silver star

To cum on someone's back in the outline of a star.
Came from the infamous tattoo that many women get on their lower backs.

Guy: I just made a silver star.
Girl 1: Aw it looks so good.
Girl 2: I wish I had a silver star.
Guy: Coming right up.

Silverback

a creature/(not entirely sure) with silver skin on the back of the neck that wears baby blue shorts in the middle of winter. It has a crazy foot tapping ability at a frequency of 1500 meters. Its mating call for the Ugma is muscle spasms in all four limbs and a yawn.

The Silverback is picking the silver off its elbows and replacing its cuticles with lead.

Fractional Volume of an extraction solvent

Fractional Volume of an extraction solvent is a fraction of the optimum volume of the extraction solvent obtained by dividing the optimum volume of the extraction solvent needed to extract all of the desired solute from a given mass of the solid material into equal smaller volumes for use in separate extraction cycles

If 100ml of an extraction solvent is the optimum volume that would extract all the herbal solute from a medicinal herb, then 100ml/2 gives a fractional volume of an extraction solvent of 50ml, 100ml/3 gives a fraxtional volume of an extraction solvent of 33.333ml

100ml/4 gives a fraxtional volume of an extraction solvent of 25ml,
1/5 x 100 ml gives a fraxtional volume of an extraction solvent of 20ml.

Using fractional volumes of an extraction solvent for extraction purposes gives better extraction yields than using the optimum volume of an extraction solvent as a whole.

silverlink

Very slow train. Takes longer than the megabus, but costs more! Also slang term for skiving or driving too slowly.

Croft, why are you doing 60 on the motorway? Are you the silverlink?
