The growing energy demand and the impact of polluting gases lead to the necessity of alternative energy sources and conversion energy devices. Fuel cells (FCs) appears as a suitable solution for facing the mentioned issues. Predicting the behavior of a polymer electrolyte fuel cell (PEFC) under different conditions represents a proper initial step to solve the several issues, e.g., aging water bal
Introduction The aim of this study was to describe the complications of ureteroscopy (URS) and to investigate whether performing URS outside normal working hours leads to increased risk for clinically significant complications. Material and methods A cohort of 486 consecutive patients treated with URS, with a total of 567 sessions between 2009 and 2015 at Helsingborg/Ängelholm Hospital, Sweden, wa
Background and purpose — Few prospective studies have reported the long-term effect durability of collagenase injections for Dupuytren disease. We assessed the 3-year treatment outcome of collagenase injections and predictors of recurrence. Patients and methods — We conducted a single-center prospective cohort study. Indication for collagenase injection was palpable Dupuytren’s cord and active ext
Disentangling the individual and interactive effects of multiple stressors on microbial communities is a key challenge to our understanding and management of ecosystems. Advances in molecular techniques allow studying microbial communities in situ and with high taxonomic resolution. However, the taxonomic level which provides the best trade-off between our ability to detect multiple-stressor effec
In Parkinson's disease, the degeneration of dopaminergic neurons in substantia nigra leads to a decrease in the physiological levels of dopamine in striatum. The existing dopaminergic therapies effectively alleviate the symptoms, albeit they do not revert the disease progression and result in significant adverse effects. Transplanting dopaminergic neurons derived from stem cells could restore dopa
Using Arctic sea ice concentration derived from passive microwave satellite observations in autumn and early winter over the 1979-2014 period, the Arctic region was objectively classified into several smaller regions based on the interannual sea ice variability through self-organizing map analyses. The trend in regional sea ice extent (RSIE) in each region was removed using an adaptive, nonlinear,
Background: Complex I (CI or NADH:ubiquinone oxidoreductase) deficiency is the most frequent cause of mitochondrial respiratory chain defect. Successful attempts to rescue CI function by introducing an exogenous NADH dehydrogenase, such as the NDI1 from Saccharomyces cerevisiae (ScNDI1), have been reported although with drawbacks related to competition with CI. In contrast to ScNDI1, which is perm
Background: In collaboration with United European Gastroenterology, the working group on ‘Harmonizing diagnosis and treatment of chronic pancreatitis across Europe’ (HaPanEU) developed European guidelines for the management of chronic pancreatitis using an evidence-based approach. Methods: Recommendations of multidisciplinary review groups based on systematic literature reviews to answer predefine
Filamentous fungi play a key role as decomposers in Earth’s nutrient cycles. In soils, substrates are heterogeneously distributed in microenvironments. Hence, individual hyphae of a mycelium may experience very different environmental conditions simultaneously. In the current work, we investigated how fungi cope with local environmental variations at single-cell level. We developed a method based
In order to combat the effects of climate change, it is important to use a combination of solutions to achieve carbon neutrality as soon as possible. Carbon capture and sequestration is one such technology that can be used to significantly reduce the carbon footprint of many industrial plants. A mature technology for CO2 capture, amine-based post-combustion capture, is readily available today. How
In the next 24 years, the Malawian population is expected to double, a development that will inevitably affect access to land and land holding sizes. As access to land is already limited, securing food for the growing population will require policy shifts including the promotion of agricultural intensification. Malawi’s economy depends on the agricultural sector, and this paper addresses the gener
Copper from vehicles disc brakes is one main contributor of the total copper found in the environment. Therefore, the U.S. Environmental Protection Agency (EPA) and the automotive industries started the Copper-Free Brake Initiative. The pad friction material is essentially composed of a binder, fillers, reinforcing fibres and frictional additives. Copper and brass fibres are the most commonly used
Objective: To describe the development and evaluation of the content and face validity and test-retest reliability of a disease-specific questionnaire that measures patient-reported outcomes and experiences for the Swedish National Diabetes Register for adult patients who have type 1 or type 2 diabetes. Methods: In this methodological study, a questionnaire was developed over four phases using an
This paper presents two case studies of Swedish ICT 'gap exploiter' companies to provide a nuanced perspective in the investigation of ICT reuse business models and policies. Gap exploiters are third-party firms that create value through the re-utilization of existing products. While extending product life through the gap exploiter model is promising in the transition to a circular economy, busine
The likelihood that females will breed or how much they invest in reproduction can depend on the characters of their male partners. Such differential allocation may enhance or limit gene flow between hybridizing lineages, in particular when the lineages have diverged in sexually selected characters. Populations of the common wall lizard (Podarcis muralis) in some regions of Italy exhibit striking
The measurement of azimuthal correlations of charged particles is presented for Pb-Pb collisions at sNN=2.76 TeV and p-Pb collisions at sNN=5.02 TeV with the ALICE detector at the CERN Large Hadron Collider. These correlations are measured for the second, third and fourth order flow vector in the pseudorapidity region |η| < 0.8 as a function of centrality and transverse momentum pT using two obser
