Through Sealed Beam Conversion Assembly dynamic simulation of the cross-hinge four-bar mechanism, it is found the primary reason for unbalance of the mechanism results from the unequal swing angle of driving link and driven link.To simplify analysis and calculation, a spatial switching approach was proposed to switch nonlinear problem into linear p

Marine protected areas (MPAs) serve as a potential defense against marine degradation, meeting the conflicting priorities and needs of multiple actors.Biodiversity, conservation, and ecotourism constitute a triad of sustainability tropes in tropical MPAs that intersect with and reinterpret local histories of marine interaction, subsistence, and com

OBJECTIVE: The homicide rate for children and adolescents in Recife, Brazil,mostly caused by firearms, is one of the highest that has been reported.The present case-control study was designed to identify factors that were potentially modifiable through preventive interventions.METHODS: Cases were 255 homicide victims under 20 years of age, who had

In this work, a new constrained numerical optimization approach is proposed for solving offline the Inverse Kinematics Problem (IKP) of articulated robots, which consists on optimizing the joint displacement while the end effector is positioned and oriented in a desired pose.The novelty of this approach is in the formulation of the optimization pro

Recent Indian rule Building Supplies on compensation for any injury or death of the subject in a clinical trial, has generated a lot of discussion on its impact on clinical trials in India.The legal process in the compensation rule is based on the causality assessment.However, it ignores the scientific basis of causality assessment.This could have
