Attachment measures different aims in mind. Shaver and Fraley note: "If you are a novice in this research area, what is most important for you to know is that self-report measures of romantic attachment and the AAI were initially developed completely independently and for quite different purposes. One asks about a person's feelings and behaviors in the context of romantic or other close relationships; the other is used to make inferences about the defenses associated with an adult's current state of mind regarding childhood relationships with parents. In principle, these might have been substantially associated, but in fact they seem to be
Electrical mobility from exhaust gases on an industrial scale. The particles are given a charge by exposing them to ions from an electrical discharge in the presence of a strong field. The particles acquire an electrical mobility and are driven by the field to a collecting electrode. Instruments exist which select particles with a narrow range of electrical mobility, or particles with electrical mobility larger than a predefined value. The former are generally referred to as "differential mobility analyzers". The selected mobility is often identified with the diameter of a singly charged spherical particle, thus the "electrical-mobility diameter" becomes a characteristic of
