In this study, we modeled the aerosol particle formation along air mass trajectories arriving at the remote Arctic research stations Gruvebadet (67 m a.s.l.) and Zeppelin (474 m a.s.l.), Ny-Ålesund, during May 2018. The aim of this study was to improve our understanding of processes governing secondary aerosol formation in remote Arctic marine environments. We run the Lagrangian chemistry transpor

In recent years, FLASH irradiation has attracted significant interest in radiation research. Studies have shown that irradiation at ultra-high dose rates (FLASH) reduces the severity of toxicities in normal tissues compared to irradiation at conventional dose rates (CONV), as currently used in clinical practice. Most pre-clinical work is currently carried out using charged particle beams and the b

The use of celestial or geomagnetic orientation cues can lead migratory birds along different migration routes during the migratory journeys, e.g. great circle routes (approximate), geographic or magnetic loxodromes. Orientation cage experiments have indicated that migrating birds are capable of detecting magnetic compass information at high northern latitudes even at very steep angles of inclinat

This book is a contribution to the discussion about religion in contemporary Western society, characterized by the privatization of religion. The concept religion is not easily operational and does not carry meaning or implications that remain valid or consistent over time. It must be re-substantiated in order to remain descriptive and operational. This book’s ambition is to explore a means of re-

Popular Abstract in Swedish Stroke är ett akut neurologiskt tillstånd och den främsta anledningen till funktionsnedsättning hos vuxna. Det finns ingen behandling för effektiv återhämtning. Den vanligaste formen av stroke orsakas av att mellersta storhjärnsartären blockeras vilket gör att man förlorar hjärnceller, till exempel neuroner. Neurala stamceller (NSCs) skulle kunna användas för att återstStroke is an acute neurological condition and the leading cause of disability in adult humans. Treatments for efficient recovery are not available. The most common form of stroke results from the occlusion of the middle cerebral artery, which causes loss of brain parenchyma and many types of neurons as well as astrocytes and oligodendrocytes. Neural stem cells (NSCs) could potentially be used to d

The mixed-valence triiron complexes [Fe3(CO)7-x (PPh3) x (μ-edt)2] (x = 0-2; edt = SCH2CH2S) and [Fe3(CO)5(κ(2)-diphosphine)(μ-edt)2] (diphosphine = dppv, dppe, dppb, dppn) have been prepared and structurally characterized. All adopt an anti arrangement of the dithiolate bridges, and PPh3 substitution occurs at the apical positions of the outer iron atoms, while the diphosphine complexes exist onl

This thesis, consisting of six papers, concerns methods for probabilistic analysis of engineering structures. The work comprises evaluations of available methods, developments of new and improved methods, and applications of probabilistic analysis to engineering structures. Comparative calculations using methods representing different strategies for stochastic finite element analysis were carried

Popular Abstract in Swedish Kambrium är ett tidsavsnitt av jordens historia som spänner från ca 542 till 488 miljoner år sedan. Under denna tid utvecklades livet, främst djur, i en rasande takt genom något som brukar kallas den kambriska explosionen, en ekologisk förändring utan dess like. Bland de nya livsformer som fick de kambriska haven att koka av liv märks skalbärande djur som små armfotingaThis thesis is based on studies of Cambrian successions in Sweden, with particular focus on the middle Cambrian biostratigraphy and its correlative relationship to the proposed global agnostoid zonation. The investigated material, mainly trilobites, was collected from both outcrops and drill cores from five provinces in Sweden: Skåne (Scania), Öland, Västergötland, Jämtland and Lapland. The Almba

Acquired clonal chromosome aberrations, closely associated with leukemogenesis, are found in many hematologic malignancies. Although the balanced rearrangements, such as translocations and inversions, are the ones most commonly thought of in the context of leukemias, gains of chromosomes ? e.g.., trisomies ? are also frequent. Little is known about the biologic outcome, the pathogenetic significan

Popular Abstract in Swedish Tunnelbygget genom Hallandsåsen har utvecklats på ett sådant sätt och fått sådana konsekvenser, att frågan hur projektet skall förstås och förklaras är viktig. Vill man studera vilka mekanismer i samhället som kan förhindra projektets förlopp eller dess konsekvenser, bör man först förstå projektet. Matthias Baiers bok handlar om hur man med normer kan förstå och beskrivIn 1992 Swedens biggest tunnelproject begun. Two 8.5 km tunnels should cross a big ridge in southern Sweden which was seen as an obstacle to a fast and efficient railway line connecting Oslo and Gothenburg with Malmö and Copenhagen. However, the project had to stop in 1997 due to environmental damages. With only a third of the tunnel accomplished, the project was also much delayed and had a heavy

