this paper shows how multifractal analysis can be used to characterize the spatial distribution of epicenters in the zagros and alborz-kopeh dagh regions of iran. the main multifractal characteristics, dq, f(αq), τq, αq and a set of multifractal parameters defined from the shape of the f(αq)-spectrum including the width of f(αq)-spectrum, nonuniformity factor, combined parameter, coefficients o...
in the last 150 year, most destructive earthquakes of kopeh dagh occurred near quchan. these earthquakes caused large damages to quchan (tchalenko, 1975; ambraseys and melville, 1982). the kopeh dagh zone accommodates a motion, by a combination of slip-partitioning in the nw, thrust faulting in the se, and anticlockwise block rotation in the central kopeh dagh (hollingsworth et al. 2006, 2008)....

Homoleptic metal-sugar complexes were obtained in the form of MnIIand FeII-diacetoneglucose derivatives. The protolysis of [Mn3Mes6] and [Fe2Mes4] (Mes ) 2,4,6-Me3C6H2) with DAGH (1,2:5,6-di-O-isopropylideneR-D-glucofuranose, diacetoneglucose) led to [M(DAG)2] [M ) Mn (1), Fe (2)]. Although monomeric in solution, they showed a different degree of aggregation in the solid state, iron being monom...
In our recent paper on Palaearctic Docosia Winnertz, 1863, a new species was described under the name Docosia turkmenica Kurina & Ševčík, 2012. The material originated from the Kopet Dag Mountains (Big Bakhcha River) in southwest Turkmenistan and was named for its occurrence in the country (Kurina & Ševčík 2012).
