    What are Supplementary Grants?

    Supplementary Grants

    Lok Sabha recently held voting on supplementary demands for grants for Jammu and Kashmir and passed the proposals on voice vote.

    What are Supplementary Grants?

    • The additional grant required to meet the required expenditure of the government is called Supplementary Grants.
    • When grants, authorised by the Parliament, fall short of the required expenditure, an estimate is presented before the Parliament for Supplementary or Additional grants.
    • These grants are presented and passed by the Parliament before the end of the financial year.
    • When actual expenditure incurred exceeds the approved grants of the Parliament, the Ministry of Finance and Ministry of Railways presents a Demand for Excess Grant.

    How it works?

    • The Comptroller and Auditor General of India bring such excesses to the notice of the Parliament.
    • The Public Accounts Committee examines these excesses and gives recommendations to the Parliament.
    • The Demand for Excess Grants is made after the actual expenditure is incurred and is presented to the Parliament after the end of the financial year in which the expenses were made.

    [pib] Flexi Fare System

    During the eight months period from 1st July 2019 to 29th February 2020, approximately 28.93 Lakh berths remained vacant in Rajdhani, Shatabdi and Duronto type trains having Flexi fare.

    What is Flexi Fare System?

    • The flexi-fare scheme was introduced by the IRCTC in 2016 for the 142 “premium trains” such as Shatabdi, Rajdhani, and Duronto (now Vande Bharat Exp. as well).
    • Under this dynamic pricing system, the base fare increases by 10% with every 10% of berths sold, with a limit set at 1.5 times the original price.
    • The scheme was applicable to all classes, except AC first class and executive class. The pricing system is still in force.

    Reasons for flexi fares:

    1. Indian Railways run about 12900 passenger trains per day and the railways is losing around more than 40% of what they spend on passenger trains.
    2. The trains like Rajdhani are the ones in which the elite class prefers to travel. So, some revenue can be garnered from them.
    3. The cost of service is almost double of what is being charged from the passengers.
    4. Freight business is already very expensive in India as compared to other countries in the world. Therefore, a further increase in this area is not feasible.

    Issues with the system

    • After the introduction of Flexi-fares, the railways lost 700,000 passengers in just 11 months while the additional revenue earned as a result of the scheme was ₹ 552 crore.
    • While drawing upon the fundamentals of dynamic pricing, what Indian Railways failed to introduce was a simple principle that Flexi-fares work ways, hikes, and declines.
    • The railways model just focused on increasing fares with no provision for a decrease in price when demand is low.
    • While half of the decision-makers in the Railway Board support it, half of them oppose it stating that what the railways require is an increase in ticket prices across the board.

    [pib] GreenCo Rating System

     

     

    The Union Ministry of Railways has informed about the applications of Greenco Ratings on Workshops and Production Units of Indian Railways.

    GreenCo Ratings

    • GreenCo Rating is the “first of its kind in the World” holistic framework that evaluates companies on the environmental friendliness of their activities using life cycle approach.
    • Implementation of GreenCo rating provides leadership and guidance to companies on how to make products, services and operations greener.
    • It is developed by Confederation of Indian Industry’s (CII) Sohrabji Godrej Green Business Centre.
    • It has been acknowledged in India’s Intended Nationally Determined Contribution (INDC) document, submitted to UNFCCC in 2015.
    • GreenCo rating is applicable to both manufacturing facilities and service sector units.
    • The rating is implemented at unit or facility level. The unit or facility has to be in operation for a minimum period of 3 years. In case of new plants/ facilities minimum 2 years operation is required.

    Utility

    It helps the industrial units in identifying and implementing various possible measures in terms of energy conservation, material conservation, recycling, utilization of renewable energy, GHG reduction, water conservation, solid and liquid waste management, green cover etc.

    [pib] Friction-reducing Nanocomposite Coatings

    A group of scientists at the International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI) have developed a process for size-selective deposition of nanocomposite coatings which can reduce friction of these dynamic systems.

    What are Nanocomposites?

    • Nanocomposite coatings are formed by mixing two or more dissimilar materials at nanoscale to improve the physical, chemical and physicochemical properties of the new materials.
    • The scientists have found that nickel tungsten-based coatings with infusion of particular sized Silicon Carbide (SiC) submicron particles using a pulsed electroplating can provide an excellent combination of wear and corrosion resistance.

