Abstract: An organic-waste-processing apparatus reducing a moisture of, and conducting a thermal operation process to, an organic waste, includes: a moisture-reducing unit; a combustion unit; a combustion-energy-supply unit; an energy-supply-operation controller; an organic-waste-energy-estimating unit; a total-energy-consumption measuring unit; a relation-maintaining unit; a quantitative-relationship-grasping unit; and a moisture reduction controller. The moisture reduction controller controls an operation of the moisture-reducing unit so that the estimated value of the organic waste energy to be estimated by the organic-waste-energy-estimating unit is directed in a direction reducing a quantitative difference from the optimum value of the organic waste energy based on the quantitative relationship grasped by the quantitative-relationship-grasping unit between the optimum value of the organic waste energy and the latest estimated value of the organic waste energy.

Abstract: A sample containing hemoglobin A1c (HbA1c) is simultaneously brought in contact with a solid phase and anti-HbA1c antibody, the anti-HbA1c antibody bound to the adsorbed HbA1c on the solid phase and the anti-HbA1c antibody in solution are separated, and the anti-HbA1c antibody bound to the adsorbed HbA1c on the solid phase is detected. HbA1c % is determined by one-step immunoassay, and the time required for measurement is shortened in comparison with conventional immunoassay methods. Since the exposure time to the pretreatment solution present in the reaction solution during the immune reaction is shortened, formation of a precipitate in the sample as well as inactivation of the enzyme of the enzyme-labeled anti-HbA1c antibody, when used, is reduced.
