Abstract: 2-phenyliminothiazolines of the following formula I, their salts, their preparation method and their use for treating rice blast. The phenyliminothiazolines and their salts of the present invention have low toxicity to environment or living organisms, and exert high activity at low concentration for treating rice blast through a new controlling mechanism, that is by inhibiting pentaketide synthesis and cyclization of the melanin sythesis process in formula I.

Abstract: A method for determining the core flow rate from pump differential pressure method equations and a heat balance equation for determining the temperature and density of the reactor water in the downcomer and lower plenum region. The measured reactor water temperature is used only as an initial estimate for this new method. This allows the first estimate of the core flow to be determined based upon the reactor water density that corresponds to this temperature and the pump differential pressure and pump rotational speed measurements. Then, with this intial core flow measurement value, and other available plant measurements and assumed nominal values for the heat balance equation, revised values for the reactor water temperature and density can be calculated. Using a standard numerical method, such as the successive approximation technique, a more accurate estimate for the reactor water density can be obtained.
