Conventional soil improvement techniques can lead to permanent soil pollution or emission of carbon dioxide. It is therefore a challenge for engineers to design alternative sustainable and cost-effective grouting techniques. In Microbial Induced Calcite Pr ...
We propose a mathematical framework for the general definition and computation of travel time distributions defined by the closure of a catchment control volume, where the input flux is an arbitrary rainfall pattern and the output fluxes are green and blue ...
A process based on partial nitrification and recirculation into the anaerobic digester was studied to remove nitrogen from digested manure and thus reduce enhanced gaseous ammonia emissions due to on-farm biogas production. An anaerobic reactor representin ...
Soil pollution is a major environmental problem actually in China and in the world. It increases environmental risks and can affect humans through the food chain. Like solutions to clean-up the soils are generally expensive and can have side effects on env ...
This paper deals with modelling the mutual feedbacks between runoff production and geomorphological processes and attributes that lead to patterns of equilibrium soil depth. Our primary goal is an attempt to describe spatial patterns of soil depth resultin ...
We address the problem of pollution attacks in coding based distributed storage systems. In a pollution attack, the adversary maliciously alters some of the stored encoded packets, which results in the incorrect decoding of a large part of the original dat ...

Site-controlled InGaAsN quantum wires (QWRs) emitting at 1.3 lm at room temperature were grown on V-grooved GaAs substrates by modulated-flux metallorganic vapor phase epitaxy. The nonplanar substrate template is shown to enhance the nitrogen uptake, evide ...
Water quality issues are a major challenge that humanity is facing in the twenty-first century. Here, we review the main groups of aquatic contaminants, their effects on human health, and approaches to mitigate pollution of freshwater resources. Emphasis i ...
The substantial decrease in solubility accompanying the reduction of U(VI) to U(IV), producing the sparingly soluble mineral uraninite, is viewed as a potential mechanism for the sequestration of environmental uranium contamination. In recent years, a vari ...
Investigations of occupational and environmental risk caused by the use of agrochemicals have received considerable interest over the last decades. And yet, in developing countries, the lack of staff and analytical equipment as well the costs of chemical a ...
