  • Choudhary Rehmat Ali: Man behind the name ‘Pakistan’

    pakistan

    In this article, we take you to the history of Pakistan (which is on the brink of its demise) and the facts behind its naming.

    Jinnah and Pakistan

    • Muhammad Ali Jinnah is remembered as the founder of Pakistan, its “Qaid e Azam”, or the “Great Leader.”
    • He led a movement that transformed a weak idea of a sovereign Islamic state in British India’s north western provinces into reality.
    • But he was not the first to come up with the idea of Pakistan, nor was he its original champion.

    Rehmat Ali: Coining the term ‘Pakistan’

    • Choudhary Rehmat Ali can be credited with coining the “term” Pakistan, styling himself as the “Founder of the Pakistan National Movement”.
    • On January 28, 1933, he released a pamphlet titled “Now or Never: Are we to live or perish forever”.
    • In it he made a vehement “appeal on behalf of the thirty million Muslims of PAKISTAN, who live in the five Northern Units of India… for the recognition of their national status.
    • He highlighted the distinctiveness with the other inhabitants of India citing religious, social and historical grounds.
    • According to many historians, this can be seen as the genesis of the very idea of Pakistan; an idea which would become mainstream by the 1940s.

    Ali’s appeal

    • Rehmat Ali’s appeal was as much a critique of Nationalism wave.
    • He distributed pro-Pakistan pamphlets in the Third Round Table Conference (1932).
    • Fearing that the Muslim minority will be subsumed by the Hindu population under the proposed constitution, he advocated for a separate, sovereign entity.
    • For him, British India was not the home of one single nation but rather the designation of a State created by the British for the first time in history.

    His idea of Pakistan

    • This nation that Rehmat Ali called his own was Pakistan, including “five Northern Provinces of India” – Punjab (P), North- West Frontier Province or the Afghan Province (A), Kashmir (K), Sindh(S) and Balochistan (tan).
    • He would call its Pakistan.
    • He argued that this region, with its “distinct marks of nationality,” would be “reduced to a minority of one in ten,” in a united Indian federation.

    Exposition of the “Two Nation Theory”

    • Rehmat Ali was not a politician. In 1947, Ali’s dream became a reality.
    • Nor did he stay in the subcontinent for much of the 1930s and 1940s when the struggle for Pakistan was taking shape.
    • His contribution to Pakistan are solely limited to his writings and ideas.
    • Unlike Iqbal, more popularly known as the philosopher behind Pakistan’s creation, Ali’s work remained restricted to a far smaller audience.
    • But it was important, arguably essential, for Pakistan’s creation.
    • In his work, we see the most radical exposition of the “Two Nation Theory”, later made famous by Jinnah and the Muslim League.

    How Jinnah overtook Rehmat Ali?

    • Things began to change from 1937 onwards, after Jinnah fell out with the Congress.
    • With the leader’s rhetoric turning increasingly separationist, Rahmat Ali’s articulation of Pakistan found its way into mainstream discourse.
    • In 1940, at the Muslim League’s Lahore session, the famous Lahore Resolution was passed.
    • It advocated that the geographical contiguous units in the Muslim-majority areas in India’s “North-Western and Eastern Zones of India, be grouped to constitute Independent States.
    • While this resolution did not mention “Pakistan,” Jinnah’s ideas echoed Rahmat Ali’s.
    • Somewhere between 1940 and 1943, the term “Pakistan” started being used by Jinnah and other Muslim League leaders in their speeches and correspondence.

  • Mughal Gardens will now be called as Amrit Udyan

    mughal

    The Rashtrapati Bhavan gardens — popularly known as the Mughal Gardens was renamed as Amrit Udyan.

    The Amrit Udyan

    • Edwin Lutyens had finalized the designs of the Mughal Gardens in 1917, but it was only during the year 1928-1929 that planting was done.
    • It is spread across 15 acres and it incorporates both Mughal and English landscaping styles.
    • The main garden has two channels intersecting at right angles dividing the garden into a grid of squares- a Charbagh (a four-cornered garden)- a typical characteristic of Mughal landscaping.
    • There are six lotus-shaped fountains at the crossings of these channels rising to a height of 12 feet.
    • The gardens house nearly 2500 varieties of Dahlias and 120 varieties of roses.

