Fabrication of surface reliefs is achieved by raster scanning dry photopolymer films under a focused laser beam. The formation of the structure takes place subsequent to illumination without any chemical treatment or wet processing. Computer-generated optical elements can be recorded quickly, easily, and at low cost. The technology is particularly well suited for rapid prototyping and design pu...

The classical wetting models, such as the Wenzel and Cassie-Baxter have been extensively used to quantify wettability of laser-textured surfaces. However, these models do not provide any description corresponding droplet dynamics. In this work, we propose a detailed continuum-level modelling study dynamics water on Ti-6Al-4V alloy. calculations are performed for flat surfaces with various relie...

jondishapour school was the first center of cultural transmission in the world among various civilizations like the greek, syriac, hindi, chinese and roman formed by permissive policies of khosro anushirvan in iran. the idea that iranian knowledge can be flourished with the help of progress made in science in different cultures was, for the first time, suggested by khosro anushirvan and his com...

Two distinctive features of Sasanian bridges are their designation as weir-bridges and function in the facilitation irrigation. This has often been used to emphasise a specific administrative centralisation. The author stresses continuity investments infrastructures, from Arsacids Islamic period via Sasanians. It is presented that members elite governing classes well private entrepreneurs provi...

In the site of Gird-i Bazar in Sulaymaniyah province, a Sasanian cemetery was found installed over, and partly damaging, older Iron Age structures. Although Zoroastrians notoriously exposed bodies then placed bones into astodans, inhumations are not uncommon such multi-cultural empire. After mentioning cemeteries same region underlining presence large Christian community Adiabene, author descri...
