    The main objective of this study focuses on the identification and analysis of expenditure incurred by rural and urban schools of Paraná with a view to calculating the cost-student, through the analysis of public policies implemented in Brazil and financing in the State of Paraná. We decided to make a documentary research, employing a quantitative and qualitative analysis of the brazilian legislation, contained in their constitutions and expressed by a set of policies that govern and regulate the educational field in our country, in particular its financing. The universe involving our research focused on five rural schools from Arapongas twelve urban schools that accept students from rural and twenty-four urban schools serving children and adolescents in the city of Apucarana. We note that the cost-student for the two schools goes far beyond the minimum set by the Brazilian federal government value, as well as specified by the Paraná state government, on average exceeding them up to four times the minimum value. We understand that the use of accounting, its resources and its instruments used both for display and for the analysis of legislation and public policies that regulate, standardize and manage the brazilian educational field can contribute to improving the school realities of individuals living and work in the field.

    The purpose of this research is to understand the formative process developed in a group of mathematics teachers guided in the use of computers inclusion in their pedagogical practices. The question that guided the development of the research was: What are characteristics emerge from the formative process in a collaborative group of mathematics teachers to use computers in their teaching? This research is qualitative, of type participant observation. The data collection was carried out face of meetings a collaborative group of math study entitled Collaborative Study in Mathematics Education Group (CSMEG). Discussions of audio recorded meetings were used; oral and written narratives on the teaching practice; activity of scripts built out from the work proposal with the use of information technology and e-mails from the group on the profile and individual graduation and the sharing activities. For the analysis, we used the theoretical reference on teacher education, especially on reflective practice, collaborative groups and information technology in mathematics teaching. The reading of the data allowed to establish a guiding axis that highlights aspects of content and reflexive dynamics found both in the preparation of mathematical activities and in developing classroom environments with computer technology. From the discussion of the shaft were constructed three categories of analysis: 1. The computer technology insertion on collaborative group; 2. The computer technology insertion on mathematics education; and 3 Reflective practices on collaborative group. The results indicate that the pedagogical practice needs to be the starting point of reflective learning process, as shown in the proposed content and collective choices of the group during construction activities. The computer technology insertion's potentiality of visualizing and development of activities help on exploiting and relations of mathematical concepts. The elaboration of activities with the use of computer technology directed to individual interests contribute to the redefinition of the mathematical concepts and knowledge of the practice. Moreover, the reflective discussions that permeated the elaborations of the activities with the use of computer helped the teachers analyze and build meaningful activities with a look at content, to the student and to their knowledge.

    Between 2001 and 2011, the significant reduction in the homicide rate in São Paulo has sparked controversy in public debate and social sciences. What causalities certainly multiple, and analytic assumptions that explain this phenomenon, a São Paulo specificity in the national framework? In 2001 the city of Luzia to be studied here, located in the Metropolitan Region of São Paulo (RMSP), presented homicide rate of 51.57 / 100 000 inhabitants; in 2010 this rate dropped to 5.53 / 100,000 inhabitants, a tenth of the initial value. However, in 2011, further significant increase to 18.11 / 100,000 inhabitants in the city, has blurred the picture even more complex. The objective of this research is to study the truth discourses around litigation and homicides operating in an intersection zone, expanding, between state and local policy in relations between broken and chain. The listed data are based on a living as a resident in the city for over 20 years, and of practice in local organizations, over the 2000s, now recovered in the light of ethnography in the territory, conducted between 2012 and 2013.

