Notes:
Diesel is not cheaper then gasoline or petrol in all European and North American countries. In fact, it is generally more expensive compared to gasoline. Diesel is cheaper in India because it’s believed to be generally used by farmers and truck and bus fleets (local and intercity buses owned by state governments) and is subsidized. When burnt, Diesel offers a net heating value of 43.1 MJ/kg as opposed to 43.2 MJ/kg for gasoline. However, due to the higher density, diesel offers a higher volumetric energy density at 35.86 MJ/L (128 700 BTU/US gal) vs. 32.18 MJ/L (115 500 BTU/US gal) for gasoline, some 11% higher, which should be considered when comparing the fuel efficiency by volume. The CO2 emissions from diesel are 73.25 g/MJ, just slightly lower than for gasoline at 73.38 g/MJ.

Notes:
One common way to generate X-rays is to bombard a metal target by high energy electrons. X-rays covers wavelengths from about 10^–8 m (10 nm) down to 10^–13 m (10^–4 nm).

Notes:
The Chittor Fort or Chittorgarh is one of the largest forts in India. It is a UNESCO World Heritage Site. The fort was the capital of Mewar and is located in the present-day town of Chittor in Rajasthan.
