Air pollution in urban environments exhibits large spatial and temporal variations due to high heterogeneous air flow and emissions. To address the complexity of local air pollutant dynamics, a comprehensive large-eddy simulation using the PALM model system v6.0 was conducted. The distribution of flow and vehicle emitted aerosol particles in a realistic urban environment in Malmö, Sweden, was stud
Background/introductionFlecainide is a commonly used efficient antiarrhythmic drug against atrial fibrillation (AF). P-wave indices reflect the atrial substrate and can predict incident AF, but their role as predictors of treatment outcomes for flecainide-treated AF patients are unknown.PurposeTo assess if P-wave indices can predict efficacy outcomes in long-term flecainide treated AF patients.Met
BACKGROUND: The management of febrile infants aged ≤ 60 days and adherence to guidelines vary greatly. Our objective was to describe the process of decision-making when managing febrile infants aged ≤ 60 days and to describe the factors that influenced this decision.METHODS: We conducted 6 focus group discussions with 19 clinically active physicians in the pediatric emergency departments of 2 univ
Solar cells based on silicon are successfully harvesting solar energy in established and increasingly widespread solar panels. However, their efficiency is limited by the Shockley–Queisser limit. For certain applications where high efficiency is the key figure of merit, the use of multi-junction solar cells is desirable.III–V multi-junction solar cells exhibit the highest efficiencies achieved to
Use of medical devices (MDs), that is, glucose sensors and insulin pumps, in patients with Type 1 diabetes mellitus (T1D) has proven an enormous advantage for disease control. Adverse skin reactions from these MDs may however hamper compliance. The objective of this study was to systematically review and analyse studies assessing the prevalence and incidence of dermatitis, including allergic conta
X-ray diffraction is an invaluable tool in the field of structural dynamics. In the work described in this thesis, time-resolved X-ray diffraction experiments were carried out to investigate ultrafast lattice dynamics. Ultrashort laser pulses were used to induce non-thermal melting and large-amplitude strain waves, and X-rays were used to probe these phenomena. Non-thermal melting was studied in i
High resolution observations with ALMA have revealed that concentric rings and gaps are common features in protoplanetary disks. The favored mechanism for creating these substructures are planet-disk interactions, in which growing planets open gaps in the disk, and particles become trapped at the pressure maxima that form at the corresponding gap edges. Since the particle density in these pressure
Skogen är bäst på bild is an electroacoustic text-sound-composition work; it could also be considered a radiophonic work. This was the first work of text-sound composition I ever made, repurposing that more abstract genre here as a direct tool for finding memory and identity in the city. Although Stockholm’s history of text-ljud-komposition (text-sound-composition) is something I have engaged with
The aim of this study was to investigate how people who have been on sick leave due to fatigue syndrome, reason about the interaction with authorities, the employers and health care, and how they describe their experiences of the sick leave procedure and their way forward from there. We conducted a qualitative study with nine semi-structured interviews. For our theoretical approach we applied the
Ribonucleotide reductases (RNRs) are important enzymes that convert the building blocks of RNA (NTPs) into building blocks of DNA (dNTPs). dNTPs are used for synthesis of DNA as well as repair of mutated and damaged DNA. These cellular processes are critical to an organism. That is why these processes are found in various organisms. Since these processes are so essential, their allosteric regulati
För att minska miljöpåverkan och minimera exploateringen av de begränsade tillgångar som finns så krävs en övergång till cirkulär ekonomi. Det innebär minskad materialkonsumtion och mer återanvändning och återvinning av plast och andra material. Förra året producerades i världen 359 millioner ton plast och av det insamlade avfallet i Europa blev endast en tred-jedel återvunnet. Bland de fem mest pTo reduce the environmental impact and minimize the exploitation of the depleting re-sources, the transition to a circular economy is vital. It proposes an economy of reduced ma-terial consumption and increased reuse and recycling of plastics and other materials. Only last year, 359 million tonnes of plastic were produced worldwide and only a third of the col-lected waste in Europe was recycled. A
Is the management of Type 1 Diabetes best left to the medical sciences, or do the social sciences have a stake as well? In ‘Sweet Blood Surveillance,’ I push back against the perceived domination of scientific objectivity to make space for the subjective experience of diabetes in the maintenance of glucose levels through a collaboration with medical technical objects. To accomplish my task, I crea
Ten per cent of the population in the western world suffer from osteoarthritis – a widespread endemic disease that is estimated to cost the Swedish society equivalent to two per cent of the Swedish GNP annually, corresponding to over 50 billion SEK in 2009 in treatments and lost productivity. With an increasing aging population the incidence of osteoarthritis is expected to be further enhanced. In
Syftet med uppsatsen är att undersöka hur Sverige kom att få fri abort genom att redogöra för argumentationen som fördes under riksdagsdebatten år 1974 gällande införandet av den nya abortlagen. Det görs genom rättshistorisk metod och materialet som har använts är främst riksdagsprotokollen från debatten. För att sätta in riksdagsdebatten i sitt sammanhang berör uppsatsen även kort en överblick The purpose of this essay is to investigate how Sweden got free abortion by examining the arguments made during the parliamentary debate in 1974, which concerned the legislation of free abortion. This is done using a legal historical method and the material that has been used consists mainly of the protocols from the debate. To put the debate in its context the thesis also gives an overview over
The control of large and complex systems is a difficult but important topic. In applications, centralized control, in which all measurements about a system are used to compute control actions, is often preferable, since it allows for a better overview of the system and more precise control. However, in large networks, where the complexity of implementing a centralized controller becomes too diffic
Gräsrotsfinansiering är ett relativt nytt digitaliserat finansieringsalternativ, som växer snabbt både på den svenska och den globala marknaden. Gräsrotsfinansieringsplattformarna syftar till att förmedla kontakten mellan kapitalsökande bolag och investerare. Den snabba tillväxten har dock bidragit till att lagstiftningen har hamnat efter, vilket antas ha påverkat investerarna på plattformarna negCrowdfunding is a new digitized alternative to find capital, compared to other traditional financing methods. The process involves a platform that simplifies for capital seeking companies to find investors. During these past years, the growth of crowdfunding has increased significant, but the legislation hasn’t followed the process. This assumed to have a negative impact on the investors of the pl
Financial crises are recurring phenomena and studying how economic parameters affect outcome and recovery processes will most likely remain an area of intense research also in the years to come. The scope of this paper circulates around the causes and effects of two crises in the period 1985-2013 and their separate effects on the economies of Denmark, Sweden and Finland. Moreover, the main variabl
Global wind power capacity has greatly increased in the last decades and is in certain areas constituting a significant share of generating capacity. This thesis examines wind power production data along with prices and inter-regional trade volumes on the Nordic electricity market Nord Pool Spot to deduce the effects of wind power on the grid. The research focused on Denmark, since it gets a very
I started with the intentions to design a toy. Many of the values I wanted to emphasize are part of or could be applied to the soap-box cart. A traditional soap-box cart is built by hand from bought or collected (left-over) parts and materials. The creation plays a major part in the soapbox concept and I wanted to preserve this. My challenge was to revive the old soap-box cart and adapt it to the
