In order to elucidate the multidimensional response mechanism for migration of antibiotics and spread of resistome in riverbed driven by river water level fluctuations, dynamic reactors were set up to simulate the variation of sulfamethazine vertical migration, biotransformation and resistance genes expression according to fluctuation direction and magnitude. The upward fluctuation of water level

Black carbon (BC) is produced by incomplete combustion of biomass and fossil fuels and is released as aerosols to the atmosphere with effects on the climate, environment, and human health. Current BC emissions are well monitored in many parts of the world. However, the geographical coverage is limited, and historical records of BC accumulation are still scarce. Here we present a quantification of

This work presents an alternative cetane rating method using a production compression ignition (CI) engine, offering an accessible approach for preliminary fuel evaluation without the need for specialized equipment. As part of this work, an empirical correlation was developed linking ignition delay (ID) to both the cetane number (CN) and intake oxygen concentration. The test method follows the pri

BackgroundThe captive bolt gun is a tool for stunning animals in the meat industry and is not considered a firearm under the Swedish firearm legislation. This study aimed to explore the involvement of such devices in human fatalities, with an emphasis on suicides. Epidemiological characteristics from a longitudinal perspective, as well as risk factors and injury patterns were analyzed.MethodSuicid

Background: Prolonged time to surgery (TTS) after neoadjuvant chemoradiotherapy (nCRT) may enable malnourished oesophageal cancer patients' nutritional status to recover better, possibly improving outcomes with fewer complications and better overall survival (OS) after oesophagectomy. Methods: This is a substudy within a multicentre randomised controlled trial comparing outcomes in patients with o

BackgroundBreathlessness is a common and distressing symptom across a wide range of medical conditions. Different aspects (dimensions) of breathlessness can be assessed using the Multidimensional Dyspnoea Profile (MDP) and Dyspnoea-12 (D12) questionnaires. We aimed to examine whether the order of completing MDP and D12 affects the breathlessness responses in people with cardiorespiratory disease.M

The efficiency and stability of wide bandgap (WBG) perovskite solar cells (PSCs) are constrained by photo-induced halide segregation and severe non-radiative recombination, which significantly impedes the advancement of high-efficiency and stable perovskite/silicon tandem solar cells (PSTSCs). In this work, a potassium 4-sulfonic-1,8-naphthalic anhydride salt (4S-NAPS), featuring dual-anchoring si

Purpose: This study aimed to evaluate the ability of a thigh-worn accelerometer to detect walking during daily life in individuals with Lumbar Spinal Stenosis (LSS). Two hypotheses were made regarding how walking measurements from the accelerometer, a walking test, and an ankle-worn StepWatch would relate in order for the accelerometer to be valid. The hypotheses were: (a) there is no difference b

Biomass gasification gas (BGG), a carbon-neutral renewable fuel and important hydrogen carrier, holds significant promise for sustainable energy systems. However, its practical implementation is challenged by combustion instability and elevated NOx emissions, primarily due to localized high-temperature zones induced by the hydrogen content. MILD (Moderate or Intense Low-oxygen Dilution) combustion

The design of iron complexes with long-lived charge transfer states suitable for applications as photosensitizers remains a formidable challenge. Here, we investigated the effect of an extended ligand π-system on the ground- and excited-state properties of iron(II) complexes with N-heterocyclic carbene (NHC) ligands. For this purpose, three iron complexes based on the established [Fe(II)(pbmi)2]2+

Objectives Early detection of neurosensory injury among workers exposed to hand-arm vibration is crucial. The aim of our study was to evaluate the diagnostic test performance of clinical point-of-care testing using a tuning fork and temperature rollers in relation to vibrotactile and thermal quantitative sensory testing. Methods We recruited 225 vibration-exposed workers who underwent clinical poi

To facilitate high-throughput biomarker discovery and high-density protein-chip array analyses of complex biological samples, a novel macro- and nanoporous silicon surface for protein microarrays was developed. The surface offers three-dimensional surface enlarging properties and spot confinement, enabling both high sensitivity bioassays and design of high density arrays. Reproducible manufacturin

Objective. Infected pancreatic necrosis is the main cause of death in patients with acute pancreatitis, and therefore its early prediction is of utmost importance. Endogenous cortisol metabolism plays a basic role both in the course of acute pancreatitis and in the process of infection. The purpose of this study was to analyze corticosteroid-binding globulin (CBG), total cortisol, calculated free

Aims: Several studies have shown that self-rated health (SRH ) is associated with drug use. The aim of this study was to investigate the possible interaction between SRH and use of analgesics and hypnotics and its ability to predict disability pension. Methods: In 1974-78, complete birth-year cohorts of middle-aged male residents in Malmö, Sweden, were invited to a health screening, and the cohort

In all works on medieval Iceland, we meet the same narrative of the conversion of Iceland to Christianity, which is supposed to have taken place in the year 999 or 1000 AD. But how does this narrative stand the trial of source criticism? Radical source criticism was introduced in Nordic historiography when Lauritz Weibull published his Critical Studies in Nordic History Around the Year 1000 in 191

Background: The thorough assessment of familial prostate cancer (PCa) risk is as important as ever to provide a basis for clinical counselling and screening recommendations. Objective: Our aim was to determine the age-specific risks of PCa and the risk of death from PCa according to the number and the age of affected first-degree relatives. Design, setting, and participants: The nationwide Swedish

Objective To determine whether environmental control using nocturnal temperature controlled laminar airflow (TLA) treatment could improve the quality of life of patients with persistent atopic asthma. Design Randomised, double-blind, placebo-controlled, parallel-group trial. Setting Nineteen European asthma clinics. Participants 312 patients aged 7-70 with inadequately controlled persistent atopic
