Abstract Background The scarce knowledge about the drivers of demand for respiratory health care in the Brazilian Amazon, where the gap of human and physical health care resources is wide, is expanded with two surveys conducted in the west of the region, in Acre state.Potential drivers, informed by a review of twelve recent papers, were classified
This study investigates the effects of long-term heavy traffic loading on the performance of steel slag asphalt mixtures (SSAMs), including their high-temperature stability, low-temperature crack resistance, water stability, skid resistance, fatigue resistance, and volumetric stability.AC-13 asphalt mixtures with steel slag contents of 0%, 25%, 50%
To overcome the detrimental effect of residual stress in welded joints, which affects the overall performance of the welded structure, this paper studies the magnitude and distribution of residual stress after welding and local post-weld heat treatment (PWHT).The coupled thermo-metallurgical-mechanical model for welding 6 mm thick equi-jec 7 Ti-6Al
BackgroundCancer-associated fibroblasts (CAFs) are essential tumoral components of gastric cancer (GC), contributing to the development, therapeutic resistance and immune-suppressive tumor microenvironment (TME) of GC.This study aimed to explore the factors related to matrix CAFs and establish a CAF model to evaluate the prognosis and therapeutic e
Essential transition metals and non-essential metals often co-exist in arable soils.In plants, some transition metal transporters, such as the natural resistance-associated macrophage proteins (NRAMPs), poorly selectively transport metals with similar chemical properties whether they are essential or non-essential.In this study, a member of the NRA
