Sustainable Aviation Fuel (SAF)

India and Brazil decided to collaborate on production and use of Sustainable Aviation Fuels (SAF).

About SAF

  • Currently, SAF remains major mature and viable pathway to decarbonise aviation sector.
  • It is a liquid fuel currently used in commercial aviation which reduces CO2 emissions by up to 80%.
    • It contains fewer impurities (such as sulphur), which enables an even greater reduction in sulphur dioxide and particulate matter emissions.
  • It can be produced from a number of sources (feedstock) including waste oil and fats, green and municipal waste and non-food crops.
  • It can also be produced synthetically via a process that captures carbon directly from the air.

Criticality

Third indigenous Pressurized Heavy Water Reactor (PHWR) unit of the Rajasthan Atomic Power Project (RAPP) has attained criticality.

  • It is located at Rawatbhata. 
  • Earlier 2 PHWRs units of the Kakrapar Atomic Power Station in Gujarat have attained criticality. 

What is Criticality?

  • A reactor achieves criticality (and is said to be critical) when each fission event releases a sufficient number of neutrons to sustain an ongoing series of reactions.
  • The reactor is neither increasing nor decreasing in power—this is the ideal operating condition for energy production.

Credit Default Swaps (CDS)

Securities and Exchange Board of India (SEBI) allowed mutual funds to buy and sell Credit Default Swaps (CDS) to improve liquidity in corporate bond market.

  • A CDS is a financial derivative that allows an investor to swap or offset their credit risk with that of another investor.

Facial Recognition Technology (FRT)

Government has introduced the FRT two factor authentication process for delivering Take Home Ration (THR) as a pilot project.

  • THR is part of Integrated Child development scheme (ICDS). 
  • Two factor authentication: beneficiary’s photo will be captured and verified and a onetime password will be sent on their phones.

About FRT

  • An Artificial intelligence (AI) system which allows identification or verification of a person based on certain images or video data using complex algorithms.
  • Uses key features of the face and their respective distances from one another to morph a virtual facial map.
  • FRT can be used for two purposes:
    • 1:1 verification: matches a person’s facial map to a specific photograph 
    • 1:n identification: compares a person’s face against an entire database
