Análise de desempenho de um fogão solar construído a partir de sucatas de antena de tv

Given the growing environmental crisis caused by degradation, mainly due to the use of polluting energy sources, increasing the growing use of renewable energies worldwide, with emphasis on solar energy, an abundant supply and available to everyone, which can be harnessed in several ways: electricity generation; dehydration of food; heating, disinfection and distillation and cooking. The latter has as its primary feature the viability of clean, renewable energy for society, combating ecological damage caused by large-scale use of firewood for cooking foods, use in tropical countries with high solar radiation, and has funding NGOs throughout the world with the goal of achieving low-income population. The proposed project consists of a solar cooker for concentration, working from the reflection of sunlight by a hub that they converge to a focal point at the bottom of the pot, getting lots of heat. The solar cooker under study consists of two elliptical reflecting parabolas made from the recycling of scrap TV antenna, having 0.29 m² of surface area for each antenna, which were covered by multiple mirrors of 2 mm thick and mounted on a metal structure, with correction for the mobility of the apparent movement of the sun. This structure was built with the recycling of scrap metal, possessing a relatively low cost compared with other solar cookers, around US$ 50.00. This cost becomes negligible, since that will involve a great benefit to not have fuel costs for each meal, unlike the use of gas or firewood for cooking food. The tests show that the cooker has reached the maximum temperature of 740 ° C, for boiling water in an average time of 28 minutes, cooking various types of foods such as potatoes, rice and pasta in an average time of 45 minutes and still going as a solar oven, making pizza baking and meat. These cooking times do not differ much from the cooking times on a gas stove, it becomes the solar cooker as a good consumer acceptance, and furthermore not to deliver the same gases that can poison the food as with the wood stove. Proves the viability of using the stove to cook or bake in two daily meals for a family, still presenting a position to improve his performance with the addition of new materials, equipment and techniques

Efeitos de fontes de nitrogênio e de modos de aplicação do adubo fosfatado (32P) sobre a porcentagem de utilização do fósforo do superfosfato simples pelo trigo (Triticum aestivum L.)

No programa de pesquisa a respeito da adubação da cultura de trigo, utilizando isotopos (32P e 15N), o plano do ano 1971/1972 tinha, entre outros objetivos, a finalidade de determinar a porcentagem de aproveitamento do fósforo pelo trigo, em função do modo de aplicação e interação com fontes de nitrogênio. Oexperimento foi instalado em solo pertencente a ordem Ultisol e grande grupo Podzólico Vermelho-Amarelo (Pelotas-RS), contendo 9 ppm de P. Os adubos nitrogenados: sulfato de amônio, uréia e nitrato de amônio, na dose de 120 kg/ha, foram aplicados metade no plantio (ao lado e abaixo das sementes) e metade em cobertura, na fase do perfilhamento. O fósforo radioativo, na forma de superfosfato simples, foi aplicado na dose de 30 kg P2O5/ha de duas maneiras: junto com as sementes ou junto com o adubo nitrogenado aplicado no plantio. Amostras de plantas de trigo foram coletadas entre perfilhamento e espigamento e determinaram-se os pesos de matéria verde e seca, as porcentagens de P total e de P proveniente do fertilizante contidos na matéria seca e a porcentagem de utilização do fósforo aplicado (% UP). Pode-se concluir que a aplicação de nitrogênio é necessário para se obter maio res % UP, mas não há diferenças entre as fontes. Os modos de aplicação do fósforo não diferiram entre si quanto a % UP.

Formação continuada de professores que ensinam matemática: o papel do ábaco na ressignificação da prática pedagógica

The present dissertation performs a study about abacus part on the continuous education of Elementary School s Mathematic teachers on what concerns the basic operations of addition and subtraction with (re)unification by using the manipulative and/or informatical abacus. Therefore, the research intends to answer the following question: How does a teacher reframe the pedagogical practice while teaching the Decimal Numeral System and the conventional operations of addition and subtraction with (re)unification through manipulative and informatical abacus? In order to do so, we rely ourselves on the Guy Brousseau s Theory of Didactic Situations (TDS) from 1996 that affirms the necessity to trace a way in accordance with the teaching situations that lead the student s learning; and on the work of Pierre Lévy (1993), in which the poles of communication oral, written and virtual create three ways of communication through which the learning process happens. The methodology of this paper was based on the Strategic Research-Action of Franco (2005). The didactic sequence was elaborated in accordance with TDS and used the manipulative and informatical abacus as didactic resource. With the application of the didactic sequence, it was verified that the continued formation of Elementary School s teachers concerning the operations of addition and subtraction on the initial years/levels is pertinent once it has been observed some difficulties of the teachers concerning this mathematical subject. Besides, the analysis of the didactic sequence has allowed one to realize that teachers had some difficulties concerning the numeric representation with order zero, the resolution of operations of addition and subtraction using the manipulative and informatical abacus and the realization of (re)unification on the subtraction with meaning. These observations has been discussed with the teachers and, after that, it has been done some didactic-methodological routings of the operations of addition and subtraction with re(unification) that contributes with the teaching and learning process.

