On the arithmetic of arithmetical congruence monoids [PDF]
Colloquium Mathematicum, 2007 Let N represent the positive integers and N0 the non-negative integers. If b 2 N and is a multiplicatively closed subset of Zb = Z/bZ, then the set H = {x 2 N | x + bZ 2 } ( {1} is a multiplicative submonoid of N known as a congruence monoid. An arithmetical congruence monoid (or ACM) is a congruence monoid where = {a} consists of a single element.

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 ...

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.

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 ...
