    Froth formation in Yamuna

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Froth Formation

    Mains level: Not Much

    The visuals of devotees taking a dip in the froth-filled waters of the Yamuna River sent chills down the spine of the residents of Delhi.

    What is Froth Formation?

    • This is a phenomenon that takes place on many lakes and streams.
    • Foam bubbles are produced when organic matter decomposes.
    • These foam-producing molecules have one end that repels water and another that attracts water and they work to reduce the surface tension on the surface of the water.
    • These foam bubbles are lighter than water, so they float on the surface as a thin film that gradually accumulates.

    What causes the froth?

    • The presence of phosphates and surfactants in untreated sewage from Delhi, Haryana and Uttar Pradesh is a major reason behind frothing.
    • While these two components comprise of 1 per cent, the remaining 99 percent is air and water.

    What are the sources of pollution that cause foam formation?

    • Untreated sewage may contain soap-detergent particles.
    • The other sources are industrial effluents, organic matter from decomposing vegetation, and the presence of filamentous bacteria.
    • The pollution from the sugar and paper industries in Uttar Pradesh also causes pollution in the Yamuna.

    What are its health hazards?

    • Short-term exposure can lead to skin irritation and allergies.
    • If ingested, these chemicals may cause gastrointestinal problems and diseases like typhoid.
    • Long-term exposure to heavy metals in industrial pollutants can cause neurological issues and hormonal imbalances.

  • Modern Indian History-Events and Personalities

    Life, work and legend of Adi Shankaracharya

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Adi Shankaracharya, Advaita Vedanta Philisophy

    Mains level: Indian Schools of Philosophy

    PM has unveiled a 12-foot statue of Adi Shankaracharya at Kedarnath, where the acharya is believed to have attained samadhi at the age of 32 in the ninth century.

    Adi Shankaracharya (788-820 AD)

    • Adi Shankaracharya was an Indian philosopher and theologian whose works had a strong impact on the doctrine of Advaita Vedanta.
    • He founded mathas, which are believed to have helped in the historical development, revival and propagation of his philosophy.
    • The story recounted today has been reconstructed from multiple Shankaravijayas (Conquests of Shankara) written over the centuries.

    Birth and death

    • He is said to have been born in Kaladi village on the bank of the Periyar, the largest river in Kerala.
    • He is believed to have attained samadhi at Kedarnath; however, Kanchi and Thrissur are also talked about as places where Adi Shankara spent his last days.

    His literary works

    • Adi Shankara is generally identified as the author of 116 works.
    • Among them the celebrated commentaries (bhashyas) on 10 Upanishads, the Brahmasutra and the Gita, and poetic works including Vivekachudamani, Maneesha Panchakam, and Saundaryalahiri.
    • He composed the Kanakadhara Stotram, following which there was a rain of golden amlas, which brought prosperity to the household.
    • It has also been claimed that Adi Shankara composed texts like Shankarasmrithi, which seeks to establish the social supremacy of Nambuthiri Brahmins.
    • His great standing is derived from his commentaries of the prasthanatrayi (Upanishads, Brahmasutra and Gita), where he explains his understanding of Advaita Vedanta.

    His philosophy: Advaita Vedanta

    • Advaita Vedanta articulates a philosophical position of radical nondualism, a revisionary worldview which it derives from the ancient Upanishadic texts.
    • According to this, the Upanishads reveal a fundamental principle of nonduality termed brahman’, which is the reality of all things.
    • Advaitins understand brahman as transcending individuality and empirical plurality.
    • They seek to establish that the essential core of one’s self (atman) is brahman. It is pure non-intentional consciousness.
    • It is one without a second, nondual, infinite existence, and numerically identical with brahman.
    • This effort entails tying a metaphysics of brahman to a philosophy of consciousness.

    Do you know?

    There are six major schools of Vedic philosophy—Nyaya, Vaisheshika, Samkhya, Yoga, Mīmāṃsā and Vedanta, and five major heterodox (sramanic) schools—Jain, Buddhist, Ajivika, Ajñana, and Charvaka.

    Shankara’s contested legacy

    • Custodians of the caste system cite from Shankara’s commentaries to justify the unequal and unjust social order.
    • It is argued that the Advaita Vedanta borrowed the categories of Buddhist thinkers and called him the Prachhanna Buddha (Buddha in disguise).
    • Sri Narayana Guru offered a radical reading of Advaita Vedanta to dismantle the theory and praxis of caste.

    His political appropriation

    • His works transcends the political boundaries of his time.
    • The mathas are believed to have established in Sringeri, Dwaraka, Puri, and Joshimath for the spread of Advaita Vedanta.
    • They are seen as custodians of Hinduism, and Shankara’s digvijaya (conquest) often interpreted as a near nationalistic project where faith, philosophy and geography are yoked together to imagine a Hindu India.

