The value of the circumference s length divided by its diameter has a result a constant named PI; This value is known since ancient times by the Greeks and Egyptians, but only in current history this constant has been recognized as an irrational number. This study has as objective to explore the relationship of the circle by II elementary school students and extension of numerical sets from this constant. Making sense of this value by checking its regularity in all circles through practical experiments and also exploring the technological resources available in the school, making the students to follow the steps for determining of the numerical value and to participate in the construction and discovery process of new knowledge. The teaching sequence proposed was based on Engineering teaching as research methodology, conducting in the end a posteriori analysis which demonstrates that learning from manipulable objects, together with technological resources available provides to students with a greater assimilation of mathematical content, one becoming a remarkable experience for elementary school students and being an important tool which complements the lessons and makes them more participative. It is hoped that this work support math teachers to reflect the usage of manipulative materials, educational software and all available resources which provide greater assimilation and approach the student with the mathematical concepts.

This work describes the study of natural compounds as potential bactericides for control of Xylella fastidiosa which causes the Citrus Variegated Chlorosis (CVC), a disease that causes large losses in brazilian citrus and still does not have a bactericidal specific in the market to combat it. The project was deveped in two stages. The first part of the work was done in vitro, where the compounds naringenina complexed with rutênio and magnésio, separately, hesperidina complexed with magnésio, azadirachtina, hesperidina and naringenina were tested as inhibitors of Xylella fastidiosa growth using the system of microdilution in culture media to detect the minimal inhibitory concetration of these compounds against the bacterium Xylella fastidiosa. These compounds showed, respectively, minimum inhibitory concentrations of 0,19 µM, 0,34 µM, 1,01 µM, 2,1 µM, 3,27 µM e 7,3 µM. In a second phase, the best results obtained in vitro were validated in Vivo experiments, where the bacterium was inoculated into healthy citros plants. After a period of manifestation of disease in plants, these were diagnosed by PCR analysis to identify which plants had been contaminated by the bacterial. After detecting diseased plants through the presence of Xylella fastidiosa s DNA, they were treated with those natural componds and their derivatives that have been tested in vitro. After a period of treatement, the plants to obsorb the metabolites and acted upon these bacteria, a analysis was perfomed by quantitative PCR (qPCR) comparing the amount of bacteria in plants before and after treatment with the bactericide, evaluating the occurrence or not, of the bacterium inibition. The following results were obtained: for naringenina complexed with Mg, 0,8 µM; naringenina complexed with Ru, 1,2 µM; azadirachtina, 1,4 µM; hesperidina, 1,8 µM; naringenina 3,9 µM and cuprum (positive control), 6,3 µM, this for 0,1% of life bacteria. The in vitro results consistent with the results in vivo.

The nucleus of the solitary tract (NTS) is the primary synaptic site of the peripheral baroreceptors and chemoreceptors. It has been shown that acetylcholine (ACh) microinjected into the NTS of rats induces hypotension and bradycardia. However, the contribution of cholinergic mechanisms at different NTS subnuclei (intermediate and commissural) as well as the cholinergic receptors blockade on the control of sympathetic (SNA) and phrenic (PNA) nerve activities have not been studied yet. In this study we assessed the role of ACh and its cholinergic receptors at the intermediate NTS (iNTS) and commissural NTS (cNTS) on the control of SNA, PNA and electrophysiological properties of these subnuclei neurons, as well as on baro and chemoreflex responses. Decorticated arterially-perfused in situ preparations of male juvenile rats were used to record SNA and PNA. Microinjections of ACh and cholinergic antagonists were performed into the iNTS or cNTS. Coronal slices of the brainstem containing either cNTS or iNTS subnuclei were obtained from male juvenile rats and used in whole cell patch clamp – current clamp recordings. It was observed that ACh microinjected into the iNTS inhibited both SNA and PNA. These effects were reduced by the pre-treatment with atropine (muscarinic antagonist) or mecamylamine (nicotinic antagonist). The cholinergic antagonists into the iNTS did not change the effects on SNA and PNA induced by baro and chemoreflex activation. In contrast, microinjections of ACh into the cNTS did not induce changes in SNA, but increased PNA. Despite the absence of changes in SNA, ACh into the cNTS changed the pattern of respiratory-sympathetic coupling. Both atropine and mecamylamine into the cNTS inhibited the ACh-induced tachypnea, but only mecamylamine inhibited the chemoreflex-induced tachypnea and the ACh-induced change in respiratory-sympathetic coupling. In vitro studies demonstrated that ACh promotes depolarization in both iNTS and cNTS neurons. Both muscarinic and nicotinic antagonism in the iNTS inhibited the ACh-induced depolarization. However, only nicotinic antagonist was effective in diminishing this response in the cNTS. The results suggest that ACh plays an important role in the control of cardiovascular and respiratory activities, with distinct functions between iNTS and cNTS. This cholinergic control involves activation of both muscarinic and nicotinic receptors within NTS, but only nicotinic receptors are involved in the chemoreflex tachypneic response.

