Working Principle: Passengers or cargo are loaded on the Hyperloop vehicle that accelerates gradually via electric Propulsion through a low pressure tube. Its Vehicles are propelled using a linear electric motor, which is a straightened out version of a conventional rotary motor. The speed of conventional trains — and all land based transport — is … Read more

When there are changes in the condition like temperature, light or nutrients the symbiotic linkage between algae and zooxanthellae gets deteriorated, causing them to turn white. In coral bleaching the density of zooxanthellae decline and the concentration of photosynthetic pigment decline which lead to decline in color. 20% of the coral reefs have already been … Read more

Thermoelectric power generators are the devices which used to convert temperature difference between two junctions into electrical energy. A working of thermoelectric generator is based on Seebeck effect.  According to which, a loop of two dissimilar metal develops an emf when the two junctions are kept at different temperature. That is why it is also referred as Seebeck … Read more

The SSLV is being designed by Indian scientists to carry smaller commercial satellites into the low-earth orbit less than 2,000 km above the earth’s surface. The SSLV can launch dedicated payloads or multiple satellites into low earth orbit or sun-synchronous orbit. The payload will be 300 kg to sun synchronous orbit (SSO) and 500 kg … Read more

Genetic recombination is the process by which two DNA molecules exchange genetic information, resulting in the production of a new combination of alleles. In eukaryotes, genetic recombination during meiosis can lead to a novel set of genetic information that can be passed on to progeny. Most recombination is naturally occurring. During meiosis in eukaryotes, genetic … Read more

TYPES OF MISSILE AND ASSOCIATED CONCEPTS: Brahmos Supersonic cruise missile, BrahMos, is being developed with Russia as a private joint-venture. BrahMos is a multi-platform cruise missile enabling it to strike from various types of land, sea and air-based platforms. It is among the fastest supersonic cruise missiles in the world with speeds ranging between Mach … Read more

The GSLV-III or Geosynchronous Satellite Launch Vehicle Mark III is a launch vehicle under development. Geosynchronous Satellite Launch Vehicle is a launch vehicle under development. ISRO is developing this to enable India to launch its heavier satellites without dependence on foreign rockets and providers. The GSLV MK-III is a 3 stage vehicle and will have … Read more

On March 27, DRDO conducted Mission Shakti, an anti-satellite missile test, from Dr APJ Abdul Kalam Island launch complex. One of India’s existing satellites operating in lower orbit used in the mission. The test was successful on all parameters. India has made it clear that its space capabilities aren’t directed against anyone and the government … Read more

Stem cells are a group of cells in our bodies, with capacity to self-renew and differentiate to various types of cells, thus to construct tissues and organs. In science, it is still a challenge to understand how a fertilized egg to develop germ layers and various types of cells, which further develop to multiple tissues … Read more
