About Liberalised Remittances Scheme (LRS)

• LRS allows Indian residents to freely remit up to USD $250,000 per financial year for current or capital account transactions or a combination of both. Any remittance exceeding this limit requires prior permission from the RBI.
• The scheme was introduced by RBI on February 4, 2004.
• Who can remit funds under LRS?
  • Only individual Indian residents, including minors, are permitted to remit funds under LRS.
  • Corporates, partnership firms, HUF, trusts, etc., are excluded from its ambit.
• Frequency of Remittances:
  • There are no restrictions on the frequency of remittances under LRS. 
  • Once a remittance is made for an amount up to USD 2,50,000 during the financial year, a resident individual would not be eligible to make any further remittances under this scheme.
•  Types of transactions permitted:
  • Opening of foreign currency account abroad with a bank;
  •  Acquisition of immovable property abroad, overseas direct investment (ODI), and overseas portfolio investment (OPI);

About Pelagic Birds:

• These are seabirds that live on open seas and oceans rather than inland or around more restricted waters such as lakes and rivers.
• They can be found thousands of miles offshore but can get blown onto land during high winds and storms.  
• The only other time they come inland is to breed.
• The most familiar types of pelagic birds include albatrosses, frigatebirds, fulmars, petrels, shearwaters, and tropicbirds.

Features:

• They feed on planktonic crustaceans, squid and hunt fish far from the land.
• Generally, they have dense, waterproof feathers and layers of fat to keep them warm. 
• They have exceptionally long and thin wings that allow them to fly effortlessly for long periods without rest.
• Many pelagic birds have special salt glands. This allows them to drink seawater and discard extra salt accidentally ingested with their oceanic prey.
• Some have webbed or partially webbed feet for swimming, plucking fish from the shallows, or executing precise, plunging dives. 
• In general, seabirds live longer than other wild birds; most have an average lifespan of 50 years.
• Almost all seabirds live in colonies, migrate annually, and mate for life.

Q) What is meant by Pelagic?

Anything pelagic has something to do with the ocean, especially the open area far from the shore. Pelagic birds and fish — like tuna, jellyfish, and the Atlantic puffin — live in the open ocean.

About Skin Bank

• A skin bank is a place where cadaveric skin is processed and preserved under optimal conditions from where it can be used for the benefit of Burn victims.
• Skin can be donated after Death within 6 hours from the time of Death.
• Anyone can Donate Skin irrespective of sex & blood group, the minimum age of the donor should be 18 years.
• There is no upper age limit, even a 100-year-old person can donate his skin and it will be used for treatment.
• The skin of persons suffering from AIDS, Hepatitis B & C, Sexually Transmitted Diseases, Skin Cancer, Active skin Disease and Septicemia are considered unfit for donation.
• At the time of skin harvesting, a blood sample from the body of the deceased is also taken and a necessary test for HIV, Viral markers & Hepatitis is carried out at the Skin Bank.
• An old history of trauma or old history of burns does not make the donor unfit for skin donation.
• Skin is generally preserved in 85% glycerol solution. It is stored between 4-5 degree Celsius and it can be stored for a period of up to 5 years.
• The country has 16 skin banks — a facility where the skin of deceased persons can be donated — with seven in Maharashtra, four in Chennai, three in Karnataka, and one each in Madhya Pradesh and Odisha.

About the South African Customs Union (SACU)

• It is the world’s oldest customs union which was established in 1910.
• Member countries: South Africa, Namibia, Botswana, Lesotho, and Eswatini (formerly Swaziland).
• Headquarter: Windhoek (Namibia)
• It was administered by South Africa, through the 1910 and 1969 Agreements.
• The customs union collected duties on local production and customs duties on members’ imports from outside SACU, and the resulting revenue was allocated to member countries in quarterly instalments utilizing a revenue-sharing formula.
• Negotiations to reform the 1969 Agreement started in 1994, and a new agreement was signed in 2002. The new arrangement was ratified by SACU Heads of State.
• The Economic structure of the Union links the Member states by a single tariff and no customs duties between them.
• The Member States form a single customs territory in which tariffs and other barriers are eliminated on substantially all the trade between the Member States for products originating in these countries; and there is a common external tariff that applies to nonmembers of SACU.

Why in the news?

• According to the Department of Science and Technology, scientists now are one step closer to identifying the source of the Solar Mean Magnetic Field (SMMF).

About Solar Mean Magnetic Field:

• It is the mean value of the line-of-sight (LOS) component of the solar vector magnetic field averaged over the visible hemisphere as well as its relationship with Interplanetary Magnetic Field (IMF).
• The sun contains the corona (the outer shell of the sun’s atmosphere), the photosphere (the visible surface), and the chromosphere (near-transparent layer, just above the photosphere) with the magnetic field generated by electrical currents acting as a magnetic dynamo inside the sun.
• However, so far, the studies on the SMMF have mostly been confined to the magnetic field measurements at the photosphere.
• New Findings:
  • Scientists in their quest to understand if and how the SMMF at chromospheric heights is related to the SMMF at photospheric heights have found a very good similarity between the two.
  • The value of chromospheric SMMF is lower than the photospheric SMMF, thereby suggesting that the primordial magnetic field inside the sun could be a source of the SMMF.
  • They calculated and analysed the SMMF using magnetic field measurements at the chromosphere, in conjunction with that of photospheric measurements.
  • These electrical currents are generated by the flow of hot, ionised gases in the sun’s convection zone.

Q) What is Solar flare?
A solar flare is a sudden and intense eruption of energy from the Sun's surface. It is a result of the release of a large amount of magnetic energy in a relatively short period of time. Solar flares are most commonly observed in the vicinity of sunspots, which are regions of intense magnetic activity on the Sun's surface.
