in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...

Introduction: Extensive research suggests a common hypothesis regarding the protective role of total high-density lipoprotein-cholesterol (HDL-C) against cardiovascular disease (CVD). This hypothesis indicates an inverse relationship between CVD and high HDL-C levels. Various mechanisms, such as reverse cholesterol transport, besides anti-inflammatory and antioxidant functions, indicate HDL-C a...

Basic physical principles of nuclear magnetic resonance imaging (N.M.R.I), a nonionizing medical imaging technique, are described. Principles of NMRI with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. T1 and T2 and spin density (S.D.) factors and different image construction techniques based on their different combinations is discu...

Background and Objective: Although many helpful procedures are used in pathology for the prognosis of aggressive behavior of lesions, but their morphometric values were not detected. The purpose of  the  present  study  was  to  detect  and  compare the morphometric characteristics  of  KCOT  and  dentigerous  cyst and to determine whether morphometric evaluation is a valuable and helpful metho...