The builders are looking to adopt measures to remain profitable due to increasing market competition. These measures involve not only the improvement of the production process, as well as meeting the needs and requirements of customers. The customization has been used to adapt the residential property to customer needs, thus improving the performance of the built environment and the value of the product. One of the reasons why the implementation of personalization on the world stage was increased socioeconomic pattern of the population which is now able to meet individualized expectations, being stimulated also by the tendency to customize, present in other sectors of the economy. However due to lack of planning and an effective system of communication and information management aimed at adoption of customization, there are delays and rework for the completion of construction stages. Lean Construction emerges as a methodology of workflows that aims to reduce non-value added activities. This study aimed to determine what types of customization are offered, which principles of the Lean Construction are applied and the information flow in building companies of residential buildings that offer customization to customers. As research methodology were conducted four case studies with the use of questionnaires and interviews that allowed the observation of the types of customization offered by the companies studied and the principles of Lean Construction that are being applied. Similarly, it was possible to answer the research question of how the internal processes of these companies that offer customization of residential properties are organized, outlining flowcharts of each company, that show the communication between the involved, from the sale of the property to the client to the delivery of materials required for execution of the work and customizations, and propose a template flowchart.

The Onion-tree is an efficient metric access method based on main memory for similarity search. The Onion-tree has already provided algorithms for insertion and processing of similarity queries (range query and k-nearest neighbors query). However, in the literature no algorithm has been proposed for removing elements in Onion-tree. For this index be incorporated into a database management system, it is necessary the proposal and implementation of at least one algorithm of deletion. This master's research focused primarily on the implementation and performance evaluation of the algorithms proposed for logical deletion in (CARÉLO et al., 2011). The proposal presented in (CARÉLO et al., 2011) led to the implementation of three algorithms, called LogicalDelete, ReplaceReducing and ReplaceGrowing. The first algorithm applies the logic deletion, while the other two algorithms are specializations adding special treatment for the deletion of elements in internal nodes with children exclusively leaf. The ReplaceReducing algorithm allows the reduction of the radius of the node that contains de deleted element. On the other hand, the ReplaceGrowing algorithm allows increasing this radius. In addition, algorithms have been proposed and evaluated for physical deletion that can be applied at any level of the Onion-tree. The algorithm ReorgAll rearranges all the elements in the hierarchy of the node that contains de deleted element, by physically removing the elements and reinserting them using the insertion algorithm, and algorithm PromoteNode, which extends the algorithm ReorgAll, promotes, when exists conditions for such operation, other node to replace the one that contains the deleted element. Experimental evaluation of the algorithms LogicalDelete, ReplaceReducing and ReplaceGrowing showed that the algorithm LogicalDelete is more cost effective than the algorithms ReplaceReducing and ReplaceGrowing in query processing after the deletion of elements. Experimental evaluation of physical removal algorithms showed that the promotion of a node to replace the removed node has advantages over the simple reorganization of the hierarchy of the node that contains the deleted element. Besides presenting lower cost of deletion of elements, the algorithm PromoteNode also outperformed the algorithm ReorgAll in query processing after removing elements. When compared with the logic deletion algorithm, for a large amount of deletion operations, the algorithms ReorgAll and PromoteNode produced performance gain of 21.6% in range query processing. However, in the same comparison, these algorithms have a much higher cost of deletion.

In this work we present some applications of graph theory in problems involving polynomial identities for the algebra Mn (K). A brief presentation of PI-theory and some concepts of graph theory, such as the definition of Eulerian graphs, which are the basic elements of this work, were presented to make the text self- contained. We show two different proofs of the Amitsur-Levitzki theorem, the proof of Razmyslov and other due to Swan's theorem - an important result on Eulerian graphs. Finally, a similar result of the Amitsur-Levitzki's theorem for skew-symmetric matrices is proved using elements of graph theory. We emphasize that the understanding of the technique makes it possible to simplify many results and has been an important tool in the study of PI-algebras.

