Investigation on the durability of man-made vitreous fibers in rat lungs.
Two types of sized stonewool with median lengths of 6.7 and 10.1 microns and median diameters of 0.63 and 0.85 microns, and crocidolite with fibers of median length of 4.8 microns and median diameter of 0.18 microns were instilled intratracheally into female Wistar rats. A single dose of 2 mg in 0.3 ml saline was used for the stonewool samples and 0.1 mg in 0.3 ml saline for crocidolite. The evenness of distribution of fibers in the lung was checked by scanning electron microscopy (SEM). Five animals per group were sacrificed after 2 days, 1, 3, 6, and 12 months. After low-temperature ashing of the lungs about 200 fibers per animal were analyzed by SEM for length and diameter. The number and mass of fibers in the total lung were calculated. For the stonewool samples the decrease in the number of fibers in the lung ash followed approximately first order kinetics resulting in half-times of 90 and 120 days. The analysis of fiber number and diameter of different length fractions was used to estimate the contribution of three processes of fiber elimination: transport by macrophages for short fibers, breakage of fibers, and dissolution of fibers. (The process of transport by macrophages was found fastest for fibers with length < 2.5 microns). For the elimination of critical fibers with length > 5 microns, the breakage and dissolution were the most important processes. The breakage of fibers was predominant for one of the stonewool samples. The preferential type of the mechanism of fiber elimination is dependent on chemical composition and size distribution
Extreme Lipoprotein(a) Levels and Improved Cardiovascular Risk Prediction
ObjectivesThe study tested whether extreme lipoprotein(a) levels and/or corresponding LPA risk genotypes improve myocardial infarction (MI) and coronary heart disease (CHD) risk prediction beyond conventional risk factors.BackgroundElevated lipoprotein(a) levels cause MI and CHD. Levels are primarily determined by variation in the LPA gene.MethodsWe followed 8,720 Danish participants in a general population study from 1991 to 1994 through 2011 without losses to follow-up. During this period, 730 and 1,683 first-time MI and CHD events occurred. Using predefined cutpoints for extreme lipoprotein(a) levels and/or corresponding LPA risk genotypes (kringle IV type 2 [KIV-2]) repeat polymorphism, rs3798220, and rs10455872 single nucleotide polymorphisms), we calculated net reclassification indices from <10% to 10% to 19.9% to ≥20% absolute 10-year MI and CHD risk.ResultsFor individuals with lipoprotein(a) levels ≥80th percentile (≥47 mg/dl), 23% (p < 0.001) of MI events and 12% (p < 0.001) of CHD events were reclassified correctly, while no events were reclassified incorrectly for either endpoint. As some incorrect reclassification of individuals with no events occurred, addition of lipoprotein(a) levels ≥80th percentile overall yielded net reclassification indices of +16% (95% confidence interval: 8% to 24%) and +3% (−1% to 8%) for MI and CHD, respectively. Corresponding net reclassification indices for number of KIV-2 repeats ≤21st percentile were +12% (5% to 19%) and +4% (0% to 8%), for rs3798220 carrier status +15% (−14% to 44%) and +10% (−10% to 30%), and for rs10455872 carrier status +16% (6% to 26%) and +2% (−1% to 6%). Considering only individuals at 10% to 19.9% absolute 10-year MI and CHD risk, addition of extreme lipoprotein(a) levels or corresponding LPA risk genotypes improved risk prediction even further.ConclusionsExtreme lipoprotein(a) levels or corresponding LPA KIV-2/rs10455872 risk genotypes substantially improved MI and CHD risk prediction
«Sånn vil jeg ha det hvis vi skal være venner!» : Anerkjennelse som betingelse for barns trivsel i skoletiden
Denne studien tar for seg elevers erfaringer med sosiale relasjoner i eget miljø og baserer seg på kvalitative intervju. Det er gjennomført to gruppeintervju med fem mellomtrinnslever i hvert intervju. Spørsmålene skulle få barna til å beskrive hva som er av betydning når en relasjon med medelever oppleves som god, og hva som er av betydning når en relasjon med lærere oppleves som god. De ble også spurt om hva andre kan gjøre for at barn skal få det bedre.
Hensikten med prosjektet er å gi leseren dypere innsikt i hva barn mener kan gjøres for at barn skal oppleve gode relasjoner med medelever og lærere.
Barnas perspektiver presenteres gjennom en tematisk fremstilling av materialet, og ses i lys av Axel Honneths teori om anerkjennelse i tre sfærer.
Resultatene viser at det barna mener er av betydning for at en relasjon med medelever og/eller lærere skal oppleves som god, kan forstås i tråd med begrepene tilhørighet, intersubjektivitet og autoritativitet, som igjen kan knyttes til anerkjennelse i sfæren for tilhørighet, sfæren for rettigheter og rettferdighet, og sfæren for solidaritet
Crowdsourcing and the Architectural Competition as Organisational Technologies
In this dissertation, I take interest in crowdsourcing and architectural competitions as I focus
on examining how a crowdsourcing platform works in the building industry and how the
practices unfolding on it relates to – and maybe mimics – architectural competitions. The
platform is operated and situated in the building industry, where ‘the architectural
competition’ stands as an institution for how to coordinate interactions between actors. I also
take interest in an architectural competition setup where dialogue between architects and
jury is part of the setup. In overall terms, the research project aims to contribute to
understanding novel interaction practices in the building industry and the architectural world
at large. The research is based primarily on ethnographic explorations and the results hereof
is the article-based dissertation you have just embarked on.
The dissertation is structured in two parts, where the first contains most of the framework
and plays the role of an extended reading guide to the three articles presented in the second
part, which also contains the conclusion
