    The water for many years was considered inexhaustible, and only in recent decades, became aware of the shortage and the need to rationalize their use, look for ways to reuse and recovery of its quality. In this search context for reuse alternatives, the use of treated sewage sludge in agriculture can become an important tool in water management. Therefore this study evaluated the production of lettuce (Lactuca sativa L.) using hydroponic reuse water from sewage treatment plant. The experiment was conducted at Agricultural Science Center - UFSCar, in Araras, SP, in the greenhouse. Crops occurred from February to March (summer) and July-August (winter) 2014. The hydroponic system adopted was the Nutrient Film Technique (NFT), three treatments, with the first supply of water and fertilizers (TA ), the second with sewage treated and supplemented with fertilizers according to results of previous chemical analysis (TRA), and the third only treated sewage (TR), distributed in four randomized blocks. Each treatment consisted of four plots (stands), a 500 L tank for storing the nutrient solution, a motor pump assembly and a timer. Four polypropylene hydroponic profiles with 3 meters long were used in each bench, with 48 plants per plot, totaling 192 plants per treatment. We evaluated the fresh weight, nutritional status and the microbiological quality culture, and the amount of fertilizer used in the treatments. The fresh weights were subjected to analysis of variance and means compared by Tukey test at 5% probability. Only the TR treatment showed a significant difference compared to the other, in which the plants showed symptoms of deficiency and have significant reduction in fresh weight (p <0.01). There was no detectable presence of E.coli in any treatment, and it was possible to obtain a saving of fertilizers in some of TRA compared to TR. These results suggest the feasibility of reusing water application as a water source for hydroponics, with the necessary corrections, and that the hydroponic profile can act as a barrier to prevent contact of the effluent with the lettuce leaves, according to the conditions and care adopted in handling.

    The loss of nests is the main cause of failure in the birds reproduction, so predation becomes an important component in the events related to life history adaptations. An adaptation widely recognized is the smallest cluth size in tropics than temperate areas. One of the main hypotheses that try to explain this fact is the Skutch’s hypothesis, which predicts that predation rates are higher in the tropics and increase according visitation rate of parental in nest. Predation is also commonly associated with decline of birds population in fragmented areas, the mesopredators release hypothesis is widely used to explain this fact. This hypothesis predicts that in fragmented areas the top predators are the first to become extinct, leading to an increase in the density of mesopredators, which increases the nests predation rate, resulting in a decline of birds. Thus, the main goal was to identify nest predators in Atlantic Forest using cameras trap, allowing to infer about some assumptions of Skutch’s hypothesis and "mesopredators release". During two breeding seasons 2013/2014 and 2014/2015 were found 154 nests of 28 species of birds, of which 41 were preyed (26.62%). The contribution of each type of predator (day x nocturnal) can be evaluated and corroborated with the premise of Skutch’s hypothesis, they are mainly diurnal predators. There were no differences between the stages of the nesting cycle (incubation and nestling), so it was not possible to relate the predation with the activity of parents. The predation rate for the study area was low when compared with other studies, this can occur due to the area be well preserved and continuous, unlike most studies that are conducted in disturbed areas. Mostly identified nest predators are part of the diet of top predators, but there is indirect evidence (diet) that the smaller cats are probably more important to control density of nest predator, like small marsupials. Although the birds are not commonly quoted in these studies, they contributed greatly to the predation rates presented, reinforcing the importance of further studies on the birds fit in this context.

    This dissertation sought to investigate the applicants educational processes of social practice of collective musical creation. Through the research presented here aimed to analyze the educational processes generated from 5 collective musical creation activities for boys and girls in social project Tocando à Vida , from Ribeirão Preto, in order to identify whether these processes contribute to the formation these human male and female students. The collective musical creation activities such as social practices, understand that favor togetherness guided dialogue and collaboration, thereby, we seek to understand how these activities can contribute to humanizing music education. For research we propose to carry out the methodology of participatory research where data collection started from an insert within that space was adopted so that observations of these educational processes happen in contact with students and students during the performance of music creation activities collective. The Project Playing to Life, Ribeirão Preto SP provides free group lessons of musical instruments for children 06-13 years. The inserts in order to collect data occurred in the course of eight months, which participated in the activities of collective musical creation proposals 10 male and female students. The data collections were made by observing the activities, and wheels of talks held after the activities. As memory resources records in field diary and recording the wheels of conversations and musical creations of the students were used. The authors that guided the analysis were Paulo Freire, Ernani Maria Fiori, Enrique Dussel, Carlos Rodrigues Brandão, Hans -Joachim Koellreutter , Maria Teresa Alencar de Brito, Jorge Larrosa Bondia, among others. As a result it was possible to observe the changes in the relations between male and female students, with regard to the development of guided dialogue in loveliness, conquest of autonomy and the search for the humanization. The analysis of the educational processes that are generated social practice occurring during collective musical creation activities within the Project Tocando à Vida can contribute to change of view on this kind of activity, generating a favoring of human formation of children who learn music.

