    The aim of this PhD thesis is the ample study of soil and lichen samples from Antarctica, collected in regions under strong anthropogenic impact. Surface soil samples were collected around several scientific stations: Brazilian (Comandante Ferraz), Argentinian (Esperanza), Chilean (Frei Montalva and Escudero), Chinese (Great Wall), Russian (Bellingshausen) and Uruguaian (Artigas). Control soil samples were also collected, for representing areas with low anthropic influence (far away from the local stations). Lichen samples (Usnea antarctica and Usnea aurantiacoatra) were collected near the Chilean and Russian stations, as well as in a control point far 0.5 km from the nearest station. X-ray Fluorescence was used as an analytical tool for the preliminary evaluation on metal contamination in the soil samples. Several extraction solutions (aqua regia, sequential extraction procedure, DTPA and CaCl2 solutions) were used to assess the amounts of metals in the soil samples. For Cd, Cr, Cu, Mn, Ni, Pb and Zn determination in the soil extracts, some analytical strategies were employed, such as fast sequential determination by FAAS in the conventional mode, as well as by using STAT-FAAS and TS-FF-AAS for evaluating Cd and Pb determination in DTPA soil extracts. The chemometric tools: HCA, PCA and PARAFAC were used for soil data treatment. Enrichment factors were calculated in order to infer about the degree of soil contamination. Soil samples collected around the stations diesel tanks were enriched with Cr and Pb. Soil samples from Esperanza station are the most contaminated ones, reaching 46, 18993 and 4823 mg kg-1 for Cd, Pb and Zn, respectively, for the strongest contaminated sites. The use of Flame-AAS and STAT-FAAS in the fast sequential mode appears as a good way that combines higher analytical throughput and better sensitivity (STAT-FAAS). Besides that, minimization of toxic wastes generation and xv economy of reagents are analytical advantages of this approach. The employment of chemometric tools are also an important strategy allowing the visualization of sample groupings and the variables related to them. A fast and simple method for pseudototal determination of metals in soil samples was developed. In this method, the samples were extracted with lower amount of aqua regia and in a reduced time (when compared with the official method) by using inexpensive centrifuge tubes. LAICP- MS was evaluated for direct determination of lead in the lichen samples and to access the distribution profile of this element in the organism structures. Lichen samples from heavily anthropogenic sites (near the stations) have the highest Pb concentrations ([Pb] = 8.71 mg kg-1 for the most contaminated sample and [Pb] = 1.12 mg kg-1 for the control point). LA-ICP-MS emerges as an adequate analytical method for direct Pb determination in lichen samples, notably when using carbon (naturally present in the samples) as internal standard. The medulla region of the lichen thalli is the main Pb bioacumulating lichen region.

