Fuel Cell Technology for Disaster Management

Why in News

The International Advanced Research for Powder Metallurgy & New Materials (ARCI), Hyderabad has developed Polymer Electrolyte Membrane Fuel Cells (PEMFC).

  • ARCI is an autonomous Research and Development (R&D) Centre of the Department of Science and Technology (DST).

Polymer Electrolyte Membrane Fuel Cells

  • PEMFC convert the chemical energy stored in hydrogen fuel directly and efficiently to electrical energy with water as the only byproduct without the need for grid power as required by conventional battery backup systems.
  • Potential: To reduce energy use, pollutant emissions and dependence on fossil fuels and providing sustainable electricity.
  • Advantage: Operational capability at low-temperatures with applications in decentralised power generation systems.

Key Points

  • The ARCI has developed in-house PEMFC systems in the power range of 1 to 20 kiloWatt (kW) at its Centre for Fuel Cell Technology, Chennai.
  • ARCI is planning to set up a PEMFC system at Tamil Nadu State Emergency Operation Centre (TN SEOC) as a disaster management measure.
    • Tamil Nadu is generally affected by five to six cyclones every year, of which two to three are severe.
  • In general, Emergency Operation Centres (EOC) backed with a 10 kW system along with fuel cell stack, air moving subsystems, power control devices and control and monitoring system is being planned as a natural disaster management measure.
    • EOCs have been set up in the states as per the National disaster Management Guidelines.
    • An EOC is the hub to coordinate various activities during emergencies. The basic functions of the EOC includes collection and dissemination of early warnings on disaster, ensuring administrative and community preparedness and coordinating with all emergency support functions.
    • Fuel cell systems in EOCs offer a potential benefit in terms of providing sustainable electricity.
  • India is vulnerable to a large number of disasters.
    • Disaster risks in India are further compounded by increasing vulnerabilities related to changing demographics and socio-economic conditions, unplanned urbanization, development within high-risk zones, environmental degradation, climate change, geological hazards, epidemics and pandemics.
    • There has been a paradigm shift in the focus of Disaster Management, from response-centric (rescue, relief, rehabilitation, and reconstruction) to laying greater emphasis on the other elements of disaster management cycle (prevention, mitigation, and preparedness) as a means to avert the impact of future emergencies.

New Test with Quantum Coins & Computers for Quantum Sensing

Why in News

Key Points

  • The test uses entanglement to test the fairness of the quantum coin. Their strategy enables better discrimination between quantum states. Such an advantage is valuable in quantum sensors
  • This is a significant contribution to quantum state discrimination and an essential aspect of quantum information science which is expected to influence quantum sensing.

Quantum Information and Quantum Computing Technology

  • The domain of Quantum Information and Quantum Computing Technology is a growing area of research which is expected to influence Data Processing, which in turn, plays a central role in our lives in this Information Age.
  • For instance, bank transactions, online shopping and so on crucially depend on the efficiency of information transfer.
  • Thus the work on quantum state discrimination is expected to be valuable in people’s lives in the current era.

Qubit

  • A quantum bit, or qubit, is the basic unit of information for a quantum computer, analogous to a bit in ordinary machines.
  • But unlike a bit, which can have the value 0 or 1, a qubit can take on an infinite number of values.

Quantum computer

  • A quantum computer is any device for computation that makes direct use of distinctively quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data.
  • Superposition means that each qubit can represent both a ‘1’ and a ‘0’ at the same time
  • Quantum entanglement occurs when two particles become inextricably linked, and whatever happens to one immediately affects the other, regardless of how far apart they are.
    • Entanglement is a special type of correlation that exists in the quantum world with no classical counterpart.

Gender Parity Index: UNESCO

  • Gender Parity Index in primary, secondary and tertiary education is the ratio of the number of female students enrolled at primary, secondary and tertiary levels of education to the number of male students in each level.
  • In short, GPI at various levels reflect equitable participation of girls in the School system.
  • GPI is released by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as a part of its Global Education Monitoring Report.
  • A GPI of 1 indicates parity between the sexes; a GPI that varies between 0 and 1 typically means a disparity in favour of males; whereas a GPI greater than 1 indicates a disparity in favour of females.
  • India’s GPI for the year 2018-19 at different levels of School Education is as under:
    • Primary Education: 1.03
    • Upper Primary Education: 1.12
    • Secondary Education: 1.04
    • Higher Secondary Education: 1.04
  • India’s GPI indicates that the number of girls is more than the number of boys at all levels of school Education.
  • In 2018-19, the Ministry of Human Resource Development launched the ‘Samagra Shiksha’ scheme. It is a Centrally Sponsored Scheme.
    • It is an overarching programme for the school education sector extending from pre-school to class XII and aims to ensure inclusive and equitable quality education at all levels of school education.
    • One of its objectives is to bridge social and gender gaps in school education.
    • To provide quality education to girls from disadvantaged groups, Kasturba Gandhi BalikaVidyalayas (KGBVs) have been sanctioned in Educationally Backward Blocks (EBBs) under SamagraShiksha.
    • KGBVs are residential schools from class VI to XII for girls belonging to disadvantaged groups such as SC, ST, OBC, Minority and Below Poverty Line (BPL).

Note: Educationally Backward Blocks are drawn on the basis of twin criteria of Female Literacy Rate and Gender Gap in Literacy. However, some blocks have been identified only on the basis of Female Literacy Rate also.

Freedom in the World 2020 Report

Why in News

The Freedom in the World 2020 report has ranked India at the 83rd position along with Timor-Leste and Senegal.

  • The report is released by Freedom House, a U.S.-based watchdog, which has been tracking global political and civil liberties for almost half a century.
  • The report derives its methodology from the Universal Declaration of Human Rights, adopted by the United Nations General Assembly (UNGA) in 1948.
  • It covers 195 countries, awarding scores based on-
    • Political rights indicators such as the electoral process, political pluralism and participation and government functioning.
    • Civil liberties indicators related to freedom of expression and belief, associational and organisational rights, the rule of law and personal autonomy and individual rights.

Key Highlights of the Report

  • India’s score fell by four points to 71, the worst decline among the world’s 25 largest democracies.
    • India scored 34 out of 40 points in the political rights category, but only 37 out of 60 in the civil liberties category, for a total score of 71, a drop from last year’s score of 75.
    • India is near the bottom of the pile among the countries categorised as “Free”, with only Tunisia receiving a lower score.
  • The scrapping of Article 370, the National Register of Citizens (NRC) and the Citizenship (Amendment) Act, 2019 (CAA), as well as the crackdown on mass protests have been listed as the main signs of declining freedom.
    • The report criticised the internet blackout in Kashmir, terming it the longest shutdown ever imposed by a democracy.
    • It highlighted that freedom of expression (Article 19) is under threat in India, with journalists, academics and others facing harassment and intimidation when addressing politically sensitive topics.
  • The report noted that India has long been seen as a democratic counterweight to China and hence a strategic partner for the United States in the region.
    • However, that view is changing, with India attracting criticism similar to that levied against China.
