Hydration reactions of samples made from skarn-type copper tailings, blast furnace slag, Plastic Bowls quartz sand, cement clinker and natural gypsum during the process of pre-curing, autoclaving and re-curing were investigated by strength testing, X-ray diffraction analysis and scanning electron microscopy.The influences of calcium and silicon con
Background: Since the declaration of Coronavirus Disease 2019 (COVID-19) caused the by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as a pandemic, millions of people throughout the world have contracted the disease and more than 500,000 have died.While this terrible disease has brought devastation to many countries, it has
The trustworthiness of integrated circuits (ICs) has become increasingly important due to the ubiquitousness of ICs and the insecure nature of the current semiconductor supply chain.Throughout development and operation, ICs are exposed to several risks that can arise from malicious actors EFA or harsh operational conditions.Therefore, the question
