OBJECTIVES: To investigate the optimal duration of venoarterial extracorporeal membrane oxygenation (ECMO) for cardiogenic shock refractory to medical therapies after cardiac surgery and whether its prolonged use is justified. DATA SOURCES: Previously published articles on postcardiotomy venoarterial ECMO. STUDY SELECTION: Articles reporting on the early outcome after postcardiotomy venoarterial E

Nanowire quantum dots have shown promise as energy filters in thermoelectric applications. However, anomalous effects in the thermocurrent have been observed when heat is applied in close proximity to the quantum dot. This work began as an experimental investigation but transitioned to a data analysis project due to hardware failure. Using previously acquired experimental data, we compare the meas

Objective: To assess foetal circulating free foetal haemoglobin (fHbF) levels and heme defences, correlated to foetal circulatory biometry and foetal sex in severe early-onset foetal growth restriction (FGR). Design, Setting and Population: A prospective study severe early-onset foetal growth restriction pregnancies with close clinical management (estimated foetal weight (EFW) < 3rd centile and <

Background: Composite outcome measures aim to provide a more holistic view when determining the effectiveness and safety of surgical interventions. Recently, 'Ideal Outcome' (IO) harmonized the European and American composite outcome of pancreatic surgery. The rate of IO after pancreatoduodenectomy was 54% but is unknown after left pancreatectomy(LP). Methods: This transatlantic analysis included

The dynamics of chemical reactions in solution are of paramount importance in fields ranging from biology to materials science. Because the hydrogen-bond network and proton dynamics govern the behavior of aqueous solutions, they have been the subject of numerous studies over the years. Here, we report the observation of a previously unknown associative state in the hydroxide ion that forms when a

Areas experiencing conflict are challenging to examine due to limited accessibility. Remote sensing is a valuable tool that can be used to evaluate the effects of conflict on the environment. Northwestern Syria hosts most of the country’s remaining Mediterranean forests, an ecosystem that is ecologically significant for regulatory ecosystem services. Since 2011, Syria has experienced conflict, whi

Climate change is expected to alter soil nutrient availability and microbial community functionality. Inputs of labile carbon (C) from root exudates can stimulate the decomposition of soil organic matter (SOM) in a phenomenon known as “priming”; driven by microbial demand for limiting resources. Climate-driven changes in resource availability may therefore influence soil susceptibility to priming,

Climate change intensifies extreme weather events, especially droughts, with severe consequences to the functional integrity of terrestrial high-latitude ecosystems. As essential global water and carbon balance regulators, these sensitive ecosystems respond to increased warming and altered hydrology with modulated resource use efficiencies. This study aimed to investigate the impacts of various hy

Solar energy is one of the most promising solutions for the energy crisis due to its wide availability and cost-effectiveness. Solar cells have long been used to convert solar energy to electricity, but due to the high cost and difficult processability of the widely available and commercialized silicon solar cells, replacing them with new technology has always been of interest for researchers. Rec

Att göra städer grönare är en central strategi för klimatanpassning i allt varmare urbana miljöer. Många studier undersöker säsongsvariationer i urban fenologi, men det är mycket få av dem som fokuserar på kontinuerliga och dynamiska fenologiska mått. Denna studie analyserar sambandet mellan Plant Phenology Index (PPI) och markytetemperatur (Land Surface Temperature, LST) i Bryssel under år 2022, Urban vegetation is a key strategy for climate adaptation in increasingly dense and warming cities. While some studies look at urban seasonal trends in plant phenology, fewer look at continuous dynamic phenology measures. This study investigates the relationship between the Plant Phenology Index (PPI) and Land Surface Temperature (LST) across Brussels in 2022, using satellites Sentinel-2-derived P

Att vilja vara kvar: faktorer som får vårdens medarbetare att trivas Sjukvården i Sverige står inför en av de största utmaningarna någonsin: hur ska vi säkra att det finns tillräckligt med kompetent personal i framtiden – både i den offentliga och privata vården? Regeringen satsar stora resurser på att kartlägga behoven och hitta lösningar, men det krävs fortfarande mer forskning för att verkligeThe Swedish healthcare system is facing a substantial challenge in competence provision, with skilled staff needed in both the private and public sectors. The Swedish government is investing heavily in initiatives and mapping projects aimed at securing future competence supply. This study aims to identify which factors have the greatest impact on healthcare employees' decisions to either leav

Bakgrund: Hälso- och sjukvårdspersonal kan uppleva arbetsrelaterad stress till följd av exempelvis höga krav, tidspress och otillräckligt stöd på arbetsplatsen. Stress kan leda till allvarliga psykiska och fysiska hälsoproblem, särskilt när den blir långvarig. Sjuksköterskeyrket är ofta stressigt då sjuksköterskor är särskilt utsatta på grund av höga krav och låg kontroll. Syfte: Studiens syfte va

Forest plantations play a crucial role in the livelihoods of Rwandan people. They provide valuable wood resources, such as timber and biomass energy. The first plantations created in the colonial period from 1920 to 1948 contained only exotic Eucalyptus species, which is thought to out-perform native species in terms of more rapid wood production. Over time, this resulted in the domination of non-

The selective separation of glycoproteins is essential in biomarker discovery, glycoprotein profiling and analysis. Glycosylation of proteins has a major impact on their structure and function. The heterogeneity of glycosylation patterns makes the glycomic profiling extensive, but nonetheless of upmost importance for the deeper understanding of metabolic pathways, cell signalling and the impact of

Taking advantage of the relatively automatic and easy operation procedure, continuous-flow catalysis has become a promising wastewater treatment technique for organic dye removal. However, developing suitable packing catalysts with favorable activity and low flow resistance remains a challenging task for the construction of continuous-flow catalytic systems. In this paper, we report the preparatio

Two cast Mg–Al–Ba–Ca alloys, DieMag633 and DieMag844, are the focus of this study. Their microstructureMicrostructure consists of a eutectic Ca-rich structure, the lamellar Al2Ca, and of a hard, compact and brittle interdendritic Ba-rich phase, the Mg21Al3Ba2 phase. Both phases have a much higher hardness than the α-Mg matrix and strongly influence the crack propagationCrack propagation under quas

Physics-informed neural networks integrate physical laws into machine learning models to solve differential equations. This thesis investigates an inverse physics-informed neural network framework for estimating viscosity in Tetra Pak’s injection molding process, where direct measurements are not possible. By enforcing the Navier-Stokes equations and using sparse velocity and pressure data, a virt

As multistakeholder institutions become increasingly central to global governance, questions of how these hybrid organizations establish and maintain legitimacy have gained growing academic attention. This thesis conducts a systematic comparative analysis of the self-legitimation practices of two prominent multistakeholder initiatives: Fairtrade International and the Internet Corporation for Assig

This master’s thesis explores municipal and civil society refugee support practices in Berlin and Brandenburg, Germany during the current crisis of insecurity. Centering the question of how local-level support can oppose an excluding global precarization of refugees, the thesis works with an experiential puzzle to explore the subjective views of civil society and municipal actors in the realm of m
