ABSTRACT The operation of stepped spillways is limited by Exfoliant a range of discharges due to the risk of occurrence of the cavitation phenomenon and erosion on its steps.Since there is a demand for spillways with the possibility of overflow of greater discharges, the designs seek to increase the air concentration of the flow, which can occur th
IntroductionDust storms are meteorological phenomena that usually occur in arid and semi-arid regions with an annual rainfall of less than 200 to 250 mm when strong winds blow with a high speed.Dust particles affect plants growth and development directly by depositing in shoot or indirectly by changing soil chemical properties (Maletsika et al., 20
Abstract In association with the mortality rate due to air pollution, vehicular emitted fine particles (PM2.5) are a threat to public health.PM2.5-induced in-vivo studies on environmental microorganisms can be used to assess the adverse impacts of PM2.5 on human health.In the present study, the 517 toxicity of traffic-related-air-pollutant (TRAP) P
A sliding vibration isolation system, affected by a kinetic friction force, provides a flexible or energy dissipation system for a structure.The kinetic friction coefficient of the contact surfaces between the moving parts changes with the relative moving velocity of the two contact surfaces.In this study, a smart measuring device is proposed to me
