The research variables are: gender (male, female), the academic specialization (science, humanities), the academic stage (2nd, 4th). To achieve the research aims, the researcher adopted Life Quality Scale of (Mensi and Kadhim 2006) which is consist of (56) items in its final figure in five alternatives. The researcher tested the psychometric features of the scale represented by validity and reliability. The scale has been applied on a sample of Baghdad University students that is contained of (240) students equally distributed in the Colleges of Engineering, Science, Arts, and Political sciences.

Show MoreThis work is focused on studying the effect of liquid layer level (height above a target material) on zinc oxide nanoparticles (ZnO and ZnO2) production using liquid-phase pulsed laser ablation (LP-PLA) technique. A plate of Zn metal inside different heights of an aqueous environment of cetyl trimethyl ammonium bromide (CTAB) with molarity (10-3 M) was irradiated with femtosecond pulses. The effect of liquid layer height on the optical properties and structure of ZnO was studied and characterized through UV-visible absorption test at three peaks at 213 nm, 216 nm and 218 nm for three liquid heights 4, 6 and 8 mm respectively. The obtained results of UV–visible spectra test show a blue shift accomp
