The use of semiconductors for environmental applications and solar photoconversion has been widely explored recently. Due the intensive researches on renewable energy such as the photoelectrochemical H2 evolution from water splitting reaction, the design of new catalysts has been investigated. In this context, tungsten oxide – WO3 – is a promising catalyst for such application, however its conduction band is located at a more positive potential than the potential of water reduction, as a result WO3 does not have the ability to reduce H+ to H2. In the first part, this work deal with the synthesis of WO3 by the oxidant peroxide method, as a promising catalyst for this reaction. Tuning of the band-edge levels for the different synthesized catalysts was verified from Mott Schottky plot, and it represents the effective photoelectrocatalytic water splitting.In the second part, the study of heterostructuring TiO2 with WO3was investigated because of the possibility to mitigate the recombination of electron–hole pairs and therefore obtain more active systems for photocatalytic applications. The synthesis of WO3/TiO2 heterostructures was evaluated by hydrothermal method using three different routes: (I) precursors used as peroxo-complexes; (II) tungsten peroxo-complex and TiO2 pre-formed oxide; (III) pre-formed oxides as building blocks. The results showed by electrochemical characterization demonstrated how the electronic parameters (band edge positions, Fermi level energy and charge migration) affect the photocatalytic activity of heterostructures obtained by the distinct synthetic routes. The as-synthesized materials was investigated toward the photodegradation of organic dye (Rhodamine-B) under visible and UV illumination. The growth mechanism was observed to play a significant role in governing surface and interfacial properties, which has a direct influence on xvi materials photoactivity. The band edge positions for the materials was determined from Mott Schottky plot and the experimentally determined energy diagram is consistent with the formation of a type II heterostructure for WO3/TiO2 and it is well correlated to recent reports in literature. As a result, the photogenerated electrons and holes can be spatially distributed in two different crystalline phases in contact and the charge recombination is inhibited, which is efficient for photocatalytic reactions.Additionally, regarding the energy diagram obtained for the heterostrucutres, it is possible from the thermodynamic aspect the use of those structures as promising candidates for the photoelectrocatalytic water splitting, since the band positions are sufficiently large to overcome the character of this reaction.

Inclusive education allows the presence in the mainstream classroom students with disabilities, disorders and giftedness and talent. For the gifted and talented students are subjects of the educational process, it is important that the teacher knows what's giftedness and talent to identify the students in the classroom and they can be assisted. With this research, it was intended as a general objective to verify if there is indication of gifted students in a 3rd year class and the 4th year of elementary school from two public schools, a total of four investigated classes, applying the tools Observação Direta em Sala de Aula, Lista De Verificação de Identificação de Indicadores de Altas Habilidades/Superdotação, Lista de Verificação de Identificação de Indicadores de Altas Habilidades/Superdotação-Área Artística, and Lista de Verificação de Identificação de Indicadores de Altas Habilidades/Superdotação-Área Corporal Cinestésica. The specific objectives were: To know the gifted and talented students indicated in schools with indexes appointed by (Index of development of basic education (IDEB), namely: a school with the lowest levels ( 3rd and 4th years ) and one with the highest levels ( 3rd and 4th years) at elementary school in a midsized city in the countryside of São Paulo, Brazil and to know the professional profile of the participanting teachers at the research, both in the academic aspect as in their teaching experience as well as theoretical knowledge on the subject of the giftedness and talent. The method was descriptive research. We used a questionnaire to characterize the participating teachers and knowledge on the subject. The results were: School A: (IDEB below) : With the Guia de Observação Direta em Sala de Aula was nominated four students (two of 3rd year and two of 4th year). The LIVIAHSD appointed a student of 3rd year. School B (IDEB above): the Guia de Observação Direta em Sala de Aula indicated nine students (four of 3rd year and five of 4th year). The LIVIAHSD indicated only two students in the 3rd year. The LIVIAHSD-AA and LIVIAHSD-ACC instruments did not indicate any student. The results still showed that: a) the instruments seemed effective to point gifted students; b) LIVIAHSD, LIVIAHSD-AA and LIVIAHSD-ACC didn’t have the same efficiency of the Guia de Observação Direta em Sala de Aula, requiring their completion for comparison and analysis; c) The IDEB schools up and down revealed that there were gifted students, independently the indexes of IDEB, and d) The most of teachers surveyed made explicit about the understanding of the giftedness and talent subject.

