Abstract: A method for screening a sample containing phenol, isopropylated phosphate (3:1), the method includes: steps 3 and 4 of acquiring a content of a compound group or a value corresponding to the content as a measured value for each of a plurality of compound groups among a compound group in which the total number of isopropyl groups that three phenyl groups of triphenyl phosphate have as substituents is 1, a compound group in which the total number is 2, and a compound group in which the total number is 3; and steps 5 and 6 of determining that the sample contains phenol, isopropylated phosphate (3:1) based on a result of comparing the measured value with a threshold determined previously for the compound group corresponding to the measured value.

Abstract: A computer assisted system and method for acquisition and processing of medical history, includes facilitating, by a processor, receipt of medical history data corresponding to a patient in a structured format. The history data includes information corresponding to health condition of the patient. The method includes providing a quick response code corresponding to the medical history data of the patient to a physician system. Further, the method includes facilitating, by the processor, receipt of physician observation data from the physician system in response to the quick response code. The physician observation data is appended to the medical history data. The method includes transforming, by the processor, the medical history data of the patient and the physician observation data into a natural language format. Furthermore, the method includes storing, by the processor, the medical history data of the patient in the natural language format in an electronic medical record.

Abstract: A modified push-pull booster circuit is proposed, wherein two alternately switching transistors are disposed on the primary winding of a transformer, and a bridge rectifier and a charging circuit are disposed on the secondary winding; wherein the bridge rectifier has a pair of inductors with inductive coupling installed on the first half and second half of the circuit. The push-pull circuit uses series inductance to step up the bus voltage, and, because of the degaussing effect when current is induced on the inductors, the inductance of the inductor can be decreased even without using snubber circuit, thus decreasing the peak voltage of the bridge rectifier, and balancing the magnitude of current flow in the secondary winding. By reducing the turn ratio on the transformer windings, the operating efficiency of the booster circuit can be considerably improved.