Ensino por investigação: contribuições de um curso de formação continuada para a prática de professores de ciências naturais e biologia

Normally initial teacher training has not been sufficient to provide all the tools for an updated and efficient teaching practice. It is presented here one of the ways of working the completion of the initial training through a course of continuing education. This course is based on inquiry teaching which is considered an important teaching strategy for science education. This kind of teaching enables improvement of students reasoning and cognitive skills, the cooperation among them, the understanding of the nature of scientific work, and the motivation to think about the relationship between science, technology, society and environment. For this dissertation a course of continuing education based on this approach was followed in order to evaluate which contributions it can bring to the teaching practice. The course was followed based on three stages: on the first there was a questionnaire and an informal interview; next it happened through participant observation with audio and visual aid; the third stage happened through semi structured interview. The collected information was analyzed based on Content Analysis. An inquiry teaching pedagogical material was produced for the course including some examples and applications of this approach. The aim of the material is that it can be a support for the teachers after de course. The results allowed seeing that the course was very useful, different from the traditional and the teachers that put the approach to use found it to be very positive. Thus it can be said that some of the teachers who participated will try again to apply it, try to contextualize more the teaching situations with the students day to day life, as well make them more active and critic. We can also gather from the study, that the inquiry teaching is a very different tool from what the teacher was taught and is accustomed to use and the theoretical comprehension, acceptance and practice change is a complicated process and demands time

Um breve estudo acerca do cotidiano do trabalho de produtores rurais: intoxicações por agrotóxicos e subnotificação

Pesquisas na área da Saúde no Trabalho têm revelado a preocupação com os agravos à saúde de trabalhadores rurais decorrentes da utilização de defensivos agrícolas. Diante disso, este estudo objetivou conhecer o cotidiano de trabalho de produtores rurais de uma cooperativa agrícola localizada no interior do estado de São Paulo, bem como avaliar a exposição deles quando da utilização de agrotóxicos no desenvolvimento de suas atividades. Esperamos, com base nos resultados, estar contribuindo com discussões sobre o tema relacionado à saúde dos trabalhadores no contexto considerado. Para coleta de dados, utilizamos entrevistas semi-estruturadas, aplicadas de formas individual e coletiva. Participaram do estudo cinqüenta produtores rurais que desenvolvem atividades nas lavouras de café, soja, trigo e milho. Os dados foram agrupados em cinco categorias e analisados qualitativamente. Os resultados expõem as características da atividade agrícola na região, a utilização dos equipamentos de proteção individual, as técnicas no uso dos agrotóxicos, o sofrimento psíquico e a produção rural e maneiras de lidar com as situações de intoxicação e alertar os órgãos competentes para o problema da subnotificação.

Modos de ler, formas de escrever a literatura enquanto objeto da ficção de Enrique Vila-Matas

Este trabajo busca analizar cómo algunos aspectos presentes en la obra de ficción del escritor catalán Enrique Vila-Matas permiten pensar las prácticas de la escritura literaria contemporánea. A partir de una forma híbrida que reconsidera las relaciones tanto entre los géneros como entre los discursos crítico y de ficción, la obra del autor se propone reflexionar sobre sus propias posibilidades en el contexto sociocultural contemporáneo. De este modo, a través de una ficción que muchas veces adquiere los atributos del ensayo, Vila-Matas trae al centro de sus enredos la discusión de cuestiones relacionadas con los impases de una escritura que vuelve su atención para el destino de una tradición literaria desvinculada de los preceptos meramente mercadológicos contemporáneos. Su manera crítica de abordar la literatura y la experimentación en busca de nuevas posibilidades permite asociarlo tanto a Laurence Sterne como al proyecto literario de Jorge Luis Borges. Estos autores tienen propuestas que tratan de superar los límites del texto, ya que ahí está el deseo de acogerse a la ficción para demostrar la inestabilidad de los elementos de una cultura, apropiándose y desestabilizando los discursos y las claras distinciones entre los saberes. En este sentido, las diversas formas en que Vila- Matas se apropia de los textos de otros y construye una obra de carácter fuertemente intertextual denuncian jerarquizaciones y modos de circulación de textos que permiten aproximarse de la tensión existente entre temas como influencia, citación, prácticas de lectura y escritura

