  • What is UV-C technology?

    The Union Ministry for Science and Technology has informed that Ultraviolet-C or UV-C Disinfection Technology will soon be installed in Parliament for the mitigation of airborne transmission of SARS-COV-2.

    UV-C air duct disinfection system

    • The UV-C air duct disinfection system was developed by CSIR-CSIO (Central Scientific Instruments Organisation).
    • The system is designed to fit into any existing air-ducts and the virucidal dosages using UV-C intensity and residence time can be optimized according to the existing space.
    • The release adds that the virus is deactivated in any aerosol particles by the calibrated levels of UV-C light. It can be used in auditoriums, malls, educational Institutions, AC buses, and railways.

    What is Ultraviolet (UV)?

    • Ultraviolet (UV) is a type of light or radiation naturally emitted by the Sun. It covers a wavelength range of 100-400 nm. The human visible light ranges from 380–700 nm.
    • UV is divided into three bands: UV-C (100-280 nm), UV-B (280-315 nm) and UV-A (315-400 nm).
    • UV-A and UV-B rays from the Sun are transmitted through our atmosphere and all UV-C is filtered by the ozone layer.
    • UV-B rays can only reach the outer layer of our skin or epidermis and can cause sunburns and are also associated with skin cancer.
    • UV-A rays can penetrate the middle layer of your skin or the dermis and can cause ageing of skin cells and indirect damage to cells’ DNA.
    • UV-C radiation from man-made sources has been known to cause skin burns and eye injuries.

    So, can UV-C kill coronavirus?

    • UV-C radiation (wavelength around 254 nm) has been used for decades to disinfect the air in hospitals, laboratories, and also in water treatment.
    • But these conventional germicidal treatments are done in unoccupied rooms as they can cause health problems.
    • It can destroy the outer protein coating of the SARS-Coronavirus.

    Is it safe for humans?

    • The device is specifically developed to disinfect non-living things.
    • UV-C radiation used in this device could be harmful to the skin and eyes of living beings.

  • What is lightning, and how does it strike?

    With the monsoon making a slow revival over several parts of India, except the northwest region, there is a rise in lightning-linked deaths.

    What is lightning?

    • Lightning is a very rapid — and massive — discharge of electricity in the atmosphere, some of which is directed towards the Earth’s surface.
    • These discharges are generated in giant moisture-bearing clouds that are 10-12 km tall.
    • The base of these clouds typically lies within 1-2 km of the Earth’s surface, while their top is 12-13 km away.
    • Temperatures towards the top of these clouds are in the range of minus 35 to minus 45 degrees Celsius.

    How does it strike?

    • As water vapour moves upward in the cloud, the falling temperature causes it to condense.
    • Heat is generated in the process, which pushes the molecules of water further up.
    • As they move to temperatures below zero degrees Celsius, the water droplets change into small ice crystals. They continue to move up, gathering mass — until they are so heavy that they start to fall to Earth.
    • This leads to a system in which, simultaneously, smaller ice crystals are moving up and bigger crystals are coming down.
    • Collisions follow and trigger the release of electrons — a process that is very similar to the generation of sparks of electricity.
    • As the moving free electrons cause more collisions and more electrons, a chain reaction ensues.
    • This process results in a situation in which the top layer of the cloud gets positively charged, while the middle layer is negatively charged.

    Making of the thunder

    • The electrical potential difference between the two layers is huge — of the order of a billion to 10 billion volts.
    • In very little time, a massive current, of the order of 100,000 to a million amperes, starts to flow between the layers.
    • An enormous amount of heat is produced, and this leads to the heating of the air column between the two layers of the cloud.
    • This heat gives the air column a reddish appearance during lightning. As the heated air column expands, it produces shock waves that result in thunder.

    How does this current reach the Earth from the cloud?

    • While the Earth is a good conductor of electricity, it is electrically neutral.
    • However, in comparison to the middle layer of the cloud, it becomes positively charged.
    • As a result, about 15%-20% of the current gets directed towards the Earth as well.
    • It is this flow of current that results in damage to life and property on Earth.
    • There is a greater probability of lightning striking tall objects such as trees, towers or buildings.
    • Once it is about 80-100 m from the surface, lightning tends to change course towards these taller objects.
    • This happens because air is a poor conductor of electricity, and electrons that are travelling through air seek both a better conductor and the shortest route to the relatively positively charged Earth’s surface.

