1. Effects of tillage and straw treatments on earthworm abundance : study in two Swedish long-term field trials
University essay from SLU/Dept. of Soil and EnvironmentAbstract : Earthworms have several functions in the soil, for instance redistribution of organic matter and enhancing plant available nutrients. Earthworms are divided into three ecological groups, with different functions in the soil. The groups are: anecic, endogeic and epigeic. READ MORE

2. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.
University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/BioteknikAbstract : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

3. Washing efficiency in the pulp mill : An evaluation of the washing efficiency in SCA Munksund's pulp mill
University essay from KTH/Fiber- och polymerteknologiAbstract : Munksunds pappersbruk är ett integrerat massa- och pappersbruk som består av två fiberlinjer, en barr- och en lövlinje där båda kokarna är kontinuerliga med efterföljande tvättsteg. En kartering av COD (eng. Chemical Oxygen Demand) och natrium utfördes för båda linjerna för att utvärdera tvätteffektiviteten. READ MORE

4. Reconstructing Past Climate by Using XRF and Loss of Ignition on Loess from Adventdalen, Svalbard : Rekonstruktion av tidigare klimat genom attanvända XRF analys och antändningsförlust på lössavlagringar från Adventdalen, Svalbard
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : By analyzing the texture, composition and chemical composition of loess soils, the reconstruction ofpast climate regimes is enabled, which can improve our understanding of current and future climatechange. Properties such as grain size and composition, mineralogy, organic matter and chemicalcomposition can provide information about which environmental factors were present during thedeposition of the sediment, which can lead to a detailed picture of the climate history of a site.

5. The potential nitrous oxide emissions in a permanent grassland chronosequence
University essay from SLU/Dept. of Forest Mycology and Plant PathologyAbstract : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.
