As the ammonia exposed in testing chamber, the diffusing ammonia molecules adsorb on the TiO2 film sensor surface over time.
To calibrate anemometers to high accuracy, the air flow must have very low turbulence and uniform velocities over the testing chamber cross section.
Previously fear-conditioned and extinction-trained animals were returned to the testing chamber 48 h following extinction training and presented with three footshocks in the absence of the light-CS (0.4 mA, 0.5 s shock, 2 min intertrial interval).
The latest claims about Parchin, located about 20 miles southeast of Tehran, come just a few days after new satellite imagery prompted suggestions Iran had tried to clean up a suspected explosives testing chamber there, as Rick Gladstone reported.
The formed sensing elements were dried at 60 °C for 30 min and then installed into the airtight testing chamber described elsewhere [30].
Subjects were seated inside an acoustically and electromagnetically shielded testing chamber.
A metal band was placed on the left hind paw of the mouse and acclimated in the behavior testing chamber at least 1 hour prior to formalin injection.
The apparatus was isolated within a 73.5×59×59 cm testing chamber that was fitted with overhead fluorescent lighting (14 lux).
On day 2, the paired SFC and RN animals were placed together in testing chamber B, where 1 min of baseline was followed by 8 minutes of continuous tone CS.
Several monitors show the testing chamber in an adjacent room.
On day 1, animals were injected with saline and allowed to habituate to the testing chamber.
