A produção do mobiliário urbano nos espaços públicos :o desenho do mobiliário urbano nos projetos de reordenamento das orlas do Rio Grande do Norte

This work aims to analyze and evaluate the Urban furniture designed to public areas according to the Revitalization planning for Rio Grande do Norte coastland, defining visual relations among urban elements in the landscape of revitalized public urban areas with cultural, paisagistic and touristic values and the design process used for developing urban furniture to those areas, observing the incoming consequences use to that process in a specific urban context which alters use, functions, cultural images as well as social values attributed to each particular place. Environmental perceptions, legibility of local cultural references and their representation through the design of urban elements, act in a positive or negative manner over the inhabitants cognition process of some particular revitalized area, determining new use and attributions to those areas. Designs for coastal urban interventions try excessively to standardize technical media, construction materials and planning configurations, creating artificial sceneries that segregates users, imposing new structures and usage, generating, consequently, the so called non-places and burlesque regionalism. The research is divided into 4 chapters: 1) Theoretical support (Industrial design; Urban furniture; Public urban spaces; Urban image and environmental perception; Urban occupation and interventions in coastland areas); 2) Methodological procedures and data collection; 3) Analysis of Rio Grande do Norte coastal areas and their urban interventions; 4) Final considerations and Industrial Design contributions to the subject

Otimização do processo de síntese do aluminato de cobalto via método de polimerização de complexos (MPC) através do planejamento fatorial fracionado

In the ceramics industry are becoming more predominantly inorganic nature pigments. Studies in this area allow you to develop pigments with more advanced properties and qualities to be used in the industrial context. Studies on synthesis and characterization of cobalt aluminate has been widely researched, cobalt aluminate behavior at different temperatures of calcinations, highlighting especially the temperatures of 700, 800 and 900° C that served as a basis in the development of this study, using the method of polymerization of complex (CPM), economic, and this method applied in ceramic pigment synthesis. The procedure was developed from a fractional factorial design 2 (5-2) in order to optimize the process of realization of the cobalt aluminate (CoAl2O4), having as response surfaces the batch analysis data of Uv-vis spectroscopy conducted from the statistic software 7.0, for this were chosen five factors as input variables: citric acid (stoichiometric manner), puff or pyrolysis time (h), temperature (° C), and calcinations (° C/min), at levels determined for this study. By applying statistics in the process of obtaining the CoAl2O4 is possible the study of these factors and which may have greater influence in getting the synthesis. The pigments characterized TG/DSC analyses, and x-ray diffraction (XRD) and scanning electron microscope (SEM/EDS) in order to establish the structural and morphological aspects of pigment CoAl2O4, among the factors studied it were found to statically with increasing calcinations temperature 700°< 800 <900 °C, the bands of Uv-vis decrease with increasing intensity of absorbance and that with increasing time of puff or pyrolysis (h) there is an increase in bands of Uv-vis proportionally, the generated model set for the conditions proposed in this study because the coefficient of determination can explain about 99.9% of the variance (R²), response surfaces generated were satisfactory, so it s possible applicability in the ceramics industry of pigments

The results of X-ray diffraction confirmed the formation of the tetragonal and cubic phases in accordance with the content of dopants. The photoluminescence spectra show emission in the region corresponding simultaneous to blue (450 nm), green (550 nm) and red (615 nm). According to the results, ZrO2 particles co-doped with rare earth ions is a promising material white emission with a potential application in the field of photoluminescence

Análise de Sustentabilidade em Projetos de Instalações de Produção de Petróleo

A proposal for a global analysis of sustainability in projects related in oil facilities is presented. By considering economic, environmental and social aspects in the early stages of design, the suggested method is more comprehensive and can be used to complement the analysis commonly applied in the petroleum industry, such as: Study of Technical and Economic Feasibility; Environmental Impact Assessment and Risk Analysis. Several authors, associations, certification bodies and oil companies suggest different approaches to study sustainability in some specific activities (or industries). In this study, a checklist of significant sustainability aspects for the oil industry (surface facilities) was assembled. In addition, a matrix was developed to assess the sustainability items relevant to these projects. In this work, the checklist interacts with the matrix to perform a "Preliminary Analysis of Sustainability of the Enterprise" (APSE). This method allows the identification of aspects that contribute significantly to global sustainability. From this analysis, which includes economic, social and environmental aspects, is built a report that is used to analyze qualitatively and quantitatively the impact of the sustainability aspects of the project. In this analysis are identified items that strongly influence the economic, social or environmental aspects and evaluated alternatives that can increase the overall sustainability of the project. Finally, the alternatives that can be used to indicate the most sustainable option are identified. This method was applied in a project (design) of a small offshore platform. This case study shows how the APSE can contribute to the identification of sustainability initiatives for the enterprise. The results showed that relevant aspects can contribute decisively to global sustainability. Finally, it was observed that the proposed method can contribute to increased rates of sustainability, even after application of analysis commonly used in these projects

