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.
This is a big one, and it can really make or break the speed of a CPU. This is something that separates a wimpy microcontroller from a more powerful DSP. Say, for instance, you have a program that requires the extensive use of multiplication and addition, in the form of. y = m*x + b; (This is extremely standard for anything that is linearly calibrated). A cheap microprocessor may only have an ADD instruction, not a MULTIPLY instruction.
