The Variations Of Geomagnetic Energy And Solar Irradiance And Their Impacts On Earth's Upper Atmosphere
The primary energy sources of Earth's upper atmosphere are the solar irradiance and geomagnetic energy including Joule heating and particle precipitation. Various data and models are utilized to investigate the variations ...
First Principles Computational Modeling Of The Surface Properties Of Uranium Dioxide
The interaction of uranium dioxide (UO₂) with environmental elements occurs at its exposed surface and a fundamental understanding of this interaction process begins at the atomic scale. In this regard, atomic scale ...
Phenomenological Studies Of Dark Matter
It is common knowledge that eighty percent of the matter in our Universe consists of a mysterious substance called ``dark matter'' (DM) which has only been detected through its gravitational interactions. The ``Standard ...
Experimental Studies Of Fundamental Aspects Of Auger Emission Process In Cu(100) And Ag(100)
Auger spectra at the low energies are accompanied by large contributions unrelated to the Auger transition. The Auger unrelated contributions can obscure the Auger peak and affect the quantitative analysis of the materials ...
Biological Damage Of UV Radiation In Environments Of F-type Stars
I investigate the general astrobiological significance of F-type main-sequence stars with special consideration to stellar evolutionary aspects due to nuclear evolution. DNA is taken as a proxy for carbon-based macromolecules ...
