We examine the behavior of F-rationality under flat homomorphisms with geometrically F-rational fibres. The goal is to prove that if R ยช S is a homomorphism with geometrically F-rational fibres and R is an F-rational ring, then S is an F-rational ring. We prove a stronger version of this under a mil

In the early days of electron microscopy polystyrene latex particles were used as magnification standards. But in contrast to optical diffraction grating replicas made with carbon or SiO with precise line spacings resistant to electron irradiation, the latex spheres undergo changes, and conflicting
When the dimensions decrease to nano-scale, many essential phenomena appear which are not important at macro scales. In this paper, two effects of these sub-micron phenomena are demonstrated and considered for simulation of pull-in instability of beam-type nano-actuator. The first phenomenon that be
