Genome A genome is the DNA, or sequence of genes, in a cell. Most of the DNA is in the nucleus and intricately coiled into a structure called the chromosome. The rest is in the mitochondria, the cell’s powerhouse, and some is chloroplast DNA. Every human cell contains a pair of chromosomes, each of which has three billion base pairs or one of four molecules – … [Read more...]
Nuclear Magnetic Resonance & Magnetic Resonance Imaging
Nuclear Magnetic Resonance (NMR) Nuclear Magnetic Resonance is an analytical chemistry technique used in quality control & research. Nuclear Magnetic Resonance (NMR) can determine the content at the molecular level. NMR spectroscopy is the study of molecules by recording the interaction of radiofrequency (Rf) electromagnetic radiations with the nuclei of … [Read more...]
Lithium-ion battery, Internal Combustion Engine vs. Electric Vehicles
IIT Madras researchers have fabricated a rechargeable iron ion battery. With the increased focus on electric vehicles, it is essential to develop rechargeable batteries that are cheaper. With no lithium reserves in India, the stress is on developing rechargeable batteries of comparable performance using materials other than lithium. John B Goodenough, M Stanley … [Read more...]
Precision Farming, Geoinformatics for Precision Farming
India’s agriculture is focused on production which isn’t necessarily translating into productivity & profitability. Shrinking land, depleting water and other related resources in agriculture are a serious cause of concern. Hence, there is a need for promoting farmer friendly location specific production systems to achieve vertical growth in agriculture with judicious … [Read more...]
Ballistic Missile vs. Cruise Missile, India’s Missile Systems, IGMDP
We frequently notice news related to ballistic missiles, cruise missiles and various missile systems of India. Memorizing names and salient features of various Indian missiles is hard without having a broader understanding of the concept of ballistic missiles and cruise missiles, and major missile defence systems. It is better to give these concepts a holistic structure rather … [Read more...]
Kepler’s laws, Satellite Orbits, Launch Vehicles PSLV & GSLV
The terms like Kepler’s laws, satellite orbits, geosynchronous orbit, geostationary orbit, polar orbit, PSLV, GSLV, etc. keep on appearing in the news columns whenever there is a satellite launch. So I thought it is better to keep all the related concepts in one place. Kepler's laws of planetary motion (applicable to satellites also) Kepler’s First Law: The orbit of … [Read more...]
