There are many and various exposure systems available for the assessment of inhalable products; they differ in size, cost, mechanics, and paired exposure chamber.
We also placed each mating pair in a small plastic box (7 cm × 7 cm × 5 cm) that was then placed inside a larger plastic box (17 cm × 12 cm × 6 cm), which was lined with packing material on three sides to minimize the mating pairs exposure to other mating pairs under observation.
In an eyeblink conditioning test, repeated paired exposure to an air puff on the cornea (US: unconditioned stimulus), which evokes a reflex blink, and a tone (CS: conditioned stimulus), which by itself does not evoke a blink, results in a blink in response to not only the air puff but also the tone alone (CR: conditioned response) (Domjan 2005).
In all cases, the joint toxicity from the paired exposures resulted in AChE activities that were significantly lower than carrier controls (one-way ANOVA; p< 0.05).
The 4,000-word 4,000-wordve the pair huge exposure in the city, not least because the reporter interviewing them, Monica Hesse, was stopped and searched by police in the process.
Although multiple regression analysis provides an effect estimate for each pair of exposure and outcome variables, it is prone to multiple testing problems and chance findings.
In each pair of exposures the participant was blinded to the exposure (clean air or ozone), but we could not blind participants to the temperature.
The blue light receptor cryptochrome that could form radical pairs after exposure to blue light was suggested to be a magnetoreceptor based on the proposition that radical pairs were involved in the magnetoreception.
High levels of drinking over a long period of time will impact one's health, and it's even more risky when paired with exposure to other carcinogens, such as from smoking.
