SUBJECTS claws

In the examination of ores of the second claw, charcoal atone is insufficient to effect the decomposition, and therefore a flux Is employed which, by combining with the silieious matter, liberates the oxide of zinc, and renders it subject to reduction by the carbonaceous matter. Lime or magnesia are tho agsuts usually adopted,.

Figure 25 Mummified avian tissue an Adelie penguin from a cold desert, Antarctica, dating to 1030 years bp, from which ice-mummified specimens of bone, feathers, skin, and claw (inset) have been subjected to Raman spectroscopic analysis to determine the survivability of different keratotic materials in an ice mummy.

The small transport surface in the main airways (which could lead to the accumulation of secretions) is compensated in normal subjects by greater velocity related to higher ciliary beat frequency. The most important transport mechanism of mucus in the bronchial tree is mucociliary transport. This movement takes place by coordinated activity of cilia that cover the bronchial surface of the airways. Ciliated cells are found in the airways from the trachea to the terminal bronchioles. Each cell contains about 200 cilia, all of which end in little claws. The cilia beat in the direction of the oropharynx with a frequency of about 8 to 15 Hz. The claws of the cilia reach the mucus gel layer and push this layer towards the oropharynx. The recovery beat in the direction of the bronchioles takes place only in the periciliary sol layer. The cilia normally move the mucus at 1 mm/min in smaller airways and at up to 2 cm/min in the trachea (1,4,6).
