Often the gills are enclosed in protective chambers, and ventilation is provided by specialized appendages that create the respiratory current.
The dosimeters were set in a protective cylindrical PVC tube chambers, each chamber having 9 cm diameter and 7 cm height (area A = 6.36 × 10−3 m2, volume V = 4.45 × 1−4 m3).
In contrast to the Ge case, where an engineered interface layer greatly improves electrical characteristics, we show that ALD-Al2O3 deposited on the In0.53Ga0.47As (1 0 0) − 4 × 2 surface after in situ thermal desorption in the ALD chamber of a protective As cap results in an atomically-abrupt and unpinned interface.
Transfer samples, phosphatase assay buffer, substrate in a radioisotope-protective rack into the anaerobic chamber Add 0.02> ml samples containing 30 μg proteins to 1.5 ml centrifuge tubes Add 0.02 ml of phosphatase assay buffer Preincubate at 30°C for 5 min Add the substrate (>10,000 dpm) For cell lysates, incubate at 30°C for 10 min to 2 hours inside the chamber.
Working inside a dynamic test chamber, Goddard engineers wear protective "clean room" clothing to prevent microscopic dust particles from damaging the sophisticated instrumentation.
Preparation of myocardium was performed in a dissection chamber filled with the protective solution.
The calculations included also the impact of the protective argon atmosphere located in the process chamber.
Following the attainment of one of the termination criteria, the participant exited the environmental chamber and doffed the EOD protective clothing.
And with Republicans controlling both chambers of Congress, the president increasingly protective of his domestic priorities, and the presidential campaign in full swing, the likelihood of political retrenchment seems high.
At least ca. 1 wt.% ash is even needed to generate a protective slag layer at the inner surface of the gasification chamber.
