A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was succes

Despite the recent experimental and theoretical progress in the investigation of the nuclear fission process, a complete description still represents a challenge in nuclear physics because it is a very complex dynamical process, whose description involves the coupling between intrinsic and collective degrees of freedom, as well as different quantum-mechanical phenomena. To improve on the existing

Background: SARS-CoV-2 mRNA vaccination has been associated with both side effects and a reduction in COVID-related complaints due to the decrease in COVID-19 incidence. We aimed to investigate if individuals who received three doses of SARS-CoV-2 mRNA vaccines had a lower incidence of (a) medical complaints and (b) COVID-19-related medical complaints, both as seen in primary care, when compared t

Malaria är världens dödligaste parasitsjukdom som årligen drabbar nästan 250 miljoner människor, varav 95% av fallen sker i Subsahariska Afrika. Över en halv miljon människor dör till följd av malaria varje år där majoriteten av dem är barn. Sjukdomen sprids av myggor som är infekterade av encelliga parasiter av släktet Plasmodium. Det finns fem Plasmodium-arter som kan smitta människor, varav P. The widespread and infectious disease malaria is still prevalent and endemic in many countries around the equator. The treatment and prevention of malaria is hampered by the rapid development of resistance in parasites against antimalarial drugs. In recent years, metal derivatives of chloroquine, the previously dominant antimalaria drug, have been studied as alternatives to overcome the resistance

Narratives of the Indian revolutionary movement in exile have often focused on abstract notions of ‘London’—with a particular focus on ‘India House’ in Highgate—or ‘Paris’ without taking into account specific geographies of Indian anti-colonialism within these imperial metropoles. Drawing on addresses provided in intelligence reports, this article takes a spatial approach and explores how particul

När ordet alienation nämns råder ofta en känsla av isolering och ensamhet, och vissa tänker på alienation från hemlandet. Alienation är ett begrepp som har många dimensioner och har behandlats av många tänkare. Denna studie handlar om alienation och kreativitet. Den alienation som avses här är, social alienation, själv-alienation och kulturell alienation. Syftet med studien är att belysa om det f

Population decline in rural areas is observed in almost every European country. In Croatia, there are no meaningful strategies to mitigate the consequences of depopulation. As a result, many rural communities have already disappeared, while more are becoming unsustainable. Krapina-Zagorje is a region severely impacted by the shrinking and aging of its population. This thesis approaches depopulatio

The aim of this thesis is to study teachers’ perception of children’s ability to evacuate, thus learning about children’s evacuation behavior. Questions of interest are teachers’ perception of children’s ability to evacuate, their behavior, if there are any misconceptions in the teachers’ perception and how fire evacuation drills influence the teachers’ perceptions. This was done through a questio

To improve heat dissipation and temperature uniformity for the lithium-ion battery module of electric vehicle, the immersion phase change cooling characteristics of R1233ZD(E)/Ethanol mixed refrigerant were studied experimentally in a staggered battery module, which is composed of 50 batteries. At 101.3 kPa saturated vapor pressure, coupled wall boiling and forced convection heat transfer was anal

The high pulse intensity and repetition rate of the European X-ray Free-Electron Laser (EuXFEL) provide superior temporal resolution compared with other X-ray sources. In combination with MHz X-ray microscopy techniques, it offers a unique opportunity to achieve superior contrast and spatial resolution in applications demanding high temporal resolution. In both live visualization and offline data

Background and aims: The associations of vitamin D level with venous thromboembolism (VTE) reported in observational studies, whereas these causal associations were uncertain in European population. Therefore, we used Mendelian randomization (MR) method to explore the causal associations between 25-hydroxyvitamin D (25(OH)D) concentrations and the risk of VTE and its subtypes [including deep vein

BACKGROUND: Autoantibodies are common in glomerulonephritis, but the clinical benefit of rapid elimination is not determined, even in anti-glomerular basement membrane (GBM) disease. Even less is known about the importance of autoantibody characteristics, including epitope specificity and IgG subclass distribution. By utilizing samples from the GOOD-IDES-01 trial, where imlifidase, cleaving all Ig

CsPbI3 nanocrystals (CPI NCs) have become a trending research topic due to their impressive potential in functional optoelectronic devices and optical gain applications. Their optical responses are governed by carrier dynamics, which is greatly influenced by temperature and corresponding phase structure due to the effects of inherently electron-phonon coupling. Notably, CPI NCs have been identifie

We have employed the cranked Nilsson-Strutinsky and cranked Nilsson-Strutinsky-Bogoliubov methods to predict the structure of the observed high-spin rotational bands in Nd137. Our study is motivated in particular by a previous observation of a rotational band more than 4 MeV above yrast. We discuss both possible interpretations of this band and in this connection also the HD band and the terminati

In September 1912, the Russian author Maxim Gorky wrote to the Paris-based Indian revolutionary Madame Cama and asked her to write an article on Indian women and their role in the Indian freedom struggle. Their correspondence highlights several issues: Cama’s central role among Indian and anticolonial nationalists from across the world in early twentieth-century Paris; the inspiration from the 190

The dispute over the Diaoyu/Senkaku Islands is generally analysed as a Sino-Japanese competition over material and strategic interests, regional preponderance, and nationalistic symbolism. Yet, such explanations cannot fully explain the endurance of the conflict and overlook its origin in the period leading up to the UN’s derecognition of Taiwan’s sovereignty in 1971. Drawing on the concept of ont

Non-exhaust emissions from road transport are an important PM10 source, causing negative health effects. Measures to reduce particulate pollution from roads include dust suppression using hygroscopic solutions and road sweeping. This study investigates if porous pavements, generally used for their better noise reduction and water drainage capacity, can also improve air quality. Atmospheric measure

Background: Collegial midwifery assistance during the active second stage of labor that involves a second midwife being present has been shown to reduce severe perineal trauma (SPT) by 30%. The aim of this study was to investigate primary midwives' experiences of collegial midwifery assistance with the purpose of preventing SPT during the active second stage of labor. Methods: This study uses an o

We consider entropy conservative and dissipative discretizations of nonlinear conservation laws with implicit time discretizations and investigate the influence of iterative methods used to solve the arising nonlinear equations. We show that Newton's method can turn an entropy dissipative scheme into an anti-dissipative one, even when the iteration error is smaller than the time integration error.
