Standing wave ambient pressure photoemission spectroscopy (SWAPPS) is a promising method to investigate chemical and potential gradients across solid-vapor and solid-liquid interfaces under close-to-realistic environmental conditions, far away from high vacuum. Until now, these investigations have been performed only near room temperature, but for a wide range of interfacial processes, chief among

The timing and connections between global cooling, marine redox conditions, and biotic turnover are underconstrained for the Late Ordovician. The second most severe mass extinction occurred at the end of the Ordovician period, resulting in ~85% loss of marine species between two extinction pulses. As the only “Big 5” extinction that occurred during icehouse conditions, this interval is an importan

The late Cambrian Steptoean positive carbon isotope excursion (SPICE) represents a major perturbation to the global carbon cycle and was associated with trilobite extinctions and expansion of anoxic and/or euxinic water masses during episodes of eustatic sea-level change. We present a new Re-Os age together with Os and Nd isotope stratigraphy and major and trace-element data from the Alum Shale Fo

OBJECTIVE: We previously performed a population-based mass screening of coeliac disease in children aged 12 years in two birth cohorts resulting in 296 seropositive children, of whom 242 were diagnosed with coeliac disease after duodenal biopsies. In this follow-up study, we wanted to identify new cases in the screening population that tested negative-either converting from potential coeliac disea

Introduction Differences in birthweight are often seen between migrants and natives. However, whether migrant-native birthweight inequalities widen, narrow or remain persistent across generations when comparing the descendants of immigrants and natives remains understudied. We examined inequalities in birthweight of mothers (G2) and daughters (G3) of foreign-born grandmothers (G1) compared with th

Background The shortage of surgeons, anaesthesiologists and obstetricians in low-income and middle-income countries (LMICs) is occasionally bridged by foreign surgical teams from high-income countries on short-term visits. To advise on ethical guidelines for such activities, the aim of this study was to present LMIC stakeholders' perceptions of visiting surgical teams from high-income countries. M

Introduction and objectives Children with attention deficit hyperactivity disorder (ADHD) have an increased risk of sleep problems. Weighted blankets are one possible non-pharmacological intervention for these problems in this group of children. However, the effectiveness of weighted blankets is insufficiently investigated. This study aims to investigate the effectiveness of weighted blankets in t

Objective: To report methodology and first-year results of a new educational project called Televascular Games,” which took place during coronavirus disease 2019 pandemic. Methods: Complex aneurysmal aortic disease was discussed during a 2-hour competition webinar, according to three modalities. (1) Planning case competition (PCC): Two to four preoperative computed tomography angiography (CTA) sca

Introduction It is standard of care to provide sedation to critically ill patients to reduce anxiety, discomfort and promote tolerance of mechanical ventilation. Given that sedatives can have differing effects based on a variety of patient and pharmacological characteristics, treatment approaches are largely based on targeting the level of sedation. The benefits of differing levels of sedation mus

The chapter examines the role of indirect review of administrative action in Swedish law. A general description of the overall structure of the Swedish system for judicial review of administrative action is followed by a discussion about the administrative measures that cannot be reviewed in a direct review.

This paper reports on the results of thermal response tests conducted with laboratory-grade instrumentation and equipmentfor a borehole system consisting of nine groundwater-filled boreholes, each about 80 m (262 ft) deep. The ground thermalproperties, including the undisturbed ground temperature, the thermal conductivity and the borehole thermal resistance, aredetermined for each of the nine bore

Lapptestning med palladium och aluminium (Swedish popular science summary)Lapptestning är standardmetoden för påvisning av kontaktallergi. Metoden har använts i över 100 år och utvecklas fortfarande. På 80-talet började flera kliniker i USA och Europa, inklusive Yrkes-och miljödermatologisk avdelning i Malmö, att lapptesta med palladiumklorid for att kunna påvisa palladiumallergi. Palladium är en AbstractThe aim of this thesis was to investigate the prevalence and significance of contact allergy to palladium from a Swedish perspective. Our initial findings made it necessary to also explore the importance of the metal aluminium used in test chamber systems and the effect of aluminium chloride (Al-Cl) in patch test preparations. A retrospective study (study I), with 18,306 patch test results

Post-flame sulfation of gaseous sodium hydroxide (NaOH) and sodium chloride (NaCl) was investigated with optical in situ measurements at 850 to 1475 °C. A multi-jet burner was used to generate well-controlled combustion environments. The multi-jet burner also enabled the separate feeding of the sodium species and SO2 to the combustion environment where the sulfation reactions occurred. Concentrati

Turbulent premixed flames subjected to extreme levels of turbulence exhibit reaction zone broadening and thinning. Instantaneous flame structures visualized using advanced laser diagnostic methods have shown significantly different behaviours of flame/turbulence interaction in jet flames stabilized on burners of different sizes. This paper aims to reconcile the controversy about flame broadening o

In this work, the fluorescence of FLEET (femtosecond laser electron excited tagging) was enhanced by two color femtosecond laser. the intensity of FLEET was increased about 20% with two laser pulses that were 400 μJ/pulse at 266 nm and 3 mJ/pulse at 800 nm, and the results indicated that there was nearly no influence on lifetime and wavelength of fluorescence from FLEET. This result provides many

Recent studies suggest that concrete creep may be further exacerbated by climate change. However, up to now this effect has not been quantified in literature. The current study addresses this gap and presents a probabilistic approach for quantitatively assessing this effect. For this purpose, five different stochastic creep models (i.e. Model Code 1999, Model Code 2010, B3, B4, and B4s models) are
