Um olhar sobre o cotidiano e as re-definições espaciais no Bairro Potengi, Natal/RN

This work aims to conduct an analysis on the production of space and the dynamics between social agents that act and interact, albeit in different ways, in the production and re-production space in the Neighborhood Potengi in Natal, Rio Grande do Norte. The neighborhood is undergoing a process of dynamism undeniable and has a daily marked by heterogeneity, especially as a neighborhood in transition. So your analysis, from the perspective of the dialectical method, contributes to the understanding of the production space can be analyzed through the study of the forms and content, and may contribute to its real apprehension. After all, the city reflects forms, assumes functions, features and content that dynamic influences and is influenced by human relationships. Thus, this research seeks to analyze the production of space, based on the observation and study of the rich daily life of different social agents that operate within concrete quoted

Vende-se uma vila: análise intra-urbana das vilas na Vila de Ponta Negra e no bairro de Nova Descoberta - Zona Sul de Natal

This dissertation is about low-income rental housing vilas in the South Zone in the city of Natal. Vilas are a string of houses, built privately in an urban plot of land, usually a backyard, facing a narrow street beco. This type of housing is originated in the 19th century in the Brazilian scenario. In Natal, this has become more popular since the late 1960s. This study is aimed at analyzing the urban integration of the vilas, considering that these house a low income population, vis à vis the speedy development of Natal s most economically dynamic area. The study starts with a discussion of the production of space, taking into consideration categories such as use value, exchange value, commodity and land rent. Field work was undertaken through structured interviews with dwellers of vilas in Nova Descoberta and Ponta Negra neighbourhoods. Owners of vilas were also interviewed. Data collected indicated worrisome housing conditions. Vilas, in the areas researched, are increasingly becoming unwelcome, constituting guetos in a place where landscape is changing rapidly. Gentrification is fast under way, first because of rise in rent and taxes; second because of general rise in living costs

Experiências subjetivadoras no limite da pele: Uma análise de práticas discursivas inscritas em tatuagens

This research aims to study the constitution of subjectivities in discursive practices included in imagistic and verbal texts of tattoos. Seeks to grasp the effects of meanings which translate emotions, experiences and disaffection that marked and / or transformed the lives of tattooed subjects. This thesis was anchored in Foucault's theories (1990, 2010, 2012) that address ways of subjectivity from the writing itself, transgression technologies as overshoot, opening new possibilities for discursive subject producing care of itself. Still notions from this analysis of French discourse (AD), as interdiscourse and discursive memory are used. The nature of qualitative research intends to contribute to the understanding of discourse as social practice constitutive of meaning in ways of being of the subject, as well as production of discourses about social norms. The corpus is composed of testimonials and imagistic and verbal texts of five subjects, among the ten respondents who tattooed experiences in the skin. The results show data demonstrating the constitution itself through lived experiences and printed on the skin. The meanings generated in the skin are types of subjectivities that reflect happiness, resilience, protection and immortality. We conclude that our subjects are positioned discursively in order to rebuild their bodies and experiences as necessary and that the images and statements recorded in bodies produce effects felt around the reflection about the ways of life and the existence choices of each one of the tattooed subjects.

O ciclo indiano de Marguerite Duras à luz da comparação diferencial: a reconfiguração de um personagem

La présente recherche a pour objectif analyser la reconfiguration d'un personnage dans deux romans et dans un texte dramatique de l’écrivaine française Marguerite Duras, qui font partie du Cicle indien. Ils sont : Le Ravissement de Lol V. Stein (1964), Le vice-consul (1965) e India Song (1975). Adoptant la perspective de la Comparaison Différentielle comme approche littéraire, proposée par Ute Heidmann (2008, 2010, 2012), professeur-docteur de l'Université de Lausanne (Suisse), ce travail cherche étudier le personnage Anne-Marie Stretter présent dans ces trois œuvres. On cherche comprendre de quelle manière se produit la réécriture du personnage à partir de trois axes d'analyse : les modalités de l'énonciation, en considérant l'analyse et la comparaison de l'œuvre littéraire comme un événement énonciatif, partant du concept de la scène d'énonciation, proposé par Dominique Maingueneau (2010) ; les modalités d'inscription générique, étroitement liées aux modalités énonciatives, avec un fondement théorique en Todorov (1980) et Heidmann (2012) ; et les modalités de dialogisme intertextuel et interdiscursif, considérant dans la relation dialogique des nouveaux et différentes propositions de sens. Para la compréhension de cela nous partons de Bakhtine (2010), Kristeva (1974), Todorov (1981) et de l'idée de dialogisme et intertextualité, pour arriver à l'idée d'interdiscours proposée par Heidmann (2010, 2012). À partir de cette étude, nous pouvons observer dans l'œuvre d'un même auteur différentes manières de construction d'un personnage, chacun avec ses spécificités et complexités, variant dans le genre et espaces discursifs. L'intérêt de la comparaison différentielle dans cette étude, partant d'un trait commun entre les trois œuvres, est de rendre visible les différences épistémologiques et les nouvelles propositions de sens.

