Joint clearance is unavoidable in the revolute joint of multi-link mechanism.Excessive value of joint clearance generally leads to the noise, vibration, and fatigue failure.In this paper, a multi-link articulated mechanism system with three revolute clearance joints is selected as the study object.At first, its ideal motion equations and dynamic re
Abstract Background Synthetic dyes represent a broad and heterogeneous class of durable pollutants, that are released in large amounts by the textile industry.The ability of two immobilized metalloporphines (structurally emulating the ligninolytic peroxidases) to bleach six chosen dyes (alizarin red S, phenosafranine, xylenol orange, methylene blue
Background and Aim: By application of casein phosphopeptide amorphous calcium phosphate (CPP-ACP) as a remineralizing agent, it may be feasible to only remove the carious dentin and better preserve the tooth structure.This study Lampshade aimed to assess the shear bond strength of composite to primary enamel treated with CPP-ACP using total-etch an
