A polymeric, surgical clip having first and second curved leg members joined at their proximal end by a hinge portion and movable from an open position to a closed position for clamping a vessel between curved deposing inner surfaces which are substantially parallel when the clip is closed. This invention allows each node of the wireless sensor network to move in random directions in a three dimensional space. This results in the generation and transmission of an MTU error message back to the initiating node. Also provided are a process for preparing such supported catalysts, as well as methods for hydrotreating, hydrodenitrogenation, andor hydro desulfurization, using supported catalysts. The leadframe housing may be folded along the hinge such that the broadside of the first contact is positioned along the broadside of the second contact. When the electric heater is connected to the control, the identifying resistor provides information with regard to the capacity of the particular electric heater that is being attached to the control.
