In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

Environmental issues is now taking a growing place in society and to ensure that companies meet public expectations and do their part in working towards a sustainable development, environmental management system is said to be an effective tool (Almgren & Brorson, 2009).This case study has examined a company's environmental management system in order to find strengths and weaknesses within the ISO 14001 system. The work was carried out using interviews, document reviews and analyzes in which the three main concepts control the report ; "daily work", "audit" and "environmental aspects".The results shows that the daily work looks different depending on where you are; in the production or at the office. The audit examined all documents related to the environmental management system and the study showed that the biggest strengths was the commitment and waste handling while areas such as environmental goals and management review needed improvement. As a result of the deficiencies identified, suggestions for improvements was proposed. The investigation of the routine of the environmental aspects showed an incomplete routine where the red wire from identification to evaluation was missing.

This paper focuses on how young people use and are affected by Facebook. The study embodies students from the social work program in Sweden and their view on Facebook use. Earlier research has shown that Facebook use has increased among youths. At the same time research tells us that social interaction plays an important part in shaping our identity. It is from those stands that we base this paper on, and explore our interview persons answer after the theories of Erving Goffman and the people who have studied him, such as Bernie Hogan and Zeynep Tufekci.

This study explores the different effects on attitude and behaviour three frequently used advertising techniques have. The techniques compared are social influence and egoistic and altruistic benefit-appeals. The results showed that ads featuring social influence had statistically significant higher mean values regarding attitude towards the ad compared to both the other ads, and significantly higher mean values regarding brand attitude compared to the ad appealing to egoistic motivations. Though, all advertising effectiveness measures used in this study - that is, attitude and intention variables - indicated that social influence was more effective than the other advertising messages. Thus, in accord with earlier studies, it can be stated with confidence that social influence is an effective tool to use in marketing communications..

The purpose with our study is to investigate in which way a public field of action has succeeded to make the economic management more effective and also find out which factors/activities that have contributed to get the result of the budget in balance. We also want to find out in which degree the balanced scorecard (BSC) has contributed to the positive result of the budget. Method: We had started out from the qualitative method theory which is based on the hermeneutic theory, because we will interpret and understand. With this starting point we have chosen to use a case study with semi-standardised interviews supplemented with information from different documents, and to get the theoretic connection we have studied literature in the subject field. The analyse and even the theoretic connection have then started from, for this study, a special analyse model. Results: Througt systematic and target-concentrated management and through cooperated factors, with stress on a leadership that is both professional, visionary and un-combined, and there the staff´s is seen as a important resource, and there it is a clear strategy and objective to keep the cost of the activity within assigned budgetframe, has a public field of action, as the clinic of hab./rehab.

THE CONSTANT IMPROVAL AND REFINEMENT OF THE MOBILE TECHNOLOGY HAVE MADE IT POSSIBLEto use video in settings where such use couldn't be motivated before, due to economicaland practical reasons. The purpose of the study was to identify and explore possiblechallenges in interorganizational use of video during emergency response work. Thiswas done by a case study of a system designed for the use of video in such situations.The study focused on operational challenges for the fire and rescue services and thehealthcare organisations, where the main challenges identified were intended to beanalysed and discussed in terms of design. The empirical results were gathered throughqualitative interviews with representatives from the fire and rescue services and thehealthcare organisations in Göteborg. This material made it clear that contextual aspectsof emergency response work lead to a couple of challenges connected to the use of videoin such situations.

In cooperate with Asko Cylinda we have developed a new heat system too short the processtime and reduce the energy consume in a dishwasher and still have it too be a class AAA.The environment and quality is important for the company too still be the number one onthe market, If they want too keep that position the product developed of new innovations willbe very important. The systems we have developed are more effective and reduce energy uptoo 25 %. The process time is reduced too less than two hours, from the today two andhalf-hour. The solutions are too heat up the rinse water and the dishwater at the same time,with a new heating system and it make are solutions unique and effective. Its good for thedish and the environment.

AbstractAs a young offender in Sweden today you can be sentenced to juvenile care within the social services. Within the juvenile care it may be an option for these young offenders to undergo an affect program. That is a collective name for several types of structured programs that can include everything from conversations to visits. The purpose of this study was to create an understanding of which arguments there are for why these affect programs for young offenders is being used in three municipalities in southern Sweden. We authors found this interesting because of the lack of evidence for these affect programs.

Schizophrenia can cause symptoms such as auditory hallucinations, delusions, emotional blunting, apathy and lack of motivation.

Furthermore guidance regarding the utility of the interventions will be given based on the author?s assessment of the evidence in the 22 articles included.

The aim of the study was to explore the methods used in horticultural therapy gardens in rehabilitating people suffering from fatigue syndrome. Nine horticultural therapy gardens were contacted of wich three chose to participate. Using case study as method e-mail interviews was carried out with the participants about their establishment and what kind of theories they based their methods upon. The material collected from the interviews was complemented with additional data from the establishments web pages and information pamphlets. Collected data was processed trough content analysis and then formed as background for the development of a program theory for horticultural therapy.

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

AbstractThis study examines how knowledge transfer works within the student nations of Uppsala. The purpose is to describe and analyze how the knowledge is transferred when the officials are being exchanged within the student nation. Furthermore the purpose is to explore if the student nations work active to preserve the knowledge and how it is done in such case. Eight out of Uppsalas thirteen nations are part of the study and the survey was conducted by qualitative interview. The study mainly assumes from Argotes theories on the organizational memory, Davenport and Prusaks theories on knowledge transfer and Nonaka and Konnos SECI-model. The study reveals that the student nations work in different ways and more and less active with knowledge transfer.
