A) Science and Technology, Defence, Space

  1. Ultraviolet Germicidal Irradiation System (PIB)
  • Context:After the successful trials of UV-C Disinfection Technology in Railways, Parliament House and AC Buses, it is now open for general roll-out for use by common masses.
  • UV-C technology developed by the Ministry of Science & Technology through CSIR-CSIO (Central Scientific Instruments Organisation) is totally effective for mitigation of airborne transmission of SARS-COV-2 and will also remain relevant in post-COVID era.


  • Irradiation is the process by which an object is exposed to radiation.
  • Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.
  • UVGI is used in a variety of applications, such as food, air, and water purification.

What is UV Radiation?

  • All radiation is a form of energy, most of which is invisible to the human eye.
  • UV radiation is only one form of radiation and it is measured on a scientific scale called the electromagnetic (EM) spectrum.
  • UV radiation is the portion of the EM spectrum between X-rays and visible light.

How is radiation classified on the electromagnetic spectrum?

  • Electromagnetic radiation is all around us, though we can only see some of it.
  • All EM radiation (also called EM energy) is made up of minute packets of energy or ‘particles,’ called photons, which travel in a wave-like pattern and move at the speed of light.
  • At the bottom of the spectrum radio waves have photons with low energies, so their wavelengths are long with peaks that are far apart.
  • The photons of microwaves have higher energies, followed by infrared waves, UV rays, and X-rays.
  • At the top of the spectrum, gamma rays have photons with very high energies and short wavelengths with peaks that are close together.

What are the different types of UV radiation?

  • The most common form of UV radiation is sunlight, which produces three main types of UV rays:
  • UVA
  • UVB
  • UVC
  • UVA rays have the longest wavelengths, followed by UVB, and UVC rays which have the shortest wavelengths.
  • While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the Earth’s ozone layer.
  • So, most of the UV rays you come in contact with are UVA with a small amount of UVB.
  • UVB rays have a short wavelength that reaches the outer layer of your skin (the epidermis)
  • UVA rays have a longer wavelength that can penetrate the middle layer of your skin (the dermis)
  • Out of three types of UV radiations named UVA, UVB and UVC, short wavelength UVC damages and alters DNA of all potentially harmful microbes, including viruses, making them incapable of replication.

What effect does UV radiation have on my body?

  • Both UVA and UVB rays can cause damage to your skin.
  • Sunburn is a sign of short-term overexposure, while premature aging and skin cancer are side effects of prolonged UV exposure.
  • Sunlight is not the only source of UV radiation you may encounter. Other sources include:
  • Tanning booths
  • Mercury vapor lighting (often found in stadiums and school gyms)
  • Some halogen, fluorescent, and incandescent lights
  • Some types of lasers

Are there health benefits of exposure to UV radiation?

  • Exposure to UVB radiation helps the skin produce a type of vitamin D, (vitamin D3), which plays an important role – along with calcium – in bone and muscle health.
  • The sun’s ultraviolet B (UVB) rays hit cholesterol in the skin cells, providing the energy for vitamin D synthesis to occur.
  • However, the amount of UVB exposure needed to obtain a benefit depends on several factors.

Many factors determine how much UV you are exposed to, including:


  • UV rays are strongest in areas close to the equator.
  • Because the sun is directly over the equator, UV rays only travel a short distance through the atmosphere to reach these areas.
  • UV radiation is also the strongest near the equator because ozone in these areas is naturally thinner, so there is less to absorb the UV radiation.


  • Higher altitudes have greater UV exposure because there is less atmosphere to absorb UV rays.

Time of Year

  • During the summer months the sun is in a more direct angle, resulting in a greater amount of UV radiation.

Time of Day

  • UV is most intense at noon when the sun is at its highest point in the sky, and UV rays have the least distance to travel through the atmosphere.

Weather Conditions

  • Many people believe that you cannot get sunburned on a cloudy day; this is simply not the case.
  • Even under cloud cover it is possible to damage your skin and eyes, and cause long-term damage.
  • It is important that you protect yourself with sunscreen, even in cloudy weather.


  • UV exposure is also greater in areas of snow, sand, pavement, grass, and water due to the reflective properties of these surfaces.

Disinfection by Ultraviolet Light

  • For the past 100 years science has recognized the bactericide effects of the ultraviolet area of the electromagnetic spectrum.
  • The specific wavelengths responsible for this reaction are situated between 240 – 280 nanometers (referred to as nm) with a peak wavelength at 265 nm. They are known as UV-C.
  • When a micro-organism’s (most viruses, bacteria, spores, cysts etc.)genetic material (DNA and RNA) is exposed to UV-C, the nuclei of the cells are modified, due to photolytic processes. In result, cell division and, by extension, reproduction is prevented.
  • It can be used to disinfect liquids, surfaces and even gases/air.
  • UV disinfection is a physical process rather than a chemical disinfectant.
  • UV disinfection has a shorter contact time when compared with other disinfectants.
  • However, there is at least one disadvantage. Organisms can sometimes repair and reverse destructive effects of UV through a “repair mechanism,” known as photoreactivation, or in the absence of light known as “dark repair.”

Can UVC help prevent COVID-19 transmission by reducing contamination?

  • Based on existing evidence, we believe so. Here’s why:
  • All bacteria and viruses tested to date (many hundreds over the years, including other coronaviruses) respond to UV disinfection.
  • Some organisms are more susceptible to UV-C disinfection than others, but all tested so far do respond at the appropriate doses.
  • UVC disinfection is often used with other technologies in a multibarrier approach to ensure that whatever pathogen is not “killed” by one method (say filtering or cleaning) is inactivated by another (UV-C).


