Among the preexposed groups, those receiving 10 mg of amphetamine showed normal rates of conditioning, whereas those treated with either 5 mg of amphetamine or placebo showed LI.
For example, this change could in part come from the increased penetration rate of air conditioning or heating in U.S. households over time.
There were significant differences between income segments of the sample (p < 0.05), with a higher rate of air conditioning at homes of the upper income respondents (>4000 yuan/month, 13.5%).
For example, people in southern developed regions had a higher average rate of air conditioning ownership than people settled in the northern regions (27) where lack of income was the major reason to stop them buying or using air conditioning during heat waves (36).
We used multivariate OLS linear and spatial error and spatial lag regression to analyze the neighborhood-level predictors of these characteristics, using rates of air conditioning access for seniors and area-based measures of surface temperatures as dependent variables, with sociodemo-graphic, built environment, and biophysical characteristics as predictors.
The tendency toward reduction in the firing rate over the course of conditioning has been observed in a recent experiment (Kotani et al., 2006).
Pretransplant factors, relapse rate, GVHD incidence, type of conditioning, and donor type are summarized for cases and controls in Table 4. Relapses were significantly more frequent among patients who died from suicide (52 of 189 patients [28%] versus 81 of 560 patients [15%]; P =.02).
Increasing cue-ambiguity during inter-stimulus-intervals should slow down learning rates of delay-conditioning.
Cholesterol-fed rabbits showed significant facilitation of heart rate conditioning and conditioning-specific modification of heart rate relative to normal diet controls.
And the respective energy saving rate of the two air conditioning design loads in the hall at different storey heights, window-wall ratios, and air supply heights can be compared.
