  • Zoonotic Diseases: Medical Sciences Involved & Preventive Measures

    Nipah breaks out again in Kerala

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Nipah Virus

    Mains level: NA

    nipah

    Central Idea

    • The reappearance of Nipah infection in Kerala, with two confirmed deaths and two individuals under treatment, has raised concerns about this lethal viral disease.
    • Nipah, while not as contagious as COVID-19, is significantly more deadly, with a case fatality rate ranging from 40% to 75%.

    What is Nipah Virus Infection?

    • Nipah is a zoonotic disease, meaning it is transmitted to humans through infected animals or contaminated food.
    • Direct person-to-person transmission through close contact with an infected individual is also possible.
    • Symptoms include fever, headache, cough, sore throat, difficulty in breathing, and vomiting.
    • In severe cases, Nipah infection can progress to disorientation, drowsiness, seizures, and encephalitis (brain swelling), ultimately leading to coma and death.

    Transmission of Nipah Virus

    • Historical Outbreaks: The Nipah virus was first reported in Malaysia (1998) and Singapore (1999), deriving its name from a Malaysian village where it was first isolated. The primary mode of transmission from animals to humans is through the consumption of contaminated food. This can occur via the consumption of raw date palm sap or fruit contaminated with saliva or urine from infected bats.
    • Animal Host Reservoir: Fruit bats, commonly known as flying foxes, are the known hosts of the virus. They transmit it to other animals like pigs, dogs, cats, goats, horses, and sheep. Human infection usually occurs through direct contact with these animals or the consumption of food contaminated by their saliva or urine. Human-to-human transmission is also documented, particularly in families and healthcare settings.

    Nipah Virus Spread and Mortality

    • Slow Spread: Unlike the rapid transmission of SARS-CoV-2, the Nipah virus spreads more slowly. However, its high mortality rate is a significant concern.
    • High Mortality: During outbreaks, Nipah has shown a mortality rate as high as 68-75%. For example, in the 2001 Siliguri outbreak, 45 of the 66 infected individuals succumbed to the virus. Similarly, during the 2018 Kerala outbreak, 17 of the 18 confirmed patients died.
    • Localized Outbreaks: Notably, Nipah outbreaks have remained localized and were contained relatively quickly. The virus’s limited infectiousness and low human-to-human transmission contribute to this containment.
    • Reproductive Number (R0): Studies indicate an R0 of about 0.48 for Nipah outbreaks, signifying a slow rate of transmission within the population. An R0 value below one suggests that an infected person does not infect more than one other individual, leading to a relatively rapid end to the outbreak.
    • High Death Rates Limit Transmission: The virus’s high death rates also play a role in restricting its transmission.

    Non-Reciprocity: The physics of letting waves go one way but not the other

    Prelims Only | Science Tech | Mains Paper 3: Achievements Of Indians In S&T

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Reciprocity Principle

    Mains level: NA

    reciprocity

    Central Idea

    • Reciprocity, a fundamental principle of physics, dictates that if a signal can travel from Point A to Point B, it can also journey from Point B to Point A.
    • This intuitive concept holds significance in various aspects of daily life and serves as the basis for many technological breakthroughs and challenges.

    Exploring Reciprocity

    • The Principle Defined: Reciprocity posits that a signal transmitted from a source (Point A) to a destination (Point B) can also travel in the reverse direction by merely swapping the positions of the source and destination.
    • Everyday Analogies: Familiar scenarios, such as shining a torchlight or observing an object under a streetlight, exemplify reciprocity in action.
    • Counterintuitive Instances: Some situations defy intuition, like interrogation scenes in movies where one party can see through a window while the other cannot, or observing someone walking in darkness.

    Applications in Antennas and Beyond

    • Antennas: Reciprocity plays a pivotal role in antenna technology, enabling both the transmission and reception of signals. Engineers utilize reciprocity to assess antennas’ reception quality, simplifying testing processes for radar, sonar, seismic surveys, and MRI scanners.
    • Challenges in Spying: While reciprocity aids signal reception, it poses challenges in espionage, as it allows signals to be captured from an enemy base while potentially revealing one’s own location.
    • One-Way Traffic: To counteract reciprocity, scientists employ devices composed of components with specific properties. These devices break reciprocity, enabling signals to travel in one direction only.

    Diverse Ways to Break Reciprocity

    • Magnet-Based Non-Reciprocity: Utilizing wave plates and Faraday rotators, this method disrupts reciprocity for electromagnetic waves.
    • Modulation: By continuously altering a medium’s parameters in time or space, modulation offers a means to control signal transmission.
    • Nonlinearity: Varying a medium’s properties based on signal strength and direction introduces nonlinearity, another avenue to break reciprocity.

    Revolutionizing Technologies

    • Quantum Computing: Non-reciprocal devices find applications in quantum computing, where they amplify signals to detect quantum states effectively.
    • Miniaturization: The trend towards nanoscale and microscale devices includes non-reciprocal components, some as small as a strand of hair divided by a thousand. These miniature devices promise contributions to fields like self-driving cars, where efficient signal monitoring is essential for safety.

    Greshams Law: What happens when governments fix Currency Exchange Rates?

