This breakthrough innovation offers an outstanding opening and closing pressure allowing for the quickest release of C[O.sub.2] and the most efficient preservation of roasted coffee.
In nine modern high performance presses, they are pressed in steel moulds with a closing pressure of up to 400 tonnes.
This measured pressure, expected to be equal to the tissue pressures, was the closing pressure (PC).
A lumbar puncture revealed an opening pressure of 46 and closing pressure of 15 cm [H.sub.2]O , a protein of 82, and glucose of 54 mg/dL with leukocytosis of 390 cells/[micro]L and 17% eosinophils.
The opening pressure of cerebrospinal fluid (CSF) was 380 mm[H.sub.2]O and closing pressure was 180 mm[H.sub.2]O.
The opening pressure was greater than 35 cm [H.sub.2]O and the closing pressure was 20.5 cm [H.sub.2]O.
It has an electric screw drive and clamp movements, but the closing pressure buildup is servo-hydraulic.
Acute abdominal compression in patients with OSA might be associated with increased UA closing pressure.[sup][7]
If the pressure generated by the suture is greater than the closing pressure of the skin capillaries, the result will be local necrosis.
The chamber is connected to the nitrogen reservoir equipped with a pressure gauge and it is placed in a hot compression moulding press that ensures the heating of the chamber and its good closing for perfect control of the gas pressure that must be lower than the press closing pressure. A pump was used to create vacuum in the treatment chamber before injection of the gas.
However, proper sealing of Lyoseal caps requires more force; therefore, as an option, Klee equips its freeze dryers with a hydraulic system that builds up 15% more closing pressure. This ensures that sufficient force can be applied, including additional reserve.
