Objective: The novel axial flow left ventricular assist device HeartMate II was introduced into clinical practice in Europe as part of the pilot study and after CE approval in November 2005. In order to get an overview of the use and performance of the device in Europe a group of investigators was founded to compare the initial results. Methods: In a retrospective analysis of the first 101 consecu
In many materials it remains a challenge to reveal the nature of magnetic correlations, including antiferromagnetism and spin disorder. Revealing the spin structure in magnetic nanoparticles is further complicated by the large incoherent neutron scattering cross section from water adsorbed at the particle surfaces and by the broadening of diffraction peaks due to the finite crystallite size. Moreo
Introduction: Rheumatoid arthritis (RA) is a chronic, inflammatory, and systemic disease with symptoms that limit activities and affect quality of life. RA is associated with an increased risk of developing comorbidities, some of which are also known to be associated with lifestyle habits such as physical activity, diet, smoking, and alcohol. There has been an augmented focus on the implementation
An experimental study on the duration of load effects in a glued shear plate dowel joint was conducted. The joint design features a single large diameter dowel for load transfers between members, via external steel plates, which are bonded to the timber with a low stiffness bond line. Due to the low bond line stiffness, the timber element is subjected to a close to uniform shear stress distributio
During protein crystallization and purification, proteins are commonly found in concentrated salt solutions. The exact interplay of the hydration shell, the salt ions, and protein-protein interactions under these conditions is far from being understood on a fundamental level, despite the obvious practical relevance. We have studied a model globular protein (bovine serum albumin, BSA) in concentrat
Spark ablation is an established method for generating aerosol nanoparticles. By changing the electrodes, synthesis of monometallic, multimetallic and semiconducting nanoparticles has been demonstrated. Apart from using electrodes of specific composition, compositional tuning of bimetallic nanoparticles during synthesis has recently been demonstrated (Kohut, et al., 2021). In many applications, it
Tundra soils account for 50% of global stocks of soil organic carbon (SOC), and it is expected that the amplified climate warming in high latitude could cause loss of this SOC through decomposition. Decomposed SOC could become hydrologically accessible, which increase downstream dissolved organic carbon (DOC) export and subsequent carbon release to the atmosphere, constituting a positive feedback
An experimental investigation has been performed where the influence of metal salts on soot formation has been studied. By combining two-dimensional laser-induced incandescence (LII) and elastic light scattering (ELS), two-dimensional information could be obtained on soot properties in the flames. For these studies, seven metal salts (NaCl, MgCl2, AlCl3, KCl, CaCl2, FeCl3 and ZnCl2) were dissolved
The Cherenkov Telescope Array (CTA), will be the major global observatoryfor very high-energy (VHE) gamma-ray astronomy over the next decadeand beyond. The scientific potential of CTA is extremely broad: fromunderstanding the role of relativistic cosmic particles to the search for darkmatter. CTA is an explorer of the extreme universe, probing environmentsfrom the immediate neighbourhood of black
The Gaia-ESO Survey is a public spectroscopic survey that targeted ≲105 stars covering all major components of the Milky Way from the end of 2011 to 2018, delivering its final public release in May 2022. Unlike other spectroscopic surveys, Gaia-ESO is the only survey that observed stars across all spectral types with dedicated, specialised analyses: from O (Teff ∼ 30 000-52 000 K) all the way to K
This paper performs a numerical study regarding the effects of different kinds of coolants on flow and heat transfer in a pin-finned internal channel. A new pin-fin structure detached from one endwall with a round-tip is proposed which aims to increase the heat transfer enhancement. As a contrast, the investigation of the typical fully-attached pin-fin and the flat-tip detached pin-fin is also con
Background: Osteoporosis is an underdiagnosed and undertreated disease worldwide. Recent studies have highlighted the use of simple vertebral trabecular attenuation values for opportunistic osteoporosis screening. Meanwhile, machine learning has been used to accurately segment large parts of the human skeleton. Purpose: To evaluate a fully automated deep learning-based method for lumbar vertebral
Background: Limited data exist of tracking and changes in accelerometer-measured physical activity in children. Methods: Physical activity was assessed by accelerometers for 4 days in 167 children (boys, n = 90; girls n = 77) age 9.8 ± 0.6 years. Follow-up measurement was made 2.0 ± 0.1 yrs later (range 1.9-2.1 yrs). General physical activity (GPA) was defined as mean count/minute. Minutes of inac
Background: The European Colonoscopy Quality Investigation (ECQI) Group aims to raise awareness for improvement in colonoscopy standards across Europe. We analysed data collected on a sample of procedures conducted across Europe to evaluate the achievement of the polyp detection rate (PDR) target. We also investigated factors associated with PDR, in the hope of establishing areas that could lead t
Salinisation is a global issue which leads to desertification and soil degradation and exposure to salt is also known to inhibit microbial activity and plant growth. This study was conducted to determine the influence of salinity on microbial activity of a non- saline soil. By using Salt Induced Community Tolerance (SICT) concept I found that microbial community tolerance to salt can be induced in
In Europe, sustainability in the meat and dairy industry has emerged as an issue of great concern for society. Research and pressure centre on the agricultural component and little attention has been given to the processing industry despite the integral role it plays in the European meat and dairy supply chain. This thesis aims to fill this knowledge gap by identifying the current sustainability p

Enligt den så kallade korrigeringsregeln i 14 kap. 19 § IL följer att när ett re-sultat av en näringsverksamhet blir lägre, till följd av att villkor som avtalats avviker från vad som skulle ha avtalats mellan sinsemellan oberoende nä-ringsidkare, ska resultatet beräknas till det belopp som det skulle uppgått till om sådana villkor inte funnits. Bestämmelsen är ett uttryck för en internation-ellt Chapter 14 § 19 of the Swedish income taxation act, also known as the “cor-rection rule”, states that when the result of a business is lower than it should be because a contractual term deviates from what would be the contractual terms between independent businesses, the result shall be calculated as if such contractual terms did not exist. The rule is a manifestation of the international-ly recog

Om någon vill ändra användningen av en byggnad, bygga till eller bygga nytt krävs oftast bygglov. Beslut om bygglov fattas av byggnadsnämnden. Om den sökta åtgärden vidtas utanför detaljplan skall alltid sakägare höras och ges tillfälle att yttra sig. Om den sökta åtgärden verkställs inom detaljplanerat område behöver detta endast ske om åtgärden innebär en avvikelse från detaljplanen. ExamensarbTo change the features of a existing building or to build a new building a building permit is needed. The building department at the municipality decides about building permits. The building departments inspection of the applied building permit are a public law inspection and are limited by the Planning and Building Act. Civil rights as ownership and easements are not to be included in the buildin
