The role of the gas is to prevent evaporation of the filament, without introducing significant heat losses. For these properties, chemical inertness and high atomic or molecular weight is desirable. The presence of gas molecules knocks the liberated tungsten atoms back to the filament, reducing its evaporation and allowing it to be operated at higher temperature without reducing its life (or, for operating at the same temperature, prolongs the filament life). It however introduces heat losses (and therefore efficiency loss) from the filament, by heat conduction and heat convection.

What is the purpose of the gas in a light bulb?
Answer: to prevent evaporation of the filament, without introducing significant heat losses

On 10 October 2009, Armenia and Turkey signed protocols on normalisation of relationships, which set a timetable for restoring diplomatic ties and reopening their joint border. The ratification of those had to be made in the national parliaments. In Armenia it passed through the required by legislation approval of the Constitutional Court and was sent to the parliament for the final ratification. The President had made multiple public announcements, both in Armenia and abroad, that as the leader of the political majority of Armenia he assured the ratification of the protocols if Turkey also ratified them. Despite this, the process stopped, as Turkey continuously added more preconditions to its ratification and also "delayed it beyond any reasonable time-period".

When did Armenia and Turkey initiate an attempt to reopen their border?
Answer: 10 October 2009

The religious art of Nepal and Kathmandu in particular consists of an iconic symbolism of the Mother Goddesses such as: Bhavani, Durga, Gaja-Lakshmi, Hariti-Sitala, Mahsishamardini, Saptamatrika (seven mother goddesses), and Sri-Lakshmi(wealth-goddess). From the 3rd century BC, apart from the Hindu gods and goddesses, Buddhist monuments from the Ashokan period (it is said that Ashoka visited Nepal in 250 BC) have embellished Nepal in general and the valley in particular. These art and architectural edifices encompass three major periods of evolution: the Licchavi or classical period (500 to 900 AD), the post-classical period (1000 to 1400 AD), with strong influence of the Palla art form; the Malla period (1400 onwards) that exhibited explicitly tantric influences coupled with the art of Tibetan Demonology.

What is Sri-Lakshmi a deity of?
Answer:
wealth
