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.
Core is the graphics processor, memory is what communicates with the graphics processor to output to the screen. Both affect performance. Core: This is the graphics processor (GPU). Think of it as a CPU that processes what you see on your screen. The core speed (measured in megahertz) is the clock speed that the GPU runs at. There's much more to GPU performance than just its clock speed, but if I tried to explain this, I'd just confuse the hell out of you.
