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 ...
The present work investigates an appropriate way to calculate the 1700 atomic density changes in the reactor operations. To automate this procedure, a computer program has been designed by C#. This program suggests a way to solve this problem which is based on the solution system of differential equations (Bitman) that it is designed according to Runge-Kutta Fehlberg method. The designed softwa...
High-Density Lipoprotein Measurement Methods: From Precipitation to Nuclear Magnetic Resonance (NMR)
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: for xenograft models of triple-negative breast cancer (tnbc) to be valuable in development of molecularly-targeted drugs, careful characterization is essential to their validation. the present study aimed to validate the tnbc xenograft model with a specific focus on angiogenesis. methods : twelve tnbc xenograft tumors and 12 human breast cancer tumors (htnbc) were included in this s...
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...
