A fluid quick connector sealingly latches first and second components, one of which has a through bore and the other has a raised bead spaced from a tip end. The switching mode power supply apparatus may include a switch unit configured to switch an input voltage to a transformer and a controller configured to select an operation mode having a switching frequency according to a size of a load applied to a secondary side of the transformer and control a switching operation of the switch unit. The extracted information is then entered into an electronic form stored in a data store. Configuration memory cells that store and communicate control signals to the multiplexer transistors are also connected to a low-voltage power supply when the multiplexer is not in use to reduce leakage current through the memory cells. The invention also relates to a peritonitis preventing composition of a lactic acid bacterium that is capable of adhering to the intestine’s mucosa and essentially colonizing it for the preparation of an ingestable carrier. The method comprises the steps of chemical destruction of ammonia with an oxidizing agent, followed by treatment with calcium salts to precipitate insoluble calcium fluoride, and filtration to remove the precipitate.
