Some Results on AWN-injective Rings

NTU Journal of Pure Sciences
A concept of AWN-injective ring is defined by [1], that is, for any   there exists  and an Y-sub module  of  (  is aright -module) such that  and  as left S-module with S=End(u ). If  is AWN-injective module, then we call  aright AWN-injective ring.

Non-reduced valuation rings and descent for smooth blowup squares [PDF]

We consider a class of non-reduced valuation rings, known in the literature as chain rings. We observe that the Grothendieck topology generated by the Zariski topology and smooth blowup squares is exactly the topology which has chain rings for its local ...

Research on the Impact of Labyrinth Seal Ring Tooth Profile on the Pressure Pulsation of Leakage Chambers in High-Speed Centrifugal Pumps

Lubricants
The gap seal ring is a critical component in high-speed centrifugal pumps. The leakage rate and performance of the pump are sensitive to variation in seal ring parameters.

Neck dose-limiting rings reduce head and neck lymphedema in early nasopharyngeal carcinoma patients undergoing IMRT: a dosimetric-clinical validation

Scientific Reports
This study aimed to determine the optimal limiting dose to reduce head and neck lymphedema in patients with early nasopharyngeal carcinoma (NPC) receiving intensity-modulated radiotherapy (IMRT) by setting dose limiting rings at the anterior and ...

Central Armendariz rings [PDF]

, 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 Ar- mendariz rings and abelian rings.
