Various medical devices (such as catheters and guide wires) need hydrophilic coatings to reduce friction for maneuvering through blood vessels. They did so by studying hydrophilic, lipophilic, free-soluble and insoluble-bound phenolic extracts, using a lipoxygenase/4-nitroso-N,N-dimethylaniline (LOX/RNO) technique.
The clock rate typically refers to the frequency at which a chip like a CPU(central processing unit), one core of a multi-core processor, is running and is used as an indicator of the processor's speed. It is measured in the SI unit hertz.
Processor speed (otherwise known as clock speed) is related but not at all the same as processor power. There are many potential differences between processors that have the same GHz rating. These may or may not make a noticeable difference or might make an extreme difference depending on the type of task your computer is used for. For example: Floating point co-processor; Multiple cores; Multiple threads; Virtualisation extensions
