This monograph is the fIrst book exclusively devoted to Dusty and Dirty from a unifIed Electrohydrodynamical point of view, incorporating new Plasmas concepts of Electric Cusp-Reconnection and Generalized Critical Ionization Velocities, based on a survey stimulated from a series of International Wo- shops/Symposia on Plasmas in Space and in the Laboratory held in Tokyo since 1980, and from associations with a number of Universities and Institutions which offered me opportunities to do specifIc research. For example, the subjects of Mirrors and Cusps, Critical Velocities, Double Layers or Dipoles, and Quadrupoles in this monograph were initiated by the fIrst International Workshop on Relation between Laboratory and Space Plasmas held in Tokyo in 1980 which was well received, in this connection in particular thankfully by the late Professor Hannes Alfven with encouraging communica tions, inspiring me to studies of critical velocities, electrical version offield line merging-reconnection, and Unconventional Plasmas.
Although the subject of this monograph was partly included also in topics at the URSI Workshop on Nonlinear and Environmental Electromagnetics in 1984, at the second Wo- shop on Relation between Laboratory and Space Plasmas in 1986, and at the URSI Symposium on Environmental and Space Electromagnetics in 1989, the main subject: Dusty and Dirty Plasmas and EHD (electrohydrodynamics) was discussed exclusively at the later Symposium in 1992, resulting in the fIrst monograph, Dusty and Dirty Plasmas with Noise and Chaos in Space and in the Laboratory in this fIeld for which Professor John E.
