the synthesis, spectroscopy and magnetic characterization of five new dinuclear copper(ii) complexes are described. all five compounds have the general formula [cu2(l)4(o-r)2](cl)2 or [cu2(l)2(cl)2](cl)2, in which r = ch3 or h, l=2, 3 or 4-pyridinemethanol as l2, l3 or l4, respectively. the title compounds consist of dinuclear units with bridging methoxo groups in [cu2(l4)4(o-ch3)2](cl)2, hydro...

Symmetry formulated by group theory plays an essential role with respect to the laws of nature, from fundamental particles condensed-matter systems. Here, combining symmetry analysis and model calculations, we elucidate that crystallographic groups a vast number magnetic materials light elements, in which neglect relativistic spin-orbit coupling (SOC) is appropriate approximation, are considera...

Social phobia is characterized by a fear of negative evaluation within social or performance situations, where individuals believe that they are under scrutiny and may be embarrassed (American Psychiatric Association, 2013). The present study was carried out to examine the effectiveness of mindfulness and acceptance-based group therapy on decreasing fears of scrutiny by others in patients with ...

antioxidants are compounds which can prevent biological and chemical substances from oxidative damage by reactive oxygen species. flavonoids are the most important class of polyphenolic compounds that because of their antioxidant characters possess biological activities and pharmacological effects. chrysin-6-c-fucopyranoside and chrysin-3-malonyl-6-c-fucopyranoside are mono c-glycosyl derivativ...

abstract. academic spin-offs are recognized as the main means of technology transfer, contribute to the commercialization of the results of academic research, leading to society wealth creation. academic spin-offs start with some major disadvantages related to their liability of newness, smallness and their university origination. it is been argued that academic spin-off need to strengthen thei...