    A tese constou de 3 estudos descritos a seguir. O estudo I, intitulado: Programa fisioterapêutico hospitalar de curto periodo composto por exercícios físicos supervisionados melhora a função autonômica cardíaca após cirurgia de revascularização do miocárdio - Estudo randomizado e controlado teve como objetivo investigar se um programa fisioterapeutico hospitalar melhora a funcao autonomica cardiaca (FAC) apos a cirurgia de revascularizacao do miocardio (CRM). 47 pacientes pos- CRM, foram randomizados para: grupo de exercicios (GE,n=24) ou cuidados usuais de fisioterapia (GCU, n=23). A avaliacao da FAC incluiu medidas da variabilidade da frequencia cardiaca (VFC). Na alta hospitalar, GE apresentou maiores valores dos indices rMSSD, AF,SD1, STD RR, SD2, DFA α1, DFA α2, entropia aproximada e media RR, p<0,05. Contrariamente, maiores valores da media FC, BF e BF/AF (balanco simpato-vagal) foram encontrados em GCU. Concluimos que um programa fisioterapeutico de exercicios fisicos, realizado durante a internacao pos-CRM, melhora a FAC. Na sequencia, o estudo II, intitulado: Função ventricular esquerda e adaptações autonômicas cardíacas após RC hospitalar em curto período - Estudo clínico prospectivo. objetivou avaliar as adaptacoes autonomicas cardiacas em pacientes com diferenca na funcao do ventriculo esquerdo (FVE) submetidos a CRM e a reabilitacao cardiaca (RC). Em 44 pacientes divididos em grupo FVE normal (FVEN >55%, n=23) e FVE reduzida (FVER= 35-54%,n=21) a FAC foi avaliada antes e apos a RC. Foi encontrada interacao grupo (FVEN vs FVER) vs tempo (efeito da RC) para dimensao de correlacao (CD) e SD2, com melhora significativamente maior para FVER. Pacientes com FVER apresentaram melhor adaptacao autonomica cardiaca frente a RC. Finalmente, o estudo III, intitulado: Respostas autonômicas cardíacas induzidas pelo exercício durante a RC hospitalar em pacientes submetidos a cirurgia cardíaca e com funções ventriculares diferentes. avaliou se os exercicios fisicos realizados na RC hospitalar podem evocar respostas autonomicas diferenciadas em pacientes pos-CRM e FVE diferentes. Nos mesmos pacientes do estudo II foram avaliados os indices da VFC em repouso e durante os exercicios metabolicos e deambulacao no primeiro dia pos-operatorio (PO1) e na alta hospitalar, respectivamente. No PO1 foram observadas diferencas (media RR e media da FC) entre o repouso e exercicio em ambos os grupos. Durante a deambulacao foram encontrados menores valores da VFC (STDRR, TINN, SD2, entropia Shannon e dimensao de correlacao) para FVER, assim como, para a variacao entre repouso e deambulacao para os indices STDRR, RR tri, TINN, SD2, rMSSD e dimensao de correlacao, P<0,05. Concluimos que em pacientes pos-CRM e com FVE normal, o exercicio fisico hospitalar desencadeou resposta autonomica cardiaca mais atenuada comparado a FVEN.

    The development of the productive chain of agribusiness açaí depends on the proper disposal of by-products generated. The fruit is used currently only the mesocarp for human consumption, creating an environmental problem, since the core represents approximately 75-81% of the total weight of the fruit. The stone of açaí literature reports the presence of inulin, polyphenols and other carbohydrates. Among these inulin stands out for its low calorie and therefore applied in food production light in fat or low fat, as a substitute for fat and sugar. Despite being distributed worldwide, is not produced in Brazil and its imports makes it a product of high cost. Thus the design goal was to develop a method for extraction of inulin on a laboratory scale, aiming its industrial production. In the first stage of the project was undertaken to adapt the methodology for aqueous extraction of açai and the core of analytical methods for quantification of compounds. In the second stage of the project was carried out an experimental design to evaluate the effect of variables in the process of extracting the content of polysaccharides: temperature, particle size of the lump, mass / volume ratio and stirring speed of the mixture. In the third step, through the hydrolysis and HPLC analysis, was not found the polysaccharide inulin. By NMR analysis and infrared is proposed that this polysaccharide is a galactomannan. The content of the core polysaccharide, soluble in water, ranged 2-7%. The insoluble fraction of the core, obtained by extracting basic, representing 15% of the total mass.

    The presence of iron oxide in ceramic tile mass contributes to the reddish color firing of the products leading to a lower aggregate value, not to be regarded as a "noble" ceramic. However, the use of raw materials with low levels of iron oxides (Fe2O3) is economically unfeasible in Brazil, since most of the deposits have iron compounds as mineral component. Thus, the objective of this work was that of studying the interaction of the iron element in the final color mechanism of the ceramic tile mass. For this purpose, we have employed several compositions of stoneware tile mass making use of natural raw materials, and a synthetic flow. This flow is constituted of a vitreous phase of the silicates family obtained by fusion/solidification of oxides and carbonates. Such flow influences the color ceramic mass during the process of sinterization modifying the red color firing into whiteness. That occurs when added in compositions containing clays with high levels of iron oxides. Beyond the physical properties obtained from the different employed compositions, we have also used other characterization techniques in order to study the phenomenon, such as: X-ray photoelectron spectroscopy (XPS), Mössbauer spectroscopy, Xray diffraction (XRD), quantitative analysis of phases by Rietveld method and scanning electron microscopy (SEM). The results have shown that the synthetic flow acts as a modifying agent for color when incorporated with values above 33%wt. in the compositions and temperature at 1,100°C . The color firing modification occurs because the chemical composition of the synthetic flow assists to form new iron compounds, thus making the final color firing light. By using this mechanism in the ceramic substrates, the stoneware tiles can be manufactured using low cost clays with high levels of iron oxides. This method proved to be an economical as well as commercial strategy for the ceramic tile industries.

