The Ni(II) and Zn(II) complexes with phenylpyridylformamidine (PhPyF) ligand, [Ni(PhPyF)Cl2] and [Zn(PhPyF)Cl2], have been prepared and investigated using different chemical techniques such as elemental analysis, molar conductance, FT-IR, UV-vis spectra and magnetic moment. The obtained chemical analysis data showed the formation of 1:1 (metal: ligand) ratio. The square planar and tetrahedral g...

mri workers are occupationally exposed to static and time-varying gradient magnetic fields.  while the 24-hour time-averaged exposure to static magnetic fields is about a few mt, the maximum static field strength can be as high as 500 mt during patient set up. over the past several years, our lab has performed extensive experiments on the health effects of exposure of animal models and humans t...

مدل سازی پیش بینی پراکنش گونه های گیاهی بر اساس ارتباط بین داده های حضور یک گونه و متغیرهای محیطی تعریف می شود. امروزه در عرصه اکولوژی گیاهی، تهیه نقشه های پیش بینی پراکنش گونه ای یا تیپ های گیاهی با توسعه روش های آماری و سیستم های اطلاعات جغرافیایی، مورد توجه ویژه قرار گرفته است. به منظور مدل سازی رویشگاه بالقوه ریواس (rheum ribes l.) در استان اصفهان از دو روش مدل سازی حداکثر آنتروپی و ژنتیک ا...
