Structural analysis of framed structures using discrete method, wherein, splitting them into elements with simplified considerations, can bring not satisfactory results or end up using very high safety coefficient to the structure. With the growth of computing and microcomputers it is feasible the resolution of structures considering all parts, therefore three-dimensional. The scope of this work is to make a physical and geometrical non-linear analysis of three-dimensional framed structures with re-bar elements, which can be joined by monolithic or semi-rigid connection, that is commonly used in Precast concrete structures. In order to reach this aim, has been developed a free software using PASCAL language and structural matrix analysis, adding up concrete physical nonlinear analysis with Branson expression. The geometric non-linear was considered from a present Lagrangean formulation. In both cases, it was used the incremental loading technique, which showed a very interesting relation between the results. In order to consolidate the studied concepts and to validate the developed software, it was dedicated a special attention to the resolution of several samples, comparing them with the given results of other software and also with values from experimental analysis, specially for the semi-rigid connections

One of the key points in steel development has been the refinement of the microstructure, however without change the chemical composition with addition of alloy elements. The refinement of the ferrite grain size leads simultaneously to an increase in strength and toughness. Ultrafine grains can be produced through thermomechanical controlled treatments, generated by dynamic strain-induced phase transformation (g®a), which also can be associated with others dynamic phenomena, such as dynamic recrystallization. In this work a low and a middle carbon steel were previously austenitized at 900ºC for 180 s and cooled at 1ºC/s to a given deformation temperature established in relation to their critical temperatures. The deformation were applied with a strain of 2,5 at a strain rate of 1 s-1. The behavior of the materials during the deformation was analyzed using the stress-strain curves obtained from torsion experiments. After deformation, the samples were air cooled and the final microstructure characterized by scanning electron microscopy. It was determined with success a route capable to produce ultrafine ferrite grains, where grain size of 1,6 μm were produced for the Cos Ar 60 steel and 1,3 μm for the SAE 1548 steel.

Ceramic samples are efficiently digested using fusion procedures. However the elevated amounts of dissolved solids in the resulting solutions may cause spectral and transport interferences, affect the analytical blanks and background signals and consequently the limits of detection. These effects can be even worst when measurements are performed using ICP OES with axial view configuration. Therefore, the goal of this thesis was an evaluation of the feasibility of application of an ICP OES with axial view configuration for determination of analytes in complex inorganic samples digested by fusion. The proposal was based on the suitability of fusion procedures for fusion of refractory samples and, on the other hand, the susceptibility of the axial configuration to spectral interferences and effects caused by high concentrations of dissolved solids. The study was carried out using standard reference materials of bauxite, refractory, silicon carbide and glass that were fused using Na+ and Li+ fluxes. All analytes were determined using selected ionic and atomic emissions lines in solutions containing 0.1, 1.1 and 2.2 % m/v of dissolved solids. The instrument was calibrated using analytical solutions prepared in acid or in the reagents media. The ICP OES parameters were optimized in order to obtain robust and non robust conditions according to the Mg II / Mg I ratio. The limits of detection, dynamic linear range, and sensitivity were established. Despite the complexity of the samples, suitable results were obtained for all of them. The most critical aspect was related to the quartz torch lifetime and it was not possible to introduce solutions containing 2.2. m/v of dissolved solids. The deposition of solids in the quartz torch was minimized by increasing the flow-rate of the auxiliary gas to 2.25 L min-1. Severe matrix effects were not observed in robust and non robust operating conditions (recoveries were around 100 + 20 % for minor elements and 100 ± 10 % for major elements). Finally, this research led to the establishment of analytical procedures for each sample material. The best experimental conditions were those that allowed the determination of most analytes in the same sample solution taking into account the multielement capacity of the ICP OES.

Electrochemical sensors provide real time information of chemical compositions of molten metal. They can be used to improve the control of various metallurgical processes. One of the most successful and widely used electrochemical sensors is the oxygen sensor, based on zircônia solid electrolyte, usually used in steel making. Sensors are being developed for measurement of other chemical elements, but it is very costly and complicated to be produced. In order to solve this problem, in this work synthesis and assembly of β-alumina and β-alumina based on solid electrolyte sensors were studied. For this, the phase of interest was prepared by the mixing of oxides, and characterized. Traditional ceramic forming processes, isostatic and slip casting, were used to produce the prototypes and their ceramic characteristics were evaluated. Both compositions did not present high density after sintering at 1600°C, reaching 90% theoretical density. This fact could be responsible for the break down during the application of the sensors. The Na-β- alumina sensor produced did not present a satisfactory performance for measuring the dissolved sulphur in liquid pig iron. On the other hand, the β-alumina sensor, despite of the secondary phase, showed good behavior in terms of response time (between 5 and 8 seconds) for measuring the dissolved sulphur in liquid pig iron at temperatures from 1440°C to 1460°C, with La2O2SO4 auxiliary electrode and three different reference electrodes. The signal response of EMF between 54 mV and 174 mV was measured in a measuring level from 32 ppm (weight) to 432 ppm (weight) of sulphur dissolved on the metal bath

