To develop anion exchange membranes (AEMs) that combine high chemical stability and hydroxide conductivity, we have designed and prepared poly(arylene piperidine)s carrying tunable mono- or dicationic side chains. Poly(biphenyl piperidine) and poly(biphenyl N-methylpiperidine), respectively, were first synthesized by superacid-catalyzed polyhydroxylalkylations. Subsequently, the piperidine rings o
The study investigated the effects of forest residue extraction on tree growth and base cations concentrations in soil waterunder different climatic conditions in Sweden. For this purpose, the dynamic model ForSAFE was used to compare theeffects of whole-tree harvesting and stem harvesting on tree biomass and the soil solution over time at 6 different forestsites. The study confirmed the results f
Objectives: We aimed to conduct a systematic review and meta-analysis on the incidence and prevalence of SSc covering the entire literature. Methods: This study followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement of 2009. We conducted a systematic search in MEDLINE, Web of Science and Embase to identify articles reporting incide
Cisplatin is one of the most commonly used drugs for the treatment of various solid cancers. However, its efficacy is restricted by severe side effects, especially dose-limiting nephrotoxicity. New platinum-based compounds are designed to overcome this limitation. Previous investigations showed that the platinum(IV)–nitroxyl complex PN149 is highly cytotoxic in various tumor cell lines. In the pre
For the past 30 to 40 years, regulation of the environment has been governed by Environmental Protection Agencies worldwide. During this time we have learned that regulations have significant costs, not just benefits, and that analysis of the cost and benefit of proposed rules is an indispensable component of responsible regulation. Despite present-day recognition of the importance of cost benefit
North Hoy is an area containing a remarkable diversity of vegetation in a small area. A phytosociological account of the hill vegetation of North Hoy is presented, making use of an ordination method to clarify the inter‐relationships of the moorland vegetation types, as well as traditional methods. It has proved very interesting to compare the vegetation with the account of Scottish Highland veget
We investigate here populations of cataclysmic variables (CVs) in a set of 288 globular cluster (GC) models evolved with the MOCCA code. This is by far the largest sample of GC models ever analysed with respect to CVs. Contrary to what has been argued for a long time, we found that dynamical destruction of primordial CV progenitors is much stronger in GCs than dynamical formation of CVs, and that
Objective: Antimicrobial resistance is a growing worldwide problem and is considered to be one of the biggest threats to global health by the World Health Organization. Insights into the determinants of antibiotic prescribing may be gained by comparing the antibiotic usage patterns of Australia and Sweden. Design: Publicly available data on dispensed use of antibiotics in Australia and Sweden betw
Although there is extensive research indicating the vital role of functional emotion regulation (ER) in healthy psychological development, such research has neglected examination of adolescents. One potential reason for this neglect is the lack of valid ER instruments developed specifically for adolescents. Further, the available ER instruments for adolescents usually require elaborate forms of co
Levulinic acid (LA) is considered to be one of the promising organic bio-platform chemicals and intermediates for the synthesis of fuels, chemicals, and polymers. In the present study, heterogeneous catalytic dehydration of hexose sugars, fructose and glucose, using a strong cation exchange resin (hydrogen form) as an acid catalyst, was performed to produce LA in an aqueous medium. The effect of s
Mammalian dihydroorotate dehydrogenase, the fourth enzyme of pyrimidine de novo synthesis is an integral protein of the inner mitochondrial membrane that faces the intermembrane space and is functionally connected to the respiratory chain via ubiquinone. Here, we describe the first cloning and analyzing of the complete cDNA of mouse dihydroorotate dehydrogenase. Based on our recent functional expr
The novel coronavirus SARS-CoV-2 (COVID-19) has spread globally in a short period of time and quickly developed into a pandemic. In connection with its progress, entire cities and countries have been closed down, people are quarantined, and infrastructure and trade have been suspended. As this is a new virus, no vaccine or antiviral drugs are available, but instead non-medical measures such as soc
Characteristics of the built environment, including access to unhealthy food outlets, are hypothesized to contribute to type 2 diabetes mellitus (T2D). Swedish nationwide registry data on 4,718,583 adults aged 35-80 years living in 9,353 neighborhoods, each with at least 1 food outlet, were geocoded and linked to commercial registers (e.g., restaurants and grocery stores). Multilevel logistic regr
Although there have been significant advances in the research field of critical infrastructures and vital societal functions during the last decade, there still exist many challenges in implementing and carrying out studies in practice. One of these challenges is a feasible method for mapping, analysing and visualising the cascading consequences that arise for critical infrastructures and societal
Background: Studies on the incidence of Cushing’s disease (CD) are few and usually limited by a small number of patients. The aim of this study was to assess the annual incidence in a nationwide cohort of patients with presumed CD in Sweden. Methods: Patients registered with a diagnostic code for Cushing’s syndrome (CS) or CD, between 1987 and 2013 were identified in the Swedish National Patient R
Tuning light emission in bulk and quantum structures by strain constitutes a complementary method to engineer functional properties of semiconductors. Here, we demonstrate the tuning of light emission of GaAs nanowires and their quantum dots up to 115 meV by applying strain through an oxide envelope. We prove that the strain is highly anisotropic and clearly results in a component along the NW lon
Popular Abstract in Swedish Syftet med denna avhandling är att utforska fenomenet vetenskapligt kritiskt tänkande, när det gäller dess olika innebörder, villkor och utveckling. Kritiskt tänkande studeras genom att analysera olika filosofiska och pedagogiska texter, utifrån ett hermeneutiskt-fenomenologiskt perspektiv. Avhandlingen som är skriven på engelska erbjuder läsaren en inblick i hur min egThe purpose of this thesis is to explore the phenomenon of critical thinking in scholarship as regards its meanings, conditions, and development using a hermeneutic-phenomenological approach. This exploration takes its departure in ancient Greece, following a historical movement of the phenomenon up to present day perspectives on critical thinking, revealing a range of different meanings and condi
Introduction: Venous thromboembolism (VTE) and cardiovascular disease (CVD) share some risk factors such as smoking, obesity, and dietary habits. Poor self-rated health (SRH) has been shown to be a predictor of arterial CVD and mortality for both men and women. The association between SRH and VTE has only been investigated in one previous Swedish study with a cohort that just contained women. This
