In the race to improve stock management there are two approaches, one based on the Japanese philosophy of Lean Production and the other based on the implementation of information technology that improves the flow of information an reduces response times in the supply chain. These study aims to understand the impact of a White Goods Maker on stock levels of a solution that combines both approaches, i.e. Electronic Kanban via internet, which is a hybrid form of Kanban, using Information Technology as a control and management method. Using Action Research methodology, the implementation process of this tool was analysed through stock turnover indicators, enacting three cycles that include data gathering and intervention in the observed reality. This study led to the conclusion that the implementation of Electronic Kanban contributed towards the improvement of the stock turnover of the company in question.

In order to analyze the microstructure and to know the dynamic softening mechanics that take place during the hot work in F 138 stainless steel, physical simulation was carried out through continuous isothermal hot torsion tests in a wide range of temperatures and strain rates, covering the real conditions of processing used in the manufacture of orthopedic implants with this material. The plastic flow stress curves obtained in this study showed a typical behavior of dynamic recrystallization. Also was determined the peak and steady-state stresses (σp, σss) and strains (εp, εss) and also the value of apparent activation energy for F 138 stainless steel, which is Q = 475kJ/mol. Through the curves of work-hardening rate vs. equivalent stress (θ vs. σ), the values of critical stress (σc) and strain (εc) for initiation of dynamic recrystallization are obtained. The metallographic observation was used to measure the average grain size under all deformation conditions, and also for the pre-deformed grain, D0 = 85.1μm. Thus it was possible to obtain empirical mathematical equations for the studied steel, which relate the processing parameters with the average grain size, since the resulting grain varies with processing conditions. The obtained data in this study will form a database which could be used in softwares of thermomechanical processing numerical simulation, which will permit the previous evaluation of resulting microstructure in a hot work processing of this material.

Disintegrins are small cysteine-rich proteins with an RGD motif isolated from viperidae snake venoms. DisBa-01, a recombinant RGD-disintegrin from Bothrops alternatus snake venom, inhibits melanoma cell metastasis and also platelet aggregation in murine models by interactions with β3 integrin cell receptors. Also, this RGD-disintegrin inhibits human microvascular endothelial cell (HMEC-1) proliferation in vitro and angiogenesis in vivo. Alternagin-C (ALT-C), a disintegrin-like protein from Bothrops alternatus, is a potent inhibitor of the collagen binding to α2β1 integrin which plays an essential role in the adhesion of normal and tumor cells to the extracellular matrix. Also, this protein can modulate angiogenesis where low concentrations of ALT-C positively regulate the formation of new blood vessels, whereas high ALT-C concentrations negatively modulates this process. This work presents the effects of DisBa-01 and ALT-C: 1) on the adhesion of breast cancer invasive MDA-MB-231 cells to the ECM proteins and to the subendothelial matrix produced by HUVEC (human vascular endothelial cells) under static and dynamic conditions; and 2) on the VEGFRs expression on endothealial cells. ALT-C inhibited tumoral cell adeshion to almost ECM proteins individually and also to ECM. Only 10000nM ALT-C inhibited tumoral cell adhesion to the HUVEC matrix under static conditions. Under flow, tumoral adhesion were inhibited by 100nM and 1.000nM ALT-C. Flow induces α2β1 activation in endothelial cells and MDA-MB- 231 cells expressed high levels of α2β1. Thus, a possible activation of this integrin by the shear stress could enhance its interactions with ALT-C. DisBa-01 had no effect on the tumoral cell adhesion to HUVEC matrix under static conditions. On the other hand, under flow the RGD-disintegrin strongly inhibited tumoral and platelet adhesion. Thus, a possible activation of αVβ3 by flow could enhance its interactions with DisBa-01. About VEGFR expression, DisBa-01 down-regulated VEGFR-1 and VEGFR-2 expression in almost all tested concentrations. ALT-C up-regulates VEGFR-2 expression at lower concentration. These results can explain at least in part the effects of DisBa-01 and ALT-C in angiogenesis. The anti-adhesives and antiangiogenics ALT-C and DisBa-01 properties may be helpful for the study of tumoral metastasis as well as in the design of new therapeutic agents targeting tumor cell adhesion on extravasation and invasion steps.

