Climate change and atmospheric aerosols are a threat for human health and life. Reducing aerosol emissions would save human lives close to the aerosol source, but could lead to more death due to the implications of a warmer climate. Aerosol particles acting as cloud or ice nuclei can induce a change in cloud properties and thus indirectly induce a change in planetary albedo, which is considered th

The effect of the tetrapeptide des-arg -enterostatin (Val-Pro-Asp-Pro) on the growth of muang bean, Vigna rodiate, was studied. At a concentration of 0.2mM in the nutrient solution the peptide reduced the growth significantly. Possible mechanisms underlying the growth inhibition are discussed.

Popular Abstract in Swedish Atomer är de grundläggande byggstenarna för alla material runt omkring oss. Varje enskild atom består av ett tätt packat område i centrum, som kallas atomkärnan, omgivet av ett moln av elektroner. Atomkärnan innehåller neutroner och protoner, hopbundna av den starka kärnkraften. Vissa kombinationer av neutroner och protoner leder till bildandet av kärnor som är stabilaA series of experiments and developments, related to stable and radioactive isotopes, have been carried out. These studies have focused on measuring the low-lying excitations of spherical and deformed nuclei using electromagnetic (Coulomb) excitation and also on developments in detector technology for upcoming radioactive ion beams facilities. The low-lying excitations in the nuclei 107,109Sn and

Length and area regularization are commonplace for inverse problems today. It has however turned out to be much more difficult to incorporate a curvature prior. In this paper we propose several improvements to a recently proposed framework based on global optimization. We identify and solve an issue with extraneous arcs in the original formulation by introducing region consistency constraints. The

Popular Abstract in Swedish Bruket av slåtterängar som fodermarker har mycket gamla anor i Sverige. Slåtterängar karaktäriseras av att huvuddelen av de arter som växer här har inhemskt ursprung. De uppkom när människorna blev bofasta och klimatet så kallt att kreaturen behövde stallas under vintern (tidig Järnålder) och man därmed behövde vinterfoder till djuren. Idag är ängen en hotad biotop efteThe objectives of this thesis were to: 1) survey the vegetation in semi-natural meadows in south-central Sweden, 2) discern meadow vegetation changes in eight semi-permanent plots between studies performed in the 1960s and in 1990, 3) experimentally investigate the effects of variations in management intensity in one dry and one mesic meadow, 4) experimentally investigate the effects of different

Popular Abstract in Swedish Forskningen som presenteras i denna avhandling fokuserar på tillverkning av små strukturella enheter (komponenter) samt tillämpning av ny teknologi för att adressera viktiga medicinska forskningsfrågeställningar. Framtagande av teknologi som använder sig av komponenter som är tusentals gånger mindre än bredden på ett hår är svårt men möjligt. Denna avhandling fokuserar This thesis focuses on the study of thin-film sensor technologies, novel microfabrication technologies, and thin-film technology in general. The work discusses electrochemical sensors and mechanical sensor technologies as well as fabrication strategies for them. Also included are mechano-chemical studies of the vancomycin DAla (Bacteria membrane analogue motif ) binding reaction in different chemica

Popular Abstract in Swedish I Sverige produceras en stor del av elektriciteten i kärnkraftverk och som restprodukt får man ett mycket farligt radioaktivt avfall som måste isoleras från människor i hundratusentals till miljoner år. Svensk Kärnbränslehantering AB (SKB) har i uppdrag att ta hand om detta avfall och har utvecklat metoden KBS-3. I denna placeras det använda kärnbränslet i en kopparkapsBentonite is planned for use as a buffer material in high-level radioactive waste repositories, where safety assessment is performed for very long periods (100-1000 ka). This thesis focuses on the swelling of smectites in liquid water, and analysis of bentonite from field experiments at Äspö Hard Rock Laboratory, Sweden. Four field experiments were analyzed (Alternative Buffer Material experiment,

A linear distinguishing attack on the for stream cipher Scream is proposed. The attack uses approximately 2100 output words and has complexity of a similar size
