Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

There is a clear difference between the way football players and leaders regard the role of the referee, compared to the way the refereeing body looks at it. The refereeing body regard themselves as fundamental for the existence of the sport, while the other mentioned parties merely see them as functional justice makers. This view places the referees outside the field of football. This establishes a football culture, which is conflicted when it comes to the role of the referees on the field. The conflict comes to its edge in youth football, where the referees are under severe pressure.

The so called ?ByggaF-method? is a relatively new Swedish method to stop moisture from being built into a building. The method should prevent damages on buildings as a result of mould growth and moisture. The purpose of the method is to include moisture control in the entire constructionprocess, from the projecting phase and all the way to the management phase. Up until now, there is no proof if the method is profitable or not and no studies have been made on the topic.

Syftet med uppsatsen är att jämföra hur grunderna för ansvarsfrihet från skadestånd vid fullgörelsehinder är uppbyggda i olika normsystem för att utifrån en komparativ analys komma fram till vilket system som är bäst tillämpbart i en situation liknande den i scenariot med den försenade vaccinleveransen som jag beskrivit i inledningen till uppsatsen.De regler jag valt att studera för en komparativ jämförelse är kontrollansvaret i den svenska köplagen 27 § och CISG art. 79, modellagarna PECL och Unidroit Principles regler om force majeure och hardship, standardklausulerna i ICC 2003 Force Majeure and Hardship Clauses samt den engelska läran om frustration. Att jag valt att studera teorin om hardship beror på att teorin är starkt sammankopplad till reglerna om force majeure och kontrollansvar. Jag har valt PECL och UNIDROIT som exempel på hur modellagar kan vara upplagda. Fler modellagar och principer finns.

This master essay is about teenagers, alcohol and the preventing measures taken by the Swedish government. Consequences of the rising consumption of alcohol among adolescents and how to prevent dangerous alcohol consumption in the future is one of the most prioritized issues in the Swedish society today. Today there is no prevention that clearly shows any effect on teenager?s alcohol consumption and the education about the dangerous effect of alcohol is clearly not the same in schools around Sweden. To gain knowledge about how teenagers view their own consumption of alcohol we have used the Grounded Theory.

This work examines the students´ thoughts on climate change with a focus on carbondioxid through photosynthesis and the carbon emissions from cars. The study is based on two subject areas, one with a focus on enhanced greenhouse effect, and the other focusing on photosythesis. The survey was conducted by means of qualitative interviews with students in grades four and six. The results describe that student´s understanding for photosynthesis and the carbondioxids function for photosynthesis doesn´t change significantly from grade four to grade six. I have divided the students inte three levels based on their understandingof the various fields, and their use of adequate concepts.

The main purpose of this thesis is to analyze why or why not Swedish municipalities implement the gender equality policy ? ?right to work fulltime?. In order to understand this institutional change, the analysis is based on a theoretical framework consisting of two fields: political representation and feminist institutionalism. The study is divided into two empirical inquiries. The first part is based on a quantitative survey that describes the casual relationship between two independent variables; women´s political representation and party ideology, and the dependent variable; political decision about ?right to work fulltime?.

Företag idag söker ständigt nya och förbättrade konkurrensfördelar, som är en konsekvens av den snabba och ökande globaliseringstrenden. Ett viktigt grundincitament för att skapa dessa fördelar samt bemöta omvärldens föränderlighet och krav har bidragit till att allt större fokus riktats mot behovet av en bred kompetens, det vill säga ett utvecklat humankapital, inom företag. Humankapitalet är en av de mest betydelsefulla grundpelarna i ett företag då företaget är beroende av de anställdas kompetens och innovationsförmåga. Det är således viktigt att ett företag styr humankapitalet på ett sådant sätt att det når en stärkande eller förädlande effekt. Ett sätt för att strategiskt styra förädlingsprocessen av humankapitalet är att nyttja Simons Levers of Control, vilken även går under benämningen Simons styrmodell.

The swedish healthcare is in many situations one of the best in the world. But still, the healthcare system includes elemnts that reduce the efficiency. Partly becouse the swedish healthcare is largely monopolized, the servicecs are not properly prized and the economic responsibility and the liability legislation is limited. The main problem this study evolves around, is how a different liability rule would change the shape of the healthcare organisation. Abouve all, how would the approach to riskmanagement and preventive and riskreducing performance change with a diffrent liability rule.

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

This study is based on an inductive approach where the collected empirical data has been categorized in themes on which we have based the discussion in this paper. Using a qualitative method, nine appropriately selected respondents were questioned with an unstructured interview guide. The transition to a society characterized by interaction has caused a greater part for bilateral communication between consumer and consumer but also between consumer and company. The increased usage and integration on Internet has resulted in so called social media channels. User generated material is published on these media channels which leads to discussions about companies, products and services.

This thesis is composed within the framework of the supplementary course in psychotherapy concentrating on family therapy (60 credits) arranged by Lund University's affiliate in Västerås, Sweden.The purpose of this thesis has been to explore how the idea to initiate evidence based methods in the workings of the Individual and Family Care Department of the City of Västerås was born. Furthermore the thesis will explore if consideration for methods of theoretical implementation are implied. The study assumes a qualitative attempt and is based on semi-structured interviews from three levels within the organization, including both management and operation.Theories on organization,implementation and the theory on change strategies have been used as a theoretical starting point.The study result shows that introduction of evidence based methods in the City of Västerås is based on the experiences of the organization regarding the need to develop and increase social services contributions to non-institutional care. Experiences from expensive transferrals to institutions which only occasionally produced satisfactory results were a contributing factor. New published research and a strong interest and desire inside the department to improve and change social services contributions have naturally been a positive influence for the development.

The point of departure for this thesis was an article written by Christer Hermansson (2008). He thinks that librarians, following the development of Library 2.0 and the change of public libraries, have strayed away from what he believes should be the focus of the library: Literature. The aim of this thesis is to study how librarians in six Swedish libraries perceive their occupational roles. How does the increased user control, which is seen as part of Library 2.0, affect the tasks of libraries and librarians? The material used in this study was acquired using a qualitative interview technique in which six librarians working in public libraries with experience of IT, mediation and purchase of literature partook.

This report is a description of a developed educational simulator over rail vehicles and its components. The simulator is a hardware-based prototype over a door system on rail vehi- cles. System specialists and technicians will use the prototype. The Simulator should give the user a technical demonstration on how components work in a door system. The proto- type consists of motor, switch, relay and sensor.
