Argamassas do grupo escolar Augusto Severo/RN: caracterização e incidência de manifestações patológicas

The search for cultural heritage preservation should be a constant, in order to minimize the lost of historical and cultural identity of a country. As part of this cultural heritage, highlights the importance of historical buildings. For the principles of restoration are met its important to know the state of conservation and the existing materials. Given the above, this work aims to study the pathological manifestations of the mortar coating from the Grupo Escolar Augusto Severo. For this, was conducted historical survey of the building, on-site visits with visual observation, collecting samples of mortar coating and characterization through visual and laboratory analysis, XRF, XRD, TG/DTG, OM and SEM-EDS. From the observations, pathological manifestations were found as: cracks, detachment of the coating, dirt, use of inappropriate material basis of cement, efflorescence, mold and mildew and also incompatible material base of cement. It was found that the pathological manifestations were intensified due to lack of coverage in some spots and especially the abandonment of the building, that many years does not have restoration or any other type of preventive and corrective maintenance. The results of laboratory tests indicated that the mortars studied are based on lime, with calcitic nature, and siliceous aggregate, with the presence of clay in two samples. From the samples collected, two are composed of lime, sand and clay and two by lime and sand. In this regard, it is important to conduct periodic inspections and maintenance, as well as carrying out restoration with use of material compatible with the original

Análise antropotecnológica do desenvolvimento de novos produtos na produção artesanal : caso das rendeiras de bilro da Vila de Ponta Negra em Natal, RN

Brazilian craft production plays an important role in the generation of employment and income for many families in every state across Brazil. In Natal, Rio Grande do Norte, Brazil, among many types found, identifies itself with the production of bobbin-lace, still practiced in Ponta Negra Village for ancient craftswomens of city that try to preserve the art and tradition of bobbin-lace. This work presents the results of an analysis conducted based in concepts of anthropotechnology, on the effects of a design workshop held with bobbin-lace craftswomen in the village of Ponta Negra in July of 2006. The workshop was intended to propose a new concept of products and a new alternative for production in the activity of the craftswomen, on the premise that the laces could be used as a detail inserted into other industrial products such as shirts, bags, towels, etc. Evaluations after the workshop showed that none of the artisans continued to work, indicating that actions focused solely on products did not generate representative results in the production of bobbin-lace. Evaluations also indicated that knowledge about the artisan's personal and professional characteristics, organization, pace, workload, and cultural and historical issues that permeate the activity are essential to the success of technology transfer, particularly when the transfer affects the craft production as it relates to the inseparable aspects of the craftswomen's work and lifestyle

Análise funcional do design das órteses para rizartrose

The purpose of this paper is to identify the utilization of two models of orthotics used in the conservative treatment of rizartrose in patients/consumers that were referred by the medical clinic to the LAI (Laboratory of Integrated Accessibility). It describes this group s perception related to the functional aspects of the two models, evaluates the value of the product attributed by the patient/consumer and describes the importance attributed to each model. The research s objective consists in identifying which model this is preferred from the point of view by the patients that use either the dorsal or ventral models used in the conservative treatment of rizartrose . This work is then based on the exploratory research through the investigation of the bibliography available and in the research field. The research field used the case study methodology to investigate the phenomenon in the real context. The data were collected using a patient questionnaire during two times after the use of the dorsal orthotic and after the use of the ventral orthotic. The questionnaire was used to identify the relationship between the patients/consumers and the two different types of orthotics. A general descriptive analysis was used in order to verify the patient s abilities executing certain activities daily living using the dorsal and ventral orthotics, the product s functional aspects and its value from the patient s/consumer s point of view. The results show that the preference for the dorsal or ventral models is determined by the individual needs of each person. The results also show that other variables, such as the use of the orthotic on the dominant or non-dominant hand, play a role in the preferred model by the patient/consumer and need to be further investigated

Group Sequential Communication (GSC): Especificação e Análise de Desempenho de umMecanismo de Comunicação de Tempo Real Compatível ao Padrão IEEE 802.11/11e Aplicado à Automação Industrial

