In this study, the impact of the PhyloCode on scientific literature was analyzed from its first appearance in the literature to 2021. We investigated the areas that have most assimilated the proposal, the criticisms that have arisen over time, and whether there has been growing adherence to it up to the present day. The analyzed data were obtained from the Clarivate Analytics Web of Science database, where 121 articles that used or discussed the PhyloCode were found. Initially, there was an increase in publications, but in mid-2004, there was a downward trend, which was more noticeable after 2008. Results suggest that despite the criticisms, the proposal has been used in research in several areas, mainly in Zoology and Botany, as an alternative to the Linnaean ranking system. Most articles have been published in Systematics and Taxonomy and discuss the functionality of the proposed code. Despite the proposal's potential, its acceptance can be considered relatively low and it still generates discussions, just like any scientific novelty.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"96 suppl 3","pages":"e20231178"},"PeriodicalIF":1.1,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142738106","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}

New schemes were developed to form the basis of the local approximation subspace, which were derived by approximating only the k 2 u term of the Helmholtz equation. The construction of a basis of the local approximation subspace allows the new approach to be able to represent any finite difference scheme that belongs to this subspace. The new method is both consistent and capable of minimizing the dispersion relation for all stencils in all dimensions. In the one-dimensional case and 3-point stencil, pollution error is eliminated. In the two-dimensional (2D) case and 5-point stencil, the Complete Centered Finite Difference Method presents a dispersion relation equivalent to Galerkin/Least-Squares Finite Element Method. In the 2D case and 9-point stencil, two versions were developed using two different bases for the local approximation space. Both versions are equivalent and exhibit a dispersion relation similar to Quasi Stabilized Finite Element Method. Additionally, the dispersion analysis revealed a connection between the coefficients of the linear system and the stencil symmetry.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"96 4","pages":"e20240522"},"PeriodicalIF":1.1,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142738088","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 study measured variables related to the dry matter intake (DMI) and bromatological fractions of diets, as well as performance of steers. No significant differences were observed between treatments in terms of DMI during the experimental period. Although DMI intake was similar across treatments, steers receiving the mixed diet exhibited significantly higher weight gain than those on the soybean hull diet (1.300 vs. 0.972 kg day-1). However, both these treatments showed comparable results to the white oat grain diet (1.203 kg day-1), achieving a similar final weight (387.22 kg).

Thus, the soil fertility management is important for suitable use of Cerrado's soils. After 40 years of increasing use of Cerrado for agricultural purposes, this work aimed to evaluate the soil fertility of a representative area known as Triângulo Mineiro and Alto Paranaíba (TMAP) mesoregion. Different land uses from 126 farms were selected for soil sampling and assessed the following properties: pH; exchangeable Al3+, Ca2+, Mg2+; available P, K+, S, B, Fe, Cu, Mn, and Zn; soil organic matter (SOM); and cation exchange capacity (CEC) effective and potential at pH 7.0. Land uses improved the soil fertility properties compared to native Cerrado vegetation, except planted forests. The pH increased and Al3+ was neutralized, however, satisfactory contents of Ca2+ and Mg2+ were not reached. CEC is still considered low to medium, since SOM was not significantly increased. Available P, S, Fe, Mn, Zn, and Cu contents increased, being considered satisfactory. In general, our findings suggest that the nutrients can be considered adequate for crop production and sustainability. However, continuous monitoring for maintenance of soil fertility and adoption of best management practices are needed.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"96 4","pages":"e20240116"},"PeriodicalIF":1.1,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142738091","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}

Thus, this study aimed to identify and discuss factors that can influence the implementation of ecological corridors designed from a multicriteria analysis. For this purpose, the ecological corridor implementation efforts of a Non-Governmental Organization (NGO) in an Atlantic Forest region were evaluated. The following information about the restoration projects was collected from the NGO database: georeferenced restoration polygons, restoration technique, project size, motivation, and land use tenure characteristics of the restoration site. Restoration polygons were spatially referenced to the planned corridor areas and classified according to land use and land cover, slope, distance to roads and occurrence in Permanent Preservation Areas. The NGO implemented 455.0 hectares of restoration, with only 10.7% within proposed corridors. NGO projects were concentrated on ecological restoration, which presents significant differences between ecological corridors. In practice, the implementation of restoration areas was primarily guided by the local characteristics of the landscape, project's constraints and the will and interest of rural landowners in restoring their properties. This differs from its planning, in which social and economic aspects were not considered and only the environmental variables were taken into.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"96 suppl 3","pages":"e20230768"},"PeriodicalIF":1.1,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142738123","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}

They showed significant antioxidant activity and inhibited AChE; the cytotoxicity observed to the human breast cancer cells MCF-7 and MDA-MB-231 were higher than in normal cell line MCF-10A. ADS04 was 7.62 times more cytotoxic to MCF-7, and ADS14 was 2.03 times more cytotoxic to MDA-MB-231 than to MCF-10A. The extracts showed similar cytotoxicity between PC-3, a human prostate cancer cell line, and MCF-10A.
