What is a Bladder Infection? A bladder infection is also known as cystitis, and is commonly referred to as a urinary tract infection (UTI). When bacteria enters the urinary tract via the urethra, sometimes it moves up into the bladder, where it can multiply and cause an infection. Although generally very uncomfortable, treating a bladder infection is not difficult. Most bladder infections or UTIâs are caused by the bacterium Escherichia coli (E.coli).
Sicilian Defense The Sicilian Defense is the most popular defense against whiteâs opening 1.e4 and is used extensively at top level play.

They also used explosives to demolish underwater obstacles planted by the enemy. As the U.S. Navy's elite combat swimmers, they were employed to breach the cables and nets protecting enemy harbors, plant limpet mines on enemy ships, and locate and mark mines for clearing by minesweepers.aval Demolition Units landed as part of the Allied invasion of Sicily; they were divided in three groups that landed on the beaches near Licata, Gela and Scoglitti. In 1943, the Navy decided to create a large dedicated force for such tasks: the Naval Combat Demolition Units (NCDU).
