This research is inserted in the realm of Applied Linguistics studies and aims to identify mediating actions performed by students in the 2007 class of the Specialization Course Teaching and Learning of the Portuguese Language for through the interpretation of messages posted in the discussion forum. During the activities developed in the course of Linguistic Pragmatics discipline, the finding that some students when interacting with their classmates acted as mediators led to the conception of this research whitch investigated the conditions that can make the student a mediator, thus contributing to the study of semiotic-pedagogic mediation that takes place in the online context. By starting from the Vygotsky’s notion of mediation (1967/2008), the theoretical foundation of this study was grounded in authors interested in researching on the conditions under which interaction through forums are carried out in the online courses – such as Gunawardena (1999), Garrison e Anderson (2003), Pallof e Pratt (2004), Coffin et al. (2005, 2006), Celani e Collins (2006), Collins (2008), Coll e Monereo (2010), Monereo e Pozo (2010), among others. The interpretation of messages posted by student mediators was based on the hermeneutic orientation supported by Ricoeur (2002, 2006, 2009), for whom the actions expressed in written texts can become an object of science. The research interpretation indicates the importance of the discussion forum as a privileged space for mediations made by students toward their peers.

O ambiente deposicional da Formação Carajás e uma proposta de modelo evolutivo para a Bacia Grão Pará
(Universidade Estadual de Campinas, 2003-08-20) MACAMBIRA, Joel Buenano; SCHRANK, Alfonso; http://lattes.cnpq.br/5381945062567191
The large Carajás iron ores belongs to the Carajás fonnation, which is a 1 00-400m thick banded and laminated iron formation Gaspilite ), located at Pará state in North Brazil. This almost continuous formation outcrops for at least 260km, in 60 ore deposits, distributed in three main ridges, São Felix, Leste and Carajás. The last one is a sinformal structure sub-divided in South and North ridges. This work was carried out on detailed mapping, stratigraphic raising and petrographic, geochemical, isotopic and geochronological sampling of the North ridge, where the mining activity is currently running and bench and drill-core are available. Leveis ( 4 J.Ul1 to 3 cm) composed by chert or jasper alternated with magnetite-maghemite-hematite was deposed between 2,754 and 2,744 Ma (22m/Ma) at depths of 100-200m, locally affected by bottom currents. This hydroplastic chemical sediments precipitated by supersaturation (Si) and oxidation (Fe) from upwelling waters where the base was richer in hydrothermal source waters (LREE=6,66; Eu*=3,54; (La/Yb),=l,52) than the top (I:REE= 3,89; Eu*=3,18; (La/Yb),==,66). Besides, the major elements content have more variability at base than top. The Carajás jaspilite have twice Ga (2lppm), Bi (6ppm), Pb (18ppm) and seven times Sb (7ppm) than the world average for similar rocks. The Fe oxidation may have be promoted by organic activity, attested by delicate double wall spherulites and kerogen preservation in siltstones of a light younger unit. Local hydrothermal carbonatization has affected the jaspilite producing 813C mean of -4.3%opoa and two groups of 8180 (+24,9 to +15,4 and +12,8 to +6,6%osMow ). Otherwise, metamorphic imprints on this rocks are minimal. Regional work, bibliographic compilation and correlations of the Carajás formation with overlying units ofBahia and Azul mines leaves to propose a evolutionary model for the Grão Pará Basin, initiated as a intracontinental rifting stage, marked by crusta! contaminated tholeiitic basalt volcanism (2.76 Ga- U-Pb zircon ages). The second stage was the deposition ofthe Carajás formation over a wide, quiet marine continental she1f, in:fluenced by upwelling of Fe-Si rich waters. In a third stage, the last was recovered by volcanics associated with clastic sedimentation (2.74 Ga- Pb-Pb zircon ages). The fourth stage comprises the installation of another continental shelf environment, where clastics and carbonate rocks has deposed (2.68 Ga - U-Pb zircon ages). Basin inversion and fluvial deposition closes the evolution.

