Vad styr svenska samers utbud av renkött?
Den svenska rennäringens primära inkomstkälla är försäljning av renkött. Syftet med denna uppsats är att undersöka ett antal faktorers inverkan på utbudet av renkött. Metoden ordinary least square har använts för att göra en ekonometrisk studie baserad på statistik för åren 1980-2003. De faktorer som testats är total ersättning, vilken inkluderar avräkningspris samt kvantitetsbaserad subvention, och renstammens storlek. Resultaten i vår undersökning visar att total ersättning inte är signifikant på någon testad nivå, däremot fann vi att renstammens storlek hade positiv korrelation med utbudet på renkött.
Möjligheter att minska kväveutlakningen genom att anpassa kvävegödslingen till variationer inom stråsädesfält
Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.
Bland boktips och länksamlingar : En undersökning av de svenska folkbibliotekens webbplatser för ungdomar
The public libraries were quick to adapt to the changes that the Internet brought on, and today library websites are an important part of the public library. To meet the needs of teens today, the library website could offer a range of contents to make it an attractive place on many levels; both the academic needs as well as social and recreational needs should be addressed.The aim of this thesis is to evaluate public library websites for teenagers in Sweden, and to examine how well the websites address the developmental tasks and needs that teenagers have. The method used is website evaluation, one quantitative and one qualitative. A total of 60 public library sites for teenagers were evaluated, using 11 criteria based on Havighursts developmental tasks. The quantitative evaluation measured how many functions each website had per criteria, and showed that the majority of the sites had one or two functions for most of the criteria.

The study is a quantitative content analysis, containing a total number of 245 articles.
Järnets förekomst i grundvattnet i isälvsavlagringar i Dalarna : Bakgrundshalter och rörmaterialets inverkan vid grundvattenprovtagning
A study has been performed that investigates the variation of iron content in groundwater.The study was initiated by Midvatten AB, which noticed that the iron content in groundwater samples can vary greatly over small distances. The purpose of this study was to geochemically and geohydrologically determine the factors that influence the content of iron and manganese in groundwater from a selection of eskers in Dalarna, and determine how to best sample groundwater with the method used by Midvatten AB. An evaluation was made of how the vertical variation in soil material, water composition, pumping time and pipe material affects the content of iron in groundwater. Piper diagrams were used to study the relationship between the chemical composition of the groundwater and the content of iron and manganese in groundwater samples from the studied areas. The groundwater from the studied areas was then classified in the Piper diagrams, according to the content of the major ions.

Utvärdering av ett silotorksystem för spannmål utrustat med omrörare :
The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.
Överföring av radiocesium till potatis vid olika nedfallstidpunkter :
Agricultural land could be polluted by radioactive substances after a fallout. We would then need information about the level of contamination to decide whether the crops could be utilized as food under these circumstances. In an experiment carried out during the 1990ies the retention of 134Cs in potato haulm and the transfer to the tubers were studied. The experiment was carried out during three consecutive years. The plants were cultivated in pots under field conditions and the artificial deposition was sprayed directly onto the potato haulm at different times during the growing season.
Mätning av träddelar och flis på Dåvamyran, Umeå energi :
The moisture content in 10 deliveries of tree parts and 10 deliveries of wood residues were measured with different methods to analyze the quality of procedure used at Dåvamyran today. At the same time a survey was made on the measure procedures used at heating plants in Sweden
The majority of the heating plants in Sweden use weight and moisture content as base for payment but at some plants only volume. The moisture content is usually estimated by drying wood chips in an oven but few plants a visual estimation is used. At few plants moisture content is estimated spectroscopicily. The techniques using near infra read light and other electromagnetic are still at a test stage.
The methods of measurement used today are quit unreliable for the individual deliveries and there is a risk for systematic mistakes.
Samverkan mellan nya cementtyper och tillsatsmedel för betongtillverkning
Cement manufacture accounts for 3-5 percent of total global carbon emissions. There is a growing interest in reducing the environmental impact and conserve limited natural resources. In cement production, clinker productions consume 87.5 percent of the total energy consumed in the cement manufacture.Cementa has since many years, focused on reducing the environmental impact of cement production. The work has involved the entire production process from selection of alternative fuels to the development of cement with less clinker content. During 2013/2014, two new types of cement (Bascement and CEM II / B) will be introduced to the Swedish market.

Turbiditet som ersättningsmått för totalfosforhalt i kustmynnande vattendrag i Östergötland
Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.
Sagostunder på folkbiblioteket: ur sagostundsledarens perspektiv.
