Popular Abstract in Swedish Många forskningsprojekt inom materialvetenskap, medicin eller grundläggande fysik kräver smala strålar av laddade partiklar som fungerar som provtagare för att undersöka materiens egenskaper. Dessa partiklar kan vara protoner, elektroner lättare joner. Relativt ofta, behöver de accelereras nästan upp till ljusets hastighet för att kunna tränga in tillräckligt djupt i prLaser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the

Diagnosis and risk stratification of patients with acute coronary syndromes can be improved by adding information from the depolarization phase (QRS complex) to the conventionally used ST-T segment changes. In this study, ischemia-induced changes in the main three slopes of the QRS complex, upward (I-US) and downward (I-DS) slopes of the R wave as well as the upward (I-TS) slope of the terminal S

Bioethanol has received increasing attention as an alternative to petrol due to the current dependency on supplies from other countries and due to the increased concentration of the greenhouse gas carbon dioxide in the atmosphere. In this thesis, the development of 2nd generation production processes for bioethanol production from the lignocellulosic part of biomass is discussed. The conversion of

BACKGROUND: An increasing incidence of penicillin-resistant Streptococcus pneumoniae (PRP) was detected in Malmo in 1994. OBJECTIVE: To evaluate clonality and factors facilitating the spread of PRP among children in day-care centers (DCCs). METHODS: We used phenotypic and DNA-fingerprinting methods in conjunction with epidemiologic data from the South Swedish Pneumococcal Intervention Project's in

Objective and Background: Pulse wave amplitude (PWA) derived from the digital vascular bed has been used in sleep studies. The nocturnal attenuation of PWA has been shown to reflect sympathetic activation during sleep. We assessed the relationship between nocturnal PWA attenuation and office blood pressure (BP). Methods: Eighty-one subjects (46 men; age 60 7 years: body mass index [BMI] 28.2 +/- 4

BACKGROUND: Our recently reported finding of rapid bi-exponential elimination of free prostate-specific antigen (PSA) after radical retropubic prostatectomy in patients with moderately elevated PSA levels, which contrasted a very slow, linear elimination of PSA complexed to alpha-1-antichymotrypsin (ACT), prompted us to study whether these elimination rates were applicable for patients selected fo

Background: The role of antioxidants in the pathogenesis of type 2 diabetes is uncertain. Objective: We evaluated cross-sectional relations of dietary intakes and plasma concentrations of antioxidants with glucose metabolism in a high-risk population. Design: The subjects, were 81 male and 101 female first- and second-degree, nondiabetic relatives of patients with type 2 diabetes. Antioxidant inta

Object: To present population-based and age related incidence of surgery and clinical outcome for adult patients operated for hydrocephalus, registered in the Swedish Hydrocephalus Quality Registry (SHQR). Methods: All patients registered in SHQR during 2004–2011 were included. Data on age, gender, type of hydrocephalus and type of surgery were extracted as well as three months outcome for patient

An improvement in our process-based understanding of carbon (C) exchange in the Arctic and its climate sensitivity is critically needed for understanding the response of tundra ecosystems to a changing climate. In this context, we analysed the net ecosystem exchange (NEE) of CO2 in West Greenland tundra (64°N) across eight snow-free periods in 8 consecutive years, and characterized the key process

Background and purpose - Osteoarthritis (OA) imposes a substantial burden on individuals and societies. We report on the burden of knee and hip OA in the Nordic region. Patients and methods - We used the findings from the 2015 Global Burden of Diseases Study to explore prevalence, years lived with disability (YLDs), and disability-adjusted life-years (DALYs) of OA in the 6 Nordic countries during

Since 2018, the Swedish housing market has exhibited a paradoxical development in which a persistent housing shortage coexists with increasing vacancies. The simultaneous progression of these seemingly anti-correlated trends raises important questions regarding the functioning of the residential real estate sector. This thesis examines why the residential Swedish rental market continues to produce

Transient electromagnetic (TEM) is an efficient non-invasive method to map electrical conductivity distribution in the subsurface. This paper presents an inversion scheme for 3-D TEM time-lapse (TL) data using a generalized minimum support (MS) norm and its application to monitoring conductivity changes over time. In particular, two challenges for TL TEM applications are addressed: (i) the survey

Background: We aimed to evaluate cumulative occurrence and impact of COVID-19 in patients with chronic respiratory failure (CRF) treated with long-term oxygen therapy (LTOT). Material and methods: Data were obtained from the SCIFI-PEARL study on the entire Swedish population and on patients with oxygen-dependent CRF and no COVID-19 diagnosis before start of LTOT. Analyses were performed for three

Hybrid e-learning offered flexibility for students who could not attend in-person classes during the COVID-19 pandemic, but its effectiveness in teaching chest physiotherapy remains to be determined. This retrospective case-control study assessed physiotherapy students’ academic performance and satisfaction with a hybrid classroom approach adopted during the COVID-19 pandemic for teaching airway c

Governance issues surrounding technologies are profound. This is best illustrated in the context of climate change that does not only exert severe, pervasive and multifaceted impacts on the environment and on the everyday lives of people around the world, but also further aggravates the tension between law, technology and the public in a broader societal context. As a response to feckless global a

Context.Gaia's third data release provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than 5 million targets. When combined with the astrometric data, these allow us to derive orbital and stellar parameters that are key to understanding the stellar populations of the Milky Way and to perform Galactic archaeology. Aims. We used the calibrate