Tratamento de cascalho de perfuração utilizando sistemas microemulsionados

The oil industry is one of the activities that generates more waste to the environment. The drill cuttings is a waste generated in large quantities in the drilling process and that may cause environmental damage such as soil contamination and consequently the contamination of groundwater if disposed of without prior treatment. Arises the need to develop scientific activities and research ways to adapt these wastes the current environmental standards. In the case of solid wastes, the NBR 10004: 2004 of the Brazilian Association of Technical Standards (ABNT) classifies them into class I waste (hazardous) and class II (not dangerous), which determines which wastes may or may not be discarded in the environment without causing environmental impact. This study presents a novel alternative for treating drill cuttings, where this waste was classified as class I (Abreu & Souza, 2005), mainly by removing the n-paraffin present in it, since this arises when using drilling fluids base oil. Using microemulsion systems promotes the removal of this contaminant drill cuttings samples from wells located in Alto do Rodrigues - RN. Initially, we determined the concentration of paraffin using infrared method in samples were extracted with ultrasound, we obtained a paraffin concentration in the range from 36.59 to 43.52 g of paraffin per kilogram of cuttings. Used two microemulsion systems containing two nonionic surfactants from different classes, one is an alcohol ethoxylated (UNTL-90) and the other an nonylphenol ethoxylated (RNX 110). The results indicated that the system UNTL-90 surfactant has better efficiency than the system with RNX 110. The study of the influence of contact time at the extraction showed that for times greater than 25 minutes has a tendency to increase the percentage extraction with increasing contact time. It was also observed that the extraction is fast because at 1 minute contact has 22.7% extraction. The reuse of the microemulsion system without removing the paraffin extracted in previous steps, showed reduction of 29.32 in percentage of extraction by comparing the first and third extraction, but by comparing the first and second extractions reduction is 8.5 in percentage extraction, so the systems reuse optimization can be an option for economically viable removing paraffin from cuttings. The extraction with shaking is more effective in the treatment of cuttings, reaching the extraction percentage of 87.04%, that is, obtaining a drill cuttings with 0.551% paraffin. Using the percentage of paraffin employed in non-aqueous drilling fluids and fluid maximum limit on cuttings for disposal established by the Environmental Protection Agency of the United States (US EPA), one arrives at the conclusion that the level of paraffin on gravel cannot exceed 3.93%. Conclude that the amount of paraffin in the treated cuttings with the microemulsion system with shaking is below the established by US EPA, showing that the system used was efficient in removing the paraffin from the drill cuttings.

Vestimentas em performance: composições em modos do corpo

This research deals with the possible relationships between the body and the garment in performative scenic states across the contemporary scene, the philosophy of fashion and the philosophical arguments of profanity and dispositive. Some works were observed and cited in this dissertation, for this I conducted structured interviews with eight artists of performance, as a methodological strategy that could bring data about the experiences of this dresses and/or naked bodies on the scene, in addition to literature and revealing the action of clothing on the body as well as its influence on the subjectivities of that whom performes and the public. These relationships can be experienced in the process of creating costumes in contemporary scene naming the possibility of modes of the body, as ways that emerge and constitute as creative, discursive and aesthetic alternatives.

Técnicas estendidas para saxofone em obras compostas por meio de colaboração compositor-intérprete

This dissertation deals with the use of extended techniques for the saxophone in the piece Minus (for solo saxophone in Bb), composed through a composer-performer collaboration between Agamenon de Morais and the saxophonist Kleber Dessoles. The text is organized in the following manner: the first part brings the historical background of the concert music written for the saxophone since the beginning of the 20th-century, exploring the use of extended tehcniques and the main characters and historical facts of this period, with data obtained through a literature review; the second part deals with the issue of the composer-performer collaboration, since cases documented in the 18th and 19th centuries until nowadays, exploring in which different ways collaborations may happen and the motivations behind them; the third and final part is about the specific work, followed by a detailed description of the collaboration between the composer and the interpreter, as well as detailed explanations about the extended techniques present in the work (multiphonics and flatterzunge), through bibliographic and documental research, as well as descriptions of the meetings between composer and interpreter. At the end of the collaborative process, one may say that the final result was created from a sum of the composer's knowledge with the interpreter's, almost as if the composition had double authorship. The document describing this process may help composers and interpreters in composing for the saxophone, as well as guide future collaborative experiences.