    Try this PYQ:

    Q. Which one of the following pairs does not form part of the six systems of Indian Philosophy?

    (a) Mimamsa and Vedanta

    (b) Nyaya and Vaisheshika

  • Nuclear Energy

    Iran has enriched over 210 kg of Uranium to 20%

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Uranium enrichment

    Mains level: Not Much

    Iran’s atomic agency has said that its stockpile of 20% enriched uranium has reached over 210 kilograms, the latest defiant move ahead of upcoming nuclear talks with the West.

    What is Uranium Enrichment?

    • It is a process that is necessary to create an effective nuclear fuel out of mined uranium.
    • It involves increasing the percentage of uranium-235 which undergoes fission with thermal neutrons.
    • Nuclear fuel is mined from naturally occurring uranium ore deposits and then isolated through chemical reactions and separation processes.
    • These chemical processes used to separate the uranium from the ore are not to be confused with the physical and chemical processes used to enrich the uranium.

    Why is enrichment carried out?

    • Uranium found in nature consists largely of two isotopes, U-235 and U-238.
    • Natural uranium contains 0.7% of the U-235 isotope.
    • The remaining 99.3% is mostly the U-238 isotope which does not contribute directly to the fission process (though it does so indirectly by the formation of fissile isotopes of plutonium).
    • The production of energy in nuclear reactors is from the ‘fission’ or splitting of the U-235 atoms since it is the main fissile isotope of uranium.
    • Naturally occurring uranium does not have a high enough concentration of Uranium-235 at only about 0.72% with the remainder being Uranium-238.

    Centre cuts Excise Duty on Petrol and Diesel

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Excise duty

    Mains level: Petroleum pricing in India

    The Government has finally reduced fuel prices by slashing excise duties on petrol and diesel by ₹5 and ₹10 per litre respectively.

    What is Excise Duty?

    • Excise duty is a form of tax imposed on goods for their production, licensing and sale.
    • It is the opposite of Customs duty in sense that it applies to goods manufactured domestically in the country, while Customs is levied on those coming from outside of the country.
    • At the central level, excise duty earlier used to be levied as Central Excise Duty, Additional Excise Duty, etc.
    • Excise duty was levied on manufactured goods and levied at the time of removal of goods, while GST is levied on the supply of goods and services.

    Purview of excise duty

    • The GST introduction in July 2017 subsumed many types of excise duty.
    • Today, excise duty applies only on petroleum and liquor.
    • Alcohol does not come under the purview of GST as exclusion mandated by constitutional provision.
    • States levy taxes on alcohol according to the same practice as was prevalent before the rollout of GST.
    • After GST was introduced, excise duty was replaced by central GST because excise was levied by the central government.
    • The revenue generated from CGST goes to the central government.

    Types of excise duty in India

    Before GST, there were three kinds of excise duties in India.

    (1) Basic Excise Duty

    • Basic excise duty is also known as the Central Value Added Tax (CENVAT).
    • This category of excise duty was levied on goods that were classified under the first schedule of the Central Excise Tariff Act, 1985.
    • This duty applied on all goods except salt.

    (2) Additional Excise Duty

    • Additional excise duty was levied on goods of high importance, under the Additional Excise under Additional Duties of Excise (Goods of Special Importance) Act, 1957.
    • This duty was levied on some special category of goods.

    (3) Special Excise Duty

    • This type of excise duty was levied on special goods classified under the Second Schedule to the Central Excise Tariff Act, 1985.
    • Presently the central excise duty comprises of a Basic Excise Duty, Special Additional Excise Duty and Additional Excise Duty (Road and Infrastructure Cess) on auto fuels.

    Present taxation of Fuels

    • Currently, taxes on petroleum products are levied by both the Centre and the states.
    • While the Centre levies excise duty, states levy value-added tax (VAT).
    • For instance, VAT on petroleum products is as high as 40% in Maharashtra, contributing over ₹25,000 crores annually.
    • By being able to levy VAT on these products, the state governments have control over their revenues.
    • When a national GST subsumed central taxes such as excise duty and state levies like VAT on July 1, 2017, five petroleum goods – petrol, diesel, ATF, natural gas and crude oil – were kept out of its purview.

    Gujarat grants Parole to Prisoners as Diwali gift

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Parole and Furlough

    Mains level: Prison reforms in India

    The Gujarat government has decided to grant 15-day parole to prisoners above 60 years of age and women prisoners, except those booked in serious offences, as a ‘Diwali gift’.

    What is Parole?

    • Furlough and parole envisage a short-term release from custody, both aimed as reformative steps towards prisoners.
    • Parole is granted to meet a “specific exigency” and cannot be claimed as a matter of right.
    • Both provisions are subject to the circumstances of the prisoner, such as jail behaviour, the gravity of offences, sentence period and public interest.

    How is it different from Furlough?

    • Furlough may be granted without any specific reason after a convict spends a stipulated number of years.
    • It is a matter of right although cannot be claimed as an ‘absolute legal right’.

    Is ‘parole as Diwali gift’ an extraordinary move?

