About Tetanus:

• Tetanus, also known as lockjaw, is a serious bacterial infection that affects the body's nervous system.
• It's caused by a poison (toxin) made by the bacterium Clostridium tetani (C. tetani).
• The bacterium usually enters the body through an open wound.
• Tetanus bacteria live in soil and manure. They can also be found in the human intestine and other places.
• Tetanus occurs more often in warmer climates or during the warmer months.
• It’s not spread from person to person.
• Anyone can get tetanus, but the disease is particularly common and serious in newborn babies and pregnant women who have not been sufficiently immunized with tetanus-toxoid-containing vaccines.
• Treatment:
  • There's no cure for tetanus.
  • Treatment focuses on managing symptoms and complications until the effects of the tetanus toxin resolve.
  • People who recover from tetanus do not have natural immunity and can be infected again.
• Prevention:
  • Tetanus is completely preventable by being immunized (vaccinated).
  • Immunization usually protects against tetanus infection for 10 years.
  • The childhood schedule includes five doses, followed by boosters in adolescence and every 10 years.
  • Pregnant women are also advised to receive Tdap to protect their newborns.

About Zardalu Mangoes:

• Zardalu mango, also called Jardalu, is a unique mango variety from Bhagalpur, Bihar.
• It is known for its light yellow skin and distinct special aroma.
• Its story dates back to the early 19th century when Maharaja Rahmat Ali Khan Bahadur of Haveli Kharagpur introduced its cultivation in the Bhagalpur region.
• The first sapling, planted between 1810 and 1820, still stands in Tagepur village, serving as a living testament to this mango's enduring legacy.
• The Jardaloo mangoes are available from mid-April through the end of June.
• The fruits have a rich, creamy, tender texture, and delicate, non-fibrous, juicy pulp.
• As the fruit matures, the skin of the Zardalu mango turns golden-yellow with a tinge of red across the top of the fruit.

About Giant’s Causeway:

• It is located on the coastal edge of the Antrim Plateau in Northern Ireland.
• The region consists of 6 kilometers (4 miles) of stepping-stone-like black basalt columns.
• Each stone is a curiously distinct polygon or hexagon, with seemingly unnatural straight edges.
• The pillars range in height, and shoot up out of the sea, increasing in height until they reach the cliff top.
• This stepping stone or stair-like appearance of the area is where the Giant’s Causeway name is thought to have originated, as the columns look much like steps for a giant.
• It was declared a UNESCO World Heritage Site in 1986.
• Formation:
  • The rock and column formations were first formed some 50 to 60 million years ago, during the Paleogene Period.
  • The columns originally formed due to extensive volcanic activity in the area.
  • Molten basalt rose up through a layer of chalk beds, creating what is known as a volcanic plateau.
  • The lava then began to cool and contract, which caused fractures and edges within the rock.
  • As the lava flow continued to cool, it receded, leaving behind tall column shapes.
  • Because the lava cooled very quickly, it receded a great deal, leaving behind particularly prominent and large columns.

About Indrayani River:

• It is located in Maharashtra.
• It is a tributary of the Bhima River (a tributary of the Krishna River).
• Course:
  • It is a rain-fed river that originates from the Western Ghats, near the hill station of Lonavala, located along the Mumbai-Pune Highway.

  • It follows a course mostly north of the city of Pune.
• The river has great religious importance, and the two sacred towns, Alandi and Dehu, are situated on its banks.
  • Dehu is known to be a sacred place for being the hometown of the poet Saint Tukaram, who was a popular saint of Maharashtra, and Alandi holds the samadhi of the poet Dnyaneshwar.
• The Indrayani also passes through the industrial town of Pimpri-Chinchwad and plays a role in irrigation and local agriculture.

About  Arbitrage Funds:

• Arbitrage funds are equity-oriented hybrid funds that leverage arbitrage opportunities in the market.
• The basic principle behind arbitrage is to take advantage of temporary price differences to generate profits with minimal risk.
• These can be a pricing mismatch between two exchanges, different pricing in the spot and futures market,
• The fund manager of an arbitrage fund buys and sells the shares at the same time and earns the difference between the selling price and the buying price of the share.
• The underlying principle is to capture the price spread between the buying and selling, often within a short time frame.
• This is fundamentally different from any other form of investing, where you purchase an asset and wait for it to grow in value before selling it.
• In an arbitrage fund, the fund manager invests in equities only when he finds a definite opportunity to earn returns.
• If there are no arbitrage opportunities available, then the fund invests in short-term money market instruments and debt securities to ensure stable returns.
• The important thing to note here is that the price difference is usually very small. Therefore, the fund manager has to make several trades in one day to book a reasonable profit.
• They are classified as hybrid mutual funds where according to the Securities and Exchange Board of India (SEBI), at least 65% of the fund’s assets must be in equities and equity-related securities.
• Benefits:
  • Low Risk, Equity-Like Returns: Since the buying and selling are hedged, the risk is minimal, making it an attractive option for risk-averse investors.
  • Tax Advantages: Gains from arbitrage funds held for more than one year qualify as long-term capital gains (LTCG).
  • Liquidity: Arbitrage funds offer high liquidity, allowing investors to redeem their money quickly when needed.
  • Diversified Portfolio: These funds diversify investments across various sectors and instruments, reducing the risk.
• Limitations:
  • Market Dependency: Returns are linked to market volatility; low volatility means fewer opportunities for arbitrage.
  • Short-Term Focus: They may not be ideal for long-term wealth creation.

About Arbuscular Mycorrhizal Fungi:

• These are groups of root obligate biotrophs belonging to the phylum Glomeromycota.
• These are soil-borne microorganisms form symbiotic associations with approximately with 80% of terrestrial vascular plants.
• Structure: These are made up of tiny branching threads called hyphae.
• These hyphal networks form two-way pipes to channel nutrients and carbon to and from plants.
• Grassland ecosystems like those in South Sudan, the Tibetan plateau, and India’s Banni grasslands house 40% of the world’s AM fungal networks.
• It networks also weigh around 300 million tonnes of carbon, which is four- to six-times the weight of the entire human population.
• Ecological Role:
  • They are considered natural biofertilizers which provide the host with water, nutrients, and pathogen protection.
  • They provide nutrients and water in exchange for the carbon produced by the plants, and helps to regulate the climate by drawing carbon into soils.
  • It formed symbiotic relationships with 70% of plant species, trading nutrients for carbon and sequesters an estimated 4 billion tonnes of CO2-equivalent a year.
