While NH3 has gained a lot of interest as a potential carbon-free fuel, at present, there are notable disagreements when it comes to predictions of some of its combustion characteristics, such as burning velocity or species mole fractions, in particular of NOx, which have the potential to cause significant harm to both human health and the environment. Nevertheless, because the NH3 flame presents

BackgroundObsessive-compulsive symptoms (OCS) often emerge during childhood and adolescence, and two aetiological models have been proposed. According to the first model, maladaptive cognitive beliefs facilitate the transformation of transient intrusive thoughts into OCS. The second model suggests that dysfunctional cognitive beliefs develop in response to increased levels of OCS. Few studies have

Challenging conventional provider-oriented perspectives on older adults' spatial realities, this study explores how community-dwelling care users in Sweden manage their home environments. It investigates how older adults use the welfare system and coordinate widely available but disparate material and social resources to achieve a spatially sustainable ageing-in-place. Research on domiciliary care

Cross-system fluxes of aquatic insects rich in omega-3 long-chain polyunsaturated fatty acids (ω-3 LC-PUFAs), specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), may subsidise insectivorous vertebrates that are suffering due to terrestrial insect declines. The benefits of high ω-3 LC-PUFA diets, such as improved growth and immunocompetence, have previously been demonstrated fo

Population growth and climate change have accelerated groundwater depletion globally. Interferometric synthetic aperture radar (InSAR) is a fairly new satellite remote sensing technique based on SAR images that offers a high-accuracy monitoring system of land surface motion driven by groundwater level changes in time and space that can never be achieved with point-in-situ measurements. In producti

The long-term provision of ocean ecosystem services depends on healthy ecosystems and effective sustainable management. Understanding public opinion about marine and coastal ecosystems is important to guide decision-making and inform specific actions. However, available data on public perceptions on the interlinked effects of climate change, human impacts and the value and management of marine and

Whereas theoretical attacks on standardized crypto primitives rarely lead to actual practical attacks, the situation is different for side-channel attacks. Improvements in the performance of side-channel attacks are of utmost importance.In this paper, we propose a framework to be used in key-recovery side-channel attacks on CCA-secure post-quantum encryption schemes. The basic idea is to construc

The paper presents novel studies on the impact of different ignition control parameters on combustion stability and spark plug wear. First, experimental results from a 32.4-liter biogas fueled large bore single cylinder spark ignition engine are discussed. Two different ignition systems were considered in the experiment: a DC inductive and an AC capacitive. The spark plugs used in the experiment w

Drought monitoring and prediction have important roles in various aspects of hydrological studies. In the current research, the standardized precipitation index (SPI) was monitored and predicted in Peru between 1990 and 2015. The current study proposed a hybrid model, called ANN-FA, for SPI prediction in various time scales (SPI3, SPI6, SPI18, and SPI24). A state-of-the-art firefly algorithm (FA)
