Experimental study of thermal breakdown products from halogenated extinguishing agents
Thermal breakdown products from four different fire extinguishing agents have been analysed. The agents studied were: bromotrifluoromethane (Halon 1301), pentafluoroethane (HFC 125), heptafluoropropane (HFC 227ea) and dodecafluoro-2-methyl-pentane-3-one (C6F-ketone). In the tests, the studied agent was introduced into a propane flame in a diffusion flame burner. The combustion products were analys
Do we need PSA and early detection of prostate cancer?
The limitations of PSA as a screening marker for diagnosis and prostate cancer treatment are well known. The low specificity of PSA results in many unnecessary prostate biopsies, furthermore high rates of over-detection and overtreatment affect patients' quality of life. New assays measuring different molecular forms of PSA have resulted only in a moderate improvement of specificity especially bey

Kynurenic Acid levels in cerebrospinal fluid from patients with Alzheimer's disease or dementia with lewy bodies.
Kynurenic acid (KYNA) is implicated in cognitive functions. Altered concentrations of the compound are found in serum and cerebrospinal fluid (CSF) of patients with Alzheimer's disease (AD). Further studies to determine whether KYNA serves as a biomarker for cognitive decline and dementia progression are required. In this study, we measured CSF KYNA levels in AD patients (n = 19), patients with de
Microscopic approach to second harmonic generation in quantum cascade lasers
Second harmonic generation is analyzed from a microscopical point of view using a non-equilibrium Green's function formalism. Through this approach the complete on-state of the laser can be modeled and results are compared to experiment with good agreement. In addition, higher order current response is extracted from the calculations and together with waveguide properties, these currents provide t
Phylogeography of a Habitat Specialist with High Dispersal Capability: The Savi’s Warbler Locustella luscinioides
In order to describe the influence of Pleistocene glaciations on the genetic structure and demography of a highly mobile, but specialized, passerine, the Savi’s Warbler (Locustella luscinioides), mitochondrial DNA sequences (ND2) and microsatellites were analysed in c.330 individuals of 17 breeding and two wintering populations. Phylogenetic, population genetics and coalescent methods were used to
Using motion interactive games to promote physical activity and enhance motor performance in children with cerebral palsy
Objective: To explore the feasibility of using low-cost motion interactive games as a home-based intervention for children with cerebral palsy (CP). Methods: Fourteen children with CP, 6-16 years old, practiced with the EyeToy for PlayStation2 (R) in their homes during 4 weeks. Outcome measures were physical activity monitors, Movement Assessment Battery for Children-2 (mABC-2), Bruininks-Oseretsk

New electrode materials based on functionalized polypyrrole
New functional electrode materials, based on polypyrrole, were prepared by potentiostatic electro-copolymerization of pyrrole with two different pyrrole monomers, functionalized with carboxylic group: 3-(1-pyrrolyl)-propanoic acid and 4-oxo-4(1H-pyrrole-3-yl)butanoic acid. The properties of the polymeric electrode materials depend mainly on the synthesis method, monomers ratio, reaction time, and
Temperature dependent exciton-exciton annihilation in the LH2 antenna complex
Two-color pump-probe measurements of the peripheral light harvesting complex LH2 of Rb.sphaeroides reveal strong temperature dependence of the annihilation rate. The experimental results were modeled via multi-exciton density matrix theory. Based on available literature data we can set an upper limit for the feasible intramolecular internal conversion rate. We show that this also restricts the pos
Electronic photon echo spectroscopy and vibrations
Coupling between electronic and nuclear degrees of freedom in Rhodamine 800 has been studied using fluorescence line narrowing (FLN) and three-pulse photon echo peak shift (3PEPS). From the FLN measurement we extract the Huang-Rhys S-factors and frequencies of 16 Franck-Condon active vibrations clustered in two groups centred around 350 cm(-1) and 1400 cm(-1). The five modes below 500 cm(-1) cover

Storage ring at HIE-ISOLDE Technical design report
We propose to install a storage ring at an ISOL-type radioactive beam facility for the first time. Specifically, we intend to setup the heavy-ion, low-energy ring TSR at the HIE-ISOLDE facility in CERN, Geneva. Such a facility will provide a capability for experiments with stored secondary beams that is unique in the world. The envisaged physics programme is rich and varied, spanning from investig

European consensus statement on diagnosis and treatment of adult ADHD: The European Network Adult ADHD
Background: Attention deficit hyperactivity disorder (ADHD) is among the most common psychiatric disorders of childhood that persists into adulthood in the majority of cases. The evidence on persistence poses several difficulties for adult psychiatry considering the lack of expertise for diagnostic assessment, limited treatment options and patient facilities across Europe. Methods: The European Ne
Coprolite morphotypes from the Upper Cretaceous of Sweden: novel views on an ancient ecosystem and implications for coprolite taphonomy
Coprolites (fossilized faeces) are common, yet previously unreported, elements in the Campanian (Upper Cretaceous) shallow-marine strata of Asen, southern Sweden. They are associated with a diverse vertebrate fauna and comprise at least seven different morphotypes that suggest a variety of source animals. Their faecal origin is corroborated by several lines of evidence, including chemical composit

Le respect de la tradition : Om den franska flöjtkonsten: dess lärande, hantverk och estetik i ett hermeneutiskt perspektiv
ABSTRACT The present study describes topics related to music education, and the education of flautists, primarily on a professional level, covering a period from early 18th Century up to the early 21st Century within the French flute tradition. Further related areas of importance are concepts such as intuition, imitation, mimeses and maieutics and their relation to a flautist’s learning and teachi
