Phase Equilibria and Structures of Oppositely Charged Polymers and Surfactants in Water

Popular Abstract in Swedish Polymerer och tensider är två mycket vanliga molekylslag som vi ofta stöter på i vårt vardagliga liv. Polymerer är extremt långa kedjor sammansatta av tusentals repeterande enheter. De förekommer både som hårda material (t ex plast) och i lösning (t ex målarfärg). Det finns syntetiska polymerer, såsom nylon och polyeten, och det finns biologiska polymerer, t ex cellulosA new approach to the study of aqueous mixtures of oppositely charged polymers and surfactants has been introduced. Pure polyion-surfactant ion complex salts have been synthesized and used as the point of departure. The elimination of the simple ions reduces the number of components in the mixtures, thus greatly simplifying the system. By mixing the complex salt with either the polyelectrolyte or

The Swedish Model of Industrial Relations: Self-Regulation and Combined Centralisation-Decentralisation

The Swedish model of industrial relations is analyzed with respect to some closely related dimensions: collective agreements - legislation, cooperation - confrontation, self-regulation - state regulation and centralisation - decentralisation. Both the historical development and the present state of the model are discussed. In an analytical table the dimension self-regulation - state regulation is

Comparative aerodynamic performance of flapping flight in two bat species using time-resolved wake visualization.

Bats are unique among extant actively flying animals in having very flexible wings, controlled by multi-jointed fingers. This gives the potential for fine-tuned active control to optimize aerodynamic performance throughout the wingbeat and thus a more efficient flight. But how bat wing performance scales with size, morphology and ecology is not yet known. Here, we present time-resolved fluid wake

Marias medlidande: Ett bidrag till studiet av birgittinsk spiritualitet

The compassion felt by Mary for Christ when she was standing at the foot of the Cross is an important motif in late medieval piety. It becomes an object of liturgical celebration in the fifteenth century and sermons are preached on it. This paper treats the motif in some fifteenth century sermons from manuscripts once owned by the Birgittine abbey of Vadstena, Sweden. The treatment of the motif in

On the nature of the qualitative research approach

The qualitative approach to research is seen as a socially constructed heterogeneous tradition of ideas. It is difficult to argue for the existence of some set of features which are common to all qualitative methods but not to other types of research methods. Furthermore, it is unfortunate to see the qualitative approach as inherently in contrast to the quantitative approach. In fact, it may be fr

Studies of the fragmentation process in hadronic decays of Z⁰ boson

This thesis is based on the work that was done during 1992--1996 at the DELPHI detector at LEP. Its main parts are outlined below. The brief Introduction gives an overview of the science of Particle Physics, its development and contemporary status. The first chapter represents an introduction to the DELPHI detector at LEP, describing the main features of the LEP machine and the DELPHI detector a

Helicobacter pylori and Chlamydia pneumoniae in primary care- cardiovascular and gastrointestinal aspects

Popular Abstract in Swedish Helicobacter pylori och Chlamydia pneumoniae är två mycket vanliga smittämnen i den svenska befolkningen. De vanliga kliniska manifestationerna är magsår respektive luftvägsinfektioner. På senare tid har det också diskuterats huruvida de kan bana väg för sjukdomsmanifestationer även inom andra organsystem. I många fall har de studeras var för sig men betydligt mera sällHelicobacter pylori and Chlamydia pneumoniae are common infectious agents in the Swedish population, causing gastritis ulcers and respiratory infections. The metabolic syndrome is characterised by overweight, insulin resistance, hypertension, diabetes and dyslipidaemia. Sera from a patient cohort (n=531) originally examined in 1987-89 were investigated for previous infection of H. pylori and C. pn
