This paper presents the light-scattering properties of atmospheric aerosol particles measured over the past decade at 28 ACTRIS observatories, which are located mainly in Europe. The data include particle light scattering (σsp) and hemispheric backscattering (σbsp) coefficients, scattering Ångström exponent (SAE), backscatter fraction (BF) and asymmetry parameter (g). An increasing gradient of σsp
Background: Child marriage is being increasingly recognized globally as a fundamental violation of human rights. Child marriages occur globally in varying degrees across countries and regions. South Asia alone accounted for almost half of the total number of child marriages that have occurred globally. Early marriage can lead to serious ramifications such as school drop-out, early pregnancy, mater
Background: Alkaline enzymes are stable biocatalysts with potential applications in industrial technologies that offer high quality products. Objective: The growing demand for alkaline enzymes in industry has enhanced the search for microorganisms that produce these enzymes. Methods: Eighteen bacterial isolates from Lake Bogoria, Kenya, were screened for alkaline proteases, pectinases and amylases
Popular Abstract in Swedish Däggdjurens mag-tarmkanal genomgår dramatiska strukturella och funktionella förändringar under di-perioden för att anpassa individen för den fasta föda som kommer att bli den huvudsakliga näringskällan efter avvänjningen från modersmjölken. Dessa förändringar följer en ?biologiska klocka? och är således huvudsakligen genetiskt styrda. Däremot kan yttre och inre stimuli The timing of the postnatal development of the gastrointestinal (GI) tract in mammals is influenced by dietary and hormonal factors. It was hypothesized that accelerated GI cell turnover during maturation would result in a precoucios conversion to more mature digestive functions. Thus, it was investigated if red kidney bean lectin, phytohaemagglutinin (PHA) - a potent gut mitogen in adult rats - c
Popular Abstract in Swedish Luften omkring oss består inte bara av gaser. I den finns det mängder av små partiklar. De partiklar som står i fokus i den här avhandlingen är mindre än 10 μm, vilket endast är en femtedel av ett hårstrås diameter. Dessa partiklar är tillräckligt små för att kunna förflyttas långa sträckor i atmosfären och har dessutom visat sig påverka människors hälsa negativt. Man hAerosol particles are found in the whole troposphere. Research regarding these particles has gained increased attention because of the effect the particles have on both health and climate. In the atmosphere, aerosol particles scatter incoming solar radiation and this has a cooling effect on the Earth’s climate. But there are particles, especially those containing soot, which can absorb sun light a
Popular Abstract in Swedish Hjärt-kärlsjukdom är den vanligaste dödsorsaken i västvärlden. Till gruppen hjärt-kärlsjukdom räknas t.ex. hjärtinfarkt, åderförkalkning, högt blodtryck, kärlkramp och hjärtsvikt. Gemensamt för dessa sjukdomar är att blodkärlens egenskaper förändras. Blodkärlen drar lättare ihop sig vilket försämrar blodflödet och därmed sjukdomstillståndet. En orsak till förändringarnaAngiotensin II (Ang II) and endothelin-1 (ET-1) induce strong vasoconstriction via activation of receptors on vascular smooth muscle cells. In this thesis, the contractile Ang II and endothelin receptors were examined in endothelium-denuded human coronary arteries and in bypass grafts (the left internal mammary artery and the saphenous vein), with focus on receptor alterations in cardiovascular di
Popular Abstract in Swedish I det här arbetet har vattenlösningar av cellulosabaserade polymerer studerats. En polymer är en lång molekyl som består av många sammanlänkande repeterande enheter. Längs den vattenlösliga polymerryggraden har korta hydrofoba (vattenskyende) kedjor ympats, vilket resulterar i så kallade ympsampolymerer. I vattenlösning bildas ett polymernätverk genom att de hydrofoba gThe properties of hydrophobically modified cellulose derivatives in aqueous mixtures with various other molecules have been investigated. Mixtures of a hydrophobically modified polymer and alkali-sensitive, degradable surfactants gave rise to time-dependent viscosities. With time, the viscosity decreased continuously or went through a maximum, depending on the initial surfactant concentration. Th
Background: Cyclin D1 is a well-characterised cell cycle regulator with established oncogenic capabilities. Despite these properties, studies report contrasting links to tumour aggressiveness. It has previously been shown that silencing cyclin D1 increases the migratory capacity of MDA-MB-231 breast cancer cells with concomitant increase in 'inhibitor of differentiation 1' (ID1) gene expression. I
In this study we compared plasma contents of long-chain polyunsaturated fatty acids (LC-PUFAs) and trans fatty acids in triglycerides (TG), phospholipids (PL) and cholesterolesters (CE) in young children fed milk diets containing different amounts of linoleic (LA) and alpha-linolenic acid (ALA). Because the diets differed in vitamin A and E content, plasma concentrations of vitamin A and E were al
