The purpose of this study was to determine fatigue in a porous magnesium bone scaffold. It applies finite element simulation in assessing bone scaffolding's fatigue behaviour with variations in axial loading based on physiological activities in humans. By applying the boundary conditions to the solid mechanics model and fatigue simulation, it subjects each specimen to a different loading of 1000 -3500 με, which gives the bone scaffold displacement variations. The simulation results of fatigue life for the porosity of 30%, 41%, and 55% show that the greater the loading, the lower the number of failure cycles on the porous magnesium bone scaffold. For a porosity of 30% with a load of 1000 -3500 με, it produces the number of failure cycles from 3.99x10 22 -3.61 x10 16 .
Product Quality Assurance (PQA) is a standard procedure to ensure product quality in practical manufacturing engineering. In this study, the PQA-procedure will be applied for academic assurance in the Mechanical Engineering Department, Sriwijaya University. The objective of this study is to generate web-based Academic Quality Assurance (AQA) in the Department, which accomplices with the National Accreditation Agency for Higher Education (BAN-PT). The development of web-based AQA was carried out using an open- source PHP, MySQL, CSS, and REST API to ensure web integration with the existing website of Sriwijaya University. The results show that this application can overcome the current problems when the Academic Quality Assurance was conducted manually. The AQA web can work smoothly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
