Estudo experimental sobre o comportamento do escoamento bifásico água - ar para a medição de vazão em placa de orifício

The measurement of flow through the prediction of differential pressure is widely used in industrial day-to-day, this happens mainly due to the fact that it is used for various types of fluids, such as gas flow and liquid with viscosity distinct even flow of fluids with particles in suspension. The suitability of this equipment for measuring mass flow in two-phase flow is of paramount importance for technological development and reliability of results. When it comes to two-phase flow the relationship between the fluids and their interactions are of paramount importance in predicting the flow. In this paper, we propose the use of concentric orifice plate used in small diameter pipes of 25.4 mm order where a two-phase flow flows between water-air. The measurement of single-phase flow was made with the use of data in NBR 5167-1 which was used to Stolz equation for measuring discharge coefficient. In the two-phase flow was used two correlations widely used in the prognosis of mass flow, the pattern of Zhang (1992) and the model of Chisholm (1967), to the homogeneous flow model. It was observed that the behavior found in Zhang model are consistent more realistic way the mass flow of two-phase flow, since the model Chisholm extrapolate the parameters for the downstream pressure P2, the orifice plate, and the rated discharge coefficient. The use of the change in pressure drop P1-P2 and discharge coefficient, led to a better convergence of the values obtained for the two-phase air-water stream.

Narrativa transmídia e a expansão do universo ficcional: os princípios e as estratégias de transmidiação da telenovela Cheias de Charme

This research analyzes the transmedia narrative television series Cheias de Charme, understood as a fictional multiplatform world, composed of several pieces distributed in different media, and into the context of media convergence. With a view to its expansion in various media controlled by production, we investigated how the principles (Jenkins 2008, 2009a, 2009b) and the strategies of expansion and spread (Fechine et al., 2013) were appropriate for fiction. To do this, literature reviews were conducted about transmidiation processes and the specifics of transmedia narrative, in order to identify possible areas of action and forms of engagement with the public. In addition, he reflected on reconfigurations of the soap opera genre in the era of participatory culture. For a better understanding of the dissertation, the observations were divided into four distinct chapters, taking as a guide and starting point the inclusion of the soap opera in the internet environment. With the aid of a descriptive research with a view to the application of the Case Study procedure in the light of Gil contributions (2010), it is believed that the proposed objectives were achieved. Finally, it was concluded that Cheias de Charme, aired by TV Globo in 2012, in time of 19h, we used creative and planned actions that have worked effectively in developing a transmedia narrative.

Um estudo sobre polinômios matriciais

This research work aims to make a study of the algebraic theory of matrix monic polynomials, as well as the definitions, concepts and properties with respect to block eigenvalues, block eigenvectors and solvents of P(X). We investigte the main relations between the matrix polynomial and the Companion and Vandermonde matrices. We study the construction of matrix polynomials with certain solvents and the extention of the Power Method, to calculate block eigenvalues and solvents of P(X). Through the relationship between the dominant block eigenvalue of the Companion matrix and the dominant solvent of P(X) it is possible to obtain the convergence of the algorithm for the dominant solvent of the matrix polynomial. We illustrate with numerical examples for diferent cases of convergence.

As Bibliotecas Universitárias de Portugal e Nordeste do Brasil: estudo sobre o impacto e mediação das tecnologias digitais

Analisa as práticas de mediação desenvolvidas nas bibliotecas universitárias pelos bibliotecários diante das tecnologias digitais. Para tanto estabelece como objetivo geral analisar de forma comparativa, o impacto e mediação das tecnologias digitais no funcionamento de bibliotecas Universitárias de Portugal e da região Nordeste do Brasil. Integraram esta pesquisa 10 universidades federais brasileiras e 12 universidades públicas portuguesas, com um total geral de 115 bibliotecários, que são os sujeitos participantes. É uma pesquisa qualitativa que adota o método quadripolar – recomendado para os trabalhos desenvolvidos no âmbito das Ciências Sociais Aplicadas, e em especial na área de Ciência da Informação. Através da interação entre os polos: epistemológico, teórico, técnico e morfológico, que fundamentam este método, houve o fortalecimento e a fluidez das questões estudadas. Os resultados dos questionários aplicados aos bibliotecários, bem como da análise dos sítios das bibliotecas pesquisadas, foram interpretados através de um alicerce teórico baseado em três pontos principais: as questões paradigmáticas que envolvem a área de Ciência da Informação, a análise da mediação pós-custodial informacional e científica e as Tecnologias de Informação e Comunicação presentes nas bibliotecas. Como principais resultados vemos que o impacto das tecnologias digitais nas bibliotecas universitárias é considerado pelos bibliotecários brasileiros e portugueses como positivo, com ênfase em dois pontos: a inovação dos suportes de informação e a autossuficiência dos utilizadores. A maior diferença se percebe em relação ao aspecto social, através de uma maior preocupação entre os bibliotecários brasileiros com as barreiras informacionais causadas por questões econômica, social e educacional e sentido com menos intensidade pelos bibliotecários portugueses, que ascendem as tecnologias digitais com mais facilidade. De forma conclusiva, a análise do impacto e a mediação das tecnologias digitais nas bibliotecas pesquisadas, apontam para uma evolução nas práticas mediadoras das bibliotecas universitárias de Portugal e do Nordeste do Brasil e uma convergência laboral entre os bibliotecários portugueses e brasileiros.