    What precautions should be taken against lightning?

    • Lightning rarely hits people directly — but such strikes are almost always fatal.
    • People are most commonly struck by what are called “ground currents”.
    • The electrical energy, after hitting a large object (such as a tree) on Earth, spreads laterally on the ground for some distance, and people in this area receive electrical shocks.
    • It becomes more dangerous if the ground is wet (which it frequently is because of the accompanying rain), or if there is metal or other conducting material on it.
    • Water is a conductor, and many people are struck by lightning while standing in flooded paddy fields.
    • For the reasons given above, taking shelter under a tree is dangerous. Lying flat on the ground too can increase risks.
    • People should move indoors in a storm; however, even indoors, they should avoid touching electrical fittings, wires, metal, and water.

    Answer this PYQ in the comment box:

    Q.During a thunderstorm, the thunder in the skies is produced by the:

    (a) 1 only

    (b) 2 and 3 only

    (c) 1 and 3 only

    (d) None of the above

  • Case for an anti-discrimination law

    Context

    “Silent segregation” on the grounds of marital status, gender, sexual orientation or eating preferences are followed in several housing societies and residents’ associations. Legal remedies are needed for its victims.

    Issue of the prevalence of discrimination on various grounds

    • The recent Pew Research Center Report has confirmed that a substantial number of Indians prefer not to have a person from a different religious community as their neighbour.
    • The absence of a proper legal recourse for those who suffer from housing discrimination only makes matters worse.
    • Social prejudice against members of the LGBTQIA+ community in the country remains strong, despite Section 377 of the Indian Penal Code was read down by the Supreme Court of India.
    • In April, the Supreme Court, in Patan Jamal Vali vs State of Andhra Pradesh, recognised intersectional discrimination.
    • It is discrimination on the basis of the intersection of personal characteristics, such as that faced by Dalit women as Dalits, as women and in the unique category of Dalit women.
    • Discriminatory practices may also be indirect in nature, whereby policies that seem neutral and not expressly targeted at a particular group, still cause a disproportional adverse impact on disadvantaged sections of society.

    Why Article 15(1) is not enough

    • Article 15(1) of the Constitution of India prohibits the state from discriminating against individuals on basis of certain protected characteristics such as religion, race, caste, sex and place of birth.
    • But it does not bar private individuals or institutions from doing what the state is not permitted to.
    • Nor does it expressly list ethnicity, linguistic identity, nationality, marital status, sexual orientation, disability, physical appearance and other personal characteristics as prohibited grounds of discrimination.

    We need a comprehensive anti-discrimination legal framework

    • A comprehensive anti-discrimination legal framework is required to fill the existing legal lacunae.
    • India is one of the few liberal democracies without such a framework.
    • The Sachar Committee, in 2006, recognised the need for an anti-discrimination law.
    • This was further reiterated by the Expert Group on Equal Opportunity Commission headed by Prof. N.R. Madhava Menon.

    Way forward

    • The States can lead the way, by enacting anti-discrimination laws in their respective jurisdictions.
    • States have a vital role in strengthening our right to equality.
    • The State legislature can use its powers under Entry 8 of List III in the Seventh Schedule to the Constitution to enact an anti-discrimination law.
    • And if States take the initiative, the demand for a national anti-discrimination law to cover services and institutions under the domain of the Union government will be reignited.
    • The law should have provisions that prohibit employers, landlords, traders, service providers, private persons performing public functions, and public authorities, from discriminating.
    • Law should prohibit discrimination on grounds of caste, race, ethnicity, descent, sex, gender identity, gender expression, pregnancy, sexual orientation, religious identity, tribe, disability, linguistic identity, HIV-status, nationality, marital status, dietary preference, skin tone, physical appearance, place of residence, place of birth, age or analogous characteristics which are beyond the control of an individual or those that constitute a fundamental choice.
    • The law should also balance the anti-discrimination mandate with other rights guaranteed by the Constitution.
    • The anti-discrimination mandate can be restricted in pursuance of a legitimate objective.
    • Affirmative-action provisions can be included whereby public authorities are obliged to progressively realise diversification of their workforces.