    The Safety and Health at Work (SHW) management is recognized as one of the main factors so the enterprises may be able to fulfill their basic goals of coast, term and quality. One of the latest management strategies is the Resilience Engineering (RE) approach that considers the presence of four main principles for appliance: Top Management Commitment, Apprenticeship, Flexibility and Consciousness. Considering the intensive use of the concrete precast building systems it becomes substantial to study this section about the SHW aspects on the RE focus and record the good practices held by the companies. This work is based on the proposal elaborated by Costella (2008) which presents an Evaluation Method of the Safety and Health at Work based on the safety management principles and the RE. The case study method was adopted, a concrete precast producer enterprise was searched, which had a qualified management system, and it accepted to collaborate with the research. It was concluded that the researched Enterprise presents evidence of the application of the RE principles, mainly due to the existence of the SHW management. It was verified that there are ordinary and complementary concerns, such as the operation of critical sectors and the maintenance of the equipment currently used in factories and construction sites.

    This research aims to describe, in the organizational dynamics of a clothing manufacturing industry of medium size, more specifically in their sewing unit, the changes occurred during the implementation and use of performance indicators when aggregated in their development concepts and methods of Situated Ergonomics. The Performance Measurement Systems (PMSs) has always been part of the organizations and in recent decades has become more important due to the competitiveness and constant changes of the market as well as evolving toward more balanced structures to include all important factors that influencing the organizations competitiveness. The motivation of this study was the observation that PMSs identifies the priorities of performance in a top-down flow within the organizational structure, usually leaving or passing through the strategy. This process presents a strong bias technocentric, in which it aims to understand the structure and the organization's business processes and relegates to other instances much of real parts which are run by people in the everyday operations. Having the perception of this limitation, among other weaknesses in their development, deployment and use, many of these publishers of these models recommend that development is a participatory process, but does not define the way and depth to examine the reality of working at this level. Situated Ergonomics, in turn, pursued the objectives of well-being of the worker and process performance by analyzing the employee at work during the work activity and its effective contribution through verbalizations and confrontation of representations, so better understand their conditions and determinants. This Situated Ergonomics feature appeared to meet the limitation observed in the development of PMSs in a manner that sought to enter their concepts and methods during the development, deployment and use of performance indicators in the unit of sewing clothing manufacturing industry of medium size. The study was conducted through an action research which aimed to harmonize the cycles of intervention proposed by Haims and Carayon for the implementation of an ergonomics program, based on Situated Ergonomics, and the script development of PMS proposed by Andersen and Fagerhaug. The study indicated that by incorporating concepts and methods of ergonomics located in the development process and review of performance indicators this condition allowed the emergence of knowledge and collective needs, and develop a space for discussion and negotiation that enabled a better understanding of different views on the processes of transformation and its goals on the work carried out and performance indicators. In this context the incorporation proved to be mentioned as an important factor of change in the way the information is used by the SMD stakeholders. Despite the positive aspects of the negotiation space developed in these conditions, it was observed that this area is fragile in the face of contingencies that occur in a medium sized company.

    The Cattle Egret (Bubulcus ibis) is a median sized bird, of African origin, considered as an invasive and exotic species in the American continent. In Brazil, first record was in the north, in 1964. The species have been maintaining a pattern of constant population growth, endangering the reproduction and survivorship of native species, as observed in the archipelago of Fernando de Noronha. The purposes of this work were the isolation of microsatellite loci for the species in question and to genetically characterize Brazilian populations, as a starting point in a study that contributes for the comprehension of the colonization process occurred in the country. Thereafter, two partially enriched genomic libraries were obtained, in which the generated fragments were posteriorly sequenced and analyzed for the presence of microsatellite sequences; being the cloning efficacy of 15.74%. Thirty-two microsatellite loci were selected for the analysis, of which eleven proved to be polymorphic. Content of polymorphic information for these loci varied between 0.079 and 0.453. Fragments of expected size were amplified in the eleven polymorphic loci in other six species from the same family as the Cattle Egret. Six populations from different latitudes in the country were genotyped in seven polymorphic loci. A low variability was found, with mean values of expected heterozigosity in the populations varying between 0.408 and 0.562. The population holding the higher diversity was the northern one, closest to the point of the first historic record of the species in the country. Low genetic structuring by AMOVA was detected, and some values of pairwise Fst and Rst proved to be significant when the pair contained populations from South and North of the country. Effective size (Ne) of the Brazilian population was 6.6 individuals (95% CL: 5.7-7.7). Diversity indices and population parameters analyzed did not show evidence that the dispersion of individuals occurred in a north-south axis, occurring more in an opportunistic and erratic manner. Fernando de Noronha s population, which have been managed by a population control program since 2007, presented diversity levels and population parameters comparable to the mainland populations, what indicates that the species will not be easily eliminated from this area.

