Problemställning: Cementproduktionen i världen står idag för 5% av världens totala utsläpp av koldioxid. Höjda miljökrav de senaste decennierna har gjort detta till en belastning för cement och betongindustrin. Situationen har hanterats främst genom att ta fram nya cement där den hållfasthetsskapande Portlandklinkern delvis ersatts med andra material som genererar mindre koldioxidutsläpp. Ett anna
The society is constantly changing because of the globalization and the requirements of specialization increases. In regional growth policies regional expansion is advocated as a mean of increasing economic growth. Increased mobility is a prerequisite for regional expansion, something that conflicts with established climate and transport policy objectives. This essay examines how municipalities in
This report presents how far NCC current VDC tools and methods in building construction can be implemented in road and infrastructure projects also what new tools, methods that can be created helped by pre-selected software’s. VDC is well developed within the construction of building and research and resources in the field have been spent under a longer period of time unlike in road and infrastruc
The goal of this work was to create a model for characterizing bird species through recordings of their song. A large set of twenty species with 10+ recordings in each species was considered and the algorithm used time-frequency models for the characterization. Three different approaches were used in an attempt to build the foundations for the final model in a bottom to top manner. The resulting m
LIDAR-data från mätstationen Polly, som är en del av Arrhenius-laboratoriet och belägen på Stockholms universitets tak, används för att bestämning av planetära gränsskiktshöjden. För detta ändamål användes en stabil ”wavelet covariance transform” metod för analys av LIDAR-datasignalerna från åren 2011-2012. Endast molnfria dagar med högtrycks- förhållande är med i undersökningen för att minska mänLIDAR data from the Polly system on the roof of the Arrhenius laboratory at Stockholm University are used to determine the planetary boundary layers (PBL) height distribution. To this end, a wavelet covariance transform method is employed to analyze LIDAR measured data signals from the years 2011-2012. Only data with high pressure cloud free condition are used to reduce “bad” data. The main result
Abortion is an important aspect of the fertility decision and the impact of economic conditions on the wellbeing of individuals and families. This study investigates the relationship between business cycle indicators in the context of women’s growing importance in Sweden’s labor market and economy. It finds that female relative wages have had the strongest impact on increasing abortion demand. The
Mesozoikum anses ha utgjort en ”växthusperiod” i Jordens historia med avsevärt höga koldiox-idhalter i atmosfären samt förhöjda temperaturer, men det återstår många frågor att besvara angående klimatut-vecklingen för hela detta intervall. Tidig jura karaktäriseras till exempel av ett varmt klimat, och föregås och efter-följs av två kortare perioder med väldigt höga CO2 halter, som sammanfaller medThe Mesozoic was a so-called “hothouse” time period in Earth’s history, with high concentrations of atmospheric CO2 and elevated temperatures, but the exact climate evolution is not fully known for the entire inter-val. The Early Jurassic for instance is believed to have been a warm period, flanked by two episodes of extremely high CO2, coinciding with environmental degradation and mass extinction
This thesis applies a methodology based on the Novy (2013) ratio of trade barriers to identify variations in barriers to cross-provincial trade in the People’s Republic of China, econometrically tests for determinants of such variations, and together with the results of a field study determines the state of the current trade environment. Results of this study show the presence of such barriers to
Polymer based nanometer to micrometer size fibers and tubes are the bases for a wide range of industrial and medical applications and various research branches. They are capable of guiding light, carrying electricity and liquid or exchanging heat. Two production systems were established and built. These systems enable us to produce a wide range of tiny tubes & fibers. Light, nano-micro tubes &
Arbetet med medarbetares arbetsglädje speglas i den framtagna modellen kring arbetsglädje där förutom den psykiska arbetsmiljön fokus även råder kring en motiverande miljö, delaktiga ledare samt kommunikation och feedback. Medarbetare på Gekås Ullared anser att arbetsglädje är samt uppstår i gemenskapen med kollegor, den dagliga kontakten med kunder och beroende på ledarnas delaktighet i det dagli
Popular science summary Identifying an African Paradise Flycatcher using molecular techniques Five species of Paradise Flycatchers (Terpsiphone) occur in mainland Africa. Colour polymorphism and hybridization in these birds make species identification and defining species boundaries challenging. A melanistic individual was captured in Gashaka-Gumti National Park in Nigeria, and could not be iden
The purpose of this paper is to determine to what degree there are textual and conceptual similarities between the British National Party’s (BNP) and UK Independence Party’s (UKIP) construction of in-groups and out-groups. The focus is on the two discursive strategies nomination (attribution of word form) and predication (attribution of quality). For the present study I adopt the Discourse-Histori
This study examines work culture among the contemporary Swedish professional communication field. Key standards of the field and their origins are analysed through participant observation in branch seminars and interviews with practising professionals. The results indicate that status in the work culture is centred around innovative thinking, change and focus on the future – ideals related to Enli
Creativity has been of research interest for centuries and its relationship with other constructs has been established; however, these links mostly study creativity with a single other construct. The purpose of this study was to investigate the relationship between psychological safety, tolerance of ambiguity, playfulness and creativity; they have been individually linked together but no complex m
Problem: The case study company, BorgWarner, currently has no quantitative method for evaluating the risks connected to different inventory levels throughout their internal supply chain. Meanwhile there are internal goals for lowering the amount of capital tied in inventory. Purpose: The purpose of this thesis is to investigate how changes in the component and finished goods inventory levels affec
This is a report that covers the process and result of designing a two wheeled cargo bicycle in co-operation with the American bicycle manufacturer Specialized Bicycle Components. With cargo bicycles gaining more popularity I wanted to address common issues current users had with them. Through qualitative research in the Malmö & Copenhagen area, I identified issues with flexibility and size. T
This project started with a wide research of the life-cycle of clothes. The industry is problematic and unsustainable. To find a way to tackle the problem the life-cycle was divided into categories and brainstorming was done within these. The chosen category was the using of bought clothes. The aim was to prolong the life-cycle of the garments and engage the consumer in care and quality. The resul
The debate about the link between economic growth and foreign trade is still open amongst scholars. There exist four main hypotheses regarding the relation between imports, exports and economic growth. The first one states that growth can come only through increasing the volume of exports of the country, i.e. export – led – growth hypothesis. The second one (growth – led – exports hypothesis)
The purpose of this thesis is to study the marketing of Roskilde Festival through social media and Roskilde Road Trip Malmö as a case. My main research questions are: What does the maketing of the festival look like in social media? How does the marketing of Roskilde Festival relate to three of the four P:s? Is there something special about their marketing? Has the poster and the artists on it cha