Alkaline baths containing sorbitol, tartrate or EDTA were developed in this work for Pb-Sn and Pb-Cu electrodeposition on platinum substrate. The characterization of Pb-Sn and Pb-Cu plating baths by potentiometric titration showed the pH when the species of metallic ions were soluble and stable. The voltammetric curves obtained from these baths indicated that the complexation of metallic ions by sorbitol, tartrate or EDTA, had a beneficial effect, since closed the deposition potential these metallic ions, leading to codeposition of Pb-Sn and Pb-Cu. The analysis of the Pb-Sn and Pb-Cu deposits by x-ray dispersive spectroscopy showed that codeposition of Pb-Sn or Pb-Cu occurred. The codeposition type of Pb-Sn was normal irrespective the additive in the plating bath; the coloration of the films was bright gray and the morphology was formed of refined crystallites. For Pb-Cu alloy the codeposition type was anomalous to the deposits obtained from baths containing sorbitol or tartrate and normal in the presence EDTA. The Pb-Cu deposits obtained in the presence of sorbitol, EDTA or tartrate showed black coloration; or coloration varying of brown to redish or golden to dark redish, respectively. X ray diffraction spectroscopy of the Pb-Sn and Pb-Cu codeposits indicated that these were to constitute a mixture of compounds.

The effect of galvanostatic electrochemical pre-treatments on the surface composition and wettability of boron-doped diamond (BDD) electrodes was characterized by X-ray photoelectron spectroscopy (XPS) analyses and contact angle measurements, respectively. The smallest wettability was presented by the least doped as-received BDD electrode; however, the wettability of all the BDD electrodes increased after the cathodic and anodic pre-treatments. From the XPS analyses, an increase in the surface O/C ratio after the anodic pre-treatment was observed, which was attributed to the introduction of carbon-oxygen functionalities on the surface of the BDD electrodes. The effects of the current and charge densities applied on the BDD electrodes, during the cathodic and anodic pre-treatments, were evaluated through the redox reactions of the Fe(CN)6 3-/4- couple by cyclic voltammetry and by electrochemical impedance spectroscopy. The high sensitivity of the electrochemical and electrical properties of this redox couple to the surface terminations of the BDD electrodes was confirmed; the redox reaction kinetics are much faster after cathodic pre-treatments. The electrical properties presented by the BDD electrodes after anodic pre-treatmens, characterized by a resistive response in intermediate frequencies, have been explained as due to a possible partial blocking of the surface, which would be associated to the presence of carbon-oxygen functionalities on the electrodes surface. On the other hand, the electrochemical and electrical properties were shown to be controllably modulated through the galvanostatic electrochemical pretreatments. Studies on these properties were also carried out for the Fe3+/2+ and Ru(NH3)6 3+/2+ redox couples. For the former, contrary to that for the xxiv Fe(CN)6 3-/4- couple, the charge transfer kinetics (slow) become faster after anodic pre-treatments, instead of after cathodic pre-treatments. In the case of the Ru(NH3)6 3+/2+ redox couple, the electrochemical behavior is independent of the electrode surface state, the same being true for the electrical properties, whose use to evaluate the quality of BDD electrodes is proposed. Finally, studies on the ferrocenecarboxylic acid redox species in non-aqueous medium (acetonitrile), in the absence and after additions of water (or glycerol), were carried out in order to investigate the nature of the surface partial blocking of anodically pre-treated electrodes, in the presence of redox couples such as Fe(CN)6 3-/4- or ferrocene. The obtained results indicate that such partial blocking is due to the adsorption of water molecules, by hydrogen bonding with the carbon-oxygen functionalities. This partially prevents the access of the redox reaction to electrochemically active sites, thus explaining why much smaller charge transfer reaction rates are attained when anodically pre-treated electrodes are used.

