We report on a dedicated effort to identify and study metal-poor stars strongly enhanced in r-process elements ([r/Fe]>1 dex; hereafter r-IIstars), the Hamburg/ESO R-process Enhanced Star survey (HERES).Moderate-resolution (∼2 Å) follow-up spectroscopy has been obtained for metal-poor giant candidates selected from the Hamburg/ESO objective-prism survey (HES) as well as the HK survey to identify s
Popular Abstract in Swedish Mycken möda har under de senaste årtiondena lagts ner på forskning om försurande utsläpp och dess skadliga effekter på skogar, vattendrag och människor. Kritiska belastningsgränser, i folkmun kallat "vad naturen tål", har tagits fram och använts i europeiska förhandlingar om utsläppbegränsningar. För skogsekosystem baseras de kritiska belastningsgränserna för försurandeAcidification caused by emissions of Nitrogen and Sulphur and associated adverse effects on forest ecosystems has been an issue on the political agenda for decades. Temporal aspects of soil acidification and/or recovery can be investigated using the soil chemistry model SAFE, a dynamic version of the steady-state model PROFILE used in critical loads assessment on the national level, e.g. for Swede
The impact of cytogenetic findings in AML was analyzed in the large population-based Swedish AML registry. Karyotypic patterns differed by age: t(8;21), inv(16) and t(11q23) were more common in younger patients, whereas loss of 5q, 7q and 17p, monosomal karyotype (MK) and complex karyotype (CK) were more common in older patients. Patients with ≥5 chromosome abnormalities had worse overall survival
This article deals with specific words in an old lullaby, a rhyme recorded in Scania, Sweden in the 19th century. The lullaby has also been recorded in Denmark and Norway. The aim of the article is to place the specific lullaby in a historical context and demonstrate how to use a comparative method when analysing mythological phenomena. The author’s thesis is that only a word or two in a simple lu
Popular Abstract in Swedish Bröstcancer är den vanligaste dödsorsaken bland cancersjuka kvinnor. Därför rekommenderas regelbundna mammografiska hälsokontroller för tidig diagnostik och snar behandling för att förbättra prognosen. I Sverige rekommenderas kontroller för kvinnor mellan 40-74 år. Mammografiska hälsokontroller medför dock även risker, såsom till exempel behov av kompletterande bröstundOne side-effect of breast cancer (BC) screening is a false-positive mammogram among healthy women. That is, finding(s) on a screening mammogram that lead to additional breast examinations but where the woman is eventually considered free from BC. There is evidence of short-term psychosocial consequences of false-positive BC screening. Regarding long-term consequences, research findings are inconsi
Proteinase 3 (PR3) is a neutrophil serine protease stored in the azurophil granules of the promyelocyte and its successors. The protease has been identified as an autoantigen for anti-neutrophil cytoplasmic autoantibodies (ANCA) occurring in patients with Wegener's granulomatosis. To characterize the biosynthesis and processing of human PR3 in a transgenic cellular model, cDNA encoding human pre-p
Background. The conventional treatment for poststernotomy mediastinitis usually involves surgical revision, closed irrigation, or reconstruction with omentum or pectoral muscle flaps. Recently, vacuum-assisted closure has been successfully used in poststernotomy mediastinitis. The aim of the present study was to compare the clinical outcome and survival in 101 patients undergoing vacuum-assisted c
Car developers use digital human modeling tools to analyze and visualize car interiors in relation to human characteristics before the vehicles are actually constructed. Developers, reviewers and users of human simulation tools often claim that such tools can reduce development time and costs. In car industry companies today, human simulation tools are used by a single or a few experts in an infor
This dissertation deals with analog techniques at both the architecture and circuit design levels for designing power efficient linear radio-frequency (RF) transmitters. The use of nonlinear analog integrated circuits to implement certain critical signal processing functions for the multiplicative feedback and LINC techniques is investigated with the aim of improving the system performance in term
Finding life on a planet other than the Earth would easily be one of the greatest discoveries of all time, particularly so if it is found outside our Solar System. To do so, we must understand the conditions required for life to emerge and develop. Whilst an enormous amount of research has gone into understanding the requirements for life on Earth to have spontaneously arisen and then evolved, muc
Synopsis In methanol solutions of Zeise's salt, the parent complex [PtCl3(C2H4)]- as well as its solvolysis product, trans-[PtCl2(C2H4)(MeOH)], exchange rapidly with free ethene. The olefin exchange process, which is largely entropy controlled, involves the substitution labile site trans to the coordinated ethene. Abstract Complex equilibria in methanol/chloroform/dichloromethane solutions c
Background: The impact of obesity on patient-reported outcome (PRO) after total knee arthroplasty (TKA) surgery has demonstrated varying results. We evaluated knee pain, Activity in Daily Life function (ADL), and satisfaction after TKA surgery in patients with and without prior bariatric surgery (BS). Methods: Scandinavian Obesity Surgery Registry (SOReg) and the Swedish Knee Arthroplasty Register
Salinity Gradient Power - Reverse Electrodialysis (SGP-RED) is a promising membrane-based technology to harvest the energy of mixing from solutions of different ionic concentration. Unfortunately, currently available commercial ion exchange membranes – being not specifically designed for RED – are far from satisfying the requirements of this operation, especially when operated with hyper-concentra
INTRODUCTION: Thorough treatment planning is essential for a good clinical outcome in orthognathic treatment. The planning is often digital. Both 2-dimensional (2D) and 3-dimensional (3D) software options are available. The aim of this randomized 2-arm parallel double-blinded active-controlled clinical trial was to compare the outcomes of computer-based 2D and 3D planning techniques according to p
Elastic fibers containing elastin play an important role in tendon functionality, but the knowledge on presence and function of elastin during tendon healing is limited. The aim of this study was to investigate elastin content and distribution in intact and healing Achilles tendons and to understand how elastin influence the viscoelastic properties of tendons. The right Achilles tendon was complet
Wood growth constitutes the main process for long‐term atmospheric carbon sequestration in vegetation. However, our understanding of the process of wood growth and its response to environmental drivers is limited. Current dynamic global vegetation models (DGVMs) are mainly photosynthesis‐driven and thus do not explicitly include a direct environmental effect on tree growth. However, physiological
This thesis is concerned with modeling of the cracking process in reinforced concrete due to imposed deformations. Cracking is investigated both at early ages, during hydration, and at mature age when the final properties of the concrete are reached. One of the most important material characteristics of the concrete at early ages, the Young’s modulus is determined by means of a dynamic method call
There is a thin line between life and death. In the medical domain, risk management can be an instrument that helps the development organisations to develop safer medical devices. A medical device that fails can bring harm to both patients and medical staff. The medical device domain is a complex field where there are several characteristics contributing to the complexity. Many of the functions pe
