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

Uppsatsen är en case-studie i kommunalt brottspreventivt arbete med fokus på hur kön, ålder och ursprung spelar roll för insatser mot utanförskap. Utgångspunkten är regeringens skrivelse Tillsammans mot brott samt CEMR-deklarationen. Tillsammans mot brott är en regeringsskrivelse som lyfter kommunerna som centrala aktörer inom brottspreventivt arbete och uppmanar kommunerna att samarbeta med polis

This thesis analyses the history and usage of war photography and propaganda according to theories of their utilisation for the establishment of national narratives in times of war. While Western media and nations alike try to establish narratives of just war without loss of innocent people and own soldiers, the newly emerged terrorist group Islamic State indicates a paradigm change in the approac

Human existence depends on a functioning food system; today’s food chain is cracking and alternative foods are being presented to the public. This thesis discusses how future food can be part of a greater discourse of climate change in the Anthropocene. Using three case studies of future food: ‘The Next Menu’, Huel and Project Nourished I investigate how future food is presented and what hidden me

The interdisciplinary field of Comics Studies has developed since the late 20th Century, in response to the increasing, popular reach of comics as a mass phenomenon capable of addressing a wide range of subject matter and approaches, including journalism, (auto)biography, and academical papers. Still, these apparent innovations and, in turn, their scholarly dissemination are predicated upon genre

The project is located in Aden City. Aden is a city in the Yemeni Coastal Plains, on the Gulf of Aden just at the Southern End of the Red Sea. It is a UNESCO World Heritage Site. The city has a desert climate. During the year, there is virtually no rainfall in Aden. The hot weather and the humidity is a big challenge in this kind of cities. The project is a kind of research and a design in climate

Livsmedel är någonting som alla individer konsumerar flera gånger om dagen utan att reflektera över om det man äter kan påverka ens mående och välbefinnande. Det som konsumenten förväntar sig av livsmedlet är att det inte är förorenat eller innehåller mikrobiella, kemiska eller fysikaliska faror som göra en sjuk. De frågor som man som konsument kan ställa sig är: Hur vet livsmedelsföretagen att deThe English title of this master thesis project is ”Risk assessment, hazard analysis and HACCP plan during production of fruit- and berry based products”. As the title refers to, this projects is divided into two part. The first one is the risk assessment of a company’s raw material for their production. The second part is a Hazard Analysis Critical Control Point (HACCP) method that is used to eva

The current thesis presents the results from a neutron reflectometry analysis performed on data collected at ISIS in Rutherford Appleton Laboratories, England, in October 2017. The CRISP instrument was used and the Multi-Blade incorporated as a detector. This was the first attempt ever to use the Multi-Blade in this type of measurement. The Multi-Blade is a cold and thermal neutron detector curren

This thesis investigates the role of the local ICT-sector in Stockholm’s regional development over the last four decades. The inquiry is motivated, on the one hand, by economic polarization in the region and, on the other hand, by the increasing centrality of technical innovation in the region’s development over the last decades. The theoretical background is based on the literature that covers f

It is easy to see that not everyone belongs in the same social circle as those who regularly engage with art and who visit contemporary art museums. I take this as intuitive. In 2017, Ruben Östlund’s film, The Square, garnered tremendous critical acclaim for satirizing the problems in high-end contemporary art culture. In my research, I take these issues seriously, using The Square as a point from

Hur allting började och stora ting har alltid fascinerat människor, och hur mycket större och "i början" blir det än i kosmologi, läran om universums födelse och utveckling? När universum var bara några minuter gammalt var det minst sagt ohyggligt varmt (miljoner grader!). Vi har hyfsad koll på vad som hände vid olika tidpunkter efter de första sekunderna, efter 3 minuter bildades det väThe purpose of this thesis is to study what effect a photon field has on the equations of motion and the decay of a charged scalar field in thermal equilibrium at finite temperature and outside of thermal equilibrium. To do this we calculate the two-particle irreducible effective action for the mean fields and propagators and derive their equations of motion. The functional representations of up t

Stora sektorsövergripande samverkansprojekt har blivit på modet vad gäller att komma tillrätta med ökad segregation inom svenska förorter. För att åstadkomma långsiktig systemförändring förespråkas en omvandling från projektbaserade arbetssätt till strategisk samverkan där förortssituationen möts i hela sin komplexitet. Dessa så kallade wicked problems, som karakteriseras av problemställningar utaCross sector collaborations with multiple stakeholders are on the rise when it comes to dealing with segregation in Swedish suburbs. To achieve long-term systemic change, project-based interventions are slowly giving way to joint initiatives of a more strategic character, which target the situation of the suburbs in all of their complexity. These so-called wicked problems, characterized by problem

Bevisvärdering av barns och vuxnas utsagor har länge varit ett omdiskuterat ämne där rättssäkerheten i domstolens fria bevisvärdering har ifrågasatts. I våldtäktsmål är det vanligt att stödbevisning saknas och att ord står mot ord. Hela åtalet tvingas då bygga på målsägandens utsaga, men hur duktig är egentligen domaren på att avgöra huruvida en utsaga är sann eller falsk? Har domaren den kunskap Evaluation of evidence of children's and adults' statements has, for a long time, been a controversial subject where the legal certainty in the court's free evaluation has been in question. In rape cases it is common that they lack direct evidence. The entire prosecution is then forced to build on the complainant’s statement, but how accurate is the judge in determining whether a state
