اسلامی مملکت کے بین الاقوامی تعلقات عصرحاضر کے تناظر میں

Islam where considers the superiority of law, provision of justice and equity, building and purification of civilization and emphasis on the welfare of society, there ensures the first priority to humanity, peace and prosperity in the external relations. Islamic state keeps relations on the basis of equality with the world and non-Muslim citizens living within the state. On this belief and ideology Islam invites the world to set together. Islam on these principles of Islamic ideology and belief sets the foundation of collectiveness. On this principle the whole philosophy of life and living system are embraced, and the same Islamic law is the foundation of nations, on this behalf the Islamic state organized the relation with other states. In this way Islamic state on these principles keep relations with other states and within the state relations between Muslim and non-Muslim citizens on the basis of brotherhoods, equality, mercy and the principles of dignity of human being. Along with peace Islam set the principles of war which comprise ethical and prison limitations, duties and ethics amongst warrior, difference between the rights of fighters and non-fighters, treatment with pact holders and prisoners, and specified the way of better treatment with the defeated nations. He thought the manners of war to bloody man who consider everything right during the war. Islam lays great stress on equality, social justice, brotherhood and peace not only in state but across the boarders too. In this article a deep study is done to explain the relations of an Islamic state with other states. Islamic foreign policy emphasizes on the principles of equality among all the human beings and all the races and nations. Islam builds international relation on humanitarian basis.

Study of Potentials in Dense Plasmas.

This doctoral thesis is primarily comprised on the analytical and numerical analysis of the electrostatic dynamic potential associated with a moving test particle in the three disciplines of quantum plasmas namely semi-conductors, astrophysical dusty and relativistic quantum plasmas in the presence of homogenous magnetic field. The study of four aspects of electrostatic potential in quantum plasmas is presented based on the published work. A qualitative analysis of dispersive properties in homogeneous magnetized plasmas is done with fluid approach known as Quantum Hydrodynamic model. Above all, wake potential is studied in the semi-conductor quantum plasmas where an external source of electron beam is taken for exciting the plasma wave. Next, the dense quantum dusty plasma system is taken for the study of wake potential taking into account the quantum effects exhibited by the Fermi pressure, tunneling and exchange-correlation potential of the Fermi particles. Afterwards, the relativistic quantum plasma system is taken for the study of interesting characteristics of wake potential where tunneling potential is ignored in the comparison of Fermi pressure. The behavior of the linear potential is observed similar in the non relativistic plasma either for semiconductor or dusty plasma with a natural difference of higher density. While in relativistic quantum plasma, a subsonic potential is noticed contrary to the supersonic potential existing in non-relativistic plasmas. At the end, linear and KdV type nonlinear cases are studied at very high magnetic field taking into account the Landau quantization of magnetic field. The structural characteristics of the potential pulse and of the associated electric field strongly depend on the magnetic field, in addition to the quantum parameter H= ħ??? 2????? .
