Pumpa hårt och parkera i skuggan. I Ringråd för längre ringliv ges anvisningar om hur man på bästa sätt tar hand om sin cykel. Broschyren publicerades 1942, mitt under brinnande världskrig. Det rådde brist på gummi och det som fanns måste användas till annat och viktigare saker än att ersätta slangar som slarviga cyklister fördärvat. I fokus för den här artikeln står cykelns och cyklandets betydel

Objectives: The enormous burden that cardiovascular diseases put on individuals and societies warrants reliable biomarkers of disease risk to optimize disease prevention. We studied longitudinal movement (LMov) in arterial walls using ultrasound of the common carotid artery (CCA). We believe that LMov could be a sensitive biomarker of cardiovascular health and in this study, we evaluate the intra-

Drug-induced cognitive impairment (DICI) is a well-established, yet under-recognised, complication of many types of pharmacological treatment. While there is a large body of scientific literature on DICI, most papers are about drug-induced dementia in the elderly and one specific drug class. However, DICI also comprises subclinical symptoms, domain-specific forms of cognitive impairment as well as

Volymen behandlar den nordafrikanska drottningen Sophinisba, maka till Syphax och Masinissa. Begick självmord liksom Dido och Cleopatra. Hennes öde har behandlats av bl a historikerna Livius och Appianos, och litterärt av Petrarca, Gian Giorgio Trissino, Georgios Chortatsis, Govert van der Eembd, Corneille, Calderón, Lohenstein och Gaudenzio Brunacci. Teoretiska modeller: Georg Brandes och Walter

This study bridges occupational health and innovation management by proposing psychosocial safety climate (PSC) as a key precondition for employee-driven innovation (EDI). EDI emphasises employees’ unique potential to generate and implement innovative ideas, with conducive working conditions, particularly those supporting psychological health, being crucial. Using a mixed-method explanatory design

Purpose: Hyperoxemia is common in patients resuscitated after out-of-hospital cardiac arrest (OHCA) admitted to the intensive care unit (ICU) and may increase the risk of mortality. However, the effect of hyperoxemia on functional outcome, specifically related to the timing of exposure to hyperoxemia, remains unclear. Methods: The secondary analysis of the Target Temperature Management 2 (TTM-2) r

Photonic solutions are potentially highly competitive for energy-efficient neuromorphic computing. However, a combination of specialized nanostructures is needed to implement all neuro-biological functionality. Here, we show that donor-acceptor Stenhouse adduct dyes integrated with III-V semiconductor nano-optoelectronics have combined excellent functionality for bio-inspired neural networks. The

This document is created within the research project Nordic Fire and Rescue Services in the Twenty First Century (FIRE21). In this project, the fire and rescue services are seen as both governed by, and dependent on, formal and informal networks. A fundamental assumption in the research project is that efficient emergency management is dependent on efficient problem-solving in these networks. As a

Dredging operations in ports, rivers, and waterways are essential for maintaining navigable depths, but they result in large volumes of dredged sediments (DS) that are often unsuitable for immediate reuse due to their high moisture content, low strength, and contamination. Stabilization and solidification (S/S) techniques are widely employed to improve the geotechnical properties of DS, making theDredging operations in ports, rivers, and waterways are essential for maintaining navigable depths, but they result in large volumes of dredged sediments (DS) that are often unsuitable for immediate reuse due to their high moisture content, low strength, and contamination.

"Man kan fråga sig varför de som otvivelaktigt har makt att påverka samhället lockas så pass av satiren. De har ju redan makten att påverka på andra sätt.” Det skriver medieforskaren Joanna Doona, författare till Det politiska skrattet: satir och medborgarskap, apropå debatten kring sverigedemokraten Richard Jomshofs spridande av muslimfientliga bilder.

Introduction: Streptococcus pyogenes (group A streptococcus; GAS) is a pathogen causing over half a million deaths annually worldwide. Human immune cells respond to GAS infection by activating the NLRP3 inflammasome leading to the release of pro-inflammatory cytokines that control infection. We investigated the role of C4b-binding protein (C4BP) and factor H (FH) in the inflammasome response to GA

This thesis investigates few-body quantum rings, particularly in the study of ultracold bosonic gases and nanowire quantum dots. These systems are investigated numerically using exact diagonalization methods. This dissertation contains five chapters which develop numerical and theoretical background for understanding the few-body calculations and analysis contained in the four included papers: Pap

Ambient pressure X-ray photoelectron spectroscopy is employed to study in real time the chemical reactions occurring on (Ag,Cu)(In,Ga)Se2 (ACIGSe) surfaces during the first atomic layer deposition (ALD) cycle of HfOx under realistic synthesis conditions by using tetrakisdimethylamido-hafnium (TDMA-Hf) and H2O precursors. We find that the initial deposition due to surface reactions of HfOx ALD on A

Large-class university lectures remain commonplace, yet their educational value is contested. While the majority of criticism contrasts transmissive lectures with active learning pedagogies, this case study evaluates a lecture series on its intrinsic qualities, looking at staff and student understandings of the lecture’s contribution to academic outcomes and the affect attendance has on students’

Fog makes a significant contribution to the hydrology of a wide range of important terrestrial ecosystems. The amount and frequency of fog immersion are affected by rapid ongoing anthropogenic changes but the impacts of these changes remain relatively poorly understood compared with changes in rainfall. Here, we present the design and performance of a novel experiment to actively manipulate low ly

Simultaneous rheological, polarized light imaging, and small-angle X-ray scattering experiments (Rheo-PLI-SAXS) are developed, thereby providing unprecedented level of insight into the multiscale orientation of hierarchical systems in simple shear. Notably, it is observed that mesoscale alignment in the flow direction does not develop simultaneously across nano-micro lengthscales in sheared suspen

Background: Two risk factors for severe retinopathy of prematurity (ROP) in extremely preterm infants are thrombocytopenia and low levels of arachidonic acid (AA) and docosahexaenoic acid (DHA). To date, these risk factors have not been linked. Method: Infants born < 28 weeks gestational age (GA) from 2016 to 2019 were randomized to postnatal enteral AA/DHA supplementation or standard care (contro
