Introduction: Acute Kidney Injury (AKI) and Chronic Kidney Disease (CKD) are risk factors for COVID-19 infection.Patients with kidney disease Solcreme stick also have other co-morbidities like hypertension, diabetes mellitus, cardiovascular disease that are risk factors for poor outcome in COVID-19 infections.Severe COVID-19 has multiorgan involvem
Experimental study on confined compression deformation and breakage characteristics for different types of coal particles
Dynamic disasters such as coal and gas outburst Cooktops seriously restrict the safety of mine production.Different types of coal particles reflect the coal structure, mechanical characteristics and energy storage behavior under load, which is of great significance to the study of coal and gas outburst disasters.However, there is little research on
Reliability evaluation of electromechanical braking system of mine hoist based on fault tree analysis and Bayesian network
Electromechanical braking system is the key way to improve the braking response ability of mine hoist.At present, the reliability research of electromechanical braking system is less.In order to further analyze and improve the reliability of electro-mechanical braking system, this paper adopts the reliability analysis method of electro-mechanical b
