- We discuss strategies for the detection of additional examples of highly r-process-enhanced, ultra-metal-poor stars, such as the two presently known examples of the class, CS~22892-052, and the newly discovered CS~31082-001. We expect that a quick, modera

- • The aim of this study was to describe changes in the life situation of patients with an implantable cardioverter defibrillator over a period of 1 year. A sample of 56 consecutive patients took part in the study.• Life situation was measured through uncertainty in illness, satisfaction, and fear of the life situation. Descriptive statistics were used to present results, and analytical statistics were used to map out changes over time.• Overall uncertainty showed a decrease over time. A statistically significant difference was found within the domain uncertainty related to information (P < 0.001).• Satisfaction increased within the domains health-functioning, socio-economic, psychological–spiritual, and family.• The ability to act within the domain health-functioning showed a statistical significance (P < 0.05).• The domain life changes within fear in the life situation decreased and showed a statistical significance (P < 0.05).• The overall life situation showed increased satisfaction as well as lower uncertainty and fear in the life situation.• The research indicates that patients need more information about changes in the life situation after the implantable cardioverter defibrillator-implantation. The study encourages more humanistic, holistic research about patients’ life situations as well as more education in teaching skills for health care personnel.

Subgiants as probes of galactic chemical evolution
- 2004
-
Ingår i: Astronomy & Astrophysics. - 0004-6361. ; 425:1, s. 187-206
-
Tidskriftsartikel (refereegranskat)abstract
- Chemical abundances for 23 candidate subgiant stars have been derived with the aim at exploring their usefulness for studies of galactic chemical evolution. High-resolution spectra from ESO CAT-CES and NOT-SOFIN covered 16 different spectral regions in the visible part of the spectrum. Some 200 different atomic and molecular spectral lines have been used for abundance analysis of approximately 30 elemental species. The wings of strong, pressure-broadened metal lines were used for determination of stellar surface gravities, which have been compared with gravities derived from Hipparcos parallaxes and isochronic masses. Stellar space velocities have been derived from Hipparcos and Simbad data, and ages and masses were derived with recent isochrones. Only 12 of the stars turned out to be subgiants, i.e. on the "horizontal" part of the evolutionary track between the dwarf- and the giant stages. The abundances derived for the subgiants correspond closely to those of dwarf stars. With the possible exceptions of lithium and carbon we find that subgiant stars show no "chemical" traces of post-main-sequence evolution and that they are therefore very useful targets for studies of galactic chemical evolution.

Life situation related to the ICD implantation : self-reported uncertainty and satisfaction in Swedish and US samples
- 2002
-
Ingår i: European Journal of Cardiovascular Nursing. - Amsterdam : Elsevier. - 1474-5151 .- 1873-1953. ; 1:4, s. 243-251

Tidskriftsartikel (refereegranskat)abstract
- The aim of the study was to describe changes in the life situation related to the ICD implantation of Swedish and US samples with regard to uncertainty and satisfaction. The life situation was measured by reference to the uncertainty caused by the condition and satisfaction with the life situation. Inferential statistics were used to analyse changes within and between the Swedish and US samples. Uncertainty showed a statistically significant difference between the Swedish and US samples before as well as after the ICD implantation. A higher level of uncertainty was indicated for the US sample prior to the ICD implantation and for the Swedish sample following the implantation. In the Swedish sample, satisfaction with life showed a statistically significant difference within the socio-economic domain, indicating a higher degree of satisfaction 3 months after implantation. Satisfaction within the domains of health and functioning, socio-economics and psychological-spiritual showed a statistically significant difference between the Swedish and US samples both before and after ICD implantation, indicating a higher degree of satisfaction in the US sample. The previous study shows that the ICD-patient's life situation is changed after the implantation and that it is necessary to provide the patient with information and education based on their own preconditions. The fact that US sample was investigated at a later stage after ICD implantation than the Swedish sample may have influenced the results of the study.