The aim of this research was to analyze the effectiveness of the implementation of a Program of Support for Inclusion of Multi Disabled Students using techniques such as MAP and PATH as facilitators. The techniques disclosed by Pearpoint, Forest and O'Brien proposed a work centered on the person and acting with a positive vision of the future developed by groups where families, professionals and community members participate. The participants were four students between 7 and 14 years of a specialized institution that is in the city, the one that serves more students with multiple disabilities, and they began to be a part of the category of "participating beneficiaries." Worked in groups four facilitators participants 1', family members; four "facilitators participants 2", professionals of the specialized institution; and four facilitators participants 3 , members of the general community. It was proposed and carried out three meetings to develop the technique MAP for the removal of the needs and characteristics of each "participating beneficiary", to outline a plan of action. There was full involvement of participants. Six meetings were proposed with the PATH technique for monitoring the actions and made six in a group, five in another because the difficulty of one of the members and four in two other groups because of problems of prohibition of accessing roads. Requirements were raised to improve the educational programs to encourage the development of communication, activities of daily life, inclusion in regular schools, inclusion in the general community, the need for diagnosis, family support and effective relationship between education and health areas. The actions performed successfully forward improvements in care of the specialized institution, getting advice online first and then, presence advice with a three-day seminar for parents and teachers, all subsidized by national and international institutions. It was started a work on monitoring activities of daily living at home and social inclusion in areas of "participating beneficiaries" focusing mainly the churches that are available. The diagnoses were scheduled in a philanthropic hospital care and that provides a predictable treatment and it was got aids of volunteers so that families could travel to the state capital for these services. Three of the "beneficiaries participants" sought the regular education system, where only one has registered but he could not attend for lack of educational help. It was initiated in this case, a work in partnership between management, teachers and the school's specialized institution, volunteers and the researcher to achieve the inclusion. It can be concluded that the techniques MAP and PATH facilitated the actions to improve the family, social and educational inclusion because they followed the plan. It is desirable that the groups would have a greater number of members and that facilitators of the community could join to the centered group on the person and also to a group of volunteers to maximize the overall effectiveness of actions. Also, the partnership achieved through the regular school, in a case could be extended to all, encouraging the exchange of shares between the regular education, special education and health services.

Manufacturing systems with shared resources have been designed to meet the market needs, which require high quality products, low cost and the guarantee of the conditions agreed with the customer. The production scheduling in a manufacturing system is a complex task due to its combinatorial nature. Several studies show the use of search methods, such as Genetic Algorithms (GAs) and Tabu Search (TS), applied to the refinement of the production scheduling problem. The GAs present as disadvantages, the premature convergence, the lack of search intensification mechanisms in promising regions and also the lack of mechanisms which maintain the diversification of the population. In order to make GAs more effective in their search, by avoiding the premature convergence and ensuring the population diversity, some mechanisms are added to them so as to adjust their parameters during the search process, the so called Adaptative Genetic Algorithms (AGAs). However, these mechanisms do not guarantee the search intensification in the promising regions found. On the other hand, the TS presents mechanisms of search intensification and diversification, although its computational time depends on how optimal its initial solution is (solution by which the search process starts). In order to overcome the limitations of the traditional search methods, the Hybrid Algorithms (HAs) have been developed. They consist of the association of one method with another so that one helps the other in its deficiencies . This dissertation proposes the development of a Genetic-Tabu Algorithm (GTA) applied to the problem of the production reactive scheduling in a manufacturing system with shared resources, in order to ensure good compromise between makespan values and feedback time. The TS will be a functionality added to the AG and to the AGA, in other words, it will be a procedure to refine the individual(s) of the initial position and also to refine the individual obtained by the search methods. Tests have been conducted to determine which selection method (roulette or tournament) is more adequate for the definition of the neighborhood structure and also for the definition of the time to apply the mutation operator. Besides, other tests have been conducted by using different ways to calculate the makespan; one of them proposed in this dissertation and the others by Deriz (2007) and by Sanches (2008).

