a model study
… of daily standardweather data and discharge, data on soil water content, soil nitrogen and nitrogen contentsin drainage water from to experimental fields grown with spring cereals. The model wascalibrated against the 4-year data set based on a GLUE-procedure in which a number …
… value (MK), air quality index of the forest stand/sample plot (LKI) and nitrogen impact value (N) were calculated and it was tested if there was any difference between the sites. Twenty-four species were observed in total, and Parmeliopsis ambigua and Hypogymnia physodes were …
… effective but has many links to environmental problems. The phosphorous and nitrogen-based is kinder to the environment but often with less efficiency than the halogenated. When phosphorous and nitrogen flame retardants are combined, the two often get better features.This …
… of inshore seas, lakes and watercourses is mainly due to leaching of nitrogen and phosphorus (P) from agriculture. Many efforts are made to reduce the lea-kage of phosphorus in Sweden and the Baltic Sea countries. Phosphorus is also a finite resource and the mining of good …
a possibility to reduce nutrient levels and produce commercially interesting metabolites
… of the drainage water varies over the season, but is generally high in nitrogen. Considering a sustainable development of the Swedish greenhouse industry, it is therefore important to reduce the nutrient levels in the water before it is drained away. Chlorella vulgaris is a …
… as an aid to determine if there is a need of complementary fertilization with nitrogen (N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha. The possibility to assess the need of N depends on the strong relation that exists between …
… carbon sequestration. Field measurements were made on the total SOC and nitrogen amount, along with soil physical and chemical attributes, between different land use systems , also to analyze if there will be any positive effect on soil chemical and physical properties with the …
En studie utifrån stabila isotoper
… in the Baltic sea. This was done by analysis of the stable isotopes of carbon, nitrogen and sulphur. Thre were never any living population of these mammals on Gotland during the Viking age. ?34S-values of sulphur from this study was compared with earlier research and by studying …
… and 4.24 years for combustion of MSW.Emissions of carbon dioxide and nitrogen oxide are both higher when incineration of 540 kg RDF takes place in a fluidized bed, than of a ton of MSW in a stocker grate incinerator. Emission of carbon dioxide is 17,7 percent higher and for …
To investigate effects of nitrogen on in-lake CO2 and CH4 production during winter, three pair of lakes was subject for a fertilizing experiment in which one lake in each pair was fertilized with nitric acid (HNO3) directly into the water column in the summer of 2012. The lakes …
… medium is changed to a low-concentration ammonium medium. The ammonium-binding nitrogenase in the heterocysts does not work in an oxidative environment. During oxidative stress, N.punctiforme produces Dps (DNA binding protein from starved cells) which protects DNA. In the …
… impact of clear-cut on lake water quality (dissolved organic carbon (DOC), nitrogen, phosphorus and pH) has been investigated, based on 23 lakes sampled during autumn. Data for additional 15 lakes sampled for the Swedish monitoring program were also used. Lakes were classified …
… the life cycle decrease in production. This because the ground can suffer from nitrogen deficiency as a result of prescribed burning. This phenomenon can be prevented with the use of nitrogen fertilization.
a study on growth conditions for the planted regeneration in a rainforest rehabilitation project
… 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 in the area light …
