 Working principle and use of generator   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 … Read more Generator

 Food bio technology Biotechnology is defined in accordance with the Convention on Biological Diversity, i.e. “any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use” Biotechnology as applied to food processing in most developing countries makes use of microbial inoculants to … Read more Food Bio Technology

 Engineering plastics Engineering plastics are a group of plastic materials that have better mechanical and/or thermal properties than the more widely used commodity plastics (such as polystyrene, PVC, polypropylene and polyethylene).  Being more expensive, engineering plastics are produced in lower quantities and tend to be used for smaller objects or low-volume applications (such … Read more Engineering Plastics

 Impact of Solid Waste; Recycling and Reuse HEALTH AND ENVIRONMENTAL EFFECTS An effective solid waste management system is necessary to avoid public health disasters, spread of disease by insects and vectors and adverse effect on water and air. Solid waste workers are the most exposed to the risks of parasitic infections and accidents, … Read more Impact Of Solid Waste; Recycling And Reuse

 Concept of pressure Pressure is the perpendicular force per unit area, or the stress at a point within a confined fluid. The pressure exerted on a floor by a 42-pound box the bottom of which has an area of 84 square inches is equal to the force divided by the area over which … Read more Concept Of Pressure

 Usefulness of animals and human affairs As food The human population exploits a large number of animal species for food, both of domesticated livestock species in animal husbandry and, mainly at sea, by hunting wild species.  Marine fish of many species, such as herring, cod, tuna, mackerel and anchovy, are caught commercially, forming … Read more Usefulness Of Animals And Human Affairs

 Defluoridation and other Techniques of water purification Defluoridation Defluoridation is the downward adjustment of the level of fluoride in drinking water. Worldwide, fluoride is one of the most abundant anions present in groundwater. Fluoride is more present in groundwater than surface water mainly due to the leaching of minerals. Groundwater accounts for 98 … Read more Defluoridation And Other Techniques Of Water Purification

 Microscope Microscope, instrument that produces enlarged images of small objects, allowing the observer an exceedingly close view of minute structures at a scale convenient for examination and analysis. Although optical microscopes are the subject of this article, an image may also be enlarged by many other wave forms, including acoustic, X-ray, or electron … Read more Microscope