The tax planning is necessary for there to be a rational application of resources and improvements in basic infrastructure for the municipality. Therefore, the assessment and questioning of the results indicated in the Generic Plant Values can provide information to the legitimacy of taxation more fair and accessible. This study evaluated the consistency of values existing plant in São Carlos - SP with respect to income levels provided by the Brazilian Institute of Geography and Statistics (IBGE). The methodology used algebra through the Spring software. The results indicated possible inconsistencies between the income strata and venal values established. It is concluded that the plant venal values could be more efficient if they changed the criteria for charging for urban voids and taken into account the income strata of the taxpayer.

In search of qualification, the nursing searches increasingly a continuous update of all the team. One of the strategies that can be used for professional training is the education in service. In this perspective, for the creation of educational projects for training, the nursing has several technological resources in the health institutions and the computer is a facilitator of teaching activities and upgrade. The use of distance education mediated by computer finds wide application in the educational process, providing cost savings and increases the flexibility of teaching. In this context, this project aimed to develop and evaluate an educational content about pressure ulcers to the EAD. For this, placed a survey of the knowledge of a nursing team who worked in an outpatient unit on the prevention and treatment of chronic skin ulcers (pressure ulcers) to support the development of educational content. The development of an educational content about pressure ulcers used the Planning Learning Activities Supported by Computer based on the concepts of the Theory of Meaningful Learning. The course about prevention and treatment of pressure ulcers was created in the virtual learning environment Moodle, using as a structure a division by chapters and consists of an introductory text, introductory exercises, revealing the knowledge (educational content) and the full text. In addition, a glossary, chat, discussion forums, course evaluation, recommended links, notice board and contact have been used as tools. In the final step of this study was made an assessment of educational content for expertises in the nursing subject and distance education. In the assessments were highlighted by all the evaluators the scientific rigor and update of the course available. Also identified some areas for improvement, as increase interactivity with the student and improve the quality of the images presented. This work was possible to verify the importance of information technology for the development of distance education courses for nursing and health education, and the importance of researches about skin ulcers. We identified that the creation of courses with the help of a multidisciplinary team is a strategy that we must use, searching with this the creation of interactive courses with the students, providing greater adherence and understanding of the material provided. We 11 conclude that despite the continued growth of distance education, several investments are still needed to reach the same one of its purposes that is to expand the science education.

Cette thèse cherche à éclaircir le sens général de l´ontologie merleau-pontyenne, telle qu'elle se présente dans la Phénoménologie de la perception. Nous analysons d´abord la naissance du projet ontologique de Merleau-Ponty dans le contexte de la première partie de sa thèse de doctorat, La structure du comportement. Ensuite, à travers une analyse de l´introduction de la Phénoménologie, nous soulignons la nouveauté ontologique de la forme perçue (Gestalt) par rapport aux conceptions empiriste et intellectualiste de la perception. Au troisième chapitre, nous essayons de montrer les contours que prend le retour phénoménologique aux choses mêmes sous la plume de Merleau-Ponty. Le quatrième et dernier chapitre examine l´articulation entre l´empirique et le transcendantal dans la Phénoménologie de la Perception, telle qu´elle se révèle dans la formulation de la thèse merleau-pontyenne de la fondation des relations expressives à partir de la compréhension de la temporalité comme mesure de l´être.

This dissertation presents the results of an investigation that aimed at verifying the effects of teaching-learning grammar as skill on accuracy of young learners attending a course based on four different themes. Besides being thematic, the course design followed the grammar as skill approach and theory to guide the activities and the development of the classes. Based on qualitative data analysis, we present the results of our study, which reveal students involvement and accuracy progress when exposed to meaning-focused formal language studies. Students proved able to notice language aspects, structure and use them in verisimilar contexts, specially concerning grammatical and linguistic aspects that had been focused in classes. We have based our discussion and pedagogical activity design mainly on Batstone (1994) and Larsen-Freeman (2004). The activities proposed in the course that has served as the context for data collection are available at the appendix section of this dissertation. Our research is likely to contribute with the discussion considering the role of grammar teaching in classrooms as well as to provide professionals in the area with a better comprehension of this contemporary approach, which has not been widely investigated yet.

