During the last decades, there has been concern that the environmental contaminants, such as POPs, may contribute to sex ratio changes in offspring of exposed populations. Accidental exposure to TCDD has been shown to be associated with fewer sons in men who were exposed in adolescence or earlier in life. However, it is not known whether POPs could change the proportion of X- and Y-sperm. A variet

Vasopressin and oxytocin are synthesised in the hypothalamus and released to the blood stream via the posterior lobe of the hypophysis. Research during later years has shown that these peptides are also produced in other parts of the brain. The secretion to plasma is stimulated by oestrogen, an effect which is counteracted by progestagen. During delivery the fetus can also produce substantial amou

The present study deals with the question of cult locales in city gate contexts in Iron Age Palestine. Both archaeological and biblical sources are analysed in order to determine the presence of gate cult locales and indicate some directions of interpretation. A general framework for the archaeological identification of cult (as proposed by Colin Renfrew and others) is discussed and applied within

This work presents a way of analysing photographs stored in Canon’s CR2-format in order to analyse the light intensity profile of the area where the photographs were taken. A set of underwater photographs of the habitat of the Cuttlefish, Sepia officinalis, were provided for this thesis. The light intensity profile of the habitat of the cuttlefish is of interest because of the unusual shape of its pupil

This paper investigates if liquidity (or illiquidity) is a factor influencing returns on the Swedish stock market during the period of January 2001 to December of 2010. The time-series effects of illiquidity as well as differences in the effects of illiquidity across stocks with different characteristics are investigated. In addition, the paper addresses the question of whether sensitivity of stoc

Extreme events on the financial market has become an important and high-attention topic. Several well know historical market crashes has taken investors and academics with surprise and there is an urge to understand these anomalous events. The Johansen-Ledoit-Sornette model aims to describe speculative bubbles and anti bubbles on financial markets, often ending in endogenous crashes or rebounds. I

In this study I examine the ways that social policy and (step)family discourse are constituted by the cultural and legal priority granted to biological kinship ties. I call the discourses that perpetuate the primacy of biological kinship the politics of biology. The purpose of the study is to examine the ways that the politics of biology are constituted, expressed and challenged in Swedish late mo

The right of access to medicines has challenged the common perception that economic, social and cultural rights, due to their progressive character, are aspirations rather than a legal set of obligations. It has received strong and sustainable global support and has achieved a remarkably detailed legal definition within the UN human rights system, including the provision of access to essential med

This thesis examines cluster and innovation system theory’s answer to why some firms, and not others, based in particular nations achieve international success in distinct segments, and the European Union’s recent policy efforts based on such theories. On this background a discussion on the changes needed in national economic policymaking among EU Member States when the EU starts taking a cluster

Lactococcus lactis ssp. lactis ATCC 19435 is known to produce mixed acids when grown on maltose. A change in fermentation conditions only, elevated temperatures (up to 37 °C) and reduced pH values (down to 5.0) resulted in a shift towards homolactic product formation. This was accompanied by decreased growth rate and cell yield. The results are discussed in terms of redox balance and maintenance,

Aim: The purpose of the study was to assess the association between seropositivity to various infectious agents and stable coronary artery disease (CAD), controlling simultaneously for a variety of potential confounders. We also investigated whether the choice of a larger reference group might affect the results, and whether or not seropositivity to multiple agents was associated with a systemic i

Owing to an orderly recruitment of motor units, low threshold type I fibres are presumed to be vulnerable in contractions of long duration. To study load on these fibres muscular rest was registered as the time fraction of electromyographic (EMG) activity below a threshold. Moreover, the frequency of periods with muscular rest, EMG gaps, was derived, since a low gap frequency has been shown to be