O impacto das tarefas de aprendizagem mediadas pela lousa digital interativa na motivação situacional de aprendizes de inglês

Some authors have suggested that learning tasks conducted in L2 classes can motivate learners in different ways. Similarly, Interactive Whiteboards (IWB) have already been linked as drivers to engagement and enthusiasm in L2 classes, which may cause some impact on affective variables that influence learning (e.g. motivation). This crosssectional mixed-methods study aims to understand how situational motivation caused by learning tasks mediated by the IWB impact participants. We seek to answer the following research questions: (1) How does motivation as a personality trait of the learner relate to his/her additional language learning performance?, (2) How does the type of learning task mediated by the IWB impact the learner s motivation?, (3) How does motivation vary along the learning task mediated by the IWB? and (4) What is the relation between the learning task motivation and the learners perception about the task mediated by the IWB? Data collection lasted four months with 29 learners from a private language school. The instruments used were the following: (a) an initial questionnaire (adapted from the Attitudes/Motivation Test Battery by GARDNER, 2004), (b) situation-specific on-line scales to assess learners motivation in three moments: before, during and after the task, and analyze how motivation varies along the task; (c) class observations and field notes resulting from these observations, (d) participants end-of-course grades to understand the connection between academic success and their motivational profiles and (e) a final questionnaire with the qualitative purpose to know learners perceptions about the tasks mediated by the IWB. Our theoretical framework is based on Task-Based Learning and cognitive aspects present in tasks (WILLIS, 1996; SKEHAN, 1996), theories on motivation and second language learning (GARDNER, 2001; DÖRNYEI e OTTÓ, 1998; DÖRNYEI, 2000; 2002) and conceptions about L2 learning mediated by technology (GIBSON, 2001; OLIVEIRA, 2001; MILLER et al, 2005). Our results do not point out to a significative correlation between learners end-of-course grades and their motivational profiles. However, they indicate that there is some variability in situational motivation along the tasks, even among learning tasks from the same type. Furthermore, they show that learners report different perceptions for each learning task and that the impact of the IWB on participants did not have a large proportion

A ferramenta VoiceThread em uma abordagem hibrida: o desenvolvimento da produção oral e da habilidade de noticing na aprendizagem de inglês como L2

VoiceThread (VT) is a collaborative and asynchronous web 2.0 tool, which permits the creation of oral presentations with the help of images, documents, texts and voice, allowing groups of people to browse and contribute with comments using several options: voice (microphone or cell phone), text and audio-file or video (webcam) (BOTTENTUIT JUNIOR, LISBÔA E COUTINHO, 2009). The hybrid experience with VoiceThread allows learners to plan their speech before recording it, without the pressure often existent in the classroom. Furthermore, the presentations can be recorded several times, enabling students to listen to them, notice the gaps in their oral production (noticing) and edit innumerous times before publishing them online. In this perspective, oral production is seen as a process of L2 acquisition, not only as practice of already existent knowledge, because it can stimulate the learner to process the language syntactically (SWAIN, 1985; 1995). In this context, this study aims to verify if there is a relation between the oral production of the learners more specifically the grammatical accuracy and the global oral grade and their noticing capacity, how the systematic practice with VoiceThread, in a hybrid approach, can impact the learners global oral development, their oral production in terms of fluency (number of words per minute), accuracy (number of errors in hundred words), and complexity (number of dependent clauses per minute), and on their noticing capacity (SCHMIDT, 1990; 1995; 2001), that is, the learner s capacity of noticing the gaps existent in their oral production. In order to answer these research questions, 49 L2 learners of English were divided into an experimental group (25 students) and a control group (24 students). The experimental group was exposed to the hybrid approach with VT during two months and, through a pre- and post-test, we verified if this systematic practice would positively influence these participants oral production and noticing capacity. These results were compared to the pre- and post-test scores from the control group, which was not exposed to VT. Finally, learners impressions in relation to the use of this tool were also sought through a questionnaire applied after the post-test. The results indicate that there is a statistically significant correlation between the learners speech production (accuracy and global oral grade) and their noticing capacity. Besides, it was verified a positive impact of VoiceThread on the learners speech production variables and on their noticing capacity. They also reveal a positive reaction by the learners in relation to the hybrid experience with this web tool