    Why was it earlier named as Mughal Gardens?

    • The garden is designed in Persian style of landscaping or what we call as ‘‘Mughal Gardens”.
    • In fact, Edward Lutyens who designed the Viceroy’s House, what we call today as Rashtrapati Bhavan had deliberately used Mughal architectural details as part of the British appeasement plan.
    • We see Chajja (dripstone), the Chattri (domed kiosk), the Jali (pierced screen) and many other Indian architectural features liberally used there.
    • Mughal canals, terraces and flowering shrubs are beautifully blended with European flowerbeds, lawns and private hedges.

    Back2Basics: Mughal Gardening in India- The Charbagh Style

    mughal

    • The Mughals were known to appreciate gardens. In Babur Nama, Babur says that his favourite kind of garden is the Persian charbagh style (literally, four quadrants garden).
    • The charbagh structure was intended to create a representation of an earthly utopia‘jannat’ – in which humans co-exist in perfect harmony with all elements of nature.
    • Defined by its rectilinear layouts, divided in four equal sections, these gardens can be found across lands previously ruled by the Mughals.
    • From the gardens surrounding Humanyun’s Tomb in Delhi to the Nishat Bagh in Srinagar, all are built in this style – giving them the moniker of Mughal Gardens.
    • A defining feature of these gardens is the use of waterways, often to demarcate the various quadrants of the garden.
    • Fountains were often built, symbolising the “cycle of life.”

  • Munroe Thuruthu: Kerala’s Sinking Island

    munroe

    A study conducted by the National Centre for Earth Science Studies (NCESS) has revealed anthropogenic interventions as the main reason for the sinking of Munroe Thuruthu Kerala’s, Kerala’s Sinking Island.

    Note: This Island has nothing to do with Thomas Monroe, the erstwhile Governor of Madras Presidency (1820-27).

    Munroe Thuruthu

    • Munroe Thuruthu is an inland island group located at the confluence of Ashtamudi Lake and the Kallada River, in Kollam district of Kerala.
    • The place is named in honour of Resident Colonel John Munro of the former Princely State of Travancore.
    • It is a group of eight small islets comprising a total area of about 13.4 km2.
    • This island is also known as “Sinking Island of Kerala”.

    How was this island inhabited?

    • In 1795 the British established their supremacy in South India and the princely state of Travancore came under their governance.
    • From 1800 onwards, a Resident was appointed by East India Company as administrative head of Travancore.
    • The first Resident was Colonel Colin Macaulay, followed by Colonel John Munro.
    • During his tenure Munro oversaw the land reclamation efforts in the delta where Kallada River joins Ashtamudi Lake and the reclaimed island was named after him as Munroe Island.

    Why in news?

    • The islanders are facing steady land subsidence, tidal flooding and lower agricultural productivity, all of which have triggered a mass exodus from the region.
    • According to the study, almost 39% of the land area of the Munroe Thuruthu has been lost with Peringalam and Cheriyakadavu islands recording a land depletion of around 12% and 47% respectively.
    • The study finds that anthropogenic activities have considerably affected the isostatic conditions and land neutrality of Munroe Thuruthu.

  • What is Immune Imprinting?

    A slew of recent studies has shown that a phenomenon in our bodies, called immune imprinting, might be making new boosters vaccines far less effective than expected for coronavirus infection.

    What is Immune Imprinting?

    • Immune imprinting is a tendency of the body to repeat its immune response based on the first variant it encountered.
    • Our body does this through infection or vaccination — when it comes across a newer or slightly different variant of the same pathogen.
    • The phenomenon was first observed in 1947, when scientists noted that “people who had previously had flu, and were then vaccinated against the current circulating strain, produced antibodies against the first strain.
    • At the time, it was termed the ‘original antigenic sin’ but today, it’s commonly known as imprinting.

    How imprinting works for immune system?

    • Imprinting acts as a database for the immune system, helping it put up a better response to repeat infections.
    • After our body is exposed to a virus for the first time, it produces memory B cells that circulate in the bloodstream and quickly produce antibodies whenever the same strain of the virus infects again.
    • The problem occurs when a similar, not identical, variant of the virus is encountered by the body.
    • In such cases, the immune system, rather than generating new B cells, activates memory B cells.
    • This in turn produce antibodies that bind to features found in both the old and new strains, known as cross-reactive antibodies.

