2. Radionuclídeos como marcadores de um novo tempo: o Antropoceno
On May 2019, the members of the Anthropocene Working Group completed a binding vote to affirm some of the key questions that have been agreed in 2016: the Anthropocene should be considered as a formal chronostratigraphic unit, defined by a Global Boundary Stratotype Section and Point (GSSP), using one of the stratigraphic signals around the mid-twentieth cen

3. INVENTÁRIO DO SAPATEIRO DAMIÃO SIMÕES: UM ESTUDO FÍSICO-QUÍMICO DO DOCUMENTO MAIS ANTIGO DO ESTADO DE SÃO PAULO
The oldest manuscript from the Arquivo Público do Estado de São Paulo dating back to the XVI century, which was laminated some decades ago, was analyzed by Raman and FTIR spectroscopies. A book from the XVIII century and Japanese papers were also investigated for comparison purpose. Raman microscopy is a well-known technique, which offers a non-destructive

4. PONTO DE INTERROGAÇÃO: PSEUDÔNIMO DESCONHECIDO E TEXTO INÉDITO DE MACHADO DE ASSIS
Resumo Ao longo de sua vida literária, Machado de Assis utilizou muitas e variadas formas para assinar seus textos. Aqui, incluímos um pseudônimo até então desconhecido no conjunto de assinaturas do escritor. Trata-se de um ponto de interrogação ("?"), sinal com o qual subscreveu um texto esquecido nas folhas do Correio da Tarde e ainda inédito, que

5. Salinity and stable oxygen isotope relationship in the Southwestern Atlantic: constraints to paleoclimate reconstructions
Abstract: Stable isotopes have been widely used in the literature both to discuss current ocean circulation processes, as well as to reconstitute paleoceanographic parameters. The distribution of oxygen and deuterium stable isotopes in seawater (δ18Osw and δDsw) at the Western Tropical South Atlantic border was investigated to better understand the main fr

7. Changes in trophic characteristics of two fish species of Astyanax (Teleostei: Characidae) in response to aquatic pollution
ABSTRACT The trophic plasticity of most fish species of Astyanax Baird & Girard, 1854 in response to environmental changes and resource availability is high. This work evaluates the differences in the trophic characteristics of two congeneric species, Astyanax taeniatus (Jenyns, 1842) and Astyanax lacustris (Lütken, 1875), in Rio das Velhas Basin, which is

8. NEAR INFRARED SPECTROSCOPY: RAPID AND ACCURATE ANALYTICAL TOOL FOR PREDICTION OF NON-STRUCTURAL CARBOHYDRATES IN WOOD
ABSTRACT The non-structural carbon reserves in the various organs of trees are associated with their growth and the mechanism of resilience when exposed to environmental stresses, especially the water deficit. The goal of this study was to develop multivariate models to estimate the amount of non-structural carbohydrates (starch, sucrose, reducing sugars, to

9. The Barreiro suite in the central Ribeira Belt (SE-Brazil): a late Tonian tholeiitic intraplate magmatic event in the distal passive margin of the São Francisco Paleocontinent
Abstract New geochemical, U-Pb, Lu-Hf and Sr-Nd data from the Barreiro Suite metabasites in comparison with enclaves within the distal Andrelândia Group and the orthogranulites of the Juiz de Fora Complex are presented. Geochemical data suggest intraplate setting, with high and low-TiO 2 , TDM Nd ages between 1.80 and 1.41 Ga, negative ΕNd t and ( 87 Sr/ 8

10. Lack of quadruple and quintuple mutant alleles associated with sulfadoxine-pyrimethamine resistance in Plasmodium vivax isolates from Brazilian endemic areas
BACKGROUND AND OBJECTIVE Brazil is responsible for a large number of Plasmodium vivax cases in America. Given the emergence of P. vivax parasites resistant to chloroquine and the effectiveness of antifolates in vivax malaria treatment together with a correlation between mutations in P. vivax dhfr and dhps genes and SP treatment failure, the point mutations

11. Geochemical signatures and weathering rates in soils derived from different granites in contrasting climatic locations
ABSTRACT. We studied the mineralogical properties and chemical composition of different granites using energy dispersive X-ray spectroscopy coupled with scanning electron microscopy to understand the relationship between granite signatures and soil characteristics, including weathering patterns and soil fertility status. The discriminant analysis (DA) was ba

12. Signatures of Selection From Candidate Gene Polymorphisms Panel in Five Zebu Breeds
ABSTRACT The signals of selection using candidate genes polymorphism were studied in five zebu breeds of Mexico. Three loci from GHRH and complementarily Steroyl Co Desaturase F762, Dopamine Beta Hydroxilase 17299, and LEP3272 were identified under selection. Findings depict Zebu selection pressure mainly on Brahman breed resulting in a divergent structure p
