In the title compound, C(20)H(15)N(2)O(+)·Cl(-), the dihedral angle between the fused-ring system and the benzene ring is 63.10 (7)°. In the crystal, N-H⋯Cl hydrogen bonds link the components and aromatic π-π stacking [shortest centroid-centroid distance = 3.6421 (12) Å] occurs.

In the title compound, C(10)H(8)ClN, the crystal packing shows π-π stacking between the heterocyclic ring and the aromatic ring, with a centroid-centroid distance of 3.819 Å. The crystal studied was a racemic twin, the ratio of the twin components being 0.65 (7):0.35 (7).

The Parallel computers, such as multiprocessors system-on-chip (Mp-SoCs), multicomputers and cluster computers are consisting of hundreds or thousands multiple processing units and components (such as routers, channels and connectors) connected via some interconnection network that collectively may undergo high failure rates. Normally, the faulty components are coalesced into fault regions, whi...

Abstract. We present a model for the OH megamaser emission in the starburst galaxy IIIZw35. The observed diffuse and compact OH maser components in this source are explained by a single phase of unsaturated clumpy gas distributed in a thin ring structure and amplifying background continuum. We emphasize the importance of clumpiness in the OH masing medium, an effect that has not been fully appr...

Actin filaments and myosin II are evolutionarily conserved force-generating components of the contractile ring during cytokinesis. Here we show that in budding yeast, actin filament depolymerization plays a major role in actomyosin ring constriction. Cofilin mutation or chemically stabilizing actin filaments attenuate actomyosin ring constriction. Deletion of myosin II motor domain or the myosi...

PURPOSE The aim of this study was to compare the changes in retentive force of stud attachments for implant overdentures by in vitro 2-year-wear simulation. MATERIALS AND METHODS Three commercially available attachment systems were investigated: Kerator blue, O-ring red, and EZ lock. Two implant fixtures were embedded in parallel in each custom base mounting. Five pairs of each attachment sys...

In the solid form of the title imidazolium-based ionic liquid salt, C(18)H(24)N(4) (2+)·2CF(3)SO(3) (-), the complete cation is generated by a crystallographic inversion centre. The five-membered imidazole ring is approximately perpendicular to the six-membered phenyl-ene ring [dihedral angle = 85.11 (11)°]. In the crystal, the components are linked by C-H⋯O interactions.

SMC proteins are key components of large ring-shaped chromosomal protein complexes, such as cohesin and condensin. New evidence supports the idea that these rings topologically encircle DNA. Hints also emerge as to what it may take for DNA to enter the ring.
