The Brazilian industry has been going through constant and significant changes in its work and production organization forms and these changes are being strategically used with the intention to keep assured the conditions of competitiveness and survival of these companies which are facing a globalized market of intransigent competition. These changes are provoked, then, by political, economical and social influence of national and international scenarios. Considering this subject of extreme relevance to the industrial world, we initially aim to show a literature review on evolution of production systems, especially in the automotive industry. We carried out then a Case Study to show the characteristics of the production system used in one of the Volkswagen of Brazil plants and to analyse the work organization implemented in the machining block sector. Further, we present a proposal of the work organization, in which the activities, executed for specific functions so far, would be consolidated in only one function, that is, what was done before by workers with specifics knowledge for each task (of production and maintenance) would begin to be executed by the same workers, but now with the knowledge about the whole productive process and not just with a more localized one (mechatronics). This form to organize the work with polyvalent professionals could provide, in theory, better results in productivity, without imputing to the workers harmful work conditions. We are treating this proposal as a future possibility, since we cannot assure right now that the company will put the necessary changes it into practice.

In this work the problem of the multimedia content distribution to a large number of computers is addressed. Specifically, we consider the problem of the server overloading that occurs due to the increase of the volume of requests to receive content. The consequence is the increase of response time and denial of service. As solution a communication model complementing the traditional client-serve is presented. It is based on the cooperative networks, where the clients cooperate to distribute the media, where they act as a kind of temporary server, until the server come back to a normal stage. Using such redirectioning scheme, the data networked traffic on server is decreased which alleviates its load. The proposed solution is shown in detail, pointing the modifications in the traditional model.

With the reduction of vineyards in São Roque, the wine industry of this region has been seeking for alternatives to produce common wine with low cost. In the present work, wine production from Italia grape obtained at the Góes Wine-cellar (São Roque SP) with the wild yeast and the selected yeast (Y-904 Mauriferm from COATEC) was studed. Following a 22 factorial design complemented with a star configuration 44 experiments were carried out in bench scale bioreactors with 1 L working volume, whose fermentation conditions were initial pH values of 2.8, 3.0, 3.3, 3.6 and 3.8 and temperatures of 18, 20, 24, 28 and 30oC, being 22 with and 22 without skin. These experiments permitted to study the influence of initial pH and temperature in the ethanol and glycerol formation during turbulent fermentations in the presence and absence of skin. Besides, the advantages and disadvantages of the selected yeast in comparison to the wild yeasts were also evaluated. The results showed that high ethanol production from the Italia grape variety could be achieved, reaching up to 10 °GL. It was also observed a strong influence of the skin presence during the fermentation, but the wine made in the absence of skin produced colorless white wines with more pleasant flavours than the wines made in presence of skin. Furthermore, was observed that the wild yeast showed higher yield in converting sugar to alcohol than the selected yeast, however the later made higher glycerol concentration than the former. It was also noticed that the optimization results were consistent to the experimental ones. The feasibility of implementing the fermentation in the absence of skin as well as of employing the selected yeast in real production conditions was investigated by perfoming experiments in 1000L vats of Goes Wine-cellar. The results attained were compatible with the ones from the bench scale experiments. However, smaller values for the final ethanol concentration were observed as a consequence of the lack of temperature control, which caused more losses of ethanol due to evaporation. The major contribution of the present work, tested in the lab experiments and confirmed in the fermentations carried out at the Wine-cellar, is the development of a simple method for skin removal prior fermentation, which resulted in an important improvement in the quality of white wine made from Italia grape.

The present study deals with the analysis and interpretation of changes that have occurred in the context of medium sized urbanizations in the state of São Paulo, specifically those that have been part physically and economically of the Administrative Region of Campinas, one of the areas that has shown dynamic processes of territorial and populational expansion, during the period of political, economical and social transformations in Brazil, taking as a time reference the period from 1960 to 2000. As a local reference, we have the Metropolitan Region of Campinas, considered to be the third largest industrial center in the country, right after the metropolitan areas of São Paulo and Rio de Janeiro. The city of Limeira was chosen as the central object of this study, a medium sized urbanization inserted in the regional context and influenced by the processes thereby derived which has shown a record of transformations connected to the expansion of urban networks and population growth in the last 40 years. The social-spatial dynamism of the city was analyzed here, observing the relations of the federal, state and regional economy with the conformation and configuration of the occupation of the spaces that are part of its urban tissue. In the same way, relations were observed between the increase of the city urban population and the issue of appropriation of urbanized land as an inducing element of spatial growth. Historical, economical and social happenings were also focused on in these interpretations, seeking to assess the expansion dynamism of the city along with the dividing up of the land, in this case as a forming element of the process and connected to regional formation. In relation to actions and agents that implemented the occupation of the city land, the performance of public authority and private initiative was observed in these scenarios, demonstrating some of the features of the way space is utilized in Limeira.

