Survival and transport of pathogens from manure in the environment depend on a number of complex phenomena. An important question is how the properties of such a complex environment as the soil–manure medium impact the persistence of bacteria within the vadose zone. First, manure can change the partitioning of precipitation water between infiltration (enhanced by solid manure) and surface runof...
single walled nanotubes (swnt) are common interested nanovehicle to make biosensors more sensitive.carbon nanotubes (cnts) have many distinct properties make them to be exploited to develop the nextgeneration of such nano sensors .the keto-enol tautomerization is one of the most common investigatedsubjects of isomerism in this regards, sensors are devices that are able to detect and change the ...
The soils of Gadas, object the present study, are identified on macromorphological, physico-chemical level and indices erodibility related to their properties. analyzes were carried out by standard methods. macromorphological analysis a toposequence made it possible identify five types soils: lithosols which occupy high zones landscape, colluvial (arenosols, regosols) located piedmont, alluvial...
Water requirement to meet agriculture, domestic, industrial and other demands indicate the need for regeneration of waste water. Industrial waste water is being used in dry areas. Waste water of pulp and paper industry (brown with unpleasant smell) is usually alkaline in nature, has high suspended solids, total solids, COD, BOD and toxic odorous substances. It was observed in the study areas th...
transfusion-dependent patients such as those suffering from β-thalassaemia develop a fatal secondary haemosiderosis and consequently a selective iron chelator must be used to relieve such iron overload. 3- hydroxypyridin-4-ones are selective for iron(iii) under most biological conditions, but unlike desferrioxamine, are efficiently absorbed when administered orally. in this study, the synthesis...
With the rise of sustainable development, rehabilitation of brownfield sites located in urban areas has become a major concern. Management of contaminated soils in relation with environmental and sanitary risk concerns is therefore a strong aim needing the development of both useful tools for risk assessment and sustainable remediation techniques. For soils polluted by metals and metalloids (MT...
