Aspetos do dimensionamento de painéis prefabricados de fachada em GRC do tipo nervurado

O recurso a sistemas de fachadas prefabricadas no ramo da Construção Civil tem-se revelado uma opção eficaz, apresentando-se como uma solução de vanguarda no sentido de garantir vantagens ao nível da qualidade e da produtividade. A introdução de painéis de GRC (Glassfibre Reinforced Concrete) no mercado da construção trouxe vantagens ao sector uma vez que compatibiliza as vantagens da prefabricação leve, elevados níveis de desempenho e uma grande latitude em termos de formas e acabamentos. Este compósito é formado por uma matriz de argamassa reforçada com fibra de vidro. A incorporação das fibras permite melhorar as propriedades mecânicas da argamassa, principalmente ao nível da resistência de tração e flexão, fazendo com que os elementos possam ter menores espessuras e consequentemente menor peso, comparativamente com peças de betão armado. No mercado são comercializados três tipos de painéis de GRC, os do tipo nervurado, os do tipo stud frame e os do tipo sanduiche. Estes vários tipos de painéis tem as suas particularidades e a seleção depende das exigências e das características da obra. O estudo teve como alvo diferentes formas e dimensões de painéis de fachada em GRC do tipo nervurado. No presente trabalho faz-se um estudo comparativo da aplicação de dois métodos de dimensionamento. Comparam-se os resultados obtidos pela teoria clássica da flexão (TCF) e pelo método dos elementos finitos (MEF) e confrontam-se estes valores com os resultados obtidos em ensaios. Com o estudo efetuado conclui-se pela validade e utilidade da análise através da TCF, cujos resultados se aproximam bastante da análise pelo MEF. Sugerem-se coeficientes de ajustamento no sentido de adaptar a pratica de projeto em conformidade com os resultados verificados.

A COMUNICAÇÃO DE MERCADO E OS BENS DE CAPITAL: estratégias e desafios do setor de equipamentos para construção

O setor de máquinas e equipamentos para construção civil utilizados em obras de grande porte tem uma participação expressiva tanto na economia brasileira como na cadeia produtiva da construção civil. Trata-se de um setor hipercompetitivo, composto por indústrias transnacionais que têm no marketing de relacionamento e nas estratégias B2B os principais pilares de sustentação de estratégia de comunicação com o mercado. Utilizando como técnica o estudo de caso múltiplo do qual fizeram parte três dos maiores fabricantes de equipamentos para construção instalados no Brasil Caterpillar, Case e Volvo o estudo mostra como e porque essas empresas optaram por privilegiar o marketing de relacionamento e a imagem da marca, em detrimento de outras competências de comunicação, como forma de construir relacionamentos estáveis, fiéis e de longo prazo com seus clientes.

Contribuição ao estudo avançado das argamassas de alto desempenho para reparos estruturais

Inúmeras estruturas de concreto no Brasil e no mundo estão atingindo o limite de sua vida útil projetada, completando um ciclo de cinco ou mais décadas de uso e operação. Além das estruturas mais antigas, existem ainda estruturas com reduzido tempo de serviço, e qualidade discutível, que já apresentam patologias em estado tão avançado que chegam a comprometer o seu desempenho. Vindo ao encontro dessas necessidades e no sentido de contribuir para o avanço científico e tecnológico do setor, este trabalho apresenta um método para dosagem, preparo e aplicação de argamassas de alto desempenho para recuperação de estruturas deterioradas, além de sugerir procedimentos para a realização desses reparos, fomentando a cultura das manutenções preventivas e desmistificando a complexidade atribuída a tais operações. Para tanto, foram realizados ensaios mecânicos, microestruturais e relacionados à durabilidade em corpos-de-prova moldados com sílica ativa e látex de estireno-butadieno. Os resultados indicaram que a adoção desses ingredientes, na composição da argamassa de reparo, provocou uma redução significativa da permeabilidade total e descontinuidade de poros, assim como promoveu uma melhor integridade dos constituintes da argamassa, traduzindo-se em uma ampliação, expressiva, das suas capacidades mecânicas. Quando comparada aos produtos industrializados da construção civil, com padrões similares, proporcionou uma economia da ordem de 85%, que permitiria recuperar, com os mesmos custos, quase cinco vezes mais estruturas comprometidas. Este estudo, de viés altamente tecnológico, vem oferecer à construção civil uma argamassa polimérica de alto desempenho, com função reparadora e custo mais acessível, que pode ser adotada em canteiros de obras, implementando ações de natureza sustentável e ainda atendendo às atuais exigências elencadas pela literatura, relacionadas à desempenho, vida útil e durabilidade das estruturas reparadas.

