  • [pib] National Migrant Information System (NMIS)

    The National Disaster Management Authority (NDMA) has developed an online Dashboard – National Migrant Information System (NMIS).

    Did you notice, the peculiarity of the NMIS? The portal is developed and maintained by the National Disaster Management Authority (NDMA) not Ministry of Labour & employment or Labour bureau.

    About NMIS

    • The NMIS aims to capture the information regarding the movement of migrants and facilitate the smooth movement of stranded persons across States.
    • The key data pertaining to the persons migrating has been standardized for uploading such as name, age, mobile no., originating and destination district, date of travel etc., which States are already collecting.
    • States will be able to visualize how many people are going out from where and how many are reaching destination States.
    • The mobile numbers of people can be used for contact tracing and movement monitoring during COVID-19.

    Benefits

    • The portal helps maintain a central repository on migrant workers and help in speedy inter-State communication/co-ordination to facilitate their smooth movement to native places.
    • It has additional advantages like contact tracing, which may be useful in overall COVID-19 response work.

  • [pib] Iron-Manganese based Biodegradable Alloy

    Indian scientists have jointly developed new generation Iron-Manganese based alloys for biodegradable metal implants for use in humans.

    Do you remember the Johnson and Johnson’s faulty hip implants case?? The alloy mentioned in the newscard can prove to be a gamechanger in the field of medical implants.

    Iron-Manganese based Biodegradable Alloy

    • Biodegradable materials (Fe, Mg, Zn, and polymer) can participate in the healing process and then degrade gradually by maintaining mechanical integrity without leaving any implant residues in the human body.
    • They are better alternatives to currently used metallic implants which remain permanently in the human body and can cause long-term side effects like systemic toxicity, chronic inflammation, and thrombosis.
    • The ARCI team employed both conventional melting and powder metallurgy techniques in the manufacturing of the new Fe-Mn based biodegradable alloys.
    • The alloy Fe-Mn (having Mn composition of more than 29% by weight) is a promising biodegradable metallic implant which exhibits a single austenitic phase (a non-magnetic form of iron) with MRI compatibility.

    Easy degradation

    • The alloy also showed a degradation rate in the range of 0.14-0.026 mm per year in the simulated body fluid.
    • It means that the Fe-Mn alloy exhibits mechanical integrity for 3-6 months and completely, disappears from the body in 12-24 months.
    • During the degradation process, calcium phosphate deposits on the implant due to local alkalization and saturation of calcium and phosphate, allow cells to adhere onto the surface to form tissues.

    Benefits

    • The Fe-Mn alloy produced at ARCI exhibited 99% density with impressive mechanical properties and behaved as a nonmagnetic material even under a strong magnetic field.
    • These properties are comparable to presently used permanent Titanium (Ti) and stainless-steel metallic implants (which is very costly).

  • International Day of Light and its significance

    The UN marks the International Day of Light (IDL) — an annual initiative held globally to raise awareness on the critical role played by light-based technologies in everyday life.

    The IDL as mentioned in the news creates no scope for a possible prelim question, but the purpose behind its celebration does.  i.e. LASER technology. LIDAR is the latest development in the LASER technology. UPSC may puzzle you here by asking the working principle of LIDAR.

    International Day of Light (IDL)

    • The IDL is administered from the International Basic Science Programme (IBSP) of UNESCO, and its Secretariat is located at the Abdus Salam International Centre of Theoretical Physics (ICTP) at Trieste, Italy.
    • The IDL highlights the contribution of such technologies in various avenues such as science, technology, art, and culture, thus helping achieve the UNESCO goals of education, equality, and peace.
    • The day selected, May 16, marks the anniversary of the first successful operation of the LASER in 1960 by physicist and engineer Theodore Maiman.
    • The LASER is a perfect example of how a scientific discovery can yield revolutionary benefits to society in communications, healthcare and many other fields.

    Why is the IDL celebrated?

    • In 2015, to raise global awareness of the achievements of light science and its applications, the UN observed the International Year of Light and Light-based Technologies 2015 (IYL 2015).
    • The event helped establish links and collaborations between decision-makers, industry leaders, scientists, artists, social businesses, NGOs, and the public at large.
    • Following the success of IYL 2015, Ghana, Mexico, New Zealand and Russia placed a resolution before the UNESCO Executive Board supporting the idea of an International Day of Light.
    • It was adopted on September 19, 2016, at the Board’s 200th session at the UNESCO HQ in Paris, France.
    • The Board decision was endorsed by the UNESCO General Conference at its 39th session on November 7, 2017, and the first IDL was held on May 16, 2018.

