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.
The actual speed is decided by the rate of the memory bus. The speed specified for the memory modules is the maximum speed that they are certified for. There is no performance difference between using memory chips rated at 1200 MHz and 1600 MHz, the difference is that they will fail at different bus speeds.