This graduation term paper aimed to comprehend how using Arts can contribute to teaching English Language Arts in a more significant way for elementary school students. The research started with the author´s interest in Arts, specifically in dance, mixed with the challenges of being an English teacher. The study is characterized as exploratory qualitative research and field research (as for its goals) and as a case study (as for its procedures), which came from a high bibliographic search, delimitated by themes (research for papers related to the object of study), linguistics (search for papers published in English and Portuguese), and main sources (books, magazines, paper work, etc). Finally, the field data collection happened at a bilingual education school in Sorocaba, between 2014 and 2015, followed by organization and analysis of the collected data. The study was divided into three chapters. The first presented several experiences where teachers integrated Arts while teaching other school subjects and the reflection about the integration of areas in educational practices, which justifies and legitimizes the research. For this reason, the same chapter conceptualizes the term interdisciplinary, providing the research with a deeper comprehension about the interdisciplinary teaching practices. The second chapter presented the methodology used to develop the paper, describing the set of processes used to write it. The third chapter described the data analysis gathered at the school, which involved activities implemented with five to ten year-old students and photographs of these activities.

ABSTRACT This paper aims to demonstrate the importance that libraries should give to the correct storage of bibliographic items in their collections, in order to increase the useful life of the items and facilitate their recovery. This paper will point out the main procedural errors committed in storage and suggest procedures that are best suited to meet this purpose. The importance of standardizing storage procedures and their usefulness will be shown not only in terms of conservation of items, but also in the recovery of information by users and in terms of library administration. Aspects such as: conservation, location, quality of materials, adequate and planned physical space, inventory, security of bibliographic items, behavior of professionals involved in storage, supervision of storage, thinning policy, marketing to users and guidance to users will be the main points addressed in this paper. Comparisons will be made between storage methods in order to demonstrate how neglecting bibliographic items can be potentially harmful not only to the collection itself, but also to the institution's image among its users and the community in general. We will seek to use the epistemology of the administration area to improve the flow of the storage process and the transmission of knowledge. The conclusion of the study allowed us to conclude that only with standardization, organization, strategy, adequate procedures, socialization and collaboration of all involved will we be able to transform our institutions into reliable information reference centers that are accessible to users in general.

Remanufacture can be defined as the industrial process where products worn, broken or used are restored getting a new life. Currently, many companies remanufactured products, driven by economic or environmental benefits, or by the force of law. Performing materials management and inventory in this environment with peculiar characteristics efficiently, it is necessary to contain waste with excess inventory or lack of material for production. In addition, the purchasing department holds an important position in most organizations, as parts, components and supplies can represent 40-60% of the final value of sales of any product. Thus, the objective of this work is the proposition and implementation of inventory management models in a remanufacturing company of fire extinguishers and analyze the efficiency of these through the expenses accumulated during one quarter. Based on preliminary analysis of the historical consumption series of selected materials, three propositions were suggested. The results show that when we analyzed the implementation of the proposals in material individually, there were cost reductions and better regularity in buying some, and in others, the proposals have not brought benefits. With the results, it is suggested that the application of the propositions, even partially for some materials, can help to increase the company's competitiveness with the availability of capital that was previously allocated to the purchase of these.

Considerando la importancia de la educación para las diferencias en el contexto actual, existe una necesidad urgente de incorporar / adaptar temas problematizados basados en teorías poscríticas, como género, raza, etnia y sexualidad, en los materiales didácticos de lenguas extranjeras. En este sentido, este trabajo propone la realización de un prototipo de Unidad Didáctica para la enseñanza de la lengua española, no con el fin de proponer soluciones, sino de plantear interrogantes y reposicionamientos respecto a la práctica docente y la elaboración de materiales didácticos para la docencia. , con el objetivo de una ciudadanía plena y emancipadora. Para ello, este trabajo presenta reflexiones realizadas en la incipiente área de investigación de la Lingüística Aplicada Queer, concebida a partir de los entrelazamientos metodológicos de la Teoría Queer y la Lingüística Aplicada, y su potencial para un enfoque no esencialista y problematizador de las categorías identitarias, con el propósito de promover la práctica de la literacidad queer pensada para la diferencia.

