The Gaia-ESO Survey : Inhibited extra mixing in two giants of the open cluster Trumpler 20?

We report the discovery of two Li-rich giants, with A(Li) ~ 1.50, in an analysis of a sample of 40 giants of the open cluster Trumpler 20 (with turnoff mass ~1.8 M⊙). The cluster was observed in the context of the Gaia-ESO Survey. Methods. The atmospheric parameters and Li abundances were derived using high-resolution UVES spectra. The Li abundances were corrected for nonlocal thermodynamical equi

Criminality, incarceration and control in Nordic Island societies: The Faroe Islands, The Åland Islands, Iceland and Greenland.

There are large differences between the four Nordic island societies in culture, and also on how they have achieved autonomy/independence and to what extent this is implemented. They have more characteristics in common than they have with the remaining Nordic countries: Small populations that live in secluded island societies, geographically isolated from other countries; rough living conditions a

The Gaia -ESO Survey : Separating disk chemical substructures with cluster models∗: Evidence of a separate evolution in the metal-poor thin disk

Context. Recent spectroscopic surveys have begun to explore the Galactic disk system on the basis of large data samples, with spatial distributions sampling regions well outside the solar neighborhood. In this way, they provide valuable information for testing spatial and temporal variations of disk structure kinematics and chemical evolution. Aims. The main purposes of this study are to demonstra

THE Gaia-ESO Survey : Metal-rich bananas in the bulge

We analyze the kinematics of ∼2000 giant stars in the direction of the Galactic bulge, extracted from the Gaia-ESO survey in the region -10° ≲ l≲ 10° and -11° ≲ b ≲ -3°. We find distinct kinematic trends in the metal-rich ([M H] > 0) and metal-poor ([M H]

The origin and evolution of r - and s -process elements in the Milky Way stellar disk

Context. Elements heavier than iron are produced through neutron-capture processes in the different phases of stellar evolution. Asymptotic giant branch (AGB) stars are believed to be mainly responsible for elements that form through the slow neutron-capture process, while the elements created in the rapid neutron-capture process have production sites that are less understood. Knowledge of abundan

The Gaia -ESO Survey : Sodium and aluminium abundances in giants and dwarfs: Implications for stellar and Galactic chemical evolution

Context. Stellar evolution models predict that internal mixing should cause some sodium overabundance at the surface of red giants more massive than ~1.5-2.0 M⊙. The surface aluminium abundance should not be affected. Nevertheless, observational results disagree about the presence and/or the degree of Na and Al overabundances. In addition, Galactic chemical evolution models adopting different stel

The Gaia-ESO Survey: A lithium-rotation connection at 5 Myr?

Context. The evolution of lithium abundance in cool dwarfs provides a unique probe of nonstandard processes in stellar evolution. Aims. We investigate the lithium content of young low-mass stars in the 5 Myr old, star forming region NGC 2264 and its relationship with rotation. Methods. We combine lithium equivalent width measurements (EW(Li)) from the Gaia-ESO Survey with the determination of rota

Survival of habitable planets in unstable planetary systems

Many observed giant planets lie on eccentric orbits. Such orbits could be the result of strong scatterings with other giant planets. The same dynamical instability that produces giant planet scatterings can also alter the orbits of terrestrial planets. For example, a habitable rocky planet in the system can be ejected or transported to an orbit outside the habitable zone. Therefore, there is a lin

Människan som biologiskt reservmaterial : Ninni Holmqvists dystopi Enhet

I den dystopiska skildringen Enhet (2006) gestaltar Ninni Holmqvist ett alternativt svenskt samhälle där människor som inte är samhällsnyttiga används som biologiskt reservmaterial för att bota sjukdomar hos andra, behövda människor. Samhället har blivit totalitärt, människor bedöms efter produktivitet och organdonation har blivit ett tvång för vissa grupper. I den här artikeln diskuterar jag hur

Socioeconomic inequalities in knee pain, knee osteoarthritis, and health-related quality of life : a population-based cohort study in southern Sweden

Objectives: To determine socioeconomic inequalities in frequent knee pain (FKP), knee osteoarthritis (OA), and associated health-related quality of life (HRQoL) in Sweden. Method: In 2007 a postal questionnaire about knee pain was sent to a random sample of 10 000 residents of Malmö, Sweden (7402 individuals responded). Subjects reporting pain with duration ≥ 4 weeks in one or both knees in the pa

Occupational balance in health professionals in Sweden

Background: Health care employees are often women, a group that has high degrees of sick leave and perhaps problems attaining occupational balance. However, people think differently about their everyday activities and it is therefore important to take their perceptions into account but occupational balance has not yet been measured in health professionals. The aim was to describe occupational bala

Haemophilia treatment in 2030

Introduction: Looking into the future is difficult and sometimes hazardous. A reliable look into haemophilia treatment in 2030 should be based on history and contemporary progress as well as dilemmas. Today, the issue of inhibitors overshadows the entire haemophilia community together with lack of treatment for large parts of the world's persons with haemophilia. Aims: The aim of this paper was to

Low-grade inflammation, oxidative stress and risk of invasive post-menopausal breast cancer - A nested case-control study from the Malmö diet and cancer cohort

Objective: Although cancer promotes inflammation, the role of inflammation in tumor-genesis is less well established. The aim was to examine if low-grade inflammation is related to post-menopausal breast cancer risk, and if obesity modifies this association. Methods; In the Malmo Diet and Cancer cohort, a nested case-control study was defined among 8,513 women free of cancer and aged 55.73 years a

Metabolic profiling of systemic lupus erythematosus and comparison with primary Sjögren's syndrome and systemic sclerosis

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease which can affect most organ systems including skin, joints and the kidney. Clinically, SLE is a heterogeneous disease and shares features of several other rheumatic diseases, in particular primary Sjögrens syndrome (pSS) and systemic sclerosis (SSc), why it is difficult to diagnose The pathogenesis of SLE is not comple

Hydrogen bonds, hydrophobicity forces and the character of the collapse transition

We study the thermodynamic behavior of a model protein with 54 amino acidsthat is designed to form a three-helix bundle in its native state. The model contains three types of amino acids and five to six atoms per amino acid, and has the Ramachandran torsion angles as its only degrees of freedom.The force field is based on hydrogen bonds and effective hydrophobicity forces. We study how the charact
