Popular Abstract in Swedish Vad pysslar kräftorna med? Kräftor äter allt! Jag har visat att kräftor äter gamla blad från träd, alger, vattenväxter och även smådjur som till exempel sländlarver, iglar och sövattensgråsuggor. Dessa olika typer av mat har olika näringsvärde. Om vi jämför med vad vi äter så är det ju uppenbart att t.ex. västerbottenpaj och kokta kräftor har olika näringsvärde. Pajen I show that crayfish consume detritus, algae, macrophytes, and an array of invertebrates. Crayfish were found to reduce invertebrate densities. However, prey mobility seemed to be a key factor regulating the strength of interactions between crayfish and prey. Since crayfish seek to maximize growth, they benefit from feeding on invertebrates, shown to promote high growth rates. I found crayfish to

538 vocalisations from three domestic cats were collected and used in a phonetic pilot study in order to test some recording and anal- ysis methods normally used with human speech. Based on auditive analysis, the vocalisations were categorised into five types and analysed for duration and F0. The most common type was a combined murmur and miaow. Similar mean type durations were found in all three

Most stars form in some sort of stellar cluster or association. In such clusters the number density of stars can be very high. Thus, single stars in such clusters may undergo frequent close encounters with other stars and exchange encounters with binary systems. The perturbation caused by the other star in a close encounter or by the companion star in a binary can have significant effects on the e

Abstract The present work investigates i) the occurrence and removal of pharmaceuticals at Swedish WWTPs, and ii) potential causes for differences in the removal efficiency of pharmaceuticals at wastewater treatment plants. Particular attention is directed at the biological treatment and the pharmaceutical removal capacity per unit biomass of activated sludges and carrier biofilms of different or

Strain has frequently been suggested to play an important role in the function of several proteins. In this paper, we review various definition of strain and discuss how it may be quantified. We show that covalent strain (i.e. strain caused by covalent interactions) plays a minor role for the function of all proteins we have studied, e.g. blue copper proteins, desulforedoxin, CuA in cytochrome c o

This paper studies regional museum, archives and arts education commissions of the Region of Scania, reformed in 2009, from a policy analysis perspective. It describes the background, design and implementation of the new policy and analyses its effects. The paper gives detailed information on the complexities of policy tool design and implementation, and discusses it in the light of regional gover

This study aims to provide a comprehensive overview of sustainability practices in food retailing sector. Report is structured to reflect on overall sustainability trends among European food retailers, outline drivers and barriers to address sustainability issues in retailer’s supply chain operations and provide classification of sustainability initiatives undertaken by EU retail organizations tha

Popular Abstract in Swedish Insulinberoende diabetes mellitus (IDDM = Typ 1 diabetes), och kronisk sköldkörtelinflammation - autoimmun thyreoidit (AIT) anses idag vara orsakade av att de hormonproducerande cellerna angrips av kroppens eget immunsystem (sk. autoimmunitet). När sjukdomen ger sig till känna kliniskt finnes antikroppar (sk. autoantikroppar) riktade mot cellkomponenter i det hormonprodThe two most common autoimmune endocrine diseases in children are autoimmune thyroiditis (AIT) and Type 1 (insulin-dependent) diabetes mellitus (IDDM). Autoantibodies (ab) can be found several years before clinical diagnosis in both diseases. The aims of this study were to investigate the prevalence of thyroid ab in children with IDDM and in children with allergic diseases; to study islet ab and t

The theory of nonequilibrium Green functions allows for a quantitative modeling of quantum cascade lasers. Explicit results are given for transport in a THz-laser and gain in a IR-Laser

Popular Abstract in Swedish Karaktäristiskt för människors påståenden om tidigare händelser och mer stabila fakta i deras omvärld är att de är förknippade med en viss grad av subjektiv säkerhet eller konfidens med avseende på om påståendena överensstämmer med vad som var eller är fallet. Ett exempel är ögonvittnens konfidens i påståenden om att ha pekat ut rätt gärningsman. Den grad av konfidens eTheoretical accounts and models of calibration typically explain the degree of realism (validity) in confidence and frequency judgments in terms of different cognitive and methodological factors. The present thesis demonstrates that also social factors are of importance for the degree of realism in these types of metacognitive judgments. The results of Study I showed improved realism in pairs’ con
