Now it is Chacon, the picture of confident calm in his loose-fitting pants and wide-brimmed cap, masterfully mixing speeds and pitching a lot like El Duque.

"He mixes speeds so well, he just keeps guys off balance."

Other considerations-like time, temperature, concentration, mixing speeds and even the chemical ingredients themselves-that do not come up when making very small amounts of a material arise when attempting to make vastly larger volumes for commercial testing and mass market production.

While showing an array of pitches and not being prone to walks, she relied on a fastball, curveball and changeup combination, mixing speeds in her curve sparingly, with an impeccable control over location.

The bandwidth advantages, the improved isolation of devices from each other, the ability to easily mix different speeds of devices and the elimination of the chaining limits inherent in non-switched Ethernet have made switched Ethernet the dominant network technology.
