he equatorial ionosphere is a dynamic medium by different processes, for example due to the disturbance of ion and electron densities in the ionosphere, and brought the problem in the communication and navigation system. ...

Ferromagnetism and superconductivity had been thought to be mutually exclusive. Even when superconductivity has been thought as arising from magnetic mediation of paired 'electrons, it was believed that superconductivity ...

The purpose of this thesis work was to analyze the content~ of grade 8 physics textbook prepared by the Amhara Education Bureau in the year 2006. It was conducted realizing the fact that the new education and training ...

Aerosols are minute liquid or solid particles suspended in the atmosphere. Aerosol optical Depth (AOD) and Angstrom Exponent (AE) are significant parameters to study the concentration and size or type of aerosol over an ...

This thesis asserts the effects of solar activity on CPS ionospheric TEC observed at Nazareth station in the year of 2011. For the study, the dual frequency signal from GPS shtellite is recorded at Nazareth (8.568 0 N ...

Ionospheric electron density affects trans-ionospheric radio waves. Estimating elec­ tnm density, therefore, is vital to mitigate the effect of ionosphere OIl radio waves. As a re~ult, different methods have been applied ...

he data collected by the ground based GPS receiver located at Adama (8.57° Nand 39.29° E) have been analyzed to study the temporal variations of the ionosphere in ) the region. We have also investigated the effects of ...

This study investigated the effect of student-centered instruction in improving students' conceptual understanding of wave motion in Mudula secondary and preparatory school found in Mudula town of South Nations, Nationalities ...

Scintillations are the effect of irregular electron density on the propagation of electromagnetic signals through the ionosphere. The scintillating signals change phase unexpectedly and vary rapidlyinamplitude. ...

This work succinctly narrative the longitudinal variability of the horizontal component of earth's magnetic field along equatorial region by using ground base magnetometer data observed at equatorial stations of Guam, ...
