An Fe(III)-NHC complex has been employed for the green light driven catalysis of base-promoted homolytic aromatic substitution (BHAS) reactions. Tributylamine was used as a sacrificial electron donor, together with potassium carbonate as base in dimethyl sulfoxide as solvent. In contrast to previously studied photocatalysts, the excited Fe(III)-NHC complex is not reducing the arylhalide substrates

Majorana modes can be engineered in arrays where quantum dots (QDs) are coupled via grounded superconductors, effectively realizing an artificial Kitaev chain. Minimal Kitaev chains, composed by two QDs, can host fully localized Majorana modes at discrete points in parameter space, known as Majorana sweet spots. Unlike grounded superconductors, where the superconducting phase is a conserved quantu

Background: Unhealthy lifestyle behaviours, including unhealthy alcohol consumption, physical inactivity, smoking, and nonadherence to dietary recommendations, are major contributors to non-communicable diseases and mortality. While adopting healthy behaviours can reduce these risks in middle-aged adults, research is limited. Therefore, the aim of this study was to assess the distribution of unhea

Recent findings suggest that cartilage mechanical function may be a biomarker for early osteoarthritis (OA) pathology. Thus, the development of methodologies for in-vivo applications has expanded. However, when creep tests are performed, inconsistency in applied stress and testing duration impede meaningful comparisons. Therefore, this study investigates the impact of creep duration on cartilage m

We review our studies to assess charge carrier dynamics inside a perovskite film and interfacial charge transfer dynamics for a perovskite layer sandwiched by an electron transporting layer (ETL) such as TiO2 compact or mesoporous layer and a hole transporting layer (HTL) such as spiro-OMeTAD. Both electron and hole injection occur faster than electron-hole recombination inside a perovskite film,

Comprehensive screening of the general population is the only approach capable of identifying the majority of cases with celiac disease. In 2023, the Italian Parliament enacted a law to implement nationwide screening for celiac disease and type 1 diabetes. However, critical decisions regarding the target population, optimal timing, and screening methods remain unresolved. Previous observational st

Background: Long term β-blocker therapy after myocardial infarction (MI) reduces mortality and recurrent MI but evidence for this treatment predates contemporary acute coronary care. β-blocker treatment is a key quality of care indicator in the Swedish national quality register for acute coronary care, Riks-HIA. Between 2011 and 2015 a declining number of MI-patients discharged with a β-blocker fr

Strenuous physical activity can negatively affect constitutive innate immune function (CIF), the always present first line of defence against pathogens. CIF is non-specific, and thus vital when encountering novel pathogens. A lowered CIF likely increases the risk of infection and disease. Migratory birds engage in truly extreme physical activity during their endurance flights, however, little is k

Introduction: Forced Oscillation Technique (FOT) is increasingly used to measure obstruction in the airways; however, the association between airway obstruction and the actual symptom burden in asthma is not known. Therefore, we aimed to investigate central and peripheral airway obstruction, measured by FOT, in association to symptoms and quality of life in asthma. Methods: 319 asthma patients wer

Objective: This study aimed to report changes in the annual incidence of invasive treatment, changes in invasive treatment modalities, and sex differences in patients treated for intermittent claudication (IC) due to infrainguinal lesions in Sweden between 2009 and 2022. Methods: Data were collected from the Swedish Vascular Registry (Swedvasc), including all registrations of invasive treatment fo

Detecting a single elementary charge has become an important task to achieve as applications within quantumtechnologies such as for qubit readout, nanothermodynamics or single shot photodetection rely on the locationof single electrons. The use of microwave resonators as the readout method for the charge sensitive single electrondevices, such as quantum dots, has been extensively used to achieve h

The current Kidney Disease Improving Global Outcomes (KDIGO) guidelines recommend the use of the bedside creatinine-based Chronic Kidney Disease in Children (CKiD) equation to estimate glomerular filtration rate (GFR) in children and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation in adults. However, this approach causes implausible changes in estimated GFR (eGFR) at the

Background Increased vitamin B6 catabolism related to inflammation, as measured by the PAr index (the ratio of 4-pyridoxic acid over the sum of pyridoxal and pyridoxal-5'-phosphate), has been positively associated with lung cancer risk in two prospective European studies. However, the extent to which this association translates to more diverse populations is not known. Materials and methods For th

Heterogeneity in patient populations is an important issue in health economic evaluations, as the cost-effectiveness of an intervention can vary between patient subgroups, and an intervention which is not cost-effective in the overall population may be cost-effective in particular subgroups. Identifying such subgroups is of interest in the allocation of healthcare resources. Our aim was to develop

Organizations need to make sure that their level of safety is acceptable. Therefore it is important to know which factors contribute to the level of safety and how to monitor and improve these factors. One method used today to evaluate the level of safety in organizations is safety culture measurements. In different contexts, different models of safety culture are used. Safety culture is often con

During the last years a couple of emergencies have affected the Swedish municipality Ljungby and its inhabitants and forced the municipality to initiate emergency responses. Some examples are a flooding that happened during the summer of 2004, the storm Gudrun that occurred in January 2005 and the storm Per that occurred in January 2007. These emergencies, as well as other incidents, are situation

Popular Abstract in Swedish Levande organismer, inklusive människor, har en 14C/12C-kvot som återspeglar miljön. När materialet dör slutar kroppen att fylla på 14C och kroppens 14C börjar sönderfalla till 14N. Detta gav upphov till den klassiska 14C-dateringsmetoden, vilken utvecklades av professor W.F. Libby, 1949 och gav honom Nobelpriset i kemi 1960. 14C-datering används huvudsakligen inom arkeThe testing of nuclear weapons in the atmosphere, in the middle of the 20'h century, resulted in a bomb-pulse excess of atmospheric 14C. A bomb-pulse dating method was thus developed. The latter is a method to determine the time of formation of formerly living modern (i.e. living after 1955) material , based on the 14C/ 12C ratio in it. The objective of this work was to evaluate the factors that c