Family Characidae consists of approximately 30 highly diversified subfamilies that probably do not comprise a monophyletic group. However, a few particular subfamilies may constitute monophyletic groups sharing specializations. In the present work, nine specimens belonging to six genera were analyzed using classic staining techniques as well as fluorescent in situ hybridization (FISH) and GCspecific fluorochromes, such as Chromomycin A3 (CMA3). A diploid number of 2n=58 chromosomes was observed in Myleus micans, with 26M+18SM+8ST+6A; 2n=50 in Astyanax lacustris with 8M+20SM+16ST+6A; 2n=50 in A. altiparanae with 8M+20SM+12ST+10A; 2n=50 in Astyanax scabripinnis with 12M+24SM+2ST+6A; 2n=50 in Orthospinus franciscensis with 12M+30SM+2ST+6A; 2n=52 in Piabina argentea with 8M+14SM+16ST+14A; 2n=52 and three cytotypes in Serrapinnus heterodon, with 17M+20SM+14ST+1A, 16M+20SM+14ST+2A and 15M+20SM+14ST+3A; 2n= 52 in Serrapinnus piaba with 16M+20SM+14ST+2A; and 2N=50 in Hasemania nana with 8M+42SM. FISH results with the 18S rDNA probe indicated the presence of these genes in the chromosomes where NORs were active, besides additional sites, as seen in M. micans, A. scabripinnis, P. argentea and S.piaba. Similar to the NOR sites, the 5S rDNA regions were evidenced in different numbers and positions throughout the studied species. The data obtained corroborate the chromosome diversity often reported for Characidae, reinforcing its polyphyletic condition.

The present work has as objective the comparative study between anticorrosive painting systems with two types of vehicle - aliphatic polyurethane and acrylic polyurethane - loaded with different concentrations of iron oxide of the red type (OFV) and the micaceous type (OFM), new and after aging under UV radiation. A set of fourteen different painting systems was studied, that vary between itself for the type used vehicle, as well as for the type and concentration of iron oxide added. Samples in form of free films had been submitted the assays of transport and sorption of water, ionic transport, Scanning Electronic Microscopy (MEV) and Atomic Force Microscopy (AFM). As general conclusion, the results show that for all the analyzed systems, the dispersion of pigments is below of the desired one, with formation of porous aggregate of the solids particles. This fact is evinced from the results of transport and water sorption, where an increase of the solubility of the systems with the increase of the pigment concentration was observed, and also, from images of the morphology of the samples, obtained from MEV analysis. The aged systems had presented permeabilities higher than those for the new films, in all the range of concentrations, being that in the case of the loaded systems with micaceous iron oxide the effect of the aging was small, in comparison to of the red iron oxide. The effect of the aging also can be observed through the images obtained from MEV analysis, for all the systems, as well as from images of MFA obtained for two specific systems. Assays of ionic transport had been carried through for four selected systems, and had corroborated with the results of transport and sorption of water. In this direction, four systems between those studied had been selected, that the carried through assays had presented better performances in all: aliphatic polyurethane with 5% of OFM and 35% of OFV, and acrylic polyurethane, with 5% and 35% of OFM.

New software development approaches have been proposed in order to permit the increasing of productivity and application quality. Among these approaches, the software development based on components can be evidenced. This approach is characterized by the software component reuse. In order to permit this reuse, it is necessary a repository which is responsible for storing, searching and retrieving software components. In this context, this work aims to identify and model component metadata on databases, allowing the definition of eficient search strategies to retrieve such components. For reaching these goals, information retrieval concepts and the ART-2A self-organizing artificial neural network architecture were adopted. Experiments were conduced to conrm the viability of this proposal.

The Quality of Service (QoS) available in the network is the most important parameter for the guarantee of the success in a multimedia transmission [Dressler 2003a]. In the current context of multimedia systems, handle systems to QoS control are essential to the applications have the desired quality in the service accomplishment. The human user of a multimedia application is the initial point of all the considerations regarding QoS, having this that worry about the perceivable effect to this user. Usually, users are not aware on how to specify low-level parameters, such bandwidth, not even to understand numerical values related to measurements of these. Thus, it is necessary that the system provides an abstraction level, so that the user can understand which is the quality of service which the network can offer in a certain instant. Then, the user can decide if he will place the application in execution or not. This work presents a new method to express the Quality of Service (QoS) in a multimedia connection. This method uses discrete values of QoS parameters, establishing a relationship among them through the use of a Fuzzy Genetic Rule-Based System (FGRBS) to obtain a single value that expresses the QoS of the connection. This final value is classified within a predefined QoS specification standard consisting of three sets: Optimal, Acceptable and Unacceptable, resulting in a definition of the Quality of Service in a user-level language.

