Injectivity and Graded Injectivity
Southeast Asian Bulletin of Mathematics, 2003The injectivity and graded injectivity of modules is studied. Injective testing sets of semiprime noetherian rings and FBN rings are particularily investigated. It is proved that gr-injectivity implies injectivity for commutative artinian graded rings graded by the integers, and also it is proved that the gr-global dimension and global dimension are ...

AbstractSpinal pain is a common complaint and cause of disability in the United States, affecting most individuals at some point in their lives. The complex anatomy of the spine leads to multiple potential and coexisting etiologies for pain, and the differentiation of these sources can present a diagnostic challenge.

Injective and Weakly Injective Rings
Canadian Mathematical Bulletin, 1988AbstractLet V be a variety of rings and let A ∊ V. The ring A is injective in V if every trianglewith C ∊ V, m a monomorphism and f a homomorphism has a commutative completion as indicated. A ring which is injective in some variety (equivalently, injective in the variety it generates) is called injective.

Temperature-dependent polymerising polyethylene oxide hydrogel was used as a vehicle to deliver bone marrow mesenchymal cells by injection in six nude mice, four mice acting as controls, to study generation of new bone in the cell-hydrogel complex. Mesenchymal cells were harvested by in vitro cell culture, and cells were seeded into polyethylene oxide ...

Slowly polymerizing calcium alginate gels were investigated as a means of delivering large numbers of isolated chondrocytes by means of injection to determine if these gels would promote engraftment and could provide three-dimensional templates for new cartilage growth.
