    This work focuses on the State of Espírito Santo in the 30 and 40 decades in the 20th century and aims to analyze the conflicts that took place in the meeting of two relevant events of this period: the repression to the Integralism and the consequences of the Second World War. It is important to stand out that the State of Espírito Santo, as well as other Brazilian States, had its history marked by European immigration in the 19th century. At that time the state received, mainly, Pomeranian/German and Italian immigrants. Part of these immigrants and descendants, in the decade of 30, acted in Brazilian Integralist Action (AIB), a right extreme party and influenced by European Nazi-fascism. Some conflicts that imbricated ethical issues and the acting of AIB, officially forbidden since the coup of the New State, became more visible and resulted in criminal proceedings. It was ascertained that AIB had strong presence in Espírito Santo, especially, in the regions of Pomeranian/German and Italian settlement. Also, it was verified that ethical conflicts did not seem to be so prominent as it was expected to. It seemed that the major conflicts were marked by a nationalistic feeling and confrontations that still had AIB as an explanation. It can also be suggested that differentiated cultural practices of the immigrants and descendants were not understood as so dangerous by the government since they were followed of economic and politic status, for instance, case of the South of Brazil. Originated criminal proceedings in the State of Espírito Santo, which were presented at the court of National Security (TSN), were used as privileged sources. Some paper was analyzed such as: documents and photographs apprehended by the Espírito Santo police from AIB nucleus, official letters from the Education and Justice department, newspaper and magazines, besides interviews with inhabitants of Domingos Martins city (ES). The historical event reported starts with AIB National Congress in Vitória (1934) and it closes up with the Second World War end (1945). Key words: Brazilian Integralist Action. Second World War. Immigrants. Criminal Proceedings. National Security Court.

    The main objective of this study is to analyze the factors that explain the reactions of the opposition sectors to the government of Hugo Chávez between 2001 and 2004. The understanding of these reactions is searched having as background the break with the liberal democratic regime occurred in 1999, with the up rise of this president, inaugurating what it calls democracia participativa y protagónica . To achieve its objectives this work try to understand initially the political regime in the country since the construction of liberal democracy around the Pact of Punto Fijo, through its crisis during the 1980s, until the election of Chavez in 1998. Finally, we present some interpretations on the political and institutional changes occurred with the new government and what they may represent in the sectors linked to the former regime that arise in opposition. The findings indicate that the reactions of these sectors to the government initiated in 1999, resulted from its displacement from the power, and not as they stated in their dissatisfaction with the "authoritarianism" of the new regime. What they pursued was the control of the state, allowed by the minimalist nature of democracy pre-Chávez.

    This dissertation reports an approach to enhance information retrieval systems which are accessed through mobile devices. This sort of devices can impose constraints on user-computer interaction, mainly concerning expression of contextualized queries and navigation of long lists of results. Our approach integrates user work context in implicit relevance feedback, which is developed over a Case Based Reasoning methodology, with the purpose of providing personalized information retrieval. To tackle these issues, it was developed an architecture to manage transformation and processing of context information, as well as selection of evidences to expand queries through implicit relevance feedback. The project was evaluated on two case studies and the obtained results show that our approach enhances the quality of information retrieval, even under varitions on the size of the document collection, on the diversity of users and on context situations.

    It is estimated that in Brazil one of 500 children have low vision. In this population, among all difficult possible, have the dependency in daily life activities (ADL), that influence at social integration, learning and school inclusion. Detached for the regular teacher s work inside the class with ADL´s children especially in preschool. The propose of this work was to develop, implement and evaluate one individual program of collaborative assessoring in Occupational Therapist for teacher training, to increase their repertoire of strategies and resources to promote the independence of preschool children with low vision in activities of daily hygiene and nutrition, called PRÓ-AVD . Study participants were 10 teachers and 10 students with low vision aged between 4 and 6 years of regular education children. The experimental design of the study consisting of 5 teachers and 5 students belonging to the Experimental Group who received the intervention in a first moment, and 5 teachers and 5 students to the control group that received no intervention. The elaborate of the training program involved the study of children's abilities in the tasks of self, and his visual capacity, the original repertoire of the teacher, and the dynamics of dyad Teacher - Student in carrying out AVDs. The implementation happened through collaborative assessoring, on 6 weekly meetings, consecutive, consisting of interactive dynamic between the researcher and teacher. Measures were taken pre-test and post-test and a field diary, analysis of film and questionnaires to assess qualitatively and quantitatively the effect of the intervention program in increasing the repertoire of teachers to promote the independence of their students in AVDs. The program showed efficient when applied, the results were increasing her preparation and teacher repertory to work with hygienic and alimentation activities of the student with low vision. It is believed that the use of methods and teaching approaches, practice activities, feedback and support of researcher presence than weekly meetings were crucial to the membership and participation of teachers, as well as to obtain the results.

