Efter förstörelsen av städerna Hiroshima och Nagasaki 1945 började en kapprustning mellan Soviet Unionen och USA. För att undersöka inverkan av dessa bomber var testsprängningar nödvändiga. Konsekvensen av atmosfäriska provsprängningar av kärnvapen är att enorma mängder av så kallat kol-14 produceras, vilket är en typ av isotop till kol. Då de atmosfäriska sprängningarna till stor del stoppades 19Radiocarbon dating of human tissues has great potential in medical applications. A consequence of the complex path of radiocarbon to humans through diet is that the radiocarbon content of samples from human subjects is not directly comparable with the atmosphere's. By considering the harvest seasons in Sweden and its surrounding countries, a new software was developed to further investigate if

Uppsatsen tar avstamp i den samtida hudvårdstrenden som hyllar hälsosam, naturlig och ”glowy” hy. Baserat på bl a intervjuer genomförda under våren 2018 återger jag unga hudvårdsintresserade och icke-vita kvinnors subjektiva upplevelse av hud/hudvård; på det individuella planet som vardaglig ritual och på det sociala planet som hudvårdskultur på sociala medier. Ansiktshuden fungerar som symboliskt

Research suggest that foster children’s school achievements in compulsory school are worse compared with their peers in the same age group. The purpose of my study was to explore and analyze what kind of support and assistance foster children are offered in order to leave the compulsory school with approved grades. Furthermore, the aim was also to explore what kind of sup¬port that the social serv

The current study is a case study in which we explore insurance companies’ investigative work by looking at cases of fraudulent arson in motor vehicles. Through interviews with people in the insurance industry, as well as representatives from the police and justice system, we examine the practices and realities of insurance investigations, and by analyzing verdicts from Swedish district courts in

This thesis applies the GARCH-MIDAS model to investigate the effects of macroeconomic variables, sentimental indicators, and financial variables on Swedish stock market volatility for the period January 2002 to December 2016. The GARCH-MIDAS framework allows the incorporation of data at different frequencies into the same model and decomposes volatility into two components. A short-term component

I syfte att få en bild av subjektiva upplevelser av självet hos personer med schizofreni intervjuades fyra personer som är eller har varit diagnostiserade med schizofreni och/eller har upplevt återkommande psykotiska episoder. Självet definierades utifrån the minimal self som innebär en omedelbar, upplevelsemässig realitet, och schizofreni som en störning i självet snarare än närvaro och utbredninIn purpose of gaining insight into subjective experiences of the self in people with schizophrenia, four people, who have or have had schizophrenia and/or have experienced recurring psychotic episodes, were interviewed. The self was defined as the minimal self which has an immediate experiential reality, and schizophrenia as a self-disorder rather than presence and prevalence of psychotic symptoms

Background: Omni-channel retailing has led to customers becoming more demanding and less tolerant than before. For instance, customers are demanding shorter delivery times, and higher precision in deliveries. Unless retailers adapt to an omni-channel approach today, their business is likely to suffer. To do so, more efficient planning of the supply chain is necessary. The first step of the plannin

The building industry in Sweden is dominated by concrete today. However, this material has a greater impact on carbon emissions compared to wood. By examining some of the general properties of wood and specifically cross laminated timber we have explored the basic advantages and disadvantages of this relatively new and mildly used building material, as well as, investigated why it has not develope

The mobile telecommunication network is growing year after year and it will soon move into the high speed 5G and Internet of Things technology. These new technologies will improve the throughput and data connectivity and due to that the energy consumption in radio and digital units may increase in a Radio Base Station (RBS). There are more than 500 000 off-grid RBSs in the world which are powered

Today, the world contains an unimaginably massive amount of digital information, increasing ever so rapidly and bringing about a wide range of opportunities across industries such as predicting future trends, combating crime to name a few. As a result, more and more organi-sations are investing heavily in Business Intelligence (BI) with the hope of gaining insights through data and analytics and h

Att kunna ändra egenskaperna hos nanotrådar till specifika applikationer är viktigt om nanotrådar ska kunna inkorporeras i elektronikindustrin. Bandgapet är en sådan egenskap som för ternära III-V halvledare kan ändras om "ordning" uppstår i materialet. Med ordning menas här att de ingående komponenterna spontant lägger sig periodiskt längs med en kristallografisk riktning. Ett steg mot The ability to tailor the properties of nanowires exactly to fit a specific application is important if nanowires are to be useful and incorporated into the electronics industry. The bandgap is one such property, which, for ternary III-V semiconductors, can be altered by the presence of ordering. In this sense, ordering is referred to as a spontaneous modulation of the ingoing components along cer

The importance of sterilization processes has been a major topic in the food manufacturing industry since it preserves the quality and provides longer shelf-life by preventing microbiological recontamination of products. Aseptic packaging is an alternative technique to pack commercially sterile products into containers with a very low recontamination rate, thus, the entire production chain must be

I dagsläget utförs fullskaliga kapacitetsprov på sprinkleranläggningar med syfte att undersöka om erforderligt tryck och flöde kan erhållas i händelse av brand. Fullskaliga kapacitetsprov är däremot relaterade till risker som lågt tryck i vattenledningsnät, blödning på gjutjärnsrör, översvämning av lågt belägna områden och tryckslag i rör. I detta arbete undersöks om reducerade kapacitetsprov sammTo this date, full-scale capacity tests are performed in sprinkler facilities in order to investigate if sufficient pressure and flow can be achieved in case of fire. Full-scale capacity tests may, however, cause problems such as low pressure in pipes, scaling of pipe walls, flooding of low topography areas, and water hammer. This report intends to research whether reduced capacity tests together

This project has been about understanding the public furniture market from a designers perspective and to develop a competitive design concept based on the needs of different stakeholders in the field of outdoor public products. The research has been mainly in forms of interviews and observations with a focus on Stockholm as geographical scope. I chose to focus on one city as the structure and r

Within the cultural imaginary of video games, armed conflicts have always occupied a central space. Their subject material, as well as technologies and visual techniques, are often based on historical and present-day conflicts, often involving US Armed Forces, subcontractors or intelligence agents. US actors and interests disproportionally occupy the privileged position of protagonist, which has c

På senare år har ökad konkurrens och kapitalmigration från aktiv till passiv förvaltning ställt krav på förnyelse inom kapitalförvaltningsbranschen för att behålla lönsamheten. Adaptiv tillgångsallokering (ATA) har presenterats som ett flexibelt och innovativt alternativ till traditionella metoder såsom strategisk tillgångsallokering. Allokeringsmetoden kombinerar en momentumstrategi med portföljv

This study investigates the negative effects generated from the nexus of financial development and economic growth. Through recent years have the financial sector escalated in ‘speed’ due to the high levels of financial integration which have in turn caused an effect of ‘too much finance’. The effect has been notice in the constant increase of property prices and hence private debt. In order to an

This paper studies the relationship between financial development and economic growth. Specifically, the model tests if financial development has a positive effect on capital accumulation and total factor productivity. The study is based on data from 114 countries between 1960 and 2010. The data include a broad variety of countries, ranging from low-income to high-income countries. Following from
