DIAMONDS IN THE ROUGH - RECONSIDERING THE SCIENTIFIC AND HERITAGE VALUE OF HEAT-ALTERED STONES IN PREHISTORIC ARCHAEOLOGY THROUGH A SYSTEMATIC LITERATURE REVIEW [VERSION 1; PEER REVIEW: 2 APPROVED]

Background Heat-altered stones (HAS) are commonly reported in prehistoric sites across several continents, yet they continue to be generally overlooked and systematic studies on them are scarce.Methods We performed a systematic literature review which consisted of searching journal articles, book chapters and books published in English, in Scopus a

Atherosclerosis is the main cause of coronary heart disease and stroke, the two major causes of death in developed society.There is emerging evidence of excess risk of cardiovascular disease at low radiation doses in various occupationally exposed groups receiving small daily radiation doses.Assuming that they are causal, the mechanisms for effects

The two peaks characteristic of yellow and blue light in the spectrum of dual-wavelength white light emitting diodes (LEDs) introduce distinctive features to the interference signal of white light scanning interferometry (WLSI).The distinctive features are defined as discontinuities, so that the fringe contrast function cannot be modeled as a singl

This study investigates the problem of asymptotic stabilization of underactuated surface vehicles (USVs) in the presence of simultaneous matched and mismatched disturbances.Within the framework of back-stepping control and by introducing a periodic term in the cucharas reservoir control laws of virtual yaw angle and surge velocity, a control design

Ensuring the reliability and safety of technical systems is a milestone in their development and mass production.Reliability testing of technical systems is performed in special laboratories and centers.Today, there is a great deal of experience in simulating operating conditions of technical systems in order to predict and increase their reliabili
