This article presents a study of the impacts caused by Fundão dam failure in buildings from Gesteira district, Barra Longa city, Brazil. The analyzed dataset was built using technical reports from surveys carried out in 152 buildings. Principal component analysis was capable of explain the interdependence of data variable and allowed conditions of understand the consequences and evidenced pathologies. Heavy vehicle traffic caused more damage (57% of buildings) to the studied buildings than the contact with the tailing mud (43% of buildings).

Maternal Inflammatory Proteins in Pregnancy and Neurodevelopmental Disorders at Age 10 Years.
JAMA Psychiatry

Center for Neuropsychiatric Schizophrenia Research (CNSR& Center for Clinical Intervention and Neuropsychiatric Schizophrenia Research (CINS), Mental Health Centre Glostrup, Copenhagen University Hospital - Mental Health Services CPH, Copenhagen, Denmark.
Importance: Maternal inflammation during pregnancy has been associated with an increased risk of neurodevelopmental disorders (NDDs), such as attention-deficit/hyperactivity disorder (ADHD) and autism, and cognitive deficits in early childhood. However, little is known about the contributions of a wider range of inflammatory proteins to this risk.
Objective: To determine whether maternal inflammatory proteins during pregnancy are associated with the risk of NDDs and executive functions (EF) in middle childhood and to identify protein patterns associated with NDDs and EF.
Quantitative Criteria for Solvent Selection in Liquid-Phase Exfoliation: Balancing Exfoliation and Stabilization Efficiency.
Nanomaterials (Basel)

The selection of solvent is pivotal in liquid-phase exfoliation (LPE), as an ideal solvent minimizes the energy required to disrupt the interlayer attractive interactions while stabilizing exfoliated layers to prevent re-agglomeration. This study theoretically analyzed the LPE of Mg(OH) in different solvents, including water, dimethyl sulfoxide (DMSO), dimethylformamide, N-methyl-2-pyrrolidone (NMP), isopropyl alcohol, and 2-butanone, through first-principles calculations combined with experimental validation. DMSO was identified as the most effective solvent for reducing the interlayer attraction, based on exfoliation energy calculations, while NMP was the most efficient for stabilizing exfoliated layers, based on binding energy assessments.

Background: Outcome measurement is increasingly recognised as a vital element of high-quality service provision, but practice remains variable in the field of intellectual disabilities. The Health of the National Outcome Scales for people with Learning Disabilities (HoNOS-LD) is a widely used Clinician Reported Outcome Measure in the UK and beyond. Over its 20-year lifespan, its psychometric properties have been frequently investigated.

Background: Currently, flour quality evaluation methods are varied, but there are some issues, such as single evaluation indicators and insufficient comprehensiveness. The present study aimed to develop a more comprehensive and rapid evaluation method for flour quality.
Results: We first measured nine key quality indicators of dough samples, raw noodle products and cooked noodle products made from wheat flour.
Health risk assessments of heavy metals in dust samples collected from classrooms in Ilorin, Nigeria and its impact on public health.

Over the past three decades, heavy metals (HMs) in indoor dust have been a significant focus due to their environmental and health risks. This study assessed HM contamination (Co, Pb, Cd, Cr, Ni, and As) in classroom and lecture theatre dust in Ilorin, Nigeria, across dry and rainy seasons. Dust samples from primary, secondary, and university settings were analyzed using atomic absorption spectrometry and ICP-OES.
