Czechoslovak Mathematical Journal, 1987 An algebra \(A\) with a constant 0 is 0-permutable if \([0]R\circ S=[0]S\circ R\) for \(R, S\) congruences; is 0-distributive if \([0](R\cup S)\cap T=[0](R\cap S)\cup (R\cap T)\) for \(R, S, T\) congruences; is 0-arithmetical if it is 0-permutable and 0-distributive. Similarly for varieties.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Deformation Behavior of La2O3‐Doped Copper during Equal Channel Angular Pressing
Advanced Engineering Materials, EarlyView.By additions of strengthening elements and/or structure optimization, the mechanical properties of copper can be increased while keeping favorable electric conductivity. By combining addition of La2O3 and processing by equal channel angular pressing, substructure development is achieved, leading to increase in microhardness to more than double the ...
