En barbar i Beirut II

Essän handlar om dagens Libanon och berör de kraftmätningar och konfliktlinjer som skakar landet såväl inifrån som utifrån (regionala och globala intressen). Den är ett slags fortsättning på en artikel om Beiruts förhistoria som tidigare publicerats i Ord & Bild (nr 6/2004) – och kommer att utgöra en del av ett större arbete som publiceras i bokform i början av 2007 på Glänta förlag.

"Distributed proton radiation therapy'' - A new concept for advanced competence support

The increased interest in high precision radiation therapy is to a large extent driven by the potential of modern imaging technology. The aim of this project was to analyse how an expensive proton facility best could support a multi-centre health care system. We have developed a model for distributed expert collaboration where all clinical experts will work close to their patients in regional cent

Photoluminescence spectra of a conjugated polymer: from films and solutions to single molecules

The purpose of this work is to address the issue of applicability of single-molecule spectroscopy (SMS) results for conjugated polymers to "bulk" samples, e.g. conjugated polymer films. Also, some apparent inconsistencies in the literature on SMS regarding the photoluminescence spectral position of conjugated polymers are discussed. We present a series of photoluminescence spectra of thin films of

Can we trust our memories? C. I. Lewiss coherence argument

In this paper we examine C. I. Lewis’s view on the role of coherence – what he calls “congruence” – in the justification of beliefs based on memory or testimony. Lewis has two main theses on the subject. His negative thesis states that coherence of independent items of evidence has no impact on the probability of a conclusion unless each item has some credibility of its own. The positive thesis sa

Analysis and modeling of field data on coastal morphological evolution over yearly and decadal time scales. Part 1: Background and linear techniques

A number of statistical techniques to analyze and model coastal morphological evolution over yearly and decadal (i.e., long-term) time scales based on field data are presented. After a general introduction to long-term morphological modeling, mainly linear methods are discussed, whereas nonlinear methods are treated in a companion paper (SOUTHGATE et al., 2001). The theoretical background to the m

Polymemse chain reaction using mixed primers. Cloning of human monoclonal antibody variable region genes from single hybridoma cells

We describe a general approach to rapidly obtain the DNA sequence encoding the variable region of any immunoglobulin chain using the polymerase chain reaction and a mixture of upstream primers corresponding to the leader sequence, and one downstream primer designed from the conserved nucleotide sequence of the constant region. The approach was applied to five different hybridomas producing human m

The role of phosphodiesterase 3B in energy metabolism

Energy metabolism at the level of any particular tissue is tightly regulated by hormones, neurotransmitters and cytokines in order to maintain overall energy homeostasis. Any dysfunctions in energy metabolism may lead to more or less severe consequences, with obesity and type 2 diabetes being the most prevalent ones. Type 2 diabetes is characterized by defective insulin secretion (?-cell dysfuncti

To trill or not to trill? Territorial response to a heterospecific vocal trait in male collared doves, Streptopelia decaocto

Responding of individuals outside the conspecific range has been largely explained by biases in sensory or cognitive systems toward particular traits or trait values. More recently, it has been shown that such responses might occur if individuals still respond to signal traits that have been lost over time. However, empirical evidence remains scarce. We report a case supporting the latter mechanis

Compression Ratio Influence on Maximum Load of a Natural Gas Fueled HCCI Engine

This paper discusses the compression ratio influence on maximum load of a Natural Gas HCCI engine. A modified Volvo TD100 truck engine is controlled in a closed-loop fashion by enriching the Natural Gas mixture with Hydrogen. The first section of the paper illustrates and discusses the potential of using hydrogen enrichment of natural gas to control combustion timing. Cylinder pressure is used as

Staphylococcal enterotoxin H induces V alpha-specific expansion of T cells.

Staphylococcal enterotoxin H (SEH) is a bacterial superantigen secreted by Staphylococcus aureus. Superantigens are presented on the MHC class II and activate large amounts of T cells by cross-linking APC and T cells. In this study, RT-PCR was used to show that SEH stimulates human T cells via the V domain of TCR, in particular V10 (TRAV27), while no TCR V-specific expansion was seen. This is in s

Defect engineering in Czochralski silicon by electron irradiation at different temperatures

Infrared absorption studies of defect formation in Czochralski silicon irradiated with fast electrons in a wide range of temperatures (80-900 K) have been performed. The samples with different contents of oxygen (O-16, O-18) and carbon (C-12, C-13) isotopes were investigated, The main defect reactions are found to depend strongly on irradiation temperature and dose, as well as on impurity content
