A liner for a shaped charge having a composition comprising greater than 90% by weight of powdered tungsten and up to 10% by weight of powered binder, the composition being formed into a substantially conically shaped body and having a crystal structure of substantially equi-axed grains with a grain size of between 25 nano-meters and 1 micron. The crystalline quality is inspected by using a visible light source to irradiate the surface of the poly Si and examining the variations of the reflected light caused by the protrusion arrangement at the surface of the poly Si. The process of esterification may be carried out by reacting cinnamic acid with aliphatic mono hydric alcohol in presence of catalyst, removing the catalyst by conventional methods. This circuit configuration saves the level shifting on the microprocessor side, and realizes a high-speed access to the semiconductor memory from the microprocessor. In another embodiment, the system, sensor and technique characterizes andor evaluates the performance of the optical lithographic equipment, for example, the optical sub-system of such equipment. The matching method determines one or more advocates by maximizing the estimated contextual value of personalized advocacy.
