according to the holy qur'an, human life is intermingled with trials, having a mutual relationship with man's perfection and elevation. as objective models of divine trials, prophets are chosen and reported intelligently in the qur'an. the central issue in this research is to draw a revealed pattern of the trial of prophets and analyze its components, emphasizing on the story of ...

T he problem of fairly dividing a divisible good, such as cake or land, between two people probably goes back to the dawn of civilization. The first mention we know of in Western literature of the well-known procedure, “I cut, you choose,” occurs in the Hebrew Bible, wherein Abraham and Lot divide the land that lies before them, with Abraham obtaining Canaan and Lot obtaining Jordan (Genesis 13...

In this paper we generalize a result by Rubin and Ungar on Hamiltonian systems containing a strong constraining potential to Langevin dynamics. Such highly oscillatory systems arise, for example, in the context of molecular dynamics. We derive constrained equations of motion for the slowly varying solution components. This includes in particular the derivation of a correcting force-term that st...