The present work aims to elaborate an acquaintance about the social and spatial inequalities still few studied in non-metropolitan urban realities, specifically in small towns. Therefore this dissertation attempts to weave some considerations about the production of urban spaces in São Paulo small towns, examining the practices and actions of the producers agents of the urban space, which contribute to an unequal and excluding social-spatial formation, making a reflection from a study case in Capão Bonito, Buri and Ribeirão Grande, in order to achieve an analysis that allows to understand how public and private spheres and the civil society contribute in different ways to the unequal production of urban spaces, seeking to identify, in different perspectives, how exclusion is manifested in these urban realities. Thus, we seek to contribute to a deeper theoretical understanding of excluding processes in small towns in São Paulo State. The concept of spatial deconstruction is used as an analytical instrument to interpret space production and this research was made feasible by a bibliographic gathering, fieldwork and collection, data analysis and systematization that allowed a spatial reading of exclusion to indicate in different perspectives, how the phenomenon manifests itself both in the intra-urban scale and in the intercity scale. For this purpose we seek to contextualize the small towns from the economical aspects linked to the urbanization process, through what is possible to verify the constitution of Brazilian urban network guided by the competition between cities. Then reflect if the small towns, in this context, are excluding territories and emphasize the importance of thinking about solutions, mainly in territorial management and integrated urban network, turning possible to minimize the socio-spatial inequalities that afflict small towns.

Our research aims to analyze the discursive construction of ethos in the discourse of the indigenous teacher, seeking to understand how discursive practices historically stereotyped by non-Indian determine the images, the ethos that the subject "Indian" professor constructs himself in the discourse intended for educational training indigenous trainers. We work with the hypothesis that the discourses produced by the indigenous teachers textbook for training of Indian students, the Other constituent of his speech is his pocket, his neighbor, on the contrary is non-Indian who live a conflicted relationship since that the Portuguese landed in American continent in 1500. From this perspective, we take as theoretical and methodological discourse analysis of French oriented, highly nuanced by pecheuxtianos and maingueneanos tones. The empirical corpus mobilized for this research consists of the book O índio brasileiro: o que você precisa saber sobre os povos indígenas no Brasil de hoje (The Brazilian Indian: what you need to know about indigenous peoples in Brazil today) volume 12, which includes the series Vias dos Saberes (Ways of Knowledge) Coleção Educação para Todos (Collection Education for All), written by the Indian Baniwa whose goal to provide subsidies for training of indigenous students in undergraduate courses in intercultural level. Our analysis indicates that the image of discursive enunciator / Indian is a militant and his discourse is overlapped by the discourse of the non-Indian in a relation conflicting and nomad.

The present work has the objective to contribute with the quarrel on the support of Brazilian familiar agriculture, by means of the reconstruction of the trajectories of transition of familiar producers and the identification of social pointers of support, based on participative principles. The case study it was carried through in the agricultural community of the Verava, city of Ibiúna/SP, where familiar agriculturists had adhered to the way of production of ecological base, motivated for the necessity of improvement of the income conditions. To understand this process it was integrated, in the analysis, the vision of the agriculturists of the searched universe. Such boarding allowed to catch the dynamics, the moment-key of the transition process, the advances and the challenges in the scope of the local development; it brought to elements that they make possible to evidence that the agriculturists had had similar sociocultural contexts and few variations in the productive structure and the familiar logics. One concludes that the trajectories of transition and the pointers of support are influenced by the professional experience, cultural patrimony, public politics, type of social organization and type of insertion in markets, influencing the quality of life of the agriculturists and local social justice. E the research generated a set of knowledge that will be able to serve of subsidy for the formularization of public politics.

