Our clinical experience has suggested that the presently recommended patch-test concentration (1.0%) for formaldehyde in the baseline series might be too low. Therefore, consecutively patch-tested dermatitis patients were tested simultaneously with formaldehyde 1.0% and 2.0% (w/v) in aqua. Formaldehyde 1.0% and 2.0% were applied with a micro-pipette (15 microl) to filter paper discs in Finn Chambe
Benchmarking is an effective tool to compare the performance of full-scale wastewater treatment plant operation. In this study, 29 wastewater treatment plants from eight countries were surveyed with the aim of developing some key performance indicators, which may be used for benchmarking purposes. The level of utilisation of instrumentation, control and automation (ICA) has also been measured. The
Popular science summary: NADase – a way to avoid immune system activation? Streptococcus pyogenes (S. pyogenes) are bacteria that cause many different kinds of diseases in humans, for example strep throat, scarlet fever and necrotizing fasciitis, the ”flesh-eating disease”. An infection with this type of bacteria can also lead to heart and kidney damage, thought to be caused by our immune system
Utsagor från vittnen är ett väsentligt inslag i en effektiv rättskipning. Hot och våld mot vittnen utgör därför ett stort hinder i det brottsbekämpande ar-betet. Om det allmänna inte kan erbjuda vittnen ett tillräckligt skydd vid så-dana angrepp, finns det risk att vittnen väljer att inte samarbeta med polisen, vilket i sin tur kan få till följd att grova brott förblir ouppklarade. I denna studie Statements by witnesses are an essential element of the efficient administra-tion of justice. The occurrence of serious forms of threats and violence to-wards witnesses and their relatives therefore constitutes a major impediment to the work in combating crime. If the public cannot offer witnesses suffi-cient protection from attacks, there is a risk that they will choose not to co-operate with the
The increasingly frequent use of forensic evidence in the prosecution of criminal cases should in the long run result in increased analysis of its effectiveness. To date, such analysis has been limited, most probably due to rights of parties to use forensic evidence to support their respective arguments in cases and the rights of the courts to assess and rely on such evidence in criminal cases. Pr
Covid19 pandemin har inneburit stora utmaningar för psykisk hälsa globalt, dels på grund av begränsningar som införts för att minska smittspridningen såsom social distansering, men också rädslan som följer att leva under oroliga tider. Tidigare studier har bidragit till förklaringar av covid19’s effekter på psykisk hälsa genom att fokusera på antingen personlighetsbaserade eller kontextuella faktoThe covid19 pandemic has presented great challenges to mental health globally, in part due to restrictions implemented in the wake of the pandemic; such as social distancing, but also due to the fear and psychological distress associated with living during times of crisis. Prior studies have contributed to explaining covid19’s effects on mental health by addressing either personality-based or cont
Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices. In thi
Crystallisation of barium carbonate from alkaline silica solutions results in the formation of extraordinary micron-scale architectures exhibiting non-crystallographic curved shapes, such as helical filaments and worm-like braids. These so-called "silica biomorphs" consist of a textured assembly of uniform elongated witherite nanocrystallites, which is occasionally sheathed by a skin of amorphous
Several diesel exhaust (DE) characteristics, comprising both particle and gas phase, recognized as important when linking with health effects, are not reported in human chamber exposure studies. In order to understand effects of DE on humans there is a need for better characterization of DE when performing exposure studies. The aim of this study was to determine and quantify detailed DE characteri
Popular Abstract in Swedish Bakgrund Trots att venös blodpropp (venös tromboembolism [VTE]) är en viktig orsak till sjuklighet och dödlighet är data ofullständiga gällande dess förekomst och bakomliggande riskfaktorer hos oselekterade patienter. I begreppet VTE inkluderas blodproppar i benets djupa ådror (djup ventrombos [DVT]) och i lungorna (lungemboli [LE]). Insjuknandefrekvens i VTE varierar mDespite the fact that venous thromboembolism (VTE) is an important cause of morbidity and mortality there is still insufficient information on VTE risk factors and patient characteristics in the general population. Previously published incidences of VTE (deep venous thrombosis [DVT] and pulmonary embolism [PE]) vary from 71 to 192 per 100,000 individuals per year. Incidences of DVT and PE have bee
For some time it has been argued that cities all over the world have become more entrepreneurial and increasingly competitive. Most research has focused on spectacular events in well-known metropolises, but far less is known about how smaller cities engage in competitive activities. This paper focuses on how, why and what Swedish cities hope to achieve by engaging themselves in hosting the tryouts
Deactivation of SCR catalysts applied in bio fuel plants is a major problem due to higher amounts of potassium in bio fuel compared to other fuels. Regeneration of deactivated catalysts seems to be a promising way for minimising the total cost of bio fuel plants and great potential lies in finding regeneration processes that can be used commercially. The first applied regeneration method was washi
In this thesis I have investigated drivers of European Equity Long/Short hedge funds by analyzing the risk and return of individual Equity Long/Short hedge funds in different market environments. The results show that there are few macroeconomic drivers that can consistently explain the risk and return of individual European Equity Long/Short hedge funds. Running multifactor regression models on e

Expatriater är viktiga men också dyra tillgångar i multinationella företag. Expatriering innebär en stor utmaning i form av ett nytt arbete i ett nytt land, allt inbäddat i en ny kultur, ofta med ett främmande språk, vilket kräver nya sätt att hantera tillvaron. Då de flesta expatriater har familj, gäller det i högsta grad även den medföljande. Genom en kvalitativ studie med fenomenologiskt angrepExpatriates are important but also expensive assets in multinational companies. A new employment and a new country, all embedded in a new culture, often with a foreign language, makes expatriation a big challenge. This also highly affects accompanying partners, since most expatriates bring their families on the assignment. The process of expatriation was examined by a qualitative study with a phen
Den digitala utvecklingen har förändrat detaljhandelsbranschen i stor utsträckning. Priserna på e-handelsmarknaden är normalt sett lägre än priserna i fysiska butiker till följd av hård konkurrens, prismedvetna konsumenter och dynamisk prissättning (en prissättningsmodell som innebär att priserna på en produkt varierar flera gånger om dagen). Prismarknadsföring (realisationer, slutförsäljningar, uDigitalisation has had a significant impact on the retail industry. Due to strong competition, price-conscious consumers and dynamic pricing (a pricing strategy in which prices varies several times throughout the day) prices in E-commerce are usually lower than prices in traditional commerce. Under these circumstances, price reductions (sales, clearance sales and finale sales) and price comparison

Protein D (PD) is a highly conserved 42 kDa surface lipoprotein found in all Haemophilus influenzae, including nontypeable (NT) H. influenzae. PD is involved in the pathogenesis of respiratory tract infections, in the context of which it has been shown to impair ciliary function in a human nasopharyngeal tissue culture model and to augment the capacity to cause otitis media in rats. A likely mecha