Princípios da construção enxuta no processo de planejamento de uma construtora de grande porte de Natal (RN)

Considered as one of the oldest activities done by men, the civil construction represents one of the most important sectors for the economic growth of a country, in spite of the low results of growth in the past few years and also in the current year. To make this industry grow, even with an unfavourable economic scenario, it is necessary to implement an effective planning in its activities. This is one of the most important concepts brought by the Lean Construction philosophy, which had its origin through the adaptation of the concepts established by the Toyota Production System (TPS) or Lean Production. By having as a scenario the city of Natal\RN, the main goal of this dissertation consists in investigating how the 11 principles of the lean construction influenced the schedule of a construction field that started to implement its lean concepts. As a methodology, it was used the case study of a big enterprise located in Natal (RN). During the execution of the method, documents related to the short-term, midterm and long-term planning were analysed , aiming to describe its planning process; it was also described the factors that caused the delays at the enterprises’ field ;in addition, a comparison was made between the results obtained at the case study and the ones presented at the literature; in the end, the actions were listed by the company, which had the purpose to solve the main causes of delays, verifying if they were linked to the lean construction principles. This research finds its reason of existence in the relevance of its theme at the nowadays reality of the construction industry, since the principles of the lean construction uphold the reduction of processes that are useless, diminishing wastes as well as costs in construction. The relevance is perceived for the academy, in terms of the possibility to discuss if the concepts established by the lean production are being adapted to the civil construction sector and how this adaptation is influencing at the buildings planning project. Economic importance, because with the reduction of the wastes and costs, the companies may reduce the building´s value into a more accessible value, even with the sector´s lower growth. And social significance, because lean construction gives a better participation of the labour at the planning activity. Among the main results, the high frequency of planning errors stands out, mainly the programming deviations and not the task programming, as well as the execution errors, low productivity and activities executed by the workers. Amongst the 11 principles of lean construction, only five were related with the 12 actions analysed by the author. From the 12 actions, four were completely cohesive to one or more from these five principles. Some improvement proposals were also highlighted and established by the research.

Avaliação da conformidade dos blocos cerâmicos produzidos em algumas cerâmicas no Rio Grande do Norte

The final quality of the works accomplished by the building construction industry depends directly on the quality of the materials supplied and used during all their phases of execution. The federal government participation and several state programs have established conditions to stimulate and require the increment of the quality level in the building construction industry´s product chain. These programs aim at the product conformity to the technical standards. Within this context, the evaluation program of the ceramic product conformity in Rio Grande do Norte state is assessing the conformity degree to Brazilian Technical Standards of ceramic bricks and tiles made in the ceramic production area in the state. In this work, is determine the degree of conformity of the sealing ceramic bricks made by some companies in different areas of the state, such as Assú, São Gonçalo do Amarante, Apodi, Parelhas, São José do Mipibu e Macaíba. Using the technical standards as a point of reference, we attempted to reproduce in the laboratory the experimental procedures to the analysis execution, according to the specifications. It was possible to determine that none of the evaluated samples are in strict conformity with the current technical standards, what reflects the real situation of the products available on the market.