    Chronic Obstructive Pulmonary Disease is characterized by chronic airflow limitation in the lungs, dynamic hyperinflation, lung function deterioration and systemic manifestations. The worsening of the disease causes patients to insert into a cycle of inactivity, intolerance to exercise and progressive reduction of physical activity level (PAL) and ability to perform activities of daily living (ADL). Patients with COPD also experience exacerbations, which contributes to a worsening and progression of symptoms. Stable and post-exacerbated patients present psychosocial symptoms, such as anxiety and depression, which intensifies the cycle of physical activity level impairment. Therefore, the aim of this study was to compare anxiety and depression symptoms, PAL and dyspnea on ADL and verify the association between them in stable and postexacerbated patients. A cross-sectional study was conducted, which evaluated 13 patients in Post-Exacerbation Group (PEG) (68.9±9.5 years e FEV1= 50.5±18.7 % of the predicted value) and 27 patients in Stable Group (SG) (66.5±7.4 years and FEV1= 48.5±15.4 % of the predicted value). Hospital Anxiety and Depression Scale (HADS), London Chest Activity Daily Living (LCADL) and six-minute walk test (6MWT) were applied. During seven days, PAL was measured using a Yamax Digi- Walker SW-700 pedometer (Yamax, Tokyo, Japan) positioned at the patients‟ waistline; moreover, the patients responded to the International Physical Activity Questionnaire (IPAQ), short version. Shapiro-Wilk test were performed to verify the normality of the data. To verify the difference between groups, we used Student test or Mann-Whitney test and Chi- Square test was performed to verify the difference between nominal variables. For correlation analysis were performed Spearman´s and Person´s correlation. PEG patients had more anxiety symptoms (p<0.01), dyspnea on ADL (p=0.02) and lower steps on weekends (p=0,02). There were no correlations between anxiety and depression symptoms with PAH. In PEG, symptoms had a moderate correlation with dyspnea on ADL (r=0.67, p=0.01). In SG, symptoms had a moderate correlation with dyspnea on ADL (HADS-A: r=0.46, p=0.02; HADS-D: r=0.44, p=0.01). Thus, the authors concluded that post exacerbated patients are more anxious, presented lower PAH and more dyspnea on ADL compared with stable patients. Furthermore, dyspnea on ADL is associated with anxiety only in post-exacerbated patients and depression is associated with dyspnea on ADL in both groups.

    This study investigated the effects of bilateral intra-amygdala microinjections of PNU-282987, which is a nicotinic cholinergic agonist, on anxiety and emotional memory as well as the reversal of amnesia induced by an H1 histaminergic antagonist (CPA) in mice subjected to the elevated plus-maze (EPM). For this purpose, two experiments were performed. The subjects were seventynine adult male Swiss mice weighing 25-40g at testing. Behavioral testing was performed on two consecutive days (T1 and T2). In both experiments, the drugs were administered prior to testing. In Experiment 1, the animals received bilateral microinjections of saline (SAL) or PNU-282987 (0.1 nmol) and four experimental groups were tested; i.e., SAL-SAL, SAL-PNU, PNU-SAL and PNU-PNU groups. In Experiment 2, the animals received combined bilateral microinjections of CPA (0.16 nmol) and PNU-282987 on T1 and they were re-exposed to the EPM 24 hours later. Four experimental groups were tested; i.e., SAL-SAL, PNU-SAL, CPA-SAL and CPA-PNU groups. ANOVA followed by Duncan´s tests revealed no significant differences between the SAL and treated groups at T1 in the measurements of anxiety (i.e., % open arm entries and % open arm time, ANOVA, p > 0.05), which indicates that the CPA and PNU did not induce effects on anxiety. The isolated microinjections of PNU-282987 did not produce effects on emotional memory; however, the combined microinjections of PNU-282987 and CPA were able to reverse the deficit in memory induced by CPA (ANOVA, p < 0.05). There were no significant changes in the numbers of enclosed arm entries which served as a measure of locomotor activity (ANOVA, p > 0.05). Taken together, these results suggest that intra-amygdala injections of PNU-282987 did not induce effects on anxiety and emotional memory per se; however, the combined injections of CPA and PNU-282987 reversed the amnesic effects caused by CPA, which is suggestive of an interaction between the histaminergic and cholinergic systems in the modulation of emotion memory acquisition in mice subjected to the EPM.

