Introduction.Improving the quality and operational reliability of welded structures of power equipment is an urgent task of welding production.Its solution is possible on the basis of the development or selection of advanced methods and technologies of electroslag welding (ESW), which eliminate the causes of the formation of tempering cracks (TC) i

Anionic surfactants are commonly used as detergents and emulsifiers.However, these compounds are potent skin irritants.In this study, we evaluated the effect of the alkyl structure of anionic surfactants on the skin barrier function using the transmission index (TI) method.The TI method is used to measure the skin penetration rate of drugs.Sodium s

Abstract Opsins are G protein-coupled receptors (GPCRs) that have evolved to detect light stimuli and initiate intracellular signaling cascades.Their role as signal transducers is critical to light perception across the animal kingdom.Opsins covalently bind to the chromophore 11-cis retinal, which isomerizes to the all-trans isomer upon photon abso

Various diseases and failures inevitably appear on expressway roadways in water-rich strata under the long-term erosion of water.It is very difficult to support the surrounding rock of a water-rich roadway because water will corrode the anchorage bond and weaken the surrounding rock mass.In the process of supporting, damage and fracture of anchor b