Análise das LER/DORT notificadas no Rio Grande do Norte de 2010 a 2014

The increasing prevalence of Repetitive Strain Injury / Work-Related Musculoskeletal Disorders (RSI / MSDs) has been explained by changes in the work that has been characterized by setting goals and productivity. This fact does not take into account the psycho-physiological characteristics of workers who become ill as a result of professional activities engaged in and also the adverse conditions in which his work was done. This study aimed to analyze the RSI / MSDs reported in the state of Rio Grande do Norte, Brazil, 2010-2014 compared to the profile of the population, epidemiological aspects and features of these diseases. It is a descriptive epidemiological cross-sectional study using secondary data obtained in the Notifiable Diseases Information System (SINAN) in May 2015 was used as the area covered by the Rio Grande do Norte. Data were collected regarding the grievances of work-related RSI / MSDs, assigned by the Worker's Health Reference Center (CEREST) of the State Health Department. Data were processed with the help of Microsoft Excel® 2013 and presented in tables in absolute frequency (n) and relative frequency (%). The results showed a total of 403 notifications of RSI / MSDs, where the vast majority 72% (290) was recorded in Natal. Regarding the profile of notified employees, 88.59% (357) have aged between 25 and 54 years, 62.78% (253) were female, and in relation to education, 31.51% (127) had high school complete. The most affected occupations were seamstresses (the clothing industry) with 24.97% (97), followed by masons, construction with 3.23% (13) and cashiers with 2.99% (12). About the work situation, 75.93% (306) had a formal contract, however, were sent to Communications Occupational accidents (CAT) only 67% (270) of the cases. Regarding the signs and symptoms, pain and limitation of movement were the most mentioned respectively with 98.01% (395) and 95.04% (383) of notifications. Notifications, 94.29% (380) showed exposure to repetitive movements in their workplace. The most frequent specific diagnoses were synovitis and tenosynovitis (CID F 65), with 30.02% (121) of notifications, followed by back pain (CID F 54) to 19.35% (78) and shoulder injuries (ICD M 75) with 15.88% (64). They were away from work 81.64% (329) of workers reported with RSI / MSDs. Evolution more prevalent among cases was temporary disability with 75.68% (305). It was concluded that the SINAN is a database of potential to characterize the profile of RSI / MSDs, requiring, however, an improvement in the coverage of records and data quality. In addition, this study reflects the need to implement protection strategies to workers by companies, signaling promotion, prevention and rehabilitation aimed at reducing these injuries and the improvement of occupational health indicators in Rio Grande do Norte.

Magnitude da morbidade relacionada ao trabalho no Rio Grande do Norte

Diseases and disorders related to work sets up an important public health problem in Brazil and worldwide. However, the reality of these diseases still constitutes a gap with regard to its characterization and epidemiological situation, especially in Brazil. In this context, this study aims to analyze the magnitude of morbidity related to work from the injuries and illnesses reported by Health the Diseases Notifiable of Health of the State Public River Health Department worker Reference Center Information System services Grande do Norte from 2007 to 2014. It is ecological study, quantitative cross-sectional study in which the analysis unit of the municipalities of Rio Grande do Norte. Data were collected from the state base of Diseases Notifiable Information System Centre of the Secretariat of State Workers' Health Reference Public Health of Rio Grande do Norte, between March and June 2015, after the approval of the Committee of Ethics in Research of the Federal University of Rio Grande do Norte, Opinion 014/2014. The population was represented by the universe of cases of diseases and disorders related to work that were reported and shut down the system from 2007 to 2014. Data were analyzed using descriptive and inferential statistics, presented in tables, graphs, charts and figures. For this, we used the Microsoft Excel 2007 and SPSS version 20.0. To check the significance level we opted for the application of the chi-square or Fisher tests. We adopted the significance level of p <0.05. Of the 10,161 cases of diseases related to the reported work, the biological work accidents had the highest percentage (52.84%) followed by serious occupational accidents (37.49%). For diseases, the highlights were musculoskeletal (4.82%), mental disorders (2.19%) and exogenous intoxication (1.97%). Among men, there was a predominance of major accidents (91.80%), mental disorders (70.00%) and exogenous poisoning (52.84%). Women were most affected by biological accidents (77.50%) and musculoskeletal diseases (64.10%). Among workers who have suffered injuries predominated mulatto (%), mean age of 35.86 years, low education (%) and workers in the formal sector (%). Among the accidents, biological (n = 5,369) accounted for 52.84% of cases occurred predominantly among nursing professionals (48.31%). The percutaneous exposure was the most frequent (73.05%) and the occurrence of circumstances was improper disposal of sharps (45.28%), the needle the most common agent (66.62%) and the organic material was blood (72.99%). Most injured workers were vaccinated against hepatitis B (68.13%), but no information as to the assessment of the vaccine response. In the course of the disease predominated ignored the situation with loss of monitoring of clinical follow-up (55.62%). There was also an increase in the notification of serious industrial accidents predominantly male (91.80%) workers aged 25-44 years (54.3%) and typical accidents (76.3%). The temporary disability was the most common outcome (55.53%) and hand the most affected part (33.00%); the mining and construction industry had the highest number of cases (25.1%) in registered employee (34.2%). The findings of this study show a positive result in relation to increased mandatory reporting of injuries and illnesses related to work together to health services that meet victimized workers, towards the occurrence of knowledge of these accidents for decision making in public plans and policies of health. However, the information system still needs improvement in both the coverage and the quality of the data to demonstrate with greater reliability the magnitude of events to support the planning of workers' health into shares in the state.

