Controle de compactação dos solos por meio do frasco de areia com agregado miúdo da região metropolitana de Manaus-AM
(2025-07-21) Maquiné, Aldenei de Lima; Damasceno, Micael Felipe; Feitoza, José Costa
Currently, the sand bottle is used for control soils compaction in most earth works in the Amazonas, relating the apparent specific mass "in situ" with the apparent specific mass dry according to the optimum humidity obtained in the laboratory. This is a geotechnical test using washed, dried and standardized sand in the granulometric range between 0.80 and 0.60 millimeters. This research replaces the sand in the standardized bottle, with fine aggregate from the metropolitan region of Manaus-AM. The granulometry tests indicate that the sand collected from this research is very uniform, well graded and has a maximum characteristic diameter equal to 1.19 mm. The predominant granulometric fraction classifies the particulate material from Manaus as medium sand (56.67%), with apparent dry specific mass and grain mass respectively equal to 1.5118 g/cm³ and 2.6042 g/cm³. Performed the field tests were carried out in the parking lot of the Instituto Federal do Amazonas (IFAM), Manaus Centro Campus, obtaining the apparent specific masses "in situ" with the standard sand bottles equal to 1,727.74 kg/m³ and with fine aggregate from Manaus the value of 1,620.13 kg/m³. The Degree of Compaction was satisfactorily evaluated based on the relative percentage error, with a view to paving in the Amazonas.

(2025-01-28) Nobre, Jaritsa Maria da Costa; Aguiar, Cristiane Pereira de; http://lattes.cnpq.br/8948885803989120; Aguiar, Cristiane Pereira de; http://lattes.cnpq.br/8948885803989120; Fernandes, Francisco José Rodrigues; http://lattes.cnpq.br/3166612623704256; Lucena, Ana Maria Dias da Silva; http://lattes.cnpq.br/3426441277160847
This paper aims to describe the process of regularizing and obtaining a occupancy permit for a single-family social housing property located in the Cidade Nova I neighborhood in the city of Manaus, Amazonas. Urban expansion requires strict control by public organizations, making regularization and issuance of a occupancy permit essential for the proper occupation of spaces and the correct execution of works and engineering services. The Cidade Nova neighborhood, located in the northern part of Manaus, was planned in the 1980s during the government of Professor José Bernardino Lindoso, initially to house 15,000 low-income housing units. However, only 1,800 homes were completed in the first phase, inaugurated on April 23, 1981. Since then, the neighborhood has expanded to include stages I, II, III, IV, and V, becoming the most populous in Manaus. The regularization of properties in Cidade Nova is an ongoing and detailed process that involves the presentation of documents, architectural projects, and obtaining certificates. The Municipal Institute of Urban Planning of Manaus (IMPLURB) considers regularization and occupancy permits essential for issuing the Certificate of Regularization and Occupancy Permit for buildings completed without prior approval and licensing of the architectural project. This study describes the case study of a single-family property that underwent this process, completed in approximately four months, resulting in a 20% increase in value after the issuance of the occupancy permit. During the execution of this work, the stages and challenges faced in the regularization and occupancy permit process were analyzed, with emphasis on the conformity of the building volume with current standards and the absence of frontal setback from the land, as required by Law No. 1.838/2014. The proposed alternatives were also evaluated, such as the applicant's handwritten justification due to socioeconomic limitations, and the CMDU's opinion that verified the possibility of regularizing the property. The results showed that, in addition to legalizing the occupation and use of the space, regularization provides greater security and peace of mind to the owners. The success in obtaining the occupancy permit represents habitability under current legislation and reflects the commitment to sustainable and orderly urban development in the city of Manaus. For future work, we suggest implementing realtime sharing systems between the sectors responsible for analyzing the regularization process, providing guides and teaching manuals, and creating free or low-cost technical and legal assistance programs.
Inteligência Artificial na construção civil: benefícios, desafios e a importância do profissional na tomada de decisão
(2025-03-03) Barboza, Tereza Nazaré Ulloa; Aguiar, Cristiane Pereira de
The research explores the impact of Artificial Intelligence (AI) on decision-making in the construction industry, particularly in the use of programs for the preparation of architectural projects. Although AI offers several opportunities for resource optimization, scenario simulation, and process automation, it also presents challenges, such as the dependence on automated systems that can compromise the quality of technical work. The study seeks to investigate the potential benefits and risks associated with the implementation of AI in the sector, with a focus on the creation and management of architectural projects. The methodology adopted involved bibliographic research based on academic articles, books, and recent case studies, with a thematic analysis: identifying the programs that are classified as AI and how they affect today's civil engineering scenario, their challenges, and benefits. The results indicate that, although AI can improve efficiency and reduce costs, its application without technical supervision can generate misinterpretation and legal problems, especially when users do not have specialized training. The research concludes that, in order to maximize the benefits of AI, it is essential that construction professionals continue to act critically, supervising technological tools and ensuring that projects comply with local standards and requirements. Therefore, AI should be seen as a complementary tool, and not as a substitute for the technical knowledge of professionals in the sector.
Estudo da influência do lítio na síntese de titanato de sódio como uma alternativa para baterias de estado sólido
(2025-01-04) Souza, Handerson Cunha de; Moura, David da Silva; Oliveira Neto, Benjamin Batista de
The growing demand for new energy sources has been a stimulus for extensive research in the area of materials, especially in high-performance solid-state batteries. Recently, sodium trititanate (Na2Ti3O7), an inorganic chemical compound, has received attention due to its effectiveness in ion exchange and catalytic properties. However, its application as an electrolyte in solid-state batteries is limited due to its low electrical conductivity. To overcome this limitation, lithium-doped Na2Ti3O7 nanoparticles were synthesized in different proportions, ranging from 0% to 5% by mass, using the microwave-assisted hydrothermal method. Samples were extensively characterized by XRD, 0%, 1% and 5% samples were also analyzed by DTA, Raman spectroscopy and complex impedance spectroscopy. Notably, the 5% lithium doped sample exhibited an electrical resistance approximately one order of magnitude lower than the undoped material. These promising results highlight the potential of doped sodium titanate as a viable component for high-performance solidstate batteries due to its enhanced structural and conductive properties.
