I Sverige tillverkas betong normalt med glaciofluviala grusavlagringar(naturgrus). På senare år har tillgång på naturgrus blivit starkt begränsade i vissa regioner och man vill av miljöskäl minska förbrukningen av det som återstår. Återvinnig av material som kan ersätta detta är både bra av miljöaspekt samt öppnar väg för produktion av betong med nya egenskaper.Med lättballastbetong avses betong i vilken ballastmaterialet helt eller delvis består av någon typ av lättballast som har en partikeldensitet som är markant mindre än vad som är normalt för normala bergartsmaterial såsom granit, gnejs eller kalksten. Lättballast är porös, dvs innehåller hålrum, och får därför lägre hållfasthet än normalballast. I lättballastbetong bestämmer lättballastpartiklarna många av betongens egenskaper, såsom hållfasthet, elasticitetsmodul och krympning.Examensarbetets inledande del är en state-of-the-art rapport som omfattar tillverkning av lättballastbetong i allmänhet, både i färsk och hårdnade tillstånd, samt dess beståndsdelar med fokus på skumglas som lättballast.

The purpose of this master thesis is to study the correlation and meaning of current ideas and practice at the public library of Gothenburg. This was done by comparing the visions and ideas expressed by the library through the library plan, with how the daily practice looks. For the theoretical framework organizational theory is used and research data was collected both from public documents and through observations. The public library of Gothenburg were chosen for the study because of it's newly renovated facilities. The idea is that these facilities make a suitable study object of the current ideas and priorities of the public Swedish library in general.The results show that the public library practice in Sweden still rests on the original public library ideas such as offering information for free and treating every user as equal.

Abstract The main purpose off this essay is to understand what different ways women and men use to communicate and make themselves acknowledged by their co-workers.  This is done by interviews with people at an ordinary office and trough observations at the workplace. A qualitative method was entrenched and seven respondents, four women and three men, age 43-55 was interviewed. The theoretical frame contains theories from Goffman?s dramaturgic perspective such as roles, facade etc.  The theories concerning gender come from Hirdman?s different analyses on how the relations between men and women take form. The data collected shows that men and women use their body language, voice and accessories in different ways to make themselves acknowledge at the office.

The Go Down Arts Centre is a proposal for a new building to an existing organisation in Nairobi, Kenya. The proposal relates to the scale of the city by making a statement on a future urban path, and by welcoming the city in to the building. The proposal houses both activities affiliated to Go Down, such as studios and rehersal rooms, as well as opportunities for the visitor to meet and interact with the culture produced at Go Down, both in formal and informal settings. The building is closed to its surroundings, apart from a grand entrance towards the urban path. There, the city passes through the building to an inner courtyard, where the communication to all the rooms and activities takes place.

Abstract Title: Veckorevyn.com. A study from power relations in the world of blogs Author: Klara Sigfridsson Department for Media and Cultural Studies, Malmö Högskola Tutor: Kristoffer Gansing This is a report that aims to research upon Fairclough´s Critical discourse analysis to emphasise the power relationship between professional bloggers and former amateur bloggers at the fashion-entertainment web page Veckorevyn.com. Professional bloggers as they appear in the research object and their power within the Media seem to be a subject that is very relevant these days. This paper will look at different factors that make professional bloggers popular and as an example on their responsibility as a role model. However, amateur bloggers do have an importance in this discussion as they are more and more competing with the professionals.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

The subject of this paper is the library job market in Sweden 1975-1995. Job advertisementsin the periodical of DIK Association (the Swedish federation for occupational groups thatworks with documentation, information and culture) have been studied.1975, 1980, 1985, 1990 and 1995 there were 2 170 advertisements of situations for librarians.They have been examined with focus on the following:situation description:qualifications requested:? type of library? size of municipality?county? hours per week? duration? designation? tasks? education? knowledge of languages? knowledge of specific subjects? knowledge of computers? experience? driving licence, carStatistics have been made. The figures of the five years have been compared to give a pictureof the development.The results have also been compared with what has been written about the changes that arehappening on the labour market in general, and similarities and differences have been pointedat..

Earlier research has shown the difficulty of defining insulting behaviour in the workplace. It has been noted that the individual and subjective definition is connected to the specific situation in which the potentially insulting incidence occurred. In this study we designed a quantitative questionnaire in order to hopefully elucidate the comprehension of insulting behaviour and furthermore enable a more in-depth investigation on how important the contextual meaning is. This study examined 140 (n=140) working adult?s attitudes towards insulting behaviour in the workplace and the importance of the contextual variables.

