SynopsisOptimized structures describing key features of the potential energy surface for water exchange at three planar d8 centers have been calculated using ab initio density functional theory. The local density approximation (LDA), including relativistic corrections for Pt, gives good agreement with the available experimental ground state structural data. LDA binding energies together with expli
The article is a discussion of works by two Danish composers who both, with self-constructed instruments challenge computer music both as genre, the understanding and use of conventional technology and the relation to history. At first glance, the use of the homemade instruments appears as a common characteristic. But, when one takes a closer look, different discourses and various discussions of m
The purpose was to investigate (i) how people with psychiatric disabilities who attend day centres experience their quality of life (QoL) compared to non-attendees, (ii) differences in QoL between those who attend meeting place-oriented centres and those who attend work-oriented centres, (iii) possible correlates of QoL among day centre attendees. Ninety-three day centre attendees and 82 non-atten
Caveolae are abundant adipocyte surface domains involved in insulin signaling, membrane trafficking and lipid homeostasis. Transcriptional control mechanisms for caveolins and cavins, the building blocks of caveolae, are thus arguably important for adipocyte biology and studies in this area may give insight into insulin resistance and diabetes. Here we addressed the hypothesis that one of the less
Ultrafiltration and nanofiltration have become common methods to treat surface water for drinking water purposes. Common aims of a membrane step are removal of natural organic matter (NOM), softening or adding an extra microbiological or chemical barrier. In most cases, the membrane is considered a good disinfection step; commonly the viral removal is at least 4–log. To ensure a working disinfecti
Popular Abstract in Swedish Som man kan se av titeln handlar den här avhandlingen om polyelektrolytgeler. Vad är nu polyelektrolyter och vad är geler? Och vad är de bra till? Polymerer Polymerer är långa molekylkedjor, som förekommer i naturen men som också kan vara gjorda av människan. Några exempel på polymerer i naturen är DNA, som bär på vår genetiska information, stärkelse och cellulosa. Nå
Wear in forming tools and contact problems between sheet-metal and tool-material are common problems in manufacturing industries and sheet-metal-parts production. In this paper recent tool material experiences are presented. Quantitative determination of wear has been performed using micro hardness indentions made on the tool surface prior to pressings and thereafter measured. Wear tests are perfo
The coexistence of two lamellar liquid-crystalline phases in equilibrium for binary surfactant-water systems is a rare and still puzzling phenomenon. In the few binary systems where it has been demonstrated experimentally, the surfactant is invariably ionic and the miscibility gap is thought to stem from a subtle balance between attractive and repulsive interbilayer forces. In this paper, we repor
Fruit and vegetable processors, faced with the challenge of gaining and maintaining a healthy position in the competitive fruit and vegetable sector, are optimising traditional processes towards product quality. Using frozen potatoes as a case study, the aim of this study was to evaluate the potential of improving the texture of potatoes by modifying the processing conditions. The texture of proce
BACKGROUND: Questions have been asked about whether the process of obtaining informed consent from parents to clinical trials on neonates leads to valid consent. We undertook a study in nine European countries to assess this issue and to seek any practical improvements. METHODS: Semi-structured interviews were conducted with parents of 200 babies who had been asked for consent to neonatal trials a
Background/aim: People with profound cognitive disabilities are not expected to learn powered mobility use. The Driving to Learn project focussed on what this population could achieve from practising in a joystick-operated powered wheelchair. By means of using grounded theory methodology an eight-phase process 'growing consciousness of joystick-use' was identified. In addition, a tool for assessme
Operating the HCCI engine with dual fuels with a large difference in auto-ignition characteristics (octane number) is one way to control the HCCI operation. The effect of octane number on combustion, emissions and engine performance in a 6-cylinder SCANIA truck engine, fuelled with n-heptane and isooctane, and running in HCCI mode, are investigated numerically and compared with measurements taken
OBJECTIVE: To develop a psychometrically appropriate brief symptoms measure of carpal tunnel syndrome (CTS). METHODS: Preoperative CTS 11-item symptom severity and 8-item functional status scales from 693 patients (71% women) with CTS were subjected to exploratory factor analysis and item response theory (IRT) analysis yielding a revised CTS symptoms scale. A validation sample of 213 patients (68%
Popular Abstract in Swedish Ett nytt betygssystem infördes i grundskolan i Sverige 1995. Det tidigare relativa eller normrelaterade systemet ersattes av ett kriterierelaterat, benämnt det mål- och kunskapsrelaterade betygssystemet. Övergången till kriterierelaterade bedömningsprinciper ställer nya och andra krav på lärare. I denna studie undersöks lärares sätt att erfara betygssystemet och dess ti
Background— Carotid intima-media thickness (IMT) is increasingly used as a surrogate marker for atherosclerosis. Its use relies on its ability to predict future clinical cardiovascular end points. We performed a systematic review and meta-analysis of data to examine this association. Methods and Results— Using a prespecified search strategy, we identified 8 relevant studies and compared study des
Mycoprotein from the fungi Fusarium Venenatum A3/5 has been used as a meat alternative for a long time but little attention has been paid to the waste it creates. When the fungi is fermenting it uses a lot of water which is sent to the drain after the process is finished. This water contains large quantities of both nutrients and biomass. As circular economy is becoming more important for environm
