Permeability characteristics of calcium alginate films

Journal of Controlled Release, 1988
Abstract The permeability of acetaminophen in hydrated calcium alginate films was measured in side-byside glass diffusion cells. The films were prepared by ionically crosslinking dry sodium alginate films by immersion in aqueous solutions of calcium acetate (0.1 to 1.0 M ) for 1 to 15 minutes.

Study on the Permeability Characteristics of Coarse-Grained Soil and its Permeability Rule

Advanced Materials Research, 2014
The permeability of coarse-grained soil is influenced by many factors. The results of permeability tests in different conditions indicate the effects of coarse-grained soil dry density of , fines content P5,void ratio e and nonuniform coefficient Cu to the permeability coefficient.

Microbial Characteristics of a Reactive Permeable Barrier

2001
Abstract : Permeable reactive barriers for treatment of subsurface organic and inorganic contaminants is recent technology. Little research has been done to its potential problem areas and to measure long-term performance. Observed flow reductions and performance deterioration is typically postulated as a consequence of chemical precipitation.

The Permeability Characteristics of the Nuclear Envelope at Interphase

1964
It is well known that a variety of essential cellular processes are dependent either wholly, or in part, on the cell nucleus. Similarly, the nucleus, in order to carry out its functions, is dependent on the cytoplasm (Brachet 1957; Mirsky and Osawa 1961).
