We present an adaptive Discontinuous Galerkin discretization for the solution of porous media flow problems. The considered flows are immiscible and incompressible. The adaptive approach implemented allows for refinement/coarsening in both the element size and the polynomial degree. The method is evaluated using homogeneous and heterogeneous test cases.
Vi lever i en tid när gränsöverskridande rättsförhållanden blir en allt mer naturlig del av vår vardag. Med det ökade antalet internationella rättsförhållanden ökar också antalet potentiella tvister som har anknytning till mer än ett land. Makar med olika medborgarskap kanske kommer att vilja skiljas och den köpta produkten från det andra landet kanske var felaktig. När tvister av den här typen sk
The rise of online brand communities has transformed consumer/brand interactions, thus affecting consumer engagement and its nomological network. However, scholarly understanding regarding the effect of consumer values on their online engagement remains tenuous. Addressing this gap, we conceptualize a model that attempts to understand the relative effect of consumers’ values (terminal and instrume
Purpose: In this study, numerical simulations are performed to compare the adiabatic film cooling effectiveness and reveal the difference of film cooling mechanisms of two models with the same geometries and cross-section areas of film holes’ exits at three typical blowing ratios (M = 0.5, 1 and 1.5). The two models are an elliptical model and a cylindrical model with 90° compound angle, respectiv
Intraosseous (IO) access is normally reserved for emergencies and critical care conditions when venous cannulation is not possible. Nonetheless, we present a case of IO insertion to a 56-year-old man, tetraplegic for many years due to progressive spinal muscular atrophy and with refractory suffering. The IO access was used for palliative sedation with propofol in a home care setting. The patient d
Background: The power and influence of the hidden curriculum - culturally situated norms and values - onlearning opportunities is a growing concern in medical education. However, while medical schools producediversity and equal treatment policies, efforts towards surfacing and addressing equal opportunities in theclinical learning environment trail behind.Summary of Work: To better understand how
This paper exploits an arbitrary university eligibility rule in Sweden combined with regression discontinuity to estimate the impact of university education on health derived demand for medical care. We find a clear jump in university attendance due to university eligibility of between 10 and 14 percentage points. For females this implies a 30-40% drop in self-harm. For males it coincides with red
Human activities and climate change affect hydrological and sedimentological characteristics within catchments. For arid and semiarid areas this induces direct negative economic and environmental consequences on society. In fact, stability in the rainfall regime and less siltation trapped in reservoirs mean more water for irrigation, water supply, and better flood control. This is especially impor
Purpose: The fluid flow in a rotating channel is obviously different from that in a stationary channel due to the existence of Coriolis force, which, in turn, enhances the heat transfer on the trailing side and reduces the heat transfer on the leading side. The purpose of this paper is to study various rib configurations combined with channel orientation on heat transfer and frictional loss in a r
Purpose: This study aims to clarify the mechanism of film hole location at the span-wise direction of an internal cooling channel with crescent ribs on the adiabatic film cooling performance, three configurations are designed to observe the effects of the distance between the center of the ellipse and the side wall(Case 1, l = w/2, Case 2, l = w/3 and for Case 3, l = w/4). Design/methodology/appro
The additional passing lanes and 2+1 roads improve significant road safety. Studies indicate sections with additional passing lanes (relief or alternately), which may cause reduction in the number of accidents by 50%. However, how geometric design affects the safety performance of such sections is not in depth investigated. Previous studies are carried out with two approaches, i.e. the most often,
Purpose: The purpose of this study is to enhance the thermal performance in the labyrinth channel by different ribs shape. The labyrinth channel is a relatively new cooling structure to decrease the temperature near the trailing region of gas turbine. Design/methodology/approach: Based on the geometric similarity, a simplified geometric model is used. The k − ω turbulence model is used to close th
Background: Frailty is associated with poor 30-days survival after in-hospital cardiac arrests (IHCA). The aim was to assess how pre-arrest frailty was associated with long-term survival, neurological function and patient-reported outcomes in elderly survivors after IHCA. Methods: Patients aged ≥ 65 years with IHCA at Karolinska University Hospital between 2013–2021 were studied. Frailty was asses
Meta-analysis is a statistical method used in evidence synthesis for combining, analyzing and summarizing studies that have the same target endpoint and aims to derive a pooled quantitative estimate using fixed and random effects models or network models. Differences among included studies depend on variations in target populations (ie, heterogeneity) and variations in study quality due to study d
Bayesian inference under a set of priors, called robust Bayesian analysis, allows for estimation of parameters within a model and quantification of epistemic uncertainty in quantities of interest by bounded (or imprecise) probability. Iterative importance sampling can be used to estimate bounds on the quantity of interest by optimizing over the set of priors. A method for iterative importance samp
The food industry is actively adopting carbon neutral strategies aligned with the principles of Industry 4.0 to establish long-term goals for reducing carbon emissions and accelerating the transition to a low-carbon food production industry. Industry 4.0, often referred to as the fourth industrial revolution, emphasizes the integration of digital technologies, automation, and data exchange into ma
