Svenska vindkraftverk till Storbritannien

This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

Termisk hantering av litium-jon- batterier i elektriska drivsystem

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

Aim: The aim of this literature review was to investigate what influence Tai Chi has on the risk for falling among elder. Method: A literature review was conducted where eleven scientific articles were analysed with inspiration of the content analysis.

Vattenlek i förskolan : Möjligheter till fysik i förskolan

The purpose of this study is to investigate witch knowledge and thoughts children will have about the term of floating and sinking, and witch possibilities there is to make various knowledge visible in preschool physics through playing with water. The study also concern the differences and similarities between two different groups of age who have participated in the study. The study was carried out by an activity with participant observation and feedback interviews afterwards. The result shows that the possibilities to physics are many in preschool. The children expressed new thoughts and ideas who concern other phenomena in physics during the investigation and discussed similar experiments and material to examine.

Att optimera för målgruppen : Processen att skapa en målgruppsanpassad landningssida för Rebtel

Företaget Rebtel ville ha en ny landningssida som riktade sig till internationella studenter. Denna sida skulle vara optimerad för målgruppen både gällande design och innehåll. En förundersökningen bestående av bland annat intervjuer med målgruppen, målgruppsanalyser och research gjordes därför. Förundersökningen bestod också av intervjuer med olika roller på företaget Rebtel för att få en inblick i olika arbetsrollers perspektiv och uppgifter under en sådan process. Med hjälp av förundersökningens fynd togs skisser fram och en landningssida utvecklades bland annat genom programmeringsspråken HTML5, CSS3, LESS, JavaScript, .NET och C#.

En attraktiv kollektivtrafik : Enkla metoder för ett ökat resande

The purpose of this paper is to find out if there are any simple solutions to attract an increased use of public transportation in a smaller town in Sweden. Simple solutions are measures that can be taken within the current budget, and which do not require large investments and extensive political decisions. In order to search for possible solutions I needed to find out which factors and attitudes that determine why people choose public transportation and peoples? traveling habit. I have made a survey study of satisfaction and attitudes among the consumers of a public transportation company in Växjö; Länstrafken Kronoberg.

Undervisningsbehov vid ischemisk hjärtsjukdom - en litteraturstudie om patientens uppfattning

The aim of this study was to determine the self-perceived learning needs in patients with Coronary Heart Disease (CHD). CHD is the leading cause of death worldwide. Poor compliance is one of the causes of rehospitalisation. Patients suffering from CHD need education in order to manage their disease and prevent readmission to hospital. As hospital stays diminish the time available for patient education is limited.

"Det handlar om att hitta rätt bok till rätt person vid rätt tillfälle": En undersökning av läsfrämjande verksamhet för ungdomar i åldern 13-19 år.

The purpose of this Masters thesis is to investigate librarians views on reading and reading promotion for young people. The main issue is if activities in reading promotion for people between the ages of 13-19 years can result in inspiring non-readers to actually become readers. To find the answers, qualitative interviews were held with eight librarians. The literature review covers research on the reasoning of young people on reading, a historical review of fiction and reading, a review of arguments on the benefits of reading and finally a chapter which concerns reading promotion activities. The result of this study showed that the conceptions of reading promotion and book talk are very complex and that they each can have different meanings.

Tillämpning och utvärdering av kriterier för eTjänstetydlighet och handlingsbarhet : Actability, eTjänstetydlighet, MA/SIMM

A sequence of actions in the world have influenced the information science, one of these actions is the lateral movement in how companies use their IT-systems. IT-systems today, in comparison to before, are used by companies to improve their relationship with their customers. Every year a big amount of money is spent on developing and improving IT-systems. That is why it is important to develop and create IT-systems that are clear, and which encourage, enable and simplify a user?s action.

Vi-kan-ju-banken -Hälsorelaterat förändringsarbete i arbetslivet (Health promotion in the workplace)

With starting point in the increasing ill-health in Swedish working life today, in form of for example absence due to sickness and early retirement pension, and the knowledge that the working environment effects peoples health in a big extent, I found it very interesting to inquire into how people within the working life experience health promotion and how this can be developed. A qualitative method was used to receive a deeper understanding for the employees? experiences and data was collected through semi structured interviews with employees on a bank called Ikanobanken, in Älmhult. The result shows, among other things, that respondents find responsibility and the opportunity to influence the learning processes and development important. It also became clear that the respondents find participation, motivation, communication and safety essential factors when related to changes in health behaviours.

Ledarskap vid personalnedskärningar : ett ledarperspektiv

Kommunalt klimatarbete - exempel från Strängnäs och Sala

 The aim of this essay was to examine the way preschool teachers and children converse during school meals, and also the way preschool teachers start and develop conversations during meals. The conversations were analyzed from the topic of conversation and the teachers' ways of using language acts such as questions, remarks, exhortations. The study was based on observations, tape recording and contact schedule. The result shows that the topic of conversation is significant for how involved teachers are in conversations during meals. The result also shows how conversations develop or end depending on what language acts teachers use.

På jakt efter spår i språket : och reflektion i skolan

Our language bear traces of who we are and of the culture we live in. As human beings we create language in interaction with other people and with our society. Media and commercials are other factories that strongly influence our everyday life as well as our language. With this study we would like to illuminate how our surroundings influence our language. We focus on the language of young people and their use of symbols, phrases and expressions when they reflect on relations.

Kommunikation av kostråd : På unga vuxnas villkor

The purpose of this thesis is, through both a quantitative and qualitative study, to map out how the interaction appears between the established parties and the radical right-wing party, the Sweden Democrat?s (SD) and their core issue ? immigration in the Swedish parliament. By applying analytical dimensions on the parliamentary protocols regarding the immigration issue between the years of 2010-2012 this study will get an insight on how the argumentation concerning immigration has developed since their entrance into the Swedish parliament in 2010. The result shows that SD, through the rejection treatment of the established parties, fulfilled the three conditions which accordingly to the study's theoretical framework are crucial for the party's future success. In the established parties? reception of SD regarding immigration, SD is, to a large extent, left unchallenged as the established parties rather focus on integration instead of challenge SD in the immigration issue.