    Applications

    • Many aerospace, defence, automobile, space devices need to reduce friction, wear, and tear to enhance the life of components.
    • Lubricating these dynamic systems add to the cost, complexity, and weight of these systems.
    • The coating could help in reducing the friction of such devices.

    [pib] Potential Fishing Zone (PFZ) Advisories

    The Indian National Centre for Ocean Information Services (INCOIS), Hyderabad has reported that Oceansat Satellite data from ISRO are used to prepare the PFZ advisories on the potential rich fishing areas and provide to the sea faring fishermen in all states.

    Potential Fishing Zone (PFZ)

    • This is the first advisory service started by INCOIS. The backbone of this service is the real-time data for ocean color and SST provided by the OCEANSAT and NOAA respectively.
    • This service was started because there was a need to identify the potential fishing zones to help the fishermen to get better catch while they were at the sea.
    • This service was started by the Ministry of Earth Sciences with the help of the Department of Space and several institutions under the Ministry of Agriculture.

    How it works?

    • This service makes use of parameters such as sea surface temperature and chlorophyll content provided by NOAA-AVHRR and Oceancolor satellites.
    • Features such as oceanic fronts, Meandering Patterns, Eddies, Rings, Up Welling areas etc. are identified sites for fish accumulation.
    • These features can easily be identified from Sea Surface Temperature and Chlorophyll data.
    • The availability of Chlorophyll from OCEANSAT and MOdDIS has further enriched these advisories in the recent years.
    • Hence, PFZ advisories have helped the fishing community to locate the fishing zones with accuracy.

    Special advisories for fisherman

    • Another feature of PFZ service is the generation of species-specific advisory to enable the fishermen folk to distinguish between the exploited and under-exploited species in the potential fishing zones.
    • This enables them to have sustainable fishery management by targeting only the under-exploited species in the fishing zones.
    • This approach enables them to avoid fishing the over-exploited species over and over again.
  • Issues related to Economic growth

    Triggering a Global Financial Crisis

    Context

    Although we could not have predicted it, Covid-19 was not the reason, but just the trigger for the ongoing financial crash as all we needed was the proverbial straw to break the finance sector’s back

    Economic sudden stop

    • Not just any trigger: Covid-19 was not just any trigger as it gave birth to the concept of the economic “sudden stop.” When the global equity markets dropped on 31 January 2020 following the WHO declaration of the Public Health Emergency of International Concern, El-Erian (2020) warned the investors on 2 February 2020 that they should snap out of the “buy the dip” mentality.
      • Pointing out two vulnerabilities, namely structurally weak global growth and less effective central banks, he introduced the concept of “sudden stop” economic dynamics.
    • What is sudden stop? It can be considered as an abrupt onset of a deep recession.
      • Supply and demand shock: In the case of Covid-19, it is a sudden stop of economic activity resulting in supply and demand shocks to the global economy as major cities in infected countries, more than 100 and counting, are put on lockdown.
      • And, add to that the deepening oil price war between Russia and Saudi Arabia.
    • On 8 March 2020 in New York, the futures markets opened and oil futures (both Brent and WTI) are trading about 21% down, gold is above $1,700 per ounce, and all United States (US) equity index futures are trading about 4% down.
    • Long terms treasury yield at historical lows: What is worse is that with the long-term US Treasury yields at their historical lows (10-year yield below 0.5% and 30-year yield below 1%), the capital markets are frozen (not to mention many oil projects that will go bust at these prices).

    Disorderly non-financial private sector debt leading to dire consequences

    • A disorderly global non-financial private sector debt deleveraging, which is likely to lead to deep global debt deflation, followed by a recession (and possibly a depression).
      • Which could result in creating financial and economic instabilities, and further tensions in international relations with dire consequences for emerging and developing countries, not to mention developed countries.
    • Difference in developed and developing countries debts: While in developed and high-income developing countries, the non-financial private sector is more over-indebted, in middle-income and low-income developing countries, the public sector is more over-indebted.
    • Impact on developed economies: Given that the global non-financial private sector debt deleveraging has already started, the public sector debts of the developed and high-income developing countries will also go up and the governments’ ability to rescue their economies will also decline in these countries.
    • Impact on funding for climate change: Furthermore, this will severely constrain the governments’ ability to spend on climate change-related projects to address the potentially catastrophic effects for many years to come, diminishing our hopes to make the necessary investments and innovations to address the now existential climate crisis on time will diminish.
    • The corona factor: The measures we have to take to control the spread of Covid-19 before a cure is found will further challenge the financial system, as people stop earning an income and businesses go bankrupt.