Ajustes de coeficientes integrantes de processos físicos e bioquímicos na autedepuração em curso de água de médio porte

The mathematical modeling in the simulation of self-purification capacity in lotic environment is an important tool in the planning and management of hydric resources in hydrographic basin scale. It satisfactorily deals with the self-purification process when the coefficients of physical and biochemical processes are calibrated from monitorated water quality data, which was the main focus of this study. The present study was conducted to simulate the behavior of the parameters OD, BOD5, total phosphorus, E. coli, ammonia, nitrite, nitrate and the total metals cadmium, chromium, copper, lead and zinc in the Uberabinha’s lower course (with an approximate annual growth flow between 4-35 m3/s), in a stretch of 19 km downstream of the treated effluent release by the WWTP of the city. The modelings, on the present study, show the importance of constant water quality parameters monitoration over the water course, based on the comparison of the simulations from calibrated coefficients and coefficients obtained in the literature for the period of June until November 2015. After coefficients calibration, there were good adjustments between simulated and measured data for the parameters OD, BOD, Ptotal, ammonia and nitrate and unsatisfactory adjust for the parameters nitrite and E. coli. About the total metals, the adjustments were not satisfactory on the reservoir’s vicinity of the Small Hydropower Plant Martins, due the considerable increase of the bottom sediment in lentic region. The greatest scientific contribution of this study was to calibrate the decay coefficient K and the quantification of the release by the fund S of total metals in watercourse midsize WWTP pollutant load receptor, justified by the lack of studies in the literature about the subject. For the metals cadmium, chromium, copper, lead and zinc, the borderline for K and S calibrated were: 0.0 to 13.0 day-1 and 0.0 to 1.7 g/m3.day; 0.0 to 0.9 day-1 and 0.0 to 7.3 g/m3.day; 0.0 to 25.0 day-1 and 0.0 to 1.8 g/m3.day; 0.0 to 7.0 day-1 and 0.0 to 40.3 g/m3.day; 0.0 to 30.0 day-1 and 0.0 to 70.1 g/m3.day.

Análise da qualidade das águas, Ribeira Brava

O planeamento e gestão dos recursos hídricos é nos dias de hoje uma tarefa complicada, mas interessante e necessária, tendo em vista a satisfação de cada vez mais exigentes padrões de vida das populações e da qualidade do ambiente. Para que sejam possíveis escolhas e decisões judiciosas sobre a melhor forma de utilizar a água disponível, a sua gestão deve ser enformada por leis, actuações administrativas e disposições económico-financeiras, as quais determinam a necessidade da existência de sistemas institucionais competentes para as implementar. Sob o paradigma da sustentabilidade no contexto dos recursos hídricos, procedeu-se a uma avaliação do estado qualitativo das águas superficiais e subterrâneas do concelho da Ribeira Brava, quer a nível da distribuição de águas quer a nível das águas residuais. Inicialmente, caracterizou-se a região hidrográfica em estudo quanto aos aspetos geográficos, demográficos, socioeconómicos, bem como uma perspetiva quanto à caracterização hidrológica e geomorfológica da bacia hidrográfica a ser monitorizada. Posteriormente, apresentou-se, sob um manto teórico, o funcionamento de todo o sistema de abastecimento de água desde a captação até à sua devolução à natureza, passando pelas ETA, redes de distribuição e ETAR, passando a descrever-se a realidade em termos de infraestruturas existentes no concelho da Ribeira Brava. De seguida, procedeu-se à análise paramétrica temporal nas ETA e ETAR do concelho, cruzando esses dados com a legislação em vigor. Como etapa final, retratam-se as principais ilações quanto à monitorização efetuada, quer a nível de águas de distribuição, quer a nível das águas residuais, bem como se contribui com algumas recomendações, tendo em conta a manutenção e melhoria quantitativa e qualitativa da água no concelho da Ribeira Brava.

A Ouvidoria Pública como instrumento de controle das ações da Secretaria de Saúde do Pará