    From 2010, Brazil ranks as the largest consumer of pesticides in the world, being 99% or more of sprayed pesticides can disseminate to the environment, and consequently reaching the ground and water. A possibility attempt to remedy this contamination is the use of Advanced Oxidation Processes (AOP). These processes consist in formation of highly oxidizing species in a way to mineralize organic molecules. The species can be generated from photoactivation reactions using a semiconductor under ultraviolet-visible radiation. A promising and underexplored semiconductor in catalysis is Nb2O5 which presents notable chemical and physical properties also, niobium is highly available in Brazil and present low cost. This work aimed to evaluate the use of an abundant material in Brazil, niobium, in order to contribute to the resolution of an environmental problem and public health, the water contamination by pesticides. In this way, it tried to draw parallels between the structural, morphological and surface characteristics of the synthesized Nb2O5, and its photocatalytic activity against pesticides. Nb2O5 was synthesized by three different methods, Polymeric Precursors, Hydrothermic and Decomposition. The process was optimized for each method varying different parameters in the employed methodology. The techniques X-ray diffraction (XRD), Scanning Electron Microscopy with Field Emission Gun (SEM-FEG), Zeta Potential, Infrared, Diffuse Reflectance and Raman spectroscopies; were used to characterize the synthesized materials. The photodegradation process under UVC radiation (254 nm) was monitored using UV-spectroscopy in the UV-visible region and its efficiency was evaluated by means of kinetic study. In general, it was found that the polymeric precursors method produces the most efficient Nb2O5 photocatalyst. Thus, this method was used for impregnating the previously synthesized magnetic nanoparticles (magnesium and cobalt ferrites) with Nb2O5, in order to remove the photocatalyst from water and enable to reuse this material. From the obtained results it was observed that the magnetic nanoparticles do not influence the photocatalytic response and may provide the removal and reuse of the photocatalyst.

    The Federal Law 11.947 of 2009 provides that states and municipalities, to perform actions of the National School Feeding Programme (PNAE), must spend at least 30% of funds received from the National Fund for the Development of Education (ENDF) to purchase products from family farms. Despite presenting innovative features, such regulation has many challenges. Highlights the need for greater contact and cooperation between government managers and farmers during the PNAE implementation process. The literature that addresses the concept of innovation in the public sector also indicates the importance of inclusion of citizens/users in the design and provision of public actions. Based on these, this research aimed to identify innovative aspects in the PNAE implementation process in Sorocaba-SP. Also aimed to raise inducing aspects and barriers to innovation in this process. Collection and analysis of data, we used a qualitative approach and the method of single case study with multiple units of analysis and multiple sources of data collection. Among the main results, it was found that the participation of the actors involved in PNAE presented two different times as to the pricing of foodstuffs, impacting the relationship between the municipal government and the cooperatives of farmers. In general, there is no communication between the two main public sectors involved in the implementation of PNAE. By the family organizations, the formation of a central cooperative allowed greater representation of individual cooperatives. As inducing factors for the adoption of innovative practices, we highlight the own federal regulation - which gave rise to the need for inclusion of cooperatives in school food - and social pressure held in the spaces created through discussion forums and public hearings. Among the main barriers, were identified the legacy of past practices resulting from the outsourcing process, the lack of social control and lack of participation by the Council of School Feeding (CAE), besides the lack of public infrastructure geared specifically to meet agricultural and supply issues in the municipality.

    This study examines the career of Federal Police special agents in São Paulo, in order to observe how concepts like masculinity, gender and difference are articulated to professionalism by them. This study conceives gender as something that is constructed, and often reproduced when such agents experiences the profession. Thus, it is necessary to explore the existence of an institutional hegemonic masculinity, as female and male, gender are made and how the pattern of heteronormativity are experienced in every day pratice in this career. The field research was conducted in the city of São Paulo. The methodology is based on qualitative interviews and analysis of documents from the Federal Police, as well as statistical data of the gender composition of the group, these empirical evidences are focused by the approaches of sociology of professions.

    The goal of this dissertation is to discuss the two main theoretical sources that Jürgen Habermas uses in his essay "Work and Interaction": the Hegel s philosophy of Spirit of Jena period (1804-1806) and the Marx s theory, especially the labor category. In this sense, beyond criticism resumption of primary sources, the study also presents alternative perspectives to those assumed by Habermas in his youth period, mainly in the 1960s. Therefore, a critique of young Habermas' theory becomes possible, from the central concept of the public sphere to the reasoning of cultural formation in the private sphere, this being the focal point of the essay in question.