In order to attend the market quickly, a company need to have flexibility and to change its production line, to assist to the production of personalized products, to change the raw material or, even, the conception of the product like in an automatic system of manufacture. Administration of processes, industrial automation and IT (Information Technology) are essential to guarantee not only the companies, competitiveness but their survival inside of this scenery. The larger interest among the automatic systems of manufacture in this work is the flexible manufacture system (FMS), for its inclusion and complexity and, consequently, its control and the variety of architectures, as the centralized, the hierarchical, the heterarchical, the hybrid and, finally the multi - agent, therefore the main focus of this work will be the control system of a FMS. So one of the architecture alternatives, is the proposal using a system of hybrid control, because it allows the communication among levels, by sidelong, and the modules involved in the production process and factory ground control, so it will be possible, to determine which are the instances or moments so of decision, describing the used functions, as well as the treated information. To make possible the modeling modules are used: manager, selective and movement controller facilitating the construction of a structured algorithm aiming at the detail of the process mapping of communication about the actions unchained in the factory ground.

The objective of this dissertation is to verify if there is a relationship between the characteristics of the urban form and option for walking trips. For this relationship to be studied, the first step was a bibliographic review about the urban form characteristics that might influence the option for walking. Among the methodologies that could be used to evaluate the modal option, a logit-type Discrete Choice Model, was chosen. The data used for the calibration of the model were collected in São Carlos, SP, a Brazilian medium-sized city with around 200 thousand inhabitants. The analyses were developed at census tract level, with a Geographic Information System (TransCAD). Two logit-type models were calibrated. The first one (basic) includes only a socio-economic variable (automobile availability) and the trip length. The second model (expanded) includes, besides the variables of the basic model, information about the characteristic of the urban form in the trip origin sectors. The comparison of the results obtained with the two models, allowed the evaluation of the marginal influence of urban form variables on the mode choice. In general, the expanded model was statistically better then the basic one. The results suggest that urban form characteristics do influence the individuals´ option for walking.

Clavulanic acid (CA), a secondary metabolite from Streptomyces clavuligerus, is a potent inhibitor of β-lactamases, being formulated by harmaceutical industries with other β- lactams antibiotics to produce drugs that overcome the resistance to antibiotics of many pathogenic bacteria. Studies on culture medium composition, as well as how each component is added to the broth are essential for improving and developing fermentation processes both in obtaining high productivity, as well as in simplifying the separation and purification of the final product. The lipids become an interesting alternative to be used in CA production process, once they constitute a concentrated source of energy slowly assimilated by microorganisms. With relation to the nitrogen source, soybean derivatives, as flours and protein isolates, have been used successfully in the production of CA, by supplying precursors for its biosynthesis; however, the appropriate amount of this nutrient in culture media has not been properly established so far. The general objective of the present work was to study the culture medium composition on the improvement of CA production by S. clavuligerus in bench scale bioreactor, using complex nitrogen sources, and lipids as supplementary carbon source. In preliminary cultivations in shake flasks, the effects of nitrogen source and concentration, using soybean flour and Samprosoy 90NB (soybean protein isolate), were studied. The total nitrogen concentrations of 1.6 and 3.2 g.L-1, and soybean oil concentration of 16, 23 and 30 g.L-1 were tested. The results obtained showed that, when the concentrations of soybean oil and initial soybean flour were 23 g.L-1 and 20 g.L-1, respectively, the CA production obtained was 700 mg.L-1 in 132 hours cultivation, and at pH values above 7.0 the production process was severely harmed. In conventional bioreactor cultivations, under pH control with acid or base addition, all the cultivations were marked by the high CA production and productivity, accompanied by small degradation of the product. The culture medium composition and cultivation conditions that generated best results, concerning CA production, were as follows: 800 rpm, 0.5 vvm and pH 6.8, soybean flour and soybean oil concentrations of 40 g.L-1 and 16 g.L-1, respectively. Under these conditions, a maximum production of 906 mg.L-1 of CA in 84 hours cultivation was obtained.

