Abstract:
The new complex [V(C5H5)2Br]2(μ2-F)2[V(C5H5)Br]+[BF4]− has been isolated from the reaction of vanadocene monobromide with the ferrocenium cation. The complex is a mixed valence compound composed of two V(IV) and one V(III) centers. The V(III) center has one cyclopentadienyl ligand in its coordination sphere, as well as a bromide and two fluoride ligands. Each fluoride ligand is also attached to one of the V(IV) centers, which additionally is coordinated by a bromide and two cyclopentadienyl ligands. The complex crystallizes in the monoclinic space group P21/m, with a=7.66490(10) Å, b=15.2457(2

The metallocene-catalyzed copolymerization of ethylene and 11–bromo–1–undecene was carried out to synthesize brominated polyethylene (PE). A modified methylaluminoxane (MMAO) solution was used as a cocatalyst and rac–Et(H4Ind)2ZrCl2 as a catalyst. The copolymerization showed a high activity and afforded the copolymer with a 11-bromo-1-undecene incorporation ranging from 1.0 to 4.3 mol%. When using a dried methylaluminoxane (dMAO) as a cocatalyst, the incorporation ratio of 11-bromo-1-undecene increased remarkably to 25.2 mol%.

Direct comparison of the iodo complex with the chloro and bromo complexes shows that the iodo complex is partly chemically transformed to a square-planar PtI3complex bound to the Nδatom of His15, a chemical behaviour that is not exhibited by the chloro or bromo complexes. Each complex does, however, bind to HEWL in its octahedral form either at one site (PtI6) or at two sites (PtBr6and PtCl6). As heav

By using the ability of the positive-strand RNA ((+)RNA) virus BMV to replicate in yeast it was previously shown that subunits of the LSm1-7 ring, as well as Pat1 and Dhh1 play an essential role in the transit of the BMV genome from translation to replication. In non-infected cells, these proteins mediate the transition of cellular mRNAs from a translational to a non-translational state by activating decapping in the 5'-3' - deadenylation-dependent mRNA decay pathway. Given the conservation of this pathway from yeast to humans and the common need of all (+)RNA viruses to regulate the transitio

Abstract:
The stability of a rigid body on which two forces are in equilibrium can be assessed intuitively. In more complex cases this is no longer true. This paper presents a general method to assess the stability of complex force systems, based on the notion of dynamic equivalence. A resultant force is considered dynamically equivalent to a given system of forces acting on a rigid body if the contributions to the stability of the body of both force systems are equal. It is shown that the dynamically equivalent resultant force of two given constant forces applies at the intersection of its line of acti
