an investigation of the effect of ageing on the hygienic status of rubber liners and tubes
… and chemical deterioration occurs and cracks, crevices, as well as deposits of organic and inorganic material is formed on the surface. Bacterial colonization can accumulate, especially on ageing rubber equipment and if the cleaning procedure is not functioning properly …
a study on growth conditions for the planted regeneration in a rainforest rehabilitation project
… in the conditions that might affect growth and mortality such as levels of organic carbon, nitrogen phosphorus and clay? The location of this study is in an east facing slope that in parts connect to a creak at the bottom. This area was planted in 2008. For all the planted trees …
evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon
… exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied. The removal efficiency of PFASs was studied in pilot-scale column experiments at Bäcklösa drinking water treatment plant (DWTP) in Uppsala, Sweden …

… of the cultivar Aromata planted in a medium of soil:peat (1:1) enriched with organic nutrients and lime, were fed with comfrey liquid plus Biofer, in three different concentrations. Two different concentrations of BioRika were used as comparison, along with an unfertilized …
… running into the sea. The parameters accounted for are the C/N ratio, total organic carbon (TOC) as well as total nitrogen present (TN) and ?13C in the top ten centimeters of a sediment core retrieved in the Sk?rhamn harbour. All of which gives information of what input is …
… contents of the inner structure, as well as FTIR analysis, which established organic components. The literature studies would culminate in a comparison between the treatments tested on the Vasa ship and other wooden objects from the museum’s collections and the treatments …
… of alarming reports saying that the sludge in addition to heavy metals, toxic organic compounds, also contains brominatedcontaining flame retardants and dangerous infectious matter from hospital waste water. The alarming reports made the LRF in October 1999 to ban all spreading …
… in southern Sweden, with and without natural regeneration of spruce. In the organic layer, beech forests had significantly higher pH and lower C/N-ratio compared to spruce forests. beech forests with spruce regeneration had significantly lower pH, lower CEC and lower BS in the …
… computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine …
… produce VFA by hydrolysis and fermentation of primary sludge. In this way the organic material in the incoming wastewater can be used in biological phosphorus removal. The sludge temperature, total solids (TS) and retention time are regarded as important parameters for a …
avskiljning med mineraliska filtermaterial
… chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that …
… Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied. The experiments were conducted with urban storm water and with a reference solution (10 mM NaNO3), both containing the …
… soil and groundwater sampling, together with the analysis of heavy metals and organic contaminants. The degree of hazard posed by the contaminants, the level of contamination, the potential for migration of the contaminants, as well as the degree to which protection of human …
Title: Organic / Synthetic in today's creative music making. This work intends to find out what synthetically versus organically produced music means for a songwriter / producer as well as for an artist in their everyday role of occupation. What are the positions regarding these …
… osteochondrosis was studied in 64 pigs raised in conventional systems (45) or organically according to KRAVs principles (19). In this blind study the growth plates of distal radius and ulna were examined macroscopically and radiologically searching for pathological lesions. One …