    Way forward

    • Three authorities solution: In the suggested framework, there would be three authorities to maintain a deposit account at the central bank in each country
      • 1. A deleveraging authority for leverage reduction.
      • 2. Lastenausgleich (based on German Currency Reforms) authority for capital levies.
      • 3. Climate authority for financing needs in developing national climate plans.
      • These national authorities should be globally coordinated through the appropriate United Nations agencies.
    • Control the three authorities: The Lastenausgleich authority would be under the finance ministry, whereas the deleveraging and climate authorities would be not-for-profit corporations promoted by the government.
    • Capitalisation issue: The government would capitalise the deleveraging and climate authorities by the Treasury-issued zero-coupon perpetual bonds.
    • The deleveraging authority would then sell its equalisation claims to the central bank in exchange for an increased balance in its deposit account at the bank, while the climate authority would wait until the deleveraging concludes.
      • Further, the climate authority would not be allowed to open deposit accounts to its borrowers to ensure that it would be a pure financial intermediary, not a bank.
    • Framework: Assuming that a globally agreed-upon debt reduction percentage that would bring the global non-financial sector leverage well under 100% is determined and that all countries agree to act simultaneously, the framework is as follows
      • (i) the financial institutions comprising the banks and non-bank financial institutions (NBFIs) write down all the loans and debt securities on both sides of their balance sheets by the required percentage;
      • (ii) the deleveraging authority compensates the banks and NBFIs for the loss if any; and
      • (iii) the deleveraging authority pays each qualified resident their allocated amount less than the debt relief if any.
      • If an NBFI gain after the above debt reduction, it should owe equalisation liabilities to the deleveraging authority of its jurisdiction.
      • Note that as all debts mean all debts, public sector debts will also be written down by the same percentage except the official debts of the sovereigns that fall out of the scope of our proposed framework and should be handled by other means.
    • After deleveraging: After deleveraging the balance of the deleveraging authority account at the central bank goes down whereas the total balance of the bank accounts (reserves) at the central bank goes up by the total payment made by the deleveraging authority.
      • Hence, the base money goes up by the total payment of the deleveraging authority.
      • Since NBFIs and residents cannot maintain deposit accounts at the central bank, they have to be paid through a bank which creates deposits for the NBFIs and residents against reserves.
      • Hence, the broad money goes up by the amount of the payment to the NBFIs and residents.
    • Issue of multi-currency balance sheet: One issue is that in many countries, the bank and NBFI balance sheets are multi-currency balance sheets.
      • However, the deleveraging authority payments are in domestic currency, which may create currency risk for some banks and NBFIs.
      • Backed by the central banks, the globally coordinated national deleveraging authorities should stand ready to intervene to avoid potential crises.
    • Condition to spend on climate bonds: The authorities would require their domestic banks and other financial institutions to spend an internationally agreed-upon percentage of their newly found money, if any, after the deleveraging on the interest-bearing, finite-maturity bonds the national climate authorities would issue.
      • Since the promoter of the climate authority is the government, the bonds of the climate authority would have the same credit with the government bonds, and the central bank would accept the climate authority bonds in its open market operations.
    • Climate authority bonds as reserves: Therefore, the climate authority bonds would be the main tool to manage the reserves and deposits created through the equalisation claims.
      • In addition, the climate authority bonds could be used for the greening of the financial system through the investment of foreign exchange reserves of the central banks proposed by the Bank of International Settlements (BIS 2019).
    • Progressive wealth tax collection: Lastly, equipped with a “globally coordinated wealth registry” (Stiglitz et al 2019), the Lastenausgleich authorities would collect progressive wealth taxes from the owners of real and non-debt financial assets for the equalisation of burdens.
      • While a part of these taxes could be used to retire some of the equalisation claims and the corresponding reserves and deposits created in the deleveraging process, another part could be transferred to the climate authorities, and the rest could be spent in the interests of the society.
  • Judicial Reforms

    The Hidayatullah example

    Context

    It has been recently announced that the President has nominated former Chief Justice of India, Ranjan Gogoi, to the Rajya Sabha. However, the time has come for us to ask a difficult question: Should judges stop accepting post-retirement jobs offered by the government, at least for a few years after retiring, because accepting such posts could undermine the independence of the judiciary?

