16. Ash transformation in thermochemical conversion of different biomass resources with special focus on phosphorus
Abstract : A great potential exists for increasing the use of bioenergy in thermochemical processes by utilizing agricultural biomass, forest residues, and sewage sludge that have high availability. Many of these biomass assortments have high ash contents with relatively high concentrations of ash-forming elements such as potassium (K), calcium (Ca), silicon (Si), and phosphorus (P). READ MORE

17. Filter beds for on-site wastewater treatment : Towards more reliable estimations of phosphorus retention
Abstract : Phosphorus (P) is an important plant nutrient and essential for life. However, thephosphate rock used for fertilizer production is a non-renewable resource and itsproduction is expected to peak. At the same time, the discharge of P into naturalwaters is causing eutrophication, a severe problem in areas such as the Baltic Sea. READ MORE

18. Sustainable phosphorus removal in onsite wastewater treatment
Abstract : Aquatic eutrophication is a serious environmental problem that occurs all over the world. To protect surface waters (in particular the Baltic Sea), the regulatory pressure on onsite wastewater treatment (OWT) systems have increased in Sweden. READ MORE

19. Co-combustion of Biomass and Waste Fuels in a Fluidised Bed Boiler - Fuel Synergism
Abstract : The objective of this work was to study co-combustion of biomass and waste fuels in a circulating fluidised bed boiler and to detect synergy effects with respect to flue gas composition and ash formation during boiler operation. It was also the aim to perform supplementary thermodynamic equilibrium calculations in order to support the experimental results. READ MORE

20. Leishmania donovani Lipophosphoglycan : Modulation of Macrophage and Dendritic Cell Function
Abstract : Leishmania donovani is a blood-borne tropicial parasite, which infects humans through bites by Phlebotomus sandflies. The parasite survives and multiplies inside macrophages in inner organs, and causes the deadly disease visceral leishmaniasis (Kala-Azar). READ MORE