    Are the booster doses completely useless?

    • These cross-reactive antibodies do offer some protection against the new strain,.
    • However they are not as effective as the ones produced by the B cells when the body first came across the original virus.

    How to circumvent immune imprinting?

    • Currently, several ongoing studies are trying to find a way to deal with imprinting.
    • Some scientists have said nasal vaccines might be better at preventing infections than injected ones.
    • They believe the mucous membranes would create stronger protection, despite carrying some imprint of past exposure.
    • Researchers are also trying to find if spacing out coronavirus vaccine shots on an annual basis, could help with the problem of imprinting.

  • Who was Goswami Tulsidas (1511–1623)?

    tulsidas

    Tulsidas has come into controversy due to some of its verses (Chaupai) mentioned in the Ramcharitmanas.

    Who was Tulsidas?

    • Tulsidas, a Brahmin whose original name was Ram Bola Dubey, is believed to have been born in Rajapur by the Yamuna in today’s Banda district.
    • He composed the Ramcharitmanas on the bank of the Ganga in Varanasi — he is said to have begun writing on Ram Navami day in 1574, and completed the poem over the next few years.
    • Tulsidas lived in the time of Emperor Akbar, and some believe that he was in touch with Abdurrahim Khan-e-Khanan, the son of Akbar’s commander Bairam Khan.

    The Ramcharitmanas

    • The poem was written in the 16th century in the Awadhi dialect that is mainly spoken in the areas that are today’s Lucknow, Prayagraj, and Ayodhya districts.
    • It was written in the Avdhi dialect. The sacred chant ‘Hanuman Chalisa’ is a part of it.
    • It is divided into seven chapters (Kand) that tell the story of Lord Ram from birth to his becoming King of Ayodhya.

    Why is Ramcharitmanas so famous?

    • The Ramcharitmanas is based on the Ramayana, sage Valmiki’s great epic.
    • It is the holiest book of the Indo-Gangetic region, and among the world’s most read holy books — by one estimate, Geeta Press (Gorakhpur) has sold almost 7 crore copies.
    • Across the Hindi heartland, a reference to “Ramayan” often actually means Ramcharitmanas.
    • Tulsidas made the story of Lord Ram popular among the masses because he wrote in the regional dialect that most people understood.

    Tulisdas and political controversies

    • While in the Ramcharitmanas, Lord Ram is maryada purushottam, the epitome of righteousness, his conduct has been criticised by leaders of anti-Brahmin movements like E V Ramasamy Periyar.
    • One of the 22 pledges that Dr B R Ambedkar administered to his followers while embracing Buddhism in October 1956 was: “I shall have no faith in Rama and Krishna, who are believed to be incarnation of God, nor shall I worship them.”
    • Non-upper caste assertion in politics has sometimes been manifested in criticism of the Ramcharitmanas.
    • Critics have used these parts of the poem to accuse Tulsidas of being against the non-upper castes and women, and a flagbearer of the idea of Brahminical superiority.

  • What is a Living Will?

    A five-judge Bench of the Supreme Court headed by Justice K M Joseph agreed to significantly ease the procedure for passive euthanasia in the country by altering the existing guidelines for ‘living wills’.

    What is Living Will?

    • A living will is a legal document detailing the type and level of medical care one wants to receive if they are unable to make decisions or communicate their wishes when care is needed.
    • A living will addresses many life-threatening treatments and procedures, such as resuscitation, ventilation, and dialysis.
    • A person can appoint a healthcare proxy to make decisions regarding care when they are unable to do so.
    • A living trust is a legal document that addresses how the assets of the incapacitated person should be managed.
    • People can enlist the services of an estate planner or an attorney to help draft or review a living will.

    Living Will in India

    • It was first laid down in its 2018 judgment in Common Cause vs. Union of India & Anr, which allowed passive euthanasia.
    • It was in response to the Aruna Shanbaug Case where protagonists were arguing in favor of mercy killing to Aruna.
    • The guidelines pertained to questions such as who would execute the living will, and the process by which approval could be granted by the medical board.
    • It declared that an adult human being having mental capacity to take an informed decision has right to refuse medical treatment including withdrawal from life-saving devices.

    What is Euthanasia?

