Previous theoretical work on range expansions over heterogeneous environments showed that there is a critical environmental gradient where range expansion stops. For populations with freely recombining loci underlying the trait under selection (hereafter, “adaptive loci”), the critical gradient in one-dimensional habitats depends on the fitness cost of dispersal and the strength of selection relat

Background: Predicting a challenging clot when performing mechanical thrombectomy in acute stroke can be difficult. One reason for this difficulty is a lack of agreement on how to precisely define these clots. We explored the opinions of stroke thrombectomy and clot research experts regarding challenging clots, defined as difficult to recanalize clots by endovascular approaches, and clot/patient f

Objective People with neuropsychiatric symptoms often experience delay in accurate diagnosis. Although cerebrospinal fluid neurofilament light (CSF NfL) shows promise in distinguishing neurodegenerative disorders (ND) from psychiatric disorders (PSY), its accuracy in a diagnostically challenging cohort longitudinally is unknown. Methods We collected longitudinal diagnostic information (mean=36 mon

Bioelectronics can potentially complement classical therapies in nonchronic treatments, such as immunotherapy and cancer. In addition to functionality, minimally invasive implantation methods and bioresorbable materials are central to nonchronic treatments. The latter avoids the need for surgical removal after disease relief. Self-organizing substrate-free organic electrodes meet these criteria an

Purpose Hodgkin lymphoma (HL) survivors are at an increased risk of stroke because of carotid artery irradiation. However, for early-stage HL involved node radiation therapy (INRT) reduces the volume of normal tissue exposed to high doses. Here, we evaluate 3-dimensional conformal radiation therapy (3D-CRT), volumetric-modulated arc therapy (VMAT), and proton therapy (PT) delivered as INRT along w

PURPOSE: To investigate acute and long-term changes in hormonal and inflammatory biomarkers in nonambulant children with cerebral palsy in response to dynamic standing exercise.METHODS: Fourteen children with severe cerebral palsy were recruited. Anthropometrics and body composition measures were obtained. Physical activity levels before the study were assessed using hip-worn accelerometry. All ch

The number of Life Cycle Assessment (LCA) studies on foods and diets steadily increases. However, due to lack of data on food products as well as time and resource constraints, many of these studies ignore part of the system (e.g. cooking and waste in the household), which may lead to underestimating impacts greatly. This LCA study compared diets using six methods with different system boundaries;

Insulin resistance causes compensatory insulin production, which in humans can eventually progress to β-cell failure and type 2 diabetes (T2D). This disease progression involves multi-scale processes, ranging from intracellular signaling to organ and whole-body level regulations, on timescales from minutes to years. T2D progression is commonly studied using overfed and genetically modified rodents

An enhanced flamelet generated manifold (FGM) model for large eddy simulation (LES) of turbulent spray combustion is presented. In the enhanced FGM model, a transported probability density function (TPDF) description of the FGM variables is employed. The TPDF is represented using the Eulerian stochastic fields (ESF) approach, and the method is applied to LES of spray combustion under conditions re

Background and purpose - Hip surveillance in children with cerebral palsy (CP) includes repeated radiographic hip examinations and measurements of the hip migration percentage (MP) to identify hips in need of surgery early, to prevent dislocation with the fewest number of radiographic examinations possible. We analyzed the early development of the MP in hips operated on to prevent hip dislocation

Introduction: Social media provides nurses with tools to share information, debate healthcare policy and practice issues, and engage in interpersonal interactions. Historically, also in Scandinavia, nurses’ trade unions have taken the lead in defining nursing as a profession and supporting nurses in ‘conducting good nursing’. However, it is unexplored how trade unions guide nurses in social media

AIM: To compare two identification methods for risky drinking in primary health care centres (PHCs).METHODS: Sixteen PHCs from three Swedish counties were randomized into strands: consultation-based early identification (CEI) or systematic screening early identification (SS). Measurements took place at baseline and during two intervention periods. Patients filled in questionnaires including gender

The association between higher education and political attitudes is well-recognized, and research suggests that socialization amongst peers is one of the most probable mechanisms explaining a possible attitudinal change. However, identifying a socialization effect is difficult due to self-selection mechanisms and limitations in data availability. This article empirically investigates the underlyin

Tänk dig tillbaka till 1900 talets början, till en produktionsanläggning för lut och syntetiskt färgmedel. Varje andetag svider i lungorna från den starkt förorenade luften och när du efter dit arbetspass på 12 timmar kommer, hem så känner du fortfarande den skarpa doften. Så var verkligheten för fabriksanställda och så gott som alla i den urbana miljön på den tiden. Hur kommer det sig att vi idagFORMOX™ is a formaldehyde production process, utilizing a metal oxide catalysts. The new generation of plants is pressurized, therefore the turbo charger concept has been developed. This concept deploys a turbine coupled to a compressor, where the turbine recovers a substantial part of the electric power needed to run the compressor, from the outlet of the emission control system unit (ECS) in the

The purpose of this Essay is to study whether Swedish Army Officers of today are less prepared for an armed conflict than their older colleagues. The study is a text analysis of Meir Finkel’s theory on Cognitive and Command Flexibility, Swedish military Doctrines and other relevant documents. A research report put together by Swedish Defence Research Agency examining the process of career developm

In this master’s thesis, a novel unsupervised anomaly detection tool was developed in collaboration with Sandvik Rock Processing to assist engineers and experts in analyzing large amounts of sensor data from cone crushers used in the stone crushing industry. The tool focuses on analyzing power, pressure, and CSS sensor data. A crucial preprocessing step was implemented to algorithmically identify

Uppsatsen undersöker huvudsakligen gällande rätt beträffande tillåtligheten av skriftliga vittnesattester i svenska kommersiella skiljeförfaranden. Undersökningen är inriktad på förutsättningarna för skiljenämnden att tillåta, påbjuda eller förbjuda användandet av skriftliga vittnesattester när en av parterna bestrider att de ska användas. Undersökningens syfte är således att genom den rättsdogmatThe paper mainly examines the legal situation regarding the admissibility of written witness statements in Swedish commercial arbitration. The study focuses on the prerequisites for the arbitral tribunal to permit, require or prohibit the use of written witness statements when one of the parties objects their use. The purpose of the paper is to thus to determine, de lege lata, the extent of the ar

This study explored how midwives and healthcare counselors in Sweden support women experiencing fear of childbirth, with a focus on how they balance patients' preferences with medical guidelines and their influence in determining the mode of delivery. The method chosen was qualitative, semi-structured interviews with midwives and healthcare counselors from specialized maternity support teams w