    The following work has as main purpose discuss the present public politics of urban environmental management by analyzing municipal models, practices and experiences, in search of an absolute management. Inside the thematic of environmental and urban institutional politics, dialoging with normative aspects, of planning and institutional management, this research seeks the understanding and the analysis of the urbanenvironmental management from the city councils of Araraquara and Santo André. The selection of these city counties parted from the observation that they are in a favorite position in comparison with other ones due to the operational, administrational and cultural circumstances respecting to the new demands from the National System of Environment. In parallel, this research will board the difficulties of these both city counties to attend the new establishes that are being placed to them since the redemocratization of the 80´s, with regard to the municipal urban-environmental management, as well as to the questions associated with the interface between the urban politics and the environmental politics.

    For some applications toughening of polyamide is important. This can be accomplished through the addition of an elastomeric phase to the polyamide matrix with the drawback of a reduction in the stiffness and strength of the material. Several studies lately have focused on the modification of polyamide matrix with the purpose of obtaining a balance between toughness and stiffness for these thermoplastics. In this work, to achieve a balance between stiffness and toughness, ternary nanocomposites based on blends of polyamide 6 (PA6) and acrylonitrile-butadiene-styrene (ABS) were prepared by the melt blending processes using the organoclay Cloisite® 30B (OMMT) and the styrene-maleic anhydride copolymer (SMA) as compatibilizer. Four blending sequences were used to prepare the selected systems and their mechanical properties studied through the Young s modulus and notched Izod impact properties. The addition of organoclay increases the Young s modulus of all ternary nanocomposites when compared to the blend and the PA6 matrix. This fact was attributed to preferential location of the clay in the PA6 matrix phase. The micrographs obtained by transmission electronic microscopy (TEM) indicate that the nanoclay shows an exfoliated structure and reside in the PA6 matrix phase, as well as in the interface between the phases. PA6/ABS/OMMT ternary nanocomposites with different content of nanoclay (1, 3 and 5%) were studied and it was observed that the particles size of ABS dispersed phase decrease with the increase of the OMMT content in the blend. This fact indicates that nanoclay can play an important role to prevent the coalescence in the ABS domains during the melt state processes. PA6/ABS ternary blends compatibilized with SMA were prepared by melt state process and it was observed that the mechanical properties and the morphology were influenced by the blending sequence of the components.

    Geographic Data Warehouses (GDW) became one of the main technologies used in decision-making processes and spatial analysis since they provide the integration of Data Warehouses, On-Line Analytical Processing and Geographic Information Systems. As a result, a GDW enables spatial analyses together with agile and flexible multidimensional analytical queries over huge volumes of data. On the other hand, there is a challenge in a GDW concerning the query performance, which consists of retrieving data related to ad-hoc spatial query windows and avoiding the high cost of star-joins. Clearly, mechanisms to provide efficient query processing, as index structures, are essential. In this master s thesis, a novel index for GDW is introduced, namely the SB-index, which is based on the Bitmap Join Index and the Minimum Bounding Rectangle. The SB-index inherits the Bitmap Index legacy techniques and introduces them in GDW, as well as it enables support for predefined spatial attribute hierarchies. The SB-index validation was performed through experimental performance tests. Comparisons among the SB-index approach, the star-join aided by R-tree and the star-join aided by GiST indicated that the SB-index significantly improves the elapsed time in query processing from 76% up to 96% with regard to queries defined over the spatial predicates of intersection, enclosure and containment and applied to roll-up and drill-down operations. In addition, the impact of the increase in data volume on the performance was analyzed. The increase did not impair the performance of the SB-index, which highly improved the elapsed time in query processing. Moreover, in this master s thesis there is an experimental investigation on how does the spatial data redundancy affect query response time and storage requirements in a GDW? . Redundant and non-redundant GDW schemas were compared, concluding that redundancy is related to high performance losses. Then, aiming at improving query performance, the SB-index performance was evaluated on the redundant GDW schema. The results pointed out that SB-index significantly improves the elapsed time in query processing from 25% up to 99%. Finally, a specific enhancement of the SB-index was developed in order to deal with spatial data redundancy. With this enhancement, the minimum performance gain observed became 80%.

