… in order to achieve desirable properties. These different parts can consist of organic material or in-organic material (mostly gravel). Gravel and many other materials in the top-layer are environmental friendly, and therefore, easy to get rid of. However, when mixing …
… and germination. The aim of this study was to investigate and characterize how organic nitrogen affects the first emergence and formation of the root system in maturated and germinated Norway spruce somatic embryos and plants. The present study suggests that organic nitrogen …
En studie om oregelbundna arbetstider på Ålands hälso- och sjukvård
… we choose to eat since food production has a big impact on the environment. In organic production the aim is to have a natural production process, where environmental impacts are minimized. By choosing organic food it is therefore possible to contribute to a better environment …

Analys av tungmetallers distribution inom jordprofiler tagna från Abiskoområdet, nordvästra Sverige
… towards the outer domains where the latter contained the highest amounts of organic matter that bind these metals the Pb and Hg concentrations increased. The highest concentrations of Pb (47 mg/kg) and Hg (359 µg/kg) are found in the surface layer (about7 cmdeep) at the edges of …
… chlorophyll. The sediments were analyzed for nitrogen, phosphorus, water and organic level and the benthic organisms were determined to species when possible. The levels of nitrate, phosphate and chlorophyll were correlated with each other but also with the distance from the …

… One technique to utilize and convert energy into electricity is the ORC (Organic Rankine Cycle). This process is based on the Rankine process (the steam process), the difference from the traditional Rankine process is that instead of water as a working medium, an organic …
… is biogas, which is produced though a digestion process of different organic materials in a biogasreactor. Organic substrate that comes from farms has the biggest potential to increase the production of biogas in Sweden. Primarily crops from farms, but also waste products like …

Optimering av beredningsparametrar för titandioxidbeläggning på polyestersubstrat ämnad för vattenrening
… ha en påverkan på den vattenrenande effekten.In this bachelor essay work organic contaminants are removed from water using textiles, whose surface is coated with nanoparticles of titanium dioxide. When titanium dioxide is illuminated with UV radiation a photocatalytic reaction …
… to move back some of the production to Sweden. There is an increasing trend of organic and locally produced products, increasing the demand on products produced in Sweden. The project aims to provide individuals and companies with support for them to explore their opportunities …
Fermented liquid feed is well known for its health promoting effects on piglets. High levels of lactic acid are desired in the feed together with low levels of acetic acid and certain biogenic amines. Limits for acetic acid have been suggested to be 30-40 mmol/kg to avoid a …
what are the soil requirements”
… Usambara, Tanzania. The soils were analyzed for bicarbonate extractable P, organic C, total N, electric conductivity, pH, C:N ratio and bulk density. Water infiltration rate was also measured. Soil samples from the soil profiles were also analyzed for texture, effective cation …
… to achieve good soil conditions sustainable management is a key. Loss of 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 …
