In the crystal of the title compound, C(12)H(9)Cl(2)NO(2)S, the mol-ecule is twisted at the S atom with a C-SO(2)-NH-C torsion angle of -58.4 (3)°. Furthermore, the N-H bond in this segment is anti to the meta-chloro group. The dihedral angle between the aromatic rings is 77.1 (1)°. The crystal structure features inversion-related dimers linked by N-H⋯O hydrogen bonds.

In the title mol-ecule, C(10)H(13)N(3)O(3)S·2H(2)O, the thio-semi-carbazide =N-NH-C(=S)-NH- fragment [torsion angle = 0.2 (1)°] is nearly coplanar with the benzene ring [dihedral angle = 2.4 (1)°]. The benzene ring and semicarbazide moiety are located on opposite sites of the C=N bond, showing an E configuration. The hy-droxy, imino and water H atoms are engaged in extensive hydrogen bonding, f...

In the title compound, C13H13NO3S, the dihedral angle between the benzene rings is 64.15 (7)° and the C-S-N-C torsion angle is -57.18 (12)°. An intra-molecular N-H⋯O hydrogen bond closes an S(5) ring. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into C(8) chains propagating in [100]. Weak C-H⋯π inter-actions are also observed.

In the title compound, C(11)H(14)O(5)S, there is an intra-molecular C-H⋯O hydrogen bond, for which the C-C-S-O torsion angle involving the acceptor and donor atoms is 2.4 (4)°. The dihedral angle between the benzene ring and the methoxy-carbonyl plane is 52.7 (4)°. In the crystal structure, mol-ecules are linked via inter-molecular C-H⋯O hydrogen bonds, forming a mol-ecular chain along the b axis.

BACKGROUND Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) carries a risk of sudden death. We aimed to assess whether vectorcardiographic (VCG) parameters directed toward the right heart and a measured angle of the S-wave would help differentiate ARVD/C with otherwise normal electrocardiograms from controls. METHODS Task Force 2010 definite ARVD/C criteria were met for all ...

The asymmetric unit of the title salt, 2C(4)H(12)NO(+)·C(14)H(8)O(4)S(2) (2-), contains an eth-yl(2-hydr-oxy)aminium cation and half a 2,2'-disulfanediyldibenzoate anion, with the latter disposed about a twofold axis. The cation is a straight chain with the exception of the terminal hydr-oxy group [the N-C-C-O torsion angle is 66.5 (2)°]. A twisted conformation is found for the anion [the C-S-S...

Abstract This work presents comprehensive numerical research on the impact load of trans-medium aircraft (TMA) using coupled Eulerian-Lagrangian (CEL) method during a water-entry event. The velocity, angle, and attitude play significant role in characteristics trajectory. In this paper, model typical TMA structure is established to study with velocity 0, 2m/s, 4m/s, 6m/s, 8m/s, angle 90°, 80°, ...

We have observed for the first time reflection spectra of an electric quadrupole transition for the cesium atom (6 (2)S(1/2)-5 (2)D(5/2)) line at an angle of incidence from theta(c)-11.9 to theta(c)+107.5 mrad, where theta(c) is the critical angle for total reflection. From a comparison with the calculated absorption in the attenuated total reflection, the oscillator strengths for s and p polar...

In the title compound, C(24)H(27)BrN(4)O(4)S(2), the mol-ecule is twisted at the sulfonyl S atom with a C-S(O(2))-N(H)-C torsion angle of 62.6 (3)°. The benzene rings bridged by the sulfonamide group are tilted to each other by a dihedral angle of 60.6 (1)°. The dihedral angle between the sulfur-bridged pyrimidine and benzene rings is 62.7 (1)°. The morpholine ring adopts a chair conformation. ...

Objectives: Nowadays, Snap-fits are used in the automotive industry as a proper alternative for mechanical joints, cabling joints, and car interior lining joints. Due to the special form of these joints, which are assembled manually, the contact area between Snap-fits and the worker’s fingertips can be too small. This can cause skin pain on the worker’s  fingertips. Therefore, ...
