This is known as CRISPR cas 9 , a Genetic editing tool ,short for Clustered Regularly ... Read more

Medium of Propagation

Medium of Propagation Sound is a sequence of waves of pressure which propagates through compressible media such as air or water. During their propagation, waves can be reflected, refracted, or attentuated by the medium. The purpose of this experiment is to examine what effect the characteristics of the medium have on sound. Ground Wave or Surface Wave Propagation A ground wave travels along the surface of the earth. These waves are vertically polarized. So, vertical antennas are useful for these waves. If a horizontally polarized wave is propagated as a ground wave, due to the conductivity of the earth, the ... Read more

Artificial intelligence

Artificial intelligence Artificial intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions. The term may also be applied to any machine that exhibits traits associated with a human mind such as learning and problem-solving. Artificial intelligence is based on the principle that human intelligence can be defined in a way that a machine can easily mimic it and execute tasks, from the most simple to those that are even more complex. The goals of artificial intelligence include learning, reasoning, and perception. As technology advances, previous benchmarks that ... Read more

Chemistry in daily life

Chemistry in daily life The principles of chemistry have been used for the benefit of mankind. Think of cleanliness  the materials like soaps, detergents, household bleaches, tooth pastes, etc. will come to our mind. Look towards the beautiful clothes, immediately chemicals of the synthetic fibres used for making clothes and chemicals giving colours to them will come to our mind. Chemistry and food Chemicals are essential building blocks for everything in the world. All living matter, including people, animals and plants, consists of chemicals. All food is made up of chemical substances. Chemicals in food are largely harmless and often ... Read more

Health and Hygiene

Health and Hygiene Maintaining personal hygiene is essential for more than one reason; social, health, personal, psychological or just as a way of life. Maintaining a good standard of hygiene helps keep infections, illnesses and bad odors at bay. The importance of hygiene should be taught from an early age to help cultivate good habits. Personal hygiene can be defined as an act of maintaining cleanliness and grooming of the external body. Maintaining good personal hygiene consists of bathing, washing your hands, brushing teeth and sporting clean clothing. Additionally, it is also about making safe and hygienic decisions when you ...

Health awareness Programme

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 society. History of healthcare campaigns that brought down rates of epidemics, communicable diseases by spreading nail hitting messages. Campaigns that let people know of diseases that people weren’t known to before, awareness campaigns that give out powerful messages on prevention and cure of a certain ... Read more

Heat: Measuring Temperature, Thermometers, Transformation of Heat

Heat: Measuring Temperature, Thermometers, Transformation of Heat Heat, energy that is transferred from one body to another as the result of a difference in temperature. If two bodies at different temperatures are brought together, energy is transferred—i.e., heat flows—from the hotter body to the colder. The effect of this transfer of energy usually, but not always, is an increase in the temperature of the colder body and a decrease in the temperature of the hotter body. Measuring Temperature The measurement of temperature is a comparatively new concept. Early scientists understood the difference between “hot” and “cold,” but they had no ... Read more

Indian Space Research Organization (ISRO)

Indian Space Research Organization (ISRO) Indian Space Research Organisation (ISRO), was founded in 1969 to develop an independent Indian space program. Its headquarters are in Bangalore. ISRO’s chief executive is a chairman, who is also chairman of the Indian government’s Space Commission and the secretary of the Department of Space. The Indian Space Research Organisation (ISRO) operates through a countrywide network of centres. Sensors and payloads are developed at the Space Applications Centre in Ahmedabad. Satellites are designed, developed, assembled, and tested at the U R Rao Satellite Centre (formerly the ISRO Satellite Centre) in Bangalore. Launch vehicles are developed ... Read more

Periodic Table  and periodicity

Periodic Table  and periodicity Criteria for a new element discovery Assessing if an element has been “discovered” is not a simple task. While reviewing the discovery profiles of the transfermium elements in the early 90s’, IUPAC and IUPAP set up to establish a series of criteria that must be satisfied for the discovery of an element to be recognized. Temporary name and symbol While an element can have been claimed, before the claim has been validated and before the element is formally named, the element has a temporary name and symbol.   Validation and assignation of an element discovery Claims ...

Preparation and properties of commonly used dyes

Preparation and properties of commonly used dyes Dye, substance used to impart colour to textiles, paper, leather, and other materials such that the colouring is not readily altered by washing, heat, light, or other factors to which the material is likely to be exposed. Dyes differ from pigments, which are finely ground solids dispersed in a liquid, such as paint or ink, or blended with other materials. Most dyes are organic compounds (i.e., they contain carbon), whereas pigments may be inorganic compounds (i.e., they do not contain carbon) or organic compounds. Pigments generally give brighter colours and may be dyes ... Read more
