Soils are the major terrestrial reservoir of persistent organic pollutants, and thus net volatilization from soil, when it happens, may exert a control on the atmospheric occurrence and variability of organic pollutants. Here, we report and discuss the concentrations of legacy organochlorine pesticides (OCPs) such as hexachlorobenzene (HCB), hexaclorocyclohexanes (HCH) and dichlorodiphenyltrich...

Those magnificent pictures of Earth from space, among the most humanly important and evocative results from the placing of manned and unmanned satellites in orbit during the last several decades, have shown us that underneath the clouds most of the world is blue. Viewed in this way from space, Earth is seen as a planet covered mostly by water, and most of that water is seawater. This thin layer...

Most evapotranspiration over land occurs through vegetation. The fraction of net radiation balanced by evapotranspiration depends on stomatal controls. Stomates transpire water for the leaf to assimilate carbon, depending on the canopy carbon demand, and on root uptake, if it is limiting. Canopy carbon demand in turn depends on the balancing between visible photon-driven and enzyme-driven steps...

Previous research into the religious life of Roma in Serbia has mostly been based on questionnaires and surveys of sociologists of religion on their religious (current connection to religion and church) and confessional (belonging to a religion) self-identification, on the ritual celebration of two religious-ethnic holidays: Vlasuljica (January 14, St. Basil) and Đurđevdan (May 6, St. George), ...

a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...

Distributed acoustic sensing in vertical seismic profile (DAS-VSP) acquisition plays an important role reservoir monitoring. But the field data can be noisy and associated with missing traces which affects imaging geological interpretation. Therefore, DAS-VSP reconstruction a high signal-to-noise ratio (SNR) is worth studying. There are no exact relationships between signals noise t-x domain da...

Aquaculture is growing rapidly around the world. In Brazil, fish farming in net tanks has high potential due its large number of reservoirs. However, cultivable areas with a density may be more susceptible to eutrophication compared other production systems, and impair ecosystem where they are installed. Therefore, attention needed this type system avoid environmental impacts. The objective stu...
