Akrylmonomerer i kombination med polyuretandispersioner skapar polyuretanmodifierade akrylatdispersioner, PUMAs. En PUMA är en typ av vattenbundet bindemedel som används i färg och lack. För att utvärdera hur de olika akrylaterna påverkar en PUMA, testades akrylat monomerer genom att svällas in i polyuretandispersioner. Egenskaperna hos en PUMA visade sig vara beroende på typ och mängd av akrylat.Acrylic monomers in combination with polyurethane dispersions form polyurethane modified acrylic dispersions, PUMA’s. A PUMA is a type of water borne binder used in lacquers and paints. To evaluate the effects different acrylic components have on a PUMA, swelling of acrylic monomers into polyurethane water dispersion was made for different acrylics. It showed that the properties of the PUMA can be

This thesis studies the choice of floatation method using a dataset based on 703 public offerings in Sweden between 2006 and 2017. A logistic model is utilised to study the determinants of underwriting, an ordinary least square model to estimate the direct cost of floatation, and the cost of underwriting is estimated using the Heckman sample selection model. The results are generally aligned with

As the boundaries between different communication disciplines blur, PR experts are forced to operate in increasingly competitive business environments. They are pressured to prove the usefulness of their activities in measurable terms. Evaluation techniques are key to this challenge as they have the potential to win over organisational decision makers and to help steer communication programmes ef

As a respond to the development of Internet and Digital technologies, EU listed creation of Digital Single Market (hereinafter referred to as: “DSM”) as a strategic goal. The development of DSM would contribute in securing competitiveness within the Union. Establishment of DSM inevitably raises an issue of data management in the EU and in order to successfully form DSM, EU needs to create a harmon

Explaining how social regulations of inclusion among raid-oriented guilds in World of Warcraft are regulated by code was the approach chosen for this thesis, as an attempt to take on the perspective of consensus. By looking for consensus rather than conflict, it was possible to detect possible indicators for social exclusion in the code of the in- game environment. Data on social norms was collec

Around the world, the treatment of food waste is a major administrative and environmental problem throughout the food supply chain. Beijing, as any other mega city, is facing vast issues of sustainable food waste treatment in addition to efforts for food waste reduction. Presently the majority of Beijing's food waste is treated together with the mixed residual waste in landfills (53%) and inci

This study explores entrepreneurial decision-making with respect to non-analytic and analytic behaviour among novice and expert entrepreneurs. In order to understand and categorise subcomponents, or strategies, of these two styles of decision-making think-aloud protocols were used. By exploring and comparing behaviour within various entrepreneurial scenarios, and segmenting it using precise catego

It is widely accepted that nancial mark behaviour is characterized by periodicity. However, in academia and practice financial markets are often modeled as time consistent, resulting in static investment strategies that are assumed to be ecient. This has great implications on investors' allocation decisions and in valuation of risks and performances. In this thesis we consider different risk f

Jonathan Swift’s Gulliver’s Travels and Terry Pratchett’s Discworld novels set in Ankh-Morpork are similar enough that both can be treated as belonging to the subgenre of comic fantasy. The narratives foreground the fantastic, written to entertain and amuse its readers but also contain societal criticism in the form of satire or parody. This paper compares the unnatural aspects of Gulliver’s Trave

This paper studies whether Swedish workers use the unemployment insurance (UI) system as a pathway to retirement. We use longitudinal register data consisting of weekly UI benefit payments for the period 1999 to 2015. In Sweden, individuals are eligible for UI benefits for a maximum of 427 days. This creates an artificial benefit threshold at 427 days prior to the official retirement age. We use a

Information and communication technologies (ICTs) become more advanced and more accessible which leads to new ways of work. A rather new phenomenon is that of location independent workers (LIWs), who are enabled by these technologies to work while traveling the world. New ways of working assumingly lead to changes in the work-nonwork interface. This study takes a demands and resources approach to

Arbetet utforskar möjligheterna att lyfta fram och synliggöra byggnader som kan ha ett publikt intresse och tillgängliggöra områden och delar av våra städer som idag bara är nåbart av en liten del av befolkningen. Genom att öppna upp mer av vår omvärld ökas förståelsen för hur vårt samhälle fungerar samt bidrar till en starkare samlevnad. Arbetet använder sig av vattenkraftverk som exempelbyggnad

This study examined the acculturation strategies of immigrant adolescents in Sweden and their relation to the mental health symptoms. The participants were 101 immigrant adolescents and 52 Swedish adolescents 15 to 19 years old. ‘Immigration paradox’ was examined comparing the mental health of first and second generation of immigrants and the native Swedes. Youth Self Report was used to assess men

Viktor Orbán as the Prime Minister of Hungary is a figure that dominates headlines both at home and abroad. During his time in Hungarian and European politics, he has never shied away from using history to bolster his political message. Following the ongoing refugee crisis of 2015, he has employed history as tool against refugees. This paper aims to investigate which aspects of Hungarian history O

Research Problem:​ While research on rapid venture growth has mostly focused on high-growth firms in later stages of development, the topic has become increasingly important to understand for new ventures as well. With the establishment of crowdfunding as an alternative source of financing, companies have access to tools that enable quick expansion of their marketing, funding and distribution capa

Background: The IKEA Range & Supply organisation consists of business areas (BAs) and categories. BAs work with product development toward end-customers while the material-based categories work toward suppliers with purchasing and sourcing related tasks. There exists an internal cross-organisational interface between these units and IKEA recently created Sourcing Assignment as a tool to encour

Networking has been found to be ever more important in the economy of today’s globalised world. In recent years, public relations has started to pay attention to the process of networking and network theories. A branch which is understood to be based on networks and which is at the centre of current economic processes is that of creative industries. Creative industries consist of a diversity of sm

The blood-brain barrier (BBB) is a highly selective barrier separating the brain from the circulatory system. The physical barrier is built up by a monolayer of endothelial cells, which is the main component used for in vitro modeling. To create more physiologically relevant in vitro models, the field of organs-on-chips has recently been introduced, combining microfluidics and microengineering to

Den här studiens primära syfte är att jämföra och utvärdera två medborgardialogs metoder. De två metoderna är samrådsmöten och Public participatiory GIS (PPGIS). Samrådsmöten är en etablerad metod inom medborgardialog för samhällsplanering i Sverige. Uppsatser syftar till att pröva hypotesen om PPGIS är en effektivare metods för medborgardialog. Uppsatsen utvärderade först de två metoderna med hThe primary purpose of this study is to compare and evaluate two public participation methods. The two methods are public meetings and Public participatory GIS (PPGIS). Public meetings are an established public participation method for urban planning in Sweden. The thesis aims to test the hypothesis if PPGIS is more effective as a public participation method. The thesis first evaluated the two me

Beer is one of the most favorable alcoholic beverages and has a large consumption in the world. However, there are fewer beer consumers who perceive the lacing character after drinking. Four different concentrations (25 mg/L, 50 mg/L, 75 mg/L and 100 mg/L) of iso-α-acid and two levels (0.3% and 0.15%, w/w) of protein content were investigated towards lacing property on modified hydrophilic and hyd
