Dimethyl ether (DME) is promising as an additive for co-firing with ammonia (NH3) to solve the problem of its low reactivity combustion. However, the combustion modeling of blended fuels is challenging, and previous efforts primarily relied on the adjustment of rate constants for key reactions to bridge the gap between experiments and simulations. In the present work, ab initio kinetic studies wer
This chapter is concerned with Turkish heritage speakers (HSs) in Germany, here exemplified by 21 early bilinguals during adulthood who live in Hamburg, North Germany. We introduce the population, report their self-perceived proficiency and propose the Turkish Use Score (TUS) that is based on quantitative aspects of language use (e.g., the number of people Turkish is spoken with) and qualitative o
Design thinking is an innovative methodology that may be applied by small and medium enterprises which emphasizes a human-centered approach to problem-solving, facilitating the creation of novel solutions for complex and open-ended challenges like the development of new products. Despite its recognized importance in business and academia, many industrial SMEs struggle with applying design thinking
This study explores how traffic safety implementation at local level in line with the 2030 Agenda for Sustainable Development is characterised. By investigating interactions between traffic safety and other sustainability goals (synergies), as well as identifying contradictions between goals and conflicting interests (challenges), the study aims to pinpoint the main enablers for implementing traff
Background: The TrialNet Oral Insulin (OI) prevention trial showed no overall treatment effect, using the diagnosis of type 1 diabetes as an endpoint. A significant delay in onset was only found in a high-risk stratum (termed secondary stratum 1) of participants with low first-phase insulin release (FPIR).Methods: Since trials with an endpoint of type 1 diabetes take years to complete, in this pos
The idea that tunneling is enhanced by the compression of the donor-acceptor distance has attracted significant interest. In particular, recent studies argued that this proposal is consistent with pressure effects on enzymatic reactions, and that the observed pressure effects support the idea of vibrationally enhanced catalysis. However, a careful analysis of the current works reveals serious inco
III-Nitride based LEDs based on InGaN active layers on GaN work very well for the blue and green emitting LEDs. However, the large lattice mis-match between redemitting active layers, with at least 35% indium in the active layers, and the GaN substrate still limits the efficiencies obtained to very low values. Unfortunately, the approach to use GaAs based (GaAs/AlInGaP) devices for the red fails f
This study investigates the relationship between passenger volumes and the frequency and size of dwell times for commuter trains. We use data collected by automatic passenger count systems in Stockholm and show that dwell times often take longer than scheduled. To understand the effect of passenger volumes on delays, we use the frequencies of delays for different passenger volumes and delay sizes.
Introduction: While timely assessment of long-term survival for patients with liver cancer is essential for the evaluation of early detection and screening programs of liver cancer, those data are extremely scarce in China. We aimed to timely and accurately assess long-term survival for liver cancer patients in eastern China.Methods: Patients diagnosed with liver cancer during 2004-2018 from four
On February 23, 2022, The EU Commission published its Proposal for a Directive of the European Parliament and of the Council on Corporate Sustainability Due Diligence and amending Directive (EU) 2019/1937 (“CSDDD” or “the Proposal”). The purpose of the Proposal, to further the “Union’s transition to a climate-neutral and green economy in line with the European Green Deal and in delivering on the U
Modelling has been a mainstay of conventional planning support tools (PSTs) since the 1960s and is instrumental in transport and land use planning decision-making. Numerous studies have been conducted to model the potential impacts of emerging vehicle automation and sharing technologies. A systematic review of recent modelling studies of autonomous and shared vehicles in the research literature ex
Multigene assays for molecular subtypes and biomarkers can aid management of early invasive breast cancer. Using RNA-sequencing we aimed to develop single-sample predictor (SSP) models for clinical markers, subtypes, and risk of recurrence (ROR). A cohort of 7743 patients was divided into training and test set. We trained SSPs for subtypes and ROR assigned by nearest-centroid (NC) methods and SSPs
The aim of the present study is twofold: to explore the assessment andintervention practices of Swedish practitioners (mainly Speech and LanguageTherapists: SLTs) for multilingual children with Developmental LanguageDisorders (DLD) and to explore to which extent they perceive themselves asconfident with respect to assessment and intervention. The data comes fromthe Swedish part of the survey by th
Background: In Sierra Leone persons with disabilities are at higher risk of living in poverty and have poor access to a fragile healthcare and rehabilitation services. The aim was to explore stakeholders’ perceptions of access to health and rehabilitation services for persons with disabilities in Sierra Leone. Methods: Seven focus group discussions, including stakeholders working within the field
BACKGROUND/OBJECTIVES: Increased level of glycated hemoglobin (HbA1c) is associated with type 1 diabetes onset that in turn is preceded by one to several autoantibodies against the pancreatic islet beta cell autoantigens; insulin (IA), glutamic acid decarboxylase (GAD), islet antigen-2 (IA-2) and zinc transporter 8 (ZnT8). The risk for type 1 diabetes diagnosis increases by autoantibody number. Bi
Background: Systemic sclerosis (SSc) can lead to visible changes in appearance which could generate concerns among patients. Thus, valid questionnaires that capture these concerns are valuable to identify and communicate appearance concerns. Objective: To determine aspects of the validity and reliability of the Swedish version of the Satisfaction with Appearance scale for individuals with SSc (SWA
For internal cooling of a turbine blade, various advanced rib turbulators can markedly contribute to the heat transfer enhancement while suffering a great increase in pressure loss. In those designs, ribs with the same configuration are periodically and evenly mounted on the channel wall. In this context, this work proposes a hierarchical design concept to optimize the rib arrangement with the des
