The agricultural sector accounts for about 13 percent of the total load of greenhouse gas emissions from Sweden (Swedish Environmental Protection Agency, 2007). The Swedish objective to reduce the greenhouse gas emissions with 40 percentage units to the year of 2020, based upon the year of 1990, might imply stricter regulations for Swedish farmers. A regulation or other forms of economic incentives is probably necessary to reduce the emissions originating from the agricultural sector. This study aims to investigate the economic and managerial impact on two agricultural firms with differing production system given that a constraint on green house gas emissions is introduced. Gases included in this study are carbon dioxide, methane and nitrous oxide.

Hälso- och sjukvården har traditionellt arbetat kurativt. Tidigare forskning har visat att samhällsutvecklingen de senaste 20 åren, med högt tempo och stora krav, har resulterat i en ökning av stressrelaterad ohälsa, både nationellt och internationellt. Vinsterna med att arbeta hälsofrämjande är uppmärksammat i allt fler studier och det är därför av relevans att studera om Mindfulness-Based Stress Reduction (MBSR), en förgrening av mindfulness, kan fungera som en effektiv och bidragande resurs för ett mer begripligt, hanterbart och meningsfullt liv. Syftet med denna litteraturstudie var att belysa de hälsofrämjande effekterna av MBSR. Tio artiklar valdes för granskning och utifrån artiklarnas resultat framkom två kategorier: Kortvariga hälsofrämjande effekter och långvariga hälsofrämjande effekter.

The Sub-Saharan countries have for a long time struggled with poverty and conflicts which might have proven hostile for investors. The analysis aims to see if there is a significant correlation between foreign direct investments (FDI) and economic growth and which cultural and institutional factors seem to be significant in this correlation. Considered are also other variables and their influence that might explain what motivates and gives incentives for foreign direct investments (FDI) and are used in the construction of a regression analysis. This to see whether there is an effect on the economic growth in relations to FDI. The results show that FDI is of significance to the economic growth in the region and the study shows that corruption seems to be the most significant institutional factor in the correlation with effect on economic growth and the ability to attract FDI..

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

AbstractA systematic replication study was conducted at the training site at the University of Karlstad. Student therapists performed cognitive-behavioural therapy (CBT) as a part of their master?s degree in psychology.  The systematic replication that took place was based on the work of Hiltunen et al. (2013), who evaluated the efficacy of CBT treatment conducted at the training site previously mentioned.

The essay examines through semi-structured interviews the experiences of overcrowded housing, as they are portrayed through the eyes of children aged 8 ? 14. Overcrowded housing has an effect on children?s school performance, general health and is often linked to less capacity for normal social consumption. Yet there seems to be little done in terms of interrogating children about how they perceive their situation here and now.

This diploma work has been carried out in collaboration with the building contractor Sh Bygg Fastighetsutveckling AB in Uppsala with the intention to investigate how the height of a building affects various energy aspects such as transmission losses, infiltration, and the specific energy usage. Three different reference objects have been studied. The reference objects have been simulated for four different heights in the calculation program VIP-Energy.The results show that an increase in floor number can lead to both advantages and disadvantages. As the number of floors increases, transmission losses per square meter floor area decreases. However, as the height of the building increases, the reduction rate decreases.

Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity in biosorbing heavy metals.

Storage of biomass is associated with problems like heat development, biomasslosses, and reduction of the fuel quality. Certain processes such as biological- andchemical degradation are responsible for these storage problems. This master?sthesis was carried out at Vattenfall Research and Development AB and is alignedtowards quantifying the biomass losses from short-term storage (1-2 months) ofbark and recovered wood. The biomass was stored in outdoor piles during differentseasons, campaign 1 (summer) and campaign 2 (autumn).

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.

In 2013 a new emission standard for heavy trucks was introduced and hence a number of new parts was brought in to Scania CV AB. This created a need for modifications in the silencers flow. The flow is highly complex involving several suppliers, call off methods and different models of silencers. The aim for this project was to improve the existing silencers flow. The flow, from supplier to assembling, has therefore been mapped.

The purpose of this report is to investigate the possibilities with drain water heat recovery (DWHR) in residential buildings. Information and relevant theory has been collected and summarized in this report. Calculations have been done for given scenarios to evaluate profits. DWHR heat exchangers use simple technology and have long life-time. The heat exchanger is connected to outgoing drainage pipe and incoming cold-water supply so countercurrent flow is accomplished.

Testformen utvärderades digitalt med avseende på TAC och total färgförändring.

The UN has a goal to gender-mainstream all politics, but its politics in climate change is not gender-sensitive. The Swedish government has the same goal concerning gender mainstreaming, but does the Swedish politics of climate change reach this goal? The aim of this paper is to examine the relations between the Swedish politics of gender and climate change. In addition, the aim is also to investigate how gender is constructed in the climate politics. To reach these aims, an institutional, policy and gender analysis is used.
