Kani Tribe
- They have a rich traditional knowledge of the medicinal resources in the forests of Agasthyamalai Hills.
- The tribal physicians among them – known as “Plathi” – are the exclusive holders of the traditional medicinal knowledge.
- A formulation named “Jeevani”, which means “giver of life”, was made by a research institute, sourcing ingredients from a plant known called “Arogyapacha” by this tribe.
- A recently discovered arboreal crab – the first of its kind – has been named after this tribe.
- Scientists have discovered a new species of long legged, tree-dwelling crabs in Western Ghats of Kerala. The new species named Kani maranjandu after the Kani tribe in Kerala, are substantially different from other congeners. This is the first report of its kind to offer a record of an arboreal crab — a species that lives in trees.
Barak Missiles
- In News: The Defence Acquisition Council (DAC) of the Defence Ministry on Monday approved the purchase of Barak surface-to-air missiles (SAM) for the Navy among other proposals. Israeli-built Barak short-range SAMs are installed on most of the front-line warships, including the aircraft carrier INS Vikramaditya.
- About DAC: The DAC, set up in 2001 as part of the post-Kargil reforms in defence sector, approves the long-term integrated perspective plan for the forces, accords acceptance of necessity (AON) to begin acquisition proposals, and has to grant its approval to all major deals through all their important phases. It also has the power to approve any deviations in an acquisition, and recommends all big purchases for approval of the Cabinet committee on security.
Bathy Thermograph System
- India is considering procurement of expendable Bathy thermograph systems for the Navy to detect temperature changes under water through the foreign military sales route from the U.S.
- An Expendable Bathythermograph (XBT) is a small probe that is dropped over the side of a ship. As it falls through the water, it measures temperature. Small wires transmit the temperate data back to the ship where it is recorded for further analysis.
- Because the probe falls through the water at a known rate, the depth of the probe can be inferred from the time of launch. Scientists then plot temperature as a function of depth to create a temperature profile of the water.
- It may surprise you to learn that temperature profiles play an important role in multibeam mapping operations. In order to make accurate depth measurements using multibeam sonar, we need to know how fast the sound wave emitted from the sonar unit travels through seawater. The speed at which sound travels changes as the density of water varies through the water column. Temperature and salinity are the two main variables that affect the density of seawater.
- Therefore an Expendable Bathythermograph System helps with making accurate measurements – directly of Temperature throughout the water column, and indirectly of Sound speed profile for the water column and Depth of water and consequently in mapping the seabed.
Right to Vote in India
- In India, the right to vote is provided by the Constitution and the Representation of People’s Act, 1951, subject to certain disqualifications.
- Article 326 of the Constitution guarantees the right to vote to every citizen above the age of 18.
- Further, Section 62 of the Representation of Peoples Act (RoPA), 1951 states that every person who is in the electoral roll of that constituency will be entitled to vote.
- Thus, the Constitution and the RoPA make it clear that every individual above the age of 18, whose name is in the electoral rolls, and does not attract any of the disqualifications under the Act, may cast his vote.
- Therefore voting is both a constitutional and statutory right.
