The first modern Swedish checklist of fungus gnats of the families Bolitophilidae, Diadocidiidae, Ditomyiidae, Keroplatidae and Mycetophilidae is presented. The checklist results from a comprehensive literature research as well as treatment of a considerable determined and undetermined material from Swedish museum collections and recent material from several sources. To get better grounds for judg

A new fragrance mix (FM II), with 6 frequently used chemicals not present in the currently used fragrance mix (FM I), was evaluated in 6 dermatological centres in Europe, as previously reported. In this publication, test results with the individual constituents and after repeated open application test (ROAT) of FM II are described. Furthermore, cosmetic products which had caused a contact dermatit

Popular Abstract in Swedish I en komponent som utsätts för upprepande på- och avlastningar, d.v.s. cyklisk belastning, kan defekter i form av sprickor initieras och börja växa. Detta fenomen kallas utmattning och kan leda till haveri med potentiellt katastrofala följder. Det är därför viktigt att förstå fenomenen som ligger bakom utmattning och att ha tillförlitliga modeller för att förutsäga livsUnderstanding of the growth of fatigue cracks is of utmost importance since such growth often has a profound influence on the life of components subjected to cyclic loading. Thus, reliable fatigue life models enable a more efficient use of materials and improve the performance and efficiency in many applications. This thesis deals with the growth of fatigue cracks subjected to high load amplitude

Popular Abstract in Swedish Den här avhandlingen är ett bidrag till utvecklingen av en metodik som gör det möjligt att med hjälp av fossila pollen d.v.s. pollen som lagrats i mossar och sjöar, rekonstruera historiska och förhistoriska landskap så precist som möjligt vad gäller utbredning av skog, olika typer av öppen mark samt vegetationens sammansättning. Den tolknings metodik som för närvarande Fossil pollen records retrieved from peat and lake sediments have great potential for quantifying past plant cover. This thesis is a contribution to the development of a palynological interpretation tool for reconstructing past cultural landscapes in terms of plant abundance and distribution. The aims of this thesis are (1) to explore pollen-vegetation relationships in the ancient, traditional cul

Unicellular photosynthetic golden algae called diatoms are one of the most abundant silicifying organisms. Diatoms take up silicon and build their frustules, in the form of biogenic silica (BSi), which have high preservation potential, and thus are found in sediments. Around 27 % of the annual dissolved silicon (DSi) delivery from the land to the ocean is retained in lakes and reservoirs in the fo

Many patients with outlet obstruction secondary to prostatic enlargement have lower urinary tract symptoms (LUTSs) and an increased frequency of micturition. The standard treatment is transurethral resection of the prostate (TURP), which alleviates obstruction and symptoms. However, after TURP, 20–40 percent of patients continue to experience LUTSs. The aim of the present study in rats was to iden

Work and fun have traditionally been seen as opposites. There is however increasing interest among academics and businesses in the potential benefits of uniting the two. Yet, not a great deal has been studied on how managers are to impact such a process. The literature often sees the role of managers limited to that of “party planners” where they conduct a series of fun activities, with varying an

Efter en lång period där många bränder härjade i Sveriges storstäder förbjöds höga trähus. Denna lag upphörde att gälla i mitten på 90-talet och sedan dess har intresset för höga trähus ökat. Detta har resulterat i att behovet av bra ljudisoleringslösningar har blivit större. På grund av det växande intresset för miljöfrågor har det blivit viktigare för företag att hitta nya lösningar för att taIn the last years, the interest in high-rise timber framed building has gone up resulting in an increased demand for good solutions regarding sound insulation. Due to the worldwide growing interest in environmental issues, it has become of greater importance for companies to find ways to take care of their residue, instead of throwing it away. This can benefit both the environment, as less new mat

Surveillance cameras are vital in the nuclear power industry where the reactor equipment must constantly be kept under surveillance to maintain safety. Constant monitoring is however difficult due to the highly radioactive environment, which cause cameras to malfunction and eventually break. Malfunction typically manifests itself as quality degradation of the image from the cameras. Initially, tem

