Standing at the head of a grand colonnade leading to Palmyra’s temple to the Mesopotamian god Bel, the arch had been built between 193 and 211 AD, in honour of the Roman emperor Septimius Severus, who had visited the city which at the time had been one of Rome’s wealthiest colonies.

The arch’s destruction was described by Mr Abdulkarim as “a crime in every sense of the word.”

The creation of the 5.5m (18ft) high scale model began when Roger Michel, the IDA’s executive director realised the Institute’s Million Images Database of 3D photographs taken by volunteersthe UE concurrently. These carriers aggregated together are referred to as Component Carriers (CCs). Each cell can be a component carrier, and cells (component carriers) served by different eNBs cannot be aggregated. The bandwidth of each carrier cannot go beyond 20 MHz for back compatibility with an LTE UE.
One of the component carriers aggregated for the UE is defined as a Primary Component Carrier (PCC), and the other component carriers are referred to as Secondary Component Carriers (SCCs).
Carrier aggregation of a Frequency Division Duplex (FDD) carrier and a Time Division Duplex (TDD) carrier may be supported in an evolved system subsequent to the LTE-A system. Since the FDD carrier operates in a different operating mode from the TDD carrier, a new uplink Acknowledge/Negative Acknowledge (ACK/NACK) transmission solution may
