摘要： A process for the preparation of 3,4-dihydroxybutanoic acid (1) and salts thereof from a glucose source containing 1,4-linked glucose as a substituent is described. The process uses an alkali metal hdyroxide and hydrogen peroxide to convert the glucose source to (1). The compound (1) is useful as a chemical intermediate to naturally occurring fatty acids and is used to prepare 3,4-dihydroxybutanoic acid-gamma-lactone (2) and furanone (3), particularly stereoisomers of these compounds.

摘要： Processes for removing noxious sulfur oxides from gas streams, particularly from flue gases of coal-burning power plants, using heated layered double hydroxide (LDH) sorbents are described. The sorbent compositions contain metal components, incorporated into the sorbents either by isomorphous replacement of all or part of M.sup.II and/or M.sup.III ions in layers of LDH structures or by impregnation as a metal salt, to promote the oxidation of sulfur dioxide.

摘要： A method and test kit for indirectly assaying for Protein C is described. The method uses tissue thrombomodulin/tissue factor (TTP) and calcium chloride to produce thrombin and activate Protein C to Protein Ca without fibrin formation and then allows time for Protein Ca to inactivate Factors Va and VIIIa. A deficient plasma has a decreased activated thromboplastin assay clotting time compared to a control plasma. The method and test kit is used to diagnose thrombic diseases.

摘要： A coaxial radiofrequency wave plasma generating apparatus with an elongate metallic cavity (10) having a movable elongate coupling probe (16) mounted in line with an axis (a--a) of the cavity having a central coaxial conductor (11) and having a movable plate (12) for obtaining a mode of resonance of the radiofrequency wave in the cavity surrounding a chamber (14) for confining the plasma (100) is described. An end (11b) of the conductor is adjacent to the chamber and can optionally support a set of magnets (27). The apparatus is particularly useful for retrofitting existing vacumm sources (101) having small inlet ports (105) for plasma treatment using molecular beam epitaxy (MBE).

摘要： The present invention is a nonlinear joint transform image correlator which employs a spatial modulator operating in a binary mode at the Fourier plane. The reference and input images are illuminated by a coherent light at the object plane of a Fourier transform lens system. A image detection device, such as a charge coupled device, is disposed at the Fourier plane of this Fourier transform lens system. A thresholding network detects the median intensity level of the imaging cells of the charge coupled device at the Fourier plane and binarizes the Fourier transform interference intensity. The correlation output is formed by an inverse Fourier transform of this binarized Fourier transform interference intensity. In the preferred embodiment this is achieved via a second Fourier transform lens system. This binary data is then applied to spatial light modulator device operating in a binary mode located at the object plane of a second Fourier transform lens system. This binary mode spatial light modulator device is illuminated by coherent light producing the correlation output at the Fourier plane of the second Fourier transform lens system. The inverse Fourier transform may also be formed via a computer. In an alternative embodiment, the Fourier transform interference intensity is thresholded into one of three ranges. An inverse Fourier transform of this trinary Fourier transform interference intensity produces the correlation output.

摘要： A collimator apparatus (10 or 100) including one or more bundles of nested rods (11, 11a or 101 or 101a or 201) which define a surface (112, 112a) which interferes with a beam of radiation is described. The apparatus particularly uses coil spring (48) between and along the axis (a--a or c--c) of the rods which are compressed by blocks (13, 14, 13a and 14a or 103, 104, 103a and 104a) to lock the rods in position in holes in the blocks. The apparatus is particularly useful for shaping radiation beams for patient treatment.

摘要： Method and apparatus are introduced for determining proportional cardiac output (CO), absolute left atrial pressure (LAP), and/or other important hemodynamic variables from a contour of a circulatory pressure waveform or related signal. Certain embodiments of the invention provided herein include the mathematical analysis of a pulmonary artery pressure (PAP) waveform or a right ventricular pressure (RVP) waveform in order to determine beat-to-beat or time-averaged proportional CO, proportional pulmonary vascular resistance (PVR), and/or LAP. The invention permits continuous and automatic monitoring of critical hemodynamic variables with a level of invasiveness suitable for routine clinical application. The invention may be utilized, for example, to continuously monitor critically ill patients with pulmonary artery catheters installed and chronically monitor heart failure patients instrumented with implanted devices for measuring RVP.
