in situ Chem., Med.
Derived from Latin, meaning confined to the place of origin. In chemistry it means production of a chemical species within the reaction mixture. In medicine, it means a cancer that is confined to
the point of origin and has not spread.
in vitro Biol.
A technique of performing an experiment in a laboratory, controlled environment that is outside a living organisms or cells. The results may not always correspond to the real biological system. Ther term
is derived from Greek, meaning in the glass.
incandesence Chem.
Emitting brilliant visible light as the temperature of a substance is raised. For instance, burning of magnesium metal in air, emitting brilliant white light.
indefinite integral Math.
If F(x) and g(x) are two functions of x, then F(x) is said to be an indefinite integral of g(x) if F(x) exists:
The function g(x) is called an integrand, is said to be integrable. Usually an arbitrary constant, c, is included with the indefinite integral when integrating the above equation,
that is, F(x) + c.
inert gas Chem.
One of the element that is grouped at the extreme right of the periodic table of the elements (helium, neon, argon, krypton, xenon and radon). They have a complete outer (valence) electrons
and thus unreactive (inert) to most of the chemical reactions. However, heavier elements such as xenon forms a few unstable compound, especially with fluorine. Inert gases are also known
as rare gases or noble gases.
infrared Phys.
Region of the electromagnetic spectrum located just outside visible light, corresponding to a light of a slightly longer wavelength than red light, in a range of 10-7m to
10-5m. Our body gives out heat in the form of infrared radiation which cannot be detected with our eyes but can be detected with a suitable equipment such as night goggles.
Invar Eng.
A tradename for a nickel-steel alloy of iron (63-64%), nickel (36%) and with other substances in trace quantities such as cobalt, carbon and manganese. It has a very low expansion over a restricted temperature
range and is used in watches and other instruments to reduce their sensitivity to changes in temperature. It was invented in 1896 by Swiss-French scientist C.É. Guillaume (1861-1938).
