This degree project has been carried out in cooperation with Enertech AB in Ljungby and is pilot study to automating all current manual soldering. The soldering process accounts for a large part of the processing cost in the production of a heat pump. The process is also a quality risk and has a major impact on the lifetime of the final product.The Main task of this project has been to evaluate automation of the soldering process, to develop automation solutions and a principle layout, to draw the design changes required for the automation and to calculate the supposed solution.This pilot study has resulted in a suggested automation solution using laser as a heat source for soldering. Calculations of the solution show that a automating a laser soldering cell is very profitable..

The purpose of this study was to examine how modern information and communication technology influence collective action within the framework of social movements. By studying the protests in the Arab World 2011, and focusing on the social movements in Suleimanya in northern Iraq, by observation taken on place, the essay discusses that collective action is closely related to the use of technology, for example cell phones and Internet.Result shows that modern communication technology has enabled immeasurable access andconnection between individuals throughout the world, which seems to be different from previouscollective action. The new communication channels in the form of social media, has been used for the dissemination of information and news, documentation, organization and membership recruitment in the social movements in the Arab World and Suleimanya. The new social movements have the tendency to be decentralized and flattened organized, they are now self-organizing and that they only do a whole as global patterns, as evidenced by the social movements in the Arab World andSuleimanya..

This degree project is an investigation of solar cells and their ability to deliver electric power as well as reducing the need for cooling. The main object of interest is a BASE-X shelter. The shelter is purchased by the Swedish Defence Materiel Administration, FMV to be used for command and camp in the new force called Nordic Battlegroup, NBG. The demand on the equipment is firstly that it should have a small weight to be easy to transport and handle and secondly to be easy to bring up fast. Therefore the choice of solar cell technology fell on thin film cells.

Numera satsar allt fler systemutvecklingsorganisationer på virtuella utvecklingsteam för att därmed öka effektiviteten och konkurrensfördelarna i informationssystemut-vecklingen. Tillämpning av virtuella utvecklingsmetoder skapar stora utmaningar både när det gäller teknik och kommunikation. Virtuell samverkan ställer krav på en helt ny typ av utveckling och implementering då IT-baserade interorganisatoriska informationssystem som knyter samman olika deltagande parter och som ska stödja kommunikation och affärsprocesser i nyskapade virtuella organisationer ska designas. Denna rapport undersöker eventuella skillnader mellan designen av traditionella in-formationssystem och designen av ett webbaserat interorganisatoriskt informationssy-stem för virtuella informationssystemutvecklingsorganisationer. Undersökningen genomförs i form av litteraturstudier då såväl svenska som utländska vetenskapliga publikationer granskas och analyseras.

Since several lifestyle diseases are associated with obesity much research is carried out within the area. Researchers have found that oxidation of fatty acids within the body?s cells may give rise to peripheral signals which regulate food intake, but it is still unclear where such a mechanism takes place. Although much evidence suggests that it is the hepatocytes in the liver that send signals regulating food intake, some researchers have begun to question this theory. Instead they argue that the mechanism takes place within the enterocytes since they are well localised in the gut for such assignment.

This project is a literature study with the hypothesis that Arctic climate has a positive effect on the accumulation of metabolites in berries. Plant metabolites are often divided into primary and secondary metabolites. Primary metabolites such as proteins and nucleic acids are essential for cell function, while secondary metabolites are often non-essential, but have important functions regarding reproduction and survival. The berries mentioned in this project are from the families Ericaceae, Rosaceae, Elaeagnaceae och Grossulariaceae.The conclusion drawn from this literature study is that it is not obvious what favours accumulation of metabolites in berries. Other factors aside from climate affect the production of secondary metabolites, such as time of harvest, cultivars and ripeness.

