Simulação computacional como ferramenta de auxílio ao projeto: aplicação em edifícios naturalmente ventilados no clima de Natal/RN

Natural air ventilation is the most import passive strategy to provide thermal comfort in hot and humid climates and a significant low energy strategy. However, the natural ventilated building requires more attention with the architectural design than a conventional building with air conditioning systems, and the results are less reliable. Therefore, this thesis focuses on softwares and methods to predict the natural ventilation performance from the point of view of the architect, with limited resource and knowledge of fluid mechanics. A typical prefabricated building was modelled due to its simplified geometry, low cost and occurrence at the local campus. Firstly, the study emphasized the use of computational fluid dynamics (CFD) software, to simulate the air flow outside and inside the building. A series of approaches were developed to make the simulations possible, compromising the results fidelity. Secondly, the results of CFD simulations were used as the input of an energy tool, to simulate the thermal performance under different rates of air renew. Thirdly, the results of temperature were assessed in terms of thermal comfort. Complementary simulations were carried out to detail the analyses. The results show the potentialities of these tools. However the discussions concerning the simplifications of the approaches, the limitations of the tools and the level of knowledge of the average architect are the major contribution of this study

O tema no processo criativo da asmarias companhia de teatro

Seted in the context of the educational actions of Casa Renascer, a non-governmental organization, located in Natal city, which had as its primary purpose the care with children and adolescent girls in vulnerable situations, this research is based on describing and analysis on the topic in the creative process developed by Asmarias Theatre Company from 1993 to 2003, a process that culminated in the assembly of the dramatic text, Mateus e Mateusa, of Qorpo-Santo. In this research is focused on the route of the Theatre Company has done so much theater in its early history (1993), with the practice of reading and dramatic writing in the preparation of didactic material called Primer of Inventions, as in the procedures with theater street and forum theater (1997 to 2000) to the reunion in 2001 of seven teenagers which articulated the last group formation next to the assembly's text Qorpo-Santo (2002- 2003). During the development on this learning, the evolution of the creative process based on institutional theme when asked if one can provide moments of educational experiences through the traditional form of theater, with reference to the issues inherent in the dramatic texts considered classics. The debate on the issue through research and analysis in its descriptions and finds in the interim between his past and present indications that lead to conclusive guises. The methodology, which is guided by research, is based in theatrical archeology (PAVIS, 2005), the evidential paradigm (GINZBURG, 1989) and the second approaches the experiences narrated by Benjamin (1985). We selected documents in formats of written texts, photographic and filmed, and identified in these files, marks and tracks which took us to understand the subject in the creative process of Asmarias Theatre Company during the tests with the dramatic text, Mateus and Mateusa, of Qorpo-Santo. In this theatrical practice, located in the field of the theater pedagogy, it appears that the actions across thematic theater in the Casa Renascer and allowed the formation of critical aesthetic perspective and personal social dimension of the subjects involved. The theme has gained a significant proportion in the theatrical activity as a guiding point of the creative process of Theatre Company, taking in the theatrical art form. In this sense, the creative process with the dramatic and classic texts won the educational dimension to address the issue in the movement of the drama as the focus of individual creation which added to the collective universe of the interactive game

Trajetos cênicos do grupo parafolclórico da UFRN:que dança é essa?