    Currently, in Brazil, the assistance geared to workers who were affected by disease or accident, who find themselves unable to return to their original function, but have the potential to exercise other labor activities, is provided by the National Institute of Social Security (INSS) to taxpayers, through the Vocational Rehabilitation Program (PRP). Vocational rehabilitation aims to provide the necessary means for the worker s re-entry into the labor market. This research aimed to understand the INSS PRP s contribution to the employee s reintegration in the market and, as specific objectives, identify the profile of the population served by the program of the Social Security Agency (APS) of the Southeast, between 2007-2012; we investigated the means used within the program to reintegrate workers into the labor market; trace the professional profile of users who visited the PRP; and characterize, in the view of the rehabilitated workers, how the program interfered with their reintegration into the market. This is a case study because it was focused on a single APS among a vast universe, transversal and descriptive, which had as data collection 592 records of people referred to the PRP on the above period; besides having been performed eight in-depth interviews with workers considered rehabilitated. The results showed that the profile of the people served corresponds to 76.5% male, 61.15% of those aged between 30-44 years, the most natural of the host city of the Program or the same state, about 62 % are married or living in a stable relationship, 15% have some form of disability, 42% had not finished elementary school, 74.5% are affiliated to the INSS as employees, 99.5% receive social security benefits, and of these, 77,2% receive common sickness assistance. About 48.5% of people referred were eligible to join the program. As for the resources used in the rehabilitation process, in 5.33% of cases was fitting, 23.33% in the provision of courses, and 25% training in the bond company; no resource were used with the remainder. Workers considered rehabilitated by the organization totaled 34%; currently, according to information from corporate systems of the institution, of these, 49.02% are employed or are self-employed, Social Security contributors, and 26.5% are without bond. The in-depth interviews allowed us observe that the rehabilitated workers do not show a direct relationship between the program and their reintegration into the labor market, but they claim that the resources used in the rehabilitation process are important means to win, if not a job, at least recognition personal and The study points to the need for coordination between the INSS and companies to be forwarded to the rehabilitated internship or a job vacancy by the Institute; this, while federal agency, would have, in their view, the power to promote this articulation and guarantee them a job. The PRP requires changes, a more active attitude of the body at the end of the rehabilitation process, and fundamentally have not ceased their responsibility at the time the rehabilitation of the certificate is sent out.

    Cathepsin D is an aspartyl endopeptidase involved in many pathological processes when overexpressed. In addition, it is responsible for degradation of hemoglobin ingested by parasites of schistosomiasis. For these reasons cathepsin D is considered an important target for chemotherapeutic intervention. The assays commonly performed to evaluate the inhibition of this enzyme monitor reaction products generated from the cleavage of fluorogenic peptide substrates or human hemoglobin in the presence of inhibitors that may exhibit autofluorescence/absorbance at the same wavelength used. Considering this problem, this paper presents the development and application of four methodologies for cathepsin D assays. In two methodologies the assays were performed in solution, and in one of them was used isolated bovine cathepsin D, and the other employed an extract of proteins taken from Schistosoma mansoni adult worms. A third assay was developed to evaluate inhibitors by means of a CatD-IMER bioreactor coupled to a multidimensional system in which it is possible to monitor the immobilized enzyme activity directly by quantifying the product formed. Finally, the last methodology was carried out by immobilizing the substrate human hemoglobin in the quartz crystal. The hydrolysis of hemoglobin by cathepsin D was evaluated by using a Quartz Crystal Microbalance technique, a method that monitor the enzyme activity by mass variations. For the enzymatic assays, twenty plant extracts were evaluated, which led to the isolation and identification of the alkaloid evolitrine, the compound 4-hydroxy-3- methoxycinnamaldehyde and the flavonoids orientin and isovitexina. It were also tested 31 pure compounds, among them, the substance (Z)-2-(pentadec-5- enyl)benzene-1,4-diol, which showed significant activity both against the isolated enzyme as the protein extract of S. mansoni. Finally, recombinant cathepsin D from S. mansoni was cloned and expressed using E. coli system, and in vitro studies of isolated natural product compounds showed excellent results regarding the limonoid cedrelona against somules and adult worms of S. mansoni.

