Lättviktsskivor till möbelindustrin har varit ett omskrivet tema i olika branschtidningar den sista tiden.Detta examensarbete beskriver och undersöker en ny konstruktion av en lättviktsskiva i massivt trä.Lättviktsskivan är uppbyggd som en sandwichkonstruktion i tre skikt. Ytskikten består av 6 mm tjockalimfogar och kärnmaterialet av profilerade distanser. Materialet är furu och lättviktsskivan har endensitet på 320 kg/m3 vid 39 mm tjocklek. Utifrån kontakter med utvalda tillverkare och användare avskivmaterial, samt genom tester, har denna konstruktion granskas och förslag på förbättringar har tagitsfram. Den ursprungliga distansen som var sammansatt av två halvor med centrumhål har ersatts av enmassiv distans med en liknande profilering.

The study also studied gender differences in relation to motivation orientation, coping strategies and stressors. A survey was conducted with a quantitative design. The study included 118 participants (43 women and 75 men) aged 18 - 42.

High-performance equine athletes have an energy requirement that often reaches twice the maintenance requirement. Horses are grazers and adapted to a grass diet, and diets high in grains and concentrates are associated with digestive upsets and behavioural disorders. It could therefore be of interest if the energy requirement of a high-performing horse could be met by forage. It is important that the forage have a high concentration of energy so that the horse is able to consume the whole amount of energy needed from the forage without exceeding the maximum voluntary intake. The purpose of this literature study was to investigate if the energy demand of a high-performance horse can be covered by forage produced under Northern Swedish climate conditions.

Fetma och övervikt är ett allt mer vanligt problem över hela världen och därav ökar även överviktskirurgin. Gastric bypass är den vanligaste metoden i Sverige och ses som ett redskap för viktminskning. För att bibehålla viktminskningen spelar andra faktorer än operationen en roll hos patienterna. Studiens syfte var att finna framgångsfaktorer vid en bibehållen viktminskning postoperativt. Metoden var av fenomenologisk narrativ karaktär och datainsamlingen skedde med hjälp av intervjuer.

This Master thesis discusses the development of a virtual human soft tissue object for use in exercise applications of various medical procedures.The soft tissue object to be developed shall look like, feel like and behave as living human tissue. It shall give the user a realistic feeling of weight, softness and roughness, and shall behave in a correct way for exercise purposes. The soft tissue model is to be used in a three dimensional stereo graphic environment with haptic feedback. A prototype for practicing the procedure of inserting a catheter is built. The prototype is used to evaluate the potential of the virtual environment for medical exercise applications, and to assess the realism and usability of the soft tissue object.

Syftet med denna studie var att uttyda faktorer som bidrar till en långvarig beteendeförändring. Beteendeförändringar är i regel svåra att vidmakthålla och forskning har visat att ett flertal faktorer krävs för att nå ett långvarigt ihållande. Exempel på faktorer var känsla av sammanhang, kunskap, självkänsla, självtillit, reflektion, medvetenhet, motivation och gruppstöd. En fallstudie har genomförts på en viktminskningsgrupp för att se resultatet ett år efter deltagandet. Fem personer svarade på postenkäterna som skickades ut i uppföljningen.

The study explores different aspects of how a social organization is created and maintained in the space between the institution and the individual. Based on fieldwork, participant observation and individual interviews in the housing estate of Hageby, Norrköping, this ethnographic study examines how and why the organization ?Ditt Nya Hageby? was created, as well as the unanimity between the purpose of the organization and the engagement of the members. Two projects within the organization are especially examined, along with the roles of the two members behind them. The study presents three perspectives from which ?Ditt Nya Hageby? can be viewed.

The purpose of this Master?s thesis is to examine how the gender system is described in chick lit. The analysis is based upon seven chick lit novels. The primary theoretical point of departure is Yvonne Hirdman?s theory about the gender system, the hierarchical order and the separation of the sexes.

Denna systematiska litteraturstudie behandlar ämnet modersmål eller som det också kallas heritage language. Syftet är att med hjälp av diverse vetenskapliga artiklar komma fram till vilken roll språket spelar i en individs utveckling. Detta anses vara viktigt då man i lärarutbildningen ofta lyfter fram den enskilda individen i ett klassrum och det är då viktigt att skapa en förståelse för de ungdomar i dagens Sverige som har ett annat heritage langauge än just svenskan. Artiklarna visar att de ungdomar som fått lära sig sitt heritage language känner en koppling till sin kultur medan de som inte har fått möjlighet till det känner att de saknar något. Genom sådana resultat har man därför kunnat komma fram till att inte bara finns det en stark koppling mellan ens språk, kultur och identitet men att den också är mycket viktig..

The increased travelling of today makes nodes along travelling routes more and more important. This is very much the case of petrol stations. They constitute important nodes in the road network, filling up thirsty fuel tanks and hungry stomachs, guiding road users and providing vehicle-services. In this thesis the role of the petrol station for road users was investigated in order to find out if the petrol station was a potential hot spot. We performed an ethnographic field study at a petrol station and found that a great number of visitor activities took place at the petrol station.

I företag och organisationer har många verksamheter blivit beroende av informationsteknologi. Det krävs i många statliga myndigheter att datorsystemen fungerar för att de ska kunna genomföra sin dagliga verksamhet, det är systemförvaltningen som ser till att detta fungerar. Idag satsas resurser på att utveckla systemen utifrån tekniken och inte från användarnas perspektiv. Det innebär att systemen inte tillgodoser användarnas behov och önskemål vilket kan leda till ett motstånd till att använda systemen. Konsekvensen kan bli att nyttan med systemen inte uppfylls.

By comparing the experience off interaction in a life world with a drug habit and a life world without a drug habit you might find how they differ. We asked four former drug abusers in four semi structured interviews to describe their experiences off interaction under these two circumstances. The difference between the two life worlds when it comes to interaction is that in the drug abusing life world our informants describe that communicative action has to stand back for a more goal oriented action. In the drug free life world, communicative action on the other hand is experienced as the most important action. The difference is about wether interaction is goal oriented or oriented at understanding.

This thesis focuses on the construction of drystone walls in the county of Sm?land, as well as their historical value and significance to the county. In Riksantikvarie?mbetets Plattform Kulturhistorisk v?rdering och urval, a directory for historical evaluations of buildings and objects, the first clause is to describe the object and its history. When trying to do this, the lack of literature focusing on the constructional elements of drystone walls and their history became an issue and is what prompted the writing of this thesis. With a study of different handbooks, a compilation of the constructional elements of the walls were put together.

With the advent of powerful multimedia capable mobile phones, the market for mobile services is flourishing. Zenterio AB's Halfpipe Active Desktop is a complete distributed mobile service platform a with a powerful server and platform-independent client. The communication between the client and server takes place over a GPRS-capable mobile network. The purpose of this thesis is to develop a secure communications protocol for use between the Halfpipe Active Desktop client and server. This is done by determining requirements, analyzing candidate protocols and then by designing the final protocol.

SJ is a government-owned passenger train operator in Sweden. SJ currently uses asystem called Ford for control and monitoring of maintenance. Technical andorganizational factors have given Ford the character of a monolithic system withoutflexibility and conditions to meet SJ's increased requirements.The main purpose of this master's thesis is to investigate how data quality can bedefined at SJ and to examine the data quality in Ford. This will give SJ an indication ofwhat their quality efforts should focus on in the future.The technical data quality parameters found are: accuracy, timeliness, completenessand consistency. The user centred data quality parameters are: accessibility,understandability and reliability.
