Atomic nuclei are finite many-body systems governed by the laws of quantum mechanics. The quest for a thorough understanding of the quantum structure of nuclei is far from finished, even after some seventy years of investigation, because such many-body quantum systems are so complex. In Physical Review Letters, Deyan Yordanov at the Max Planck Institute for Nuclear Physics, Germany, and co-work...
siilver tetrafluoroborate complex of 5.11.17.23-tetra-tert-butyl-25-26,27,28-tetrakis (diphenylphosphinoylmethoxy)calyx[4]arene (l) has been synthesized by reaction of silver tetrafluoroborate and l in dichloromethane at room temperature. the complex formed has a 1:1 metall/ligand ratio. 1h and 31p nmr data support an encapsulated structure of the complex in which silver ion is located inside t...
Electronic Structure Investigation of Octahedral Complex and Nano ring by NBO Analysis: An EPR Study
To calculation non-bonded interaction of the [CoCl6]3- complex embedded in nano ring, we focus on the single wall boron-nitride B18N18 nano ring. Thus, the geometry of B18N18 nano ring has been optimized by B3LYP method with EPR-II (Electron paramagnetic resonance) basis set and geometry of the [CoCl6]3- complex has been optimized at B3LYP method with Aldrich’s VTZ basis set and Stuttgart RSC 1...

The effect of alkyl substituents on the C-phenyl and/or the N-Phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. The predominant configuration in CHCl3 is determined by steric and electronic effects. Substituents on the C-phenyl ring favor the cis configuration, while substituents in the N-phenyl ring favor a trans c...
This paper presents the results of a preliminary study of the factor structure, concurrent validity and reliability of the Depression, Anxiety and Stress Scales (DASS) amongst an adult sample recruited from the community. The original DASS has 3 subscales, each of which consists of 14 items. All participants completed DASS, Beck Depression Inventory (BDI) and Four Systems Anxiety Questionnaire ...

Zinc (II) complex, [Zn(25-MBTSC)2I2] (1), where (25-MBTSC = (E)-2-(2,5-dimethoxybenzaldehyde) thiosemicarbazone, has been synthesized from the reaction of ZnI2 with 25-MBTSC in methanol as solvent at 25 ºC. It was characterized by elemental analysis (CHN) and is confirmed by single-crystal X-ray diffraction analysis. The complex 1 crystallizes in a triclinic system, with space group P-ī, having...
