The lethality of pulsed ultra-violet (UV) rich light for the inactivation of pathogenic bacteria has been investigated. A low pressure xenon filled flash lamps that produced UV intensities have been used. The pulsed operation of the system enable the release of electrical energy stored in the capacitor into the flash lamp within a short time and produces the high current and high peak... https://wxbmqm2qx7v9.blog2freedom.com/34914805/the-development-of-a-secure-internet-protocol-ip-network-based-on-asterisk-private-branch-exchange-pbx