    Students with high ability or giftedness are known as the audience of the Special Education, supported by the legal provisions, which guarantee adequate educational attention for the full development of their potential and talents in an inclusive perspective. The school system of the State of São Paulo, which configures the Brazil‟s largest one, in accordance with national guidelines, states by its own public policies the recognition of the needs for specialized pedagogical care when considering this segment of students. However, it is not uncommon the invisibility of this school population, by numerous factors, such as myths, lack of knowledge on the subject, lack of public policies on Special Education, among others. Such problem involves the lack of educational responses, showing that there is a significant gap regarding the provision of education quality to students with high ability or giftedness. In recent decades the scene of the Brazilian education has passing through many changes, regardless the educational management follows the same direction. Therefore, an inclusive education requires a democratic and participative management, which contribute to the promotion of educational practices and administrative actions, such as the implementation of specialized pedagogical care services to meet the educational needs of all diversity of students. Then, the goals of this research are: i) to analyze the knowledge of the management team of an executive board of the State of São Paulo about the concept, forms of identification and provision of specialized educational services for students with high ability or giftedness; ii) to describe the provision of special education services offered in educational public policy, in the perspective mentioned above. To this end, it has used an exploratory descriptive research with a case study. This study included 22 managers of Educational Board of a city located in the state of São Paulo using a questionnaire to understand the profile of these professionals and the conception of the work on the thematic of high abilities or giftedness students. The results showed significant progress with respect to the legal standards for educational transformation in an inclusive perspective. However, the effects of these documents do not reflect in an egalitarian context for students with high ability or giftedness in the studied school network, specifically within the Board of participant education, since the results revealed that the issue of knowledge multiplication in the schools is incipient. It is inferred, therefore, that it is one of the factors that impacts the lack of attention to this portion of students.

    Currently, the academic community and teachers formation courses are still living a period of transition between educational performance models that are supported by regulations, such as the resolution CNE/CP n° 01/2002, which features the National Curriculum Guidelines for the Basic Education Teachers Formation. In these documents and also in research carried out, we try to overcome the formation focused on technical rationality. Searching the formation of a professional who is the author of your own practice and master and specialized skills. Considering this formation model, studies of teacher formation have as issues of interest to identity the teacher knowledge, pedagogical practice, professionalism, autonomy, among others. The formation process, which is for all teacher s professional life and even before it, has in degree courses an important moment of contact with the knowledge, practices and the constitution of the teacher identity. Therefore, questions about the initial formation, the knowledge and the desired professional profile on degree courses in Chemistry deserve further investigation. In this qualitative research, higher education institutions of the State of São Paulo were researched in order to investigate and analyze the initial formation of Chemistry teachers in Chemistry Degree courses. This picture of reality was subjected to a critical analysis supported by references that formed the basis for the discussion of possible paths to the initial formation of Chemistry teachers. For the analysis, data were collected on the sites of the institutions to known the profile of professionals in formation and on playing field. Also collections were made in seven institutions with teachers trainers and undergraduates. The analyzes point to a course profile which, despite being to form teachers, has as major goal the training of a skilled professional for the work in a diverse market, with little emphasis on teaching. Specific knowledge of Chemistry is prioritized by both undergraduates and by trainers who in turn give little attention to the pedagogical knowledge. A formation model is presented and discussed in order to contribute to the improvement of undergraduate courses in chemistry.

    Smart TV applications are typically disconnected from the content of the tuned programming on the TV set. Some broadcasters offer specific applications for programs, however, these applications are generally just loosely coupled or synchronized to the program. Furthermore, applications are fully under domain of broadcasters, that have the information about the transmitted content. Based on the fact that synchronized information may arise from third-parties, obtained by local content processing or offered directly by the viewers, new opportunities will be opened up for developing a bunch of new interesting applications aiming to promote the user interaction level in TV. Moreover, it will have new user interaction possibilities while using mobile devices and computers, furthermore a new business model will be emerged. In this master thesis, the SyncSmartv framework is presented and evaluated. The aforementioned framework offers several APIs that facilitate the development of Smart TV applications synchronized with TV program contents. The aim is to provide some facilities for developers to implement applications in this area in a clear approach without being concerned about low-level implementation details.

