En själ som Brutus’ och behag som Kleopatras. Så karaktäriserar upplysningsfilosofen Denis Diderot (1713–84) i ett brev den ryska kejsarinnan Katarina den stora, sedan han mött henne i S:t Petersburg i samband med en resa till Ryssland 1773–74. Diderot förespråkade jämlikhet, men var monarkist. Den perfekta regenten var en furste med det egna folkets väl som mål, menade han.En sådan filosofi kunde
Recycling trade has become an important initiative for major powers to address rare earth supply risks. With the help of recycling quality evaluation model, competitive intensity model, complex network method, and GIS analysis, the dynamics and characteristics of the global rare earth recycling trade network are revealed in this study. The results show that the global rare earth recycling market i

Genital self-mutilation (GSM) is a rare phenomenon encountered mostly within the context of severe mental illness. The following case report highlights a rare case of self-inflicted total penile self-amputation in a patient with a psychiatric history of polydrug abuse and attention deficit disorder (ADD). The patient engaged in penile self-amputation under the influence of command hallucinations a
TikTok’s viral short-video app has seen tremendous global growth, but its adoption in foreign policy and digital diplomacy is still low. Some diplomatic actors have refrained from developing a presence on TikTok due to geopolitical concerns emerging from TikTok’s Chinese ownership. Other diplomatic actors have established a presence on the platform due to its ability to make content with high enga
We studied the impact of estimated glomerular filtration rate (eGFR) based on either creatinine or cystatin C, or in combination, on vascular aging (aortic stiffness) and central hemodynamics (central systolic blood pressure) in a Swedish urban population with median 17 years of follow-up. Participants (n = 5049) from the population-based Malmö Diet and Cancer Study that underwent baseline examina
The geologically complex Kyzylzharma groundwater field is located in the south-central part of Kazakhstan in the lower Syr Darya Basin. It supplies the 243,000 population of Kyzylorda City by drinking and agricultural water needs. Numerical modeling was used to predict the consequences of increased groundwater withdrawal for future water supply needs. The results displayed a mean squared error for
Kazakhstan is facing increasing water scarcity due to climate change and transboundary international water diversions. For this reason, low-quality water with high mineral content needs to be increasingly used in the future. A way to improve water quality for consumptive use is membrane treatment technology. In view of this, we investigated a new type of synthetic spatial-globular structure (SGS)
Although urban greening is universally recognized as an essential part of sustainable and climate-responsive cities, a growing literature on green gentrification argues that new green infrastructure, and greenspace in particular, can contribute to gentrification, thus creating social and racial inequalities in access to the benefits of greenspace and further environmental and climate injustice. In
Accurately scheduling dwell times is vital to ensure punctual and reliable railway services, but the stochastic nature of dwell times makes this a non-trivial task. An important step towards scheduling accurate dwell times is to gain an in-depth understanding of the mechanics that influence dwell times, which is commonly done by modelling the mean dwell time. It is, however, of more interest to un
Weather impacts several aspects of our daily life, of which the way we travel is one. The relationship between weather phenomena and ridership of trains has not received much attention previously. The study we present here aims to understand the impact of temperature, wind, and precipitation on passenger volumes for commuter trains. To do so we make use of automatic passenger count and weather dat
Municipal climate resiliency and re-naturing plans are promoting greening and green (re)development, such as the inclusion of new parks, greenways, or rehabilitated shorelines, frequently as a-political, win-win solutions for all residents. Greenwashing and (re)development of green amenities in vulnerable neighborhoods—those often most in need of support toward resilience and adaptation—expose res
Characterization of emissions from fires in a laboratory-controlled environment are presented in this report. The project is initiated by the CERN HSE Unit and is called FIRIA, Fire-Induced Radiological Integrated Assessment. The objective of FIRIA is to enhance the knowledge of aerosols emitted from fires in order to develop dispersion models of radiologically-activated material in case of fire.
To study the impact of additively manufactured (AM) roughness on fluid flow and heat transfer, we performed a series of high-fidelity large-eddy simulations on turbulent heat transfer over a three-dimensional AM rough surface with varying bulk Reynolds number and average roughness height values. We considered rough surfaces created using AM techniques at Siemens based on Nickel Alloy IN939 materia
Aquaporin-0 (AQP0) is the main water channel in the mammalian lens and is involved in accommodation and maintaining lens transparency. AQP0 binds the Ca2+-sensing protein calmodulin (CaM) and this interaction is believed to gate its water permeability by closing the water-conducting pore. Here, we express recombinant and functional human AQP0 in Pichia pastoris and investigate how phosphorylation
Background: In image processing for activity quantification, the end goal is to produce a metric that is independent of the measurement geometry. Photon attenuation needs to be accounted for and can be accomplished utilizing spectral information, avoiding the need of additional image acquisitions. The aim of this work is to investigate the feasibility of 177Lu activity quantification with a small
Ribbed channel flows are encountered in numerous engineering applications to promote turbulence and enhance heat transfer in various cooling passages, e.g., in turbine blades and at combustor walls. Numerical simulations have become an increasingly useful tool for studying the behavior of fluids in rib-roughened channels to provide insights into the complex turbulence structures and flow separatio
Of concern is the fractional Kadomtsev–Petviashvili (fKP) equation and its lump solution. As in the classical Kadomtsev–Petviashvili equation, the fKP equation comes in two versions: fKP-I (strong surface tension case) and fKP-II (weak surface tension case). We prove the existence of nontrivial lump solutions for the fKP-I equation in the energy subcritical case α>45 by means of variational method
