This book presents original research results on the leading edge of physics. Each article has been carefully selected in an attempt to present substantial research results across a broad spectrum. Topics presented in this compilation include the production of isomers by spallation and the consequences for nuclear science; solar flare numerical magnetohydrodynamic simulation and solar flare models; X and Gamma ray interactions with soft contact lenses; visible light therapy research and the structure and development of barrier discharges at atmospheric pressure.
