Disclosed is a catalytic pipe for an endothermic catalytic reaction of a process medium, with an outer cladding tube which is tightly closed at its end sides by a first base and a second base. A first electrical power supply connection can be connected to a mains supply network. The use of exogenous activators of one or the other according to the needs of a particular system is readily accomplished. The digital camera performs operations on the image data of the first and second images stored at specified locations in the virtual memory space, and while performing those operations allocates and de-allocates memory pages in the physical memory space to virtual memory pages in the virtual memory space and updates the page table accordingly.