    Consider the question “Article 15(1) of the Constitution of India prohibits the state from discriminating against individuals on basis of certain protected characteristics. But it does not bar private individuals or institutions from doing what the state is not permitted to. In light of this, discuss the need for anti-discrimination law in India and its provisions.”

    Conclusion

    We must recognise that anti-discrimination law is not a panacea for the problems of inequality and social prejudice that are deeply rooted in our society. Nevertheless, it is a necessary step — an idea whose time has come.

  • Arbitration in India: Issues

    Context

    Plagued by delays and rising costs, arbitration in India needs urgent attention. The pandemic has only worsened the situation.

    Issues with arbitrations process in India

    • Arbitrations in India suffers from rising costs and sluggish proceedings.
    • Arbitration proceedings are often dragged on by lawyers on either side filing misconceived applications at various stages of the proceedings.
    • Litigants, too, at times contribute to this delay with their stubbornness in not conceding a loss or defeat.
    • The courts have narrowed down the scope of judicial interference under Section 34 of the Arbitration and Conciliation Act.
    • The very limited recourse for setting aside an arbitral award under the Act invariably means that it will be upheld, even if it appears unfair or illogical.
    • The aggrieved party may well be stuck with the award and precluded forever from challenging it.
    • Arbitration hearings are generally held in camera, and decisions are usually not publicly accessible, giving rise to doubts about impartiality and fairness.
    • Arbitration proceedings have become more complex with time.
    • The Supreme Court, in Guru Nanak Foundation v. Rattan Singh and Sons, had expressed disappointment against the procedural delays and tardiness in the resolution of disputes through arbitration.
    • Even the clauses providing for fees of the arbitrators and fixed timelines for disposal are often disregarded by the players
    • The inevitable consequence of these drawbacks is a slow departure of the biggest litigant, the government, from the arbitration spectrum.
    • A sector that is dominated by approvals, protocols and scrutiny, uncertainty about the budget outlay towards arbitrations and unexpected delays in disposal does not inspire confidence and detracts from the sanctity of the process.

    Way forward

    • Arbitrators have endeavoured to simplify the proceedings by limiting the pleadings, insisting on written arguments, reducing the number of sittings and laying down a schedule for various milestones.
    • Some restraint is needed from all quarters to bring its wheels back on the tracks. These are:
    • A small check on the arbitral fees and timelines.
    • Careful drafting of arbitration clauses.
    • Stringent procedural safeguards to curb delays.
    • Expeditious disposal of the court proceedings and legislative intent towards all of the above.

    Consider the question “What are the issues faced by the arbitration in India? Suggest the measures to deal with these issues.” 

    Conclusion

    Arbitration still has the inherent potential and characteristics to outperform other modes of dispute resolution, but for that to happen, some changes are a must.

  • New Ministry of Cooperation should enable people to leverage community networks

    Context

    India now has a Ministry of Cooperation that aims to strengthen the country’s cooperative movement. This is an opportune moment to look at the movement’s history, examine the potential of cooperatives and analyse the challenges they face.

    Development of Farmer Producer Companies in India

    • India’s significant tryst with dairy cooperatives began in the 1950s with the success of what we know today as Amul.
    • The nation took note of this initiative and the National Dairy Development Board was set up in 1965.
    • However, the expansion wasn’t working the way it had been envisaged.
    • The need for a new model was felt soon as cooperatives outside Anand were not holding regular and proper elections.
    • Their accounts were not audited.
    • As a result, a committee was set up in the Company Affairs Ministry to allow farmers to set up companies.
    • The Farmer Producer Companies (FPCs) would run on the principle of “one share one vote” and the essence of cooperatives would not be diluted.
    • The Parliamentary Committee looked into the Bill to give legal backing to FPCs, with this, the Companies Act (Second Amendment), 2002 became law.

    Funding the FPCs

    • The existing funding vehicles were designed to cater to cooperatives, not FPCs
    •  Around 2010, the Boston Consulting Group (BCG) had been commissioned to develop a plan for restructuring NABARD.
    • As a result, the restructured NABARD had a special window for FPCs.

    Community-based cooperatives

    •  The Cheliya community set up a chain of Hearty Mart “cooperative” supermarkets in villages in Gujrat using the franchise model.
    •  Just as the network of Charotar Patels that Kurien relied on in the case of Amul —Cheliya community have played a key role in the spread of the model.
    • The idea of leveraging the community network was tried in some parts of the country in the context of re-imagining economic infrastructure.
    • To deal with the electricity board failures, a distribution company was run on a community basis.
    • This model has, in fact, worked in places like Kanpur, even Kerala.