Globalization is described as processes of economic, social and political character and a tendency in the field has been to study these aspects of the phenomenon separately. Another common feature of previous studies is to relate to the field at a high abstraction level and talk about the effects and changes in general terms. Such studies of quantitative and statistical nature in which people are constituted as homogeneous groups hides the fact that the relationship between social attributes and context creates unique positions where the effects of globalization are diverse (Sprague, 2005, pp. 16 - 18). The purpose of this bachelor thesis is therefore to break with this entrance to the field and instead focus on a micro level perspective.By conducting a qualitative interview study guided by the globalization theory of the Globalife research team, which shows how structures at the macro level can be understood to affect the micro level, the aim is to reveal potential knowledge gaps within the field.

The token economy program, which is a method for behaviour modification, has been used worldwide for different groups within different settings in order to vhange behaviour.Research has found the token economy program to be effective. However, research is limited to quantitative and experimental studies, and Swedish research in this field is brief. Nevertheless, the program is used in several institutions n Sweden. A qualitative study in Swedish settings could therefore be useful. The purpose of this paper is to examine the experiences of a token economy program using qualitative interviews.

This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews.

Syftet med den här essän är att undersöka om det går att synliggöra ett mellanrum som upplevs finnas mellan tillsynsansvarigs upplevelse av förskolans kvalitet, hur förskolan beskriver sin kvalitet och vad kvalitet är för barnen i deras vardag på förskolan.Mellanrummet gestaltar sig som ett fält med information som är svår att få syn på. Essän utgår ifrån två berättelser om hur barn kan uppleva sin vardag på förskolan och vad kvalitet kan vara utifrån ett barnperspektiv.Berättelserna har också fokus på mötet mellan tillsynsansvarig, förskolechefer och pedagoger. Deras roller prövas utifrån att vara nyckelpersoner som har att föra in begreppet kvalitet i förskolan.Teorier och styrdokument om vad kvalitet är i förskolan ställs i relation till tillsynsansvarigs, förskolechefers och pedagogers roll. Aristoteles kunskapsbegrepp fronesis blir ett stöd för att få syn på den praktiska kunskap som nyckelpersonerna äger och utövar.Tillsynsbesöket granskas i skrivandet som ett kontrollerande möte men också som ett möte med möjlighet till utveckling. I mötet har tillsynsansvarig två roller som lyfts fram, den kontrollerande och den vägledande.

The thesis objective was to study the partnership between the municipality of Gothenburg and three nonprofit organizations concerning the mobile EU-citizens. The study examines how the EU-enlargement affected Sweden and eventually the municipality of Gothenburg, and how Gothenburg responded to the new situation regarding the target group. The thesis contains one case study and the empirical data are based on semi structured interviews with politicians and officials from both the public- and the nonprofit sector. The results were screened with New Institutional Theory, Resource Dependence Theory and Decision Making Theory: Rule Following. The theories were used to locate any type of isomorphism, resource dependence and rule following in the partnership.

This thesis is basically an attempt to discuss the intrinsic intersubjective nature of the so-called ideal sciences, i.e. geometry or arithmetic. Based upon a thorough analysis of Husserls The Origin of Geometry and Derridas Edmund Husserl's Origin of Geometry: an Introduction this thesis takes geometry as an example of an ideal science. The main question of the thesis is how an ideal science or object is constituted. The thesis consist of two main chapters - ?Geometry and Historicity? and ?Language?- and a concluding discussion.

Syftet med denna rapport är att utreda vad matematik- respektive karaktärsämneslärare på yrkesprogrammen på gymnasiet anser att det finns för för- respektive nackdelar med en ämnesintegrering mellan deras ämnen. Med hjälp av en enkät har de två grupperna fått delge sina för- och nackdelar samt i vilken utsträckning de tillämpar en sådan ämnesintegrering. Enkäten användes också som underlag för en intervju som låg till grund för en beskrivning av hur ett ämnesintegrerat arbete kan gå till. Majoriteten av lärarna var positiva till att ämnesintegrera och ansåg att de tillämpade en sådan undervisning men endast ett fåtal samarbetade med sina kollegor över ämnesgränserna..
