The activities carried out in the region range from the manufacturing process to the processing of jeans, which is carried out in industrial laundries. As with any industrial procedure, laundries are major generators of waste, with textile sludge being one of the main ones, generated in large volumes. It is a potential pollutant capable of compromising soil, water and air quality, directly affecting the health and well-being of the population. On the other hand, the construction industry continues to be one of the biggest consumers of natural resources, mainly through the use of sand to make concrete and mortar. This research studied the incorporation of jeans laundry sludge, at levels of 10%, 20% and 25%, into mortar mixes for coatings, with the aim of providing a more sustainable destination for the sludge, as well as serving as an alternative raw material. The research aimed to study the mechanical behavior of modified mortars in order to evaluate their physical and mechanical properties after partially incorporating the waste in relation to the fine aggregate (sand). Tests were carried out on the particle size composition, unit mass and specific mass of the waste, as well as the characterization of the textile sludge. As the waste partially replaced the fine aggregate, the same tests were carried out on the sand. Although the sand and sludge had different particle size curves, both were within the usable zone for fine aggregate. Sludge had a unit mass 45% lower than that of sand. The specific mass of silt was also lower than that of sand, totaling 1.62 g/cm³ and 2.63 g/cm³, respectively. When evaluating the mechanical strength of the specimens, there was little variation between the different mixes, but the mortar with 10% sludge incorporation had the highest compressive strength and flexural tensile strength when compared to the others. In the water absorption and capillarity coefficient results, the residue was able to effectively fill the small pores in the mixture. Finally, it was possible to classify the mortars studied, which achieved minimum values for the characteristics of compressive strength, flexural tensile strength and capillarity coefficient, receiving the designation P3, R1, C1 in the four types.Item Sustentabilidade hídrica e desenvolvimento regional: o papel das barragens subterrâneas no semiárido brasileiro(2024-10-04) Melo, Giovana Elvira de; Freire, Maria Betânia Galvão dos Santos; http://lattes.cnpq.br/2636653493262436; http://lattes.cnpq.br/2684222726881637Regional development in areas like the Brazilian Semi-arid region is intrinsically linked to water sustainability. Water scarcity not only limits economic growth but also negatively impacts public health and exacerbates social inequalities. In this context, the implementation of sustainable water resource management strategies, such as the construction of underground dams and the adoption of agricultural practices adapted to local climatic conditions, becomes essential to promote sustainable socioeconomic development in these regions. Underground dams, in particular, stand out as a water resource management tool and as an alternative, low-cost technology for construction and maintenance, being a hydro-environmental work that aims to meet water demands for human, animal, and agricultural consumption, especially in arid and semi-arid regions. They interrupt the flow of surface and groundwater through an impermeable wall built transversally to the direction of the water flow. Rainwater infiltrates slowly, forming or raising the water table, which will later be used by plants. In the face of the challenges imposed by prolonged drought and the economic vulnerability of rural communities, the importance of intensifying rainwater harvesting and storage becomes evident, not only as a measure to mitigate crop losses but also as a mechanism to significantly increase the income of rural communities and promote sustainable economic development in the region. Strengthening these practices, combined with public policies aimed at the Brazilian Semi-arid region, can transform the reality of the region, making it more resilient to climatic adversities, promoting water security, and contributing to the reduction of regional inequalities. In this sense, the main objective of this work is to review the literature on the role of underground dams in promoting water sustainability and regional development in the Brazilian Semi-arid region, covering the advances, limitations, and opportunities of this technology in the context of water resource management.Item Atualização da Coleção de Solos de Referência de Pernambuco e produção de materiais didáticos para o ensino e a popularização da ciência do solo(2024) Luiz, Maria Eloyse Gonçalves; Araújo, Paula Renata Muniz; http://lattes.cnpq.br/1779598476646308; http://lattes.cnpq.br/9000206461335481Item Estágio em recursos hídricos: sistema de drenagem superficial em pilhas de rejeito(2024) Costa, Maria Vitória Gomes da; Montenegro, Abelardo Antônio de Assunção; http://lattes.cnpq.br/7947714302950574; http://lattes.cnpq.br/8775749630925927Item Acúmulo e exportação de macronutrientes primários no feijão-caupi fertirrigado por gotejamento contínuo e pulsado(2024-08-14) Costa, Maria Vitória Gomes da; Silva, Gerônimo Ferreira da; http://lattes.cnpq.br/4596017290307351; http://lattes.cnpq.br/8775749630925927Item Diagnóstico geoambiental em áreas costeiras(2020) Silva, Davi Francisco da; Rolim Neto, Fernando Cartaxo; http://lattes.cnpq.br/3213540942171312; http://lattes.cnpq.br/1369118748875327Item Avaliação da vazão de pontas de pulverização hidráulica de jato cônico vazio(2024-03-01) Souza, Deyziane Carla França de; Dadalto, Juliana Pinheiro; http://lattes.cnpq.br/9710570380222413; http://lattes.cnpq.br/4094528454475078In the search for uniform distribution in the application of plant protection products, the choice and monitoring of spray tips plays an indispensable role in terms of treatment effectiveness and operational efficiency. The aim of this study was to evaluate the flow uniformity and spray distribution profile of three sets of Teejet empty conical jet nozzles with different nominal flow rates. The nozzles have polypropylene bodies and ceramic inserts and were subjected to the spacing, pressure and working speed parameters that are commonly used in daily operations. Measurement was carried out using a digital flow meter, which took unit readings of each tip over a period of 5 seconds. For the TXA8001VK nozzle set, 9 irregular nozzles were found, corresponding to 12% of the spray area; for the TXA8003VK set, 19 irregular nozzles were identified, corresponding to 26% of the spray area; and finally, for the TXA80015 set, 22 irregular nozzles were found, corresponding to 30% of the spray area. The irregular tips were responsible for causing a variation of +1.8%, -5.67% and -3.13% in the application rate, respectively. The TXA8001VK and TXA80015 set of tips had lower standard deviations and coefficients of variation, indicating greater uniformity when compared to the TXA8003VK set, which had a lower standard deviation.Item Monitoramento da temperatura e umidade em silo piloto utilizando o arduino uno como microcontrolador(2022) Souza, Adielly Mayara de; Laurenti, Renato; http://lattes.cnpq.br/8853216777317634; http://lattes.cnpq.br/9464238290133642
