Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.

Sir Chandrasekhara Venkata Raman, discovered on 28 February 1928, that when a beam of coloured light entered a liquid, a fraction of the light scattered was of a different color, dependent on material property. This radiation effect of molecular scattering of light bears the name of ‘Raman Effect’, from which many applications in photonic communications and spectroscopy evolved. The Raman Effect is the process of scattering light particles by molecules of a medium.

Geostationary satellites are located exactly above the Earth’s equator and revolves around the Earth in a circular orbit. Their revolving speed and direction (West to East) are exactly same as that of the Earth, which makes it look stationary from the Earth’s surface.

EDUSAT or GSAT-3 is a communications satellite which was launched on 20th September, 2004 by the Indian Space Research Organisation. EDUSAT is the first Indian satellite built exclusively to serve the educational sector. It has revolutionised classroom teaching through IP based technology

Process Control Block (PCB, also called Task Controlling Block, Task Structure or Switchframe) is a data structure in the Operating System kernel containing the information needed to manage a particular process.The PCB is the manifestation of a process in an Operating System.

The National Chemical Laboratory (NCL) is an ~ Indian Government laboratory based in Pune, popularly known as NCL, a constituent member of the Council of Scientific and Industrial Research (CSIR) India, it was established in 1950

A geostationary orbit, geostationary Earth orbit or Geosynchronous Equatorial Orbit (GEO), is a circular orbit 35786 km (22236 mile) above the Earth’s equator and following the direction of the Earth’s rotation. An object in such an orbit has an orbital period equal to the Earth’s rotational period (one sidereal day).

The Richter magnitude scale (often shortened to Richter scale) was developed to assign a single number to quantify the energy that is released during an earthquake. An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth’s crust that creates seismic waves.
