Models of Long-Period Superstructures

Ab initio study of long-period superstructures in close-packed A3B compounds.

FIM ATOM PROBE INVESTIGATION OF LONG PERIOD SUPERSTRUCTURES IN Cu3 xPd

FIM atom-probe techniques have been used in order to investigate concentration modulations related to (001) APB's in Cu3 ,Pd. Layer by layer analysis of (001) superstructure planes of a long-period single crystal (20.5 % Pd) exhibits LRO modulations with correlation lengths oscillating between 6 and 7 doO,. The average wavelength (6.5 dO0,) is in good agreement with the mean size of one-dimensi...

Long Period Seismology on Europa: I. Physically Consistent Interior Models

In order to examine the potential of seismology to determine the interior structure and properties of Europa, it is essential to calculate seismic velocities and attenuation for the range of plausible interiors. We calculate a range of models for the physical structure of Europa, as constrained by the satellite’s composition, mass, and moment of inertia. We assume a water-ice shell, a pyrolitic...

evaluation of sadr eminence in safavid period

چکیده: یکی از دوره های مهم تاریخی ایران به لحاظ تأمین استقلال ملی مذهبی و حتی تأثیر آن بر فرهنگ و مذهب ایرانیان، دوره صفویه است. رسمیت دادن و رواج مذهب شیعه توسط شاه اسماعیل اول، یکی از مهمترین اقدامات این دولت محسوب می شود. بنابراین برای اجرای این سیاست، وی منصب صدارت را به عنوان منصبی مذهبی- حکو متی ایجاد کرد .این منصب از دوره ی تیموریان ایجاد شده بود ولی در اواخر این دوره اهمیت بیشتری یافت...
