Forces of innovation alter the course of many industries. Currently there is a restructuring of the Swedish energy sector due to deregulation. This in combination with advanced technologies generates an innovative and a highly changeable environment. The result is differentiation of services and products. New actors are emerging and corporations grow larger.

Biogas is a gaseous fuel, rich in methane, produced through a biological route in an anaerobic digester. A gas engine generates combined heat and power, which can be used at the farm to reduce energy cost. The process also generates a digestate, with better utilization of nutrient compared to cattle manure. The aim of this study is to analyze the profitability of a farm-scale biogas plant for combined heat and power (CHP) at Wapnö. Wapnö is an agriculture company located in the southern part of Sweden.

The present climate discussion has made energy efficiency an interesting topic. Saving energy does not only help the climate but also saves money for the energy consumer. The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two milk farms, one with voluntary milking system, VMS, and the other with conventional milking system was used to measure interesting temperatures and electricity consumptions. The numbers were used both to do theoretical calculations and to construct a SIMULINK model. To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using a reference farm with different combinations of heat recovery and pre cooling. The farm was assumed to keep a dwelling house with the annual heat consumption 18165 kWh.

The aim of the study was to illustrate how care managers reflect and act in regards to self-determination and integrity when caring for residents over 65 years old who have a dementia diagnosis. Our main questions dealt with how care managers handle the right to self-determination and integrity when a person has dementia, to which extent the care managers listen to the person with dementia and how the care managers look upon the residents with dementia?s ability of self-determination. To find the answers to our questions, we interviewed ten care managers within the elderly care in Gothenburg, Sweden. We used qualitative interviews based on a semi-structured interview guide.

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

AbstractIn the literature on multiculturalism and group rights there is a strong tradition that sees diversity as something directly paradoxal to unity. In this tradition, scholars put forward a view of multiculturalism as a divisive and exclusionary process which breaks down the cohesion and unity of society. Related to this notion is that of a neutral and universally valid frame of reference in which political dilemmas can be solved; for example a neutral civil sphere where the ?true essence? of society lies. In this essay I attempt to criticise these two notions.

The fishing port of Bläsinge is located on the east coast of Öland, Sweden?s second largest island. Today the port has a limited supply of freshwater. The economic association of the fishing port wants to expand their business, so that they will also include tourist services. To do this the harbor will need a more independant source of freshwater, with a higher quality than the present well.

Currently there is a controversial debate about that we must reduce our impact on the global warming; therefore both the Government and the local authorities have invested heavily in developing renewable energy in Sweden. The major development on the wind power market can be seen as a result of both the technological development and also on the decision that the Government took in 1996, which opened up the wind power market for private parties.This paper has aimed to examine the types of financial innovations that have arisen from the investments and financing of wind power on Gotland, and what these innovations can contribute to the future development of wind power.The problems that this thesis is based on is; what kind of financial innovations have occurred within investment and financing of wind power? How can these innovations contribute to the continued development of wind power on Gotland? The conclusion of this study shows that respondents and participants have defined a number of financial innovations that have emerged. Where some of the innovations only can be seen as incremental since they are based on continuous improvements, while others can be seen as radical as they are completely new for the context in which they operate. The study has also shown that Gotland has a great potential to produce more renewable electricity, but the development is dependent on the new power lines being built, in order to export electricity to the mainland..

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.

In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.

Denna studie görs inom det arbetslivspedagogiska fältet och behandlar arbetsrotation på ICA-butiker. Syftet är att undersöka hur arbetsrotation sker hos medarbetare inom olika ICA-butiker och vilken betydelse det får för lärandet. Lärandet som undersöks är hur individer kan tillgodogöra sig yrkeskunskap utifrån de läroprocesser och lärandesituationer som uppstår i samband med arbetsrotation.De teoretiska verktyg som används grundar sig i Ellströms feed-forward och feed-back faser, de tre regleringsnivåerna av lärande samt en teori om subjektiva och objektiva handlingsutrymmen. Studien använder sig även av Börnfelts teori om en formell och informell organisation.Den metod som använts är kvalitativ och grundar sig i öppna intervjuer med åtta anställda från ICA-butiker med olika butiksformat, med det syftar vi till ICAs butiksformat; Nära, Supermarket, Kvantum och Maxi. Intervjuerna har transkriberats och analyserats ner till fyra olika teman; Arbetets innehåll, Avvikande situationer, Formellt Medarbetarskap och Informella Relationer.Resultatet visar att om anställda roterar mellan avdelningar eller ställs inför utmaning öppnar det upp individers handlingsutrymme, vilket leder till feed-forward faser som i sig genererar lärosituationer där anställda kan lära sig på en begreppslig- och intellektuell nivå.

Göteborg Energi has a surplus of district heating during spring, summer and fall. The heat surplus is due to a constant production of waste heat from oil refineries and heat from waste incineration over the year. It would be desirable to increase the demand for heat and the uptime for the newly built combined heat and power generation plant, Rya Kraftvärmeverk. One alternative could be to integrate Rya Kraftvärmeverk with a pellet production facility. By producing heat, electricity and pellet in a joint process the energy use can be decreased.

The purpose of this thesis is to outline an appropriate model in order for companies to successfully act and compete physically as wholesalers at the same time as acting on the virtual market by selling directly to the end consumer. The approach of this thesis is hermeneutical and abductive with elements of hypothetically deductive approach. Our research has a qualitative research strategy based on case studies and interviews as well as on secondary data. Interviews were conducted with the case company JaymJay Wear AB as well as with other companies, so called mini cases. The secondary data consists mainly of textbooks, web sites and journals.

A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.

The aim of the study is to investigate the relationship between text and picture in two works by Sven Nordqvist, with the focus on how the action is propelled. The two works are compared in order to bring out any differences in the relationship and what significance this can have for the interpretation. The study also considers the theory of conceptual worlds to examine how the books can promote pupils? literary understanding. The method of analysis is based on Rhedin?s (2001) theoretical concepts and elements of Nikolajeva?s (2000) terminology.
