Gomberoff, L. (1995)The linear and nonlinear theory of circularly-polarized Alfvdn and ion-cyclotron waves in multicomponent plasmas is reviewed. It is shown that minor heavy- ion components play an important role in the dispersive properties ...
-
Gomberoff, L.; Hoyos, J. (2005)This paper studies the effect of nonlinear left-hand polarized waves supported by a proton beam on the linear circularly polarized instabilities driven by the same beam. It shows that the nonlinear wave can either stabilize ...
-
Gomberoff, L.; Vega Vega, Luis Felipe (1989)Electromagnetic ion cyclotron waves below the proton gyrofrequency in multicomponent plasmas have been extensively studied in recent years. However, it has recently been suggested that an often used analytical approach ...
-
Gomberoff, L.; Vega, P. (1990)We consider electrostatic instabilities in a plasma composed of an ion beam moving in a stationary background of electrons and ions. Analytical expressions for the ion-acoustic and ion-ion acoustic instabilities are ...
-
Gomberoff, L. (1992)The role of electrostatic ion-beam instabilities in the generation of the broadband electrostatic noise in the earth’s magnetotail and in electrostatic bursts in comets is discussed. The theory of electromagnetic ion-cyclotron ...

Ion cyclotron instability triggered by drifting minor ion species: Cascade effect and exact results Gomberoff, L.; Morales Muñoz, Víctor; Valdivia Hepp, Juan (2004)On the basis of bi-Maxwellian velocity distribution functions it has been recently shown that the combined effect of heavy ion thermal anisotropy and drift velocity can trigger ion-cyclotron instabilities beyond the ...

Valdivia Hepp, Juan; Rogan Castillo, José; Muñoz Gálvez, Víctor; Gomberoff, L.; Klimas, A.; Vassiliadis, D.; Uritsky, V.; Sharma, S.; Toledo Cabrera, Benjamín; Wastavino, L. (PERGAMON-ELSEVIER SCIENCE LTD, 2005-11)Copper was removed from an acidic mine drainage (AMD) using a liquid emulsion membrane contactor. The acidic drainage was a harmful natural acidic solution generated by bioleaching and chemical leaching of copper and iron ...

Gomberoff, L. (Bentham open, 2008-11-26)Finite amplitude Alfvén-cyclotron waves are believed to play an important role in coronal heating and nonthermal properties of velocity distribution functions. These effects are thought to be due to parametrically ...
-
Gomberoff, L. (2007)It is shown that in a plasma composed by electrons, a proton core, and a proton beam propagating along an external magnetic field, finite amplitude left-hand polarized waves propagating backward relative to the beam direction ...

Gomberoff, L. (1984)It is shown that the combined effect of resistivity and thermal conductivity is responsible for the existence of marginal stationary modes in a cylindrical current-carrying plasma, under the influence of a shearless magnetic ...
