Congenital hyperinsulinism (HI) is a genetic disorder in which the insulin cells of the pancreas, called beta cells, secrete too much insulin. Excess insulin causes low blood sugar (hypoglycemia). Ordinarily, beta cells secrete just enough insulin to keep the blood sugar in the normal range.
Conduction Insulators, conductors, semiconductors, and superconductors Every material in the world can be defined in terms of how well it conducts electricity. Certain things, such as cold glass, never conduct electricity. They're known as insulators.Materials which do conduct electricity, like copper, are called conductors. In the middle are materials known as semiconductors, which don't conduct as well as conductors, but can carry current.Last, are materials called superconductors, which when brought down to very low temperatures turn into superhighways of current -- they conduct electricity without any resistance whatsoever.hey're known as insulators. Materials which do conduct electricity, like copper, are called conductors. In the middle are materials known as semiconductors, which don't conduct as well as conductors, but can carry current.
The electrolytes in the batteries conduct electricity about one millionth as that of metallic conductors. Non-electrolytes and non-metals conduct electricity less than one-trillionth of that of good conductors in metals. Metals conduct heat and electricity with the help of free electrons in them. When the voltage is applied across the metal, electrons are made to move towards the positive side of the metal. The flow of free electrons will be negligibly resisted and a large flow of electrons takes place.
