  1. The ornamental design for a shelf, as shown and described.

FIG. 1 is a top perspective view of the shelf;

FIG. 2 is a front view of the shelf;

FIG. 3 is a top view of the shelf;

FIG. 4 is a side view of the shelf;

FIG. 5 is a bottom view of the shelf;

FIG. 6 is a rear view of the shelf;

FIG. 7 is a side perspective view of the shelf; and,

FIG. 8 is a front perspective view of the shelf.

The main objective of the shelf is to allow both small and heavy loads to be placed on both sides of the shelf without influence on airflow inside the testing equipment. It includes a shelf with an obdurate steel wire frame and a stainless steel plate with holes. The holes promote free air flow inside the testing equipment. The shelf has a parallel runner so that it will not be dumped when the user pulls or pushes the shelf for adjusting the experimental loads.
