CSIR AMPRI CENTRE SCRIPT:

  • CSIR-AMPRI has been successfully adopting ‘Waste to Wealth’ strategy as the institute has developed radiation shielding materials utilizing industrial wastes as raw materials.
  • Significantly , a novel process for making lead free and highly effective shielding materials useful for the construction of X-ray diagnostic and CT scanner room has been developed utilizing industrial waste namely red mud and fly ash.
  • Foundation stone of CSIR-AMPRI Bamboo Composite Structure was laid.
  • Institute is working in the cutting-edge areas of advanced technologies . It is in the forefront during the pandemic time by undertaking research in collaboration with AIIMS, Bhopal in the area of development  of rapid electrochemical based diagnostic for detection of SARS-COV infection.
  • Various geopolymeric materials were also developed by CSIR-AMPRI utilizing Coal based Thermal Power Plant waste i.e. Fly-Ash and three US patents have been granted on geopolymeric materials.
  • A unique Centre for Advanced Radiation Shielding and Geopolymeric Materials with a total area of 455.52 Sq.m and Carpet Area of 906.24 Sq.m is being established.
  • The advances in geopolymeric materials will accelerate strategic applications such as development  of Thermal Resistant Geopolymeric Concrete for Missile /Rocket Launching Pad and development of Geopolymeric Bullet Proof Concrete for Bunkers; development of Graphene-Induced Geopolymeric Concrete and Geopolymeric Radiation Shielding Concrete.
  • In addition, it will also have advanced conventional applications such as development and upscaling of ready mix Geopolymeric Concrete for road applications and structural applications; development of Roller-Compacted Geopolymeric Concrete and development of pre-stressed Geopolymeric Concrete components.
  • The Centre  will enhance the knowledge for understanding the mechanism of Radiation Shielding and improvement in engineering properties of developed materials.
  • It will facilitate the upscaling of technologies in this area and provide technological support to Indian industry.
  • Another major facility inaugurated at CSIR-AMPRI was the Analytical High-Resolution Transmission Electron Microscope Laboratory. This laboratory houses Scanning Transmission Electron Microscope (STEM) with High-Angle Annular Dark Field Detector (HAADF) and Energy Dispersive Spectrometer (EDS) along with TEM sample preparation equipment such as, Ion milling system, Ultrasonic disc cutter, Dimple grinder, Disk punch, lapping disk and Diamond saw.
  • This system is capable of performing microanalysis such as micro diffraction, rocking beam channelling patterns, qualitative and quantitative X-ray spectroscopy analysis, particle size analysis, dislocation density and movement, precipitation, nucleation and growth.
  • CSIR-AMPRI has developed a knowhow of manufacturing environmentally friendly multifunctional bamboo composite material for modern housing and structures using abundantly available bamboo as a raw material.
  • The newly developed bamboo composite material can serve as a competitive, sustainable and environment friendly alternative material, useful in the construction of smart green buildings as it has very attractive features like, aesthetic appearance, acoustic & thermal insulation.
  • India is the second largest cultivator of bamboo, it has only 4% share of world trade and the bamboo wood technology has potential of increasing this trade share.

World Sparrow Day 2021:

  • Every year March 20 is observed as World Sparrow Day to raise awareness about the bird.
  • The need for marking this day was felt due to the tremendous decrease in its population. The house sparrow is on the verge of extinction.
  • The initiative was started by Nature Forever Society (NFS) of India, founded by Mohammed Dilawar, an Indian conservationist.
    • He started his work helping the house sparrow in Nashik.
    • He was also named one of the Heroes of the Environment for 2008 by Time magazine for his efforts.
  • The first World Sparrow Day was celebrated in 2010 in different parts of the world.
  • The main purpose or aim behind celebrating the day is to inform about the significance and importance of conservation and protection of the sparrows and other such birds. People also celebrate the day to admire and protect the beauty of biodiversity and nature.
  • Various kinds of campaigns, events, activities are organized on this day to encourage people to participate and contribute to the cause by bringing individuals and organisations around the world together.
  • The theme for the World Sparrow Day is ‘I Love Sparrows’ and is inspired with the hope that more people will celebrate the relationship between people and sparrows by making them remember the bond they share as people have lived in harmony with these little birds for 10,000 years.
  • Through this year’s theme, the main aim is to highlight how citizens from different walks of life are making amazing differences and expressing their love for sparrows by telling the world how they are helping conserve the little creature.
  • People are advised to make nests, put water for sparrows during the summer season or can also put bird feeders in gardens or any open area to protect the adorable bird.

National Vaccination Day 2021:

  • National Vaccination Day is celebrated every year in the country on March 16 as on the same day the first dose of Oral Polio Vaccine was given in India in 1995. The day is observed to celebrate the Indian government’s Pulse Polio Campaign which was an initiative to eradicate polio from the country.
  • As per the program, 2 oral drops of polio vaccine were provided for children from the age of 0 to 5 years. This program became a success gradually, as in 2014 India became a polio free country.
  • Over a last few decades, vaccines in the country have become an important weapon to fight some fatal diseases like TB, tetanus and more and have saved so many lives.
  • Therefore, this day states that the main importance of vaccination in today’s world cannot be overlooked. There are plenty of vaccination campaigns running across the world to defeat deadly health conditions such as smallpox, measles and especially COVID-19.
