Ökad användning av biodrivmedel i vägtransportsektorn : en styrmedelsanalys
The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010.
More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.
Sammankoppling av fjärrvärmenäten i Nyköping och Oxelösund : miljö- och systemkonsekvenser
District heating covers most of the residential areas and industries in the twoneighbouring Swedish municipalities Nyköping and Oxelösund. In Nyköping,Vattenfall AB Värme produces heat in a bio-fuelled CHP plant. In Oxelösund,waste heat and use of waste gases from the steel production at SSABOxelösund is the basis in the district heating system.This report examines the environmental consequences of a connection betweenthe two district heating systems. A broad system approach is used and the focusis on environmental effects in the system.A system analysis has been performed on the result of simulations of differentheat and electricity production alternatives. The alternatives simulated wereone where Vattenfall Nyköping covers the base load in the joint district heatingsystem and two where the power plant at SSAB Oxelösund supplies the heatbase load.The conclusion in this report is that the consequences of connecting the twodistrict heating systems can be both positive and negative, depending onsystem boundaries and on the environmental focus.
?Vi är till för kommuninvånarna? : En kvalitativ studie av musikavdelningen på Enköpings kommunbibliotek
The aim of this study is to examine the significance of having a music department at the public library in Enköping, and how the organization of the phonograms is handled. The different areas examined are the reason of the reintroduction of a music department, its budget, its users, the work with selection, the marketing, statistical data concerning loans, the work with classification, indexing, and organization of the phonograms and the future of the music department. The empirical material consists of qualitative interviews with staff connected to the music department at the public library in Enköping. For the theoretical frame, Sanna Taljas discourse analysis of music libraries in Finland is used. Talja presents three discourses which all show different views on what kind of material a music library should contain.

Sk?rselden i bilder, Makten ?ver sj?larna
This essay examines how art could be used to bring forth and clarify the Catholic doctrines of purgatory.
The research questions are:
?
How are the Catholic Church?s doctrines of purgatory illustrated in art?
?
How can the paintings affect the viewer and his/her notion on how to shorten the time in purgatory? How can art itself be used as a tool to achieve that goal?
The timeframe of the chosen paintings is mainly 14th to 16th century but an overview of how the purgatory has been illustrated after that time until the present is also given.
In order to answer the first research question, a painting from the 14th century has been analysed, using a method inspired by Patterns of Intention - a theoretical framework formulated by Michel Baxandall. A reception theoretic perspective according to Kemp, is used on a painting from the 15th century to answer the second research question.
The results show that purgatory is illustrated as fire and the souls are depicted as living people, despite that a spiritual condition is visualized. The viewers at that time found the descriptions frightening, but the paintings also revealed ways of being granted indulgences, that is shorten-ing the time in purgatory. These ways were praying, making pilgrimages and giving alms.

Masskattning av tunga fordon i realtid genom systemidentifiering
As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..
Spädningsvätskans påverkan på vaginas mikrobiologiska normalflora hos sto i samband med insemination
Sheep breeding contributes not only with wool, hides, meat and milk but also with openlandscapes. The sheep?s wool is a good raw material thanks to a lot of different qualities as itis water rejecting and easy to form. The wool production today is concentrated to specificplaces in the world which leads to environmental problems and a distorted market. InJämtland, a province in Sweden, there is right now a staking going on for local production andrefining of wool in a project called Ullforum.

Because of this, several companies have started to take interest in the effects they?re responsible for, not least considering their image. Emissions of carbon dioxide generated from goods traffic are accountable for a large part of the total emissions of greenhouse gases in the world.
Projekt Sunbaker : Utveckling av en solugn för bakning, en fältstudie i Namibia
Namibia, southern Africa, suffers from an energy shortage and is therefore facing severalchallenging problems. The use of firewood as fuel for cooking is common in the whole countryand has negative consequences for health and the environment. This work have focused ondeveloping a solar baking oven, calledSunbaker, adapted for Namibian families needs forbaking. The development was based on classic solar cooking limitations, specific needs forNamibia and to have a feasible manufacturability.The project started with a theoretical study in Sweden where different solar cookers, informationregarding Namibia, technical aspects and end user aspects were studied. To assess the need for asolar baking oven aMinor Field Study took place in Namibia during eight weeks in July toSeptember 2009 and resulted in a product design specification.
Hägn i skogsbruket :
This survey was made during the autumn of 2002 and the beginning of 2003, on commission
from the National Board of Forestry. The purpose with the survey was to gather experience
and knowledge in the organisation about fencing and this was made through interviews. The
ambition was also to get knowledge from people outside the organisation that have great
experience of forestry and fencing.
The interviews were based on questions that have been composed by the author with help
from the supervisors. The questions were the same to both the personal from the National
Board of Forestry and to the foresters. Interviews were also made with private landowners, gamekeepers, game researcher, the County Administrative Board, the National Road Administration, pole and net retailers and contractors.
The target group for this work is the National Board of Forestry to be forwarded to persons interested in forestry with the ambition to spread knowledge about how to prevent damage on the forest by browsing animals.
The deer populations are big in the south of Sweden and growing populations have increased the damage on plantations of broadleaves of the most species.

Faktorer som påverkade valet : En studie i blivande sjöingenjörers utbildningsval
Den svenska handelsflottan har de senaste åren varit utsatt för massiva utflaggningar vilket har lett till att många sjömän har fått gå i land eller sökt arbete under annan flagg. Trots problemen med utflaggning och en potentiell minskad arbetsmarknad har sjöingenjörsprogrammet de senaste åren inte haft några större problem att fylla sina utbildningsplatser. Framtiden är fortsatt oviss och konkurrensen från andra sjöfartsnationer ökar. Syftet med denna undersökning var att undersöka vilka bakomliggande attityder och förväntningar som gjorde att studenter år 2013 valde att börja studera på det fyra åriga sjöingenjörsprogrammet i Kalmar, samt att mäta inställningen till den allt mer krympande svenska handelsflottan. För att genomföra detta arbete användes en enkätundersökning där förstaårsstudenterna på det fyraåriga sjöingenjörsprogrammet utgjorde populationen.
Nordiska sjömäns arbetsutsikter inom offshorebranschen : Vad händer när olje- och gasreserverna i Nordsjön tar slut?
AbstractThis thesis is a qualitative study that provides an insight into the Nordic offshore market, focusing on the North Sea and investigates indications of how the near future may develop in the area and how these developments may affect the Nordic seafarers. Questions central to the work are aimed primarily at how shipping companies, agencies and seafarers active in the offshore industry look at future activity in the North Sea, Nordic seafarers' status in the global labor market, and how today's employment conditions look like for seafarers in the global offshore industry. The majority of the information was collected through interviewes and questionnaires. The purpose of this study was to examine whether and how the expected development in the North Sea, in terms of availability of oil and gas, may have effect on the Scandinavian seafarers' future work prospects and employment conditions in the global offshore labor. The conclusions that have been drawn are that competition among seafarers in the offshore industry is higher 2015 than previous years (2000-2014) and are expected to increase.