    Tumor spreading occurs mainly by two pathways: through blood vessels and by lymphatic vessels, but the last is preferred by breast tumor cells. Some proteins are involved in cell adhesion and proteolysis, causing metastasis, such as ADAMs, a family of multi-domain and multi- functional proteins that contribute in these processes. ADAM9, a member of this family, has been increased in a large number of human carcinomas, including, breast cancer. In this context, the aim of this study was to evaluate the role of ADAM9 in tumor spreading via blood and lymphatic systems, in the search for new targets and focusing the development of new therapeutical tools. Therefore, MDA-MB-231 breast tumor cells were silenced for ADAM9 and tested with respect to their adhesive and invasive activity against blood and lymphatic endothelium. Our results showed that ADAM9 silencing in MDA-MB-231 breast cancer cells inhibited the invasion of this cells in matrigel (71.51 ± 8.02%) when compared to control cells, without affecting cell adhesion, proliferation, migration, and gene expression of the ADAM10, ADAM12, ADAM-17, cMyc, MMP9, VEGF-A, VEGF-C, Osteopontin and Collagen XVII, however, there was a decrease in the expression of the ADAM15 and increased expression of MMP2 when compared to controls. Furthermore, ADAM9 silencing did not affect the adhesion under flow to these vascular endothelial cells (HMEC-1 and HUVEC) and lymphatic (HMVEC-dLyNeo-Der). However, there was a decrease in the rate of trans-endothelial migration through the monolayer endothelial cells (HUVEC, HMEC-1 and HMVEC-dLyNeo-Der) by approximately 50%, 40% and 32%, respectively. In conclusion, ADAM9 showed to be essential in invasion and extravasation of MDA-MB-231 breast cancer cells through the blood and lymphatic vessels in vitro.

    The Steam reforming of Acetone (SRA) reaction was studied on magnesium aluminate (MgAl2O4) supported nickel (Ni) and cobalt (Co) catalysts. The catalysts with 8 wt.% of Ni, Co or Ni-Co were prepared by dry impregnation and characterized with X-Ray Diffraction (XRD), Temperature Programmed Reduction (TPR) and Thermogravimetric Analysis (TGA). The catalytic tests were carried out at the molar ratio H2O/C3H6O = 6 of three ways: i) Thermal decomposition of C3H6O as a function of temperature between 523 and 973K; ii) SRA reaction as a function of temperature between 523 and 873K; and iii) SRA reaction in presence of H2 as a function of temperature. The stability tests were carried out for 4 hours at 773 and 4 hours at 873K. The thermal decomposition of acetone in homogeneous phase was significant above 923K. The SRA on reduced catalysts occur at temperatures above 773K, with conversion in a mixture of H2, CO2, CO and minor conversion to CH4 and C2H4. On Cocontaining catalysts, the SRA occurs via pyrolytic mechanism with the activation of C3H6O by cleavage of C-H bonds, followed of C-C and C-O bonds and oxidation of C formed by H2O. The Ni-containing catalyst, in the presence of H2, is active at lower temperatures (523K) than Co-containing catalysts with conversion predominantly to CH4. The results indicate that the H2 instead of C3H6O reduce of NiO on surface and the intermediates of acetone activation on reduce Ni surface is hydrogenate to CH4 at low temperatures. The thermogravimetric analysis of used catalysts demonstrate greater carbon accumulation on Ni than on Co-containing catalysts.