    This dissertation aims to analyze what are the social representations about the science and be a scientist present in two scripts of plays of São Carlos groups of theatre. Such social representations are not reproductions of surrounding the authors of the scripts. Cultural values are assimilated through a network built collectively from pre-existing knowledge that allow such individuals to experience a social practice. Justified to serve the collectives that develop a university extension work, especially in basic education. Contributes to the praxis of artists and writers with regard to reflect in his plays, his debates with the public after shows or even on how they look. The survey featured a documentary analysis, scripts, using content analysis as methodological procedure. Created two categories of analysis: social representations of science in both scripts. Divide into three subcategories: "science as absolute truth (sure) and/or transience (doubt)"; "the scientific field and the search for recognition"; and "the relationship between science and fantasy". And the second category, the social representations of the scientist in the two scripts of theater. We conclude that the word "truth", its synonyms or antonyms may not have a large occurrence in both scripts, however that doesn't stop to observe a social representation of science that is sometimes taken as absolute. There is also in its Constitution space for doubt, uncertainty, but accompanied by a sense of hierarchy. The success of an experiment, the formulation of a model or a production technology by any one of the characters leads to elevation of this to a prominent post inside the camp. Is a young scientist trying to impress your tutor or a renowned researcher trying to stand out in relation to their peers, the legitimacy on this is a goal, sometimes hidden, in both scripts. For their motivations, the authors build characters that act in order to generate id us bystanders and, for that, use their social representations. They have elements in common with the representations that the public has. One is that the scientist is differentiated from other people. Even without any mannerisms, the characters end up moving away, even though geographically in an isolated house.

    Os geopolímeros (polímeros inorgânicos) têm atraído a atenção da academia por várias razões, em particular pelo fato de ser considerado um material sustentável onde subprodutos industriais podem ser utilizados como matéria prima, além de um processo de baixo custo energético. Tais materiais encontram aplicações em todos os setores industriais, dependendo da razão atômica Si:Al, responsável por suas propriedades. Atualmente seu grande volume de aplicação está na substituição do cimento Portland. Entretanto, devido às suas propriedades similares aos materiais cerâmicos e a busca cada vez maior por novas aplicações, estudos sobre geopolímeros porosos tem despertado grande interesse da academia. Porém, as rotas usadas atualmente na obtenção dessa classe de materiais são baseadas nas da construção civil para a produção do concreto aerado, de porosidade fechada, limitando sua aplicação onde porosidade aberta é necessária. Neste sentido, este trabalho teve como objetivo o desenvolvimento de duas novas rotas de processamento (Gelcasting Route e Gelcasting/Saponification/Peroxide Combined Route), para a criação de uma nova classe de geopolímeros porosos com porosidade aberta. Em ambas as rotas foram adotadas a técnica de espumação direta para a produção de componentes cerâmicos, sendo que a maior diferença entre elas está na natureza química do agente porogênico. Na Gelcasting Route foram usados surfactantes comerciais, e na Gelcasting/Saponification/Peroxide Combined Route foi explorada a reação de saponificação de um triglicerídeo em meio alcalino para a geração in situ de surfactante. A partir das novas rotas foram produzidos geopolímeros altamente porosos, com microestrutura homogênea, células abertas e porosidade de até 85vol%, com propriedades físicas que sugerem sua utilização como substituto de baixo custo para produtos cerâmicos em aplicações tais como, suportes de catalisadores, filtração de gases quentes, adsorção e isolamento refratário de fornos.

