Spallations anläggningar är ämnade för produktion och forskning med fria neutroner. Ett problem uppstår för dessa anläggningar efter att högenergetiska neutroner skapas via en så kallad spallation. Högenergetiska neutroner är problematiska att hålla udner kontroll. På grund av deras höga energi kan dessa neutronerna ``rymma'' och orsaka kärnreaktioner som bidrar till en försvagad signal-upAt European Spallation Source ERIC, 2 GeV proton bunches will be accelerated towards a tungsten target where spallation will occur, producing a wide neutron energy spectrum. Despite the shielding and moderators in place to stop and/or reduce their energy, a significant portion of the most energetic neutrons, called prompt neutrons, might still reach the sample position of a neutron-scattering inst

The music content online is expanding fast, and music streaming services are in need for algorithms that sort new music. Sorting music by their characteristics often comes down to considering the genre of the music. Numerous studies have been made on automatic classification of audio files using spectral analysis and machine learning methods. However, many of the completed studies have been unrealis

Sveriges kommuner har ett stort ansvar för samhällsplaneringen och därmed också för klimatarbetet på lokal nivå. Kommunerna kan genom strategisk fysisk planering av områden såsom bebyggelse, trafikinfrastruktur och energiförsörjning, bidra till att minska utsläppen av växthusgaser. Kommunens översiktsplan är det dokument som på ett strategiskt sätt ska ange inriktningen för den långsiktiga utvecklSwedish municipalities have the responsibility for spatial planning in Sweden and therefore also play an important part in the climate change efforts at the local level. Municipalities can, through strategic planning of areas such as housing, traffic infrastructure and energy supply, contribute to reduction of greenhouse gas emissions. Municipality's comprehensive plans are meant to set the di

This thesis surrounds the emerging of the neoliberal hegemony in Sweden, and how to describe that emergence with the help of an analysis of ideas along with different types of analytic tools such as ideal types and the concept of hegemony. The research question to be answered is that how one can describe the emerging of the neoliberal hegemony in Sweden, which then naturally also makes this thesis

The rapid changes in internet technology, coupled with Web 2.0 have created new and exciting ways of how we interact, socialize, and express ourselves. These new forms of socializations have been highly facilitated by Social Networking Sites (SNSs). These SNSs work as platforms for all types of information and entertainment experiences, creating a distinct culture of consumption of information and

The importance of reading : a Master’s Thesis about literacy and librarians’ motivational reading strategies towards children and teenagers. The public literacy debate has exploded all over Swedish media since PISA published their report at the end of 2013 with the result that politicians, teachers and parents suddenly have shown a lot more interest in what and how young people read. The report h

I detta arbete presenteras en del av den ryggradsdjursfauna som fanns i södra Sverige under krittidens senare del, dvs. för mellan 100 och 66 miljoner år sedan. Vidare avhandlas ett mystiskt, fossilt skelettfynd från Kristianstadbassängen i nordöstra Skåne. Syftet med studien är att identifiera fossilet och att försöka bestämma till vilken djurgrupp det kan ha hört. Benet hittades i grundmarina sThis work presents a part of the vertebrate fauna that existed in the southern of Sweden during the latest Cretaceous period, between 100 and 66 Ma ago. Further, data on a mysterious skeletal finding from the Kristianstad Basin will be presented. The purpose of the study is to identify the fossil and to determine to which group of animals it might have belonged. The fossil was found in shallow, m

While it is fairly certain that people have experienced emotions all throughout history, it is less certain how we understand historical expressions of emotion in a modern context and what value such an understanding could bring to examinations of the link between power and the people. The aim of this master thesis is to gain deeper understanding regarding the relationship between human emotions a

Utgångspunkten i svensk socialvård är att insatser ska ske på frivillig väg. I vissa fall måste dock samhället ha möjlighet att använda tvång mot den enskilde. Ett sådant tillfälle är när barn och unga far illa, antingen på grund av missförhållanden i hemmet, eller på grund av eget beteende, och samtycke till vård saknas. Samhället kan då ingripa med stöd av lag (1990:52) med särskilda bestämmelseThe basic idea for social welfare in Sweden is that the needed interventions are to be initiated on a voluntary basis. However in some particular situations a forced intervention against the individual must be an available way of action for society. One such particular situation is when children and juveniles are put in harms way, either from an abusive domestic situation or from their own behavio