    Social cooperatives

    • The concept of social cooperatives builds on the idea of communities creating infrastructure by using local material and family labour.
    • These can be the village tank, paving the village road — with or without MGNREGA — finishing the last-mile construction of a canal network or even keeping watch on the contractor.
    • The pandemic seems to have increased the significance of community effort.
    • Reducing vaccine hesitancy, providing food to those waiting outside hospitals and, most importantly, looking after orphaned children are imperatives crying out for the cooperative model.

    Way forward for new Ministry of Cooperatives

    •  Keeping in mind social needs while using resources is a large part of the solution to our current predicament.
    • The pandemic will not follow the laws of corporate finance, cooperation has a lot to speak for itself, the new ministry should take this message.
    • The new work-from-home model will create several problems as well as offer opportunities.
    • The new ministry is a recognition of the needs of our times.
    • But it should not be just about pumping in money. 

    Conclusion

    This is the time to design models that help those who help themselves. We will wait expectantly to see how the new ministry works.

  • Uttar Pradesh Population Policy 2021-2030

    On World Population Day, Uttar Pradesh CM has released the state’s new population policy, which aims to reduce its growth rate to 2.1 per cent over the next 10 years.

    Why UP needs such policy?

    • Uttar Pradesh, India’s most populous state, has a population of around 220 million.
    • In Uttar Pradesh, there are limited ecological and economic resources at hand.
    • It was necessary that the provision of basic necessities of human life, economic/livelihood opportunities and a secure living is accessible to all citizens.

    Provisions of UP Population Policy

    The provision of this legislation shall apply to a married couple where the boy is not less than 21 years of age and the girl is not less than 18.

    [A] Contraception and Abortion

    • The state population policy will focus on efforts to increase the accessibility of contraceptive measures issued under the Family Planning Programme.
    • It would provide a proper system for safe abortion
    • Focus area to include reducing the newborns and maternal mortality rate.
    • Care of the elderly, and better management of education, health, and nutrition of adolescents between 11 to 19 years has also been ensured in the policy, according to the state government

    [B] Two-child policy

    Perks

    • The state government will give promotions, increments, concessions in housing schemes and others perks to employees who adhere to population control norms, and have two or less children
    • “Public servants who adopt the two-child norm will get two additional increments during the entire service, maternity or as the case may be.

    Paternity leaves

    •  There shall be paternity leave of 12 months, with full salary and allowances and three percent increase in the employer’s contribution fund under the National Pension Scheme.
    • Those who aren’t government employees and still adhere to two-child policy will get benefits in rebates in taxes on water, housing, home loans etc.
    • It also states that maternity centres will be set up at all primary health centres.

    Incentives for sterilization

    • As per the draft, several incentives have been provided to people, including public servants, if they adopt the norm by undergoing voluntary sterilization.
    • The incentives include a 3% increase in the employer’s contribution fund under national pension; two additional increments during the entire service; subsidy towards purchase of plot or house site or build house etc.
    • A couple living below the poverty line who have only one child and undergoes voluntary sterilisation, shall be eligible for payment of a one-time ₹80,000 if the single child is a boy and ₹1 lakh if it is a girl.

    Who will not benefit from the law?

    • According to the bill, people having more than two children in UP will be debarred from benefits of all government-sponsored welfare schemes, cannot contest local polls.
    • They shall be ineligible to apply for government jobs under the state or receiving any kind of subsidy, cannot get a promotion in a government job and his or her ration card would be limited to four members.

    How will the state implement measures?

    • The UP government plans to set up a state population fund to implement the measures.
    • The draft bill also asks the state government to introduce population control as a compulsory subject in all secondary schools.

    Back2Basics: Fertility Rate

    • Fertility rate may be defined as the number of children that would be born of a woman during her reproductive years.
    • For a country’s population to remain stable, it is the total fertility rate should be 2.1.
    • Studies suggest that India’s national fertility rate is 2.2 at the moment.

  • How China eliminated malaria and the road ahead for India

    Recently, El Salvador and China were declared malaria-free by the WHO.

    What is Malaria?

