We have performed a detailed first-principles study of the penta-AlN2 nanostructure in the Cairo pentagonal tiling geometry, which is dynamically stable due to the absence of imaginary mode in the calculated phonon spectrum. The formation energy and the fragment cohesive energy analyses, the molecular dynamics simulations, and the mechanical property studies also support the structural stabilit...

Twenty-two markers located on Muller's elements D or E have been mapped by in situ hybridization in six species of the obscura group of Drosophila and in D. melanogaster. The obscura species can be grouped into a Palearctic cluster (D. subobscura, D. madeirensis and D. guanche) and a Nearctic one (D. pseudoobscura, D. persimilis and D. miranda). Eleven of the probes contain known genes: E74, Ac...

The racemic title compound, C(54)H(38)O(2), consists of two C-linked penta-leno[1,2,3-ij]naphthalenone moieties, the crowded aryl ring substitution on the cyclo-pentane rings forcing the two segments to assume a conformation which has pseudo-twofold rotational symmetry, with a dihedral angle between the naphthalene substituent groups of 55.30 (8)°. In each segment, the two phenyl rings have dif...

The title iron(II) complex, [Fe(C16H12NO2)2], crystallizes in the ortho-rhom-bic space group Pbca with the Fe(2+) cation positioned on an inversion center. The cyclo-penta-dienyl (Cp) rings adopt an anti conformation in contrast with other substituted ferrocenes in which the Cp rings appear in a nearly eclipsed conformation. The Cp and the aromatic rings are positioned out of the plane, with a ...

Abstract We present ALMA archival data for 219–235 GHz continuum and line observations toward the hot molecular core (HMC) W 49 N MCN-a (UCHII region J1) at a resolution of ∼${0.^{\prime \prime }3}$. The dust emission, showing an elongated structure ${1.^{\prime }40} \times {0.^{\prime }95}$ (position angle = 43.°5) perpendicular to outflow seen in SiO SO, represents rotating flattened envelope...

Emotion recognition was investigated in typically developing individuals and individuals with autism. Experiment 1 tested children (5-7 years, n = 37) with brief video displays of facial expressions that varied in subtlety. Children with autism performed worse than the control children. In Experiment 2, 3 age groups (8-12 years, n = 49; 13-17 years, n = 49; and adults n = 45) were tested on the...

The study was conducted to assess a possible interaction between fungal pathogen of Fusarium culmorum Sacc. and Root lesion nematodes at sequentially simultaneously inoculation. spore suspension effect evaluated on plant disease severity nematode density moderate resistant wheat line F. (2-49) susceptible variety (?kizce) under controlled condition. higher ?kizce cv. than 2-49. This indicates t...
