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

Avian mothers convey significant quantities of androgens (i.e. ?male? steroids) to their eggs, which are known to positively influence embryonic development, post-natal growth and competitive behaviour of the offspring. However, there is large inter-female variation in the amount of androgens transferred to the eggs. Recent studies suggest that this variation may be maintained because the positive

The dissertation explores the relationship between Aby Warburg’s unfinished picture atlas Mnemosyne and the visualization of Art History around 1800/1900 in an attempt to understand the historical conditions regarding the picture atlas and other visual devices constructed by Warburg and his staff at the Kulturwissenschaftlichen Bibliothek Warburg (K.B.W.) in Hamburg during the 1920s. The dissertat

Supervised learning methods are used when one wants to construct a classifier. To use such a method, one has to know the correct classification of at least some samples, which are used to train the classifier. Once a classifier has been trained it can be used to predict the class of unknown samples. Supervised learning methods have been used numerous times in genomic applications and we will only

In this paper simulations of a 130-nm CMOS 24-GHz automotive radar transmitter with digital beam steering is presented. The beam steering is performed by multiple PAs connected to separate antenna elements. The output phases of the PAs are individually controllable through 360

In this thesis eight papers are presented. They represent development of theory and implementation technique in quantum chemistry, as well applications. The first two papers describe advances in geometry optimization techniques. In the first of these papers a technique for achieving an approximate curvature description of the energy surface is presented and in the next a technique for inter molec

Pseudogenes are very common in the genomes of a wide range of organisms and, although they were originally considered as genetic junk, now several functions have been attributed to them. One important function of pseudogenes, as discussed in this chapter, is to provide material for genetic diversity. This is most prominent in the case of immunological recognition molecules such as immunoglobulins

It has been recently reported that both dynamic movement characteristics, as well as the duration of postures adopted during work, are important in the development of low back pain (LBP). This paper presents a video-based posture assessment method capable of measuring trunk angles and angular velocities in industrial workplaces. The interobserver reliability, system accuracy, and the relationship

This thesis examines the effect of water quality, habitat and species interactions on the occurrence and abundance of stream fishes in southern Sweden. I found that improvements in water quality between the 1960s and 1990s have led to recolonization of streams by brown trout (Salmo trutta L.), stone loach (Barbatula barbatula L.) and eel (Anguilla anguilla L.). The response was greatest for brown
