Nominations for the World Heritage List 2020

Why in News

  • Recently, the Minister of State of Culture and Tourism has informed Lok Sabha that India has submitted two nomination dossiers namely ‘Dholavira: A Harappan City’ and ‘Monuments and Forts of Deccan Sultanate’ for inclusion in the World Heritage List for the year 2020.

Dholavira: A Harappan City

  • The City of Dholavira located in Khadir island of the Rann of Kutch (Gujarat) belonged to the mature Harappan phase.
  • It was excavated by R.S Bisht in 1985.
  • It demonstrates a highly organised system of town planning with perfected proportions, street-pattern and an efficient water conservation system that supported life for more than 1200 years (3000 BCE to 1800 BCE) against harsh hot arid climate.
    • The water conservation methods of Dholavira are unique and measures as one of the most efficient systems of the ancient world.
  • The presence of a three-tier zonation comprising of a distinct upper (citadel, bailey) and middle (having a distinct street-pattern, large scale enclosure and a ceremonial ground) towns enclosed by a lower town (with narrower streets, smaller enclosures and industrial area) – distinguishes the city of Dholavira from other metropolises of the Indus Valley Civilisation.

Monuments and Forts of Deccan Sultanate

  • The ‘Monuments of the Deccan Sultanate’ demonstrates the convergence of national and international styles of Islamic architecture and their intersections with the prevalent Hindu architecture of the period southern Indian in present-day Karnataka and Andhra Pradesh,
  • It comprises of four components namely,
    • Bahmani Monuments at Gulbarga, Karnataka
      • It primarily comprises the Gulbarga Fort with the Great Mosque in the Fort, Jami Masjid and the Haft Gumbad complex with seven tombs.

Concentration of Black Carbon on Gangotri Glacier

Why in News

According to a research done by the Wadia Institute of Himalayan Geology, the concentration of black carbon on Gangotri glacier has almost doubled in the past few years primarily because of agricultural burning and forest fires.

  • Scientists have been monitoring black carbon through two weather stations on way to Gangotri glaciers - namely Chirbasa station at a height of 3,600 m, and Bhojbasa station at a height of 3,800 m - for the last few years.
  • Wadia Institute of Himalayan Geology (WIHG) is an autonomous institution under the Department of Science & Technology. It is headquartered in Dehradun (Uttrakhand).

Gangotri Glacier

  • It is the largest glacier in Uttarakhand and is one of the sources of Ganges (Bhagirathi).
  • The Gangotri glacier originates at the northern slope of Chaukhamba range of peaks in Garhwal Himalayas.
  • Gangotri is not a single valley glacier, but a combination of several other glaciers.

Black Carbon

  • Black carbon is a kind of an aerosol. An aerosol is a suspension of fine solid particles or liquid droplets in the air.
  • Among aerosols (such as brown carbon, sulphates), Black Carbon (BC) has been recognized as the second most important anthropogenic agent for climate change and the primary marker to understand the adverse effects caused by air pollution.
  • It gets emitted from gas and diesel engines, coal-fired power plants, and other sources that burn fossil fuel. It comprises a significant portion of particulate matter or PM, which is an air pollutant.

Key Findings

  • Seasonal Variation
    • The concentration of the black carbon increases in summer months due to varied factors. Scientists have found a range of black carbon up to 4.62 micrograms per cubic metre.
    • In the non-summer months, the concentration comes down to about 2 micrograms per cubic metre.
  • Reasons for Increase in Black Carbon Concentration in Summer Season
    • Period from April to June shows remarkable increase in black carbon concentration primarily due to direct and indirect activities related to tourism.
    • Also, forest fires contribute to increasing black carbon concentration. According to the Forest Survey of India, the forest fire activity is generally reported in Uttarakhand from February to June, with a peak in fire incidences in May and June.
      • Besides man made, other reasons for forest fires in the state include lightning, friction of falling rocks and monkeys accidentally throwing stones that create sparks leading to forest fires.
      • Over 44,554 hectares of forest area has been damaged in forest fires in Uttarakhand since its formation in 2000.
    • The lowest black carbon concentration has been recorded during August followed by December, likely due to the absence of tourist activities and forest fire incidences during these months.
  • Local Sources of Black Carbon
    • Forest fires, domestic and commercial fuel wood burning, seasonal burning of crop residue and developmental activities.
    • Pollution from local, regional and global sources that accumulate over the Himalayan region and increase the concentration of black carbon.
  • Possible Impact
    • Black materials absorb more light and emit infra-red radiation which increases the temperature. So, when there is an increase in black carbon in the higher Himalayas, it will contribute to faster melting of the Himalayan glaciers.
    • In the longer run, the changes in the atmospheric composition of the high Himalayan will affect the weather pattern (such as rain and snow precipitation patterns), and accordingly natural resources and socio-economic activities of Himalayan communities.

Way Forward

  • The Black Carbon (BC) aerosols contribute significantly towards global warming due to its light-absorbing nature. Their presence in the eco-sensitive zone, such as the Himalayan glacier valleys, is a matter of serious concern and needs to be meticulously monitored.

Indigenously Developed Flow Diverters Stents

Why in News

The research team of Sree Chitra Thirunal Institute of Medical Science and Technology (SCTIMST), Thiruvananthapuram has developed an intracranial flow diverter stent for the treatment of aneurysms of the blood vessels of the brain.

  • Currently, the flow diverter stents are imported and are not manufactured in India.
  • The availability of indigenous technology will help to manufacture these stents at a much lower price within the country.
    • SCTIMST is an Institute of National Importance under the Department of Science and Technology.

Key Points

  • Flow diverters stents are deployed in the artery in the brain bearing the aneurysms to divert blood flow away from the aneurysm, thus reducing the chances of its rupture from the pressure of blood flow.
  • The weave shape of the designed stent makes it resistant to kinking or twisting when it is placed in complex-shaped arteries.
  • It is made up of Nitinol, a superelastic alloy with shape memory acquired from National AeroSpace Laboratories, Bengaluru (CSIR-NAL).
    • A shape-memory alloy is an alloy that can be deformed when cold but returns to its pre-deformed ("remembered") shape when heated.

Nitinol

  • Nitinol is a nickel-titanium alloy distinguished from other materials by its shape memory and superelastic characteristics.
  • It is discovered while searching for materials that could be used in tools for dismantling magnetic mines.
  • It is widely used in various kinds of industries but majorly used in the medical industry due to its narrow temperature range.

Brain Aneurysm

  • Brain aneurysm is also known as Intracranial aneurysm.
  • Intracranial aneurysm is a localised ballooning, bulging or dilation of arteries in the brain, caused by progressive weakening of the inner muscles of the wall of the blood vessels.
  • Spontaneous rupture of the aneurysm can result in bleeding into the space around the brain leading to paralysis, coma or death.
