A sheet processing apparatus includes a binding portion binding a plurality of sheets stacked on a sheet stacking portion as a bundle by deforming the sheets without a staple. The authentication control section is provided with a time setting section that stores a set time length in memory, a timer that measures time, and a time decision section that determines lapse of the set time length in accordance with the time length stored in the memory section and the time measured by the timer. The impingement baffle is configured to guide a heat exchanger fluid from the shell fluid inlet to distribute the heat exchanger fluid uniformly around the tubes. The method further comprises determining, with the controller, a height of the saddle block, determining, with the controller, a saddle gap radius, and determining, with the controller, a saddle block shimming gap by comparing the saddle gap radius with the height of the handle. More particularly, the invention relates to systems, devices, and related methods that sequester leukocytes andor platelets and then inhibit their inflammatory action. The circuit board includes resistive heating elements for heating electrical components in the circuit to limit the formation of frost and condensation on the components.