The word assessment has different meanings and it has no difference when we think of the act of evaluating in the educational context. It can be used as a means of classification, exclusion or as a very useful tool in the teaching-learning process. This work is a case study that has as a landscape a particular subject in the Physics Course of a Public University in Sao Paulo State and the subjects are its professors and students. This study, presenting as methodology the approach of a study-case, has different collect tools and it shows the relationship between assessment and the teaching-learning process by diverse perspectives. Two important conclusions can be drawn from this study: the first one is that the educator s conceptions of assessment and the teachinglearning process have a direct influence on the relations that will be established within the assessment along the subject teaching. The university context brings up some particularities and the university educator is set aside in this study-case. The second important consideration is the way that the study approaches the teacher and it can discuss about issues related to content s pedagogical aspects, a way to achieve the university educator.

In this work we present a bayesian approach for the survival model with cure rate in the presence of covariates. In this perspective, the modelling is a direct extension of the long-term model of (Chen et al., 1999). This model is considered flexible in the sense that the effects of the covariates are measured locally using the bayesian partition model developed by Holmes et al. (1999). The bayesian partition model is a generic approach to problems of classification and regression where the space of covariates is divided in disjoint regions defined by a structure of tessellation. The extension to modelling local maintains the structure of the proportional hazards model that it is intrinsic of the long-term model(promotion time) (Rodrigues et al., 2009a). Application of this theory appears in several areas, for example in finance, biology, engineering, economics and medicine. We present a simulation study and apply the methodology to a set of data on the clinical studies.

In this work bilayered electrodes made of polypyrrole Ppy and poly(2,5-dimercapto-1,3,4-tiadiazol) poly(DMcT) were produced and characterized on carbon-fiber substrate. To do so, several aspects were investigated: effect of the charge growth (1, 2, 5 and 10 C) on the electrochemical and morphological properties of Ppy electrodeposited on carbon fiber; definition of a growth charge/mass ratio for the Ppy film, leading to a high electrochemical performance electrodes with a stable specific capacity; proposition of an optimized methodology to prepare, by electrochemical means, bilayered composites of Ppy and poly(DMcT) on carbon fiber substrate. All materials had their morphological and electrochemical properties analyzed by means of scanning electron microscopy, cyclic voltammetry and impedance spectroscopy. Thinner Ppy films presented the higher coulombic efficiency and specific capacity values. Electrochemical impedance results indicated that Ppy catalyses the redox reactions of poly(DMcT), allowing its use in secondary batteries. Galvanostatic charge and discharge tests from either thin Ppy film and poly(DMcT)/Ppy (1 C) bilayered film electrodes resulted in excellent performances when used as lithium ion battery cathodes (130 and 300 mA h g-1, respectively) or electrochemical capacitor electrodes (240 and 500 F g-1, respectively).

This work analyses the factors that could influences the Chemistry learning. The motivation is considered a fundamental construct for the scholar learning. The motivation is related to internal or external causes that lead an individual to accomplish or not an activity. Those internal and external causes are denominated intrinsic and extrinsic motivation, respectively. Intrinsically motivated students engage in the accomplishment of scholar activities and incline to persist in front of difficulties. Opposite behavior is observed in extrinsically motivated students. 389 students were invited to participate to a course about Metals. 74 have done the registration in the course and 20 registered students have done the course. Data were collected by questionnaires to delineate the motivational profile of the students. The questions were focused on the identification of the motivational orientation of the students. During the analysis of the questionnaires were observed that the students who have not done the registration present less positive motivational profile to the scholar activities than those who have done the registration and those who have participated of the course. Therefore, independently of type of the motivation, intrinsic or extrinsic, the students that demonstrated interest to the course are more motivated to the scholar activities. However, during the course, were observed differences between students. Some engaged yourselves actively and others, mainly in the moments that the activities demand more attention, engaged yourselves superficially. This difference can be related to the type of motivation. Students with intrinsic motivation more positive than extrinsic engage yourselves more in the proposed activities than students with predominant extrinsic motivation. This research allowed verifying that the motivation is related to contextual factors and the characteristics students and this fact must be considered to better comprehend the behavior of classroom students. Some leaning strategies support the occurrence of motivational orientations that will generate different levels of interest to the realization of the activities. However, when significant learning are considered, environments that support the occurrence and maintenance of intrinsic motivation are considered more adequate.

