Vitamins

A vitamin is an organic compound and a vital nutrient that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet; thus, the term vitamin is conditional upon[…]

Protected: Taxidermy Workshop 2002

Taxidermy is the art of preservation of living creatures by preparing and stuffing the skin of animals, birds and fishes to maintain their external looks or features and to inhibit bacterial action on them by using chemical substances. The person who will do the practices of taxidermy is called taxidermist. Wolf is a wild, flesh-eating animal of the dog family that will hunt in packs. Often found in some places in our country. One of the interesting things about wolfs, that they sleep with open eyes. Preservation of animals and birds in a life like form are such an interesting part of biology science.

Ion Selective Electrode

ISE:

Its transducer or sensor that measures activity of specific ion dissolve in a solution into an electrical potential formed across “the membrane”

This potential can be measured by either voltmeter or pH meter

Voltage (mV) α Log (ionic activity) ; as per “Nernst Equation”

Voltage depends on: (species used, concentration, temperature and pressure)

Normal Distribution Curve

In probability theory, the normal (or Gaussian) distribution is a very common continuous probability distribution. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. The normal distribution is useful because of the central limit theorem. In its most[…]
