In the title compound, [Co(II)Cl(2)(C(6)H(10)N(2))(2)], a pair of 3,4,5-trimethyl-pyrazoles act as monodentate ligands. Two Cl(-) anions are also bonded directly to the Co(II) atom, which has a CoN(2)Cl(2) chromophore in a slightly distorted tetra-hedral geometry. The two mol-ecules in the asymmetric unit are related by an approximate twofold rotation roughly parallel to the a axis. The amino H atom in the pyrazole ring participates in weak N-H⋯Cl hydrogen bonds to form chains that propagate roughly parallel to the c axis.

Enantiornithes are the most successful early-diverging avian clade, their fossils revealing important information regarding the structure of Cretaceous avifaunas and the parallel refinement of flight alongside the ornithuromorph lineage that includes modern birds. The most diverse recognized family of Early Cretaceous enantiornithines is the Bohaiornithidae, known from the Jehol Biota in northeastern China. Members of this clade enhance our understanding of intraclade morphological diversity and elucidate the independent evolution of this unique lineage.

Manipulator-focused views hold, roughly, that the reason that Victim lacks responsibility (or lacks full responsibility) is because of the way the action is related to the Manipulator. First, we introduce these views generally, and then we survey some detailed versions of such views.

Naturally occurring cellulose Iβ with its characteristic parallel orientation of cellulose chains is less stable than cellulose II, in which neighboring pairs of chains are oriented antiparallel to each other. While the distinct hydrogen-bond patterns of these two cellulose crystal forms are well established, the energetic role of the hydrogen bonds for crystal stability, in comparison to the van der Waals (vdW) and overall electrostatic interactions in the crystals, is a matter of current debate. In this article, we investigate the relative stability of celluloses Iβ and II in energy minimizations with classical force fields.

Standard models of lexical production assume that speakers access representations of meaning, grammar, and different aspects of sound in a roughly sequential manner (whether or not they admit cascading or interactivity). In contrast, we review evidence for a parallel activation model in which these representations are accessed in parallel. According to this account, word learning involves the binding of the meaning, grammar, and sound of a word into a single representation.

Four parallel simultaneous sludge thickening and reduction reactors using flat-sheet membranes were employed for the aerobic digestion of sludge to explore the characteristics of dissolved organic matter and its membrane fouling effect. During the initial 8 days of using flat-sheet membranes for simultaneous sludge thickening and reduction (MSTR), a notable increase was observed in the concentrations of humic acids and compounds that resemble soluble microbial by-products in the effluent. Subsequently, a fluctuating trend in humic acid levels ensued, accompanied by a gradual decline in soluble microbial by-product-like substances.
