روند توسعه شوری و تخریب اراضی کشاورزی در منطقه شمسآباد استان قم
Salinization and alkalization are considered spatiotemporal dynamic soil degradation processes. In order to investigate the effects of agricultural activities on land degradation and soil salinity, Shamsabad area in Qom province was selected. Aerial photos (1955) and satellite images (1990-2002) were used to examine the changes in land use. Soil samples were collected from 25 locations in the s...

متن کاملA Comparative Study of Neuroprotective Effects of Human Adipose and Dental Pulp Derived Stem Cells on Hypoxic SH-SY5Y Cells Exposed to CoCl2
Background and purpose: Recent studies have demonstrated the promising effects of mesenchymal stem cells (MSCs) in some neurodegenerative diseases and proved their neuroprotective effects. But, the detailed pathways and the ability of MSCs from various sources has not been fully investigated. Materials and methods: Here, we isolated MSCs from two sources; adipose tissue and dental pulp, and co...
متن کاملOhmic Contact of Cu/Mo and Cu/Ti Thin Layers on Multi-Crystalline Silicon Substrates
Cu-Mo and Cu-Ti contact structures were fabricated on multi-crystalline silicon substrates to provide a low resistance ohmic contact. Deposition steps are done in an excellent vacuum chamber by means of electron beam evaporation and samples are then annealed for the realization of an efficient alloy layer. The effects of process parameters such as film thickness, annealing duration and temp...
