Theoretical frameworks suggest that cognitive inhibition suppresses irrelevant information in working memory, preventing overload and promoting the processing of task-relevant information. Consequently, it may also contribute to more complex skills, such as abstract reasoning, by facilitating the retention and processing of patterns and relationships. However, empirical evidence does not consistently show these relationships in early elementary school years.

Article Synopsis
  • Cor Triatriatum Dexter (CTD) is a rare heart defect that splits the right atrium into two chambers, with a milder version called incomplete CTD (CTDi) that only partially divides it.
  • CTDi can be linked to interatrial septal defects and often presents in adults who experience cryptogenic strokes, usually leading to referrals for closure of a patent foramen ovale (PFO).
  • Successful PFO closure in patients with CTDi can be challenging due to complications in visualization and device deployment, making advanced imaging techniques and careful planning essential for positive outcomes.

Article Synopsis
  • * Four hybrid silica xerogels were created using tetraethoxysilane and different organochlorinated triethoxysilane precursors, all maintaining a constant 10% organochlorinated content but varying in the organic group’s structure.
  • * Thermal decomposition analysis identified three distinct pyrolysis events and clarified reaction pathways, showing that these processes are significantly influenced by the type of organic group present.

The synthesis and characterization of a hydrochar/CeO composite along with its evaluation in methylene blue degradation under visible light are presented. The methodology consisted of a single-pass hydrothermal method, having as synthesis conditions 9 h of reaction time, 210 °C, autogenous pressure, and a biomass/CeO ratio of 100:1. The composite characterization revealed good dispersion of CeO in the carbonaceous matrix and significant synergy in the composite activation using visible irradiation.

This work proposes a rigorous mathematical model capable of reproducing the adsorption process in dynamic regime on advanced monoliths geometries. For this, four bed geometries with axisymmetric distribution of channels and similar solid mass were proposed. In each geometry a different distribution of channels was suggested, maintaining constant the bed dimensions of 15 cm high and 5 cm radius.
