U.P. Hathras Stampede

Syllabus: GS2/ Governance

In News

• A stampede at a religious gathering in Hathras has claimed the lives of over 100 people.
  • Many such incidents happened in the past like Kalkaji temple’s platform collapse or the Vaishno Devi temple stampede that happened in 2022.

What is a stampede? 

• Stampedes are often described as the disruption of the orderly movement of crowds leading to injuries and fatalities.
• There are many factors like – poor event management, higher density of people allowed, or even due to natural disasters like sudden heavy rain, flood, or earthquake.

How can such events be Prevented?

• Proper risk analysis and capacity planning should be done according to the periodicity of the event, weather and terrain.
• Safety codes and communication need to be followed strongly with multiple entry and exit points, availability of emergency medical personnel, first aid kits and ambulances.

NDMA Guidelines on Crowd Management

• The National Disaster Management Authority (NDMA) has formulated guidelines on crowd management to prevent and mitigate the risks of crowd disasters at events and venues of mass gatherings. 
• Risk Assessment and Planning: Develop a comprehensive crowd management plan based on the risk assessment, outlining roles and responsibilities, communication protocols, and emergency response procedures.
• Infrastructure and Facilities: Ensure adequate space, entry/exit points, signage, lighting, and sanitation facilities at the venue.

• Emergency Response: Develop an emergency response plan for incidents like stampedes, fires, medical emergencies, or terrorist attacks. Ensure adequate medical facilities and trained personnel are available at the venue. 
• Training and Awareness: Provide training to organizers, security personnel, volunteers, and other stakeholders on crowd management techniques and emergency procedures.
• Use of Technologies: Use of technology like Artificial Intelligence (AI) and data analytics for crowd prediction and behavior analysis.

Li-Fi Technology 

Syllabus: GS3/Science and Technology

Context

• Recently, the Ministry of Defence, under the Innovations for Defence Excellence (iDEX) initiative, granted the Li-Fi Technology to address the Indian Navy’s communication challenges.

About  Light Fidelity (Li-Fi) Technology

• It is a wireless communication technology that uses visible light to transmit data.
• Unlike traditional radio frequency-based Wi-Fi, which relies on radio waves, Li-Fi leverages Light-emitting Diodes (LEDs) to create a high-speed, secure, and energy-efficient communication channel.

Working

• LEDs as Data Transmitters: Li-Fi uses LEDs (such as those used for lighting) to transmit data. These LEDs can be modulated at high speeds to encode information.
  • When an electrical signal is applied to an LED, it emits light. By varying the intensity of the light rapidly, data can be transmitted.
• Photodetectors as Receivers: Devices equipped with photodetectors (such as smartphones, laptops, or IoT devices) receive the modulated light signals.
  • The photodetectors convert the received light into electrical signals, which are then processed as data.

Advantages

• High Speed: Li-Fi can achieve data rates of several gigabits per second (Gbps), surpassing traditional Wi-Fi.
• Security: Since Li-Fi operates within the visible light spectrum, it does not penetrate walls, making it inherently secure against eavesdropping.
• No Interference: Li-Fi does not interfere with radio frequencies used by Wi-Fi or cellular networks.
• Energy Efficiency: LEDs are energy-efficient, contributing to overall energy savings.

Challenges and Considerations

• Line of Sight: Li-Fi requires a direct line of sight between the transmitter (LED) and receiver (photodetector).
• Indoor Use: Li-Fi is ideal for indoor environments, such as offices, hospitals, and smart homes.
• Integration: Integrating Li-Fi with existing infrastructure and devices remains a challenge.

Applications

• Internet Connectivity and Indoor Communication: Li-Fi can provide high-speed internet access in offices, homes, and public spaces.
• Secure Environments: Military bases, hospitals, and data centres benefit from Li-Fi’s security features.
• Underwater Communication: Li-Fi can be used for underwater communication, where RF signals are ineffective.

Recycling of Critical Mineral 

Syllabus: GS3/ Economy

Context

• The Ministry of Mines is designing a Production Linked Incentive (PLI) scheme to boost the recycling of critical minerals in India.

About

• The proposed PLI scheme aligns with policy recommendations from NITI Aayog, and complements the Battery Waste Management Rules (BWMR), 2022, which mandate phased recycling of used electric vehicle (EV) lithium-ion batteries from 2026 onwards.
• The PLI scheme will target e-waste recycling– often referred to as “urban mining”– to recover critical minerals such as lithium, copper, cobalt, graphite, chromium, and silicon.

Need for the Critical Mineral Recycling

• Waste generation: India’s e-waste generation is poised to surge, driven by rapid growth in solar and wind energy infrastructure and EV adoption.
  • The PV module waste will increase from 100 kilotons in FY23 to 340 kilotons by 2030. Additionally, 500 kt of EV batteries are expected to reach recycling units in the coming years.
• Scarce reserves: Manufacturing renewable energy technologies and transition to electric vehicles would require increasing quantities of minerals, including copper, manganese, zinc, and indium.
  • However, India does not have many of these mineral reserves, or its requirements may be higher than the availability
• Chinese dominance:

What are Critical Minerals?

