An apparatus for allocating entries in a set associative cache memory includes an array that provides a first pseudo-least-recently-used vector in response to a first allocation request from a first functional unit. The valve rod, the adjusting tube and the moveable tube are coaxially arranged in a telescopic manner. In certain embodiments, the olefin esters are formed by reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters, separating the olefins from the esters in the metathesized product, and transesterifying the esters in the presence of an alcohol to form a transesterified product having olefin esters. If the list contains too many items to be displayed on one card, the list module divides them into groups nearly equal in size, so that to display any one item requires the same or nearly the same number of cards.
