The Tharu are the most widely distributed Scheduled Tribe of Uttar Pradesh, living along the Terai belt that runs below the Himalaya through Lakhimpur Kheri, Bahraich, Balrampur, Shrawasti, Siddharthnagar, Maharajganj and the neighbouring districts, so they appear in more districts of the state than any other notified tribe.

A good fuel should have a moderate ignition temperature, not a very low one.

Destructive distillation means heating coal strongly in the absence of air, so that it decomposes instead of burning. The solid left behind is coke, which is almost pure carbon and is used as a reducing agent in the extraction of iron and other metals and as a smokeless fuel.

When the oxygen supply is short, the carbon of the fuel is only partly oxidised and carbon monoxide is formed instead of carbon dioxide.

It is the lowest temperature to which a combustible substance must be heated before it begins to burn, and it is a fixed property of that substance; substances with a very low ignition temperature, such as petrol, alcohol and liquefied petroleum gas, are called inflammable substances and are stored with…

Carbon dioxide is about one and a half times as dense as air, so when released it forms a blanket over the burning material and separates it from atmospheric oxygen, removing one side of the fire triangle.

Petrol and kerosene are lighter than water and do not mix with it, so water poured on an oil fire sinks below the burning layer and carries it outwards, enlarging the fire instead of putting it out.

Coal forms by the slow burial and compression of plant matter, and the longer and deeper the process goes the more carbon is left behind as moisture and volatile matter are driven off.

Liquefied petroleum gas is obtained during the refining of petroleum and from natural gas processing, and it is chiefly a mixture of butane and propane, which liquefy under moderate pressure at ordinary temperature and so can be stored in a cylinder.

Its calorific value is about 150 kilojoules per gram, the highest of any known fuel, roughly three times that of petrol, and its only combustion product is water vapour, which makes it a clean fuel as well.

In this zone the supply of air is unrestricted, so combustion is complete and all the carbon of the fuel is converted to carbon dioxide, releasing the maximum heat.

Calorific value is the heat released on completely burning one gram of a substance, and among the four foods listed ghee has the highest, because it is almost entirely fat.

In spontaneous combustion a substance catches fire by itself, without any external flame being brought near it.

Goal 17 is the means-of-implementation goal: it covers finance, technology transfer, capacity building, trade, policy coherence, multi-stakeholder partnerships and the data and monitoring needed to track the other sixteen goals, and it is the reason the agenda is described as a global partnership rather than a list of national duties.

It was the first global conference to treat the environment as a subject of international policy, and the United Nations Environment Programme was created later that year as a direct result, with its headquarters at Nairobi in Kenya; the opening day of the conference, 5 June, is observed every year…

Goal 6 seeks to ensure the availability and sustainable management of water and sanitation for all, which includes safe and affordable drinking water, an end to open defecation, better water quality and the protection of water-related ecosystems; in India the Swachh Bharat Mission and the Jal Jeevan Mission are the…

The Millennium Development Goals were agreed after the United Nations Millennium Summit of 2000 and ran until 2015, covering extreme poverty and hunger, universal primary education, gender equality, child mortality, maternal health, HIV and other diseases, environmental sustainability and a global partnership for development.

It has been given the task of coordinating and overseeing the goals in India, mapping each goal and target to central ministries and to centrally sponsored schemes, and it publishes the SDG India Index, which scores states and Union Territories on their performance.

Formally the United Nations Conference on Environment and Development, it adopted Agenda 21, a non-binding action plan for the twenty-first century covering every level from the global to the local, along with the Rio Declaration, a statement of forest principles, the Framework Convention on Climate Change and the Convention on…

Goal 13 calls for urgent action to combat climate change and its impacts, and it expressly recognises the United Nations Framework Convention on Climate Change as the primary international forum for negotiating the global response.
