Incorporação de lodo de esgoto na massa cerâmica para fabricação de tijolos maciços: uma alternativa para a disposição final de resíduo

The disposal of sewage sludge is a growing problem face up to management of sanitary sevices. Otherwise, because its making process characteristic, the Ceramic Industry can tolerate the presence of this wastes as raw material. This study has as object to confirm the use of the sewage sluge in the Ceramic Industry like a sustentable alternative for its disposal. Futhermore, this study quests to evaluate the maximum proportion for incorporation of sludge wich result in technically and enviromentally suitable bricks. For found this proportion, the research consisted of (1) making of bricks in full scale, adde up 0%, 5%,10%, 15%, 20%, 25%,30%, 35% e 40% sludge, with size 220x105x45 mm, hand-molded by rammer and baked by industrial kiln; and (2) tecnical and enviromental evaluation of this bricks, according to Brazilian norms. The raw material uses were two distinct clays come from Goianinha/RN and sewage comes from a septic system tank and pumped into tank vehicle, of Natal/RN. The technical evaluation allowed to conclude the addiotion of the sludge brings about signifcant lost of mass and the water absorption grew up according to increase of sludge: every sludge-amended clay bricks absorved more water than control group. Thus, the compressive strength was signicantly decreased because the increase of sludge: bricks with 5% sludge added lost 45% of strength achieved at control group; the bricks made with 10 and 20% lost almost 70% of bigger strength. With up to 25% sludge added to the bricks, the streght decreased over 90%. Concerning heavy metal leaching, the two maximum proportion wich have tecnical approval, it means bricks sludge added with 15 and 20%, can say there is no risk of enviromental contamination using those bricks. This way, in this work context, it can to conclude the maximum proportion atends the technical and enviromental criterion is 20%

Um olho torto na literatura de Graciliano Ramos

This dissertation analyses, within a psychoanalytical e literary perspective, the enigma of blindness in Graciliano Ramos s work. The approach takes into account, mainly, the narratives of Histórias de Alexandre (Alexandre s tales) and Infância (Childhood memories) as both books speak of the same theme: the injured eye. The writer s work is scourged so that a broaden symbolism regarding the hurt eye can be found. The subject is discussed from three significant elements: fragmentation, helplessness and melancholy; all these form the creative aesthetic of Graciliano, merging into a single object. Fragmentation representing the internal shattered world of his characters, which is reflected in the environment; helplessness, directly related to feelings of rejection; and melancholy, characterized by a strong feeling of emptiness. The theme of isolation and loss is discussed based on Mourning and melancholy, by Freud, and other theorizers. There is also a brief dialogue with the Romantic and philosophical theories, which tries to explain the melancholic condition in the individual before moments of distress. Such theories are the support for the understanding of the helplessness of the hero in Graciliano Ramos´s literature and for the assumption that the blindness in the mistreated boy of the book Infância could be the language of the traumatic aspect that colors the entire text of the writer. As matter of fact, it constitutes in the lost object represented in the anguish of the author s characters

Das margens do espelho: um estudo dos reflexos da morte em primeiras estórias, de João Guimarães Rosa

This paper is divided into three chapters, which are structured as follows: in the first chapter, we examine the figure of death and its characteristics in the context of the work of Guimarães Rosa, within a specific type, determining how this figure comes through " imposition "," no "," memory "and" ritual. " We intend to cover all the possibilities that this aspect denotes. In the second chapter, we found the incidence of the mirror as an analysis of our study, characterizing it as a stylistic condition can become a reading key, necessary for interpretation of the book "First Stories". The characterization of the mirror as an element of analysis has a theoretical foundation which stretches out along other literary works that are based on the same object. By setting the points where these works approach the theories of speculation, we want to justify their use from our perspective

A construção de modelos situacionais no padrão discursivo narrativa em quadrinhos