This paper aims at studying UFRN Parafolclórico Group, whose aesthetic formation is subjected to our analysis, specially at its two last performances, that is, Flor do Lírio (Lily Flower), 2004, and Debaixo do Barro do Chão (Under the Mud of the Ground), 2008. Three targets are envisaged here: to analyze the aesthetic ideas backing Parafolclórico Group exhibitions; to evaluate how their many folk elements interact with different artist languages in order to compose a certain choreography; and finally, to identify the aesthetic conformation placed behind the two different choreographs of the last performances, their trends and innermost features that differentiate them. In accordance with the Analysis of Contents (BARDIN, 2006), interviews have been made with the choreographers and the staff of the spectacles, resulting in elucidating answers to the understanding of their thematic axis. On the first chapter we called attention to motivating subjects as recollection, personal experiences, bibliography research, research in loco regarded as propelling forces of the creative works. Herein, folk culture is depicted as a dynamic process opening a frank dialogue with contemporary events and reinforcing their continuity. On the second chapter, we approached the aesthetic conformation and the scenic elements (costumes, light, scenario, make-up), integrating the studied spectacles and disseminating folk songs in various ways. As what concerns the subjects discourse, we have obtained support in authors like Robatto (1994); Lobo; Navas (2008); Burke (1989); Canclini (2006); Dufrenne (2005); Medeiros (2005); Pavis (2005); Silva (2005), among others. Those authors have provided us with an indispensable theoretic support which, added to the interviews, convinced us that the Parafolclórico Group s aesthetic conception tends to identify itself with the artist languages and other techniques of that Group. It also made sure that the Group s course aims at an aesthetic conception which is not limited to popular culture manifestations, like dance, but admits to play with other media in order to communicate its art. In view of this situation, we arrived to two conclusions: first: the group s interchanges emphasize the dynamic character of popular culture which, by establishing contacts with different realities, receives influences capable of extending its own continuity; second: the contemporary state of arts also improves multiple interchanges opening way, so, for many accomplishments in their field. Therefore, UFRN Parafolclórico Group inserts itself in the contemporary scenery by performing new evaluations of the popular dances as long as it puts them in contact with different technical, aesthetic, artist and culture combinations

Leitora-criadora: a experiência situada na construção dramatúrgica

This study has the purpose of investigating the term reader-creator , on the textual aspects of the dramatical works A Morte nos Olhos , A Memória Ferida and Na Outra Margem (2010) by Antonia Pereira Bezerra. In this sense, we propose an analysis of these works based on author‟s life experience as creative matter for a autofictional narrative, highlighting the relations between the autobiographical elements (LEJEUNE, 2008; DOSSE, 2009) and fictional elements in the construction of dramatic narratives. The theoretical analysis pervades the studies fields of Reception Aesthetics (ISER, 1996), memory (RICOUER, 2007) and narrative (RICOEUR, 2010), evidencing the relation between the author and the pursuit of her memories and life experiences, the matter to elaboration of writing. Then we intend thinking a reader-creator of herself, that at the same time she seeks in her memories the biographic aspects to her narrative, she converts this reality with the insertion of fictional elements from the imagination (SARTRE, 2008)

Caldo do caldo: memória do espetáculo de dança paraibano caldo da cana

This research investigated the dance piece Caldo da Cana which premiered in João Pessoa-PB, in September 1984. It problematizes theoretical and practical way to make dance history, investigating this possibility through the dance itself. Arises from the fact that the dance has specific characteristics that can not be neglected by the historical account. In this sense, it was initiated by the raising of a theoretical framework that speaks to the indicated issues and unfolds through a field study, which included collecting testimonies from people who participated in the show, documentary research, gathering material traces and finally consists a practical part by transposing elaborated historical knowledge into the body through a creative process, resulting on this moment, in the construction of a duo dance

Utilização de resíduo lignocelulósico na obtenção de chapa de madeira aglomerada homogênea e compósito reforçado com fibra de vidro-E

This research is about the use of the coconut´s endocarp (nucifera linn) and the waste of derivatives of wood and furniture as raw material to technological use. In that sense, the lignocellulosic waste is used for manufacture of homogeneous wood sheet agglomerate (LHWS) and lignocellulosic load which take part of a polymeric composite with fiber glass E (GFRP-WC). In the manufacturing of the homogeneous wood sheet agglomerate (LHWS), it was used mamona´s resin as waste s agglutinating element. The plates were taken up in a hydraulic press engine, heated, with temperature control, where they were manufactured for different percentage of waste wood and coconuts nucífera linn. Physical tests were conducted to determine the absorption of water, density, damp grade (in two hours and twenty-four hours), swelling thickness (in two hours and twenty-four hours), and mechanical tests to evaluate the parallel tensile strength (internal stick) and bending and the static (steady) flexural. The physical test´s results indicate that the LHWS can be classified as bonded wood plate of high-density and with highly water resistant. In the mechanical tests it was possible to establish that LHWS presents different characteristics when submitted to uniaxial tensile and to the static (steady) flexural, since brittle and elasticity module had a variation according to the amount of dry endocarp used to manufacture each trace of LHWS. The GFRP-WC was industrially manufactured by a hand-lay-up process where the fiber glass E was used as reinforcement the lignocellulósic´s waste as load. The matrix was made with ortofitalic unsaturated polyester resin. Physical and mechanical tests were performed in presence of saturated humidity and dry. The results indicated good performance of the GFRP-WC, as traction as in flexion in three points. The presence of water influenced the modules obtained in the flexural and tensile but there were no significant alteration in the properties analyzed. As for the fracture, the analysis showed that the effects are more harmful in the presence of damp, under the action of loading tested, but despite this, the fracture was well defined starting in the external parts and spreading to the internal regions when one when it reaches the hybrid load

