When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

The aim of this thesis is to examine how salesperson control can be exercised in a retail store environment. A case study has been performed on a Swedish fashion company emphasizing the relationship between the company?s upper level management and their retail store operations in order to describe, analyze and classify the prevailing management control mechanisms. The paper presents an agency theoretical approach to the relationship applying behavior- and outcome based control theory, performance measurement theory and incentives theory in order to give a comprehensive image of the control system. The main finding is that the company?s management control system as applied to the sales force in its retail stores can be categorized as mainly behavior-based despite several explicit outcome-based features..

Until the sixties potatoes have had a unthreatened position at the Swedish dining tables, but then different alternatives such as rice and pasta have become popular. In 2005 the Swedish potato-consumption have more than hafted compared with the sixties, we have gone from circa 90 to 40 kilograms per person and year. This paper aims to provide those who are involved within the potatoe business with an overview of the attitude and behaviour towards potatoes that are being held by Swedish consumers. In order to reach to the conclusion, in- store interviews had been held with customers in the cities of Stockholm and Malmö. The interviews showed that the typical potato-consumer prefers to choose and in pick their own potatoes to a bag in the store in favour of the pre-packed alternatives. Based on the outcome of the interviews a number of conclusions could be drawn. The consumers were of the perception that the pre-packed alternatives were too big for their households.

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.

Internal communication is very important for the success of an organization. The county council Landstinget i Värmland is a large organization with many managers on different positions. Every one of these managers gets an email every week, with the message that a new manager letter, called Chef, is published on the intranet. With my paper I am examining what the managers think of this letter, how they use it and if managers on different positions differ from each other in opinions about and use of the letter. I want to find out if there is a need of Chef as a part of the internal communication of Landstinget i Värmland.To answer these questions, I have chosen a quantitative method in the form of a questionnaire which is send to all the receivers of the manager letter.

The purpose of this thesis is to increase the understanding on how market leading pharmaceutical companies in Sweden limit the market share decrease when these companies patent expires. In order to respond to the purpose, two research questions have been asked: how do pharmaceutical companies deal with market strategies prior to the expiration of a patent: and how the market strategies is used when a patent has expired and as a consequence, generics entered the market. A case study was implemented based on two interviews with a brand manager and a therapy area manager within the company Pfizer AB in Sweden. The results suggest that pharmaceutical companies implement strategies in numerous ways which differs substantially from the theories, this having to do with Swedish legislation. The main aim with the execution of the strategy, before and after patent expiration is not to limit a decrease in market share hence, rather to retain the pharmaceutical companies strong brand image.

Communication is essential for the survival of an organization. The management formulates strategies to ensure thatthe organization will get to where they want it to go. The strategy is then communicated to the co-workers through the line manager.

Under det senaste decenniet har den svenska elektronikhandeln präglats av en allt hårdare konkurrenssituation och lägre lönsamhet. Det har lett till att stora butikskedjor gått i konkurs. För att vända trenden måste företagen hanterar sina butiksverksamheter effektivt. Det blir därmed avgörande hur butikschefen sköter butiken. Av den anledningen är det intressant att underso?ka butikschefers arbetssätt för att se vad som leder till hög lönsamhet.

ABSTRACTThe purpose of this c-level essay shall try to illustrate how a good leader is formed. We have investigated what influences leadership style, personal characteristics or individual competence have when recruiting a new manager. This study has been carried out with comparative applications because we wanted to study the similarities and differences between the Unemployment Office, the Social Insurance Office and the Social Welfare Administration.We have used a qualitative method in interviews both with employers as well as the from the trade union representative?s perspective. Part of our results indicates that the trade union representatives and the employers are not always unanimous and do not request equivalent characteristics and knowledge at recruitment.

Purpose/Aim: The purpose of this thesis is to study the interaction between seller and buyer in a mobile phone store. The specific research questions under investigation are:Are there any underlying factors behind mobile purchase, and if so, what are they? Are mobile purchases driven by lifestyle factors and do customers try and create identities when purchasing new mobile phones?Material/Method: The study employs an ethnographic method when trying to answer the posed research questions.