The object of this study is the construction of situation models in the discourse pattern comic book narrative, and sits in the field of Cognitive Linguistics. Its main foundations are the notions of embodied mind (LAKOFF; JOHNSON, 1999), mental simulation (BARSALOU, 1999), discourse pattern (DUQUE; COSTA, 2012) and situation models (ZWAAN, 1999). I stem from the hypothesis that the process of meaning construction in narratives is attached to the simulation of space, of time and of the characters goals and actions within the story world, dimensions which make up the situation models elaborated by the reader. The simulation of these experiences during discourse processing originates from the fact of it having an embodied and cultural basis, i.e., upon being confronted with the clues found in the narrative, the cognitive structures that make up the reader s personal and social memories are triggered and make it possible to activate information which in turn refer to his/her physical and social experiences, built up in the environment in which he/she lives. As regards comic book narratives, the construction of situation models is closely related to the recurring activation of certain cognitive structures originating from graphic resources that are typical of that discourse pattern. These conclusions were drawn from the data analysis taken from the work Palestina (SACCO, 2003; 2004; 2011)

Forró eletrônico: uma análise sobre a representação da figura feminina

Understanding music as a social manifestation, able to represent the time and culture along with their uses and mores, we look at the female figure in the electronic forró genre. Through a reading of the two genres musical and feminine we seek to identify the discourses present in the compositions, which refer to the feminine with thematic and/or terms referring to women. The study focuses on the compositions between 2009 to 2010 which became hits, ie.: those which have attained the highest number of listeners to 96 FM in a program named Paradão 96, broadcasted daily in the city of Natal/RN. Grounded in such concepts as cultural industry, mass culture, folkcommunication and gender, we analyze the processes of meaning production as a result of using the female figure and more accurately, about the representation of women through the discourse of this specific genre. We have chose the descriptive research with a qualitative approach and Discourse Analysis as a technique to identify the terms that refer to women, reflecting on what would be the possible meanings found in these speeches. We point out that in our investigation the female figure turned into a sexual object, erotic and submissive, in their turn, attributes usually given to women, was not a predominant result in the speech of electronic forró gender. With a variant thematic some playful and others about the betrayal of women we have identified that, to the surprise of many, including ourselves, romantic love was the one who led the audience requests during our time frame and that the female figure has several facets within the studied genre

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

A mídia dos outros somos nós: a experiência audiovisual do Ponto de Cultura Cinema para Todos

This research aims to identify the process of appropriation of audio visual (in digital video) for collective symbolic production (participatory video practice that expresses popular culture) in a socio-cultural context where the minorities are. Therefore, we based this study on the students‟ experience of the film and video workshops held by Cinema para Todos (Culture Point Cine for All), in Natal, RN. Culture Point is the basis of the project Programa Nacional de Cultura, Educação e Cidadania Cultura Viva (National Program of Culture, Education and Citizenship - Living Culture) of the Brazilian Ministry of Culture. In 2010, the Cine for All developed three film and video workshops in the state of Rio Grande do Norte (Northeastern of Brazil), in the municipalities of Açu, Lajes and São Gonçalo do Amarante, within a public policy project of socio-cultural inclusion. These three workshops are the focus of this empirical investigation. To support the analysis of this research we consider that the spaces of workshops are sites of the social practices origin, assuming they show the development of the changes of actions that generate new practices. In this socio-cultural context the students as interlocutors process the communicative culture mediation, where come from the logics of action (using digital video) to become a mediatic practice (video auto ethnographic). With the overall goal set and the field of investigative action delimited we considered the methodology of case study suitable for the observation of the object, because it is a phenomenon of modernity, occurring in a context of real life and with little or no control over events. Participant observation and interviews was also applied to this case study. The analytical theoretical support comes from the notion of mediation by Jesús Martín-Barbero and the concept of habitus by Pierre Bourdieu. The research found that a new way of communicating has been developing by this social group, and this reflects the technological change experienced by them. The auto ethnographic videos, short movies, reveal an allegorical trial of the mainstream media, because while they use the mainstream format, they rework the aesthetic, but without revising the history, in fact they proposing to retell the history of themselves full of colorful details and with richness of their forgotten popular culture.

