequency independent dielectric loss, ε = A, which correspond to an almost linear frequency dependent term of the form, σ = ωε ( ω) = Aω, in the real part of the complex conductivity. Furthermore, we observe a high stability, of SPHP and NHP when applied in a large EC device (5 x 10 cm2) using WO3 (electrochromic) and CeO2 -TiO2 (counter-electrode ion storage) electrodes, both optimized and produced by Leibniz-Institut of New Materials (Leibniz-INM, Germany). The electrochromic device exhibited excellent color and bleach reversibility, high coloration efficiency (> 35cm2 / C) from the first cycle up to more than 60000 CA cycles, and a maximum constant rate of deintercalation / intercalation (Oout / Qin = 1). Its remarkable behavior and high stability render this material an excellent candidate for application in electrochromic devices.

The present research work relates with the musical formation subject of teachers from basic education initial grades and had as objective to discuss and characterize the musical formation of three teachers licensed in pedagogy, emphasizing the initial stage role (graduation course) of this formative passage professional professor. This inquiry methodology was placed in the Qualitative Research scope, approaching the Bibliographical Research, prioritizing the data collection related to the teachers musical formation by halfstructuralized interviews and using the analytical descriptive method for the collected information exposition. The first chapter presents the bibliographical revision on the thematic of the teachers formation in present time, emphasizing the formative passage different stages. The second succinctly delineates the active teachers musical formation working at the initial basic education grades throughout the years, since the Brazilian Normal Schools creation until the current pedagogy courses and, by its end, shows some correlate researches already carried out in the teachers initial musical formation scope, studies that aims at demonstrating how such formations are configured nowadays. The third chapter explicates the methodological ways covered by this study, as well as the interviewed educators profiles. And the last one brings the exposition and discussion of the collected information, which were classified and organized from five analytical categories: Artistic-musical formation in the pre-training phase; Specific musical formation; Initial musical formation; Complementary pedagogicalmusical formation comedy; and Teaching initiation. The data interpretation glimpsed that the initial musical formation is only one of the formative course stages, which supplies the necessary theoretical and methodology bases so that teachers start teaching and search for a permanent and continuous musical formation.

In this thesis are presented the development of flow injection analysis procedures with spectrophotometric detection for determination of furosemide, paracetamol and acetylcysteine in samples of pharmaceutical formulations. A flow injection system was optimized for indirect determination of furosemide monitoring the excess of sodium hypochlorite not consumed in the reaction with the furosemide using o-tolidine as reagent at 430 nm. The analytical curve was linear from 5.0x10-6 to 8.0x10-5 mol L-1 and the detection limit was 2.5x10-6 mol L-1. A RSD smaller than 2.0% (n=10) for 1.0x10-5 and 5.0x10-5 mol L-1 furosemide solutions and an analytical frequency of 60 determinations h-1 were obtained. Another flow injection system was proposed to determine paracetamol in pharmaceutical samples employing sodium hypochlorite and o-tolidine as reagents. In this flow system, sodium hypochlorite reacted with paracetamol and its concentration in excess was monitored with o-tolidine. After system optimization, the analytical curve was linear in the paracetamol concentration range from 8.5x10-6 mol L-1 to 2.5x10-4 mol L-1 with a detection limit of 5.0x10-5 mol L-1. A RSD of 1.2% (n=10) was obtained for 1.5x10-4 mol L-1paracetamol solution. The analytical frequency of the system was 60 determinations h-1. The otolidine and its products used in both proposed flow injection systems were on line destroyed using an ultraviolet lamp (λ=380 nm) and hydrogen peroxide solution. The reversed flow system was proposed for determination of paracetamol employing sodium nitrite as reagent. The product formed was monitored at 400 nm. The analytical curve was linear in the paracetamol concentration range from 4.0x10-5 to 1.1x10-3 mol L-1 with a limit of detection of 2.0x10-5 mol L-1 and analytical frequency of 45 determinations h-1. RSD smaller than 2% were obtained for 8.0x10-4 and 1.0x10-3 paracetamol solutions. A flow system injection procedure with spectrophotometric detection to determine acetylcysteine was developed. In this procedure, acetylcysteine reacts with Ce(IV) solution and the excess of cerium (IV) was monitored with ferroin at 500 nm. An analytical curve ranged from 1.32x10-5 to 1.35x10-4 mol L-1 with a limit of detection of 8.0x10-6 mol L-1 were obtained. A RSD of 1.4% (n=10) for 2.2x10-5 mol L-1 acetylcysteine solution and an analytical frequency of 60 determinations h-1 were obtained. Another flow injection system for determine acetylcysteine using bromine (Br2) as reagent was also proposed. In this system, Br2 chemically generated on line reacts with the analyte and its excess monitored at 400 nm. The analytical curve obtained was linear from 1.6x10-4 and 1.6x10-3 mol L-1 and RSD of 1.2 % (n=10) for 5.3x10-4 solution were obtained. The system showed the analytical frequency of 60 determinations h-1 and ascorbic acid solution was used to destruct bromine on line.