  1. Livestock Health and Disease Control (LH&DC) Programme (TH, pg 6)
  • Context: Livestock farmers are often compelled to travel far from their villages whenever their animals need treatment — a scenario that adversely impacts the longevity and the productivity of their livestock.
  • To mitigate this problem, the Government has identified a slew of measures within the revised provisions of the Livestock Health and Disease Control (LH&DC) programme; here, a major focus has been on the ‘Establishment and Strengthening of Veterinary Services – Mobile Veterinary Units (MVUs)’.

  • The bacteria can also be spread through the air or contact with an open wound.

Peste des Petits Ruminants (PPR)

  • Peste des Petits Ruminants (PPR), also known as sheep and goat plague, is a highly contagious animal disease affecting small ruminants.
  • Once introduced, the virus can infect up to 90 percent of an animal heard, and the disease kills anywhere from 30 to 70 percent of infected animals.
  • The PPR virus does not infect humans.
  • PPR was first described in 1942 in Côte d’Ivoire.

C) Art, Culture and History

  1. Kathak and its Lucknow Gharana (IE)
  • Context:Pandit Birju Maharaj a renowned Kathak dancer of Lucknow Gharana dies at the age of 83.


  • Native to North India, Kathak is one of the Indian classical dance forms.
  • Kathak originated within Hindu temples as a storytelling device for portraying the epic tales from Hindu scriptures.
  • This performing art also incorporates legends from ancient mythology and tales from Mahabharata and Ramayana, other scriptures especially from the life of Lord Krishna.
  • Poetry was combined with rhythmic movement to aid in the worshipful storytelling.
  • The origin of Kathak is traditionally attributed to the traveling bards in the of ancient northern India known as Kathakars or storytellers
  • During the medieval period, Kathak became an established part of court culture, performed under the patronage of India’s Persian kings and Mughal Emperors.
  • One medieval ruler Wajid Ali Shah nawab of Awadh (Lucknow)– a poet and dancer himself, Shah paid special attention to the emotional expressiveness of the dance. Out of his court came a stylization of Kathak that is today known as the Lucknow gharana, or school.
  • Kathak is the only form of classical dance wedded to Hindustani or the North Indian music.
  • It is usually performed solo by both male and female dancers.
  • The focus is more on footwork; the movements are skillfully controlled and performed straight legged by dancers wearing ankle-bells.
  • The Vaishnavite cult which swept North India in the 15th century and the resultant bhakti movement contributed to a whole new range of lyrics and musical forms.
  • The Radha-Krishna theme proved immensely popular alongwith the works of Mirabai, Surdas, Nandadas and Krishnadas.

Kathak developed during the Bhakti movement.

  • The Kathakars communicate stories through rhythmic foot movements, hand gestures, facial expressions and eye work.
  • Three specific forms of this genre that is three gharanas (schools), which mostly differ in emphasis given to footwork versus acting, are more famous namely, the Jaipur gharana, the Benaras gharana and the Lucknow gharana.
  • Imminent personalities associated with Kathak include among others the founders of the different gharanas namely Bhanuji of the Jaipur Gharana; Janaki Prasad of the Benaras Gharana and Raja Chakradhar Singh of the Raigarh Gharana.

Brief about Lucknow Gharana

  • Yemen crisis: Who is fighting whom?
  • Yemen, one of the Arab world’s poorest countries, has been devastated by a civil war.
  • How did the war start?
  • Failed political transition following an Arab Spring uprising that forced its long-time authoritarian president, Ali Abdullah Saleh, to hand over power to his deputy Abdrabbuh Mansour Hadi, in 2011.
  • President Hadi struggled to deal with a variety of problems, including
  • attacks by al-Qaeda,
  • a separatist movement in the south,
  • the continuing loyalty of many military officers to Mr Saleh, as well as
  • corruption, unemployment and food insecurity.
  • The Houthi movement (by Yemen’s Zaidi Shia Muslim minority) took advantage of the new president’s weakness by taking control of their northern heartland of Saada province and neighbouring areas and later forcing Mr Hadi to flee to Riyadh where he currently heads an ‘internationally recognised’ but largely ineffective government of Yemen.
  • Yemen’s internationally-backed government of Abdrabbuh Mansur Hadi, the Saudi ally, is controlling the south, though Mr. Hadi is running the purported administration from Saudi Arabia.
  • Disillusioned with the transition, many ordinary Yemenis – including Sunnis – supported the Houthis.
  • Alarmed by the rise of Houthis – believed to be backed militarily by regional Shia power Iran, Saudi Arabia and other mostly Sunni Arab states (UAE, Bahrain, Kuwait, Qatar, Jordan, Sudan, Egypt-mostly Sunni powers) began an air campaign (“Operation Decisive Storm”)aimed at restoring Mr Hadi’s government.
  • The coalition received logistical and intelligence support from the US, UK and France.
  • Four years on, the civil war has ground to a stalemate, with the al-Houthis hunkering it out in the north.
  • The United Nations has described Yemen to be currently in the grip of the world’s worst humanitarian catastrophe, with over 11,000 deaths and 3 million internally displaced.


  • Yemen borders both Saudi Arabia and Oman.
  • Yemen borders both Red Sea and Gulf of Aden.
  • While almost all Yemenis are Muslims, the population in the north is mostly Zaidi which is closer to the Shia sect followed in Iran.
  • The southerners are mostly Sunnis akin to a majority of the Gulf Cooperation Council (GCC) citizens.
