Kinship testing of a father and his son from Guangxi, China, the location of the Zhuang minority people, was performed using the PowerPlex® 18D System with a short tandem repeat typing kit. The results indicated that both the father and his son had an off-ladder allele at the Penta D locus, with a genetic size larger than that of the maximal standard allelic ladder. To further identify this loc...

We study the narrow decay width of low-lying penta-quark baryons in the QCD string theory in terms of gluonic excitations. In the QCD string theory, the penta-quark baryon decays via a gluonic-excited state of a baryon and meson system, where a pair of Y-shaped junction and anti-junction is created. Since lattice QCD shows that the lowest gluonicexcitation energy takes a large value of about 1 ...

The combined effect of mean flow and rotation on hexagonal patterns is investigated using Ginzburg-Landau equations that include nonlinear gradient terms as well as the nonlocal coupling provided by the mean flow. Long-wave and short-wave side-band instabilities are determined. Due to the nonlinear gradient terms and enhanced by the mean flow, the penta-hepta defects can become unstable to the ...

In the title compound, [Fe(C(5)H(5))(C(11)H(8)Br)], the distance of the Fe atom from the centroids of the unsubstituted and substituted cyclo-penta-dienyl (Cp) rings is 1.644 (1) and 1.643 (1) Å, respectively. The ferrocenyl moiety deviates from an eclipsed geometry, with marginally tilted Cp rings and an inter-planar angle between the Cp and benzene rings of 13.0 (4)°. The crystal structure is...

In the title compound, [Ti(C(8)H(13)Si)(C(11)H(21)Si(2))Cl(2)], the Ti(IV) atom is bonded to two Cl atoms, one 1,3-bis-(trimethyl-sil-yl)cyclo-penta-dienyl (Si(2)Cp) and one (trimethyl-sil-yl)cyclo-penta-dienyl ring (SiCp). The Si(2)Cp centroid-titanium distance is 2.0763 (10) Å and the SiCp centroid-titanium distance is 2.0793 (10) Å. The angle subtended at the Ti atom by the centroids of both...

The title compound, [Fe(C(11)H(11)N(2)O)(2)], crystallizes with two independent mol-ecules in the asymmetric unit which have have different conformations. In one mol-ecule, the two ferrocene cyclo-penta-dienyl rings are fully eclipsed and the two pyrazole rings are syn to each other; in the other, the two cyclo-penta-dienyl rings are synclinal and the pyrazole rings are anti. In both mol-ecules...

via a photolytic condensation reaction. After exposing small pieces of penta-treated wood for 20 days to natural and artificial light, measured OCDD concentrations of about 70 ppm (ng OCDD/mg PCP). The OCDD in turn degraded to HpCDD and HxCDD (heptaand hexa-chlorodibenzodioxin). The final concentration of HxCDD was approximately 15 20 ppm. When P-9 oil was used as the solvent for penta, concent...

In the title mol-ecule, [Fe(C(5)H(5))(C(16)H(12)N)], the cyclo-penta-dienyl rings are approximately eclipsed and the inter-planar angle is 0.8 (7)°. The Fe atom is slightly closer to the substituted cyclo-penta-dienyl ring, with an Fe⋯centroid distance of 1.639 (2) Å, compared with 1.645 (2) Å for the unsubstituted ring. The C=N double bond is essentially coplanar with the substituted cyclo-pen...

The mol-ecular structure of the title compound, [Fe(C9H6BrS)(C13H7F6)], consists of a ferrocene backbone with a bis-(tri-fluoro-meth-yl)phenyl group at one cyclo-penta-dienyl ring and a thio-phene heterocycle at the other cyclo-penta-dienyl ring. The latter is disordered over two sets of sites in a 0.6:0.4 ratio. In the crystal structure, intra-molecular π-π inter-actions between the thienyl an...
