A Binary-Medium Constitutive Model for Artificially Structured Soils

Sorption of organic compounds to humin from soils irrigated with reclaimed wastewater

Article history: Received 17 October 2007 Received in revised form 11 February 2008 Accepted 26 February 2008 Available online 14 April 2008 Humin is an important fraction of soil organic matter that is known to tightly bind many organic compounds. The objective of this study was to evaluate the role of humin as a natural sorbent in soils irrigated with freshwater and treated wastewater. To mee...

Restoration of retinal images obtained through cataracts.

An optical model for imaging the retina through cataracts has been developed. The images are treated as sample functions of stochastic processes. On the basis of the model a homomorphic Weiner filter can be designed that will optimally restore the cataractous image (in the mean-square-error sense). The design of the filter requires a priori knowledge of the statistics of either the cataract tra...

On a New Group of Bactericidal Substances Obtained from Hexamethylenetetramine.

1 6. The interpretation of the growth of these plants by Mendelian factors is further strongly supported by the distribution of the standard deviations of the plants with different relative sizes. Thus it has been shown that the extreme plants which would be more nearly homozygous and for this reason less variable are, as a matter of fact, some 50 per cent less variable than the plants in the m...