O enigmático problema das gigantes ricas em Lítio e as perspectivas com o satélite Kepler

Lithium (Li) is a chemical element with atomic number 3 and it is among the lightest known elements in the universe. In general, the Lithium is found in the nature under the form of two stable isotopes, the 6Li and 7Li. This last one is the most dominant and responds for about 93% of the Li found in the Universe. Due to its fragileness this element is largely used in the astrophysics, especially in what refers to the understanding of the physical process that has occurred since the Big Bang going through the evolution of the galaxies and stars. In the primordial nucleosynthesis in the Big Bang moment (BBN), the theoretical calculation forecasts a Li production along with all the light elements such as Deuterium and Beryllium. To the Li the BNB theory reviews a primordial abundance of Log log ǫ(Li) =2.72 dex in a logarithmic scale related to the H. The abundance of Li found on the poor metal stars, or pop II stars type, is called as being the abundance of Li primordial and is the measure as being log ǫ(Li) =2.27 dex. In the ISM (Interstellar medium), that reflects the current value, the abundance of Lithium is log ǫ(Li) = 3.2 dex. This value has great importance for our comprehension on the chemical evolution of the galaxy. The process responsible for the increasing of the primordial value present in the Li is not clearly understood until nowadays. In fact there is a real contribution of Li from the giant stars of little mass and this contribution needs to be well streamed if we want to understand our galaxy. The main objection in this logical sequence is the appearing of some giant stars with little mass of G and K spectral types which atmosphere is highly enriched with Li. Such elevated values are exactly the opposite of what could happen with the typical abundance of giant low mass stars, where convective envelops pass through a mass deepening in which all the Li should be diluted and present abundances around log ǫ(Li) ∼1.4 dex following the model of stellar evolution. In the Literature three suggestions are found that try to reconcile the values of the abundance of Li theoretical and observed in these rich in Li giants, but any of them bring conclusive answers. In the present work, we propose a qualitative study of the evolutionary state of the rich in Li stars in the literature along with the recent discovery of the first star rich in Li observed by the Kepler Satellite. The main objective of this work is to promote a solid discussion about the evolutionary state based on the characteristic obtained from the seismic analysis of the object observed by Kepler. We used evolutionary traces and simulation done with the population synthesis code TRILEGAL intending to evaluate as precisely as possible the evolutionary state of the internal structure of these groups of stars. The results indicate a very short characteristic time when compared to the evolutionary scale related to the enrichment of these stars

Avaliação em saúde bucal na perspectiva do usuário: enfoque ao estudo da acessibilidade organizacional

Due to the fact of oral health sector reestructuration within Brazilian public health politics, this work had the object of evaluating, under users point of view, the accessibility to oral health services in Santa Cruz (RN), focusing on the organizational aspect. To achieve this, questionnaires were given to users in their homes, considering the censitary sector. Nine sectors of the urban zone were evaluated, selected by chance, and one from the rural zone, selected by convenience. The sample was composed by 194 users, calculated considering the estimated prevalence of event represented by the indicator I ve never been to the dentist + I ve been to the dentist more than three years ago from the Projeto SB Brasil Report . To complement the results, interviews were made with others actors involved in the process of oral health care: professionals (dentists) and manager (Health Municipal Secretary). From the data obtained it was possible to identify that 12,9% of the population had never visited the dentist, and that the search for the service was not influenced by the users individual and socioeconomics characteristics, excepting the gender. It was verified that 36,1% of the users went to the dentist in less than one year, with the youngests (p<0,05) being among those who went to the dentist more frequently. 63,3% of the interviewed related that they found some kind of difficulty when they search for dentistry services, with the difficulties for schedule, the queues and the long wait among the most cited. It was identified that 43,2% of the users wait three weeks or more for the appointment. It is still pointed out that 71,4% of the interviewed find difficulties to get urgency appointment, the long wait to be attended by the dentist was the most found. 92,9% and 94,1% of the interviewed had never been headed to especialized appointments and complementary exams, respectively. Due to the data founded, it was possible to verify that the accessibility to oral health services in Santa Cruz (RN) is damaged by factors related to the organization of public polices developed, mainly in relation to the working process

Alterações do ciclo sono-vigília moduladas por Dopamina e suas consequências Mnemônicas