    The thesis contains a study on the School in MST Camp: Institutionalization and Management of State Itinerant School Carlos Marighella. The problem of this study lies in the way of managing the traveling school in the MST camp, the contradiction is present with regard to the class struggle and interests defending, as Brazil is, par excellence, the land of large estates and, he, a deep social inequality in rural and urban areas, that can be characterized as social apartheid. In this regard, it is noteworthy that the construction of the Itinerant School has history and school history in the MST has the story of the struggle for agrarian reform. In these struggles, the Paraná bears the mark of the explosion of class struggle in the countryside, whose centrality is in the mechanization of agriculture, land concentration and construction of dams in Santiago Jump and Itaipu, which displaced more than 3,000 families from their land. In the struggle for land, northwest region of Paraná brings the land occupation and school occupation as dispute space. There is, in this struggle, the occupation of Fazenda Santa Filomena, in Planaltina of Paraná, and with it the construction of Camp Elias Gonçalves de Meura. This camp was built Itinerant School Marighella Carlos, who was born as a public school in 2004, which started teaching activities in a stable. Therefore, our purpose was to this school, meet its internal structure and forms of management. So our object is the school management. So we ask ourselves: How is the management of a school of MST in the capitalist state structure? There is an autonomous management from the State? Management mechanisms that are present in the Itinerant School? Collegiate bodies that are present in the school structure? How is the social control of the Itinerant School? In this sense, the school management is the MST or no state control over school management? Given these issues, our intention was to investigate the School Itinerant Carlos Marighella both the organizational aspects, the management, the administrative, educational and financial dimensions, from 2004 to 2013. Therefore, we undertook a bibliographic nature of research and interviews. In literature, the empirical sources consulted were the texts and MST works on education, and the documents produced by the MEC, SEED and State Councils of Education relevant to Education Field and Itinerant Schools. Besides these, we also drew the texts produced by several researchers who analyzed the Itinerant Schools in the different aspects of studies. Interviews were conducted with members of the MST Education Sector, educators and students of EI, public officials and school community camping. The reflections on the school management, despite being a singularity as pedógica experience, to be tensioned by the conflict of land, EI is not the government school, nor he directed. She is the dual management, but brings in your organization elements of the socialist school of work as selforganization in the training process. This is the meaning of this research thesis answered.

    In this Thesis we study in details one of the most astonishing application of quantum mechanics which totally departs from our common sense: quantum teleportation in continuous variables. We present a review of the postulates of quantum mechanics and quantum optics systems, in particular for Gaussian systems. After this review we apply these postulates in order to present one of the most counter intuitive applications of quantum mechanics, namely, the quantum teleportation protocol. We study in detail this protocol and we propose modifications in its construction aiming at an improvement in its efficiency. These modifications were made in order to take into account the realistic situations encountered in the implementation of the protocol, i.e., the fact that the entanglement, between Alice and Bob, is never perfect and the fact that states teleported by Alice are near the vacuum state. After this analysis we performed an extension of the teleportation protocol by proposing a multi-channel protocol and studied the case of two channels in parallel. Finally, we created the first quantum cryptography protocol that uses the continuous variables teleportation protocol in an active way. We showed that this protocol is robust to the beam splitter attack and that this protocol is the only one working with direct reconciliation and without post-selection over the 50% loss scenario.

    The need for satisfying deadlines and reducing costs made construction companies invest in the improvement of productivity throughout the steps of constructing buildings. This study aimed to stratify the workforce‟s productivity in employment categories during the execution of the plaster coating, showing productivity indicators values expressed in man-hours per square meter (Hh/m²) of executed coating so as to identify among the workforce‟s employment categories chances of improvement. As research strategy, it was used the field survey in five construction works with different types of buildings, where it was made a hard observation and labor productivity collection taking into account the occupation categories (Direct Work, Delays, Mobilization, Downtime, Displacements and Support) resulting in productivity indicators stratified in accordance to these categories. It was diagnosed that the values of the overall workforce‟s productivity ranged between 0.16 and 0.50 Hh/m², considering that the main value in the distribution of its fractions was in the occupation category of Direct Work, which ranged between 0.08 Hh/m² and 0.23 Hh/m² regarding the other categories. The higher the representativeness of main productive and auxiliaries categories (Direct Work, Support and Mobilization) over the categories associated with the unproductive activities (Downtime and Delay), the better the productivity detected, although strong statistical correlation was not observed. Regarding the category Direct Work, the best productivity of labor is achieved in the implementation of the coating on the ceiling over the implementation on the walls. Thereby, this work‟s main contribution is in the preparation of the analytical structure of occupation categories to the plaster coating department as well as the unfolding of workforce‟s productivity indicators in these categories for this department.

