The axial fan blades used in underground mines are usually manufactured in AlSi12CuMgNi alloy (EN AC 48000).They must have a high mechanical strength to withstand the stresses resulting from the rotation speed of the rotor and a high resistance to erosive wear caused by suspended particles from underground mining and transport operations.The aim of

Central Asia is an area characterized by complex tectonics and active deformation; the related seismic activity controls the earthquake hazard level that, due to the occurrence of secondary and tertiary effects, also has direct implications for the hazard related to mass movements such as landslides, which are responsible for an extensive number of

In this paper, a Multiphysics coupling simulation model of flow and acoustics is proposed using COMSOL software, and its results are verified by comparing with experimental results of others.Then, the aerodynamic pressure above the bluff body surface at a speed of 350 km/h is simulated.Moreover, a near-zero-impedance acoustic metasurface composed o

Abstract This study aims at assessing the impact of compost application patterns on the physical (porosity, volumetric-moisture and bulk density) and the chemical traits of soil (pH, organic carbon, electrical conductivity, cation exchange capacity and soil nutrients) on the leaf nutrient concentration and growth (height, diameter, new leaf-structu

Introduction: Vaccine hesitancy has been a major barrier to mitigating the effects of COVID-19, especially in rural Oregon, USA.This study assessed the influence of political affiliation, religious identity, and rurality on vaccine hesitancy in counties across Oregon.Methods: Cross-sectional association analysis was performed using public data on U
