High resolution stratigraphy and extinction patterns of the Ammonoidea at the Permian-Triassic boundary of NW Iran
The classical Permian-Triassic (P-Tr) boundary sections in the vicinity of Julfa (NW Iran) have high potential for the study of the end-Paleozoic extinction event. The lithostratigraphic record of the P-Tr boundary beds in the Julfa area is rather...

In Vitro Propagation of Colutea gifana, a Rare and Endangered Species in Iran
of the plantlets were successfully acclimatized to ex vitro conditions, exhibiting normal development. These plantlets can be used to replenish declining populations in the wild to conserve C.gifana from extinction and also for further studies about this species....

Isolated bridgeless converter for welding power supply with improved power quality
Pre–mass extinction decline of latest Permian ammonoids
The devastating end-Permian mass extinction is widely considered to have been caused by large-scale and rapid greenhouse gas release by Siberian magmatism. Although the proximate extinction mechanisms are disputed, there is widespread agreement...
The role of microbial anaerobic respiration in the end-Permian mass extinction
Changes in plankton productivity have been connected with the end-Permian mass extinction. A box-model – proxy data comparison suggests that an increase of microbial sulfate reduction (MSR) can explain excursions in δ34SCAS and δ18OCAS...
