Ordinary salt, NaCl, has many properties suitable for dosimetry and has been suggested for both retrospective and prospective optically stimulated luminescence (OSL) dosimetry. Lately, the focus has been on NaCl that is compressed into solid pellets, as this improves both its handling and dosimetric properties. In this project, the energy dependence of NaCl pellets produced in-house was investigat
This paper presents a search for direct top squark pair production in events with missing transverse momentum plus either a pair of jets consistent with Standard Model Higgs boson decay into b-quarks or a same-flavour opposite-sign dilepton pair with an invariant mass consistent with a Z boson. The analysis is performed using the proton–proton collision data at s=13 TeV collected with the ATLAS de
Next generation targeted sequencing of HLA-DRB1, -DRB3, -DRB4 and -DRB5 (abbreviated as DRB345) provides high resolution of functional variant positions to investigate their associations with type 1 diabetes risk and with autoantibodies against insulin (IAA), GAD65 (GADA), IA-2 (IA-2A) or ZnT8 (ZnT8A). To overcome exceptional DR sequence complexity due to high polymorphisms and extended linkage-di
In this work, a carbon felt electrode (CFE) was modified with a multiwalled carbon nanotube-gold-platinum (MWCNT-Au-Pt) hybrid nanomaterial and integrated with an osmium redox polymer (OsRP, [Os(2, 2’-bipyridine)2(poly-vinylimidazole)10Cl]Cl) and Gluconobacter oxydans DSM 2343 (G. oxydans) cells. The developed electrode was used as the bioanode in a 5.0 mM K3Fe(CN)6mediator containing phosphate bu
The mechanisms and role of nerve cell death after traumatic brain injury (TBI) are not fully understood. The authors investigated the effect of pretreatment with the oxygen free radical spin trap alpha-phenyl-N-tert-butyl-nitrone (PBN) on the number of neurons undergoing apoptosis after TBI in rats. Apoptotic cells were identified by the TUNEL method combined with the nuclear stain, Hoechst 33258,
This article reports on a search for dark matter pair production in association with a Higgs boson decaying to a pair of bottom quarks, using data from 20.3 fb-1 of pp collisions at a center-of-mass energy of 8 TeV collected by the ATLAS detector at the LHC. The decay of the Higgs boson is reconstructed as a high-momentum bb system with either a pair of small-radius jets, or a single large-radius
This paper presents a measurement of the W boson production cross section and the W+/W− cross-section ratio, both in association with jets, in proton-proton collisions at s=8 TeV with the ATLAS experiment at the Large Hadron Collider. The measurement is performed in final states containing one electron and missing transverse momentum using data corresponding to an integrated luminosity of 20.2 fb−
“The Covid 19 pandemic took the meetings industry from top to bottom in one move”. These were the introducing words from the CEO of a large Swedish network of meetings firms, in their annual report for 2020. In the beginning of that year, one of the most challenging crises in the history of the meetings organizations emerged. Now, two years on the pandemic has changed the conditions for the entire
The term hybrid immunity is used to denote the immunological status of vaccinated individuals with a history of natural infection. Reports of new SARS-CoV-2 variants of concern motivate continuous rethought and renewal of COVID-19 vaccination programs. We used a naturalistic case-control study design to compare the effectiveness of the BNT162b2 mRNA vaccine to hybrid immunity 180 days post-vaccina
Purpose: To assess the association between cystatin C-derived estimates of kidney function and mortality and acute kidney injury (AKI) in sepsis. Materials and methods: Post-hoc analysis of sepsis patients in the FINNAKI-cohort (n = 802). Primary outcome was 90-day mortality. We measured plasma cystatin C and creatinine at intensive care unit (ICU) admission and estimated glomerular filtration rat
A generic search for resonances is performed with events containing a Z boson with transverse momentum greater than 100 GeV, decaying into e + e − or μ + μ −. The analysed data collected with the ATLAS detector in proton-proton collisions at a centre-of-mass energy of 13 TeV at the Large Hadron Collider correspond to an integrated luminosity of 139 fb −1. Two invariant mass distributions are exa
A search for pair production of scalar leptoquarks, each decaying into either an electron or a muon and a top quark, is presented. This is the first leptoquark search using ATLAS data to investigate top-philic cross-generational couplings that could provide explanations for recently observed anomalies in B meson decays. This analysis targets high leptoquark masses which cause the decay products of
The results of a search for direct pair production of top squarks and for dark matter in events with two opposite-charge leptons (electrons or muons), jets and missing transverse momentum are reported, using 139 fb−1 of integrated luminosity from proton-proton collisions at s = 13 TeV, collected by the ATLAS detector at the Large Hadron Collider during Run 2 (2015–2018). This search considers the
BACKGROUND: Engagement in activities meaningful to the individual may support the process of recovery in those with mental illness. Persons with psychiatric disabilities may reduce their engagement in meaningful activities to various degrees with possible fluctuations over time. We hypothesized that activity engagement can be altered when opportunities and support are offered at an individual and
Syftet med denna studie var att undersöka hur fitness influencers på plattformen Instagram använder sig av erfarenheter kring mental- och fysisk ohälsa för att skildra sig själva som autentiska individer. Dessa motgångar antogs leda till upprättandet av emotionella band med deras följare, och därmed ett stärkande av influencernas varumärkesidentiteter. Tidigare forskning visar att autenticitet spe
Along with the rapid development of investment and trade in the context of economic globalisation, a number of legal issues, risks and disputes related to the essential security exception have gradually emerged in the field of international investment. Although contracting states have consciously agreed on essential security exception regulations in the international investment system, the provisi
Disengagement is a phenomenon that exists to some degree in all levels of education. Socio-psychological in nature, it manifests in a wide array of behaviours, from inactivity to disruptive behaviour. This thesis is an explorative and dialectical study of the methods and strategies used to engage disengaged students, focusing on the digital language classroom. Using qualitative research methods,
There is a need for more efficient measures to ensure responsible migration in host countries. Sports are recognised as a key measure to promote integration. This thesis’s purpose is to increase the understanding of the impacts football clubs have on integration for youth girls with foreign backgrounds in Stockholm, Sweden. This is done by exploring social relations’ role in integration and examin

This thesis aims to look into how some social workers in Sweden view their work with youths having sex for compensation with regards to the feminist ideas that the law on buying sex expresses. Swedish studies have shown that most of the youths having sex for compensation started when they were 13-14 years old. Previous literature and studies state that youths having sex for compensation often have
