The effect of partial replacement of cement by unprocessed calcareous fly ash on fresh and hardened properties of self-compacting concrete was investigated.Concrete mixes containing 27.5%, 35%, 42.5%, 50%, 57.5% and 65% of fly ash based on the total weight of binder (cement + fly ash) Oven Mitts were tested.All the mixes were designed to have the s
In developed countries, most of the population recognizes that they are facing environmental and social threats which are mainly related to global warming.The problem associated with an ecological footprint, particularly water shortage, ecosystems, climate change, deforestation, and declining biodiversity, is considered a harmful threat to human li
Abstract Background Tissue factor pathway inhibitor (TFPI) is the main physiological inhibitor of TF-induced blood coagulation process, and may play essential roles in the pathogenesis of major adverse cardiac events.This study was designed to determine whether the variation of TFPI was related with coronary artery disease (CAD) in the Han Chinese
Abstract Optimization tasks are essential in modern engineering fields such as chip design, spacecraft trajectory determination, and reactor scenario development.Recently, machine learning applications, including deep reinforcement learning (RL) and genetic algorithms (GA), have emerged in these real-world optimization tasks.We introduce a new mach
