AIIA-iCAINE was established on 29 October 2021 under the mandate of the Ministry of Ayush at the All India Institute of Ayurveda in New Delhi, and it supports Ayurveda-based products, services and enterprises through mentorship, capacity building, institutional partnerships and industry engagement.

The challenge asks participants to use AyurParam to build artificial intelligence solutions that are trustworthy, transparent, safe and practical, and to apply them to Ayurvedic clinical practice, retrieval from classical texts, research, treatment planning and public health awareness.

The challenge is organised by Techfest of IIT Bombay in collaboration with the Ministry of Ayush and the All India Institute of Ayurveda, and it was launched at the sixth Foundation Day of the institute's incubation centre AIIA-iCAINE.

It is caused by the bacterium Vibrio cholerae, which spreads through food and water polluted with human faeces. The bacterium was identified by Robert Koch in 1883.

Amuktamalyada is a Telugu work, not a Sanskrit one, so this statement is wrong. Krishnadevaraya (ruled 1509–1529) was the greatest king of the Tuluva dynasty of Vijayanagara.

The resistance of a conductor depends on its material and shape, not on how much current flows through it. For a cylindrical conductor, R = ρL/A, where ρ is the resistivity of the material, L the length and A the area of cross-section.

Oxygen makes up about 21 per cent of dry air by volume, second only to nitrogen. Dry air near the ground is about 78 per cent nitrogen, 21 per cent oxygen and 0.93 per cent argon, which is the third most abundant gas.

The enzyme breaks the β-lactam ring that gives penicillin its power. Penicillin was discovered by Alexander Fleming in 1928 from the mould Penicillium notatum.

An ECG records the electrical signals that make the heart muscle contract with each beat. Each heartbeat starts at the sino-atrial (SA) node, the natural pacemaker in the right atrium.

An echo is sound that bounces back from a hard surface such as a wall, cliff or hill and reaches our ears again.

Both stress and pressure are force per unit area, so both are measured in newton per square metre, or pascal (Pa).

A step-up transformer raises an alternating voltage, using more turns in its secondary coil than in its primary. A transformer works on electromagnetic induction and only with alternating current.

She won Miss Universe in 1994, becoming the first Indian to do so, but she never held the Miss World title.

For an object between F and P, the image forms behind the mirror, not at infinity. When an object is placed between the pole and the principal focus of a concave mirror, the reflected rays spread out and never meet in front of the mirror.

It comes from the rise and fall of sea tides, a renewable source that is not among the traditional fuels.
