Nuclear Reactors

 Nuclear reactors A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a self-sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas), … Read more Nuclear Reactors

Molecules

 Molecules Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance. The division of a sample of a substance into progressively smaller parts produces no change in either its composition or its chemical properties … Read more Molecules

Microbiology

 Microbiology Microbiology is the study of microbes or the living organisms that are too small to be visible with the naked eye. These living things can be seen only with the use of a microscope. These life forms are called microorganisms or microbes. Microorganisms include bacteria, archaea, viruses, protozoa, microscopic fungi and yeasts, … Read more Microbiology

Total Internal Reflection

 Total internal reflection Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle. In general, total … Read more Total Internal Reflection

Important Organic Compounds

 Some Important Organic Compounds   The chemical compounds of living things are known as organic compounds because of their association with organisms and because they are carbon-containing compounds. Organic compounds, which are the compounds associated with life processes, are the subject matter of organic chemistry. Among the numerous types of organic compounds, four major categories … Read more Important Organic Compounds

General Studies Of Alternating Current And Direct Current

 General studies of alternating current and direct current Alternating Current Alternating Current (AC) Alternating current describes the flow of charge that changes direction periodically. As a result, the voltage level also reverses along with the current. AC is used to deliver power to houses, office buildings, etc. AC can be produced using a … Read more General Studies Of Alternating Current And Direct Current

Respiratory Quotien1

 Respiratory quotient: Carbohydrates, fats and protein The respiratory quotient (or RQ or respiratory coefficient), is a dimensionless number used in calculations of basal metabolic rate (BMR) when estimated from carbon dioxide production. It is calculated from the ratio of carbon dioxide produced by the body to oxygen consumed by the body. Such measurements, … Read more Respiratory Quotien1