    The issue of post-retirement employment of the judges

    • Retirement age of judges: Unlike federal judges in the US, judges in India do not hold office for life. They remain in office until they reach the retirement age — 65 for Supreme Court judges and 62 for high court judges.
    • Protection against arbitrary removal: These judges do not hold their offices at the “pleasure” of the President. In other words, they cannot be arbitrarily removed by the government once they are appointed, and can only be impeached by a supermajority of both houses of Parliament “on the ground of proved misbehaviour or incapacity”.
    • Difficult impeachment process: The impeachment process is a very difficult one and never in the history of independent India has a judge been impeached, though attempts have sometimes been made to do so. Judges, therefore, enjoy security of tenure while holding office, which is essential for maintaining judicial independence.
    • How retirement of judges could undermine judicial independence? The retirement of judges threatens to undermine judicial independence.
      • This is because some judges — not all — are offered post-retirement employment by the government. It is often feared that a judge who is nearing retirement could decide cases in a manner that pleases the government in order to get a favourable post-retirement position.

    Not an unprecedented move

    • Former CJI Gogoi is certainly not the first retired judge to be appointed to political office.
    • In 1952, Justice Fazl Ali was appointed the Governor of Orissa, shortly after retiring from the Supreme Court.
    • In 1958, Chief Justice M C Chagla resigned from the Bombay High Court in order to become India’s Ambassador to the US at Prime Minister Nehru’s invitation.
    • In April 1967, Chief Justice Subba Rao resigned from the Supreme Court to contest elections for President.
    • In 1983, Justice Baharul Islam resigned from the Supreme Court to contest as a Congress (I) candidate for a Lok Sabha seat, after ruling in favour of Bihar’s Congress (I) chief minister, Jagannath Mishra, in a controversial case where Mishra had been accused of criminal wrongdoing and misuse of office.
    • In more recent times, Chief Justice P Sathasivam was appointed the Governor of Kerala. There are many other such examples.

    Why restrictions about employment were not included in the Constitution?

    • The Constitution provides that a retired Supreme Court judge cannot “plead or act in any court or before any authority within the territory of India”.
    • Constituent assembly debate: In the Constituent Assembly, K T Shah, an economist and advocate, suggested that high court and Supreme Court judges should not take up an executive office with the government, “so that no temptation should be available to a judge for greater emoluments, or greater prestige which would in any way affect his independence as a judge”.
      • However, this suggestion was rejected by B R Ambedkar because he felt that the “judiciary decides cases in which the government has, if at all, the remotest interest, in fact, no interest at all”.
    • Government is the largest litigant in the courts: In Ambedkar’s time, the judiciary was engaged in deciding private disputes and rarely did cases arise between citizens and the government. “Consequently”, said Ambedkar, “the chances of influencing the conduct of a member of the judiciary by the government are very remote”.
      • This reasoning no longer holds today because the government is one of the largest litigants in the courts.

    Question of independence of the judiciary

    • The question of constitutional propriety: In the words of India’s first Attorney General, M C Setalvad, all this raises “a question of constitutional propriety” relating to the independence of the judiciary.
    • After all, could the government not use such tactics to reward judges who decide cases in its favour?
    • Public perception of compromised judiciary: Further, if a judge decides highly controversial and contested cases in favour of the government and then accepts a post-retirement job, even if there is no actual quid pro quo, would this not lead to the public perception that the independence of the judiciary is compromised?

    Law Commission recommendations

    • In its 14th report in 1958, the Law Commission noted that retired Supreme Court judges used to engage in two kinds of work after retirement:
      • Firstly, “chamber practice” (a term which would, today, mean giving opinions to clients and serving as arbitrators in private disputes).
      • Secondly, “employment in important positions under the government”.
    • The Law Commission frowned upon chamber practice but did not recommend its abolition.
    • Ban on post-retirement government employment: It strongly recommended banning post-retirement government employment for Supreme Court judges because the government was a large litigant in the courts.
      • The Commission’s recommendations were never implemented.

