This chapter re-examines the early development of the ʻAlawi community and its situation in western Syria in the medieval period in the wider context of what might be termed Islamic provincial history. It starts from the premise that the conventional image of the “Nusayris” has largely been fashioned by elite historical sources whose discourse on nonorthodox groups is a priori negative but which, when read against the grain and compared with other sources, can yield a less essentializing, less conflicting account of the community's development. In particular, the chapter aims to show that the ʻAlawi faith was not the deviant, marginal phenomenon it has retrospectively been made out to be but, on the contrary, constituted, and was treated by the contemporary authorities as, a normal mode of rural religiosity in Syria.

Background: The processes of destruction and crosslinking of macromolecules occur simultaneously under the influence of ultraviolet (UV) radiation in synthetic polymers, dry DNA and their concentrated solutions. Objective: The effect of UV radiation on calf thymus DNA in dilute solutions subjected to UV- irradiation was studied in this work. Method: The calf thymus DNA was studied in dilute solutions using viscometry, absorption spectroscopy and electrophoresis. Results: It was shown, that at a low concentration of DNA in the buffer solution ([DNA] = 85 μg / ml) under the influence of UV radiation, the processes of destruction of macromolecules and an increase in their flexibility predominate, which is accompanied by a gradual decrease in the viscosity of their solution. In addition, due to the low concentration of the solution, intramolecular crosslinking of macromolecules predominates, which also reduces their size and, consequently, the viscosity of the solution. Conclusion: It was concluded, that in dilute DNA solutions, due to the predominance of the processes of intramolecular crosslinking of macromolecules over intermolecular, only constant processes of decreasing the sizes of DNA macromolecules occur. As a result, its solubility remains virtually unchanged during UV irradiation. The described comments are also excellently confirmed by the results of absorption spectroscopy and electrophoresis