The Domestic Solid Residues (DSR) have been discussed thoroughly on the part of The Public Power and the civil society, before the demands of the implantation of sanitary embankments, the construction of separating composting, selective collects, action of street and sanitary embankments workers, the formation of work cooperatives, collection forms and payment of the services, among others. This last subject, which sends to taxation forms and financing the activities of the system of solid residues, has not still been approached sufficiently in research terms, above all in municipal districts of small and medium load. Because of it, this work search intends to analyze the services related to RSD rendered by the municipal administration, through the identification of the equipments and people involved, as well as the operational and administrative costs, in the routes and collection ways (selective and pattern), of the amount of residues and disposition places. For that it was made the characterization of the activities related to DSR based in the structure, collection system and disposition, through data collected in the municipal administration. It was observed that the total cost of the collection of residues is distributed in 69,6% personal total and 30,4% representing the equipment total, maintenance, fuel and capital costs, totaling the worn-out value for the Municipal City Hall of Jaboticabal in the collection services and disposition of the urban solid residues. Analyzing the amount of urban homes in the municipal district and the values attributed in the costs of the collection services and disposition of the residues urban home solid is verified an annual medium cost by home in the order of R$ 72,00 (seventy two real). Taking as study object the municipal district of Jaboticabal - SP was made a characterization in neighborhoods, diagnosing the volume, type and pattern of residues of the selected properties. The characterization and differentiation of the general profile of the three selected neighborhoods were made, through the descriptive analysis and for the processing of statistical analysis techniques, using of variables: socioeconomic, generation of home solid residues and the consumption of water. Comparing the medium consumption of water in the researched residences, with the socioeconomic profile and the generation of home solid residues, was noticed that the pattern of consumption of residues, the income " per captures " of each neighborhood and the medium consumption of water: 40,05 m³/water (Nova Jaboticabal neighborhood), 27,17 m³/water (Aparecida neighborhood) and 16,54 m³/water (Conjunto Habitacional Ulisses Guimarães) are directly correlated. After characterizing the service of collection of the home residues and trace the general profile of the neighborhoods they were correlated and analyzed, together the 9 selected variables, through statistical analysis (main components, grouping, factorial and discriminant) looking for the elaboration of an exploratory model of taxation that is taken in consideration the socioeconomic profile, consumption of water and generation of the residues of the homes involved. The technique of grouping analysis divided the homes in three groups in agreement with the similarity of acting of the used variables, so that those homes that presented close actings were in the same group. Two variables identified as significant, being the Family Income and IPTU. So it can be said that with the values of IPTU and Family Income applied to the model it is gotten to identify what group belongs the analyzed home contributing like this in the taxation process, because the same ones can aid in the base of calculation of the municipal district through an exploratory model.

Raputia praetermissa (Engler) Emmerich is a tree found only in the Forest Reserve Adolpho Ducke, Amazonas, Brazil. The genus Raputia was originally described by Engler and many species were included in this genus, but in 1978, Emmerich proposed three new genera Neoraputia, Raputiarana e Sigmathantus in order to accommodate six species, four belonging to the genus Raputia, which is assigned into the tribe Cuspariae, and two that had not been described yet. From our knowledge no previous phytochemical work has been reported on Raputia. Therefore, this study describes phytochemical and chemosystematic investigation and the search of compounds with trypanocidal and leishmanicidal activity from roots of R. praetermissa. The phytochemical work involved crude extract preparation, followed by fractionation and isolation of compounds thorough different chromatography methods. Spectroscopic analyses permitted the identification of them and the results showed the presence of new substances in addition to those isolated previously. Here we reported the isolation and identification of the new compounds: two new limonoids, 11β,19α-dihydroxi-7- deoxo-7-acetoxy-ichangin e 11β,19α-oxide-7-deacetoxy-7-hidroxy-ichangin, two new prenylated indoles alkaloids, 5-[(3 -dimethylalil-4 -methylidene)-2 -tetrahidrofuran-2 - il]-indol e 5-[(4 -carbomethoxy)-furan-2 -il]-indol and a new bisindol alkaloid, 5 ,6 -[5- methyl-5(7-indol-5 -il-etene-6,7-diil)-3(1-methylprop-2-en-2-il)]-ciclopentane-5 ,6 -diilindol. The following known substances were also obtained: T-cadinol, β-sitosterol, stigmasterol, campesterol, 3-[2 ,6 -dimethoxy-6 ,6 -dimethylpyrano(2 ,3 :3 ,4 ) phenyl]-methylpropionate, 3-oxo-cadinol, lanosta-7,24-dien-21-oic acid-3-oxo, dictamine, γ-fagarine, 1-methyl-4-methoxy-2-quinolone, tricoccin S13 acetate, 6- formylindol. Our results showed that the chemical classes isolated from R. praetermissa roots are common to the Rutaceae family, but the prenylated indol alkaloids are not. These compounds are new classes of prenylated indol alkaloids. However, all isolated compounds confirm the assigned it into the tribe Cuspariae. In addition, the compounds were evaluated for: a) in vitro biological activity against trypanosomastigotes forms of Trypanosoma cruzi and amastigotes forms of Leishmania braziliensis; b) enzymatic inhibitory activity on glyceraldehydes- XXXII phospato-dehidrogenase (gGAPDH) of T. cruzi and enzymatic inhibitory activity on adenine-phosphoribosyl-transferase (APRT) of Leishmania tarentolae. None of isolated substances were promising against T. cruzi in vitro test as well as in enzymatic experimental models (gGAPDH e APRT) from which they not showed enzymatic inhibitory activity. Conversely, the T-cadinol was active against L. braziliensis and results in DL50 44 µM.