    Conclusion

    It is about time that we start expecting the judges of our constitutional courts to follow CJI Hidayatullah’s excellent example in which he had accepted government job only after the cooling period of several years.

     

     

  • Foreign Policy Watch: India-SAARC Nations

    A revival of multilateralism, steered by India

    Context

    A leadership role by India in mobilising world collaboration would be in keeping with its traditional activism globally.

    Challenges and two aspects associated with it.

    • The COVID-19 pandemic has brought out in sharp relief the compelling reality that has been staring us in the face for the past several years.
    • This reality has two aspects.
    • First aspect: That most challenges confronting the world and likely to confront it in the future are cross-national in character. They respect no national boundaries and are not amenable to national solutions.
    • Second aspect: These challenges are cross-domain in nature, with strong feedback loops.
      • A disruption in one domain often cascades into parallel disruptions in other domains.
      • For example, the use of chemical fertilizers and toxic pesticides may promote food security but have injurious health effects, undermining health security.
      • Whether at the domestic or the international level, these inter-domain linkages need to be understood and inform policy interventions. The UN Sustainable Development Goals (SDGs) reflect this awareness.

    Rise in nationalism

    • Need for multilateral approach: The intersection of cross-national and cross-domain challenges demand multilateral approaches.
      • They require empowered international institutions of governance.
      • Underlying these must be a spirit of internationalism and solidarity, a sense of belonging to common humanity.
    • Moving in the reverse direction-Rise of nationalism: Over the past decade and more, the world has been moving in the reverse direction. There has been an upsurge in narrow nationalism, an assertion of parochial interests over the pursuit of shared interests and a fostering of competition among states rather than embracing collaboration.
    • The global challenge of COVID-19: COVID-19 has brought these deepening contradictions into very sharp relief. This is a global challenge which recognises no political boundaries. It is intimately linked to the whole pattern of large-scale and high-density food production and distribution.
    • Health crisis turned into economic crisis: It is a health crisis but is also spawning an economic crisis through disrupting global value chains and creating a simultaneous demand shock. It is a classic cross-national and cross-domain challenge.

    How countries are dealing with COVID-19 and possible outcomes

    • No coordination at the international level: But interventions to deal with the COVID-19 crisis are so far almost entirely at the national level, relying on quarantine and social distancing. There is virtually no coordination at the international level.
    • Blame game at the international level: We are also seeing a blame game erupt between China and the United States which does not augur well for international cooperation and leadership.
    • The hopeful outcome of international cooperation: While this is the present state of play, the long-term impact could follow alternative pathways.
      • One, the more hopeful outcome would be for countries to finally realise that there is no option but to move away from nationalistic urges and embrace the logic of international cooperation through revived and strengthened multilateral institutions and processes.
    • The depressing outcome of intense nationalist trends: The other more depressing consequence may be that nationalist trends become more intense, countries begin to build walls around themselves and even existing multilateralism is further weakened.
      • Institutions such as the United Nations and the World Health Organization which are already marginalised may become increasingly irrelevant.
      • There could be a return to autarkic economic and trade policies and an even deeper and more pervasive anti-globalisation sentiment.
    • Depression decade ahead: Unless there is a conscious effort to stem this through a reaffirmation of multilateralism, we are looking at a very depressing decade ahead.
      • This is when the world needs leadership and statesmanship, both in short supply.
    • Contrast with the financial crisis: This is in contrast to the U.S.-led response to the global financial and economic crisis of 2008 when the G-20 summit was born and a coordinated response prevented catastrophic damage to the global economy.

    Leadership role for India

    • Is there a role here for India which is a key G-20 country, the world’s fifth-largest economy and with a long tradition of international activism and promotion of rule-based multilateralism?
    • In this context, Prime Minister Narendra Modi’s remarks at the recent Economic Times Global Business Summit are to be welcomed.
      • While speaking of the COVID-19 crisis, he said, “Like today, the world is facing a huge challenge in the form of Corona Virus. Financial institutions have also considered it a big challenge for the financial world. Today, we all have to face this challenge together. We have to be victorious with the power of our resolution of ‘Collaborate to Create’.”
      • He went on to observe that while the world today is “inter-connected, inter-related and also interdependent”, it has “not been able to come on a single platform or frame a Global Agenda, a global goal of how to overcome world poverty, how to end terrorism, how to handle Climate Change issues.”
    • From “Equal distance” to friendship with all: Modi lauded government’s policy of seeking friendship with all countries as contrasted from the earlier policy of non-alignment. He seemed to suggest that non-alignment was a defensive policy which advocated “equal distance from every country”.
      • Now, he claimed, India was still “neutral” — presumably meaning non-alignment — “but not on the basis of distance but on the basis of friendship”.
      • He cited India’s friendship with Iran and Saudi Arabia, and with the U.S. as well as Russia.

