Knowledge on habitat suitability of ecologically important species is central for their conservation management. The occurrence records brown bear (Ursus arctos) in Kurdestan Province Iran and environmental data were compiled to predict the ecological niche this using Maxent distribution algorithm. Satellite imagery Landsat 5 8 1990 2017 was also employed investigate human-induced land degradat...

Dasycladales are relatively abundant in the bedded limestones of the Bidestan and Howz-e Khan members of the Late Triassic Nayband Formation in central Iran. In a locality south of the town of Naybandan (northwest of Dig-e Rostam), several Rhaetian dasycladacean algae were found in thin sections.

introduction iran forms a relatively compact zone of active continental deformation resulted from the northward collision of arabia with eurasia during late cenozoic times, which is continuing to the present-day at a rate of 25 mm/yrs (from gps data). evidences of active tectonic in different parts of iran, has been studied and identified. the arid climate, low rates of erosion, and minimal veg...

Permeability is arguably the most important property in evaluating fluid flow in the reservoir. It is also one of the most difficult parameters to measure in field. One of the main techniques for determining permeability is the application of Nuclear Magnetic Resonance (NMR) logging across the borehole. However, available correlations in literature for estimating permeability from NMR data do n...

    The water crisis in arid and semi-arid regions is a limiting factor for human activities and sustainable agricultural development. One of the new solutions in this field is the construction of underground dams. Underground dams compared to conventional dams that store river water in open reservoirs; block the subsurface flow of water in the cross-section of the river and store it under the ...
