Kabbaj 来源：[J].Communications in Algebra(IF 0.356), 2018, Vol.46 (5), pp.2073-2082Taylor & Francis 摘要：ABSTRACT(#br)The Nagata ring R ( X ) and the Serre’s conjecture ring R ⟨ X ⟩ are two localizations of the polynomial ring R [ X ] at the polynomials of unit content and at the monic polynomials, respectively. In this paper, we contribute to the study of Prüfer condition...

The aim of this study was to describe the clinical practices in VTE prophylaxis in university and peripheral hospitals in Morocco. This is a na...

Mimouni 来源：[J].Journal of Algebra(IF 0.583), 2016, Vol.445, pp.327-351Elsevier 摘要：Abstract(#br)This paper uses objects and techniques from multiplicative ideal theory to develop explicit formulas for the core of ideals in various classes of integral domains (not necessarily Noetherian). We also investigate the existence of minimal reductions (originally establ...

Mahdou 来源：[J].Communications in Algebra(IF 0.356), 2015, Vol.43 (1), pp.249-261Taylor & Francis 摘要：This paper investigates ideal-theoretic as well as homological extensions of the Prüfer domain concept to commutative rings with zero divisors in an amalgamated duplication of a ring along an ideal. The new results both compare and contrast with recent results on trivial rin...

Kabbaj 来源：[J].Journal of Algebra(IF 0.583), 2016, Vol.466, pp.169-183Elsevier 摘要：Abstract(#br)In this paper, we prove an extension of Zaks' conjecture on integral domains with semi-regular proper homomorphic images (with respect to finitely generated ideals) to arbitrary rings (i.e., possibly with zero-divisors). The main result extends and recovers Levy...
