Modeling of waterborne pollution of roadside soils

Motor transport and road maintenance are the determining factors of environmental pollution in the roadside zone. The main acceptor of pollution in this case is the soil. In connection with the complexity of the application of instrumental control methods, it is perspective to carry out the monitoring of roadside territories on the basis of mathematical modeling. The objective of the study is to develop a model of vehicle emissions impact on roadside soils with washout from the road bed. As a physical model we will consider roadside underlying surface covered with a layer of raindrops. According to the physical model, pollutants are absorbed by rain drops when falling on the underlying surface. Movement of pollutants down the whole depth of soil profile is carried out under the action of filtering the contaminated liquid in the granular material of soil. Analytical dependencies have been obtained allowing to predict the roadside ecosystem pollution from exhaust emissions. Soil contamination with liquid effluents resulting from the dissolution of sulfur dioxide in atmospheric precipitation has been calculated

THE SNP-MED SYSTEM FOR ANALYSIS OF THE EFFECT OF SINGLE-NUCLEOTIDE POLYMORPHISMS ON THE FUNCTION OF GENES ASSOCIATED WITH SOCIALLY SIGNIFICANT DISEASES

This paper describes the SNP-MED modular computer-based information system for estimation of the influence of single nucleotide polymorphisms (SNPs) on the function of genes associated with the risk of socially significant diseases. The system includes software components Genomics, Proteomics, Gene networks and the Information resource database (BDIR)

NESTOR experiment in 2003

NESTOR is a submarine high-energy muon and neutrino telescope, now under construction for deployment in the Mediterranean close to Greek shores. The first floor of NESTOR with 12 optical modules was deployed successfully in March 2003 together with the electronics system. All systems and the associated environmental monitoring units are operating properly and data are being recorded. The status of the NESTOR project is presented. We outline briefly the construction of the deepwater neutrino telescope, properties of the NESTOR site, infrastructure of the project, the deployment of the first floor, and its current operation. The first data are presented and plans for the next steps are summarized. © 2004 MAIK "Nauka/Interperiodica"