Aprendizagem musical na Orquestra Sinfônica da UFRN

Music and music education are present in the daily lives of people in different ways and in multiple contexts. In this study, we highlight the musical training in the orchestral context aiming to understand how learning music happens in the Symphony Orches tra of the Universidade Federal do Ri o Grande do Norte – OSUFRN. To achieve this goal, we identified all the activities, structure and functioning in OSUFRN; we have observed the development of activities of the group by checking the interactions among the participants of the orchestra and the different ways to learn music in that orchestral context. The research is based on discussions about collective musical practice, instrumen tal training in music education, the process of learning and the relationship between young people and music in the context of collective musical practice learning. Qualitative approach and case study were used as methodological procedures. Data collection was established by means of on - site observations, accompanying of the activities, rehearsals and performances of group and semi - structured interviews with the conductor and some participants with more time in the orchestra. We have also used photographs a nd footage that helped us in the procedure collection and construction of data. The analysis and interpretation of these data were enforced by Content Analysis featuring. It reveals the musical learning, through learning instances perceived in rehearsals, concerts, in living with the conductor and between musicians, teachers, employees and guest musicians, individually in travel and exchanges with other orchestral groups. In this way the activities developed by the group enable a comprehensive musical educa tion that guides to acquire autonomy in their learning and preparing them for future careers.

Conhecimentos alternativos e ecologia dos saberes: o difícil diálogo do sistema de saúde oficial

Le present travail a pour objectif, discuter le dialogue entre deux des formes de penser le processos santé-maladie: la médécine traditionnelle et celle scientifique. Et cette dernière représentée par le Système Unique de Santé, particulièrement par une Équipe de Santé de la Famille. Partant du questionnement “quel est le rôle de chaque système de santé dans les problèmes sanitaires ainsi que dans la prévention des maladies?”, il s‟agit de vérifier si l‟ ”Écologie des Savoirs” discutée par Santos (2007) a été appliquée dans les deux manières de penser et pratiquer les politiques de santé; tenant em compte que chacune d‟elles ayant son champ de possibilites et d‟impossibilités agit directement sur le quotidien des aires géographiques concernés par la recherche: le District de São João do Abade dans le Municipe de Curuçá/PA et l‟Équipe de Santé de la Famille Abade localisée dans ce même district. Cette étude fut réalisée à partir d‟instruments de collecte de données comme la recherche de terrain, l‟observation directe et les interviews semi-structurés (HAGUETTE, 1997) e apports théoriques à partir de certains des concepts clés les plus utilisés par les Épistémologies du Sud où nous mettons en relief l' “Écologie des Savoirs” (Santos, 2007); le “travail de Traduction” (SANTOS, 2008); la “Sociologie des Absences et la Sociologie des Émergences” (SANTOS, 2004); le concept de “Santé-Maladie” (MINAYO, 1988); ainsi que les discussions autor des “Savoirs de la Tradition” (ALMEIDA, 2010; RAMALHO et ALMEIDA, 2011). La stratégie “Santé de la Famille fut pensée à travers la vision de Guedelha (2008) et Vilar et al. (2011) où à partir de cette dernière la discussion sur le concept de “Médécine Communautaire” (DONNANGELO e PEREIRA, 1976) comme recours importante dans la recherche de l‟ “Écologie des Savoirs” dans la Stratégie Santé de la Famille a été possible.

Efeito da adição de WC e Co na sinterização e propriedades mecânicas da alumina

Composites based on alumina (Al2O3), tungsten carbide (WC) and cobalt (Co) exhibit specific properties such as low density, high oxidation resistance, high melting point and high chemical inertia. That composite shows to be a promising material for application in various fields of engineering. In this work, the mechanical properties of the composite (Al2O3 – WC – Co), particularly density and hardness, were evaluated according to the effects of the variables of powder processing parameters, green compact and sintered. Powder composites with the composition of 80 wt% Al2O3, 18 wt% WC and 2 wt% Co were processed by high energy ball milling in a planetary mill for 50 hours as well as mixed by manual mixing in a glass vessel with the same proportion. Samples were collected (2, 10, 20, 30, 40 and 50 hours) during the milling process. Then, the powders were compacted in a cylindrical die with 5 mm in diameter in a uniaxial press with pressures of 200 and 400 MPa. The sintering was in two stages: first, the solid phase sintering was performed at 1126 and 1300 °C for 1 hour with a heating rate of 10 °C/min in a resistive furnace under argon atmosphere for green samples compacted in 200 and 400 MPa; the second sintering was performed on dilatometer in solid phase at 1300 °C for green sample compacted in 200 MPa, another sintering also was performed on dilatometer, this time in liquid phase at 1550 °C for green samples compacted in 200 and 400 MPa, with the same parameters used in resistive furnace. The raw materials were characterized by X – ray diffraction (XRD), X – ray fluorescence (XRF), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and laser particlemeter. The sintered samples were subjected to microhardness testing. The results showed that high energy milling achieved to the objectives regarding the particle size and the dispersion of composite phases. However, the hardness did not achieve to significant results, this is an indication that the composite has low fracture toughness.
