The aim of this paper is to examine the macroeconomic implications of remittances in MENA and Mediterranean countries. After a brief review of theoretical and empirical literature devoted to macroeconomic performance of remittances, we select the arguments that can be applied to this region and try to identify a significant relationship between...

Shortly after the Chernobyl accident in 1986, vegetation, contaminated soil and other radioactive debris were buried in situ in trenches. The aims of this work are to analyse the structure of bacterial communities evolving in this environment since 20 years, and to evaluate the potential role of microorganisms in radionuclide migration in...

An actinobacterial strain, designated ViU22(T), was isolated from a natural uranium-rich soil and was studied using a polyphasic approach. Cells formed orange-pigmented colonies, were rod-shaped, Gram-positive (non-staining method), non-motile and non-spore-forming. This organism grew in 0-4.5 % (w/v) NaCl and at 15-37 °C, with optimal growth...

Following the Chernobyl accident in 1986, vegetation, contaminated soil and other radioactive debris were shortly buried in situ in trenches. The present work describes the analysis of the structure of the bacterial communities that have been evolving in this environment for more than 20 years. Comparison of the diversities found in soil...

This study investigated the influence of uranium on the indigenous bacterial community structure in natural soils with high uranium content. Radioactive soil samples exhibiting 0.26%-25.5% U in mass were analyzed and compared with nearby control soils containing trace uranium. EXAFS and XRD analyses of soils revealed the presence of U(VI) and...

The diversity of bacterial communities exposed to radioactive contamination in Chernobyl soils was examined by a combination of molecular and culture-based approaches. A set of six radioactive soil samples , exhibiting high levels of 137 Cs contamination, were collected from the T22 trench. Three samples were also collected in nearby soils with...