    Applications with time restrictions are becoming common in our daily lives. These applications range from games to applications for controlling air traffic. Applications with time restrictions that use the Internet / Intranet as a mean of communication (e.g. streaming audio and video, VoIP and messaging PRC-RT), require that their packets be delivered before the end of its deadline. In these cases prioritize traffic from the packets generated by these applications in relation to the other packets is a way of trying to minimize the loss of deadlines. Thus this work presents an architecture of gateway with QoS and traffic forecasting that aims to focus on requests from time-restricted applications. Gateway classifies traffic based on the IEEE 802.1q standard, in six classes with different priorities and uses the Box-Jenkins mathematical model to predict the amount of traffic for each class of service and provide resources to meet the classes according to their priority.

    In this thesis, the results regarding the investigation about the cobalt electrodeposition in templates of porous anodic alumina are presented. The doctorade is divided in four main sections. The _rst one has consisted in exploring many experimental set up to the preparation of porous anodic alumina using galvanostatic mode. The main results are related to the high ordering achieved using the galvanostatic mode and the sistem versatility concerning preparation of new architectures in porous anodic alumina such as the two overlapped porous layers presented in this thesis. The second part is about the computational study of the metalic electrodeposition in porous templates. In this step a bidimensional model to the metal electrodeposition in porous sistem was developed and simulated. The model considers one potenciostatic pulse. Potential distribution inside the template is calculated using the Laplace equation. Difusion equation takes into account the transport of electroactive species. Simulations show clearly the interaction between the concentration gradient inside the pore and potential distribution in the oxide inner. This dynamic allows to understand the top deposition and is consistent with the catch up e_ect. Based on insights from early step, the cobalt electrodeposits in porous anodic alumina were prepared by galvanostatic and potentiostatic pulsed electrodeposition. Finaly, the fourth part of the work deal with the magnetic characterization of the cobalt electrodeposits. The electrodeposits prepared by galvanostatic pulsed electrodeposition presented the exchange bias behaviour. The exchange bias is result of the presence of antiferromagnetic cobalt oxide, which lead to the formation of ferromagnetic (Co)/antiferromagnetic (CoO) interfaces responsible by the increase in the coercive _eld when the sample is cooled at presence of high magnetic _eld (Field Cooling procedure - FC). In addition, it was observed a anomalous temperature dependence of coercive _eld. Regarding the electrodeposits prepared by potentiostatic pulsed electrodeposition, they showed similar temperature dependence of coercive _eld. The coercive _eld (HC1) increase as the temperature is reduced from 300 K, achieving a maximum around 100 K, and from this point, the coercive _eld decrease signi_cantly. According to the reversible magnetic susceptibility behaviour, this result is related to the magnetoelastic contribution to the sistem anisotropy.