    • The state governments often take a compassionate view on applications for parole during festivals of Diwali, Rakshabandhan, etc.
    • The legislature/politicians do not have direct powers to grant parole on suo-motu cognizance.
    • The announcement only indicates that prisoners will have to make applications to the authorities concerned, which in turn will be considered with leniency and expeditiously.
    • The applications will, however, be subject to scrutiny and the prisoners’ conduct and gravity of their offence.

    Who can opt for parole and how?

    • The provision of parole is available to convicts found guilty by a court and such a prisoner.
    • The prisoner’s relative/legal aid may submit an application to the prison superintendent.
    • He/she in turn forwards the application to the ‘competent authority’, often under the jurisdiction of district magistrate concerned and comprising prison and police authorities, to sanction release.
    • After due verification of reasons and prisoner’s conduct by the competent authority, an order for grant of release on parole will be issued.
    • In case of rejection of the said application, a convict may approach the High Court.

    Duration of Parole

    • The Prison rules state that parole period may be granted for not more than 30 days.
    • The competent authority may exercise its discretion in case of serious illnesses or death of “nearest relative such as mother, father, sister, brother, children, spouse of the prisoner, or in case of natural calamity.”
    • Parole or extension of parole cannot be granted without a report of the police
    • Apart from the remedy to approach a high court for parole in case of a rejected application, a prison can also approach the high court directly in case of an extraordinary emergency.

  • RBI Notifications

    RBI issues revised Prompt Corrective Action (PCA) framework

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: PCA framework

    Mains level: Paper 3- PCA framework

    The RBI has issued a revised Prompt Corrective Action (PCA) framework for banks to enable supervisory intervention at “appropriate time” and also act as a tool for effective market discipline.

    What is the PCA framework?

    • Prompt Corrective Action Framework refers to the central bank’s watchlist of weak banks.
    • The regulator imposes restrictions like curbs on lending on such banks.
    • The PCA Framework applies only to commercial banks and does not cover cooperative banks and non-banking financial companies.

    When was PCA introduced?

    • The RBI’s PCA Framework was introduced in December 2002 as a structured early intervention mechanism along the lines of the US Federal Deposit Insurance Corporation’s PCA framework.
    • The last PCA Framework was issued by the RBI on April 13, 2017, and implemented with respect to banks’ financials as of March 31, 2017.

    Latest PCA norms

    • The revised PCA framework will be effective from January 1, 2022.
    • Capital, asset quality and leverage will be the key areas for monitoring in the revised framework.
    • That apart, RBI has also revised the level of shortfall in total capital adequacy ratio that would push the lender to “risk threshold three” category.

    When exactly does a bank fall into this list?

    • The RBI has specified certain regulatory trigger points with respect to three parameters for the initiation of the process:
    • Capital-to-risk weighted assets ratio (CRAR): It is a measure of a bank’s capital to ensure that it can absorb a reasonable amount of loss and complies with statutory Capital requirements.
    • Net Non-Performing Assets (NPA)
    • Return on assets (RoA): It is an indicator of how well a company utilizes its assets in terms of profitability.

    What are the trigger points on capital and how does a breach invite action?

    1. CRAR

    • If CRAR falls to less than 9 percent, the RBI asks banks to submit a capital restoration plan, restricts new businesses and dividend payments.
    • The RBI also orders recapitalisation, restrictions on borrowings from the inter-bank market, reduction of stake in subsidiaries and reduction of exposure to sensitive sectors.
    • Such sectors include the capital markets, real estate or investments in non-statutory liquidity ratio securities.
    • If CRAR is less than 6 percent but equal to or more than 3 percent, the RBI could take additional steps if the bank fails to submit a recapitalisation plan.

    2. NPA levels

    • If net NPAs rise beyond 10 percent but are less than 15 percent, a special drive to reduce bad loans and contain the generation of fresh NPAs begins.
    • The RBI reviews the bank’s loan policy and takes steps to strengthen credit-appraisal skills.

    3.Return on assets

    • If RoA is less than 0.25 percent, restrictions on accessing/renewing costly deposits and CDs kick in and the RBI bars the bank from entering new lines of business.
    • The bank’s borrowings from the inter-bank market, making dividend payments and increasing staff will be restricted.

    Significance of PCA

    • The financial health of a bank: Essentially PCA helps RBI monitor key performance indicators of banks, and taking corrective measures, to restore the financial health of a bank.
    • Averting a crisis: PCA is intended to help alert the regulator as well as investors and depositors if a bank is heading for trouble. The idea is to head off problems before they attain crisis proportions.

    • The guide has been drawn from years of experience of the organization while rescuing 25 Ganges River Dolphins (GRDs) stranded in irrigation canals.

    Various threats

    • They often accidentally enter canal channels in northern India and are often entrapped, and die as they are unable to swim up against the gradient.
    • They are eventually harassed by the locals.
    • Opportunistic poaching for meat and oil in certain pockets of the country is another big threat.
