BACKGROUND: Umbilical cord blood gases are routinely used by midwives and obstetricians for quality assurance of birth management and in clinical research. They can form the basis for solving medicolegal issues in the identification of severe intrapartum hypoxia at birth. However, the scientific value of veno-arterial differences in cord blood pH, also known as ΔpH, is largely unknown. By traditio

BACKGROUND: X-ray micro-tomography (μCT) is a powerful non-destructive 3D imaging method applied in many scientific fields. In combination with propagation-based phase-contrast, the method is suitable for samples with low absorption contrast. Phase contrast tomography has become available in the lab with the ongoing development of micro-focused tube sources, but it requires sensitive and high-reso

We report the discovery of a new planetary system with three transiting planets, one super-Earth and two sub-Neptunes, that orbit EPIC 249893012, a G8 IV-V evolved star (M = 1.05 ± 0.05 M, R = 1.71 ± 0.04 R, Teff = 5430 ± 85 K). The star is just leaving the main sequence. We combined K2 photometry with IRCS adaptive-optics imaging and HARPS, HARPS-N, and CARMENES high-precision radial velocity mea

Background and purpose: Pain is highly prevalent in Parkinson's disease (PD), impacting patients’ ability, mood and quality of life. Detecting the presence of pain in its multiple modalities is necessary for adequate personalized management of PD. A 14-item, PD-specific, patient-based questionnaire (the King's Parkinson's Disease Pain Questionnaire, KPPQ) was designed corresponding to the rater-ba

Within clay prone areas it is important to know if and to what extent quick clay is present. In Sweden undisturbed sampling and laboratory investigations are used to determine clay sensitivity and identify quick clay. Recent research for mapping of quick clay areas with the resistivity method is based on the fact that low pore-water salinity constitutes a criterion for quick clay formation. Electr

Iron’s abundance and rich coordination chemistry are potentially appealing features for photochemical applications. However, the photoexcitable charge-transfer (CT) states of most Fe complexes are limited by picosecond or sub-picosecond deactivation through low-lying metal centered (MC) states, resulting in inefficient electron transfer reactivity and complete lack of photoluminescence. Here we sh

The excited state dynamics of solvated [Fe(bpy)(CN)4]2-, where bpy = 2,2′-bipyridine, show significant sensitivity to the solvent Lewis acidity. Using a combination of optical absorption and X-ray emission transient spectroscopies, we have previously shown that the metal to ligand charge transfer (MLCT) excited state of [Fe(bpy)(CN)4]2- has a 19 picosecond lifetime and no discernable contribution

Recent years have seen the development of new iron-centered N-heterocyclic carbene (NHC) complexes for solar energy applications. Compared to typical ligand systems, the NHC ligands provide Fe complexes with longer-lived metal-to-ligand charge transfer (MLCT) states. This increased lifetime is ascribed to strong ligand field splitting provided by the NHC ligands that raises the energy levels of th

Cold intolerance and pain can be a substantial problem in patients with peripheral nerve injury. We aimed at investigating the relationships among sensory recovery, cold intolerance, and neuropathic pain in patients affected by upper limb peripheral nerve injury (Sunderland type V) treated with microsurgical repair, followed by early sensory re-education. In a cross-sectional clinical study, 100 p

Despite a few reports of photoluminescent and strongly photo-oxidizing transition metal complexes with a d5 electronic configuration, the photophysics and photochemistry of this class of transition metal complexes have largely remained unexplored. Recent investigations of earth-abundant iron(III) N-heterocyclic carbene (NHC) complexes have demonstrated promising photophysical and photochemical pro

Abstract. Purpose: To compare the performance of two machine learning classifiers (MLCs), artificial neural networks (ANNs) and support vector machines (SVMs), with input based on retinal nerve fibre layer thickness (RNFLT) measurements by optical coherence tomography (OCT), on the diagnosis of glaucoma, and to assess the effects of different input parameters. Methods: We analysed Stratus OCT data

Besittningsbegreppet är och har länge varit ett centralt begrepp inom den svenska sakrätten. Begreppet är avgörande i många fall, men saknar trots detta en reell definition. Inom sakrätten är besittning ett viktigt rättsfaktum som både presumerar äganderätt och skänker förfogandelegitimation. Detta märks framförallt när det handlar om tre typiska sakrättsliga problemsituationer: tvesala, godtrosföThe concept of possession is and has long been a central concept of the Swedish property law. Being a crucial and important concept, it has none the less never been fully defined by Swedish law. Possession is an important element of property law; being in possession of personal property means one is presumed to own the property or, at least, use the property. This becomes obvious when one looks at

The phase center is defined as the point on an antenna from which the far field radiation seems to originate. Phase center calculations are often uncertain and vague, and very little concrete information is available on the subject. Recently, a replacement parameter called the radiation center was introduced in [5]. The radiation center is more rigorously defined than the phase center and possesses a

En av de absolut största utmaningarna inom modern fysik är att beskriva beteendet hos system som består av många partiklar eller föremål som alla interagerar med varandra, så kallade interagerande mångkroppssystem. Solsystemet är ett sådant system, där solen, planeterna och alla månar interagerar med varandra genom tyngdkraften. En annan typ av mångkroppsystem är kristaller. En kristall består aThe physics of interacting many-body systems is a very complex and challenging subject. Therefore one in general needs to use simplified models and approximate methods for studying these systems theoretically. In this work we study the exchange-correlation (xc) potential for the Hubbard-Holstein (HH) model for the application of Density Functional Theory (DFT) to the same. The Hohenberg-Kohn theo

The increased use of plastics has become an environmental problem where plastics, due to the slow degradation, accumulate in the oceans and landfills. Although plastics are a very cheap and useful material with desirable properties and a wide variety of applications, they are primarily made from petroleum-based resources which are non-renewable and of fossil origin. An alternative to these non-ren

Sverige står i dagsläget inför en brådskande energiomställning. Fossila bränsle skall fasas ut till 2045, landets kärnkraftsproduktion reduceras stadigt och samtidigt ökar energibehovet i takt med landets elektrifiering. Sverige har dock potential att miljövänligt och självständigt täcka upp för dessa avkall. Tilläget till vind- och solenergi heter Enhanced Geothermal Systems (EGS). EGS-tekniken mThe ability to evaluate the geothermal potential at a depth of five to six kilometres in the crystalline bedrock is crucial for the EGS-technology to be utilized in the future. This work focuses primarily on presenting expected geological conditions at great depths in southwestern Scania. The study is based on information from E.ON’s deep drilling FFC-1 in Malmö and data and investigations of the

Hur kan restmaterial från stålindustrin användas för att minska uttaget av naturresurser? Ett vanligt användningsområde av exempelvis stålslagg är som konstruktionsmaterial vid sluttäckning av deponier. Genom att använda slagg för detta ändamål kan mängden deponerat material minska, samtidigt som man kraftigt minskar behovet av vanligt täckmaterial, såsom grus och jord. Stålslagg kan även användasA variety of excess material is produced in the processes used in the scrap-metal based steel industry. The largest stream of material, by volume, is steel slag. Since slag material has very different properties and wide differences in its chemical composition its usage can be found in different sectors. The increased understanding of slag and its properties has made companies less prone to divert