    This research, of an interpretive and documentary nature, aims to analyze the reports that are produced by undergraduates of a Portuguese-Spanish Language Teaching Course, as a requirement for the subject Supervised Practicum in Foreign Language (observation and practice stages). The corpus of this study consists of reports written by undergraduates as part of the subject Supervised Practicum in Foreign Language of Portuguese-Spanish Language Teaching Courses in two universities in São Paulo State, a public one and a private one. The organization and analyses of data were done according to the analyses of categories (BURNS, 1999). As a theoretical background, we considered authors such as: Almeida Filho (1993; 1999; 2006; 2011); Alvares-Ortís (2006); Vieira-Abrahão (2001; 2002; 2006; 2007); Silva & Margonari (2005); Kfouri-Kaneoya (2003, 2008); Gileno (2013), among others. We assumed that the undergraduates of the Portuguese-Spanish Language Teaching Courses, when observing and teaching classes in regular schools, reflect on some aspects related to the language teaching/learning process (teacher, student, language skills, types of exercises, the content of classes, etc.) and describe their reflections and experiences in the reports they write by the end of the subject Supervised Practicum. Thus, by means of the reports written by the undergraduates, we sought the aspects that could support the following research questions: 1- What do undergraduates reveal in the reports they produce during the Supervised Practicum (observation and practice stages)? 2- Do the reports on the practice stage of Supervised Practicum indicate a consistent practice with the reflections made in the reports on the observation stage of Supervised Practicum? 3- Are there moments of theoretical and methodological reflection on the observation and the practice in the reports that relate to the studies of Applied Linguistics? When answering the research questions, despite consulting several theoretical texts, we noted in the reports that there are several problems in the stages of the Supervised Practicum that are not addressed in the publications consulted, such as the carelessness of some higher education institutions concerning the initial education of teachers and the difficulty of finding schools where the undergraduates are able to carry out the Supervised Practicum of some foreign languages, including Spanish. We also noticed that, depending on the institution, there are notable differences on how to conduct and record the Supervised Practicum stages, and that the expected reflection about the theoretical and methodological aspects, although not fully developed in all reports, can be perceived in some of them. Therefore, we tried to point out and justify the failures of the Supervised Practicum stages that we found in our corpus of research in order to contribute to the improvement in Supervised Practicum and hence to teacher education.

    This work has as its object of study the Programme For International Student Assessment (PISA), an international assessment system, created in 1997 by the Organization for Economic Co-operation and Development (OECD) and reaches fifteen students who are in final phase of compulsory schooling. The objective of this study is to analyze the PISA through its justification of creation, objectives and concepts that underlie the official documents of the OECD. In particular, through the analysis of conceptions of quality, equity and accountability in official documents of PISA, we seek to understand to what extent these conceptions are articulated with the economic development goals of OECD, as well as understand the participation of the Organization in educational policies, identify practices that the discourse of OECD seeks to engender in education management and how these conceptions allow to legitimate new forms of assessment which gradually reorganize and impose a new form to the educational process schooled. The theoretical-methodological approach is based on bibliographic and documentary research. The analysis will take place by means of the categories of discursive and social practices, by Paul Veyne, modernization and rationalization, by Max Weber, and the conceptions of social justice and equity, by John Rawls. Our analyzes showed that PISA is a producer and promoter of discursive practices, which aims to spread the instrumental rationality in education, standardize knowledge and skills required by the economic sphere, as well as homogenize and optimize the educational policies worldwide. Thus, PISA is more than an evaluation system, it is a global governance agent that, which through indications and discursive persuasion, kind of soft power actions made by the OECD and legitimized by the participating countries, seeks to disseminate best economic practices in order to homogenize the international productive sphere. Therefore, PISA is projected as an education regulation tool for economic and political purposes.

    The sea of real-time images, the instant access to latest news and the contemporary demand that praises and requires the so-called positive social values pass by the exhausting and brutalized affirmation process of this established culture. Television, in this regard, can become a powerful vehicle of ideology exchange, due to its global reach. However, television could be an education tool, provided that its content and form are properly prepared to this end. Following these discussions, and guided by readings of texts by Theodor W. Adorno and Herbert Marcuse, we propose the analysis of the content of educational television program, transmitted by television and Internet, Salto para o Futuro (Leap into the Future, in Portuguese), on TV Escola (Ministry of Education), as well as the observation of technical changes, in other words, the way the information are structured and transmitted by this mean of communication, born as a result of the digital technology emergence. Analysis has demonstrated that there is Form predominance over Content since the analyzed episode articulates its messages via TV newscast format, which beforehand tends to ensure spectators adhesion by its serious aspect. Another important aspect comes from the presence of a discursive pattern in the messages: the hero specialist teacher cliché who in the future, by magically jumping over the historical and material contradictions in the present days, will save education by using technology. Finally, we conclude that the general format of the Salto Para o Futuro TV show (Leap into the Future, in Portuguese) does not allow the offer for explanatory information. However, through the radical change of its dynamics - disruption of the formal hierarchy by dialectic relation tension of the Formation concept - the program could envision an educational horizon: an aid to reveal the mechanisms that prevent the refusal and resistance of what is presented as if it were real.