O uso do móbile marketing como estratégia de fidelização de clientes :um estudo e empresas do setor de comércio e serviços em natal-RN

This study aims to understand the effects of the mobile marketing use as a relationships tool for companies that operate locally, because of the lack of information about this new marketing tool, as well as the scarcity of studies in this area. This is an exploratory and qualitatively study, based on primary sources, raised through books, articles in the marketing area and the telecommunications industry organs as well as secondary sources. With the purpose to look into the issue, a semi-structured interview is made with the companies managers of the sectors of trade and services in Natal-RN. The advances in technology allow an important discussion focused on the marketing in the new communication technologies scenario. It appears that the mobile marketing adoption and use by local companies is already a reality and companies are awake to changes and technological innovations accessible, especially the mobile telephony as well as convergence with other media. There is, however, that the use of technologies offered by mobile marketing is still limited to the sending of text messages (SMS), despite the numerous possibilities of it use. Moreover, the results obtained with mobile marketing use show that companies can identify them, but there is no effective monitoring in quantity and financial terms. Only affect sales growth and support for progress in loyalty with customers. It shows up that the mentality of not measuring the results still in the plan of changes and technological innovations. The data allow saying that the mobile marketing is a reality, however has not yet signed as a tool for carrying out campaigns and marketing tool for loyalty of customers, despite presenting a wide range of possibilities to streamline and make more effective the marketing businesses process

Estratégias internacionais da fruticultura do RN: o caso finobrasa processo e evolução

The present inquiry has as main objective to understand the process of formation of the international strategies of the exporting companies of fruits of the RN through the theory of the resource dependence. Aiming at to clarify as the companies they can carry through the process of internationalization through this theory had been study the behavior and economic theories of the process of internationalization of companies. Amongst the economic theories they are distinguished the eclectic paradigm of Dunning (1958), Vernon (1669) through the theory of the cycle of the product and Bucley and Casson (1979) with the theory of the international operations. In the mannering boarding they had been investigated the school of Upsala through Johanson and Valnhe (1977) with the concept of the increasing of the markets and in the distance psychic starts and the interaction of the purchaser-salesman of Hallen and Wiedersheim-Paul (1979). In this perspective it observes main the occured changes in the organization in function of this process, following the rules observed by the gradual ingression in the international market, having as base ways of entrances in the external market used by these companies, in view of the frist phase that the company presents of businesses. Ahead of you analyze of these theories the study searches to analyze the convergence of the concepts proclaimed for the theory of the dependence of resources (PFEFFER; SALANCIK, 1978). and strategies of internationalization of the companies. The research is characterized as qualitative case study which adopts and exploratory and analytical type, retrospective matrix. The adopted strategy is of case study and the unit of analysis consisting of the Finobrasa, pertaining company to the Vicunha Group. The main method of collection of data was halfstructuralized interview allied the documentary research that together had presented an empirical perspective of the internationalization process. The analysis and quarrel of the results understand the description and the interpretation of the one of the information through the technique of analyzes of content. Initially the historical of the exportation of fruits of the Rio Grande do Norte with the focus in the region Açu/Mossoró is presented and after that the information of the Finobrasa are presented as base of the study. The main events are identified that had constituted the phases of the strategical model of the company. It was observed that the dimensions most excellent amongst those proclaimed by the School of Uppsala had been the learning, staffs and the step-starts is sufficiently gifts in the reality of the company, as well as the aspects of strategical alliances since the consolidated relationship of the Vicunha Group create a more solid trajectory in the international market allied the conditions created windows of marked . One understands, therefore, that the investigated process still has base the theoretical theories of the internationalization strategies corroborating for the theoretical convergence of the rules proclaimed for the theory of the dependence of resources.

Grupo Totem: a infecção pela performance e a encenação performática

The issue of creating productions of hybrid matrices has demanded, for more than three decades, the attention of several theater theorists (COHEN: 1995; LEHMANN: 2007). The study of philosophers (DELEUZE & GUATTARI: 1995) has contributed for new concepts of the scene. These artistic practices, depending on the context, have been generating, more and more, new ways of staging. I will discuss the contamination caused by Antonin Artaud in contemporary theater, and the theater s infection by the performance, based on the thought of Barbara Browning (1995), from its capacity to penetrate and invade territories, and installs a new system. I affirm that the Totem Group (Recife PE) was contaminated by the performance and analyze two performative plays of the group, their points of convergence and separation. The first one is Ita, the search for the origin, the animal devir; the second is Caosmopolita, the body as a reflex of urbanity