Nowadays, some projects of genomes of different organisms are being analyzed generating a great volume of data, which are stored in heterogeneous and distributed data sources. Moreover, there are available tools in the genome domain that also need to be integrated. Another problem is that the systems developed for these objectives do not offer all the support to the researchers, therefore in their majority do not possess flexibility and are of difficult expansion. The proposal of this work is the development of a software component framework, called FrameEST, developed with the most recent technologies of reuses, that structures and guides the development of different applications of molecular biology domain. The FrameEST is available for reuses of the applications: in the phase of modeling in a CASE tool and the phase of implementation as one plug-in in the Eclipse enviroment. A case study is used to illustrate the FrameEST reuse.

Anabaena spiroides and Microcystis aeruginosa are cyanobacteria that frequently bloom in Barra Bonita Reservoir. These floating organisms and the characteristic turbulence found at the reservoir exposure the cells to higher light intensities by lifting them from lower depths in the photic column to surface. The sudden exposure at higher irradiance could cause photoinhibition and photooxidation. This phenomenon could liberate high amounts of dissolved organic matter. This work aimed to investigate the carbon fixation photoinhibition in cells of A. spiroides and M. aeruginosa exposed to high irradiances, the chlorophyll photooxidation and the DOM released by cells of cultures differing in their physiologic state, after exposure to high irradiances through time at laboratory and field investigations. A. spiroides suffered photoinhibition and liberation of dissolved organic matter when exposed to irradiances higher than their EK during four hours as well as when exposed to irradiance of 2000 µmol.m-2.s-1 for eight hours. M. aeruginosa did not present photoinhibition in any case, however, their C14OD liberation was significantly increased. The higher indexes of C14OD excreted by theses cyanobacteria are not apparently due to cell damage. Hence it might represent an adaptation factor to higher irradiances. Similar results were found in experiments incubated in Barra Bonita reservoir.

This work describes the similarities and differences in the work process of treating ornamental stones, comparing this against two periods of time (1890-1950 and the present time), the technological stages and work organization in marble and granite companies of the past and of the present. Data collection was based on various research sources and qualitative techniques (systematic direct observation and oral statements) and quantitative research (survey interviews). It was verified that the local marble and granite companies - since the end of the XIX century up until the present time - are installed in the mercantile establishments that operate in the third main stage of the productive cycle of the ornamental stones, elaborating final products from unrefined or polished slabs that are supplied by third parties. The semi-craft work organization and arduous work conditions seem to be conditioned to the technology employed by these companies. Along the XX century, local companies underwent technological improvements and upgrading, using new equipment and tools that increased efficiency of the final treating process. However, such technological changes did little to significantly improve work conditions and to eliminate predominant manual work with mechanical tools; although the work has been disassociated with partial craft work, the worker s skills remains the basis of the work process. However, the local companies have been incapable of modernizing their work units, not upgrading their systems with relation to available technologies worldwide. Mechanization and automation of the process, already incorporated by many companies in this sector, could modify the profile of the variables afore mentioned. Nevertheless, the small local companies are incapable of substituting or upgrading their equipments due to their low capitalization level at the rate the market develops and presents equipment.