Análise comparativa da alteração dimensional de materiais de moldagem elastoméricos, através da técnica do casquete
(Universidade Estadual de Campinas, 2000-09-18) ANDRADE, Cícero Almeida de; SILVA, Frederico Andrade e; http://lattes.cnpq.br/2282864112869742
The present study assessed comparatively the dimensional change of four fluid-consistence elastomeric impression materiais (one addition silicone, two condensation silicones and one mercaptan) using the headcap technique. A metal cast (pattern) was made, enclosing two teeth with metal-crown preparation. On this cast, with a 0,3-mm metal relief, were obtained the headcaps using Neelon's technique (brush method). The impressions were carried out with a static-weight press, where a strength of 39.2 N (newton) was pressing the trays over the metal cast. The occlusal surfaces of the prepared teeth had cross-wise grooves. In the extreme of each groove there were small points where the reading started. The linear reading, in a comparing microscope, was initially done at the occlusal surface of each teeth distinctly, so following it was read matching the points between the two teeth. The results were statistically analysed and it followed that there were no statistically significant differences.

Análise da interferência de dois procedimentos na aprendizagem operatória
(Universidade Estadual de Campinas, 1995-11-04) SILVA, Francisco Hermes Santos da; SISTO, Fermino Fernandes; http://lattes.cnpq.br/8719624962833123
The objective of this study was to analyze two processes of intervention with a view toward operatory learning. In the first, the technique of cognitive conflict was applied and in the second, cognitive conflict associated with the formation of possibles. Our hypothesis was that the second process would present better results than the first, having seen that Piaget affirmed that the formation of possibles preceeds concrete operations. We worked with 20 children between the ages of 6 and 7 applying 10 sessions in two groups of 10 children. Comparative analyses of the data collected in the two interventions were made by taking into consideration five aspects: 1. a study of the interventions in terms of the acquisition of conservation of mass; 2. a study of the differences between IGC (Intervention Groups with Cognitive Conflict) and IGCP (Mixed Intervention Groups of Cognitive Conflict and Formation of Possibles) in terms of the indices and stability of operatory conduct; 3. a study of the differences between IGC and IGCP in terms of the types of operative arguments presented by the subjects; 4. analysis of the period of transition between non-operativeness and operativeness; and 5. studies of the differences between IGC and IGCP in terms of the operative arguments in function of the number of sessions with intermediary conducts. Our hypothesis was not confirmed from a quantitative point of view. However, while the intervention with conflict associated with the formation of possibles was not quantitatively demonstrated better than cognitive conflict, the technique was demonstrated valid as a pedagogical instrument in the acquisition of operativeness, since it presented satisfactory results with differences in relation to other groups being in terms of velocity of this acquisition and lesser production of operative arguments.

Análise da resistência a corrosão do aço carbono revestido com Al55-Zn após deformação mecânica e tratamento térmico
(Universidade Estadual de Campinas, 2001-01-12) BESERRA, Antonio Adelmo Freire; FREIRE, Célia Marina de Alvarenga; http://lattes.cnpq.br/6392994144210466
Analysis of the corrosion resistance of the 55AI-Zn coating on carbon steel after mechanical deformation and heat treatment The atmospheric corrosion resistance of 55%Al-Zn alloy coating on average is twelve times that of an equal thickness of galvanized coating. However, it has been shown that microcracks were observed at all levels of strain under simple uniaxial tension. Our research has been focused on determining the degree of corrosion experienced by these coatings after deformation under simple tension or bending and how much the heat treatment at '200 DEGREES' or '360 DEGREES' for 16h can influence the corrosion resistance of the coating. The coated sheet samples were strained to 10% or 15% engineering strain while another group of samples was bent to bend angles of '90 DEGREES' or '180 DEGREES'. The corrosion resistance of the samples was evaluated trhough Tafel extrapolation and electrochemical impedance spectroscopy methods. As a result, it was observed that both the straining and the bending of the coating reduces its corrosion resistance. After the heat treatment at '360 DEGREES' the samples strained to 10% or 15% recover their corrosion resistance, but the specimens bended to '90 DEGREES' or '180 DEGREES' recuperate only partially the corrosion resistance after the heat treatments.