    Nanoporous anodic alumina films (NAA) may present different behavior to reflectance and photoluminescence techniques, with Fabry-Pérot interferences and waveguide properties. This phenomenon makes possible the use of NAA as transducer signal in optical sensors. In this work, we investigated how the pre-treatment, the number of steps of anodizing, the anodizing electrolyte mode and temperature affect electrochemical characteristics, morphological and optical mainly NAA. As a result, it was noticeable that the realization of electropolishing is necessary for both the NAA with good regularity as to make it possible to obtain a spectrum with the Fabry-Pérot interference. If the fabrication of NAA is done in two steps, it is possible to obtain reflectance spectra and luminescence fringed with better amplitudes, areas and heights. Regarding the anodizing mode, both the NAA anodized in galvanostatic how potentiostatic showed similar morphologies and spectra with fringes, but the interferences were better defined when the galvanostatic mode was performed. Regarding the temperature, it was noticeable that the change of this parameter leads influences the porous oxide thickness. The spectrum of the luminescence and reflectance increasing the electrolyte temperature caused an increase in interference. However, the range and resolution of interference decreased with increasing temperature. The oxide thicknesses were estimated by energy variation (?E), graph slope between order and 1/? and fast Fourier transform (FFT) techniques. The ratio of film thickness and pore diameter (L/dp) was performed to validate the NAA films with better waveguides property. Moreover, the surface composition analysis of NAA films anodized in phosphoric acid, oxalic acid and mixtures thereof by backscattering spectroscopy Rutherford (RBS) was performed. From simulations it was possible to note that the amount of carbon in the porous oxide structure is practically zero, which may indicate that the origin of the luminescence is related to the presence of more centers F.

    Six Sigma is an improvement program adopted by many companies to improve their business performance. However, some studies indicate that the relationship between Six Sigma and competitive advantage is not that clear. In this context, the main objective of this dissertation is to identify the relationship between the implementation factors of Six Sigma and competitive priorities in companies that operating in Brazil. As steps, this research conducted bibliometric analysis, content analysis, descriptive analysis and factor analysis. The research investigated 45 companies, through a survey, to find the relationship between Six Sigma implementation factors with competitive priorities in Brazil. Implantation factors identified were: "collect and availability of data", "previous infrastructure", "performance indicators", "goal setting", "capacity for change", "top management involvement" and "statistical thinking" . The results indicate the implementation factors that have relationship with competitive priorities are "collection and availability of data," "previous infrastructure" and "capacity for change". In addition to this result, it was found that the dimensions of competitive priorities that have relationship with implementation factors are "reliability" and "flexibility".

    Superconductivity one of the most intriguing physical phenomena has been extensively studied due to their potential for technological applications. Despite advances in research in physics there is still no complete theory to explain the phenomenon. We study the behavior of a superconducting system described by a multiband model. We consider the interband interaction, i.e., the interaction is between the fermions with dierent masses at dierent bands, under the inuence hybridization. Also, we study the intraband interaction with hybridization and external magnetic eld. Using the method of Green's functions of Zubarev, we calculate the superconducting order parameters with intra-and interbanda interaction at zero temperature, ie, T = 0, and for dierent temperatures of zero. Interband interaction obtained in the superconducting order parameter as a function of temperature and hybridization V. The phase diagram T versus V was also obtained. The superconducting properties, such as free energy, entropy and specic heat, were also determined in the intraband interaction. Initially, we calculate the superconducting properties in zero eld, ie, for H = 0, then we consider the presence of external magnetic eld H nonzero. obtained an implicit equation that relates the magnetic field, temperature and hybridization, which allowed us to obtain the phase diagram T versus T and T versus V . Our results show that both the hybridization V , as the external magnetic field H acts at the expense of superconductivity by suppressing it. We noticed also, and conrmed by other studies, that the intraband interaction, we have only second order transition, since the interaction interbanda, we obtained a superconducting tricritico point where we encounter a line first with a second order. Based on these results, we conclude that left a signicant contribution to research in superconductivity.

