CT-based radiostereometric analysis (CT-RSA) is a method of measuring implant micromotion using low-dose CT scans. We evaluated the precision, accuracy, and observer reliability of CT-RSA for measuring femoral stem translation in THA in vitro. A cementless femoral stem was implanted in a synthetic femur mounted on a calibrated micrometer platform. Controlled translations were applied along each or
Most European Union (EU) residents live in areas where outdoor air pollution levels exceed the 2021 World Health Organization (WHO) air quality guidelines for fine particles and nitrogen dioxide. Outdoor air pollution is classified as carcinogenic to humans, and both outdoor and indoor air contain established human carcinogens, including diesel exhaust particulates, benzo(a)pyrene [B(A)P] and benz
A resolved optical image of a gamma-ray emitter would be of enormous scientific interest. For gamma-ray sources associated with interacting stars (colliding winds or novae), stellar intensity interferometry (SII), envisioned as a second observing mode at the Cherenkov Telescope Array Observatory (CTAO), could yield images of the systems in visible light. Recent radius measurements of massive stars
This is the Replicated Computational Results (RCR) Report for the article “Testing Abstractions for Cyber-Physical Control Systems.” The article empirically studies how substituting different components in Cyber-Physical Systems (CPSs) testing with simulators impacts the fault-exposition. This RCR report describes the artefacts used in the article, how to use the testing setups used in the article
BACKGROUND: Previous research has identified a need for relevant evidence-based clinical guidelines in primary care physiotherapy. However, an essential first step is to identify the most prevalent diagnoses among patients seeking physiotherapy. Thus, this study aims to (I) identify the most prevalent musculoskeletal diagnoses and, (II) describe physiotherapy utilization and patient characteristic
The evolutionary transition to eusociality in the solitary ancestors of social insects, like ants, termites, wasps and bees, may have been initiated by an environmental induction of group living. Plasticity in social behaviour in response to the environment can be found in facultatively social insects. However, it is currently unknown which environmental cues trigger the individual decision of an
Play is a quintessential human behaviour, underpinned by motor organisation and fundamental for learning and development. However, the motor patterns underlying play have not been computationally characterised in children with autism, despite known play pattern differences, including reduced social and pretend play. Recent evidence of fundamental neuromotor disruption in autism suggests neuromotorPlay is a quintessential human behaviour, underpinned by motor organisation and fundamental for learning and development.

Production of polyhydroxyalkanoates is an important field in the biorefinery as bio-alternative to conventional plastics. However, its commercialization is still limited by high production cost. In this study, a process with the potential to reduce the production cost of polyhydroxyalkanoates was proposed. Mixed cultures accumulated polyhydroxyalkanoates using volatile fatty acid-rich effluents fr
The chiral compound (R)-3-hydroxybutyrate (3HB) is naturally produced by many wild type organisms as the monomer for polyhydroxybutyrate (PHB). Both compounds are commercially valuable and co-polymeric polyhydroxyalkanoates have been used e.g., in medical applications for skin grafting and as components in pharmaceuticals. In this paper we investigate cultivation strategies for production of 3HB i
Wastewater-based epidemiology (WBE) can be used to track the spread of SARS-CoV-2 in a population. This study presents the learning outcomes from over two-year long monitoring of SARS-CoV-2 in Stockholm, Sweden. The three main wastewater treatment plants in Stockholm, with a total of six inlets, were monitored from April 2020 until June 2022 (in total 600 samples). This spans five major SARS-CoV-2
INTRODUCTION: Automated cerebrospinal fluid (CSF) biomarker assays have largely replaced manual immunoassays for measuring amyloid pathology in CSF. We refitted and validated the ABIDE model, predicting progression from mild cognitive impairment (MCI) to dementia, with CSF measurements from the automated Elecsys platform. METHODS: We included 2413 MCI participants (998 [41%] amyloid-positive) from
Global usage of pharmaceuticals has led to the proliferation of bacteria that are resistant to antimicrobial treatments, creating a substantial public health challenge. Here, we investigate the emergence of sulfonamide resistance genes in groundwater and surface water in Patna, a rapidly developing city in Bihar, India. We report the first quantification of three sulfonamide resistance genes (sulI
Background: In a recently discovered microorganism, Halomonas boliviensis, polyhydroxybutyrate production was extensive and in contrast to other PHB producers, contained a set of alleles for the enzymes of this pathway. Also the monomer, (R)-3-hydroxybutyrate (3HB), possesses features that are interesting for commercial production, in particular the synthesis of fine chemicals with chiral specific
Polyhydroxyalkanoates (PHAs), as bio-based plastics, promise a transition from petroleum products to green and sustainable alternatives. However, their commercial production is yet impeded by high production costs. In this study, we assessed synthetic culture in mono and co-culture modes for bacterial PHA production. It was demonstrated that volatile fatty acids (VFAs) derived from food waste and
Wastewater-based surveillance (WBS) allows the analysis of pathogens, chemicals or other biomarkers in wastewater to derive unbiased epidemiological information at population scale. After re-gaining attention during the SARS-CoV-2 pandemic, the field holds promise as a surveillance and early warning system by tracking emerging pathogens with pandemic potential. Expanding the current toolbox of ana
Human adenovirus (HAdV) type F41 has been identified as a possible cause of the non-A-to-E hepatitis outbreak. This study uses wastewater monitoring to track HAdV F40 and F41, supporting clinical investigations and providing insights into the pathogen's role in the outbreak. Given the limited clinical monitoring in Sweden of HAdV-F40/41, this approach also helps estimate the true infection burden
Background: Halomonas boliviensis is a halophilic microorganism that accumulates poly(3-hydroxybutyrate) (PHB) using different carbons sources when nitrogen is depleted from the culture medium. This work presents an improved production of PHB using an air-lift reactor (ALR) that was fed with a concentrated solution of a carbon source, and was supplemented with an adequate airflow rate. Results: Si
Shifting the concept of municipal wastewater treatment to recover resources is one of the key factors contributing to a sustainable society. A novel concept based on research is proposed to recover four main bio-based products from municipal wastewater while reaching the necessary regulatory standards. The main resource recovery units of the proposed system include upflow anaerobic sludge blanket
Background: Lignocellulosic waste is a desirable biomass for use in second generation biorefineries. Up to 40% of its sugar content consist of pentoses, which organisms either take up sequentially after glucose depletion, or not at all. A previously described Escherichia coli strain, PPA652ara, capable of simultaneous consumption of glucose, xylose and arabinose was in the present work utilized fo
This study investigated the efficiency of the treatment processes of wastewater treatment plants (WWTPs) to remove severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and pepper mild mottle virus (PMMoV) from the wastewater and sewage sludge, as well as the influence of the mode of operation on the quality of the treated wastewater. SARS-CoV-2 and PMMoV were detected and quantified at dif
