Features of Octacopter The drone is made of lightweight carbon fibre with a foldable structure for ease of transportation. It has unique features like autonomous guidance through dual redundant MEMS-based digital autopilot with advanced flight instrumentation systems. It can fly …
Radiocarbon Dating: Radiocarbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. Method: The basis of radiocarbon dating is simple: all living things absorb carbon from the atmosphere and food sources around them, including a certain amount of natural, radioactive carbon-14. …
Ultraviolet(UV) Light: Ultraviolet(UV) is a type of light or radiation naturally emitted by the Sun. It covers a wavelength range of 100-400 nm. The human visible light ranges from 380 to 700 nm. Types of UV light: There are three types of UV radiation that are classified according to their wavelength: UV-A (315-400 nm): It has a long …
Cryptogam: A cryptogam is a plant or a plant-like organism that reproduces by spores without flowers or seeds. The term Cryptogamae means “hidden reproduction”, referring to the fact that no seed is produced. Thus, cryptogams represent the non-seed-bearing plants. Cryptogamic plants include Algae, mosses, liverworts, lichens, ferns, and fungi Why in news? India’s first cryptogamic garden housing nearly …
Methanogens: Methanogens are methane generating microorganisms which are capable of generating methane as a metabolic by product. They do not require oxygen to live and are widely distributed in nature. They are found in swamps, dead organic matter, and even in the human gut. Also, they are known to survive in high temperatures, and simulation studies have …
Triboelectric Nanogenerator(TENG)? A triboelectric nanogenerator(TENG) is a self-powered device. It makes use of mechanical energy in the form of vibrations, which is present everywhere in different forms to generate electricity. Working: It works on the principle of creation of electrostatic charges via instantaneous physical contact of two dissimilar materials. It is followed by generation of potential difference when a mismatch …

LiDAR (Light Detection and Ranging) is a remote sensing method that uses light in the form of a pulsed laser to measure ranges & variable distances. These light pulses combined with other data recorded by the airborne system generate precise, three-dimensional information about the shape of the Earth and its surface characteristics. LiDAR instrument principally …

Project Seabird: Project Seabird is the largest naval infrastructure project at Karwar, Karnataka. The project involves creation of a naval base at Karwar on the west coast of India. Upon completion, the project will provide the Indian Navy with its largest naval base on the west coast and also the largest naval base east of the Suez Canal. Navy’s lone aircraft …
Overture Supersonic Aircraft: These are futuristic supersonic aircrafts. These aircrafts are planned to be open for passengers by 2029. Supersonic aircraft are planes that can fly faster than the speed of sound. Usually, supersonic planes can travel at the speed of around 900 kmph, twice the speed of normal aircraft. Concorde, the British-French turbojet-powered commercial airliner, was …
Bnei Menashe, son of Manasseh, represents an ethnolinguistic group from North East India with members from Chin, Luchai, Kuki and Mizo Tribes. They are settled in Manipur and Mizoram and considered to have descent from Manasseh, one of the 10 original Jews Tribes which were exiled from the Land of Israel. Since 2003, a number …
