When it comes to determining the jurisdictional reach of VAT two principles are used by the OECD, EU policy makers and scholars, namely, the origin principle and the destination principle. These principles can mean different things. One problem is that different constructions thereof can result in confusion in the communication between legal actors and, more importantly – in different legal outcom
Dissatisfaction with the current market for scientific publishing, dominated by a few large publishers able to obtain high subscription fees, gave birth to the Open Access movement. One problem for the Open Access movement, which aims at making research results freely available, is that scientists are reluctant to publish in journals that are free on the Internet, so called Open Access journals. T
The purpose of the numerical study was to investigate the influence of three different natural gas compositions on the combustion behaviour of an Advanced Environmental Vortex (AEV) burner. The flow conditions apply to the AEV burners installed in the Siemens gas turbine SGT-800. Numerical simulations were carried out using the software Chemkin 4. Ignition temperatures, adiabatic flame temper
It is very common nowadays to speak of an ''information society'' in which control of information or information based knowledge has replaced control over matter as an ultimate source of economic power. The intellectual creations protected through patents, trade marks, copyrights etc constitute often a huge part of the companies' intangible assets. For example, the value of the
We realize strongly confined quantum dots (QDs) in InAs nanowires (NWs) by combining epitaxial crystal-phase control with chemical wet etching. A strong axial confinement is first introduced by growing closely spaced wurtzite (WZ) tunnel barriers in NWs to enclose a zinc blende (ZB) QD. The NW cross-section is then reduced by isotropic etching to obtain very small QDs, with a maximum observed char
BackgroundShock is a condition with high mortality even with early intervention and treatment. Usual care for shock and hypotension in the Emergency Department (ED) is intravenous fluid resuscitation which can lead to fluid overload and other complications. When fluid therapy fails or risk of complications are high, the next treatment step is the use of vasopressors for stabilisation. Noradrenalin
Objective: To describe the clinical and ultrasound characteristics at the time of diagnosis of primary ovarian immature teratoma with no other germ cell tumor components described on histopathology. Methods: This was a retrospective study of women with a histological diagnosis of primary ovarian immature teratoma who had undergone a preoperative ultrasound examination between 1998 and 2024. Cases
Background Pulmonary nodules (PNs) are clinically challenging because differentiation between benign and malignant PNs is not possible at CT detection; recurring CT examinations and invasive procedures are often required in PN follow-up. Purpose To investigate PN prevalence in a middle-aged population and the risk factors associated with these nodules. Materials and Methods In this secondary analy
This study analyzes the temporal evolution of the short-term P-wave morphological variability (PWMV) within the one-hour interval immediately preceding the onset of atrial fibrillation (AF) episodes. This PWMV is hypothesized to be an index of vulnerable atrial substrate, allowing to identify instability increases preceding the AF episode onset. We analyzed 32 ambulatory ECG recordings from subjec
During the 2015–2018 data-taking period, the Large Hadron Collider delivered proton-proton bunch crossings at a centre-of-mass energy of 13 TeV to the ATLAS experiment at a rate of roughly 30 MHz, where each bunch crossing contained an average of 34 independent inelastic proton-proton collisions. The ATLAS trigger system selected roughly 1 kHz of these bunch crossings to be recorded to disk. Offli

The conversion of technical lignin into valuable chemicals is important for the complete utilization of lignocellulose. The kraft process dominates the pulp industry, and large amounts of kraft lignin are produced worldwide. However, the complexity of lignin limits its valorization. In this study, a kraft lignin, Indulin AT, was depolymerized under base conditions, and the effects of substrate loa

Oats (Avena sativa) are part of the cereal whole grain family, and their production is on the rise for the past few years due to extensive research done on the health benefits it can provide to humans. ScanOats project in Sweden is one of the research groups across the world that has done extensive work on oats. The lines CT-BG-53, CT-BG-21, and CT-BG-37 are mutant lines harvested by Crop Tailor A
BACKGROUND: In order to determine myocardial salvage, accurate quantification of myocardium at risk (MaR) is necessary. We present a validated novel automatic segmentation algorithm for quantification of MaR by myocardial perfusion SPECT (MPS) in patients with acute coronary occlusion. METHODS AND RESULTS: Twenty-nine patients with coronary occlusion were injected with a perfusion tracer before re
During Subzero project there were observed some differences between different manikins. In order to study the differences closer complementary measurements were carried out on 2 manikins representing male and female body shapes. Comparison was carried out based on: • tight versus loose clothing; • serial versus parallel calculation model; • even versus uneven clothing (insulation) distribution; •
Popular Abstract in Swedish Det blir allt vanligare att man ersätter förlorade och skadade kroppsdelar med ett biomaterial (vanligtvis ett metall eller polymer implantat). Exempel på vanliga användningsområden är; suturer, kärl, hjärtklaffar, pacemakers, katetrar, ledproteser, fixationsskruvar för skelett och konstgjorda tänder samt kapslar för långsam frisättning av medicin. Trots det rutinmässigThe biological response to different implanted biomaterials vary. The relative importance of factors in the material and host for this variation are at present incompletely known. The variation in the cellular response to specific proteins and the rapid adsorption of proteins to surfaces exposed to biological environments has created the hypothesis that the cellular interactions with biomaterials
This study investigated cold weather safety footwear and the possible thermal effects of steel toe caps in footwear. Two boot models were manufactured and used in two variants - with (As and Ws) and without (An and Wn) steel toe cap. The boot insulation was measured with an artificial, heated foot (AHF). Experiments with 6 male subjects with boots Ws and Wn consisted of sitting for 60 minutes at -
High-sensitive multi-species detection around 1550 nm using a modulated grating Y-branch, MG-Y, diode laser tunable between 1529 nm and 1565 nm is presented. The MG-Y diode laser is based on the Vernier effect of two modulated gratings, and exhibits quasi-continuous tuning over 36 nm. Multi-species detection is achieved by fast sequential scanning of single absorption lines of CH4, CO, C2H2, and C
An incorrect, superficial suckling technique in breastfeeding frequently leads to milk congestion and sometimes mastitis. In the present study we have examined whether milk congestion may affect levels of the atypical opioid beta-casomorphin-8 in milk and in plasma. We also investigated whether the rate of acute psychosis during the first half year after parturition has declined in Sweden over the
