Analysis of naturally occurring isotopic variations is a promising tool for investigating Zn transport and cycling in geological and biological settings. Here, we present the recently installed double-spike (DS) technique at the MAGIC laboratories at Imperial College London. The procedure improves on previous published DS methods in terms of ease of measurement and precisions obtained. The analyti
Popular Abstract in English Imagine a solar powered flash light. Each photon absorbed by the flash light’s solar cell creates electric energy and the flash light’s light source converts the electrical energy again into photons. The purpose of such a device may be questionable, because you would be surprised if it would create more light than what it absorbs. However, under certain conditions it isIn this thesis the luminescence properties of highly doped semiconductors are studied with focus on degenerately n-doped InP. It is demonstrated how photoluminescence measurements on degenerately doped semiconductors allow an estimation of the doping concentration without need for electrical contacts. The degenerate doping can furthermore reveal the conduction band structure for energies higher th
Objective: To highlight experiences from a personal data incident, which occurred during recruitment for a project focused on how housing choices and relocation are related to active and healthy ageing. Results: Based on established collaboration, the researchers and representatives of housing companies planned for recruitment. Invitations to participate was distributed to persons registered with
In previous years, substantial research has focused on walkability, primarily examining how the built environment affects walking behavior. However, these studies have predominantly defined walkability through physical and social factors, with limited exploration of its spatial dimension. This article seeks to address this gap by examining the spatiality of walkability through Lefebvre’s spatial tIn previous years, substantial research has focused on walkability, primarily examining how the built environment affects walking behavior.

Background: Amyotrophic lateral sclerosis (ALS) is invariably fatal but there are large variations in the rate of progression. The lack of predictability can make it difficult to plan clinical interventions. This includes the requirement for gastrostomy where early or late placement can adversely impact quality of life and survival. Methods: We designed a model to predict the timing of gastrostomy
A search for heavy Majorana neutrinos in scattering of same-sign W boson pairs in proton–proton collisions at s=13 TeV at the LHC is reported. The dataset used corresponds to an integrated luminosity of 140 fb−1, collected with the ATLAS detector during 2015–2018. The search is performed in final states including a same-sign ee or eμ pair and at least two jets with large invariant mass and a large
This study examines how public transport passengers experience and use travel time and under what conditions they are particularly concerned about shorter travel time. Using a survey of Swedish public transport users and a follow-up focus group, we compare current patterns with a similar 2009 study. Findings indicate a slight decline in perceived value of travel time, coinciding with a marked redu
Objective: Survivors of childhood, adolescent, and young adult (CAYA) cancer have an increased risk of metabolic syndrome (MetS). MetS describes the clustering of cardiovascular risk factors including overweight or obesity, hypertension, (pre)diabetes, and dyslipidaemia. While associated cardiovascular sequelae can be serious, MetS is preventable, manageable, and potentially reversible with the ap
In the last decade, the idea of total defence – a whole-of-society approach integrating civilian and military capabilities – has gained renewed prominence in Europe, including within the European Union (EU). Concurrently, the concept of strategic autonomy – the EU’s ability to act independently – has emerged as a central feature in its security policy, driving ambitions for ‘a quantum leap forward
The spectrum of frontotemporal dementia/amyotrophic lateral sclerosis (FTD/ALS) and Huntington disease (HD) are fatal neurodegenerative disorders with no major disease-modifying therapies. Recent work has shown that the hallmark pathological proteins TAR DNA binding protein of 43 kDa (TDP-43) in FTD/ALS and mutant huntingtin (mHTT) in HD may be interlinked. Furthermore, these disorders share early
BACKGROUND: Counting very low levels of leukocytes is technically challenging but mandatory for quality control of leukocyte-depleted plasma. Established assays, such as flow cytometry and counting in the Nageotte chamber, are laborious and expensive. The aim of this study was to test two alternative assays, the cerebrospinal fluid program in the routine hematology analyzer ADVIA 2120 and a fluore
Introduction The Problematic Experience of Therapy Scale (PETS) identifies barriers to home-based exercise programs but has not been validated in hand therapy populations. This study aimed to translate the extended PETS into Swedish and evaluate its content and construct validity in patients undergoing early sensory relearning following peripheral nerve injury.Methods The PETS was translated into
A search for pair production of vector-like leptons coupling to first- and second-generation Standard Model leptons is presented. The search is based on a dataset of proton-proton collisions at s = 13 TeV recorded with the ATLAS detector during Run 2 of the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb−1. Events are categorised depending on the flavour and multiplicity
This paper presents a search for supersymmetric particles in models with highly compressed mass spectra, in events consistent with being produced through vector boson fusion. The search uses 140 fb−1 of proton-proton collision data at s = 13 TeV collected by the ATLAS experiment at the Large Hadron Collider. Events containing at least two jets with a large gap in pseudorapidity, large missing tran
Precipitates of the topologically close-packed (TCP) phases can significantly impact a material’s mechanical and fracture properties. This theoretical study uses ab initio modeling to investigate the σ phase of WOs, focusing on composition-dependent mechanical and fracture-related properties. We find the effect of Os on WOs σ to be stronger than that of Re in WRe σ phase, with the WOs phase exhibiPrecipitates of the topologically close-packed (TCP) phases can significantly impact a material’s mechanical and fracture properties.

This study evaluates the practice of the security provisions in ADR (the Agreement concerning the International Carriage of Dangerous Goods by Road) for the first time. A qualitative case study of an organisational field was undertaken, comprising fourteen semi-structured interviews with four government agencies and eight logistics firms in transportation of dangerous goods in Sweden. Four evaluat
