A
long-lived transaction is a transaction that spans multiple database transactions. The transaction is considered "
long-lived" because

long-lived radioisotope of iodine which occurs naturally, but also is of special interest in the monitoring and

long-lived plant and fungal species, no individual part of a clonal colony is alive (in the sense of active metabolism ) for
Kaynak: List of long-living organismsIt is the most significant
long-lived fission product of uranium fission, with a half-life over 2000 times as long as the next longest-
Kaynak: Technetium-99The most popular among scientists are
long-lived 237 Np (t½ 2.20 6 years) and short-
lived 239 Np, 238 Np (t½ ~ 2 days). Sixteen isotopes of

Kaynak: Neutron poisonhas a very low boiling point. Technetium , the main
long-lived fission product , is also efficiently converted to its volatile hexafluoride.

long-lived bird that is cyclically regenerated or reborn.
