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.
Human and rat retinas have two types of light receptors: cones are sensitive to bright light and color, and rods are sensitive to dim light and cannot see color. Human and rat retinas differ, however, in the types and density of cones in the retina, which has implications for color vision.