    Pre- development phase and corresponds to the activities ranging from identifying opportunities to generate product concepts. Throughout these activities there is a dynamic and complex flow of information about business strategies, requirements and market trends, technological alternatives and resource allocation. At this stage important decisions are made, and if misleading may result in failures in the performance of the new product. The subject has gained importance in recent years, however, there is still not an understanding on how to coordinate the activities of the predevelopment or which results are expected in this phase, therefore being a gap in the literature. This thesis aims to identify and analyze the practices, technical and tools what are adopted in front-end development in a sample of manufacturing firms. Through systematic literature review identified ten reference models for the front end development. These were published between 1988 and 2013 and seek to systematize the activities of pre-development and guide managers in conducting phase, proposing technical and management support tools. 57 different techniques have been identified. Through multiple case studies it was observed that all studied companies adopt referential models for conducting the activities of front end development. As in literature these models followed by companies differ mainly in relation to the number of stages or activities, but adopt some techniques and tools as well diffused in the literature. We observe that the most common practices in all companies can be grouped into early, middle and end activities, which divide the front end development in three distinct phases. For every moment of the predevelopment can be selected a set of techniques and support tools. These techniques and tools do not necessarily have to be adopted together because they have different natures, but are a "package" of suggestions to be considered. In addition, internal and external factors in the companies affect such practices. It was also possible to identify, in the companies analyzed, finding it difficult to measure the performance of the activities of the pre-development phase itself, and the PDP as a whole, so some possible performance indicators for this phase were suggested. Another difficulty associated with the use of these techniques and tools is that they require financial and time resources, and all require the skills of those who lead. Therefore, the most modern and best potential for achieving results technique can be ineffective if conducted by people who do not have necessary skills and appropriate technical support.

    This work aims to broaden the search for studies related to the History of Science, specifying the History of Chemistry and the concepts involved in these studies. In this sense, the objective of this research was to conduct a bibliographic survey of the scientific production on the History of Chemistry in Brazil, analyzing some Graduate Programs, as well as journals and events related to the field of Chemistry, mapping the academic production of recent years in relation to: quantities, objectives, keywords, target audience, methodologies, theoretical frameworks, and abstracts of the studies found, considering the methodological aspects discussed by Severino (2007) and Lakatos and Marconi (2011). The results obtained were forwarded in three aspects: quantitative analysis; mapping by titles and authors; and indexing of the works found. Thus, it is understood that this monograph contributes to the field, as it highlights the scarcity of works focused on the topic addressed here, especially in specific events of Education and Teaching of Chemistry, in addition to diagnosing main research trends.

    Suitable coordination systems are crucial to the sustained competitiveness of agribusiness systems. Nevertheless, some agribusiness systems have serious deficiencies in their integrated planning, generating with negative disputes between the members in the chain, which can lead in many cases to the loss of competitiveness. The orange agribusiness system, which has a significant importance as a currency generator and employment, not only in Brazil but also in many other countries, has faced serious problems of competitiveness. Disease threats, particularly, with the "greening" as the most critical, additionally the continuous competition for land with the sugarcane agribusiness system, have led the so-called "citrus belt" moving increasingly towards the southern state of São Paulo. This situation has led to increased costs and reducing the productivity and efficiency throughout the whole chain. The Brazilian citrus industry should search for urgent solutions, which cannot only bring longevity to the business, but also as a more critical issue: their own survival. Thus, this study aims to verify whether the gradual introduction of new varieties of orange and the development of a model of integrated planning within the technical of system dynamics can contribute to improve the performance and the competitiveness of this agribusiness system. The research method used was deductive hypothetical with the necessary information was gathered through semi-structured questionnaires and personal interviews with agents in the sector. The model was applied to the part of the citrus production chain, which covers the members of agricultural production and industrial processing. The results of the developed model showed that there are significant potential gains in performance, reflected in the increased EBITDA margin on the industrial processing side and in the net income per hectare and the price of the orange box on the agricultural production side, if they established together an integrated planning of production, crop-season to crop-season.

    The objective of this research is to analyze the film The Discreet Charm of the Bourgeoisie by Luis Buñuel (1972), by means of some concepts of the theoretical and methodological framework of Michel Foucault: "knowing" and "discursive statement" in its relations with the "power "and" truth ", and seek to understand the power in your workout in the film, and not only in its effects. Starting with some basics about "knowing" in Foucault, we mapped one filmic statement which appeared in some sequences, which is: "The noise that hides the discrete violence of the bourgeoisie." Therefore, we assess the "power and truth," these notions that became persistently present in the materiality of the film, prompting analysis mechanisms. Then conducted reflections on these principles by theory arqueogenealógica Foucault, then apply them to the analysis of the film. The research also presents aspects of the life of Luis Buñuel, traces relations between the military dictatorship of this movie and the Brazilian military dictatorship, and punctuate the experience of the director with the Surrealist movement his Catholic creation and exile in Spain in time of dictatorship. Buñuel all this shows in his work. We also established prior to analysis, a dialogue between Marx and Foucault in relation to the issue of power in relation to understanding the "bourgeoisie."

