Item A Sílica Livre Cristalizada e as Condições de Trabalho em Santarém-PA(Universidade Federal do Pará, 2015) CAVALCANTE, Clarissa Maciel; POMPEU NETO, Bernardo BorgesSilica (SiO₂) is one of the most abundant elements in the Earth's crust, and in its crystalline form, it is toxic to humans, potentially causing silicosis and even cancer with prolonged exposure. This study investigates working conditions in marble workshops in Santarém-PA and the risks of exposure to crystalline silica. The research involved visits to four companies in the sector, using the Ministry of Labor and Employment’s Reference Manual for Marble Workshops as an evaluation tool. The results indicate a lack of worker training and misinformation about occupational hazards. Collective protection measures, such as wet-cutting machines, are adopted but not strictly enforced. Personal protective equipment is provided but not consistently used. The study concludes that exposure to free crystalline silica in the region’s marble workshops is high and poses a significant health risk to workers. It emphasizes the need for surveillance actions and further investigations to improve working conditions and worker health protection.Item CONCRETOS FABRICADOS COM AGREGADOS GRAÚDOS DISPONÍVEIS EM SANTARÉM E REGIÃO OESTE DO PARÁ(Universidade Federal do Pará, 2015) MAIA, Carlos Tadeu Arantes; SOUZA, Paulo Sérgio LimaThe study examines structural concrete production using different coarse aggregates available in Santarém, analyzing fresh and hardened state properties. Gravel, pebble, and quebradinho were tested with three water/cement ratios (0.74, 0.54, and 0.41). Results showed lower water consumption with pebble and higher final strengths with gravel. A cost analysis highlighted the economic advantage of quebradinho for 20 and 30 MPa concretes. Findings support the feasibility of using local aggregates in concrete production.Item ZONEAMENTO DE RUÍDO: PROPOSTA DE CURVAS DE RUÍDO APLICADAS AO AEROPORTO INTERNACIONAL DE MANAUS/EDUARDO GOMES(Universidade Federal do Pará, 2014) NASCIMENTO, Clive Reis do; MENDES, Ronaldo Lopes Rodrigues; OLIVEIRA, Dênio Ramam Carvalho deNoise pollution is an environmental issue that can significantly impact the population’s quality of life. Aircraft noise, generated by engines and aerodynamics, can be mapped through noise curves and used for the development of a Noise Zoning Plan (NZP). With the publication of RBAC No. 161, the NZP of Manaus/Eduardo Gomes International Airport became obsolete. This study used operational airport data and the INM software to generate new noise curves at levels of 85, 80, 75, 70, and 65 dB(A). Compared to previous curves, the new ones cover a 43.58% larger area and a 193% larger population, including four additional schools. Municipal legislation does not cover all affected areas, suggesting the need for adjustments to comply with RBAC No. 161 requirements.Item AVALIAÇÃO DA CAPACIDADE DE CARGA GEOTÉCNICA E RECALQUE DE ESTACAS HÉLICE CONTÍNUA MONITORADA EM UM EDIFÍCIO DE RIO BRANCO – AC(Universidade Federal do Pará, 2013) DAMASCENO, Davi Luiz Gruhn; ANJOS, Gérson Jacques Miranda dosThis dissertation evaluates the geotechnical load capacity and settlement of Continuous Flight Auger (CFA) piles used in the construction of the Federal Police Superintendency (DPF/AC) in Rio Branco, Acre. The building comprises three blocks separated by expansion joints, featuring a basement, four floors, an engine room, and a heliport. The foundations include isolated footings and CFA piles, with the latter being the focus of this study. Using soil stratigraphy and NSPT data from SPT boreholes, a computational program was employed to assess the geotechnical load capacity of the piles using various methodologies, including Aoki & Velloso (1975), Monteiro (1997), Kárez & Rocha (2000), Antunes & Cabral (1996), Gotlieb et al. (2000), and Décourt & Quaresma (1978/1996). Settlements were estimated using the Pile Settlement Calculation (Module 15) software, which applies Aoki & Lopes’s (1975) method. Results showed a wide variation between the methods analyzed, leading to pile depths lower than those in the original design. The estimated settlements ranged from 1 to 8 mm, and the angular distortion between contiguous piles did not compromise the building’s functionality.Item TÉCNICAS DE REFORÇO ESTRUTURAL PARA EDIFICAÇÕES ANTIGAS. ESTUDO DE CASO NA CIDADE DE RIO BRANCO – ACRE(Universidade Federal do Pará, 2013) AMORIM, Denis Cley de Souza; OLIVEIRA, Dênio Ramam Carvalho deThis study aims to demonstrate the design and calculation verification based on NBR 6118 (ABNT, 2007) for reinforced concrete columns, focusing on structural reinforcement techniques for old buildings. Methods such as concrete jacketing, steel profiles, steel plate bonding, and carbon fiber-reinforced polymers (CFRP) were identified and analyzed. The case study of the revitalization of a historic building in Rio Branco - Acre demonstrated that the applied reinforcement technique increased the load-bearing capacity of the strengthened columns.Item ESTUDO DE CASO DO ABASTECIMENTO D’ÁGUA DO MUNICÍPIO DE SANTARÉM NO PARÁ(Universidade Federal do Pará, 2015) ANDRADE, Elen Conceição Leal de; MENDES, Ronaldo Lopes RodriguesThis work addresses the water supply in the municipality of Santarém, Pará, and the various factors that directly affect the population's use of this resource. The main objective was to assess water usage in the supply sector, quantifying and qualifying its various forms to contribute to sustainability indicators. Currently, the municipality is supplied by the Pará Sanitation Company (COSANPA) and the Municipal Supply Secretariat (SEMAB). The research was conducted in three stages: literature review, field survey, and result analysis. Findings indicated that most of the population does not waste water, although the absence of water meters makes accurate consumption measurement difficult. Water quality was rated as average by 21.57% of respondents, while 33% reported frequent water shortages, leading part of the population to rely on private wells. The study concludes that understanding these findings can contribute to future projects aimed at improving water supply in the municipality.
