Interferometric Synthetic Aperture Radar (InSAR) capability to detect slow deformation over terrain areas is limited by temporal decorrelation, geometric decorrelation and atmospheric artefacts. Multitemporal InSAR methods such as Persistent Scatterer (PS-InSAR) and Small Baseline Subset (SBAS) have been developed to deal with various aspects of decorrelation and atmospheric problems affecting ...

Well-preserved miospore assemblages are recorded from the Late Ordovician (Katian-Hirnantian), Ghelli Formation in Pelmis-gorge at the north-eastern Alborz Mountain The palynomorphs were extracted from siliciclastic deposits which are well-dated by using of marine palynomorphs (acritarchs and chitinozoans). The encountered miospore assemblages consist of 14 genera (28 species: 26 cryptospores a...

the fauna of the superfamily bombylioidea was studied in alborz province, iran during 2012. two families (bombyliidae and mythicomyiidae), eight genera and ten species were identified, of which two species, exoprospora dispar loew, 1869; parageron lutescens (bezzi, 1925), are new records for the iranian fauna. an identification key for the species of the family mythicomyiidae known from iran is...

Received Accepted Ovalocephalus has a long stratigraphic range and wide geographical distribution in Ordovician peri-Gondwana. Based largely on the well-preserved specimens recently collected from China, all known forms are revised and listed. Phylogenetic analysis was conducted on the genus, involving 10 species. As suggested by the strict consensus tree, evolutional trends of the genus includ...

The genus Belyta Jurine, 1807 (Hymenoptera: Diapriidae) is studied in northern Iran. specimens were collected using Malaise traps the Alborz, Golestan, Gilan, Mazandaran and Qazvin Provinces during 2010–2018. seven species of are recorded from Iran for first time, abrupta Thomson, 1858, B. bicolor 1807, depressa elongata rugosicollis Kieffer, 1909, sanguinolenta Nees, 1834 validicornis 1858. Di...

Subject analysis of the potential of spontaneous combustion in coal layers with analytical and numerical methods has been always considered as a difficult task because of the complexity of the coal behavior and the number of factors influencing it. Empirical methods, due to accounting for certain and specific factors, have not accuracy and efficiency for all positions. The Rock Engineering Syst...


 Located in the Semna?n area (midway between Tehran and Khorasan), town of S?ahmirza?d its neighboring villages are home to speakers S?ahmirza?di, a vernacular sharply differing from other language types spoken but closely related Mazandarani across Alborz range north, along Caspian coast. This article studies S?ahmirza?di phonology, grammar, vocabulary, with look at cross-linguistic infl...
