Influences on stratospheric aerosol during the first four months following the eruption of Kasatochi volcano (Alaska) were studied using observations at 10700 +/- 600 m altitude from the CARIBIC platform. Collected aerosol samples were analyzed for elemental constituents. Particle number concentrations were recorded in three size intervals together with ozone mixing ratios and slant column densiti
Biodiesel has recently reemerged as a common fuel. However, emissions from biodiesel combustion have been studied in much less detail than those from traditional petroleum-based diesel. In this experiment, emissions from the combustion of different fuel blends (BOO, B02, B20, B99, where the number after B indicates the percentage, by volume, of biodiesel in the fuel) in a VW TDi engine were analyz

Popular Abstract in Swedish Sedan den industriella revolutionen har världen konfronterats med många miljöproblem, t.ex. luftföroreningar, surt regn, global uppvärmning, farligt avfall, ozonhålsproblematik, ”smog” och vattenföroreningar. Det är viktigt att utveckla mätteknik för att objektivt kunna fastställa miljöförhållandena för att sedan kunna göra adekvata åtgärder. Miljön kan direkt karakteriThis thesis studies the techniques of laser remote sensing and their applications in environmental monitoring, as documented in several published papers. The environment where the human being live is degrading with an accelerating speed. Quantitative monitoring characterizes the quality of the environment and offers possibilities to solve environmental problems. Laser remote sensing actively prob
A search is presented for production of a heavy up-type quark (t') together with its antiparticle, assuming a significant branching ratio for subsequent decay into a W boson and a b quark. The search is based on 4.7 fb(-1) of pp collisions root s = 7 TeV recorded in 2011 with the ATLAS detector at the CERN Large Hadron Collider. Data are analyzed in the lepton + jets final state, characterized by
Genom EU-domstolens banbrytande avgörande i UsedSoft 2012 bekräftades att konsumtion av spridningsrätten kan ske till digitala kopior av datorprogram, förutsatt att kraven för en ”första försäljning” enligt artikel 4.2 dator-programdirektivet uppfylls. Domen innebar slutpunkten för den vedertagna uppfattningen att spridning av digitala verk ska klassificeras som tjänster, för vilka konsumtionsprinIn 2012, the CJEU confirmed in the landmark UsedSoft case, that the right of distribution right in regards to digital copies of computer program can be exhausted, provided that the requirements for a “first sale” according to Article 4.2 of the Software Directive is met. The ruling put an end to a previous ion that the distribution of digital copies of copyrighted works is considered as a service
IT ses ofta som en del av lösningen för att uppnå ett hållbart samhälle genom till exempel minskat resande, optimering av industri- och jordbruksprocesser, intelligenta elmätare och smarta hem. Något man sällan reflekterar över är att ITbranschen själv också bidrar till elanvändningen. Ett nytt fenomen inom IT-världen är molnet som ger möjlighet till som det verkar outtömliga resurser i form av laInformation and communication technology (ICT) is often seen as part of the solution for a sustainable society, for example through reduced travel, optimization of industrial and agricultural processes, smart meters and smart homes. However, something usually left unconsidered is the electricity consumption of ICT itself. A new phenomenon of the ICT industry is the Cloud that enables seemingly ine
Högestad utgör, med sina ca 13 000 ha, en del av Skånes största enskilda egendom med verksamhet inom jordbruk och skogsbruk, viltvård och fasigheter. Under våren 2006 inleddes ett samarbete mellan Högestad och Lunds universitet för en långsiktig hållbar utveckling. En del i samarbetet utgörs av tillgängligare information gällande forskningsresultat av t.ex. klimatförändringens påverkan av jordbrukHögestad is with an area of 13 000 ha one of the largest landowners in the southern part of Sweden (Skåne). In spring 2006, the collaboration between Högestad and Lund University for a long-term sustainable development was initiated. This collaboration comprises the easy access and transfer of information about new research results. These results include the effect of climate change on agriculture
Computer generated imagery is used in a wide range of disciplines, each with different requirements. As an example, real-time applications such as computer games have completely different restrictions and demands than offline rendering of feature films. A game has to render quickly using only limited resources, yet present visually adequate images. Film and visual effects rendering may not have st
We review the recent progress in dynamical and statistical downscaling approaches for west African precipitation and perform a regional climate model (RCM) intercomparison using the novel multi-model RCM data set from the Ensembles-based Predictions of Climate Changes and Their Impacts (ENSEMBLES) and African Monsoon Multidisciplinary Analyses (AMMA) projects. Present RCMs have distinct systematic
Roten till cancer? Cancer är en ledande orsak till en stor mängd dödsfall i världen och därför en fruktad sjukdom. Forskningen gör dock framsteg och man kommer allt närmre svaren på gåtorna. På senare år har det föreslagits att en speciell typ av celler, cancerstamceller, är drivande och ligger bakom flera av cancersjukdomarnas egenskaper. Alla organismer är uppbyggda av celler, den stora majoriIn recent years increasing evidence supporting the stem cell hypothesis have emerged and cancer stem cells (CSCs) have been reported to have been isolated in a wide variety of cancers. This CSC population has been attributed to contribute to the therapeutic resistance of many cancers and it is thus of great interest to find new therapeutic options targeting these cells. In ileal carcinoids however
Background: In any study with voluntary participation, self-selection risks leading to invalid conclusions. If the determinants of selection are observed, it is however possible to restore the parameters of interest by reweighting the sample to match the population, but this approach has seldom been applied in epidemiological research. Methods: We reweighted the Malmö Diet and Cancer (MDC) study b
Recurrent use of the Housing Enabler instrument has highlighted methodological challenges of broader scientific interest, namely interactions between personal functional capacity (P) and exposures to features (here potential barriers) in the built housing environment (E). This study aimed to propose and illustrate an analytic approach, separating P × E interaction effects (here accessibility probl
The recent history of the Ukrainian authoritarian far right is one of paradoxes. If one looks at the polls, it has performed poorly; its modest successes have been regional and short-lived. On the other hand, it has been highly successful in terms of shaping memory politics in the country. It has had a disproportional influence on history writing, having invested significant efforts into building
Over Boreal regions, monoterpenes emitted from the forest are the main precursors for secondary organic aerosol (SOA) formation and the primary driver of the growth of new aerosol particles to climatically important cloud condensation nuclei (CCN). Autoxidation of monoterpenes leads to rapid formation of Highly Oxygenated organic Molecules (HOM). We have developed the first model with near-explici
Dion–Jacobson (DJ) type 2D perovskites with a single organic cation layer exhibit a narrower distance between two adjacent inorganic layers compared to the corresponding Ruddlesden–Popper perovskites, which facilitates interlayer charge transport. However, the internal crystal structures in 2D DJ perovskites remain elusive. Herein, in a p-xylylenediamine (PDMA)-based DJ perovskite bearing bifuncti
A common molecular design paradigm for optical power limiting (OPL) applications is to introduce heavy atoms that promote intersystem crossing and triplet excited states. In order to investigate this effect, three multi-branched fluorene molecules were prepared where the central moiety was either an organic benzene unit, para-dibromobenzene, or a platinum(II)-alkynyl unit. All three molecules show
Experimental aerosol generation methods aim to represent natural processes; however, the complexity is not always captured and unforeseen variability may be introduced into the data. The current practices for natural and experimental aerosol generation techniques are reviewed here. Recommendations for best practice are presented, and include characterization of starting material and spray fluid, r
