The physical limitations of silicon forced the industry to develop solutions that exploit the processing power of combining several general purpose processors. Even complex supercomputers that have multiple processors, they are still considered to inefficient processes that require large amounts of arithmetic operations using floating point data. Reconfigurable computing is gaining more space to have a performance close to a specific purpose devices (ASIC), and yet keep the flexibility provided by the architecture of general purpose processors. However, the complexity of hardware description languages often becomes a problem to the development of new projects. Tools for high-level synthesis have become more popular, they allow the transformation code in high-level hardware simply and quickly. However, solutions found in current tools generate simple hardware that does not exploit the techniques to improve the pipeline in hardware. This paper presents the development of techniques to exploit processing parallelism of the reconfigurable devices through programs described in language C. These techniques identify loops and improve the performance in hardware. As a result, we have improved in the high-level synthesis process generating optimized hardware.

The family Pipridae is endemic to the Neotropics, having frugivorous habits. Males of some species make complex sexual displays to attract the females, and they live in the middle stratum of tropical forests. Of 51 species, 29 have their nests described, five have incubation periods descriptions, and six have nestling periods reported. The Blue Manakin, Chiroxiphia caudata, is common in humid and secondary forests of southeastern Brazil, northeastern Argentina and eastern Paraguay and its breeding biology is poorly documented. Here analyzed 36 active nests in two breeding seasons (2013/2014 and 2014/2015) in a well-preserved Brazilian Atlantic Forest continuum. Nests were swallow cups hung by their rims in horizontal forks, built in bushes or saplings, over or near forest streams. Reproductive activities were recorded from October to February and clutch sizes were invariably two eggs. Incubation period was 18 days, and nestling period was 15 - 16 days. Estimated overall nesting success, from egg-laying to fledging, was 40%, being higher than most studies on piprids that have been conducted in disturbed habitats. Our data give support to the theory that in the Pipridae family only females provide parental care.

With the process of financialization of the economy, companies are reorganizing themselves. In front of this, the present work has as main objective observe the process of financialization and its impact on the social structure of a company that went through the privatization process. Also, analyze in the corporate environment, (the new) forms of organizational management and production, as well its key actors and their forms of interrelationship. This work is based on Political Economics, with studies in the financialization process rooted in culture, history and policy of a company that has undergone in a series of transformations. This research develops how the company changes its conception of control, and how this change has an impact in its overall structure. Thus, the scope of this work focused on an exploratory study in Eletropaulo. The central importance of the study in the Brazilian electric sector is that this sector has undergone to the most radical changes in the financialization since 1990. However, any research on the built of the executive s careers, in this Brazilian context, has been done so far. The analysis of curriculum is the most important contribution from this case study research. As a research procedure of this work, were combined quantitative and qualitative methods. In order to analyze the careers of executives of AES Eletropaulo, were collected the curriculum of the Board and Directors, since its appearance as state-owned company in 1979 to the year 2012. It is applied a cumulative frequency analysis and other correspondence multiple analysis to study these curricula. Also, to see how the company was restructured as a whole after the change of ownership, were used other qualitative tools, such as questionnaires and interviews to key players in the buying and selling process. To develop this thesis, the case study will be separated into three parts. In the first are analyzed and presented data, in the form of graphs, related to the performance indicators of the company's case over his years before and after privatization. The second part is related to the new organizational management, which refers to the shareholding after the sale of the company, thus, opens up the discussion to the internationalization of ownership and National Development Bank in Brazil - BNDES, being the major shareholders of AES Eletropaulo an international company and BNDES. And in the third, the focus is on the analysis of the careers of executives of this company, and how they constructed and reconstructed their careers after major changes. As result, it was observed that the case company has undergone a series of transformations, including the creation of a new identity. The Government acts in two different moments at the same company. It is observed in this study that the pressure of these new owners have consequences in organizational design and composition of the power of the company to a search for maximization of the value of the company. And the executives of the company had to find ways to rebuild their careers in accordance with the new financial logic at the moment. The present analysis also extends to the electricity utility workers and their vulnerabilities occurred by the financialization process.