Modelagem do desempenho ambiental dos projetos de exploração e produção aplicando equações estruturais

A legislação ambiental e os principais agentes que se relacionam com a empresa se constituem em fatores exógenos que não podem ser negligenciados ao formular-se e avaliar-se a política ambiental corporativa. As influências exógenas e seus efeitos sobre a gestão ambiental e o gerenciamento de projetos de exploração e produção (E&P) e, por essa via, sobre o desempenho ambiental, foram objetos de estudo desta tese. Embora o desempenho ambiental seja um assunto relevante, a pesquisa sobre esse tema ainda é escassa. Tal carência desponta ainda mais acentuada quando se aborda o desempenho ambiental de projetos na indústria de petróleo e gás. O principal objetivo deste estudo foi avaliar a relação entre a legislação ambiental vigente, as ações de órgãos reguladores, fornecedores, empresas terceirizadas e comunidades locais e o desempenho ambiental dos projetos de E&P na indústria de petróleo e gás e, também, analisar os efeitos do sistema de gestão ambiental e o gerenciamento dos projetos sobre tal desempenho. Na fase abdutiva, foi conduzido um estudo de caso com abordagem qualitativa em uma grande empresa brasileira do setor de petróleo e gás, na fase dedutiva, foi realizada uma pesquisa survey explanatória de corte transversal com abordagem quantitativa, incluindo 113 projetos de E&P de cinco unidades executoras da empresa. Foi formulado um modelo conceitual, com cinco construtos e sete hipóteses de pesquisa, representativo dos efeitos de fatores externos sobre o desempenho ambiental dos projetos de E&P. Os dados foram tratados aplicando a Análise Fatorial Exploratória e a Modelagem de Equações Estruturais com aplicação dos softwares IBM® SPSS® Statistics 20.0 e IBM® SPSS® Amos 18.0. O modelo de equações estruturais foi reespecificado e estimado utilizando o método de Máxima Verossimilhança e o procedimento bootstrap com 2000 reamostragens, até alcançar adequados valores dos índices de ajustamento. O modelo mostrou boa aderência às evidências empíricas, representando uma teoria explicativa dos fatores que influenciam o desempenho ambiental dos projetos de E&P na empresa estudada. As estatísticas descritivas apontaram adequado desempenho dos projetos de E&P com relação aos efluentes descartados, volume de água reutilizada, redução de resíduos e práticas de reciclagem. Identificou-se que projetos de maior porte alcançam melhor desempenho ambiental em relação aos de menor tamanho. Não foram achadas diferenças significativas entre os desempenhos de projetos executados por unidades operacionais distintas. Os resultados da modelagem indicaram que nem a legislação ambiental, nem os agentes externos exercem influência significativa sobre a sistemática da gestão dos projetos de E&P. Os agentes externos atuam sobre a gestão ambiental da empresa exercitando capacidades colaborativas, obstrutivas e propositivas. A legislação ambiental é percebida como entrave ao desenvolvimento dos projetos ao longo de seu ciclo de vida, principalmente, pelas deficiências dos órgãos ambientais. Identificou-se que o sistema de gestão ambiental influencia diretamente o Programa de Desenvolvimento e Execução de Projetos de E&P, que, por sua vez, provoca efeitos diretos e indiretos sobre o desempenho ambiental. Finalmente, comprovou-se que o Sistema de Gestão Ambiental da empresa é determinante para o desempenho ambiental dos projetos de E&P, tanto pelos seus efeitos diretos, como pelos indiretos, estes últimos mediados pela sistemática de gestão dos projetos de E&P

Organizations are seeking new ideas, tools and methods aiming to improve management process and performance. On the other hand, system performance measurement needs to portray organizational changes and provide managers with a set of true and more appropriate information for the decision-making process. This work aims to propose a performance measurement system in the academic field regarding Research, Development and Innovation (RDI) in the oil and gas industry. The research performed a bibliographic review in a descriptive exploratory manner. A field research was conducted with an expert focus group in order to gather new indicators. As for the validation of these indicators, a survey with experienced professional was also realized. The research surveyed four segments in and outside of the Federal University of Rio Grande do Norte-Brazil such as oil and gas project coordinators, staff at Academic Planning Offices, FUNPEC employees as well as coordinators from Petrobrás. The performance measuring system created from this study features three interrelated performance indicators pointed out as: process indicators, outcome indicators and global indicators. The proposal includes performance indicators that seek to establish more appropriate strategies for effective institution management. It might help policy making of university-industry interaction policies

