Bland de mest kraftfulla händelser som människor har observerat är gammablixtar. Blixtarna är korta utbrott av gammastråalning som ibland dyker upp i rymden. Forskare har länge misstänkt att kollisioner mellan neutronstjärnor ligger bakom en kategori av blixtar, de korta gammablixtarna. För några år sedan bekräftades forskarnas misstankar. De kunde då, med det nya LIGO-observatoriet, observera graShort gamma-ray bursts are often observed at large spatial offsets from their host galaxies. Neutron star mergers in double neutron star binaries have also recently been confirmed as a progenitor of short gamma-ray bursts (Abbott et al. 2017). We attempt to constrain uncertainties in the evolution of burst-producing neutron star binaries by generating a distribution of burst offsets from the neutr

Polylaktid (PLA)- en plast som har dålig nedbrytningsförmåga och borde kallas något annat Plasten polylaktid, PLA, marknadsförs som bionedbrytbart, någonting som faktiskt inte verkar stämma enligt olika studier. Plasten bryts inte alls ner under samtliga förhållanden i naturen utan kräver speciella anläggningar för fullständig nedbrytning. Inte heller tycks PLA uppfylla den europeiska standarden fThis paper aims to look at the positive and negative aspects of the biodegradable material poly(lactic) acid (PLA) compared to controversial plastics. This is done through a literature study. PLA is a biobased and biodegradable plastic that are used in for example medicine and packaging materials around the world. The results from this study show that the biodegradation of the material is not that

Our interest to conduct this study emerged from the intense debate, which took place prior to the law reform regarding sexual crime. The aim is to review selected parts of the new legislation from a functionalistic perspective to tell if the legal norm fulfills its purpose. This was possible with the help from a selected group of expert witnesses and their comprehension of the modifications that s

Denna studie syftar till att ta reda på hur nyexaminerade musiklärare ser på sin identitet som musiklärare och huruvida de också identifierar sig som musiker. Genom en kvalitativ intervjustudie har tre informanter svarat på frågor kring valet att bli musiklärare, musiklärarutbildningen och deras tidiga yrkessocialisation. Vägen mot ett yrkesliv som musiklärare förefaller inte för informanterna som

En våtmarks kapacitet – går det att optimera en våtmark för att minska såväl eutrofiering som brunifiering? Att använda en våtmark i syfte att minska såväl övergödning som brun missfärgning av vattendrag, är absolut möjligt, men hur och varför är frågor som behöver studeras mer grundligt. Däremot verkar placeringen i landet i kombination med våtmarkens procentuella storlek i förhållande till avrDue to changes in land use, as well as impacts from the climate change, our inland waters are now exposed to problems such as eutrophication and brownification. This complicates management to develop clean drinking water, as well as it leads to anoxic bottoms and reduces primary production. This literature review aims to see if wetlands can work as a natural filter to reduce both nutrients (nitrog

Att skriva musik är något som har varit närvarande under hela mitt liv. Jag skrev min första låt när jag var åtta år och efter det har musikskapande varit en stor del av mitt musicerande. Att jobba med barn i de lägre åldrarna har också varit ett arbete som lockat mig. Jag har dock känt att jag saknar kunskap om hur barn i den åldern tar till sig musik och funderat över om sättet vi musicerar med

I Aktiebolagslagen finns bestämmelser om tvångslikvidation på grund av kapitalbrist i 25 kap. 13–17 §§ ABL där syftet med bestämmelserna är att sätta upp en gräns för hur långt en förlustbringande verksamhet får fortsättas innan verksamheten måste avbrytas genom likvidation. Kritisk kapitalbrist innebär att bolagets eget kapital understiger hälften av det registrerade aktiekapitalet. Regleringen iThe Swedish Companies Act contains provisions on compulsory liquidation due to capital shortage in Chapter 25, sections 13–17 § ABL where the purpose of the regulations is to set a limit on how far a loss-making activity may be continued before the business must be interrupted by liquidation. Critical capital shortage means that the company's equity is less than half of the registered share ca

