The radioactivity concentrations of Naturally Occurring Radioactive Materials (NORM) i.e., 226Ra, 232Th, and 4 K in various chemical fertilizers being used in the agricultural soil of Pakistan were determined utilizing gamma spectrometry by employing

The generalized expression for the Bernstein waves in the nonrelativistic limit is analyzed for pair ion plasma with the contribution of electrons. The effect of temperature and mass asymmetry on the propagation of the Bernstein waves is studied in d
We derive the nonlinear equations governing the dynamics of three-dimensional (3D) disturbances in a nonuniform rotating self-gravitating fluid under the assumption that the characteristic frequencies of disturbances are small compared to the rotatio

We have investigated linear and nonlinear dynamics of ion-temperature-gradient driven drift mode for Maxwellian and non Maxwellian pair-ion plasma embedded in an inhomogeneous magnetic field having gradients in ion's temperature and number density. L

Propagation of an electrostatic surface wave in a thin degenerate Fermi plasma film in the presence of constant external magnetic field is studied here. Dispersion relations for the symmetric and anti-symmetric modes have been derived and studied qua
Following the idea of three wave resonant interactions of lower hybrid waves it is shown that quantum -modified lower hybrid (QLH) wave in electron positron ion plasma with spatial dispersion can decay into another QLH wave ( where electron and posit

The nonlinear wave structures of baryon acoustic waves in ambiplasma consisting of baryons (positive and negative ions), and nonextensive leptons (electrons and positrons) are theoretically investigated by employing a pseudo-potential approach, which

Dust acoustic (DA) waves evolving into shocklets are investigated in the comet Halley plasma system relaxing to Maxwellian, Kappa, and Cairns distributions. Here, dynamics of dust is described by the fully nonlinear continuity and momentum equations.
Using Boltzmann Vlasov kinetic model with the flat-top non-Maxwellian distributed electrons and ions, a velocity power law energetic tail, known as the generalized r, q distribution, a current-less electrostatic instability namely ion acoustic which
