The Armenian Genocide

Relevance: International relations

Context: U.S. President Joe Biden has fulfilled a long-pending American promise by recognizing the mass killings of Armenians by the Ottoman Turks in 1915-16 as “an act of genocide”, but the move has clearly infuriated Turkey, a NATO ally.

More about the Armenian genocide:

  • The Armenian Genocide is regarded as the twentieth century’s first genocide.
  • It refers to the Ottoman Empire’s systematic annihilation of Armenians from 1915 to 1917.
  • Background: Following the outbreak of the First World War in November 1914, the Ottoman Turks joined the battle, siding with Germany and the Austro-Hungarian empire.
  • The Ottoman Turks expected Armenians to support Russia in the war. As a result, the Ottoman Turks launched a massive expulsion of Armenians from the Eastern Front’s border regions.
  • Thousands of Armenian intellectuals were arrested and executed by Ottoman Turkish government officials on April 24, 1915. The Armenian Genocide began on this date.
  • Armenian families, including small children, were forced to walk for days in the Syrian and Arabian deserts without food, water, or shelter.
  • According to reports, 1.5 million Armenians died as a result of the genocide, either as a result of massacres and executions, or as a result of ill-treatment, violence, and starvation.
  • The significance of this recognition: The US government’s acknowledgement would have no legal effect on Turkey, other than causing shame and encouraging other countries to recognize the genocide as well.
  • The Armenian Genocide is officially recognized by 30 countries, according to the Armenian National Institute.

Assam Earthquake

Relevance: Geography

Context: Several houses and buildings were damaged after an earthquake of magnitude 6.4 on the Richter scale hit Assam.

What is an earthquake?

  • An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. During an earthquake, vibrations caused by the breakage of rock along a fault zone radiate outward from the point of rupture. The instrument used to record and measure these vibrations is called a
  • The location below the earth’s surface where the earthquake starts is called the hypocentre, and the location directly above it on the surface of the earth is called the

What Causes Earthquakes?

  • Tectonic plates are constantly moving due to convection currents triggered by molten lava inside the earth’s crust. This constant movement leads to either the plates sliding against each other or drifting away from each other.
  • When these plates move against each other, there is a point where they interact this point is known as a fault line. This fault line is sometimes known as a fracture in the earth’s crust.
  • The moment the plates begin to move, the potential energy, commonly known as stored energy, is released from the hypocentre. The outcome is an earthquake.

Types of Earthquakes

  • Tectonic Earthquakes– The tectonic plates are capable of moving slowly and gradually. The movement of these plates occurs in different forms; towards each other, away from each other, sliding past each other or colliding with each other. A huge tremor occurs when 2 moving tectonic plates slide over one another. This type of earthquake is known as a tectonic earthquake.
  • Volcanic Earthquakes– These are less prevalent. They typically take place before or after an eruption.
  • Explosion Earthquakes– These are caused by nuclear explosions. They are, essentially, man triggered kinds of earthquakes and represent the biggest impact of modern-day nuclear war.
  • Collapse Earthquakes- They are sometimes referred to as mine bursts. Collapse earthquakes are instigated by the pressure generated within the rocks. This kind of earthquake leads to the collapse of the roof of the mine instigating more tremors.

What is the Richter scale?

  • The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes.
  • The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.
  • On the Richter scale, magnitude is expressed in whole numbers and decimal fractions.
  • In theory, the Richter scale has no upper limit, but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6.

Advanced Chaff Technology

Relevance: Science and Technology

Context: Defence Research and Development Organisation (DRDO) develops Advanced Chaff Technology to safeguard naval ships from missile attack.

About Advanced Chaff Technology

  • Chaff is an electronic countermeasure technology used by militaries worldwide to protect naval ships or other sensitive targets from radar and radio frequency (RF) guiding mechanisms of the enemy missile.
  • The chaff rockets deployed in the air reflect as multiple targets for the missile guidance systems and deflecting adversary missiles, thus protecting their assets.
  • Chaff is thin pieces of aluminium, metallized glass fibre or plastic, which either appears as a cluster of primary targets on radar screens or swamps the screen with multiple returns.
  • DRDO’s facility Defence Laboratory Jodhpur (DLJ) has indigenously developed three variants of this critical technology, namely Short Range Chaff Rocket (SRCR), Medium-Range Chaff Rocket (MRCR) and Long Range Chaff Rocket (LRCR).
  • A small quantity of chaff material, when deployed in the air, acts as a decoy and deflects the enemy’s missiles, thereby keeping India’s ships safe.


Difference between chaff and flares:

  • Both chaff and flares are defensive countermeasures deployed by military aircraft. The purpose is to confuse radar-guided or infrared-guided anti-aircraft missiles fired so that they could be diverted.
  • Chaff is composed of much small aluminium or zinc coated fibres stored on-board the aircraft in tubes. In case the aircraft feels threatened by any radar tracking missiles, chaff is ejected into the turbulent wake of air behind the plane.
  • Flares however are useful in distracting the heat seeking missiles. Mostly magnesium pellets are ejected from the tubes to ignite while being followed by an aircraft behind. The flares burn at more than 2000 Fahrenheit and emit high amounts of infrared light.