Den snabba utvecklingen av nya digitala verktyg leder till nya möjligheter för fjärrvärmebranschen inom områden som laststyrning och feldetektering. För dessa ändamål behövs tillförlitliga modeller som beskriver centralerna. Syftet med denna studie är att utveckla en grupp matematiska modeller som beskriver uppmätta värden och deras utveckling över tid, för en väl fungerande fjärrvärmecentral. FörIn the rise of digitalization, new possibilities are being discovered for district heating in areas like demand side management and fault detection. For these purposes it is necessary to have reliable models describing the substations. In this thesis, the aim is to develop a group of mathematical models to describe measured quantities and their progress through time, for a well performing substati

I psykodynamisk teori och traditionell praxis är en av grundteserna att tidpunkten för terapins slut ska vara en öppen fråga när terapin inleds och sedan beslutas om av terapeut och patient tillsammans. Denna tes står i konflikt med begränsningen till maximalt 25 terapisessioner för psykodynamisk psykoterapi inom Avtal för Psykoterapi i Hälsoval Skåne. Vilka konsekvenser detta får för de terapeuteOne of the basic premises in psychodynamic theory and traditional practice is that the point of closure is left open, and the therapist and patient together decide when the therapy is to end. This conflicts with the limit of 25 therapy sessions stipulated in the agreement between the health authority and psychotherapists, Avtal för Psykoterapi i Hälsoval Skåne. The consequences of this for the the

Existing research acknowledges users as an important external source of innovation for firms, but mainly focuses on user innovation in mature firms. The aim of this paper is to understand why and how startups strategically integrate users in the innovation process. To achieve this purpose we chose an abductive, qualitative research approach and conducted a multiple case study on six Swedish high-t

The purpose of this thesis is to examine how the European Union through its cultural program “Creative Europe” is constructing and promoting a transnational European identity. In the context of humanities and European Studies this can be seen as relevant in the sense it is the study of man as a cultural being, as well as it is stated in Merriam-Webster dictionary “humanities plural : the branches

This thesis investigates whether or not the Chinese growth is sustainable in the longer term. The two major economies China and India share several common features in terms of e.g. growth and size, as well as fundamental differences regarding factors such as institutions and politics. There is a possibility that India, a democratic country, possibly, in the longer time horizon will overtake China

The aim of this study is to analyze the environmental impact of Foreign Direct Investment (FDI) in Sub-Saharan Africa. Over the last decades, increasing levels of environmental degradation have been recorded and Sub-Saharan Africa (SSA) is a region that is particularly vulnerable to these climatic changes. It has been claimed that the environmental degradation, with rising levels of CO2 emission,

Financial distress is costly for a company and affects many stakeholders. Although models of distress and default have been constructed and developed by researchers for a long time, a model adapted to the unique characteristics of the Swedish market is still missing. This study has two major purposes: (1) to construct a model of distress on the Swedish market, and (2) to use this model to investig

Gender Studies departments have struggled to legitimize their own space in the Swedish academia from 70´s. Even when the institutionalization of Gender Studies can be told as a success story, its departments continue to be quite paradoxical spaces in the academia, where the feminist oppositional tendency seems to collide with academic standards and requirements. Additionally, this clash is aggrava

The World Bank is a key actor within development, continuously funding projects on women’s empowerment in countries world-wide; Liberia being one of them. Women and girls have been particularly affected by previous conflicts in Liberia, strongly impinging on their participation in the labor market still today (UN Women 2014). Research shows that one of the foremost issues for women today is the fa

Due to its history, Germany holds a vast number of industrial sites that have long been abandoned and thus, have fallen into oblivion. Albeit their indisputable qualities, they also bear obstacles which entails that greenfield development projects are still dominating Germany’s urban planning processes and the construction industries, thus causing a severe land consumption each day. This project d
