شرعی نقطہ نظر سے عقل اور اس كی حدود كار تحقیقی جائزہ

The meaning of word "Din" are it applied to all the faith, worship and also cov ers that complete code of life which the Holy Prophet (S. A. VV) gave to ultima. Almighty, Allah has given a special and superior status to the human beings and has bestowed upon the human beings the quest for knowledge. Of course, knowledge is the power which enables the human beings to distinguish clearly between what is good or bad. But other words this is the human wisdom which the creator of this world has bestowed upon the human beings. So it is quite clear that the entire system of faith and worship which Almighty Allah has sent to the human beings through the revelation over the Holy Prophet is exactly according to the common mind and intellect. Since there are certain limitations to the common mind and it cannot go beyond these limitations. This research paper present on investigation of these limits form Sharia point of view.

Beltrami States in Three Component Plasmas

A static and stationary relaxed state of a single fluid MHD plasma appears as a consequence of the minimization of magnetic energy while the magnetic helicity remains conserved. The relaxed state is known as Beltrami state and represented by eigenvalue equation of the curl operator. The Beltrami state is a force-free equilibrium state and characterized by a single scale parameter. There exists no pressure gradient in ideal MHD self-organized state.On the other hand, selforganized states of multi component plasmas composed of multi Beltrami states are characterized by strong flow and pressure gradients which are the important features of practical plasmas found in laboratory and space environments. The self-organized states of multi component plasmas are investigated and analyzed. It is shown that self-organized state of electronegative dusty plasma comprising of one positive ion, two negative ions and immobile heavy dust grains can be cast as a superposition of three Beltrami states characterized by three scale parameters. This state is called as Triple Beltrami state and has a wide range of solutions covering paramagnetic as well as diamagnetic self-organized states. The relaxed equilibrium state of three component plasmas is found to be composed of four Beltrami states when all the inertial and non-inertial forces are taken into account. Two of the components constitute a pair while other one is taken to be a singly ionized positive ion. The self-organized state is called as Quadruple Beltrami state and governed by four eigenvalues. It is found that density of ions plays a significant role in the formation of relaxed structures. It is also shown that the relaxed state of three component plasmas can be cast in terms of double Beltrami state which is the superposition of two Beltrami states. The loss of equilibrium in a slowly varying double Beltrami state is investigated by changing control parameter.The equilibrium state is analyzed to observe the effects of magnetic helicity, generalized helicity, ratio of magnetic field to positron flow, density of components and energy of the system. The critical values of energy and control parameter are derived and the results are applied to model the eruptive events occurring in solar coronal loops.
