The caffeine is removed from green coffee beans, before they are roasted, and there are a number of different processes, all of which affect the roasting process and how long the coffee stays fresh. (Decaf coffee goes stale almost twice as fast as regular coffee.) The first decaffeination method, developed in the early 1900s, used a repetitive rinsing process aided by the chemical benzene, which is no longer used because it is a known cancer-causing agent.
Retina Display is a marketing term developed by Apple to refer to devices and monitors that have a resolution and pixel density so high â roughly 300 or more pixels per inch â that a person is unable to discern the individual pixels at a normal viewing distance.
The retina is a thin layer of tissue that lines the back of the eye on the inside. It is located near the optic nerve. The purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition.The retina processes light through a layer of photoreceptor cells.These are essentially light-sensitive cells, responsible for detecting qualities such as color and light-intensity. The retina processes the information gathered by the photoreceptor cells and sends this information to the brain via the optic nerve.he purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition.