Software systems are considered legacy when they were developed many years ago with outdated technologies and their maintenance process consumes a large amount of resources. One cause of these problems is the inadequate modularization of its crosscutting concerns. In this situation, an alternative is to modernize the system with a new language to provide better support for concern modularization. ADM (Architecture-Driven Modernization) is an OMG model-driven proposal to modernize legacy systems and consist of a set of metamodels in which the main metamodel is KDM (Knowledge Discovery Metamodel), which allows to represent all the characteristics of a system. The modernization process begins with reverse engineering to represent the legacy system in a KDM model. Thereafter, refactorings can be applied to the model and then generate the modernized code. However, the current proposals do not support crosscutting concerns modularization. This occurs because the first step is to identify the elements which contribute with the implementation of a particular concern and it is not supplied by ADM. In this sense, this dissertation presents an approach for mining crosscutting concerns in KDM models, thus establishing the first step towards to a Concern-Driven modernization. The approach is a combination of two techniques, a concern library and a modified K-means clustering algorithm, which comprises four steps where the input is a KDM model and the result is the same KDM model with annotated concerns and some log files. In addition, we developed an Eclipse plugin called CCKDM to implement the approach. An evaluation was performed involving three software systems. The results show that for systems using APIs to implement their concerns the developed technique is an effective method for identifying them, achieving good values of precision and recall.

Considering the changes in Brazilian education, consolidated from educational reforms promoted by the Federal Government in mid of 1990, attending the determinations made explicit in the documents produced by the World Conference on Education for All and the Report to UNESCO of the International Commission on Education for the Twenty-first Century (Delors Report) that propose to achieve an education that meets the demands of the contemporary world through the pedagogy of learning to learn also known as Pedagogical Competence, the writing in question discusses how these issues are spread in the project The Cinema Goes to School - the use of cinematographic language in education that integrate series of actions proposed by the Sao Paulo State Board of Education from the implementation of State Official Curriculum in 2008. The Educational Project referred, aimed at secondary school students from public schools, search in synthesis, promote by displaying several cinematographic productions the development of competences and skills, particularly the reader and the writer, from the perspective of providing an education that promotes the resources cognitive mobilization necessary knowledge to attend social demands, aiming the changes in the contemporary world. The research was made in several stages and involved the review of existing bibliography, application of questionnaires and semi-structured interviews with the pedagogical coordinators teachers and high school teachers from public schools located in the city of Sorocaba / SP. Moreover, it was made the tab data of on-line research made by SEE / SP on the application of the educational project in schools. Although teachers have the concern to meet the curriculum proposed by the SEE / SP particularly through the contents contained in the Book of the Teacher / Student, does it almost innocent, considering his lack of knowledge about the current educational policy both national and state even considering indispensable the content fulfillment presented in educational materials provided by SEE / SP aiming to be fundamental to provides the students with knowledge that will enable their entry into the labor market as well as in higher education.

Universities go through constant physical expansion processes, which requires planning, design and investment in infrastructure. Public universities often maintain their own design offices and teams responsible for planning and management of physical space, as well as for the supervision of building processes and others, which have a relation to society. This research aims to study and characterize design process and physical space planning and management inside public universities, through the systematization of processes and of internal flows of activities and information and, also, by identifying the key problems within these processes, as well as the relations between such processes and institutional planning instruments such as Urban Master Plans and Institutional Development Plans. The work presents a literature review and case studies of three Brazilian public universities, focusing its planning and design offices. As its main results, we present a diagnosis of the maturity stage of planning and management of the built environment processes within those institutions, characterize best practices related to those processes and propose some guidelines for project development in public universities.

The present research focuses on the question of memory and representation of the Brazilian civil-military dictatorship through the analysis of two films, Pra Frente Brasil (1982) [Go further Brazil] and Ação Entre Amigos [Action between friends] (1998), which explore this period of national history. Our goal was to understand the contributions and limits of these two pieces of cinematographic work as bearers of civil military dictatorship memories. So, we examine how the civil-military dictatorship comes to the scene in the mentioned pictures, relating them to their own production context. We take as presupposition the fact that films are bearers of meanings that allow us to understand the relation between human beings and their historical time. For that we take as our own the Pilar Calveiros s conception of memory and, trying to comprehend the relation between cinema, memory and society, we found our theory on Walter Benjamin s theoretical and methodological referential, as on his conception of History. This author proposes, by the way, that we may think on the cinema s political function. To investigate the relation between art work and society we use Tania Pelegrini s concept of refraction and the Pierre Sorlin s conception of representation. At last, we found on the trauma and resentment concepts, willing to comprehend how cinema represents the relation between the dictatorial past with the present.

