Effect of Temperature on the Early Development of Paralichthys olivaceus Otoliths [PDF]

open access: yesAnimals
This study aimed to investigate the influence of temperature on the early otolith growth and development in P. olivaceus by examining natural (15–19.5 °C) and constant (20 ± 0.5 °C) temperature regimes.

On CS- Rings [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2008
The main purpose of this paper is to study CS-rings. We give some properties of right CS-rings and the connection between such rings and reduced rings, regular rings, strongly regular rings, and S-weakly regular rings.

On Dual Rings [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2004
A ring R is called a right dual ring if rl(T) = T  for all right ideals T of R. The main  purpose of this  paper is to develop some basic properties of dual rings and to give the connection between dual rings, regular rings and strongly regular rings.

sπ-Weakly Regular Rings [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2007
The purpose of this paper is to study a new class of rings R in which, for each a ΠR, aΠ aR aR, for some positive integer n. Such rings are called sp-weakly regular rings and give some of their basic properties as well as the relation between sp-weakly

Rings in which Every Simple Right R-Module is Flat [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2004
The objective of this paper is to initiate the study of rings in which each simple right R-module is flat, such rings will be called right SF-rings. Some important properties of right SF-rings are obtained.

On Local Rings [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2014
A ring R is called local ring if it has exactly one maximal ideal. In this paper, we introduce some characterization and basic properties of this ring. Also, we studied the relation between local rings and Von Neumann regular rings and strongly regular ...

MGP and EGP Rings [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2010
The purpose of this paper is to study the rings in which every maximal (essential) right ideal is a left GP- ideal. Such rings will be called right MGP- rings (EGP- rings).

On MLGP- Rings [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2019
An ideal K of a ring R is called right (left) generalized pure (GP -ideal) if for every a ∈ K, there exists m ∈ Z+, and b ∈ K such that  am = am b ( am = b am) . A ring R is called MLGP-ring if every right maximal ideal is left GP-ideal.

Strongly Semiunits and Tri-Regular Elements in Rings [PDF]

open access: yesEurasian Journal of Science and Engineering, 2018
In this paper we study semiunit elements in the group ring Z2G, where G is a cyclic group and we introduce and discuss strongly semiunit elements in Zn, for n=p, 2p, p2 where p is an odd prime.