    • Euthanasia refers to the practice of an individual deliberately ending their life, oftentimes to get relief from an incurable condition, or intolerable pain and suffering.
    • Euthanasia, which can be administered only by a physician, can be either ‘active’ or ‘passive’.
    • Active euthanasia involves an active intervention to end a person’s life with substances or external force, such as administering a lethal injection.
    • Passive euthanasia refers to withdrawing life support or treatment that is essential to keep a terminally ill person alive.

    What is the legal history of this matter?

    • Passive euthanasia was legalized in India by the Supreme Court in 2018, contingent upon the person having a ‘living will’.
    • It must be a written document that specifies what actions should be taken if the person is unable to make their own medical decisions in the future.
    • In case a person does not have a living will, members of their family can make a plea before the High Court to seek permission for passive euthanasia.

    What did the SC rule in 2018?

    • The Supreme Court allowed passive euthanasia while recognising the living wills of terminally-ill patients who could go into a permanent vegetative state.
    • It was required to be signed by an executor (the individual seeking euthanasia) in the presence of two attesting witnesses and to be further countersigned by a Judicial Magistrate of First Class (JMFC).
    • The court issued guidelines regulating this procedure until Parliament passed legislation on this.
    • However, this has not happened, and the absence of a law on this subject has rendered the 2018 judgment the last conclusive set of directions on euthanasia.

    What was the situation before 2018?

    • P Rathinam vs Union Of India, 1994: In a case challenging the constitutional validity of Section 309 of the IPC — which mandates up to one year in prison for attempt to suicide the Supreme Court deemed the section to be a “cruel and irrational provision”.
    • Gian Kaur vs The State Of Punjab, 1996: Two years later, a five-judge Bench of the court overturned the decision in P Rathinam, saying that the right to life under Article 21 did not include the right to die, and only legislation could permit euthanasia.
    • Aruna Ramchandra Shanbaug vs Union Of India & Ors, 2011: SC allowed passive euthanasia for Aruna Shanbaug, a nurse who had been sexually assaulted in Mumbai in 1973, and had been in a vegetative state since then. The court made a distinction between ‘active’ and ‘passive’, and allowed the latter in “certain situations”.

    Key observations by Law Commission

    • Earlier, in 2006, the Law Commission of India in its 196th Report’ had said that a doctor who obeys the instructions of a competent patient to withhold or withdraw medical treatment does not commit a breach of professional duty and the omission to treat will not be an offence.
    • It had also recognised the patient’s decision to not receive medical treatment, and said it did not constitute an attempt to commit suicide under Section 309 IPC.
    • Again, in 2008, the Law Commission’s ‘241st Report On Passive Euthanasia: A Relook’ proposed legislation on ‘passive euthanasia’, and also prepared a draft Bill.

    What was the old cumbersome process?

    • The treating physician was required to constitute a board comprising three expert medical practitioners from specific but varied fields of medicine, with at least 20 years of experience.
    • They would decide whether to carry out the living will or not.
    • If the medical board granted permission, the will had to be forwarded to the District Collector for his approval.
    • The Collector was to then form another medical board of three expert doctors, including the Chief District Medical Officer.
    • Only if this second board agreed with the hospital board’s findings would the decision be forwarded to the JMFC, who would then visit the patient and examine whether to accord approval.
    • This cumbersome process will now become easier.

    Recent changes after the SC’s order this week

    • Medical board: Instead of the hospital and Collector forming the two medical boards, both boards will now be formed by the hospital.
    • 5 year experienced doctor: The requirement of 20 years of experience for the doctors has been relaxed to five years.
    • Magistrate approval not required: The requirement for the Magistrate’s approval has been replaced by an intimation to the Magistrate.
    • No witness required: The 2018 guidelines required two witnesses and a signature by the Magistrate; now a notary or gazetted officer can sign the living will in the presence of two witnesses instead of the Magistrate’s countersign.
    • HC for appeal: In case the medical boards set up by the hospital refuses permission, it will now be open to the kin to approach the High Court which will form a fresh medical team.