Neuroscience is on a rise of discoveries. Its wide interdisciplinary approach facilitates a more complex understanding of the brain, covering various areas in depth. However, many phenomena that fascinate human kind are far from being fully elucidated, such as the formation of memories and sleep. In this study we investigated the role of the dopaminergic system in the process of memory consolidation and modulation of the phases of sleep-wake cycle. We used two groups of animals: wildtype mice and hiperdopaminergic mice, heterozygous for the gene encoding the dopamine transporter protein. We observed in wild-type mice that the partial blockade of the D2 dopamine receptor by the drug haloperidol caused deficits in memory consolidation for object recognition, as well as a significant reduction in the duration of rapid eye movement sleep (REM). We also found a mnemonic deficit without pharmacological intervention in hiperdopaminergic animals; this deficit was reversed with haloperidol. The results suggest that dopamine plays a key role in memory consolidation for object recognition. The data also support a functional relationship between the dopaminergic system and the modulation of REM sleep

Não há você sem mim: histórias de mulheres sobreviventes de uma tentativa de homicídio

The murder-suicide (H / S) has been defined as a shocking crime in which a person takes the life of another and then kills himself within 24 hours. Set up as a gender violence, because men are in majority, the killers and the women victims. This study aims to understand the meanings of the experience of a H / S, from women who have survived this act. This study sets up as a hermeneutic phenomenological research, based on Heidegger`s ontology. We interviewed three survivors of H / S, whose narratives allowed to approach the senses present in their lives. The interviews were transcribed and interpreted in accordance with the hermeneutic circle, as proposed by Martin Heidegger. From the interviews of research participants perceive that these women have built their senses in stocks, represented the family foundation and the presence of a husband and children. This project that moved their lives toward the construction of modes-of-being. We noticed the presence of historicity constructing meanings for the existence of these women. We found reports of an experience of loving relationships characterized by strong jealousy, with the presence of fantasies of betrayal, and marked by a careful affective relationship that put them in the position of object possession of his companions. Reflect that such caring restricted their existence being-for-husband. So the senses that moved their stocks, which aimed his ways existential, was the creation of a family, a reference to their lives, to live a love, and care for the children. Therefore, beyond the already known aspects in studies on violence against women, which made these women continue to choose this relationship was the sense that they had for their existence. It is hoped that this study will contribute to the construction of a new look on violence against women, taking as a basis the Heideggerian hermeneutic phenomenology

A infância no âmbito do discurso dos parâmetros curriculares nacionais

The educational institution, committed to the production and transmission of knowledge, has increasingly revealed a specific dimension of that commitment, which is to form people und to produce certain kinds of subjectivity. The child is involved in a context of subjectivity production becoming the object of expectations; expectations arising from the demands of a globalized world, and based upon a discourse of specialized fields of scientific knowledge relative to childhood. The purpose of the present work is to analyse the discourse found in the Parâmetros Curriculares Nacionais - PCNs (National Curriculum Guidelines) as concerns the first four years of Elementary education, trying to disclose its ideas and conceptions about the subject-child. Conceiving this discourse as an ideological phenomenon in which the word becomes the central stage where contradictory values are confronted, according to Bakhtin thinking, the analysis constitutes an effort to point out the voices which supply its basis, in what it reveals about the child. Assertions such as "preparing children for the working market", or for "exercising their citizenship", among others which can be found in the institutionalized pedagogical discourse, are stated in a universalized and normative sense, and have become the object of doubt and criticism. The investigation on the implicit and explicit conceptions about childhood as revealed in the PCNs, whose spokesperson has been the school, serves as the starting point for a series of other studies and reflections intended to pave the way for the implementation of educational processes which allow for singular manifestations of the subject-child

Silenciosas e silenciadas: descortinando as violências contra a mulher no cotidiano da prostituição em Natal-RN