    The main purpose of this study is to discuss the controversial grammar teaching role in a student s textbook and in the teacher s guide that follows it, as well as in its methodological orientations. This analysis is carried out taking into consideration the possibility of adapting some of the proposed activities based on grammar as a skill teaching theories. The textbook under analysis is part of a book series which has been developed by the state of Sao Paulo for its sixth year students of public schools. First, we present a discussion about Language Teaching Approach, as well as about Method and Technique according to Anthony (1963), Richards and Rodgers (2002) and Almeida Filho (2003). We also discuss the role of grammar teaching in some of the main foreign language teaching periods, such as Grammar- Translation, Audiolingualism and Communicative Approach. These discussions are aimed at providing a broad understanding of grammar teaching roles so that contemporary grammar teaching theories, such as the grammar as a skill teaching theories by Batstone (1994) and by Larsen-Freeman (2003), could help us illustrated alternative ways of teaching the structures presented in the textbook in question. It seems that these contemporary theories have contributed to the development of activities that may help preteen students take notice of grammar structures through extensive meaningful practice and reflection opportunities. We believe these illustrations may also help students become more autonomous in their learning.

    Compare the values predicted by three equations referenced in the literature with the values obtained by our sample of healthy volunteers in the six minute walk test (6MWT), and establish a new reference equation for 6MWT for the Brazilian population. 89 volunteers were evaluated (43 women) 37.8 ± 15.9 years old by spirometry, assessment of physical activity level by the International Physical Activity Questionnaire (IPAQ) and performed two 6MWT with rest intervals of 30 minutes between tests. For comparison the greatest distance achieved during the 6MWT (WD-6MWT) to the equations provided we used the Friedman test with post hoc Dunn and the correlation of variables with the WD-6MWT Spearman's test and the predictive model was performed multiple linear regression analysis by stepwise method. European equation significantly overestimated (p <0.001) WD-6MWT, Brazilian and American underestimated showed no significant difference. The WD-6MWT correlated significantly with gender (r = 0.46), age (r =- 0.59), height (r = 0.57) and length of the lower limb (LL-C) (r = 0.59). The reference equation was developed WD-6MWT=401.185 - (2.402 x age years) + (43.247 x gender 1 = male, female = 0) + (1.757 x height cm). Therefore, in view of the results obtained, it was possible to predict a new reference equation for Brazilian individuals, which explained 60% of the total variability in 6MWT, and will certainly contribute to improve the interpretation of the exercise capacity of patients with functional disability.

    This dissertation addresses some of the ways which the environmental issue relates to certain standards of economic rationality and the construction of scientific-technical discourse. Its central objective is to discuss a form of sociological interpretation about the social hierarchies produced in the Basin Committees, emphasizing the fundamentals of these discourses and discursive modalities under construction and / or consolidated in this decentralized space of environmental governance. The empirical study is the region of the Basin Committee Tietê- Jacaré, located in the central region of São Paulo. It is the 13th State Committee who, like others, is structured by a tripartite management, State, Municipal and Civil Society. Each segment has 12 representatives who compose the Committee on equal and shall be established in a deliberative power over the management of Basin waters. The works used for analytical investigation are: Boaventura de Souza Santos and Enrique Leff in relation to the discussion of the concepts of economic rationality and scientific episteme and also the work of Pierre Bourdieu and Michel Foucault to conduct a research about social distinction on the water management.