    This research aims to characterize the incidence and development of major pests and diseases of coffee in agroecosystems under conventional, organicmineral, organic and agroforestry managements in two municipalities in the southern Minas Gerais State: Machado and Poço Fundo. It was carried out monthly monitoring of the leaf-miner (Leucoptera coffeella), borer coffee (Hypothenemus hampei), rust (Hemileia vastatrix) and brown eye spot (Cercospora coffeicola) for a period of one year (december/2007 the november/2008) in crops of Novo Mundo variety with spacing (3.0 to 3.5 m X 1.0 to 1.2 m). The monitoring of leaf-miner and diseases of the coffee was done through the collection of ten sheets of the third or fourth pair in all sides of the coffee, and twenty plants sampled by agroecosystem, totaling two hundred leaves collected for evaluation of pests and diseases in each system. To monitorate the borer coffee it was selected 32 plants, six different points on each plant (10 fruits grouped by set point) and there was non-destructive evaluation. In all agroecosystems monitored, both managed by the family farm, the infestation of the borer coffee and leaf-miner did not reach level of economic damage in any evaluation. With respect to diseases evaluated, it was observed that the rust and brown eye spot reached the level of economic damage in all management systems. However, the organic-mineral systems, organic (monoculture) and agroforestry (organic) the occurrence of rust was critical to reach high levels in the months april to october of 2008, and the values above 60% of incidence in four months of evaluation. The incidence of brown eye spot was relatively lower in the conventional and organic (monoculture), whose peaks did not exceed 41% and 55%, consecutively. Already in the organicmineral and agroforestry (organic) the occurrence of Cercospora reached very high levels, reaching 76% and 67% respectively in July. Despite the high incidence of rust and brown eye spot found in coffee agroecosystems organicmineral and organic, the average productivity achieved by these systems in the past three years was higher than the conventional, even the latter system investing heavy in pesticides and chemical fertilizers.

    In Hydraulic and Sanitary Building Systems there are nonconformance issues that can occur when user begins occupying and interacting with the building. Among other systems, the Hot Water Building System is responsible to offer to user important activities to human being such as bath and dish washing. The performance of the systems that constitute the housing buildings along its life is connected to the conditions of use for it was designed, to the execution of the construction according to the technical regulations, to the use of materials and components free of imperfections and to the programs and techniques of regular auditing and building maintenance. Even though the field of nonconformance is a subject not so explored in Brazil, it can be inferred as causes of nonconformance issues in the Hot Water Building System: technical regulations out-of-date, project mistakes, inadequate specifications, manufacture problems, execution errors, lack of maintenance or inadequate maintenance. This dissertation, based on the user's requirements as established by NBR 15575-1, objects the identification of performance requirements and criteria, to multistoried residential buildings. This theoretical study was applied to two multistoried residential buildings to find out probable s nonconformance.

    This work is aimed at studying slab systems for steel structures by assessing massive conventional slab, framed slab, pre-cast slabs, compsite slab systems and other systems of steel and concrete. Characteristics as well as structural and building advantages and disadvantages of each slab system for steel structures usage are addressed. Based on a defined architecture, a structural project will be developed in which the main structure (columns and beams) is supported by steel structure, and several solutions using different slab systems will be technically presented according to the methodology for mounting them, execution, and cost comparisons. A more realistic evaluation of each slab system studied was sought by comparing them to each other in terms of structural behaviour, building techniques, and cost.

    Aiming at improving competitive advantage, organizations in general have been giving more attention to knowledge engineering, as well as its techniques and methods to acquire and represent knowledge already in place. This knowledge is sometimes not fully explored, or not explored properly. This approach is to develop a knowledge modeling strategy for reactive production scheduling, which focuses on tacit and explicit knowledge acquisition and representation. The knowledge representation aims at getting results closer to the organization reality and should also be comprehensible and easy to be validated by experts. To validate the proposed model, a computational system was developed to evaluate the model behavior under a specific domain, as well as to verify if the results are satisfactory. The model supports decision-making when unplanned events occur during the production process, enabling the possibility of evaluating greater knowledge to make the decision and also allowing the operator to make the decision without any expert support. The validation was performed in two steps; the first one, the computational system validation, was carried out by unit tests on every module, and after that, an integration test was performed. The second one, the proposed model validation, was verified in two ways. The first one was the validation using the industry use cases based on industry platform existing in the TEAR laboratory; the acceptance and understanding of the models by experts were verified using the same models already validated in a project between an industry and the TEAR laboratory.