Compósitos poliméricos a base de fibras de licuri: efeitos da hibridização e do envelhecimento ambiental acelerado

The gradual replacement of conventional materials by the ones called composite materials is becoming a concern about the response of these composites against adverse environmental conditions, such as ultraviolet radiation, high temperature and moist. Also the search for new composite using natural fibers or a blend of it with synthetic fibers as reinforcement has been studied. In this sense, this research begins with a thorough study of microstructural characterization of licuri fiber, as a proposal of alternative reinforcement to polymeric composites. Thus, a study about the development of two composite laminates was done. The first one, involving only the fiber of licuri and the second comprising a hybrid composite based of fiber glass E and the fiber of licuri, in order to know the performance of the fiber when of fiber across the hybridization process. The laminates were made in the form of plates using the tereftálica ortho-polyester resin as matrix. The composite laminate made only by licuri fiber had two reinforcing fabric layers of unidirectional licuri and the hybrid composite had two reinforcing layers of unidirectional licuri fabric and three layers of fiber short glass-E mat. Finally, both laminates was exposed to aging acceleration in order to study the influence of environmental degradation involving the mechanical properties and fracture characteristics thereof. Regarding the mechanical properties of composites, these were determined through uniaxial tensile tests, uniaxial compression and three bending points for both laminates in original state, and uniaxial tensile tests and three bending points after accelerated aging. As regards the study of structural degradation due to aging of the laminates, it was carried out based on microscopic analysis and microstructure, as well as measuring weight loss. The characteristics of the fracture was performed by macroscopic and microscopic (optical and SEM) analysis. In general, the laminated composites based on fiber licuri showed some advantages in their responses to environmental aging. These advantages are observed in the behavior related to stiffness as well as the microstructural degradation and photo-oxidation processes. However, the structural integrity of this laminate was more affected in case the action of uniaxial tensile loads, where it was noted a lower rate of withholding his last resistance property

Formulação de bloco intertravado cerâmico com adição de resíduos urbanos e industriais

The production of waste from urban and industrial activities is one of the factors of environmental contamination and has aroused attention of the scientific community, in the sense of its reuse. On the other hand, the city of Salvador/Ba, with approximately 262 channels, responsible for storm water runoff, produces every year, by the intervention of cleaning and clearing channels, a significant volume of sediments (dredged mud), and thus an appropriate methodology for their final destination. This study aims to assess the influence of incorporation of these tailings in arrays of clay for production of interlocked block ceramic, also known as ceramic paver. All the raw materials from the metropolitan region of Salvador (RMS) were characterized by x-ray fluorescence, x-ray diffraction, thermal analysis (TG and TDA), particle size analysis and dilatometry. With the use of statistical experimental planning technique, ternary diagram was defined in the study region and the analyzed formulations. The specimens were prepared with dimensions of 60x20x5mm³, by uniaxial pressing of 30 MPa and after sintering at temperatures of 900°, 1000º and 1100ºC the technological properties were evaluated: linear shrinkage, water absorption, apparent porosity, apparent specifies mass, flexural rupture and module. For the uniaxial compression strength used cylindrical probe body with Ø 50 mm. The standard mass (MP) was prepared with 90% by weight of clay and 10% by weight of Channel sediment (SCP), not being verified significant variations in the properties of the final product. With the incorporation of 10% by weight of manganese residue (PFM) and 10% by weight of the Ceramic waste (RCB) in the mass default, in addition to adjusting the plasticity due to less waste clay content, provided increased linear firing shrinkage, due the significant concentration of K2O, forming liquid phase at low temperature, contributing to decreased porosity and mechanical resistance, being 92,5 MPa maximum compressive strength verified. After extract test leachate and soluble, the piece containing 10% of the PFM, was classified as non-hazardous and inert material according to NBR10004/04 ABNT. The results showed the feasibility on using waste, SCP, RCB and PFM clay mass, at temperatures above 900ºC, paver ceramic production, according to the specifications of the technical standards, so that to exceed the 10% of the PFM, it becomes imperative to conduct studies of environmental impacts