    The culture of work, comprising the values, ideas and shared behaviors between individuals in organizations, has been modified from the restructuring process. The objective of this research is to identify how the organizational discourse constructed by the media reinforces ideologically such transformations, generating a representation of the desired profile of the contemporary worker. For this, we analyze news from the magazine Você S/A on its Career section, based on categories of Discourse Analysis and sociological theory about the world of work. The topics more focused by the magazine were analyzed in relation to discursive aspects of intertextuality and interdiscursivity in written texts and images of the articles. Thus, it was possible to realize that organizational culture in media discourse follows the business management perspective, regulatory and uncritical. The ideological process hide the mechanisms of pressure and overload work by enhancing the desired values of the new worker's profile, based on autonomy, skills, flexibility and innovation. Figures such as coach, consultant, leader, entrepreneur and professionals related to human resources are central to the consolidation of work and organizational culture. In addition, there is a convergence between journalistic, business and educational discourses, focused on the executive worker training that compounds the public of Você S/A. The reports prescribe "recipes" that are assertive when discuss the employee's responsibilities, while the benefits are only in the bound of possibilities.

    Because the importance of invasive plant species in biological diversity reduction and environmental quality depreciation, there is great studies need addressing these organisms development, invasive potential and changes in nutrient cycling at invaded areas. We evaluate the development, invasiveness and debris input of Hedychium coronarium, aggressive herbaceous weed of wetlands, as well as the invasiveness of riparian communities. The two-year population dynamics study found increased ramets mortality and births during the winter season, indicating primary effect strategy for ramets recruitment. The in situ and in vitro decomposition experiments demonstrated low mineralization rates comparing with others same habit and niche of macrophytes. Sinusoid and exponential models demonstrates stochasticity of development and debris accumulation of H. coronarim in invaded areas. Rhizomes showed histological responses to different soil moistures. In high moisture soils, we found great aerenchyma development. Under low moisture, rhizomes showed greater starch granules accumulation. Removal experiments presented alternations in the preferential vegetative or reproductive investments according to soil moisture and habits of competitors. We also noted the use of rhizomes as food resource by capybaras during the winter season.

    In this work binuclear copper(II) complexes and mononuclear iron(III) complexes were studied as functional mimetic models of enzymes capable of catalyze the oxidation of catechols. Different structures of the complexes were obtained by synthesizing them with different Schiff bases, which possesses imine groups with aliphatic chains containing groups ranging from two to six carbon atoms between the nitrogen atoms, as well as cyclic substituted aromatic species between these atoms. These structures have allowed structural and electronic effects to be evaluated and correlated with the catalytic activity of their complexes. The binuclear copper complexes showed excellent catalytic efficiency in transforming the substrate 3,5-di-tert-butylcatechol to its respective quinone. The kinetic parameters obtained allowed the evaluation of how and which structural effects affect their catalytic efficiencies, being observed an increase in affinity between catalyst and substrate with increasing carbon chain between imines. It was also observed that the presence of substituents in compounds with aromatic diimines causes a lesser affinity between catalyzer and substrate and consequently a low catalytic efficiency. Catalytic assays with the iron(III) complexes have shown that regardless of the structural changes caused, none of them presented activity similar to the enzyme catechol dioxygenase. But those complexes which catalyzed the oxidation of the substrate to its respective quinone, being these changes accompanied for 24 hours of reaction. Although the substrate conversions were slow and low, trends were observed from correlations between structure and catalytic activity. The percentages of 3,5-di-tert-butilquinone obtained for the best catalysts among these complexes suggests that there is a step of forming a catalytically active species during the reaction time.