Preparação e carcterização de complexos multicomponentes contendo ciclodextrinas e benznidazol

The benznidazole (BNZ) is the only alternative for Chagas disease treatment in Brazil. This drug has low solubility, which restricts its dissolution rate. Thus, the present work aimed to study the BNZ interactions in binary systems with beta cyclodextrin (β-CD) and hydroxypropyl-beta cyclodextrin (HP-β-CD), in order to increase the apparent aqueous solubility of drug. The influence of seven hydrophilic polymers, triethanolamine (TEA) and 1-methyl-2- pyrrolidone (NMP) in benznidazole apparent aqueous solubility, as well as the formation of inclusion complexes was also investigated. The interactions in solution were predicted and investigated using phase solubility diagram methodology, nuclear magnetic resonance of protons (RMN) and molecular modeling. Complexes were obtained in solid phase by spray drying and physicochemical characterization included the UV-Vis spectrophotometric spectroscopy in the infrared region, scanning electron microscopy, X-ray diffraction and dissolution drug test from the different systems. The increment on apparent aqueous solubility of drug was achieved with a linear type (AL) in presence of both cyclodextrins at different pH values. The hydrophilic polymers and 1-methyl-2-pyrrolidone contributes to the formation of inclusion complexes, while the triethanolamine decreased the complex stability constant (Kc). The log-linear model applied for solubility diagrams revealed that both triethanolamine and 1-methyl-2-pyrrolidone showed an action cosolvent (both solvents) and complexing (1-methyl-2-pyrrolidone). The best results were obtained with complexes involving 1-methyl-2-pyrrolidone and hydroxypropylbeta- cyclodextrin, with an increased of benznidazole solubility in 27.9 and 9.4 times, respectively. The complexes effectiveness was proven by dissolution tests, in which the ternary complexes and physical mixtures involving 1-methyl- 2-pyrrolidone and both cyclodextrins investigated showed better results, showing the potential use as novel pharmaceutical ingredient, that leads to increased benznidazole bioavailability

Juventude rural e projetos de vida: a experiência do consórcio social da juventude rural em São João do Sabugi

The presented research however has as object to apprehend the contribution of the Social Trust of Agricultural Youth in Is João of the Sabugi, in the individual and collective projects of life of the agricultural young. In it interests to know them which are the dreams and desires of these young, its relation with familiar agriculture, its desires of permanence in the field, as well as the relation of the trust with the fortalecimento of its projects of life. Thus, the general objective is to argue the contribution and influence of the Social Trust of Agricultural Youth in Is João of the Sabugi, in the individual and collective projects of life of the young of the city. The construction of the subject on agricultural youth to the contact with the land and the work in familiar agriculture were one strong expression identified in this research, exactly leading in consideration that nor all possess the desire to remain young agricultural , or at least young agriculturists. For the young, agricultural being is express through not only the contact with the agricultural work, but also the process of sociability, formation of affective bows, possibilities of new learnings, valuation of the agricultural way and its potentialities, of that the corporeal property and cultural is possible to be young in the agricultural way with access, historicamente denied

Tecendo os fios de rede: juventude e produção de si em projetos sociais.

The study is about youthful subjectivities in quarters, of the West Zone of Natal-RN, marked for lacks and contingencies that constitute the everyday life of the social existence of its young inhabitants. For this purpose the researchers selected two youth groups: the Association of Youths Constructing Dreams (in the quarter of Felipe Camarão) and Lelo Melodia Crew (Quarter of Guarapes). Both are articulated through the strategy of coalition in regional and national nets. The hypothesis is that inside the groups and nets new youthful citizens arises. That would be a change in the representation of poor youth: from 1980 s street children - young whose social stigma associated poverty and crime to late 1990 s kids of project (pointing their trajectory in social projects) or, in present days, called as young peripherals - for the enrollment in cultural movements, as the hip hop movement - These new young citizens are contributing to new social imagery significations on poor youths. The methodology encloses: a) focal group; b) participant research analyzing the making arts (ways to think, social daily practices, actions engaged in a diversity plans) of youth groups; c) life stories of some of the youngs produced in workshops; d) not structuralized interviews. d) several documents of the groups; e) local and national surveys. Results emphasize a feeling of opening to a project of autonomy in relation to a social system that leaves them in a situation of social precariousness. Conclusion remarks that such practices of the youthful groups through the art, leisure, sport and culture unfold politics effect so that can point innovative forms of politics participation on the part of this specific segment of poor youths of Brasilian country, although conflicts and paradoxes crosses individual citizens, youth groups and youth nets.