This research project on the plans of the new campuses for Brazilian public Universities aims to discuss the urbanistic proposals used in four different plans in the state of Sao Paulo. This work attempts to evince which concepts were adopted in these projects, taking into account the national context, at the beginning of this century, of expansion, creation and restructuring of new campuses for public Universities and the relevance that this urban equipment has because of its social function and dimension. As theoretical foundation, we present a survey of historical moments that are of major concern for the apprehension of the research object. To this end, we approach initially the birth of the first University in Europe and the emergence of the campus in the U.S.A. Then, dealing with the history of Brazilian Universities, we highlight the development process of the campus, taking into consideration that the beginning of its implementation is an essential and paradigmatic phase. In order to discuss the proposals for the four new plans, certain categories of analysis were established, which focus on: an analysis of site where the campus is placed, the identification of urbanistic concepts, the parameters and guidelines for urban design, the verification of the road system, a spatial analysis of buildings and the open area and, finally, environmental sustainability a current theme present in disputes on planning. By means of systematization of the collected data, we sought to identify the urbanistic performance and the similarities and differences between the plans. Various issues were found in the specificities of each plan, such as the production of spaces that meet the new pedagogical proposals, the appreciation of the collective use of spaces for both convivence and learning, the promotion of environmental sustainability and the accessibility and mobility on the campuses, which demonstrates that there is an intent to match the demands generated by contemporary society.

The process of urban progress, cause the disordered regions growth with some or without structure. In case of school's location, this process can generate excess of school places in some regions while in others there is a de_cit, thus subjecting the students, in some cases, the displacement of several hours. Trying to solve these problems, governments have been investing in programs such as _nancing school transportation, for the conduct of students from more remote regions. This study examined the spatial distribution of public schools comparing with the level of income, education and age of the population, using GIS techniques associated with Knowledge Extraction from Databases (Data Mining). This practice allows for the discovery of hidden information in large databases that may be considered interesting, as you con_rm, extend, or challenges the existing knowledge on the subject. Additionally, it allows a more elaborated on the educational services provided, given the existing demands, contributing to a critical analysis of the situation of these towns, in educational point of view, searching the assignment of a better quality of life for people. The city of Araraquara-SP, is a medium size city, and considering the availability of data and the importance for future applications of the results extracted, was chosen as the object of study. This study used techniques of Spatial Data Mining, allowing the discovery of important information, such as the fact that poor people reside far away from public schools. Besides, the analysis of the data presented de_cit and bad distribution of high schools in the city of Araraquara. These evidences indicated the feasibility of the methodology used also for large databases.

The endophytic microorganisms Penicillium griseoroseum, Penicillium brasilianum, Aspergillus flavus e Aspergillus aculeatus have shown to be very efficient in order to perform the most diferenciated biotransformation reactions. The fungi Penicillium griseoroseum has presented an elevated desmethylation selectivity of the caffeine substrate besides the desmethylation of the 2 ,4 ,6 - trimethoxyacetophenone. More complex chemical modifications as the formation of the C-C bond (in the flavanoid 5,7,3 ,4 ,5 -pentamethoxyflavanone) and chloration were also observed with this microorganisms. Yet when explored with flavonoids such as the naringenin and hesperetin, their respective chalcone and, with the glicosylated flavonoid the fungi has also shown itself active. Besides that, the oxidative capability of the Penicillium brasilianum e Aspergillus flavus fungi has been explored with the 1 indanone substrate. Both fungi have performed the Baeyer-Villiger oxidation reaction and the hidroxylation as well. Therefore, when testing glicosylated flavonoids with the fungi Aspergillus flavus their complete degradation was obtained, but with the respective methoxylated substrates no transformation has been obtained. The Aspergillus aculeatus fungi was explored concerning its capability of dimerizing substances. This way, the used substrates were the phenolics 2-naphthol, 1-naphthol e 1- naphthilamine compounds. As a biotransformation product a new reaction was obtained, a Fries rearrangement that has originated the adition of the ketil group to all tested substrates.