The process known as greening universities refers to the introduction of environmental issues in the teaching-research-extension and management fronts. Considering the various initiatives of the Federal University of São Carlos (UFSCar) insert the environmental education in the curricula and management, this study aimed to assess what form and how is this process in view of undergraduate students in chemistry and Pedagogy in three campuses UFSCar (São Carlos, Araras and Sorocaba). To this end, a virtual tool known as "Sustainability Test" was used (www.projetosustentabilidade.sc.usp.br) to assess sustainability practices in academic spaces. The themes analyzed in this study were divided in four categories: a) Environmental Management (waste management, water, energy, mobility / accessibility, green areas and green technologies); b) curriculum greening (environmental education in teaching / curriculum); c) Involvement and Participation d) The role of universities face to environmental issues. In addition to the questionnaire, interviews were conducted focus group type and consulted institutional legislation concerning the issue investigated. While acknowledging the Environmental Education (EE) in the institution, it was observed that most students of both courses were unaware of the actions related to environmental management, especially in the campus of San Carlos. The theme of "green technologies" still seemed far from the Education field, as well as the Science-Technology-Society-Environment Approach (CTSA). The main difficulty pointed out by students for their involvement in environmental issues is the lack of time and information, which may be a priority target given to the theme in these spaces. According to the data collected, the role of universities would be to invest in educational processes and disseminate scientific knowledge, approach the community, addressing EA critically. It was found that the promotion of reflection and dialogue between institutional subjects that carry different views on the greening of HEIs should be seen as necessary strategies to face the challenges inherent in such a process.

The thoughts and knowledge that individuals have about their own thoughts and cognitive processes correspond to metacognition. This concept has different aspects, but by focusing on the area of education, the skills involved in cognitive monitoring and self-regulation are the most relevant. Metacognitive skill assume that status because it allow the individual to assess their performance during the execution of tasks and if he conclue that it is not reaching the target set, he can change the strategies being used by more efficient ones. The use and mastery of skills to monitor and self-regulate cognitive activities are important for learning. Therefore, it is understood that the stimulation of such skills could be an alternative for achieving better academic performance. However, before stimulating, conducting assessment of metacognitive repertoire of students is required. The national literature demonstrated lacking in tools to measure child s metacognition and, in a previous study, the Metacognition Scale (EMETA) to assess these skills in children 9-12 years of age has been established. This study aimed to continue the analysis of the psychometric properties of the scale, more specifically to the analysis of evidence of validity based on the internal structure, the accuracy of the scale and the relationship with other variables such as gender, type of school, age and school year . It also investigated the correlation between performance in EMETA and Learning Strategies for Assessment Scale for Elementary Education (EAVAP-EF) and the grades in the subjects of Portuguese and Mathematics. Later, there was the confirmatory analysis to verify that the model found in the exploratory factor analysis fit the theoretical model used as the basis and preliminary standards for the scale to gender and age was elaborated. The results show that EMETA was composed of two factors, namely: a) Metacognition Knowledge b) Metacognitive Monitoring and Cognitive Strategies that explain 34% of the variance of the scale and precision of the 0,805. Statistically significant differences in performance was found for the variables gender, age and school year and the value for correlation between Metacognition Scale and EAVAP-EF was 0.48 considered good for instruments that measure similar constructs. Finally, participants with higher grades were also those who had higher scores on the scale.

Frailty is related to a decrease in the physiological reserves that causes a difficult to maintain homeostasis. The analysis of heart period (HP) and blood pressure (BP) variabilities can contribute to the understanding of cardiovascular homeostasis in the frailty syndrome. Objective: To compare HP and BP variabilities in frail, prefrail and nonfrail, un supine and orthostatic positions, by univariate and bivariate analysis. Methods: 39 elderly were evaluated and distributed in frail, prefrail and nonfrail groups, accordingly to frailty phenotype. The RR interval (RRi) and the systolic BP (SBP) series were registered for 15 minutes in the supine position and 15 minutes in orthostatic position. Univariate analysis (RRi: mean, variance, LFnu, HFabs and LF/HF and the SBP: mean, variance and LFabs) and bivariate analysis (phase, gain (α) and coherence (K2)) were performed. A two-way repeated measures ANOVA test was used for the statistical analysis; a 5% significance level was considered, along with group, position and interaction effects. Results: Univariate analysis do not detected changes in frailty syndrome. However, in the bivariate analysis frail presented lower K² than nonfrail in orthostatic position. Prefrail and frail reported a significant decrease in K² values in orthostatic position in comparison to the supine. Conclusion: Univariate analysis of HP and BP variabilities do not change when frailty syndrome is present. However, bivariate analysis indicated decoupling between HP and BP in frailty presence. Thus, a reduced K2 might be a marker of frailty process.

