The tribo system ice-curling stone was investigated in order to understand the mechanisms behind the stones' behavior on the ice sheet. The problem with non-identical stones should also be addressed.The stone curls, that is, its sliding path deviates from a straight line to the right for a clock-wise rotation and to the left for a anti-clock-wise rotation. Several mechanisms to explain this behavior have been proposed over the years but none has been successful.By carrying out experiments at the local curling rink and studying silicon castings of ice- and stone-surfaces with scanning electron microscopy and vertical scanning interferometry, it has been decided that the curl is not due to dry friction, ice-debris or the difference in friction on the left and right side of the stone. The side force comes from the fact that the friction is higher at the back of the stone than at the front.The contact between stone and ice is never completely dry, nor in the hydrodynamic lubrication regime. It is probably a combination of hydrodynamic lubrication and a contribution from mechanical scratching of the ice.

In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials. The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.

The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

Denna studie handlar om den fartförlust och därmed den ökade energiförbrukningen som drabbar fartyg på grunt vatten. Syftet var att ta reda på hur mycket kortare en grund passage behöver vara för att den ska vara ett bättre alternativ än en lång och djup rutt med hänsyn till bränsleförbrukning och tidsåtgång. Resultatet av detta blev att det inte går att dra några generella slutsatser som gäller för alla fartygstyper men att det går att se tydliga tendenser. Studien hade även som målsättning att skapa ett underlag som skulle kunna användas av nautiker vid planering av resor, detta presenterades i form av en sammanställning av de resultat som erhållits vid beräkning av fartförlust i öppet vatten. Någon sammanställning gjordes inte för begränsat vatten eftersom exempelfartygen där fick likadana resultat vilket skulle ha gjort en sådan överflödig.

Background: It has been shown that EDI can yield positive effects within companies. Which effects are possible for a company to direct assign to the introduction of EDI and is it possible to estimate the total effect.Purpose: The purpose of this study is to estimate and analyze the effects of using EDI in electronic business. We also want to contribute with a model for measure and estimate the effects of EDI.Accomplishment: We have studied literature concering EDI and realized a preliminary studie in form of interviews with experts to establish deeper knowledge of EDI. We have also tried to estimate the effects obtained in companies in three different businesses, power, government and transport industry.Result: To obtain as good effects as possible it is important that the co- oporation is built on trust and engagement. Before implementing the EDI-system a thorough overhaul of the processes in the company should be done, involving both the top managers and the staff.

In family firms altruistic effects can arise in order to preserve the ownership of the firm within the family. The family firm may chose to carry or take measures against these effects. Regardless, it will lead to different agent costs. Therefore, the aims of the study were to explain how altruistic effects in family firms exert an influence on the administrative systems and possible counter measures.In order to explain the origin of altruistic effects, we built a theory which showed that the altruistic effects were followed by agent costs. The family can take measures to counteract these original effects.

Car-commercials are something that many people come in contact with on a daily basis.This is a study on commercials for cars and is focusing on visual effects that are madein post-production. In this report we are trying to find out if and how visual effects incommercials for cars affect how the observer remembers them. The second subjects thatwe use in this report is popularity and we try to find out if and in that case how visualeffects affect the commercials for cars popularity. We also investigated how frequentlycommercials for cars are showed on TV and how the visual effects are in them, it givesa better foundation to the other parts.The methods we applied were interviews, quantitative and qualitative content analysisof car commercials and also observation analysis of the 6 swedish TV-channels thatshows commercials and have the most viewers, to get an idea how frequently thesecommercials are shown. The commercials that were applied in this paper was from late2011 to early 2012.

The presence of nostalgic emotions during consumption is often seen as something purely positive to a product. To evoke these emotions has become a very common tool in marketing and advertising. Paradoxically very few studies have focused on the effects of nostalgia. The purpose of the thesis has been to understand how the presence of nostalgic emotions during consumption effect consumers. The research model used is a quantitative study with testing of hypotheses generated from theory.

Social intranets are based on the Enterprise 2.0 expression and create a new way for organizations to communicate and work. It brings possibilities to leverage user generated content and engage in cooperation across organizational borders where users can get to know each other and share knowledge.This thesis aims to explore what expectations motivate decision makers in implementing social intranets. It is interesting to discover what is expected to happen in an organization that implements a social intranet and chiefly what the actual effects are. Through interviews of both management executives and intranet users at a consulting company called Ninetech, we have plotted out managers? expectations and effects experienced by users.We have categorized managements? expected effects in two themes; expected effects on corporate culture and expected effects on informational work.

Consumers today are bombarded with innumerable advertising messages. The need for companies to create advertisements that consumers find relevant is thus increasing. In order to break through the ad clutter, companies have to give something extra to their customers and show that they care about them. How a company decides to communicate might then be more important than what the company actually communicates.The purpose of this paper is to investigate whether the use of creative media choices induces signaling effects and enhances advertising value as well as perceived corporate consideration. The two last mentioned variables are explored as potential driving forces behind the signaling effects.

Objective: To study midwives management, practice and reasoning regarding contraceptive counseling for women who are experiencing "mild" side effects of the pillMethods: Four focus groups, made up of three to five midwives per group, participated in focus group discussions. Qualitative design with the method ?Think-Aloud? has been used to collect data and the material was analyzed using content analysis.Results: The study identified three categories, the first "How midwives practice regarding the side effects of the pill," shows that midwives have a systematic approach when meeting with women who are experiencing side effects of the pill. The next category "Using a holistic and professional approach for women" highlights that the midwives take women's side effects seriously and that midwives respect individual woman?s autonomy.

This bachelor thesis aims to analyse the effects of changes in management control systems following acquisitions, and deduce whether or not these effects are in line with the acquiring firm's objectives of the acquisition. Through a case study of technician consultant firm Energo, acquired in 2010 by ÅF, the study assumes the perspective of the acquired firm. Data has been collected through in-depth interviews at Energo and ÅF and complemented by internal documents to enrich and validate specific facts and statements. Data was then arranged and analysed through Otley and Fierriera's (2009) framework Performance Management Systems to understand how management control systems were constituted before the acquisition, what changes were made following the acquisition, how this process was accomplished and how it was experienced, in order to come to conclusions about the effects of these changes. The study concludes that the changes in Energo's management control system following the integration with ÅF, had significant effects on the outcome of the acquisition, primarily as it led to a high rate of Energo's employees resigning.

The purpose of this dissertation is to describe and analyse the effects of tourism in developing countries and the attitudes and working methods of Swedish tour operators towards sustainable tourism. We have chosen to use a qualitative research according to a hermeneutical view. We have carried through in-depth interviews with eight tour operators. The theories have been divided into the effects of tourism and sustainable tourism goals which have social, economic and environmental starting points. The empiricism describes the work and activities of the tour operators and compiles the interview material divided into attitudes on tourism effects and responsibilities.

The function of budgetary controls is to control the resource allocation within companies. It can also be an instrument for measure and control subordinates and/or business units? performance (Van der Stede 2001). This paper concerns the latter; when the budgetary control function is used to measure and control subordinates performance based on budget. Previous research in this area has not yet accomplished to explain the effects of tight budgetary control which Hartman (2000) considers as the main issue to be concerned about in management accounting research.Previous research has presented contradictory findings regarding tight budgetary control explained by positive effects as well as negative effects during the last decades.
