It lies on the western margins of continents between about 30 and 45 degrees latitude, and the wind belts shift with the sun: in winter the rain bearing westerlies move towards the equator and reach it, while in summer the dry descending air of the subtropical high sits over it.

In Koppen scheme the capital A stands for the tropical group, in which the coldest month is still above 18 degrees Celsius, and the small f stands for rain in every month of the year, so Af is the equatorial or tropical rainforest climate of the Amazon, the Congo and…

Bugyal is the local name in Uttarakhand for the alpine meadows that lie above the tree line in the Greater Himalayas, used by shepherds for summer grazing; in Kashmir the same meadows are called marg, which gives the names Gulmarg and Sonmarg.

North America and Prairie is right, as the prairies are the temperate grasslands of the United States and Canada and the granary of the world.

The Gobi lies in central Asia, across southern Mongolia and northern China, and it is a cold mid latitude desert: it is dry not because of the trade winds but because it is far from the sea and the Himalayan and other ranges cut off the monsoon, and its winters…

It is the polar belt beyond about 70 degrees latitude, where the warmest month stays below 10 degrees Celsius and the subsoil remains frozen as permafrost, so Koppen codes it ET in his polar E group.

The Pampas are the temperate grasslands of the lower Parana and Plata basin, spread mainly over Argentina and extending into Uruguay.

The second line at Koraput, set up with an investment of Rs 218 crore, exists to meet their rising requirement.

That is the investment behind the second Shakti engine production line being highlighted at the Koraput event, and the added capacity is intended for indigenous helicopter platforms, named in the announcement as the Dhruv Advanced Light Helicopter and the Prachand Light Combat Helicopter.

The two-thousandth engine from this plant is being handed over on 6 October 2026, with the Raksha Mantri inaugurating the event and the Chief Minister of Odisha among those attending.

At the Visakhapatnam ceremony the Raksha Mantri will launch the first ship of the class and, on the same day, lay the keel of the fifth and last ship, which marks the programme's move towards series production rather than one-off construction.

Each of the five Fleet Support Ships is a vessel of this size, built to replenish warships while they remain at sea by passing across fuel, stores and provisions, so that a task force can keep operating without returning to harbour.

When a solid is divided into nanoparticles its total surface area grows enormously while the mass stays the same, so a very large fraction of the atoms lies exposed on the surface with unsatisfied bonds; chemical reactions happen at surfaces, so reactivity and catalytic activity rise sharply, which is why…

Gerd Binnig and Heinrich Rohrer built it at the IBM laboratory in Zurich in 1981; a sharp metal tip is moved a fraction of a nanometre above a conducting surface and the quantum tunnelling current between tip and sample maps the atoms one by one, work that brought them the…

The Nobel Prize in Chemistry of 2023 went to Moungi Bawendi, Louis Brus and Alexei Ekimov for the discovery and synthesis of quantum dots, semiconductor nanocrystals whose emitted colour depends on their size because of quantum confinement, and which are used in television displays, in light emitting diodes and as…

In 1911 the Dutch physicist Heike Kamerlingh Onnes, who had already liquefied helium, cooled mercury to about four kelvin and found that its electrical resistance vanished completely, which is the discovery of superconductivity and won him the Nobel Prize in Physics in 1913.