    India’s foreign policy

    • Non-alignment: Mr Modi may wish to distinguish his foreign policy from that of his predecessors, but what he describes as its “essence” is hardly distinguishable from the basic principles of Indian foreign policy since Nehru.
    • Non-alignment was not defensive: India’s non-alignment was anything but defensive. The international peace-keeping contribution that the Prime Minister referred to has its origins in Nehru’s sense of international responsibility.
    • Friendship with all: India has always professed its desire to have friendly relations with all countries but has been equally firm in safeguarding its interests when these are threatened.
    • Mutually beneficial partnership: India’s non-alignment did not prevent it from forging strong and mutually beneficial partnerships with major countries.
      • The India-Soviet partnership from 1960-1990 is an example just as the current strategic partnership with the U.S. is.
    • Foreign policy rooted in a civilisational sense: The foreign policy of his predecessors had been rooted in India’s civilisational sense, its evolving place in the international system and its own changing capabilities.
      • Their seminal contributions should be acknowledged and built upon rather than proclaim a significant departure.

    Move in line with traditional foreign policy

    • The Prime Minister’s plea for global collaboration to deal with a densely interconnected world is in line with India’s traditional foreign policy.
      • Move in keeping with traditional activism on a global scale: A leadership role in mobilising global collaboration, more specifically in fighting COVID-19 would be in keeping with India’s traditional activism on the international stage.
    • Commendable SAARC move: The Prime Minister has shown commendable initiative in convening leaders of the South Asian Association for Regional Cooperation nations for a regional collaborative effort on COVID-19.
      • International initiative: This should be followed by an international initiative, either through the G-20 or through the U.N.

    Way forward

    • Reformed and Strengthened U.N. should be India’s agenda: The Prime Minister made no reference to the role of the U.N., the premier multilateral institution, as a global platform for collaborative initiatives. There may have been irritation over remarks by the UN Secretary-General on India’s domestic affairs and the activism displayed by the UN Commissioner for Human Rights on the Citizenship (Amendment) Act controversy.
      • The U.N. Secretary General’s statement on India’s domestic affairs and activism by UN Secretary-General on India’s domestic affairs should not influence India’s long-standing commitment to the U.N. as the only truly inclusive global platform enjoying international legitimacy despite its failings.
      • If one has to look for a “single platform” where a Global Voice could be created, as the Prime Minister suggested, surely a reformed and strengthened U.N. should be on India’s agenda.
    • Opportunity for India in the pandemic: The COVID-19 pandemic presents India with an opportunity to revive multilateralism, become a strong and credible champion of internationalism and assume a leadership role in a world that is adrift. The inspiration for this should come from reaffirming the wellsprings of India’s foreign policy since its Independence rather than seeking to break free.

    PCR Test for Diagnosis of the COVID-19

     

    The diagnosis of COVID-19 can be done with the Polymerase Chain Reaction (PCR) Test which is explained as under:

    The PCR Test

    • It uses a technique that creates copies of a segment of DNA. ‘Polymerase’ refers to the enzymes that make the copies of DNA.
    • Kary Mullis, the American biochemist who invented the PCR technique, was awarded the Nobel Prize for Chemistry in 1993.
    • The ‘chain reaction’ is how the DNA fragments are copied, exponentially — one is copied into two, the two are copied into four, and so on.
    • However, SARS-COV-2 is a virus made of RNA, which needs to be converted into DNA. For this, the technique includes a process called reverse transcription.
    • A ‘reverse transcriptase’ enzyme converts the RNA into DNA. Copies of the DNA are then made and amplified.
    • A fluorescent DNA binding dye called the “probe” shows the presence of the virus. The test also distinguishes SARS-COV-2 from other viruses.

