Fuel Communications, 2022 In this work, we investigated the combustion characteristics of ammonia (NH3) by blending it with various proportions of diethyl ether (DEE). We measured laminar flame speed of various NH3/DEE blends (DEE, 10–40% by mole) using a constant volume ...

Classes of Almost Clean Rings [PDF]
Algebras and Representation Theory, 2012 A ring is clean (almost clean) if each of its elements is the sum of a unit (regular element) and an idempotent. A module is clean (almost clean) if its endomorphism ring is clean (almost clean). We show that every quasi-continuous and nonsingular module is almost clean and that every right CS and right nonsingular ring is almost clean. As a corollary,

The relationships between clean rings, r-clean rings, and f-clean rings [PDF]
AIP Conference Proceedings, 2018 Suppose R is a ring with identity. R called a regular ring if each element is a regular element. A ring R is called an r-clean ring if every element in R can be expressed as the sum of a regular element and an idempotent element. An element in the ring R is called clean if it can be expressed as the sum of a unit element and an idempotent element, so ...

Trivial Ring Extension of Suitable-Like Conditions and some properties [PDF]
مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2018 We investigate the transfer of the notion of suitable rings along with related concepts, such as potent and semipotent rings, in the general context of the trivial ring extension, then we put these results in use to enrich the literature with new ...

Journal of Algebra and Its Applications, 2016 An element [Formula: see text] of a ring [Formula: see text] is nil-clean, if [Formula: see text], where [Formula: see text] and [Formula: see text] is a nilpotent element, and the ring [Formula: see text] is called nil-clean if each of its elements is nil-clean.

Miskolc Mathematical Notes, 2015 Summary: Let \(C(R)\) denote the center of a ring \(R\) and \(g(x)\) be a polynomial of ring \(C(R)[x]\). An element \(r\in R\) is called ``\(g(x)\)-clean'' if \(r=s+u\) where \(g(s)=0\) and \(u\) is a unit of \(R\) and \(R\) is \(g(x)\)-clean if every element is \(g(x)\)-clean.

Rings in which elements are the sum of a nilpotent and a root of a fixed polynomial that commute
Open Mathematics, 2017 An element in a ring R with identity is said to be strongly nil clean if it is the sum of an idempotent and a nilpotent that commute, R is said to be strongly nil clean if every element of R is strongly nil clean. Let C(R) be the center of a ring R and g(

The Strongly Nil-Clean Rings Of Order Two Units [PDF]
Al-Rafidain Journal of Computer Sciences and MathematicsIf every element of a ring R is the sum of idempotent and nilpotent that commute, then the ring is said to be a strongly nil-clean. Further features of a strongly nil-clean ring are given in this paper.

J~#-Uc cleanness and strongly J~#-Uc cleanness of rings
Nantong Daxue xuebao. Ziran kexue banA ring R is GU_cJ if U(R)=Uc(R)+J~#(R);R is (strongly) J~#-U_c-clean ring if for any a∈R,there exists g∈Uc(R),p2=p∈R,d∈J~#(R),such that ag=p+d (and ap=pa).GU_cJ rings and J~#-U_c-clean rings are proper generalizations of GUJ rings and GJ-clean rings ...
