This report was performed in order to evaluate a new technological measure and focuses generally on a heat pump system to a HWC-washing machine. The client is Asko Appliances AB, a company well known for its environmentally friendly products. The goal of this study was to improve the energy efficiency of a washing machine by combining a heat pump device to the heater of the wash water, in order to reduce the energy consumed for heating the water. Besides reducing the energy consumption in heating the water, the washing machine was required to meet low noise and short operating time specifications. For that purpose, nine trials in three test series have been carried out.

The purpose of this essay has been to find out how adolescents from Södermöre in the municipality of Kalmar experience the central place Kalmar. It has also been the intention to make clear, whether the relation between the adolescents and the central place Kalmar could be described as a centre-periphery-relation. The basis of this essay has been interviews of all together nine adolescents.A centre-periphery-situation can according to the theory be discovered by analyzing three categories: culture, economy and politics. If the centre dominates the periphery in one of these three categories, a centre-periphery-situation exists. The theory also says that the people living in the periphery experience less kinship with the people living in the centre.The adolescents from Södermöre showed to experience the central place Kalmar in a way, that can be described in five categories: travelling mostly by bus, unfair distribution of the resources of the municipality, political equality, social equality and the awareness of the central place Kalmar as the place ?where everything is located?.When it came to economy and politics, no indications of a centre-periphery-situation were found during the interviews with the adolescents.

AbstractThe purpose with this essay has been to gain a greater understanding and clarify how an arena can create value within place marketing and development of a place brand. This will be achieved through a description of which values an arena causes in the surrounding areas and an understanding of how these values can be interpreted through the place brand. We decided to base our study according to the following two questions:1. What are the underlying reasons why there has been such a big trend with arena project?2.

The purpose of my essay is to study the current debate on public library as a meeting place in the Swedish daily press. I have examined how the meeting function is used and how it is perceived and what it might mean to the public library. Through a selection process, I chose 18 relevant newspaper articles from the year 2006 to 2012. By implementing a content analysis, three themes were distinguished; ?the meeting place as a place to reside on?, ?the meeting place as an inclusion? and ?the meeting place as a culture and activity house? I have used Andersson, Scot-Hansen and Rabers theoretical models of the library's roles for my analysis.

The sound part is mainly practical and is dependent on concepts that have been tested through measuring with a sound level meter. The design part is more theoretical and has been verified with CAD models and finite element analysis.With a sound damping hood on the compressor the sound level is reduced with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it requires thick absorbents.By changing the today?s insulation to the heat water tank to a form of polystyrene polymer insulation the weight from the heat pump above can be transferred to the stable heat water tank.

Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. Furthermore, PFASs have also been detected in drinking water, leading to raised concerns for human health, since drinking water is one of the most significant sources of PFASs for the general population. Conventional water treatment techniques have shown to be ineffective removing PFASs, highlighting the importance for further research to develop efficient removal techniques. The aim of this study was to investigate the removal efficiency of PFASs in water using two treatment techniques; granular activated carbon (GAC), type Filtrasorb 400®, and anion exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied.

The purpose of this essay is to examine how the two Swedish municipalities, Sigtuna and Nyköping, work with marketing. The study has primarily focused on how these two municipalities worked, consciously or non-consciously, with lifestyle marketing and place marketing. The research-questions that this essay wants to answer are;What is lifestyle marketing and place marketing?Do municipalities use these types of marketing, and who is this marketing directed to?How and why does municipalities use lifestyle marketing and place marketing?To answer these questions, phone interviews were conducted with several important employees within the two municipalities. The results of this study show that the different municipalities have both been using lifestyle marketing, but on different levels, in Sigtuna, it was a strategic choice, whereas in Nyköping, it evolved by itself and was not a conscious choice.

AbstractPrevious studies have shown that wild smolt have 2.5-4.5 times higher survival rate than smolt grown in culture and that starved reared smolt behave more like wild born smolt. The purpose of this project was to study whether there are differences in migration patterns and survival during migration to the coast between wild and reared smolt and between different types of reared smolt.In 2009, 25 smolts in three different groups were tagged with acoustic transmitters: Wild Born, conventionally reared 2-year and 1 ?year old smolt. For the 2010 trial there was also added a group of reared 2 ?year old smolt that were starved before release.

A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.

In this thesis I try to examine the consumtion among people that are retired and therefore can be considered as being in the third age. This studie is carried out in Norrköping, with interviews of people living in or close to Norrköping. I have used theories about the third age, consumtion and the space of the city. I have examined the importance of the city space as a meeting place and where the elderly buy the things they need for there everyday life. I also try to examine if the things they buy has an importance that goes beyond the immediate use, such as communicating a persons status to others.

Stage-discharge equations for lakes without disharge measurementsSimon AnderssonIn 2015 all lakes, rivers, coastal water and groundwater should be of good ecological statusaccording to the water framework directive from the European Union. In the process ofimproving the quality of Swedish water bodies, knowledge of where problems occur isneeded in order to utilize the resources optimally. The ability of lakes to store water is animportant factor since it controls the flow of water through the country. A stage-dischargeequation is a mathematical relation between discharge from a lake and its water level. Bybetter understanding of stage-discharge equations for lakes, their storage capacity can bedescribed better in hydrological models.This master thesis aims to evaluate methods for determining stage-discharge equations forlakes where a variable amount of field measurements is available.

This report investigates a possible solution to the problem with adapting wave powerplants to work in countries with tidal water. The wire connecting the buoy at the surface with the generator at the bottom needs to adjust to the varying water depth. Our solution to this problem is to attach the wire to a jack which is then placed inside the buoy. The jack is then powered by an electric engine. The report discuss what forces the buoy will be exposed to and then the structural integrity of the design is evaluated through simulations.
