Pichwai is not a Madhubani style at all; it is the painted cloth hung behind the image of Shrinathji at Nathdwara in Rajasthan, showing the seasons and the festivals of the deity.

Raghurajpur, with the neighbouring Dandasahi, is the village of the Chitrakar families who paint Pattachitra, engrave palm leaf and make the painted masks and the Jagannath vesha panels; almost every house in it is a workshop.

A cooling tower releases the heat of used cooling water to the atmosphere by evaporation or by air flow, so that the water leaving the plant is close to the temperature of the receiving river or lake.

Thermal and nuclear power stations draw large volumes of water to condense steam and return it several degrees warmer, which makes them the single largest source of waste heat in rivers, lakes and coastal waters.

The solubility of a gas in water decreases as the temperature of the water rises, so hot water discharged from a power station holds less dissolved oxygen.
