Global water supplies are threatened by climate changes and the expansion of urban areas, which have led to an increasing interest in nature-based solutions for water reuse and reclamation. Reclaimed water is a possible resource for recharging aquife

Greenhouse gas emissions from drained agricultural peatlands contribute significantly to global warming. In a laboratory study using intact cores of peat soil from eight different sites in Sweden, factors controlling the emission of the greenhouse ga

The advent of social media can be seen both as a risk and an opportunity by armed forces. Previous research has primarily examined whether or not the use of social media endangers or strengthens armed forces’ strategic narrative. We examine armed f

It is a well-known fact both among scholars of propaganda and disinformation, and among political leaders that Sputnik and RT are using their news coverage for disinformation purposes to harm Western and European societies. Following the Russian inva
Nitrogen (N) pollution is a major threat to ecosystems and a driver of climate change through emissions of the greenhouse gas nitrous oxide (N2O). Mining activities are increasingly recognized for contributing to N pollution due to undetonated, N-bas

Constructed floating wetlands (CFWs) have been tested in different climatic regions and aquatic habitat types for nitrogen (N) removal from surface water, but there is limited knowledge about their applicability for N removal in cold climate regions.

Explosives used in mining operations release reactive nitrogen (N) that discharge into surrounding waters. Existing pond systems at mine sites could be used for N removal through denitrification and we investigated capacity in tailings and clarificat

Denitrifying woodchip bioreactors are potential low-cost technologies for the removal of nitrate (NO3- ) in water through denitrification. However, if environmental conditions do not support microbial communities performing complete denitrification,
