Opis:
This essay discusses the importance of Ctesiphon in the historical and literary tradition of Sasanian and Post-Sasanian Iran. It is proposed that there was a significant buildup of the Ctesiphon’s defenses in the third century that it made its conquest by the Roman Empire impossible and its gave it an aura of impregnability. By the last Sasanian period the city was not only inhabited by Iranian speaking people and a capital, but it also became part of Iranian lore and tradition, tied to mythical Iranian culture-heroes and kings. Even with the fall of the Sasanian Empire, in Arabic and Persian poetry the grandeur and memory of Ctesiphon was preserved as part of memory of the great empires of the past.

Opis:
Propulsion designers all over the world are exploring the possibility of achieving higher performance by enhancing the energy of solid propellants. This can be achieved by replacing non-energetic ingredients with energetic ones or by replacing low density ingredients, particularly binders, with higher density ones, without affecting the processibility and ageing characteristics. The same has been attempted by using nitroglycerine (NG) and butanetriol trinitrate (BTTN) as plasticizers in propellant compositions. In the present study, NG and BTTN have been used in different plasticizer to polymer ratios (Pl/Po) and various parameters of each composition have been theoretically predicted. Three propellant compositions plasticized with NG, BTTN and a 1:1 combination of NG and BTTN, have been processed and analyzed for targeted properties. From the theoretical data, it was observed that there is a negligible increase in density impulse beyond a Pl/Po ratio of 2, apart from the higher density and calorimetric values of the NG-plasticized propellant; these plasticizers have a significant effect on the ballistic and mechanical properties. Another observation was that the elongation of BTTN and NG/BTTN (1:1) plasticized propellants is significantly higher at a low crosshead rate than NG-plasticized propellant, implying that the two former propellants have higher strain capabilities at low temperatures and can be used for missiles having long term low temperature storage requirements. Thermal decomposition studies have been carried out by DSC, and for each composition 5 distinct peaks were observed.