The introduction of new technology in the complex and safety-critical obstetric setting represents a notoriously difficult process. The changes of working practice brought about by a new device can challenge and affect professional boundaries. Consistent with the epistemological pluralism of medical social science research we decided to explore and celebrate the partially overlapping and sometimes

Denna uppsats undersöker effekterna av minimikapitalkravet i relation till svenska privata aktiebolag. Aktiekapitalets ”vara eller inte vara” är något som länge debatterats, i Sverige och utanför. Sverige och många av de kontinentaleuropeiska länderna, såsom Tyskland, har en tradition att kräva att entreprenörer som önskar att starta ett privat aktiebolag bidrar med kapital till detta. Skälen är This thesis aims to clarify the effects of the minimum share capital requirement in relation to Swedish private limited liability companies. The “be or not to be” of a minimum share capital requirement has been debated for a long time, both in Sweden and abroad. Sweden and many of the European continental countries such as Germany has a tradition of requiring that entrepreneurs wishing to form a

Market efficiency in an ex-dividend context is still a disputed matter in the world of finance. Even though numerous articles have been published in the area, with several different approaches, this anomaly is still contested. Overall, the consensus is that the stock price falls less than the dividend amount on ex-dividend day, meaning that there is an excess return to be made at this period. In t

Felicia Ullstad Såphinnor och vattenstrålar Såphinnor är ett väl studerat fenomen inom fysiken. De studeras som ett skolboksexempel på tunnskiktsinterferens och används mycket ofta för att demonstrera att minimering av ytor. Tunna vätskestrålar är också ett välutforskat område, då de kan användas till allt från bestrutning, i bläckskrivare till att skära i stål. Kombinationen av såphinnor och tu

Abstract: Avian long-distance migration as an adaptation to spatiotemporally changing resources is a complex evolutionary trait shaped by various endo- and exogenous factors. Descriptive studies of migratory journeys provide direct investigations of migratory parameters and these often set the basis for fun-damental follow-up studies on the eco-evolutionary principles. In this study, male Great

The shortage of accessible water in the world is especially severe in arid regions, where many are already living to the limits of survival. In such areas, the conditions are in fact getting more extreme due to climate change and a growing population. The share of water is to be distributed for human use, as well as agriculture, which is why irrigation with lower quality water is essential. In add

Densiteten I stadens utveckling utmanar oss arkitekter till att skapa bra arkitektur i stadsrummet. Staden växer och skapar nya förutsättningar i människans vardag. Staden förtätas och då brist på bra centralt placerad mark blir väldigt påfrestande så skapas nya urbana typologier. Jag vill i mitt examensarbete arbeta vidare på denna problematik och undersöka mer specifikt, hur ser bostaden ut i The density of the city’s development challenges us architects to create good architecture in the urban space. The city grows and creates new conditions in people’s everyday lives. The city is densified and when the lack of good centrally located sites becomes very challenging, new urban typologies are created. In my master thesis, I work further on this problem and investigate more on what hous

Automated servo systems are widely used in today’s industry. Therefore, there is high value in improving the reliability and accuracy of these systems and reducing costs. One way to achieve this is to remove the gearbox component, since it typically represents a large fraction of the system’s cost, and it contains many moving parts which will wear and eventually fail. However, removing the gearbox

This study explores how airports develop and repeat specific behaviors that help them remain innovative over time. As digital needs increase, climate regulations tighten, and passengers demand better experiences, airports must remain dependable while also finding ways to adapt. This study examines the behaviors and habits that make innovation a part of everyday work. To further understand this, tw

Production of Hempseed oil results in large quantities of residual Hempseed Press Cake, which has historically been used for animal feed due its unpalatable high fibre content. Through pH extraction and precipitation, the protein contents can be isolated for use in foodstuffs. This project showcases the possibilities of utilizing lactic acid fermentation to aid the process and potentially improve

Elater ferrugineus is a saproxylic click beetle inhabiting old deciduous trees in Europe. It is threatened throughout its area of distribution due to habitat loss. No efficient monitoring method has been available for this species, but observed attraction of females to (R)-(+)-γ-decalactone, which is a male-produced sex pheromone of its prey, the scarab beetle Osmoderma eremita, has led to the dev