    • Malaria is a disease caused by a parasite called plasmodium vivax, p. filarium.
    • The parasite is spread to humans through the bites of infected mosquitoes.
    • People who have malaria usually feel very sick with a high fever and shaking chills.
    • While the disease is uncommon in temperate climates, malaria is still common in tropical and subtropical countries.

    How many countries have successfully eliminated malaria?

    • Since 1900, 127 countries have registered malaria elimination. This is definitely not an easy task.
    • It needs proper planning and a strategic action plan based on the local situations.
    • All these countries followed the existing tools and strategies to achieve the malaria elimination goal.
    • The main focus was on surveillance.
    How did China eliminate malaria?
    • China followed some specific strategies, namely strong surveillance following the ‘1-3-7’system: malaria diagnosis within 1 day, 3 days for case investigation and by day 7 for public health responses.
    • Molecular Malaria Surveillance for drug resistance and genome-based approaches to distinguish between indigenous and imported cases was conducted.
    • All borders to the neighboring countries were thoroughly screened to prevent the entry of unwanted malaria into the country.

    What is the current scenario of malaria in India?

    • As per the Global Malaria Report 2020 by the World Health Organization (WHO) India shared 2% of the total global malaria cases in 2019.
    • India has a great history of malaria control.
    • The highest incidence of malaria occurred in the 1950s, with an estimated 75 million cases with 0.8 million deaths per year.
    • The launch of National Malaria Control Programme in 1953 and the National Malaria Eradication Programme in 1958 made it possible to bring down malaria cases to 100,000 with no reported deaths by 1961.
    • This is a great achievement been made so far.

    Unexpected resurgence

    • But from a nearing stage of elimination, malaria resurged to approximately 6.4 million cases in 1976.
    • Since then, confirmed cases have decreased to 1.6 million cases, approximately 1100 deaths in 2009 to less than 0.4 million cases and below 80 deaths in 2019.
    • India accounted for 88% of malaria cases and 86% of all malaria deaths in the WHO South-East Asia Region in 2019.
    • It is the only country outside Africa among the world’s 11 `high burden to high impact’ countries.

    Road ahead for India

    Collaboration:

    • India is a signatory to National Framework for Malaria Elimination (NFME) 2016-2030 aiming for malaria elimination by 2030.
    • This framework has been outlined with a vision to eliminate the disease from the country which would contribute to improved health with quality of life and poverty alleviation.
    • China collaborated with Harvard University and the Massachusetts Institute of Technology, USA for Molecular Malaria Surveillance.
    • In India, there are very dedicated expert scientists who can take up such assignments.

    Diagnosis:

    • India stands at a very crucial stage. The present challenge is the detection of asymptomatic cases in most endemic areas.
    • Molecular Malaria Surveillance must be used to find out the drug-resistant variants and genetic-relatedness studies to find out the imported or indigenous cases.
    • The surveillance must be strengthened and using smart digital surveillance devices would be an important step. Real-time and organic surveillance is needed even in remote areas.

    Monitoring:

    • The results of each malaria case can be registered in a central dashboard at the National Vector Borne Disease Control Programme, as it is done for COVID-19 cases by Indian Council of Medical Research.
    • All intervention activities must strictly be monitored.
    • Vector biology, site of an actual vector mosquito bite, host shifting behaviour, feeding time, feeding behaviour and insecticide resistance studies need to be carried out to support the elimination efforts.

  • EAM hands over relics of 17th century Georgian Queen St. Ketevan to Georgia

    After a long-standing request of Georgia, External Affairs Minister handed over the holy relics of 17th century Georgian Queen St. Ketevan nearly 16 years after they were found in Goa.

    Who was St. Ketevan?

    • Queen Ketevan was a 17th century Georgian Queen.
    • From Kakheti, a kingdom in eastern Georgia, she was tortured and killed in 1624 in Shiraz during the rule of the Safavid dynasty.
    • Portuguese missionaries were said to have carried the relics to Goa in 1627.
    • In 2005, after years of research and study of medieval Portuguese records, the relics were found at the St. Augustine Church in Old Goa.

