A system and method is described for managing data objects in a fixed-content storage system. The method comprises: enabling pixel elements from an array of selectable pixel elements; in response to enabling the pixel elements, gating a light; sequentially exposing adjacent areas of a semiconductor film, such as Si, to the gated light; annealing the light-exposed areas of semiconductor film; and, in response to the annealing, laterally growing crystal grains in the semiconductor film. The cover defines at least one opening for receiving an input tube therethrough such that raw materials, reagents, gases and products can be introduced into or removed from the test tube. These corner stones are the product of the method and are laid on the corner formed by the right angle joint between the walls, giving the illusion of a thick building stone wall with nearly the low cost and easy laying of thin stone. The object is then inserted into a row of a distributed database using the row name. At least one of a thermal conductance and a heat transfer rate between the two thermally and electrically conductive bodies is determined based at least on the mutual capacitance measurement.