    Infiltration systems aim to reduce the effects of urbanization, waterproofing and runoff, acting at the origin of the runoff. The objective of this project was to monitor a Filter - Swale Trench (FVT) system, built at UFSCar s campus in real scale by retaining the runoff produced by waterproofed areas. The FVT system was built in soil described as sandy loam, with infiltration capacity between 2,30x10-5 and 6,05x10-6 meters/second, and was obtained by doing testes in field using double ring infiltrometer and inverted well, respectively. The FVT system was monitored by measuring the precipitation, the inflow system, the level of water stored, and by verifying that the system functioned during the rainfalls. Sixty rainfalls were monitored, with up to a 48 year return period, with no extravasations. We observed differences between the design and operation of the system, such as the catchment area, the infiltration area and losses in the channel distribution. This shows that the structure is larger than actual scenario. We compared the fine content of the gravel and sand filter and the geotextile s permeability of the infiltration trench, sampled after construction and after about a year of system operation. After the period of operation, the gravel and sand filter showed an average reduction in fine content of 29% and 52%, respectively. The geotextile showed partial clogging, which reduced its permeability by an average of 45%. The system has been modeled using the PULS method and SWMM model. The PULS modeling method allowed us to determine the water storage level satisfactorily. Graphically, the storage level curves are similar, with average values of the Nahs - Sutcliffe coefficient (NS) of 0,43, a mean maximum storage level error of 29% and mean empting time absolute error of 36%, obtained in the validation model. The SWMM model enabled the microbasin simulation to run a Departmento de Medicina bulding and the FVT system performed unsatisfactorily and demonstrated some limitations. The model validation presented absolute mean errors of peak runoff at 58%, accumulated inflow volume of 35%, mean error of the maximum storage level of 72%, mean error of emptying time of 79%, mean NS values of inflow of 0,02 and mean NS values of storage level of - 0,79. Using the SWMM model resulted in lower levels of storage and smaller emptying times than those using the PULS model. The system maintenance summed up in cleaning the land, removing sediments from the measurement channel, and performing gardening services. The system maintenance cost in the first year of operation was R$ 85,00 / month or R$ 0,67 for each square foot of impervious drained area, considered high compared to maintenance costs of conventional drainage systems.

    The purpose of the study was to evaluate the economic viability of Crop-Livestock Integration System (SILP) in a experimental unit of EMBRAPA, stade of Mato Grosso, Brazil. The research was held on 100 hectare farm area under commercial conditions of production. This production system can be considered as an alternative for tradictional land use. It is able to increase agricultural production and avoide exploitation of new agricultural areas in environmental sensitive areas. A case study exploratory research was conducted. The approach to the problem was quantitative and qualitative, by the use of statistical tools for data collection and processing, and the analysis of variables. It was collected economic and financial data in real conditions using spreadsheet software. This information was presented by means of cash flow, which allowed to produce economic indicators and analysis, since the implementation of the project until the marketing of the products for a period of 5 (five) years farming, providing relevant analysis and interpretation of indicators based on analysis of cash flow, such as NPV. An economic analisys of the SILP is provided, showing its advantages and disadvantages for farmers and giving more information for analysis and decision making related to its adoption. It was shown that SILP is economically advantageous when compared with the monoculture of soybean. Even though SILP is a technology still under development, it proved to be advantageous because positive economic returns, and especially because it provides diversification of productive activities, generating greater stability at less risk.

    Several studies cite the pollution of stormwater as equivalent and sometimes even superior to those found in the sewers. According to this premise and thinking about environmental issues, especially in the contamination of groundwater and the spread of waterborne diseases, the quality of rainwater has become an important focus of study. This work concerns the monitoring of an infiltration system consisting of grass filter, trench and infiltration trench, built in full scale on the campus of University Federal of São Carlos - UFSCar, located in São Carlos - SP, from the assessment water quality of runoff directly before and after passing through the proposed infiltration system, parallel to monitoring the quality of rain water, through analysis of the physico-chemical and bacteriological established in legislation and international experiences, compared the conditions of the study area, and exploratory data analysis by two chemometric techniques: Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA). According to the analysis of the results variation, especially the quality of atmospheric water and quality of direct runoff results were obtained as concentrations low significantly to parameters Turbidity, Color, ST, STD, Nitrate, Nitrite, Ammonia nitrogen, Sulfate, Chloride, Cadmium, Copper, Lead and Zinc in the water samples analyzed directly from rain, compared with previous studies in the literature and standards and legislation existing about water resources, and the efficiency of the infiltration trench in the removal of Zinc (90,89%), Cooper (88,31%), Electrical Conductivity (31,40%), Ammonial nitrogen (24,32%) and Chloride (5,88%) compared with the predial direct runnof in the channel. With regard to PCA analysis, proves the characteristics between samples according to the conditions of sampling (day, month, place and time) and analysed variables, dividing into groups of samples and contributing to the extraction and interpretation of information unlikely to be viewed directly in the data matrix. The analysis complemented by HCA analysis by PCA.