• These are minerals that are essential for economic development and national security.
• The lack of availability of these minerals or the concentration of extraction or processing in a few geographical locations could potentially lead to “supply chain vulnerabilities and even disruption of supplies”.

Applications of Critical Minerals

• Clean technologies initiatives such as zero-emission vehicles, wind turbines, solar panels etc.
  • Critical minerals such as Cadmium, Cobalt, Gallium, Indium, Selenium and Vanadium and have uses in batteries, semiconductors, solar panels, etc.
• Advanced manufacturing inputs and materials such as defense applications, permanent magnets, ceramics.
  • Minerals like Beryllium, Titanium, Tungsten, Tantalum, etc. have usage in new technologies, electronics and defense equipment.
• Platinum Group Metals (PGMs) are used in medical devices, cancer treatment drugs, and dental materials.

List of Critical Minerals

• Different countries have their own unique lists of critical minerals based on their specific circumstances and priorities.
• A total of 30 minerals were found to be most critical for India, out of which two are critical as fertilizer minerals: Antimony, Beryllium, Bismuth, Cobalt, Copper, Gallium, Germanium, Graphite, Hafnium, Indium, Lithium, Molybdenum, Niobium, Nickel, PGE, Phosphorous, Potash, REE, Rhenium, Silicon, Strontium, Tantalum, Tellurium, Tin, Titanium, Tungsten, Vanadium, Zirconium, Selenium and Cadmium.

Conclusion

• This move will foster a circular economy and bolster domestic supply chains, following a lackluster response to recent auctions of critical mineral blocks.
• The International Energy Agency (IEA) estimates that by 2040, recycled copper, lithium, nickel, and cobalt from spent batteries alone could provide 10% of these minerals.  However recycling can only ease critical minerals scarcity, not solve it.

Wireless Network Architecture in Rural India

Syllabus: GS3/Infrastructure

Context

• Recently, Institute of Electrical and Electronics Engineers (IEEE) approved a wireless network architecture for affordable broadband access in rural areas, developed at IIT Bombay.

About

• The connectivity for mobile devices is enabled via a cellular (mobile) wireless network.
• A cellular network, such as a 5G network, includes a set of network equipment connected by communication links. 
• They work together to move data between different devices and to other networks, e.g., the Internet. 
• A cellular network can be divided into two sub-networks: the access network (AN) and the core network (CN).

Access and Core Networks

• The AN consists of base stations that provide wireless connectivity to mobile devices in a limited geographical area, called the coverage area. 
• The CN of a cellular network has equipment that provides connectivity to other networks, such as the Internet. 
• Unlike AN base stations, the CN operates in a central location, and possibly far from any of the base stations.
• Data from a user’s device must pass through both a base station and the CN to reach its desired destination, such as the Internet or another user’s device. 

Reasons for Low Rural Connectivity

• Urban-rural Digital Divide: Even though cellular networks seem omnipresent, their deployment and use vary significantly between urban and rural areas. This is especially true in developing countries like India.
  • According to the Telecom Regulatory Authority of India, urban tele-density in the country is 127% while the rural tele-density is 58%. 
• Lower Income: An important factor impeding the deployment and/or use of cellular networks in rural areas is the relatively lower income of the people here. A big chunk of the rural population finds mobile services unaffordable. 
• Distribution of Population: Rural areas are lower population density, populations distributed in clusters (villages) often separated by vast empty spaces, and remoteness. 

The IEEE 2061-2024 Standard

• IIT Bombay, has been working on affordable rural connectivity for many years. 
• The standard defines a wireless network architecture for affordable broadband access in rural areas. 
• The IEEE-2061 network also includes a CN and AN similar to cellular networks.
  • However, the IEEE-2061 AN is heterogenous wherein different types of base stations coexist: it includes base stations covering large coverage areas — called macro-BS — supplemented by small coverage area Wi-Fi. 
• It is different from the 5G network, where the AN is homogeneous comprising base stations of the same type and typically smaller coverage area.

• Significance: A key capability of the system is that it allows a device to move from a Wi-Fi based connectivity to a macro-BS connectivity without any service disruption.
  • As wireless systems evolve, both legacy and new technologies — including 4G, 5G, 6G, Wi-Fi and networks — will coexist and complement each other. 
  • In such a heterogeneous network, an integrated AN control functionality like the one included in the IEEE-2061 standard will help avoid issues like call drops. 

What is a middle-mile network?

• The IEEE-2061 standard proposes the use of a multi-hop wireless middle-mile network to extend connectivity to areas where optical-fibre links are not available. 
• A multi-hop wireless middle-mile provides cost-effective connectivity over long distances, eliminating the need for a costly and difficult-to-deploy optical fibre. 
• An IEEE-2061 network can flexibly use one or more technologies like satellites, or long-range Wi-Fi for the middle-mile.

