this paper presents the current activities on radiation protection in iran. according to the atomic energy organization law of iran the radiological safety is ascribed to the atomic energy organization of iran (a e o i) and the radiation protection department (r p d) is the responsible organ within aeoi. r p d since it's establishment in 1975, with the aim to ensure the protection of man and hi...

Late Embryogenesis Abundant Proteins (LEAPs) are ubiquitous proteins expected to play major roles in desiccation tolerance. Little is known about their structure - function relationships because of the scarcity of 3-D structures for LEAPs. The previous building of LEAPdb, a database dedicated to LEAPs from plants and other organisms, led to the classification of 710 LEAPs into 12 non-overlappin...

It is demonstrated that the addition of organo-modified Na-bentonite (OMB) particles to Portland cement mortar can promote its physical and mechanical properties. A series of experimental works on some important physico-mechanical properties of Portland cement mortars mixed with various dosages of hydrophobic OMB were performed. The obtained results confirm that the OMB provides a dense packing...

The physico-chemical properties of polyphenyleneesterformaloxymate (PEFO) and polyphenyleneetherarylateoxymate (PEAO) have been studied. It has established that the synthesized PEFO PEAO are resistant to aggressive media, good electrical insulators, high thermal stability dielectric characteristics.