    Football has been known as an arena marked by masculinity, but in a very particular manner, mainly heterosexual. That could be explained through the way the game has been constructed, in a defined performance focused on what would be inheriting to a condition of what is ideally understood to be a man. In that context, the conformation of the bodies to the practice of football in many countries, especially Brazil, induced the idea that it a sport that is neither suitable nor desirable to the female body. Therefore, the women have been reduced to spectators and their entry in that universe restricted to what could be considers appropriate to a woman. However, we have witnessed a continuous subversion of that space and its representations, which goes from the amount of women in stadiums to the number of women who have professionally inserted themselves in many areas in the sport, insofar as if football can be understood as an institution that for some thinkers expresses the Brazilian society on the symbolic plan, understanding the role played by women in that universe and in what way that space is occupied can be very relevant. In that sense, the study of such roles, as players, referees, journalists and supporters may reveal different nuances of a new spectrum of representations formulated by old and new actors that operate in that space.

    One of the benefits of Service-Oriented Architecture is to make business processes adaptable when this architecture is adopted during software development. For reaching this purpose, it is essential to have a support for services identification in order to meet the business goals. However, many available services found on web environment are too specific and can hardly be reused in different applications. This happens because there is a lack of systematic approaches for supporting generic services identification in a systematic way. Objective: Presenting a strategy for identifying generic services that support business processes. The identification is supported by Goal Diagrams and Business Process Models and is composed by a set of guidelines which assist the domain engineer in extracting the services. The identified services are generic enough to be reused in similar applications of a specific domain. Methodology: To elaborate our strategy, some domain-specific business process were analyzed, aiming at extracting key tasks and turn them into generic web services. This analysis was supported by an extended version of goal diagrams (GTR) and conventional BPM models. Results: As a proof-of-concept we applied our strategy for identifying services in the planning processes domain and we developed a real e-gov web portal based on the identified services. The web portal was used successfully by two different schools for elaborating their planning processes. Conclusion: We claim that our strategy is generic and can be applied to other business processes providing software suitability to the organization dynamics, besides the potential reuse of services in different instances of the same business process.

    This dissertation proposes an essay based on three ethnographic experiences with folhetos de cordel booklets of narrative poetry from Brazilian Northeast. The starting point is my participation in the development of new instruments of classification for folhetos s collections at the archives of the Brazilian Studies Institute of the University of São Paulo (IEB--‐USP). In first chapter I describe the archive life through an ethnographic account of the day--‐to--‐day activities in this environment that remains unfamiliar for the majority of anthropologists, and which led me to meet the poets themselves in the Northeastern state of Pernambuco. The second chapter refers to a brief ethnography with some eminent poets, among them J. Borges. His poetic concept of lie appears in third chapter as an ethnograp

    In this work, We report studies on samples of graphite few layers obtained from micromechanical techniques of cleaving Manual of highly oriented pyrolytic graphite (HOPG). In order to checking the number of layers in each sample, each was physically characterized by spectroscopic measurements using the Raman technique. We studied the ratio of the intensities of the first-order band permitted G, and the second-order band resonance G′(2D) (IG=I2D), from Raman spectroscopy, provides useful information about stacking of graphite layers to verify the presence of few layers in the samples. The results of this study show that by Raman spectroscopy is possible to obtain information from the structural composition of the material and allows knowing the stacking of graphite layers in the samples. Since was used HOPG, there is no information of the size of crystallite represented by disorder induced D band , since this material has long range crystalline symmetry where the crystal size is much larger than the spot of laser used for the measurements.
