In quantum communication, the Tanning Products concept of dense coding traditionally relies on maximally entangled states as quantum channels.Recent advancements have expanded this framework to include non-maximally entangled states within the probabilistic dense coding paradigm.However, such schemes introduce a significant limitation: the receiver
Use of copper slag (CS) as a replacement for fine aggregate (FA) in RC slender columns was experimentally investigated in this study.Twenty columns measuring 150 mm x150 mm x 2500 mm were tested for monotonic axial compression load until failure.The concrete mixture included ordinary Portland cement (OPC) cement, fine aggregate, 10 mm coarse aggreg