    Different countries, different laws

    • NETHERLANDS, LUXEMBOURG, BELGIUM allow both euthanasia and assisted suicide for anyone who faces “unbearable suffering” that has no chance of improvement.
    • SWITZERLAND bans euthanasia but allows assisted dying in the presence of a doctor or physician.
    • CANADA had announced that euthanasia and assisted dying would be allowed for mentally ill patients by March 2023; however, the decision has been widely criticised, and the move may be delayed.
    • UNITED STATES has different laws in different states. Euthanasia is allowed in some states like Washington, Oregon, and Montana.
    • UNITED KINGDOM considers it illegal and equivalent to manslaughter.

    Justification for Euthanasia/Assisted Suicide

    • It provides a way to relieve extreme pain.
    • Euthanasia can save life of many other people by donation of vital organs.

    Conclusion

    • India officially recognizes that- “every single citizen is entitled to and reserves the right to die with dignity.”
    • Hon’ble Supreme Courts’ recent updated guidelines are a major move in this direction.

  • Earth’s inner core rotating slower than surface: Study

    earth

    Earth’s inner core, a hot iron ball the size of Pluto, has stopped spinning faster than the planet’s surface and might now be rotating slower than it, research suggested.

    A quick recap of Earth’s Interior

    earth

    Structure of earth’s interior is fundamentally divided into three layers – crust, mantle and core.

    [A] Crust

    • It is the outermost solid part of the earth, normally about 8-40 kms thick.
    • It is brittle in nature.
    • Nearly 1% of the earth’s volume and 0.5% of earth’s mass are made of the crust.
    • The thickness of the crust under the oceanic and continental areas are different. Oceanic crust is thinner (about 5kms) as compared to the continental crust (about 30kms).
    • Major constituent elements of crust are Silica (Si) and Aluminium (Al) and thus, it is often termed as SIAL(Sometimes SIAL is used to refer Lithosphere, which is the region comprising the crust and uppermost solid mantle, also).
    • The mean density of the materials in the crust is 3g/cm3.
    • The discontinuity between the hydrosphere and crustis termed as the Conrad Discontinuity.

     [B] Mantle

    • The portion of the interior beyond the crust is called as the mantle.
    • The discontinuity between the crust and mantleis called as the Mohorovich Discontinuity or Moho discontinuity.
    • The mantle is about 2900kms in thickness.
    • Nearly 84% of the earth’s volume and 67% of the earth’s mass is occupied by the mantle.
    • The major constituent elements of the mantle are Silicon and Magnesium and hence it is also termed as SIMA.
    • The density of the layer is higher than the crust and varies from 3.3 – 5.4g/cm3.
    • The uppermost solid part of the mantle and the entire crust constitute the Lithosphere.
    • The asthenosphere (in between 80-200km) is a highly viscous, mechanically weak and ductile, deforming region of the upper mantle which lies just below the lithosphere.
    • The asthenosphere is the main source of magma and it is the layer over which the lithospheric plates/ continental plates move (plate tectonics).
    • The discontinuity between the upper mantle and the lower mantleis known as Repetti Discontinuity.
    • The portion of the mantle which is just below the lithosphere and asthenosphere, but above the core is called as Mesosphere.

    [C] Core

    • It is the innermost layer surrounding the earth’s centre.
    • The core is separated from the mantle by Guttenberg’s Discontinuity.
    • It is composed mainly of iron (Fe) and nickel (Ni) and hence it is also called as NIFE.
    • It constitutes nearly 15% of earth’s volume and 32.5% of earth’s mass.
    • It is the densest layer of the earth with its density ranges between 9.5-14.5g/cm3.
    • It spins independently because it floats in the liquid metal outer core. One cycle of the swing is about seven decades approximately.
    • It consists of two sub-layers: the inner core and the outer core.
    • The inner core is in solid state and the outer core is in the liquid state (or semi-liquid).
    • The discontinuity between the upper core and the lower core is called as Lehmann Discontinuity.
    • Barysphere is sometimes used to refer the core of the earth or sometimes the whole interior.

    What should one understand about the interior of the earth?

    • It is not possible to know about the earth’s interior by direct observations because of the huge size and the changing nature of its interior composition.
    • It is an almost impossible distance for the humans to reach till the centre of the earth (The earth’s radius is 6,370 km).
    • The rapid increase in temperature below the earth’s surface is mainly responsible for setting a limit to direct observations inside the earth.

