Atmospheric dispersion represents a relatively overlooked problem in connection with the ultimate quality of ELT images corrected by adaptive optics (AO). The aim of this paper is to evaluate the contribution from atmospheric dispersion to the background level of the point-spread function (PSF). Since proper suppression of this level is important for the prospects for direct exo-planet observation

A selective and sensitive method is presented for biogenic amines (BA) determination. The novelty consists in coupling a highly selective electrochemical biosensor to a weak acid cation-exchange column for online detection of amines. A bienzyme design, based on a recently isolated amine oxidase from grass pea and commercial horseradish peroxidase, was used for the biosensor construction. The enzym

Syftet med denna studie är att utifrån mitt empiriska material kartlägga och beskriva hur de anställda på de särskilda ungdomshemmen tolkar, definierar, och upplever ett behandlingsprojekt, som involverade olika myndigheter, benämnt Motverka Våld och Gäng. Dessutom uppmärksammas hur de anställda samordnarna uppfattades och kategoriserades. I institutionspersonalens framställning är samordnarens The aim of this study is to map out and describe the way employees in Swedish juvenile homes interpret, define and perceive, on the one hand, the project “Motverka Våld och Gäng” meaning “Counteract Violence and Gangs”, and on the other hand the role of the Coordinators employed in this project. The role of the Coordinator is formally clear and unproblematic. The project management directives sta

Background: Up to half the residents of nursing homes for the elderly have asymptomatic bacteriuria (ABU), which should not be treated with antibiotics. A complementary test to discriminate between symptomatic urinary tract infections (UTI) and ABU is needed, as diagnostic uncertainty is likely to generate significant antibiotic overtreatment. Previous studies indicate that Interleukin-6 (IL-6) in

Background: This study investigates responses to requests for clarification in conversations between children/adolescents with cochlear implant (CI) and normally hearing peers. Earlier studies have interpreted a more frequent use of requests of confirmation (yes/no interrogatives) in the CI group as a conversational strategy used to prevent communication breakdowns and control the development of t

The scientific community has gratefully embraced floating-point arithmetic to escape the close attention for accuracy and precision required in fixed-point computational styles. Though its deficiencies are well known, the role of the floating-point system as standard has kept other number representation systems from coming into practice. The paper discusses the relation between fixed and floating-

A genetic algorithm for optimal placement of optical fibers in arbitrary geometries for interstitial photodynamic therapy has been developed. Based on calculated fiber positions, the diffuse light distribution is simulated by solving the diffusion equation by means of the finite element method and the treatment time is calculated. Utilizing an instrument for interstitial photodynamic therapy that

A number of researchers have attempted to define and encapsulate the essence of ‘critical research’. It has been suggested to encompass interpretation of social phenomena, and seeks for understandings that could support efforts to bring about beneficial change. It has been further suggested that such work is characterised by: concern with substantive social issues (e.g. power, values); foundation

Beskrivning ges av analysteknik (protoninducerad röntgenstrålning), provtagningsteknik (kaskadimpaktor av Battelle-typ) och provberedningsteknik. Utfört arbete i form av provbehandlingsförbättringar, konstruktion och förbättring av provtagare, bestämning av lämpliga analysparametrar samt uppbyggnad av ett dataprogramsystem presenteras.

In this paper we present a novel method for predictive coding with application to transmission of speech over packet-switched networks. Our method uses multiplexing to distribute a part of the information about a segment of each speech signal in several data packets while keeping the data packet rate and payload for that part of the information unchanged. We investigate three multiplexing schemes:

Popular Abstract in Swedish Denna studie handlar om interpersonell kommunikation mellan barn och vuxna i särskolan. Specifikt inriktas den på att studera den kommunikation som sker när de kommunikationssätt som parterna använder är teckenspråk och tecken och samtidigt tal. I fokus är elever med hörselnedsättning och utvecklingsstörning, vilken är en liten, unik och outforskad elevgrupp, men också Pupils with impaired hearing and moderate to severe learning difficulties usually go to special schools for the severely learning disabled. Few studies have been conducted on the interpersonal communication among these pupils. The all-embracing aim of this study is to look closer into the communication that takes place during the school day between children and adults, in cases where Sign Language

The objective of this study was to identify possible changes in mRNA and protein expression of high-mobility group box protein 1 (HMGB1) and its suggested receptors - receptor for advanced glycation end-products (RAGE) and Toll-like receptor 2 (TLR2) and TLR4 - in human cervix during pregnancy, term and preterm labor. Cervical biopsies were taken from 58 women: 20 at preterm labor, 24 at term labo

Popular Abstract in Swedish Vilket lands domstolar är behöriga att lösa tvister som kan uppkomma till följd av elektroniska avtal där parterna hör hemma i olika länder? Vilket lands lag skall domstolen använda? Även om en svensk domstol är behörig är det inte säkert att den skall använda svensk lag. Dessa frågor sorterar inom ett ämnesområde som heter interationell privat- och processrätt. I avhanThis study addresses some of the private international law perspectives on electronic commerce, namely the matters of jurisdiction and choice of law. Electronic commerce is based on the formation of contracts, and when there are contracts, questions regarding legal issues arise. A distinctive trait of electronic business is that its activities are not bound by geographic borders in a traditional s

In this paper, we propose a new system-level design language, called SystemJ. It extends Java with synchronous reactive features present in Esterel and asynchronous constructs suitable for modelling globally asynchronous locally synchronous systems. The strength of SystemJ comes from its ability to offer the data processing and encapsulation elegance of Java, Esterel-like reactivity and synchrony,

This paper presents the concept and initial work on a microfluidic platform for bead-based analysis of biological sample. The core technology in this project is ultrasonic manipulation and trapping of particle in array configurations by means of acoustic forces. The platform is ultimately aimed for parallel multistep bioassays performed on biochemically activated microbeads (or particles) using su
