Fiber optics, or optical fibers, are long, thin strands of carefully drawn glass about the diameter of a human hair. These strands are arranged in bundles called optical cables. We rely on them to transmit light signals over long distances. At the transmitting source, the light signals are encoded with data… the same data you see … Read more DMPQ- What is Optical fibre technology? How do optical fibre works?

Navigation satellite is a system which provides system of artificial satellite that helps in providing autonomous geospatial positioning. It helps to provide positioning information regarding local time to high precision. Global positioning system launched(GPS) by NASA is an example of it. India Launched Indian regional navigation satellite system called IRNSS. It is a constellation of … Read more What is navigation satellite? India launched IRNSS recently, what is IRNSS? What are its application?

The Earth BioGenome Project, a Moon Shot for biology, aims to sequence, catalogue and characterize the genomes of all of Earth’s eukaryotic biodiversity over a period of ten years. The Earth BioGenome Project will create a new foundation for biology, informing a broad range of major issues facing humanity, such as the impact of climate … Read more DMPQ- What is EarthBiogenome Project?

3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.  The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can … Read more DMPQ- What is 3D printing ? Explain the need of the government policy for 3D printing.

Application of radioactivity: • Health: 1. Found extensive use in diagnosis and therapy eg. Phosphorous-32 is used to identify the cancerous cell. As cancer cell absorb more phosphorous, Iodine 131 is employ to determine cardiac output, plasma volume and fat metabolism and particularly to measure the activity of thyroid gland. 2. To treat cancer cells: … Read more DMPQ- List out the main Application of radioactivity.

Biodynamics a holistic, ecological, and ethical approach to farming, gardening, food, and nutrition. Biodynamics is rooted to integrate scientific understanding with a recognition of spirit in nature. Around the world, biodynamics is alive in thousands of thriving gardens, farms, vineyards, ranches, and orchards. The principles and practices of biodynamics can be applied anywhere food is … Read more DMPQ:What is bio dynamics? Explain its role in sustainable development and assuring farmers income. (Science)

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 percent of the earth’s potable water. An excess of fluoride … Read more DMPQ- Explain the method of Defluoridation for water purification.

Molecular farming is a new technology that uses plants to produce large quantities ofpharmaceutical substances such as vaccines and antibodies. It relies on the same method used to produce genetically modified (GM) crops – the artificial introduction of genes intoplants.A number of vaccines, antibodies and other therapeutic substances made in plants such as      tobacco, maize, … Read more DMPQ: Write short note on Molecular farming?