    Sources of Information about the interior of the earth

    Direct Sources:

    1. Rocks from mining area
    2. Volcanic eruptions

    Indirect Sources

    1. By analyzing the rate of change of temperature and pressurefrom the surface towards the interior.
    2. Meteors, as they belong to the same type of materials earth is made of.
    3. Gravitation, which is greater near poles and less at the equator.
    4. Gravity anomaly, which is the change in gravity value according to the mass of material, gives us information about the materials in the earth’s interior.
    5. Magnetic sources.
    6. Seismic Waves: the shadow zones of body waves (Primary and secondary waves) give us information about the state of materials in the interior.

    What is the new study about?

    • Exactly how the inner core rotates has been a matter of debate between scientists— and the latest research is expected to prove controversial.
    • A new research has analyzed seismic waves from repeating earthquakes over the last six decades.
    • It shows that- the inner core started rotating slightly faster than the rest of the planet in the early 1970s, the study said.
    • But it had been slowing down before coming in sync with Earth’s rotation around 2009.

    What made the core spin slower?

    • So far there is little to indicate that what the inner core does has many effects on surface dwellers.
    • The researchers said this rotation timeline roughly lines up with changes in what is called the “length of day”— small variations in the exact time it takes Earth to rotate on its axis.
    • But the researchers said they believed there were physical links between all of Earth’s layers, from the inner core to the surface.

  • Aditya-L1: India’s first mission to Sun to be launched soon

    aditya

    The Indian Space Research Organisation (ISRO) is planning to launch the Aditya-L1 mission by June or July this year.

    What is Aditya-L1 Mission?

    • ISRO categorizes Aditya L1 as a 400 kg-class satellite that will be launched using the Polar Satellite Launch Vehicle (PSLV) in XL configuration.
    • It will observe the Sun from a close distance, and try to obtain information about its atmosphere and magnetic field.
    • The space-based observatory will have seven payloads (instruments) on board to study the Sun’s corona, solar emissions, solar winds and flares, and Coronal Mass Ejections (CMEs), and will carry out round-the-clock imaging of the Sun.

    L1: Behind the name

    • L1 refers to Lagrangian/Lagrange Point 1, one of five points in the orbital plane of the Earth-Sun system.
    • Lagrange Points, named after Italian-French mathematician Josephy-Louis Lagrange, are positions in space where the gravitational forces of a two-body system (like the Sun and the Earth) produce enhanced regions of attraction and repulsion.
    • The L1 point is about 1.5 million km from Earth, or about one-hundredth of the way to the Sun.

    Major payloads

    • In total Aditya-L1 has seven payloads, of which the primary payload is the Visible Emission Line Coronagraph (VELC), designed and fabricated by the Indian Institute of Astrophysics, Bengaluru.
    • The satellite carries additional six payloads-
    1. SUIT, the solar ultraviolet imaging telescope
    2. ASPEX (Aditya Solar Wind Particle Experiment),
    3. PAPA (Plasma Analyser Package for Aditya),
    4. SoLEXS (Solar Low Energy X-ray Spectrometer),
    5. HEL1OS (High Energy L1 Orbiting X-ray spectrometer) and
    6. Magnetometer — with enhanced science scope and objectives possible by extensive remote and in-situ observation of the sun.

    Why is studying the Sun important?

    (1) To understand space weather

    • To learn about and track Earth-directed storms, and to predict their impact, continuous solar observations are needed.
    • Every storm that emerges from the Sun and heads towards Earth passes through L1, and a satellite placed in the halo orbit around L1 of the Sun-Earth system has the major advantage of continuously viewing the Sun without any occultation/eclipses.

    (2) Observing corona

    • The VELC payload will be able to observe the corona continuously and the data provided by it is expected to answer many outstanding problems in the field of solar astronomy.
    • No other solar coronagraph in space has the ability to image the solar corona as close to the solar disk as VELC can.
    • It can image it as close as 1.05 times the solar radius.
    • It can also do imaging, spectroscopy, and polarimetry at the same time, and can take observations at a very high resolution (level of detail) and many times a second.

    Why are solar missions challenging?

    • Distance: What makes a solar mission challenging is the distance of the Sun from Earth (about 149 million km on average, compared to the only 3.84 lakh km to the Moon).
    • Heat: More importantly the super-hot temperatures and radiations in the solar atmosphere make it difficult to study.

