Meanwhile, he had written to Abu Ya'far, the prefect of the dynamic city of Isfahan, offering his services. The new emir of Hamadan, hearing of this correspondence and discovering where Ibn Sina was hiding, incarcerated him in a fortress. War meanwhile continued between the rulers of Isfahan and Hamadan; in 1024 the former captured Hamadan and its towns, expelling the Tajik mercenaries. When the storm had passed, Ibn Sina returned with the emir to Hamadan, and carried on his literary labors. Later, however, accompanied by his brother, a favorite pupil, and two slaves, Ibn Sina escaped from the city in the dress of a Sufi ascetic. After a perilous journey, they reached Isfahan, receiving an honorable welcome from the prince.
What two cities were at war during this time?

As a landlocked country Tajikistan has no ports and the majority of transportation is via roads, air, and rail. In recent years Tajikistan has pursued agreements with Iran and Pakistan to gain port access in those countries via Afghanistan. In 2009, an agreement was made between Tajikistan, Pakistan, and Afghanistan to improve and build a 1,300 km (810 mi) highway and rail system connecting the three countries to Pakistan's ports. The proposed route would go through the Gorno-Badakhshan Autonomous Province in the eastern part of the country. And in 2012, the presidents of Tajikistan, Afghanistan, and Iran signed an agreement to construct roads and railways as well as oil, gas, and water pipelines to connect the three countries.
What year was the agreement signed?

In December 2009, then Indian Navy chief Admiral Nirmal Kumar Verma said at his maiden navy week press conference that concepts currently being examined by the Directorate of Naval Design for the second indigenous aircraft carrier (IAC-2), are for a conventionally powered carrier displacing over 50,000 tons and equipped with steam catapults (rather than the ski-jump on the Gorshkov/Vikramaditya and the IAC) to launch fourth-generation aircraft. Later on in August 2013 Vice Admiral RK Dhowan, while talking about the detailed study underway on the IAC-II project, said that nuclear propulsion was also being considered. The navy also evaluated the Electromagnetic Aircraft Launch System (EMALS), which is being used by the US Navy in their latest Gerald R. Ford-class aircraft carriers. General Atomics, the developer of the EMALS, was cleared by the US government to give a technical demonstration to Indian Navy officers, who were impressed by the new capabilities of the system. The EMALS enables launching varied aircraft including unmanned combat air vehicles (UCAV). The aim is to have a total of three aircraft carriers in service, with two fully operational carriers and the third in refit.