Este trabajo tiene el objetivo de investigar la situación lingüística de Paraguay, más específicamente de Ciudad del Este. A través de entrevistas a un grupo de personas de esta ciudad, buscamos mostrar cómo es la relación de los participantes con las lenguas que son oficiales en el país, el castellano y el guaraní, y también con el portugués, lengua adicional bastante utilizada debido a la gran circulación del comercio y de la fuerte presencia de brasileños en esta región. También visamos comprender la relación de estas personas con lo que se clasifica como “yopará” (definición en castellano) o “jopará” (definición en guaraní). Para entender como se ha formado la distribución lingüística de la región, abordamos brevemente aspectos históricos, desde la llegada de colonizadores europeos en esta región de América del Sur hasta los días actuales en el país. De la sociolingüística, tomaremos términos como “bilingüismo” y “diglosia” y analizaremos el caso de la región de Ciudad del Este. A través de una selección de preguntas para componer un cuestionario, elaboramos algunas secciones de entrevistas, en las cuales esperamos comprender la importancia dada por este grupo de personas a las lenguas habladas en el país, y, más específicamente, en la ciudad donde fue hecha la coleta de dados de esta investigación.

Perform fast and accurate recognition of objects is still a challenging task in many applications. In this sense the techniques based on detection and description of image features and in correspondence (matching) has been set up as an important technological evolution in the development of object recognition systems. The most common procedure for object recognition systems is that, given some knowledge about the appearance of some objects, one or more images are examined to determine whether the object is present and the location thereof. Recognition of flat objects, such as images and logos is part of that context today and the approaches proposed for vehicle logos recognition problem. This problem has been one of the domain issues in automatic identification solutions. But realize the recognition of logos vehicles in quick way to images while maintaining the precision of the method employed is still a problem. On the other hand there is also the problem of enabling the application of the method speeded Up Robust Features (SURF) in recognition solutions objects. This method makes it possible to identify points of interest in images quickly and robustly. This paper proposes the development of an approach based on image processing and computer vision techniques to carry out reconnaissance vehicles of logos. The proposed method makes use of the SURF algorithm to perform recognition logos vehicles, combining algorithm with other techniques, such as the Canny method, Conci, Carvalho and Rauber, ROI, KNN and RANSAC to solve the problem, performing recognition the logos of vehicles from 45% to 100% of the images analyzed in a good runtime. The development of this research demonstrate a possible alternative choice for the logos of recognition problem of vehicles through efficient use of a model SURF method.

This research seeks understanding how different transvestite's generations that prostitutes themselves in the countryside of São Paulo built their bodies and subjectivities. I seek to understand the existence of the pressure between this identity project and the creation of two categories, the older and younger, observing the detachment and existent approximation between different generation of transvestites, just like specific valuations of some bodies and behaviors from each one of them. The study realized in Sao Carlos and Ribeirao Preto undertook ethnography at the prostitution areas and the transvestites homes, combined with online contacts through social media like Facebook©. Based on Queer theory, the Brazilian studies about the travestite‟s and the the idea of "generationality" and aging, I seek the creation of particular idea of being young and aging as travestite for the ones that prostitute themselves. Seeing that for this group aging is not only related with the age but with a specific relationship with the body, the job market and the social relationships that develops and keep the environment where they live.

This research aimed to understand the discourses about the Ronda Ostensivas Tobias de Aguiar (ROTA), focusing on the speech of Police officers and politicians over control the "organized crime." Therefore, we analyzed two recent episodes of "Confrontation" between Police and incriminated subjects (Itatiba - SP in May 2011 and Várzea Paulista - SP, in September 2012) that ended with large numbers of "Suspects" killed. We took this two emblematic cases as a way to cut temporally two distinct periods, before the so-called " public security crisis " apparent normality, and the other period in which the socalled" crisis "occurred, producing increase homicide rate in São Paulo. Documents were analyzed as case of studies, master's workes and professional thesis produced by officers in Polícia Militar do Estado de São Paulo (PMESP), News, newspapers, press officer of the Secretary of Public Security and speaking managers of Public Security. As a significant result, we found that since 2009, the State of São Paulo, there was a direction of PMESP activities in "combat organized crime "that had the support of other sectors of the justice system and state administration, such as the Public Ministry and Secretary of Administration prison that provided information to ROTA, looking for integrated approach against "PCC". The integration between agencies was maintained in relative secrety, while procedures adopted in the "fight agains to organized crime" remained opaque by the whole process, reflecting praticies of a militarized strategy favoring lethality and use of force as means of crime control, and instead of controlling the "violence", he turned out to produce it, especially in the year 2012.