The studied lake (Lagoa Mayaca) is located in a preservation area at the campus of the Universidade Federal de São Carlos. With the aim of analyzing the dynamic and the taxonomic composition of the Chironomidae, samples were taken through a transversal transect in two different periods (dry and wet season), comprehending the phenological cycle of Mayaca fluviatilis Aublet, 1775. From a total of 27 Chironomidae taxa, it was verified that the most abundant taxa in the dry season were: Cladopelma, Caladomyia sp1, Caladomyia riotarumensis, Djalmabatista pulcher, Ablablesmyia (Karelia), Tanytarsus rhabdomantis e Labrundinia. On the other hand, in the wet season the most representative were: Polypedilum (Asheum), Chironomus, Goeldichironomus, Endotribelos, Tanytarsus rhabdomantis, Caladomyia friederi, Ablablesmyia (Karelia), Labrundinia e Cricotopus. The greater taxonomic richness and number of specimens were registered in the sampled sites where Mayaca fluviatilis was present, indicating that the presence of this macrophyte was very important for structuring the studied community.

This work has as general objective to analyze the profile assumed for university professors from the areas of social science belonging to the São Paulo State Universities (USP, UNICAMP and UNESP), as well their opinions and reactions a respect of the fast socialeconomic, politic and cultural transformations occurred in the country in the last decades, whose influences reflect incisively on the university institutions and on the positioning of themselves with relation to their proper intellectual condition. In a more specific way we searched during this research to answer the following question: "How the university professors conceive their functions and what type of intellectuals our public universities are forming?" It is a qualitative inquiry based in structuralized open interviews by the way of a script previously elaborated using the research problem. Besides the development of the interviews has became necessary a bibliographical study about intellectuals, culture, university, university professors and society, having as theoretical referential the classic treatment on the elected subjects above, in special, the analysis about the scientific field developed by French sociologist Pierre Bourdieu. The collected data could evidenced that the university professors see themselves as responsible for the critical and for the possible intervention in the society, the academic intellectuals are pointed as those that possess the function to commit themselves to certain practices and try to realize specific changes in the environment in which they are inserted, their work is to be intent to their proper position and how this affects their studies. When describing their functions and reflecting on the university objective in the contemporary society, these protagonists point with respect to the inefficiency of this new model of university, implanted after the University Reformation in 1968, which gives privileges to the scientific and technological development, in order to stimulate the economic growth of the country, for the formation of new generations of intellectuals that, impressionable with the reduction of the time of the intellectual work and the intense production of bureaucratic reports demanded by the State and by the agencies of research promotion, specializes each time more early, disabling a intellectual work, in the sense of critic, reflexive and politician.

The current projects of rainwater plumbing systems are extremely simple and present only one exclusive concern: to divert the rainfall from the place where it occurs to the drainage public system. In general, it s possible to verify that they do not attend even the word semantic meaning. The no existence of a coordinated set of action aiming at ampler results makes rainwater plumbing system unconcerned with the surrounding area, not composing harmonically with the urban site in particular, and the environment as a general form. Generally, designers expect only rainwater goes toward out of the site, and that is a good result of a good system. Due the lack of attention to the impact that generates and does harm to society, they ignore its potential as instrument of water building conservation. They do not assess correctly its capacity as a source of supply of so expensive and scarce water, according with its necessities, conveniences or limitations that can exist. Therefore, the goal of this study is to propose a new function for the rainwater plumbing system, in special for Ribeirão Preto municipal school buildings, becoming it from a passive to an active system of environment protection. With a proper and molded conception for this new proposal, the system must contemplate the aspects related to the reduction of the impacts caused by the civil construction activities on urban sites, its preservation and providing environment education for people and also, as an worthy water building management tool.

The behaviour of reinforced concrete precast beams is strongly influenced by the flexural stiffness of its beam-column connections, wherein there is interdependence between the nonlinearity of the moment-curvature relationship along the beam and the non-linearity of the moment-rotation relationship of the beam-column connections. In most of the existing researches on semi-rigid connections in precast structures, the main focus lays on the characterization of the flexural stiffness by performing experimental tests on isolated models of beam-column connections instead of tests on sub-frames, comprising beam and connections. In this research an experimental procedure was developed, wherein different theoretical equations based on the fixity factor of the connections were combined, allowing the integration between the stiffness of the reinforced concrete beam with the flexural stiffness of the beam-column connections. Therefore, by using this procedure it was possible to evaluate the semi-rigid behaviour of the beam-column connection, highlighting the possibility of carrying out just one test for the precast beam with its connections. The analyses of the experimental results indicate that the studied connection was capable of absorbing around 53% of the elastic beam-end moment at the ULS, compared with the situation of a full restrained connector, implying the increase of 170% of the positive mid-span moment of the beam. This level of semi-rigid behaviour for the beam-column connection can affect the global stability of skeletal precast concrete structures with more than five storeys in height. For this reason, the present research shows the need for further studies with the purpose of enhancing the analysis and the design of precast concrete structures for multi-storey buildings.