Análise das características socioambientais na cidade de Belém/PA: um estudo da vegetação e clima urbano
(Universidade Estadual Paulista, 2017-01-24) RODRIGUES, José Edilson Cardoso; AMORIM, Margarete Cristiane de Costa Trindade; http://lattes.cnpq.br/6644811083291335
In recent decades the rapid growth of cities has caused substantial changes in the urban landscape, making start to generate their own environmental conditions and which are not always favorable to the population. One of the changes observed is the urban climate generation, because the city changes the climate mainly in micro and meso scale, through the surface changes causing the temperature rise, precipitation change, the winds flow modification and humidity. Another major change observed in the urban landscape is the reduction of vegetation cover, which performs various functions in the social, aesthetic and climatic context softening temperature and humidifying the in the urban environment and other. Interest in the study of the interaction between vegetation and urban climate of the city of Belém-PA, due to the reduction that vegetation has suffered and may have a significant impact on intraurban temperature that has seen an increase in recent decades. Thus, the main objective was to conduct a study relating to the reduction of the vegetation cover and the change in temperature patterns in the area that is the First League Balance of Belém-PA. The methodology embraced a conceptual theoretical analysis, with the method of the hypothetical-deductive analysis, adopting as a theoretical reference the urban climate system proposed by Monteiro (1976), emphasizing the thermodynamic subsystem. In proceedings conducted cartographical survey, use of thermal images, mapping of vegetation cover for lifting Vegetation Cover Index (VCI) and Vegetation Cover Index by Inhabitant (VCI / I), land use mapping, survey of temperature, time and space from INMET data, fixed mini-stations, transects and field work for records and observations. Thus, it was found that the loss of plant cover in Belém has been considered a historical process due to the city occupation process. Looking for VCI District, the DABEL (9.41%) had the highest rate, followed by DASAC (5.66%) and DAGUA (3.37%). The time temperature analysis showed a considerable growth trend over the decades and from thermal images the temperature of targets experienced fluctuations, especially in some neighborhoods located further north and south of League. Neighborhoods with little vegetation had higher temperatures compared to neighborhoods with large trees. Therefore, the loss of plant cover in the First League area associated with high temperatures has revealed a worrying environmental framework, particularly in neighborhoods that had VCI low and high density buildings which is directly reflected in the increase in temperature in these neighborhoods.

Análise de um modelo matemático de condução-convecção do tipo campo de fases para solidificação
(Universidade Estadual de Campinas, 2000-02-28) VAZ, Cristina Lúcia Dias; BOLDRINI, José Luiz; http://lattes.cnpq.br/6706768152701754
In this work we present results on existence and regularity of solutions of some conduction-convection models of phase-field type for solidification of either pure or impure (alloy) materiaIs. The essential characteristic of this models is that the solid fraction has a functional relation only with the phase field. For binary alloy solidification we are able to prove the existence of solutions only when the initial solute concentration is sufficiently small (that is, for dopant materiaIs.). The governing equations of the model are the phase field equation, the heat equation and/or solute equation coupled with a modified Navier-Stokes equations whose source term simulates the mushy region as a porous medium. Existence and regularity of the corresponding solutions are obtained as follows: firstly, the problem is adequately regularized and a sequence of regularized solutions is obtained using the Leray-Schauder's fixed point theorem. Then, by using compactness arguments, one proves that this sequence has a limit point which is a solution of the original problem. The corresponding regularity is obtained using bootstraping arguments.

An experimental set up for the study of tablets coating in a two-dimensional spouted bed that uses vibration of the perforated base to enhance the circulation of the particles was developed. An acrylic rectangular upper section (4x32 cm) with fixed 4x4 cm draft plates was adjusted over 3 different convergent sections (inclination 50') with 4x4 cm, 4x6 cm or 4x8 cm bases and contained 800g, 1100g or 1300g of tablets, Air (0,8 to 1,6 m3/min) forced by a 7,5 cv blower, was cooled down to 55°C and spouted this bed. The lenticular tablets (0,12g; 0,25g., 0,44g) were coated with a polymeric aqueous solution (11% solids). A two-fluid atomizer (air pressure 82,7 1kPa) was used, inserted laterally, near the bed base, and showed no influence on the movement of the particles. The experimental characterization of the tablets circulation rates was emphasized, using a magnet (0,4062 g) that followed the particles, activating a bobbin located at the upper end of the draft plates. The electric pulses were processed by a data acquisition sistem and the cicle time distribution curves were adjusted by the Modified Spline fit technique. The mean of the cicle time distribution creased with are increase of the bed load and the size of the tablets in all comparative tests. The vibration (10 Hz, 8 mm amplitude) reduced the mean of the cicle time distribution by more than 10%, and also decreased its variance. The vibration also affected the maximum pressure drop (40% reduction) and the minimum spouting velocity. The vibro spouted bed showed higher- adhesion efficency (73 to 88%) than the non-vibrated spouted bed (66 to 79%) in all equivalent situations and the complete coating of the smaller tablets demanded less processing time due to higher surface area circulation rate.

