A consideration of the theory of exceptions in makki and madani chapters
By exceptional verses is meant makki verse in madani chapter and madani verse in makki chapter. There cannot be found any reference to this theory in sources in first and second century of Hijri. In the third, however, it was found on a small scale; in the next two centuries, the number of the cases increased gradually and in the sixth and seventh it came to its ultimate point.

متن کاملEpidemiologic transition theory exceptions
Abdel Omran’s 1971 theory of epidemiological transition is an attempt to account for the extraordinary advances in health care made in industrialized countries since the 18 century. According to Omran, all societies experience three "ages" in the process of modernization: the "age of pestilence and famine", during which mortality is high and fluctuating, with an average life expectancy under 30...
متن کاملA Density Functional Theory Study of Structure of Phosphonic Acid
The molecular structure of the stable conformation of phosphonic acid in gas phase has beencomputed by employing complete geometry optimization in Density Functional Theory(DFT) methods. The methods used for calculations are B3LYP, BP86 and B3PW91 that havebeen studied in two series of basis sets: D95** and 6-31+G(d,p) for hydrogen and oxygenatoms; LANL2DZ for phosphorus. Bond lengths and angle...
متن کاملA Density Functional Theory Study of Boron Nitride Nano-Ribbons
The electronic and structural properties of pristine and carbon doped (C-doped) boron nitride nano-ribbons(BNNRs) have been studied employing density functional theory (DFT) calculations. Total energies, gapenergies, dipole moments, and quadrupole coupling constants (qcc) have been calculated in the optimizedstructures of the investigated BNNRs. The results indicated that the stability and gap ...
متن کاملapplying transitivity theory to gender analysis of efl textbook: : a comparative study.
efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...
