The studied region in this research (Alborz province) is structurally located in Alborz poly_orogenic system of northern Iran. The purpose of this research is combining the remote sensing and geology sciences to show fault lineaments by analyzing satellite data in a vast region and also comparison between lineaments layer and recognized faults in geology maps. Firstly, two scenes of Landsat ETM...

Dictyozamites barnardi sp. nov. and fakhri are the second third species of to be described from Iran Middle East. They derive Rhaetic Kalariz Formation (Shemshak Group) Ramsar area, Alborz Mountains, North Iran. is distinguished especially by short curved strongly falcate pinnae clearly auriculate bases particularly its long, slightly very elongated triangular pinnae, opposite sub position auri...

We studied the modern pollen rain in two different landscapes from Hyrcanian lowland forests up to slopes of Alborz Mountains Gilan province for first time. Pollen traps were installed one year and moss samples collected along altitudinal transects 100 1800 m 2300 elevations. The results counting environmental DNA barcoding (metabarcoding) compared 32 locations. In total, 81 vascular plant spec...

Aim of study: To investigate the impact factors affecting greenhouse environment on energy consumption and productivity.Area Alborz province Iran during period 2018–2020.Material methods: In this study, 18 active units owners in that had necessary standards were identified. Then, upper lower amplitudes variables productivity greenhouses calculated using a type-2 fuzzy neural network, Matlab 201...

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...
