The debris flow is one of the geological hazards; its occurrence is complex, fuzzy, and random.And it is affected by many indices; a new multi-index assessment method is proposed to analyze the risk level of debris flow based on the entropy weight-normal cloud model in Sheets Banshanmen gully.The index weight is calculated by using the entropy weig

In this paper, based on the topological description method, the kinematic and dynamic equations of the projectile flight and projectile-artillery coupling system during the whole process of firing are constructed.The factors that can affect the projectile burst points, BAKING SODA POWDER namely the state parameters of the projectile on the muzzle a

Introduction Tobacco smoking and alcohol consumption during pregnancy are particularly prevalent in low socioeconomic status populations, with an adverse association with birth outcomes and cardiometabolic risk factors.However, the direct and indirect effects of prenatal cigarette smoking and alcohol consumption during pregnancy on cardiometabolic

A comprehensive experimental study on the high-velocity oxygen-fuel (HVOF) sprayed tungsten carbide/cobalt (WC/Co) deposits using laser cladding was conducted.A response surface methodology based on a central composite design was used to analyze, predict and optimize the WC/Co deposits of Gastrointestinal - Anti-Diarrhea the laser-based HVOF spraye