    Back2Basics: LASER

    • A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
    • It is an acronym for “light amplification by the stimulated emission of radiation.
    • The laser stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation.
    • The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths.
    • Many different types of lasers have been developed, with highly varied characteristics.
    • A laser is widely used in industrial cutting, surgical removal of tissues etc.
    • LIDAR is the most famous application of LASERs.

    LiDAR (Light Detection And Ranging)

    • It is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth.
    • It bounces pulsed laser light off the ground, revealing contours hidden by dense foliage.
    • These light pulses—combined with other data recorded by the airborne system— generate precise, three-dimensional information about the shape of the Earth and its surface characteristics.
    • LIDAR systems allow scientists and mapping professionals to examine both natural and manmade environments with accuracy, precision, and flexibility.
    • A LIDAR instrument principally consists of a laser, a scanner, and a specialized GPS receiver.
    • Airplanes and helicopters are the most commonly used platforms for acquiring LIDAR data over broad areas.

  • Mapping: Baltic Travel Bubble

    The Baltic countries of Estonia, Latvia and Lithuania have opened their borders to one another, creating a coronavirus “travel bubble” with an improvised idea to boost travel into their countries.

    Mark the following things on Map:

    1. Baltic Sea and its bordering nations

    2. Irben Strait

    3. Gulf of Riga

    4. Gulf of Finland

    Baltic Travel Bubble

    • The ‘Baltic travel bubble’ aims to facilitate the citizens of these three countries to travel within the region without hassles.
    • However, those who are coming from any other than these three countries would be required to follow self-isolation guidelines and stay in quarantine for exactly 14 days.
    • During the epidemic, Estonia and Lithuania closed their borders to non-citizens and all three nations placed mandatory quarantines for those entering for reasons related to non-work activities.
    • The region has been part of the European Union since 2004 and since 2007 has been a member of the European Schengen Free Travel Area.

    Significance of the travel ease

    • The Baltic nations have shown trust in each other’s healthcare system and have concluded that they have been able to tackle the coronavirus outbreak efficiently.
    • For Asian countries including India, these developments can provide interesting pointers when lockdown relaxations pertaining to travel and flights are being considered.

    Bonus: Try this question from CSP 2011

    Between India and East Asia, the navigation-time and distance can be greatly reduced by which of the following?

    1. Deepening the Malacca straits between Malaysia and Indonesia.

    2. Opening a new canal across the Kra isthmus between the Gulf of Siam and Andaman Sea.

    Which of the statements given above is/are correct?

    (a) 1 only

    (b) 2 only

    (c) Both 1 and 2

    (d) Neither 1 nor 2

  • Species in news: Troglomyces twitteri

    A new species has just been identified on an old image on Twitter. It is named as Troglomyces twitteri.

    The species Troglomyces twitteri has something unique in its name. UPSC may ask a straight forward question like – The specie Troglomyces twitteri recently seen in news is a- (a) Algae (b) Fungi (c) Fish (d) Sea Grass …….

    Troglomyces twitteri

    • Troglomyces twitteri is a type of parasitic fungus.
    • It belongs to an order called Laboulbeniales — tiny fungal parasites that attack insects and millipedes.
    • These fungi live on the outside of host organisms; in this case, on the reproductive organs of millipedes.
    • Laboulbeniales were first discovered in the middle of the 19th century.

  • War and Peace: Analysis of BSF’s role

    The BSF came into being in the wake of the 1965 India-Pakistan war. So, its ‘innate’ tasks involves both wartime and peacetime roles. This article is written by a retired IPS officer who has been ADG of BSF.  Our aim is to provide you with on-ground experience of issues in this security force. Focus of the article is on the preparedness of the BSF for its wartime role. From the exam perspective, focus on issues and possible solutions.

    Role of BSF

    • Officially, its role is defined in expansive terms like ‘security of the border of India and matters connected therewith’.
    • The tasks of BSF are divided into peacetime and wartime.
    • 1) The peacetime tasks include preventing smuggling and any other illegal activity, and unauthorised entry into or exit from the territory of India, etc.
    • 2) The wartime tasks of the BSF include holding ground in less threatened sectors, etc.

    Unpreparedness in wartime role

    • The BSF, in terms of its defences, equipment, weaponry and training, is not at all prepared for its wartime role.
    • This means that in the eventuality of any military assault, our ‘first line of defence’ would simply crumble.
    • Falling back on army’s mobilizations for a counterattack may take up to several days.
    • Retreat and loss of territory in this period is a possible scenario.
    • The report titled ‘Border Security: Capacity Building and Institutions’ of the department-related Parliamentary Standing Committee on Home Affairs, submitted to the Rajya Sabha on April 11, 2017:
    • Does not talk about the wartime role of the BSF even once.
    • It talks only of its peacetime role including fencing, floodlights and roads along the borders, development of integrated check posts, and construction of strategic roads.

