Ammonia (NH3) is an inorganic substance considered as a promising fuel for power sector decarbonization. As a result of the absence of carbon in its structure, ammonia is capable of producing energy with zero CO2 emissions when burned. However, the combustion of NH3 presents several challenges as a result of its low reactivity and low flame speed as well as the formation of large quantities of nit
The coronavirus disease 2019 (COVID-19) pandemic led to an abrupt halt of many Alzheimer's disease (AD) research studies at sites spanning the world. This is especially true for studies requiring in-person contact, such as studies collecting biofluids. Since COVID-19 is likely to remain a threat for an extended period, the resumption of fluid biomarker studies requires the development and implemen
Identification of biomarkers associated with protection from developing diabetic complications is a prerequisite for an effective prevention and treatment. The aim of the present study was to identify clinical and plasma metabolite markers associated with freedom from vascular complications in people with very long duration of type 1 diabetes (T1D). Individuals with T1D, who despite having longer

Operating lignocellulosic fermentation processes to produce fuels and chemicals is challenging due to the inherent complexity and variability of the fermentation media. Real-time monitoring is necessary to compensate for these challenges, but the traditional process monitoring methods fail to deliver actionable information that can be used to implement advanced control strategies. In this study, a
Two-dimensional laser-induced incandescence (LII) measurements usually involve the use of a cylindrical lens to illuminate the planar region of interest. This creates a varying laser fluence and sheet width in the imaged flame region which could lead to large uncertainties in the quantification of the 2D LII signals into soot volume fraction distributions. To investigate these effects, 2D LII meas
Ungulate prey can use increased vigilance to reduce their risk of predation, but little is known of the combined and interactive risk effects from humans and wolves in determining ungulate behaviour across time and space. Understanding the interplay between these risk effects is increasingly important, considering the recolonisation of several large carnivores to more human-dominated landscapes in
Since its inception in 1980, the International Christian Embassy Jerusalem (ICEJ) has developed into a central player in the formation of Christian Zionism globally. It is known through its high profile in Israeli society, its financial, moral and political support for the State of Israel and its controversial mix of theology and politics. This article focuses on ICEJ's ideological and theological
To increase the reliability and comparability of vocal loading studies, this paper proposes the use of a standardized approach with experiments that are [1] grounded on consistent definitions of terms related to vocal fatigue (vocal effort, vocal demand, and vocal demand response), and [2] designed to reduce uncertainty and increase repeatability. In the approach, a semi-automated vocal loading ta
Analogical transfer, denoting the ability to use an action that solved a given problem in order to successfully handle a seemingly different but functionally similar problem, requires well- developed self-regulation, as it draws on previous knowledge and demands selecting and shift- ing between relevant features while ignoring irrelevant ones. Thus, analogical transfer involves executive functions
Objective: The clinical significance of QT interval adaptation to heart rate changes has been poorly investigated in atrial fibrillation (AF), since QT delineation in the presence of f-waves is challenging. Therefore, the objective of the present study is to investigate new techniques for QT adaptation estimation in permanent AF. Methods: A multilead strategy based on generalized periodic componen
This paper investigates the role of human agency in 40 phases of regional economic development in 12 Nordic regions over 30 years. It contributes with a theoretical framework to study agency over time and a fuzzy-set qualitative comparative analysis based on a unique dataset combining over 200 interviews, with printed and online sources, and quantitative data. The paper identifies which combinatio
A large share of health-related information is today sought and communicated via the internet, including in social media. Questions have been raised about how this may affect health perceptions and behaviors, not least by enabling the communication of claims that contradict information from established medical authorities. As an example, knowledge claims about systemic side effects of the contrace
Traumatic knee injury is common in physical activity that includes jumping and cutting movements, and most commonly include anterior cruciate ligament (ACL) or meniscus injuries. Surgical or non-surgical intervention strategies may be chosen, but treatment will include a physical-therapist led physical training program. The aim of this training is to strengthen and stabilize the knee. Despite rece
The advent of PET ligands that bind tau pathology has enabled the quantification and visualization of tau pathology in aging and in Alzheimer disease (AD). There is strong evidence from neuropathologic studies that the most widely used tau PET tracers (i.e., 18F-flortaucipir, 18F-MK6240, 18F-RO948, and 18F-PI2620) bind tau aggregates formed in AD in the more advanced (i.e., ≥IV) Braak stages.

Background: Exposure to many contacts is the main risk factor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, while risk of serious disease and death is chiefly determined by old age and comorbidities. Relative and population-attributable fractions (PAFs) of multiple medical and social exposures for COVID-19 outcomes have not been evaluated among older adults. Objective
Non-bee pollinators (NBP) are a group of species with very diverse ecology. Indeed, they inhabitvarious habitats, using these as nesting sites, for shelter, as source of food and as huntingground for prey. Depending on the life stage of species, NBPs can inhabit different areas andtheir overall contribution to pollination can be diverse. For example, adult butterflies mainlyforage on nectar, where
A nursing programme in southern Sweden was revised to meet future demands. The aim of this study was to explore important conceptual areas to be included in a nursing programme in order to meet long-term societal and health care requirements. Group concept mapping (GCM), a mixed-methods approach, was used. Thirty-four experienced teachers participated. Data was collected during brainstorming sessi
Introduction: Occupation-based interventions could help to address a growing mental health crisis among young people and adolescents. To develop new interventions and avoid research waste, a review of the academic literature is needed that systematically identifies and describes interventions designed to improve the mental health and wellbeing of 11–25 year-olds. Aim: The scoping review aims to sy
