Search for fermiophobic Higgs bosons in final states with photons at LEP 2

Higgs boson production with subsequent decay to photons was searched for in the data collected by the DELPHI detector at centre-of-mass energies between 183 GeV and 209 GeV, corresponding to a total integrated luminosity of nearly 650 pb(-1). No evidence for a signal was found, and limits were set on h(0)Z(0) and h(0)A(0) production with h(0) decay to photons. These results were used to exclude re

Surprising facts in Swedish Grammar

In this paper I discuss two surprising facs in Swedish grammar, the presence of a particular active verb form, the supine, after auxiliary have in perfect and pluperfect, and the free word order found in the middle fielld of main clauses. The supine is not found in any other Germanic language, and is presumably to be seen as a result of a historical coincidence. The free word order in the middle f

Affinity partitioning of biotinylated mixed liposomes: effect of charge on biotin-NeutrAvidin interaction

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

Mellan det förflutna och framtiden : Den sandinistiska revolutionen i Nicaragua

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

Oxidized lipoprotein autoimmunity: an emerging drug target in cardiovascular disease

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 with severe sensory deficit: endoscopic release in 18 cases

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

Sårbar men inte ensam - en studie av några drababdes erfarenheter av Kemiraolyckan, tsunamin och stormen Gudrun

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

Effects of solvent exposure on testosterone levels and buturylcholinesterase activity in mice

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

Improving expressional power and validation for multilevel flow models

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

Asymmetric dimethylarginine and total homocysteine in plasma after oral methionine loading

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

Approximation results for kinetic variants of TSP

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

Improving numerical accuracy of Grobner basis polynomial equation solvers

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