The State and Public Administration have gone through several reforms in search of a quick operation and the provision of services with quality. With the democratization of the country and the issue of the Constitution in 1988, further reform of the State and Public Administration, joined the government agenda in 1995 and included among its objectives, the principles of participation and social control. In view of this, it raises the Public Ombudsman in order to be a channel for the participation of users in the management of public affairs, social control, transparency of administrative actions, improving the quality of service and meeting the needs of the community. The aim of this study is to assess whether the Ombudsman of the State Department of Public Health to contribute to the period 2006-2008, for the improvement of specialized consulting services. The research is characterized as descriptive, qualitative approach. The collection technique used was the interview, conducted with 37 service users and two servants of the Ombudsman. The analysis was developed based on the perception of users and servers in the opinion of the Ombudsman. The most relevant results of the research showed that 41% of users search the Ombudsman because they believed that solve the problem presented. However, even with this level of public acceptance, the Ombudsman reached average index of resolvability of 53% in the period. In his role has not developed mechanisms for quality control of services, which is mentioned by 67% of users. It turned out the same fact in relation to popular participation, which is confirmed by 84% of users. For 24% of users, the problems raised were resolved, and of these, 56% believe that the Ombudsman has contributed to the positive outcome. As a result of the search results, it appears that the Ombudsman's SESPA / PA, is not fulfilling its role to ensuring the democratization of articipation in management, social control and has limited contribution to solving the problems of users and to improve the quality of services

Avaliação de alguns parâmetros da qualidade da anchoita (Engraulis anchoita) enlatada em óleo de girassol e em molho de tomate

O consumo de pescado no Brasil cresceu 40% nos últimos 7 anos passando de 6,46 para 9,03 kg/habitante/ano, valor que se aproxima do recomendado pela Organização Mundial de Saúde. A razão está relacionada com a subutilização de determinadas espécies e a falta de diversificação da indústria processadora para a produção de alimentos com maior valor agregado. Considerando o esgotamento de determinadas espécies com a utilização da sobrepesca, é possível o emprego da anchoita na forma de conservas através da utilização de meios de cobertura como molho de tomate e óleo comestível. Este trabalho teve como objetivo elaborar conservas de anchoita (Engraulis anchoita) com a utilização de 2 meios de cobertura: molho de tomate e óleo de girassol, submetidas a tempos de salmouragem diferenciados, 2 e 5 min e com o emprego ou não de pré-cozimento. De acordo com os padrões estabelecidos, as amostras de pescado fresco utilizadas para a execução dos enlatados apresentaram resultados físico químicos adequados comprovando o frescor do pescado envolvido no processo, ou sejam: 16,29 mg/100 g amostra para N-BVT, 7,90 mg/100 g amostra para N-TMA e pH 6,5. As conservas em molho de tomate submetidas a operação de salmouragem durante 2 min, com e sem pré-cozimento apresentaram, respectivamente, 16,57 e 16,24% proteínas, 3,94 e 4,66% lipídios, 73,0 e 73,28% umidade, 3,22 e 3,67% cinzas, 0,17 e 0,19% de cloretos (NaCl). As conservas com molho de tomate, utilizando anchoita eviscerada salmourada por 5 min, com e sem pré-cozimento, apresentaram respectivamente, 15,94 e 15,31% proteínas, 3,15 e 4,90 lipídios%, 73,70 e 73,98% umidade, 3,80 e 4,10% cinzas, 0,21 e 0,24% cloretos (NaCl). Para as conservas de anchoita em óleo de girassol, utilizando tempo de salmouragem de 2 min, com e sem pré-cozimento, apresentaram 16,97 e 16,76% proteínas, 7,68 e 5,70% lipídios, 65,87 e 68,74% umidade, 3,16 e 3,28% cinzas, 0,10 e 0,12% cloretos (NaCl), respectivamente. As conservas utilizando o pescado previamente submetido a salmouragem por 5 min e posteriormente enlatado com a adição de óleo de girassol, com e sem pré-cozimento apresentaram respectivamente, 15,97 e 15,89% proteínas, 7,91 e 5,19% lipídios, 66,26 e 68,23% umidade, 3,78 e 3,87% cinzas, 0,13 e 0,21% NaCl. As análises microbiológicas das conservas submetidas aos diferentes tratamentos mostraram ausência de Salmonella spp, Staphylococcus coagulase positiva e Clostridium sulfito-redutor, resultados estes, de acordo com o estabelecido pela legislação higiênico-sanitária brasileira. Nos testes de esterilidade comercial não foram constatadas alterações visíveis nos enlatados submetidos a incubação por 5 dias a 36 ± 1°C (determinação de micro-organismos aeróbios viáveis) e a 7-10 dias a 55 ± 1°C (termófilos). Considerando as quantidades de pescado enlatado (80, 90 e 100g), o rendimento para todas as amostras apresentaram, no mínimo, 50% de pescado em relação ao peso líquido. A avaliação sensorial realizada por teste de ordenação para a avaliação da preferência não apresentou diferenças significativas entre as amostras.