Biological invasion is a threat to biodiversity, due to competition for resources between invaders and native organisms, decreasing the overall biodiversity. So, studies about the invasiveness of the ecossystems and invasion potential of exotic plants several environments must be taken to control this species. Hedychium coronarium, from the Himalayas, is an example of a high invasivisiness plant, taken to different places in the world, mainly due to ornamental uses. This study evaluated the development (height, diameter, birth and ramets mortality and internal rhyzome anatomy) of plants under different moisture contents, in in situ and in vitro experiments. We found the existence of plasticity for both vegetative ramets growth, and the internal rhyzome anatomy, which may contribute to the invasive potential of this plant.

Magnesium oxide is an important subject of investigation because of its physical and chemical properties, mainly for its application to refractory ceramics. However, magnesium oxide hydration generates its hydroxide, Mg(OH)2, which may cause a volumetric expansion, possibly tightening and damaging components made from this material. These factors are limiting for the use in refractory castables and, as a result, most studies regarding this application is focused on minimizing its harmful effects. In order to minimize the effects of hydration on refractory compositions, this work evaluated two types of magnesia presenting different reactivity, caustic and sinter magnesia, with additives (CaCl2, MgCl2, CaF2, MgF2, acetic acid, magnesium acetate, citric acid and EDTA). The results indicated that the soluble salts (CaCl2 and MgCl2) accelerated the hydration, diminishing the apparent volumetric expansion, increasing the mechanical strength and the hydration heat. Because the addition of insoluble salts (CaF2, MgF2) promoted a reduction in the hydration degree, however, samples showed cracks, became crispy, and presented low mechanical strength. In the case of adding acetic acid or magnesium acetate, it occurred a precipitation acceleration of brucite, Mg (OH)2, as a result of the acetate ion complexation power generated, being mechanical resistance of the acetate greater than the acetic acid. The chelating agents (citric acid and EDTA) had distinct behaviors: the citric acid caused hydration decrease because of the absorption effect; and EDTA caused hydration increase as a result of its Mg2+ ions complexation power. It may be concluded that additives, presented in the compositions studied herein, are promising materials for refractory application, assuming that the additives hydrating will improve refractories mechanical strength, and those decreasing the hydration must be incorporated to other materials to improve their performance.

The significant increase in fish consumption in recent decades has led to considerable extractive exploitation that can bring harmful consequences to the environment and the community living the fishing sustainable exploitation. Therefore, it is essential the search for ways to mitigate this condition. The fish farming development appears as an alternative capable of contribute to the solution of this problem, since it would be possible to maintain the social demand for fish. In a strategic way, the exercise have been standing out by the effects produced directly on animal physiology. On fish, there is sustained evidence that swimming practices brings improvements in hematological parameters, in the metabolic profile of the animals and that may lead them to have great benefits into health and well-being. In study was evaluated the hematological and metabolic parameters and antioxidant response of Brycon amazonicus under control or not of sustained swimming and submitted or not to nitrite excess stress. Currently a major problem in recirculation systems face in fish farming in their biological filters.The submitted animals to sustained swimming activity had an attenuation indicative metabolic adjustment on the stress caused by nitrite. The animals on sustained swimming effects optimizes the carbohydrates oxidation aiming the energy production, thereby minimizing amino acids oxidation for this purpose. Similarly, the fish that were submitted to sustained swimming had produced reduced FOX values, indicating that this swimming activity can be a great tool against oxidative stress. In conclusion, Matrinxãs adapted to sustained swimming have a better ability to face oxidative stress caused by environmental nitrite, making changes hematological, biochemical and metabolism, which can improve oxidative metabolic processes.

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.