Análise do escoamento da soja brasileira através da simulação a eventos discretos
(Universidade Federal de Itajubá, 2017-10-16) LOPES, Harlenn dos Santos; LEAL, Fabiano; http://lattes.cnpq.br/4677862183830898; LIMA, Renato da Silva; http://lattes.cnpq.br/9161092505168234
Brazil, since 2013, is the largest exporter of soybean in the world. In 2016, Brazil exported 51.58 million tons of soybeans. This value corresponds to approximately 40% of the quantity exported worldwide. Even with lower production costs, the competitiveness of Brazilian soybean declines when the product get on the Brazilian logistics network, facing challenges to drain the production. This paper aims to present the construction and application of a simulation project to support strategic decisions of the Brazilian soybean logistics through the simulation of discrete events. The paper's contribution is due to the use of simulation of discrete events applied to a logistic system, with a greater level of comprehension studied and the high number of interrelated variables. For the study, Brazil was divided according to its soybean production, which results in 19 producing areas coming from a minimum level of microregions. These regions are the origins of the system. For each source, 20 routes from North to South of the country were designed, destined to the current soybean export ports, by the main transport axes, either constructed or projected. The decision-making process is based on the costs of the routes and the availability of the ports. The final destinations are the ports of Shanghai and Hamburg. The model was validated, and adequately represents the studied system. A number of 39 scenarios were simulated for the system, divided in 13 scenarios per year, considering projections for 2015, 2017 and 2026. Operational analyzes of logistics configuration and comparative analyzes based on actual costs are performed. At the end of the simulations, scenarios 1, 2, 6 and 7 are the alternatives that best reduce the logistic costs of the studied system and that the railroads that lead to the ports of São Francisco do Sul and Ilo (F2 and F4 respectively) are not attractive in the analyzed context.. Scenarios 2, 6 and 7 direct the decision to invest in the Araguaia-Tocantins Hidrovia (HAT) and in railroads linking the cities of Maringá and Cruz Alta to the Ports of Paranaguá and Rio Grande, F1 and F3, respectively.

Análise do processo de difusão atômica no estado sólido em sistemas unidirecionais e radiais
(Universidade Estadual de Campinas, 1991-03-14) MOREIRA, Antonio Luciano Seabra; SANTOS, Rezende Gomes dos; http://lattes.cnpq.br/8824197696621614
In this work an analytical method is proposed to study diffusion pro¬cess in the solid state in binary systems consisting of only one phase with unidirectional, cylindrical and spherical atomic fluxo Initially a literature survey is carried out regarding some of the most important methods applied to diffusion process in these systems. The method is developed from the differential equation which treats this process in systems with unidirectional atomic flux, that is modified by geometric correlation and convenient changes of variables. The modified differential equation is solved by using a well known exact solution based on the error function and equations are obtained to analyse both the position of the diffusion interface as a function of time and the concentration profiles as a function of the position and time. The predictions furnished by the analytical method are compared with numerical results. A comparative study of diffusion process in planar, cylindrical and spherical geometries is ais o presented. Finally possible applications of the proposed method to the solution of practical problems are discussed.

The drying of annatto seeds (Bixa orellana L.), type Red Piave, was studied in a fixed bed dryer. The optimal conditions were obtained to minimize the bixin losses and to obtain the final moisture content of seeds in the adequate lovels for conservation and quality maintenance. The bixix and the final moisture contents were studied as a function of the operational variables of the drying process. The termodynamic behavior of the seeds during the process of moisture desorption was verified by the static gravimetric method, using saturated salt solutions to maintain atmospheres with relative humidities in the range from 7 to 75%, at temperatures between 15 and 80ºC. GAB medel was used to fit the experimental data and the three parameters of GAB equation were evaluated. The Clausisus-Clapeyron equations was applied to obtain the net isosteric heats of sorption, using the desorption isotherm¿s data. It was verified that the annatto seeds can be conserved with higher stability in atmospheres with relative humidity of 60% in the range of temperatures studied. The quantification of the influences of the inlet variables of the process in the final moisture and bixin contents of the seeds and the identification of the optimal point for the process was accomplished by techniques of fractional factorial design, response surface methodology, canonical analysis and desirability function. Its was verified that the final moisture content of the seeds can be estimated by a second order polynomial model as a function of the is temperature and mass flow rate and of the dryng time, and that final bixin content is significantly influenced only by the process time, being described appropriately by linear model.

