Sharjah, the city of United Arab Emirates (UAE), has been designated as the UNESCO World Book Capital 2019 by Irina Bokova, the Director-General of UNESCO, at the Headquarters of the International Federation of Library Associations (IFLA) at La Haye. The honour is in recognition of the Emirate’s pioneering role in supporting and expanding the local and regional publishing industries, promoting reading to become an intrinsic cultural practice, as well as embracing inter-cultural, knowledge-based dialogue. Sharjah was the first emirate in UAE to establish a formal school and a library. It was also the first emirate to house many cultural institutions like the Emirates Publishers Association and the Emirates’ writers Union. Sharjah is the 19th city to become World Book Capital. It is preceded by Conakry in 2017 and Athens in 2018.

RADAR - RAdio Detection And Ranging.

A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. 

Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.

Radio waves from the transmitter reflect off the object and return to the receiver, giving information about the object's location and speed.

Mihirakula, also Mahiragula, was one of the most important rulers of the Alchon Huns, who led a conquest and gained temporary control of Gandhara, Kashmir, northern and central India. Mihirakula was a son of Toramana, both of Huna heritage, and ruled the Indian part of the Hephthalite Empire.

Evaporation is the process that allows water to enter into the atmosphere.

Sunlight turns liquid water into water vapor which then rises higher into the atmosphere and forms into clouds.

Plants, too, help water get into the atmosphere through a process called transpiration.

The water cycle is a term for the movement of water between the Earth's surface, the sky and underground. Water evaporates due to heat from the sun. Hence, the water cycle is driven primarily by the energy from the sun.

This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.
