Central Armendariz Rings
(Bulletein of the Malaysian Mathematical Sciences Society, 2011)
We introduce the notion of central Armendariz rings which are a
generalization of Armendariz rings and investigate their properties. We show
that the class of central Armendariz rings lies strictly between classes of ...
On Principally Quasi-Baer Modules
(Aulona Press, 2011)
Let R be an arbitrary ring with identity and M a right R-module
with S = EndR(M). In this paper, we introduce a class of modules that is
a generalization of principally quasi-Baer rings and Baer modules. The mod-
ule ...
On a Class of Semicommutative Rings
(Department of Mathematics, Kyungpook National University, 2011)
In this paper, a generalization of the class of semicommutative rings is inves-
tigated. A ring R is called central semicommutative if for any a; b 2 R, ab = 0 implies arb
is a central element of R for each r 2 R. We ...
Su, Her Yerde Su…
(Dünya Gazetesi, 2011)
Su çok önemli küresel bir üründür. Yer kabuğunun %70'i su ile kaplıdır. Bu su kütlesinin %97,5'i tuzlu, %2,5'i ise tatlı sudur. Tatlı suyun 2/3'ünü buzullar ve yer altı suları oluşturur. İnsanlar dünyadaki suların ancak ...
Accelerated Corrosion Behaviors of Zn, Al AND Zn/15Al Coatings on a Steel Surface
(Inst za kovinske materiale in tehnologie, 2011)
Zn, Al and Zn/15Al coatings can be produced in optimum conditions by the twin wire arc (TWEA) spraying technique. The
coatings are used for corrosion protection in a variety of industrial applications. In this study, the ...
