Making Weak Antigens Strong: Preparing Immune Complexes for Injection
Cold Spring Harbor Protocols, 2021If antibodies against a particular antigen are available, that antigen can be purified and used for further immunizations, and antigens thus purified can show enhanced immunogenicity. Purified immune complexes can be injected directly, or while coupled to beads; the presence of antibodies and/or beads stimulates phagocytosis and usually will not ...

Various notions of weak injectivity over Clifford semigroups
Semigroup Forum, 2008Let \(Y\) be a semilattice and let \(S=\bigcup_{\alpha\in Y}G_\alpha\) be a Clifford semigroup, where \(\{G_\alpha\}_{\alpha\in Y}\) is a family of disjoint groups. For a cardinal number \(c\), a right \(S\)-act \(A_S\) is called `\(c\)-weakly injective' if for every right ideal \(I\) of \(S\), which has a generating set containing less than \(c ...

Weak-Injective Modules of Weak Dimension at Most One
Communications in Algebra, 2011We consider modules over integral domains R. A main purpose is to show that certain module properties assumed on R-modules of weak dimension ≤1 imply that these properties are shared by all modules in the category of R-modules. Also we prove several results involving modules of weak dimension ≤1.

WEAK GORENSTEIN PROJECTIVE, INJECTIVE AND FLAT MODULES
Journal of Algebra and Its Applications, 2012In this paper, weak Gorenstein projective, injective and flat modules are introduced and investigated. A left R-module M is called weak Gorenstein projective if there exists an exact sequence ⋯ → P1 → P0 → P0 → P1 → ⋯ of left R-modules such that: (1) all Pi and Pi are projective; and (2) M ≅ ker (P0 → P1).

Numerical Simulation Study on Weak Gel Injection
Proceedings of SPE Asia Pacific Oil and Gas Conference and Exhibition, 2000Abstract The low concentration flowing gel (LCFG) fluid diversion technique is a promising IOR method developed in recent years. The displacement mechanism of the weak gel, the physico-chemical properties and other influencing factors, specifically the gel formation, the physical characteristics, the mobility in porous media and the ...

Weak Relative Injective M-Subgenerated Modules
1997We study weak relative injective and relative tight modules in the category σ[M], where М is a right R-module. Many of the known results in the category of right R-modules are extended to σ[М]without assuming either М is projective or finitely generated. Conditions are given for a A-tight module to be weakly A-injective in σ[M]. Modules for which every

Weak injective covers and dimension of modules
Acta Mathematica Hungarica, 2015Let \(R\) be an associative ring with unit. A left \(R\)-module \(M\) is called supper finitely presented (s.f.p) if there exists an exact sequence \(\ldots\rightarrow P_{n} \rightarrow \ldots\rightarrow P_{1} \rightarrow P_{0} \rightarrow M \rightarrow 0\) and each left \(R\)-module \(P_{i}\) is finitely generated projective for all \(i\). A left \(R\)

Absolutely w-Pure Modules and Weak FP-Injective Dimensions
Results in Mathematics, 2022In the paper under review, the author studies the homological properties of absolutely \(w\)-pure modules and introduces weak FP-injective dimensions in terms of absolutely \(w\)-pure modules. Let \(R\) be a commutative ring. An \(R\)-module \(M\) is said to be an absolutely \(w\)-pure module if \(\mathrm{Ext}^1_R(F,M)\) is GV-torsion for any finitely ...

Motor Weakness After Transforaminal Epidural Steroid Injection
2017Transforaminal epidural steroid injection (TFESI) is an effective approach to deliver medication to the anterior epidural space. This approach is associated with unique risks because of proximity of the needle to susceptible anatomic structures and because of anatomic variation from patient to patient.