    The fallacy of infantry attack

    • The founders of the BSF, including the committee of secretaries, had a wrong presumption that the assault on the ‘first line of defence’ will be by the enemy’s ‘exposed’ infantry.
    • This assault, they imagined, would be repulsed by BSF soldiers wielding similar arms.
    • But that presumption is a folly.
    •  Now, as a rule of thumb, infantry assault, whether supported by armour or not, or even a purely armour assault on any position is preceded by as heavy and as accurate artillery bombardment as possible.
    • If the attacking nation could afford it, such as the US during the 1991 Gulf War the bombardment could be aerial also.

    Unprepared to withstand shelling

    • Our ‘first line of defence’ does not have any defensive structures or fortifications that could withstand artillery bombardment even for a minute.
    • According to photographs available in the public domain, most BSF observation posts on the international border are ramshackle structures of tin sheets and sandbags erected on small mounds of earth.
    • Adding to that, the mounds are in full view of the enemy and their locations are known to them to the last centimetre.

     Uninspiring weaponry

    • The photographs of the 105 mm Indian Field Gun and their staple, the 7.62 mm medium machine gun are available in public domain.
    • The 105 mm Indian Field Guns have been placed under the operational command of the army, and BSF would not be able to use them when the enemy makes first contact with them.
    • That leaves them with their 51 mm and 81 mm mortars.
    • The 51mm mortar, with just 109 grams of explosive per shell and a maximum range of  850 m is as good as useless in a war.
    • The 81 mm mortar bomb with an explosive charge of 750 grams has a maximum range of 6000 m.
    • The enemy artillery would in any case be firing from way beyond that range, thereby making effective retaliation through mortars impossible.
    • Even when enemy IFV/APC or armour would come closer and in range, the smooth-bore 81 mm mortar is inherently not accurate enough to hit a moving vehicle. (smoothness of bore reduces accuracy)
    • Even the NATO rifled 120 mm mortars have a CEP (circular error probable) of 136 m.
    • As for the 7.62 mm medium machinegun, it is an anti-personnel weapon with the armour penetration of the M80 bullet being just 3 mm at 500m.
    • That makes it useless against even lightly armoured vehicles.
    • This means that the BSF outposts will not be able to deliver any effective fire at all on an enemy assault.

    IPS leadership issue

    • Since the BSF’s inception, the force’s Indian Police Service (IPS) leadership has not focused on the wartime role of the BSF.
    • The IPS officers in top positions in the BSF lack knowledge of military science that could enable them to appreciate and address the wartime role.

    Way forward

    •  The only defence feasible against artillery bombardment is to go sub-surface—in the form of deep concrete dugouts and fire trenches.
    • Then we also need elaborate anti-tank ditches.
    • To deliver effective fire on enemy armoured and lightly armoured vehicles, and infantry operating under their protection, the BSF needs weapons which carry enough explosive payloads to tackle armour, both light and heavy.
    • Portability, manoeuvrability and accuracy are important considerations in the ‘first line of defence’ attacking armour.
    • A veritable battery of ATGMs and cheaper yet accurate options like the 80 mm Breda Folgore RCL are available.
    • Using them effectively would require defensive fighting positions interconnected by communication trenches.
    • Research needs to be done to mount weapons like the Shipunov 2A42 30 mm autocannon on platforms faster than the BMP-2.
    • Similarly, MMGs/GPMGs need mobile platforms like Humvees to increase their survivability as well as effectivity.

    Consider the question “The BSF, which is often hailed as India’s ‘first line of defence’ has tasked with wartime and peacetime roles. Though it is quite adept in peacetime role, its wartime preparedness needs an overhaul. Comment.”

    Conclusion

    These issues with the BSF could result in a  situation where there is every possibility of rout and retreat in the early days of the war. This issue needs to be urgently addressed by the government.

  • Tale of two crises: Global Financial Crisis (GFC) and Corona Financial Crisis (CFC)

    Not all financial crises are the same. And this is more so about the two crises that we have been witness to – the 2008 Global Financial Crisis (GFC) and the current Corona Financial Crisis (CFC). The author points out the four key difference in the two crises. These four difference also mean that the solution for 2008 GFC may not be the solution for the present CFC. But why is it so? Read to know more…

    1. Origin of the two crises

    • The GFC originated in the financial sector.
    • In GFC, banks and financial intermediaries got carried away by irrational exuberance and recklessly piled on risk.
    •  CDS, CDO, MBS, ABS and various other became the villains in the GFC drama as it unfolded in the rich countries.
    • As people lost their wealth and savings in the financial meltdown, demand collapsed and growth slumped.
    • The contagion, which originated in the financial sector, spread to the real economy.
    • In contrast, the CFC came from outside the economic system.
    • The first impact came by way of a supply shock as China-centred supply chains broke down.
    • And then as countries ordered lockdowns and economies shut down, demand slumped.
    • The ensuing distress in the real economy led to distress in the financial system.

