A closed circuit system was designed to apply ultrasound during the elaboration of the lipid intravenous emulsions (LIEs).
The amine system was designed as a closed circuit system with the primary objective of removing H2S, CO2, and other acidic components from liquid and gaseous hydrocarbon streams.
The fully automated, computer controlled, sterile, closed circuit system enables physiologic pulsatile perfusion and negative pressure ventilation, while gas exchange function, and metabolism can be evaluated.
Two cooling systems were designed and operated successfully: firstly an open circuit using cold gaseous helium from a storage vessel, but also a closed circuit system based on a cryogenerator.
The investigation can be applied by setting closed circuit system next to the rectifier with Ampere meter placed series to the circuit as shown in Fig. 9a. Figure 9b shows the charging current to the battery measured using the Ampere meter.
We used a closed circuit system to recycle the gases in combination with a hollow fiber module as an interface between the gases and the liquid phase for safety reasons due to the explosive character of the gas mixture and due to the necessity of enabling elevated gas transfer conditions under those simplified cultivation conditions.
My work is very simple in a technological way, involving the relationship of the video projection to a live camera in a closed circuit system in the live performance.
Kidneys from Sprague-Dawley rats were perfused for 180 min with constant perfusion pressures (80 mmHg (n = 4); 120 mmHg (n = 4)) in a closed circuit system.
In the device evaluated in this report, liquid is contained in a closed circuit system, avoiding the risks and potential complications of instilling free liquid into the gastrointestinal system.
Some common physical security countermeasures are—electronic burglary systems, closed circuit television (CCTV) systems, electronic access control systems, perimeter security systems, locks, lighting, fire systems, and specialized protection systems.
Equipment suppliers and the consultants who meld security devices into multimillion-dollar systems say airports may also install improved versions of other types of security products, including such widely used equipment as closed circuit television systems and X-ray machines.
