The mechanics of the regional airways and tissues was studied in isolated dog lobes by means of a modified wave-tube technique. Small-amplitude pseudorandom forced oscillations between 0.1 and 48 Hz were applied through catheters wedged in 2-mm-diameter bronchi in three regions of each lobe at translobar pressures (PL) of 10, 7, 5, 3, 2, and 1 cmH2O. The measured regional input impedances were ...

however is that the ustuall flat tissue between ai and the trabecula (b) may proje(t backwards as a knob (c). This swelling is granular and does not contain cells (Figs 2 and 3). Here this knob-like bulge has been -demonstrated in five eyes, three knobs w-ere normal and tw,o were malignant melanomata. Generally, the five cases (Figs 2-6), show the different structure of the knob, the prominent ...

Lizards have highly directional ears, owing to strong acoustical coupling of the eardrums and almost perfect sound transmission from the contralateral ear. To investigate the neural processing of this remarkable tympanic directionality, we combined biophysical measurements of eardrum motion in the Tokay gecko with neurophysiological recordings from the auditory nerve. Laser vibrometry shows tha...

This article discusses the information-structural status and the syntax of left and right dislocation constructions in Dutch. Four orthogonal information-structural features are proposed, and their distribution is systematically investigated. Furthermore, it is argued that hanging topic left dislocation, backgrounding right dislocation and afterthoughts are a particular kind of parenthesis. The...