    Prelims Only | Economics | Mains Paper 3: Effects Of Liberalization On The Economy, Changes In Industrial Policy and their effects on Industrial Growth

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Gresham's Law

    Mains level: Not Much

    gresham's law

    Central Idea

    • The law, named after English financier Thomas Gresham, came into play most recently during the economic crisis in Sri Lanka last year.
    • The Central Bank of Sri Lanka has fixed the exchange rate between the Sri Lankan rupee and the U.S. dollar

    About Gresham’s Law

    • Thomas Gresham: The law is named after Thomas Gresham, an English financier who advised the English monarchy on financial matters. It extends beyond paper currencies and applies to commodity currencies and various goods.
    • Bad money drives out good: This maxim illustrates a phenomenon that occurs when government-fixed exchange rates diverge from market exchange rates, causing undervalued currency to be withdrawn from circulation.
    • Arbitrarily Fixed Prices: Gresham’s Law operates whenever governments arbitrarily set prices, causing a commodity to become undervalued compared to its market exchange rate. This undervaluation drives the commodity out of the formal market.
    • Black Market: In such scenarios, the only way to acquire the undervalued commodity is through the black market, as it is no longer available through official channels.
    • Goods Outflow: Countries can also experience the outflow of certain goods when their prices are forcibly undervalued by the government.

    Application to Commodity Money

    • Gold and Silver Coins: Gresham’s Law is particularly evident when a government fixes the exchange rate of commodity money, like gold and silver coins, well below their market value. In response, people may hoard or melt these coins to obtain their intrinsic value, which is higher than the government-set rate.

    Recent Example in Sri Lanka

    • Economic Crisis in Sri Lanka: Gresham’s Law was observed during the economic crisis in Sri Lanka, where the central bank fixed the exchange rate between the Sri Lankan rupee and the U.S. dollar.
    • Rupee Overvaluation: The government mandated that the price of the U.S. dollar should not exceed 200 Sri Lankan rupees, even though the black market rate indicated a higher value. This overvaluation of the rupee led to a decline in the supply of dollars and pushed the U.S. dollar out of the formal foreign exchange market.
    • Black Market Transactions: Individuals seeking U.S. dollars for foreign transactions were compelled to purchase them from the black market at rates exceeding 200 Sri Lankan rupees per dollar.

    Conditions for Gresham’s Law to Apply

    • Government-Imposed Fixed Rates: Gresham’s Law operates when government authorities establish and enforce fixed exchange rates between currencies.
    • Effective Implementation: Effective enforcement of these rates by authorities is essential for the law to take effect.

    Anti-thesis Concept: Thiers’ Law

    • “Good Money Drives Out Bad”: In the absence of government-imposed exchange rate fixes, the opposite phenomenon occurs. People tend to abandon currencies they perceive as of lower quality in favour of those they consider better, leading to the dominance of “good money.”
    • Thiers’ Law: This concept, known as Thiers’ Law and named after French politician Adolphe Thiers, complements Gresham’s Law.

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Disaster Management

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Disaster Management

    Mains level: Not Much

    Central Idea

    • In the wake of natural disasters, states often request assistance from the central government.
    • Himachal Pradesh CM recently requested for a special disaster relief package and urged the designation of the calamity as a ‘national disaster.’

    Natural Disaster Mitigation in States

    • Legal Framework: The 2005 Disaster Management Act provides the legal framework for addressing disasters, whether natural or man-made.
    • Defining disaster: It defines a “disaster” as an event causing substantial loss of life, human suffering, property damage, or environmental degradation beyond the community’s coping capacity.
    • National Disaster Management Authority (NDMA): The Act established the NDMA, headed by the Prime Minister, and State Disaster Management Authorities (SDMAs) led by Chief Ministers. These bodies, along with district-level authorities, form an integrated disaster management setup in India.
    • National Disaster Response Force (NDRF): The Act led to the creation of the NDRF, comprising several battalions or teams responsible for on-ground relief and rescue operations in various states.

    Understanding the National Disaster Relief Fund (NDRF)

    • Mention in the Act: The NDRF is referenced in the 2005 Disaster Management Act and plays a crucial role in providing disaster relief.
    • State Disaster Relief Funds (SDRFs): States have their own SDRFs, which are the primary funds available for responding to notified disasters. The Central Government contributes 75% to SDRFs in general states and 90% in northeastern and Himalayan states.
    • Utilization of SDRFs: SDRFs are allocated for immediate relief efforts following notified calamities, including cyclones, droughts, earthquakes, fires, floods, tsunamis, and more.
    • Central Assistance: In the event of a severe calamity where state SDRF funds are insufficient, additional central assistance can be provided by the National Disaster Response Fund (NDRF).

    Who determines a Severe Calamity?

    • Procedure: States follow a specific procedure to classify a calamity as “severe.” This involves submitting a memorandum detailing sector-wise damage and fund requirements. An inter-ministerial central team assesses the damage on-site.
    • Committee Approval: Specific committees review these assessments and submit reports. A High-Level Committee must approve the immediate relief amount to be released from the NDRF.
    • Criteria: The classification of a calamity as “severe” considers factors such as intensity, magnitude, assistance needs, and more.

    Additional Funds for Disaster Mitigation

    • Funds Allocation: Funds for NDRF and SDRFs, allocated for preparedness, mitigation, and reconstruction, are part of budgetary allocations.
    • Financing mechanism: The 15th Finance Commission introduced a new methodology for state-wise allocations, considering factors like past expenditure, risk exposure, hazard, and vulnerability.
    • Utilization: NDRF and SDRF funds are released in two equal instalments, typically with requirements like Utilization Certificates. However, in urgent situations, these requirements can be waived.
    • State Disaster Mitigation Fund (SDMF): This fund supports activities such as forest restoration and public awareness. It received an allocation of Rs 32,030 crore from the 15th Finance Commission.
    • National Disaster Mitigation Fund (NDMF): The NDMF, amounting to Rs 13,693 crore, is dedicated to national disaster mitigation efforts.
