A good one, well cared-for, can last for many years.Irish pipers often must master the art of reed making, as well as reed adjustment and maintenance. Trust me, this is no simple task. In conclusion, each of the traditions of bagpiping is replete with a body of repetoire, technique and playing opportunities. Of late, there have been more and more interchanges between the two, as it is quite possible to set Irish melodies on the Scottish chanter, and visa-versa. Bagpipers occupy a somewhat rarified world, inhabited by devotees and connoisseurs, as well as practitioners.
noun, plural: half-lives. (1) Biological half-life, i.e. the period in which the amount of substance inside the living organism is metabolized and eliminated half of its initial amount by normal biological process.
Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy. Dormancy tends to be closely associated with environmental conditions.ormancy is not relevant for viruses as they are not metabolically active themselves. Some viruses are physically stable and may remain infectious for long periods of time, such as poxviruses and picornaviruses. Some viruses may infect cells and then remain inactive for some time, for example Herpesviruses.