Plásticos reforçados a base de tecidos híbridos: efeitos da anisotropia e geometria normativa na caracterização mecânica e da fratura

As most current studies, reinforced plastics have been, in recent years, a viable alternative in building structural elements of medium and large, since the lightness accompanied by high performance possible. The design of hybrid polymer composites (combination of different types of reinforcements) may enable structural applications thereof, facing the most severe service conditions. Within this class of composite materials, reinforced the underlying tissues hybrid high performance are taking space when your application requires high load bearing and high rigidity. The objective of this research work is to study the challenges in designing these fabrics bring these materials as to its mechanical characterization and fracture mechanisms involved. Some parameters associated with the process and / or form of hybridization stand out as influential factors in the final performance of the material such as the presence of anisotropy, so the fabric weave, the process of making the same, normative geometry of the specimens, among others. This sense, four laminates were developed based hybrid reinforcement fabrics involving AS4 carbon fiber, kevlar and glass 49-E as the matrix epoxy vinyl ester resin (DERAKANE 411-350). All laminates were formed each with four layers of reinforcements. Depending on the hybrid fabric, all the influencing factors mentioned above have been studied for laminates. All laminates were manufactured industrially used being the lamination process manual (hand-lay-up). All mechanical characterization and study of the mechanism of fracture (fracture mechanics) was developed for laminates subjected to uniaxial tensile test, bending in three and uniaxial compression. The analysis of fracture mechanisms were held involving the macroscopic, optical microscopy and scanning electron microscopy

Estudo in silico da interação da albumina de soro humano com o ibuprofeno

Currently, computational methods have been increasingly used to aid in the characterization of molecular biological systems, especially when they relevant to human health. Ibuprofen is a nonsteroidal antiinflammatory or broadband use in the clinic. Once in the bloodstream, most of ibuprofen is linked to human serum albumin, the major protein of blood plasma, decreasing its bioavailability and requiring larger doses to produce its antiinflamatory action. This study aimes to characterize, through the interaction energy, how is the binding of ibuprofen to albumin and to establish what are the main amino acids and molecular interactions involved in the process. For this purpouse, it was conducted an in silico study, by using quantum mechanical calculations based on Density Functional Theory (DFT), with Generalized Gradient approximation (GGA) to describe the effects of exchange and correlation. The interaction energy of each amino acid belonging to the binding site to the ligand was calculated the using the method of molecular fragmentation with conjugated caps (MFCC). Besides energy, we calculated the distances, types of molecular interactions and atomic groups involved. The theoretical models used were satisfactory and show a more accurate description when the dielectric constant ε = 40 was used. The findings corroborate the literature in which the Sudlow site I (I-FA3) is the primary binding site and the site I-FA6 as secondary site. However, it differs in identifying the most important amino acids, which by interaction energy, in order of decreasing energy, are: Arg410, Lys414, Ser 489, Leu453 and Tyr411 to the I-Site FA3 and Leu481, Ser480, Lys351, Val482 and Arg209 to the site I-FA6. The quantification of interaction energy and description of the most important amino acids opens new avenues for studies aiming at manipulating the structure of ibuprofen, in order to decrease its interaction with albumin, and consequently increase its distribution
