This study was intended to investigate the impact of online education on academic performance among university students in Mogadishu Somalia. This study conducted a descriptive research design with a quantitative approach to accomplish research objectives. The study conducted primary data and used a questionnaire as a method of collection. The target population of this study is based on the students among universities in Banadir region. Students with a sample size of 130 respondents. The data was taken from respondents through a questionnaire and the data were analyzed by SPSS version 20 and excel 2010. The specific objectives for the study were to determine the effect of the e-learning system on academic performance, to investigate the effect of class atten dance on academic performance, and satisfaction students' online system on academic performance. Research of this study recommended that the organizations that provide internet service make it easier for the student to access cheap internet and high -speed internet.

Abstract: Samples of LaxSr1-xMnO3 (x = 0.5, 0.55, 0.6, 0.66, and 0.7) were prepared by the citrate-nitrate autocombustion method. The prepared nano-particles were investigated and characterized using X-Ray diffraction (XRD) and Transmission Electron Microscopy (TEM) to confirm the formation of the samples in single phase without any impurities and to calculate the particle size. The magnetic susceptibility χM was measured as a function of temperature and magnetic field intensity. From χM(T) and M(H) the saturation magnetization (Ms), remanent magnetization (Mr) and coercivity (Hc) of the samples were estimated. The correlation among physical properties and the ratio of divalent cation substitution was discussed and reported to shed more light on technological applications of the investigated samples.