Bakgrund: Transplantationskirurgin är ett relativt nytt område som hade sin framväxt i Sverige på 60-talet. Transplantationsprocessen är en krävande process som har en stor påverkan på patienternas livssituation. Det finns evidens för att anhöriga till svårt sjuka är en grupp som riskerar att drabbas av ohälsa på grund av den påfrestande rollen som vårdare. När en svår sjukdom drabbar en person stannar familjens liv upp och de anhörigas behov blir åsidosatta. I transplantationsvården är anhöriga ett viktigt stöd för patienten och därför kan det antas att de anhöriga går igenom en påfrestande process och är själva i behov av stöd från vården.Syfte: Att öka kunskapen om personers upplevelser av att vara anhöriga till patienter som ska eller har genomgått en transplantation för att öka sjuksköterskors möjlighet att kunna ge stöd.Metod: Arbetet är ett resultat av en litteraturgranskning där flera sökningar på databaserna Cinahl, PubMed och Scopus gjordes och artiklar valdes ut för granskning.

Bakgrund: Under 2008 genomfördes 29 hjärttransplantationer i Sverige. Idag finns det möjlighet att genomföra blodgruppsinkompatibla transplantationer. Livet efter en hjärttransplantation medför fysiska restriktioner och ett livslångt beroende av medicinering och återkommande läkarbesök. Syfte: Syftet är att belysa personers livsvärld det första året efter en hjärttransplantation. Metod: En litteraturstudie baserad på tio artiklar.

Fertility is of central interest in the dairy production but has during the last decades declined. Increased milk yield has resulted in high pressure on the metabolism of the dairy cows that are supposed to manage the transition from dry cows to lactating cows within a few weeks around the parturition. Much indicate that metabolism and fertility are closely linked, with insulin playing a substantial part. There are many studies suggesting that the main part of gestation loss can be found during the early embryo development, a period which can be studied in vitro. The aim of this study was to test the effect of insulin during maturation in vitro and to evaluate two different fluorescent stainings on oocytes and embryos; a nuclear stain and a staining of apoptotic cells through the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-method. Bovine cumulus-oocyte-complexes (n=991) were aspirated from abattoir-derived ovaries.

This paper examines how pupils with a non-Swedish background, in a secondary school in Stockholm?s suburban, Sweden, interpret and absorb the contents of school-room classes. It also examines whether the interpretations are influenced by a power-relation between teacher and pupils. The pupil?s interpretations, including their values and perceptions as regards to the content, are central to our study.Firstly, classes on world conflicts and corporal punishment for children were observed and these observations were the foundation to this study.

This report is the concluding part of the course national minorities, main focus on design, at Luleå University of Technology spring 2007. The purpose of this written examination is to produce a prototype to a product, which can be used both when marketing Kiruna as a student municipality and when recruiting students to the study programmes Kiruna offers. The product has been produced through systematic problem solving, where methods to fix the problem, gather facts, examine and come to a solution have been used. The product should in one way or another get the student to think of Kiruna as a student municipality and it should also appeal to the target group ? the students.

The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners. To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.

Subklinisk mastit (juverinflammation utan synliga symtom) är vanligt hos flera mjölkproducerande arter inklusive får. I kött- och pälsfårbesättningar kan subklinisk mastit ge lägre slaktvikt hos lammen till följd av minskad mjölkproduktion hos tackan. Risken att lammen försöker dia en annan tacka ökar om de inte blir mätta av sin mammas mjölk. Eftersom de flesta mastiter är bakteriellt orsakade kan lammens tjuvdiande vara en potentiell smittväg för juverinfektioner. För att förhindra smittspridning behövs snabba och pålitliga fältmetoder för att detektera juverinfektion. Syftet med studien var att kartlägga förekomsten av juverinfektioner hos tackor med kliniskt friska juver i svenska kött- och pälsfårbesättningar.

Syftet med denna studie var att undersöka hur personer med egenadministrerad peritonealdialys (PD) upplever sitt dagliga liv. Metoden var en intervjustudie där sju personer som behandlades med PD intervjuades med hjälp av en semistrukturerad intervjuguide. Materialet som analyserades med en manifest kvalitativ innehållsanalys resulterade i tre huvudkategorier: kroppsliga förändringar, upplevelser av PD-behandling samt egenvård. Resultatet visade att PD hade inverkan på olika plan i informanternas dagliga liv. Ett viktigt fynd var hur informanterna uppfattade att PD hade lett till vissa kroppsliga förändringar, exempelvis vad gäller vikt och aptit.
