The GALAH Survey: Chemical Clocks

We present the first large-scale study that demonstrates how ages can be determined for large samples of stars through Galactic chemical evolution. Previous studies found that the elemental abundances of a star correlate directly with its age and metallicity. Using this knowledge, we derive ages for 214 577 stars in GALAH DR3 using only overall metallicities and chemical abundances. Stellar ages a

Allianser och polarisering bland hemtjänstpersonal : en (o)önskad konsekvens av valfrihet och konkurrens inom äldreomsorgen?

Syftet med denna studie är att belysa hur kommunal och privat hemtjänstpersonal resonerar om varandras verksamheter i utförandet av biståndsbedömda insatser inom äldreomsorgen. Studien är baserad på 28 öppna, semistrukturerade intervjuer med hemtjänstpersonal i kommuner som infört kundval.Resultatet visar att hemtjänstpersonalen, verksamhetsformerna emellan, utvecklar både allianser och polariseri

Roles of alcohol use disorder and resilience in risk of suicide attempt in men : A Swedish population-based cohort

Introduction: Alcohol use disorder (AUD) has been identified as a strong risk factor for suicide attempt. However, few studies have considered protective factors that may moderate this association, such as resilience. Methods: We used longitudinal nationwide Swedish data of 903,333 males born 1960–1980 and 48,285 males born 1949–1951. We performed Cox proportional hazards models to test the role o

Long term oncologic and reproductive outcomes after robot-assisted radical trachelectomy for early-stage cervical cancer. An international multicenter study

Objectives: Long term outcomes following fertility sparing robot-assisted radical trachelectomy (RRT). Methods: A retrospective study of consecutive women selected for RRT between 2007 and 2019 at five referral centres. Generally used selection criteria for fertility-sparing surgery were applied. Oncologic, reproductive and long-term clinical data were analysed. Results: Of the 166 included women,

An old, metal-rich accreted stellar component in the Milky Way stellar disk

We study the possibility that the Milky Ways' cool stellar disk includes mergers with ancient stars. Galaxies are understood to form in a hierarchical manner, where smaller (proto-)galaxies merge into larger ones. Stars in galaxies, like the Milky Way, contain in their motions and elemental abundance tracers of past events and can be used to disentangle merger remnants from stars that formed in th