Mover/se(r) a gênese do corpo entre/corpos e seus trajetos no processo coreográfico

This paper proposes a reflection on the body between/bodies, especially in contemporary dance, in their path that starts from the choreographic construction, permeating the body of the choreographer, the dancer s body and when fulfills themselves as artistic expression, the body of the spectator. Initially discusses the body in dance as a body/space for convergence, connectedness and continuity, from the thought of the Greek philosopher Epicurus of Samos, in dialogue with the thought of Maurice Merleau-Ponty, Gilles Deleuze and José Gil. Reflect about the creation of this body/space in the relationship choreographer/dancer using as connecting thread the experiences of the author in his artistic path. Finally describes the process of creating the scenic experiment (h)áporos, which constitutes the practice scene of this dissertation, having as main objective the creation of spaces of convergence and interaction between a proponent and an affluent body that, in this move, transforms itself and the space that now cohabits / is

Simulação do escoamento monofásico em um estágio de uma bomba centrífuga utilizando técnicas de fluidodinâmica computacional

Oil production and exploration techniques have evolved in the last decades in order to increase fluid flows and optimize how the required equipment are used. The base functioning of Electric Submersible Pumping (ESP) lift method is the use of an electric downhole motor to move a centrifugal pump and transport the fluids to the surface. The Electric Submersible Pumping is an option that has been gaining ground among the methods of Artificial Lift due to the ability to handle a large flow of liquid in onshore and offshore environments. The performance of a well equipped with ESP systems is intrinsically related to the centrifugal pump operation. It is the pump that has the function to turn the motor power into Head. In this present work, a computer model to analyze the three-dimensional flow in a centrifugal pump used in Electric Submersible Pumping has been developed. Through the commercial program, ANSYS® CFX®, initially using water as fluid flow, the geometry and simulation parameters have been defined in order to obtain an approximation of what occurs inside the channels of the impeller and diffuser pump in terms of flow. Three different geometry conditions were initially tested to determine which is most suitable to solving the problem. After choosing the most appropriate geometry, three mesh conditions were analyzed and the obtained values were compared to the experimental characteristic curve of Head provided by the manufacturer. The results have approached the experimental curve, the simulation time and the model convergence were satisfactory if it is considered that the studied problem involves numerical analysis. After the tests with water, oil was used in the simulations. The results were compared to a methodology used in the petroleum industry to correct viscosity. In general, for models with water and oil, the results with single-phase fluids were coherent with the experimental curves and, through three-dimensional computer models, they are a preliminary evaluation for the analysis of the two-phase flow inside the channels of centrifugal pump used in ESP systems

Gestão compartilhada de P&D em petróleo:a interação entre a Petrobrás e a Universidade Federal do Rio Grande do Norte

This work addresses the relationship between University-Firm aims to understand the model of shared management of R&D in petroleum of Petrobras with UFRN. This is a case study which sought to investigate whether the model of cooperation established by the two institutions brings innovation to generate technical-scientific knowledge and contribute to the coordination with other actors in the promotion of technological innovation. In addition to desk research the necessary data for analysis were obtained by sending questionnaires to the coordinators of projects in R&D at the company and university. Also, interviews were conducted with subjects who participated in the study since its inception to the present day. This case study were analysed through the Resource-Based View and Interorganizational Networks theory. The sample data also stands that: searches were aligned to the strategic planning and that 29% of R&D projects have been successful on the scope of the proposed objectives (of which 11% were incorporated into business processes); which was produced technical and scientific knowledge caracterized by hundreds of national and international publications; thesis, dissertations, eleven patents, and radical and incremental innovations; the partnership has also brought benefits to the academic processes induced by the improved infrastructure UFRN and changing the "attitude" of the university (currently with national prominence in research and staff training for the oil sector). As for the model, the technical point of view, although it has some problems, it follows that it is appropriate. From the viewpoint of the management model is criticized for containing an excess of bureaucracy. From the standpoint of strategic allocation of resources from the legal framework needs to be reassessed, because it is focused only on the college level and it is understood that should also reach the high school given the new reality of the oil sector in Brazil. For this it is desirable to add the local government to this partnership. The set of information leads to the conclusion that the model is identified and named as a innovation of organizational arrangement here known as Shared Management of R&D in petroleum of Petrobras with UFRN. It is said that the shared management model it is possible to exist, which is a simple and effective way to manage partnerships between firms and Science and Technology Institutions. It was created by contingencies arising from regulatory stand points and resource dependence. The partnership is the result of a process of Convergence, Construction and Evaluation supported by the tripod Simplicity, Systematization and Continuity, important factors for its consolidation. In practice an organizational arrangement was built to manage innovative university-industry partnership that is defined by a dyadic relationship on two levels (institutional and technical, therefore governance is hybrid), by measuring the quarterly meetings of systematic and standardized financial contribution proportional to the advancement of research. These details have led to the establishment of a point of interaction between the scientific and technological-business dimension, demystifying they are two worlds apart