This study aims at analyzing the constraints in the work of the professor-researcher in regard with the innovation policies. The hypothesis is that the current innovation policies progressively link the work of the professor-researcher to the business sector. In order to analyze the hypothesis, the political and institutional relations of the University of São Paulo were studied, more precisely in the campus of Ribeirão Preto, as well as their articulations with public-private sectors and partnerships. Documentary analyses and data collection on innovations, applied researches, incubator companies and productions and service rendering interpreted by the area of Science and Technology were held, as well as four semistructured interviews with innovation agents. It was found that the University of São Paulo constituted its own institutional arrangements by means of articulations with institutions specifically in the municipality of Ribeirão Preto. Furthermore, institutions of the university are relevant in this process, such as USP Agency of Innovation. However, it was found that Fundação Instituto Polo Avançado da Saúde de Ribeirão Preto (FIPASE), a municipal foundation which supports innovation, encourages specific political and institutional devices for the incentive and development of researches applied to the demands of the business sector, in order to induce the researchers in the university to carry out certain practices of innovation. Consequently, it also induces part of the graduation research of the campus to turn into applied research centers, enabling the creation of spin-off companies. It is pointed out that these institutional arrangements for the development of the applied research, however, would not be possible without relevant changes in the professorresearchers‘ working hours, undertaken by them, based on decisions in the university which result in regulations and resolutions that make flexible and encourage the relation university-company. It can be concluded that, in spite of the narrowing of the link between the work of the professor-researcher in the Science and Technology area and the business sector, the innovation policy in the campus of Ribeirão Preto meets the interests of the academic community much more than the ones of the business sector itself, and that, in this process, contradictorily, it is the university that reconfigures itself to the patterns of the logic of the businesses, typical of the companies, rather than the companies that modify themselves or develop the practice of research and production of the technological knowledge, typical of the university and the scientific area.

Code inspection is an important activity to assure the software quality that, in some cases, shows a better performance than the testing activity. Its application depends on the use of reading techniques that assist the inspector both in understanding the code and in executing the inspection. Although there are some reading techniques that support code inspection, Stepwise Abstraction, for example, was set to the procedural paradigm and requires that even the simplest code be abstracted. Other techniques such as Checklist, Use Case based, etc., are prone to the inspector’s experience since they do not provide a systematic procedure and they are not supported by facilitating resources. A computer-aided code inspection providing visualization facilities for applying Stepwise Abstraction – the CRISTA tool - was developed in another work of this research group. This tool has shown to be an effective and efficient approach for code inspection. Objective: To present the reading technique KIRT (Key-Information Reading Techniques) that was defined through operational scenarios, in order to establish systematic guidelines for conducting the code inspection. KIRT was based on reading patterns obtained from the analysis of the inspectors’ behaviors, considering features of the object-oriented paradigm, and using visual metaphors that guide the inspector during the inspection. Method: Considering the intention of understanding how the code inspection is carried out in practice, the research was based evolutive cycles, performed through four cycles that were the basis for defining and evaluating KIRT. In each cycle, studies were performed to generate subsidies for supporting subsequent cycles. The KIRT technique was set with the main purpose of identifying defects and, in addition, source code improvements. Once defined, three experimental studies were conducted to: (i) evaluate the contribution of the visual metaphor implemented in CRISTA tool for defects identification; (ii) evaluate KIRT technique (using two different metrics) regarding the effectiveness and efficiency in the identification of defects and source code improvements; (iii) evaluate KIRT technique in relation to the Checklist technique. Results: The results of the experimental studies showed that (i) the visual metaphor influenced the number of source code improvements and false positives identified; (ii) KIRT technique (instantiated by two distinct metrics) was complementary; (iii) the effectiveness and efficiency of the KIRT technique were better than Checklist. Conclusion: In the experimental studies the KIRT technique showed satisfactory results regarding the effectiveness and efficiency in identifying defects, and generated few false positives. Moreover, the KIRT technique identified more source code improvements than Checklist. Based on the results we can say that KIRT technique can be used for code inspection in practice, mainly because they are supported by CRISTA, which provides procedures and visual metaphors for conducting the code inspection activity. Consequently, if they reach the objective of identifying defects, we can say that they contribute to the overall quality of the software.

