This talk describes the various stages of ATLAS Data Challenge 2 (DC2) in what concerns usage of resources deployed via NorduGrid's Advanced Resource Connector (ARC). It also describes the integration of these resources with the ATLAS production system using the Dulcinea executor. ATLAS Data Challenge 2 (DC2), run in 2004, was designed to be a step forward in the distributed data processing. In p

The problem of empty names derives from the fact that empty names fail to refer. The reference failure of empty names implies that sentences containing empty names lack truth-conditions. As a consequence those sentences are meaningless, according to many theories of meaning. The present dissertation addresses the problem of empty names and proposes a solution to the problem at hand. In brief, the

Structure from sound can be phrased as the problem of determining the position of a number of microphones and a number of sound sources given only the recorded sounds. In this paper we study minimal structure from sound problems in both TOA (time of arrival) and TDOA (time difference of arrival) settings with collinear constraints on e.g. the microphone positions. Three such minimal cases are anal

Background Variations in colonoscopy practice exist, which may be related to healthcare quality. Aims To determine factors associated with three performance indicators of colonoscopy: complete colonoscopy, adenomatous polyp diagnosis, and duration. Patients Consecutive patients referred for colonoscopy from 21 centres in 11 countries. Methods This prospective observational study used multiple

Introduction: In a cold,wet, or windy environment, cold exposure can be considerable for an injured or ill person. The subsequent autonomous stress response initially will increase circulatory and respiratory demands, and as body core temperature declines, the patient’s condition might deteriorate. Therefore, the application of adequate insulation to reduce cold exposure and prevent body core cool

Popular Abstract in Swedish Den här avhandlingen beskriver olika experimentella metoder att framställa nanopartiklar med kontroll över storlek och sammansättning. En nanopartikel är en partikel som är mindre än 100 nanometer (1 nm är en miljondels millimeter). Utmaningen ligger i att partiklarna är såpass små. En nanopartikel förhåller sig ungefär storleksmässigt till en tennisboll som en tennisboThis thesis describes experiments performed using different methods to produce aerosol nanoparticles with control over size and composition. The process included differential mobility analyzers (DMAs) as size-selecting instruments and tube furnaces for particle synthesis. A method to estimate the degradation of the DMA performance from the ideal case for individual DMAs was proposed and tested ex

C-fibre neuropeptides, such as tachykinins and calcitonin-gene related peptide (CGRP), play an important role in neurogenic inflammation. The present work deals with five different aspects of the physiology and pharmacology of C-fibres. 1) Tachykinin receptor antagonists of peptide and non-peptide nature have been employed to identify the tachykinin receptors of the rabbit iris as NK1 and NK3 type

Periodic orbits of 3-d dynamical systems admitting a Poincaré section can be described as braids. This characterisation can be transported to the Poincaré section and Poincaré map, resulting in the braid type. Information from braid types allows to estimate bounds for the topological entropy of the map while revealing detailed orbit information from the original system, such as the orbits tha

Amerikansk animerad film har under sin existens lånat drag från karikatyrer, filmvärlden, minstrelshower, vaudeville, etniska skämt och nationella myter. Texten tar upp stereotypifieringen av svarta i amerikansk animerad film under 30- och 40- talen.

This chapter focuses on technology-brokers and inventors who operate in a medical context. It aims to discuss how relationships between the actors involved affect the possibility of transforming innovations into consumables, and to describe the kind of social work needed to successfully make this transformation. The chapter explores some of those tricks by using the concept 'net work' when discuss