    So, how origin of the crisis matter for its resolution?

    • Restoring the faith in the financial system was key to the resolution of GFC.
    • Which meant rescue and rehabilitation of banks and other financial institutions.
    • Once that task in the financial sector was accomplished, repair of the real economy fell in place.
    • The demand came back, supply resumed and growth picked up.
    • In contrast, the central challenge in the resolution of the CFC is to beat the pandemic, and that solution has to come from science.
    • Only when there is public confidence that the incidence of the pandemic has been brought down to a low-level equilibrium, will there be a resolution in both the real and financial economies.
    • We are seeing that even during this crisis, just like in 2008, governments are coming out with fiscal stimulus packages and central banks with monetary stimulus packages.
    • But these are not solutions to the pandemic; they are just holding operations till the central problem is resolved.

    2. No one country hold key to solution

    • The second difference between the two crises arises from the asymmetry of the solutions.
    • The GFC originated in the subprime mortgage sector of the US and then, rapidly engulfed the world.
    • The CFC originated in the Hubei province of China and rapidly engulfed the world.
    • But the similarity ends there.
    • For the resolution of the GFC, restoring financial stability in the US was necessary, and a sufficient condition for restoration of financial stability everywhere.
    • But the situation with the CFC is different.
    • Every country needs to control the pandemic within its borders.
    • But that is not sufficient because the virus can hit back from across the border.
    • No country is safe until every country is safe.

    3. Policy interventions involve a dilemma

    • How the policy interventions interact with one another makes for the third difference between the two crises.
    • During the resolution of the GFC, solutions in the financial sector and in the real economy reinforced each other.
    • For example, to mitigate the crisis, the RBI cut rates and intervened in the forex market, the government extended special concessions for housing and real estate sectors to provide stimulus in the real economy.
    • There was synergy in these actions.
    • In contrast, in managing the challenge of the CFC, what we are seeing is tension between the various sets of policy actions.
    • The effort to contain the pandemic is exacerbating the challenges in both the real economy and the financial sector.
    • The more stringent the lockdown to save lives, the more extensive the loss of livelihoods.
    • Managing this tension is by far the biggest dilemma for governments battling the crisis.

    4. No single large economy to keep the world afloat

    • The global financial crisis, although it was called “global” did not affect all countries equally.
    • China was less affected even as all rich countries were in a financial meltdown.
    • In fact, one of the less acknowledged facts of the 2008 crisis is that it was the stimulus provided by China that kept the global economy afloat.
    • In contrast, now all rich and big economies are weighed down by the virus, and there is not a single large economy to keep the rest of the world afloat.

    Consider the question “Analyse the key differences in the Global Financial Crisis of 2008 and the financial crisis caused by the Covid-19.”

    Conclusion

    If pandemics are going to be more frequent, as is now suspected, it is all the more important that there is a more enforceable global protocol on early warning and information sharing. For all their differences, the GFC and CFC are similar in one respect — they both teach us life-enhancing lessons. The GFC forcefully reminded us that greed and avarice will only bring tears in the end. The CFC is teaching us that the force of nature is bigger than the combined force of our science and technology.

    Back2Basics: Credit Default Swap (CDS)

    • A credit default swap (CDS) is a type of credit derivative that provides the buyer with protection against default and other risks.
    • The buyer of a CDS makes periodic payments to the seller until the credit maturity date.
    • In the agreement, the seller commits that, if the debt issuer defaults, the seller will pay the buyer all premiums and interest that would’ve been paid up to the date of maturity.

    Collateralised Debt Obligations (CDO), MBS and ABS

    • To create a CDO, investment banks gather cash flow-generating assets—such as mortgages, bonds, and other types of debt.
    • These assets are then repackaged into discrete classes or tranches based on the level of credit risk assumed by the investor.
    • These tranches of securities become the final investment products: bonds, whose names can reflect their specific underlying assets.
    • For example, mortgage-backed securities (MBS) are comprised of mortgage loans.
    • And asset-backed securities (ABS) contain corporate debt, auto loans, or credit card debt.
    • CDOs are called “collateralized” because the promised repayments of the underlying assets are the collateral that gives the CDOs their value.
    • Mortgage-backed securities played a central role in the financial crisis that began in 2007 and went on to wipe out trillions of dollars in wealth, bring down Lehman Brothers, and roil the world financial markets.
    • In retrospect, it seems inevitable that the rapid increase in home prices and the growing demand for MBS would encourage banks to lower their lending standards and drive consumers to jump into the market at any cost.
