By using absorption and fluorescence (steady-state and time-resolved) techniques the interaction between a poly(acrylic acid) PAA, randomly grafted with pyrene (Py) units (PAAMePy55) and a triblock copolymer of poly(ethylene oxide) and poly(propylene oxide) (EO20PO68EO20, P123) was investigated. From the fluorescence data it is shown that upon addition of P123 a decrease of the (pyrene-pyrene, Py-

The dynamic phase diagram of triethylene glycol dodecyl ether (C12E3) in D2O was determined for 40, 50, and 60 wt % of surfactant. The shear flow effect on the nonionic lamellar phase was investigated as a function of temperature and concentration. The transition from planar lamellae (L-alpha)-to-multilamellar vesicles (MLVs) was characterized by means of rheology, rheo-small-angle neutron and lig

Extracellular High Mobility Group Box 1 (HMGB1) has been associated with acute and chronic inflammatory conditions. However, little is known about HMGB1 in necrotizing bacterial infections. We hypothesized that the local HMGB1 response is excessive in severe soft tissue infections (STIs), which are characterized by necrosis and hyperinflammation. To explore this, tissue biopsies were collected fro

The association between a randomly pyrene labeled PAA polymer (PAAMePy55) and a PEO-PPO-PEO triblock copolymer (P123) in aqueous solutions of different NaCl concentrations and pHs has been studied by means of dynamic light scattering (DLS) and steady-state fluorescence spectroscopy at 40 °C. At acidic pH values, in the low P123/PAAMePy55 molar ratio regime (i.e., at low P123 concentrations), the r

Background The Chemotaxis inhibitory protein of Staphylococcus aureus (CHIPS) blocks the Complement fragment C5a receptor (C5aR) and formylated peptide receptor (FPR) and is thereby a potent inhibitor of neutrophil chemotaxis and activation of inflammatory responses. The majority of the healthy human population has antibodies against CHIPS that have been shown to interfere with its function in vit

We investigate the properties of multifractal products of the exponential of stationary diffusion processes defined by stochastic differential equations with linear drift and certain form of the diffusion coefficient corresponding to a variety of marginal distribution.

Popular Abstract in Swedish Den här avhandlingen innehåller fyra uppsatser som på ett eller annat sätt relaterar till befolkningsströmningar såsom dess ekonomiska konsekvenser och orsaker. I den första uppsatsen används en hushållsundersökning från Kina för att undersöka huruvida utbildning bidrar till att höja inkomsterna hos hushåll i jordbrukssektorn. Genom regressionsanalys uppmäts korrelatioAbstract Population movements are more substantial today than at any other point in human history. If managed effectively, migration can be beneficial for all aspects of social and economic life. This thesis contains four papers, all of which are related to the economic consequences and determinants of migration, within and across countries. The first paper employs a household survey to explore

Context The relationship of platelet function testing measurements with outcomes in patients with acute coronary syndromes (ACS) initially managed medically without revascularization is unknown. Objective To characterize the differences and evaluate clinical outcomes associated with platelet reactivity among patients with ACS treated with clopidogrel or prasugrel. Design, Setting, and Patients Pat

The high variability of the HIV envelope glycoproteins (Env), and their heavy glycan coating, contributes to the limited host immune control. Still, broadly neutralizing antibodies (bnAbs) are found in some chronically infected HIV-infected individuals, which has spurred the research on antibody-based vaccines. An important tool in detecting and studying bnAbs, are neutralization assays. Here we d

This thesis is an empirical study of how positioning is achieved in interactional Swedish. Positioning has previously been described in terms of epistemic modality, interpersonal positioning, stanceand speech act adverbials. The aims of the study are, firstly, to identify what linguistic resources are used to achieve positioning in interaction. A second aim is to describe where in the turn-con

Karyotype structures of Scenedesmus acuminatus (Lagerch.) Chod. and Scenedesmus pectinatus Meyen are compared. The karyotype of S. acuminatus (n = 5) is described for the first time. It reveals four large metacentric and one large submeta centric chromosomes (4M + 1SM). The established karyotype differences have been helpful in clarifying the taxonomic position of these two species. The cytologica

This study aims to research how honour is explained and defined by social workers and thus increase the knowledge about the concept itself, and the negative consequences it can have on an individuals’ life. By interviewing (both in a group interview, and in a one-on-one interview) professionals who daily are coming into contact with honour codes and context, and letting them give their view on the

This thesis investigates the Danish public service station DR and the national structure of the media. As the democratic process has increasingly moved from the national level to the EU and as Danes rely on television as the main source of information on European political matters, it is only reasonable to expect the national public service station, DR, to fulfil that role, nonetheless previous st

Persuasive Technology, technology that is designed to change users’ attitudes or behaviors, has been exercised for a long time. Designing a technology that can change users’ attitudes or behaviors is a process that needs to be carefully thought through. Captology makes this process easier by defining the most important factors that technology needs to contain in order to be classified as Persuasiv

När den Europeiska ekonomiska gemenskapen bildades genom Romfördraget fanns inga uttryckliga hänvisningar till skyddet för de grundläggande rättigheterna. Den här uppsatsen beskriver framväxten av regelverket för de grundläggande rättigheter som har utvecklats av EU:s rättsväsende och lagstiftare i nära samarbete med medlemsstaterna och Europarådet. Målet med denna framställning är att presentera The Treaty of Rome which established the European Economic Community contained no explicit references to the protection of fundamental rights. This thesis describes the emergence of an EU acquis covering the field of fundamental rights developed by the EU judiciary and legislators in close cooperation with the Member States and the Council of Europe. The objective of this essay is to present the a

How will future developments in insulation affect current construction standards? Will it help to facilitate better construction solutions and slimmed-down designs? What price is reasonable for new insulation materials and what can be achieved with some of the newest features? With today's focus on environmental protection and improving environmental standards, energy efficiency in buildings h

Hur många gånger har du tagit på dig en svart tröja och sedan upptäckt hur varmt det blir när solen tittar fram? Med hjälp av den erfarenheten är det säkert tydligt att mörka material värms upp mer av solens strålar än ljusa material. Man säger att mörka material ”tar till sig”, eller absorberar, en större andel av den strålning som solen sänder ut i form av ljus. Det som inte absorberas kan istälHuman population on Earth is increasing and is projected to continue increasing for many years to come. Most of the increase will probably occur in cities and the extent of urban areas will increase with it. As cities grow larger and new cities are built, the many and diverse climatic effects of urbanization will become more evident. A specific climatic effect of urbanization which has not receive

The new Civil Protection Act takes a more holistic view at accident prevention and protection than previous fire and safety regulations. The level of detailed regulation has decreased and national performance objectives have been formulated instead. The main purpose of this report is to present proposals for how municipalities, systematically and effectively, can plan and conduct inspection activi
