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
The attitude of teachers towards students can vary substantially in relation to different factors, such as educational background, pedagogical training, teaching methods, etc. In this paper, we explore the impact of negative role-models on future teaching. In particular, past experiences of teachers as students as well as the contextual influence of other teachers on their future teaching has been
We explore whether off-the-shelf accounting solutions are used or not used in management control. This study explores the usage of accounting solutions such as ERP, “hybrid ERP”, and “best-ofbreed” (BoB). Previous research highlights the problem that ERP has a “moderate” impact on management control but no study addresses whether hybrid ERP and BoB adopters experience the same problem. The explora
Popular Abstract in Swedish Avhandlingens syfte var att kartlägga den vård vårdpersonalen i Sverige praktiserar när nyfödda barn är döende och dör; samt belysa hur svenska kvinnor upplevt hot om och förlust av sitt nyfödda barn och vården de erhållit; ett ytterligare syfte var att utforska muslimska kvinnors uppfattning om den i Sverige praktiserade neonatala vården i livets slut. De professionelThe aim was to describe the neonatal end-of-life practice and illuminate Swedish women's lived experiences of the threat and the reality of their neonate's dying and death as well as the care received. A further aim was to explore Muslim women's view of current Swedish neonatal-end-of-life care. In a questionnaire with close-ended questions 144 registered nurses described their experiences, behavi