    Major missions to Sun till now

    • NASA’s Parker Solar Probe has already gone far closer — but it will be looking away from the Sun.
    • The earlier Helios 2 solar probe, a joint venture between NASA and space agency of erstwhile West Germany, went within 43 million km of the Sun’s surface in 1976.

  • New T+1 Settlement Cycle comes into effect

    settlement

    After China, India will become the second country in the world to start the ‘trade-plus-one’ (T+1) settlement cycle in top-listed securities today.

    What’s the T+1 settlement plan?

    • The T+1 settlement cycle means that trade-related settlements must be done within a day, or 24 hours, of the completion of a transaction.
    • For example, under T+1, if a customer bought shares on Wednesday, they would be credited to the customer’s demat account on Thursday.
    • This is different from T+2, where they will be settled on Friday.
    • As many as 256 large-cap and top mid-cap stocks, including Nifty and Sensex stocks, will come under the T+1 settlement from Friday.

    What was the earlier settlement system?

    • Until 2001, stock markets had a weekly settlement system.
    • The markets then moved to a rolling settlement system of T+3, and then to T+2 in 2003.
    • In 2020, Sebi deferred the plan to halve the trade settlement cycle to one day (T+1) following opposition from foreign investors.

    What are the benefits of T+1?

    • T+1 system brings operational efficiency, faster fund remittances, share delivery, and ease for stock market participants.
    • In the T+1 format, if an investor sells a share, she will get the money within a day, and the buyer will get the shares in her demat account also within a day.
    • The shorter trade settlement cycle augurs well for the Indian equity markets from a liquidity perspective.
    • This will also help investors in reducing the overall capital requirements with the margins getting released on T+1 day, and in getting the funds in the bank account within 24 hours of the sale of shares.
    • The shift will boost operational efficiency as the rolling of funds and stocks will be faster.

    Issues with T+1 system

    • T+1 is being implemented despite opposition from foreign investors.
    • The United States, United Kingdom and Eurozone markets are yet to move to the T+1 system.

    Why are foreign investors opposed?

    • Foreign investors have some operational issues as they operate from different geographies.
    • Among the issues raised by them were time zone differences, information flow processes, and foreign exchange problems.
    • Foreign investors said they would also find it difficult to hedge their net India exposure in dollar terms at the end of the day under the T+1 system.

  • Ideal Train Profile: Railways’ AI-based project to shorten ticket waitlists

    The Indian Railways has concluded the trial of an Artificial Intelligence (AI) program it built to fix a perennial issue — long waiting lists for tickets.

    Ideal Train Profile

    • Ideal Train Profile was made by Railways’ in-house software arm Centre for Railway Information Systems (CRIS).
    • It was fed with information like how millions of passengers booked tickets on these trains, which origin-destination pairs were a hit and which were flops at what time of the year, which seats remained vacant for what portion of a journey, etc.
    • This project has been in the works for the past two years, wherein the AI has been “taught” ticket booking data and trends of the past few years.
    • It has come up with the best possible combination of how many berths to keep for which sectors and at what time.
    • The combination of “training data” the AI has been fed goes back three years.

    Significance of the project

    • The AI-driven program has, for the first time, allocated vacant berths in over 200 trains in such a way that fewer people need to turn away without a confirmed ticket.
    • The waiting lists on these trains, as a result, have seen a curtailment.

    Need for AI in ticket booking

    • Currently, the passenger is handed out a wait-listed ticket and asked to wait until four hours prior to departure, when the final seat chart is prepared, to see if she made the list.
    • This is because a large number of berths are earmarked for various quotas and various origin-destination combinations of the train’s routes.
    • If there are 60 halts in a long-distance train, then there are 1,800 possible ticket combinations of origin and destination.
    • If there are 10 halts, there are typically about 45 ticket combinations and so on.
    • The Ideal Train Profile’s AI tells the Passenger Reservation System how best to give out confirmed tickets and for which sectors.

    Way forward

    • The AI does data-driven remote location selection, completely automates the process of quota distribution, and suggests optimal quota for different ticket combinations based on historical demand.
    • The project has got the Railway Board excited about the possibility of how it can manage busy season rush, when the demands of confirmed tickets are at a peak.
    • So the coming summer vacation season will be the first big test for the new system.
