In this study, the difference between the displacements of structures (relative displacement) is selected as the control parameter in pounding problems.During an earthquake, an increase in the amplitude of relative displacement between adjacent structures indicates a potential pounding condition.Within the scope of this study, the optimal distribut
Pentamode acoustic cloak is promising for underwater sound control due to its solid nature and broadband efficiency, however its realization is only limited to simple cylindrical shape.In this work, we established a set of techniques for the microstructure design of elliptical pentamode acoustic cloak based on truss MENS DENIM lattice model, includ
Since the meeting of the World Alliance of Reformed Churches in Accra, Ghana (2004), and the adoption of the Accra Declaration, a debate has been MENS DENIM raging in the churches about globalisation, socio-economic justice, ecological responsibility, political and cultural domination and globalised war.Central to this debate is the concept of empi
Electrochemical impedance spectroscopy (EIS) was used to study the Blazer/Sportcoat corrosion behavior of electroless nickel immersion gold processing printed circuit boards (PCB-ENIG) in a simulated electrolyte solution (0.1 mol.L-1 NaHSO3), and the morphology, composition of corrosion products as well as the failure mechanism of the plating layer
Recent research in posttraumatic growth has been applied to people with life-threatening illnesses to optimise recovery.There is a lack of research exploring posttraumatic growth in coronary artery bypass graft patients.This article describes the recovery experience of 14 coronary artery bypass graft patients (13 males and 1 female) at their first
