Space plasmas are frequently described by kappa distributions. Non-extensive statistical mechanics involves the maximization of the Tsallis entropic form under the constraints of canonical ensemble, considering also a dyadic formalism between the ordinary... see more

This paper presents our theoretical investigations on the structural variations of dust acoustic solitary waves (DASWs) in inhomogeneous unmagnetized plasmas. To study the structural variations of DASWs, we have considered collisionless, hot isothermal, a... see more

Homogeneous discharges are easily obtained at atmospheric pressure in dielectric barrier discharges (DBD) for some noble gases. To predict the discharge electrical comportment, one-dimensional fluid model of typical DBD is presented and applied to Helium ... see more

The main objective of the COST 296 Action «Mitigation of Ionospheric Effects on Radio Systems» is the establishment/ improvement of ionospheric services by coordinating the development of specific algorithms, models, and tools capable of operating in a ne... see more

Two regional GPS receiver networks from the Ordnance Survey U.K.(OS)and the Italian Space Agency (ASI) have been used for monitoring mid-latitude Total Electron Content (TEC)during quiet and disturbed ionospheric conditions in the current solar cycle.A fe... see more

Nonlinear electrostatic shock structures in dissipative magneto-rotating electron-positron-ion (e-p-i) plasmas with warm ions, non-thermal electrons and positrons following the q-nonextensive velocity distribution are investigated. The Korteweg de Vries B... see more

In quantum field theory, many phenomena are characterized by a condensed structure of their vacua. Such a structure is responsible of a non trivial vacuum energy. Here we analyze disparate systems and we show that the thermal vacuum state for hot plasmas,... see more

Migration is associated with the search for a more permissive environment. By linking Paris as a place of attachment, the author sees that Paris in this case can be indicated as the “home” for Indonesian gays. The feeling of “full gay” is a feeling that t... see more

The beauty and the regularity of the heavenly bodies have fascinated the mankind from time immemorial. Perceptions of space and celestial bodies in ancient India derive from mainly two sources, which often overlap, namely mythological/religious explanatio... see more
