In this thesis the intraday seasonality in the EUR/SEK spot returns are investigated after the returns have been filtered from intraday volatility. This is done with five-minute returns from year 2007 to 2019. The returns are filtered using the Flexible Fourier Form regression and then intraday seasonality is tested using an ARMAX-GARCH model. The results reveal no significant intraday seasonality

Målet med denna uppsats är att bidra med en koncis introduktion till ämnet Galoisteori som kulminerar i ett bevis för olösbarheten av den generella femtegradsekvationen med radikala uttryck. Vidare används den kroppteori som behandlats till att kortfattat diskutera geometriska konstruktioner, där omöjligheten av kubens fördubbling, vinkelns tredelning och cirkelns kvadratur bevisas. Innehållet ochGalois theory unites field theory and group theory to solve some field theoretical problems. The aim of this thesis is to provide a concise introduction to the topic, culminating in the proof of the insolubility of the general quintic equation by radicals. Using the developed field theory, a short discussion about geometric constructions is included, in which the impossibility of duplicating the c

Common for research on trade effects of EU integration is that ascending countries see significant increases in trade. Theory also suggest

Klimatförändringar är idag ett faktum och påverkar både människor och vår omgivning världen över. I Lund i södra Sverige beräknas både mängden och frekvensen av extrema skyfall att öka i framtiden, som konsekvenser av klimatförändringarna, vilket skapar stor risk för översvämningar. Samtidigt växer befolkningen och fler bostäder behövs men när nya stadsdelar byggs så finns det risk för att permeabThe consequences of climate change affect our environment as well as humanity all over the world. For the city of Lund in southern Sweden, climate change consequences are seen as an increase of both intensity and frequency of extreme rain events, which causes an extensive risk for pluvial flooding. Simultaneously, the population and need for housing are growing. When building new districts, the pe

Bakgrund: Att intubera prehospitalt är oftast svårare än intrahospitalt. Prehospitalt behövs hänsyn tas till patientens placering och bristande tillgång till utrustning. Förloras luftvägen oavsett trauma leder det till en snabb förlust av livet. Syftet är att belysa anestesisjuksköterskans kompetensområde och hens upplevelse av att arbeta prehospitalt. Metod: En kvalitativ ansats har använts tillBackground: Prehospital intubation is usually more difficult than intra-hospital. Prehospital needs to take into account the patient's location and lack of access to equipment. Losing the airway regardless of trauma will result in a rapid loss of life. The purpose is to shed light on the Nurse Anesthetist´s area of expertise and her experience of working in a prehospital setting. Method: A qua

Inom det folkrättsliga regelverket för mänskliga rättigheter är förbudet mot tortyr absolut och okontroversiellt. Trots de betydande insatser som gjorts för att bekämpa tortyr, kvarstår det dock som ett allvarligt och utbrett problem, delvis på grund av att faktisk straffrihet förblir vanligt. Universell jurisdiktion har därför identifierats som ett verktyg för att försöka säkerställa straffrättslWithin international human rights law, the prohibition of torture is absolute and uncontroversial. However, despite considerable efforts to end it, torture remains a pervasive problem all over the world, in part due to the widespread impunity for such acts. Many have hence identified universal jurisdiction as one of the ways whereby accountability for torture may be enhanced. The present thesis ex

While carbon emissions hit an all-time high in 2019 and are expected to grow, it is important to explore strategies for reducing emissions and mitigating climate change. A potential focus for curbing emissions is the flying sector, since air travel is one of the most carbon-intensive activities an individual can engage in. Among air travelers, frequent flyers yield the highest potential for saving
