The goal of this thesis is to design an attachment between a duct and a pod. A pod is what could be compared to an outboard engine for larger vessels. The pod is placed on the outside of the ship?s hull and can rotate 360 ?. A duct is a large steel ring that can be placed around the propeller on the pod to increasethe propulsion force of the ship in lower velocities.

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.

Depressioner återkommer ofta och varje ny depressionsepisod ökar risken för en ny beroende på en allt större känslighet för inre och yttre triggers. Mindfulnessbased Cognitive Therapy (MBCT) har utarbetats av Z. Segal, M. Williams och J. Teasdale som en gruppbaserad behandlingmodell för att förebygga återinsjuknande kombinerar mindfulnesstekniker och kognitiv terapi (KBT) för depression.

The theories used cover both social psychological and cognitive perspectives such as those of Charles Cooley, Johan Asplund and Thomas Scheff..

ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method:  Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine.  Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.

Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS.

Parenting and parental leave in a career context is a highly topical subject in which discussions about gender equality and corporate discrimination against parents occur daily. Media has recently raised the theory of parenting and parental leave as having positive impacts on personal development, such as creativity enhancement, which may promote the individual's work performance. Despite the subject's significant value for society and organizations, no scientific research is to be found. This paper examines how an individual's creativity at work is affected when becoming a parent and if parental leave has any contributory effect. Furthermore, the paper identifies and scrutinizes four creativity theories that may help explain these changes in creativity.

The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.

In Sweden, the eutrophication of lakes, water courses and the coastal areas is considered the major threat to aquatic ecosystems and therefore actions taken to reduce the nutrient load to aquatic system including the Baltic Sea has high priority. There are many different sources of phosphorous and nitrogen and domestic wastewater is one contributing factor to the high load. Especially waste water from households that is not connected to municipal sewage treatment or a local small scale plant with appropriate nutrient removal efficiency is considered a problem. These types of households are quite common in rural areas in Sweden and in areas where summer houses has been converted to permanent living. Swedish legislation now permit the municipalities to decide in which areas within the municipality higher demands of the local small scale treatment facility should be met by the households (i.e.

The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.

Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

Detta examensarbete utgör resultatet av en studie på uppdrag av Volvo Cars Torslanda (VCT) i Göteborg. Syftet med studien har varit att undersöka produktflödena mellan VCT och dess leverantörer med hjälp av analyser. Dessutom utreds hur transporterna skulle kunna optimeras och vilka konsekvenser som uppstår. Beräkningar, diskussioner och analyser resulterar i rekommendationer för företaget.För att få mer kunskap om transportlogistik, produktionsekonomi och miljöpåverkan av transporter genomförs först en litteraturstudie. En granskning av nuläget beskriver hur situationen ser ut i dagsläget och ger även en detaljerad bild av flödena från leverantörer till VCT.Sex stycken flöden vars gods transporteras från leverantörer till VCT har undersökts.

To build high-rise buildings made of timber has for long been limited by national laws, due to the lack of knowledge in engineering solutions. Frame structures made of wood has for a long time been associated with major fire hazards and consequently lower safety and this connection is still being made today. The increased environmental awareness in recent years has contributed to the exploitation of indigenous building materials, including wood from our own Swedish forests and has become increasingly common. Increased knowledge about how structures behave in fire and how they can be protected in order to achieve safe timber structures has resulted in a growing interest in these structures in the construction industry. Research in the area is constantly updated and new laws allow any number of storeys in wooden buildings in Sweden as long as the performance requirements are fulfilled.The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions.

AbstractThe tests work is about the subject "synergism of steel and concrete."The construction sector is in a strong competition and the different companies in the PrefabMarket has ever tried to develop new design solutions that are efficient and environmentallyfriendly.The purpose of this report is to highlight different aspects of interaction and size up a columndimension and to examine its efficiency and load capacity as Eurocode 3 and Eurocode 4. A sizing chart that describes the relationship between the torque and normal force shouldalso be made of the interaction . .
