 Electric transformers Electrical transformers are machines that transfer electricity from one circuit to another with changing voltage level but no frequency change. Today, they are designed to use AC supply, which means that fluctuation in supply voltage is impacted by the fluctuation in the current. So, an increase in current will bring about … Read more

 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

 Civilian and military uses of Nuclear energy Civilian uses Plant mutation breeding Plant mutation breeding is the process of exposing the seeds or cuttings of a given plant to radiation, such as gamma rays, to cause mutations. The irradiated material is then cultivated to generate a plantlet. Plantlets are selected and multiplied if … Read more

Yet, over one third of income is spent towards food and related consumption and hence, social security support for health, education, housing etc. becomes critical. However, over half a century post-independence, there … Read more

 Electric current Ohm’s law and Resistance   Electrical current is the flow of charged particles. The flow of charges will be constant in current electricity. Electric current flows from higher electric potential to lower electric potential. For the current to flow, it requires a circuit which is closed loop of a conducting material. … Read more

 Circulatory System v  The circulatory system can be compared to a system of interconnected, one-way roads that range from superhighways to back alleys. v  Like a network of roads, the job of the circulatory system is to allow the transport of materials from one place to another. v  As described in Figure below, … Read more

 Remote sensing- GIS and its application   Remote Sensing Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation. In current usage, the term “remote sensing” generally refers to the use of satellite- or aircraft-based sensor technologies … Read more

Health awareness Programme Health Awareness Campaigns are one of the most functional elements in health system that push people to create that big change to eradicate or lessen the unhealthy impact the health issue. Healthcare Awareness Campaigns are meat to trigger that action of change, promise a healthier society with long standing impact in the … Read more

 Biotechnology in environmental clean up process Landfill Technologies Solid wastes account for an increasing proportion of the waste generated by urban societies. While a part of this volume consists of glass, plastics, and other non-biodegradable material, a considerable proportion of this is made of decomposable solid organic material, like food wastes from large … Read more
