When the railways were nationalized between 1906 and 1907, the skeleton of the nationwide trunk rail network was nearly completed, as mandated in the Railway Construction Act of 1892. At the end of 1907, nationalized railway lines in operation totalled 7,165 km. Construction continued and 2,677 km of line were added by the end of 1919.

This study is to determine how bilingualism could influence the list of Persian basic color terms and their order.

Another assumption is that, the old usual methods for obta...

Hierarchical macro-mesoporous silica materials co-incorporated with Cr and Ti 12 (MM-Si-Cr-Ti) were directly synthesized by adopting close-packed array of polystyrene 13 microsphere as hard template for macropore through a simple soaking-calcination way, where 14 the Si/Ti ratio was fixed at 200 and Si/Cr ratio varied from 200-10. Ti specie is highly dispersed 15 in the porous matrix and Cr spe...

Numerous networks as, for example, road networks, electrical networks and communication networks can be modeled by a graph. Many attempts have been made to determine how well such a network is "connected" or stated differently how much effort is required to break down communication in the system between at least some nodes. Two well-known measures that indicate how "reliable" a graph is are the...