The remarkable advances in scientific research of materials for ever demanding service requirements has led to novel developments of biomaterials, especially in the field of surgical implants. In this field, the semi-crystalline thermoplastic PEEK (poly-ether-ether-ketone) has been selected as one of the most suitable for orthopaedic applications. Due to its excellent short and long term mechanical properties and also associated to its elastic modulus compatibility with that of the human bone, the polymer safely fulfills the mechanical and biological requirements for injection moulded implants with complex design. However, as also verified with metallic implants, the PEEK osteointegration is slow and, therefore, can be enhanced with bioactive ceramics coatings of hydroxyapatite (HA), obtained mostly using plasma spray technique. However, as the high temperatures related to the plasma process can impair significantly its mechanical performance, this study aims to investigate the influence of the plasma spray process on the mechanical fatigue behaviour of injection moulded PEEK coated with HA. Using mechanical test specimens with three distinct treatments: (i) PEEK as molded, (ii) PEEK with thermal plasma shock and (iii) HA plasma coated PEEK, several characterization techniques, which include X-ray diffraction, differential scanning calorimetry (DSC), short-term tensile and flexural tests, dynamic-mechanical thermal analysis (DMTA) and deformation-controlled flexural fatigue tests were performed. The quality of HA coating was considered adequate, as identified by X-ray and SEM analysis. The experimental data on the main mechanical characterization of HA coated PEEK, demonstrated that the plasma treatment contributes to a significant increase in the short-term flexural elastic modulus and strength properties and also reduces the stress relaxation rate (residual stress) during the fatigue cycling up to one million cycles. These increases in the flexural stiffness and residual fatigue stress of PEEK are induced by a increase in the polymer crystallinity content and the presence of additional thermal residual surface stresses on the PEEK surface exposed to the plasma thermal shock, as identified by DSC and DMTA analysis.

This research is part of the institutional evaluation field, in particular, the evaluation of undergraduate courses, aiming the development of a methodology for analyzing the results of the evaluation process as a way to subsidize on a broad perspective the decision-making, and more specifically, the reformulation processes. The proposed methodology seeks to integrate information from different evaluation processes related to undergraduate programs, with emphasis on those established by the Sistema Nacional de Avaliação da Educação Superior (National Higher Education Evaluation System, SINAES) to analyze them critically. In this case, the report of the institutional self-assessment, the report of the Commissions assessment in loco of the Instituto Nacional de Estudos e Pesquisas Educacionais “Anísio Teixeira” (National Institute of Educational Studies and Research “Anísio Teixeira”, INEP), coming from the regulatory processes of recognition and renewal of recognition of undergraduate courses and the course report of the Exame Nacional de Desempenho de Estudantes (National Examination of Student Performance Report, ENADE). In addition to these, it will be exemplified other internal and /or external indicators that may be included when they’re relevant to the course. The objective is to stimulate analysis of the results of evaluation processes which underwent certain undergraduate courses, organizing information and making it accessible to those involved with the course, especially the academic bodies responsible for formulating a critical and systemic diagnosis on the implementation of the Educational Project Course and, when appropriate, for proposing modifications. The theoretical framework proposed for this analysis is based on the concept of emancipatory evaluation, whose basic principle is the pursuit of transformation of a given reality from a participatory assessment process. The preparation of the methodological proposal was preceded by bibliographical and documentary research that theoretically grounded it and then was developed experimentally in an undergraduate degree at UFSCar. The methodology we used for the development of the proposal was the action-research, and in order to validate it, it was held the meeting of the focus group with the teachers of the course. The central idea of the proposal is to collect, organize and analyze the indicators resulting from internal and external evaluation processes of undergraduate courses, organizing the information into large dimensions for a critical comparison of results from different sources. In this paper, a pilot spreadsheet was developed in twelve dimensions that organizes the extracted results from different sources of information, thus contributing with a comparative analysis and critique of each dimension evaluated. The results showed that this methodological approach proved to be appropriate to support the analysis performed by teachers on the results of evaluations to which the course has been submitted. The authors emphasize the importance of the multiple evaluation processes for the construction of a broad diagnosis of the current situation; More than that, it was found that the process of analyzing the information organized as proposed favors collective discussion on the Pedagogical Project of the Course and encourages educational evaluation culture in its formative and emancipatory sense; It showed up, too, the importance of an education expert who has knowledge of the methodological approach and on the evaluation processes.

