   QUICK REVISION ( ARTICLE:3, SCIENCE): TYPE OF NUCLEAR REACTORS   COMPONENTS OF NUCLEAR REACTOR:   Fuel: Usually pellets of uranium oxide (UO2) arranged in tubes to form fuel rods. The rods are arranged into fuel assemblies in the reactor core   • Moderator: This is material which slows down the neutrons released … Read more Type Of Nuclear Reactors

 Determinants of Nuclear Tests: Pokhran I (1974) and Pokhran II (1998) Pokhran 1 test The emergence of China as fifth nuclear power in October 1964 constituted a significant threat to India’s territorial integrity and sovereignty. The strained relations between the two countries after the 1962 aggression sparked off an acrimonious debate on defence … Read more Determinants Of Nuclear Tests

 Biopesticides Plants, growing in the wild or in cultivation, face numerous threats from insects, bacteria, viruses, and fungi, as well as from other plants. Biopesticides are inert substances or living organisms that can help protect plants from such threats. Chemical pesticides can offer similar protection but, by contrast, are neither alive nor made … Read more Biopesticides

 Flood and Drought Occurrence Drought Drought is a complex, slow-onset phenomenon of ecological challenge that affects people more than any other natural hazards by causing serious economic, social and environmental losses in both developing and developed countries. The period of unusual dryness (i.e. drought) is a normal feature of the climate and weather … Read more Flood And Drought Occurance

 Factors affecting photosynthesis There are three main factors affecting photosynthesis and several corollary factors. The three main are:   Light irradiance and wavelength Carbon dioxide concentration Temperature. Total photosynthesis is limited by a range of environmental factors. These include the amount of light available, the amount of leaf area a plant has to … Read more Factors Affecting Photosynthesis

 Linear motion Linear motion, also called uniform motion or rectilinear motion, motion in one spatial dimension.  According to Newton’s first law (also known as the principle of inertia), a body with no net force acting on it will either remain at rest or continue to move with uniform speed in a straight line, … Read more Linear Motio1

 Properties and applications of petroleum products Gases Gaseous refinery products include hydrogen, fuel gas, ethane, propane, and butane. Most of the hydrogen is consumed in refinery desulfurization facilities, which remove hydrogen sulfide from the gas stream and then separate that compound into elemental hydrogen and sulfur; small quantities of the hydrogen may be … Read more Properties And Applications Of Petroleum Products

 Electricity and its effects -electric intensity, potential, potential difference Electricity is the physical flow of electrons, referred to as an electrical current. Electricity is an energy carrier that efficiently delivers the energy found in primary sources to end users, who in turn convert it into energy services. Electricity can be created in three … Read more Electricity And Its Effect1
