… from one regime in to a completely different one. That will result in loss, or degradation, of ecosystem services such as denitrification, phosphor sedimentation and adsorption, vegetation uptake and infiltration. The results of this study are based upon area calculations of …
Manuellt dödade träd vs självdöda
… being smaller than debarked alder. There was also a significant difference in degradation rate of birch, with natural birch snags being less decayed than the high cut and girdled birch. There was no difference in the degree of decay for alder. 69 % of the trapped longhorn …
I Sverige finns uppskattningsvis mellan 4000 och 8000 stycken deponier. De flesta av deponierna är nedlagda och år 2001 fanns det 142 stycken aktiva deponier för hushållsavfall. År 2010 hade antalet minskat till 76 stycken. Vid nedbrytning av organiskt material i deponier bildas …
Modellutveckling och känslighetsanalys
… the on the other hand, showed very small quantities of both glyphosate and its degradation product AMPA (aminometylphosphateacid) in both the embankment and in the groundwater. The sensitivity test showed that the parameter half-life and Kd-value (adsorption capacity) were the …
… Itis believed that the enzyme is primarily involved in intracellular protein degradation, where itcooperates with the proteasome and other peptidases to degrade proteins into free aminoacids. These amino acids can subsequently be used in the production of new proteins. The aimof …
Optimering av beredningsparametrar för titandioxidbeläggning på polyestersubstrat ämnad för vattenrening
… layer of TiO2 depending on the coating technology used. Decolorization by degradation of methylene blue was studied under a solar energy AM 1,5 lamp. The samples were evaluated by reading the chroma value of the color solution at specified moments. To obtain more information the …
… with lower biodiversity than in the natural forest. One way to limit forest degradation is to rehabilitate the present large areas of secondary forests. However, there is a lack of knowledge concerning the ecology of tropical tree species and further studies would be …
… soil organic material and increased soil acidity are problems associated with degradation of soils and hence less sustainable agriculture. In this thesis, the effect of different agricultural systems on soil organic matter, pH and yield was examined. The systems examined are a …

… manner and used to cook grain and Icelandmoss and exposed to an organized biodegradation experiment inside an incubatorfor later analyzes with the GC-MS-method. Tests were also taken from pottery,grain and Iceland moss that had not been exposed for a biodegrading attempt.The …
… the travel agents work on site to any great extent and in some places land degradation is obvious. My conclusions are that ecotourism certifications have the potential to become an important tool in creating more sustainable travel, but much work remains to achieve this. Very …
Kemin vid nedbrytning av etanol i kroppen, dess betydelse för kroppens kemiska processer i övrigt samt dess betydelse för hälsa och sjukdom
… predominately in the liver. The enzyme alcohol dehydrogenase catalyses the degradation of ethanol to acetaldehyde. Acetaldehyde is even more toxic than ethanol and it is degraded by the enzyme aldehyde dehydrogenase. In chronic alcoholics other chemical processes such as the …