Popular Abstract in Swedish Avhandlingen "Decolonizing the Viking Age", i två volymer, argumenterar för att den skandinaviska vikingatiden kan ses som en teoretisk konstruktion som i allt väsentligt utarbetades under det sena 1800-talet. Detta tankesystem har därefter i allt väsentligt reproducerats till våra dagar. Konstruktionen av vikingatiden påverkades kraftigt av nationalism och evolutionsteDecolonizing the Viking Age 1 argues that the Scandinavian “Viking Age” can be seen as a system of knowledge constructed in the late 19th century and in its basic structures maintained up to the present day. This system of knowledge was heavily influenced by the nationalistic and evolutionary ideas of its time of making and may be described as a colonialism of the past. The book follows the making
Popular Abstract in Swedish Parallellt med att kommunerna under 1990-talet fick ett utvidgat ansvar för t.ex. vården av och omsorgen om äldre och funktionshindrade gavs de större frihet att lokalt bestämma över sina organisationsformer. Omständigheterna ledde till ett starkt kommunalt reformtryck, inte minst genom de reformförslag som på olika sätt och i varierande grad utmanade den traditionella The 1990s was a period characterized by a strong pressure for reform in the Swedish municipalities. The care manager reform, i.e. the initiation of a position within the administration - the care manager - whose work tasks are concentrated around needs-assessment practices only, was one of many reform proposals. Within a fairly short time span a great number of municipalities decided to implement

A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for skeletal metastases is based on data from 16 randomized trials. Moreov
Volatiles from Ips duplicatus male hindgut extracts and aeration samples of spruce logs colonized by the virgin males were analyzed by coupled gas chromatography-mass spectrometry (GC-MS), coupled gas chromatography-electroantennographic detection (GC-EAD), and field trapping bioassays in Inner Mongolia, China. GC-MS analyses showed that males from nuptial chambers (for reproduction) produced hind
The object of the study is to discuss how methods for increase interaction with communities can contribute to find ways for building relationships between local journalists and publics. Also, the study aims to display how trust can contribute to strategies for social sustainability of local journalism. Exploring new ways of studying communication and interactions in media and journalism is of high interest considering that we live in a constantly transforming media landscape. To build sustainable journalism and media organizations requires a holistic approach of the development involving audience, news producers and other stakeholders.This panel originates from studies applying action research o
Little is known about the demographic/life-style/physiological determinants explaining the variation of serum perfluoroalkyl acid (PFAA) concentrations in children. We identified significant determinants in children and investigated the influence of low-level PFAA-contaminated drinking water (DW) (<10 ng L-1 of single PFAAs) on serum concentrations. Four perfluorosulfonic acids (PFSAs) and 11 perf
BACKGROUND: During the therapeutic videofluoroscopic examination of swallowing, gradation of bolus volume, texture, and viscosity can be implemented to determine the optimal bolus characteristics in that particular patient. When a thickened liquid is given to a dysphagic patient it is served at room temperature. However, in these patients with a delayed oral and/or pharyngeal stage of swallow, the
This thesis focuses on bioactive lipids as (1) metabolites of the widely used antipyretic and analgesic drug acetaminophen and (2) activators of the ion channel TRPV1, an important downstream target for inflammatory mediators, in the phospholipase C (PLC)/TRPV1 signaling pathway. Evidence is presented for a fatty acid amide hydrolase (FAAH)-dependent fatty acid conjugation of p-aminophenol, a know
Popular Abstract in Swedish 1997 ökade långtidssjukskrivningarna i Sverige, vilka fortsatte att öka till och med 2002. Vanligtvis förklaras ökningen med orsaker på individnivå eller i arbetsmiljön. Genom att avgränsa avhandlingen till långtidssjukskrivningar bland arbetslösa, hamnar en annan förståelse i fokus, sammanfattad som att välfärdsstater utvecklar dold arbetslöshet bland dem med begränsadIn 1997 the number of long-term absences due to illness began and continued to rise in Sweden. Traditional explanations of why this is so have been centered on either blaming the individual or blaming the work environment. By focusing on long-term illness of the unemployed, this dissertation suggests that there is a growing residual unemployment within advanced welfare states. The main question th
This study concerns an arctic marine environment that was contaminated by actinide elements after a nuclear accident in 1968, the so-called Thule accident. In this study we have analyzed five isolated hot particles as well as sediment samples containing particles from the weapon material for the determination of the nuclear fingerprint of the accident. We report that the fissile material in the hy