The purpose for which the study was conducted was to investigate firm-specific advantages of standardization, and how standardization routines optimized and changing as intra organizational learning. The study was conducted as a qualitative case study where the pattern matching method is used to compare and analyse the collected data against a pre-constructed theoretical framework. The theoretica

Ditt pipetteringsinstrument skulle kunna vägleda dig och leverera information om förändringar eller problem i realtid. Genom att kontinuerligt undersöka sensordata kan maskininlärningsalgoritmer vara ett kraftfullt verktyg för att utvärdera olika aspekter och hålla dig informerad om möjliga fel som uppstår under arbetet. Detta skulle kunna förhindra dolda fel som volym- eller densitetsavvikelser Thermo Fisher Scientific manufacture automatic pipetting instruments for diagnostic tests. These tests are sensitive to abnormalities and changes in e.g. volume or density could potentially lead to less precision or other issues in the pipetting work flow. Utilizing data collected from a pressure sensor inside the pipette could be a way of automatically verifying different aspects related to the p

This work focuses on the southern part of Sollentuna municipality and the adjacent suburbs of Kista, Husby and Akalla located in the northernmost part of Stockholm municipality, which henceforth will be referred to as “Kista”. The urban core of Sollentuna/Kista is strategically located both close to Stockholm but also along the north going road towards both Arlanda airport and Swedens fourth city

Elnätet står inför stora utmaningar de kommande åren med frågor såsom decentraliserad produktion, planerad nybyggnation och ett mer elektrifierat samhälle. Detta lyfter frågan om vad som kan göras idag för att använda elnätet mer effektivt och med vilka metoder elnätsbolag kan bedöma hur mycket kapacitet som finns tillgänglig i nätet. Arbetet bygger på kunddata från ca 4 500 kunder under en fördel\addcontentsline{toc}{section}{Abstract} \section*{\Large \textbf{Abstract}} The power grid needs to develop substantially the next few years to accommodate decentralized production, planned expansions and a more electricity dependent society. This raises the question of what can be done today to use the existing grid more efficiently and which methods the distribution system operator (DSO) can

Brukaranalyser, eller analyser med syfte att identifiera och framlägga bevis för vem som använt viss enhet eller något som anses anslutet till viss enhet under viss tid, är numera vanligt förekommande i brottmålsprocessen. Alltjämt föreligger dock utrymme för diskussion kring användningen av bevismedlet. Det övergripande syftet med uppsatsen är därav att analysera och problematisera hur brukaranalUser analysis, an analysis carried out with the aim of identifying and providing evidence of who used a particular device, or something considered to be connected to a particular device over a certain period of time, is often presented as evidence in the Swedish criminal procedure. However, there is still room for discussion regarding the usage of such evidence. Therefore, general aim of this thes

We investigated the skin sensitization hazard of glyphosate, the surfactant polyethylated tallow amine (POEA) and two commercial glyphosate-containing formulations using different omics-technologies based on a human dendritic cell (DC)-like cell line. First, the GARD™skin assay, investigating changes in the expression of 200 transcripts upon cell exposure to xenobiotics, was used for skin sensitiz

Financial services sector is fundamental to economic growth and development in all advanced economies. Financial services such as banking, savings and investment, insurance, and debt and equity financing constitute a nation's economic engine by fulfilling three core functions in the economy. Firstly, these services provide financial intermediation functions between savers/investors that are lo

Parallel trade in goods is generally viewed as a positive phenomenon within the EU as a consequence of the principle free movement of goods: When traders buy goods in one part of the common market at a low price and transfer it to a higher priced area, allowing them to undercut those prices, then this will enhance competition, drive down prices and give consumers more choice- an overall positive e

Motorfordonsbranschen har sedan nästan 20 år tillbaka reglerats av gruppundantag. Det har dock kunnat konstateras att konkurrensen inte varit tillräcklig på den gemensamma marknaden. Leverantörerna har kunnat använda sig av kombinerade exklusiva och selektiva distributionssystem och därigenom i praktiken kunnat uppnå en marknadsuppdelning. Inommärkeskonkurrensen har varit bristfällig då återförsäl
