ISRO successfully conducts test of Vikas Engine for Gaganyaan Program

Source: AIR What is the News? Indian Space Research Organisation(ISRO) has successfully conducted the third long-duration hot test of the liquid propellant Vikas engine for the Gaganyaan programme. About Vikas Engine: Vikas is a family of liquid fuelled rocket engines conceptualized and designed by the Liquid Propulsion Systems Centre(LPSC) in the 1970s. LPSC is a… Continue reading ISRO successfully conducts test of Vikas Engine for Gaganyaan Program

Blockchain technology

Blockchain is a shared structure, having immutable ledger for recording transactions, tracking assets and building trust through several databases, known as chains, in a network connected through peer-to-peer nodes.   Option 1 is correct. All network participants in the blockchain have access to the distributed ledger and its immutable record of transactions. As it is a shared ledger,… Continue reading Blockchain technology

Visible light communication (VLC) can be used for large data transfers

Visible light communication (VLC) is a wireless method that enables high-speed transmission of data with visible light. This data is transmitted by modulating the intensity of light given off by a LEDs. The signal is received by a photodiode device that transforms the data into forms that are readable and readily-consumed by end users.  Statement 1 is… Continue reading Visible light communication (VLC) can be used for large data transfers

Potential of Artificial Intelligence(AI)

Artificial intelligence has the potential to cut energy waste, lower energy costs, and facilitate and accelerate the use of clean renewable energy sources in power grids worldwide. It can also improve the planning, operation, and control of power systems through Smart Grid.  Machine learning is an application of artificial intelligence (AI) that provides systems with the ability to automatically learn… Continue reading Potential of Artificial Intelligence(AI)

Pronuclear Transfer can be used for Prevention of mitochondrial diseases in offspring

Pronucleus is the nucleus of a sperm or an egg cell during the process of fertilization. The sperm cell becomes a pronucleus only after the sperm enters the ovum, but before the fusion of genetic material of the sperm and egg.  The technique of pronuclear transfer involves the transfer of pronuclei from one zygote to another. Under… Continue reading Pronuclear Transfer can be used for Prevention of mitochondrial diseases in offspring

Pneumococcal Conjugate Vaccines are effective against pneumonia

Pneumococcal Conjugate Vaccines are effective against pneumonia as well as meningitis and sepsis.  Pneumococcal disease refers to any illness caused by pneumococcal bacteria. These bacteria can cause many types of illnesses, including pneumonia, meningitis, blood infections, and Sepsis. Dependence on antibiotics that are not effective against drug-resistant bacteria can be reduced. Pathogen gets lesser time to evolve with vaccination… Continue reading Pneumococcal Conjugate Vaccines are effective against pneumonia

Applications of drones

In aviation and in space, a drone, also called an “unmanned aerial vehicle,” or UAV, refers to an unpiloted aircraft or spacecraft. To reduce weight and increase manoeuvrability, a typical unmanned aircraft is made of light composite material allowing military drones to cruise at extremely high altitudes. UAVs are controlled by remote ground control systems… Continue reading Applications of drones

Plant Vs Animal cells

Both plant and animal cells are eukaryotic i.e. they contain a nucleus and organelles, and are enclosed by a plasma membrane. Protozoa, fungi, plants and animals have Eukaryotic cells. Plant cells are unique among eukaryotic cells for several reasons. For maintenance of structural support, plants have reinforced, relatively thick cell walls that are made mostly of… Continue reading Plant Vs Animal cells

Benzene Pollution

Benzene Pollution is a colourless or light-yellow chemical that is liquid at room temperature. It has a sweet odour and is highly flammable. Benzene is formed from both natural processes and human activities.   Natural sources of benzene include volcanoes and forest fires. Benzene is also a natural part of crude oil, gasoline, and cigarette smoke. Normal environmental concentrations of benzene are unlikely to damage… Continue reading Benzene Pollution

Carbon nanotubes (CNTs) as carriers of drugs and artificial blood capillaries

Carbon nanotubes (CNTs) Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene). They can be single-walled (SWCNT) with a diameter measured to less than 1 nanometer (nm). They are very lightweight, almost 1/6th of the steel with a mechanical tensile strength of almost 400 times that of steel.… Continue reading Carbon nanotubes (CNTs) as carriers of drugs and artificial blood capillaries
