The effect of agro-waste co-digestion and sludge disposal on carbon footprint in municipal wastewater treatment plants
PublicationThe study presents analysis of the carbon footprint (CF) in 6 wastewater treatment plants in northern Poland with a special focus on the effect of co digestion of sewage sludge and food waste. Although co-digestion increases the on-site energy production, but it has a negative effect on the total CF. To overcome the negative effect, several sludge disposal scenarios were analysed and their effect on the CF reduction was determined....

Low-energy positron scattering from gas-phase pyrimidine: A quantum treatment of the dynamics and a comparison with experiments
PublicationWe are reporting detailed quantum scattering calculations that describe the diffusion of a beam of low-energy positrons interacting with the pyrimidine target as a gas-phase partner. The calculations have employed an essentially ab initio model for the short-range correlation interaction and for the electrostatic interaction of an impinging positron and the electron+nuclear structure of the target molecule at its equilibrium geometry.
