Msthods Thirty blood specimens were taken with separate gel and without gel. 14 items of biochendcal tests were made comparatively afer having been stored at room temperature for l. 2.6 and 8 hours respectively.
7 operation room were 24 cfu/m 3 after it had been used 10 months. This datum was amounting to the standard of biological clean grade Ⅱ in our country (as the Grades Ten Thousand Purification Standard) and going beyond the Biological Purification Grades Ten Thousand of NASA.
Reasons for microbial contamination on object surface were found by taking samples from floor, wall, operating table and instruments these representive sections, and measures were given to prevent microbial contamination in different parts in the room.
Results There were obvious differences in antisepsis and sterilization effects between different departments: the operating room had the highest qualification rate of 94.4%; the qualification rate neonatal intensive care unit(NICU) and ICU was related to number of people;
CONCLUSIONS Ducted cooled air plus fan coil units and split room air conditioning can be used safely. Ventilation system in isolation units can produce negative pressure effectively when some special requests achieved.
To explore the regulation and detection of circumstance status i n clean operation area and running room, present some advice in the fields such as temperature , humidity, pressure gradient, clear degree of the room and daily attendance of equipments include floor.
The interaction between 18-methyl norethindrone and ketoprofen, including the displacement of ketoprofen from human serum albumin binding sites, was investigated by the capillary electrophoresis-frontal analysis method (CE-FA) at room temperature.
The crystal energy of ionic liquid is much lower than ionic solid and this is the underlying reason for forming ionic liquid at room temperature.
The reaction process was monitored by the temporal evolution of the UV-Vis absorption and room temperature photoluminensce spectra.
The samples were characterized by XRD, BET, DTA-TG, UV-Vis, and their photocatalytic properties were evaluated with two model pollutants, methylene blue (MB) and rhodamine B (RB), at room temperature.
The P-E hysteresis loops are measured by means of the Sawyer-Tower test system with a compensation resistor at room temperature.
