    摘要： The present invention reliably computes cardiac output with a noninvasive procedure. The system measures the electrical impedance of a patient's body, during a time interval of interest. The system then obtains frequency transforms of various time segments of the first derivative of the impedance signal. Each such transform is integrated over a frequency range of interest, and the values of the integrals are plotted as a function of time. The graph so derived has characteristic extrema which can be used to identify critical points in the impedance derivative signal. These critical points can be used to determine parameters which are used in a calculation of stroke volume and cardiac output.

    摘要： Enhanced removal and/or control of adhesives or sticky materials, “stickies”, from recovered paper stock or virgin pulp fibers is achieved using a combination of enzyme treatment with adsorbents and/or absorbents. Pulp stock to be treated is typically obtained from old magazines, newspapers, household waste, but may include corrugated boxes and office waste. Virgin pulps may include mechanical, chemical, or semi-chemical pulps. Enzymes typically include hydrolases such as cellulases, hemicellulases, pectinases, amylases, and lipases such as esterases, lyases such as pectate lyases, and oxidoreductases. Adsorbents include activated bentonite, microparticles, talc, clay and modified silica. Absorbents typically include water soluble polymers, dispersants, coagulatants and agglomerants.
