تکفیری جماعت داعش: افکارو اثرات: تجزیاتی مطالعہ

Since the past few years, muslims all over the world are being brutally accused of severe extremism. Many muslims now a days condemn terrorism and extremism and are not willing to connect these terms with the religion Islam. However there are a few who are in favour of these things. Terrorism is basically caused by a number of different acts of brutality. Its actually a chain reaction caused by the conspiracies against Islam, double standards of different super powers and injustice to the convicted and oppressed. Killings of the innocent and unarmed in the name of aggression is some thing which is totally against the Islamic teachings. Things become more complicated and dangerous when such acts of vandalism are done in the name of religion. Although many goals of ISIS are Islam based, however these very goals are achieved through non-Islamic ways. They feel no shame and go against all the ethics and moral values to reach their goals. Hence causing much more damage to their own muslim fellows. Even the cemetries are no more safe. They kill their opponents in the worst possible way and disrespect the dead bodies by kicking and hanging them to the trees. If this situation persists, it is inevitable that ISIS might replace the Halaku Khan and Genghiz Khan is brutality.

Drift Effects on Plasma Waves

The full kinetic dispersion relation for the Geodesic acoustic modes (GAMs) including diamagnetic effects due to inhomogeneous plasma density and temperature is derived by using the drift kinetic theory. The fluid model including the effects of ion parallel viscosity (pressure anisotropy) is also presented that allows to recover exactly the adiabatic index obtained in kinetic theory. We show that diamagnetic effects lead to the positive up-shift of the GAM frequency and appearance of the second (lower frequency) branch related to the drift frequency. The latter is a result of modification of the degenerate (zero frequency) zonal flow branch which acquires a finite frequency or becomes unstable in regions of high temperature gradients. By using the full electromagnetic drift kinetic equations for electrons and ions, the general dispersion relation for geodesic acoustic modes (GAMs) is derived incorporating the electromagnetic effects. It is shown that m=1 harmonic of the GAM mode has a finite electromagnetic component. The electromagnetic corrections appear for finite values of the radial wave numbers and modify the GAM frequency. The effects of plasma pressure βe, the safety factor q and the temperature ratio τ on GAM dispersion are analyzed. Using the quantum hydrodynamical model of plasmas, the stability analysis of self-gravitational electrostatic drift waves for a streaming non-uniform quantum dusty magneto-plasma is presented. For two different frequency domains i.e., Ω0d<<ω<Ω0i (unmagnetized dust) and ω<< Ω0d < Ω0i (magnetized dust), we simplify the general dispersion relation for self-gravitational electrostatic drift waves which incorporates the effects of density inhomogeneity ∇n0α, streaming velocity v0α due to magnetic field inhomogeneity ∇B0, Bohm potential and the Fermi degenerate pressure. For the unmagnetized case, the drift waves may become unstable under appropriate conditions giving rise to Jeans instability. The modified threshold condition is also determined for instability by using the intersection method for solving the cubic equation. We note that the inhomogeneity in magnetic field (equilibrium density) through streaming velocity (diamagnetic drift velocity) suppress the Jeans instability depending upon the characteristic scale length of these inhomogeneities. On the other hand, the dust-lower- hybrid wave and the quantum mechanical effects of electrons tend to reduce the growth rate as expected. A number of special cases are also discussed.
