let $r$ be a ring, and let $n, d$ be non-negative integers. a right $r$-module $m$ is called $(n, d)$-projective if $ext^{d+1}_r(m, a)=0$ for every $n$-copresented right $r$-module $a$. $r$ is called right $n$-cocoherent if every $n$-copresented right $r$-module is $(n+1)$-coprese-nted, it is called a right co-$(n,d)$-ring if every right $r$-module is $(n, d)$-projective. $r$ ...
mndo semi-empirical scf mo calculations are used to study the pyramidal nitrogen atom inversion and configurational equilibria in the title compounds.
In this article we introduce the notion of n-capable groups. It is shown that every group G admits a uniquely determined subgroup (〖Z^n)〗^* (G) which is a characteristic subgroup and lies in the n-centre subgroup of the group G. This is the smallest subgroup of G whose factor group is n-capable. Moreover, some properties of n-central extension will be studied.
In a recent article in CHEST (March 2014) by Zuur-Telgen et al 1 about the usefulness of midrangeproadrenomedullin (MR-proADM) in predicting mortality in patients with COPD, the authors confi rm previous fi ndings by Stolz et al 2 that higher MR-proADM levels during hospitalization for an acute exacerbation of COPD are associated with increased mortality. In addition, Zuur-Telgen et al 1 demons...
