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.
Retina HD Displays have a high-definition quality resolution and pixel density of at least 326 pixels per inch, which is sufficiently high enough for the average person to be unable to discern the individual pixels at a normal viewing distance.
