Detailed abundance analysis of 41 F and G type dwarf stars located in the solar neighborhood are presented. The stellar sample was selected to have kinematics intermediate between the Galactic thin and thick discs. The stars have been observed with the NOT telescope at La Palma, Spain in March 2006 and the ESO 2.2 m telescope at La Silla, Chile between October 1, 2004 and March 31, 2005. Abundance

We report on an all-sky search for periodic gravitational waves in the frequency band 50-800 Hz and with the frequency time derivative in the range of 0 through -6 x 10(-9) Hz/s. Such a signal could be produced by a nearby spinning and slightly nonaxisymmetric isolated neutron star in our Galaxy. After recent improvements in the search program that yielded a 10x increase in computational efficienc

We present the abundance analysis for a sample of 7 red giant branch stars in the metal-poor globular cluster NGC 4372 based on UVES spectra acquired as part of the Gaia-ESO Survey. This is the first extensive study of this cluster from high-resolution spectroscopy. We derive abundances of O, Na, Mg, Al, Si, Ca, Sc, Ti, Fe, Cr, Ni, Y, Ba, and La. We find a metallicity of [Fe/H] = -2.19 +/- 0.03 an

This paper presents an analysis of the point-spread functions (PSFs),which may be expected in the so-called improved seeing limited mode forthe Euro50 (Extremely large telescope with a 50 m aperture). This modecomprises adaptive control of the deformable secondary mirror of theaplanatic Gregorian telescope configuration using guide stars in a widefield. I may result in efficient compensation of tu

In this summary I briefly discuss some of the many interesting talks presented at this symposium.

Alla celler i samma kropp har samma genetiska information lagrad i DNA. Olika delar av den genetiska informationen är lagrade i en otillgänglig form. Vilken del av cellens DNA som är tillgänglig avgör sedan vilken specialisering cellen har. Genom att kontrollera vilken information som används kan man omprogrammera celler, till exempel kan en hudcell bli en hjärncell. En metod för att åstadkomma deAstrocytes are one of the most common types of cells found in the central nervous system, and they play an important supportive role for neurons and other brain cells. In order to obtain astrocytes for medical or experimental purposes, some protocols enable the production of astrocytes from stem cells, but it is of interest to be able to produce astrocytes from fibroblasts, a cell type found in th

Exercising your OA-affected joints is really important  Agneta had long struggled with pain in her right knee, but because she felt she could still manage daily life despite the discomfort, it took a while before she sought medical advice. However, delaying seeking care meant postponing the right treatment, which eventually led to an emergency hospital visit. At the hospital, she underwent an X-ra

Genetiska algoritmer utgör en grupp sökalgoritmer som hämtar inspiration från evolutionära processer i biologiska sammanhang. Genom att låta populationer av enskilda datasekvenser, exempelvis strängar av ettor och nollor, representera olika lösningar till ett givet problem, och sedan successivt låta datasekvenserna utbyta information sinsemellan, samt att genom mutationer modifiera dem, är det möjGenetic algorithms are complex constructs often used as heuristic search methods in contexts ranging from combinatorial optimisation to in silico evolution. They draw inspiration from the principles of biological evolution by utilizing the concepts of mutation, reproduction and selection in order to improve a population of solutions. The solutions are often represented as abstract data sequences,

Purpose: In order to study the Galactic Chemical Evolution, elemental abundances are needed. The purpose of this work is to investigate the chemical evolution of the Milky Way by determining several elemental abundances of giants in the local disk. Large surveys are up and coming, and several surveys are already working, and with these, the aim is high quality abundance measurements of several ele
