BackgroundThe importance of advance care planning (ACP) has been highlighted by the advent of life-threatening COVID-19.Anecdotal evidence suggests changes in implementation of policies and procedures is needed to support uptake of ACPs.We investigated the barriers and enablers of ACP in the COVID-19 context and identify recommendations to facilita
Due to the harsh working environment of hydraulic excavators, the actuators are subjected to high intensity and long duration, resulting in fatigue-induced cracks, fractures, and other failures, leading to work interruptions and delays, reducing the operational efficiency of the excavator.Therefore, fatigue life prediction is of great significance
In this work, new biodegradable ABCBA type pentablock copolymers with different mole ratio of L-lactide and PPDO-b-PEG-b-PPDO triblock copolymer were synthesized and characterized.In the first step, PPDO-b-PEG-b-PPDO triblock copolymer was synthesized via a ring-opening polymerization of P-DiOxanone (PDO) monomer with Poly (Ethylene Glycol) (PEG) u
