In this note, we introduce abelian modules as a generalization of abelian rings. Let R be an arbitrary ring with identity. A module M is called abelian if, for any m 2 M and any a 2 R, any idempotent e 2 R, mae = mea. ...

On Semicommutative Modules and Rings
(Department of Mathematics at Kyungpook National University, 2007)
We say a module MR a semicommutative module if for any m 2 M and any a 2 R, ma = 0 implies mRa = 0. This paper gives various properties of reduced, Armendariz, Baer, Quasi-Baer, p:p: and p:q:-Baer rings to extend to ...
On Reduced and Semicommutative Modules
In this paper, various results of reduced and semicommutative rings are extended to reduced and semicommutative modules. In particular, we show: (1) For a principally quasi-Baer module, MR is semicommutative if and only ...
On a Class of Semicommutative Modules
Let R be a ring with identity,M a right R-module and S = EndR(M). In this note, we introduce S-semicommutative, S-Baer, S-q.-Baer and S-p.q.-Baer modules. We study the relations between these classes of modules. Also we ...
Production and Characterisation of Silicon Carbide Particulate Reinforced Aluminium-Copper Alloy Matrix Composites by Direct Squeeze Casting Method
In th is study, the effects of volume fraction of SiC on microstructure, hardness and tensile properties as well as density have been investigated in Al-4.5Cu-3Mg matrix al loy and its 5, 10, and 15 vol.% SiC particle ...
Structural Characterization of Boride Layer on Boronized Ductile Irons
In this work, some surface properties of ductile irons were improved by a them1o-chemical boronizing process. Boronizing wasperfom1ed in a slurry salt bath consisting of borax, boric acid and ferro-silicon at 850 and 950 ...