Conclusion

• IEEE 2061-2024 is the second IEEE standard to come out of the research efforts of IIT Bombay. 
• If adopted, IEEE 2061 can help provide affordable connectivity to rural populations. 
• Its novel concepts, including the CN bypass, and integrated AN control may also pave the way towards a flexible and scalable mobile network in future.

Mudras in Buddhism

Syllabus: GS1/Art and Culture

Context

• Recently, the Leader of Opposition in Lok Sabha, in his first speech, invoked the ‘Abhaya Mudra’, the gesture of the raised open palm that is commonly understood as conveying reassurance and a freedom from fear.

About the Mudras in Buddhism

• Mudras are symbolic hand gestures used in Buddhist art and practice made during rituals or depicted in images of Buddhas, bodhisattvas, and tantric deities.
• These gestures convey specific ideas, evoke particular states of mind, and represent various Buddhas and bodhisattvas.

Early Depictions

• For about 500 years after the Buddha, who lived in the 6th or 5th Century BCE, the person of the great teacher was not depicted in the form of an image or sculpture.
  • At Sanchi, for instance, the Buddha is symbolised by a vacant throne or a footprint.
• The earliest physical depictions of the Buddha emerged around the turn of the first millennium.
• Gandhara Art (in present-day Pakistan and Afghanistan) and Gupta Period Art (in the Gangetic plains) featured the first Buddharupa (Buddha images).
• Four primary mudras appeared in these early depictions:
  • Abhaya Mudra: The gesture, with the raised open palm, of fearlessness, symbolising protection and reassurance.
    • Images of Tara, a popular figure in Vajrayana Buddhism, often show her with her right hand in the Abhaya Mudra.
  • Bhumisparsha Mudra: The Earth-touching gesture, representing the moment of enlightenment.
  • Dharmachakra Mudra: The wheel-turning gesture, symbolising teaching and spreading the Dharma.
  • Dhyana Mudra: The meditation gesture, reflecting inner contemplation.

Tantric Buddhism and Mudras

• Tantric Buddhism incorporated mudras into its rituals. Tantric elements like ‘Dharini’, ‘Mantra’, ‘Mudra’, ‘Yantra’, and ‘Mandala’ played a crucial role in worship.

Megafauna

Syllabus: Miscellaneous

Context

• The discovery of a 41,000-year-old ostrich nest by a team of archaeologists in Andhra Pradesh could provide key information about the extinction of megafauna in the Indian subcontinent.

About

• A team of archaeologists unearthed the world’s oldest known ostrich nest, while investigating the Prakasam site for fossils. 
• The nest has a width of 9-10 feet, and was once home to 9-11 eggs, although it was capable of holding 30-40 eggs at a time.
• This discovery gave crucial insights about the extinction of megafauna in India.

Megafauna

• While scientific literature disagrees about what constitutes megafauna, the term is generally used to describe animals weighing more than 50 kg. 
• The term was first used by the English naturalist and explorer Alfred Russel Wallace in his 1876 book, The Geographical Distribution of Animals.
• Megafauna may be classified based on their dietary type as megaherbivores (plant-eaters), mega carnivores (meat-eaters), and mega omnivores (who eat both plants and meat). 
• Ostriches are mega omnivores, with an adult ostrich weighing anywhere between 90 and 140 kg, with height between seven and nine feet.
  • The discovery in Andhra proves the presence of ostriches in southern India 41,000 years ago.
  • The earliest documented evidence of the species in the subcontinent was presented by Richard Lydekker in 1884 in the Dhok Pathan deposits in Upper Siwalik (Sivalik) Hills in present-day Pakistan. 
  • He identified this as the extinct Struthio asiaticus or the Asian ostrich, a species named in 1871 by Richard Milne-Edwards.
• There is a general consensus on the need for robust datasets to establish a better understanding of the extinction of megafauna in the subcontinent.

WHO’s Polio Eradication Missing Deadline

Syllabus: GS2/Health

Context

• The WHO’s Global Polio Eradication Initiative is set to miss its deadline of eradicating polio by the end of 2024.

About

• Polio eradication is one of the top priorities of the World Health Organisation (WHO). 
• Of the 3 strains of wild poliovirus (type 1, type 2 and type 3), wild poliovirus type 2 was eradicated in 1999 and wild poliovirus type 3 was eradicated in 2020.
  • Endemic wild poliovirus type 1 remains in two countries:  Pakistan and Afghanistan.
• But according to a recent report in Science, the virus is beginning to reappear in big cities in these two countries.
  • This reemergence is a result of vaccine hesitancy due to misinformation, conflict, poverty, and limited access to these isolated regions. 

Polio

• Poliomyelitis (polio) is a highly infectious viral disease that largely affects children under 5 years of age. 
• The virus is transmitted by person-to-person spread mainly through the faecal-oral route or, less frequently, by a common vehicle (e.g. contaminated water or food) and multiplies in the intestine, from where it can invade the nervous system and cause paralysis.
• Vaccination: There is no cure for polio, it can only be prevented.
  • Polio vaccine, given multiple times, can protect a child for life. 
  • There are two vaccines available: oral polio vaccine and inactivated polio vaccine. Both are effective and safe.
