Plants, higher Permeability

Soil gas collecting tubes and lysometers to sample soil waters were installed at four locations above sampled drips in Cascade Cave (sites 16 and 17) and X Cave (sites 18 and 19) as shown on Fig. 3. Pco, measured from the gas wells and equilibrium Pco, in the water withdrawn from the lysometers was higher during the summer when plant growth was active and soil temperatures were high, and at any one time increased with depth. The Pco, of sandy soUs with higher permeability tended to be lower than clayey soils, and deep drying of the soils caused a decline in Pco, Some representative values are shown in Table II. 

In some cases with crude preparations from higher plants, it has been shown that the cell volume increased highly, and neoplasmic cell vacuolization was observed. As a result of the administration of polysaccharides, the membranes of Ascites cells showed increased permeability to solutes and, consequently, the cell inhibed more water and swelled. 

The prepared membranes SILMs showed high CO2 permeability (744 barrer) and CO2/He selectivity of 8.6. Furthermore, the stabihty of the membranes at higher temperature (125 °C) approached the range of interest in the capture of CO2 from coal gasification plants. However, higher temperatures could not be reached mainly due to the support failure rather than any effect on the ionic liquid.