The Statistical Process Control (SPC) is recognized in the literature as one of the main tools for controlling and improving the quality and productivity. The control chart is a central element of the SPC; and these, statistical tools whose efficiency depends on certain skills and organizational behavior. With regard to the results to the organization, it is observed that the use of control charts can be divided into two groups: those that can be directly attributed to reduced variability called hard; and those associated with the motivational aspects, or organic, called Soft. Despite the arguments in favor of SPC survey, a study conducted in the automotive sector shows that about 70% of companies have some difficulty in conducting their activities related to the SPC. On this, the literature indicates that factors related to methodological, statistical and managerial aspects of control charts of the implementation process are conditions for the success of a structured plan of implementation of the SPC. Given this situation, it is objective of this thesis contribute to an effective use of control charts by national companies, and to advances in research. To this end, we opted for a field survey to capture and describe the perceptions of experts who use control charts and working in the automotive industry. The field research was structured in three basic dimensions - statistics, methodology and management, and the results achieved by the use of the SPC, divided into Soft and Hard. The method used was based on a survey, which has a population of interest was the managers of SPC programs that use the control charts for more than 01 years in the auto parts industry. This survey was sent to 98 individuals in the population of interest, identified in the Official Guide Auto parts Industry (2014), which resulted in 37 questionnaires and valid for analysis. The results of this field research validated the hypotheses in part the theoretical framework, but showed, besides the complexity and importance of methodological and managerial aspects in the implementation of the SPC, there is a significant gap between theory and practice. This may partly be explained by the dissonance between the main scientific advances in the field, especially in the statistical aspects, and the controversies about the real benefits of SPC program. As a result of this thesis is recommended that field research has been done for that to report real success stories of the SPC; whose cases are examined in depth so that good practice is disseminated in the academic environment.

This research aims to outline and scrutinize the set of musical practices and repertoires widespread among the Macushi, an indigenous population of Karib linguistic affiliation who currently inhabit the fields and valleys of the basins of Branco and Rupununi rivers, a region that is politically divided between Brazil and Guiana. This investigation is temporally restricted to the last decade – between 2005-2015 –, and geographically restricted to the population situated on the Brazilian side, more specifically on the territory currently known as Raposa Serra do Sol. This study intended to detail the practices, significations and meanings attributed to different musical rhythms and repertoires of Makuxi in order to understand what kind of motivational factors were implicated in the the spread of forró rhythms and in the reworking of traditional musical rhythms, notably the parixara and the tukui, in a political context in which such musical repertoires were reinterpreted and used as "cultural performances".