To reduce costs, to minimize risks, to anticipate deadlines and to optimize resources of new product designs it is recommended, whenever possible, to reuse artifacts of existing successful similar products. However, these artifacts must be of easy adaptation to meet the requirements of the new products with a few or no need of re-design or re-coding. This work describes a feature oriented iterative reengineering approach to concomitantly achieve both the revitalization of embedded legacy systems and the incremental creation of a core of reusable artifacts, to support the development of other similar systems, members of a product family. Such systems are generally small and pass through frequent maintenances to support the evolution of the hardware they integrate, accelerating the natural software degradation process. The accomplishment of a reengineering process can extend the life cycle of these systems, improving their structural properties for a better adaptation to changes. Agile principles and techniques are applied throughout the process, providing continuous interactions with the customer and deliveries of executable and tested partially modernized versions in short and frequent intervals, with documentation in appropriate level and prepared for future modifications. Software Product Line techniques are used for the domain modeling and for the design of generic software components. Its activities are accomplished without the need of code freezing or duplication and allow maintenances and interruptions at anytime, without prejudice of the enhancements already developed in all previously ended iterations. A case study is presented to exemplify the proposed approach in a real environment and to evaluate its results.

The Knowledge Discovery in Databases (KDD) techniques have grown from the need for obtain more information about the data stored by organizations, such as, enterprise companies and research institutes. Bayesian Networks (BNs) can be considered as a probabilistic reasoning based model to represent knowledge and are very adequate to KDD tasks. In the last years, Bayesian Networks (BNs) have been applied in many supervised and unsupervised learning successful applications. The process to induce BNs and Bayesian Classifiers (BCs) from data tries do identify a BN (or a BC) able to represent the relationship among the variables of a certain data set. However, this is a NP-complete problem and, thus, its search space may become very large in most applications. That is the reason why many algorithms explore some way to reduce the search space in order to make the learning process computationally viable. In this master s thesis a new Conditional Independence based approach to induce BCs from data is proposed and implemented. Such approach is based on the Markov Blanket concept in order to impose some constraints and optimize the traditional PC learning algorithm. Experiments performed with ten data sets revealed that the proposed approach tends to execute fewer comparisons than the traditional PC. The experiments also show that the implemented algorithm produce competitive classification rates when compared with both, PC and NaiveBayes

The spatial organization of Brazilian cities and the organization of their transportation systems have been causing an uneven accessibility distribution among other issues. This unbalance is marked by the fact that people who use private motorized modes of transportation are the ones that have been benefiting the most while the ones that use non motorized modes have been experiencing the worst conditions. The knowledge about the motorized transportation is much more developed than the knowledge regarding cycling as a mode of transportation. As long as this kind of unbalance remains there will not be equity in the society areas related to transportation. The purpose of this research is to provide general data and the fundamentals to permit the comprehension of the urban cycling transportation characteristics and the ways of organizing the cycling space as well. By evaluating different ways of organizing this space this dissertation presents the ones that had the best results or the ones that have the best potential to favourable results and that are also generic enough to be adequate to a great number of Brazilian localities. Within the chosen objectives the discussions and propositions presented in this dissertation are focused on introducing the bicyclists inside the road system so it would be possible to them to go everywhere in the cities under adequate conditions. Therefore the search was for discussions and propositions that took the bicyclists needs into consideration avoiding the ones that could exclude the bicyclists. This dissertation is focused on ways of organizing the cycling space that are suitable to new urbanization projects but specially on the ones that can fit to the areas with established road systems. This research allowed the verification that urban cycling transportation can really occur in a more harmonious way with the others modes of transportation. The presented and evaluated propositions indicate that cycling transportation is not incompatible with the motorized transportation

The use of analogies is a cognitive strategy frequently adopted by learners when they want to understand some new concept. In that case, the analogy connects the new concept with the previous knowledge, attaching it in the learner cognitive structure. Some studies points out the use of analogies and previous knowledge of learners increases the learning material quality, stimulating the learners to use their cognitive strategies. Nevertheless, there are no studies about a way to enable both the use of analogies and learners previous knowledge to facilitate continued learning, mainly taking into account computational support for e-leaning. In this work it is presented a prototype of an on-line assistant to support a training course about workspace safety issues. The application uses a common sense reasoning engine and the Brazilian Open Mind common sense knowledge base, to make inferences about concepts that might be unfamiliar to the students. It is explored the use of analogies to explain topics, enhancing learning by using context capture to help students associate related topics. It is believed that common sense can be used to take into account cultural considerations while helping learners to build analogies. It is also explored the suggestion of analogies, which were build using commonsense knowledge, to the teachers during the project of instructional material design. Preliminary results with students using the assistant point that they considered analogies useful in the learning process, that the system is helpful in understanding new concepts, and that it helps connect the information searched for with common sense knowledge.