Ultra-fast substitution of chloride for bromide, iodide, azide and thiocyanate trans to ethene in Zeise's anion, [PtCl3(C2H4)](-), 1, has been investigated in methanol solvent by use of cryo temperature diode array stopped-flow spectrophotometry. Reactions follow the usual two-term rate law for square-planar substitutions, k(obs)=k(1)+k(2)[Y] (where k(1)=k(MeOH) [MeOH]), with k(1)=118+/-10 s(-1) a

Optical region spectra for a number of upper main sequence chemically peculiar (CP) stars have been observed to study singly and doubly ionized praseodymium and neodymium lines. In order to improve existing atomic data of these elements, laboratory measurements have been carried out with the Lund VUV Fourier Transform Spectrometer (FTS). From these measurements wavelengths and hyperfine structure

Popular Abstract in Swedish Sjukdomsuppfattningar. Värderingar och attityder hos patienter och medicine studerande. Utvecklingen av den biomedicinska kunskapen och de demografiska förändringarna under 1900-talet har inneburit en ökning av såväl behov av som efterfrågan på hälso- och sjukvård. Illabefinnande utan påvisbara sjukdomstecken och rädsla för sjukdom ligger ofta bakom vårdsökande. OfficieDuring the 20th century, the development of biomedical knowledge and the demographical changes have increased the needs and demands for health care in industrialised countries. Illness without evidence of disease and fear of disease are often the reasons for seeking medical care. Primary care is the official foundation of the Swedish health care system but priorities are vague and frequently chang

Popular Abstract in Swedish Den moderna genetiken tar sin början kring sekelskiftet 1900 då de mendelska lagarna återupptäcktes. Den tidiga utvecklingen skedde i många länder i nära anslutning till den praktiska växtförädlingen, så även i Sverige där det redan fanns en framgångsrik växtförädling genom Sveriges utsädesförenings verksamhet i Svalöf. Här introducerade botanisten Herman Nilsson-Ehle mIn the first part of the 20th century genetics developed into an important research field. The aim of this study is to follow and analyse the transformation of genetics from its origin within an agricultural context to an academic discipline in Sweden (ca. 1900-1960). Mendelism was introduced as a methodology in plant breeding at the plant breeding station in Svalöf during the first decade of the

Quantitative fluorescence in situ hybridization (FISH) and the combination of FISH with microautoradiography (MAR) were used in order to study the long-term population dynamics (2.5 years) and the in situ physiology in two parallel activated sludge pilot systems with enhanced biological phosphorus removal (EBPR). The two systems received the same influent wastewater, but were differently operated

Popular Abstract in Swedish I de hänvisningar som används i ett stort antal sociala projekt för att målet skall uppnås hittas rättighet och rättvisa som centrala diskursiva enheter i en återkommande använd tankemodell. I flera av dessa projekt blir resultatet, gång efter annan, utebliven framgång. Men den samma rätta tankemodellen förblir en självklar utgångspunkt. De upprepade krigen mot fattigdoIn the references invoked by a large number of social projects to achieve their goals, one can find rights and justice as central discursive units in a frequently recurring thought model. In several of these projects the result, time after time, is lack of success. But the same right thought model continues to be taken for granted as a point of departure. The repeated wars on poverty in the USA ex

Pharmacokinetic (PK) and pharmacodynamic (PD) properties for the selection of resistant pneumococci were studied by using three strains of the same serotype (6B) for mixed-culture infection in time-kill experiments in vitro and in three different animal models, the mouse peritonitis, the mouse thigh, and the rabbit tissue cage models. Treatment regimens with penicillin were designed to give a wide

Quick clay has a major impact on landslide risk and it is therefore of considerable interest to map its presence and extent. In Sweden, quick clay has been involved in most landslides in soft clay with serious consequences. The predominant method for detection of quick clay in Sweden has been to take undisturbed samples and to perform fall-cone tests on the clay in its undisturbed and remoulded st

Popular Abstract in Swedish Kultursemiotiken studerar möten mellan kulturer. Begreppen Kultur, Extra-kultur och Icke-kultur utvecklades av Tartuskolan under 1970-talet, och användes i deras studier av den ryska kulturen och dess relation till Västeuropa. Särskild vikt lades vid Peter den Stores försök att göra Ryssland mer likt Väst. Målet med denna avhandling i kultursemiotik är att vidareutvecklCultural semiotics studies encounters between cultures. Notions such as Culture, Extra-culture and Non-culture were developed in the 1970s by the Tartu school and were used in their studies of Russian culture and its relation to Western Europe, with special focus on Peter the Great's attempt to Westernize Russia in the eighteenth century. The aim of this dissertation in cultural semiotics is to fu

The interest in diffusion imaging with nuclear magnetic resonance techniques has increased during the last few years. The main reason is the possibility of early diagnosis of acute ischaemic stroke, at a time when conventional MR techniques and computerised tomography fail. The purpose of this study was to develop and evaluate methods for the measurement of water self-diffusion in vivo usin
