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)....

in order to study the stratigraphic of sedimentary deposits of the cenomanian in kopeh dagh, the taghiabad section was selected. in the eastern kopeh dagh, the upper part of aitamir formation has this time range characteristic. the upper part of this formation includes shale and glauconitic sandstones and contains variety of ammonite fauna. ten genera and species of ammonites are found inside t...

the afghan vole had not been reported from north-eastern iran until for the first time its presence was confirmed by examining the pellets of predatory birds from dargaz, kalat, sarakhs and the vicinity of mashhad through studying the molar teeth. by further sampling, colonies of this species were found in the periphery of tandoureh national park in the kopet-dag mountains and also in alpine re...

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). Unfortunately, the authors were not aware of a previous paper by Zaitzev (2011) de...