This research aimed to demonstrate the theoretical and methodological importance of Archival Science and institutional archival services as areas, respectively, of knowledge and professional indispensable to the computerization of Brazilian public institutions. The proposal was carried out based on the mandatory implementation of electronic administrative processes, set out in Decree no. 8,539, of October 8, 2015. For this, a broad literature review is presented on the theoretical and methodological knowledge developed in Science Archival, over time, under which discussions on the qualities and characteristics of archives were theoretically inserted and records (digital and non digital) and their constituent parts; sets of record management procedures and the notion of life cycle, at the international and national levels; and the theoretical development on digital records that results in the creation of conceptual requirements norms that guide the development of computerized systems in which such records are produced, such as the Requirements Model for Computerized Systems of Archival Document Management - e-ARQ Brazil, published by the National Council of Archives (CONARQ). Then, the institutional scenario of UFPA and its Central Archive is presented, which makes it possible to understand the scenarios crossed by the archival area of the institution until its consolidation as leadership of the project to implement the Electronic Administrative Process (PAE) at UFPA. An adherence analysis of the UFPA’s electronic process system, the Integrated System of Patrimony, Administration and Contracts (SIPAC), was carried out to the second version of e-ARQ Brasil, where it was possible to identify that the referred system presented 69% of adherence established mandatory requirements. Finally, it was concluded that the theoretical knowledge of Archival Science is legitimately indispensable to produce digital records to occur in order to guarantee better conditions of reliability, authenticity and long-term access, and that the SIPAC System, implemented under the leadership of from the UFPA’s Central Archive, showed a high level of adherence to e-ARQ Brasil 2. Finally, the research provides society and UFPA with a consistent analysis that helps the University to make decisions about aspects that can be improved in the SIPAC-UFPA.

A arte de narrar: da constituição das estórias e dos saberes dos narradores da Amazônia paraense
(Universidade Estadual de Campinas, 2000-12-13) BENTES, Anna Christina; ALKMIM, Tânia Maria; http://lattes.cnpq.br/8437404856512094; KOCH, Ingedore Grunfeld Villaça; http://lattes.cnpq.br/9851642920435372
Taking into account that the act of narrating presents a necessary meta-discoursive reflexion about what is being narrated and that narrative presents a patteming or a "schematism" responsible for maintaining the narrative paradigm order, this study describes how narrators from Brazilian Amazon region configurate narrative tradition in two different ways. The first way called "folk-tale" is characterized considering the fact that narrators, when telling their stories, choose (i) to present frxed plots, which are commonshared, (ii) to construct a high degree of distance from what is being narrated, (iii) to necessarily present narrative structured in tenns of "conflict/resolutionn and {iv) to inscribe narrative sequences in a wondering discoursive domain. Narrators choose to configurate oral tradition in a way called "oral story" when they (i) do not present a frxed plot, reconstructing oral traditional narrativas in a personal way (ii) express their evaluations about what is been narrated, (iii) structure narrativa not necessarily in tenns of "conflict/resolution", but in a way that "resolution" category is not obrigatory, (iv) present the characters through a subjective perspectiva, showing their internai processes (feelings, thoughts etc.) and (v) inscribe the narrative sequences in other fictional domains. The narrativas analysed in this thesis were collected by a group of researchers from Universidade Federal do Pará and were published in three volumes. The analysis of thirty narrativas allows us to conclude that narrators can linguistically configurate narrative tradition in two ways: the first one, characterized by the fact that narrators privilege when telling their stories the dimensions of repetition and stability; the second one, characterized by the fact that narrators privilege when telling their stories the dimensions of difference and instability.

