The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods. In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

The purpose of the study is to investigate the communication between exchange students and their host student trough Facebook. The study shows the importance of social cues and self-disclosure to maintain a relationship. The students? everyday use of Facebook helps them to remain connected to their social life locally and create new friendships. Cultural differences were shown in the way the students formed their expressions trough their messages to each other.

BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.

Studie syftar på att få kunskap om de faktorer som är av betydelse för gymnasieelever i ett utbytessammanhang..

Vi lever i ett stressigt samhälle där allt skall fungera och tiden är emot oss för det mesta. Ifall det gick att schemalägga alla händelser som skall och borde göras i ett gemensamt kalendersystem så skulle det förenkla situationen för många personer, som skall träffas eller andra händelser som kan uppstå. I detta arbete undersöks det ifall en ny öppen standard för kalenderöverföringar skulle fungera, samt om den är tillräckligt bra för att användas, eller om den skall undvikas. Inom arbetet implementeras en prototyp som baseras på denna kalenderöverföringsstandard. Den prototyp som framtogs, tillhandahåller de grundläggande funktionerna i CAP, jämförs med Microsoft Exchange.

Idag föreligger ett stort intresse för att placera i etiska fonder, men det råder delade meningar om vad en etisk fond innebär. Det finns ingen universell applicerbar kod utan det är upp till fondbolagen själva att definiera vad som är etiskt för dem. Det är således svårt att fastställa något entydigt begrepp för vad som kan anses vara etiskt eller inte då begreppet etik är såväl subjektivt och relativt samt varierar över tiden. Allt oftare uppdagas hur företag världen över kopplas till svåra missförhållanden eller är inblandade i oetiska verksamheter. Flera av dessa företag ägs indirekt av oss konsumenter genom våra pensionsmedel och privat sparande i fonder.

This paper studies the research foundations created in 1994 from the former wage earners? funds out of a portfolio management point of view. Firstly it describes the seven largest foundations and their different portfolio management structures. Secondly it analyses the performance of these foundations measured as the intercept, Jensen?s a, in a linear regression of the excess returns of a portfolio versus a proxy for the market, as well as the Sharpe-ratio.

Detta examensarbete hade som syfte att undersöka hur förmedlingen av förväntningar ser ut i en nära relation. Frågeställningarna handlade om huruvida olika kommunikationsstilar hade någon påverkan och om det fanns skillnader mellan män och kvinnor, eller beroende på hur länge paren hade varit tillsammans, när det gällde förmedlingen av förväntningar i en relation. Social Exchange Theory (Thibaut & Kelley, 1959) har använts som grund för undersökningen eftersom den ger en tydlig förklaringsmodell över förväntningars inverkan på en relations tillfredställelsegrad. Metoden som användes var av kvantitativ art där enkäter var det instrument som tillämpades. Enkäterna fylldes i av 13 par som hade varit tillsammans i minst 6 månader.

In this study we have explored and investigated how journalist experience the relationship with politicians/press secretaries in the making of political news. The study examines how journalists see the balance of power between them and their political sources in the setting of the news agenda. To do this we have used a qualitative interview analysis. Our theoretical starting points have been based on the social exchange model. The social exchange model has a social psychological and sociological perspective that explains the interaction, social exchange and stability as a process of negotiation exchanges between parties and operators.

The purpose of the essay was to examine the role of the professional communicator in the Swedish Unemployment Funds. Focus was on measures carried out by the communicator to enhance and streamline communication and how the communicator supports their coworkers in their own communication role. In order to fulfill the purpose, two main questions were asked;? How do the communicators support and develop their coworkers communication role?? What to the communicators identify as challenges in their work in doing this?The theoretical base of the essay was Heide and Simonssons (2011) challenges for the professional communicator. The theory states that organizations communication processes are the foundation to its existence and development and that the professional communicator therefore needs a solid base with the possibility to monitor the whole organization.A questionnaire was sent to communicators in all Swedish Unemployment Funds and even though the non-response was rather considerable, the answers received was assessed sufficient to make an analysis.

Syftet med denna studie var att undersöka vilka metoder lärare använder vid undervisning för hållbar utveckling i grundskolans tidigare år. För att operationalisera begreppet hållbar utveckling i vår studie använde vi oss av fyra av de förmågor som presenteras i Inger Björneloos studie; förmågan att se helheter och sammanhang, förmågan att med inlevelse ha förståelse för andra människors livssituation, förmågan att se sin delaktighet och sitt ansvar samt förmågan att argumentera för olika ståndpunkter. Vi undersökte i vilken utsträckning relationen mellan lärares metodval och ett specifikt undervisningsinnehåll överensstämmer med de miljöundervisningstraditioner som växt fram i den svenska skolan. Studien bygger på en enkät som delades ut till lärare i en liten kommun i Sverige. För att analysera våra data använde vi oss till viss del av programmet IBM SPSS Statistics 22.Resultatet visade att det inte var några markanta skillnader gällande lärares metodval vid undervisning för hållbar utveckling.