Researchers, public employees and technical person in charge of the Urban Planning, more and more, need instruments that serve as support in the process for taking decisions in the formulation of strategies and politics destined to the preservation or improvement of the social well-being. In that sense, considering the potentiality that presents the study of the Quality of Life for the development of those instruments, the present work has as objective to analyze and to criticize some experiences that tried to operate the study of the Quality of Life when it is applied in the activity of the Urban Planning. In such objective, a revision of the technicianscientific literature about Quality of Life was accomplished with the purpose of being formed a theoretical referential on the theme, referential necessary for taking place the persecuted analysiscritic. Still, it was accomplished the identification and presentation of four instruments that intended to analyze and to evaluate the Quality of Life in the environment urban, contemporaries instruments, located in different contexts: Brazil, Canada, Portugal and Chile. The study was concluded with a critic of the same ones, having used the following analysis categories: managements, objective, conception, dimensions, form of elaboration of the instrument, structure and spatial reach. As resulted of the work was found that, in the analyzed experiences, the study of the Quality of Life in the urban environment has been a concern of the partner between the public management and academic research with the objective of evaluating the social well-being to give support the process for taking decisions in the formulation of the strategies and politics necessaries for the preservation or improvement of that well-being. The Quality of Life in the urban environment, in such those experiences, it has been considered as synonym of the conditions of life of the population or as the combination of the conditions of life and satisfaction of the population with those conditions,. Conceptions that have been approached through a dimension objective-material-quantitative (conditions of life of the population) and other subjective-immaterial-qualitative one (satisfaction of the population), dimensions that have been resulted of a vision technical or academic. The instruments have been operated through different domains, variables and indicators. The indicators, mainly, they have been developed with an objective-quantitative character, the ones that have been leaned in some cases with a satisfaction research - subjective-qualitative character -. The instruments have been developed with capacity of application in form spatially disaggregated in function of the homogeneity of the groups of people. Such resulted have been opposed with the theoretical referential showed from the revision of the technician-scientific literature about Quality of Life showing some observations in the conception, complementarity of the dimensions and participation of the population in the construction of the instruments. The Quality of Life, in the literature, it is pointed as the level of satisfaction of the population in function of their condition of life, the one that is evaluated from the particular values of the same population in a physical context". Situation that distinguish the satisfaction and condition of life of the population as the two dimensions under the which it has to be examined (dimensions objective and subjective), dimensions that have to refer the same subjects and; the particular values of the population as the aspect under which the priorities of the same population might be reflected with the participation the same one in the construction of the instruments. Key words: Urban planning, Quality of urban life - index, Indicators of quality, Methods of evaluation.

The purpose of this work is to present a generalized version of the classic Ljusternik-Schnirelmann theorem given by H. Steinlein [16] by using the con- cept of genus (c.f. [20]) of a Hausdor® space M with a mapping f : M ¡! M which generates a free Zp-action over M and to estimate the value of the genus of Lk;p, a special space used to construct an upper bound for the genus of (M; f).

Currently, some genomas of creatures are being mapping, so enormous amounts of data are being generated. This data is sometimes stored in different data sources and at many times, these sources are heterogeneous and distributed, which results in the necessity of the use of new query techniques and integration of data. After this, the biologists can usufruct greaters and better resources during the research process. This work has the proposal of to build a Bioinformatics environment for the integration of different data sources and their reorganization in a centered source that supports a flexible and efficient manner to build queries. The environment is called as Bio-TIM, which is composed by three layers. The main one is called "Mediator" and it is composed by a connection manager for databases management systems, by wrappers, by a Data Warehouse and by a specific database.
