A very peculiar damage patterns have been reported during Northridge earthquake of 1994 and Nisqually earthquake of 2001 caused by basement focusing. Similarly, basement de-focusing may cause lesser damage than the expectations but such inferences have not been reported. Further, as far as we know, no theoretical study related to de-focusing effects of anticlinal basement topography (ABT) is av...

The synthesis of the title compound, C(14)H(19)BrN(2)OS, involves the reaction of 4-bromo-benzoyl chloride with potassium thio-cyanate in acetone followed by condensation of the resulting 4-bromo-benzoyl isothio-cyanate with di-n-propyl-amine. Typical thio-urea carbonyl and thio-carbonyl double bonds, as well as shortened C-N bonds, are observed in the title compound. The short C-N bond lengths...

The title compound, C(23)H(24)O(6), crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angles between the benzopyran ring and the α,β-unsaturated ketone unit and between the α,β-unsaturated ketone group and the benzene ring are 9.4 (10) and 12.96 (13)°, respectively, in mol-ecule A and 1.40 (17) and 4.44 (17)°, respectively, in mol-ecule B. The two meth-...

Groundwater is essential for both water supply and environmental conservation, especially in semi-arid desert areas. Managing groundwater resources requires a thorough understanding of characteristics dynamics. The hydrogeochemical properties evolution the Essaouira synclinal basin northwest Morocco were studied this research, with 105 samples collected 2009, 2017, 2018, 2019. Water Quality Ind...

Purpose. To predict zones of increased water inflows based on geological exploration and mining-geological data in the real conditions an operating coal mine using method predictive evaluation prospects local structures for presence gas accumulations. Methodology. The research was carried out by constructing a map trend analysis. synclinal fold is allocated plan its main parameters – amplitude ...

In (1R,3S)-6,7-dimethoxy-3-(methoxydiphenylmethyl)-1-phenyl-1,2,3,4-tetrahydroisoquinoline, C(31)H(31)NO(3), (I), and (1R,3S)-2-benzyl-3-[diphenyl(trimethylsiloxy)methyl]-6,7-dimethoxy-1-phenyl-1,2,3,4-tetrahydroisoquinoline, C(40)H(43)NO(3)Si, (II), the absolute configurations have been confirmed to be R and S at the isoquinoline 1- and 3-positions, respectively, by NMR spectroscopy experiment...

State-of-the-art methods to image the earth’s subsurface using active-source seismic reflection data involve reverse time migration. This and other standard seismic processing methods such as velocity analysis provide best results only when all waves in the data set are primaries (waves reflected only once). A variety of methods are therefore deployed as processing to predict and remove multipl...

Novel Schiff base (H(2)L, 1,2-bis[(2-(2-mercaptophenylimino)methyl)phenoxy] ethane) derived from condensation of bisaldehyde and 2-aminothiophenol was prepared in a molar ratio 1:2. The ligand and its metal complexes are fully characterized with analytical and spectroscopic techniques. The metal complexes with Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and Th(IV) have been prepare...

In the title compound, C(32)H(30)N(4)O(2)S(2), the carbonyl and thio-carbonyl groups are found in a rare synclinal conformation, with an S-C⋯C-O pseudo-torsion angle of 62.6 (2)°. The mol-ecule has C(i) = S(2) point-group symmetry with a crystallographic center of inversion located in the middle of the ethyl-ene bridge. One of the symmetry-independent phenyl rings is disordered over two orienta...
