The title compound, C(29)H(27)Cl(2)N(5)O(2), contains a central pyridine ring and two functionalized pyrazoline rings. The pyridine ring and the two attached pyrazoline rings are nearly coplanar, whereas the terminal chloro-phenyl rings are nearly perpendicular to the attached pyrazoline rings [dihedral angles = 86.78 (1) and 77.70 (1)°]. Mol-ecules are linked by weak inter-molecular C-H⋯O hydr...

A new characteristic property of von Neumann regular rings is proposed in terms of annihilators of elements. An ELT fully idempotent ring is a regular ring whose simple left (or right) modules are either injective or projective. Artinian rings are characterized in terms of Noetherian rings. Strongly regular rings and rings whose two-sided ideals are generated by central idempotents are characte...

In the title compound, C(14)H(12)ClNO, the central acetamide plane forms dihedral angles of 76.0 (2) and 64.0 (2)° with the phenyl rings and the phenyl rings form a dihedral angle of 71.8 (2)° with each other.

Multipliers play a vital role in digital systems especially in digital processors. There are many algorithms and designs were proposed in the earlier works, but still there is a need and a greater interest in designing a less complex, low power consuming, fastest multipliers. Reversible logic design became the promising technologies gaining greater interest due to less dissipation of heat and l...

The authors deal with design and analysis of an air-core electromagnetic fault current limiter (FCL) rotary motion. proposed device is characterised by a simple structure, fast operating speed reversible operation. It consists two movable concentric air core spherical reactor rings (i.e. inner outer rings) variable mutual angular displacement. At normal condition, reactors are approximately ali...

The asymptotic variance is an important criterion to evaluate the performance of Markov chains, especially for central limit theorems. We give variational formulas discrete-time (non-reversible) chains on general state space. provide many applications, extending classical Peskun’s comparison theorem non-reversible and obtaining several theorems between with various perturbations.
