Methods The esophageal and bronchial lumens of 449 patients undergoing elective pulmonary and esophageal operations, the air of operating rooms and the hands of operating personnel were bacteriological analyzed.
Conclusions: The air of grade-3 clean operating rooms is heavily contaminated by bacteria in the course of operation. Activity and number of operating staff are the main factors influencing the change in concentration of descending bacteria.
A soundproof electromagnetic screen that protects the operating personnel and provides for the normal operation of electronic devices is described.
Increasing stress of the grid as well as changed and unpredictable system states caused by the restructuring of the power industry raise the demand on expressive but condensed display of the current system situation for the operating personnel.
This control strategy can be expected to be accepted by the operating personnel in wastewater treatment plants.
Review your design criteria with operating personnel, get their input.
The radiation level of the equipment and services of the steam condensation channel does not hinder repair work or lead to overexposure of the operating personnel.