This paper presents a practical math approach to everyday math student through the measures used in the football field do teach analytical geometry to students from public high schools. The activities were developed in E. E. Nelson Fernandes, in the city of Santa Rita do Passa Quatro, where the autor of the study has taught for 20 years and it was found that there is a mechanization of using standard formulas and still lack connection between this issue and the reality of the student. Football is a very common issue on a daily basis for most of the students of this school, and also a joke among some students and teachers, so a theme motivating learning any math related to it, such as distance between two players positioned on the field, equation of the when a player passes the ball to another, or when kicks the goal, what exactly are the basic issues of analytic geometry of the 3rd grade of high school. The work was done through a football field in reduced size using toy players without necessarily knowing the rules of the game, the idea is that students can visualize distances and even measure to check them. Through a sequence os activities, starting from the concept of distance between two points, gradually lead the student to understand the basic concepts of analytic geometry. One of the main results and related to this project was the participatory learning of students in building their knowledge through experimentation and visualization of concrete linked to the intellectual. The material reached this goal. This work has brought to this author a great professional development since the choice of the theme, its application in the classroom and finally the reflection of everything that has been done and what is recorded in this dissertation.

Hydrogen is considered a clean and versatile energy vector that can be used for many applications, having water as the major product of combustion, it a great potential to be an alternative to fossil fuels. However, the challenge for the establishment of hydrogen technology to be used widely and safely is hydrogen storage. In this work, it was studied the preparation of composites and nanocomposites using the polyaniline (Pani) as polymer matrix in order to obtain a new material for hydrogen storage. In situ Pani/Titanium dioxide (TiO2) nanocomposites with 10 or 30 wt% of TiO2 were prepared using two dopants: hydrochloric acid and docecylbenzenesulfonic acid (DBSA). Both polyaniline and TiO2 were synthesized. Pani/sodium alanate (NaAlH4) composites with 30 or 50wt% of NaAlH4 were prepared from dispersions in toluene. These composites were also doped with 2 mole% of TiO2 in order to decrease the sorption temperature of hydrogen. Two drying processes were studied: Spray Drying process and filtration followed by drying in a vacuum oven. Morphological characterization of the composites and nanocomposites showed a good dispersion of the filler in the polymeric matrix, in addition, microspheres of NaAlH4 encapsulated by Pani were obtained using the spray dryer process. Hydrogen sorption analyses were carried out for pure Pani-DBSA and for the composites with 50wt% of sodium alanate and 2 mole% of TiO2 obtained for the two different drying processes. From these analyses, the composites showed sorption of 0.60% H2, higher than that obtained for the pure polymer (0.42%). These results show evidence that the proposed composites may be used for hydrogen storage.

Monographic study, historical interpretation in the area of philosophy of education. In True Method of Studying, Luis Antonio Verney openly criticizes the education provided by the Jesuits, blaming them for all cultural and educational backwardness of the Kingdom. Grounded in modern philosophy, Verney, proposes a reform at all levels of educational Portugal - primary, secondary and higher education - formulating a new ideology of education for the state. Based on empiricism, which started from the observation and experience, contrasted to the formal logic of the deductive method of the scholastics, foundation of Ratio Studiorum of the Jesuits. His criticisms and proposals influenced the creation of the first secular educational system in Portugal, after the expulsion of the Jesuits in the reforms of Pombal. While that seems to have disrupted with the scholastic model by proposing empiricism, his enlightenment was conservative, not revolutionary, Catholic, because he always defended the maintenance of (the) faith , fidelity to the Church, conciliation between faith and reason , which are the foundations of scholasticism. In this work, the following questions are raised: What were the main characteristics of the Enlightenment of Portuguese pedagogy? Did Verney disrupt scholasticism? Or just added some ideas of modern philosophy, maintaining the essence of that current of thought? This work seeks to understand how the creation of Portuguese public education occurred, and thus better understand, too, the Brazilian education. Bibliographical monography based upon the historical-critical methodology. We conclude that Verney disrupted scholasticism partially, by proposing a new method based on empiricism of Locke and blaming the Jesuit educational model for the delay of the kingdom, but at the same time kept as Portuguese priest the ideology of the Catholic faith, and, because of that he created a new Portuguese scholastic. He brought major contributions to the educational reform in the kingdom such as the appreciation of the Portuguese to the Latin, the secularization of the educational system, the education of women, literacy for all subjects, the creation of a new academic education based on the appreciation of the experience, among others.

