Vibration assist machining is a modern mechanical manufacturing technology which is aimed at achieving an efficient high-quality machining.This article focuses on a new-type vibration assisted machining platform which based on the stiffness and frequency requirement to obtain the key structural parameter and nature frequency of the platform by usin
BACKGROUND: Since the very first outbreak, scientists have been trying to determine the most critical pathogenetic mechanisms for the development of COVID-19 and related complications, analyze individual subpopulations of patients with chronic diseases and develop optimal tactics to combat not only the infection itself but also its acute and chroni
This study aims to simulate the stabilised stress-strain hysteresis loop of dual phase (DP) steel using micromechanical modelling.For this purpose, the investigation was conducted both experimentally and numerically.In the experimental part, the microstructure characterisation, monotonic tensile tests and low cycle fatigue tests were performed.In t
This paper analyzes the impact of the hegemonic paradigm of global mental health (GMH) on Portugal.We specifically argue that GMH in Portugal has effected a change of priorities in health policies, favoring the prevention and treatment of common mental disorders to the detriment of the deinstitutionalizing process.Diffused through the media, this m
