The heat of wetting of regenerated cellulosic fibres (TENCEL (R), Viscose and Modal) was investigated by reaction calorimetry in comparison with cotton, polyester and TENCEL (R) Fabric. Reaction calorimetry is a technique applied for measuring the heat evolved in chemical reactions where very high analytical precision is required Before the measurements, the fibre samples were dried in an oven at
Popular Abstract in Swedish Studien beskriver och analyserar strategisk förändring i tre svenska tidningsföretag. I studien beskrivs hur företagen utvecklades från enaffärs-verksamheter till multiaffärs-verksamheter. Studien pekar på hur denna utveckling framförallt ska ses som resultat av etableringen och spridningen av en ny kunskapsformation. Ett centralt innehåll i den kunskapsformationen var The dissertation examines power and knowledge in strategic changes. It is a study of changes in three Swedish newspaper companies which developed from single-business to multi-business corporations. It is suggested that this transformation was based upon the establishment and reproduction of a new knowledge formation. This knowledge was the knowledge of strategy, particularly the classical perspec
In search for a possible explanation of the phenotypic heterogeneity in selective immunoglobulin (Ig)A deficiency, we studied the IgG2 antibody response to meningococcal polysaccharide A (PSA) in IgA-deficient (IgAd) individuals after vaccination with meningococcal A + C polysaccharide vaccine. Two groups of IgAd individuals, one frequently infected and one clinically apparently healthy, as well a
Neisseria gonorrhoeae, the causative agent of gonorrhea, is a natural infection only in humans. The resistance of N. gonorrhoeae to normal human serum killing correlates with porin (Por)-mediated binding to the complement inhibitors C4b-binding protein (CUP). The entire binding site for both porin molecules resides within complement control protein domain 1 (CCPI) of C4BP. Only human and chimpanze
Mechanical force is generated within skeletal muscle cells by contraction of specialized myofibrillar proteins. This paper explores how the contractile force generated at the sarcomeres within an individual muscle fiber is transferred through the connective tissue to move the bones. The initial key point for transfer of the contractile force is the muscle cell membrane (sarcolemma) where force is
Popular Abstract in Swedish Spridning och inavel i naturen I modern tid har vi människor orsakat stora förändringar i miljön, vilket påverkat många arters livsbetingelser. Exempelvis har vi avskogat stora områden och efterlämnat små delar av de större områden som tidigare hängde ihop. Organismer som lever i sådana uppsplittrade miljöer kommer att vara isolerade från varandra, vilket får som följdTo evaluate how inbreeding affects the viability of small populations, it is crucial to determine what constitutes a population (i.e., the number of breeders in local patches and the degree of dispersal), and also to estimate the reproductive consequences of philopatry and emigration. In this thesis, I concentrate on dispersal, inbreeding and fitness in natural populations. I consider dispersal ra
Popular Abstract in Swedish Hjärtinfarkt och kärlkramp orsakas av förändringar i hjärtats kranskärl pga åderförkalkninng (ateroskleros). Fettinlagring i kärlväggen leder dels till förträngning och dels till bildning av ömtåliga plack som plötsligt kan spricka. Denna kärlväggsskada försöker kroppen reparera genom aktivering av blodets levringssystem (koagulation). Det är i denna situation inte heltThe triggering mechanism in myocardial infarction (MI) and unstable angina involves coronary thrombus formation following plaque rupture. Coagulation is initiated by tissue factor that activates factor VII (FVII), and is inhibited by protein C and its co-factor protein S. Resistance to activated protein C (APC resistance) is a common risk factor for venous thrombosis caused by a mutation in the ge
Popular Abstract in Swedish Föreliggande avhandling syftar till att närmare undersöka neuropsykologiska funktioner hos patienter med psykossjukdom och baseras på fyra studier avseende förstagångsinsjuknade patienter i psykos inom Fallskärmsprojektet. Projektet genomfördes vid 17 psykiatriska kliniker i Sverige och patienterna erbjöds en "behovsanpassad" psykiatrisk behandling, huvudsakligen i öppeThe present thesis is based on studies of neuropsychological functions in first episode psychosis patients (FEP) from the Swedish multicenter study, the Parachute Project. The thesis aims to clarify neuropsychological functions in psychotic illnesses. Patients from the project were examined neuropsychologically, using the WAIS-R NI test battery, in relation to measures of outcome in terms of clini
The outer membrane protein Ail of Yersinia pestis mediates several virulence functions, including serum resistance. Here, we demonstrate that Ail binds C4b-binding protein (C4BP), the primary fluid-phase regulator of the classical and lectin pathways. Non-covalent binding of C4 and C4b to Ail was also observed. C4BP bound to Ail can act as a cofactor to the serine protease factor I (fI) in the cle
Optogenetic techniques provide powerful tools for bidirectional control of neuronal activity and investigating alterations occurring in excitability disorders, such as epilepsy. In particular, the possibility to specifically activate by light-determined interneuron populations expressing channelrhodopsin-2 provides an unprecedented opportunity of exploring their contribution to physiological and p
Streptococcal toxic shock syndrome is frequently caused by Streptococcus pyogenes of the M1 serotype. The aim of this study was to determine the role of Ras-homologous (Rho)-kinase signaling in M1 protein-provoked lung damage. Male C57BL/6 mice received the Rho-kinase-specific inhibitor Y-27632 before administration of M1 protein. Edema, neutrophil accumulation and CXC chemokines were quantified i
We have recently shown in both herpesviruses and phages that packaged viral DNA creates a pressure of tens of atmospheres pushing against the interior capsid wall. For the first time, using differential scanning microcalorimetry, we directly measure the energy powering the release of pressurized DNA from the capsid. Furthermore, using a new calorimetric assay to accurately determine the temperatur
Taking the exhibition "Art in the Streets", which was shown at The Geffen Contemporary at the Museum of Contemporary Art, Los Angeles from 17 April to 8 August, 2011, as its main point of departure, the present article discusses street art's association with the institutions of the art world. "Art in the Streets" sparked a lot of debate before, while and after it took place. The article primarily
Perceived control is of significance in occupational therapy, as revealed in empirical research and suggested in practice models. This study investigated the relationship between perceived control and occupational performance in persons with long-term mental illness. The 177 participants were assessed regarding perceived control (locus of control and self-mastery) and occupational performance (act
Rationale, aims and objective The objectives were to describe and evaluate the structured medication questionnaire and to improve data handling of results from the Morisky four-item scale for patient compliance and Beliefs about Medicines Questionnaire-specific (BMQ-specific). Methods A questionnaire was developed with the purpose of being used when identifying medication errors and assessing pati
Optimal management of the commons to ensure sustainability relies on community management. Despite widespread knowledge of this, conventional wisdom is locked into how much the state should regulate the market. Free market ideology, defined as neoliberalism, promotes a culture of extreme competition and individualism which stand in contrast to the needed cultures of participation and inclusion for
