dendrimer synthesis strategies now provide virtual control of macromolecular nanostructures as a function of size and surface/interior functionality. these strategies involve the covalent assembly of hierarchical components reactive monomers , branch cells or dendron’s around atomic or molecular cores according to divergent/convergent dendrite branching principles.combinon of two or more dendri...

the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...

The sowthwest of Sorkh kuh prospecting area is located in 120 km SW of Birjand city, western Lut Block. Geology of this area comprising andesitic and basaltic volcanic rocks, which have intruded by intrusive rocks such as hornblende diorite, hornblende tonalite, and biotite monzonite caused extensively alteration and mineralization. Based on remote sensing, field survey, petrography, and XRD, m...

‏‎translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...

The Hatamabad prospect area is located in northeast of Qaen, South Khorasan Province and in northeast of Lut block. The geology of area consists of volcanic rocks with basalt- andesite composition and sedimentary sequences (mudstone, limestone, and conglomerate) with Paleocene-Eocene age that monzodioritic dikes were intruded in them. Monzodioritic dikes have high-k calc-alkaline and metalumino...

in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...

The study area (Kalateh-No) is located in NW of Gonabad city in Khorasan Razavi Province. This area is located in geotectonic Lut Block zone. The rock types are mainly of volcanic and subvolcanics. The most important alteration zones are silisification, propylitic, argillic, serisitic and quartz-serisit-pyrite. The mineralizations have formed by intrusion of hydrothermal fluids of monzodiorite ...

abstract when in administrative law the matter of administrative offences are raised, these offences would have legal nature if they are force able, some of these offences are related to administrative law, where as some other pelts are common in civil or penal law. the current research intends not only to consider the concept and foundation of administrative execution rules but also compares...
