There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(14)H(11)ClN(4)O(4), with the same E conformation about the C=N double bond. The mol-ecules are approximately planar, with a dihedral angle between the benzene rings of 10.24 (12)° in one mol-ecule and 4.73 (12)° in the other. In both mol-ecules, the ortho-nitro groups of the 2,4-dinitro-phe...

The asymmetric unit of the title compound, C(14)H(14)N(2), contains two independent mol-ecules with slightly different conformations; the dihedral angles formed by aromatic rings in the two mol-ecules are 73.2 (1) and 75.0 (1)°. Inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains extended in the [100] direction.

Selection of frost tolerant cultivars and understanding the mechanisms of frost hardiness could help to improve freezing resistance in olive plants. Olive cultivars may differ in frost hardiness due to differential survival of specific organs. The aim of this study was to screen different olive cultivars based on their stomatal density and metabolic modifications under cold conditions. The ‘Zar...

The asymmetric unit of the title compound, C13H10N2O4, contains two independent mol-ecules (A and B). The dihedral angle between the aromatic rings is 48.18 (14)° in mol-ecule A and 45.81 (14)° in mol-ecule B. The mean plane of the carbamate N-C(=O)-O group is twisted slightly from the attached benzene and phenyl rings, making respective dihedral angles of 12.97 (13) and 60.93 (14)° in A, and 2...

the thermal decomposition of 86 % vinyl chloride 14 % vinyl acetate copolymer wasstudied by the conductometry technique in the presence of nitrogen. the kinetics of stability andthermal degradation of vinyl chloride- co- vinyl acetate (pvc- co- pvac) copolymer withcopper, copper oxide and tricalcium dicitrate (st) were investigated at various temperatures (150-180 oc ) in solution. the rate coe...

The title compound, C(10)H(12)N(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit. The side chains in the two independent mol-ecules have slightly different orientations, with the C=N-N-C torsion angle being 169.19 (14)° in one of the mol-ecules and -179.86 (14)° in the other. Each independent mol-ecule adopts a trans configuration with respect to the C=N bond. In the ...

The title compound, C(15)H(12)O(5)S(2), crystallizes with two mol-ecules in the asymmetric unit. In both mol-ecules, the 1,3-benzodithiole plane and the aryl ring of the anisyl group are not quite coplanar; the corresponding dihedral angles are 20.4 (1) and 18.0 (1)°. π-Stacking [with centroid-centroid distances between 3.5440 (14) and 3.8421 (14) Å] takes place along [100] between the alternat...

Abstract: In this paper, fully fuzzy linear systems in the form ° ° % A X = b ⊗ (FFLS) will be discussed, where ° n n A × is a fuzzy matrix, x and b are (n×1) fuzzy vector. Transforming fully fuzzy linear system in to two crisp linear systems and using the Jacobi iterative and Adomian Decomposition Methods (ADM) a FFLS will be solved.We will show that to find a solution for a (FFLS) our method ...
