A high performance thermoelectric system is taught which is capable of rapidly cooling a thermal load with a thermoelectric module. Prior to entering each chamber, the contaminated aqueous phase is mixed with a stream containing gas bubbles to aid in flocculation and flotation of the immiscible phase contaminant. Further, deletion factor points associated with deletion factors corresponding to the extracted attribute information sets are extracted from the point database for each content item, and evaluation points are calculated in accordance with the extracted plural deletion factor points. The zoom lens system is substantially telecentric toward the reduction side. In creating the first cache, information may be included configured to define a hierarchy of the first item. Each opening has a ring for rigidly anchoring to a downstream member of the hinge, and each opening has a ring acting as a rigid receiver.