Continuous development of new and improved products is seen as a key factor for business survival and growth. A new product that satisfies consumer s needs in an efficient and opportune manner increases competitive advantage. New product development (NPD) process has a multidisciplinary and multifunctional character, demanding specialized kinds of technical knowledge, peculiar of different disciplines or functions. A successful NPD requests a good integration among these functions, so that an auxiliary tool that helps this integration can increase project s performance and, consequently, competitive performance. In this thesis an auxiliary tool for managing functional integration in new product development processes is proposed, based in three conditional factors (Context, Technological Positioning, Competences) and three dimensions (Communication, Coordination and Collaboration). The tool s proposal includes a discussion about these conditional factors and dimensions, describing how they can be used to acquire an adequate functional integration in new product development process. As a secondary contribution of the thesis, a discussion about a particular case of integration, the one between applied research and NPD project, is made, including a theoretical discussion and case studies.

This work studies the School Stipend Program in order to verify whether or not it has achieved the goals of guaranteeing that children attend school and acquire literacy. In addition, it examines whether or not school helps the social integration of children from lowincome families. In this regard, this research project about the School Stipend Program also analyzes the extent to which this government program on a federal level can be considered a strategy for the social inclusion of poor children and adolescents. The categories of the State, Social Policies, State shape the understanding of the questions of social inclusion and exclusion in a capitalist society. The empirical study carried out between 2005 and 2006 focused on the School Stipend Program in the city of Jaboticabal, State of São Paulo. This study followed the administration of the program from its inception, collecting data that allowed the researcher to get to know the schools involved in the program and to choose the one that had the largest number of participants in the program. After contacting the selected school, the administrators and nine teachers maintained a close relationship with the students who benefited from the Program. After identifying this children, six families were selected to be visited and interviewed. Among the most important results of this study was the finding that the Program is important for the everyday life of these families, reflected in the relationship of the family and the children and adolescents with the school and in the reaffirmation of the fact that the the school remains a reference for the education of individuals. At the same time, the School Stipend Program doesn´t provide significant changes in the expansion of the social network of family support. This income supplement, regardless of the fact that it has been considered modest, has not solved the challenges that limit the possibilities in the social realm since they are the result of structural problems unemployment and low income among poor families. Finally, the school is a reference for students, an essential social instrument for the strengthening of the social support network of the most Brazilian children and adolescents who live on the fringes of vulnerability in a constantly precarious state that can produce social integration.

The Pd(x)La2O3-Al2O3 catalysts were obtained by wetness impregnation of alumina with an aqueous solution of Pd(NO3)2 and were characterized by specific surface area and pore volume measurements (SBET e Vp), x-ray diffraction (XRD), temperature programmed reduction (TPR), metallic dispersion measurements, diffuse reflectance spectroscopy at the UV-visible region (DRS) and diffuse reflectance infrared Fourier-transform spectroscopy (DRIFTS) of adsorbed CO. The SBET and Vp results suggest that lanthanum is dispersed at the γ-Al2O3 surface without blocking the support pores with La addition up to 12 wt%. The TPR and DRIFTS-CO results for Pd/Al2O3, show that there is an increase in the PdO-support interaction and the formation of Pd0 surfaces where the CO adsorbs preferentially at the linear form if compared to bridged CO species. Pd dispersion results and DRIFTS-CO for the Pd/(x)La-Al2O3 catalysts suggest that with increasing La loading, there is a partial recover of Pd sites by lanthanum oxide species resulting in changes at the CO adsorption form and lower accessibility to Pd sites due to geometric effects caused by the presence of LaOx compounds at the surface of Pd0 particles. Pd dispersion data and the catalytic activity tests show that with increasing La content up to 12 wt%, there is a decrease in Pd dispersion, followed by an increase in the specific activity, an increase in TOF values and lower apparent activation energies for CH4 during steam reforming. The higher activity of this catalysts with increasing La loading can be related to the following factors: i) the formation of a fraction of sites with higher electronic density; and ii) the transference of species like O* from the support to the Pd surface, that would promote the removal of species like C* adsorbed at Pd sites with high electronic density. This will therefore result in higher activities and higher accessibility of CH4 to Pd sites.

