Abstract: A process for reducing mercury emissions through a low-level addition of a halogen to a mercury-containing feed material, such as coal, in which the halogen is added prior to combustion. Combustion of the mercury-containing feed material having the added halogen produces a gas stream containing a vapor-phase halogen that is generated from the added halogen, and vapor-phase elemental mercury. The mercury-containing gas stream is brought into contact with a reactive surface agent, and the vapor-phase halogen converts the vapor-phase elemental mercury into an ionic mercury. The ionic mercury is collected by the reactive surface agent for removal thereof from the mercury-containing gas stream.

Abstract: Systems and methods for monitoring current state of spatially extensive supply network having at least one control station that monitors and controls the supply network and sensors that transmit measurement values of operating behavior to the control station. Current measurement values are measured at positions on the supply network corresponding to each sensor. Each sensor analyzes measured signal variations and trends of the measured current values via an evaluating unit. The measurement values of each sensor are transmitted to the control station in data packets at a defined time. At each sensor, when the analysis detects an abnormal measurement signal variation, frequency of transmission of the respective sensor and each adjacent sensor increases, the respective sensor transmitting the measurement values to the control station or to adjacent sensors to which the respective sensor is connected through a common supply line and which measure an identical or physically similar quantity.

Abstract: Embodiments of the present invention provide systems and methods for the treatment of pain through activation of select neural fibers. The neural fibers may comprise one or more afferent neural fibers and/or one or more efferent neural fibers. If afferent fibers are stimulated, alone or in combination with efferent fibers, a therapeutically effective amount of electrical stimulation is applied to activate afferent pathways in a manner approximating natural afferent activity. The afferent fibers may be associated with primary receptors of muscle spindles, golgi tendon organs, secondary receptors of muscle spindles, joint receptors, touch receptors, and other types of mechanoreceptors and/or proprioceptors. If efferent fibers are stimulated, alone or in combination with afferent fibers, a therapeutically effective amount of electrical stimulation is applied to activate intrafusal and/or extrafusal muscle fibers, which results in an indirect activation of afferent fibers associated therewith.