This work aims to understand the organization of the political dimension of the small municipalities before the ideals of democracy and sustainability for public policy and planning. It starts with the hypothesis that the political dimension of the small municipalities is configured by 1) closer relations of sociability (such as mutual understanding, personality, friendship, neighborhood, kinship), 2) institutions of public character (on religious and assistance), 3) and the municipal administration itself (mainly represented by the figure of the mayor). The research strategy is based on the exploratory case study unique. As empirical object was selected Urupês municipality located in the northwestern region of São Paulo, Brazil. Through literature review, exploratory survey, direct observation, interviews, questionnaires and systematization of the data, the results confirm the hypothesis proposed and allow the following considerations: 1) the characteristics of sociability are important and provide channels of communication, participation and social representation to identify the demand and provision of public character, aggravating or benefiting the social and environmental conditions in the city, 2) lack a greater understanding of the role of each actor in society, 3) lack most effective communication not only formal between executive, legislative and judicial branches, 4) entities of public nature, especially of a religious and care nature, play an important role with regard to minimizing social inequalities. Thus, the characterization of the political dimension of the small municipalities proved to be very relevant to clarify possibilities and minimize contradictions for thinking about public policies for sustainable and democratic planning.

The importance of the technology management in Brazilian public universities has been increasing due to the great potential regarding technology transfer from those organizations to industries. After the Innovation Law in 2004, this point of view has been encouraged by the establishment of specific guidelines regarding intellectual property, technology cooperation with outside organizations and the role of universities in scientific and technological development, as a part of the Brazilian innovation system. In this context, the objective of this work was to understand how the public universities of the State of São Paulo structure their regulation of intellectual property and technology transfer processes for companies, as well as to identify forces and obstacles for that practice. The empiric part of the work consisted of five case studies in public universities located in the State of São Paulo, using exploratory and qualitative analysis. The universities studied were: University of São Paulo (USP), São Paulo State University - Unesp, State University of Campinas (Unicamp), Federal University of São Paulo (Unifesp) and Federal University of São Carlos (UFSCar). All the regulations of intellectual property that affect the technological management in those universities were researched, as well as information concerning patenting performance and technology commercialization, including interviews with university technology managers. In order to gain full understanding of how the technology transfer process happens, illustrative studies were carried out, using a contract from each one university (patent licensing or sponsor research contract) involving companies. The results of the work were divided in two categories. A first comparison of more restricted character involved illustrative studies of technology transfer of processes from the five universities. The second, a more in-depth approach, involved considerations concerning technology management in these universities. Regarding the first perspective, the results were shown as a schematic representation for each process, with similar indicatives in juridical-administrative terms. We also analyzed the relationship between the people involved in technology transfer and the characteristics of the organizations involved in it. As a general conclusion, it was noticed that formal technology transfer using intellectual property has been growing in the public universities of the São Paulo State. We could also observe that a process of physical and personnel structuring is taking place in all the cases and that all the universities concerned have intellectual property regulations. The comparative analysis carried out shows which universities are more actively involved in patenting and technology commercialization. The results also demonstrate and discuss the challenges that have been identified for the improvement of technology transfer in these universities. The main ones are: the spread of the intellectual property culture, technology evaluation, establishment and consolidation of best practices in management and international technology protection, as well as alignment of policies among the institutions which share and generate intellectual property.

Lectins are (glico) proteins of non immune origin able to cause cellular agglutination or precipitation of glicoconjugates. Legume lectin refers to plant lectins that are found exclusively in species of the Leguminosae family. A notable characteristic of legume lectins is that all their proteins share tertiary structure consisting of a jelly-roll motif, which is basically composed by β sheet, but present great variability the quaternary association. This variability is considered responsible for conferring different degrees of stability to the legume lectins. This work presents the isolation and characterization of the camptosemin, a protein of legume lectins family, isolated from seeds of Camptosema ellipticum, a plant that belongs to the Brazilian open pasture. Camptosemin found to be a tetrameric protein, whose protomers exhibits approximately 26 kDa. It was able to agglutinate erythrocyte of all ABO sanguineous types and it was showed high affinity for N-acetylgalactosamin carbohydrate. Spectroscopic assays have demonstrated that camptosemin is an extremely resistant protein against the thermal and chemical unfolding. Through the analysis of the unfolding curves and the refolding assays, a model of two states for the unfolding of the protein was proposed. According to this model, at the equilibrium, only presents native tetramers and unfolded monomers. The obtained values of Tm and are in agreement with the ones described for other lectins. G O H Δ 2