Literature about childish aggressiveness has evidenced importance of schools prepare to cope with aggressive students more effectively, that demand a lot of teachers instructional and behavior management skills. The continuation of punitive practices, used in schools, can be result of teachers lack of skill to cope with children who show aggressive behavior. Otherwise that, application of proper behavior management strategies and the development of positive relationships among teachers and children contribute to promote social and academic success, especially to children at risk. Several authors have argued a comprehensive intervention applied in the preschool is the more effective method to divert these children of antisocial pathway. Necessary conditions in the school context to support teachers to cope with aggressive children have been the object of several researches. International literature has indicated positive effects by the application of intervention programs in the school context on aggressive behavior. These effects are: the decrease of aggressive behavior rate and improvements social and academic skills in children, and the teachers acquisition of skills to cope with aggressive children. It was verify the necessity of identify characteristics relative to teacher s role in intervention programs, referring to knowledge and skills required to support students, and relative to teaching strategies that are offered to teacher act properly. The present research intended to elaborate a capability proposal, derivative of successful school-based intervention programs revision, that promote the improvement of teachers skills, directed to prevent and/or minimize preschoolers aggressive behaviors. Method was divided in four stages: (1) search and identification of successful school intervention programs; (2) a wide description of each intervention program; (3) a specific description of skills and tasks that are related to participants and responsible professionals performance in the programs; and (4) the elaboration of a capability proposal for the improvement of teacher skills in coping with aggressive preschoolers. The main results consisted in four products: (a) identification of relevant skills to be developed by students; (b) identification of proper strategies to development of these skills; (c) proposition of a set of the teachers skills required toward implement teaching strategies which aim at prevention of aggressive behavior in classroom; and (d) proposition of conditions to be offered toward teachers. The aim of this study is to make available a capability proposal to preschool teachers, based on successful theoretical and experimental foundations provided by programs described in the literature. This product is considered to be important in the development of future investigations on the necessary teaching conditions related to the improvement of teachers skills in coping with children who exhibit aggressive behavior problems.

This work introduces a study of the implementation and running of the councils of popular participation related to the educational area in the Municipal Corporation of Araraquara. Since the possession of the affiliation designated as Democratic and Popular Front, in 2001, guided by the Workers Party (PT), and still formed by the Brazilian Socialist Party (PSB) and the Communist Party of Brazil (PC do B), the policy adopted is the decentralization one, assumed as being the best way for democratization in the public power scope. Since the beginning in 2001, the administration of the Democratic and Popular Front showed preoccupation in amplifying the spaces for popular participation. With the motto The Society Generating Public Policies , it instituted several Municipal Councils and restructured those who already existed. There are in this Municipal Corporation three councils directly related to education that were analyzed: the Municipal Council of Education, the Council of School Nourishment and the Municipal Council of Attendance and Social Control of the Maintenance and Development Fund of Elementary School and Valorization of Teacher Education (FUNDEF). Through the analysis of documents and observations in some meetings, the work searched for identifying elements for a discussion on the real representativeness that the society has in those councils, in the light of Norberto Nobio s theory on the development of the democracy in the complex current society. The promises non accomplished by the modern democracy, according to Bobbio, added to the essential stages of acting of the council, pursuant Perseu Abramo, were used as a basis for the proposed analysis. Initially, the text shows, briefly, from the historical passage of the Brazilian Politics, from the 60 s to 1988 (Enactment of the Federal Constitution), focusing on the issue of the education democratization in a national scope, after in the State of Sao Paulo and finally in the Municipal Corporation of Araraquara. Then, basing on the data from direct observation and documents, the text tries to demonstrate how the analyzed councils are introduced, their composition, attribution and the possibility of contributing to the democratization of the public administration and to the improvement of governmental policies.

