The partitioning behaviour of biotinylated mixed liposomes in aqueous poly(ethylene glycol)/dextran two-phase systems containing NeutrAvidin-dextran suggests that the biotin-NeutrAvidin affinity interaction is charge dependent. Biotinylated phosphatidylcholine liposomes with a low negative surface charge distributed in the NeutrAvidin-containing bottom phase at neutral pH, but the introduction of

The theme throughout this book is the buildning up of a new societal structure and the conflicts encompassed in such a project. I discuss the societal changes in Sandinista Nicaragua by way of placing the revolution in a historic, political, and social context. Throughout the work process it became increasingly clear that the conflicts of the FSLN were in principal due to two factors. First, the F

Oxidative modification of low-density lipoprotein (LDL) in the arterial wall is believed to be one of the most important mechanisms involved in the development of atherosclerosis. It is well established that oxidized (Ox)-LDL uptake is responsible for the formation of macrophage foam cells, one of the most characteristic hallmarks of the atherosclerotic plaque, and that the proinflammatory and cyt

Carpal tunnel syndrome (CTS) with severe sensory deficit was treated with endoscopic carpal tunnel release in 18 hands of 16 consecutive patients (median age 72 (28-92) years). In all hands, preoperative 2-point discrimination (2-PD) exceeded 15 mm in the radial and ulnar sides of the pulps of at least 2 of the 3 radial digits. All patients underwent an independent evaluation and answered a questi

The aim of this report is to illustrate how the affected after disasters have experienced their situation and the support from authorities. The study is based on interviews with 16 persons after the storm Gudrun in southern Sweden 2005, the Asian tsunami 2004 and an accident with toxic gas in a Swedish town 2005. The affected received most support, both practical and emotional, from their social

In female and male mice the effect of exposure to trichloroethylene (TCE) seen at the lowest concentration is an increase in liver weight. The activity of plasma butyrylcholinesterase (BuChE) increases even more than the liver weight at corresponding concentrations, but only in the males. Depletion of testosterone through castration or destruction of the pituitary gland or hypothalamus, are the on

Multilevel flow modeling (MFM) is a modeling method for complex technical systems in which the goals and functions of the system are explicitly described. MFM can be used as a basis for root cause analysis, where primary root causes are separated from consequential faults, in complex fault situations. Model representations for use in diagnostic reasoning usually describe causality, between paramet

Background: Elevation of homocysteine (Hcy) and asymmetric dimethylarginine (ADMA) in plasma are believed to be involved in the pathogenesis of cardiovascular disease (CVD). In humans, oral methionine loading results in acute elevation of plasma Hcy. This is associated with impaired NO-dependent vasodilatation, a mechanism that may explain the relationship between elevated Hcy and risk of CVD. ADM

We study the approximation complexity of certain kinetic variants of the Traveling Salesman Problem (TSP) where we consider instances in which each point moves with a fixed constant speed in a fixed direction. We prove the following results: 1. If the points all move with the same velocity, then there is a polynomial time approximation scheme for the Kinetic TSP. 2. The Kinetic TSP cannot be appro

This paper presents techniques for improving the numerical stability of Grobner basis solvers for polynomial equations. Recently Grobner basis methods have been used succesfully to solve polynomial equations arising in global optimization e.g. three view triangulation and in many important minimal cases of structure from motion. Such methods work extremely well for problems of reasonably low degre

Popular Abstract in Swedish Talarålder är en viktig paralingvistisk egenskap i tal, som bör beaktas vid studiet av fonetisk variation. Kunskap om talarålder kan användas för att förbättra talteknologiska tillämpningar såsom automatisk taligenkänning och talsyntes. Föreliggande doktorsavhandling beskriver sex studier som undersökt ett flertal aspekter av den åldersrelaterade variationen i tal. NärSpeaker age is an important paralinguistic feature in speech which has to be considered in the study of phonetic variation. Knowledge about this feature may be used to improve speech technology applications, e.g. automatic speech recognition and speech synthesis. The present thesis describes six studies of several phonetic aspects of age-related variation in speech. As the speech production mecha

The academic discourse on the need for a shared political public sphere at the level of the European Union has in recent years produced the conventional wisdom that such an emerging transnational community of communication is already observable in the mass media. However, the empirical indicators on which this notion is based tend to accommodate parallel national public spheres rather than a genui

The synthesis and characterization of the title trisphenolate ligand are described. From its reaction with manganese(iii) three complexes were isolated. The crystal structures revealed one pentacoordinate monomer and two similar dimers with different solvents of crystallization. In the dimers the metal ions are hexacoordinate and connected through bridging of two phenolates. A combination of elect
