Using hydrodynamical simulations of entire galactic discs similar to the Milky Way (MW), reaching 4.6 pc resolution, we study the origins of observed physical properties of giant molecular clouds (GMCs). We find that efficient stellar feedback is a necessary ingredient in order to develop a realistic interstellar medium, leading to molecular cloud masses, sizes, velocity dispersions, and virial pa
The isotopic distribution of nuclei produced in the 50Ti + 249Cf reaction has been studied at the gas-filled recoil separator TASCA at GSI Darmstadt, which separates ions according to differences in magnetic rigidity. The bombardment was performed at an energy around the Bass barrier and with the TASCA magnetic fields set for collecting fusion-evaporation reaction products. Fifty-three isotopes lo
The observation of Higgs boson production in association with a top quark pair (tt¯H), based on the analysis of proton–proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider, is presented. Using data corresponding to integrated luminosities of up to 79.8 fb−1, and considering Higgs boson decays into bb¯, WW⁎, τ+τ−, γγ, and ZZ⁎, the
En central del av vår för-teoretiska förståelse av mänskliga rättigheter är att vi har dem i kraft av att vara människor, vad jag kallar människa-tesen. Genom begreppsanalytiska verktyg diskuterar jag två tolkningar av denna tes: att vi har mänskliga rättigheter i kraft av att tillhöra arten Homo sapiens eller eftersom vi är rationella och autonoma personer. Det finns problem med bägge tolkningarn
The first measurements of anisotropic flow coefficients vn for mid-rapidity charged particles in Xe–Xe collisions at sNN=5.44 TeV are presented. Comparing these measurements to those from Pb–Pb collisions at sNN=5.02 TeV, v2 is found to be suppressed for mid-central collisions at the same centrality, and enhanced for central collisions. The values of v3 are generally larger in Xe–Xe than in Pb–Pb
In modern electronics, device downscaling demands atomic precision control and Atomic Layer Etching (ALE) can provide this prime capability with minute device damage. ALE, also known as layer-by-layer etching, is a technique of removing atomically thin layers from the surface of materials in a controlled way.This technique is now very crucial for nanofabrication and semiconductor industry in order
The purpose of the present study is to understand and clarify how Jesus is presented as a leader in the Gospel of Matthew. The usage of common leadership terms in reference to Jesus early in the story, the biographical genre of Matthew, and the consistently negative portrayal of other leaders in the story give good reasons for the inquiry. Three main questions are at the forefront: How does the th
This paper presents results from a risk assessment of recycling pre-treated bottom ash from municipal solid waste incineration as a subbase layer in certain asphalt paved constructions in Sweden. Based on a model for assessing environmental and health risks at contaminated areas, previously developed by the Swedish EPA and by the Swedish Geotechnical Institute, target values for total content and
The analysis of the virtues of Jesus in the Gospels has not gained a lot of interest in New Testament studies. Some scholars hesitate to use the term “virtue” in reference to Jesus, emphasizing the difference between the NT and the Greek philosophical tradition. Other scholars suggest that the Gospels are not concerned with the character of Jesus, but with his identity as Messiah and Son of God. B
Background: Hand eczema (HE) in healthcare workers (HCWs) is common. Besides wet work, healthcare work also implies exposure to contact allergens. Objectives: To assess HE and contact allergy related to occupational exposures in HCWs. Methods: In a cross-sectional study, 311 HCWs with HE within the preceding 12 months and a control group of 114 HCWs without HE were investigated with the baseline s
Vem avgör vad som är etiskt rätt att göra inom medicin och forskning? Och hur angriper en medicinetiker ett etiskt dilemma? I det här avsnittet möter vi Nils-Eric Sahlin, professor i medicinsk etik vid Lunds universitet och medlem i Statens medicinetiska råd (SMER). Vi pratar bland annat om artificiell intelligens i vården, hur de medicinetiska frågorna sett ut genom historien – och varför majorit
Aim: We studied the impact of maternal and pregnancy-related conditions and the effect of gestational age itself, on the health of infants born late preterm. Methods: Singletons born in gestational weeks 34 + 0 to 41 + 6 in 1995–2013 in the southern region of Sweden were identified from a perinatal register. We found 14 030 infants born late preterm and 294 814 born at term. A hierarchical system
BACKGROUND: Hybrid positron emission tomography (PET)-magnetic resonance imaging (MRI) systems have been taken in use as new clinical diagnostic tools including detection and therapy planning of cancer. To reduce the amount of contrast agents injected in patients while fully benefitting both modalities, dual-modality probes are required.MATERIAL AND METHODS: This study was first aimed at developin
The aim was to evaluate volume, diffusion, and perfusion metrics for better presurgical differentiation between high-grade gliomas (HGG), low-grade gliomas (LGG), and metastases (MET). For this retrospective study, 43 patients with histologically verified intracranial HGG (n = 18), LGG (n = 10), and MET (n = 15) were chosen. Preoperative magnetic resonance data included pre- and post-gadolinium co
PURPOSE: To propose and assess an improved method for calculating the equilibrium magnetization of arterial blood ( M0a), used for calibration of perfusion estimates in arterial spin labeling.METHODS: Whereas standard M0a calculation is based on dividing a proton density-weighted image by an average brain-blood partition coefficient, the proposed method exploits partial-volume data to adjust this
