The pandemic caused by COVID-19 meant, in many countries, the establishment of a period of confinement in which families were forced to restrict movement and social contacts with the consequent risk of inactivity. Our objective as to analyze the degree of psychosocial well-being, sociodemographic aspects and use of technological means depending on the educational level of the parents. The sample consisted of 2316 children aged between 3 and 12 years (M = 7.70; SD = 2.86). For the analysis and treatment of the data, the statistical software SPSS 25.0 (IBM Corp, Armonk, NY, USA) was used. We found that the European participants used more video consoles (M = 0.89 ± 1.33) and tablets (M = 1.30 ± 0.95), while the Ibero-Americans obtained higher values in the use of TV (M = 2.28 ± 1.10) and levels higher in a negative state of psychosocial well-being (M = 7.29 ± 1.07) and in tiredness/fatigue (M = 4.34 ± 2.44). We concluded that, during the period of confinement in European areas, higher values were obtained in the time dedicated to Physical Activity (PA), use of tablets, school task performance, artistic activities, family games, reading, free play and hours of sleep; while in Ibero-America, there were longer times in the use of technological devices and performing domestic tasks.

The extraction of coal seams with high gas content and low permeability presents significant challenges, particularly due to the extended period required for gas extraction to meet safety standards and the inherently low extraction efficiency. Hydraulic fracturing technology, widely employed in the permeability enhancement of soft and low-permeability coal seams, serves as a key intervention. This study focuses on the high-rank raw coal from the No.

Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide ( ), owing to its effect on cerebral blood flow, tissue , tissue proton concentration, cerebral metabolism and cognitive and neuronal function. In normal environments and in the absence of pathology, at least over acute time frames, hypercapnia is usually managed readily via the respiratory chemoreflex arcs and/or acid-base buffering capacity, such that there is minimal impact on cerebrovascular and neurological function. However, in non-normal environments, such as enclosed spaces, or with pathology, extended exposures to elevations in can be detrimental to cerebral health.

High-entropy metal-organic frameworks (HE-MOFs) hold promise as versatile materials, yet current rare examples are confined to low-valence elements in the fourth period, constraining their design and optimization for diverse applications. Here, a novel high-entropy, defect-rich and small-sized (32 nm) UiO-66 (ZrHfCeSnTi HE-UiO-66) has been synthesized for the first time, leveraging increased configurational entropy to achieve high tolerance to doping with diverse metal ions. The lattice distortion of HE-UiO-66 induces high exposure of metal nodes to create coordination unsaturated metal sites with a concentration of 322.

Purpose: Diffusing alpha-emitters Radiation Therapy ("Alpha DaRT") is a new cancer treatment modality that employs radium-224-loaded metal sources implanted in solid tumors to disperse alpha-emitting atoms within a therapeutic "kill-zone" of a few millimeters around each source. Preclinical studies have demonstrated tumor growth delay in various cancer types, including glioblastoma multiforme, and the method is used in clinical trials for patients with skin and head and neck cancer. This study aims to assess the safety and feasibility of implementing Alpha DaRT for brain tumor treatment in a large animal model.

Single-atom catalysts (SACs) have been increasingly acknowledged for their performance in sustainable Fenton-like catalysis. However, SACs face a trade-off between activity and stability in peroxymonosulfate (PMS)-based systems. Herein, we design a nano-island encapsulated single cobalt atom (Co-ZnO) catalyst to enhance the activity and stability of PMS activation for contaminant degradation via an "island-sea" synergistic effect.
