In a locally $λ$-presentable category, with $λ$ a regular cardinal, classes of objects that are injective with respect to a family of morphisms whose domains and codomains are $λ$-presentable, are known to be characterized by their closure under products, $λ$-directed colimits and $λ$-pure subobjects.

An easy and safe method of subconjunctival injection of antimetabolites in glaucoma surgery
Aim: The use of 5-fluorouracil in glaucoma surgery is associated with a high risk of corneal complications, as even minimal doses of the drug at the ocular surface inhibit corneal epithelial cell division and lead to corneal epitheliopathy and erosion ...

ON INJECTIVITY AND P-INJECTIVITY, IV [PDF]
[For part I cf. J. Math. Kyoto Univ. 27, 439-452 (1987; Zbl 0655.16012).] A left \(A\)-module \(M\) is called \(p\)-injective if for every principal left ideal \(P\) of \(A\), every \(A\)-homomorphism from \(P\) to \(M\) can be extended to \(A\) to \(M\).

Aspiration during any kind of injection is meant to ensure that the needle tip is at the desired location during this blind procedure. While aspiration appears to be a simple procedure, it has generated a lot of controversy concerning the perceived ...

MOVPE-Grown Quantum Cascade Laser Structures Studied by Kelvin Probe Force Microscopy
A technique for direct study of the distribution of the applied voltage within a quantum cascade laser (QCL) has been developed. The detailed profile of the potential in the laser claddings and laser core region has been obtained by gradient scanning ...

A versatile injection system for flow‐injection analysis [PDF]
Analyser injection systems based on the principle of flow‐injection analysis depend on the technique used. They generally take the form of an injection loop valve; the injected sample volume is determined by the volume of the valve. Injection systems are seldom designed with a time factor to define this volume.

Study on Premixed Combustion in a Diesel Engine with Ultra-multihole Nozzle
This study proposed a new low-temperature premixed combustion mode to achieve the simultaneous reduction of NOx and soot emissions in a volume production diesel engine of CA6DF by reconstructing key systems. Some developments of this diesel engine are as

ON INJECTIVITY AND P-INJECTIVITY
The following results are extended from P-injective rings to AP-injective rings: (1) R is left self-injective regular if and only if R is a right (resp. left) AP-injective ring such that for every flnitely generated left R-module M, R(M=Z(M)) is projec- tive, where Z(M) is the left singular submodule of RM; (2) if R is a left nonsingular left AP ...
