ISO mid-infrared absorption data helps to distinguish between radiative and collisional pumping mechanisms in 1612MHz OH masers in various environments. Archive data of OH absorption at 34.6 and 53.3 μm shows different behavior and different pumping rates for different types of maser sources. 1. Mid-Infrared absorption in 1612MHz OH masers Mid-infrared spectroscopy by the Infrared Space Observa...

gallium extraction from jajarm bayer process liquor (jajarm, iran) was investigated using microemulsions. also the behavior of aluminum was studied as an impurity. kelex100 (4-ethyl, 1-methyl, 7-octyl, 8-hydroxyquinoleine), iso-decanol and n-butanol, and kerosene were used as the surfactant, co-surfactant, and oil phase, respectively. ternary phase diagrams were produced using various co-surfac...

Background & Aims: Nowadays, new attitudes of clients, patients and students toward the quality of health care services, have led to unifying different systems in educational centers, which has been recognized as quality management system. The ISO standard series have created systems that integrate intra and inter organization processes to improve the quality of health services. The aim of the ...

DFT calculations were applied to evaluate the electronic and magnetic properties of zigzag BC2Nnanotubes based on the 13C, 15N, and 11B NMR parameters and natural charge analysis. Weconsidered three types of zigzag nanotubes, ZZ-1, ZZ-2, and ZZ-3 (n, 0) with n = 8, 12, and 14. Theobtained results indicated the divisions of the electrostatic environments around C nuclei into a fewlayers, consist...

BACKGROUND Tissue Doppler imaging is used routinely to quantify both left and right ventricular function. However, normal reference values of echocardiography parameters of the right ventricle in Iranian population are still unknown. OBJECTIVES Accordingly, we conducted a study to determine the normal values of echocardiography parameters of right ventricular function in a healthy Iranian pop...
