    摘要: A hydrated granular carrier is prepared for microbe immobilization in a biological treatment apparatus such as for treating waste water and exhaust gas. The carrier contains hydrated granular gel particles coated with a finely ground organic powder. The gel particles are made of a polymer insoluble in cold water but soluble in hot water. In making the hydrated gel particles, heated water is added to the polymer while stirring at high speed. Then, the finely ground organic powder is added together with heated water while stirring at high speed to coat the finely ground organic powder on the gel particles. Preferably, the polymer is polyvinyl alcohol having a degree of polymerization of 1000 to 2500 and a degree of saponification of 98% or more. Heated water added to the polyvinyl alcohol is added by spraying at 10 to 15 liters per minute at a temperature of 40.degree. to 100.degree. C. in an amount of 50 to 150 parts by weight based on 100 parts by weight of the polyvinyl alcohol. The organic powder is activated charcoal having a particle size of 200 mesh or less in an amount of 3 parts by weight or more, and the water added with the charcoal is at 40 to 100.degree. C. in an amount of 5 to 20 parts by weight. The high speed stirring is at 500 to 1000 rpm.

    摘要: A diagnostic system comprises: a spectral imaging means that captures a spectral image within a predetermined wavelength range in a body cavity and obtains spectral image data; an image processing means that receives the spectral image data, determines an index value indicating a region that is highly likely to be a lesion from the spectral image data, and generates and outputs an extracted lesion image based on the index value; and a monitor on which the extracted lesion image is displayed. The image processing means performs multiple regression analysis for each pixel of the spectral image with the spectral image data as a dependent variable and respective light absorption properties of oxyhemoglobin and deoxyhemoglobin as independent variables, and determines the index value based on respective concentrations of the oxyhemoglobin and the deoxyhemoglobin.
