  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 from fission so … Read more

 Harmful bacteria Pathogenic Bacteria These bacteria cause great losses to plant and animal popula­tion by causing several diseases. Reduction of Soil Fertility Some facul­tative anaerobic bacteria are available mostly in the oxygen deficient soil which reverse the nitrifying process, thereby causing the loss of a part of its combined nitrogen. They break down the … Read more

 When it comes to working with electrical equipment, putting safety precautions in place for any electrical project is always a top priority. From basic knowledge and equipment safety to personal precautions and equipment performance, knowing what to do to help prevent injuries and ensure safety can be a lifesaver. Avoid Water   A critical … Read more

 Pros of Nuclear Energy Low Pollution: Nuclear power also has a lot fewer greenhouse emissions. It has been determined that the amount of greenhouse gases have decreased by almost half because of the prevalence in the utilization of nuclear power. Nuclear energy has the least effect on nature since it doesn’t discharge any gasses … Read more

 , Construction working, uses, ray diagram Simple telescope A simple working telescope requires nothing more than a pair of lenses mounted in a tube. The lens in front, known as the objective, focuses an image; the lens in back, known as the eyepiece, magnifies the image. Although it may seem like a crude device, … Read more

 When a DC current passes through a long straight conductor a magnetising force, H and a static magnetic field, B is developed around it If the wire is then wound into a coil, the magnetic field is greatly intensified producing a static magnetic field around itself forming the shape of a bar magnet giving … Read more

It is a science of cultivation of Garden plants. The word Horticulture in derived from the Latin word Hortus meaning enclosure (garden) and culture – meaning, … Read more

QUICK REVISION: NANOTECH AND ITS APPLICATION   Definition:Nanoscience and Nanotechnology involves the concept of manipulating the extremely small things at nanoscale. At nanoscale things behave differently and this properties can be utilised across various fields of science like chemistry, biology, medicine, physics and material science.   APPLICATION OF NANO ON HEALTH SECTOR: Repairing of damaged … Read more

 Generator is a machine that converts mechanical energy into electrical energy. It works based on principle of faraday law of electromagnetic induction. The faradays law states that whenever a conductor is placed in a varying magnetic field, EMF is induced and this induced EMF is equal to the rate of change of flux linkages. … Read more

 Vector borne diseases Main vectors and diseases they transmit Vectors are living organisms that can transmit infectious diseases between humans or from animals to humans. Many of these vectors are bloodsucking insects, which ingest disease-producing microorganisms during a blood meal from an infected host (human or animal) and later inject it into a new … Read more
