Nuclear distributions affect many aspects of atomic spectra, making atomic physics a useful tool to study also nuclear properties. Relativistic coupled-cluster calculations for the 7s and 7p states in Fr are presented and applied to binding energies, and to electronic factors for the field isotope shift. The result, Fκ = -21.0 GHzfm-2 for the 7s-7p3/2 transition, leads to revised values for the ch
A diagonalisation procedure of the Foldy-Wouthuysen type is considered for the single-electron Dirac Hamiltonian as a basis for many-body applications. A modified procedure is suggested. In the diagonalisation procedure the Dirac equation is completely decoupled into two equations of the Pauli type. The expressions for positive- and negative-energy projection operators in the transformed basis are
Nickel phosphide is a valuable material in high-temperature brazing and joining applications, offering excellent thermal stability for temperatures up to 400°C. Nickel phosphide is used as powder form for joining applications and therefore it is imperative to study the formation as well as interaction of Ni2P particles with adjacent particles in an in-situ/in-operando manner for high temperature j
INTRODUCTION: Endovascular thrombectomy (EVT) is a significant improvement in the care of acute ischemic stroke (AIS) patients, but only a small portion of patients receive treatment. Our aim was to analyze EVT implementation in Sweden according to a set of key performance indicators (KPIs) for procedural and implementational effectiveness. METHODS: A nationwide prospective registry-based obs
The formation of copper phosphide phases during brazing can negatively impact the mechanical properties of copper joints and the overall performance of the resulting product. For instance, copper tubes in air conditioning heat exchangers are brazed using Cu-P filler alloy, resulting in unnecessary brittle Cu₃P compounds. This study investigates a novel process of dephosphorization of copper phosph

This paper provides an overview of both long-standing and new legal and policy developments concerning Environmental Human Rights Defenders (EHRDs). The focus is on four major components: i) observing different approaches and understandings about EHRDs; ii) analysing the content of international obligations concerning EHRDs and mechanisms for reviewing implementation and accountability; iii) discu
Background: The EAT-Lancet Commission has proposed a global reference diet aimed at promoting both human health and environmental sustainability. While adherence to this dietary pattern has been associated with reduced risks of chronic disease and lower environmental impact, concerns remain about its ability to meet nutritional requirements - particularly among older adults. The aim was to explore
Human diets play a crucial role in both human health and environmental sustainability. In 2019, the EAT-Lancet Commission on healthy diets from sustainable food systems introduced the EAT-Lancet planetary health diet, a universal reference diet designed to promote human health while minimizing environmental degradation. It is a predominantly plant-based dietary pattern, rich in whole grains, veget
Background and aims: The EAT-Lancet Commission proposed a healthy dietary pattern to prevent diet-related diseases while promoting planetary sustainability, but little is known regarding its associations with type 2 diabetes (T2D) and metabolic dysfunction-associated steatotic liver disease (MASLD), both of which are highly prevalent and frequently co-exist. We aimed to assess association of thi
PurposeIn this paper, we discuss common pitfalls in producing review articles for publication in academic journals, offering guidance to minimize rejection rates. We highlight the dual core features of systematicity (i.e. rigor and transparency) and generativity (i.e. advancing knowledge) in review papers. Thereby, we aim to help researchers deal with the abundance of guidelines and create publish

In this thesis, the inherent oxidation resistance of Al-Co-Cr-Fe-Ni based high entropy alloys have been remarkably enhanced by increasing the grain boundary area and recognizing the influence of the in situ Al2O3 nano-dispersoids. Isothermal continuous oxidation test based on thermogravimetric analysis (TGA) as well as extensive furnace oxidation, were conducted in the elevated temperature range o
Introduction Cluster analysis, a machine learning-based and data-driven technique for identifying groups in data, has demonstrated its potential in a wide range of contexts. However, critical appraisal and reproducibility are often limited by insufficient reporting, ultimately hampering the interpretation and trust of key stakeholders. The present paper describes the protocol that will guide the d
Ammonia is considered a promising carbon-free fuel for marine engines, yet challenges persist in utilizing ammonia as a carbon-free marine fuel due to its inherently low reactivity and significant emissions of NOx and N2O. To address these issues, advanced combustion strategies, such as ammonia/diesel dual-fuel Reactivity-Controlled Compression Ignition (RCCI), have been proposed. This thesis pres
Tendons are known to adapt their structural and mechanical properties in response to mechanical loading, but the precise mechanisms underlying this adaptation remain poorly understood. A previous study on rat Achilles tendons compared the effect of unloading (Botox injections and orthosis) with free cage activity (full loading) and revealed that unloading impaired the mechanical response and resul
Introduction: The refractory period and conduction delay of the atrioventricular (AV) node play a crucial role in regulating the heart rate during atrial fibrillation (AF). Beat-to-beat variations in these properties are known to be induced by the autonomic nervous system (ANS) but have previously not been assessable during AF. Assessing these could provide novel information for improved diagnosis
