Brajkishore Prasad:- Gandhi was so impressed by Prasad's dedication that he set aside a full chapter on him in his autobiographical book, The Story of My Experiments with Truth, called "The Gentle Bihari".
The National Book Trust, India, recently published a biography titled Braja Kishore Prasad: The Hero of Many Battles, authored by Sachidanand Sinha.

The beads in various stages of manufacture from several sites such as Harappa, Chanhudaro and Dholavira reveal the stages involved in the production of these beads.
The Father of the Nation, Mahatma Gandhi had established Bihar Vidyapeeth in Bihar on February 6, 1921 with the donations of the general public. Its principals were appointed Deshratna Dr. Rajendra Prasad, Vice-Chancellor Brijkishore Prasad and Maulana Mazharul Haque. Recently, the 101st Foundation Day of Bihar Vidyapeeth was celebrated.

Visual: Ultrasonic cleaning.
Ultrasonic cleaning is a process that uses ultrasound (usually from 20–40 kHz) to agitate a fluid. The ultrasound can be used with just water, but use of a solvent appropriate for the object to be cleaned and the type of soiling present enhances the effect.
Ultrasonic activity (cavitation) helps the solution to do its job; plain water would not normally be effective. The cleaning solution contains ingredients designed to make ultrasonic cleaning more effective. For example, reduction of surface tension increases cavitation levels, so the solution contains a good wetting agent (surfactant).
Ultrasonic cleaning include small electronic parts, cables, rods, wires and detailed items, as well as objects made of glass, plastic, aluminium or ceramic.
Ultrasonic cleaning does not sterilize the objects being cleaned, because spores and viruses will remain on the objects after cleaning. In medical applications, sterilization normally follows ultrasonic cleaning as a separate step.

🔴 STEEL SLAG
▪️In News: Surat has become the first city in the country to get a processed steel slag (industrial waste) six-lane road.
▪️Steel Slag is an industrial by-product obtained from the steel manufacturing industry.
▪️It is generated from a steel furnace burning at around 1,500-1,600 degree centigrade in the form of molten flux material as an impurity.
▪️The thickness of the road is also 30% lesser than normal ones, while the durability is much longer due to the utilisation of steel slag.
▪️Other uses - It is used to treat acidic water. In Agricultural sector, due to its ability to correct soil acidity, it is used as silicate fertilizer that is capable of providing silicon to the plants.
▪️Steel Slag Road is a brainchild of the Central Road Research Institute (CRRI), NITI Aayog, and the Council of Scientific and Industrial Research (CSIR).
