An acid gas scrubbing apparatus and method brings a gas, to be scrubbed, containing carbon dioxide into contact with a gas scrubbing liquid containing alkaline agent and cooled, and acid gases in the gas are removed. A gas scrubber removes acid gases in a gas, to be scrubbed, containing carbon dioxide by bringing the gas to be scrubbed into contact with a gas scrubbing liquid containing alkaline agent. A scrubbing liquid regenerator regenerates and cools the gas scrubbing liquid by bringing the gas scrubbing liquid into contact with a regenerating gas having components different from the gas scrubbing liquid and the gas to be scrubbed. A circulating device is provided between the gas scrubber and the scrubbing liquid regenerator for circulating the scrubbing liquid.

A cooling device for cooling a heat-generating member includes a refrigerant tank for boiling liquid refrigerant by heat from the heat-generating member and a radiator for cooling and condensing gas refrigerant from the refrigerant tank. The refrigerant tank has therein a plurality of refrigerant passages defined by ribs which are integrally formed with any one of opposite wall parts of the refrigerant tank. The ribs continuously extend in an up-down direction to be slightly longer than an up-down dimension of a boiling surface of the refrigerant tank. In the cooling device, because each passage width of the refrigerant passages is set to be equal to or smaller than double Laplace length, an outer diameter of bubbles in the refrigerant passages becomes larger, and liquid refrigerant can be moved upwardly by bubbles. Accordingly, it can restrict liquid refrigerant surface from being lowered even when gas-generating amount is increased.

A method for capturing and reducing the mercury content of an industrial flue gas such as that produced in the combustion of a fossil fuel or solid waste adds a chelating agent, such as ethylenediaminetetraacetic acid (EDTA) or other similar compounds like HEDTA, DTPA and/or NTA, to the flue gas being scrubbed in a wet scrubber used in the industrial process. The chelating agent prevents the reduction of oxidized mercury to elemental mercury, thereby increasing the mercury removal efficiency of the wet scrubber. Exemplary tests on inlet and outlet mercury concentration in an industrial flue gas were performed without and with EDTA addition. Without EDTA, mercury removal totaled 42%. With EDTA, mercury removal increased to 71%. The invention may be readily adapted to known wet scrubber systems and it specifically provides for the removal of unwanted mercury both by supplying S2- ions to convert Hg2+ ions into mercuric sulfide (HgS) and by supplying a chelating agent to sequester other ions, including but not limited to Fe2+ ions, which could otherwise induce the unwanted reduction of Hg2+ to the form, Hg0.

Theinvention performs integrated coordination control by the strip steel flatness and section shape and reduces cold-rolling strip steel lateral thickness difference on the basis of further improving cold-rolling strip steel flatness quality.

A method for locating and installing peripheral drivers has steps of creating a driver profile, creating a resources profile, and of looking to potential driver sources on a prioritized list for drivers that match the driver profile. The driver profile may comprise information such as the peripheral model number, the operating system version number, and the operating system language determined through automated queries. The resources profile generally describes the resources available to the operating system in terms of access to the potential driver sources on the list, and may be used to eliminate sources from the list that are not accessible. The remaining sources on the list are checked in descending priority order until a driver matching the driver profile is found. Once a matching driver is found, it is installed on the operating system.

Techniques are provided for detecting and evaluating ventricular dyssynchrony based on morphological features of the T-wave and for controlling therapy in response thereto. For example, the number of peaks in the T-wave, the area under the peaks, the number of points of inflection, and the slope of the T-wave can be used to detect ventricular dyssynchrony and evaluate its severity. As ventricular dyssynchrony often arises due to heart failure, the degree of dyssynchrony may also be used as a proxy for tracking the progression of heart failure. Pacing therapy is automatically and adaptively adjusted based on the degree of ventricular dyssynchrony so as to reduce the dyssynchrony and thereby improve cardiac function.

A first flash heating is performed in which a lower flash lamp irradiates a back surface of a semiconductor wafer with flashes of light, so that heat conduction from the back surface to a surface of the semiconductor wafer raises the temperature of the surface from the room temperature to an intermediate temperature. Then, a second flash heating is performed in which an upper flash lamp irradiates the surface of the semiconductor wafer with flashes of light, to raise the temperature of the surface of the semiconductor wafer from the intermediate temperature to a target temperature. Since only the irradiation with flashes of light emitted from the lower flash lamp and the upper flash lamp is used to cause the semiconductor wafer having the room temperature to reach the target temperature, all heat treatments can be completed in an extremely short time of one second or less.

A process for accommodating, improving or transmuting random static and dynamic human functions to an object is provided. A device is selected which includes a proximal member and a distal member which articulate relative to one another at an interface. Energy is transmitted through the interface with a predetermined and variable efficacy. The interface is configured to permit static force to have perpendicular and parallel components relative to a primary plane of the interface and to permit a dynamic force to have a parallel component relative to the primary plane. An inertia at the interface is affected in terms of positive or negative affinity between the members and a proximity of the members to one another at the interface such that either the static or dynamic forces attract the members to one another at the interface, such that either the static or dynamic forces attract the members toward one another at the interface urging a contact whereby a tendency for a motion of one member relative to another at the interface is resisted and a tendency for the interface between the members to remain in a statically opposed position is assisted. Alternatively, the static and dynamic forces repel the members from one another at the interface urging a separation whereby a tendency for a motion of one relative to another at the interface is assisted and a tendency for the interface between the members to remain in a statically opposed position is resisted.
