To obtain high radiometric accuracy of better than 10%, a double ionization chamber is assigned to each of the spectrometers as primary detector standard.
The southern chamber was assigned to Agnes who died in 1143.
Each chamber was assigned a different temperature treatment: control (no temperature shifts) (C), moderate temperature shifts (M) and extreme temperature shifts (E).
Based on the individuals' spontaneous preference during this pretest phase, the drug-paired chamber was assigned in such a way that saline and morphine groups were counterbalanced and unbiased toward contextual cues.
Chambers were assigned to dietary treatment sequences in a single 4 × 4 Latin square design.
Before initiation of the study, the rats were assigned a chamber (1 through 8) and time of testing (0830 or 1000 hours) in a randomized and balanced way.
Before the initiation of the study, the rats were assigned a chamber (1 through 16) and time of testing (1000 or 1200 hours) in a randomized and balanced way.
Before the initiation of the study, the rats were assigned a chamber (1 through 16) and time of testing (10, 12 or 14 o'clock) in a randomized and balanced way.
Samples that failed to adhere, which became obvious during removal from the culture chamber or during placement into clamps, were assigned an adhesive strength of 0 kPa.
Prior to behavioral testing, the rats were assigned an operant chamber and a time of testing in a semi-randomized and balanced way.