The cyborg theme, concerning the combination of organisms and machines, has been extensively explored recently. In this text, the theme is once again discussed, first, through a brief historical overview and, then, through a shift in the paradigm, proposed by the philosopher of mind Andy Clark, known as Extended Mind or Activ Externalism: it s not necessary for a man to have implants or chips in his body, to receive a transplant or to use wearable computers to gain the status of cyborg. The human being is naturally a cyborg, because it has always incorporated tools that extend the mind. Therefore, there is a redefinition of the notion of mind, which frees it from the limits of the skull and extends it to the limits of human action, involving body, brain and world. The brain carries the fate of controlling this material mind, upon which its existence depends

Aquatic therapy is a method of prevention and rehabilitation of handicap. Its specialized learning methods enables motor training and independence in the fluid environment and, therefore, provides a better life quality to individuals. Among the methods used for water interaction with handicapped people, the Halliwick method encompasses a sequence of motor learning pleasurously and actively developed through music and games. With the expansion of aquatic therapy in Brazil, the Halliwick method has been taught in Improvement and Graduate programs in public and private universities. This study investigated the content and teaching method of the Halliwick in Lato sensu courses in the state of Sao Paulo. A qualitative research based on Dialectical Materialism was developed. The praxis category was used to direct the analysis and the confrontation with empiric categories, constructed a posteriori. The sampling involved 3 Lato sensu courses (shortterm graduate programs). Questionnaires were answered by students, and professors from these programs were interviewed, and so were international instructors from Improvement courses. Data were crossed by the Triangulation technique and systematized by Idea Association Maps. Results show that students need to redo the Halliwick method due to unsatisfactory number of hours of the course (16 hours), which presents superficial contents and excessive amount of exercises. Students consider that they need to feel safer with and have more experience in handling handicapped people in future interventions in fluid environment. We conclude that interactional methodologies allow for the compensation of the lack of experience by students and provide a systematization of a teaching procedure of the Halliwick method in graduate programs, defining a form that contributes, as a product, to the inclusion of handicapped people.

Due to its current dynamism and increasing importance in the Brazilian economy, the beef agri-chain in Brazil can be analyzed under different fields of strategy and business administration (corporate strategy, operations management) and marketing (differentiation of products, marketing channels). This research aims to join some of these different research areas, by studding core compences and marketing channels. The research was structured as a multi-case study with 3 of the main Brazilian exporting beef processors. The main objective of the research was the analysis of the core competences of some of the most important Brazilian beef processors, as well as the analysis of the marketing channels of the Brazilian beef in the European market, and to understand how the core competences impact the marketing channels in the European Union. The results of the research show that the Brazilian beef processors distribute their products through different marketing channels in the European Union. One of the companies distributes its products through the use of intermediaries (trading companies and distributors) in the marketing channels. Other beef processor has its own distribution structure in Europe, operating through joint-ventures with local distributors. The last researched company is migrating from the model based on the use of trading companies and distributors to the model of owning its distribution structure in Europe. The research mapped 25 resources, 23 capabilities and 19 core competences which support beef exports to the European Union. Most core competences were based in tangible resources, however the most important core competences which leverage Brazilian beef exports to European Union and impact the structuring of marketing channels in the European market are core competences based on intangible resources, such as: market knowledge, tradition/ reputation, brands and beef quality. These core competencies are sources of competitive advantage, since they allow Brazilian beef processors to gradually establish long term relationships in the marketing channels with their clients. These relationships allow Brazlian beef processors to to migrate from generic marketing channel models, based on the use of trading companies and distributors, to specific marketing channels, such as large supermarket chains in the European market.

The main objective of this research is to describe a methodology for the analysis of environmental impacts due to ecotourism activities, which can be easily employed by tourism managers and planners. The methodology uses multi-criteria evaluation, based in fuzzy logic, together with a Geographic Information System (SPRING) to treat information related to the variables that characterize an area and can influence its adequacy for ecotourism. The selections of the variables to be incorporated in the model for impacts assessment was based on the bibliography and are the ones most used in environmental impact studies including: topographic characteristics (declivity), pedologic characteristics (type of soil) and vegetation and land use characteristics. Other variables may be included in the analysis if the study area has some specific characteristics that deserve emphasis. In the case study, developed in the 29 Dam Region, in the city of São Carlos, SP, the methodology proved rather adequate for attaining the research objectives, allowing the spatial visualization of the results, expressed by classes of adequacy.
