Many applications of carbon nanotubes require their chemical functionalization. Both covalent and supramolecular approaches have been extensively investigated. A less trodden path is the combination of both covalent and noncovalent chemistries, where the formation of covalent bonds triggers a particularly stable noncovalent interaction with the nanotubes. We describe a series of naphthalene dii...

the first season of survey at qeshm, carried out during the winter of 2006, resulted in the identification of nine sites from the parthian and sasanian periods. the surface pottery from these sites suggests their trade and cultural relations with contemporary sites in the southern persian gulf and other areas. for instance, the parthian and sasanian glazed types in qeshm island are closely re...

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...

What is it that shapes mathematical arguments into proofs that are intelligible to us, and what is it that allows us to find proofs efficiently? — This is the informal question I intend to address by investigating, on the one hand, the abstract ways of the axiomatic method in modern mathematics and, on the other hand, the concrete ways of proof construction suggested by modern proof theory. The...

the geographic location of the elamite terrain which lies in parts of today's khuzestan caused a middle-man-role for this region situated in between water-ways leading to the head of the persian gulf and iranian plateau and mesopotamia. in addition to the fact that this territory, possessing several rivers, was very fertile, the reality that of one of the most important iranian trade-route...
