Albert Reimer 
Horizons in World Physics. Volume 306 

This monograph includes five chapters that present recent advancements in physics from authors around the world. Chapter One explores how theories of physics have influenced the international relations discipline and considers what international relations theorists can learn from physics in the future. Chapter Two presents various approaches for determining the electromagnetic field in fixed and steadily rotating charged bodies in the form of a cylinder and a sphere. Chapter Three deals with the synthesis and emission properties of multiple rare earth doped white light-emitting single-phase perovskites. Chapter Four discusses two theoretical methods used to explore the kinetic behavior of the multi-step process of batch protein crystallization. Finally, Chapter Five proposes a modified version of the dual copy idea, which states that the two theories of perturbative gluon-gluon and graviton-graviton scattering amplitudes are dual descriptions of the same physics, in which an exact relation between classical, spherically symmetric metrics and gauge field static potentials is established.