Análise textual dos discursos: responsabilidade enunciativa no texto jurídico

This investigation aims at describing, analyzing and interpreting the Commitment in Initial Petitions, which is a genre circumscribed in the judicial domain. For this purpose, we have chosen sections, facts as found and relevant law , sections of the petition, with the understanding that, in this way, respectively, the narration of events, which gives margin to the propositioning to the judicial action, and the exposition of the law that upholds the author s intention. We base our discussion on the field of Linguistics, more precisely, Textual Discourse Analysis (TDA), whose theoretical basis is derived from Textual Linguistics (TL) and Enunciative Linguistics. We foreground, particularly, the way in which the author of texts, objects of analysis, use discursive strategies that evidence ER. The relevance of this study, then, is in the formation of a critique of the judicial text, as it conceives of a dialogical approach to the point of view, raising not only questions about the way in which a linguistic instance conceives an object of discourse, but also considering questions of language inherent to technical writing and, in this aspect, contributing to the work of those operating in Law about the many ways ER is formed in the body of a petition. We selected two categories to analyze that, according to Adam (2011), characterize the degree of ER in the textual material of the propositional enunciations: the different types of representation of speech and the indications of profile of mediators. In this sense, with this task as an objective, we base our study regarding point of view on Rabatel (2003, 2009a, 2010) with relation to the enunciative approach, including the study of PDV in polyphonic and dialogical theoretical framework to study the ER from different types of speech representations that conceive forms of transmission of discourse and the role of the enunciating subject, mainly the responsibility and the prerogative by the propositional contents. In the same way, intending to study the indications of the mediator profiles, we observed the postulations of Guentchéva (1994, 1996), which develop the notion of mediative grammatical categories, of which permit the linguistic marking of distance and engagement of the enunciator with regard to the information expressed. The methodology we adopted was based on qualitative research, of an interpretive and introspective nature, in light of the fact that his study focuses on processes and strategies underlying language use. The corpus of the research is comprised of Initial Petitions, which gave rise to actions originating in the Civil Court of Currais Novos County RN. The data analysis shows that an object of discourse is always perspective oriented and presents the point of view of one or more enunciators. Consequently, the producer of a text, using the PDV of other enunciators, influences and establishes the argumentative orientation of the text. In the same way, it evidences the relevance of the use of mediated constructions in the judicial text, as they function as strategies attenuated to the responsibility of the producer of the text with what is said, and at the same time points to a discourse of authority through the entrance of the sources of law. Moreover, it reveals the documental and international importance of this practice, at the same time that it exposes the compositional and normative difficulties with regard to legal and linguistic aspects

Liberdade e negação da vontade: análise do ser-livre como representação e na angústia

Common understanding about what freedom means has always been more or less related to the power to realize something intended, desired, a capability. Therefore, being free is commonly interpreted under the concept of free-will and the category of possibility to act. Although there are predecessors in History of Philosophy, Schopenhauer refuses the thesis of free will proposing otherwise the denial of willing (to live) as the ultimate possibility for human freedom, if not the only one left. The thesis that would make him famous was deeply misunderstood and so miscarried somewhat due to the way it was many times presented by the means of exotic examples wrapped in a mystical mood besides exaltations to Eastern traditions, which may satisfy anthropological curiosity instead of being capable to satisfy the reader in a philosophical way. It seems to result from Schopenhauer s thought a kind of pessimism against life. Otherwise, typical readings on the Schopenhauerian thesis are found full of inconsistencies once closely regarded, which blame does not belong to the author but to his interpreters. A new reading about the denial of willing as the ultimate possibility for human freedom demands a criticism on the inconsistencies and prejudgments deep grounded. For this, we firstly clarify the ways of understanding the willing nothing , which cannot be reduced to the mere refusal or conformism, being instead positively understood as a special manner of willing: the admission of oneself for the sake of one is. A few more than a century later The world as will and representation came to light, Heidegger proposes in his fundamental ontology that the proper being-free concerns to originary decision by which, in anguish of being suspended in nothingness, Dasein renders itself singular as the being who is in-a-world and to-death, concluding that the ultimate possibility of freedom is being-free-to-death. Developing the hypothesis that freedom, properly understood, concerns to nothingness as to indeterminate possibilities, we seek for a dialogue between Schopenhauer s thought and existential philosophy aiming to reconstitute and overcome Metaphysics tradition turning the question about freedom into a matter of Ontology. From the factual existence perspective, as we must show, every human activity (or inactivity) is ordinarily mediated by representations, in which me and world appear as distinct entities. So, each one among determininate individuals finds itself connected to the things in the world by interest, which proper concept must be sufficiently explored. Starting from this point, we may proceed to detailed analysis of usual representations of freedom aiming their destruction by Ontology and then reaching existential thesis according to Kierkegaard and Heidegger. Turning back to the analysis of Schopenhauer s work, we conclude existential understanding of freedom as will-to-be can also be found in Schopenhauer. In this way, denial of willing means ultimate freedom once the Will turns back to its own essence by suppressing the world as representation, which means the originary absolute indetermination of the extreme possibility to-be

