Blood and Air Volumes in the Avian Lung
Poultry Science, 1968 Abstract HISTOLOGICAL examination of birds’ lungs indicates a considerable variation in air and blood volumes (Olander et al., 1967). However, in order to obtain quantitative estimates of these changes, methods are needed which can be applied to the entire organ. Such information is of importance in evaluating respiratory function in conditions where

The Measurement of Air Supply Volumes and Velocities in Cleanrooms [PDF]
International Journal of Ventilation, 2010 Air supply volumes and velocities in cleanrooms are monitored by airflow measuring hoods and anemometers but these measuring methods can be inaccurate if used incorrectly. It is demonstrated in this article that measuring hoods are accurate if the air supply passes evenly out of the hood, as occurs when the air volume is measured from a four-way ...

Air volume measurement of 'Braeburn' apple fruit [PDF]
Journal of Experimental Botany, 2004 The radial disposition of air in the flesh of fruit of Malus domestica Borkh., cv 'Braeburn' was investigated using a gravimetric technique based on Archimedes' principle. Intercellular air volume was measured by weighing a small tissue sample under water before and after vacuum infiltration to remove the air. In a separate procedure, the volume of the
