An apparatus includes a thermally conductive section with a side facing approximately parallel to an axis and adapted to be thermally coupled to a circuit component, and includes a fluid supply section which directs a fluid flow along the axis toward an opposite side of the thermally conductive section. Furthermore the invention relates to a production cell line obtained by said method, a production method for said protein of interest utilizing said production cell line, and the specific vector carrying the gene of interest itself. This invention provides, in certain embodiments, methods for using a thionin, either alone or in combination with an interleukin, for stimulation of the immune system. The loop response of the PLL can be measured and compared to an ideal loop response. The second camera may include a laser range finder, a scanning laser range finder, an ultrasonic range finder, a device that utilizes auto-focus range finding technology, a binocular camera array, andor a trinocular camera array. The process produces cyclic acetal compounds in high yields.