This thesis proposes the specification and performance analysis of a real-time communication mechanism for IEEE 802.11/11e standard. This approach is called Group Sequential Communication (GSC). The GSC has a better performance for dealing with small data packets when compared to the HCCA mechanism by adopting a decentralized medium access control using a publish/subscribe communication scheme. The main objective of the thesis is the HCCA overhead reduction of the Polling, ACK and QoS Null frames exchanged between the Hybrid Coordinator and the polled stations. The GSC eliminates the polling scheme used by HCCA scheduling algorithm by using a Virtual Token Passing procedure among members of the real-time group to whom a high-priority and sequential access to communication medium is granted. In order to improve the reliability of the mechanism proposed into a noisy channel, it is presented an error recovery scheme called second chance algorithm. This scheme is based on block acknowledgment strategy where there is a possibility of retransmitting when missing real-time messages. Thus, the GSC mechanism maintains the real-time traffic across many IEEE 802.11/11e devices, optimized bandwidth usage and minimal delay variation for data packets in the wireless network. For validation purpose of the communication scheme, the GSC and HCCA mechanisms have been implemented in network simulation software developed in C/C++ and their performance results were compared. The experiments show the efficiency of the GSC mechanism, especially in industrial communication scenarios.

Análise de escalabilidade de uma implementação paralela do simulated annealing acoplado

This paper analyzes the performance of a parallel implementation of Coupled Simulated Annealing (CSA) for the unconstrained optimization of continuous variables problems. Parallel processing is an efficient form of information processing with emphasis on exploration of simultaneous events in the execution of software. It arises primarily due to high computational performance demands, and the difficulty in increasing the speed of a single processing core. Despite multicore processors being easily found nowadays, several algorithms are not yet suitable for running on parallel architectures. The algorithm is characterized by a group of Simulated Annealing (SA) optimizers working together on refining the solution. Each SA optimizer runs on a single thread executed by different processors. In the analysis of parallel performance and scalability, these metrics were investigated: the execution time; the speedup of the algorithm with respect to increasing the number of processors; and the efficient use of processing elements with respect to the increasing size of the treated problem. Furthermore, the quality of the final solution was verified. For the study, this paper proposes a parallel version of CSA and its equivalent serial version. Both algorithms were analysed on 14 benchmark functions. For each of these functions, the CSA is evaluated using 2-24 optimizers. The results obtained are shown and discussed observing the analysis of the metrics. The conclusions of the paper characterize the CSA as a good parallel algorithm, both in the quality of the solutions and the parallel scalability and parallel efficiency

Estudo da topologia de redes de conexão funcional no córtex sensorial primário e hipocampo durante o sono de ondas lentas

Complex network analysis is a powerful tool into research of complex systems like brain networks. This work aims to describe the topological changes in neural functional connectivity networks of neocortex and hippocampus during slow-wave sleep (SWS) in animals submited to a novel experience exposure. Slow-wave sleep is an important sleep stage where occurs reverberations of electrical activities patterns of wakeness, playing a fundamental role in memory consolidation. Although its importance there s a lack of studies that characterize the topological dynamical of functional connectivity networks during that sleep stage. There s no studies that describe the topological modifications that novel exposure leads to this networks. We have observed that several topological properties have been modified after novel exposure and this modification remains for a long time. Major part of this changes in topological properties by novel exposure are related to fault tolerance

Análise de desempenho de um refrigerador de pequeno porte com drop in de refrigerantes hidrocarbonetos

From what was stated in the Montreal Protocol, the researchers and refrigeration industry seek substitutes for synthetic refrigerants -chlorofluorocarbons (CFCs) and HCFCs (HCFC) - that contribute to the depletion of the ozone layer. The phase-out of these substances was started using as one of the replacement alternatives the synthetic fluids based on hydro fluorocarbons (HFCs) that have zero potential depletion of the ozone layer. However, contribute to the process of global warming. HFC refrigerants are greenhouse gases and are part of the group of gases whose emissions must be reduced as the Kyoto Protocol says. The hydrocarbons (HC's), for not contribute to the depletion of the ozone layer, because they have very low global warming potential, and are found abundantly in nature, has been presented as an alternative, and therefore, are being used in new home refrigeration equipment in several countries. In Brazil, due to incipient production of domestic refrigerators using HC's, the transition refrigerants remain on the scene for some years. This dissertation deals with an experimental evaluation of the conduct of a drinking fountain designed to work with HFC (R-134a), operating with a mixture of HC's or isobutane (R-600a) without any modification to the system or the lubricating oil. In the refrigeration laboratory of Federal University of Rio Grande do Norte were installed, in a drinking fountain, temperature and pressure sensors at strategic points in the refrigeration cycle, connected to an acquisition system of computerized data, to enable the mapping and thermodynamics analysis of the device operating with R-134a or with a mixture of HC's or with R-600a. The refrigerator-test operating with the natural fluids (mixture of HC's or R-600a) had a coefficient of performance (COP) lower than the R-134a

