The current paper focuses on the conceptual design and numerical analysis of a four-stage centrifugal pump for the fuel system of a turbofan engine with liquid hydrogen as fuel. Liquid hydrogen is challenging at high pressures due to its special fluid properties. The design condition for the pump is set at take-off, to raise the pressure of liquid hydrogen from 6 bars at the outlet of a low-pressu
This special issue deals with temporalities in migration law with particular emphasis on the European context. At the crossroads of several legal fields, including public law, human rights law, EU law and public international law, the topic is cutting-edge in migration law. The articles collected were originally presented at a conference organized at Vrije Universiteit in Amsterdam in June 2023 an
Historically, research on nonavian reptile communication has emphasized visual, tactile, and chemical modalities. Recently, growing evidence highlights the significance of acoustic signals in intra- and interspecies interactions. Reptiles produce sounds to mediate social behaviors such as reproduction, parent–offspring interactions, and territorial defense. Many species were found to have diverse
The adsorption of soft microgels at interfaces is a key phenomenon in numerous applications, including emulsification, interfacial stabilization, and responsive coatings. In this work, we employ a combination of in situ atomic force microscopy and numerical simulations to systematically investigate the structural behavior of individual microgels at liquid-liquid and solid-liquid interfaces. By dir
The end-Permian mass extinction greatly affected the sedimentary record, but the sedimentary response was not limited to the Permian-Triassic boundary interval. This transformation extended to sedimentation that spanned the entire Early Triassic. Calcimicrobialites play an important role throughout this time interval, and at least four main events of anomalous carbonate deposition can be shown. A
Context. Studies of the internal kinematics of the LMC have provided a detailed view of its structure, largely thanks to the exquisite proper motion data supplied by the Gaia mission. However, line-of-sight (LoS) velocities, the third component of the stellar motion, are only available for a small subset of the current Gaia data, thus limiting studies of the kinematics perpendicular to the LMC dis
Based on a combination of morphometric analyses, a chloroplast DNA phylogeny, and multivariate analyses of whole genome sequence data from >300 museum samples, we discuss and evaluate the delimitation, taxonomy, and evolution of wild and escaped taxa in Mentha subgen. Mentha, focusing on the northern hemisphere. Thirteen species (Mentha aquatica, M. arvensis, M. australis, M. capensis, M. dahurica
Obesity represents a global health challenge, with a critical and urgent need for long-term, sustainable management strategies. Tirzepatide is a novel dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. At first approved for the treatment of type 2 diabetes mellitus, tirzepatide represents one of the latest clinically approved and commercia
The robotic future is nearly here, and East Asia stands at the forefront of this shift. East Asian firms innovating in this sector are backed in various ways by governments committed to competing for leadership in robotics. This field promises to unleash heightened productivity and precision in manufacturing, while the opportunities in services are also enormous. The expanded installation of robot

Background: Accurate markers for prostate cancer (PC) risk stratification could aid decision-making for initial management strategies. The 4Kscore has an undefined role in predicting outcomes after radical prostatectomy (RP). Methods: We included 1476 patients with 4Kscore measured prior to RP at two institutions. The 4Kscore was assessed for prediction of adverse pathology at RP and biochemical r
Although groundwater serves as the predominant source of drinking water across many rural regions and certain urban areas of Rwanda, little is known about this resource. Anthropogenic impacts, such as faecal contamination, as well as geogenic water quality problems, including elevated arsenic, fluoride, iron, and manganese, are among the issues of concern for groundwater quality in Rwanda. Long-te
Structure analysis of partially depolymerized methyl cellulose was performed by nanoelectrospray ionization tandem mass spectrometry (nano-ESI-MS/MS) and by matrix-assisted laser desorption/ionization tandem mass spectrometry (MALDI-MS/MS). Dimethylamine (DMA) was used for the first time as a reducing end derivatization reagent for oligosaccharides. This is an attractive reagent since it could be
BACKGROUND Marked changes have occurred in in vitro fertilization (IVF) methodology during the past 25 years but also in characteristics of couples undergoing treatment. METHODS This study was based on 27 386 women undergoing IVF treatment from 1982 to 2006 and giving birth to 31 850 infants. Outcomes of deliveries were studied using Swedish health registers. Comparisons were made with all deliver