Foucault e a (bio) política: possibilidades e metamorfose de um conceito

The fundamental question developed in this research is to consider the possible meanings of biopolitics in the thought of Michel Foucault. In the first chapter of this study seeks to examine the rationality of biopower. It is able to show the rationality of acting as a social machinery for the manufacture of the subjectivity of individuals, biopolitics as a producer of bodies and subjectivity. The theme of biopolitics appears as inspiration of Nietzsche's metaphor of war. The idea that history is the war for dominance of the bodies. In the second chapter, the (bio) political will and political thought of resistance, fighting criticism as an attitude of revolt of the subject before his condition subjugated. The biopolitical here is intended as a conceptual tool for reading the thought / Foucault's work. A resistance that can be thought of as a biopolitical as a "refractoriness reflected". The third chapter will seek to show how the Foucault argues that power was already present the ethics of self-care. If the subject is a product, is captured by the discourse of biopower that manufactures its subjectivity, self care, it's time to think about the inner contents. Self care is something that offers resistance, as a possibility to think that these contents are constructed historically, and that therefore it is possible to reestablish the self-care is a policy of fighting these sedimented content that promotes colonization of the subjects. You can move from ruler to ruled itself, although this pursuit of liberty is always unfinished, always be a tension, a desire for freedom that can be undertaken not as a state, but at least the minimum and temporarily in other forms of existence, and other ways of relating, other ways of sociability, friendship, sexuality

Aspectos dinâmicos da água versus álcool e acetona por técnicas de congelamento

Water still represents, on its critical properties and phase transitions, a problem of current scientific interest, as a consequence of the countless open questions and of the inadequacy of the existent theoretical models, mainly related to the different solid and liquid phases that this substance possesses. For example, there are 13 known crystalline forms of water, and also amorphous phases. One of them, the amorphous ice of very high density (VHDA), was just recently observed. Other example is the anomalous behavior in the macroscopic density, which presents a maximum at the temperature of 277 K. In order to experimentally investigate the behavior of one of the liquid-solid phase transitions, the anomaly in its density and also the metastability, we used three different cooling techniques and, as comparison systems, we made use of the solvents: acetone and ethyl alcohol. The first studied cooling system employ a Peltier plate, a device recently developed, which makes use of small cubes made up of semiconductors to change heat among two surfaces; the second system is a commercial refrigerator, similar to the residential ones. Finally, the liquid nitrogen technique, which is used to refrigerate the samples in a container, in two ways: a very fast and other one, almost static. In those three systems, three Beckers of aluminum were used (with a volume of 80 ml, each), containing water, alcohol and acetone. They were closed and maintained at atmospheric pressure. Inside of each Becker were installed three thermocouples, disposed along the vertical axis of the Beckers, one close to the inferior surface, other to the medium level and the last one close the superior surface. A system of data acquisition was built via virtual instrumentation using as a central equipment a Data-Acquisition board. The temperature data were collected by the three thermocouples in the three Beckers, simultaneously, in function of freezing time. We will present the behavior of temperature versus freezing time for the three substances. The results show the characterization of the transitions of the liquid

Desempenho de pacientes com acidente vascular encefalico em testes de reconhecimento de tividades de vida diaria com frequencia autocontrolada e pre- determinada Luciana Protásio de Melo Natal 2009

