The production of fast pyrolysis bio-oil (FPBO) from secondary biomass is a promising technique for the production of liquid biofuels. However, the resulting FPBO is often viscous and chemically unstable, requiring significant upgrading while also being difficult to work with. To overcome this issue, FPBO can be hydrotreated using slurry hydrotreatment, which has a long history as a processing tec

Streptococcus pneumoniae resists host defenses through multiple surface factors, yet their specific contribution to protection against antimicrobial peptides remains incompletely understood. We examined the role of pneumococcal surface protein A (PspA) and the polysaccharide capsule in protection against the human defensin HNP-1. PspA conferred increased resistance to HNP-1-induced killing, shown

A key challenge in developing sustainable cities is establishing circular infrastructure systems. Decentralised urban water management solutions (DUWMS) are a case in point: Innovative DUWMS that allow recycling the water, heat, energy, or nutrients contained in wastewater locally are currently emerging in cities around the world. These systems could significantly enhance cities’ water resilience

Staphylococcus aureus remains one of the most elusive targets in bacterial vaccinology, primarily due to its complex immune evasion strategies and the phenomenon of immune imprinting. Despite decades of research and numerous clinical trials, no vaccine has demonstrated protective efficacy in humans. This review examines the underlying reasons for these failures and proposes a rational, integrativ

Antibiotic persistence arises when a subset of cells in an otherwise susceptible bacterial population temporarily exhibits elevated tolerance to bactericidal antibiotics. While significant progress has been made in elucidating persister mechanisms, much of this research has focused on Gram-negative bacteria, and these findings are not always applicable to Gram-positive species. This study explores

The twin transition, which combines green and digital innovation in economic activities, is increasingly central to policy agendas and is also receiving growing attention in regional research. However, accurately mapping green, digital and twin (both green and digital) economic activities across regions remains challenging, particularly due to data constraints. In this study, we advance this resea

A simple Pickering emulsion route has been developed for the assembly of temperature-responsive poly(N-isopropylacrylamide) (PNIPAM) microgel particles into colloidal molecules comprising a small number of discrete microgel interaction sites on a central oil emulsion droplet. Here, the surface activity of the microgels serves to drive their assembly through adsorption to growing polydimethylsiloxa

Research SummaryGrowth often requires start‐ups to recruit new skills not present in the founding team. We analyze if the relationship between integrating new skills and growth depends on timing. Should new skills be recruited as early as possible, or can start‐ups add them as needed along the way? Using a unique panel dataset covering Sweden's population of start‐ups from 1997 to 2012, our analys

Hybrid anisotropic microgels were synthesised using mesoporous silica as core particles. By finely controlling the synthesis conditions, the latter can be obtained with different shapes such as platelets, primary particles or rods. Using the core particles as seeds for precipitation polymerisation, a crosslinked poly(N-isopropylacrylamide) (PNIPAM) microgel shell could be grown at the surface, con

Introduction Children with appendicitis often present with complicated disease. The aim of this study was to describe the clinical management of pediatric appendicitis, and to report how disease severity and operative modality are associated with short- and long-term risks of adverse outcome. Materials and Methods A nationwide retrospective cohort study of all Swedish children (<18 years) diagnose

In this article, we demonstrate a method for inducing reversible crystal-to-crystal transitions in binary mixtures of soft colloidal particles. Through a controlled decrease of salinity and increasingly dominating electrostatic interactions, a single sample is shown to reversibly organize into entropic crystals, electrostatic attraction-dominated crystals, or aggregated gels, which we quantify usi

Critical infrastructures provide services that are essential for the functioning of our society and extensive disruptions in these can have widespread effects. These effects are not only limited to the directly affected infrastructure but also indirectly through interdependencies to other infrastructures. By only account-ing for the direct consequences when analysing critical infrastructures, the

AIM: Preterm birth is associated with a number of physical and mental health issues. The aim of this study was to find out if there was also any association between individuals born preterm in Sweden between 1984 and 2006 and the risk of unintentional injuries during childhood, adolescence and young adulthood METHODS: The study followed 2,297,134 individuals, including 5.9% born preterm, from 1985

Background Individual-based cognitive-behavioural therapy (CBT) is in short supply and expensive. Aims The aim of this randomised controlled trial (RCT) was to compare mindfulness-based group therapy with treatment as usual (primarily individual-based CBT) in primary care patients with depressive, anxiety or stress and adjustment disorders. Method This 8-week RCT (ClinicalTrials.gov ID: NCT0147637

Background: Respiratory tract deposition of air pollution particles is a key to their adverse health effects. This study was aimed to determine the size-resolved deposition fraction (DF) of sooty wood smoke particles in the lungs of healthy subjects. The type of wood smoke investigated is typical for household air pollution from solid fuels, which is among the largest environmental health problems

Background: Anxiety has been suggested to increase among young individuals, but previous studies on longitudinal trends are inconclusive. The aim of this study was to analyze longitudinally, the changes over time of prevalence of self-reported anxiety in the Swedish population between 1980/1981 and 2004/2005, in different birth cohorts and age groups. Methods: A random sample of non-institutionali

Critical infrastructures must be both robust and resilient in order to ensure the functioning of society. A key activity in ensuring their proper function is finding and addressing system weaknesses by the means of risk and vulnerability analysis. A critical factor of such analysis is the ability to determine the negative consequences of various types of contingencies. Numerous mathematical and si

Lipid membranes are highly mobile systems with hierarchical, time and length scale dependent, collective motions including thickness fluctuations, undulations, and topological membrane changes, which play an important role in membrane interactions. In this work we have characterised the effect of encapsulating two industrially important enzymes, β-galactosidase and aspartic protease, in lipid spon