    The aim of present work was developing nanocomposites of polypropylene (PP) with organoclay (MMT) in the presence of a compatibilization agent (PP-g-MA) in the melt state. The masterbatch of PP-g-MA and organoclay was prepared in a mixer with high shear rate and then cryogenically frozen and ground. The nanocomposites were prepared with 1.5%, 2.5%, 5% and 7.5% (w/w) of organoclay into PP in a twin screw extruder. In the all case it was maintained the ratio of 1:3 organoclay/PP-g-MA. The morphology and structure of the nanocomposites were evaluated by their thermo-mechanical properties, tensile strain and permeability to water vapor and oxygen. The analysis of XRD showed a marked decrease the in peak intensity referring to the pure organoclay for all nanocomposites. The SEM / FEG micrographs revealed the morphology of the surface for all sample. It was observed the complete dispersion of organoclay into polymeric phase and the structure seen was like a rod with some mixed clusters. While the micrographs of TEM showed the formation of nanocomposites with high intercalation for 1.5% and 2.5% of organoclay. The TGA analysis demonstrated an increase in the temperature of degradation (2% loss of mass) of 29°C for the sample of 1.5% of organoclay. The DSC curves did not show any influence of organoclay in the values of Tf for ΔHf and nanocomposites. The DMTA analysis showed an improvement for all parameters examined (on the storage modulus, change the temperature of phase transition α 'and HDT) once more for the sample of 1.5% of organoclay. The permeability to water vapor was effective, especially for the sample of 1.5% of organoclay, where the reduction was of 43% lower than extruded PP. However, the permeation of O2 didn t present the same improvement for the nanocomposites studied in comparison to the water vapor permeation.

    A preliminary genetic linkage map was constructed for the species Prochilodus argenteus, an endemic fish from the São Francisco river basin, using 23 microsatellite markers in a progeny with 95 individuals from a single cross by the pseudo-testcross strategy. The male and female parents were collected in different regions, downstream of the dam of the Três Marias (MG). Only 11 (52.4%) markers grouped in some linkage group and the the remaining was unlinked. Twenty-one (91.5%) markers appeared to segregate according to Mendelian inheritance, and only two (8.7%) showed segregation distortion. The map covered 297.58 cM of the genome, according to the Kosambi s function. The number of linkage groups (3) found in this study was much lower than expected for the species (equivalent to the haploid number of chromosomes, n = 27), demonstrating the importance of using a larger number of molecular markers in future studies. The data obtained in this work will be compiled with the marks obtained by AFLP by Rojas (2008) in order to obtain a denser genetic map. Although the number of linkage groups found have been lower than expected for the species, the results can be considered promising for the Brazillian Fish Genetics, since genetic mapping studies are virtually absent in Neotropical fish.

    Based on the assumption that supervised internship is an important part of a teacher s education, this work sought to identify what are the possible relations/influences of mathematical modeling on the internship activities of a future mathematics teacher. A qualitative research was carried out in a public state school in the city of São Carlos and included the participation of two students of an Undergraduate Mathematics course (Teaching License). While these students were attending the subject Supervised Internship in Mathematics in Elementary Education 2, they joined the author of this research to design three projects of mathematical modeling for seventh-grade students. In the case study, the trainee teachers applied all the three projects, what resulted in an empirical material consisted of audio interviews with the trainee teachers, videos of the classes, documents produced by the seventh-grade students, and documents produced by the trainee teachers (field journals, reflective journals, and reports of the internship). The theoretical basis included works by Tardif (2002) and Mizukami (2004) for understanding how the teacher learning takes place, as well as works by Moura (1999) and Pimenta (2004), which contributed to the understanding of the supervised internship as an environment of teacher knowledge, while the studies by Borba (1999), Biembengut (1999) and Barbosa (2001c) allowed the construction of a concept on the use of mathematical modeling in Mathematics teaching. The focus of investigation was the way the trainee teachers acted in the supervised internship while developing projects of mathematical modeling. The idea was to analyze which types of knowledge, conflicts, and reflections they build in such process. The research showed both the potential of mathematical modeling being used in initial education as part of internship activities when undergraduates take their chances on their first experiences as teachers and the production of teacher knowledge.
