پر امن معاشرے میں تعلیم کا کردار

Education play main role in modern society and main purpose of education is to create a society characterized by holiness and reconciliation so that society is filled with a spirit of sympathy, sadness and good will. In no time has the usefulness of education and its spirituality been devalued. Education is recognized as a symbol of the greatness the living nations and civilized society.  Educated society reflects patience humble, grateful, fear and the most important habit such as determination and become an integral part of life. Even the educated society is considered to be a true pioneer of courage and human values. Education plays a positive role in empowering the weakest society. On the other hand educated people can think of the happiness and the well-being of humanity due to the light knowledge and their sincere efforts when working in this society so of course this will directly benefit those who are weak and ignorant in the society and the key to maximizing humanity. The light of education should also go to homes that are deprived of wealth and helplessness. It also means abiding by the law showing respect to women and helping the weak. Controlling bad temper and language being polite and following proper etiquette in a gathering is also part of good social behavior. In short good social behavior is living decently, peacefully, and with dignity among others without hurting or disturbing them. Good social behavior helps us live amicably in our society. It promotes good will and understanding among people and cultivates a clean, healthy environment for all citizens

Computer Simulation of Point Defect Twin Boundary Interactions in Face Centred Cubic Metals.

A new method has been established to compute the variants of point defect clusters depending on their symmetry. Results are presented! for close- packed clusters of up to five point defects in cubic crystals. Interesting) relations among the variants of point defect clusters in two and three dimensiqnal lattice structures have been noted. Computer simulation techniques haye been employed to determine the relaxed structures and energies of sortie planar defects using manv-body potentials developed by Ackland et at. (198ir). The structures of some low index twin boundaries, e g. (130), (1j23), (140) and (114) in Copper, are explored 4? to examine their energy configurations. In (140) and (114) twin boundaries local atomic adjustments are made to obtain low interfacial energy. The atomic planes twin interface in all the cases. The interactions of coalesce at the vacancy with (1$0), (123), (140) and (114) boundaries are studied. For single vacancy the maximum binding energy for (123) and (114) boundary is observed when vacancy lies at the plane adjacen: to the interface. The structures and energies of (111), (001) and (110) twist boundaries with different misorientation angles in copper, silver, and investigated as well. It is observed that in-plane translations are flold necessary to establish low energy (110) twist boundary.
