This study targeted "the composition of substances" segment of junior high school chemistry classes and, furthermore, involved the design and development of a set of inquiry-based Augmented Reality learning tools.
The effects on the segment of the different vasoactive substances was tested by first recording the spontaneous resting diameter of the artery segment and define it as the maximum dilatation possible.
In the case of significant relaxation the negative logarithm of the concentration of substance required for dilatation of the vessel segments to half of their Emax.
The maximum dilatory response (Emax for each tested substance was obtained for the vessel segments as the percentage tonus relaxed by the maximum concentration of substance from the PGF2α- or K+-induced pre-contraction towards the resting tonus sampled before the lowest concentration of substance was added.
One indicator type addresses the number of drugs within the DU90% segment (defined as substance of the same ATC code, fifth level).
The maturation of the neuromodulatory action of substance P (SP) was investigated in tracheal smooth muscle (TSM) segments isolated from rabbits aged 2-24 wk.
Accordingly, Yoshida et al. (1988) found a loss of substance P- and enkephalin-immunoreactive, supposed cholinergic, nerve fibres in a megacolonic segment.
The contractile effects of substance P (SP) were studied in isolated rabbit tracheal smooth muscle (TSM) segments in vitro.
A subpopulation of substance abusers begin using drugs primarily as self-medication, entering the spiral at the negative reinforcement segment.
One wildcard was that a considerable segment of the media, while questioning Bush's substance, harbored an intense dislike for Gore -- as the story line went, he was stuffy, or disingenuous, or unresponsive to their inquiries.
In February, Khan, who has been sober for eight years, opened up about her battle with substance abuse in a segment of ABC News' "Cause Celeb" with celebrity stylist Phillip Bloch.