Pedagogia de projetos e etnomatemática: caminhos e diálogos na zona rural de Mossoró - RN

Teaching Mathematics in a contextualized and significant manner, in the world of the child and the adolescent, requires a solid theoretical and methodological basis on the part of the researcher. The present work found this foundation in two ways: teaching with projects and ethnomathematics. It is understood that these ways have points in common, such as: the real, interdisciplinarity, teaching methods, flexibility in sequencing the curriculum and interactive learning. This makes possible a theoretical cross-fertilization, which is important for the teaching/learning of Mathematics. Those points are merged in the present proposal, making possible new strategies, distinct from those of the Traditional Teaching Methodology and giving raise to an Alternative Teaching Methodology, which is to be lived in the Mathematics classrooms. This work gives a new direction to teaching, going beyond the traditional forms of education by allowing the teaching of Mathematics to become integrated with other school subjects, resulting in significant learning. In order to implement the proposal, it is necessary to form partnerships with teachers, pupils and the whole community, so that the way can be traced by continual dialogue

Professoras e projetos: concepções e práticas no ensino fundamental

The discussion we have established in this study is about how the practice is developing educational projects based on work with because the methodological choice of the teacher. The study of an ethnographic qualitative approach was conducted with a group of six teachers in two public schools in School Administrative Zone north of the city of Natal / RN. Data were constructed from semi-structured, reinforced by the direct observation of the practice of teaching of teachers. The goals outlined were to identify the reasons why the option for the project, listing the benchmarks that subsidized their construction, the observation of everyday experience in educational planning and development of projects developed. In the light of information we can notice a complex and even contradictory, which is confusing the concepts and practices are weakened. The analysis revealed inconsistencies between theory and practice in working with projects, the fruit of little theoretical development of teachers. The adoption of the project as a methodological option has meant a change in direction of the effective action didactic. Reflects on this situation, it was concluded that there is a need to broaden the understanding of the significance of this type of work, covering the different dimensions that involve the practice of research, research and training of teachers. Even preventing the intentions and initiatives of the teachers, it must be emphasized is the process of learning within an approach that focuses the process of learning in multiple dimensions, inter-relational, both the capabilities of students in the areas of knowledge.

Construindo um modelo de referência ao despertar do interesse dos sujeitos em projetos educativos em ambiente on-line

This dissertation was written for the making of a model to be used as reference to the construction and diagnoses of educational projects in on-line environments. The model approaches a series of characteristics, technical and humans, which if considered can increase the potential of awake the interests to the active use of these projects for the students and build conditions to the development of an active posture by the students, fundamental factor to the educational advances. Focused in the students, not in the technology in use, we propose this model as a guide, reference to be used in a critical way in relation with every educational context. This research was made from the qualitative category, trough the method of study of case, using as reference to the analysis the use of the website guanabara.info - website outside of the school context - by it users, heard through the internet, by the use of semi-opened interview, in a data taken of the primary type. We follow as theoretical references Paulo Freire´s work, considering his vision of education and the building of knowledge as a process which occurs between man, and Celestín Freinet, in his pedagogy of humanized and critical insertion of the technologies in the school. At the end, we show the practical utilization of the model constructed using it for the diagnostics of an educational project in the on-line educational environmental moodle

Por trás de links, sempre existem pessoas: o anonimato como fator de pertencimento no uso de redes sociais on-line em projetos educacionais

The thesis investigated how social networks online that allows anonymous postings can be used by teachers and students to promote the meeting between the sexual education and the needs and expectations of young people face a crosscutting theme, remarkably a taboo. It needs teaching strategies more efficient than those traditionally defended. With this experience, found in a short course about sexuality and health, we sought to go beyond the use of social networks for social entertainment, showing they can be an field that favors the process of teaching and learning. The research was based on the convergence of the communication concepts from Paulo Frere and another from Jürgen Habermas, as well as the philosophical concepts of utopia, ideology and dialectic are interrelated not only among themselves, but also inside an education field. Methodologically in this thesis, we adopted the category of qualitative research; the method is a combination of case study with action research. The technique was the use of questionnaires, data collection was in attendance and the types of data were primary. Finally, we present, then, the idea the communication is not in the middle, but in the trusty relationship established between the interlocutors. In this way, we can think when a student has met their need to be able answer his questions about sex with their teacher through an online social network that allows anonymity and through which the student knows who responds is their teacher, but the teacher can not distinguish the identity of his students, this dialogic relationship serves to get claims of the validity that are characterized as potential communicative action
