To ensure maximum performance of the battery cells powering the electric motor driving the G7e torpedo (that is achiving speed of 30 knots at distance 5000 m for T-II and T-III torpedo and running distance of 7500 m for T-IIIa torpedo), shortly before the launch the cells were heated up to a temperature 30 Â°C.
A quarantine is used to separate and restrict the movement of persons; it is a 'state of enforced isolation'. This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease.
As the name implies this method of quarantine involves isolating in a rat free environment at either a separate location from the colony or in an area where there is a totally separate air supply. This is the safest method of quarantine for a fancier or non-laboratory colony.
