The over-riding aim of this thesis was to obtain a deeper understanding of the way patients with cardiac problems view both information related to their health and medical decisions and their role in decision-making processes. An important objective was to identify reasons why patients do not ask for or assimilate information or why they do not want or feel that they are able to influence medical

This work concerns two-dimensional numerical simulations of the flow and temperature fields inside smooth and ribbed bend (turn) parts of a U-duct with relevance for internal tip cooling of gas turbine blades. The ribs are placed internally on the outermost bend surface. The renormalization group (RNG) k-epsilon turbulence model was used to solve the momentum and energy equations inside the bend (

Popular Abstract in Swedish Studie av Två-Fotons processer vid låg Q2 med hjälp av VSAT kalorimetern i DELPHI experimentet Den här studien är baserad på data som har insamlats med hjälp av LEP (Large Electron-Positron) acceleratorn under dess andra tidsperioden LEP II (1996-2000) då strålenergin uppgick till 103-104 GeV. Under den perioden insamlades vid DELPHI (DEtector with Lepton, Photon and HThe study is based on data collected at the LEP II accelerator during the second period of the Large Electron-Positron collider operations (1996-2000). During that time the DELPHI (DEtector with Lepton, Photon and Hadron Identification) experiment collected about 90 Gb of data on tape corresponding to 687-691 pb-1 of luminosity. The data obtained by the VSAT (Very Small Angle Tagger) electromagne

Popular Abstract in Swedish Alla människor blir dagligen utsatta för olika typer av främmande organismer som kan förorsaka kroppen skada. Därför har vi utvecklat celler som har till uppgift att "döda" och avlägsna allt främmande som kommer in i kroppen, det så kallade immunförsvaret. Immunförsvaret består av ett komplicerat nätverk av celler och molekyler som tillsammans skyddar oss om vi utsätts This thesis deals with the interactions between superantigens and their receptors. Superantigens are proteins that are secreted by various bacteria, such as Staphylococcus aureus and Streptococcus pyogenes. Superantigens are able to cross-link T cells and antigen presenting cells by binding to the T cell receptor (TCR) and MHC class II. They bind as unprocessed antigens and activate up to 20 % of

Imaging of vapor-phase H2O2 concentrations is performed using photofragmentation LIF. An Nd:YAG-laser is used for photolysis and a dye laser for LIF on OH generated in the photolysis process. Detection limit is similar to 30 ppm. (C) 2009 Optical Society of America

Popular Abstract in Swedish Omkring hälften av alla kvinnor kommer någon gång efter 50 års ålder att drabbas av ett benbrott. Ett benbrott ger upphov till smärta, en risk för långvarig invaliditet och förtida död. Det är viktigt att försöka hitta dem som riskerar att drabbas, eftersom det möjliggör förebyggande behandling. Hur stor risken är att man drabbas av ett benbrott på äldre dagar beror fraApproximately half of all women will sustain a fracture after the age of 50. Fractures may cause long-term disability and excess mortality. Identifying individuals at high risk of sustaining a fracture is important in the development of primary and secondary prevention strategies. In this study, initiated to identify factors associated with a high risk of future fractures, 1 044 women, all 75 yea

Central to the sustainable production and consumption (SCP) agenda is the need for radical changes not only in the ways we produce but also in the ways we consume. The SCP agenda emerged within the understanding that it is not possible to reach the necessary reductions in environmental impact and resource consumption purely by technical solutions directed at improving the efficiency of production

Popular Abstract in Swedish Asymmetrisk syntes för framställning av optiskt rena substanser är av stort intresse, inte bara för forskningsändamål utan även för praktiska tillämpningar inom flera olika branscher. Dagligen stöter man på produkter som har sitt ursprung i asymmetrisk syntes; allt från dofter, smakämnen och livräddande läkemedel till nya praktiska plaster med skräddarsydda egenskaper. In this work, the synthesis and characterisation of new low-valence transition metal carbonyl clusters, and an investigation into their viability to act as catalysts/catalyst precursors in asymmetric synthesis, are described. Carbonyl clusters based on ruthenium and osmium have been tested as (pre)catalysts for asymmetric hydrogenation of alpha-unsaturated carboxylic acids, and cobalt carbonyl clu

Forskningsöversikten lyfter fram flera svåra och kontroversiella frågor t.ex. om kvalitet kan mätas, om formell utbildning behövs, personalens balansgång mellan den äldres integritet och ansvaret för den äldres välbefinnande.
