Studiens målsättning var att undersöka förutsättningarna för att utsläppshandel skulle kunna vara ett samhällsekonomiskt effektivt alternativ för att internalisera ex-ternaliteterna vid bruk av handelsgödsel. I studien fokuseras förutsättningarna för utsläppshandel med kväve i de svenska jordbruken. Utgångspunkten ligger i kväveutlakningens geografiska variabel, något som leder till att utsläppen orsakar differentierade externa kostnader. Tillvägagångssättet bygger på en redogörelse för de faktorer som bidrar till att kväveutsläppen orsakar differentierade externa kostnader och konsekvenserna för inrättande av styrmedel utifrån miljöekonomisk teori. Dataunderlaget utgörs av en kartläggning av jordartstyper, redogörelse för skillnader i vattendragens retention i Sverige och effekterna av reningsinsatser i Östersjön.

The Swedish sports retail industry has experienced extensive growth during the last decade, and this has attracted new entrants to the market, both start-ups and international followers. This has inevitably put more pressure on incumbents, which are now confronted with major challenges as how to retain their customers and market shares. Customer loyalty has been proved to be an important factor for customer retention and proposed to constitute inertia of switching behavior. In light of this problematization, the purpose of this study is to describe the underlying factors of loyalty and whether purchase habits could further explain customer loyalty. The aim is also to understand the strategic implications of the factors involved.

The aim of this thesis was to examine if it is possible to keep nitrogen in the form of nitrate(NO3-) in ponds from one season to another by keeping a high concentration of oxygen in thepond water. This hypothesis was tested by doing a lab experiment where two systems werecompared according to nitrate concentration. One system had high concentration of oxygen inthe water and one had low concentration of oxygen. Before the main experiment wasconducted I did a pilot study to test the system setup and included parameters. The result fromthis study and the main study did not show the same result.

The aim of the study was to investigate if methane emission in a constructed wetland changed in a diurnal pattern correlating to temperature, humidity or light conditions. The gas measurements were carried out with a static chamber technique. The wetland (in Nykvarn outside of Linköping, Sweden) takes care of wastewater to reduce the nitrogen loads. Measurements were carried out at three different occasions in the summer of 1998 on two sites in the wetland. One site was close to the inflow, inhabited by Lemnaceae, and another site was located further downstream inhabited by the emergent macrophyte Typha latifolia.

I den här uppsatsen har vi undersökt vilka värderingar drivkrafter och behov som finns bland fordonstillverkaren Scanias unga akademiker, vilka i undersökningen går under benämningen Young Professionals. Detta i syfte att utröna varför Young Professionals lämnar Scania och vilka faktorer som är avgörande för att skapa ett attraktivare Scania bland denna målgrupp samt att komma fram till lämpliga åtgärder som i största möjliga mån kan förmå dem att stanna inom företaget. Undersökningen bedrevs genom användande av kvalitativa intervjuer och fokusgrupper vilket resulterade i ett antal faktorer framkom som viktiga för denna målgrupp.Dessa faktorer är chefskapet, missnöje med företagets engagemang och tillvaratagande på den enskilde individens driv, motivation och kunskaper samt inre processer som är alldeles för segdragna vilket mynnar ut i frustration hos YP och därigenom leder till motivationstapp..

Forestry in Sweden is currently conducted in a manner aiming at equating the production objectives and the biodiversity. To ensure that biodiversity is maintained, patches that are considered to be valuable now or in the future is saved in final fellings. How the tree retention areas will grow into the future forest stands is yet unknown.The purpose of this study was to visualize how different scenarios of natural consideration taken at final felling will evolve in a long term perspective, for two rotation periods. Projections of the forest conditions were executed with the decision support system Heureka and its applications PlanStart and PlanWise. The information about the projected forests was then used for the visualizations which were created in the software Visual Nature Studio.

Under studietiden kan studenten möjligen inte ses som en lönsam kund för banken. Det finns dock en potential inför framtiden då studenten blir yrkesarbetande eftersom dennes inkomst förväntas att öka. Det torde därför finnas ett intresse för banken att kvarhålla studenten som kund vid den kritiska händelsen då denne blir yrkesarbetande. Detta leder fram till magisteruppsatsens syfte, vilket är att undersöka vilken beredskap Nordea har för att kvarhålla studenter som kunder inför och under den kritiska händelsen då de blir yrkesarbetande. Teorier gällande relation, kritisk händelse samt retention (kvarhållande) har använts i magisteruppsatsens studie.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

I have done a case-study about building a new stable for slaughter pigs at a farm close to Kalmar. The farm is able to supply the breeding with cereals and it has enough area to spread the manure on. The most important factors to gain profit, is the cost for building the stable, the price of the feeding-stuff and the growth of the pigs. The discount from the slaughter-house was less important than I thought from the beginning, and it?s a factor that is hard to influence. With the new production of slaughter-pig and cattle that already exist on the farm, the farm will get a well-functioned rotation of crops with lye and autumn rape as interruption-crop.

The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value. Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.

Plant nutrients are important for all life on earth and are also important as fertiliser infood production all over the world. Because of this, plant nutrients are of great valuebut they also bring problems. As an example, the loss of nitrogen and phosphorusfrom agriculture and urban society's sewage systems contributes to some of today?smajor problems in water environment. Another problem associated with plantnutrients is that finite recourses are used in the production of mineral fertilizers.

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.

Climate changes today are mainly caused by anthropogenic activities and the increased emissions of greenhouse gases to the atmosphere and this has raised questions on how to reduce the usage of fossil fuels. Ethanol is a good alternative to conventional gas and has been used in Brazil since the 1970 ?s. In Sweden several newspapers has written about the poor working conditions on many farms thus making the Swedish company SEKAB design a certification for their ethanol to ensure that it can be considered to be a sustainable alternative.Furthermore WWF has developed a certification tool called Bonsucro in cooperation with Coca Cola, Ferrero group, BP and Shell. This is due to the fact that no global certification tool has been available up until now.

Purpose: The Swedish correctional service is on the brink of its biggest expansion in history, due to political investments related to battling a rise in gang related criminality. The purpose of this thesis is to exam and understand the strategic competence supply work from an employer perspective and investigate the elements included in the Swedish correctional service competence supply form a regional perspective. The study specifically focus on what strategies the Swedish correctional service employ to attract, recruit, develop and retain workforce. Theory: The theoretical framework of the study includes among others, a model divided into three different phases (within, in and out) within competence supply, the demand-control-support model, push and pull factors, as well as the two-factor theory. Method: This study has a qualitative approach with semi structured interview as its specific method. A total of seven interviews were conducted with personnel within the swedish correctional service. Results: The main challenges are related to recruitment, staff retention, support of managers, and the fact that many correctional officers do not have time to complete their training before leaving. The latter is particularly significant are of concern.

The aim of this study is to provide a comprehensive overview of C?ronis beeswax varnish by Lefranc & Bourgeois; its contents, aging properties, solubility, and possible removal methods, with G?teborgs Konstmuseum?s ?Gothenburg Museum of Art? collection as the stud??s material? The purpose of the study is to provide a basis for decision-making regarding the treatment of works treated with C?ronis wax varnish. The study is based on contemporary conservation theory and interpretation-based decision-making and utilizes FTIR, microscopy, and solubility tests to examine the properties of the varnish. The study shows that C?ronis does not appear to be harmful to the treated works and has retained its solubility properties and transparency over time.
