Tubal ligation (commonly known as having one's "tubes tied") is a surgical procedure for female sterilization in which the fallopian tubes are permanently blocked, clipped or removed.
A nebulizer is a device that does not use water or heat as other diffusers. [5] The bottle of essential oil is attached directly to the nebulizer. As a result, the unit uses 100% pure essential oil. The benefit of using this device is a strong concentration of the essential oil.
Moist heat sterilization processes sterilize using hot air that is heavily laden with water vapor, which plays the most important role in the sterilization. [ 1 ] [ 2 ] Boiling a sample for 30 minutes or more will kill virtually all vegetative cells present, but will not kill spores , which can germinate shortly thereafter and resume growth.
Tyndallization is a process from the nineteenth century for sterilizing substances, usually food, named after its inventor John Tyndall, that can be used to kill heat-resistant endospores.
Some computer-controlled autoclaves use an F 0 (F-nought) value to control the sterilization cycle. F 0 values are set for the number of minutes of sterilization equivalent to 121 °C (250 °F) at 103 kPa (14.9 psi) above atmospheric pressure for 15 minutes. Since exact temperature control is difficult, the temperature is monitored, and the ...
The proper time and temperature for dry heat sterilization is 160 °C (320 °F) for 2 hours or 170 °C (340 °F) for 1 hour, and in the case of High Velocity Hot Air sterilisers, 190°C (375°F) for 6 to 12 minutes. [3] Items should be dry before sterilization since water will interfere with the process.
Diffuser (sewage), an aerating device for sewage and industrial waste water treatments; Diffuser (thermodynamics), a device that controls the characteristics of a fluid at the entrance to a thermodynamic open system; Aroma lamp (sometimes called an aromatherapy diffuser or reed diffuser), used to disperse essential oils into the surroundings
Specialist companies will often advertise a certain log reduction, e.g., 6-log reduction or 99.9999% effective, instead of sterilization. This takes into consideration a phenomenon known as light and dark repair ( photoreactivation and base excision repair , respectively), in which a cell can repair DNA that has been damaged by UV light.