The stimulation of motor learning is an important component to a rehabilitation and type of practice used is de basic importance to Physiotherapy. The motor skills are the types more basic of behavior that subjects must acquire throughout its lives and observational learning one of forms for its acquisition. Objective: This study aimed to compare performance of patients post- stroke on test of recognition of activities of day life using self-controlled and externally determined practice. Intervention: Forty subjects had been evaluated, 20 stroke patients (the mean age was 57,9?}6,7 years, schooling 6,7?}3,09 years and time of injury 23,4?}17,2 months) and 20 health subjects (the mean age 55,4?}5,9 years and schooling 8?}3,7 years). All was evaluated about independence functional (FIM) and cognitive state (MMSE), and patients were also evaluated about neurologic state (NIHSS). Later, all realized a recognition of activities of day life test (drink water and speak to telephone) on self-controlled (PAUTO and CAUTO) and externally determined (P20 and C20) frequency. The stroke subjects also were examined for a three-dimensional system of kinematic analysis, when they have drink water. The statistic analysis was realized for chi-square and t Student tests. Results: This was not difference, about number of rightness, between groups of self-controlled and externally determined practice (p0,005), and also not between patients and control groups (p0,005). Patients mean velocity (PAUTO: 141,1mm/sec and P20: 141,6mm/sec) and peak velocity (PAUTO: 652,1mm/sec and P20: 598,6mm/sec) were reduced, as well as the angles reached for elbow (PAUTO: 66,60 and 124,40; P20: 66,30 and 128,50 extension e flexion respectively) regarding literature. Conclusions: The performance on recognition of activities of day life test was similar between on self-controlled and externally determined frequency, showing both technique may be used to stimulate motor learning on chronic patients after stroke

As orquestras invadem as salas de estar: redefinição dos padrões e espaços para a escuta musical no Rio de Janeiro (1926-1931)

In the late nineteenth and early twentieth century, a series of technical innovations have been commercially and widespread on some urban groups everyday, in Brazil. Some of these technological innovations have played an important role in large-scale distribution of artistic works, which until then had an extremely limited potential for diffusion. Development of devices that can record and play music has been mechanically inserted into this logic, while the gramophones, phonographs, cylinders and discs became popular. By this time a new moment for production and consumption of music had started. Especially since the begging of electrical system for registration and production of sounds, this process bought important meaning to the way some peoples in Rio would leasing and sense music, besides it had contributed substantially to changes in the spatial references of these individuals

Ocidentalização, territórios e populações indígenas no sertão da Capitania do Rio Grande

The objective of this work is to understand some of the modifications caused for the phenomenon of the westernization in the hinterland of the Capitania do Rio Grande e in the life of the indians populations that inhabited there during the Colonial Period. We break of the quarrel of Serge Gruzinski concerning the westernization, understood while immersed phenomenon in the context of the expansion of the commercial capitalism and that, for the imposition of the culture occidental person to the alteridades of the New World, emprende the conquest of its territories, bodies and souls. The space clipping has covered the hinterland of the Capitania do Rio Grande, specifically the colonial territory of the Freguesia da Gloriosa Senhora Santa Ana do Seridó. The chosen chronological limit for the research corresponds to the Colonial Period and part of the Imperial one. However, the emphasis falls again on the period that it initiates in 1670, year of the oldest concession of would sesmaria known until the moment in the hinterland of the Rio Grande, extending itself until the decade of 1840. Sources of written by hand nature, cartographic printed and compose the used document roll: official correspondence and legislation, petitions of would sesmaria, inventories post-mortem, justifications of debt, registers of parish, maps, action civil court jurisdiction, notes of notary's office, land landmarks. We take the method, analyzed for Carlo Ginzburg, to cross these sources between itself and to detect its implied particularitities and ideas in the space between lineses, but, attributing it status to they of a colonial speech, fruit of the bureaucracy of where it was originated and of the social place of who produced it. We look for to demonstrate, throughout the work, that the phenomenon of the westernization desestruturou the aboriginal societies and its habitat, constructing, over its rubbles, a colonial territory that found in the cartography of the Freguesia de Santa Ana an efficient instrument of control of the space and the population. On the other hand, if the imposition of the culture occidental person exterminou great part of the native population that inhabited the hinterland of the Rio Grande, the remainders of these indians and the mestizos of descending them had survived in diverse ways in the freguesia: in the condition of captives of war or in regimen of servile work, as living or assistants in the farms, populations and village; rambling without route in the fields and the population spots; as mediating agents between the world occidental person and the native, exerting military or civil positions and still appealing to Justice in search of its rights of inheritance. Experiences of slavery, servitude, errância and mediation, but, also of resistance, adaptation, mestization in the Freguesia de Santa Ana
