Both natural and synthetic polyelectrolytes form strong complexes with a variety of proteins. One peculiar phenomenon is that association can take place even when the protein and the polyelectrolyte carry the same charge. This has been interpreted as if the ion-dipole interaction can overcome the repulsive ion-ion interaction. On the basis of Monte Carlo simulations and perturbation theory, we pro
Background. Male fetal gender is associated with an overall increased risk of pre-eclampsia. However, it was recently shown that the male: female birth ratio was decreased in pre-eclampsia associated with preterm delivery. The reason for this discrepancy is not known. Objective. To investigate whether the fetal and newborn gender is associated with the incidence of antenatal maternal pregnancy com
This doctoral thesis deals with two closely interconnected phenomena, the adoption and diffusion of innovations. The research aims at developing both the theory of individual adoption decisions and the theory of the diffusion of an innovation in society. Especially how the pricing of an innovation tends to influence adoption and diffusion is focused. Two empirical studies within the telecommunicat
Aortas and portal veins from spontaneously hypertensive rats (SHR) and matched normotensive Wistar-Kyoto rats (WKY) were studied with respect to their energy turnover and mechanical properties. Relaxed aortas fom SHR 16--17 weeks and 20--25 weeks of age were stiffer, had smaller circumference, and greater maximal active wall tension compared to WKY aortas. Active stress (forced/areas) was not diff
Popular Abstract in Swedish Det är känt att låg socioekonomisk position (t.ex., låg inkomst, kort utbildning) och civilstånd, (t.ex., ensamstående) kan försämra hälsan. Den sämre hälsan medför ett ökat sjukvårdsbehov, och i ett jämlikt samhälle borde därför sjukvårdsutnyttjandet vara större bland de med låg socioekonomisk position och bland de som är ensamstående. Av samma anledning bör en högre fBesides individual characteristics, people born in the same country may present a related pattern of health status and health care utilisation, perhaps because they share a number of socioeconomic and cultural characteristics in addition to their common geographic origin and language. Rather than using simple ethnical or geographical categories, we apply multilevel regression analysis with individ
The work presented deals with the characterisation and application of critical gels. In order to provide a theoretical foundation, the thermodynamics of the reversible swelling and shrinking behaviour of such gels is outlined. The temperature-sensitive poly(N-isopropylacrylamide) gel (NiPAAm) was chosen for experimental investigation. Dif ferent methods of producing the gel are described, and the

The first chapter develops a theoretical model of marriage and divorce. The model has two periods and assumes Pareto efficient time allocations. There is a risk of divorce in the second period, which is modeled as exogenously given. The second chapter utilizes the model developed in the previous chapter to analyze the equality between married men and women. Equality is defined as the spouses' rel
Topological properties of "scale-free" networks are investigated by determining their spectral dimensions d(S), which reflect a diffusion process in the corresponding graphs. Data bases for citation networks and metabolic networks together with simulation results from the growing network model [A.-L. Barabasi and R. Albert, Science 286, 509 (1999)] are probed. For completeness and comparisons latt
Flux reductions experienced during ultrafiltration are due either to concentration polarization or fouling. It is usually difficult to distinguish between these two phenomena, but by using a turbulence-promoting module it is possible to determine the reversibility of a flux reduction, and thus distinguish between concentration polarization and fouling. By using a turbulence-promoting module, it is
Soft tissue and skeletal chondromas are rare entities, and only 21 cases with abnormal karyotypes have been reported. A survey of these, and 10 new cases reported herein, showed that the 12q13-15 segment is nonrandomly involved in structural rearrangements in chondromas. The HMGA2 (HMGI-C) locus in 12q15 is frequently rearranged in other benign mesenchymal tumors, and this study aimed at character
Angle-resolved electrons from laser-Assisted photoionization from atoms are simulated using Time-Dependent Configuration-Interaction Singles. The distributions are interpreted using a propensity rule for transitions in the continuum.
Microvesicles are shed from cell surfaces during infectious or inflammatory conditions and may contribute to the pathogenesis of disease. During Shiga toxin-producing Escherichia coli (STEC) infection, microvesicles are released from blood cells. These microvesicles play a part in inflammation, thrombosis, hemolysis, and the transfer of the main virulence factor of STEC strains, Shiga toxin, to ta
This study investigated the idea that youth’s perceptions of the frequency of family political discussions and of parental political support mostly derive from their own political interest, a form of projection bias. Tests were performed of whether the same bias applies to parents, and whether youth’s and parents’ perceptions of political discussions and political support overlap to only a limited
Objective: To estimate the genetic contribution to traumatic and degenerative meniscus tears for men and women across the lifespan. Methods: We linked the Swedish Twin Register with individual-level national healthcare data to form a 30-year, population-wide, longitudinal twin cohort. To study genetic contribution to meniscus tears, we estimated the heritability and familial risk using incident tr
Liquid chromatography-mass spectrometry (LC-MS) and mass spectrometry imaging (MSI) are two techniques that are routinely used to study proteins, peptides, and metabolites at a large scale. Thousands of biological compounds can be identified and quantified in a single experiment with LC-MS, but many studies fail to convert this data to a better understanding of disease biology. One of the primary
BACKGROUND: The identification of novel predictors of poor outcome may help stratify cardiovascular risk. Aim was to evaluate the individual contribution of blood cell count parameters, as well as their clustering, on the risk of death and cardiovascular events over the long term in the population-based Malmö Diet and Cancer Study cohort.METHODS: In 30,447 individuals (age 57 ± 8 years), we assess
This paper tests if a strong labor movement leads to fewer industrial conflicts. The focus is on Sweden between the first general election in 1919 and the famous Saltsjöbaden Agreement in 1938, a formative period when the country transitioned from fierce labor conflicts to a state of industrial peace. Using panel data techniques to analyze more than 2,000 strikes in 103 Swedish towns, we find that
This volume discusses the topics of sin, suffering, and evil in the Hebrew Bible. It gathers fresh and innovative perspectives provided by internationally renowned biblical scholars that not only demonstrate ways in which these topics are dealt with in the Hebrew Bible itself, but also map out their lasting impact on human experience of suffering throughout history. Put into dialogue with the thou
