摘要:
A method for sterilizing fruits and vegetables includes irradiating a surface of fruits and vegetables with UVA, while the surface of the fruits and vegetables is in contact with chlorine water containing sodium hypochlorite having a chlorine concentration of 5 ppm or more. According to the method for sterilizing fruits and vegetables, the fruits and vegetables can be quite efficiently sterilized by chlorine water having a quite low concentration, that is 5 ppm or more, slightly higher than that of tap water. Further, multiplication of bacteria in the sterilized fruits and vegetables can be effectively prevented, while a residual chlorine concentration in the sterilized fruits and vegetables is significantly reduced.

An object of invention is to display necessary information on a screen and display predicted information obtained by predicting the progression of the necessary information. In a bed-side information system, a body information monitor 11 measures arterial blood pressures of a patient 14. The body information monitor 11 measures systolic arterial blood pressures and diastolic arterial blood pressures, and calculates average values thereof. A Hematocrit monitor 12 calculates Hematocrit, change blood volume rate, and Venous Blood Oxygen Saturation. The body information monitor 11 transmits arterial blood pressure information to a desktop PC 15 and the Hematocrit monitor 12 transmits Hematocrit, change blood volume rate, and Venous Blood Oxygen Saturation to the desktop PC 15. The desktop PC 15 displays arterial blood pressure, Hematocrit, change blood volume rate, and Plasma Refilling Rate on a screen of a display using these information items.
摘要:
Bacteria in water 9 exposed outdoors are effectively killed with ultraviolet (UV) light by suppressing post-treatment increase in the bacteria population due to photoreactivation. The apparatus shines UV light on the water 9 to kill bacteria and has UV light emitting diodes (LEDs) 1 that emit UVA light with a primary emission peak of 320 nm-400 nm. The antibacterial action of the UVA light emitted by the UV LEDs 1 prevents proliferation of bacteria in the disinfected water 9 due to photoreactivation.

A method is provided for detecting filter clogging which are able to keep track of the filter clogging with precision and in detail. At least one pressure selected from the group consisting of a pressure Pa in a blood inflow portion (32a), a pressure Pv in a blood outflow portion (32b), a pressure Pf1 in a filtrate inflow portion (32c), and a pressure Pf2 in a filtrate outflow portion (32d) is measured continuously, then a variation (pressure waveform) of the pressure is analyzed, a clogging of a filter (32) is detected using the analyzed result. Thereby a clogging of a filter is detected early. As a result, it is possible to prevent from developing of the filter clogging by controlling a dosage amount of anti-coagulant properly and changing a flow rate of blood. The variation of the pressure wave may be analyzed by subjecting the variable to Fast Fourier Transform.