The objective of the present study was to characterize some aspects of the extracellular matrix components of the alar and septal cartilage of the nose of swine and to examine the histological and histochemical aspects of the two types of cartilage. The kaotropic agent Gu-HCl was used to extract the matrix components. The predominant glycosaminoglycan in the two caitilages was chondroitin sulfate. After ultracentrifugation, the D4 fraction of the septal and alar cartilages was fractioned on DEAE-Sephacel using na NaCl gradient. SDS-PAGE analysiys showed similarities between the two cartilages, with the presence of fíbromodulin, decorin and binding proteins. Only the septal cartilage presented the 115 kDa component, which possibly appears as 30 kDa subunits after the action of the reducing agent. The glycosaminoglycan populations were determined by fractionation on Sepharose CL-6B followed by analysis of the samples on the agarosepolyacrilamide gel. The two cartilages presented a strongly polydispersed population, which was less uniformly polydispersed in the septal than in the alar cartilage. AD2 fractionation on DEAE-Sephacel and sample analysis by SDS-PAGE and agarosepolyacrylamide electrophoresis showed the presence of the small proteoglycans biglycan and decorin, possible associated with the large proteoglycans. The septal cartilage presents chondrocytes roughly arranged in rows accompanyng the widest axis of the cartilage, whereas the alar cartilage presents chondrocytes characteristically arranged in isogenic groups. Histhochemistry was performed usisng Xylidine Ponceau for total proteins, Picrosirius-Hematoxylin for collagen, Toluidine Blue for total glycosaminoglycans. And alcian blues, pH 2.5 and pH 1.0, for sulfated and carboxylated glycosaminoglycans. Total glycosaminoglycans are more cleary visible in the territorial matrix, whereas total proteins are more cleary visible in the interterritorial matrix. The collagen of the septal cartilage is roughly organized along the longitudinal axis of the specimens between the chondrocytes rows.

Banco Interamericano de Desenvolvimento e Política Urbana no município de Belém: tensões e compatibilidades no modelo de gestão de cidades e no discurso da participação social

This thesis aims at learning the meaning of the Inter-American Development Bank (IDB) multilateral financial aid for Latin American countries, particularly Brazil, and tries to identify how the bank operates, through several mediations, in the defense of continuing capital accumulation. Our research identified that IDB operates not only as a policy financing agent, but mainly as the general intelligentsia of the interests of the elite by prescribing management models for: a) federal governments through the Country Documents and Strategy Documents (mainly about State reform themes connected to the neoliberal recommendation of structural adjustments to facilitate – among other things – the payment of the foreign debts by the central governments); b) municipal governments, through the dissemination of a city management model, urging local authorities to take over the execution of social policies with efficiency and economy in the public social expenditures, and implement sectoral and focused policies (for the “urban poor”), while preparing, at the same time, the city infrastructure in order to attract corporate investors besides forming “partnerships” with society (enhancing social participation) and private initiatives. On the other hand, this thesis also analyzes the city management model, based on the democratic perspective of the Urban Reform (specially the city democratic management principle), which is contrary to the neoliberal model recommended by IDB, thus favoring working classes factions, validating democratic processes (direct democracy) in the defense of citizenship, referenced by socialist ideologies. Such democratic model started to be widely used in Brazil, particularly when some municipalities started to be run by Workers Party mayors (as of 2000). At that moment, there was some expectation regarding the creation of proposals incorporating the political advances in the social sector as provided in the Federal Constitution of 1988. In the city of Belém, State of Pará, a left winged front run by the Workers Party won the elections in 1996, renewing its mandate until 2004. At the level of government planning, the Municipal Authority of Belém claimed for a political management connected to the city management democratic model, based on the principles of social participation and state democratization. Through a project financed by IDB (Habitar Brazil Program – IDB), the Local Development Plan “Riacho Doce” and “Pantanal”, the city had to comply with a series of demands, such as the signature of an Acceptance Contract by 80% of the users. Since the city authorities favored an alternate planning, which enhanced the participation of the local residents in all stages of the project, the research tried to identify points of conflict and of compatibility between the city management models and the social participation notion (a neoliberal proposal by IDB) of democratic base. The results indicate that the city management democratic model discourse presents some elements of conflict (contrary trends), mainly expressed by the proposals for the universalization of rights, inter-sectoral policies, and allusions to socialist ideals. Elements of compatibility were also found (adaptation of the Plan in order to guarantee the funds), but the overall result appointed to more points of difference than of compatibility between the neoliberal and the democratic agendas.
