A Small Parts Test Fixture (SPTF) is a cylinder measuring 2.25 inches long by 1.25 inches wide determines whether a choking hazarding warning will be placed on the product. [78] Furthermore, in 2008, the Consumer Product Safety Improvement requires any advertisements or websites regarding sale of a product to display choking hazard warnings.
Preaspiration is comparatively uncommon across languages of the world, [4] and is claimed by some to not be phonemically contrastive in any language. [5] Ladefoged & Maddieson (1996) note that, at least in the case of Icelandic, preaspirated stops have a longer duration of aspiration than normally aspirated (post-aspirated) stops, comparable to clusters of [h] +consonant in languages with such ...

At one point, it was thought that a lack of the gag reflex in stroke patients was a good predictor for dysphagia (difficulty with swallowing) or laryngeal aspiration (food or drink entering the larynx), and was therefore commonly checked for. However, in one study, 37% of healthy people did not have a gag reflex, yet all subjects except for one ...
Diff-Quik may be utilized on material which is air-dried prior to alcohol fixation rather than immersed immediately (i.e. "wet-fixed"), although immediate alcohol fixation results in improved microscopic detail.
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