Análise técnica e econômica do processo de obtenção de espaguetes com adição de farinha de trigo integral e farinha de linhaça

This work studies the fabrication of spaghetti through the process at high temperatures through the use of flour added to flour and flaxseed meal, with the aim of evaluating the final product quality and estimate the cost of production. The values of moisture, ash, protein, wet gluten, gluten index, falling number and grain of flour and mixtures to test to be the possible use in mass manufacturing and technological criteria for compliance with current legislation. Spaghetti noodles type were manufactured by adding 10% and 20% flour and 10% and 20% flaxseed meal with performance of physical-chemical, sensory and rheological properties of the products. Further analysis was performed on the product acceptance and estimation of production cost in order to create subsidies to enable the introduction of products with greater acceptance and economic viability in the market by the food industry. On the rheology of the product test was cooking the pasta, specifying the volume increase, cooking time and percentage of solid waste. In the sensory evaluation was carried out the triangular test of product differentiation with 50 trained judges and acceptance testing by a hedonic scale with evaluation of the aspects color, taste, smell and texture. In defining the sensory profile of the product was performed with ADQ 9 judges recruited and trained at the factory, using unstructured scale of 9 cm, assessing the attributes of flavor of wheat, flax flavor, consistency, texture of raw pasta, raw pasta color and color of cooked pasta. The greater acceptance of product quality was good and the pasta with 20% flour, 10% followed by the full product, 10% and 20% flaxseed characterized the average quality of the criterion of loss analysis of solids, together with mass full commercial testing. In assessing the estimated cost of production, the two products more technologically feasible and acceptable (20% whole and 10% flaxseed) were evaluated in high temperature processes. With total cost of R $ 4,872.5 / 1,000 kg and R $ 5,354.9 / 1,000 kg respectively, the difference was related to the addition of lower inputs and higher added value in the market, flour and flaxseed meal. The comparative analysis of cases was confirmed the reduction in production time (10h), more uniform product to the drying process at high temperature compared to conventional

O discurso dos tuiteiros: uma análise crítica da construção identitária coletiva e do empoderamento cidadão

Los cambios sociales y culturales que caracterizan el mundo contemporáneo sorprendieron estudiosos de todas las áreas. Los avances tecnológicos principalmente en el área de transmisión de informaciones revolucionaron las nociones de tiempo y espacio. Nuevos medios de comunicación, favorecidos principalmente por la llegada de Internet, abrieron espacios de expresión para ciudadanos deseosos de ser oídos. Aún coexistiendo con los medios de comunicación tradicionales, los nuevos espacios representan una oportunidad de libertad de expresión, de interacción sin mediaciones y de construcción de contenidos independientes. Movimientos sociales se organizan a través de estos nuevos medios de comunicación y desarrollan un activismo que comienza en forma virtual y se extiende a movilizaciones presenciales. Castells (2009) llama de auto comunicación de masas a ese proceso de producir y difundir informaciones que antes era propiedad exclusiva de los medios de comunicación tradicionales. Natal, fue escenario de la gestación y articulación virtual de un movimiento denominado Fora Micarla cuyo objetivo ha sido lograr el impeachment de la alcaldesa de la ciudad, Micarla de Souza. Aunque el objetivo principal no fue alcanzado, el movimiento formó parte de los procesos de cambio social que llevaron los ciudadanos al ciberactivismo. El Fora Micarla se constituye también como un cambio social en sí mismo al colaborar en la consolidación de la identidad colectiva de un grupo de jóvenes universitarios en busca de justicia social. El Twitter fue el principal canal de expresión del grupo y responsable por la rápida expansión de las movilizaciones. El Abordaje Sociológico y Comunicacional del Discurso (ASCD) ha aportado el marco teórico de referencia utilizado en esta investigación. La Comunicación para el Cambio Social (GUMUCIO, 2008) y la Sociología Aplicada al Cambio Social (SACO, 2006) así como los estudios del sujeto y de las identidades (BAJOIT, 2006) forman la base de la ASCD para un estudio más completo de las prácticas discursivas. Considerando que el objeto de estudio son las manifestaciones discursivas de los usuarios simpatizantes del Movimiento Fora Micarla , y que la ASCD es un brazo del Análisis Crítico del Discurso, se hace necesario un análisis lingüístico de los textos. La Gramática Sistémica Funcional, a través del Sistema de Evaluación desarrollado por Martin and White (2004), ofrece los recursos para evaluar las manifestaciones por medio de tuítes de los integrantes del movimiento. La representación de los actores sociales (VAN LEUWEEN, 1998) complementa el análisis discursivo crítico de la ASCD. El empoderamiento ciudadano se materializa por medio de los cambios conquistados a través de los nuevos medios

