$n$-cocoherent rings, $n$-cosemihereditary rings and $n$-V-rings
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. $R$...
متن کامل(4-Chlorobenzohydrazidato-κ2 N′,O)[2-(4-chlorobenzoylhydrazono-κ2 N,O)propionato(2−)-κO]oxidovanadium(V)
In the crystal structure of the title compound, [VO(C(7)H(6)ClN(2)O)(C(10)H(7)ClN(2)O(3))], the V(V) atom is N,O-chelated by the chloro-benzoyl-hydrazidate anion and O,N,O'-chelated by the (chloro-benzoyl-hydrazono)propionate dianion. The distorted octa-hedral trans-N(2)O(4) coordination geometry is completed by the vanadyl O atom. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds i...

The contradiction between evidence for and against the existence of the Θ pentaquark might be resolved if it only appears as a result of a particular production mechanism which is present in some experiments and absent in others. We examine the implications of Θ production via decay of a cryptoexotic N resonance with a mass of about 2.4 GeV corresponding to a peak in the experimental data for t...