The sugarcane has great economic importance in Brazil. To keep productivity several biotic and abiotic factors can positively or negatively influence. Among them, weeds, nematodes and synergistic action between pesticides to control both can be cited. Thus, the present work aimed at studying possible common weeds in the mechanized harvesting system that can serve as hosts for the root knot nematode: Meloidogyne incognita and / or M. javanica and study the interaction between herbicides and nematicides used in the groove planting of sugarcane. Two experiments were carried in a greenhouse at the Agricultural Sciences Center (CCA-UFSCar), Araras, SP. The first experiment evaluated the host status ten weeds, as follows: Ipomoea triloba (Dammer), Merremia aegyptia (L.) Urban, Luffa aegyptiaca Mill, Euphorbia heterophylla L., Ricinus communis L., Crotalaria spectabilis Roth, Mucuna aterrima ( Piper & Tracy) Holland, Chloris polydactyla (L.) Sw., Digitaria horizontalis Willd., Urochloa decumbens (Stapf) RD Webster and the control (tomato Santa Cruz Kada) when inoculated with M. incognita or M. javanica in a completely randomized design in a factorial 11 x 2, with six repetitions. The plants were inoculated with 2.000 eggs and J2, and there were three plants per plot (6.000 eggs and J2 per pot - repetition). Sixty days after inoculation (DAI) the plants were removed and evaluated according to the reproduction factor (FR), final nematodes population (PF) and reproduction index (IR). In the second experiment the effect of interaction between two nematicides applied in contact with the stalks was evaluated. The nematicides tested were: benfuracarb (5,0 L ha-1) and carbofuran (50 Kg ha-1), and the herbicides applied preemergence of culture were: sulfentrazone (1,6 L p.c. ha-1), diuron + hexazinone (2,5 Kg ha1), saflufenacil (0,14 Kg p.c. ha-1) and amicarbazone (1,5 Kg p.c. ha-1). The experiment was carried in a completely randomized design in a factorial 15 x 5, with four replications in three sugarcane varieties (RB867515, RB975952 and RB975201). The first factor was corresponded to the 15 treatments and the second, to the five evaluation periods. Evaluations of intoxication symptoms were performed at 7, 15, 30, 45 and 60 days after emergence (DAE) of culture. In the last assessment biometric parameters height (cm), leaf area (cm²) and dry biomass of the aerial part (g) were evaluated. Regarding to the host status of weeds, it was found that L. aegyptiaca behaved as host of both nematodes, with FR > 1, higher than the control. The D. horizontalis was classified as host of M. incognita and non-host of M. javanica. C. spectabilis had the lowest FR and PF. R. communis and I. triloba present galls when inoculated with M. incognita, but were not considered host for presenting FR < 1. None of the weeds tested was considered immune, that is, with RF = 0. Regarding the interaction of herbicides and nematicides in all treatments, plants recover 60 DAE, and in treatments with the use of sulfentrazone increase in symptoms of poisoning was observed. As for the biometric parameters evaluated at 60 DAE, there was no statistical difference only in the variety RB867515 for height. In this case, the treatments amicarbazone / benfuracarb and amicarbazone / carbofuran plants were higher than the control and other interactions.

In this research work, we address concepts related to Financial Mathematics. In this way, we have developed a methodology of teaching which is different than traditional method. In addition to the traditional content of this school stage (Percentage; Accruals and discounts, simple interest or compound) also approached contents that are usually presented only in courses aimed at forming a professional who has knowledge of finance in the fields of Business Administration, Economics, Accounting, etc. . These contents were financing with fixed installments, amortization and application systems with regular deposits. In our methodology we value teamwork, problem solving, research and working with tools that are available to any individual, such as the calculator (scientific), the "Calculadora do cidadão", an application available by the Central Bank and the www.calculador.com.br site.

In 2001, Larissa Mies Bombardi performed a case study regarding the Agrarian Inspection Law, and more specifically the Capivari agrarian core, founed in the 1960s and that became a rural neighborhood. The present paperwork seeks a reviewing of this case study in order to approach the economic and cultural changes expressed through spacial transformations that took place between 2001 through 2015. The goal consisted in understanding the farming production processes in this core and the trasnformations ocurred since Bombardi's study, upon the concept of reproducting peasantry, of the peasants as a reproducting unit. For the conceiving of this work, first and foremost, a study of Larissa Bombardi's “O Bairro Reforma Agrária e o processo de territorialização camponesa” took place, hence the book was taken as primary reference. After, there was the accomplishment of field research, with numerous interviews held with different profiles of local dwellers. Beyond that, the discussion regarding the changes and transformations that took place since Bombardi's study and the neighborhood and the peasantry's current situation, as of 2015. After that, there's a reflection concerning education in rural schools with a singular perspective that englobes the peasant reality. Thus, it's concluded that the peasantry's deal shows it's modifications and adaptations as they happened through the years, given the numerous difficulties regarding their reproduction, as well as “mechanisms” adopted for survival and continuity of this class as expressed by the different dweller profiles compiled in this paperwork. Furthermore, it's concluded that such cultural and social modifications impact directly in the neighborhood's configuration.