    Various Stages:

    1) Collection and transport

    • Testing centre takes swabs from nasal cavities and back of the throat (pharynx), and puts samples in a “virus transport medium”, which contains balanced salts and albumin to prevent the virus from disintegrating.
    • Sample is then transported in cold storage to the testing lab.

    2) Extraction of viral RNA

    • Coronaviruses have large single-stranded RNA genomes.
    • Testing lab extracts the RNA from the samples, using commercially available kits.

    3) Putting THE RNA in THE PCR mix

    • Extracted RNA is added to a polymerase chain reaction (PCR) mix.
    • This includes the ‘master mix’, which contains a ‘reverse transcriptase’ enzyme that converts the RNA into DNA.
    • Master Mix contains Taq polymerase, the enzyme that creates copies of the DNA, nucleotides, as well as other elements such as magnesium — an ion of which is needed to amplify the DNA.
    • The PCR mix also contains ‘reagents’ such as ‘primers’ and ‘probes’.
    • Primers are particular strands of DNA that are designed to bind with the DNA that is to be copied; probes are used to detect the specific sequence in the DNA sample.
    • Finally, the PCR mix consists of a “housekeeping” gene — a normal human gene (RNAse P) that is used to ensure that samples were properly collected, and RNA extracted.

    4) Amplification of the viral DNA

    • Sample, in its PCR mix, is put into tubes or plates, which are then put in a thermal cycler machine that is used to conduct the PCR process.
    • First, the RNA is converted into DNA. Then the process of copying the genes starts.
    • The thermal cycler heats and cools the mixture with the sample, alternating between three temperatures — for melting the DNA to separate the two strands.
    • The thermal cycler runs 30-40 such cycles in order to amplify the DNA to check for the virus.

    5) Testing against controls

    • Amplified DNA is tested against a positive control, which usually consists of genes of the virus cloned into plasmid, and a negative control, which is a ‘known’ sample that has tested negative for the virus earlier.
    • RNase P should show amplification, positive control should be positive, negative control should be negative, and then whatever result you get for the specimen, is the correct result.
    • In order for a test to be valid before the result is released, certain ‘validity criteria’ have to be met.
    • If the housekeeping gene (RNase P) is positive, positive control is positive, negative control is negative, and the sample does not show any PCR positive result, the sample is declared negative.
    • If the PCR result is positive, the patient has COVID-19.

    Dumping of Radioactive Nuclear Waste

    In a controversial move, Japan has decided to dump the radioactive heavy water from the Fukushima nuclear power plant into the Sea.  The dumping of nuclear waste is considered to be the easiest way to get rid of it.

    What is Heavy Water?

    • Heavy water (deuterium oxide) is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium rather than the common hydrogen that makes up most of the hydrogen in normal water.
    • Heavy water is used in certain types of nuclear reactors, where it acts as a neutron moderator to slow down neutrons.
    • Slowed neutrons are more likely to react with the fissile uranium-235 than with uranium-238 which captures neutrons without fissioning.

    Where is Fukushima waste?

    • It is currently being stored in large tanks, but those are expected to be full by 2022.
    • Almost 1.2 million liters of radioactive water from the Fukushima nuclear power plant is to be released into the ocean.
    • The contaminated water has since been used to cool the destroyed reactor blocks to prevent further nuclear meltdowns.

    Hazards of the nuclear contamination

    • Radioactive pollution in the ocean has been increasing globally — and not just since the disaster at Fukushima.
    • Radiation levels in the sea off Fukushima were millions of times higher than the government’s limit of 100 Becquerel.
    • A single Becquerel that gets into our body is enough to damage a cell that will eventually become a cancer cell.
    • Even the smallest possible dose, a photon passing through a cell nucleus, carries a cancer risk. Although this risk is extremely small, it is still a risk.

    Who else dumped radioactive water into oceans?

    The dumping of nuclear waste in drums was banned in 1993 by the London Convention on the Prevention of Marine Pollution. But discharging liquid contaminated with radiation into the ocean is still permitted internationally.

    • The lion’s share of dumped nuclear waste came from Britain and the Soviet Union, figures from the IAEA show.
    • By 1991, the US had dropped more than 90,000 barrels and at least 190,000 cubic meters of radioactive waste in the North Atlantic and Pacific.
    • To this day, around 90% of the radiation in the ocean comes from barrels discarded in the North Atlantic, most of which lie north of Russia or off the coast of Western Europe.