    Importance of Georgia for India

    • Georgia a strategically important country situated at the intersection of Eastern Europe and Western Asia.
    • Relations between Georgia and India date back to ancient times.
    • The Panchatantra influenced Georgian folk legends. During the medieval period, Georgian missionaries, travelers, and traders visited India.
    • Some Georgians served in the courts of Mughal emperors, and a few rose to the rank of governor.
    • India was among the first countries to officially recognize Georgia, doing so on 26 December 1991.
    • India is a net exporter to Georgia.
    • The main commodities exported by India to Georgia are cereals, nuclear reactors, boilers, machinery and mechanical appliances, pharmaceuticals, electrical machinery and equipment, aluminium and aluminium articles.

  • 2020 Millennium Technology Prize  

    The 2020 Millennium Technology Prize has been awarded to Shankar Balasubramanian and David Klenerman, for their development of revolutionary Next-generation DNA sequencing techniques.

    About Millennium Technology Prize

    • The Millennium Technology Prize is one of the world’s largest technology prizes.
    • It is awarded once every two years by Technology Academy Finland, an independent fund established by Finnish industry and the Finnish state in partnership.

    What is next-generation DNA sequencing?

    • Next-generation sequencing (NGS) is a massively parallel sequencing technology that offers ultra-high throughput, scalability, and speed.
    • The technology is used to determine the order of nucleotides in entire genomes or targeted regions of DNA or RNA.
    • These technologies allow for sequencing of DNA and RNA much more quickly and cheaply than the previously used sequencing.
    • NGS has revolutionized the biological sciences, allowing labs to perform a wide variety of applications and study biological systems at a level never before possible.
    • More than a million base pairs can be sequenced, which translates to hundreds of genes or even the whole genome of an organism.
    • This is made possible by simultaneously sequencing hundreds of pieces of DNA at the same time.

    What is sequencing, btw?

    • DNA (or RNA, in some viruses), the genetic material of life forms, is made of four bases (A, T, G and C; with U replacing T in the case of RNA).
    • A chromosome is the duplex of a long linear chain of these – and in the DNA sequence is information – the blueprint of life.
    • Life famously can replicate, and DNA replicates when an enzyme, DNA polymerase, synthesises a complementary strand using an existing DNA strand as the template.
    • The breakthrough idea of Balasubramanian and Klenerman was to sequence DNA (or RNA) using this process of strand synthesis.
    • They cleverly modified their ATGC bases so that each shone with a different colour.
    • When copied, the “coloured” copy of DNA could be deciphered from the colours alone, using miniature optical and electronic devices.

    What about the cost of all this sequencing?

    • When the Human Genome Project delivered the first, near-complete sequence of our genome, the cost was estimated to have been 3 billion dollars.
    • As all our chromosomes together have 3 billion base pairs, it becomes an easy calculation – One dollar per sequenced base.
    • By the year 2020, NGS technologies has pushed the price for sequencing to a few thousands of rupees.

  • Places in news: Kesaria Buddhist Stupa

    The world-famous Kesaria Buddha stupa in east Champaran district of Bihar is waterlogged following floods in some parts of the district after heavy rainfall in the catchment areas of river Gandak in neighbouring Nepal.

    Kesaria Stupa

    • The Kesaria stupa, located about 110 km from the State capital Patna, has a circumference of almost 400 feet and stands at a height of about 104 feet.
    • The first construction of the nationally protected stupa is dated to the 3rd century BCE.
    • It is regarded as the largest Buddhist stupa in the world and has been drawing tourists from across several Buddhist countries.
    • The sputa’s exploration had started in the early 19th century after its discovery led by Colonel Mackenzie in 1814.
    • Later, it was excavated by General Cunningham in 1861-62 and in 1998 an ASI team led by archaeologist K.K. Muhammad had excavated the site properly.
    • The original Kesaria stupa is said to date back to the time of emperor Ashoka (circa 250 BCE) as the remains of an Ashokan pillar was discovered there.

    In the accounts of foreign travellers

    • The stupa mound may even have been inaugurated during the Buddha’s time, as it corresponds in many respects to the description of the stupa erected by the Licchavis of Vaishali to house the alms bowl the Buddha has given them.
    • Interestingly, Chinese travellers Fa-Hien (5th century CE) and Hiuen Tsang (7th century CE), who travelled to India, also mention this stupa and the legend of Buddha and the Licchavis, in their records.
    • While Fa-Hien talks of a pillar erected at the site, Hiuen Tsang mentions the stupa itself.