The aim of this work is to assess in real time the morphological parameters of polypropylene and polyamide 6 blends during the extrusion process. An optical detector based on the visible light transmitted and extinction principle was assembled in a slit die located at the exit of a twin screw extruder in order to get the changes in the polyamide 6 particle concentration and size. The influence of particle size and concentration was first verified during bench calibration, where it was observed that the light extinction was greater the higher the concentration and the lower the particle size. In the case of mixtures an additional relation concerned to changes in size and density was verified. It was also stated that the detector records the ponderal average size of a set of particles. During extrusion experiments, the analyses were performed in the steady and transient state. In both cases it was verified that normalized signal intensity increases with increasing particle concentration and decreasing the dispersed phase size. Infrared analysis and images obtained from scanning electron microscopy confirmed these results. The correlation between dispersed phase concentration and size with the detector s normalized signal was established through the elaboration of regression equations. The plot of normalized signal as a function of the dispersed phase concentration and size enabled the calculation of the extinction cross section values for the PP/ PA6 blend.

The Itajaí river estuary, SC, is located in the final portion of Itajaí river watershed, which has a total area of about 15,500 km2. The terminal region of this watershed is characterized by the presence of important cities such as Blumenau and Itajaí. Agriculture is also important, specially irrigated rice culture. The aim of this study was to evaluate the spatial-temporal variability of water quality and the nutrient transport and transformation processes in the estuary. A weekly monitoring was carried out from october/2003 to december/2004, along seven estuarine sampling stations, one station in the Itajaí-Mirim river (the main tributary) and one reference station located in a undisturbed area. Activities included measurements of salinity, pH, dissolved oxygen, temperature and nutrients (NH4 +, NO2 -, NO3 -, PO4 3-, H4SiO4), biochemical oxygen demand (BOD), total and organic phosphorus (TP and DOP), particulate organic carbon (POC), suspended particulate material (SPM) and chlorophyll-a (Cla). The intratidal nutrient variations was also evaluated in the middle and low estuary, in december/1999. This survey included hourly measurements of the stream velocity, water level, SPM and nutrients in three fixed stations, during 25 hours (2 tidal cycles). Multivariate analysis showed that the main forcing factors causing the system variability were the river discharge, the marine influence, the urbanization and the rice culture. It was proposed that the system can be divided in riverine limit, and high, middle and low estuary. The urbanization was responsible by the spatial variation of the water quality, showing increases in the organic matter (BOD, NH4 +, POC and DOP) and progressive decrease of dissolved oxygen. Despite the effect of dilution by the marine waters, increasing in NH4 + was detected in the low estuary, which is probably related to the urban organic loads and the fisheries processing plants effluents. When the river discharge was low during a long time, increasing in NH4 + and NO2 - and severe decreasing in dissolved oxygen was observed. This situation could be an early indication of hypoxia in the estuary. River discharge increasing resulted in increased SPM, TP, NO3 - and Si. This trend was intensified by high soil exposition in the beginning of the rice culture cycle. In this period there was a decreasing in Si, suggesting influence of rice culture Si uptake. The nutrient budget showed that 50% of PO4 3- input was shifted in the middle and low estuary. This was probably related to adsorption to SPM, once chlorophyll-a in the estuary was relatively low. The non-conservative increase of NH4 + in the low estuary suggest a heterotrophic behavior, once the organic load and turbidity were generally high. The intratidal variation of nutrients showed to be lower than other regional estuaries and also seemed to be influenced by the surrounding area. The tendency of non-conservative increase of NH4 + was also evident and related to salinity values between 5 and 15, which occurred during the water mixing inside the estuary.

Rosário Farm was founded in 1940 by Russian educator Helena Antipoff as a boarding school for receiving exceptional children from Belo Horizonte. Our study analyzed the pedagogical practices of that institution, verifying how those attitudes reflected in inmates life. First, we introduce Antipoff s path, understanding her educational principles as well as her motivations to come to Brazil in 1929. After that, we follow her performance next to teaching system of Minas Gerais capital in 1930 s, and her path during the creation of institutions for educating children as she called exceptional , including of Rosário Farm. Finally, based on learning the Rosário Farm history, we examine children profile, the pedagogical actions, the course of inmates, their reactions to institutionalizing process, testifying the work became the thread of those relations. After a study of adopted work conditions as educative principle, we weave a review of the way of teaching and performance junction happened in the institution.