The prostitution is known as the world's oldest "profession", according to some historians, "the contemporary civilization itself." However, to refer it that way, we can systematically emptying it of expressions of violence that permeate. Furthermore, this statement tries to legitimize prostitution as a practical historically related to the natural condition of women. The main objective of the research is to examine how the activity prostitucional potentiates in different forms of violence in everyday development of prostitution in the city of Natal. Accordingly, the spot of the categories of gender relations and patriarchal violence against women, refute the thesis advocated by much of feminist studies on of prostitution as an expression of autonomy of women and overcoming the patriarchal order of gender. Procedures as set methodological quali-quantitative approach, guided by the method historicalmaterialist dialectic that allows us to apprehend the object of study beyond their immediate, unmasking its contradictions. We conducted nine interviews with prostitutes belonging to the classes of People who develop the activities in the streets and prostitutes Natals` cabarets. We hand with the systematic observation activities promoted by the Association of Prostitutes in Rio Grande do Norte ASPRORN, as the visits to cabarets, as well as participation in seminars held by this entity, at which establish contacts with informants-c which have facilitated access to interviewed. We note that the economic dimension is the factor determinant for their inclusion in prostitution, all to recognize as who found an alternative for survival, since most do not has no professional training and education. Another issue important to be emphasized concerns the areas where unhealthy develop programs which by itself is characterized as a denial of rights, expressed in the socioeconomic inequality that are subject. As the expressions of violence in their daily lives, the main forms identified were the physical and social, however, there is a trend in naturalizes them, the secondary-over other issues identified as most pressing, such as not service payment by the customers. The determinants of violence identified by respondents were assigned to the woman, or is its boldness. We also, the omission of the State in the issue of prostitution, mainly embodied in absence of public policies directed to sexual rights and reproductive and generation of employment and income. Regarding the regulation of prostitution, the majority of the interviewees is contrary, arguing that exacerbate the stigma in this practice

Controle democrático no capitalismo contemporâneo: limites e contradições

This study examines the determinations of the structural crisis of capital in the democratic control effected on the councils of rights and policies. Therefore the research aimed to apprehend and analyze the conjunctural and structural determinations and cyclical changes that incide on democratic control established by the Federal Constitution of 1988. The specific objectives turned to: (1) identify and analyze the theoretical and political fundamentals of democratic control in the production of social service in ENPESS 2010, in the productions of CFESS and the journal social services and society, (2) apprehend and analyze the possibilities, limits, contradictions and social direction of democratic control in contemporaneity and (3) identify and analyze the major political forces that constitute support and opposition to the exercise of democratic control. To approximate to the intended objectives the way theoretical and methodological covered was based in a perspective of totality that allows the apprehension of the object of study in their contradictory dimensions of universality, particularity and singularity. The results enabled to develop critical analysis of theoretical production of the Brazilian social service on the subject, having as snip studies of the journals social service and society; works of ENPESS 2010 and CFESS positioning. It was found, so in analysis undertaken, the spaces of democratic control suffer inflections of capital that shape their practices and social direction. In theoretical productions chosen, identified the prevalence of democratic control studied under an endogenous perspective to participatory canals, with incipient connections to the structural/conjunctural determinations of a historical period of crisis and seeks to restore the hegemony of capital. The positioning of the CFESS tends to recognition of democratic control in its contradictory dynamics recognizing the limits imposed by the sociability of the capital at the present time

Fatores que afetam o apoio de residentes ao desenvolvimento do turismo em sítios arqueológicos: um estudo no Seridó Potiguar

The tourist activity , which appropriates spaces and natural , cultural , social and economic scenarios in a given locality , requires a model of integrated development necessarily reconciling the support of residents. In this perspective , this study aims to analyze the factors influencing the support of residents in tourism development in archaeological sites , specifically in the two counties of Parelhas and Carnaúba dos Dantas , in Rio Grande do Norte, in the region of Seridó Potiguar as well as the interrelationship existing between these factors . To achieve the proposed objective of the research , a descriptive -exploratory and quantitative study based on the study of Nunkoo and Hamkisson (2012 ) , using the technique of Structural Equation Modeling - SEM to explain the relationships of the constructs used in this research. Data collection was performed during the periodof May 2013 to July 2013. Among other studies, results indicate that , for the profile of the interviewees used , the higher the confidence of the community residing in the government agencies responsible for, the largest tourism will support the resident to the tourism development and that this supply relationship institutions and government agencies an opportunity to enhance their development strategies and social thinking of the resident agent of tourism . It was also found that the analysis model proposed has a better structural relationship when used interviewees who have knowledge about the activities in the archaeological sites , then suggesting the need for further research on the effect of the level of knowledge of the interviewee on the object and support of residents to tourism development
