Soil salinization represents a significant challenge to the ecological environment in arid areas, and digital mapping of soil salinization as well as exploration of its spatial heterogeneity with crop growth have important implications for national food security and salinization management.However, the machine rme ufx iii learning models currently
Background and Aim: Coronaviruses are a large family of viruses that cause disease in humans and animals.Coronavirus Disease 2019 (COVID-19) is an acute respiratory infectious disease caused by a new coronavirus.The World Health Organization has declared this infectious disease as a global pandemic.Objective: This study aims to review the latest re
In traditional reinforced concrete, the alkaline pore solution which passivates the steel rebars will get neutralized with time in an exposed environment.Therefore, to prevent corrosion initiation, the permeability of the concrete is reduced and extra-thick concrete covers the steel rebars.Aluminum is passive in the neutralized environment, but the
Since double-suction centrifugal pumps consume quantities of energy, revealing critical factors for energy dissipation is helpful for energy-saving design.This study aims to investigate the relationship between energy dissipation and vortex based on Rortex car mackwell method in a double-suction centrifugal pump.Detached eddy simulation was applied