Arbitrary stimuli can be related through conditional discrimination, via procedure Matching-tosample. The procedure can also establish equivalent relations emerge when relations were not directly taught. Such relationships must share three properties: reflexivity, symmetry and transitivity. Authors propose that success in establishing stimulus classes stems from the possibility of appointment by the participant. Among the possibilities to define "name", two stand out in this work: as Tact, towards an object in the environment the person issues an oral word; or as a higher order behavioral relation and bidirectional combining conventional functions of speech and listener. Taking into account the studies presented by both proposals, there appears to be evidence to prove that the appointment is necessary for the establishment of equivalence classes. Therefore, it is important to study participants who have incipient verbal repertoire to test the relationships of verbal behavior in the establishment of conditional discriminations and arbitrary stimulus classes. This study aims to determine the relationship between the verbal repertoire and the acquisition of conditional discriminations in babies up to 30 months old. This was done / assessments will be carried language development of participants through the Denver II and Operational Portage Inventory. Five teaching conditional discrimination procedures and tests of naming and equivalence were conducted with thirteen participants from 13 to 28 months. The verbal repertoire of these participants were classified according to the Skinner s taxonomy, and were also recorded behaviors listener and follow rules during teaching sessions and moments of free play. As a result, it was observed that all babies emitted echoic, tact and mands during session, eight participants learned the conditional discrimination proposals, all they learned discrimination vocalized the names of the experimental stimuli at some point, five participants underwent tests of symmetry and transitivity with familiar stimuli, two participants tested, none passed tests of equivalence. This indicates that the conditional discrimination learning depends on methodological aspects employees; verbal behavior, including the appointment of the names used in teaching auditoryvisual discrimination, can facilitate this learning. However, there is still no conclusive data on the need of the ability of appointment to the establishment of equivalence classes of stimuli.

The objective, in this paper, is to investigate the enunciative plans formation in narrative texts productions written in native language (Portuguese) from elementary school students II, 3rd and 4th cycles. In this approach, the research s central objective lies in the observation of enunciative plans confluence competing in the same text. When the students tried to reproduce the models, which the school works with, they rehearse to assume the place of subject, judging the narrated facts.To discuss this matter, we take for observation the subject marks, space and time generated by the lexical-grammatical relationships and constitutive implications of enunciative plans. Although one cannot say that these occurrences are characterized as errors, one also cannot say that these enunciation changes cannot generate disconnected texts. Therefore, it negatively influences the evaluations of school activities. Taking The Theory of Predicative and Enunciative Operations by Antoine Culioli as a theoretical axis, that favors the enunciative situation in the language constitution, we seek the linguistic marks and modal expressions in the statements that denunciate these different structures. The modal expressions lend us clues of enunciative operations activated by the subject, constituting the mode to enunciate from the enunciator subject. We propose that the teacher can lead the student to the knowledge of his/her own production process and work in the development of the student's discursive capacity based on the theoretical framework we adopted. However, the enunciative mechanisms that constitute the statements and generate the language process need to be known. We used as a standard in the analysis process: the determination marks and indeterminacy of the parameters of subject, space and time; the functioning of the statements by the discret, dense and compact typology, the notions that involve the weights of quantification and qualification. These transactions, analyzed together, enable us to determine the different enunciative plans. In other words, the History enunciative plan and the Speech plan, which correspond in the activities we work with, respectively, to the narrative and dissertative/argumentative texts.

Much has been written about Worker's Party in the literature, which discusses basic and general topics such as the party's foundation, to a more specific ones, such as government experiences and national power achievement. Nevertheless, although Worker's Party is a very well-known subject in political science literature, there are still a few theoretical gaps regarding two main dimensions: cultural and regional; especially when addressed together. Based on that, this study is developed in order to explore one of these gaps, which aims to analyse the political culture of the PT leaders from Paraná state by means of a comparative table, with people responsible to the meetings and conferences. The reason for focusing on Paraná state was the particularities found in terms of party's formation processes, which strongly influence the actions and structure of the party along its agency according to Panebianco. However, it is known that such particularities are due to historical context and economic development of the state which determine the formation of specific groups, and consequently the PT-PR group. As a result, it was found that mobilized sectors in Paraná have different characteristics in comparison to the most recognisable experiences such as those of ABC. In summary, we argue that these different factors tend to influence and create some particularities with regards political culture of these leaders.
