What is inflammation and the steps in the process of inflammation? We often feel redness, heat, swelling and pain at the site of wounds. Actually this is bodyâs defence mechanism to destroy the pathogen. Tissue damage caused by wound or invading pathogenic organisms induces a complex sequence of events collectively known as inflammation.
A flame detector is a sensor designed to detect and respond to the presence of a flame or fire. Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.
The only electromagnetic radiation that Humans can truly see unaided is visible light (the colors in the rainbow). Humans can sense Infrared light with their skin, and â¦ they can sort of sense X-rays, Gamma rays, and UV light if you count getting cancer, radiation sickness, or a sunburn sensing.     Humans can see radiation over the entire spectrum with instrumental aids such as IR cameras and Spectrum Analysers.
