On newer routers, buffers have become large enough to hold several seconds of buffered data. Different implementations of channels may be buffered or not, and either synchronous or asynchronous. Cases can be wrapped with alkaline or buffered tissue paper. The lactic acid produced is buffered by minerals in the shell, preventing acidosis. Most shampoos are buffered so that they are slightly acidic. Keyboard interrupts typically cause keystrokes to be buffered so as to implement typeahead. Messages were buffered at the nodes adjacent to the sending and receiving terminals. These solutions are often referred to as buffered or balanced crystalloids. "Legionella" is traditionally detected by culture on buffered charcoal yeast extract agar. Modified release preparations are buffered and absorption is not affected. This RAM is where the bitmap of image data is "buffered" for display. Each inter frame can reference up to three of the buffered frames for temporal prediction. These effects can, however, be temporarily buffered by external motivations and beliefs in unlimited willpower. This refers to an implementation of stencil buffered shadow volume algorithms. Some researchers argued that the messages are buffered in the "ether" or the "environment".
