A total of 40 bacteria and 24 fungi were evaluated. Eleven bacteria (27.5%) produced protease, 13 (32.5%) amylase activities. Nine (37.5%) fungi produced cellulase, lipase, and ligninase.

The primary aim is to enhance fracture classification accuracy by integrating the k-means algorithm with a genetic algorithm to cluster joints and faults. The study employs a combination of traditional field methods, library research, and advanced mathematical techniques, including digital elevation models and satellite imagery, to identify and classify fractures. The analysis reveals two main fracture trends: one oriented N20E, parallel to the anticline axis, and the other N80W, perpendicular to the axis. These trends are consistent with regional tectonic forces, specifically the structural characteristics of the Zagros orogenic belt. Additionally, shear-tensile joints are identified, reflecting the impact of local faulting activities on fracture formation. The results demonstrate that the combined use of k-means and genetic algorithms offers significant advantages over traditional fracture analysis methods, particularly in terms of improving clustering accuracy and reducing errors associated with complex geological settings. This approach highlights the importance of integrating advanced mathematical techniques in geological studies, contributing valuable insights to the petroleum industry and enhancing the understanding of fracture systems in structurally complex environments.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"97 3","pages":"e20250043"},"PeriodicalIF":1.1,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extreme values for rainfall and flow were identified using the 99th percentile and the Gumbel distribution, respectively. The Mann-Kendall test analyzed trends in extreme events and historical time series. Results indicated that extreme events were mostly not statistically significant. However, the historical series showed a balance of positive and negative trends in precipitation, while all flow trends were negative. A spatial distribution map of accumulated rainfall averages was created using the Climate Hazards Group Infrared Precipitation with Stations (CHIRPS) platform, revealing spatial rainfall heterogeneity across the basin. Additionally, a double-mass graph from CHIRPS data compared changes within sub-basins to the basin's average.

Therefore, it is necessary to understand the soils, including those with permafrost, as well as the relief and the occurrence of organic carbon at Byers Peninsula. This study aims therefore to investigate soil physical and chemical properties at Byers Peninsula, Maritime Antarctica, in particular, the distribution of organic carbon. Thirteen soil profiles were described, collected, and subjected to a physical, chemical, and spatial analysis. Colonization by avifauna and vegetation is important for inputing soil organic carbon at Byers Peninsula. Cryoturbation and permafrost are crucial for the redistribution of the C pool. Distribution of organic carbon on the Byers Peninsula have shown that its concentrations are higher and more punctual at the surface, but also that carbon has been redistributed to deeper layers. Gelisols (Cryosols) are important C pools. They are extremely useful from the environmental monitoring perspective as they represent areas sensitive to temperature increases on the Antarctic Peninsula caused by global climate changes. Using geomorphological groups is one way to improve the understanding of these relief forms, soil and rock types, vegetation patterns, and the presence of permafrost.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"97 3","pages":"e20240310"},"PeriodicalIF":1.1,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aims to evaluate the development of new materials based on post-consumer polyethylene with the addition of different content of PET fibers (0, 5, 10, and 15 wt.%) processed by fusion in a twin-screw extruder with a side feeder. The processing conditions were set so that the polyester remained in the fiber shape in the melt bulk. In a second step of the study, a compatibilizer agent (polyethylene grafted maleic anhydride-PE-g-MA) was added in the PE/PET fiber blends to evaluate the improvement in the interaction between phases. Mechanical, rheological, and morphological analyses were carried out and showed that PE/PET fiber blends are promising structured materials to be used for the development of new materials with different properties.