Entre a fé, a obra social e a publicidade: uma análise crítica do discurso da responsabilidade social da Igreja Universal do Reino de Deus

Situated on Applied Linguistics (PENNYCOOK, 1998; MOITA LOPES, 2003, 2006, 2008, 2009), this thesis, which is inscribed in a qualitative-interpretative approach of a critical analysis perspective , lies on the speech of social responsibility and the way like that is employed in seeking for legitimacy and prestige within the neopentecostal brazilian religious field, more specifically of the Universal Church of the Kingdom of God. The general goal of this research is t reflect upon the speech on social responsibility and the rethoric of selfpromotion of the Universal Church through the role of social actors in the making of his her identities, materialized in the newspaper Folha Universal. In order to achieve that, we have conjugated, in this research, social and discursive analysis. On the linguistic-discursive approach, the research is based on the Critical Analysis of Discourse (ACD), specially in Fairclough (2001, 2003, 2006), a proposal that provides theoretical-methodological tools to investigate the language beyond the linguistic structures , that is, the discourse, social practices in which it occurs and more ample structures. Theoretical assumptions were also used of Sistemico-Functional Linguistics(LSF), matching with categories of the Transitivity System of Halliday (1994, 2004), of the forms of representation of social actors in the socioeconomic perspective by Van Leeuwen (1997, 2008) and of the Appraisal system by Martin and White (2005). As we develop the argumentation on thesobre social role of religion in this thesis, we make use of the authors such as Freston (1994), Oro (1997, 2003), Campos (1996, 1999), Mariano (1999), Meneses (2008), among several ones. We have also used a series of concepts and categories coming from the field of communication and marketing on the business social responsability and social marketing . In this area, we take as references the contributions of Bueno (2003), Fossá and Sartoretto (2003) and Zenone (2006). The corpus of the work is framed by news taken at the newspaper Folha Universal, in which are given the social responsibility actions of the church . The timeframe used was on the editions of 2010 thru 2012. Results found at he analysis of the News lead to semantic features of Assessment of Affection, Judgment and Appreciation, many times followed by Gradation, and the Attribution, one of the subsystems of the Attachment, are evidence of positive assessments for the Universal Church and its agents and make up rethorical elements which provide structure for the discourse of the Universal Church at the newspaper Folha Universal consisted of its image (style) of social responsibility . Results show that the most frequente social actors of the discourse are, on one hand, the Universal Church itself and its volunteers, famous (actors, actresses, presenters), politicians and authorities, on the other hand, the population which was helped by the Church social projects . The first group seems to be Always activated, however the second one, most of the time rather passive. These are also represented by assimilation in most of the occurrences, however the other ones by individualization and nomination entitled by honorification, except for the volunteers that are represented either as an individual, or as a group

Manual do professor, muito prazer em (re)conhecê-lo! Uma análise sociorretorica do gênero