    Industrialization in the Brazilian construction industry is a growing trend, while the need to fulfill tight deadlines increases as well as labor costs, being mandatory to keep quality standards and the competitiveness of enterprises. In this sense, the precast concrete is an increasingly valid solution.Among him, the floor in hollow core slabs of prestressed concrete, as part of a constructive system of open cycle. This kind of floor can be applied in various sectors and to the most varied typologies. The ABNT NBR 14861: 2011 is still quite new, and includes a set of quality control care for the implementation of hollow core slabs in prestressed concrete, although it is felt that the respective degree of detail could be improved.On the other hand, the standard has just focusing on such care specially concerning project and product approaches, and not so much with a process approach. There is also some difficulty in the flow of information and knowledge between the academy and industry in general. The dissertation provides a detailed analysis of production of hollow core slabs in prestressed concrete, according to the respective processes, since the inputs enter factories, until the structural cover is performed on site. The macro-production process is divided into several stages of lower complexity, and contains a detailed listing of quality control procedures required, in a simple and practical manner. Thus, can be established a kind of a guide to good quality control practices for the production of LACP, which is then systematized through a set of checklists. The establishment of guidelines for good quality control practices in the various LACP production stages is the main goal of this research. In order to accomplish this goal have been made extensive literature reviews on Quality and hollow core slabs, using theses, dissertations, monographs, papers, magazines and electronic sites. Were also made visits to a factory which produces equipment for production of hollow core slabs, and to a plant producing LACP, in the interior of the state of São Paulo, during which were made unstructured interviews with their maximum management responsables. Finally it was made an essentially qualitative comparative analysis of the data collected and the quality control procedures of the ABNT NBR 14861: 2011. It is intended, with the checklists contained in the dissertation, to ensure production, transportation to site, installation of LACP and execution of the respective structural wrapper, with the highest quality consistency that is possible, thereby minimizing to minimum the existence of possible non-compliances.

    This thesis consisted of two studies described below. The Study 1 aimed to investigate if expiratory flow limitation (EFL) present at moderate intensity exercise in subjects following myocardial infarction (MI) (as shown in a previous study conducted in our laboratory) already manifests in those with stable coronary artery disease (CAD). Forty-one men aged 40-65 years were allocated into four different groups: 1) stable coronary artery disease (SCADG) (n=9), 2) recent myocardial infarction (RMIG) (n=8), 3) late myocardial infarction group (LMIG) (n=12), and 4) health control group (CG) (n=12). Two cardiopulmonary exercise testing (CPX) at constant workload (moderate and high intensity) were applied and EFL was evaluated by exercise flow-volume loops. We observed that during moderate intensity exercise the RMIG and LMIG presented with a significantly higher number of subjects with EFL compared to the CG, while no significant difference was observed among groups at high intensity exercise. Regarding the degree of expiratory flow limitation, the RMIG and LMIG showed significantly higher values at moderate intensity exercise when compared to the CG. At high intensity exercise, significantly higher values for the degree of expiratory flow limitation were observed only in the LMIG compared to the CG. We concluded that an EFL was only present in MI groups (recent and late) during moderate intensity exercise; whereas at high intensity exercise all groups presented EFL. Thus, EFL observed at moderate intensity exercise in both MI groups may be linked to the consequences of event and not to CAD. Following, the Study II aimed to investigate the indexes of circulatory (CP) and ventilatory power (VP) in CAD patients. Eighty-seven men were studied aged 40-65 years, being 42 subjects in the CAD group and 45 in the CG. CPX was performed on a treadmill and the following measures were obtained: 1) peak oxygen consumption (VO2), 2) peak heart rate (HR), 3) peak blood pressure (BP), 4) peak rate-pressure product (peak systolic BP x peak HR), 5) peak oxygen pulse = (peak VO2/peak HR), 6) the oxygen uptake efficiency (OUES), 7) the carbon dioxide production efficiency (VE/VCO2 slope), 8) CP (peak VO2 x peak systolic BP) and 9) VP (peak systolic BP/VE/VCO2 slope). The CAD group had significantly lower values for peak VO2, peak HR, peak systolic BP, peak rate-pressure product, peak oxygen pulse, the OUES, CP and VP and significantly higher values for peak diastolic BP and the VE/VCO2 slope compared to the CG. Furthermore, a stepwise regression analysis showed that CP was influenced by the group and VP was influenced both by group and by number of vessels with stenosis after treatment. Given the findings, we concluded that the indices of CP and VP were lower in men with CAD compared to CG. Thus, both studies brought important findings related to the responses of the cardiovascular, pulmonary and musculoskeletal systems of patients with CAD during physical exercise, bringing many contributions to clinical practice and assisting in the prescription of exercise training.
