Abstract The damage effect of reactive fragments on titanium alloy plates is studied through experiment and theoretical analysis. oblique penetration process the effects target influenced by incident angle velocity were analyzed. results show that: Under condition 30° incidence angle, perforation formation modes are extrusion warping/tearing at 734m/s 704m/s, respectively, which result to dimen...

OBJECTIVE To assess radiological outcome of management of calcaneal fractures. METHODS The retrospective study was conducted at Aga Khan University Hospital, Karachi, and comprised data of calcaneal fractures managed between February , 2008 and February, 2014 Cases were identified through medical records, and X-rays were reviewed through digital radiology archive. Bohler\'s angle, Gissane\'s ...

Mol-ecules of the title compound, C(16)H(19)NO(2)S, are bent at the S atom with a C-SO(2)-NH-C torsion angle of -60.0 (2)°. The dihedral angle between the phenyl-sulfonyl and aniline rings is 41.7 (1)°. In the crystal, mol-ecules are packed into centrosymmetric dimers through pairs of N-H⋯O(S) hydrogen bonds.

In the title compound, C(14)H(16)N(2)O(4)S(2), the dihedral angle between the aromatic ring planes is 76.8 (3)° and the S-N-N-S torsion angle is 122.5 (3)°. In the crystal structure, mol-ecules form a chain structure by way of N-H⋯O hydrogen bonds.

The mol-ecule of the title compound, C(10)H(6)O(4)S(2), has crystallographically imposed twofold symmetry. The dihedral angle formed by the furan rings is 80.90 (8)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds into chains running parallel to the a axis [C-S-S-C torsion angle = 82.04 (11)°].

In the title compound, C(16)H(19)NO(2)S, the mol-ecule is twisted about the S-N bond, the C-S(O(2))-N(H)-C torsion angle being 53.9 (2)°. The dihedral angle between the two benzene rings is 82.1 (1)°. The crystal structure features inversion-related dimers linked by N-H⋯O hydrogen bonds.

In the title 1:1 adduct, C(10)H(8)N(2)·C(4)H(6)N(8)S(2)·, the components are connected through N-H⋯N hydrogen bonds, leading to a two-dimensional structure. The C-S-S-C torsion angle is -83.6 (1)°. The dihedral angle between pyridine rings is 1.86 (15)°.

The chain packing in ordered phases of lipid bilayers can be classified according to wide-angle X-ray diffraction (WAXS). For triclinic (T(‖)) and monoclinic (M(‖)) packing in crystalline L(c) phases, the wide-angle reflections index on an oblique lattice with spacings s(10)≠s(01)≠s(11), and each chain has four nearest neighbours. For orthorhombic (O(⊥)) packing in L(c) phases, and the rotation...

Secondary angle closure glaucomas are a distinct entity from primary angle closure glaucoma (PACG). Unlike PACG, secon­ dary angle closure glaucoma’s have an identifiable contributory factor/s for angle closure and obstruction of aqueous flow which is usually unrelieved by iridotomy. The treatment of each type of secondary angle closure glaucoma is varied, so identification of the primary cause...