Esta pesquisa de natureza documental e etnográfica se insere no campo da Linguística Aplicada, tendo por objeto de estudo o Manual do Professor, que acompanha o livro didático de Língua Portuguesa, e por objetivo geral (re)conhecer os aspectos sociorretóricos do gênero Manual do Professor. O interesse desta tese está concentrado no uso situado desse gênero, a partir do qual se observam seus aspectos sociorretóricos, a saber: o que está posto no produto, o ambiente de interação onde é encontrado e como é visto por seus usuários em potencial. Em um primeiro momento, produzimos um quadro epistemológico que nos permitiu, dentre outros reparos, (i) compreender gênero textual como ação retórica tipificada baseada numa situação retórica recorrente e (ii) obter um panorama dos programas de governo voltados para a avaliação de coletâneas didáticas, nos quais encontramos aspectos indispensáveis a um Manual do Professor. Os aportes teóricos adotados neste estudo referem-se à concepção sociorretórica dos estudos de gênero textual à luz, sobretudo, de Johns et al. (2006), Bazerman (2011) e Miller (2011). Em um segundo momento, sob o viés da abordagem sociorretórica, procuramos definir o Manual do Professor como gênero textual e apresentamos os aspectos retóricos encontrados nas amostras que analisamos, considerando a organização constitutiva, o contexto de uso desse gênero e as percepções de seus usuários autores e professores. A geração de dados deu-se inicialmente a partir da seleção de três exemplares de Manuais de coletâneas didáticas adotadas no IFRN; em seguida, no sentido de reconhecer as percepções dos usuários desse gênero, realizamos grupo focal com professores e entrevistamos o coautor de uma das coletâneas. Para análise dos dados, elegemos o método etnográfico de análise de gêneros postulado por Reiff (apud JOHNS et al, 2006), que nos permitiu analisar o objeto de estudo em contextos autênticos de uso do gênero. Nossos resultados mostram que o Manual do Professor está inserido num sistema de gêneros e no sistema de atividades profissionais de domínio do professor e não se limita apenas a explicar como está organizado o livro didático do aluno. Outros sete propósitos foram observados, dentre os quais se encontram: possibilitar ao docente uma reflexão sobre a sua prática de ensino e sugerir caminhos para a melhoria do processo de ensino-aprendizagem. Acreditamos que esta pesquisa poderá estimular professores, em relação à importância (e não obrigatoriedade) de consultas periódicas aos Manuais; autores, no que se refere a estabelecer uma interlocução mais pessoalizada com seus leitores em potencial e no sentido de esclarecer ainda mais as facetas do livro didático; e editoras, sobretudo no que tange a recursos de editoração, para que o Manual do Professor se torne mais atrativo

Análise das curvas de luz do CoroT usando diferentes processos comparativos: estimando períodos de rotação estelar

One of the main goals of CoRoT Natal Team is the determination of rotation period for thousand of stars, a fundamental parameter for the study of stellar evolutionary histories. In order to estimate the rotation period of stars and to understand the associated uncertainties resulting, for example, from discontinuities in the curves and (or) low signal-to-noise ratio, we have compared three different methods for light curves treatment. These methods were applied to many light curves with different characteristics. First, a Visual Analysis was undertaken for each light curve, giving a general perspective on the different phenomena reflected in the curves. The results obtained by this method regarding the rotation period of the star, the presence of spots, or the star nature (binary system or other) were then compared with those obtained by two accurate methods: the CLEANest method, based on the DCDFT (Date Compensated Discrete Fourier Transform), and the Wavelet method, based on the Wavelet Transform. Our results show that all three methods have similar levels of accuracy and can complement each other. Nevertheless, the Wavelet method gives more information about the star, from the wavelet map, showing the variations of frequencies over time in the signal. Finally, we discuss the limitations of these methods, the efficiency to give us informations about the star and the development of tools to integrate different methods into a single analysis

Análise da função dos músculos do quadril em portadores de síndrome da dor patelofemural

The Patellofemoral pain syndrome is defined as a fore or retro patellar pain and it has multifactorial etiology, where the bad patellar alignment is the most acceptable hypothesis. However proximal factors to the knee, as the debility of the muscles of the hip, have been demonstrated as a contributing factor to the appearing of that syndrome. Purpose: To evaluate if exists a relation between the hip muscles performance and the development of the SDPF. Methods: Thirty women took part in this study. They were divided in two groups; a control group (fifteen asymptomatic subjects) and an experimental group (fifteen subjects with the diagnosis of SDPF). The muscle performance was evaluated in an isokinetic dynamometer, where it was verified the peak torque (PT), PT to body weight, PT time and the agonist/antagonist relation. It was also analyzed the electromyographic activity of the middle gluteus. The data was analyzed by the not paired t test at a significance level of 5%. Results:. Didn t have significant difference to the PT of the abductor muscles (p = 0,46) and lateral rotators of the hip (p = 0,17) between groups. Also didn t have significant difference to the PT values by the body weight, to these muscle groups either (p = 0,10 e p = 0,11, respectively). Didn t have significant difference between the amplitude of the signal (p = 0,05) and the onset of medium gluteus (p = 0,25) between the groups. Conclusion: In the experimental conditions realized, the study didn t demonstrate a relation between performance the hip muscles behavior and the development of the SDPF
