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.

We have chosen to focus this paper on the importance of game-components in the MMORPG-game World of Warcraft, in order to discover which of them who are the most important and create the biggest motivation to play the game for the players of World of Warcraft. We made this  investigation because we wanted to find out more about the specific reasons about what people think is especially great with World of Warcraft and makes them want to play it for hour after hour. By doing this we wanted to find out what it is that is so appreciated with this game. But this is a big area and it has therefore been difficult to find a way to satisfy and make those who have answered on our survey to feel that the game-component they enjoy most has been a part of our questions.To solve this problem we did a survey that included 200 persons and two interviews. When both the survey and the interviews had been completed, the result was being compared against each other and together to see if there was any difference between them or if they had any similarity to the attraction and motivation.

Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

Vattenfall Heat Uppsala runs the waste incineration plant in Uppsala, which produces district heating, process steam, district cooling and electricity. Vattenfall Heat Uppsala has decided to introduce an energy management system with the aim to increase the energy efficiency of the plant. The basis in such a system is to make an energy mapping.In this thesis an energy mapping has been performed at the waste incineration plant with the aim to identify and determine the size of energy flows. The investigated energy flows are used fuel, produced and used steam, produced district heating and cooling. Also the use of electricity to run the processes has been investigated.

The research on Ingmar Bergman is comprehensive, however, there is one aspect of his artistry that has been regrettably neglected ? his use of music. Music always played a huge part in Bergman?s life, and it was also a great source of inspiration. The music was a structural component in the creating process and he often referred to his films as pieces of music and his actors as musical instruments.

This paper aims to study the Armenakis´ theory of readiness, "are they ready?", which consists of five key components affecting the outcome of an organizational change. In this case study, the intention is to investigate if any component is important; alternatively if it is possible to discern a pattern between components, i.e. how they correspond to each other. During the past 30 years have a research group lead by Armenakis has studied organizational change and how resistance to change can be avoided by preparing employees in the introductory phase of change. The main object for Armenakis is the question "what determines whether the employees (change recipients) adopt and support, or reject and resist a change".

Background: Relatives are those persons who are closest to the patient, regardless of relationship and included into the patient´s life world. When a person is in a palliative stage this affects not only the patient but also the relatives, as it implies such a big change in life for all. The nurse has an important role for both the patient and the relatives. Aim: The aim is to highlight the relative´s needs of support for palliative care. Method: A literature review based on previous research. Ten articles were found, nine with a qualitative approach and one with both qualitative and quantitative approach. Results: The analysis resulted in six themes, these were the result of the study. The six themes were, ?to be seen an confirmed?, ?good communication?, ?continuous information?, ?availability and continuity?, ?to participate? and ?to share responsibility with the staff?. Conclusion: As a nurse we come in contact with relatives of patients in a palliative setting in any form.

To the sewer systems households, industries and other activities are connected. The wastewater is collected at treatment plants where a nutritious sludge is produced. The sludge does not only contain nutrients, but also hazardous substances originating from different activities in society. To reduce the flow of hazardous substances to treatment plants and to create a sustainable recycling of plant nutrients the Swedish Water & Wastewater Association has developed the certificate system REVAQ. This certificate requires a good quality of the sludge but also that the treatment plants maps the origin of the unwanted substances.

Första januari år 2013 trädde den senaste versionen av MARPOL Annex V i kraft. Denna studie har genom en litteraturstudie samt intervjuer med nautiska befäl sökt svar på vilka förändringar som skedde, hur dem implementerats ombord samt hur förändringarna upplevts av sjöfarare. Syftet med studien var att bidra med en pusselbit till bilden av hur avfallssortering utövas till sjöss samt hur arbetet med det upplevs. Litteraturstudien kom fram till att den stora skillnaden är att papper, glas, metall samt aska inte längre får slängas i havet. Inom specialområde får endast matavfall destruerat genom avfallskvarn slängas överbord.

AbstractOur purpose for making this study is to study the implementation, the use of and the effects of Lean within our case objects.  We chose to make this thesis by case studies. The three themes mentioned above is also the main research questions that we aim to find an answer to by this study. We have chosen to do a cross section analysis where we conducted structured interviews to find answers to these questions. The theoretical reference frame consists partly of traditional theoreticians within Lean but also more recent research within the subject as well as theory specifically for Lean within the Health Care sector.The result of this study shows in all our case studies that the Management has been supporting the implementation, but that the implementation process proceeds faster if also the professionals are involved in the process.  To succeed with the implementation there is a great need for good reasons and strives that can benefit the professionals. By the use of Lean our case studies have evaluated its processes, with the main intentions being to reduce waste activities and to create flows with ?pull systems?.

The aim of the study was to map the extent of Fe, Cu, Pb, As, Zn and S contamination in the area surrounding the Nasa silver mine. The mine operated between 1635 and 1810 with some prospecting performed in 1889, and has become infamous for the gruesome ways that the indigenous people were treated during the early years of operation. This study tested three hypotheses through a geochemical survey: 1) sulfide oxidation is still active in the abandoned mine, 2) the soil downslope of the mine is contaminated by mine drainage, and 3) the stream downslope of the mine is affected in the same way. All three hypotheses were valid, as the results showed that still, >200 years after mining operations ceased, signs of the historical mining are clearly visible in the surrounding environment. Acidic conditions were discovered in surface waters close to the waste rock piles, which indicates active sulfide oxidation.

Treatment wetlands been showed efficient for reducing pollutant in waste water. In Lajeado ? RS, Brazil the landfill has poor leachate water treatment. It is necessary to supplement the treatment plant because they need to reduce BOD, COD and nitrate of the water going to recipient. A subsurface flow wetland (SSF) can be a good choice.  In order to be able to design an efficient SSF it is important to understand how the grain sizes of a substrate affect the reducing of pollutants in waste water.

Title: Employee experience of psychosocial working environment during change at the workplace.In times of change processes the working environment at the workplace may be affected. Lack of balance between demands and the ability to handle the workload can lead to reduced work satisfaction, which is an important component for an individual?s performance and commitment. The aim is to investigate experiences in the employee?s psychosocial working environment during change management.

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.