About DRDO

  • DRDO is the R&D wing of the Ministry of Defence, with a vision to empower India with cutting-edge defence technologies and a mission to achieve self-reliance in critical defence technologies and systems, while equipping our armed forces with state-of-the-art weapon systems and equipment following requirements laid down by the three Services.
  • DRDO was formed in 1958 from the amalgamation of the then already functioning Technical Development Establishment (TDEs) of the Indian Army and the Directorate of Technical Development & Production (DTDP) with the Defence Science Organisation (DSO). Today, DRDO is a network of more than 50 laboratories.
  • DRDO is India’s largest research organisation. It has a network of laboratories engaged in developing defence technologies covering various fields, like aeronautics, armaments, electronics, land combat engineering, life sciences, materials, missiles, and naval systems.

Oxygen Concentrators

Relevance: Science and Technology

Context: PM CARES to fund 1 lakh portable oxygen concentrators.

What are Oxygen Concentrators?

  • An oxygen concentrator is a medical device that concentrates oxygen from ambient air. Atmospheric air has about 78 percent nitrogen and 21 percent oxygen, with other gases making up the remaining 1 per cent.
  • The oxygen concentrator takes in this air, filters it through a sieve, releases the nitrogen back into the air, and works on the remaining oxygen.
  • This oxygen, compressed and dispensed through a cannula, is 90-95 per cent pure. A pressure valve in concentrators helps regulate supply, ranging from 1-10 litres per minute.

How are concentrators different from oxygen cylinders and Liquid medical oxygen (LMO)?

  • Oxygen concentrators are the easiest alternatives to cylinders but can only supply 5-10 litres of oxygen per minute (critical patients may need 40-50 litres per minute) and are best suited for moderately ill patients.
  • Concentrators are portable and unlike LMO that need to be stored and transported in cryogenic tankers, need no special temperature. And unlike cylinders that require refilling, concentrators only need a power source to draw in ambient air.

About PM CARES Fund

  • The Prime Minister’s Citizen Assistance and Relief in Emergency Situations Fund were created on 28 March 2020, following the COVID-19 pandemic in India. The fund will be used for combat, and containment and relief efforts against the coronavirus outbreak and similar pandemic like situations in the future.
  • Donations to PM CARES Fund would qualify for 100% exemption under the Income Tax.
  • Donations to PM CARES Fund will also qualify to be counted as Corporate Social Responsibility (CSR) expenditure under the Companies Act, 2013.
  • PM CARES Fund has also got exemption under the Foreign Contribution Regulation Act, 2010 and a separate account for receiving foreign donations has been opened.


  • To undertake and support relief or assistance of any kind relating to a public health emergency or any other kind of emergency, calamity or distress, either man-made or natural, etc.,
  • To render financial assistance, provide grants of payments of money or take such other steps as may be deemed necessary by the Board of Trustees to the affected population.

Constitution of the Trust:

  • Prime Minister is the ex-officio Chairman of the PM CARES Fund and Minister of Defence, Minister of Home Affairs and Minister of Finance, Government of India are ex-officio Trustees of the Fund.
  • The Chairperson of the Board of Trustees (Prime Minister) shall have the power to nominate three trustees to the Board of Trustees who shall be eminent persons in the field of research, health, science, social work, law, public administration and philanthropy.
  • Any person appointed a Trustee shall act in a pro bono capacity.

Breakthrough infections

Relevance: Health-related issues

Context: Breakthrough infections amongst fully vaccinated healthcare workers in Kerala is emerging as a new concern.

What are Breakthrough infections?

  • Vaccines are hailed to be the greatest weapons against the invisible enemy SARS-CoV-2 that causes COVID-19. However, there remains a bleak possibility that the virus may find a way to attack those who have already been inoculated. This scenario is known as ‘vaccine breakthrough infection’ where the pathogen infiltrates the immune response generated by the vaccines.
  • The chances of infection after full vaccination are relatively less. In India, just 0.04% of such re-infection cases have been reported so far, according to the country’s apex medical body the Indian Council of Medical Research (ICMR).


Why do breakthrough infections happen?

  • No vaccine is 100% effective against any viral disease. Hence, all types of vaccine, be it Moderna or Pfizer or Covaxin and have small chances of causing breakthrough infection. In addition, it must be noted that vaccines are a shield against severe forms of COVID-19 and not an infection. They reduce the chances of disease-related mortality and help patients recover fast.
  • It takes at least two weeks for vaccines to develop an immune response after getting the shots. Therefore, during this period, the chances of contracting the virus are equivalent to the person who has not received the shots.
  • There are also chances that the emerging mutant forms of the coronavirus may trigger infection again and evade the defence response induced by vaccines.

About ICMR

  • The Indian Council of Medical Research (ICMR), New Delhi, the apex body in India for the formulation, coordination and promotion of biomedical research, is one of the oldest medical research bodies in the world.
  • The ICMR is funded by the Ministry of Health & Family Welfare. The Council’s research priorities coincide with the National health priorities, such as control and management of communicable diseases, fertility control, maternal and child health, control of nutritional disorders, etc.
  • ICMR continues to provide extramural funding to strengthen research capabilities within the institutes of the council as well as other research institutes, medical colleges and Non-Governmental Organizations for various research projects.
  • Mission of ICMR:
  • Generate, manage and disseminate new knowledge.
  • Increase focus on research on the health problems of the vulnerable, the disadvantaged and marginalized sections of the society.
  • Harness and encourage the use of modern biology tools in addressing the health concerns of the country.
  • Encourage innovations and translation related to diagnostics, treatment, methods/vaccines for the prevention of diseases.
  • Inculcate a culture of research in academia especially medical colleges and other health research institutions by strengthening infrastructure and human resources.
